Description

[0001] Element for forming a wall or roof of a building

[0002] The invention relates to an element for forming a wall or a roof of a building, comprising an outer sheet and an inner sheet and an insulating core glued to the outer sheet and the inner sheet, which insulating core consists in particular of rock wool or a polyurethane foam, wherein the outer sheet has ribs which are spaced apart by depressions and are preferably parallel.

[0003] Elements of the type mentioned above have become known from the state of the art, particularly as sandwich panels, and are usually manufactured in accordance with the standard

[0004] Manufactured in accordance with DIN EN 14509. These panels consist of an inner and an outer sheet, with an insulating material sandwiched between them as an insulating core. This allows for the rapid construction of halls, in particular, by arranging the corresponding panels on a support structure and on a roof area. The sandwich panels are waterproof and thermally insulating, so the walls and roofs of the halls can essentially be constructed exclusively from these elements.

[0005] However, it has been shown that the construction of buildings, especially halls, despite the use of such panels still involves very high effort and correspondingly high costs.

[0006] This is where the invention comes in. The object of the invention is to provide an element of the type mentioned above with which the construction of a building, in particular a hall, is possible in a particularly cost-effective and simple manner.

[0007] This object is achieved according to the invention by an element of the type mentioned at the outset, in which the inner sheet has at least one bead for receiving a plastic line for heating or cooling purposes in the region of the recesses of the outer sheet, in particular centrally between the ribs.

[0008] In the context of the invention, it was recognized that the construction of a hall, despite the use of corresponding elements, incurs high costs. These costs are due to the fact that a heating system must also be installed in the hall in order to avoid unacceptably low temperatures in the cold season, which results in high expenditure and high costs.

[0009] According to the invention, it is now possible to arrange the heating directly in the elements or sandwich panels by arranging heating lines on the elements in the grooves in the inner sheet. These lines are preferably made of plastic. However, it goes without saying that the lines arranged in the grooves and through which a heat transfer medium can be conveyed can in principle be made of any material, although the grooves are designed in particular to accommodate plastic lines. The inner sheet thus not only serves as a cover for the insulating material as before, but the grooves give it an additional thermal effect, as a heat radiating element, and also serve to accommodate the heating lines, which would otherwise have to be stored separately in the hall, hung up, or laid in the floor.

[0010] It is advantageous if at least one bead has an undercut. A heating pipe is usually formed by a plastic pipe and can thus be positioned or pressed into the bead with a force fit, namely if the bead has a smaller diameter than the heating pipe in the area of ​​the undercut. The heating pipe then presses against the bead from the inside, ensuring particularly good heat transfer between the heating pipe and the inner panel. This ensures that the inner panel has a particularly good thermal connection to the heating pipe and can thus be used for heat dissipation or heat absorption.In this way, a very large area of ​​the hall, namely usually an entire wall area as well as an area of ​​the ceiling, is achieved for heat dissipation, whereby heating of a corresponding building such as a hall is also possible with a low-temperature heating system, which has a high degree of efficiency, so that operation or heating of the hall is also possible at low cost.

[0011] It is particularly advantageous if the at least one bead has a partially circular cross-section with an opening so that a plastic line for conveying a heating or cooling medium can be introduced through the opening into the bead and rests fully against the bead in some areas. The element is therefore particularly easy to adapt to conventional plastic lines or pipes, which are usually used for underfloor heating and the like. Accordingly, the bead usually has a diameter or curvature circle with a diameter of, for example, 10 mm to 30 mm in the circular area. To prevent the lines from accidentally falling out of the beads, the openings are usually designed with a smaller diameter than the plastic lines, which also creates the undercut.

[0012] It is particularly preferred that the ribs and beads be parallel. Corresponding elements are typically screwed to a substructure in the area of ​​the ribs. The parallel arrangement of ribs and beads, with the beads positioned between the ribs, thus easily ensures that no heating pipes located in the beads can be damaged when screwing the elements to a substructure.

