Description

The invention relates to a sheet-like component for ceilings or roofs according to the preamble of claim 1. Furthermore, the invention relates to a construction for ceilings or roofs with at least one such component. Finally, the invention relates to a method for producing a component for ceilings or roofs.

For a long time known and in use are so-called Hourdisdecken. This is a ceiling construction with longitudinally extending beams, between which plate-shaped brick or concrete elements are suspended. In practice, brick-based fillers have been found to be relatively expensive and difficult to procure. Another disadvantage is that the production of surface elements with complicated profile contours is relatively expensive. Another disadvantage is that brick elements are relatively heavy and have rather unfavorable thermal insulation properties.

A generic similar component is from the CH 667 123 A5 known. The component is designed as a ceiling plate. It contains longitudinal girders made of reinforced concrete. Further, it contains hollow stones made of concrete or fired clay as filling elements. The hollow stones are lined up at intervals, with the individual carriers being located between the hollow stones. The beams are provided with reinforcements, which are covered with concrete. One disadvantage of this arrangement is, inter alia, that such hollow stones are relatively difficult to produce and unfavorable in the procurement. Another disadvantage is that in the Only hollow stones with relatively small dimensions are available.

Next describes the EP 1 180 563 a method for producing upper formwork beams, which consist of styrofoam elements, in which prestressed concrete beams are embedded. An insulated construction panel of foamed material provided with reinforcements is also in the GB 2 180 861 described. The FR 2 432 578 also describes a prefabricated component with thermal insulation elements, which are arranged side by side on a base plate, wherein the spaces are filled with concrete. Finally, the describes GB 1 540 575 a ceiling or floor element having a channel-like shaped element of wood wool, the channel being filled with a reinforced support.

The known components all have the disadvantage that they are only suitable for limited spans. The longitudinal beams embedded in the insulation material are not connected to one another at the side, so that under load they tend to twist or break away laterally. The insulating material located between them can not absorb such forces, whereby the load capacity of a construction can be significantly weakened.

It is therefore an object of the present invention to avoid the disadvantages of the known and in particular to provide a flat component for ceilings or roofs of the type mentioned, which can be produced easily and inexpensively. Furthermore, the component should be characterized by good thermal insulation properties. Finally, a versatile usability should be ensured. Yet another object is also to improve the transverse stability of the component, without incurring higher costs or the manufacturing process gets complicated. According to the invention, these objects are achieved with a component having the features of claim 1.

The heat-insulating hollow body may be a completely or only partially closed hollow body. A completely closed hollow body may be e.g. be blow-molded plastic component with a single cavity. In this way, it is easy to produce large and, above all, thick filling elements, which at the same time are characterized by their low weight. The plastic component may be made of PVC or another thermoplastic polymer.

The use of insulating materials causes thanks to its low thermal conductivity, inter alia, a good thermal insulation of the inventive component. In addition, insulating materials also have sound-absorbing and impact sound insulating properties. As insulating materials, for example, materials with a thermal conductivity (so-called. Λ value) of a maximum of 0.1 W / mK come into question. As organic materials are, for example, wood-based materials or cork in question. Advantages can also result from the use of plastics. Particularly advantageously, the filling element consist of a rigid insulating material, with which a molded body can be produced.

Evidently, the cross member extending transversely to the longitudinal direction stabilizes the longitudinal members, which are preferably arranged in parallel with one another, so that the longitudinal members are held in the relative position in which they can absorb the greatest load. A turning out of the side members about its own axis or a lateral bending of the side members is so reliably prevented. The arrangement of the transverse groove is easy to handle manufacturing technology and also the process for the manufacture of the component is not complicated by the integration of the cross member.

The cross member may be arranged within a filling element in a worked out of the filling element, for example, U-shaped or V-shaped groove. The groove can also be arranged on the transverse side of a single filling element. It is advantageous if the component has at least two adjoining each other in the longitudinal direction filling elements and when the cross member is received in a transverse groove which is formed by the transverse end sides of the abutting filling elements.

In a preferred embodiment, the filling element consists of a foam of a polymer. It may be particularly advantageous if the filling element consists of polystyrene foam. This foam material is known to those skilled in the abbreviation "EPS". The use of EPS has several advantages. The material is relatively inexpensive and manufactured components are easy to produce. This insulating material has a thermal conductivity of about 0.035 - 0.04 W / mK. Furthermore, even complex shaped body shapes for the filling element can be achieved in a simple manner. Another advantage is that because of the low specific gravity of EPS, the weight of ceilings or roofs can be reduced.

