[0002] In modern construction projects, prefabricated buildings have gradually become an industry development trend due to their many advantages such as high efficiency and environmental protection. As an important component of prefabricated buildings, concrete composite slabs are often used in conjunction with cast-in-place concrete frame beams.
[0003] However, the current connection structure between the two has many shortcomings. For example, the connection integrity is poor. When subjected to large loads or external forces such as earthquakes, cracks or even separations are prone to occur at the connection parts, affecting the overall stability of the structure. During the construction process, the positioning of the composite slab and the frame beam and the steel bar connection operations are cumbersome and difficult to ensure accuracy, increasing the construction difficulty and construction period. Furthermore, when pouring cast-in-place concrete, bubbles are prone to exist between the concrete composite slab and the concrete composite slab, and the bubbles are difficult to discharge at the bends, resulting in hollowing, which reduces the connection strength and building durability.
