Steel rubber Modular Expansion Joint, Brand Name : BL

We are offering modular expansion joint.　　expansion joints became an essential element of bridge construction when stone arch bridges were replaced by the beam design steel and concrete bridges. These modern bridge construction techniques led to large expansion and contraction movements and saw an increase in demands from traffic volume, weight of vehicles and riding comfort.
to meet these demands, baoli offers high quality and proven solutions. Examples of its product range include the rubber expansion joint, the modular expansion joint, and the
comb expansion joint.
Modular expansion joints
modular expansion joint systems have gained overwhelming worldwide acceptance for accommodating and sealing large joint movements on bridge structures. By incorporating the results of recent research activities, each joint system is designed to provide watertight, fatigue resistant, long-term, maintenance-free performance.
Description of modular expansion joint for bridge:
modular bridge expansion joint separates the structural elements above the basic, and sets apart appropriate gap between both sides in order to ensure the structural elements on both sides of modular bridge expansion joint free flexible in horizontal direction. The wide of sew is always 20-40mm. And then fill in thermal insulation materials.
 a) building height is low, and the structure is simple.
 b) has performance of flexible stretch and safety.
 c) has performance of easy installation for construction and low price.
