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. With the BAOLI modular expansion joints, several lamellas divide the total movement of a bridge gap into passable single gaps, which are
locked to each other by water-tight elastomeric profiles.

 B. Low noise and wear resistant constructions with long lasting durability are the results of the highly developed design, based on the principles of elastic bearing and steering system.

C. BAOLI modular expansion joints can be constructed for any big movements - from about 0 mm to 1200 mm and more. They allow movements in all 3 dimensions as well as constraint-free rotations around all 3 axes.

D. All parts subject to wear and tear can be replaced quickly and easily at any time.

E. BAOLI modular expansion joints are low-maintenance constructions with a long lasting durability.

 
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.

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