Expansion Joints
Expansion joints have the demanding task of bridging the movement gaps in the carriage way and foot paths of a bridge structure.
They must be able to accommodateall the movements of the bridge without creating any constraint forces within the structure.
Simultaneously, expansion joints must be able to ensure the safety of traffic and they must maintain a continuous water tight connection
along the bridge surface.
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.
Building Expansion Joint
Building 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 Expansion Joint :
Expansion Joint separates the structural elements above the basic, and sets apart appropriate gap between both sides in
order to ensure the structural elements onboth sides of Building 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 Expansion Joint:
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 Expansion Joint:
(1) Set out and cut Expansion Joint.
(2) Excavate and clean the 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 Expansion Joint.
And other types expansion joints. We could produce them as customers’ requirements.
