Water-stop belt structure for bridge expansion joint

GONG LAQING / PAN YUNLEI / HUANG SHUAI

The invention relates to the technical field of water-stop belts, in particular to a water-stop belt structure for a bridge expansion joint, which comprises two pieces of profile steel, rails are arranged in the profile steel, the rails are connected with a cross beam through limiting blocks, the inner side of the cross beam is connected with a water-stop belt through clamping blocks, and screws are arranged on the edges of the clamping blocks. And a metal plate is mounted on the upper surface of the water stop belt on the upper side. After the structure is used for a long time, rainwater and slurry cannot be accumulated on the water-stop belt, the water-stop belt cannot be eroded, the waterproof effect is good, the service life is long, and use is convenient and efficient.

本发明涉及止水带技术领域，特别是一种桥梁伸缩缝用止水带结构，包括两个型钢，所述型钢内开有轨道，所述轨道通过限位块与横梁连接，所述横梁内侧通过夹块与止水带连接，所述夹块的边缘设有螺丝，上侧的所述止水带上表面安装有金属板。本发明可以在长时间使用后，雨水及泥浆不会堆积在止水带上，不会造成侵蚀止水带，防水效果好，使用寿命长，使用便捷高效。