The filling element comprises, for predetermining the carrier, a longitudinal, groove-like depression which is at least partially filled with the carrier material. As a carrier material is, inter alia, concrete. With this arrangement, a self-supporting structure for the sheet-like component can be created, which is integrated in an advantageous manner in the filling element.

For use in a ceiling with at least two filling elements, it may be advantageous if the stop area of lined-up filling elements is more or less gap-free. This can be achieved in that the corresponding end faces of the adjacent filling elements extend vertically to a base surface. Alternatively, however, it is also conceivable for a component comprising at least two lined-up filling elements that between the filling elements a receiving space open against an upper side is arranged, which is at least partially filled with the carrier material. Such a receiving space can be achieved in a simple manner by appropriate shaping of the end walls of the filling elements. The previously mentioned groove-like depressions therefore do not have to be used in all fields of application. Of course, it is also conceivable, for certain applications, to combine these receiving spaces with the groove-like depressions. The receiving spaces open towards the upper side can evidently extend both in the longitudinal direction and in the transverse direction of an element and, if necessary, they can also be provided with reinforcements, as will be described below.

It may be advantageous if the filling element is designed as a one-piece solid body profile. Such a configuration is particularly advantageous when using EPS as filler material. Such filling elements are characterized by a low weight, without cavities in the filling element for weight and material reduction must be provided, of course, created by the foaming micro voids in the polystyrene foam not understood here as cavities become. This solid profile has advantageous static properties.

The recess may have a filling area extending from the top side and a bottom area adjoining the bottom area, wherein a taper is arranged between the filling area and the floor area. This arrangement ensures that the carrier or side members are stably fixed in the filling element.

It can be advantageous if the depression has side wall sections, wherein in each case at least one side wall section is assigned to the bottom region, the taper and the filling region. In this case, adjacent side wall sections can form longitudinally extending corners. With this angular configuration, the fixation of the carrier in the filling element can be further optimized.

An advantageous self-supporting structure can be achieved if in the bottom area and / or in the filling area longitudinally extending, preferably prestressed stabilizing means are arranged, which are embedded in the carrier material. As a stabilizing agent in particular reinforcing bars come into question. Of course, could also be used on wire-based stabilizers or, for example, carbon fibers.

In the recess, at least one U-shaped bracket part can be embedded in the carrier material. The U-shaped end of the bracket part may protrude from the predetermined by the top of the filling element level and exposed for detecting and transporting. The bracket can - equal or similar to the reinforcing bars - made of steel.

It can be particularly advantageous if the bow part has two approximately parallel arms, between which a filling area associated stabilizing agent, in particular one (or at most several) reinforcing iron, is carried out.

The filling element may have end faces extending in a longitudinal direction, wherein one of the end faces has a protrusion and the end face opposite thereto has a complementary recess for receiving a protrusion of an adjacent filling element approximately positively. This longitudinal direction can be predetermined by the groove-like depression. This embodiment has the advantage that filling elements can be lined up more or less accurately to one another.

The filling element may have end faces extending transversely to the longitudinal direction, wherein at least one of the transversely extending end face is configured step-like and have a step arranged in the region of the underside with a step wall section and an end wall section set back in the longitudinal direction relative to the step wall section. The step wall portion and the end wall portion may extend, for example, in a vertical plane to the base or ground level.

The step may have a groove-like, longitudinal recess which merges into the recess. With such an arrangement, the statics can be further improved.

In the groove-like depressions, a plurality of U-shaped strap parts may be embedded in the carrier material, the ends of which are opposite the plane predetermined by the upper side of the strap element protrude. At these ends, the prefabricated elements can be lifted out of the mold after the filling material has hardened. On the upper side, however, it is also possible to arrange a covering layer, which preferably consists of the carrier material. The ends of the strap parts are completely embedded in the cover layer in such a case and not visible from the outside. If the cover layer is already applied during the production of the elements, the casting of the longitudinal members or the cross member and the cover layer takes place in one operation. To lift out the elements, threaded sleeves can then be embedded in the cover layer, for example. Alternatively, however, the cover layer can also be mounted on the construction site, which is the case for example in the production of floors.

Another aspect of the invention relates to a construction for ceilings or roofs with at least one previously described component. The ceiling or roof structures contains a plurality of U-shaped, embedded in the carrier material strap parts, wherein on the upper side a layer of concrete is arranged, which covers the U-shaped ends of the strap parts.

