Apparatus for positioning and holding truss members

摘要

Apparatus for positioning and holding on an elongate bed pieces of a floor truss of the type comprising a pair of generally parallel spaced-apart wood chord members and a series of relatively flat metal web members having connector portions with teeth struck therefrom to be pressed into the wood chord members for rigidly interconnecting them. The apparatus comprises an abutment having a first vertical clamping surface extending longitudinally with respect to the bed for engagement by one chord member, and a clamping mechanism for moving the web and chord members relative to one another from an initial unassembled position in which the web members are generally horizontal with the teeth facing upwardly and in which the wood chord members overlie the web members, to a final position in which the one chord member abuts the aforesaid clamping surface of the abutment and the connector portions of the web members are substantially centered on the lower faces of the chord members transversely with respect to the faces. The clamping mechanism also clamps the web and chord members in their final position.
