METHOD OF STIFF CONNECTION OF TUBULAR CROSSBAR OVAL IN SECTION WITH GUNCRETE CARCASS PILLAR OVAL IN SECTION Russian patent published in 2013 - IPC E04B1/58 

FIELD: construction.

SUBSTANCE: bent crossbar is stretched via a unit as indivisible, solid. The lower pillar cap is arranged as trough-shaped with longitudinal bent ribs. The cap follows and covers the oval surface at the bottom. The crossbar is tightly inserted into the pillar cap, matching fixing pins with responsive holes in the cap trough. The base of the upper pillar is arranged same as the cap - trough-shaped, and is equipped with fixing pins with response holes in the cap bends. The upper pillar is mounted in a non-adjusting manner, matching fixators with responsive holes, and an oval tubular cavity is formed with the cap trough. The crossbar inserted into the cavity is tightly covered. Longitudinal ribs of the upper pillar base and lower pillar cap are connected to each other, for instance, by high-strength alloyed pins. They are securely tightened with a nut setter, and a single monolithic unit of pillars and the crossbar is created.

EFFECT: automation of a process of structure carcass erection, increased manufacturability of a process, reduced labour intensiveness and higher reliability of connection.
