Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing or supporting plate for a construction structure having a reinforcing web projecting from a plate plane extending through the plate at intervals in parallel with each other in the longitudinal direction, the reinforcing web being a reinforcing or supporting plate. It is formed by the bent part of the upper part. Here, at least in the freely projecting edge regions of the reinforcing web, the mutually parallel parts of the reinforcing or support plate or adjacent edge webs of the reinforcing or support plate are joined to one another.

[0002]

BACKGROUND OF THE INVENTION Known reinforcing or supporting plates (Swiss patent 644 922) are provided with reinforcing webs extending longitudinally and projecting from the plate plane, which webs are laid on top of the reinforcing or supporting plates. It is formed by a bent part. In this configuration, both of these parts forming the reinforcing web are arranged to extend parallel to each other and to be joined together. The reinforcing web, which is represented in this configuration as a fold, has at its free edge recesses which are pressed in the direction of the main plane of the plate, these recesses being designed to serve as adhesive recesses for the concrete. Producing such a reinforcing web with recesses is just as complicated. Because the striking action has to take place in the plane of the web, suitable clamping means and support structures are required in order to be able to make this deformation. In such a configuration, a sufficient fixed connection is provided between the concrete and the reinforcing or supporting plate transversely to the plane of the supporting plate. These reinforcement or support plates should, however, also be able to carry tensile or compressive stresses,
Due to the comparatively small lateral bulges formed by the recesses, no special retention is obtained in the longitudinal direction of the reinforcing web. Thus, when properly loaded, the individual depressions form a free space immediately in fresh concrete, or when properly loaded with alternating forces, thus preventing the transmission of tensile or compressive forces. There was something.

In another known embodiment (Austrian Patent No. 331 473), a reinforcing web is likewise provided. However, the freely projecting longitudinal edge region of the reinforcing web is in this case constructed as a hollow profile,
This hollow contour is designed to be better retained in concrete by suitable lateral deformation. With such a structure no substantial tensile or compressive stress is transferred between the reinforcing or support plate and the concrete. The hollow contours in the free edge regions of these reinforcing webs are correspondingly deformed by a suitably large tensile or compressive force, so that immediately a longitudinal movement between the reinforcing or supporting plate and the concrete filling can take place. Become.

[0004]

The invention is therefore based on the object of designing a reinforcing or support plate of the initially mentioned type such that it is able to carry tensile or compressive stresses in spite of its simple construction.

[0005]

According to the invention, this object is achieved in that the freely flared longitudinal edge region of the reinforcing web or edge web is shaped into a corrugation or a tooth profile.

The arrangement according to the invention ensures that tensile or compressive stresses are taken up by the reinforcing or support plate. This is because, just looking in the longitudinal direction of the reinforcing web, the joining of the large faces of the reinforcing web is provided at the concrete surrounding the reinforcing web.

Furthermore, there is the particular advantage that the manufacture of the reinforcement or support plate according to the invention or the special deformation of the reinforcement web is simple. For example, the reinforcing web in the longitudinal direction is provided by means of a device such as the following: gears are provided one behind the other, spaced apart from one another, and whose enveloping circles project from both sides in the plane passing through in the middle. Be guided. Such gears are provided by suitable engagement with a reinforcing web for conveying through the plate, while at the same time these gears can be corrugated in the free longitudinal edge region of the reinforcing web.

The reinforcing or supporting plate, for example made of sheet metal, is stretched in this corrugated region during deformation, the elongation stresses being reduced. Exactly such an arrangement allows for roll deformation, which of course guarantees a simple and thus cheap production.

Reinforcement extending through the corrugated or tooth-shaped deformed longitudinal edge region of the reinforcing web and / or the edge web and the plate plane at a distance parallel to this plane. It is particularly advantageous when grooves are provided.
As a result, an additional stabilization of the reinforcing web and / or the edge web takes place, in particular the edge webs of the two reinforcing or supporting plates which join to one another are thereby precisely aligned with one another in their height position. Will be.

