[0030] As Figure 2 、 Figure 4 and Figure 5 shown, strengthening assembly 5 includes fixed block 51 arranged between horizontal steel bar 3 and vertical steel bar 4, the outer wall of fixed block 51 is fixedly provided with multiple first support rods 52, one end of first support rod 52 is fixedly connected with sleeve 53, can be stably and quickly connected with horizontal steel bar 3 and vertical steel bar 4, improve the convenience of installation, second support rod 54 is fixedly and penetrates the setting of fixed block 51, the both ends of second support rod 54 respectively penetrate concrete prefabricated slab 1 and extend and are fixedly connected with baffle 55, can provide positioning for fixed block 51, first support rod 52 and sleeve 53, so that its support is more stable.

[0031] As Figures 1 to 3 shown, the upper and lower surfaces of concrete prefabricated slab 1 are respectively provided with multiple grooves 6, and baffle 55 is located inside groove 6, can guarantee the surface flatness of concrete prefabricated slab 1, while limiting the activity range of second support rod 54.

[0032] Further, the shape of hole groove 2 is circular, oval, rectangular, trapezoidal or diamond, which can adapt to different construction scenes.

[0033] Secondly, the upper surface of the concrete prefabricated slab 1 is fixedly provided with a plurality of lifting lugs 7, so as to facilitate the transportation and hoisting of the concrete prefabricated slab 1.

[0034] Further, the transverse steel bars 3 and the vertical steel bars 4 are located at the same horizontal plane and are perpendicular to each other and cross-welded to form a grid shape, so as to greatly enhance the load-bearing capacity of the concrete prefabricated slab 1 and enable the concrete prefabricated slab 1 to reliably bear stress in various building scenes.

[0035] In addition, the reinforcing assembly 5 is arranged in an interlaced manner between the transverse steel bars 3 and the vertical steel bars 4, so that the stress can be uniformly dispersed in the entire prefabricated slab from the horizontal direction or the vertical direction, and stress concentration is avoided, and the structural strength and stability of the slotted concrete composite slab are comprehensively ensured.

[0036] The working principle of the embodiment is as follows: first, the concrete prefabricated slab 1 serves as a main structure, and a plurality of transverse steel bars 3 and a plurality of vertical steel bars 4 inside the concrete prefabricated slab 1 are perpendicular to each other and cross-welded to form a grid shape, so as to greatly enhance the overall strength of the concrete prefabricated slab 1 and enable the concrete prefabricated slab 1 to bear stress from different directions and prevent local excessive deformation or damage of the slab body during bearing.
