The introduction of bridge expansion joint

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 for
ce-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.



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.


we wil design and produce suitable products according your detailed drawing you need.

The following describes the work of the system.

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.

.
the following is waterproof sealing system




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.
