Product Description

Modular Bridge Expansion Joint With Steel  Structure

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.
Structure steel type expansion joint are the most frequently employed types of expansion joints in road bridges. By special steel welding elements 
arranged side by side and equally controlled they are supported on special load carrying and control systems, intermediatesealing elements with form- and force-fit clamping as well as marked by a continuous anchorage in the structure with permanent connection to seal and coating.
Steel bridge expansion joints are used in Highway bridge decks, Service ramps, Multi- storey car parks and so on.Stainless steel bridge expansion 
joints are used to prevent buildings or bridges appear some cracks because of climate change.

Feature	-Accommodate any bridge deck expansion joint movement -A smooth transition for vehicular traffic -Durable neoprene trough to channel water away from the structure -Replaced without the need for excavation of the anchorage system -Lasts the life of the bridge deck under normal circumstances
Function	-Can expansion and contraction freely and secure.   -Comfortable driving, no noice.   -Waterproofing, can prevent rubbish and soil into the joints.

The size of steel bridge expansion joint
The expansion range contains 15 levels( from 80mm to1200mm)that can meet the requirements of various of bridges,In fact in our before orders,the highest expansion range was up to about 1700mm.
And we use EPDM rubber within the bridge expansion joint ,the suitable temperature range is from -40ºC-60ºC.
The work system of the bridge expansion joint includes three systems.Support ratation system,Waterproof sealing system and Anchorage system.
the following is  support ratation system.
we wil design and produce suitable products according your detailed drawing you need.
Bridge bearings and expansion joint are important parts of whole bridge components,  but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.
