[0013] The beneficial effects of the utility model are:

[0014] The utility model can provide a more secure connection mode by setting a buckle, so that the connection between the concrete precast panels is more stable and reliable. This connection mode can avoid displacement and looseness between the precast panels, improve the stability and safety of the entire structure, and the design of the buckle makes the installation process of the precast panels easier, without the need to use traditional connectors and complex construction tools, saving construction time and labor costs. By setting a waterproof layer, a thermal insulation layer, and a sound insulation layer, the concrete precast panels and the structure below them can be protected from moisture damage, extending the service life of the precast panels.
