Definitions

  • the invention relates to a ceiling for a building, which is mounted at least on the edge and is formed as a composite ceiling substantially with a Switzerland-part ceiling in the tension zone and with a pressure-stable material pressure partial ceiling in the pressure zone, wherein the partial ceilings on shear connector connected to each other.
  • a composite ceiling with a arranged in the tension zone wood ceiling and a arranged in the pressure zone concrete ceiling is known.
  • the two sub-ceilings are connected in the course of their longitudinal extent by means of expanded metal strips, which engage respectively in longitudinal slots of the wood ceiling and the concrete ceiling. This requires a closest possible arrangement of the sub-ceilings, since intermediate layers adversely affect the thrust connection on the expanded metal strip.
  • the composite ceiling is thus comparatively heavy when dimensioned for heavy loads.
  • Object of the present invention is to provide a composite ceiling of the type mentioned, which has a high load capacity with low weight, is easy to produce and has a good impact sound insulation.
  • the thrust connections between the pressure sub-ceiling and the train sub-ceiling are provided in the edge regions or bearing areas of the ceiling.
  • the intermediate area of the ceiling between the two partial ceilings can be made virtually free even with regard to structural measures for the load-bearing capacity of the ceiling, since the distance between the partial pressure ceiling and the tensile partial ceiling can be varied without influencing the thrust connections. So can be chosen comparatively large for a light and yet highly resilient ceiling, the distance between the two partial ceilings.
  • the free space can be used for installations and / or insulating material.
  • the mutually spaced partial ceilings also provide good decoupling and sound absorption.
  • the pressure sub-ceiling and the train sub-ceiling are connected to each other in the intermediate region between their thrust connections via acting across the ceiling plane tensile and / or pressure connectors.
  • train-pressure connector deformation of the pressure partial ceiling is counteracted in particular for large spans and / or loads.
  • a practical embodiment of the invention provides that the train sub-ceiling in the region near the edge on opposite sides as a push connector push-stop elements for the Having front ends of the pressure part ceiling and that the stop elements are made of dimensionally stable material and have a shear-stable connection to the train ceiling.
  • the thrust forces occurring are hereby transmitted from the pressure sub-ceiling via the outer ends directly to the rigidly connected to the train ceiling ceiling stop elements.
  • the dimensionally stable stop elements in combination with their shear stable connection with the Switzerland-Teildecke results in a rigid ceiling construction.
  • the shear-stable connection between the thrust-stop elements and the Switzerland-part ceiling is formed by a substantially full-surface adhesive bond.
  • bonds give a shift-stable connection.
  • the thrust-stop elements can be designed so that even large-area contact surfaces are present, are transferable stable on the high shear forces.
  • the push-stop elements can be connected via a tie-down with the train ceiling. This additional anchoring is particularly effective when the two partial ceilings are spaced from each other and acts on the push-stop elements a contrasting overturning moment when thrust
  • the ceiling is designed as a concrete wood-based composite ceiling, wherein the pressure-part ceiling consist essentially of concrete and the train-part ceiling substantially of wood. With such floor slabs many applications can be covered.
  • the provided in the pressure zone Concrete sub-ceiling essentially formed from precast concrete parts.
  • the floor slab is expediently composed of a plurality of longitudinal ceiling elements arranged next to one another, each of which consists of a tensile sub-ceiling located in the tensile zone and a partial pressure ceiling located in the pressure zone.
  • the installation of the floor ceiling is simplified because the individual longitudinal elements are easier to handle. For larger spans the ceiling longitudinal elements are composed of several sections.
  • At least a part of the precast concrete parts of the side-by-side longitudinal ceiling elements can be connected to one another. As a result, a stable composite of the ceiling longitudinal elements is formed.
  • floor slab 1 may consist of a single ceiling longitudinal element 2 or from several, juxtaposed longitudinal ceiling elements 2.
  • the floor slab 1 is mounted at the edge at opposite ends on supports 5, one of which is dashed lines in Fig. 1 is indicated.
  • the other support is located at the opposite end of the longitudinal extent of the ceiling longitudinal element 2 and the floor slab.
