FIELD: construction.SUBSTANCE: invention relates to an element in the rail-track top structure, in particular, to the element of intermediate rails connection attachment. Under-rail cushion comprises bent edge sections (1) with rounded bottom projections (2). Under-rail section (3) with corrugation (19) is limited by two transverse projections (4) with lateral cutouts that make shelves (5). Under-terminal sections (6) are located at opposite sides of the under-rail section. Under-terminal section comprises fastening hole (7), is limited at one side by a bent end section and is equipped with two longitudinal projections (8), as well as by limiting projections (9, 10). Limiting projection (9) is located opposite the cross projection and is connected to it. Limiting projection (10) is solid and is located opposite the bent end section, with which it is connected at an angle to form stiffness rib (11). At the connection point of limiting projections with crosswise projections (4) there is formed circular patch (16). Rear side is provided with stiffness ribs and recesses.EFFECT: there is achieved higher rigidity and strength of elements of under-rail cushion, as well as improvement of its adhesion to the rail.6 cl, 3 dwg |
