Definitions

  • the invention relates to a fastening arrangement with the features of the preamble of claim 1.
  • the corresponding structures are increasingly provided with insulation layers.
  • the spacers consist of an anchor rod, which is anchored in a wellbore in the building, as well as an applied on the anchor rod insulator made of plastic.
  • This insulating body forms the stop for a fastening object which is fastened by means of screws to the insulating body.
  • the publication DE 10 2006 038 906 A1 therefore proposes to fix a facade by means of a framework.
  • a relatively thin tensile metal rod is arranged at an angle of about 45 ° to the horizontal, while a pressure-stable, thermally poorly conductive pressure rod is horizontal. This ensures that high forces can be transmitted with low heat transfer.
  • the structure is relatively complex and requires a lot of space in the vertical direction on the building.
  • the invention is therefore based on the object to propose an alternative arrangement for the thermally insulated attachment of objects, in particular on the outside of structures.
  • the fastening arrangement according to the invention has a structure.
  • the structure is in particular the load-bearing structure of the building made of concrete.
  • At the structure of a concrete body is arranged at a distance, with building and concrete body are connected to each other via rods.
  • an insulating body is arranged, through which the rods extend.
  • the rods do not have to be completely surrounded by the insulating body but can lie freely. They serve to transfer the forces between the concrete body and structure, although it is not excluded that at least a small part of the forces is transmitted via the insulating body.
  • In the concrete body a borehole is introduced. Although this hole is preferably actually introduced by a drilling process.
  • a borehole in the sense of this invention could also be a cast-in rail which eliminates a cavity and can serve to fasten a fastening anchor.
  • the borehole need not be a blind hole, but a through hole may be provided as a borehole.
  • An attachment anchor anchoring the attachment is anchored in the wellbore.
  • the fastening anchor can in particular be anchored chemically, that is to say with a hardenable mass, or purely mechanically, that is to say in particular by spreading pressure. It may be an undercut anchor, that is, the hole expands towards the bottom of the hole.
  • a concrete screw can be used as a fastening anchor.
  • the attachment object is preferably a facade or part of a facade.
  • the concrete body thus serves as a suspended, thermally decoupled from the building attachment ground. Due to the combination of insulator and rods high forces can be transmitted at relatively low heat transfer.
  • the curtains of a concrete body instead of directly attaching a fastening object to the rods has the great advantage that existing on-site assembly tolerances or design errors can be easily compensated because the installer is flexible, where exactly he his attachment point, so the hole sets , Also for the design of the Overall system, there are significant benefits because the concrete body can serve as an interface. Typical calculations for facade substructures or the like can be taken over from the fastening anchor, so that only the new system of concrete body, rods and structure has to be dimensioned. Thus, proven technologies can be used for fastening, the design methods planning engineers have been known for years.
  • the concrete body is substantially strip-shaped. This means that it extends far in the horizontal direction along the structure. This ensures that the concrete body is available as a mounting base not only in narrow zones, but for example along an entire side of the building or even completely around a building.
  • the concrete body is quite slender, that is, it extends in the direction away from the structure of a maximum of 10 cm, in particular a maximum of only 8 cm.
  • These dimensions are to be regarded as dimensions that are to form a standard and are therefore to be understood in accordance with the achievable accuracy on the construction with tolerances of +/- 10%.
  • Such a slim concrete body still allows a secure and economical attachment with mounting anchors and at the same time contributes as little as possible in the horizontal direction on the building.
  • the bending moments which are introduced from the concrete body on the rods in the building, not too large.
  • the concrete body extends in the direction away from the structure of a maximum of only 6 cm.
  • the invention therefore proposes the combination of a slim concrete body with a chemical anchoring of the fastening anchor and / or an undercut anchor.
  • Such anchors require a low anchoring depth and small edge distances and therefore contribute in combination with a slim concrete body to a heavy-duty, little projecting overall structure.
  • the fastening anchor is used in particular for the transmission of horizontally acting tensile forces, as they are caused in facades mainly by wind suction forces.
  • the fastening anchor is introduced substantially horizontally for this purpose.
  • vertical forces are predominantly derived directly from the attachment object to the concrete body by a support. This substantially relieves the fastening anchor, which otherwise would have to transmit significant lateral forces depending on the height of the vertical load and would claim the concrete body in particular in the region of the wellbore. Overall, therefore, significantly larger vertical loads, in particular weights, can be removed by such a support.
  • the fastening object is fastened in a second height of the structure.
  • this second attachment may be a fastener assembly having the features previously described. For example, if only tensile forces are to be transmitted, but the second attachment can also be made even simpler, so for example, consist only of an anchored in the building tension rod.
