Definitions

  • the present invention relates to a component for thermal insulation according to the preamble of patent claim 1.
  • such components for thermal insulation in numerous variants are known; These usually consist of an insulating body made of polystyrene with reinforcing elements in the form of tensile metal rods for tensile force transmission, in the form of transverse force rods made of metal for lateral force transmission and pressure elements made of metal - or more recently concrete - for pressure force transmission.
  • the DE-A-43 00 181 proposed to provide the insulating body for securing the position of the reinforcing bars with the insulating body encompassing strips of plastic, in which the reinforcing bars could be anchored. Furthermore, was by the DE-A-196 38 538 for fixing the position of the reinforcement elements proposed to provide built-in modules, which encompassed and defined a reinforcing element in the region of the insulating body and which were arranged and fixed in adapted to the outer shape of the module recesses of the insulator.
  • the present invention seeks to further improve the components of the type mentioned in terms of their thermal insulation properties and their cost.
  • reinforcing elements are not determined by the plastic shells or plastic rails or other fixing elements used in the prior art in terms of their orientation and location in the insulator, but that the determination of a foam, in particular polyurethane or polystyrene foam can be done, which itself has optimal thermal insulation properties , are further eliminated in the structural element for thermal insulation previously existing materials with poor thermal insulation properties, so that it is possible to provide a generic device for thermal insulation, which consists only of insulating material and the reinforcing elements, but otherwise no auxiliary elements in the region of the insulating needed determine the reinforcement elements in terms of their orientation and location.
  • the variant may be energetically equivalent with prescribed outside of the insulator to individual reinforcing elements distribution bars, as well as in the region of the insulating no fixing elements must be provided, which extend through the insulating body and thus form an additional cold bridge;
  • the mentioned distribution bars have the well-known in the prior art disadvantages that they complicate, for example, the installation of the device for thermal insulation due to their collision with the on-site connection reinforcement and, of course, also to an increase in the cost of such a material Lead component for thermal insulation and finally increase significantly in certain embodiments, the transport volume of such devices.
  • the insulating body consists essentially of a foam, in particular of polyurethane foam and the reinforcing elements can be fixed by foaming in the polyurethane foam of the insulator; because then the insulator can be easily made by foaming and the reinforcing elements can then be fixed with equal, so that the insulator does not have to be first brought into shape and must be divided to insert the reinforcing elements along a parting plane with appropriate precise openings.
  • the reinforcing elements in the end position intended for them and then provide the polyurethane foam around these reinforcing elements around, so that the reinforcing elements after setting or drying of the foam positionally and accurately defined.
  • the foam can be filled into a mold which corresponds to the desired final insulating body shape;
  • the existing of foam insulator can be processed after foaming and curing or drying and cut out of him or the desired Isolierintelligenceform or be cut out.
  • a first insulating body portion as before consist of polystyrene and form a kind of mold for the polyurethane foam, so that the polyurethane foam is then not necessarily responsible for the shape of the insulator, but for the intended him down the reinforcement elements in the insulator.
  • the insulating body consists of polyurethane foam, such as from DE-A-30 05 571 as well as out DE-A-195 08 292 ,
  • the polyurethane foam parts are prefabricated, in which case the reinforcing elements are used in accordance with provided in the polyurethane foam openings;
  • the desired positional fixation can not be made available to the same extent by such existing polyurethane foam insulator with corresponding openings for inserting the reinforcing elements, so that in these components additional measures, such as setting over said distribution bars is required or was.
  • the foam is expediently a hard foam, in particular a rigid polyurethane foam and / or is closed-cell and / or diffusion-tight; Furthermore, it is expedient if-as is quite customary in the case of heat-insulating elements made of polyurethane foam-a cellular gas with low heat conductivity is provided in foam cells of the polyurethane foam, wherein the cell gas may consist in particular of a mixture of cyclopentane and carbon dioxide. Finally, it is advantageous if the polyurethane foam is provided with fillers which consist of glass, in particular of glass microballoons or of aluminum, in particular of aluminum powder.
  • the reinforcing elements may consist of pressure elements, of transverse force elements and / or traction elements.
  • the box may be composed of at least two, in particular folding, box parts and / or be formed in cardboard or the like, in a plastic, preferably polystyrene or in a metallic material, preferably in the form of a sheet metal grid or expanded metal.
  • a cardboard box is first used as an assembly aid in that the reinforcing elements are arranged in the recesses provided, e.g. be plugged in. Subsequently, the cardboard box is used as a mold, ie as a formwork element for foaming, in which case the starting material of the rigid foam, such as polystyrene or polyurethane, is introduced into the mold and foamed up after the reinforcement elements have been applied.
  • the cardboard can either be removed after curing of the foam or left on the insulator.
  • FIG. 1 a component for thermal insulation 1 is shown in side view, which has a cuboid insulating body 2, which serves in a joint between two components to be arranged, in particular between a load-bearing building ceiling and a supported, opposite the building projecting balcony plate (which are not shown in the drawing).
  • the invention can also be used in other types of reinforcing elements, for example, in printing elements, which are limited to the Isolier stressesebene and not protrude from the insulating body.
