ABSTRACT:
There are disclosed a method and an apparatus for producing an elongated concrete member of a trapezoid cross section for use as a cross tie, i.e., a prestressed concrete member for fixing rails of railroads. Those methods and apparatus include in sequence, the steps of attaching end plates to a mold having an open top surface and end plates removed beforehand, said attaching operation being carried out in the condition of said mold having an open top surface and end plates removed beforehand, said attaching operation being carried out in the condition of said mold being transported in the longitudinal direction of said apparatus but lengthwise of said mold to complete the assembly of said mold, said mold being of such a construction that an elongated concrete member of a trapezoid cross section may be molded upside down; stocking said mold thus assembled in the transversely transportable condition; placing concrete into said mold, stamping and vibrating same; curing said concrete thus placed in said mold, transporting in the longitudinal direction of said apparatus said mold containing said elongated concrete member which has completed curing; removing said elongated concrete member from said mold; finishing said elongated concrete member thus removed; and returning said empty mold to an assembly.
