  • the invention relates to a load-bearing and heat-insulating brick (1), which can be used for effective heat dissipation between a wall and a floor or floor slab.
  • the known components support columns, which are connected by intersecting and / or one-sided abutting webs.
  • the webs serve to fix the support columns in their position so as to be able to absorb the shear and shear forces in the masonry can.
  • thermally insulating, load-bearing components known, which have to achieve sufficient strength over the entire component by pulling or circumferential skeleton.
  • the skeleton comprises numerous, all together continuously connected support elements, which extend vertically from the upper to the lower end of the respective component.
  • the components known in this way have the decisive disadvantage of much too low heat decoupling between the trades built above the components and the trades built below the components.
  • the object underlying the present invention is to be in the development of a heat-insulating brick, which overcomes in particular the mentioned disadvantages of known from the acknowledged state of the art components, in its production is substantially simplified and thereby significantly improves the thermal insulation.
  • the inventor further recognized that in today's time compelling bricks must not only be used for effective heat dissipation between a wall and a floor or floor slab, but should also be suitable as a brick for the construction of load-bearing and non-load-bearing walls.
  • Such a brick is suitable for producing a heat decoupling between wall and floor or wall and ceiling as well as for the construction of masonry and thus solves the problem underlying the invention.
  • the brick according to the invention (1) thus comprises a mineral or plastic foam body as a heat insulation body (2), between the bearing surfaces are in the load direction support columns (4) whose shape, size, number and position determined depending on the required and / or desired load capacity become.
  • support columns (4) with round or triangular, four- or pentagonal horizontal cross-section, but also a combination of said cross-sectional shapes are conceivable.
  • Particularly good results could be achieved with round support columns (4) having a diameter (d) in a range of 22 mm to 32 mm at a respective axis spacing of the support columns (4) of (s).
  • the vertical support columns (4) are fixedly connected to one another by the load-bearing, preferably reinforced coatings (5) on the upper and on the lower support surface and in this way are fixed both vertically and horizontally.
  • the bearing, preferably reinforced coatings (5) which are located on the support surfaces, play a major role in the stability of the entire wall block (1) according to the invention, in particular for increasing the bending and other mechanical strengths while improving the resistance to acting forces.
  • a cement mortar, a polymer mass or a suitable mixture of both systems is suitable, for example a polymer mortar, more preferably with an embedded or mixed reinforcement, e.g. Glass mesh fabric, nonwoven, fibers or the like.
  • an embedded or mixed reinforcement e.g. Glass mesh fabric, nonwoven, fibers or the like.
  • the coating material is as waterproof as possible or water-repellent.
  • the brick (1) according to the invention consists exclusively of the heat-insulating body (2), of the heat-insulating body (2) passing through in the vertical direction of support columns (4) and of a respective coating (5) above and below the heat-insulating body (2).
  • the coatings (5) preferably provided with a reinforcement are so important for the stability of the brick (1) according to the invention, it is essential if the coatings (5) are insoluble with the support columns (4) and optionally additionally with the heat insulation body (2). are connected.
  • This compound can be implemented by gluing, scoring, fusing or by casting the material either for the support columns (4) or for the coatings (5) to the respective already completed counterpart of support columns (4) and coatings (5) without it to be limited.
  • each a supporting, preferably reinforced coating (5) is insoluble and preferably applied over the entire surface.
  • an interrupted running coating (5) is conceivable. This interrupted coating (5) can be designed in the form of random and / or deliberately designed patterns.
  • the individual coating (5) is applied directly to the respective support surface and the upper or lower ends of the support columns (4), which means that the initially liquid or pasty material for forming the individual coatings (5) on the respective support surface and the upper and lower ends of the support columns (4) is sprayed, lubricated and then dried or hardened. An additional screwing, staking, merging or other additional reinforcement of the compound of the coatings (5) with the support columns (4) is possible.
  • the coatings (5) can also be manufactured separately and adhered with a suitable adhesive to the upper or lower ends of the support columns (4) and preferably additionally to the bearing surfaces.
