Definitions

the invention relates to a ceiling construction, in particular a large-area formwork construction for reinforced concrete ceilings, with a plurality of ceiling elements, and a ceiling element for such a ceiling construction.
Composite formwork ceilings according to EP-0 164 330 are known, which consist of load-bearing steel lattice girders with formwork panels attached to them by means of connecting parts, which at the same time represent the later surface of the ceiling.
the top chord of the steel lattice girder takes over the compressive forces which occur in the assembled state and during concreting and hardening of the concrete. After the concrete has hardened, this top chord together with the sloping connecting rods of the steel lattice girder is statically superfluous in the field reinforcement of the ceiling.
the conventional composite structures also have the disadvantage that they take up a considerable amount of space, so that they can only be transported as prefabricated components at great expense. Their construction is also associated with high manufacturing costs and is rather expensive.
the invention solves the problem of creating a composite formwork slab and slab elements for it, the steel reinforcement of which can take on load-bearing functions both during slab production and in the finished slab, so that it can be credited in terms of construction, and which can also be produced cost-effectively.
this problem is solved according to the invention with a ceiling construction, in particular a large-area formwork construction for reinforced concrete ceilings, with a plurality of ceiling elements which abut one another with their lateral abutting edges, the ceiling elements being a base plate, U-profile-shaped in alignment with one another on the base plate Hanger, which each have a web, two legs and angled flange sections formed on the free ends of the legs, the flange sections each being screwed to the base plate, and having individual longitudinal bars which in each case in the corners formed by the legs and the webs of the U-shaped bracket are fastened with a welded connection in such a way that they are at a distance from the base plate, the individual longitudinal bars being pressure-transmitting and the base plate being tension-transmitting, as long as there is no or a liquid concrete layer on the base plate, i.e. the concrete layer is not yet load-bearing, and the individual longitudinal bars are tension-transferring after the concrete layer lying on the base plate, in which
the U-shaped brackets are thus placed on the base plate in such a way that their web is arranged at a distance from the base plate and their legs run from the web to the base plate. At the free ends of the legs ending on the base plate there are flange sections angled outward from the legs, with which the U-shaped bracket is screwed to the base plate.
the ceiling construction can serve both as formwork slabs and as load-bearing reinforcement for the finished concrete slab.
the individual longitudinal bars are at a sufficient distance from the base plate so that they bear the inherent loads of the constructed ceiling structure and the loads that occur when the concrete is poured due to the dead weight of the concrete as pressure rods.
the base plate itself serves as the tension element in this load-bearing ceiling construction. The transmission of the shear forces between the pressure element and the tension element in this support structure is ensured by the shear-resistant welded connections or screw connections.
the formwork slab elements of the slab construction are matched to the thickness of the concrete slab to be created in such a way that the individual longitudinal bars come to rest in the lower area, especially in the lower third, of the finished concrete slab, the single longitudinal bars absorb the tensile forces of the reinforced concrete slab when the concrete slab is finished. In the hardened state, the concrete absorbs the corresponding compressive forces.
the ceiling elements which abut one another with their lateral abutting edges can be covered at the joints by means of a strip or adhesive tape and / or screwed together with tabs.
the individual longitudinal bars can be attached to the U-shaped brackets according to the invention by complete welding over the entire length of the bracket element.
an attachment with a welding point per connection between a single longitudinal bar and a U-shaped bracket is preferably provided.
a welding spot can advantageously also be provided at each end of the U-shaped bracket.
the U-profile-shaped brackets can be provided with any dimension ratios that are suitable for 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 greater than the length of the U-shaped bracket. However, U-shaped brackets are preferably used, the web width of which is considerably shorter than the length of the U-shaped bracket. Such a construction, in conjunction with a suitable welded joint, makes it possible to ensure a particularly high bending load on the composite ceiling construction.
the base plates of the ceiling elements of the ceiling construction according to the invention can be made from any suitable materials.
cement-bound material boards are preferably used. These are easy and inexpensive to manufacture, and can be connected to the reinforcement particularly easily by means of screw connections.
slabs can be reinforced without problems, without having to change the dimensions, with the aid of integrated steel reinforcements for carrying certain loads.
Such a cement-bonded material plate can be made from a wide variety of starting materials.
a wood-cement board is preferably used, since wood is a material that ensures a pleasant room climate, in particular a regulated moisture balance.
a ceiling element for a ceiling construction with a base plate, U-shaped brackets aligned in series with one another on the base plate, each having a web, two legs and angled flange sections formed on the free ends of the legs, wherein the flange sections are each screwed to the base plate and individual longitudinal rods which are each fastened in the corners formed by the legs and the webs of the U-shaped bracket with a welded connection such that they are a distance from the base plate exhibit.
a ceiling construction according to the invention with two adjacent ceiling elements can be seen, which is shown in plan view.
the base plates 1 are rectangular.
On each base plate 1 parallel rows of U-shaped brackets 2 are attached in the longitudinal direction.
the projecting ends 3a of the individual longitudinal bars are fastened to the walls 7 supporting the ceiling (see FIG. 4), so that the individual longitudinal bars 3 have a supporting function for the finished reinforced concrete ceiling.
the base plates 1 of the two ceiling elements arranged next to one another are connected to one another by connecting elements 6.
the U-shaped bracket 2 has a web 2b, legs 2c and 2c of the legs of the U-shaped Bracket 2 angled flange sections 2d.
the U-shaped bracket 2 is fastened to the base plate 1 by means of screws 4 on these flange sections 2d.
Fig. 3 From Fig. 3 it can be seen that four screws 4 are provided for fastening a U-shaped bracket 2 to the base plate 1.
the individual longitudinal bars 3 are each fastened to the longitudinal ends 2a of the U-shaped bracket 2 with two welding spots 5.
the U-shaped bracket 2 have a considerably greater length than the width of the web 2b of the U-shaped bracket 2, they are about twice as long.
the ceiling elements are connected to the load-bearing walls 7 before the concrete is poured and are supported with a few supporting elements 8.
the concrete layer subsequently poured onto the ceiling element is drawn with a dash-dotted line.
the poured concrete layer is so thick that the reinforcement with the U-shaped brackets 2 and the individual longitudinal bars 3 is in the lower third of the concrete layer.
