Description

The The invention relates to an anchor system made of a threaded rod, a Mounting adapter and a threaded bolt with a nut, for attachment a load on an insulated wall or ceiling, with the threaded rod is fixed in the supporting area of the wall or ceiling and on her free end over Mounting adapter carries the load-bearing threaded bolt.

thermal isolated facades usually consist of a load-bearing wall, one on the outside arranged insulation and a plaster applied thereto. The Insulation, which can only serve sound insulation, is made of materials like foamed Styrofoam, glass wool, rock wool and the like made. At this Insulations can be in usually due to the low compressive and tensile strength no major loads be attached directly. Possibly. is only isolation instead of isolation a cavity exists. The anchor system thus carries a load that is opposite to the viable Underground of wall, ceiling or floor in mm, in centimeter or decimetral distance.

Should now an external load, eg. As a heavy outdoor lamp, a railing or an awning must be attached to such a wall, so must the force acting on the plaster by the load compressive force z. B. by supported on the supporting wall Spacer tubes are included.

to Saving of these spacer tubes is from the leaflet "fischer Thermax "the Fischer Germany Vertriebs GmbH, Issue date 04/2006, this a thermal separation module for the anchoring of awnings known. The separation module, a mounting adapter-like Plastic sleeve with double-sided threaded hole, is part of a Anchor system. In this system, in the iso lated wall a Threaded rod attached. On the threaded rod is the plastic sleeve screwed. In the still free threaded hole of the plastic sleeve is screwed in a threaded pin. On the threaded pin is the awning holder deferred and fixed with a nut. The awning holder is thereby clamped between the plastic sleeve and the nut. In this anchor system, the awning holder after touchdown on the threaded pin, re of the distance to the wall, no longer be adjusted.

From this document DE 60 2004 001 831 T2 a rod device is known which consists of a threaded rod, a nut and a glued dowel. The rod device is used, inter alia, the attachment of crash barriers on concrete carriageways. The bar device is designed so that it can easily be removed from the dowel carrying it after accidental demolition of the guardrail. For this purpose, the threaded rod has a right-hand thread in the section which is screwed into the plug-in dowel, while it has a left-hand thread in the region of the nut with which the guardrail is bolted to the roadway. Between both threaded sections is a thread-free blocking zone. Is now the guardrail demolished, z. B. pulled out of its anchorage, the above-ground bent threaded rod must be unscrewed from the dowel to be replaced by a new can. To unscrew the threaded rod, the nut is screwed down until it rests against the blocking zone. Upon further rotation of the nut - in the same direction of rotation - the threaded rod in the dowel is released due to its right-hand thread.

Of the The invention is therefore based on the problem of providing an anchor system, with the distance of the load from the wall, the ceiling or the bottom even then - at easiest handling and longevity - remains adjustable when the Load on the supporting threaded bolt or pre-fixed is.

The Invention is solved with the features of the main claim. To the threaded bolt is part of the mounting adapter. The mounting adapter exists either a threaded bolt and a cylinder bolt, wherein First, the cylinder pin has an outer diameter that is larger as the thread diameter of the threaded bolt, wherein secondly the Cylinder bolt has a flat stop surface towards the threaded bolt, which is aligned normal to the centerline of the anchor system and wherein third, on the side facing away from the threaded bolt of the Cylinder bolt is a threaded hole, with the mounting adapter on the free end of the support member is screwed, or the mounting adapter is a threaded bolt, in the central region rigidly a stop plate and sits in one - im Support element existing - threaded hole is screwed.

With the invention, an anchor system is created, with the help of a load on a z. B. insulated wall or ceiling can be precisely adjusted. The adjustment takes place here perpendicular to the surface of the wall or ceiling. It still works even when the load on the wall or on the ceiling is already positioned, so all supporting parts are behind the load, are generally no longer accessible. This is possible due to the load-bearing element longitudinally displaceably arranged load-receiving mounting adapter. The mounting adapter can on the support element, for. B. a threaded rod, are threaded back and forth over a thread. This is the mounting adapter from the front, so from the accessible gland side, z. B. adjusted by means of a Allen screwdriver in depth, whereby the distance of the load is adjusted relative to the wall or ceiling.

Further Details of the invention will become apparent from the uncited dependent claims and the following description of schematically illustrated embodiments:

The 1 and 2 show one on a building wall ( 10 ) by means of an anchor system ( 20 - 75 ) fixed load ( 90 ). Per load ( 90 ) are usually a group or more groups of these anchor systems ( 20 - 75 ) used.

