Definitions

  • the invention relates to a lattice girder-free Ceiling construction, especially a large one Formwork construction for reinforced concrete slabs, with a plurality of ceiling elements, as well as a ceiling element for such Ceiling construction.
  • Composite formwork ceilings according to EP-A-0 164 330 are known, which are made of load-bearing steel lattice girders Connection parts attached formwork panels, which simultaneously represent the later ceiling surfaces. at have a comparable composite formwork according to DE-A-4341856 the lattice girder two lower chord bars and one upper chord bar on. The at a distance from the assigned formwork panel Trending two lower chord bars are in line mutually aligned U-shaped brackets, which with their angled flange sections each with the assigned formwork panel are screwed.
  • the grid-free ceiling construction especially large-area formwork construction for Reinforced concrete ceilings are provided with a number of Ceiling elements that are blunt with their side edges butt together, the ceiling elements being a base plate, on the base plate in line with each other U-shaped bracket, each with a web, two legs and angled at the free ends of the legs Have flange sections, the flange sections are each screwed to the base plate, and Have individual longitudinal bars that in the of the legs and the webs of the U-shaped brackets formed corners are fastened with a welded connection such that they have a distance from the base plate so that the Individual longitudinal bars are pressure-transmitting and the base plate is train-transferring, as long as none or a liquid Concrete layer lies on the base plate, i.e. the Concrete layer is not yet load-bearing, and the individual longitudinal bars are transferring after that on the base plate overlying concrete layer, into which the individual longitudinal bars are embedded and
  • the U-profile-shaped bracket are thus on the Base plate set that their web at a distance from the Base plate is arranged and its legs from the web to the Base plate run. At the ends of the base plate free ends of the thighs are outward from the thighs angled flange sections available with which the U-shaped Bracket is screwed to the base plate.
  • the ceiling construction can at the same time as formwork slab and as load-bearing reinforcement for the finished concrete ceiling.
  • the individual longitudinal bars are in sufficient Distance from the base plate so that it is the dead weight of the built ceiling construction and that when casting the Loads due to the weight of the concrete as pressure rods.
  • the base plate itself serves the ceiling construction Transfer of shear forces between the pressure element and the Tension element in this support structure is due to the shear-resistant welded connections or screw connections guaranteed.
  • the formwork ceiling elements of the ceiling construction on the Thickness of the concrete slab to be created are coordinated in such a way that the individual longitudinal bars in the lower area, especially in bottom third of the finished concrete surface take the individual longitudinal bars in the finished state of the concrete ceiling the tensile forces of the reinforced concrete ceiling. In the hardened state the concrete absorbs the corresponding compressive forces.
  • Ceiling elements can be attached to the joints using strips or Be covered with tape and / or screwed with tabs.
  • the attachment of the individual longitudinal bars to the U-profile can be achieved by welding completely over the entire length of the bracket element. Is preferred however, one attachment with one welding spot per connection between a single longitudinal bar and a U-shaped bracket intended. Can be advantageous for connecting to a Single longitudinal bar also has a weld spot at each end of the U-profile Strap may be provided.
  • the U-shaped brackets can also be used any dimensional ratios may be provided are suitable, the desired relative position between To enable individual longitudinal bars and base plate. It is conceivable to use very short profile elements in which the Web width of the U-shaped bracket is significantly larger than the length of the U-shaped bracket. Are preferred however, U-profile-shaped brackets are used, the web width of which is considerably shorter than the length of the U-shaped bracket. Such a construction makes it possible in connection with a a suitable welded joint, a particularly high one To ensure bending stress of the composite ceiling construction.
  • the base plates of the ceiling elements of the invention Ceiling construction can be made from any suitable materials be made. However, cementitious ones are preferred Material plates used. These are simple and inexpensive to manufacture, and are particularly easy Connect to the reinforcement by means of a screw connection. Moreover such plates can be made without problems without the dimensions to change, with the help of integrated steel reinforcements be reinforced to carry certain loads.
  • Such a cement-bound material plate can be made of various starting materials. Prefers however, a wood cement board is used because wood is a Material is that for a pleasant indoor climate, in particular a regulated moisture balance.
  • a ceiling element With regard to the ceiling element, the problem is invented solved with a ceiling element according to claim 6.
  • Das grid-free ceiling element for a ceiling construction provided with a base plate, in series on the base plate U-shaped brackets arranged in alignment with each other each a web, two legs and at the free ends of the Have legs formed angled flange sections, the flange sections being screwed to the base plate are, and single longitudinal bars, which in the by the Legs and the webs of the U-shaped bracket formed Corners each fastened with a welded connection are that they are a distance from the base plate exhibit.
  • Fig. 1 is a ceiling construction according to the invention with two adjacent ceiling elements can be seen, the is shown in plan view.
  • the base plates 1 are rectangular. On each base plate 1 are parallel rows in the longitudinal direction attached by U-shaped brackets 2. On every row of aligned U-shaped brackets 2 are two Single longitudinal bars 3 attached, which over the two Extend transverse edges 1a of the base plates 1. The projecting ends 3a of the individual longitudinal rods are to the Ceiling-supporting walls 7 attached (see. Figure 4), so that the Single longitudinal bars 3 for the finished reinforced concrete ceiling Function.
  • the base plates 1 arranged next to one another of the two ceiling elements are with connecting elements 6 interconnected.
  • the U-shaped bracket has 2 a web 2b, legs 2c and of the legs 2c of the U-profile Bracket 2 angled flange sections 2d.
  • the U-shaped bracket 2 is located on these flange sections 2d attached to the base plate 1 by means of screws 4.
  • Fig. 3 From Fig. 3 it can be seen that four screws 4 each Attachment of a U-shaped bracket 2 to the base plate 1 are provided.
  • the individual longitudinal bars 3 are each with two Spot welds 5 on the longitudinal ends 2a of the U-profile Bracket 2 attached.
  • the U-shaped bracket 2 have a considerably greater length than the width of the web 2b of the U-profile Temple 2, they are about twice as long.
  • the ceiling elements are in front of the Pouring the concrete connected to the load-bearing walls 7 and supported with a few support elements 8.
  • the then on the ceiling element is cast concrete layer with a dash-dotted line.
  • the infused Concrete layer is so thick that the reinforcement with the U-profile Iron 2 and the individual longitudinal rods 3 in lower third of the concrete layer.
