Wall forming construction unit

Claim 1

For use with a generally planar wall form for use in a wall construction, a plurality of commonly aligned trusses, wherein each truss comprises: an elongate main support, a rigidifying member spaced from said support and parallel thereto, a plurality of struts each having a first end and a second end and said struts interconnecting said main support and member defining a framework, said struts including a strut perpendicular to the support and to the member, and means to connect the first end of said perpendicular strut to the support and the second end of said perpendicular strut to the member, and a first strut and a second strut, and means to connect the second ends of said first and second strut to the rigidifying member on opposite sides of said perpendicular strut at its connection to the rigidifying member, and means to connect the first ends of first and second struts to the main support in spaced relation and on opposite sides of the connection of said perpendicular strut to said main support, said first and second struts being in a common plane with said perpendicular strut and extending from said rigidifying member and diverging with respect to one another and to the perpendicular strut toward the main support, said main support having a support surface facing away from said rigidifying member and including holes through said support surface for connection to the generally planar wall form, whereby the wall form when spanning a plurality of the commonly aligned trusses, a wall construction unit is defined; said main support includes: a first and a second spaced parallel member of rigid material each having a support surface in a common first plane and a pair of parallel spaced clamp surfaces in generally right-angular relation to the first plane, and extending toward said rigidifying member; and the first ends of said struts at said main support being sized for snug receipt between said clamp surfaces and, said means to connect tightly clamping the first ends of said struts between said clamp surfaces; said means to connect the second ends of said struts to the rigidifying member comprises a pair of plates, one of the plates of the pair being on each side of said rigidifying member and defining a slot and one of the second ends of each of said struts being in said slot at said rigidifying member, and said means to connect clampingly engaging the ends of said struts between said plates and in said slot.
