Abstract

1326505 Making expansion joints; spinning COMBUSTION ENG Inc 3 May 1971 [4 May 1970] 12703/71 Headings B3A and B3J [Also in Division F2] A method of making corner pieces 26 for an expansion joint 16 having a U-shaped crosssectional configuration from a flat sheet metal plate comprises providing a central opening in the plate, forming the plate about the opening into a surface of revolution g, welding together two formed plate means with their minor diameter ends in abutment and cutting the welded assembly a to form corner pieces which substantially subtend 90 degrees. The surface of revolution g is formed by mounting the plate in a chuck c of a spinning lathe and forming the surface by a spinning roll f. The formed plate may be cut diametrically into halves, the minor diameter ends of the halves welded together and the so-formed assembly severed in half to produce two corner pieces. The corner pieces 26 are welded to members 20, 22 to form a joint membrane and plates 38, 40 are welded to the top and bottom of the membrane, these plates preventing damage to the joint when it is welded to structural members 33 on site. The members 36 form part of conduit sections (12), (14), which are joined by the joint 16, Fig. 3 (not shown).
