Transflex TR50 a Transflex TR180
Transflex TR50 to Transflex TR180 (Transflex TR hereinafter) mat expansion joints for road bridges are made of a prefabricated elastomeric mat based on a vulcanized elastomer (based on NR) with metallic reinforcements. The elastic properties of the mat allow the expected movements of the structure. The mat surface is levelled with the running surface and carries the traffic loads to the bridge. The movement is allowed by the deformation of the mat.
The elastomeric mat is fixed to the bridge structure by bolts, washers and nuts.
Transflex TR are single expansion joints on the basis of shear deformation according to EAD 120110-00-0107 terminology, according to Figure 1a of EAD 120110-00-0107.
Transflex TR mat expansion joints are kits consisting of the following components:
– An elastomeric element reinforced with a bridging plate and L-brackets
– An anchorage system formed by bolts, washers and nuts
The family of Transflex TR covers the following models:
- Transflex TR50
- Transflex TR80
- Transflex TR110
- Transflex TR140
- Transflex TR180
