TRAVELLING FORMS FROM VOLUME BLOCKS ON BEARING METAL PIPES (VERSIONS) Russian patent published in 2013 - IPC E04G11/20 

FIELD: construction.

SUBSTANCE: travelling forms from volume blocks on bearing metal pipes comprises form blocks and bearing metal pipes, which are arranged between the inner (IPS) and outer (OPS) protective shells. The form on the inner surface of the IPS is a tight lining 3, made of sheet metal, which is substantially a non-removable form. On the outer surface of the OPS there might be any form used from the available ones, making it possible to concrete cylindrical structures. The form is equipped with a system of turn-buckles or hydraulic cylinders of double-sided action, hingedly connected with the beams of form shields of the outer and inner shells, and a system of sliding rolled metal pipes of square cross section, which are rigidly connected with beams of form shields and are welded to sections of rolled metal pipes, which are put onto bearing rolled metal pipes and are fixed on them in the design position with the help of bolts inserted into specially provided holes in the bearing pipes and pipe sections moving along bearing pipes.

EFFECT: simplification of design.
