Definitions

  • the invention relates to one of individual basic elements composite ceiling or floor construction between two rows of vertical supports, the basic elements the ceiling construction from a plate-shaped cover Reinforced concrete (hereinafter also referred to only briefly as a concrete slab) and a steel beam assembly that is between one column is attached to each row of columns, have, as well as a method for producing the ceiling structure.
  • a plate-shaped cover Reinforced concrete hereinafter also referred to only briefly as a concrete slab
  • a steel beam assembly that is between one column is attached to each row of columns
  • a parking garage construction in which between one vertical column from each of two rows of columns, e.g. External or gable wall supports and internal or central supports, essentially horizontally aligned 1-shaped Ceiling beams are screwed. Two concrete slabs from Half the length of the ceiling beams are with one each upper web of two adjacent ceiling beams to one Support structure united.
  • the horizontal ceiling girders are constructed screwed to the vertical supports. After that, the Put concrete slabs on the ceiling beams and it becomes a Composite construction between ceiling beams and concrete slabs, i.e. an association to absorb tensile forces suitable steel girders with those to hold Pressure plates made of suitable concrete slabs.
  • the composite construction is produced in one case by that when lowering the concrete slabs onto the ceiling beams Possibly multi-course cast in the concrete slabs Steel wire loops over the webs of the ceiling beams welded head pin dowels are pushed, so that the loops when the concrete slabs rest on the Ceiling beams arranged around the headed studs are.
  • the composite construction is completed by the cavity between two concrete slabs arranged side by side ("next to" means transverse to the direction of the ceiling beams) is poured with a suitable concrete mass, with the headed dowels and the loops from the concrete mass be recorded with.
  • the parting line must be added between the two arranged one behind the other Concrete slabs of each basic element are poured (so-called Mortar lock).
  • the composite construction is carried out a variety of screw connections along the side edges the concrete slabs or along the ceiling beams.
  • the ceiling beams become light in one go bent state screwed to the vertical supports.
  • the concrete slabs are thereon as flat slabs hung up. Because of the multitude of screw connections a considerable amount of time is required during assembly.
  • the ceiling girders differ in the edition of the heavy concrete slabs already in a practically straight position bend, it can be in the manufacture of the composite structure, i.e. when screwing the flat concrete slabs with the ceiling beams to break the concrete slabs and thus take more time to assemble.
  • From DE-PS 956 685 is made of a reinforced concrete slab and two existing I-shaped steel beams below Precast reinforced concrete part for mounting on horizontal Main carriers or known among trusses.
  • the the Steel beams that form composite structures are in a distance from the edges of the reinforced concrete slab.
  • the Reinforced concrete slabs over the entire length or width of Clamping elements edge steel, wires, ropes
  • the mounting holes for the Clamping elements are cast in a known manner. Besides other connection points (especially corners) shed. Easy disassembly and reusability the finished parts are therefore not possible.
  • From US-PS 1 912 290 is also a flat, prefabricated reinforced concrete element with laterally arranged U-shaped steel profiles for resting on horizontal Ceiling beams known.
  • the side U-profiles form with the reinforced concrete slab no composite construction of the entrance defined type, since both, the reinforced concrete slab as also the U-profiles, for Absorption of both tensile forces and Pressure loads are used.
  • the US PS no indication of a positive connection between concrete and Steel profiles.
  • the reinforced concrete slabs are kept shorter than the steel profiles. The oneself cavity left after laying on the ceiling beams is then shed. Easy disassembly and The components are therefore also reusable here not possible.

  • the support frame is - as with US-A-1 912 290 - at the same height as the concrete slab, so that these basic elements do not Form a composite construction of the type defined at the beginning.
  • the side lengths of the Basic elements are different: the shorter length corresponds to the clear one Width between the supports and the longer side length of the clear width plus twice the thickness of the supports.
  • a gapless area cover the basic elements of the known ceiling construction crosswise, i.e. with alternately aligned at right angles to each other Main extension to be installed.
  • the basic elements are above and below each other tabs arranged on the flanges of the steel girders of the supporting frame screwable. To attach the basic elements to the supports and to be able to screw together, but - because the steel girders occupy the same height range as the concrete slab - cavities in the Concrete slab are brought in, which leads to incompleteness of the Surface leads.
  • the connecting tabs also provide a local one Raising the level of the road surface, which is too uncomfortable when driving over Bumps leads.
  • the present invention has for its object a To create ceiling construction of the type mentioned and to provide a process for their manufacture, at the or with which the assembly of a multi-storey building is essential simplified and the time for assembly accordingly can be shortened and its individual elements without restriction can be used elsewhere can.
  • the Covering of the basic elements from a continuous reinforced concrete slab exists, the length of which is at least the clear Corresponds to the distance between the two rows of supports, that the carrier arrangement per basic element from two U-shaped Supports exist, each with an upper flange a one-piece, through shaped elements on the flanges brought about composite construction with the concrete slab form, the one located between the flanges of each beam Bridge below the concrete slab perpendicular to it Main extension and flush to the respective side edges the concrete slab is arranged that the concrete slab has an integrated tendon at its ends and that the respective adjacent carrier two Basic elements are screwed together.
  • each basic element Due to the described length of the concrete slab, each basic element only one plate required. Through the ready-to-install composite construction of the beams the concrete slab is only for mounting a basic element a single part with the crane to the installation site to transport. This reduces the number of Transport movements for a basic element area considerably.
  • the flush arrangement of the webs of the U-beams with the side edges makes it simple, detachable Screw connection between the individual basic elements a floor or ceiling area possible.
  • This screw connection causes in connection with the integrated at the foreheads
  • Tendons a closed tension band or Ring anchors around the entire surface to form a large one Disc stability and prevents when driving over Load, e.g. of a vehicle on a parking floor, a one Shock-forming, uneven bending of neighboring ones Basic elements. Seen statically, this results from the Screw the same load option as with a common, correspondingly large I-shaped support between two neighboring basic elements.
