China Rubber Expansion Joint for Bridge Installation

1. Description of Bridge elastomeric expansion joints 
Expansion joints [joint expansion] refers to the gap between the structure and the structure which is affected by the expansion and contraction of the material.
Expansion joints, also known as the temperature crack is one of common noun for construction engineering. Its main function is to prevent housing due to climate change, and cracks. The approach for building the length direction along every certain distance slot reservation, buildings will be from the roof, wall, floors above ground members are disconnected, building foundation for its buried in the ground by temperature changes little influence, need not
disconnect. Telescopic seam width is generally 2 cm to 3 cm, filled the joint insulation material, the spacing of the two expansion joints in the code of building structure is clearly defined.

2. Features of Bridge elastomeric expansion joints
1.It makes bridge smooth and seamless, and it's good for preserving, cleaning and moving snow.
2.The structure is simple, no need to have special stretch frame and anchoring steel bar. Construction is convenient and fast.
3.It could absorb all kinds of deformations and shaking. And its damping property is high and it's good for bridge shock absorption.
4.Best sealing and waterproof property and anti-acid-base and corrosion.
5.Low cost of construction, durable and remarkable economic benefit and social benefit.

3.Applications of bridge elastomeric expansion joints
