Expansion Joints

Strip Seal 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, intermediate sealing 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.

Single strip expansion joint consist of two edge beams with anchorage and with elastomeric sealing element held firmly in the housing of edge beams that guarantee the water tightness the joint. The maximum gap between the edge beams at the road surface when the joint fully opens due to maximum contractions of the deck shall be limited to 80mm for comfortable passage of traffic. The edge beams protects the adjacent bridge deck concrete from damage due to vehicular impact and also transfer the vehicular loads to the deck structures through robust anchorage system.

Typical single strip seal joint is shown in the figure below.

Reinforced Elastomeric Slab Seal Expansion Joints (Movement up to 40mm to 330mm)

This type of joint consists of reinforced elastomeric pads connected to a supporting steel structure which itself is cast into the concrete structure of the bridge. The joint accommodates movements by width. Typical reinforced elastomeric joint is shown in the figure below.

Functions of Elastomeric Joints

• Should permit the expansion/contraction of the span/spans to which it is fixed with out causing any distress or vibration to the structure, Cause no inconvenience/hazard to the road user and offer good riding comfort, Should be capable of with standing the traffic loads including dynamic effects, Surface exposed to traffic should be skid free and resstant to polishing, Ensure accessibility for inspections and easy maintenance with all parts vulnerable to wear being easily replaceable

• Production Capacity: 100 Meters
• Delivery Time: 8 days
• Packaging Details: Standard ARPL packing

Bridge expansion joints are what allow the concrete to naturally expand and contract without cracking. The rubber expansion joints are placed at the end of a bridge where it meets up with the freeway. These connectors give the concrete just enough space to move and avoid concrete cracks.Bridges made of concrete will expand and contract a bit for many different reasons. That includes ice, settlement, shrinkage of the concrete, temperature changes, and even the weight of vehicles.