  • the reinforcement elements 3, 4 and 5 are substantially horizontal (relative to the installed state) and substantially transversely, that is in particular perpendicular to the longitudinal extent of the insulating body, so that the reinforcing elements from one to the component joint and thus adjacent to the insulating component extend through the insulating body and the component joint in the other component, thus ensuring the desired power transmission.
  • the insulating body 2 has in the installed state the task to heat-control the component joint; Typically, the Isolier Eisen, so according to the thickness of the component joint 8 to 12 cm, in low energy and passive houses now also quite up to 20 cm.
  • Another function of the insulating body 2 refers to the time before reaching the actual installation state, namely on the production of the device for thermal insulation, its transport (possibly disassembled into individual parts) on the construction site or precast plant and also on the date during the Installation and after installation to the creation of the adjacent concrete components, which are often cast in situ concrete.
  • the insulator ensures the required position, orientation and position fixation of the reinforcing elements; since the reinforcing elements must perform a certain function in the installed state, ie must absorb or transmit certain forces, it must be ensured that the reinforcing elements in the final state have their predetermined position.
  • this can be easily ensured by aligning the reinforcing elements, as it corresponds to the end position intended for them and then by using the polyurethane foam to foam not only the reinforcing elements, but at the same time to produce the insulating itself. Because in the embodiment according to FIG. 1 represents the intended for fixing the reinforcing elements 3, 4 and 5 polyurethane foam also equal to the insulating body 2.
  • FIG. 1 can be determined easily due to the minimum number of components used that such a device for thermal insulation in terms of thermal insulation properties and costs can be optimally designed.
  • FIG. 2 shows in three different subareas a), b) and c) the following:
  • FIG. 2 shown in the middle section a) shows an alternative embodiment of a device for thermal insulation 11 in front view with an insulating body 12 and reinforcing elements in the form of tie rods 3, transverse force bars 4 and push rods 5, which are designed as well as the device for thermal insulation 1 FIG. 1 and therefore have the same reference numerals.
  • the insulating body 12 is also in the device for thermal insulation 11 FIG. 2 formed cuboid, said longitudinal extension of the insulating body along the component in FIG. 2 corresponds to the plane of the drawing, so that perpendicularly extending reinforcing elements 3, 4 and 5 protrude from the plane of the drawing and therefore in FIG. 2 are shown cut with a circular cross-section.
  • Insulating body 12 is now divided along a horizontal plane 12 a into two insulating body halves 12 b, 12 c, wherein FIG. 2b ) in the upper half of FIG. 2 the upper insulating half 12b is shown and in Figure 2c ) in the lower half of FIG. 2 the lower insulating half 12c.
  • the insulating body 12 is made of polystyrene in a conventional manner and has in its upper insulating half 12 b window-like recesses 12d for receiving the tie rods 3, in its lower half Isolier restructuringhtag 12c window-like recesses 12e for receiving the transverse force rods 4 and window-like Recesses 12f for receiving the pressure rods 5 on.
  • the window-like recesses are cuboid and are filled with corresponding in the form here adapted cuboid packing 16a, 16b and 16c, said packing 16a carry the tension rods 3, the packing 16b the transverse force rods 4 and the packing 16c the pressure rods. 5
  • These packing 16a to 16c are also made FIG. 3 see where they are shown in individual drawings along with their associated reinforcing elements 3 - 5.
  • the packing 16a to 16c are made of polyurethane foam and determine their associated reinforcing elements by foaming, that is they do not require a dividing plane or similar openings through which the reinforcing elements are threaded, but they are in appropriately adapted forming tools, in the first inserted the reinforcing elements were, filled, foam around the associated reinforcement element and attach this after drying or curing form-fitting. If you are then stuck after curing or drying in the window-like recesses 12d, 12e and 12f, they provide the corresponding positional fixation of the reinforcing elements 3, 4, 5 relative to the insulating body 12 and also relative to each other.
  • the polyurethane foam with its predetermined outer shape ensures a correspondingly large contact area within the recess of the insulating body, which is naturally greater by a multiple than the peripheral region of the associated reinforcing elements and thus leads to a significantly improved positional fixation in comparison to an insulator consisting directly in polystyrene specified reinforcement element.
  • FIG. 4 shows a the element for thermal insulation 1 from FIG. 1 corresponding design of a device for thermal insulation 41, extending from the device for thermal insulation 1 FIG. 1 only differs in that the insulating body 2 made of polyurethane foam is surrounded by a box-shaped shuttering element 42 in the form of a cardboard box.
  • This cardboard box 42 serves on the one hand to hold the reinforcing bars 3, 4 and 5 before and during the foaming of the polyurethane in its predetermined position, including the cardboard box perforations for receiving and in particular for the insertion of the reinforcing elements, wherein the perforations expediently at all in Question upcoming reinforcing bar positions are provided and only those perforations are used to create openings, which should actually absorb rebars.
  • the cardboard used to limit the polyurethane to be filled into the cardboard during expansion in its expansion and to bring in the desired shape If the cardboard box is not dimensionally stable enough, it can during the foaming by (not shown in the drawing) measures such as a separate tool, a form o.ä. get supported.
  • the present invention offers the advantage, with the simplest but most effective measures, of providing an improved thermal insulation component which, on the one hand, is optimized with regard to the heat-insulating property on the one hand and the manufacturing costs on the other hand.
