Description

Bridge expansion joints: The rubber strip style expansion joint devices are applicable to the highway with expansion amount ≤**0mm. BF composite plate type rubber expansion joint devices are applicable to the highway bridge with expansion amount ≤**0mm.SF three-proof expansion joint devices are used in bridges with large and medium spans. Cd, Fd, and Fm style expansion joint devices are applicable to the bridges with expansion amount ≤*0mm. GQF-MZL style expansion joint devices and XF style expansion joint devices are combinations of special-shaped steel, sealing rubber strip and displacement control system, applicable to bridge projects with expansion amount of *****0mm. Agom bridge expansion joints are structural components designed to provide smooth passage over the gap between adjacent sides of a deck joint, while also permitting relative translation and/or rotation of the two sides of a bridge deck (deck movement joint). A deck movement joint is generally defined as a structural discontinuity between two elements, at least one of which is a deck element, and is designed to allow relative translations and rotations due to: thermal expansion and contraction of the superstructure, concrete shrinkage or creep, elastic shortening due to pre-stressing, displacement of the structure under load, or any other action the desk is subjected to. Because expansion joints are installed at a late stage in construction, some of these movements will have at least partly already taken place. Consequently, expansion joints have to facilitate a smaller degree of overall movement than a bearing at the same location. Contact: Comapany name: Hengshui Baoli Engineering Plastic Co., Ltd.
