Definitions
- 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.
- Threaded rods anchored as spacers whose length is such that they protrude in front of the building through the thermal insulation and also protrude beyond the heat insulation, which is required for the attachment of the parts to be fastened in front of the facade.
- the threaded rods are mostly Ml 2 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.
- 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
- 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.
- the object of the invention has been found to facilitate a defect-free attachment of the parts.
- 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 heat insulation on the measure according to the invention.
- 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 one
- 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.
- the tool for making the larger bore in the insulation is, for example, a light one
- the stone drill can be mounted on the stone drill bit.
- the larger hole in the thermal insulation is used according to the invention to screw after bonding the threaded rod in the building a reinforcement on the threaded rod and to clamp against the building wall.
- the ability of the threaded rod is used to absorb much more tensile load than Beigelast.
- the reinforcement may be an annular thickening with a corresponding bearing surface on the building wall.
- the diameter of the reinforcement is equal to the inner diameter of the bore in the
- 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 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.
- adhesive that swells out of this when penetrating the anchor in the borehole can remain so within limits. In limits, too much glue must be removed, while removing the excessive
- the amount of adhesive need not be applied with care on the surface enclosed by the above-mentioned annular contact surface.
- Threaded rod on the building wall can also be a bonding of the
- 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.
- 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.
- 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.
- 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.
- the clamping force can be transmitted to the reinforcement with a nut without the risk of entrainment of the reinforcement.
- 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.
- 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, which is also used for gluing the
- a suitable adhesive is, for example, a gel-type, solvent-free two-component adhesive based on
- Epoxy resin with a cycloaliphatic polyamine hardener is for example, under the name Akepox 5010 commercially available.
- the advantage is a minimal shrinkage during curing of the adhesive.
- Building wall by itself a flat, vertical contact surface for a support of the reinforcement on the building wall.
- the reinforcement is 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.
- the reinforcement can be secured in the respective Anspreßgna on the building wall.
- the central hole in the reinforcement is formed as a through hole and the clamping is done with a nut on the threaded rod.
- 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 Spann negotiatel also includes a lever arm, with which the torque is applied for the tension.
- lever arm is at the same time designed as a ratchet and can therefore be moved back and forth during clamping.
- Bonding of the threaded rod is not overloaded when bracing the reinforcement.
- 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, in the hole cross-section of the
- the threaded rod can then also be referred to as an anchor.
- Touching surface 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 there are less
- the reinforcement causes a stiffening of the threaded rod.
- 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, still more preferably has a dimension which is at least equal to 0.5 times the thickness of the thermal insulation, and most preferably has a dimension which is at least equal to 2/3 of the thickness of the thermal insulation.

- the low heat transfer coefficient is advantageous for the insulation.
- the gain can increase in the direction of the
