Old bridges have thin floor slabs and do not have enough space to install joints. Therefore, it is not possible to install joints with low durability, or in some cases, the joint itself, and it is uneasy that the bridge bearings and main girder will be corroded by water leakage.In order to cope with the installation of joints in narrow spaces, we have developed a load support type joints that has a structure that expresses performance by anchor bolts instead of concrete adhesion, and reports the durability test results.