Furthermore, the edge webs of the plates are designed as approximately right-angled upward bends, the opposite edge webs gripping the edge webs of the adjacent plates in their free longitudinal edge regions. It is proposed to be bent into a hook shape. This configuration makes it possible for adjacent reinforcing or support plates to be connected to one another in a frictional and / or non-frictional engagement, with the sealing means also being applicable in this gripping area.

The portion of the plate forming the reinforcing web is
It is further proposed according to the invention that the longitudinal edge regions, which are corrugated or tooth-shaped, subsequently extend to extend at an acute angle or arc with respect to the plane of the plate. In that case, a flanged part in the transition region between the part forming the stiffening web and the flat plate part projects into the channel formed under the stiffening web. By this means the possibility of mounting various installations and coatings of all kinds, i.e. the possibility of applying fixing plates, rails etc. Furthermore, the soundproofing effect of the space and the body is thereby achieved well. With such a form as the other action,
The desired haze-free optical construction results when the reinforcement or support plate is applied as a layer member to the underside of the floor.

A further proposal lies in the fact that the reinforcing web and / or the edge web are inclined at an acute angle with respect to the plane of the plate. Such an arrangement is expedient when the reinforcing web follows directly into the correspondingly formed passage, thus providing sufficient space on both sides of the reinforcing web for filling with concrete. It is expedient if at least two adjacent reinforcing webs are inclined with respect to each other.

A further proposal according to the invention is that the reinforcing web and / or the edge web are provided with holes in order to apply a retaining curve which acts as a spacer. It is therefore possible to apply retaining bends for additional stability and precise spacing, used to additionally fix inserts, iron distributors etc. before concrete-casting these bends. You can do it.

The holding curve is bent twice at approximately right angles at its two ends, the outermost bending end of the holding curve being in the plane formed by the base part of the holding curve and the first curve. There is also a particularly advantageous embodiment in that it overhangs at approximately a right angle to. The curved end is thereby ensured that it can be inserted into a hole provided in the reinforcing web and / or the edge web and is self-blocking from falling there. Therefore, the swaying vibration does not cause the slack of the holding curved portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The reinforcing or supporting plate according to the invention comprises walls, ceilings, vaults, floors and roofs, as well as struts having angular, circular and toroidal cross-sections, by means of special profile-surface equipment consisting of profiles and / or strip bands. Can also be applied to reinforce, in which case these reinforcement or support plates also serve as lost barriers, as moisture barriers, and thus also as vapor barriers, sound absorbers and fixing members for various assembly parts. Be useful. Reinforcing or supporting plates are then profiled on one or both sides of galvanized or laminated steel- or aluminum sheet, aluminum continuous casting, non-rusting sheet or any other type of sheet metal, glass or carbon fiber. Made of plastic or asbestos.

The support plate 1 is provided with stiffening webs 2 projecting from plate planes which extend longitudinally parallel to one another and are spaced apart from one another, the webs 2 being formed by members which are bent over the support plate 1. The freely projecting longitudinal edge regions 3 of the reinforcing web 2 are oriented so that the elements of the support plate 1 or the edge webs 4, 5 extending parallel to one another are joined to one another in parallel. This freely overhanging longitudinal edge region 3 of the reinforcing webs and / or the edge webs 4, 5 is deformed into a corrugated or tooth profile.

As a result, it is possible to completely bear tensile or compressive stress after the support plate 1 is attached with the concrete layer 6.

This corrugated or toothed deformation of the longitudinal edge region 3 can be produced by simple bending or pressing.