  • the floor slab is formed as a composite ceiling with a preferably consisting of wood train sub-ceiling 3 in the tension zone and with a pressure-stable material, preferably made of concrete pressure sub-ceiling 4 in the pressure zone.
  • the ceiling 1 is thus formed in the exemplary embodiment as a concrete wood-based composite floor.
  • thrust-stop elements 6 are made of dimensionally stable material and are connected to the tensile blanket 3 with good shear stability.
  • the shear-stable connection is formed in particular by a substantially full-surface adhesive bond.
  • the outer ends 8 of the pressure-part cover 4 are the outer ends 8 of the pressure-part cover 4 at.
  • the thrust-stop elements 6 Due to the high-strength and deformation-resistant adhesive bond of the thrust-stop elements 6 with the underlying Switzerland-part ceiling 3, which consists of glued laminated timber in the embodiment, the thrust forces occurring under load of the floor slab 1 from the pressure-part cover 4 on the stop elements 6 on the underlying Transfer train ceiling 3.
  • the thrust-stop elements 6 are also preferably made of wood.
  • the Fig. 4 to 9 show different measures to additionally absorb the overturning forces occurring when thrust by the pressure-partial cover 4.
  • cross-link safeguards 4 to 6
  • the 4 to 6 are provided for Queryaksterrorism Vollgewindeschrauben 11, which counteract a lifting of the stop elements 6.
  • full-threaded screws 11 also preferably glued threaded rods can be provided.
  • the Queryakêt Klien are arranged at right angles to the ceiling plane in the embodiment. The tipping moment introduced by the pressure partial cover 4 into the stop elements is the greater, the farther the two partial covers 3, 4 are spaced from one another, so that transverse pull locks are provided, in particular for large distances and high ceiling loads.
  • FIGS. 7 to 9 show a variant of a Traction protection of the stop elements 6.
  • a metal, in particular steel angle 13 on the inner end face 7a he stop elements 6 is preferably arranged at the upper region and thus connected to the stop elements 6.
  • steel screws 14 which are screwed into the board stack 10 of the train-part cover 3 attack. This arrangement also acts as a hold-down for the stop elements 6 at high tipping loads by the introduction of compressive forces from the pressure-blanket. 4
  • the inner end face 7a of the stop elements 6 extends obliquely and in particular approximately at right angles to the transverse forces occurring in accordance with the double arrow Pf 4 in Fig. 3 ,
  • the provided in the pressure zone partial pressure ceiling consists in the illustrated embodiments of precast concrete elements 15 which abut each other in the longitudinal direction of each end.
  • the respective outer precast concrete elements 15 rest on the push-stop elements 6.
  • at least between the individual precast concrete elements 15 first joints 19 are provided, which are filled after laying the precast concrete parts with grout. In this gap region, the tension connectors 18 are arranged.
  • an elevation may be provided, which results in a flat ceiling surface at full load on the finished ceiling and thus more comfort. Also, a better static utilization is possible.
  • precast concrete parts eliminates the curing time of the concrete on the construction site and thus there are no construction delays. In addition, no shrinkage of the concrete occurs, so that a subsequent deformation of the entire component is excluded by creep.
  • the floor slab 1 can be composed of a plurality of longitudinal ceiling elements 2 arranged next to one another.
  • the ceiling longitudinal elements 2 may be composed of several sections. At least part of the side-by-side longitudinal ceiling elements can be connected together to form a stable composite as a whole.
  • the ceiling longitudinal elements 2 each have two parallel to each other, formed by glued laminated pile 10 train ceiling 3, wherein the two spaced board layer stack 10 are arranged on a transverse layer 16 of side by side arranged boards 17 and connected. Between the transverse layer 16, the plate-shaped ( Fig.1 to 6 ) or arranged side by side boards ( Fig. 7 to 8 ) may be formed, here is still an intermediate layer 20 is provided.
  • the wooden partial ceiling may have a finished bottom view and optionally be formed as an acoustic ceiling with sound-absorbing structure.
  • the ceiling longitudinal elements 2 can also be used for a roof structure, especially for large wingspan, in which case the pressure-part cover 4 can also be made of wood.
