[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] For example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a crack-resistant concrete slab, comprising a concrete layer 1 and a reinforcing structure 2 embedded in the concrete layer 1, wherein the number of the reinforcing structure 2 is at least one; Figure 1 As shown, the number of the reinforcing structure 2 is one; specifically, the reinforcing structure 2 includes two first reinforcing rods 3, each of the first reinforcing rods 3 includes a plurality of first arc-shaped rods 31, and the plurality of first arc-shaped rods 31 are arranged in parallel and evenly distributed; and a second arc-shaped rod 32 is arranged between two adjacent first arc-shaped rods 31; at the same time, the two first reinforcing rods 3 are arranged symmetrically; a second reinforcing rod 4 is arranged above each of the two first reinforcing rods 3, and the structure of the second reinforcing rod 4 is the same as that of the first reinforcing rod 3, and each first reinforcing rod 3 is arranged opposite to the second reinforcing rod 4 above it, that is, the second reinforcing rod 4 is composed of a plurality of first arc-shaped rods 31 and a plurality of second arc-shaped rods 32.

[0025] The structures of the first curved rod 31 and the second curved rod 32 are also the same, and the first curved rod 31 and the second curved rod 32 in the first reinforcing rod 3 are arranged in opposite directions; that is, the first curved rod 31 and the second curved rod 32 are semicircular arc rod structures. Since the second curved rod 32 is arranged between two adjacent first curved rods 31, the first reinforcing rod 3 and the second reinforcing rod 4 both have a serpentine curved structure, so the area covered by the first reinforcing rod 3 and the second reinforcing rod 4 on the concrete layer 1 can be increased, thereby improving the tensile performance of the concrete layer 1.

[0026] The first curved rod 31 in each first reinforcing rod 3 is correspondingly arranged with the first curved rod 31 in the second reinforcing rod 4 above the first reinforcing rod 3; the second curved rod 32 in each first reinforcing rod 3 is also correspondingly arranged with the second curved rod 32 in the second reinforcing rod 4 above the first reinforcing rod 3; a connecting component 5 is provided between the corresponding two first curved rods 31, and a connecting component 5 is also provided between the corresponding two second curved rods 32; and as shown in FIG. Figure 2 As shown, the multiple connecting components 5 corresponding to each first reinforcing rod 3 are arranged in parallel and at intervals.

[0027] The connecting assembly 5 includes a support tube 51, and a plurality of first support rods 52 are evenly distributed circumferentially on one end of the support tube 51, and a plurality of second support rods 53 are evenly distributed circumferentially on the outside of the support tube 51; the support tube 51 corresponding to the first arc rod 31 is coaxially arranged inside the upper first arc rod 31, and the support tube 51 corresponding to the second arc rod 32 is coaxially arranged inside the upper second arc rod 32, and the outer diameter of the support tube 51 is smaller than the inner diameter of the first arc rod 31 and the second arc rod 32.

[0028] And as Figure 2 As shown, a portion of the first support rod 52 on the corresponding support tube 51 inside each first curved rod 31 above is connected to the first curved rod 31 located below, and a portion of the second support rod 53 on the corresponding support tube 51 inside each first curved rod 31 above is connected to the first curved rod 31; similarly, a portion of the first support rod 52 on the corresponding support tube 51 inside each second curved rod 32 above is connected to the second curved rod 32 located below, and a portion of the second support rod 53 on the corresponding support tube 51 inside the second curved rod 32 above is connected to the second curved rod 32.

[0029] The first support rod 52, the second support rod 53 and the support tube 51 can be fixed by welding, and the first support rod 52 and the first curved rod 31 and the second curved rod 32 can be fixed by welding or connected by steel wire; the second support rod 53 and the first curved rod 31 and the second curved rod 32 can be fixed by welding or connected by steel wire.

[0030] The first arc rod 31 , the second arc rod 32 , the first support rod 52 , the second support rod 53 and the support tube 51 are all made of metal, such as steel.

[0031] The second support rod 53 is composed of a cross rod 531 and an oblique rod 532. An arc transition is provided at the connection between the cross rod 531 and the oblique rod 532. The first support rod 52 and the oblique rod 532 are both inclined. The corresponding two first arc rods 31 are connected to the support tube 51 through the first support rod 52 and the second support rod 53 respectively, and the corresponding two second arc rods 32 are also connected to the support tube 51 through the first support rod 52 and the second support rod 53 respectively, thereby improving the supporting strength of the first reinforcement rod 3 and the second reinforcement rod 4. At the same time, the connecting component 5 is pre-buried in the concrete layer 1, and the first support rod 52 and the oblique rod 532 are inclined in the concrete layer 1. The first support rod 52 and the oblique rod 532 on each support tube 51 are evenly distributed around the circumference, thereby further improving the tensile performance of the concrete layer 1, thereby improving the overall anti-cracking effect.

[0032] In this embodiment, the first reinforcing rod 3 and the second reinforcing rod 4 have a serpentine curved structure, which can increase the area covered by the first reinforcing rod 3 and the second reinforcing rod 4 on the concrete layer 1. At the same time, the first support rod 52 and the diagonal rod 532 are arranged obliquely in the concrete layer 1, greatly improving the overall anti-cracking effect.

[0033] Example 2, refer again Figure 1 、 Figure 2 and Figure 5 This embodiment is based on the first embodiment, and a connecting tube 54 is coaxially arranged at one end of each support tube 51 away from the first support rod 52; the connecting tube 54 is fixedly connected to the support tube 51, and the connecting tube 54 can be made of steel, and the connecting tube 54 and the support tube 51 can be fixed by welding; since the multiple connecting components 5 corresponding to each first reinforcing rod 3 are arranged in parallel and spaced apart, the multiple connecting tubes 54 corresponding to each first reinforcing rod 3 are also arranged in parallel and spaced apart; since the connecting tube 54 is a cylindrical structure, that is, it has a through hole 541, the installation and positioning of the concrete slab can be facilitated by the connecting tube 54.

[0034] In addition, a through hole 541 is provided on each connecting tube 54, and the axis of the through hole 541 is perpendicular to the axis of the connecting tube 54; Figure 2 As shown, several through holes 541 corresponding to each first reinforcing rod 3 can be passed through a column, so that when the concrete slab is poured, the connection assembly 5, the first reinforcing rod 3 and the second reinforcing rod 4 can be conveniently suspended inside the prefabricated formwork by supporting and limiting the column, and when pouring concrete, the upper end of the support tube 51 can be just submerged. After pouring and forming, the entire concrete slab can be lifted and moved by the column, and the column can be removed from each through hole 541; therefore, the concrete molding operation and the movement after molding are convenient.