[0013] In addition, it has been shown that parallel arranged ribs and beads contribute to a particularly high stiffness and strength of the element, so that self-supporting elements can be achieved or large spans can be achieved.

[0014] In principle, it can be provided that fewer beads than fins are arranged in the element, thereby achieving correspondingly short heating line lengths within the element. To enable particularly good heat dissipation through the element, it is preferably provided that a bead is arranged between each two fins, particularly in the center. This also ensures the most even heating of the element possible.

[0015] Preferably, the ribs have an approximately trapezoidal cross-section and a width at a lower end of approximately 50 mm to 200 mm. Furthermore, the ribs are generally spaced apart by flat areas and are evenly distributed over a width of 1000 mm, for example, four to five ribs.

[0016] For a particularly simple arrangement of the elements on a building, it has proven effective to arrange the corrugations in a meandering pattern on the inner sheet. A single plastic duct can then be positioned in a meandering pattern on the inner sheet, thus easily achieving even and effective heat dissipation.

[0017] It is preferably provided that a plastic line for a heat transfer medium is arranged in the at least one bead.

[0018] The plastic pipe can be installed during the manufacture of the element or later on site at a construction site.

[0019] It is advantageous if the plastic line is arranged in a meandering pattern on the inner panel, essentially in a groove, and a heat transfer medium can be fed into the plastic line via a supply line and removed from the plastic line via a discharge line. The discharge line and supply line are usually arranged in corresponding positions, so that adjacent elements can also be connected in such a way that the discharge line of a first element flows into a supply line of a next element, so that the lines in the individual elements can be connected in series and / or in parallel.

[0020] A hall can thus be constructed with corresponding elements, for example in such a way that all walls and ceilings of the hall are designed with corresponding beads and plastic pipes and thus the inner sheets can be used for heat transfer, whereby even with a comparatively low flow temperature of, for example, 28 degrees, an effective heating of an entire hall can be achieved.

[0021] Several elements according to the invention can be connected to form an element arrangement. In this context, it is advantageous if the supply and discharge lines of the elements are connected to one another, so that the plastic lines of the elements are connected in series and / or in parallel.

[0022] In a building, particularly a hall, which has a load-bearing metal structure, particularly a steel structure, to which elements are attached that form walls and / or a ceiling, it is advantageous if the corresponding elements are designed according to the invention. It is then no longer necessary to install a separate heating system in the building, allowing the building to be constructed in a particularly simple and cost-effective manner.

[0023] It is advantageous if the elements are attached to supports, with a longitudinal axis of the supports being approximately normal to the longitudinal axes of the ribs and beads.

[0024] In order to achieve particularly cost-effective heating of the building, a low-temperature heating system, in particular a heat pump, is preferably provided, which is connected to plastic pipes arranged in the corrugations.

[0025] A corresponding low-temperature heating system can be implemented, for example, with an electrically operated heat pump. To operate such an electric heat pump, photovoltaic elements are preferably arranged at least partially on the outside of the elements. These photovoltaic elements are then preferably electrically connected to the heat pump, so that any energy required to heat the hall or a building in which the elements are located can be provided by the building itself. The building can, of course, also be cooled accordingly.

[0026] Typically, the elements are attached to supports near the ribs, particularly with domes and screws that extend through the elements. This ensures a stable attachment while simultaneously eliminating the risk of the screws damaging the heating pipes located between the ribs. Typically, the outer sheet is longer than the inner sheet at one end up to the next rib, allowing the outer sheet to be positioned over a rib of an adjacent element, allowing the elements to be screwed together and simultaneously to a substructure using the overlapping outer sheets. Since the beads are not located near the ribs, the pipes located in the beads cannot be damaged by the screws.

[0027] Further features, advantages, and effects of the invention will become apparent from the following exemplary embodiments. Reference is made to the drawings, which show: Figs. 1 and 2 show sections through an element according to the invention;

[0028] Fig. 3 shows a detail of an element according to the invention;

[0029] Fig. 4 shows a wall of a building with an element according to the invention;

[0030] Fig. 1 shows a section through an element according to the invention. The element is designed similarly to a sandwich panel known from the prior art and has trapezoidal ribs 4 on an outer sheet 1, which are spaced apart by shallow recesses 5 between the ribs 4. Furthermore, as also known from the prior art, an insulating core 3 is arranged between the outer sheet 1 and the inner sheet 2, which is bonded to the outer sheet 1 and the inner sheet 2.

