Plate, in particular floor or ceiling panel for a building -

The invention relates to a plate, in particular floor or -.

Ceiling panel for a building, with a prestressed concrete slab and at least one profile part having a web and at least one embedded therein for support flange.

Such plates are placed in the building industry prefabricated and on support on foundations, supports or load bearing walls, floor or the like wherein a system subsequently laid on the carrier profile. The use of prestressed concrete slabs, which are commonly described as prestressed concrete plates, has the advantage, that the capacity of the plates or at a lower plate thickness.

Construction height and thus weight is equal to or higher, which has an effect not only on the weight of the positive plate itself, but also the overall structure or the total weight of the building.

Another central element of the invention are the profile carrier plate, which are concreted into the prestressed concrete plate with its web, and which simultaneously serve as supports for the system floor or corresponding system floor elements. This profile on the one hand and on the other hand serve as a support for the carrier floor system in conjunction with the concrete slab to, increase the strength of the platte', wherein it is undesirable however, the bias of the prestressed concrete slab into the structural members or the biasing forces in the steel to besiege initiate.

The invention is therefore on the problem, to solve this problem.

This problem is solved in a plate of the aforementioned type in, that the web in its longitudinal direction at least in sections aligned transversely to the longitudinal direction has a profiling.

The carrier used in the invention are known in the art profile itself and be described as corrugated web carrier, wherein the corrugated web serves to substantially but in the known carriers, to increase the buckling of the web. In the invention this profiling is used however, the top flange or flange and at the same time stabilize the profile member longitudinally of the biased into the web tension or pressure forces introduced to compensate for concrete slab -, since the web similar to these forces' wTe~'"~~m'eirrrtenBaXgproblemlo" s " ** FP ciurcfr' fmanderufig ' can compensate, without them in the top chord or initiate flange.

The invention is preferably uniaxially stretched plate only, e.g. by in-situ concrete additions can be fed but also a two-axis bearing function.

The profiling in the invention must extend the entire length of the carrier profile, although this is preferred. The profiling can have various forms, for example a waveform, trapezoidal shape or the like.

Although it is possible in principle, that the profile does not extend to the prestressed concrete slab, it is preferably from load both technical and manufacturing technical reasons, when the entire web has a continuous profile.

To permit sufficient anchoring the profile support in the concrete slab, is particularly preferably in the invention, if the pressure in the concrete slab of the web connecting means for improved anchoring of the web accommodated portions are arranged in the region in the concrete slab. These connecting means can for example be for longitudinal or transverse reinforcing elements extending from the web, either the integrally, for example by welding, or positively, for example through corresponding holes in the web, are joined thereto.

Alternatively it would be possible for example, crimp the longitudinal edge of the web portions, received in the concrete slab,, to provide a corresponding pull-out fuse.

To facilitate the laying installation lines not only between the section beams longitudinally, but also transversely thereto, recesses can be provided in the webs, which are arranged outside or above the concrete slab, which can be placed by the plumbing pipes. The recesses can in principle take any form, but are preferably right angular, trapezoidal or circular. The recesses may also extend into the concrete slab in the concrete slab and in particular for received edge of the web be open towards, which simplifies the production of the recesses.

In the invention the flange and the web are preferably composed of different parts, which are welded together, as this offers the possibility, for both the flange and the web of weight and strength and then connect together to optimize welding, for example.

The section beams can be placed on a floor system, the entire area of the invention or only over portions which extends above said plate. Preferably when the width of the floor system elements corresponds substantially to the distance between two support profile and the length of the plate substantially as this size, at most twice the width, is, . The advantage of this dimensioning lies, floor elements during installation work that the system can be removed and placed in a simple manner again.

To achieve a sound insulation between the system ground and the structural members or the concrete slab floor elements or the system, between the flanges and the system or the system can bottom floor elements, are as is known, placed damping elements. In the invention are advantageously in the abovementioned dimensioning the system floor elements required only discrete damping elements, which only in the region of the abutting corners of the floor system elements must be present, which compared to walk and the fabric ""~~s ends by damping uhgseTemehterspärnis '"' ore I in s LZ ' can be.

Additionally can at the points, at which the damping elements are arranged, also inserted or spacer elements.

height-adjustable adjusting elements are used, if this is necessary or desirable level setting the system floor elements.

Further preferred embodiments of the invention are subject of the remaining subordinate claims.

Further features and advantages result from the following description of a preferred embodiment of the invention with reference to the drawings attached.

Figure. 5 a detail of FIG. 4 in an enlarged section and

Figure. 6 a plan view of the embodiment of FIG. 4.

Figure. 1 a plate 1 according to the invention, which consists essentially of a prestressed concrete slab or 2 shows.

