MULTIPLE JOINT OF CELLULAR STRUCTURE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: multiple joint includes casings and corrugated strips arranged between casings. Corrugated strips are rigidly connected to one another and to casings and forming cells. Casings are corrugated and oriented with corrugation axes as strips are, and connected with them to form cells. Corrugated strips on sections of mutual joining are profiled over their width to form open hollows coming out on longitudinal edges. Tubular hollows have covers on their ends and having coaxial holes in bottoms, and diametrically arranged longitudinal slots in walls installed so that paired in thickness strips are engaged in cover slots and clamped by means of coupling bolts passed through tubular hollows and cover holes. Provision is made of version of making of inner diameter of tubular hollows equalling the diameter of coupling bolt. EFFECT: higher efficiency. 2 cl, 1 dwg
