Temperature-resistant leakage-proof water stop strip for bridge

CUI KAIHUI

The invention discloses a temperature-resistant leakage-proof water stop strip for a bridge, and relates to the technical field of bridge parts. The device comprises a connecting part and telescopic parts, the number of the telescopic parts is two, the telescopic parts are slidably installed on the left side and the right side of the connecting part, a telescopic assembly used for controlling the telescopic parts to move back and reset is arranged below the connecting part, and limiting assemblies used for stabilizing the position of the connecting part are arranged on the front side and the rear side of the connecting part. A recording assembly used for recording the telescopic amplitude of the telescopic part is arranged in the limiting assembly, and the connecting part and the limiting assembly are further provided with a temperature rise protection assembly used for preventing the overall temperature of the water stop strip from changing too fast. When the expansion joint of the bridge is changed due to thermal expansion and cold contraction, the expansion joint is changed through sliding of the expansion part on the connecting part, sealing of the expansion joint is kept, and compared with the mode that the expansion joint is changed through elasticity of rubber, the connecting part and the expansion part which are arranged in a separated mode cannot be damaged due to frequent deformation.

本发明公开了一种耐温式桥梁用防漏止水条，涉及桥梁零件技术领域。本发明包括连接部和伸缩部，所述伸缩部的数量为两个且滑动安装在所述连接部的左右侧，所述连接部的下方设置有用于控制所述伸缩部回移复位的伸缩组件，所述连接部的前后侧均设置有用于稳定所述连接部位置的限位组件，所述限位组件内设置有用于记录所述伸缩部伸缩幅度的记录组件，所述连接部和所述限位组件上还设置有用于防止止水条温度整体过快变化的升温防护组件。本发明当桥梁因热胀冷缩使得伸缩缝产生变化时，通过伸缩部在连接部上的滑动来顺应变化，并保持对伸缩缝的密封，相较于利用橡胶自身弹性进行变化，分离设置的连接部和伸缩部不会出现因频繁变形而破损的问题。
