PIPE STRUCTURE Russian patent published in 2012 - IPC E04H15/60 

Abstract RU 2452837 C2

FIELD: construction.

SUBSTANCE: pipe structure comprises at least two pipes and a detachable pipe joint, which contains a flange serving as an axial support surface for tips of two pipes. At each side of the flange there is at least one ledge designed for entry into the appropriate cut in the tip of the appropriate pipe. Due to entry of ledges into cuts, pipes twisting relative to each other is prevented. At each side of the flange there is also a cylindrical section, which may be inserted inside the appropriate pipe. Besides, each cylindrical section has an axial gap, as a result of which flexible end parts are produced above and below the gap. The first flexible end part has a radial opening, where a screw is inserted for tight clamping of the pipe joint in the pipe.

EFFECT: higher strength of a pipe structure.
