Abstract

According to the invention are subsequently mounted on buildings with thermal insulation to be attached functional parts with spacers. For the spacers, drill holes are made in the insulation and in the building wall.

Description

The invention relates to spacers and fasteners for through a facade through to be fastened to buildings parts. All buildings have a facade. The façade often includes thermal insulation and before that a plaster layer or other non-load-bearing layer.
Subsequently, the task often arises of attaching essential parts to the building. These include in particular canopies, awnings, advertising systems, escape routes, scaffolding, lamps and surveillance cameras and the like. Some of the parts have a considerable weight.
All parts must withstand considerable wind loads.
To attach the facade profiles and facade panels threaded rods are anchored as spacers in the building, the length of which is such that they protrude in front of the building through the thermal insulation and also protrude to a degree relative to the thermal insulation, for the attachment of the front of the facade fixing parts is required.
The threaded rods are mostly M12 rods. That is, there are rods with 12mm outer diameter and a metric thread on the circumference. Such threaded rods have a certain load limit. Larger loads are distributed to a corresponding plurality of threaded rods.
The threaded rods are usually glued into corresponding holes in the building. To do so, drilled holes in the building wall by existing thermal insulation, then introduced adhesive and pressed the threaded rods in the adhesive. In rarer cases, the building walls are pierced to hold the threaded rods on the inside of the building with rondels.

The invention has recognized that the threaded rods form thermal bridges and that their selection and installation is often inadequate. The defects include inaccurate positions of the threaded rods, misalignment of the threaded rods and too much or too little protruding of the threaded rods compared to an existing thermal insulation.
When choosing threaded rods with too low strength, the threaded rods bend under the load of the parts to be fastened.

An older proposal is based on the task of facilitating a defect-free attachment of the parts.

On the conventional fasteners can improve much after the older proposal, if not only a hole is drilled in the insulation, as it is required for mounting the threaded rod in the building, but a hole is drilled, at least three times the diameter of the threaded rod , preferably at least four times the diameter, and more preferably at least five times the diameter of the threaded rod.
Preferably, the bore is first made through the thermal insulation into the building, which is conventionally required for the dowel and the adhesive. This hole is drilled in the insulation to the extent described above. In this case, the drill can serve as a guide, which is provided for the smaller hole in the building.
The drill for the insertion of the threaded rod bore is regularly a stone drill. These are drills with a carbide tip. There are such stone drills in the market, which can be severed when drilling in concrete and its concrete steel reinforcement. However, the drilling progress is significantly reduced when the masonry drill hits the reinforcing steel reinforcement.
By contrast, the tool for the production of the larger bore in the insulation, for example, a slightly executed pot drill or a milling cutter.
Alternatively, there is also a combined tool consisting of the stone drill and the pot drill. Then the pot drill can be mounted on the stone drill bit.
After drilling, at least one cleaning of the borehole is provided in the building wall to produce a clean adhesive surface.
The larger hole in the insulation is used after the older proposal to screw after gluing the threaded rod in the building a gain (amplifier) on the threaded rod and to clamp against the building wall. The takes place advantageously in the area in which the threaded rod is exposed to the largest bending load. The ability of the threaded rod is used to absorb much more tensile load than bending load. By the reinforcement and tensioning described above, a part of the tensile strength of the threaded rod is used to reduce the bending load.

The reinforcement, may be an annular thickening with a corresponding bearing surface on the building wall. Preferably, the diameter of the reinforcement is equal to the inner diameter of Bore in the heat insulation minus a play that is necessary to screw the thickening through the hole on the threaded rod.

The reinforcement may be a cylindrical sleeve with a collar towards the building wall and an internal thread in the sleeve. The collar serves as a support; the internal thread for screwing.
The reinforcement may be in one piece or composed of several parts.
The advantage here is a closing edition of the reinforcement on the building wall.
For full-surface edition, a processing of the building wall at the borehole is favorable after the older proposal. This can be done with a face milling cutter, which has a hole in its center, so that the cutter can be pushed over the already glued threaded rod. The threaded rod then gives the router the grip and guidance for accurate milling work.

Optionally, the annular or cylindrical reinforcement is provided with a collar which has a narrow edge on the building wall side. Then, the edge forms the interface with the building wall and reduces the milling work to prepare for the attachment of the reinforcement to a fraction of the required for a full-surface contact of the collar on the building wall milling work, namely on the corresponding to the edge of the collar of the reinforcement Building wall surface, an annular narrow strip.
In particular, adhesive that swells out of this when penetrating the anchor in the borehole, can remain so within limits. Limiting means that too much adhesive must be removed, however, the removal of the excessive amount of adhesive does not require special care on the surface enclosed by the annular contact surface described above.

Alternatively, to leveling the contact surface for the reinforcement of the threaded rod on the building wall and a gluing of the reinforcement can be done with the building wall.
The gluing of the reinforcement can be done after bonding the threaded rod in the borehole. The gluing can also be done simultaneously with the gluing of the threaded rod.

For subsequent bonding, the adhesive is placed between the reinforcement and the building wall. There forms at the interface a layer of material to which the reinforcement can rest properly without a processing of the surface would have to take place with a cutter. In addition, the bonding creates a connection between the reinforcement and the building wall. This adhesive joint relieves the threaded rod or takes part of the effective load forces in the case of load.

Depending on the adhesive used, the adhesive between the building wall and the reinforcement unfolds particularly high adhesive forces when the reinforcement is stretched against the building wall. Such adhesives are sensitive to pressure. In order to make optimal use of such adhesives, it may be advantageous to prevent the distortion that strong torques act on the gain. This can be achieved by avoiding a rotation of the reinforcement during the clamping process. For example, this is a gain that is not screwed, but only plugged and has a correspondingly large hole instead of a threaded hole that surrounds the threaded rod or the anchor at least a small distance. Then, the clamping force can be transmitted to the reinforcement with a nut without the risk of entrainment of the reinforcement. In this case, the use of a washer with low reinforcing side friction and / or low screw nut side friction may be advantageous. The washer can optionally be provided with edges at the same time, which protrude from the edge of the nut and at the same time with respect to the head of the reinforcement and can be folded after the tension with one part around the head of the reinforcement and with the other part around the nut. This creates an additional backup of the reinforcement and the nut against loosening.

In the other variant of the joint bonding of threaded rod and reinforcement in a single gluing process as much adhesive is optionally filled in the well that when mounting the threaded rod with the pre-mounted reinforcement so much glue swells out of the well that at a desired gap of For example, until 3mm the entire gap is filled with glue. With little routine, the necessary filling of the well can be achieved by hand with a sense of proportion without any other means. The filling of the gap is then recognizable by the fact that the adhesive swells when positioning the threaded rod with the preassembled reinforcement at all edges of the reinforcement out. The size of the resulting gap between the building wall and the reinforcement is insignificant.
Advantageously, deviations of the building wall from the vertical can also be compensated in such layer formation. The adhesive layer then forms a leveling layer for unevenness of the Building wall and deviations of the building wall from the vertical. This facilitates an exactly horizontal mounting of the threaded rods.

The adhesive is preferably the same as that used for gluing the threaded rod. A suitable adhesive is, for example, a gel-type, solvent-free two-component adhesive based on epoxy resin with a cycloaliphatic polyamine hardener. Such an adhesive is commercially available, for example, under the name Akepox 5010. The advantage is a minimal shrinkage during curing of the adhesive.

For every bonding of the reinforcement to the building wall, rough, dust-free adhesive surfaces are an advantage. In addition, even individual recesses in the contact surface of the reinforcement and / or in the building wall can be advantageous. Then the glue penetrates into the depressions. Thickenings in the adhesive layer between the reinforcement and the building wall form, which increase the resistance of the bond against loosening when torques act.

On good (flat and vertical) building walls, both preparation of the contact surface with a milling cutter and the application of an intermediate layer can be dispensed with if mounting of the reinforcement is provided without adhesion to the building wall. Then the building wall itself provides a level, vertical contact surface for a support of the reinforcement on the building wall.
As described above, the reinforcement is braced against the building wall.
Either the reinforcement is provided with an appropriate for the threaded rod internal thread. The reinforcement can then be rotated on the threaded rod until the desired tension is achieved. With a lock nut, the reinforcement can be secured in the respective Anspreßstellung on the building wall.
Or the central hole in the reinforcement is formed as a through hole and the clamping is done with a nut on the threaded rod. In addition, a backup of the pressing position can be done by means of a lock nut.

For the bracing are one-piece or multi-part spanner, which engage with a tubular part on the threaded rod and are adapted to the front end of the tubular part of the nut or lock nut or optionally engage in suitable recesses of the reinforcement. To the Spannschlüssel also includes a lever arm, with which the torque is applied for the tension.
It is favorable if the lever arm is at the same time designed as a ratchet and can therefore be moved back and forth during clamping.
It is also advantageous if the lever arm is also provided with an indication of the torque. This can ensure that the bond of the threaded rod is not overloaded when bracing the reinforcement.
It is also advantageous if the threaded rod has a profiling such as a reinforcing steel rod at the area reaching into the borehole. Then the threaded rod can regularly record much more torque than a threaded, engaging in the borehole part of the threaded rod.
The threaded rod can then also be referred to as an anchor.

Furthermore, in the case of adhesive-free contact the building wall for non-rotatable arrangement of the gain favorable when the gain at the interface with the building wall has a profiling that gives the touch surface high friction with the building wall, better still causes a claw in the building wall. Then less clamping forces to secure the reinforcement on the building wall are required.

The reinforcement causes a stiffening of the threaded rod.
The further the reinforcement protrudes in the thermal insulation, the greater the stiffening of the threaded rod.

Preferably, it is at least provided that the stiffening in the longitudinal direction of the threaded rod has a dimension which is at least equal to 1/3 of the thickness of the thermal insulation, even more preferably has a dimension which is at least equal to 0.5 times the thickness of the thermal insulation, and most preferably a Measure that is at least equal to 2/3 of the thickness of the insulation.

The reinforcement can consist of concrete.
The reinforcement can be made of steel.
Preferably, the reinforcement consists of a high strength plastic with low heat transfer coefficient compared to other materials. High-strength plastics are referred to DD242194 . DD142166 . DD140120 . DE 102014102826 . DE102015007004 . DE102014115506 . DE4214636 . DE1504463 . EP567845 ,

The low heat transfer coefficient is advantageous for the insulation.

The reinforcement can taper with increasing measure in the direction of the threaded rod, because the bending load for the reinforcement becomes smaller with increasing distance from the building wall. This results in a cavity in the borehole of the thermal insulation. According to the older proposal, this cavity is filled after assembly of the spacer with the same or similar material from which the thermal insulation consists.

Optionally, the reinforcement has a cylindrical body instead of the tapered body. On the attachment of the reinforcement with cylindrical body has no significant influence. The advantage of the cylindrical shape of the reinforcement lies in the filling of the borehole in the thermal insulation. Optionally, the remaining cavity, which results in thicker thermal insulation with the same cylindrical shape of the reinforcement is filled by other cylindrical body with the same threaded hole or through hole as the reinforcement. These further cylindrical bodies may have the same or a different thickness as the reinforcement provided on the building wall side. With the different thicknesses, the borehole can be filled to the edge of the thermal insulation. However, it is also possible to let the cylindrical body with respect to the thermal insulation to protrude or leave behind. The respective position results from the connection of the spacer with the parts to be mounted in front of the facade.
The additional cylindrical parts preferably consist, like the building-wall-side reinforcement, of a non-foamed, high-strength plastic. Depending on the burden of the connection of the spacer with the parts intended for attachment in front of the facade also less solid plastic, including foamed plastic for the production of other cylindrical body can come into question.
The additional cylindrical parts are then optionally glued to the cylindrical reinforcement and / or screwed to give the construction even more strength.
In conventional training of the spacer with a continuous threaded rod protrudes the threaded rod for the connection with the parts to be fastened in front of the facade relative to the thermal insulation.

Although there are still systems with a threaded rod that extends through the entire thermal insulation and protrudes up to the thermal insulation to form a connection for the parts to be mounted in front of the facade. However, this creates a heat transfer from the building via the threaded rod to the facade.

