CONNECTOR FOR PROFILE PIPES (OPTIONS) Russian patent published in 2021 - IPC E04B1/24 E04B1/38 E04B1/58 

FIELD: construction; furniture manufacturing; mechanical engineering; electrical engineering.

SUBSTANCE: connector for profile pipes is used to fasten rectangular profile pipes in the manufacture of bulk modular and frame structures in construction, furniture manufacturing, mechanical engineering, electrical engineering, etc. The connector of profile pipes located at an angle to each other contains two plates, one of which is made rectangular, and the other is L-shaped. Both plates contain threaded bushings placed in holes coaxially made in the profile pipes and designed to fix the profile pipes by screwing fasteners into them. The plates also contain transverse grooves for the mutual connection of both plates at an angle by engaging them one after the other. In addition, the L-shaped plate has a hole designed to fix it to the profile pipe by means of a fastener attached to the expander nut placed in the profile pipe. Options for connecting profile pipes are also described.

EFFECT: increased strength and reliability of the assembled unit, obtaining a collapsible connection, as well as reduced labor costs when assembling bulk modular structures.
