FIELD: construction.
SUBSTANCE: inventions relate to construction, in particular to bridge construction and the construction of buildings and structures. Supporting part of the building structure contains an anchor plate, a lower and upper balance bars, an upper support plate with a horizontal bottom surface, covered with a corrosion resistant surface, upper surface of the upper balance bar is made horizontal with an antifriction coating, and the upper surface of the lower balancer is curvilinear, the lower balance bar is provided with lateral projections having cylindrical side bottom surfaces, and the upper support plate is made with side thrust beams with shoulder strikes that come with a clearance for the lateral protrusions of the lower balance bar. In the second variant of the supporting part of the building structure, the upper support plate is provided with thrust beams with shoulder strips directed in opposite directions, and the anchor plate on both sides is provided with L-shaped projections having cylindrical side lower surfaces, for which the shoulders of the abutment beams of the upper support plate pass with a clearance. In the third variant of the supporting part of the building structure, the upper support plate is provided with thrust beams with shoulder strips directed in opposite directions, and the anchor plate is provided on both sides with projections having slots with cylindrical bottom surfaces into which the shoulder struts of the abutment beams of the upper support plate come into play. In the fourth variant of the supporting part of the building structure, the upper support plate is provided with thrust beams which have slots, and the lower balance bar is provided with lateral protrusions having cylindrical lateral bottom surfaces that enter with a clearance in the slots of the abutment beams of the upper base plate. In the fifth variant of the supporting part of the building structure, the upper support plate is made with abutment beams, which have slots, and the anchor plate on both sides is provided with L-shaped projections having cylindrical side bottom surfaces, coming with a gap in the slots of the stop beams of the upper base plate.
EFFECT: increasing the reliability of the supporting part of the construction structure by creating the freedom of mutual displacements of the balancers.