The temple parts may be arranged in the transverse direction of rows. The strap parts of the same row can be connected to each other via a stabilizing means, in particular via a reinforcing iron, which is performed by the U-shaped ends of the strap parts.

It can also be advantageous if an end face of a component is supported or supported on a support and if a shuttering is arranged at a distance from the front end. Through the casing can be carried out in the longitudinal direction, preferably biased stabilizing agent, in particular reinforcing iron. For a ceiling construction may be advantageous if it has such casings.

For a roof construction, it may be advantageous if the filling element and the corresponding carriers are delimited at one side edge and the over-concrete layer projects beyond the side edge for forming a roof projection.

On a component for a roof construction, the covering layer may project beyond the filling element on at least one longitudinal end side and / or on a transverse end side to form a roof projection.

Finally, it is advantageous if at least one adjacent to the filling element end portion is arranged, which consists of the carrier material and which is integrally connected to the longitudinal members, wherein on the underside of the end portion preferably a heat-insulating support member is arranged. Such a component is on its underside apparent heat moderately optimally insulated and indeed in the region of its support at the ends.

Particularly advantageously, the cross member has a smaller cross section than the side members, wherein the cross member is preferably rectangular in cross section and has a smaller width than height. Such a vertically arranged cross member can absorb high bending loads. Nevertheless, he does not need to have the same cross-sectional configuration as the side members, so that ultimately filling material can be saved.

Finally, a further aspect of the invention relates to a method for producing a component for ceilings or roofs. The Method is characterized by the following steps: foaming a polymer for a filling element consisting of a foam; Providing the filling element on a flat work support; pouring a curable carrier material, in particular of concrete into at least one longitudinally extending, groove-like depression on the upper side of the filling element and / or pouring the carrier material into a filling element, which is open against an upper side and located between two juxtaposed filling elements, by corresponding shaping of the respective side Filling elements created, running in the longitudinal direction of the receiving space.

Procedural advantages can be further achieved if at least one U-shaped bracket part is inserted into the not yet hardened carrier material only so far that the U-shaped end of the bracket part protrudes from the predetermined by the top of the filling element level and exposed for detecting and transporting , Such prepared components can be easily manufactured. These components can be placed on the construction site for creating roofs or ceilings in a simple manner at the intended places, whereupon the factory exposed the ironing parts can be covered with concrete.

Evidently, the method can also be optimized with filling elements that do not consist of a foamed material such as pressed wood wool or the like. The individual filling elements are placed on a specific length on a work pad and pushed together. The open end faces of the longitudinal grooves and the transverse grooves would have to be delimited or switched off accordingly and the corresponding reinforcements must be inserted and tensioned. Subsequently, the pouring of the filling material is carried out continuously progressively over the entire length. For this purpose, for example, a crane runway can be arranged above the work support.

FIG. 1 shows a designated area 1 surface component for ceilings or roofs. The component 1 contains four interconnected surface elements, wherein a first pair of surface elements with 2 and 2a, and a pair of surface elements attached thereto are designated 2 'and 2'a. The filling element 2 described in more detail below consists of a polystyrene foam (EPS). Different trade names are used for this material depending on the producer (instead of many eg "Styropor®"). The carrier or side members 3 extending in a longitudinal direction provide and support a self-supporting structure for the component made of reinforced or otherwise stabilized concrete. For a better understanding of the respective directions is in FIG. 1 a Cartesian coordinate system indicated (see arrows x, y, z). Like the carriers 3, the stabilizing means denoted by 5 also extend in the x-direction. Transverse thereto, ie in the y-direction, rows of ironing elements 8 are arranged. By the ironing elements 8 is in each case a reinforcing iron (or other stabilizing agent) 6 performed. With O or U, the top or bottom of the component are designated. The top O of the filling elements superior parts are covered by a cover layer 30 of concrete.

Each of the individual filling elements has three groove-like depressions 4, which run parallel to one another, in which the longitudinal members 3 extend. In the FIG. 1 are in the filler 2, the side members already poured and introduced the reinforcing bars 5, while the filler 2 'no carrier material was introduced. The ironing parts 8 indicated there can thus be introduced, as is apparent, only after the filling process.

In the joint area between the two filling elements 2 and 2a is just the front side of a cross member 50 visible. Further cross members could also extend within a single filling element, as indicated for example by the cross member 50 '.