Prestressed concrete plate constructed and section beams is 3, in the shown embodiment four beams 3 are provided wherein. Of course more or less are beams inögTicH', face weaving: the bozonplazfe: for example embodiment a width of 2.4 m and n of the dargesze 11en a distance of 60 cm 3 the structural members from each other. The length of the concrete slab is arbitrary and can be for example 2 as far as technically possible up to 8m 16m or long. Since the establishment of a prestressed concrete plate is basically known to those skilled in, this is not described in detail. For the same reason the clamping elements or the reinforcement of the concrete slab 2 are also shown not.

The profiled carrier 3 in the shown embodiment are substantially T-profiles with a web and a flange of 5th 4 has a profile on the web 4, the, for example as in Figure. 5 represented, can be corrugated, wherein the profiling of the profiled carrier 3 extends transversely to the longitudinal extent, also as shown in Figure. 2 the delineated lines 6 can be removed. Other profile forms trapezoidal wave shape as, for example, are also possible. The profiled carrier 3 are preferably made of steel, but can also be made of other materials or composites.

The Figure. 2 is an enlarged side view of a portion of a profile support 3. In this embodiment the web 4 has trapezoidal recesses 7, said recesses 7 are arranged, that it partly above the concrete slab 2 or outside the edge of the web 4 and 8 are opened, so that the recesses 7 into the concrete slab 2 extend. In the remaining 9 also trapezoidal sections, which are received in the concrete slab 2, openings 10 are mounted. 10 can be inserted through these openings connecting means, which for example reinforcing elements, pins, bolts or the like can be head, when necessary with the welded integral web 4 which can, for example, be. Additionally or alternatively can be provided further connecting means, for example longitudinally of the profiled carrier 3 which he St. stretching end ^ rods, for ' beTspTeldus "gate steel", " can be, integral with the portions 9, for example welded, are. The length of these bars may be relatively short, but can also correspond to the length of the profile carrier 3.

Finally it would be possible for example, the edge 8 or at least portions thereof, for example in the form of free cut tabs, crimp, also causing a good anchoring of the profiled carrier 3 in the concrete slab 2. It goes without saying, that the profile carrier 3 can be also included in the concrete slab without connecting means 2.

If, as described above, provided recesses 7, is the possibility of a simple, both in the longitudinal and transverse beams 3 to laying these plumbing pipes. Since the effect of the corrugated webs of the invention 4 is, voltages from the concrete slab as possible into the profile carrier not initiate 2 3 and in particular its flange 5 the recesses 7 have, not only any negative effect, but additionally support this function.

In Figure. 3 is represented, as two plates at their longitudinal edges the invention 1 11, 12 can be installed contiguous, wherein the space between these elements 13 on the section beams spanning floor system 3 are placed. The system floor elements 13 may be prepared as known per se from the state of the technique and consisting of e.g. lightweight concrete. To produce a sound insulation between the system floor elements 13 and the structural members 3, damping elements 14 are provided. These damping elements 14 can extend the entire length of the support profile 3. Alternatively and preferably the invention is however, if discrete damping elements 14 are used, which are arranged spaced apart on the flanges 5 at defined distances, this allowing to save material.

Although it "" "" the CIE Ξ fTInHuncf possible ": is SR, 'that' In stelIe" single engine floor elements are used with trapezoidal plates 13 e.g. greater screed, which considerably larger portions or the entire surface of the cover plate 1, preferably in the invention are floor system elements 13, which approximately equal to as long as broad, therefore are substantially square.

It is of course possible, to also use a system floor elements 13, which are shorter or longer than their width (for example the distance between two profiled carriers 3 and their length is an integer multiple of the width in particular.

The advantage of the preferred dimension of the system as described above floor elements 13 lies in the simple handling during the installation and also in its simple removability, existing or new installations when a access to relocation is necessary in the space below the floor system elements 13. The discrete damping elements 14 are preferably arranged in the corner regions of the system floor elements 13, wherein all adjacent floor system on a single damping element 14 or 15 adjusting element 13 elements rest.

In Figure. 4 and 5 is shown an embodiment of the invention, in addition to the damping elements 14 used in the adjusting elements 15, which are placed on the damping elements 14. These adjusting elements are in the shown embodiment 15 16 17 with a threaded rod from a foot plate, a sleeve 18 is screwed on. At the base end 16 adjacent the sleeve 18 has a flange 19, on which a plate 20 is supported. By rotating the sleeve 18' relative to the threaded rod 17 can be changed over the foot plate 20 the height of the plate 16, whereby the height of the plate members 13 relative to the flange 5 and thus the bottom plate 2 can be varied.
