Definitions

  • the invention relates to an arrangement for connecting a substantially vertical building wall, in particular a load-bearing wall, to a floor or ceiling slab and for forming a wall connection system. Furthermore, a molded component for arranging between a building wall and a floor or ceiling slab, for supporting the building wall on the floor or ceiling slab or for supporting the ceiling slab on the building wall, is described.
  • Arrangements for connecting a building wall to a floor or ceiling slab are known, which as wall connection systems create a connection between a preferably cast vertical concrete wall and a horizontal floor or ceiling slab arranged underneath and transmit compressive forces in a vertical direction.
  • arrangements known from the prior art are intended to achieve the greatest possible thermal decoupling between a floor slab and a building wall arranged on it, in particular a cast concrete wall.
  • an arrangement for connecting a building wall to a floor or ceiling slab which has a pressure-transmitting and insulating connection element for connecting two cast components with an insulating body for thermal separation of the components.
  • the insulating body has one or more pressure elements made of a concrete material that penetrate the upper and lower support surface of the insulating body.
  • the pressure elements are arranged at intervals from one another within the insulating body, which is predominantly made of an insulating material, with the spaces between the pressure elements being filled with the insulating material.
  • connection elements known from the prior art However, they have the disadvantage that shear forces, i.e. forces that act in the longitudinal direction of the wall, can only be absorbed to a limited extent and introduced into the floor or ceiling slab below.
  • Another disadvantage of the state of the art is the same load deformation behavior of the connecting elements, which means that deformation and force transmission are not decoupled. This can lead to an uneven distribution of force along the building wall and possibly an uneven expansion of the wall in its longitudinal direction.
  • AT 002 799 U1 reveals a ceiling formwork block with integrated thermal insulation, which forms the ceiling formwork after bricklaying.
  • DE 200 08 570 U1 discloses a brick-shaped thermal insulation element for thermal decoupling between wall parts and floor/ceiling panels, consisting of at least one pressure-resistant support element and at least one thermally insulating element, wherein the thermal insulation element has at least one anchoring projection on its outer side, which serves for the positive connection to the adjacent wall part.
  • the present invention is based on the object of addressing one of the problems mentioned.
  • at least one alternative to the known arrangements is to be created.
  • the invention takes into account the fact that, particularly in the case of long building walls, mechanical stresses can arise between the building wall and a floor or ceiling slab due to different expansions, which are particularly thermally caused.

  • Such a sliding bearing module transfers vertical forces from the building wall to the ceiling or floor slab, or vice versa, but allows compensating movements in the longitudinal direction of the wall. At least it transfers comparatively little force in the longitudinal direction of the wall.
  • the sliding bearing module is adapted accordingly in a connection area or contact area.
  • the connection area or contact area is the one in which the shaped module comes into contact with the building wall and/or the floor or ceiling slab and via which vertical forces are transferred between the shaped module and the building wall or the floor or ceiling slab.
  • the compensating movement is permitted in this connection area or contact area.
  • the contact surface and/or the bearing surface can form the connection area.
  • At least one fixed bearing block is provided to fix the wall relative to the floor or ceiling slab, or vice versa.
  • a fixed bearing block transfers vertical forces from the building wall to the ceiling or floor slab, or vice versa, without allowing compensating movements in the longitudinal direction of the wall.
  • the fixed bearing block can also be used in a connecting section or contact area be designed accordingly, namely by not allowing any compensating movements there, but rather by being able to transfer shear forces, in particular high shear forces in the longitudinal direction of the building wall. This particularly applies to high shear forces such as those that typically occur in building stabilization.
  • the contact surface and/or the support surface can form the connecting section.
  • One way to design the contact surface and/or the support surface of the fixed bearing component is to design it in such a way that a positive connection is achieved.
  • a toothed joint which can also be referred to as a wave profile, can be provided. This can achieve a firm connection, or at least a good transmission of the thrust forces.

  • the sliding bearing modules in the sliding bearing area can ensure that possible changes in the length of the building wall and the associated shear forces in the longitudinal direction of the building wall, caused by changes in ambient temperature, are balanced out or distributed across the sliding bearing area. This enables a uniform longitudinal displacement of the corresponding section of the building wall to be implemented along the sliding bearing area.
  • a or the sliding bearing region is arranged at at least one end of the arrangement and a or the fixed bearing region is arranged in a central region, wherein in particular a sliding bearing region is arranged at each of the two ends of the arrangement and the fixed bearing region is arranged in between.

  • a sliding bearing area with one, two or more sliding bearing blocks is arranged on both sides of the fixed bearing area.
  • compressive forces arising within the building wall are then reduced on both sides of a fixed bearing area that transmits and/or absorbs shear forces.
