SUPPORT PART AND METHOD OF ITS ASSEMBLY Russian patent published in 2011 - IPC E01D19/04 

FIELD: construction.

SUBSTANCE: support part comprises an upper board with side longitudinal stops, attached to a support assembly of a span, a lower support board fixed on a support head, upper and lower beams with response convex and concave spheres, equipped with antifriction layers, and side planks with fixing accessories. The novelty is the fact that there are holes in planks, and in longitudinal stops there are threaded holes coaxial to them with a pitch, which corresponds to length of span support assembly movement at the specified ranges of support part assembly temperature, besides, fixing accessories are installed in holes of planks and threaded holes of longitudinal supports. The method of support part assembly consists in delivery of pre-assembled support part to the area of assembly, fixation of the lower board of the support part to the support head and attachment of the upper board to the support assembly of span at the specified range of ambient temperatures. The novelty is the fact that previously average rated ambient temperature is identified at the moment of the support part assembly, then, in factory conditions, the support part is adjusted for this temperature by displacement of the upper board by value of temperature deformation of span at this temperature, position of the upper part is fixed in this position, and the support part is transported from the factory to the area of assembly, besides, the upper board in this displaced position is attached to the span coaxially to the support assembly.

EFFECT: increased operational reliability.