The building wall ( 10 ) has in the exemplary embodiment only by way of example a three-layer wall structure. It consists of a load-bearing wall area ( 11 ), here z. B. a concrete wall, a heat insulation ( 12 ), for example, with the wall area ( 11 ) glued polystyrene panels, and a plaster ( 13 ). The outer surface of the plaster ( 13 ) is here the wall or ceiling outer surface ( 14 ) to which the load to be mounted can come to rest.

The anchor system comprises a threaded rod ( 20 ), a mounting adapter ( 30 . 50 ) and at least one mother ( 70 ). Possibly. still include various washers ( 71 ) and sealing elements ( 26 . 75 ) to.

The threaded rod ( 20 ) has, for example, an M16 thread. At its free end ( 21 ) it has z. B. on a hexagon socket. Instead of the hexagon socket, it can also have a transverse slot, a driving lug, an external hexagon or the like there, provided that these driving means do not hinder the use of the threaded rod thread due to their outer diameter. The threaded rod has a length that exceeds the thickness of the thermal insulation by about three to eight inches. Five to eleven inches of this length stuck over a dowel ( 16 ) in the supporting wall area ( 11 ).

The length of the threaded rod ( 20 ) is in the variant of the 1 and 2 usually chosen so that the screwed threaded rod ( 20 ) about two to four centimeters in front of the wall or ceiling outer surface ( 14 ) ends. The threaded rod ( 20 ) to 1 is a support element which, at least in the region of the free end ( 21 ) carries a metric thread or a similar other thread. You can z. B. also be a hanger bolt.

The large mounting adapter ( 30 ), see. also 7 , consists of an outside z. B. smooth-walled cylinder bolt ( 41 ) and a threaded bolt ( 31 ). Both parts are made as a turned part of a piece of metal. But they can also be positively, positively or materially connected rigidly connected to each other.

The threaded bolt ( 31 ) is z. B. about 25 millimeters long and has an M10 thread. In its free end is a hexagon socket ( 32 ) incorporated. The cylinder bolt ( 41 ) is about 40 millimeters long. Its diameter is about 22 millimeters. Its the threaded bolt ( 31 ) facing end face forms a flat stop surface ( 43 ) for the load to be fastened ( 90 ). In the back face ( 45 ) of the cylinder bolt ( 41 ) is a central threaded hole ( 42 ) incorporated. Its usable internal thread length is approx. 30 millimeters.

Of course, the outer surface of the cylinder bolt ( 41 ) z. B. also be polygonal, barrel-shaped or frustoconical. In the latter form, the truncated cone tapers with increasing distance from the stop surface ( 43 ).

For the preparation of the assembly of a load ( 90 ) by means of the anchor system, the building wall ( 10 ) drilled out first. The outer diameter of the drilling tool is here on the outer diameter of the anchor ( 16 ) Voted. The depth of the dowel hole ( 15 ) is so large that the dowel ( 16 ) - if possible - completely in the supporting area ( 11 ) the building wall ( 10 ) can be inserted. After setting the dowel ( 16 ), the threaded rod in the dowel ( 16 ) z. B. anchored by screwing. For a firmer plaster, the dowel hole in the front area is wiped down by a few millimeters, so that later there is the mounting adapter has enough space.

Possibly. can the threaded rod ( 20 ) at the end which is in the load-bearing wall area ( 11 ) is plugged in, dowel-like spreading elements, the z. B. under a hitting the threaded rod ( 20 ) spread apart. Here then can be dispensed with a dowel. Also, the threaded rod ( 20 ) into the corresponding borehole in the supporting wall area ( 11 ) are glued.

On the free end ( 21 ) of the threaded rod ( 20 ), that after 1 about 20 millimeters behind the plaster ( 13 ), the mounting adapter ( 30 ) with a Allen screwdriver. The mounting adapter ( 30 ) is z. B. screwed in so far that the stop surface ( 43 ) with the plaster ( 13 ) is flush or slightly beyond this, cf. 1 ,

After the required number of anchor systems have been attached to the building wall, the load ( 90 ), z. B. in the form of a flange plate, with their holes ( 91 ) on a group of z. B. four threaded bolts ( 31 ). At least on the loaded with train threaded bolts ( 31 ) are used for preliminary holding and aligning the nuts ( 70 ) - without tightening - screwed on. Possibly. be under the nuts ( 70 ) nor washers ( 71 ) placed.

