  • the layers are joined together in such a way that the webs 19, 20 come to lie on one another rotated by 90 °.
  • Fig. 15 shows; in its representation the arrangement of the webs 19, 20 in the layers 22, 22 '.
  • the half section shows that the lower layer 22 ', as seen in the plane of the table, has vertically oriented web groups 21 and the overlying plate has web groups 21 which are rotated by 90 ° thereto, so that here, as also shown in FIG.
  • insulation elements in accordance with 12 to 16 with insulation element designs acc. to combine the figures 3 to 11 and to make a meaningful use. It is according to the insulation elements.
  • Figures 1 to 16 peculiar that they can be used as independent wall elements in buildings without supporting aids such as girder scaffolding, retaining walls and the like.
  • the end and side surfaces can be provided with tongue or groove-like fixing elements which fix the elements independently in their position or also take mortar or adhesive to the elements in line with the walls on their end and side surfaces connect with each other.
  • the fixing elements are not shown separately in the drawing because they can be very diverse and are also known per se to those skilled in the art.

  • the 19 presents an insulating element 34 with a surface coating 35, the chamfers 36 on the edges assigned. As shown in more detail in FIG. 20, the coating 35 extends over chamfers 36 to to the edges of the side surfaces 38.
  • the element 34 can have a width of up to 2400 mm and is in it Length, due to the continuous formatting and coating on the production line, kept variable. It has a rectangular formatting here, but can correspond to the technological conditions of the building, take on any geometric, flat shape.
  • Fig. 20 shows that the fiber course 37 of the fibers of the laminated insulation element 34 perpendicular to the large ones Body axes 39; 39 'is directed.
  • the shape of the embracing of the fiber shafts 40 is shown in FIG. 21.
  • a very large enlargement of one Detail of the coated surface reveals that the fiber shafts 40 are encased with a small amount Penetration 41 of the coating medium goes hand in hand with the insulating element 35 and is nevertheless a homogeneous, gapless Surface coating 35 guaranteed.
  • the intimate connection of the coating material with the cross-sectional areas of the fibers and the properties of the coating material ensure a tear resistance that is comparable to that of the insulation material leaves and is pragmatically at 60 to 60 kPa.
