[0024] This specific implementation method is a floor slab reinforcement, and its structural schematic diagram is as follows Figure 1-Figure 4 As shown, the reinforcing rib includes a V-shaped rib plate 1, and the left and right sides of the V-shaped rib plate 1 are fixedly connected with lap plates 2, the other side of the lap plate 2 is fixedly connected with a supporting rib plate 3, and the other side of the supporting rib plate 3 is fixedly connected with a bending plate 4, and multiple protrusions 5 are provided on the V-shaped rib plate 1 and the supporting rib plate 3.

[0025] like Figure 1 and Figure 2 As shown: In this embodiment, the V-shaped rib plate 1, the lap plate 2, the supporting rib plate 3 and the bending plate 4 are an integrally formed structure.

[0026] This arrangement makes it easier to manufacture the floor slab reinforcement ribs. At the same time, the one-piece formed floor slab reinforcement ribs have better strength and better overall compressive resistance.

[0027] like Figure 1 and Figure 2 As shown: In this embodiment, the V-shaped rib plate 1 includes a connecting plate 101 and two inclined plates 102 . The left and right sides of the connecting plate 101 are fixedly connected to the two inclined plates 102 , respectively. A chamfer 103 is provided between the connecting plate 101 and the inclined plates 102 .

[0028] The V-shaped rib plate 1 is arranged in this way to increase the wave distance, improve the stability of the triangular structure, reduce the setting of steel bars, improve the support strength and pressure resistance, and the chamfer 103 prevents stress concentration, thereby improving the overall strength.

[0029] like Figure 1 and Figure 4 As shown: In this embodiment, a first rib 6 is provided between the inclined plate 102 and the lap plate 2, a second rib 7 is provided between the lap plate 2 and the supporting rib plate 3, and a third rib 8 is provided between the supporting rib plate 3 and the bending plate 4.

[0030] Such arrangement of the first convex rib 6, the second convex rib 7 and the third convex rib 8 can improve the overall strength and effectively reduce the thickness of the floor slab, thereby reducing the deadweight of the structure.

[0031] like Figure 2 As shown: In this embodiment, the connecting plate 101 and the bending plate 4 are located in the same plane, and the width of the lap plate 2 is greater than the width of the bending plate 4. In this way, when used, the floor plate reinforcement ribs can be placed flat as a whole, and a narrower lap plate 2 is used to ensure the overall strength and reduce the amount of steel used.

[0032] like Figure 1 and Figure 4As shown: In this embodiment, the protrusion 5 is located on the side where the V-shaped rib plate 1 and the supporting rib plate 3 are close to each other, the protrusion 5 is a long strip structure, and the protrusion 5 is stamped integrally by the V-shaped rib plate 1 and the supporting rib plate 3.

[0033] When used in this way, the contact area between the protrusion 5 and the concrete is increased, and the concrete has a stronger shear resistance, so that the bonding ability between the floor slab and the concrete is enhanced, thereby improving the stability of the floor slab structure and enhancing the compressive strength of the floor slab body.

[0034] Working principle: Since the middle cross-section of the reinforcement is a V-shaped triangular structure, the wave pitch is increased by the V-shaped rib plate 1, and the stability of the triangular structure is better. It can not only reduce the setting of steel bars, improve the supporting strength and pressure resistance, but also effectively reduce the thickness of the floor plate while meeting the same performance requirements of the floor plate, thereby reducing the dead weight of the structure. At the same time, multiple protrusions 5 are provided on the V-shaped rib plate 1 and the supporting rib plate 3. When in use, the contact area between the protrusion 5 and the concrete is increased, and it has a strong concrete grip shear resistance, which enhances the bonding ability between the floor plate and the concrete, thereby improving the stability of the floor plate structure and enhancing the compressive strength of the main body of the floor plate.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
