摘要
Prefabricated prestressed concrete members are formed on a stressing bed with a number of working stations arranged next to one another along the length of the bed. A frame forms the working stations and the frame is immovable over the stressing bed. With a previously poured concrete member in one of the working stations, part of a form is placed in another working station and is filled with concrete. After the form part is completely filled and consolidated, a second form part is placed downwardly on the filled part, completing the form. A lifting member on the frame which placed the second form part on the filled part is then moved to the station containing the previously poured member which is still within the form. The form is stripped from the concrete member and the frame is then moved along with the lifting member, returning the stripped form to the working station where it is to be filled with concrete. After the stripped form is moved the second form part is separated from the part to be filled with concrete and is moved into another working station where it is cleaned and readied for the next working cycle.