Usually, the heat transfer problem is solved by thermal decoupling.
For thermal decoupling reference is made to DE202011050195 . DE102011051510 . DE102010061139 . DE19653672 . EP2853654 . EP2540924 , There each intermediate piece is provided with low heat conduction between parts of high heat conduction.

In application of this technique, it is known to divide the threaded rod and insert a heat-insulating intermediate piece of non-foamed, high-strength plastic at the division point.

When filling a borehole in the insulation with the cylindrical reinforcement and one or more other cylindrical bodies, at least one of the cylindrical body is provided instead of through holes at both ends centrally with a trained as a threaded hole blind hole after the older proposal. With this cylindrical body, a thermal decoupling is possible. To do this, the threaded rod is split. One part is intended for bonding in the wellbore and protrudes from the wellbore to be bolted to a cylindrical body. Thereby a screwing takes place in a blind hole. In the other blind hole, the other part of the threaded rod is screwed, which then protrudes in front of the facade for connecting the parts to be fastened in front of the facade.

The part provided with the blind holes may also be formed by bonding two cylindrical threaded parts provided with through-threaded holes with an intermediate part without through-hole.

Although the tapered reinforcement is material-saving and meets all the requirements, if the heat insulation to be penetrated have the same thickness or only a few different thicknesses of relevant thermal insulation must be taken into account and / or the differences in thickness of the relevant thermal insulation are low.
This does not fully take into account the increasing demands on thermal insulation. When the first facades were insulated, thicknesses of 60mm and 80mm were considered sufficient. The demands on the thicknesses have changed constantly over the years. In the meantime, thicknesses of 200mm and more are discussed. Finally, having agreed on the necessary thickness of thermal insulation, the system with the tapered reinforcement may be sufficient for the future.
In the past, however, many structures with lower and very different thermal insulation have been created. According to the older proposal, a system is to be created that is suitable for very different insulation thicknesses.
According to the older proposal, this is achieved with the variable-length reinforcement.
Advantageously, for example, a variable length reinforcement may be the same length as the threaded rod conventionally projecting out of the building wall.
Or the reinforcement may have a dimension equal to the thickness of the thermal insulation.
Or the reinforcement may have a dimension that is less than the thickness of the thermal insulation.
The extensibility of the reinforcements opens up various advantages for the assembly.

The variable-length reinforcement preferably consists of reinforcing parts which can be pushed into one another and pushed apart or screwed into and out of one another. Such reinforcing parts have over the length at least partially the same dimensions. In order to secure the thermal insulation at the same time, the length-adjustable reinforcement parts consist at least partially of plastic with low heat transfer. The necessary strength of the construction is achieved by the use of high-strength unfoamed plastics.

Sliding can be various profiles. Favorable are hollow sections, in particular tubes, which can surround a threaded rod. Clamps and pins or the like can prevent inadvertent adjustment of the profiles

Screw parts regularly have a circular cross-section. Preferably, pipes with pins or pipes with pipes are combined.
Even more preferably, the pins are provided building wall side or connected to the building wall and the pipe sits with a screw on the pin. At least the tube is made of heat-insulating plastic.
When using two threaded with one another sitting pipes sitting in the connection with male thread inside in the other, internally threaded tube. Each of the two pipes can sit on the building side. At least the pipe forming the connection to the building exterior wall consists of heat-insulating, high-strength plastic. Optionally, the tubes can be made of several layers of different materials to increase the load capacity.

The pins are preferably provided with a collar and a central opening. With the central opening, the pins are plugged or screwed onto a threaded rod / anchor, which projects in comparison to the conventional threaded rods only a fraction of the building wall.
It is advantageous if the pin is provided for screwing with a molded-nut. Molded means that during the shaping of the pin in a mold cavity, the nut is placed in the required position and the nut is enclosed by the plastic (leaving the screw holes open). Incidentally, the pin is provided with the external thread required for screwing to the further reinforcement part.
The pin can be clamped alone in the form generally described above for reinforcements with the threaded rod glued into the wellbore, are glued alone or glued and braced.
The threaded rod does not have to protrude much farther from the borehole than is required for bolting to the journal. It can, however, continue to protrude.

The pin is preferably made with a collar, if the necessary diameter for a pipe corresponding to the pin in the outer diameter can be significantly smaller than the necessary contact surface and footprint of the pin on the building wall. If the diameter of the tube within the wellbore in the thermal insulation can be significantly larger, also results in a much larger spigot diameter. Then the pin can be used without a collar application. But then the pin diameter still remains to a certain extent smaller than the inner diameter of the borehole in the thermal insulation. The certain amount is at least equal to twice the wall thickness of a Internal threaded pipe for screwing to the pin, which then has a small collar or no collar. In the latter case, the pin has a cylindrical body with external thread

The corresponding pipe with the pin is preferably provided at one end with an internal thread for screwing with the pin and closed at the other end and provided with a connection for the building to be fastened parts. At this end, the pipe has such a large thickness that it can withstand the stresses of attaching the part to be fastened in front of the facade. In the closed pipe end sits a threaded rod, so that a connection of the front of the facade to be fastened parts as in conventional spacers is possible.
The threaded rod is held in the closed tubes on both sides of the closed end with nuts.

The screwing of the tube with the pin allows any change in length in the given by the thread length limits. Preferably, at least one ventilation opening is located at the closed end of the tube. If it is seen that the limit is exceeded and no adaptation to extremely thick thermal insulation is possible, for example, another pin can be used, which has a greater length, so that the spacer described above will fit for larger thermal insulation thicknesses.

When using a further tube instead of the pin, a tube (inner tube) is provided, which has an external thread and by means of the external thread with the pipe previously described in connection with the pin length changeable screwed. The intended instead of the pin pipe (inner tube) is closed at the building wall end and is like the pin clamped or glued or clamped and glued to the anchor. For accessibility of the screw provided for the bracing the building wall facing away from the end of the pipe provided for the pin is open.

In a further embodiment, the inner tube and the surrounding outer tube are arranged reversed. Then the outer tube with the internal thread in the spacer Gebäudewandseitig arranged and the inner tube with the external thread as the tube is arranged in combination of pin and tube.

The spacer may also consist of two pins and a sleeve. Then, the building-wall-side pin can correspond to the above-explained in the combination of pin and tube pin and also can be handled. That is, this pin can be glued or screwed or glued and screwed to the building wall.
On this building wall side pin the sleeve is screwed. The sleeve corresponds to the tube in the combination of pin and tube described above. Unlike the tube, the sleeve is internally threaded throughout and open at both ends. When the sleeve is screwed onto the building wall side pin, so is the opposite end of the sleeve open. In the open end of the sleeve of the second pin is screwed. The second pin has, unlike the first and building-side spigot no central through-threaded hole. At the second pin a blind hole is provided with an internal thread. In the blind hole sits a piece of threaded rod and protrudes so far that the second pin provides a same connection for front of the facade to be fastened parts as conventional spacers.
The blind hole is not mandatory. The same can be achieved with a through threaded hole in the second pin, with a longer threaded rod piece and a nut. Then the threaded rod piece can be locked with the nut in the second pin.
Preferably, the two pins are the same except for the pin length, so that, for example, the shortest first pin can also be used as a second pin and vice versa. Incidentally, cones of greater length may be provided in adaptation to large thermal insulation thicknesses.
The pins can initially be turned out of solid.
With a larger spigot requirement, welding on of extension pieces pays off on the spigot.
For very large demand figures, the production in an injection mold also counts for the different cones.

As an alternative to the pins with different lengths, it is possible to always use the same pin and to use longer sleeves when a need for adaptation to larger thermal insulation thicknesses. Optionally, the sleeves are made to do so as longer sleeves, the length being such that by division at least two shorter useful sleeves each are formed.
It is also possible to produce shorter sleeves, which can be welded together to form longer sleeves.

For safety reasons, all bolted parts are additionally secured once again in the screw position. Preferably, the screw thread with which the pins, tubes and sleeves are adjustably connected, blocked after reaching the correct Schraubstellung by an adhesive on the thread. Preferably, this is a two-component adhesive application, which cures with sufficient delay. Alternatively or additionally, existing cavities can be filled in the spacers. This is, for example, mounting foam.

The load capacity of the spacers described above is much greater than the load of conventional spacers.
In comparative experiments, the load was measured in kilonewtons (kN) at the end of an M12 threaded rod spaced 140mm or 160mm, 180mm or 200mm from the building wall at the head of the threaded rod due to bending to a vertical deflection of 1mm comes.
As a result, the same deflection spacer described above must be loaded about 5 to 8 times higher than the strongest conventional spacer. In detail: distance 140mm 160mm 180mm 200mm conventional 0,37kN 0,254kN 0,179kN 0.13 kN Senior proposal 2,291kN 1,339kN 1,151kN 0.98 kN If an awning is to be subsequently attached to a building wall with 200mm thermal insulation and the attachment of the awning should be able to withstand 5kN including possible wind loads, then suffice with the above-described attachment / spacers 5 attachment points, while in the conventional attachment with 40 attachment points must be expected , With so many fixing points, the question must be answered as to whether the building wall still has sufficient strength in the area of the awning.

For mounting the spacers described above, for example, the following parts and operations are used:

• a) a drill, with the heat insulation through a hole in the building wall is introduced
• b) a crown drill or pot drill or milling cutter with which the bore is drilled in the thermal insulation in order to lay the foundation for further process steps
• c) an end mill, with which the building surface in the area of the bore is milled to a defined

The building wall may have various texture consisting of concrete, brick, perforated brick, hollow block, sandstone, aerated concrete and the like.
The crown drill provided here has a sleeve, one end of which forms a cutting edge. Centered in the sleeve a bore adapted to the guide is provided, which protrudes sufficiently far from the sleeve to effect a guide in the insulation and in the borehole. The sleeve picks up the material cut out by it. Without the guide, the crown drill would correspond to a known core drill core drill bit, where a core is drilled out of a material.

The threaded rod has the function of an anchor.
Instead of the threaded rod and other anchors can be used, for example, rods which are formed in the region of the bore like reinforcing steel and in the region of the screw with the spacer thread.
When inserting the threaded rod / anchor, the use of a tool of advantage, with the threaded rod / anchor held and can be performed exactly in the middle of the hole. As a tool, for example, is a mandrel comprising the threaded rod / anchor at the threaded end, so that a short threaded rod / anchor can be pushed through the hole in the insulation in the hole in the building wall.

In this case, a cone / funnel can be helpful, which is positioned on the mandrel, that it rests in the bore in the thermal insulation when the threaded rod / anchor has reached the predetermined position in the bore of the building wall. As a result, the cone / hopper prevents skewing of the threaded rod / anchor and the cone causes a position accuracy for the threaded rod / anchor in the longitudinal direction of the bore.
After solidification of the adhesive, the mandrel can be removed again from the threaded rod / anchor.

It is advantageous if the milling of the seat for the spacer takes place on the building wall after gluing the threaded rod / anchor.
Then a leaked from the hole in the building part and in the meantime solidified adhesive mass can be removed with.
As a router, an end mill is used. This cutter has a hole in the middle, which is adapted to the diameter of the threaded rod / anchor. In addition, the outer diameter of the cutter is adapted to the diameter of the bore in the thermal insulation.
As a result, the cutter is guided at work on the threaded rod / anchor and in the bore in the thermal insulation.

For screwing the building-side Abstandshalterteiles different solutions are available.
A solution provides that in the building-side spacer member a corresponding thread or a nut or other insert is recessed with an internal thread, which is adapted to the thread of the threaded rod / anchor. In this case, the nut / insert of the plastic material of the building-side spacer member is enclosed so that the loads from the attachment of the parts are safely passed over the spacer and the threaded rod / anchor in the building.

The preparation of a building-side spacer member is preferably carried out by injection molding in a mold in which the nut / insert is positioned before filling a liquid plastic melt.
As far as the occurring loads are passed without nut / insert of the spacer on the threaded rod / anchor, a reinforced plastic is preferably provided for the building-side spacer member. As a reinforcement, for example, high-strength fibers can be used, which are einmischbar in a liquid plastic melt. Even fibrous fine wires are suitable as a reinforcement.
The mixture can also be molded by injection molding into the building-side spacer part.
Such trained spacer member is rotated during assembly for connection to the threaded rod / anchor.

