ELEMENT SHAPED AS HALF-SHELL AND DESIGNED TO MAKE HOLLOW STRUCTURAL ELEMENT Russian patent published in 2015 - IPC E04B5/32 

FIELD: construction.

SUBSTANCE: group of inventions relates to the technical field of designing buildings, structures and construction equipment. An element (10, 10'), having a shape of a half shell, is designed to manufacture a hollow structural element (110) jointly with an identical additional element (10, 10'), having a shape of a half shell, is made with at least one guide (20…20'''). The guide (20…20''') is designed for an additional element (10, 10') and is formed in the zone of the first half (11) of the periphery of its covering edge (12), so that the additional element (10, 10') is put on the element (10, 10') from the second half (11') of the edge periphery (12), located opposite to this first half (11) of the periphery, with the possibility of direction at the edge (12) and retention in the end position. Besides, the element (10, 10') additionally comprises a fixing hooked element (30) and a fixing surface (31), designed for contact interaction with a complementary fixing surface (31) and a complementary fixing hooked element (30) of the additional element (10, 10'), which are located accordingly opposite to each other approximately in the middle of the first and second halves (11, 11') of the periphery of the covering edge (12). At the same time fixing grooves (40, 40'), designed to grip the edge zone of the additional element (10, 10'), having the shape of a half shell, are formed at both sides of the fixing surface (31) on the covering edge (12). Besides, an accessory is proposed to make the elements (10, 10'), as well as the method of manufacturing, the method of connection and application of the element (10, 10').

EFFECT: improved reliability and simplified manufacturing o an element (10, 10').