[0031] As can be seen, the outer sheet 1 extends beyond the inner sheet 2 at a left end of the element and thus has a further rib 4. This additional rib 4 of the outer sheet 1 can be positioned on a rib 4 located on a right edge of another, adjacent and not shown element, so that the outer sheets 1 of two adjacent elements overlap and the elements in the area of ​​the overlapping outer sheets 1 can be connected to one another and to a substructure not shown here, in particular a steel girder, by screws 12 and calottes 13, as schematically indicated.

[0032] In contrast to sandwich panels known from the prior art, according to the invention, beads 6 are positioned on the inner sheet 2 between the ribs 4, which beads extend parallel to the ribs 4 and in which heating lines formed, for example, by plastic lines 8 can be arranged.

[0033] The beads 6 have an undercut, so the heating pipes must be pressed into the beads 6, ensuring a force-fitting connection between the beads 6 and the heating pipes. This, in turn, ensures favorable heat transfer from the pipes to the inner sheet 2, allowing the entire inner sheet 2 to be used as a heat transfer surface.

[0034] Fig. 2 shows the element of Fig. 1, wherein heating lines are also shown, which are arranged in the beads 6. As can be seen, in addition to the heating lines arranged in the beads 6, connecting lines are provided, which interconnect the lines arranged in the individual beads 6 and protrude from the beads 6. This enables a meandering arrangement of the heating line on the inner panel 2, so that, for example, a heat transfer medium such as water can be guided serially through all beads 6.

[0035] Fig. 3 shows the beads 6 of the inner sheet 2 in detail, including a plastic line 8 arranged therein. As shown, the beads 6 have an undercut 14, reliably preventing the plastic lines 8 from accidentally falling out. Thus, the opening 7, through which the plastic line 8 can be inserted into the bead 6, has a smaller cross-section than the diameter of the pipe, so that the plastic pipe must be elastically deformed to be inserted into the bead 6.

[0036] Furthermore, the undercut 14 and the cross-section of the bead 6 corresponding to the plastic lines 8, which is circular over a large area, result in very good surface contact between the plastic line 8 and the inner sheet 2, so that good heat transfer is ensured.

[0037] Fig. 4 shows an interior view of part of a building, namely a wall, which part has a load-bearing steel structure with horizontally and vertically arranged supports 11, wherein elements designed according to the invention are positioned on the supports 11. The elements are connected to the supports 11 via calottes 13 and screws 12, which penetrate the elements in the region of the ribs 4, so that the elements are pressed onto the horizontally arranged supports 11. Since the beads 6, in which the heating pipes are arranged, are each positioned between the ribs 4, damage to these heating pipes by the screws 12 with which the elements are fastened to the supports 11 is ruled out.

[0038] Fig. 4 also shows supply line 9 and outlet line 10 for the heating line in the element. Corresponding supply lines 9 and outlet lines 10 from several elements can be easily coupled in order to conduct water serially through all the elements of a building. To heat or cool the building, the supply line 9 to a first element is usually connected to a flow line of a corresponding heating system, preferably a heat pump, and an outlet line 10 of a last element is connected to a return line of a corresponding heating system. Due to the significantly larger surface area compared to conventional heaters, which can basically extend over the entire interior surface of a hall, a particularly good heat transfer is achieved, so that a corresponding building can be heated with a particularly low temperature medium in the flow line. Usually, on the outside of the elements orPhotovoltaic elements are also positioned on the roof and walls of a corresponding hall, which can supply electricity for the heat pump.

[0039] An element according to the invention enables a particularly cost-effective and simple construction of a building, such as a hall. In particular, heating pipes can be arranged in the grooves 6, thus eliminating the need for a separate heating system.
