Bridge bearing manufacturers and manufacturers talk about the construction requirements of comb plate bridge beam expansion device

The expansion joint installation of comb-type bridge is composed of toothed steel plate, bottom supporting steel plate, angle steel and embedded reinforcement anchor. The steel plates of each layer are connected by plug welding. The supporting steel plates at both ends and the bottom layer are anchored with transition concrete and connected with the bridge deck pavement.

The basic requirements for the planning and construction of the expansion device of the comb plate bridge beam are as follows:

(1) It can adapt to the free expansion and contraction of the bridge caused by braking force, temperature change and concrete shrinkage and creep;

(2) It can adapt to the angle displacement caused by the deflection change of the bridge;

(3) Select the structure with traveling performance, which has the requirements of noise reduction, shockproof and seismic resistance;

(4) It has integrity, high rigidity and durability;

(5) Drainage and waterproof;

(6) Simple structure, convenient construction and low maintenance cost;

The above is the construction requirements for the expansion device of the comb plate bridge girder introduced by the manufacturer of the bridge bearing. If you need to know more, you can contact us or leave a message.
