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.

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. 

Application of Modular Expansion Joint for Bridge:

Modular Bridge Expansion Joint 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 Modular Expansion Joint for Bridge:

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

(2) Excavate and clean the Modular Bridge Expansion Joint 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 Modular Bridge Expansion Joint.

Determination of the amount of the bridge expansion device

       Bridge expansion joint specification decided by the expansion account will directly impact the using effect of the flexing device. At the
same time, the interval of beam and board must be considered in order to ensure the anchoring of the expansion joint and beam, board and
achieve the best effect.
       Therefore we must leave sufficient allowance to guarantee the effect and durability when we choose the specifications of the expansion
joints.

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