Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water-stop steel plates, in particular to a socket-and-spigot type water-stop steel plate joint. Background Art
[0002] Waterstop steel plate is one of the commonly used waterproof materials in engineering. It is mainly used in reinforced concrete structures. It can change the water penetration path and extend the water penetration route. In the construction environment where the leaking water may contain corrosive components, the waterstop steel plate can play a certain role in corrosion resistance. Waterstop steel plate is generally used in the overlap area between new and old concrete. The overlap between the new and old concrete creates gaps, and the waterstop steel plate plays the role of cutting off the water penetration path.
[0003] Currently, waterstop steel plates are usually overlapped by welding, which has high requirements on overlap technology and requires construction workers to have corresponding professional skills. Therefore, a socket-type waterstop steel plate joint is needed to facilitate construction workers to carry out construction.
[0004] At present, the socket-and-spigot type waterproof steel plate joint is usually composed of a socket and a socket. The inner diameter of the socket is slightly larger than the outer diameter of the socket. The middle is filled and connected by waterproof interface materials. However, in actual use, the waterproof steel plate is buried deep in the concrete joint for a long time. After long-term use, the concrete will expand or contract under temperature changes. The expansion coefficient of the waterstop steel plate is different from that of the concrete. Under the extrusion of the concrete, gaps will appear in the interface material at the socket, reducing the waterproof effect. On the other hand, the socket-and-spigot type waterproof steel plate uses interface materials for connection at the joint. Although the interface material has certain waterproof performance, its main function is to play a connecting role. When it is exposed to penetrating water for a long time, the waterproof performance of the interface material may decrease, resulting in a decrease in the waterproof performance of the waterstop steel plate.