FIG. 1a basically shows the same situation as FIG. 1 , Here, however, an upwardly open receiving space for receiving a cross member is formed not only by the longitudinally abutting filling elements, but also by the transversely adjacent laterally adjacent filling elements. These are designed so that in the concerned Stossbereich an upwardly open receiving space 52 is formed, which extends only over a small part of the total height (z-direction) of a filling element. This receiving space can be reinforced with a reinforcing iron 5 'to accommodate a prestressed additional longitudinal member 53. This additional longitudinal beam stabilizes the joint area of adjacent filling elements in the longitudinal direction.

How out FIG. 2 shows, the filling element 2 is designed as a plate-like component. The existing of EPS, designed as a one-piece solid profile filler 2 has three mutually parallel recesses 4. EPS is particularly suitable due to its low specific weight, ease of molding and sufficient static properties for the present purpose. Of course, it would also be conceivable that the filling element could consist of another, for example, organic and / or polymeric material. In the wells 4 of this rigid molded body from the top O ago a corresponding support material 7 (eg, just concrete) are filled. The filling process is indicated by an arrow. With 34 then a work document is indicated, on which the bottom U predetermining bottom of the filling element 2 rests. Furthermore, in FIG. 2 clearly recognizable that one of the end faces has a step 26 in the region of the bottom U. The groove-like depression 4 extending in the x-direction contains a taper and is further configured angularly (see further below) Fig. 5 ).

The step 26 on the transverse end face 24 has a step wall section 27 and a front wall section 28 parallel thereto but offset back. The opposite transverse end face 25, however, runs continuously over the entire height of the filling element, so that in each case one step wall section 27 Transverse end face 24 abuts the transverse end face 25 of an adjacent filling element. The height of the step 26 is chosen so that a single filling element still has sufficient stability in itself and also that an adequate thermal insulation is achieved with respect to the longitudinal beams and cross members.

Out FIG. 2 is also apparent that a longitudinal end face 20 is provided with a survey 22 and the adjacent longitudinal end face 21 with a complementary recess 23. This results in the side abut a tongue and groove joint. In addition, also the longitudinally arranged recesses 29 are visible, which also extend over the step 26.

The filling elements 2 are formed in a plan view, for example, approximately square with a side length of about 1.2 m. The height is an example of about 0.2 m. The height of the step (z-direction) is 0.06 m, whereby the groove depth in this area is 0.01 m (cf. Fig. 6 ). Of course, other dimensions are conceivable.

After pouring concrete into the wells bracket parts 8 are introduced into the not yet cured concrete material. Such a prefabricated component is in FIG. 3 represented and designated there by 1 '. It can be seen that the U-shaped ends 9 of the bow parts 8 are exposed. In this way it is ensured that the prefabricated component 1 'can be easily transported, for example by means of a crane.

Out FIG. 3 It can also be seen that reinforcing bars 5 can extend through the stirrup elements 8 both in the bottom area of a groove-like depression and in the upper area. Evidently, these reinforcing bars run in the longitudinal direction x. The transverse reinforcing bars 6 are obviously above the upper level of a filling element 2 and they also preferably extend through the U-shaped bracket parts 8. To accommodate reinforcing bars in the longitudinal and transverse direction, the strap parts must at most obliquely to the longitudinal direction or to the transverse direction be used. FIG. 3 again schematically shows the work pad 34th

FIG. 4 shows a possible structural design of the bracket parts 8. At the parallel bracket arms 10 close each approximately at right angles to projecting ends, whereby an optimal fixation of the bracket parts 8 is ensured in the carrier material.

Out FIG. 5 Details on the exact shaping of a depression 4 in a filling element can be seen. The recess 4 has an outgoing from the top O filling area 11 and an adjoining, directed against the bottom U bottom portion 12, wherein between the filling area 11 and bottom portion 12, the taper 13 is arranged. The recess 4 has side wall sections 14, 15, 16, 17 and 18, wherein the side wall sections 17 and 18 and a bottom wall section 19, the taper 13 of the side wall section 16 and the filling section 11 are associated with the side wall sections 14 and 15, respectively. Adjacent side wall sections form in the longitudinal direction x extending corners.

The cross-sectional profile of the recess 4 is chosen so that the longitudinal member received therein has optimal static properties. As shown, the width b3 in the bottom region 12 is significantly smaller than the width b1 in the filling region 11, preferably less than half as wide. In contrast, the width is b2 in the tapering region 13 only slightly smaller than the width b3 in the bottom region, because only a sufficient anchoring of the longitudinal member in the filling element has to be achieved here. The width b1 can be for example about 16 cm and the width b3 about 8 cm. The width b2 is then about 6 cm. The height h of the depression can be about 15 cm.

