ABSTRACT:
Framing members of metal are produced from three tubular elements in parallel adjacent relationship held together by transverse fasteners. Sealing strips are located between the adjacent surfaces of the elements and subjected to pressure by the fasteners. In one form of the invention each of the fasteners comprises two pins, each of which passes through two elements so that the pin ends lie in opposed juxtaposition within a common element of the three and are secured together by collets. Alternatively, welded studs are employed. The members are joined together to form a frame by internal blocks shaped to suit the shape of the joint, e.g. angle or tee, and secured by clamping screws or riveting.
