METHOD FOR CONNECTION OF ECCENTRICALLY LOADED COLUMN WITH STEPPED FOUNDATION Russian patent published in 2005 - IPC

FIELD: building, particularly frame structures for civil and industrial buildings to be erected mainly on sinking territories or territories to be developed.

SUBSTANCE: method for connecting eccentrically loaded column with foundation by fixing thereof in orifice formed in foundation involves forming composite multi-stepped foundation having central, medium and outer steps and through wedge-like orifices made in each step, wherein orifices taper downwards with cone angle of 1/10 to 1/5 (5.7 - 11.3^o) and each step and lower column end are also wedge-like and have cone angles of 1/12 - 1/6 (4.8 - 9.5^o), steps are inserted one into another and wedge-like column end extends into central orifice of central foundation step; tightly installing pair of force mounting wedges in gap between wedge-like column end and foundation, wherein each mounting wedge comprises two levers pivotally connected by the first ends to change cone angle of wedge and to regulate column verticality; securing jack communicating with hydraulic pulsing pumping plant to one lever; filling gap between foundation steps and gap between wedge-like column end and foundation with solid powder material, particularly with crushed granite with particle dimensions of 5 - 10 mm; covering upper part of central orifice of central step with concrete plug of 40 - 50 mm thickness along column perimeter; arranging centering pads on concrete plug symmetrically about eccentrically loaded column; installing pair of jacks on centering pads; securing mounting device formed as split terminal including L-shaper rests pressed to column and connected one to another by means of two bars and pins with stressing nuts, wherein jack pistons cooperate with L-shaped rests from below to maintain design position of eccentrically loaded column and to solidify powder material in gap between column tip and foundation orifice wall.

EFFECT: provision of straightening column position relative foundation without connection unit damage; increased reliability of anchoring eccentrically loaded column in foundation.
