Definitions

  • the invention relates to an insulation board made of rigid foam plastic, the width of which is adapted to the width of a corrugated asbestos cement board and has a corresponding undulating surface on one side, in which the crests and troughs are perpendicular to the width, in which the edge regions parallel to the crests and troughs run out in an edge wave crest and in an edge wave trough, in which these edge regions are formed fold-like on their end faces and in which the edge wave crest of one edge region is reduced in width along its outer flank.
  • Such an insulation board made of hard foam plastic is known from DE-U-81 12 036 and is used for thermal insulation of a roof covered with corrugated asbestos cement boards.
  • This roof which is insulated in this way, is accessible because the insulation board with its wave crests and wave troughs is supported on the corrugated asbestos cement boards over a large area.
  • the edge areas parallel to the wave crests and wave troughs are provided with a fold on their end faces, since in the overlap areas between two adjacent corrugated asbestos cement plates, the division predetermined by the corrugation thereof deviates more or less. This depends on the laying of the corrugated asbestos cement boards. If you then do not want to worsen the support of the insulation boards, there is always a more or less wide parting line on the end faces of adjacent insulation boards in the overlapping fold area, which considerably deteriorates the thermal insulation, especially in the overlap areas.
  • the edge wave crest on its outer flank must be shortened in width so that the overlapping end of the following corrugated cement board of a roof can be accommodated. There is therefore a further deterioration in the thermal insulation in the overlap area with the reduced edge wave crest.
  • the fold on the end faces of the edge areas is also only one step, the fold of the subsequent insulation board engaging over the fold of the insulation board that has already been laid. Therefore, when the insulation boards are installed at the joints of the insulation boards, the last insulation board installed is not automatically held. This makes it difficult to lay the insulation panels on a roof covered with corrugated asbestos cement panels.
  • the end face of the one edge region is provided with a connecting groove and the end face of the other edge region is provided with a connecting web aligned and coordinated therewith in that the connection depth between the connecting groove and the connecting web is greater than the difference between the two maximum and minimum distance between the adjacent wave crests or adjacent wave troughs of the corrugated asbestos cement plates abutting in the overlap area and that at least the part of the end face of one or the other edge area lying outside the connecting groove or the connecting web is connected with a strip of soft foam plastic, the width of which is greater than the connection depth between the connection groove and the connection web.
  • the surface opposite the undulating surface is flat and provided with a final roof skin.
  • the final roof skin increases the rigidity and thereby improves the walkability.
  • the surface opposite the wave-shaped surface is also wave-shaped, the wave crests of which coincide with the wave troughs and the wave troughs of which coincide with the wave crests of the wave-shaped surface and that the wave-shaped, opposite surface is also provided with a final roof skin. then the same thermal insulation can be achieved with a smaller volume of the insulation panel, since the insulation panel has a uniform thickness over the entire width.
  • the plugging together of adjacent insulation boards is facilitated in one embodiment in that the side walls of the connecting groove and the connecting web are inclined at the same acute angle to the level of the insulating board, the distance between the connecting groove of the flat outside increasing with increasing groove depth.
  • the insulation board to be lined up with a laid insulation board can then be held at an angle in order to insert the connecting web into the connecting groove. It is advantageous if the design is carried out so that the connecting groove in the edge Area is introduced, which runs into the edge wave crest and that the connecting web is formed on the edge area, which ends in the edge wave trough.
  • the part of the end face lying outside the connecting web is connected to the strip made of soft foam plastic and that the groove base of the connecting groove is also connected with a strip made of soft foam plastic, whose width is greater than the connection depth between the connecting web and the connecting groove and whose height is equal to the groove width, so that the connecting web covers and protects the strip.
  • the production of the overlapping connection of adjacent insulation boards is made even easier by the fact that the end face of the edge area running out into the edge wave crest is set back relative to the edge wave crest and that the edge wave trough of the opposite edge area merges directly into the connecting web, which on the correspondingly preferred one End face is formed.
  • the end face at the edge area with the edge wave crest is set back to approximately the dividing line in the area of the edge wave crest.
  • the insulation board can advantageously be covered in such a way that the approximately parallel longitudinal and outer edges of each two insulation boards with a common joint are provided with an outer skin with a sealing body that connects them in an impermeable manner.
  • the sealing body consists of an elastically deformable plastic. If the outer and longitudinal edges of the interconnected insulation boards overlap, then it is expedient if the sealing body is band-shaped and has a thickness which is greater than the distance between the overlapping parts of the longitudinal and outer edges.
  • the sealing body has an essentially U-shaped cross section, the distance between the leg edges from one another being at least half and at most two wavelengths of the corrugated asbestos cement plate.
  • a good medium-impermeable connection between the outer skin and the sealing body can be achieved in that the side of the sealing body facing the insulation board is provided with a soft plastic, preferably foam.
  • the width of the corrugated asbestos cement panels 30 and 30 'and the insulating panels 10 and 10' are matched to one another so that the joint between the two colliding insulating panels 10 and 10 'coincides with the overlap area of the adjacent corrugated asbestos cement panels 30 and 30' .
  • the surface of the insulation board 10 or 10 'facing the corrugated asbestos cement board 30 or 30' is wave-shaped, so that a full contact is achieved. So that a simple stringing together of the corrugated asbestos cement panels 30 and 30 'can be achieved, one edge region ends in a wave crest and the other edge region in a wave trough.
