Abstract

Improvements in the molds for precompressed concrete tubes, with a fitting and a male profiled end, characterized by the fact that they are arranged in combination, in the annular space left between a main hole of a stretchable external elastic sleeve and an outer shell coaxial with respect to said hole : a hole of circular lace that surrounds one of the ends of the main hole and is constituted by a certain number of rigid circular sectors, juxtaposed and surrounded by an elastic envelope; a stretchable outer sleeve that forms the external impression of concrete molding; and, finally, an elastic circular hole for forming the male end, which hole is surrounded by a portion of the dilatable sleeve that is applied to it.
