ABSTRACT:
A simplified, low-cost forming system (46) and method for the rapid construction of integrated, monolithic cast structures such as storm shelters (20). The preferred forming system (46) includes an inner core form member (48) presenting a base (54) and upstanding sidewall structure (56), together with an open-top outer form member (50) having a circumscribing sidewall assembly (118) and a superstructure (120) releasably secured thereto. In use, the outer form member (50) is telescoped over the inner core form member (48), with the distance between the form walls defining the thickness of the resulting shelter (20); preferably, a reinforcing grid (52) and door frame (32) are located between the form members (48, 50). After form assembly, concrete (178) is poured through the open top of the outer form member (50) to fill the complete form. Upon setting of the concrete (178), upper jacks (182) are positioned between the superstructure (120) and the shelter (20), and are used to separate and allow complete removal of the outer form member (50). The shelter (20) is then separated from the inner core form member (48) through use of lower jacks (82) which elevate the shelter (20) relative to the inner core form member (48). In a second embodiment of the invention, a second outer form member (200) includes corner jacking assemblies (202, 204, 206, and 208) for expediting separation of the shelter (20) and the second outer form (200).