Another solution for the screw connection provides that the building-side spacer member can be plugged during assembly without rotation on the protruding from the building part of the threaded rod / anchor. For screwing with the threaded rod / anchor, a nut / insert can be loosely inserted into the building-side spacer part. The building-side spacer member has for this purpose a sufficiently large opening, for example in the form of a bore, and the building side a covenant. The nut / insert can be screwed onto the threaded rod / anchor, so that the building-side spacer member is clamped with the edge against the support surface on the building.
For screwing the nut / insert a mandrel is optionally provided again. The mandrel may include the nut / insert.
The insert can also be designed as the nut of a socket set. Nuts of a socket set are components that are suitable on one side for receiving a screw head or a nut and have on the opposite side a recess into which a socket wrench can engage.
Optionally, the nut / insert also form a special component; For example, a sleeve which has a thread at one end and at the other end is adapted to receive the mating end of a socket wrench. Such a socket wrench may for example be designed as Allen key or be a square key.
Usually, a ratchet is part of a socket set. With a ratchet a socket wrench can be moved back and forth and still a screw or a nut can be moved only in a selected direction of rotation. This is made possible with a ratchet, which is installed in the head of the ratchet and engages only in the selected direction of rotation in a ring gear and connects the ratchet arm with the sprocket or slides in the other direction of rotation on the teeth of the sprocket.

Preferably, the bolting of the spacer in each of the embodiments discussed above is controlled with the threaded rod / anchor. This can be done by a torque wrench is used after a preliminary tension of the screw. The torque wrench can be placed on the socket wrench and transmits only a preselected torque on the socket wrench.

The belonging to the spacer further part is preferably also made of plastic, more preferably of the same plastic as the building side spacer member.
The further spacer member has the corresponding thread to the thread of the building-side spacer member. If the building-side spacer member has an external thread for the screw connection with the further spacer member, the thread of the further spacer member is an internal thread. The situation can also be reversed. Then the external thread is located on the further spacer part and the internal thread on the building-side spacer part.
Optionally, the thread is a fine thread.

The screw remains in the application of a fine thread even in the desired screw position when a screwing of the other spacer member is done with a part to be fastened.
In case of doubt, the selected screw position can be additionally secured. As a fuse is suitable for example a lock screw. The spacer can also be drilled through in the bolting area and a pin inserted into the hole. It can also be given a setting adhesive on the thread in the setting of the spacer, so that the curing adhesive blocks the screw. The adhesive is preferably a two-component adhesive and is chosen so that the time to curing of the adhesive is long enough to set all spacers to the desired level.

For screwing the other spacer member with the part to be fastened sits in the end of the further spacer member a threaded pin. The threaded stem may be molded, as discussed above in connection with a molded nut / insert. The threaded pin can also be screwed.

In order not to hinder the setting of the spacer, it may be expedient to ventilate the cavity in the spacer. These are, inter alia, ventilation holes, which are introduced in the axial direction in the head of the further spacer member.
Optionally, the vent is used after the setting of the spacer at the same time for filling a curing agent, with which the spacer is secured against an adjustment.

Optionally, a rosette / cover for covering the spacer head is provided between the spacer and the part to be fastened. It is advantageous if the rosette / cover at the same time engages over the facade, so that penetration of moisture between the thermal insulation and the spacer is prevented. This prevents damage to the facade during frost.
The seal can still be increased with a sealing washer between the rosette / cover and the facade.
Optionally, the rosette / lid is also glued to the facade.

Instead of the screwed spacer also another length-adjustable spacer is possible, which is designed in the manner of a hydraulic piston / hydraulic cylinder. A conventional hydraulic cylinder engages around the piston and is acted on at least one side with hydraulic fluid until the piston occupies a certain position. Thereafter, the hydraulic line is blocked and the piston remains in the desired position. According to the older proposal, a liquid adhesive or other material is filled instead of hydraulic fluid, which solidifies and locks the piston in the desired position in which the piston or its piston rod protrudes to the desired extent from the cylinder.

Advantageously, a simple plastic material can be used for the cylinders and the pistons, because the cylinder and the piston undergo substantial solidification due to the filled-in adhesive. The cylinder and the piston may consist of unilaterally closed with lids pipes of different diameters, so that the one tube can be pushed with its open end in the open end of the other tube. The covers of the tubes can be provided for mounting with the provided anchors or threaded rods / threaded pin with corresponding openings. With conventional viscous nature of the adhesive openings may well have such a large play of movement that the anchor or threaded rods / threaded pin easily slide through the lid.
The lids may be welded or held in the tubes solely by mechanical forces.
Preferably, in the lid, which is remote from the wall of the spacer, there is also an opening for introducing the adhesive.

Optionally, only a single tube is used as a spacer, that is cut to length in place of longer pieces of pipe and immediately has the desired length of the spacer. Then piston or other tubes are unnecessary. The one tube is closed with lids, as explained above in another embodiment.

For all gluing processes:

Before bonding, the adhesive surfaces are carefully cleaned, for example with a compressed air lance or with a suction lance, which is guided into the bore. Optionally, compressed air lance or suction lance is provided with a brush, are replaced with the parts that are not sufficiently connected to the building wall.

The bonding can be done in a conventional manner by first pressing a suitable, solidifying adhesive and then the threaded rod into the borehole. The bonding can be carried out using a conventional adhesive cartridge, wherein it is advisable to first prepare a plurality of boreholes, so that a glue cartridge can be used as far as possible.

Optionally, a separate small adhesive cartridge can be placed in each well, which is then destroyed by pressing the threaded rod and releases the adhesive that surrounds the threaded rod and solidifies.

It can also be glued a dowel in the hole into which the threaded rod is screwed.
The bond causes despite spreading a lasting hold of the anchor. The attachment described above has the advantage of a very low cost even with a small number to be set dowels with the cartridges.

After the new development, the adhesive gives the expansion dowel the necessary hold. The power development may be eliminated, which is required on conventional expansion dowels for generating a sufficient pressure against the wall of the hole for the dowel or for frictionally locking the dowel in the hole. The spreading process can end when the dowel touches the hole wall on all sides, but no significant pressure has yet been deployed against the hole wall. This can be easily recognized by the fact that a further resistance builds up against the further spreading. Advantageously, therefore, a lighter Find screw application. The lighter screw may be made of a lower strength material or have a smaller diameter.

For the glue consumption is also advantageous if the expansion dowel is provided at least one end, better still at both ends with a resilient edge.

The edge may be fixed or be integral with the rest of the dowel or slidably mounted on the dowel. The displaceable arrangement allows an adaptation of the adhesive surface on the dowel to the hole wall. This is particularly advantageous for thin plasterboard walls.

The border may be, for example, a thin lip. The lip may have different cross-sectional shapes, for example the shape of a compliant bead or the shape of a thin compliant ridge. With the lips, the length of the cavity to be filled with adhesive is limited in the hole for the dowel.

For the glue consumption is also advantageous if the diameter of the hole for the dowel is chosen as low as possible. In this case, a movement play for inserting the anchor into its hole and a sufficient flow area for the adhesive are taken into account.

The adhesive cartridge can be arranged in the dowel or on the dowel jacket. One or more adhesive cartridges may be provided for a dowel. When using multiple adhesive cartridges the same adhesive cartridges can be used for different dowels by the differences of the dowels by changing the number of adhesive cartridges is taken into account.

The adhesive cartridge can surround the dowel outside hose-shaped. Then the adhesive cartridge is double-walled and arranged the adhesive between the inner shell and outer shell.

Preferably, adhesive cartridges with a simple tubular or tubular jacket are used. Such glue cartridges can be arranged as individual cartridges in Dübelinneren. Such adhesive cartridges can be bundled for an arrangement in Dübelinneren also to several or embedded in the dowel jacket individually or in several.

The housing of the adhesive cartridges may consist of different materials. This includes, for example, plastic. Plastic films can be produced cheaply and processed favorably. Of particular advantage is the easy weldability of plastic films in the production of the adhesive cartridges and closing the glue cartridges after filling.

Plastic films may also contain components that protect the adhesive from solar radiation or other environmental influences.
For particularly high requirements, plastic films can be combined with other materials. These include metal foils. The metal foils form particularly resistant layers against the ingress of water vapor or other media; as well against radiation exposure.

Even more preferably, the adhesive cartridges are provided with a predetermined breaking point. The breaking point includes a weakening of the adhesive cartridge shell, so that the adhesive breaks at a corresponding pressure load on the cartridge at a predetermined and releases the adhesive.

If the adhesive cartridges are arranged within the expansion dowel, it is advantageous if the expansion dowel is slotted in the usual manner over a certain length in the longitudinal direction to allow the spreading. The glue must flow through the slots. Therefore, a sufficient flow area for the adhesive is to be considered for the slots.

For gluing various adhesives are suitable.
Preferably, an at least partially curing adhesive and / or an adhesive mixture is used in which one adhesive component has a mortar base and another adhesive component has a plastic base. The mortar base should positively affect the adhesion to the building material of the building part, the plastic base adhesion to a plastic dowel.

Also common adhesives such as PU adhesive come into consideration. For PU adhesives, a distinction is made between 1-component adhesives (one-component adhesives) and 2-component adhesives (two-component adhesives). PU glue exist from isocyanate and polyol. The two components are filled together in a pressure vessel and together with a propellant, so that they emerge again at an opening of the container. For small quantities, the container is a can. For large quantities, the container is correspondingly large.
To react, the two components still need water. The water can be humidity or other moisture. The 1-C PU adhesives cure on reaction with the water. When the water is removed from the ambient air, it will harden from the outside to the inside. Curing usually takes several hours on the way. In contrast to the 1-component PU adhesive, the components of a 2-component PU adhesive react when mixing the components. 2-component PU adhesives generally have greater strength than 1-component PU adhesives.

PU adhesives (two-component adhesives) cure by polyaddition reaction. Other adhesives with the same reaction are epoxy adhesives. These adhesives are called resin and hardener. EP adhesives have advantages in the application to metals.

Other adhesives cure by polymerization.
Such adhesives are often based on methyl methacrylate.
These adhesives are characterized by very short reaction times.

When using two-component adhesives, the above-described use of several cartridges in a dowel or on a dowel opens the possibility of combining differently filled cartridges. In the one cartridge can then be contained one reaction component and in the other cartridge at the other reaction component.

A preferred embodiment of the dowel has a sleeve-shaped body, which is preferably slotted at several times at one end. For example, three slots extending in the longitudinal direction of the sleeve are provided. The remaining segments between the slots have inwardly directed bulges / indentation, can be partially inserted into the adhesive cartridges.
The adhesive cartridges may already be prepared at the factory and glued in the inwardly directed bulges of the dowel shroud to simplify the dowel handling.
The inward curvature narrows the sleeve opening. If the dowel with the adhesive cartridges is placed in a corresponding hole in a building and a screw is rotated through the sleeve opening, there is a widening of the sleeve in the area of the adhesive cartridges. At the same time, the adhesive cartridges are pressed against the wall of the hole until they burst and the adhesive is released.

The screw is optionally similar to a wood screw formed with a sufficiently long tip that easily penetrates between the bulges of the sleeve, so that the screw engages well between the bulges.
The final diameter of the screw then determines the degree of deformation of the adhesive cartridges. The adhesive runs in the cavity between the dowel and hole wall and also through the slots in the remaining cavity between the screw and dowel inner wall. After curing of the adhesive, the dowel sits firmly in the building. The dowels and adhesive cartridges can also be used independently of the spacers in buildings application.

Optionally, the screw is coated with a release agent to which the adhesive does not adhere, so that the screw can be unscrewed at will and screwed in again and optionally replaced with another screw or a hook or eyes or the like. A suitable release agent is, for example, silicone or Teflon.

The anchors and threaded rods are optionally made of stainless steel. This prevents the anchors and threaded rods from corroding by moisture.

Incidentally, it is advantageous if the spacer is coated with a fire retardant.

Optionally, the spacers described above and the operations provided for it also apply to vertical installation variants such as doors, windows, facade elements, suspended ceilings, pipe systems, air conditioning systems and the like components, which are mounted hanging or standing.

