Definitions

  • the invention relates to a molded part made of a hard foam, which is provided with two sets of parallel cuts.
  • Hard foam plastics e.g. based on polystyrene particle foam
  • roof sealing sheets are glued to the foam panels; for facade insulation, the panels are covered with a firmly adhering plaster. Mistake. Due to the shrinkage and / or thermal contraction of the rigid foam sheets, strong tensile forces are formed in both main directions in the plane of the board when deformation is prevented in the plane of the board. These are transferred to the cover layers, which are connected to the surface of the panel in a shear-resistant manner, and there lead to stresses that occur concentrated over the butt joints of the panels.
  • the invention was based on the object of largely reducing the forces exerted by the foam sheets as a result of shrinkage and thermal change in length on the overall composite and in particular on the cover layer, but without adversely affecting the other properties, in particular the thermal insulation and the compressive rigidity perpendicular to the board level will.
  • This object is achieved in that the plate in parallel on at least one side with two coulters incision running perpendicular to the plate plane, the depth of the incisions is greater than half the plate thickness, the distances between the incisions are between 3 and 30 cm and the two coulters are orthogonal or at an angle of 75 ° to each other.
  • DE-OS 27 08 164 a rollable thermal insulation sheet is described, which consists of an insulating layer made of foamed plastic material with transverse incisions, which is glued to a cover sheet. If such a thermal insulation sheet is used to insulate flat roofs, the tensile forces described above no longer occur perpendicular to the cutting plane, but still parallel to the cutting direction and can lead to the formation of cracks over the longitudinal joints of the cover layers.
  • the stiffness and strength of the foam boards perpendicular to the board level is not changed by the cut grid, so that e.g. the walkability of the boards is not impaired.
  • the deposition time required for foam sheets can be reduced to a few days or can be eliminated entirely.
  • Preferred hard foams are those based on polystyrene, in particular flame-retardant polystyrene particle foam.
  • Extruded polystyrene foam, polyvinyl chloride foam and hard-set polyurethane foam are also suitable, as are thermoset foams based on condensation products of urea, melamine or phenols with formaldehyde.
  • the thickness of the foams is between 10 and 100 g / l, preferably between 10 and 50 g / l.
  • the thickness of the plates can be between 2 and 30, preferably between 3 and 20 cm.
  • the panels are preferably provided with the cutting grids on only one side, specifically on the side which, when installed, is connected to the cover layer. To achieve special effects, however, it can also be expedient to provide cuts on both sides of the plates.
  • the incisions expediently run perpendicular to the plane of the plate, however oblique incisions, for example up to an angle of 75 ° to the plane of the plate, should not be excluded.
  • the distances between the individual incisions are 3 to 30 cm, preferably 5 to 20 cm, the depth of the incisions is greater than half the plate thickness.
  • the width of the cut slots is determined by the type of tool. It can be between 0 and 3 mm, preferably between 0 and 1 mm; If the slots are even wider, the insulating effect of the insulation board is
  • the two shares are preferably orthogonal; however, they can also run at an angle of 75 ° to one another.
  • the tools are e.g. Saws, cutting rings, rotating knives, glow wires or oscillating wires in question. It is also possible to make cut foam sheets directly by the molding process using molds with built-in thin-walled sheets.
  • the plate-shaped molded parts according to the invention can be laminated like 'conventional insulation materials on one or both surfaces parallel to the plate plane and folded at the edges.
  • Laminating materials include tensile, but slightly flexible materials, e.g. Nonwovens, fabrics made of textile or glass fibers, metal foils, plastic foils or bituminous waterproofing membranes as well as roofing felt are possible.
  • the molded parts With one-sided lamination and corresponding depth of cut, the molded parts can be rolled up as webs.
  • the lamination serves as tension reinforcement and / or as a vapor barrier and / or as a seal against drafts or water.
  • double-sided lamination double-sided reinforcement is obtained with the same additional functions as with single-sided lamination.
  • the molded parts according to the invention can be connected on one or both sides with rigid cover layers.
  • Gypsum plasterboards, asbestos cement, plastic or plywood panels and reinforced plaster are suitable as cover layers for such prefabricated composite elements.
  • the bending stiffness is determined exclusively by the cover layer.
  • the structure corresponds to the usual warm roof structure according to the guidelines of the German roofing trade.
  • a bituminized aluminum foil is first glued onto a load-bearing concrete ceiling, which is provided with a bitumen primer, as a vapor barrier. (The entire bonding and connections of the roof structure are carried out with hot bitumen.)
  • a perforated glass fleece bitumen roofing membrane is placed on the vapor barrier as a leveling layer.
  • the foam insulation layer according to the invention is then glued onto it. This consists of 12 cm thick, 1 m wide and 7.5 m long slabs of flame-retardant foam polystyrene with a density of 20 g / l laminated on the upper side with a carrier layer made of a glass fleece bitumen roofing membrane V 11 (according to DIN 52 143).
  • the panel tracks are.
  • the foam is provided with two orthogonal sheets of incisions that are 10 cm apart.
  • the incisions in the cutting coulter which is perpendicular to the longitudinal direction of the sheet, are 10.5 cm deep, those of the other cutting coulters are only 8 cm deep. Because of the relatively deep incisions perpendicular to the longitudinal direction, the panel track can be rolled and is therefore easy to handle during transport and laying.
  • a layer of a nonwoven bituminous roofing membrane V 13- (according to DIN 52 143) is glued to the insulation layer, and above it a bitumen roofing membrane with a glass grid insert (200 g / m 2 ), which is roughly sanded on the top.
  • a flat roof insulation is obtained which is practically free from stresses resulting from the foam and in which the cover sheets are subject to a considerably lower tensile and crack stress than conventional warm roof insulation.
  • the thermal insulation layer according to the invention is glued onto a 24 cm thick sand-lime brick masonry using a conventional construction adhesive made from a synthetic resin dispersion with cement additive.
  • the insulation layer consists of 8 cm thick, 50 cm wide and 100 cm long sheets of flame-retardant foam polystyrene with a density of 15 g / l.
  • the plates are provided with two orthogonal panels with 6 cm deep incisions that are 10 cm apart (see drawing).
  • a base plaster with a thickness of 5 mm is applied to the insulation layer, in the middle of which a glass fiber mesh fabric is embedded as reinforcement. After the base plaster has hardened, a synthetic resin-bonded rubbing plaster with a thickness of 3 mm is applied.
  • An outer facade insulation is obtained in which, in contrast to conventionally constructed insulation based on untreated foam panels, no stress peaks occur over the butt joints of the panels, so that the risk of cracks in the outer layers is largely eliminated.
