[0002] Precast panels, which are the floor slabs widely used in early buildings, are indispensable modules or panels in construction projects. These precast panels are finely processed and formed in the prefabrication yard, and then directly transported to the construction site for convenient installation, hence the name precast panels.
[0003] The production process of prefabricated panels is rigorous and efficient. First, a hollow model is carefully nailed with wooden boards. Then, a steel skeleton is cleverly arranged in the hollow part of the model, and then cement is poured to fill the hollow area. After the cement is completely solidified, the wooden boards are gently knocked off, leaving behind a solid and durable prefabricated panel.
[0004] However, the currently used prefabricated concrete fences are not convenient enough to be assembled on site, and are difficult to disassemble after assembly, which results in a relatively low secondary utilization rate of prefabricated concrete panels, which is not conducive to the recycling of resources and sustainable development of the environment. Therefore, improving the convenience of splicing and disassembly of prefabricated concrete fences and enhancing the secondary utilization rate of prefabricated panels have become urgent issues to be solved in the current construction industry.
