Specific embodiment
Referring to the drawings, a kind of bridge type steel expansion joint serves as a contrast bar with filleting, and a pair of shaped steel 4 are arranged on expansion joint mirror image each other
Both sides, to constitute type steel expansion joint, the inner side of shaped steel 4 is equipped with opening towards the groove at expansion joint；The two ends difference of sealing strip 5 is embedding
It is located in the groove, and the centre of sealing strip 5 is less than two ends, and the slot of 4 synthesis opening upwards is enclosed with the shaped steel with both sides；
Filleting lining bar is used to be arranged in the slot, and filleting lining bar has elasticity；The filleting lining bar includes body