The invention has for its object to apply the gain of the older proposal to previously known spacers. In particular, all spacers that come with a rod in grab a borehole and carry at the end protruding from the well an attachment or Vorbauteil on the facade. The reinforcement of the rod according to the invention considerably increases the load capacity of the spacer. Such spacers load a building wall much less than a continuous thicker rod with the same bending strength as the spacer according to the invention.
Especially stressful for a building wall are brackets that are attached to a building wall with several, slightly spaced screws / anchors. This can cause large-scale breakouts on the wall. Similarly problematic are expansion dowel trained anchor.
With the expansion dowel each building wall is loaded after insertion of the expansion anchor to stretch. Mineral building walls can absorb strain loads only to a small extent, in contrast to pressure loads. According to the invention, the conventional anchors are exchanged for an optimized for the bonding anchor or the conventional Spreitzdübel anchor are additionally glued. Optionally, this can be used to tighten the anchor formed as expansion anchors less strong.

• -mit einem Innengewinde auf dem Anker verschraubt werden. Dies hat den Vorte daß eine thermische Trennung innerhalb der Verstärkung erfolgen kann. Dazu besteht die Verstärkung aus wärmeisolierendem Kunststoff und ist der Anker innerhalb der Verstärkung unterbrochen. Das heißt, der Anker besteht aus einem gebäudewandseitigen Teil und einem Teil, der dem vorgesehenen Anbau oder Vorbau zugewandt ist. Zwischen beiden Teilen besteht innerhalb der Verstärkung ein Abstand. Diese Stellung wird durch die Klemmung des gebäudewandseitigen Ankerteils, die Verklebung der Verstärkung mit der Gebäudewand und durch die Verspannung des anderen Ankerteiles mit dem Anbau oder Vorbau erreicht. Wahlweise können alle verschraubten Teile zusätzlich durch Kontermuttern und andere Sicherungseinrichtungen gesichert werden.
• -oder wird die Verstärkung mit entsprechendem Spiel über den Anker geschoben die Spannung mit Hilfe einer Schraubenmutter erzeugt, die auf den mit Außengewinde versehenen Anker aufgeschraubt wird.

The clamping is carried out as in the above-explained clamping operations and subsequent clamping operations preferably with a screw. The anchor has an external thread and can reinforce

• - be screwed with an internal thread on the anchor. This has the advantage that thermal separation can take place within the reinforcement. For this purpose, the reinforcement consists of heat-insulating plastic and the anchor is interrupted within the gain. That is, the anchor consists of a Gebäudewandseitigen part and a part that faces the intended extension or stem. There is a gap between the two parts within the reinforcement. This position is achieved by the clamping of the building-wall anchor part, the bonding of the reinforcement with the building wall and by the tension of the other anchor part with the attachment or stem. Optionally, all bolted parts can be additionally secured by locknuts and other security devices.
• -or the reinforcement is pushed over the armature with a corresponding clearance, the tension is generated by means of a nut which is screwed onto the externally threaded armature.

With the lower voltage, the strain load for the building wall is reduced. Regardless of the combination of expansion anchors and bonding in anchors has advantages when the adhesive threatens to fall out of the anchor hole under its weight or threatens to take even an undesirable position. The expansion anchor then serves as an assembly aid by preventing a change in position of the anchor until the adhesive has developed sufficient strength The falling out / outflow can indeed be counteracted with an adhesive that have a special early strength. Such adhesives are more expensive than ordinary adhesives and may also have other disadvantages over normal adhesives. Situations in which the anchor threatens to fall out of the anchor hole, can result in vertically suspended arrangement of the anchor or tilted arranged anchors. An undesirable change in position may result without sufficient early strength of the adhesive even with a horizontal arrangement of the anchor.

By spreading the anchor, each anchor can be given a sufficient hold in the anchor hole, which allows to use even adhesives with very low early strength.
Advantageously, the necessary spreading forces are so small that even the simplest and easiest spreading mechanism sufficient for the positioning of the anchor in the borehole.

There, where a building wall has the necessary strength for a Spreizdübel, can remain an expansion dowel or apply. Then it is still advantageous to strengthen the protruding from the borehole anchor rod according to the invention.
There are different rods with which the expansion dowels can be spread. It is advantageous if the rods are profiled at the top. For example, the tip can carry a screw thread and / or be conical.

There are also rods and screws that can be knocked into the hole without dowels and clamp in it. A special profiling of the rods and screws can help. However, this solution has similar disadvantages as the expansion dowel. If, however, is held on such rods, a reinforcement according to the invention is also advantageous here.

The relevant dowels / anchors also include injection anchors, in which adhesive is pressed over the dowel into the borehole in the building wall. Even with such dowels, the inventive reinforcement of the protruding from the well rod is beneficial.

Among the known prior art spacers also include those in which held in the hole anchor at the protruding end behind the facade cladding with a head, but show only the anchor rod between the head and the building wall.
In the application of reinforcement from the earlier proposal, the anchor is then provided in the area between the building wall and the head with a reinforcement. The reinforcement may have a ring shape or sleeve shape or conical shape or a special shape. As a special form, for example, a sleeve with a building-wall-side collar to create a larger contact surface is to be regarded.

There are also anchors that do not end in the building wall, but go through a building wall / are inserted through and
provided on the inside wall side with a head which forms an abutment for the bracing of the armature. Also in this armature system, the reinforcement according to the invention is advantageous on the armature part projecting out of the building exterior wall. The reinforcement not only increases the load capacity of the anchor. The reinforcement also allows another type of tension, namely a tension of the armature on the building inner wall.

Preferably, the reinforcement is braced at least on the building wall. The reinforcement can rest loosely against the wall or be glued to the building wall. For loose concerns on the wall is a plane and parallel contact surface of the building wall advantage. The plane and parallel contact surface can be ensured by processing the building wall.
When gluing the reinforcement to the building wall, a plane and parallel contact surface is dispensable. The adhesive causes an advantageous contact surface. The adhesive compensates for any imperfections in the contact surface. In addition, the bonding has the advantage of direct introduction of loads of reinforcement into the building wall.

The anchor is provided for clamping between the building wall and the head with an external thread. The annular or sleeve-shaped reinforcement has a corresponding internal thread.

When gluing the reinforcement to the building wall, the adhesive filled into the drill hole is also used to bond the reinforcement. The amount of adhesive is then such that when positioning the anchor in the well sufficient adhesive from the well swells out to allow bonding with the reinforcement. For the simultaneous bonding in the borehole and on the building wall is advantageous if the anchor for mounting the reinforcement with the spreading means or other clamping means described above is held until sufficient solidification of the adhesive in the borehole. The clamping devices can be of the simplest nature. The simplest clamping devices can be small wedges. Since the task of the wedges can be limited to the positioning of the anchor until solidification of the adhesive, a pressing of the wedges by hand may be sufficient. Optionally, the wedges at least on the surface of an open-pore material with coarse pores, so that a mechanical clamping of the adhesive is ensured in the wedges and no adverse displacement of the adhesive can be done from the surface of the anchor.

For the positioning of the anchor can be helpful if for the gain a small depression is incorporated into the building wall, in which the reinforcement can penetrate. The incorporation can be done for example with a pot cutter, which engages with a guide in the previously formed well. Optionally, a simultaneous production of the borehole and the depression takes place. Then the pot cutter sits on the drill.
Due to the partial penetration of the reinforcement into the building wall, the loads acting on the reinforcement can partly pass directly from the reinforcement into the building wall.

The recess may be cylindrical or conical. The contact surface of the reinforcement is then adapted to the recess in the building wall. That is cylindrical with a cylindrical recess and conical with a conical recess.

Optionally, the reinforcement is mounted prior to solidification of the adhesive. For this purpose, the reinforcement may already be screwed onto the armature, so that the reinforcement is positioned together with the armature.

The bonding can also be done in two sections; first the gluing of the anchor in the borehole, then the gluing of the reinforcement on the building wall.
The adhesive for the bonding of the anchor in the well as well as for the bond between the building wall and the reinforcement can be applied or applied with a hand press or with one or more cartridges.
The cartridge contains a certain amount of adhesive and is destroyed by penetration of the anchor into the well so that the adhesive flows between the armature and the borehole wall. The amount of glue can be well dosed with the cartridges.
The introduction of the adhesive with a hand press leads with low exercise to a satisfactory dosage of the adhesive. In addition, the dosage of the adhesive can be significantly facilitated by the fact that special hand presses are used. The particular hand press is made, for example, from conventional hand presses with a housing and a toothed rod, which presses on the movable piston of the cartridge and is actuated by a ratchet-like lever mechanism. By repeated actuation of the lever, the rod is repeatedly pushed by a distance dependent on the lever path in the cartridge, so that the contents of the cartridge is gradually pushed out. The rod is then provided with graduation marks / a scale which allow the degree of indentation of collapse to be retained in the cartridge when a desired adhesive filling has been achieved in a borehole. In subsequent adhesive filling in other holes, the previously determined level of piston movement can be easily met again. This is all the more true if the marking lines / scale is provided with a consecutive numbering.

For every bond, it is advantageous to clean the adhesive surface on the building wall so that loose particles are removed which could impair the bond. For cleaning a strong suction may be sufficient.

When bonding the reinforcement, adhesive cartridges between the reinforcement and the building wall can also be used to dose the amount of adhesive. The positioning of the cartridges is optionally facilitated by attachment of the cartridges to the interface of the building wall or the reinforcement.
Optionally, the adhesive is applied only in the form of a circulating bead with the hand press on the contact surface of the building wall or the reinforcement. The run-down of the adhesive on the contact surface of the building wall or the reinforcement is prevented with a correspondingly liquid adhesive optionally with a ring or cuff. The ring / sleeve is made of flexible material, preferably made of plastic foam, which can give in the bracing of the reinforcement. Of particular advantage are rings of coarse-pored and foam (foam part) with open pores or coarse-meshed textile, in particular coarse tissue, or mat material or the like.

It is advantageous to use an annular foam part and annular mat part between the building wall and the reinforcement. The foam part or mat part is at least partially filled with adhesive, so that the compression causes the adhesive to escape. The emerging adhesive can come into contact with both the building wall and the reinforcement and make an adhesive bond with the building wall and / or with the amplifier.
The filling can be done with a cartridge, which is positioned in the foam part or mat part and is destroyed upon compression of the foam part or the mat part and releases the adhesive. The cartridge can be positioned just before mounting the reinforcement. The foam part or mat part can also be prepared with the cartridge at the factory. The cartridge may be made of different materials, preferably plastic. To ensure that the cartridge bursts on compression, the cartridge can be provided with a predetermined breaking point. The predetermined breaking point is formed by preferably by a pre-marked weak point in the jacket of the cartridge. Such a weak spot arises, for example, with a groove in the shell of the cartridge.
The foam part or mat part can also be filled with glue at the factory. Premature curing of the adhesive can be prevented by encapsulation of the foam part or the mat part. For example, a film is suitable for the encapsulation. To use the filled with adhesive foam part or filled with adhesive mat part, the film is peeled off.

Also for an adhesive-filled foam part or mat part, a sleeve can be advantageous, which encloses the foam part or mat part at the periphery. The film coating can then be limited to the end faces. After removing the film from the faces of the foam part and mat part are ready for use immediately.

The collar or ring is optionally made of a flexible film. The film can be easily squeeze when mounting the reinforcement.

During assembly, the annular foam part (ring of foam) or the annular mat part (ring of mat) is pushed onto the previously set anchor and then pushed the reinforcement on the anchor.

Optionally, the annular foam part or the annular mat part is preassembled on the reinforcement. The pre-assembly can be done by an adhesive connection. In this case, the annular foam part or mat part rests against the reinforcement, for example. Optionally, the ring or sleeve surrounds the building-side end of the amplifier. Advantageously, the adhesive may be pressed into the ring prior to assembly of the ring.

When gluing the reinforcement, excess adhesive can be forced out of the gap between the building wall and the reinforcement. Usually that is harmless. However, if this is undesirable, precise metering of the adhesive and / or the cuff will help.

Optionally, the compression of the foam part or mat and / or cuff is limited. For this purpose, for example, a spacer may be incorporated in the annular foam part or annular mat part, so that the compression is limited, for example, to a maximum of 80% based on the initial thickness or a maximum of 70% or a maximum of 60% or a maximum of 50% based on the initial thickness.

