CONNECTION OF SANDWICH-TYPE BUILDING PANELS Russian patent published in 2020 - IPC E04D3/362 E04C2/26 

FIELD: construction.

SUBSTANCE: invention relates to sandwich type panel connection structures for making enclosing structures, heat-insulating and non-load-bearing structures of buildings and structures, and roofing. Connection of sandwich-type building panels, which contain outer and inner plies made of metal sheets with heat insulation layer arranged between them, fixed to each other by means of male and female elements made on edges of outer plies of one and the other adjacent panels. Covered element is formed from outer skin of one panel of two layers, in the form of letter "L" in cross section or in form of letter "L" turned in 180° in cross section, with cross bar, end of which is directed from panel end, wherein the second layer of the external lining of the male element is continued as a flange along the edge of one panel and is made deeper than the level of the surface of the outer lining in front of the male element, on the flange and inner lining of one panel there are holes, in which there are means for fixing panels to the building support, outer skin of the other panel is made with part protruding beyond the end of this panel, and on its edge female element "L" is formed in cross section or in form of letter "L" turned in 180° in cross section with end bent to outer skin, wherein above external coating plating of one panel with holes and means for attachment to construction support part is installed, which protrudes beyond the other panel end face. Said outer element covering element of the other panel is installed on double-layer male element of outer covering of the first panel, and they are fixed by folding.

EFFECT: technical result of proposed connection of sandwich-type building panels is increase of connection strength and its reliability at simple installation.
