Product Description

Product Description

   Rubber expansion joint is an elastic connection device used for bridges, buildings, pipelines and other structures. It is mainly used to absorb displacement caused by temperature changes, concrete shrinkage, load deformation, etc., and also has waterproof, dustproof and noise reduction functions.


Structure

Characteristic

Characteristic 1
      Elastic deformation: Adapt to the multi-directional displacement (expansion, shear, torsion) of the structure.

Characteristic 2
    Durability: resistant to aging and corrosion, able to withstand repeated vehicle loads, with a long service life.
   

Characteristic 3
  Waterproof and dustproof: Apply adhesive to the bolt holes at the bottom of the expansion joint and every meter of assembly to ensure good sealing performance and prevent impurities from entering.

 

Characteristic 4
    Low maintenance: Installation and replacement are extremely convenient, without frequent maintenance, and the lifespan can reach 10-20 years.
