They can save formwork, ensure the flatness of the board surface, and are more conducive to the decoration of the finishing layer. Composite slabs are widely used in prefabricated buildings. Composite slabs need to be prefabricated according to the size of the building bay. Prefabricated composite slabs are both one of the components of the floor structure and a permanent formwork for the cast-in-place reinforced concrete composite layer.

[0022] Furthermore, a certain space is reserved between the multiple groups of prefabricated panel bodies 1, such as Figure 3 As shown, during pouring, concrete can cover the precast panel body 1 and enter the interior of the trapezoidal groove 101, increasing the contact area between the precast panel body 1 and the concrete, thereby increasing the integrity of the combination of the precast panel body 1 and the concrete, and after solidification, the concrete forms a mortise and tenon structure that matches the trapezoidal groove 101, increasing the overall strength of the concrete and the precast panel body 1, and the strength of the cast-in-place concrete after solidification is greater than the strength of the composite panel splicing, so increasing the amount of concrete by grooving the precast panel body 1 helps to improve the connection strength between multiple groups of precast panel bodies 1;

[0023] Furthermore, the triangular steel bars 105 and the external steel bars 106 can increase the connection strength between the concrete and the upper end of the precast panel body 1 during pouring.
