ABSTRACT:
A three-way clamp for the assembly of structural frameworks is disclosed. The clamp includes a block-like clamp body provided with a first bore extending through the block and second and third bores intersecting with the first at right angles and intersecting with each other at right angles. The clamp body is slotted in the plane of the axis of the second and third bores, to form cantilever extension portions of the block body capable of being squeezed together by a single compression bolt. Strut-like tubular structural elements are received in the several bores, one passing through the block, the other two being inserted endwise into the second and third bores. By tightening the single compression bolt, the clamp body is caused to be tightened down into secure gripping relation with structural elements in each of three right-angularly related, intersecting axes, significantly expediting assembly, disassembly and adjustment of frame structures.