The above bonding technique is also true for the older spacers after PCT / EP2017 / 314 advantageous.

To avoid uncontrolled squeezing of adhesive from the gap between the building wall and the amplifier, an annular pad with enclosed adhesive or other material may be suitable, which solidifies, pushed onto the anchor and positioned between the building wall and the reinforcement. As the solidifying material, particularly suitable are materials having a solidifying agent contained in a destructible cartridge. The cartridge is destroyed when tightening the reinforcement on the building wall, so that the desired solidification sets only with the distortion of the reinforcement against the building wall.

Preferably, an adhesive bond with the building wall and / or with the reinforcement is provided on the cushion. This can be done by additionally applied adhesive. But this can also be done by the enclosed adhesive, in which the cushion wall-side and / or reinforcing side in the cushion cover is completely or partially permeable to adhesive, so that the adhesive spreads in the compression of the cushion at these contact surfaces. This can be accomplished with individual apertures distributed at the contact surfaces. It is also possible to set a general permeability. Preferably, this is done by selecting a fabric with a corresponding mesh size. The selection can be made with a few tests by subjecting different fabrics to a material of similar toughness as the intended adhesive and pressure. If the material is too small, the test is repeated with a mesh of larger mesh size. Conversely, if too much material is passed through, the test is repeated with a tissue of smaller mesh size.

The cushioning technique makes it possible to apply a substantially higher pressure to the adhesive layer when bracing the reinforcement on the building wall than with the previously described foam layer or mat. This can bring significant advantages for the solidification of the adhesive.
The cushion has like the annular foam layer or annular mat a central, the anchor shape adapted opening with which the pad is pushed onto the anchor.

• -die für den Abstandshalter vorgesehene Bohrung in der Fassadendämmung um so viel größer als der Außendurchmesser der Verstärkung bemessen
• -und das Kissenvolumen so groß bemessen,

daß eine gewünschte Fußbildung an der Verstärkung durch das Kissen erfolgt. Vorzugsweise kommt eine Ausbreitung auch um 20 bis 40mm in Betracht. Bei einem Durchmesser der Verstärkung von 60 mm ergibt sich dadurch eine um 20 bis 40mm größere Bohrung in der Fassadendämmung und gebäudewandseitig ein Fuß von 80 bis 100mm Durchmesser an der Verstärkung, der zur Biegefestigkeit der Abstandshalterkonstruktion erheblich beiträgt.
Am Umfang ist das Kissen wie auch der Umfang des ringförmigen Schaumteils oder der ringförmigen Matte vorzugsweise dem Umfang der Verstärkung angepaßt. Vorzugsweise ist der Außendurchmesser des ringförmigen Kissens höchstens gleich dem Außendurchmesser der Verstärkung.
Vorzugsweise ist in dem Kissen ein Abstandshalter vorgesehen, der die maximale Zusammendrückung begrenzt. Die maximale Zusammendrückung kann 80% oder 70% oder 60% oder 50%, bezogen auf die Ausgangsdicke, sein. Vorzugsweise erfolgt die Beschränkung mit Hilfe eines Abstandshalters, zum Beispiel mit einem in das Kissen eingelegten Ring mit größerem Innendurchmesser als die Durchgangsöffnung in dem Kissen, so daß der Ring im montierten Zustand des Kissens den Anker umgibt. Wahlweise kann der Ring dabei die Kissenwand an der Durchgangsöffnung bilden oder in einigem Abstand den Anker umgeben .
Die Zusammendrückung kann auch in Abhängigkeit vom Spanndruck beim Verspannen der Verstärkung erfolgen.The circumference of the pad as well as the circumference of the annular foam member or the annular mat may be different. Conceivable is a small size compared to the gain.
The circumference may also be greater than the amount of reinforcement. As long as the adhesive in the pad or in the annular foam member or in the annular mat is still flowable, the larger pad may even be inserted into a smaller bore of the facade insulation in the reinforcement. During subsequent mounting of the reinforcement, the cushion can spread on the building wall, as far as the facade insulation is there for space. Preferably

• -size the hole in the facade insulation provided for the spacer by as much as the outside diameter of the reinforcement
• and the pillow volume is sized so large

that a desired footing takes place at the reinforcement through the cushion. Preferably, a spread is also about 20 to 40mm into consideration. With a diameter of the reinforcement of 60 mm, this results in a 20 to 40mm larger hole in the facade insulation and Gebäudewandseitig a foot of 80 to 100mm diameter at the reinforcement, which contributes significantly to the bending strength of the spacer construction.
At the periphery, the cushion as well as the circumference of the annular foam member or the annular mat is preferably adapted to the extent of the reinforcement. Preferably, the outer diameter of the annular pad is at most equal to the outer diameter of the reinforcement.
Preferably, a spacer is provided in the cushion which limits the maximum compression. The maximum compression may be 80% or 70% or 60% or 50%, based on the starting thickness. Preferably, the restriction is made by means of a spacer, for example a ring with a larger internal diameter inserted in the pad, than the passage opening in the pad, so that the ring surrounds the anchor in the assembled state of the pad. Optionally, the ring can form the cushion wall at the passage opening or surround the anchor at some distance.
The compression can also be done depending on the clamping pressure when bracing the reinforcement.

The cushions are optionally made of an air-permeable but adhesive-impermeable valve. As a rule, the adhesive is much more viscous than water or similar liquids. The cushions may therefore be permeable to water but non-permeable to adhesive.

There are various commercially available fabrics that hold up to the existing contact pressures suitable for pillows and therefore are suitable for the pillows.

The cushions and annular foaming parts and annular mat parts have advantages even at a small thickness as a leveling layer and / or connection to the reinforcement. Preferably, however, the thickness is at least 3 mm, more preferably at least 6 mm and most preferably at least 9 mm.

Also the cushion technique is for the solution after the PCT / EP2017 / 314 advantageous.

Optionally, the reinforcement consists of several parts, for example a (first) part which forms the contact surface with the building wall and a second part facing away from the building wall. It may be advantageous if the building wall-side part, which forms the contact surface with the building wall, sitting loose on the anchor without screwing and when the other (second) part is bolted to the anchor. Then the loose-fitting part can be glued easier and then the tension is done with the bolted second part.

Preferably, the building wall facing first part of the reinforcement of small thickness, for example, of a thickness less than or equal to 10mm, even more preferably of a thickness less than or equal to 7mm, most preferably of a thickness less than or equal to 4mm

In the above multi-part design of the reinforcement, it may be advantageous if the first part without screw sitting slidably on the anchor and when the second part engages with an edge in a recess of the first part or vice versa. Then, the first part of the reinforcement forms an oversized washer for the second part of the reinforcement screwed onto the armature. Shear forces and bending forces acting on the second part are transmitted directly to the first part and discharged into the building wall.

The reinforcement preferably partially fills the space between the head of the spacer and the building wall. If the filling is incomplete, the anchor protrudes from the reinforcement. When the distance between the head and the building wall is completely filled, the reinforcement gives the anchor more stability than when the distance between the head and the building wall is partially filled, when the reinforcement has the same cross-section. However, a partial filling of the distance between the building wall and the head may be more advantageous, which may be the case when the armature at the end, which protrudes on the building wall side facing away from the amplifier, has sufficient strength. Then, the reinforcement according to the invention can be used for different insulation layer thicknesses / facade thicknesses, without having to fill the gap between a head piece or the facade external spacer and the amplifier. That is, without the amplifier must extend exactly to the head of the Abstandshaalters or to the facade outer edge. The filling of the distance seems easy, but in practice is associated with some effort, because the head of the spacer to complete with the facade or the amplifier must complete with the facade exterior surface, if no head is provided. In case of inaccurate positioning, the amplifier overhangs the facade or the amplifier is located opposite the façade surface. The first one can be seen. The latter can interfere with the assembly of the parts to be fastened in front of the facade.

However, with the cantilevered end of the anchor, the head of the spacer can be positioned accurately at the desired location on the end of the anchor. The same applies if no head is provided and the parts to be mounted are to be attached directly to the projecting anchor end.
Alternatively, the assembly is supported with a nut, which is screwed on the projecting anchor end before mounting the head. The head of the spacer is then screwed against the nut and tightened. Alternatively, the head of the spacer is first screwed onto the protruding anchor end and then secured with a lock nut.

The projecting end of the anchor end and the distance of the spacer head from the reinforcement do not preclude that after the mounting of the spacer an open space is filled in the introduced for the spacer in the facade insulation bore. For this purpose, then usual insulation material or a building foam application. The construction foam is preferably a polyurethane foam.

The reinforcement is preferably designed as a hollow body with a larger diameter. This facilitates handling and saves material. The hollow body may be in one piece and in several parts. The hollow body can be made of the same material everywhere. Preferably, the hollow body consists of a plastic, even more preferably of a fiber-reinforced plastic. At the same time metallic surfaces are provided at the locations of the hollow body, where a screw with the anchor should take place. Preferably, metallic screw nuts are molded into the hollow body for screwing with the armature.

Each used as a reinforcement hollow body optionally consists of at least one outer sheath and at least one, preferably two lids, optionally also from an inner sheath.
Optionally, the parts associated with the hollow body are at least partially fixed or detachably connected to an outer shell. In an advantageous embodiment, a cover with the outer shell is firmly connected or even in one piece. Then it is spoken of a closed end of the coat. The other lid is detachably connected to the outer jacket As a detachable connection a screw is provided. In this case, the cover to be screwed may comprise the outer sheath as a cap or engage in the interior of the outer sheath. Depending on the screw is then found on the outer shell an external thread or an internal thread.

As far as the hollow body not only has an outer sheath, but also an inner sheath, a screw can also be done with the inner shell.
Optionally, then from the inner shell and the outer jacket, a coat with a cover and the other coat with the other cover firmly connected or even in one piece, so that the gain is only formed by two parts that can be screwed together. Of these two parts is optionally at least the part with the lid, which faces away from the building wall, bolted to the anchor. The other (building-side) lid can also be bolted to the anchor or sit loosely on the anchor in the embodiment described above and pressed by means of a nut or the screwable other part of the amplifier against the building wall.

• -ein kurzer Anker, der mit dem einen Ende der Verstärkung verspannt wird
• -einer Verstärkung mit geringerer Wärmeleitfähigkeit als bei dem Anker
• -einem Anschlußstück, welches an einem Ende mit der Verstärkung verspannt ist und an dem anderen Ende für die Verbindung mit einer Markise oder einem anderen Teil bestimmt ist, das vor der Fassade montiert werden soll.

A thermal separation between the building wall and provided for attachment to the facade parts is preferably in the reinforcement. Here, according to the older proposal of PCT / EP2017 / 314 intended;

• -A short anchor that is strained with one end of the reinforcement
• a reinforcement with lower thermal conductivity than the anchor
• - a connector which is braced at one end with the reinforcement and at the other end intended for connection to an awning or other part to be mounted in front of the facade.

For the reinforcement with lower thermal conductivity, various plastics are suitable. Preferably, a technical plastic is selected with a yield stress of at least 50 MPa, even more preferably with a yield stress of at least 75 MPa, and most preferably with a yield stress of at least 100 MPa. The selectable plastics include, for example, PA, PEEK, PES, PAI.

But also plastics with lower yield stress can be suitable as reinforcement according to the invention, if they are provided with a fiber reinforcement. Common fibers are glass fibers or fibers of higher yield stress plastics.

The reinforcement may be solid (except for necessary holes for anchor and fittings) and be provided at both ends with a blind hole having an internal thread. The thermal separation is done by using plastic for the amplifier. The plastic inhibits the flow of heat from the fitting to the anchor and vice versa. Preferably, high-strength plastic described above or a fiber-reinforced plastic is used.

