Abstract

PURPOSE:To make a homogeneous square tube with a high packing density, by forming a square-tubular molding space between inner and outer molds, supplying it with a mortar, then packing the flat of the molding space with the mortar and molding it centrifugally. CONSTITUTION:A square-tubular molding space 8 is formed with the outer shape of an end piece 4 and the outer face of an inner mold element 3 between an outer mold 2 and an inner mold 1, by combining another outer mold 2 with the former outer mold 2 to envelop the inner mold 1, and connecting the flange 11 of the fitted outer mold 2 with bolts to assembly the two outer molds 2 to be a tube. The mortar is put from a hole 14 into the inner mold 1, and a tire 12 is mounted on the rotating wheel of a centrifugal machine to rotate the mold. The molding space is filled with the mortar form the inner mold 1 through grooves 5; so that the molding is performed.