  • an adhesion protection coating (6) for the lateral surfaces of the brick (1) according to the invention.
  • the roughening or structuring of the surfaces of coating (5) and / or protective coating (6), for example, by applying quartz sand or grit of suitable grain size in the fresh (wet) coating composition improves the adhesion of mortar or adhesive on the respective coating (5, 6) ,
  • the heat-insulating body (2), through which the support columns (4) extend, is preferably made of plastic foam, such as e.g. (extruded) polystyrene, PU, PVC, phenolic or mineral foam, e.g. Glass or stone foam.
  • plastic foam such as e.g. (extruded) polystyrene, PU, PVC, phenolic or mineral foam, e.g. Glass or stone foam.
  • thermal insulation material mainly a low thermal insulation coefficient and the lowest possible water absorption are crucial, since the support columns (4) and their associated reinforced coating (5) absorb the forces acting.
  • the brick according to the invention (1) preferably has a flat, wide design, because here the use is particularly simple and the thermal insulation is particularly efficient. Thus, dimensions of 40 mm to 60 mm in height, lengths of 450 mm to 550 mm and widths of 80 mm to 240 mm are preferred.
  • the brick (1) according to the invention is not yet provided with the coatings (5) heat insulation body (2) at defined intervals with vertical openings (3), preferably provided with holes of suitable dimensions over the entire thickness.
  • These breakthroughs (3) are then filled with a suitable material for the preparation of the support columns (4). It is preferred if the initially liquid or pasty material for the support columns (4) in the openings (3) of the heat-insulating body (2) is entered, where then this material dries and / or hardens and so the solid support columns (4) is formed , It is also conceivable that the support columns (4) manufactured separately and then inserted into the holes (3) and glued or fused with the heat-insulating body (2).
  • the support column material itself consists of a mortar made using a hydraulic binder such as cement or gypsum or a polymer binder such as epoxy, PU, acrylate or polyester resin and one or more fillers and aggregates with or without the addition of fibers , Fleece or fabric is made.
  • a hydraulic binder such as cement or gypsum
  • a polymer binder such as epoxy, PU, acrylate or polyester resin
  • fillers and aggregates with or without the addition of fibers , Fleece or fabric is made.
  • the compressive strength of the support columns (4) is between 10 and 80 N / mm2 and the thermal conductivity between 0.1 and 1.0 W / mK. Higher mechanical strengths are generally associated with poorer thermal insulation properties, which can be controlled by the choice of binder, aggregates and mixing ratios.
  • the choice of the support column material and their area ratio depends on the mechanical strength required for the intended application. Advantageous is the choice of materials that meet the mechanical requirements and at the same time have the lowest possible thermal insulation coefficient.
  • heat-insulating brick (1) consists of a cuboid heat insulation body (2) with recessed openings (3), in the support columns (4) are entered.
  • the heat-insulating body (2) envelops the support columns (4), whose upper and lower ends, as well as the upper and lower bearing surface of the heat-insulating body (2) each with an insoluble applied, reinforced here coating (5) are connected.
  • the heat insulation body (2) should be made here of polystyrene foam XPS.
  • the support columns (4), which pull through the heat-insulating body (2) over its entire thickness should consist of mineral material, such as cement, gypsum or polymer concrete, in the present case they are made of epoxy resin concrete. They have a circumference (d) of 25 mm and a center distance (s) between adjacent support columns (4) of 65 mm.
  • the upper and lower bearing surfaces are made with a reinforced layer (5) in the present case of polymer mortar.
  • the thickness of the coating (5) is preferably between 1 and 5 mm, here 2 mm.
  • Glass mesh fabric which must be alkali-resistant when using a cement coating, has proven to be a proven reinforcement.
  • Other types of reinforcements are also conceivable.
  • the inventive illustrated, heat-insulating brick (1) has on its side walls on a protective coating (6).
  • a roughening of the coating surfaces was carried out by applying quartz sand in the still fresh, that is wet coating to improve the adhesion properties of the coatings (5, 6).
