发明名称 Methods and apparatus for forming and placing generally horizontal structures
摘要 One embodiment of the present invention provides for a method of placing a concrete structure in a generally horizontal position. The method includes building the concrete structure in an essentially vertical position, the concrete structure being defined by a first end. The concrete structure is pivotably supported at a support location proximate the first end while the concrete structure is in the essentially vertical position. The concrete structure is then pivoted about the support location to move the concrete structure from the essentially vertical position to the generally horizontal position.
