FIELD: road and bridge construction. SUBSTANCE: invention refers to functional joints of motor-road bridges. Deformation joints includes rubber slab that carries metal plates. Central plate is arranged horizontally in upper part of slab and two side plates are placed in parallel to upper one. Lower part of slab has longitudinal cut under central plate. Side metal plates are F-shaped in cross- section, each of then is developed vertically with flanges and faces corresponding span with plane of peripheral flange. Spaces with central passage where stud with nut is put are formed between two adjacent flanges of each side metal plate. EFFECT: increased functional reliability of joint independent of season and weather conditions. 1 dwg
