Body assembled from at least two component bodies

Claim 1

In a body assembled from at least two component profiled-section metal bodies, having connecting heat-insulating profiled rails arranged between the component bodies each of which in cross section has a stem part and two end thickenings, the latter when pushed with play into undercut grooves of the component bodies form a cavity enclosed between the component bodies and the rails filled with a filling composition exerting an expansion pressure whereby the connecting rails are subjected to tension stress lengthwise of the stems thereof, said rails having stop faces on the end thickenings extending substantially perpendicularly of the tension direction and intended to abut on complementary groove undercuttings, the improvement comprising a stop face formed in the metal section groove opposite said stop face on the end thickenings and oriented at an oblique angle to such tension direction, said end thickening on the said connecting rail having a surface laying at substantially the same oblique angle to such tension direction as said obliquely arranged metal section stop face for engaging same when the perpendicularly arranged stop face and complementary groove undercutting engage, said perpendicularly arranged stop faces and obliquely arranged stop faces being on opposite sides of said connecting rail end thickening to wedge said connecting rail and metal sections together against lateral bending of the rails out of interlocked position with said sections, said end thickenings only partially filling said undercut grooves in the component bodies to provide small recesses between said end thickenings and the groove wall of the component bodies, the connecting profiled rails are provided in the region of the end thickenings with recesses and projections permitting the entry of filling composition from the cavity into the small recesses between the groove wall and the end thickenings for further retaining said stop faces and oblique surfaces of the end thickenings abutting on the complementary groove undercutting and oblique stop face of the metal bodies.
