Product Description

Product Description

As a moving 'living' structure, a bridge is continuously affected by vehicle load, wind conditions and temperature, which in turn contribute to its life span. Expansion joints are a vital component of any reinforced concrete, pre-stressed concrete and steel structures, and bridge decks in particular, as they absorb these movements, while also accommodating shrinkage, creep effects and changes in temperature experienced by the structure. An expansion joint is the element under the most strain in any engineering structure.

Plate-type rubber expansion joints are a commonly used expansion device in bridges and underground building structures. Rubber expansion joints are mainly used to adapt to the displacement of structures caused by temperature changes, concrete shrinkage, load effects, etc. The main features are: simple structure, economical and practical, good deformation capacity, convenient installation, simple maintenance, etc. Application scenarios of rubber expansion joints: small and medium span bridges, building structures, and roads with low traffic loads.
