Expansion Joints 

     An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and
contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement
due to ground settlement or earthquakes. They are commonly found between sections of buildings, bridges, sidewalks,
railway tracks, piping systems, ships, and other structures.

Bridge Expansion Joint System       
     Bridge 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 Bridge Expansion Joint System:  
      Bridge Expansion Joint System 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  Bridge Expansion Joint System 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. 

Application of Bridge Expansion Joint System:

      Bridge Expansion Joint System is used in Highway bridge decks, Service ramps, Multi-storey car parks and so on.

It is used to prevent buildings or bridges appear some cracks because of climate change.

Construction programs of Bridge Expansion Joint System:

(1) Set out and cut Bridge Expansion Joint System.

(2) Excavate and clean the  Bridge Expansion Joint System area. 

(3) Drill holes to locate the anchor bolts.

(4) Place the rebar mat and mold. 

(5) Pour bottom concrete layer.

(6) Install comb-shaped steel plate. 

(7) Pour side concrete. 

(8) Maintenance the Bridge Expansion Joint System.

And other types expansion joints. We could produce it as customers’ requirements.
