[0002] During the construction process, due to the influence of temperature, temperature stress will be generated inside the building structure. In severe cases, cracks will appear in the components. In order to solve this phenomenon, concrete post-casting strips are usually used. Concrete post-casting strips are usually placed in relatively long buildings. After retaining the post-casting strips, the concrete can shrink freely during the construction process, significantly reducing the shrinkage stress. The tensile strength of concrete is mainly used to resist temperature stress, which increases the ability of the structure to withstand temperature changes.

[0003] The commonly used post-casting strips at present need to be measured first, scaffolding installed, and then the post-casting strips are supported by formwork. Usually, steel plates and wooden boards are used for manual formwork. This process is cumbersome, time-consuming, labor-intensive, and inefficient. Moreover, after the formwork is installed, the formwork cannot be adjusted according to the needs of the project. Since manual formwork is mostly one-time, it cannot be recycled and is troublesome to disassemble. Utility Model Content