  • the second attachment may be arranged in particular in the region of a floor slab, but also lie therebetween.
  • the single FIGURE shows a fastening arrangement 1 according to the invention in a vertical sectional representation, wherein a natural stone facade is fastened to a structure 3 as the fastening object 2.
  • the structure 3 here is a concrete structure and has, inter alia, a floor slab 4 made of concrete, cast in the edge region rods 5 and thus anchored.
  • the rods 5 protrude out of the structure 3 and through a rectangular insulator 6 therethrough.
  • the insulating body 6 connects in the horizontal direction directly to the building 3 and is made of a material with low heat transfer, such as polystyrene foam. Further in the horizontal direction, the rods 5 protrude into a cuboid concrete body 7. They are also anchored here by encapsulation.
  • the rods 5 extend partially horizontally, but in part they also extend at an angle of about 30 ° to the horizontal in order to transmit the forces occurring with the smallest possible cross-sections of the concrete body 7 on the building 3. They are made in particular of steel, optionally made of particularly corrosion-resistant steel, and each form loops 8, that is, each two rods 5 are formed from a bent rod.
  • a Reinforcing bar 9 in the horizontal direction, but perpendicular to the cutting plane, which is enclosed by a loop 8.
  • the concrete body 7 extends only 8 cm in this direction. Perpendicular thereto in the horizontal direction, that is perpendicular to the sectional plane, the concrete body 7, on the other hand, extends significantly further, namely substantially along the entire floor slab 4 which it comprises. It is thus strip-shaped, while the insulating body 6 extends, for example, only 35 cm in this direction.
  • the concrete body 7 is connected at several points of the floor slab 4 via rods 5 and insulator 6 to the building 4, wherein the concrete body 7 lie approximately on an imaginary horizontal plane.
  • a borehole 10 is introduced from the outside in the direction of the structure 3, in which by means of a curable composition (not shown), a rod-shaped, profiled attachment anchor 11 is glued. Since this is a known fastener, it will not be described in detail. Alternatively, an undercut anchor could be used.
  • the fastening anchor 11 projects out of the concrete body 7 and through a slot 12 of a console 13 therethrough.
  • the bracket 13 is secured by a nut 14 on the mounting anchor 11 and is part of the fastening object 2. It is designed as a stamped and bent part with a U-shaped profile 15 that extends vertically along the concrete body 7.
  • each two angular tabs 16, 17 from (in the figure are two tabs 16, 17 in a row). They extend from the profile 15 initially in the direction of the structure 7 and then in the vertical direction in each case away from the concrete body 7.
  • the upper tabs 16 are on the concrete body 7 and form in this area a support 18.
  • On the tabs 16, 17 each have a vertical profile 19 is attached. The attachment takes place in the region of the upper flaps 16 via further elongated holes 20 and screws 21, so that no vertical, but horizontal forces can be transmitted. In the region of the lower lugs 17, the attachment via screws 21 in circular holes, so that here forces can be transmitted in any direction.
  • a concrete body 7 is arranged.
  • a further attachment in the form of a tension rod 26 is arranged at approximately half the height.
  • the tension rod 26 is fastened with screws 21 on the vertical profile 19 and extends through an insulation board 27 through into the structure 3, wherein the attachment in the building 3 again takes place chemically.
  • the main forces that emanate from the facade as a fixing object 2 on the one hand, the vertically acting weight forces and on the other hand horizontally acting wind suction forces. These forces are introduced via the horizontal profiles 22 in the vertical profiles.
  • the weight forces are introduced via the lower tabs 17 in the console 13 and transmitted from the upper tabs 17 via the support 18 as vertical forces V on the concrete body 7.
  • the wind suction forces are in contrast transmitted over several points of the vertical profile 19.
  • they are transmitted via the upper and lower flaps 16, 17 to the console 13, from where they are introduced via the fastening anchor 11 as horizontal forces H in the concrete body 7.
  • they are introduced via tie rods 26 directly into the structure 3. This prevents, in particular, an undesired deflection or buckling of the vertical profiles 19.
  • the vertical forces V and the horizontal forces H on the concrete body 7 are removed as described above by means of the bars 5 onto the structural body 7.
  • the fastening arrangement 1 according to the invention has, in addition to the thermal insulation, the advantage that the rods 5, the insulating body 6 and the concrete body 7 can already be provided in the shell, without it depends on the exact positioning of the attachment for the facade.
  • the planning of the facade can therefore be done advantageously during the manufacture of the shell. After completion of the shell, this positioning can be done very flexible along the strip-shaped concrete body 7.
