Transflex TR270 used in Serangoon Viaduct, Singapore

Transflex

An Expansion Joint System For Bridge Decks And Flyovers

Transflex Expansion Joint system consists of moulded steel reinforced rubber modules for smooth transit between two separate bridge decks, absorbing expansion and contraction, translation and rotational movements.

The Transflex range is supplied in modules of a given length and is anchored to both sides of the structural joint. All Transflex models offer the possibility to make special pieces for kerbs, walkways, correction of skewed joint and other contours.
The rubber covers the steel reinforcement that entails a double benefit: the rubber protects the metallic part from corrosion and the steel reinforces the device structure.

FAQ

How does Transflex work?

The standard models of Transflex designed to accommodate movement by shear deformation of the elastomer between the steel components. Each model incorporates steel angles designed to be bolted to the structural deck and a steel bridging plate system which spans the open joint gap.

The high movement Transflex expansion joints have been designed to cover large movements. They consist of two modules, the movement module and the bridging module. The movement module is the ‘mobile’ section of the joint, made of rubber and steel, aimed to accommodate the expected movements. The bridging module is the ‘fixed’ section of the joint, aimed to bridge the structural opening.

What is the movement range of Transflex?

Type	Model	Movement range, mm
New Generation	Transflex TR50 to TR180	50 to 180
New Generation	Transflex TR270 to TR380	270 to 380
Standard Models	Transflex 150 to 1300	38 to 330
High Movement	Transflex 1600-3200	400 to 800
High Movement	Transflex 3600-6400	900 to 1,600
High Movement Seismic	Transflex 1600 s – 3200 s	350 to 720
High Movement Seismic	Transflex 3600 s – 6400 s	800 to 1,440

What type of movements can Transflex accommodate to?

Transflex is designed to accommodate expansion, contraction, translation and rotation movement. It also accommodates vertical and seismic movement depending on the models.
Does Transflex come in special modules?

All Transflex models offer the possibility to make special pieces for kerbs, walkways, correction of skewed joint and other contours. In this way, the continuity of the seal is ensured.
