FIELD: construction.
SUBSTANCE: invention relates to design of expansion joints (EJ) of comb and modular comb types used in bridge engineering. An EJ covered with combed fingers 1, between which there are elastic comb plates 3, having a stepped shape. Lower parts 4 of elastic comb plates 3 are rigidly fixed between a bearing beam 5 and comb fingers 1, with the help of the already installed bolt connection 7. Elastic comb plates 3 are formed into sections, with the help of a flat plate 8, comprising lower parts 4 of elastic comb plates 3.
EFFECT: safe passage of bicycle transport along an expansion joint and protection against penetration of snow, ice, garbage, gravel and crushed stone under an expansion joint, considerable increase of functionality of expansion joints by perception of transverse displacements and turns in plan of spans, and prevention of freezing and damage of comb fingers.
