Definitions

  • the invention relates to a flat ceiling in wood-concrete composite construction according to the preamble of claim 1 and to methods for producing such a flat ceiling.
  • Flat ceilings are uncovered ceilings in which the loads of the ceiling slab are not removed by joists but punctiform by columns, walls and building fixtures such as staircases, elevator shafts and the like.
  • Conventional flat slabs are usually made of reinforced concrete or, for larger spans of more than 9 m, of prestressed concrete.
  • Such concrete flat slabs can be easily formed and manufactured and are characterized by a low structural height, smooth ceiling soffits and the possibility of free routing of installation cables. Difficult in the production of such concrete slabs, however, is the introduction of force at the column head.
  • wood-concrete composite components which can be used for example for ceiling or wall elements. Due to the composite construction of wooden beams or board stacks and a concrete slab, the load capacity and rigidity of the components can be significantly increased compared to conventional beam structures or wood pile ceilings. Furthermore, the susceptibility to vibration of wood-concrete composite structures is much lower than in the known wood structures.
  • a wood cross-section is connected to a flat concrete layer to form a composite component, conventionally used as connecting means such as screws, bolts, nails and nail plates, threaded rods, composite dowels such as dowels or flat iron.
  • the effective bending stiffness of the composite component is essentially dependent on the rigidity of the connecting means used between the wood component and the concrete slab.
  • To achieve a high composite stiffness shifts in the composite joint of the timber component and the concrete slab are to be avoided.
  • the use of conventional fasteners often do not ensure the required shear stiffness in the composite joint.
  • various solutions for producing a shear-resistant composite joint between the wood component and the concrete slab of wood-concrete composite components have been proposed, such as so-called HBV shear connectors. These are perforated expanded metal strips which are glued in the support direction of the wood component in a groove, wherein the wood component protruding part of the thrust connector is anchored in the concrete slab.
  • connection systems for shear-resistant connection of a timber component with a concrete component are from the publications DE 103 51 989 A1 . AT 505265 B1 . DE 20 2009 004 335 U1 and EP 09 52 271 A2 known.

It is also known to combine prefabricated wood elements in conjunction with prefabricated reinforced concrete elements. The latter allows a fast construction process due to a high degree of prefabrication of the cover elements. However, it has been found that it is difficult and expensive to combine in particular prefabricated wood and concrete elements on the site by means of the known connection means so that a sufficient shear stiffness of the wood-concrete composite element is ensured.
