UNIT OF CONJUGATION OF CONCRETE PIPE COLUMN WITH OVERLAPPING IN BUILDING FRAME (VERSIONS) Russian patent published in 2025 - IPC E04B1/30 

FIELD: construction.

SUBSTANCE: group of inventions relates to construction, namely to joints of columns and floors of multi-storey buildings. Unit of coupling of concrete pipe column with floor covering in building frame contains support element, on top of which support cantilevers are installed, which are partially brought into column body through slots in column wall with fixation by welded seams. Support cantilevers are brought into the body of the column at a distance of at least 1/7 of the diameter of the column, and have a variable relief in the upper part of the inner-column section, an additional upper support element in the form of a flange is installed above the support cantilevers on the outer side of the column so that the lower and upper support elements together with the support cantilever form an H-beam in the section. In another version of the invention, one of the cantilevers has a length exceeding the diameter of the column and is brought into the column diametrically, and the rest of the support cantilevers are brought into the body of the column at a distance of at least 1/7 of the diameter of the column.

EFFECT: considerable increase in bearing capacity and reliability of the assembly.
