Apparatus for manufacturing prestressed concrete members

摘要: A system for casting prestressed concrete members on a highly automated, mass production basis. The employs plurality of portable molds, each which defines hollow mold cavity. molds are preferably substantially identical in construction, include open top portions through charges mixture can be directed into the cavities, and further means releasably securing lengths reinforcing strand selected arrangement within Conveying carry simultaneously along predetermined path travel operating stations adapted to subject series successive operations. cleaning oiling station cleans interior surfaces cavity coats with releasing agent. An placement inserts hardware cast members. emplaces mode tensioning applies pretensioning force strand. Filling compacting successively feed measured charge compact molds. Means provided cure after filling operations completed. Conveyor receive convey curing operation is tension operates release load emplaced downstream from preparing removal demolding remove member mold. also finish demolded prepare empty recirculation manufacturing system. In preferred embodiment mold, perform their respective simultaneously, time interval.