A version with thermal separation provides a cylindrical body made of plastic, which is screwed into a hollow cylinder made of plastic. The cylindrical body is closed at the end facing away from the hollow cylinder. The hollow cylinder is closed at the end facing away from the cylindrical body. There are screw holes in both ends, so that the cylindrical body can be clamped to the building wall and the hollow cylinder can be clamped to the awning or another part which is to be mounted on the facade. Or vice versa, it is the hollow body with the building wall and the cylindrical body with the awning or the other to be mounted on the facade part clamped.
The tension with the building wall via the anchor, which expediently does not protrude much further from the borehole, as is required for the screw.
What is required to project, depends on the screw. Particularly inexpensive is a screw with a nut that projects through the bottom / lid of the building-side spacer member through, so that the nut can be screwed onto the protruding end and press the relevant spacer member against the building wall. The nut is preferably a hex nut. The associated wrench then has a hexagon socket.
It can also be provided more complex fittings. This is the case, for example, when the building-wall-side spacer part has on the anchor side a blind hole formed as a threaded hole.
Then, a handle surface for a wrench is preferably provided on the blind hole opposite surface of the spacer member. For bracing the building wall-side spacer member then a handle surface for a wrench is then formed, for example, in the surface centric. Alternatively, a grip surface for a wrench is formed on the surface.
The molded surface can be a hexagon or square. Similarly, the molded surface may be a hexagon or a square. There are also handle surfaces into consideration, in particular surfaces according to:

• Torx, internal spline, external spline, Pentalob, Bristol

The wrench is adapted to the grip surface on the spacer part, for example in the case
the Torx outer surface has a Torx inner surface on the wrench
the inner multi-tooth surface an outer multi-tooth surface on the wrench
The Pentalob outer surface of a Pentalob inner surface on the wrench
the Bristol outer surface is a Bristol inner surface

The details of the handle surfaces described are listed for example in Wikipedia under the term "screw".
It may also be reversed by providing on the or in the spacer portion, the surface which is intended above the wrench. Then, the wrench has the surface provided above in the spacer member and the spacer member the surface provided above on the wrench.
Wrenches are moved by hand. Better are electrical or pneumatically operated screwdrivers with corresponding grip surfaces or tips. Preferably, screwdrivers are brought with adjustable torque for application, so that a tearing of the anchor from the building wall is excluded by an excessive torque when screwing.

It can also be incorporated centrally in the building-wall-side spacer member a Phillips, in which engages a screwdriver with a corresponding tip.

The second spacer member is screwed in the described embodiment, after tightening the first spacer member on this or in this. This can be done by hand, as long as it can be screwed without significant torque.
The subsequent bracing with the awning or the other, to be mounted in front of the facade part is preferably carried out via a threaded rod piece as a connector / connector which engages in a corresponding opening of the second spacer member or is already pre-assembled in the second spacer member, optionally molded. For this threaded rod piece then a threaded hole is optionally provided in the second spacer member. The threaded hole can be formed as in the case of the first spacer member by the spacer member or by a molded nut. The screwed into the threaded hole threaded rod is preferably secured by a lock nut.
The lock nut may also be advantageous for a second spacer member with pre-threaded threaded rod piece.

Another embodiment of thermal separation also provides a two-part spacer. In this case, the Gebäudewandseitige spacer member is formed by a circular disc which is externally threaded. With the disc acts a spacer member together, which is designed as a hollow cylinder and is provided with an internal thread for screwing to the disc.
The disc is centric with a molded thread or with a molded nut, with which it can be bolted to an anchor and braced against the building wall. The disc can also sit loosely on the anchor and be clamped with a nut against the building wall.

Instead of the central armature, it is also possible to provide a plurality of smaller armatures at a distance from the center of the pane. In that case, through holes are provided for the various anchors in the disk. At the same time, instead of one borehole for the central armature, correspondingly many boreholes are provided for the armatures spaced apart from the center of the pane in the building wall. These anchors may have a thread for screwing to a nut on the end protruding through the disc. The anchors can also be screws, in particular head screws, which are set by hand or with a screwdriver.
The hollow cylinder is formed like the hollow cylinder described in the above embodiment. He has a closed end with a molded thread or a molded nut. The closed end may also have a molded threaded rod piece or a through-hole for the threaded rod piece, the threaded rod piece being held in the closed end by nuts.
The threaded rod piece serves to connect to the part to be mounted in front of the facade, for example an awning.

In all applications, instead of the seated in a through hole threaded rod and a bolt can be used. The bolt is then optionally provided only at both projecting ends with a thread, so that at each end a nut can be screwed to its attachment to the bolt. Preferably, the bolt is also provided with a collar, so that a nut for
Attachment / clamping of the bolt in the closed hollow cylinder end sufficient. This results in the clamping of the closed hollow cylinder end between the nut and the collar of the threaded rod piece. Even more preferably, the bolt is stepped in diameter or provided with a shoulder. The heel acts as a step and allows the bracing of the closed threaded rod piece with a nut.
Instead of the threaded rod piece head screws can be used, which extend through the closed end of the hollow cylinder and form the connection for the parts to be fastened in front of the facade.

Another advantageous embodiment with thermal separation provides a solid cylindrical body made of plastic, in particular fiber-reinforced plastic, which can be screwed into a hollow cylinder. The screw-in cylindrical body has an outer collar and is preferably arranged Gebäudewandseitig. The cylindrical hollow body has an inner collar with a central opening, which forms a threaded bore. It can also form a formed in the cylindrical hollow body nut made of steel threaded hole. All of the nuts and threaded rods mentioned here are preferably made of steel.

In the threaded bore a threaded rod piece is preferably screwed as a connector for outside on the facade to be fastened parts such as awnings.
At the outer collar, the tension takes place with the building wall. For this purpose, for example, uniformly distributed holes are provided in the collar, the holes in the collar correspond with holes in the building wall, so that the tension can take place with anchoring through the holes in the collar.

The wall thickness of the cylindrical hollow body is so large that an overlap of the outer collar takes place on the screw-in body and in the shell of the cylindrical hollow body bores can be introduced, which are aligned in a corresponding rotational position with the holes in the outer collar. If the anchors are introduced by the aligned holes in the cylindrical hollow body and the outer collar in the holes in the building wall, so is not only the desired tension of the spacer to the building wall, but also the locking of the cylindrical hollow body on the screw-cylindrical body instead.
The anchors can be formed by an expansion dowel and suitable screws which are screwed into the expansion dowel and thereby cause a strain in the boreholes.
Alternatively, the anchors are additionally glued in the boreholes. This can be done with adhesive cartridges that are pressed into the drilled holes. Or glue can be pressed into the wellbore with a hand press in the form described above.

The hollow bodies described above are also suitable for thermal separation. Preferably, two nested parts are provided, which consist of lids and outer shells. Each cover has an outer jacket. The one outer shell has an external thread and a smaller diameter than the other outer shell, which in turn is provided with an internal thread.
From this amplifier, the Gebäudewandseitige (first) part is first mounted and then the other (second) part with the already mounted (first) part screwed. In the other (second) part of the connecting piece / threaded piece for the connection with an awning to be fixed in front of the facade, etc. already pre-assembled.

The fitting is preferably a threaded rod piece. The threaded rod piece can be screwed in the same way with the amplifier as the anchor. At the same time, the threaded rod piece is very advantageous for the connection with awnings and other parts that are to be mounted on the outside of the facade.
Preferably, the threaded rod piece has a diameter that is at least equal to the diameter of the anchor. This allows in the manner described above, a protruding of the connecting piece. When advanced, the fitting in the protruding part is not supported by the reinforcement. The advantages of the advance are described above.

The degree of Vorkragens can be further increased if a diameter is selected for the connecting piece forming the threaded rod, which is greater than the armature diameter of the armature.
This refers to the application of a centrally arranged anchor.

Instead of the central armature, it is also possible to use a plurality of armatures which are arranged at a distance from the center of the spacer. This is also in the context of the older proposal after the PCT / EP2017 / 314 , The distances to the center of the spacer may be the same or different. The anchors can lie on a circle or on the corners or lines of geometric figures.

The use of multiple anchors allows the use of anchors with a smaller anchor diameter than a single centrically arranged anchor.

In the case of the above-mentioned use of a plurality of eccentrically arranged armatures, a cross section is provided for the threaded rod which forms the connector, the cross-sectional area of which is at least equal to the buzzer of the cross-sectional areas of all anchors (engaging in boreholes). Preferably, the cross-sectional area of the threaded rod forming the fitting is at least 1.3 times, more preferably at least 1.5 times, and most preferably at least 1.7 times the sum of the cross-sectional areas of all eccentrically arranged anchors.
With the multitude of eccentrically arranged anchors for connection to the building wall, on the other hand, there is the possibility of reducing the cross-section for each of the anchors. The reduction can go so far that commercially available screws are suitable as anchors, also together with an expansion dowel. Preferably then find screws with a diameter of greater than or equal to 5mm use, even more preferably with a diameter of greater than or equal to 6mm. The length of the screws is according to the invention in relation to their diameter. Preferably, the length is at least 10 times the diameter, more preferably at least 15 times the diameter, and most preferably at least 20 times the diameter.
Among such screws, the countersunk screws are particularly common, even in different qualities up to screws made of rust-resistant material or rust-inhibiting coating. Of the countersunk screws most have a Kreutzschlitz, so that for setting the screws Kreutschlitzschraubendreher or a screwdriver with a Kreutschlitzspitze is required. If necessary, the screwdrivers and screwdrivers are to be provided with an extension. A necessary extension on a Schreubendreher or screwdriver can be done by separating the screwdriver between the tip and handle or by separating between screwdriver tip and tool holder in a screwdriver and by welding an intermediate piece.

Countersunk screws have a conical head. The opening in the spacer for the screw head must be correspondingly conical. This can cause problems with inaccurate holes in the building wall. However, the accuracy of the drilling can be significantly increased with the help of drilling templates and with the help of drill stands, which are placed on the building wall and lead the drill while drilling.

As a centric anchor can be used in thermally separated spacers and a screw instead of a threaded rod for clamping with the building wall. Sufficiently thick and long screws with metric thread and hexagon head are partially available.
As far as such screws are not available, such screws can be made of a threaded rod and a hexagonal profile. From the threaded rod the appropriate lengths for each hole are sawed off. For the screw heads corresponding pieces are sawn from the hexagonal profile. Subsequently, the threaded rod parts and sawed off from the hexagonal pieces pieces can be welded together.
The metric thread provides the screws with their adhesion sufficient support in the borehole. With the simultaneous use of an expansion anchor, it may be appropriate to produce holes with a slightly larger diameter to account for the fact that the Aufspreizvorgang with a screw with a metric thread is different from the spreading of expansion dowels with dedicated screws that have a long tip and whose threads have a much greater pitch than a metric thread.

In the drawing, an embodiment of the older spacer in 1 to 32 shown. The 33 to 43 show the application of the older proposal on prior art spacers.

1 shows a building wall 1 with a thermal insulation 2 ,
Before the insulation 2 If an unillustrated canopy to be mounted. For this purpose, a fixture for the canopy by the thermal insulation 2 made of rigid foam can be anchored in the building wall.
For anchoring, use a hammer drill 4 and a drill 3 holes 5 at a predetermined location by the thermal insulation 3 through the building wall 1 drilled.

To 2 The next step will be a crown drill 10 used.
This is done with the crown drill 1 in the thermal insulation 2 resulting hole to the building wall 1 drilled. It takes the crown drill 10 the cut-out parts of the insulation in itself. The crown drill 10 has a sleeve whose open front end is formed as a cutting edge. The sleeve 10 is held on a rod, which at one end in the chuck of the hammer drill 4 sits and engages in the borehole at the other end and forms a guide.

3 shows the crown drill 10 in a single view.
Here is the sleeve 10 provided with markings which make it easier for the installer to maintain a drilling depth which is the same as the thickness of the thermal insulation, but does not go beyond that.

The hammer drill 4 is for drilling the hole in the insulation 2 adjustable to sole drilling without simultaneous hammering.

4 shows the next step, in which a cleaning of the borehole 5 he follows. This is done via a probe 16 with an air pump 15 , With the air pump 15 is over the probe 16 Air in the hole 5 blown.

5 becomes the borehole 5 filled with a two-component adhesive. The two-component adhesive is taken from a cartridge with a standard hand press into the hole 5 pressed.

To 6 is after filling the two-component adhesive in the hole 5 a threaded rod 25 used. To insert finds 7 a guide rod 27 Application. With the guide rod 27 can the threaded rod 25 be detected at the end. This happens before the onset of Threaded rod in the borehole 5 , In this case, a screwing take place. This is in the guide rod 27 provided a corresponding threaded hole. Sufficient but can also be a hole without internal thread, in which the threaded rod 25 with their end finds sufficient support.
The threaded rod 25 is guided during insertion at one end in the borehole.
To guide a cone can be mounted on the guide rod.
With the cone, the guide rod is centered in the borehole of the thermal insulation. After properly setting the cone on the guide rod, the cone prevents the threaded rod from being pushed too deep into the drill hole.

