[0002] In the field of construction, composite panels usually refer to assembled composite panels made of prefabricated panels and cast-in-place steel bars, such as composite floor slabs. According to different uses and materials, composite panels can be further classified, such as decorative composite panels used for furniture and buildings, and weather-resistant and boiling water-resistant composite panels, water-resistant composite panels, and moisture-resistant composite panels based on bonding strength. With the continuous advancement of construction technology and the increasing awareness of environmental protection, composite panels, as an environmentally friendly, economical and high-performance building material, will continue to expand their application areas. In the future, composite panels will pay more attention to the recyclability and environmental protection of materials, while improving the quality and performance of products to meet the needs of different fields.

[0003] However, in the prior art, when connecting prefabricated composite panels, the two panels are simply placed together and then poured with concrete. During pouring, unstable joints may cause the composite panels to be easily deformed or damaged when subjected to force, thereby reducing their overall strength and affecting the stability of the entire structure. Unstable joints may cause the composite panels to be easily damaged during use, thereby shortening their service life. Therefore, we need a compression-resistant prefabricated composite panel.
