Abstract A portable roof truss and floor joist fabricating apparatus which is a ''''jig-like'''' fabricating table on which is positioned a plurality of bracket plates for retaining the frame members in an assembled condition for fastening. The fabricating table comprises an elongated lower chord support beam as one side of the fabricating table and contains on one side thereof a plurality of mounting points to which are held a plurality of outwardly extending extension beams. On each extension beam and the lower chord support beam are mounted at least one detachable bracket plate with blocking brackets attached thereto for properly positioning each frame member. The members are fastened with toothed nailing plates or more preferably truss nails fastened through truss plates positioned on opposites sides of the frame members at the joint. In a preferred embodiment the frame members are secured by nails clinched with a ribbed clinching plate.
A portable apparatus for fabricating wooden roof trusses or floor joists comprising in combination, an elongated support beam having a plurality of mounting points on at least one side thereof for positioning a plurality of extension beams thereon, a plurality of extension beams mounted to said mounting points and extending outwardly from said support beam, means for rigidly securing and detaching said extension beams to said support beam to form a fabricating table, detachably mounted blocking means on the upper surface of said fabricating table for positioning frame members of a truss or joist in an assembled condition with joints for fastening, and wheel means for supporting said fabricating table and to pErmit movement of said fabricating table to a selected location.