The guide will remain in place until the glue has solidified in the hole. Then the guide rod 27 from the threaded rod 25 unscrewed or removed.

In other embodiments, other threaded rods are provided with larger diameter for larger loads.

Depending on the amount of adhesive occurs when penetrating the threaded rod 25 in the glue partially with glue from the well, which contaminates the contact surface of the spacer on the building wall. In addition, the contact surface may be uneven.
Therefore, a leveling of this contact surface is after 8th intended. This is done with the help of a face milling cutter 35 , The endmill 35 has an in 9 illustrated cylindrical shape, wherein the end face 34 is provided with appropriate cutting. Besides, the face cutter has 35 centric in the face a hole 37 with a diameter that allows the end mill 35 over the protruding end of the threaded rod from the borehole 25 to push. The endmill 35 owns a pin 38 which is in the chuck of the hammer drill 4 sitting. The hammer drill 4 will switch back to sole drilling for this work.

The endmill 35 persists 10 and 11 from a holder 36 and a replaceable cutting insert 39 , The illustrated insert is for a threaded rod M12 certainly. To be pushed over the threaded rod, the insert has a central hole with a diameter of 13mm. For inserts for other threaded rods, hole diameters of 17mm, 21mm, 28mm, 28mm, 31mm may be appropriate.

After processing the contact surface on the building wall is a building-side Abstandshalterteil 40 in the form of a pin with a building-side collar on the end of the threaded rod 25 screwed, which protrudes from the borehole. The screwing process continues until the spacer member 40 with the collar comes to milled surface of the building wall to the plant. A slight further rotational movement leads to a strain of the spacer part 40 on the building wall.

For screwing is in the spacer part 40 a continuous cylindrical and extending in the longitudinal direction opening provided.
At the building end of the opening protrudes an edge / collar with an inner diameter that is larger than the outer diameter of the threaded rod 25 is, so that the spacer part 40 on the protruding end of the threaded rod from the hole 25 unscrew until an insert in the opening of the spacer part 40 on the protruding end of the threaded rod 25 encounters. That happens after 12 with a socket 41 , The socket wrench 41 is turned with a ratchet. This happens gradually, because the ratchet is moved back and forth. By turning the socket wrench 41 the insert is turned and onto the protruding end of the threaded rod 25 screwed until the spacer part 40 is clamped to the building wall.

The insert opening 42 for the socket wrench is in 13 shown.
The opening width is greater than the diameter of the associated threaded rod, so that the socket wrench does not hinder the screwing of the spacer member on the threaded rod.

The spacer part 40 has an external thread.
With the spacer part 40 corresponds to another spacer part 50 in the form of a tube closed to the outside of the thermal insulation, which is connected to the spacer part 40 forms an adjustable spacer. For this sits the spacer part 50 with an internal thread on the spacer part 50 , The thread is a fine thread.
By changing the screw position creates an extension or shortening of the spacer.
For screwing has the spacer part 50 also an opening / seat for the socket wrench 41 ,

In addition, the spacer part can 40 be combined with other longer or shorter spacer parts. The longer or shorter spacer members differ in the embodiment of the spacer member 50 through longer or shorter tubes.

The spacer is set in the embodiments so that its head flush with the heat insulation and the threaded rod or a threaded rod piece protrudes.

The 19 and 20 show two spacers according to the invention, in which the cavity for thermal insulation with soft plastic foam 62 respectively. 63 is filled.

As far as beyond a cap 60 with a central opening for the threaded stem 51 Applicable, the spacer is adjusted so that the seated on the head of the spacer cap 60 flush with the thermal insulation. In this case, an edge is provided with a seal on the cap, with which the thermal insulation is overlapped. The situation is in 21 shown; the cap in 22 ,

The spacer member has a threaded pin on the head 51 ,

23 shows in a further embodiment of the invention, a building wall 70 with a pre-installed thermal insulation 72 , For awning attachment before the thermal insulation 72 is a hole 71 through the thermal insulation 72 through the building wall 70 been introduced. In the hole 71 is a threaded rod 73 bonded. The threaded rod 73 extends far into the thermal insulation 72 but ends before the outside of the insulation 72 ,
The hole 71 is in the heat insulation to the measure 77 been drilled out. In the resulting larger bore is a tapered reinforcement 74 screwed from a high-strength plastic. The reinforcement has this 74 a longitudinally continuous threaded hole. The reinforcement 74 has a building-wall-side diameter of about 5 times the diameter of the threaded rod 73 is. The reinforcement 74 tapers towards the outside of the insulation. The reinforcement 74 is by turning on the threaded rod 73 been braced against the building wall surface.
At the end of the threaded rod 73 sits a molding 75 made of high-strength plastic on the threaded rod 73 , The associated threaded hole in the molding 75 is formed as a blind hole, so that the molded part 75 with tension on the threaded rod end can be screwed.
The molding 75 serves the thermal decoupling of the threaded rod. This is a head piece 76 have been separated from the threaded rod and screwed in a likewise formed as a blind hole threaded hole, the previously described blind hole in the molding 75 exactly opposite.
The outside of the insulation shown plate 78 is a facade panel, which is used to introduce the hole 77 and the conical reinforcement has been removed and brought back to the original place after the final assembly of the spacer before the housing of the awning, not shown on the head 76 the threaded rod is attached.

24 shows two further embodiments of the invention one above the other on a building wall 80 and with a thermal insulation 81 , The upper embodiment has a continuous threaded rod 82 standing in a hole in the building wall 80 is glued in and out through the thermal insulation 81 extends and on the outside opposite the thermal insulation 81 projects. The hole for gluing the threaded rod 82 is as in the embodiment 23 through the thermal insulation 81 through the building wall 80 has been brought. Then the hole has been drilled out. Then there is a reinforcement 83 on the threaded rod 81 and against the building wall 81 screwed. This differs from the embodiment according to 23 by a cylindrical shape of the reinforcement 83 , Besides that, they are different than after 23 more cylindrical body on the threaded rod 82 screwed. Here is the outside cylindrical body 83 with the reinforcement 83 identical. The other cylindrical body 84 . 85 and 89 form intermediate pieces between the reinforcement 83 and the outside body 83 , All additional cylindrical body are braced against each other and against the reinforcement, glued together in another embodiment. This increases the reinforcement of the threaded rod.
The outside protruding end of the threaded rod 82 used in the embodiment of the attachment of an outside lying on the building escalator.
The spacers and the outside cylindrical body allow adaptation to the thickness of the existing thermal insulation. This is done by replacing other cylindrical bodies. In the exchange, the cylindrical body of the building-wall reinforcement can be included. When changing the total thickness of all cylindrical body and the length of the threaded rod can be changed by replacement. That means, it does not have to be a too short or too long threaded rod mounted and then replaced. Rather, a threaded rod is selected immediately with a length that still projects for the desired total thickness of all cylindrical body sufficient for the attachment of the functional part measure against the thermal insulation.

The lower embodiment of 24 differs from the embodiment by a three-piece threaded rod consisting of pieces 87 . 90 and 91 put together. Between the different pieces are provided for the thermal end coupling. There is another cylindrical reinforcement for this purpose 88 and a structurally identical cylindrical body 88 outside application. The reinforcement 88 owns like the part 75 to 23 two threaded blind holes. The same applies to the external body 88 in 24 , The building wall reinforcement 88 is with the out of the building wall 80 protruding end of the threaded rod 87 firmly screwed. In addition, the threaded rod 90 firmly in the associated threaded blind hole of the building wall amplifier 88 screwed. On the threaded rod 90 are the cylindrical spacers 86 screwed or glued in the same manner as the intermediate pieces of the embodiment shown above. The one to the amplifier 88 identical, externally arranged cylindrical body 88 Corresponds with the threaded rod accordingly 90 and the threaded rod 91 , Also the construction after 24 causes an increase in the reinforcement for the threaded rod. In addition, the construction allows 24 an adjustment of the total thickness to the thickness of the existing thermal insulation. The same applies to the threaded rod. This can be the replacement of a part or two parts of 24 restrict three-part threaded rod provided.

To 25 is in a further embodiment of the invention on the same building wall 80 the same part 87 glued to a threaded rod. On the threaded rod / threaded rod piece 87 is however a pipe 95 attached, the building wall side a closed end 96 having. The end 96 is with a nut 99 against the building wall 80 curious; excited. The pipe 95 is open at the opposite end with an internal thread, so that a second tube 97 in the open end of the pipe 95 can be screwed. The second tube 97 has a correspondingly smaller outer diameter than the first tube 95 and for the screw externally an external thread. In that area 101 overlap pipes 95 and 97 , The pipe 97 is open on the building side. The other end 100 is closed. In the end 100 is a threaded rod piece 91 attached, the threaded rod piece 91 to 24 equivalent. The threaded rod piece 91 to 25 sits in a threaded hole of the closed end 100 and is secured with a nut. The pipe 97 can in the pipe 95 further screwed in or out of the pipe 95 partially screwed back again. This will change the length of the tube through both 95 and 97 formed spacer. The change in length serves to adapt to the thickness of the respective thermal insulation.
So that the trapped air within the tubes does not make the change in length difficult, are in the closed end 100 two ventilation holes provided.
In the selected length of each tube can be screwed into each other by the tension of the tube 95 be held on the building wall and by the connection with the functional part, not shown in the selected Schraubstellung. This results in a rotationally fixed arrangement of the functional parts already by a simultaneous connection with another spacer. Unless a sufficient rotationally fixed connection is mediated by the functional part or a backup of the screw is desired before attaching the functional parts, is a blockage of the thread or the pipe 97 intended. This can be achieved in a simple form with an adhesive or by pins or the like, which in the area 101 be driven through openings in both tubes.
The construction after 25 allows the production of a spacer with less material but the same load capacity as in a training after 23 or 24 or with the same material use with higher load capacity than in a training after 23 and 24 ,

In a further embodiment, not shown, instead of the tube 95 a cylindrical body provided as a building wall-side amplifier, which is like the pipe 95 with a threaded rod piece 95 is kept in the building wall. This cylindrical body is externally threaded so that an internally threaded tube can be screwed onto the cylindrical body. The screw-on tube has the same features as the tube with respect to the closed end and a threaded rod piece seated in the closed end 97 in 25 ,

In another embodiment, a pin is provided instead of the above-described cylindrical externally threaded body. The pin also has a cylindrical body. However, this body is provided on the building wall side with a collar. In 26 is a series of three
Spigot shown. The length of the pins 105.1 . 105.2 and 105.3 is different. The thickness of the collar 106.1 . 106.2 and 106.3 is different. The diameters are the collar and the cylindrical body is equal. Likewise, all pins have a through hole with an internal thread. At the end, which faces away from the collar, the pins are with a hexagon 108 Mistake. The hexagon is used to mount the pin. The pin on the hexagon 108 detected with a tube whose front opening is modeled on the hexagon. With the tube, the pin is rotated / screwed on the threaded rod until it rests against the building wall. Another slight turning then causes a tension of the pin on the building wall.

During turning / screwing, the tube moves a short distance over the threaded rod.
The longer the pins are, the greater the support effect for the associated threaded rods.
Preferably, the pins are provided for M12 threaded rods or corresponding anchors with the following lengths and collar thickness according to the thicknesses of occurring thermal insulation Length in mm : 55, 70 90, 110 130 150 170 190 210 Collar thickness in mm: 8th, 10 10 10 15 30 30 40 40

Furthermore, up to a tenon length of 90 mm, the lateral surface of the pin approximately at right angles in the collar over.
For larger spigot lengths so large bending loads can result in the pin that a rounding with a large radius as a transition and / or an oblique transition from the lateral surface of the pin in the collar is beneficial.

The pins do not only have to cooperate with pipes which have a closed end as the embodiment according to 25 having threaded rod piece seated therein.
The pins can also interact with open, internally threaded tubes, which are screwed like closed tubes on the pins. Such tubes may have different lengths.
For M12 threaded rods or corresponding anchors, the following tube lengths are preferably assigned to the journal lengths: Spigot length in mm: 55, 70 90, 110 130 150 170 190 210 Pipe length in mm: 75, 85 105 120 120 120 120 120 120 Other lengths may result for other threaded rods.

