发明名称 APPARATUS FOR SHUTTERING POURED CONCRETE STRUCTURES
摘要 Apparatus for forming a poured concrete structure includes an inverted U-shaped shuttering member movably supported on a carriage. While supporting the shuttering member, the carriage can be moved over rails for placing the shuttering member in the location where it is to form the structure. When it is properly located, the carriage can displace the shuttering member laterally and vertically into the exact position for forming the poured concrete structure. Means are incorporated into the shuttering member for holding it in position to pour the structure so that the carriage can be removed from its position supporting the shuttering member.