1 and 2, further reinforcing webs 2 and / or
Alternatively, it is clear that the edge webs 4, 5 are provided with holes 7 for applying holding curves 8 which act as spacers. Such a retention curve is shown in FIGS. 10 and 11.
The holding curved portion 8 is bent twice at both ends thereof, and is further bent inward by about 6 °. The outermost bent end 10 of the holding curve 8 projects substantially at right angles to the plane formed by the base part of the holding curve 8 and the first bend 9. These holding curved portions 8 serve for stabilization and for maintaining a space, and are made self-blocking by a special formation.

In the structure according to FIG. 3, the portion 11 forming the reinforcing web 2 extends following the longitudinal edge region 3 which is corrugated or tooth-shaped and extends at an acute angle to the plane of the support plate 1. ing. In that case, a flanged portion 12 in the transition region between the part 11 forming the reinforcing web 2 and the flat part of the support plate 1 projects into a passage 13 formed on the underside of the reinforcing web 2. Each web or every other reinforcing web 2 can thus be formed as shown in FIG. A similar embodiment is shown in FIG. 5, however, the part 11 of the reinforcing web 2 is formed as an arc-extending part 11.

As can be seen from FIG. 6, between the individual reinforcing webs 2 there are provided contouring members 23 which extend the intrinsic stability, which members may optionally have additional longitudinal grooves 14.
Is equipped with. Such a support plate can form a self-supporting structure and does not require a bond with concrete. In that case, it is additionally possible, for example, to apply the assembly member 24 between two mutually inclined reinforcing webs 2.

In the structure according to FIGS. 5 and 6, the reinforcing web is inclined at an acute angle with respect to the plane of the plate. The edge webs 4, 5 may likewise be arranged at an acute angle with respect to the plane of the plate. When at least two adjacent reinforcing webs 2 are inclined with respect to each other,
It is particularly advantageous, so that various assembly parts 15, 16
And the holders for 24 are obtained.

The structure according to FIG. 7 is provided with reinforcing webs 2, which are oriented parallel to one another and at a distance from each other, which is, as is apparent from FIGS. 1 and 2, actually the simplest structure. Are shown.

The structure according to FIGS. 3, 5, 6 and 7 and FIG.
In the enlarged view according to FIG. 1, the edge web 4 of the support plate 1 is formed as a bent-up portion at a substantially right angle. The facing edge web 5 comprises a hook-shaped curved portion 17 for gripping the edge web 4 of the support plate 1 adjacent to its free longitudinal edge region. A frictional engagement and a non-frictionation engagement of the support plates which follow one another is thus possible, the sealing strip or the sealing means 18 being able to be inserted into the curved portion of the edge web 5.

FIG. 8 shows an embodiment showing how the support plate 1 according to the invention is applied in a special way to stiffen all kinds of struts. The various components of the support plate can be joined together, depending on the required shape of the post. In this example, the edge webs 4 are directly joined to one another, the longitudinal edge regions 3 being corrugated or toothed being in non-frictionally meshing engagement. In such a structure between the longitudinal edge region 3 which is corrugated or toothed for additional stability and the plate plane,
Reinforcing grooves 19 are provided which extend parallel to the plane of the plate and at intervals.

In the embodiment shown, the support plate is always essentially flat. However, it is also possible to curve the supporting plate in an arc in a plane extending transversely to the reinforcing web or the edge web, so that the reinforcing or supporting plate according to the invention can be used without problems in curved construction materials. Can be done. Therefore, it is possible to bend into and out of concrete.

The seal 18 inserted between the adjacent support plates 1 is particularly preferably designed as a moisture barrier and thus as a vapor stop, and also as a dirt barrier, as a seal, and of the adjacent support plate 1. Serves as a friction-engaging connection between.

It is also possible to provide additional equipment with known steel gates. Such variants, however, are not shown in the drawing. When reinforcement or support plates are manufactured from metallic materials, the starting material is metallurgically adapted to the metallurgical purpose and is in the same position as these steel gates in stress due to expansion and extension. Placed. Reinforcement or adapting to the resistance of the support plate is made possible by the variable contour shape, the properties and thickness of the applied material and by stretching.
