Precast reinforced concrete form

A form for forming poured-in-situ vertical concrete walls of residential or commercial buildings the form comprising a pair of precast reinforced concrete panels, each of the precast reinforced concrete panels having an inside surface facing the space in which the poured-in-situ concrete is to be placed and an outside surface, first and second vertical sides and a top end and a bottom end, the form further having a plurality of horizontal reinforcing trusses, each of said trusses having a first pair of longitudinal headers, said headers cast into one of said panels, and each of said trusses having horizontal reinforcing members extending from said one of the pair of headers and horizontal reinforcing members extending from the other of said pair of headers outwardly through the inside surface of said one panel to a second horizontal header cast into the other panel wherein each of the longitudinal headers is further reinforced by vertical longitudinal reinforcement rods linking each of said trusses.

A precast reinforced concrete form for forming poured-in-situ vertical rectangular columns of residential or commercial buildings, comprising a pair of precast reinforced concrete panels, each of the precast reinforced concrete panels has an inside surface facing the space in which the poured-in-situ concrete is to be placed and an outside surface, first and second vertical sides and a top end and a bottom end, wherein the precast form further comprises a plurality of horizontal and vertical reinforcing members cast into the panels.

A precast reinforced concrete form for forming poured-in-situ vertical square columns of residential or commercial buildings, comprising a square precast reinforced concrete panel with a hollow center, an inside surface facing the space in which the poured-in-situ concrete is to be placed, an outside surface and a top end and a bottom end, wherein the form further comprises a plurality of horizontal and vertical reinforcing members cast into the panel following the shape of the panel.

A precast reinforced concrete form for forming poured-in-situ vertical parapets of residential or commercial buildings, comprising a pair of precast reinforced concrete panels, each of the precast reinforced concrete panels having an inside surface facing the space in which the poured-in-situ concrete is to be placed and an outside surface, first and second vertical sides and a top end and a bottom end, wherein the form further comprises a plurality of horizontal reinforcing trusses, each of said trusses having a first longitudinal header, said header cast into one of the panels and horizontal reinforcing members extending from said header cast into the other panel and wherein each of the longitudinal headers may be further reinforced by vertical longitudinal reinforcement rods linking each of said trusses.

A precast reinforced concrete form for forming poured-in-situ vertical circular columns of residential or commercial buildings, comprising a circular precast reinforced concrete panel with a hollow center, an inside surface facing the space in which the poured-in-situ concrete is to be placed, an outside surface and a top end and a bottom end wherein the form further comprises a plurality of horizontal and vertical reinforcing members cast into the panel following the shape of the panel.

A method of making a form for forming poured-in-situ vertical concrete walls of residential or commercial buildings the form comprising at least one precast reinforced concrete panel, the method comprising:

• a. forming a mould for one of the precast panels,
• b. positioning a plurality of vertical reinforcing trusses off the base of the form for the first precast panel, each of said trusses having a pair of longitudinal headers, said headers to be cast into the panel, and each of said trusses having horizontal reinforcing members extending from said headers outwardly through the inside surface of said panel,
• c. pouring concrete into the mold with a sufficient cover to retain the pair of longitudinal headers, curing it, rotating it after reaching the required strength.
