STATIONARY SUPPORTING PART Russian patent published in 1997 - IPC

FIELD: construction, in particular, may be used for elongate constructions such as bridges, crane platforms, pipeline junctions, transportation galleries. SUBSTANCE: stationary supporting part has equalizers, which receive vertical supporting loading at free contact, pivot joint positioned between equalizers and provided with carrier cylindrical surface and devices for restricting vertical motion, which may occur under the action of horizontal loadings. Restricting devices are made in the form of eyelets removably mounted on equalizers and each provided with slot whose edges are extending in parallel with vertical supporting loading and joined with end portions of pivot joint so that they may slide along slot for value at least equal to value of approaching of equalizers to each other due to diametral compression of pivot joint by vertical supporting loading at free contact. At least one equalizer have eyelets with inserts received for sliding within slots. Inserts are provided with openings, which are joined with end portions of pivot joint concentrically relative to carrier cylindrical surface of pivot joint. Contact points of pivot joint end portions engageable with eyelets free of inserts may be made flat and are joined with eyelets for sliding within them. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 3 cl, 5 dwg