In 27 are pipes 110.1 . 110.2 . 110.3 shown with tube lengths of 75, 85, 105mm. All tubes are provided in the embodiment throughout with an internal thread.
By different screwing or screwing back as in the embodiment according to 25 an adaptation of the spacer length to the thickness of the thermal insulation done.

To a similar solution as with the outside pipe after 25 to create, the pipes are after 28 closed on the outside with other pins. The other cones are made up of a cylindrical body 115 with external teeth and a collar 116 together. The length of the pin is the same for all spacers in the embodiment. In other embodiments, the length may vary.
In the pin is located in the middle of a blind hole 119 with internal thread for a threaded rod piece. In addition, a recess in the pin collar side 118 The recess can be described as an annular groove whose inner wall regularly distributed on six surfaces to a hexagon 117 has been flattened. Unlike the building wall-side pin with the attached hexagon 108 is a same hexagon 117 in the face of the pin 28 sunk. The hexagon 117 can be with the same tool as the hexagon 108 grasp and screw / turn into the pipe end.
Subsequently, as in the embodiment after 25 a threaded rod piece used, in the blind hole 119 for connection to the functional part to be fastened.

In a further embodiment, not shown, the invention is to AnkerAnwendung, which have been passed through the building wall and building inside are held with a Auf-Putz-Teller or a Unterputzteller. Such anchors can be clamped and / or glued in the same way as the anchor and threaded rods described above. The anchors then protrude either to the building wall in the insulation or until the insulation. The reinforcement according to the invention can then take place in the same way as in the embodiments described above.

The 33 to 35 show a building wall 201 with a insulated facade 206 ,

In front of the facade 206 an awning should be attached. For each of the awnings, a plurality of spacers is provided. Below, only one of the drill holes is considered. In this case, another, aligned borehole is provided in the heat insulation in addition to the hole in the building wall. In the case of a centric borehole in the building wall, it is advantageous first to produce the borehole in the building wall and thereby to drill it through the thermal insulation. Subsequently, the hole can be drilled in the heat insulation with a pot drill and the pot drill are doing with a rod in the hole of the building wall. In all embodiments according to 33 to 35 is in the borehole an anchor in the form of a threaded rod 202 glued as a spacer. The threaded rod 202 protrudes from the borehole to the top of the facade 206 , The freely projecting anchor end is used to connect the awning. To stiffen the protruding from the borehole threaded rod is after 33 and 34 an amplifier 203 on the threaded rod 202 intended. The amplifier leaves some distance from the outside of the facade. This results in a cavity which is filled in a manner not shown with insulating material. This serves to displace air from the cavity and improve insulation.

The amplifier 203 consists in the embodiment of a fiber-reinforced plastic part with a central bore with internal thread, so that the amplifier 203 on the threaded rod 202 screwed on and against the building wall 201 can be stretched.
In another embodiment is also between the amplifier 203 and the building wall 201 Glue provided so that the on the amplifier 203 acting forces directly into the building wall 201 be directed.

The embodiment according to 34 differs from the embodiment according to 33 in that the amplifier 203 by a measure of 10mm in the building wall 201 has been admitted. This is a corresponding depression with a router in the building wall 201 been incorporated.
In other embodiments, the dimension of the recess is 5 to 30 mm.

The embodiment according to 35 differs from the embodiment of FIG. By a two-part amplifier with parts 204 and 205 , The part 204 sits as a metal disc of 5mm thickness without internal thread on the anchor 202 , The part 204 forms an oversized washer for the part 205 made of the same material as the amplifier 203 , The part 204 is glued to the building wall and forms a full-surface support for the part 205 ,
In another embodiment, the part becomes 204 formed by a cushion which is filled with a solidifying mass. The part 205 In the exemplary embodiment, the cushion is initially at low pressure 204 and tensioned the building wall and tightened after solidification of the pillow filling until the desired voltage is reached.
In still other embodiments, the pad is filled with a pressure-hardening material.

The embodiment according to 36 is different from that 33 in that on the protruding anchor end a head 210 screwed, which concludes with the facade surface. In addition, an armature is made of parts for thermal separation 202a and 202b used. The parts 202a and 202b meet in the head 210 , Both have part 202a and 202b a distance from each other. To prevent contact between both parts 202a and 202b are in the head 210 provided two blind holes, which are opposite each other. The head 210 closes with the facade surface.

The embodiment according to 37 differs from the embodiments according to 33 to 36 by a spacer, which also has an anchor which is glued in a bore of the building wall. But there is a sleeve on the anchor 215 with a lid 216 against the building wall 201 is tense. While the sleeve 215 sitting loosely on the anchor with a through hole is the lid 216 screwed on the anchor end. The screwing and clamping cause a reinforcement of the spacer.
The lid 216 closes with the facade surface.

The embodiment according to 40 also has an anchor 202 , which is glued into a hole in the building wall and up to the thermal insulation 206 protrudes. The embodiment according to 40 differs from the spacer 37 in that Gebäudewandseitig a disc 225 is provided by means of a nut 226 on the anchor rod 202 bolted and stretched against the building wall. Instead of the sleeve 215 is a sleeve 228 intended. Also this sleeve 228 comes with a lid 227 braced; This time not directly against the building wall but indirectly over the pane 225 against the building wall. The sleeve 228 and the lid 227 are integral in the embodiment. To tension is the lid 227 provided with a central threaded hole, which is the external thread of the anchor 201 is adapted.
In another embodiment, a lid separate from the sleeve is provided. Sleeve is clamped between the disc and the lid, which is like the lid 227 can be screwed onto the threaded rod. The disc and the lid have projections with which the lid and the disc engage centering in the sleeve.

The embodiment according to 38 differs from the embodiment according to 35 through a head sitting on the anchor like him in 36 is shown and described. Besides, one is out of parts 202a and 202b existing anchor as in 36 intended.

The embodiment according to 39 differs from the embodiment according to 38 through an amplifier 203 with a tip 221 instead of the disc 206 , For the top 221 the bore in the building wall has been correspondingly widened conically. The advantages of conical expansion are centering of the spacer and easier positioning of an adhesive to bond the tip 221 ,

The embodiment according to 41 differs from the other embodiments by a thermal separation. At the thermal
Separation, the heat flow is interrupted by the parts to be fastened on the facade via the anchor into the building wall. This happens because instead of the long anchor 202 (which protrudes to the front) a short anchor 235 is used, which ends at a distance in front of the facade outside. Otherwise, the anchor is in the same way as the anchor 202 held in the building wall, so in the borehole with a bond or with an expansion dowel or with an expansion dowel and a bond.
In the embodiment, the anchor 235 like the anchor 202 formed by a threaded rod piece.
In the exemplary embodiment, the anchor protrudes 235 so far out of the building wall, that a cylindrical spacer portion on the projecting end of the armature 235 can be screwed. This spacer part has a threaded piece 237 with external thread, on which another spacer part 240 can be screwed with an internal thread.
For the two spacer parts is a hole 236 in the facade 206 been introduced to the building wall.
These two spacer parts are made of reinforced plastic with a low thermal conductivity in relation to the steel of the anchor 235 , Building wall side is the spacer part with a flange / collar 238 Mistake. The flange / collar / collar 238 increases the bearing surface of the spacer part on the building wall. The size of the bearing surface / contact surface on the building wall has a significant influence on the stability of the spacer.
Between the spacer part and the building wall is a cushion filled with an adhesive 239 provided, which solidifies and thereby forms an advantageous bearing surface for the spacer member. As glue For example, a material with a high early strength can be used, in which the assembly does not have to be interrupted. The cost of the adhesive are of minor importance, if, for example, only an awning with a few attachment points to assemble.

In other embodiments, contact surfaces on the building wall 201 and the flange / collar 238 cleaned, for example, with compressed air. Subsequently, adhesive is applied directly to the contact surface of the building wall 201 and / or on the flange / collar / collar 238 applied, so that there is also a bonding of the flange / collar / collar 238 comes at the building wall. Advantageously, improves the static of the construction with the bond. It increases the load capacity of the spacer.

In still other embodiments, instead of the pillow 239 provided a piece of compressible mat impregnated / filled with the adhesive. The thickness of the mat can be low, because building walls are usually flat. Plan less Building space can be accommodated by using two or more mats.
As far as in the adhesive part of the gap between the building wall and the spacer emerges, it is harmless, because the adhesive then remains invisible between the insulation and the building wall. Incidentally, the expert can dose the amount of adhesive with little exercise so that only a little glue or no glue comes out of the gap. This is helpful when the flange / collar / collar 238 provided with a rubber cuff or other resilient material. The cuff includes the flange / collar / collar 238 and expands as the glue pushes out, but keeps the glue from flowing uncontrollably into the insulation of the facade.

When mounting the spacer part with the thread 237 and the flange / collar / collar 238 can the desired tension of the spacer part on the anchor 235 and be reached against the building wall by means of a wrench attached to a hexagon 242 engages which is integrally formed on the spacer member. As a wrench, a ratchet is preferably used, which engages with a so-called nut on the hexagon. Between nut and ratchet an extension piece is optionally provided. The ratchet makes it possible to move the wrench back and forth and yet rotate the spacer member only in one direction.

After assembly of the building-side spacer becomes the spacer part 240 screwed. The spacer part 240 Like the building-side spacer, it consists of a fiber-reinforced plastic.

In the embodiment, the spacer member closes 240 with the facade top off. In other embodiments, the spacer member may be recessed or protruded from the facade top. The spacer part 240 is at the closed end with a pin in the form of a threaded rod piece 241 Mistake. At the threaded rod piece attachment of the awning takes place.

The embodiment according to 42 and 43 is different from that 41 by six anchors evenly distributed on a circle 250 instead of a centrally arranged anchor 235 , For the six anchors 250 There are six matching holes in the building wall. The six anchors 250 together have a cross-sectional area smaller than the cross-sectional area of the centric anchor 235 is. Static, however, does not involve a disadvantage. Every single one of the anchors 250 becomes much less than the centric anchor 235 loaded. Due to the smaller cross-sectional areas conventional expansion dowels and associated screws with countersunk head could be used.
For the six anchors 250 are in the flange / collar / collar 251 provided the building wall spacer member through holes. In addition, there are holes for the six anchors in the wall of the other spacer member 250 , These holes have over 2/3 of the length of the wall a diameter large enough to accommodate the countersunk head of the screws. Over the remaining length of the wall, the holes are so large that the anchor 250 can be pushed through with sufficient play.

By placing the anchors both through the wall of the spacer holder part 253 as well as through the flange / collar / collar of the building wall spacer member grab, is the spacer member 253 locked in its rotational position. The locking takes place only when the spacer by screwing / rotating the spacer part 253 on the other spacer member has reached the desired position in which he flush with the facade top or stands back or protruding.
For connection to an awning to be fixed in front of the facade has the spacer part 253 the same pin as the spacer part 240 to 41 ,

In other embodiments, they are anchors 250 bonded screws simultaneously bonded with the expansion dowel in the boreholes.

In still other embodiments, the six anchors are prior to screwing the other spacer member 253 with flange / collar / collar 251 braced against the building wall. The holes in the wall of the spacer part 253 are then dispensable.

The locking of the spacer member then takes place, for example, in the connection with the part to be fastened to the facade.

In another embodiment of the invention, both spacer parts which can be screwed into one another or onto one another are provided with a flange / collar / collar. The flange / collar / collar of the building wall spacer member is then compared to the embodiment according to 42 and 43 twice as big. The additionally provided on the other spacer member flange / collar / collar is then as large as the after 42 and 43 provided collar. Then, in the additional flange / collar / collar of the other spacer member, six holes / through holes are evenly distributed on a circle of larger radius.
The holes / through-holes provided in the flange / collar / collar of the building-wall-side spacer part are uniformly distributed on a same circle. Also, the holes / holes in the building wall are evenly distributed on the same circle.
With this embodiment, the same locking of the spacer parts can be as after 42 and 43 reach without long holes must be introduced into a sleeve wall.
