METHOD FOR MANUFACTURING CONSTRUCTION ELEMENT WITH PERFORATED WALL Russian patent published in 2017 - IPC E04C3/294 E04B5/36 E04C3/07 

FIELD: construction.

SUBSTANCE: method for manufacturing a construction element includes: marking the initial profile (1) of a closed configuration along zigzagging broken lines (2) applied to its walls; cutting the original profile (1) along the zigzagging broken lines (2) to form the separate parts (3) and (4); arranging the parts (3) and (4) one above the other with the contact by the protruding edges of the corrugations (5); the interconnection, for example, by welding; installing the elastic chamber (7) inside the resulting profile (6) and installing the butt plugs (8) on the profile; on the lateral surfaces of the resulting profile (6), having the perforations (9), the temporary linings (10) fastened by the clamps (11) are mounted, after which a hardening material (12) is injected inside the elastic chamber (7), for example a concrete mixture, a cement-sand mortar, polystyrene foam, and the like.

EFFECT: due to the method of manufacturing a construction element with a perforated wall, the element shape stability increases during the manufacture and the operation.
