Method and apparatus for precision slip-forming of complex precast shapes

Abstract

A system and method for the rapid precision forming of complex precast shapes using a slip form table comprising a slip form assembly and a lift master. The slip-form assembly has a replaceable forming face secured to a compressible backing material which is supported by a rigid slip-form. The lift master has a base master cast in the shape of the desired final cast block, with integral cast lift beams. A drive mechanism raises and lowers the base master relative to the slip-form assembly. The table has a leg and tie-down support. The slip form table may support a single block casting operation, or may support multi-stack casting. The lift master and slip-form may be precision concrete castings.