For aligning the flange plate or the load ( 90 ) opposite the building wall ( 10 ), the mounting adapters ( 30 ) over its hexagonal edge ( 32 ) on the fixed ends ( 21 ) of the threaded rods ( 20 ) by alternately unscrewing and screwing in until all stop surfaces are precisely aligned with the optimally aligned load ( 90 ) issue. Finally, the remaining washers ( 71 ) and nuts ( 70 ) and all nuts ( 70 ) - with a respective holding the mounting adapter ( 30 ) by means of a Allen tool - tightened, cf. 2 ,

In the 3 and 4 a comparable anchor system is shown. Here is the threaded rod ( 20 ) a little longer. When installed, it can reach up to five millimeters to the surface ( 14 ). In addition, she has in the free end ( 21 ) a central threaded hole ( 22 ). The threaded rod ( 20 ) is a support element, which may also be a tube at its free end ( 21 ) has an internal thread.

The small mounting adapter ( 50 ), see. also 8th , consists of a threaded bolt ( 51 ) with an M8 thread, in the middle region of a z. B. five millimeter thick stop washer ( 61 ) is molded or welded. The molded variant is in 8th shown. The stop disc ( 61 ) has an outer diameter, the z. B. is slightly smaller than the inner diameter of the Dubelbohrlochs ( 15 ). The entire threaded bolt ( 51 ) is about 50 to 60 millimeters long. Behind the stop disc ( 61 ) is the threaded bolt section ( 62 ), while in front of the stop disc ( 61 ) the threaded bolt section ( 64 ), cf. 8th , The rear threaded bolt section ( 62 ) is here z. B. longer than the front threaded bolt section ( 64 ).

For mounting the load ( 90 ) the mounting adapter ( 50 ) into the threaded hole ( 22 ) of the threaded rod ( 20 screwed in). To 4 located in the area of the hexagon socket ( 23 ) an annular groove ( 25 ), in which a sealing ring ( 26 ) sits. This sealing ring ( 26 ) protects the threaded hole ( 22 ) from moisture penetration. Possibly. is used instead of the sealing ring ( 26 ) uses a plastic clamping ring, as he z. B. is used in self-locking nuts.

To 4 sits around the stop disc ( 61 ) as a highly elastic seal ( 75 ) a kind of sponge rubber. The latter bridges a gap between 0.5 and 5 millimeters. This optional seal ( 75 ) prevents rain or spray water from entering the plug hole ( 15 ) penetrates.

The assembly of the load ( 90 ) using the small mounting adapter ( 50 ) is directly comparable to that of the large mounting adapter ( 30 ). The small mounting adapter ( 50 ) is smaller than the larger one, however, for smaller loads ( 90 ) designed.

The 5 shows a further variant of the anchor system. Here, a building wall is shown, the z. B. only a relatively thin insulation ( 12 ) under the plaster ( 13 ) having. The from the 1 to 4 known threaded rod ( 20 ) is here by a dowel ( 24 ) replaced. The dowel ( 24 ), the z. B. flush with the supporting area ( 11 ) the Wall ( 10 ) has an internal thread in which the mounting adapter ( 50 ) is screwed adjustable. He is in the dowel hole ( 15 ) z. B. by gluing, potting or otherwise attached. As an adhesive, for example, a foaming one or two-component adhesive can be used.

In 6 an anchor system is shown with which, for example, a load ( 90 ) in the form of facade or ceiling tiles on a substrate ( 11 ) adjustable. Here, the anchor system forms the combination of a profile carrier ( 27 ), the mounting adapter ( 50 ) and the mother ( 70 ). The profile carrier ( 27 ), which may also be an angle profile, a U-profile or the like, is directly on the ground z. B. by means of screws ( 29 ) attached. He has a threaded hole ( 28 ) in which the rear threaded bolt section ( 62 ) is screwed. The latter has a larger thread here knife than the front threaded bolt section ( 64 ).

All metallic parts of the anchor system, in particular the threaded rod ( 20 ), the mounting adapter ( 30 . 50 ) and the mother ( 70 ) are z. B. made of a chromium-nickel steel, galvanized steel or an aluminum alloy. Possibly. Parts of the anchor system can also be made of a ceramic material or plastic.

at the description of the figures was exemplary attachment to a vertical building wall described. A comparable attachment to a sloping wall, on a floor or a horizontal building ceiling is not excluded. It is also possible in general comparable anchor systems in other sizes than specified. The component dimensions arise z. B. from the male forces the load to be fastened.
