Adjacent tilt-up concrete wall panels are poured on a horizontal concrete floor or forming surface and are separated by a bulkhead device including a base member or channel of extruded semi-rigid plastics material and secured by screws to the forming surface. The base channel has upwardly projecting walls with inwardly projecting opposing teeth which releasably engage outwardly projecting teeth on spaced side walls of a generally U-shaped bulkhead member of extruded semi-rigid plastics material. The spaced side walls also have opposing ribs for gripping a bulkhead extension member, and the bulkhead member is also extruded with outwardly and downwardly projecting walls which have tapered lower edge portions engaging the forming surface to form chamfer corners on the concrete panels.
A device for separating adjacent concrete panels poured onto a forming surface, comprising an elongated base member adapted to be secured to the forming surface, an elongated generally U-shaped bulkhead member including a lower longitudinally extending portion releasably connected to said base member, said bulkhead member having generally parallel spaced longitudinally extending side walls defining a cavity adapted to receive a longitudinally extending bulkhead extension member projecting above said bulkhead member, and said base member and said bulkhead member comprising extrusions of substantially rigid plastics material.
A device for separating adjacent concrete panels poured onto a forming surface, comprising an elongated generally U-shaped bulkhead member including a lower longitudinally extending portion adapted to be releasably connected to the forming surface, said bulkhead member having generally parallel spaced longitudinally extending side walls defining a cavity adapted to receive a longitudinally extending bulkhead extension member projecting above said bulkhead member, said bulkhead member including chamfer forming walls projecting downwardly and outwardly from said side walls and having lower edge portions disposed for engaging the forming surface, and said bulkhead member comprising an extrusion of substantially rigid plastics material.
A device for separating adjacent concrete panels poured onto a forming surface, comprising an elongated U-shaped base channel having generally vertical side walls with inwardly projecting and longitudinally extending opposing teeth and adapted to be secured to the forming surface, an elongated generally U-shaped bulkhead member including a lower longitudinally extending portion releasably connected to said base channel, said base channel and said bulkhead member comprising extrusions of substantially rigid plastics material, said bulkhead member having generally parallel spaced longitudinally extending side walls defining a cavity adapted to receive a longitudinally extending bulkhead extension member projecting above said bulkhead member, and said bulkhead member including chamfer forming walls projecting downwardly and outwardly from said side walls and having lower edge portions disposed for engaging the forming surface.
