发明名称 Extruded plastic bulkhead device for forming concrete panels
摘要 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.
