Definitions
- the present invention relates to a process for producing a Composite element of a concrete slab and associated support elements, especially wooden beams.
- Such composite elements of a concrete slab and supporting elements are known wherein the concrete slab and the support elements cooperate such that the Concrete plate absorb the compressive forces and the support elements, the tensile forces.
- connecting means are provided which provide a firm connection between create the concrete slab and the supporting elements. These lanyards should Thrust forces acting between the individual elements of the composite Composite element occur, transferred to the support elements and the concrete slab.
- One such composite element is known for example from EP-A-0 433 224. That in it proposed composite element consists of a concrete slab and with this interacting wooden beams. There is a toothing of the wooden beams provided, which in combination with protruding screws as Serve connecting means. For the production of this composite element is carried out that on the lateral flanks of the wooden beams formwork boards are attached to the poured from above concrete. After curing, the shuttering boards become removed and the composite element is completed.
- EP-A-0 432 484 and EP-A-0 528 450 A similar approach is also described in EP-A-0 432 484 and EP-A-0 528 450.
- a composite construction is produced on a wooden structure on which Screws are screwed in, leaving some of the screws over the wooden floor stands tall. Then the concrete is poured, thereby forming a concrete slab becomes.
- This method is used in the renovation of old buildings, as the in-situ concrete slab be applied to the floorboards of an existing ceiling construction can. Again, a formwork is needed, then poured onto the concrete slab is, after appropriate connecting means for fixed connection between Concrete slab and wooden structure have been introduced.
- CH 223498 proposed a supporting structure with wooden beams and form a concrete portion, which can be used without formwork.
- fillers are introduced, in particular hourdis bricks, between the Wooden beams are laid and then poured from the top concrete.
- lightweight panels between the Beams are placed on which in turn concrete is poured.
- Object of the present invention is therefore to provide a process for the preparation of To propose composite elements with which comparatively easy Composite elements of a concrete slab and supporting elements, in particular wooden beams, to be manufactured industrially.
- the production of the composite element takes place overhead, so to speak. It can be one in the production of precast concrete elements known, preferably heated Heidelbergisch be used without it required separate formwork between the beams.
- the Support elements On the Heidelbergisch are the Support elements, in particular the wooden beams or steel beams, with a certain Spaced apart and fixed.
- the support elements Moreover, not arranged directly on the Heidelbergisch, but of this spaced apart by spacers. These spacers can also be considered as Connecting means for anchoring the support elements serve in the concrete slab, wherein preferably dovetail-shaped recesses are provided in the beam.
- the composite element After curing of the concrete, the composite element is rotated so that the Side that formed the bottom during manufacture, that is, the immediately on the Wennisch now forms the smooth, flat top. In other words, the Now support elements turned down, while the concrete slab now the top of the Composite element forms.
- This reversal of the composite element can happen by the GmbHisch together with the cast and cured composite element is folded so that the Siemensisch is located above the composite element. In other words, the folding process takes place in the horizontal Axis about 180 °.
- the Heidelbergisch together with the Composite element is moved into the vertical, that is, it is a folding process to the axis of rotation, which lies in the horizontal, but not by 180 ° but only to 90 °.
- the composite element After setting up the switch table, the composite element is looped detected on its upper narrow side or the like and about its vertical axis rotated by 180 °. Subsequently, the composite element is now reversed on Heidelbergisch, which can then be lowered again. With both possibilities of the Turning over the composite element takes place as a last step lifting the finished Composite element from the turn horizontal Heidelbergisch. It thus remains Composite element, standing on the support elements with the smooth, flat top.
- the method described brings the advantage of an industrial manufacturing of Composite elements made of concrete and other supporting elements, in particular wooden beams or steel girders with them. It can with conventional, existing in concrete works GmbHisch be worked without an additional between the bars Cladding is needed.
- the composite elements can therefore be inexpensive in the Prefabricated part factory be prefabricated. In particular, by the omission of any Formwork activities between the beam elements are great cost savings possible. It can thus be a lightweight composite ceiling extremely cost effective and accurately with reproducible statics can be realized.
- a single or multi-layer reinforcement simply introduced can be. It is also placed on the switch table and with spacers fixed, preferably in engagement with the teeth on the wooden beams, as well then shed with concrete.
- insulating material can be used to provide additional heat or To achieve sound insulation.
- Cladding material such as plasterboard, panels or grooved and Apply spring boards.
