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.
