  • Cross joint anchoring is particularly suitable for connecting sandwich panels as described for the embodiment of Figure 1 are because due to the waterproofing membrane a Cross-bridging plastic strips can be applied. Nevertheless, transverse impacts can also occur in the manner described connected by conventional sandwich panels or roof construction elements , so that a cross joint anchoring as in the Embodiments of Figures 5, 6 and 7 are not necessarily shown a use of the sandwich panels described above is.
  • FIG. 8 shows two to be engaged with one another on the longitudinal butt side Sandwich panels 54, 54 '.
  • the embodiment with the sandwich panels 1, 1 ' is the upper one Sheet metal cover layer 55 or 55 'and the lower sheet metal cover layer 56, 56' their anchoring in the hard foam core 57 or 57 'and anchored in it.
  • the edge formation of the sheet metal cover layers 55, 55 ', 56, 56 ' is designed in the manner of an expanded metal.
  • the trained as expanded metal Sections are shown in FIG. 8 with respect to the sheet metal cover layers 55, 55 ', 56, 56 'shown in dashed lines.
  • the expanded metal or expanded metal sections the sheet metal cover layers 55, 55 ', 56, 56' serve for better clamping with the respective hard foam.
  • FIG. 8 The exemplary embodiment described for FIG. 8 is particularly suitable for anchoring the sheet metal cover layers of the sandwich panels 54, 54 ' are basically constructed like the sandwich panels 1, 1 'of FIG. 1. Nevertheless, in the manner described for FIG Sheet metal cover layers of conventional sandwich panels or roof construction elements be connected so that the description of this embodiment not necessarily to use the sandwich panels 54, 54 'is limited.
  • the sandwich panel described is not only suitable for training a roof and thus for training as a roof component, but ultimately the sandwich panel can be used in all applications, where an outside and / or inside plastic coating is desired and in particular an effective moisture and Vapor barrier is to be formed through this plastic layer. Therefore this sandwich panel is also suitable for the formation of walls or similar.
