The use of expansion joints is common in Indonesia. This bridge component is designed to accommodate the movements generated by shrinkage of concrete and creep, shortening of posttensioning, thermal variations, dead and live loads, wind and seismic loads and settlement structures. Shrinkage of concrete, shortening of post-tensioning and thermal variation are generally taken into account explicitly in design calculations.
We sell the most complete expansion joints, one of which is this multi-gap finger joint. Finger joints are also called multi gaps because they have many gaps. It can be illustrated that this type of connection has a shape like the fingers on the two hands which are joined together so that it is called a finger joint. Multi-gap joints can accommodate movements starting from 75 mm. Because it is a type of open expansion joint, it requires a good drainage system at the bottom of the joint to damage the concrete layer underneath.
We accept orders for various sizes and types of expansion joint bridges in large quantities.
