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