  • the one edge region of the insulation board 10 also runs into the edge wave crest 13 and the other edge region of the insulation board 10 'into the edge wave trough 15'.
  • the insulation panels 10 and 10 ' have between their wave crests 11 and 11' and their wave troughs 12 and 12 'a uniform division, which is given by the corrugation of the corrugated asbestos cement panels 30 and 30'.
  • the connecting web 18 'formed on the end face 20' of the insulating plate 10 ' only projects a part into the connecting groove 17 which is made in the end face of the insulating plate 10.
  • the strip 21 is attached, which consists of soft foam plastic and is already compressed in this position, since it has a width which is greater than the connecting depth between the connecting web 18' and the connecting groove 17.
  • This connecting depth is maximum if the edge area 28 ′ covers the edge area 29 as much as possible, as shown in FIG. 2.
  • the division takes the smallest value in the overlap area in this position. The differences resulting from the positions of FIGS.
  • 1 and 2 limit of the distance between the end faces 19 and 20 ' is compensated for by the strip 21.
  • a strip 22 made of soft foam plastic is also introduced into the connecting groove 17 and connected to the bottom of the groove, then the parting line between the bottom of the connecting groove 17 and the end face of the connecting web 18 'is also filled and depending on the position of the insulation boards 10 and 10' in Area of the joint balanced and clear thermal insulation ensured.
  • the width of the strip 22 is chosen like the width of the strip 21, and the strips 21 and 22 can be compressed to the sizes denoted by 21 'and 22'.
  • the outer surface of the insulation panels 10 and 10 ' is flat and can be provided with a roof skin 23 and 23' to increase the strength.
  • the outer surface of the insulation panels 10 and 10 ' can also be designed in a wave shape, the wave crests of the outer surface with the troughs 12 and 12' of the wave-shaped inner surface and the troughs of the outer surface with the wave crests 11 and 11 'of the undulating inner surface coincide, so that there are insulation panels 10 and 10 'of uniform thickness. If a given thermal insulation is to be maintained, this can be achieved with insulation panels 10 and 10 'according to FIG. 3 with a smaller volume, as with insulation panels 10 and 10' according to FIG. 1 or FIG. 2.
  • the undulating outer surface can also be used a roof skin 23 or 23 '.
  • the end face 19 of the insulation board 10 is set back as far as the dividing line of the edge wave crests 13 and the end face 20 'of the insulation board 10' is accordingly advanced, the edge wave trough 15 'passing directly into the connecting web 18'.
  • the connecting web 18 'and the connecting groove 17 with their side walls are inclined at an acute angle to the flat outer surface, the insulating plate 10' can be inclinedly inserted into the insulating plate 10 already connected to the corrugated asbestos cement plate 30, immediately stopping in the area of the joint is achieved.
  • the crests 11 ' automatically bring the alignment and adjustment to the changed pitch given in the overlap area of the corrugated asbestos cement boards 30 and 30'.
  • the strips 21 and 22 achieve unambiguous thermal insulation also in the area of the joint of the two adjacent insulation boards 10 and 10 '.
  • the formation of the end faces with the connecting grooves 17 and the connecting webs 18 ' also facilitates assembly, i.e. the laying of the insulation boards 10 and 10 '.
  • the left edge of the insulation board 10 is correspondingly provided with the edge trough and the connecting web.
  • the right edge of the insulation board 10 ' has the edge wave crest and the connecting groove.
  • the joint between adjacent insulation boards 10 and 10 ' is additionally covered, specifically over one edge area of the roof skin 23' of the insulation board 10 '.
  • This edge area is designed as a wave-shaped extension 33, which projects at the assigned edge area of the insulation board 10 'and covers the roof skin 23 of the adjacent insulation board 10 in the assigned edge area 34. So that the joint between adjacent insulation panels 10 and 10 'is completely covered by the roof skin.
  • FIG. 5 shows, it is also possible to let the roof skins 23 and 23 'end at the edge regions with the insulation panels 10 and 10'.
  • the joint between the roof skins 23 and 23 ' can be covered with a cover strip 30 which extends over the adjacent edge wave crests of the abutting insulation boards 10 and 10'.
  • the underside of the cover strip 30 is provided with a soft insulating layer 31, which deforms accordingly and fills the space between the insulation boards 10 and 10 'in the area of the joint.
  • the connecting line 32 shows, the cover strip 30 is connected to the roof substructure through the insulation panels 10 and 10 '.
  • connection in the area of the joint between adjacent insulation boards 10 and 10 ' can be improved in that double folds are provided in the area of the end faces instead of a simple connecting groove and a matching connecting web.
  • the connecting grooves on one end face and the connecting webs on the other end face are inclined at a small angle in the opposite direction to the level of the insulating board, the connecting grooves with their insertion openings being offset toward the outside of the insulating board, then the nested insulating boards are inserted into Pulled towards the covered corrugated asbestos cement boards, which makes laying the insulation boards much easier.
  • the screw heads of the fastening screws projecting above the corrugated asbestos cement plates do not impair the laying of the insulation boards if it is provided that the troughs on the inside are provided with grooves running in the trough for receiving the screw heads from the fastening screws holding the corrugated asbestos cement plates.