In the FIGS. 6 and 7 Further details of the component 1 can be seen. The step 26 includes three groove-like, longitudinally extending recesses 29 which merge into the wells 4 (not shown) for the carriers ( FIG. 6 ). Incidentally, the step 26 need not necessarily be integrally connected to the filling element. It would be readily conceivable that the step 26 is a separate, approximately in cross-section prismatic bar, which is inserted between two filling elements, so that a total of an upwardly open receiving space to form a transverse groove or for receiving the cross member is formed. Such a bar is indicated by dash-dotted lines.

FIG. 7 shows a section through a finished component 1, as it is installed, for example, for a ceiling. Compared to the prefabricated component according to FIG. 3 has this element on the top O in addition to a layer of concrete overlay 30, which covers the U-shaped ends of the bracket parts 8. The underside U is formed by the filling element 3. The underside could be covered with a (not shown) plaster layer (eg plaster layer) or a plasterboard. Thanks to the porous structure of EPS, the applied plaster or a glued or glued plasterboard adheres particularly well. Of course, the bottom could also be painted. 41 denotes an upper reinforcement which is network or lattice-like (see Fig. 1 ). The filling element 2 has in Longitudinal x extending, vertical to the ground plane extending end faces 20 and 21. Evidently, the end faces 20 a survey 22 and the opposite end face 21 a complementary recess 23 for approximately positive reception of a survey of an adjacent filling element.

FIG. 8 shows the production of a ceiling construction using the inventive components. With 2 and 2a, two spaced apart filling elements are designated. An end face of a component 1 is supported on a support. At a distance from the front end of a casing 38 is arranged, are performed by the longitudinally extending, prestressed reinforcing bars 5, 5 '. Each end side close to the filling elements 2 and 2a decoupling plates 35, 35 '. These decoupling plates or support elements form the supports and consist of a heat-insulated, non-combustible material (eg of aerated concrete). The arrangements are each closed laterally by formworks 38, wherein the intermediate space between them is closed by a cover 37 and filled by a shuttering element 36. This cover 37 is intended to prevent the inflow of concrete during the subsequent concreting process. Concrete is poured into the area designated 39. This support region can also be referred to as a front section, which is integrally connected to the longitudinal members. Evidently, components can also be provided individually with such end portions 39 or with decoupling plates 35, 35 'during their manufacture.

According to an alternative variant, not shown in the drawing, it would also be conceivable in certain cases to omit the casing 38 and the intermediate space formed thereby and insert in their place a double support made of a thermally insulating material. In such a case, it would be apparent that the end portion over the double support is cast together and integrally with the side members or with the cross members. Subsequently, the double support would be severed together with the end portion. Of course, reinforcements 5, 5 'would also be inserted in this variant. The advantage of this variant is that the cost of the casing and the space required for this can be saved. The subsequent cutting of the double edition represents only a small additional effort.

The FIGS. 9 and 10 show a particular embodiment of the component in the roof design. The filling element 2 and the corresponding supports 3 are bounded on one side edge and the concrete layer 30 projects beyond the side edge to form a roof projection 33. As can be seen from the two figures, with the aid of the filling element 2 and a specially designed concrete slab 40 on the upper side, a simple Way a roof projection 33 are created. The concrete slab 40 is evidently integrally connected to the overburden and can be made in one operation during the pouring of the overburden. Of course, the cover layer or the concrete slab project beyond a component on both a longitudinal side, as well as on a transverse side.

FIG. 11 shows a plan view of a longitudinal side of two adjoining filling elements 2 and 2a, in reality, only the step 26 of the filling element 2a abuts the filling element 2. In the transverse groove 51 thus formed, the cross member 50 is arranged. The survey 22 is continued at the end face of the cross member 50. The same naturally also applies to the complementary depression 23.

In FIG. 12 It is shown how a longitudinal member 3 intersects with a cross member 50 and is formed integrally therewith. The intersection 54 is made visible by breaking away a portion of the filling element 2. The cross member 50 may have approximately the same height as the longitudinal member 3, but its cross section is significantly lower. Since the cross member 50 does not have to carry the main load, they may be formed approximately rectangular in cross-section with a height which is greater than the width.
