Segmented fingerboards are not integrated even after construction, so if the construction is poor or if an irregular vehicle load is applied to the fingerboard, the fingerboard may fall off and lead to a secondary accident. may decrease.
Finger type expansion joint device for bridges using eyebolts
By attaching eyebolts to the lower steel plate and passing reinforcing steel bars through them, it is possible to firmly fix the reinforcing steel bars and prevent the reinforcing bars from flowing and separating when non-shrinkage concrete is poured, thereby increasing concrete adhesion and improving durability.
overview
Round-shaped steel material intersects the wheel contact surface and has continuity in the direction of the running surface, providing excellent running performance, low noise, and excellent durability against wheel impact.
