[0002] Post-cast strips are temporary construction joints set up in buildings. The joints are retained for a period of time according to design requirements before pouring. This "joint" solves the differential settlement between structures, shrinkage deformation of concrete, and temperature stress during the entire structural construction, achieving the purpose of not setting up permanent deformation joints. Therefore, the retention of post-cast strips during the construction process is particularly important. Post-cast strips have been included in the specifications and are widely used. They solve the problems of differential settlement between structures, shrinkage deformation of reinforced concrete, and reduction of temperature stress, and also have the functions of multiple deformation joints.

[0003] At present, when pouring in sections, the treatment method of the joints of the post-cast strips has quality risks such as cracking and leakage at the joints. There are many treatment methods for the post-cast strip segmented pouring interface. The common method is to set special joint materials at the interface when the post-cast strip concrete is poured in sections, such as rubber expansion water stop strips and asphalt strips, to ensure the sealing and waterproof performance of the interface. In addition, pre-buried steel bars can be connected or adhesives can be applied at the interface to increase the strength and stability of the interface. However, the installation and removal of formwork at the on-site joints, the roughening and cleaning of the joints are difficult, and the on-site management and supervision are not in place, resulting in multiple factors of quality risks in the construction process of the post-cast strip segmented pouring joints, and the waterproof function cannot be guaranteed. To this end, those skilled in the art provide a post-cast strip water stop steel plate to solve the problems raised in the above background technology. Utility Model Content
