UNIT OF METAL FRAME CARCASS OF BUILDING Russian patent published in 2013 - IPC E04B1/58 

FIELD: construction.

SUBSTANCE: unit of a metal frame carcass of a building includes a double-tee column, combined with a double-tee beam, which creates a column cantilever, which is rigidly connected in the zone of least bending torques by means of flanges on high-strength bolts with a crossbar, having the cross section corresponding to the section of the column cantilever. The column is equipped with an upper stiffening rib and paired lower stiffening ribs, symmetrically arranged at both sides of the column wall in the level of the lower shelf of its cantilever. Between the upper and lower stiffening ribs of the column in parallel to its shelves there is a vertical rib for connection of the spacer and the vertical link to it, and to the column wall above the neutral axis of its cantilever and in parallel to its shelf there is a polygonal plate attached to the shelf, and this plate protrudes beyond the edge of the upper stiffening rib, for fixation of the horizontal link. Central longitudinal axes of the spacer, horizontal and vertical links are connected in one point arranged in the frame plane.

EFFECT: unit strength improvement.
