[0022] To further clarify the objectives, technical solutions, and advantages of the embodiments of this application, the following will provide a clear and complete description of the technical solutions in the embodiments of this application, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] according to Figure 1 、 2 As shown in Figures 3 and 4, a corrugated steel reinforcement member is proposed in this embodiment, including a connector 2 provided at the joint of the corrugated steel plate 1, the connector 2 including two corrugated pressing plates 21, and the corrugated steel plate 1 is placed between the two corrugated pressing plates 21;

[0024] The corrugated pressing plate 21 is wavy and fits the inner and outer sides of the corrugated steel plate 1. The corrugated pressing plate 21 is provided with a plurality of mounting holes 22, which are connected to the bolt holes 11 provided at both ends of the corrugated steel plate 1.

[0025] The two ends of the corrugated steel plate 1 are overlapped with another group of corrugated steel plates 1. The two corrugated steel plates 1 are clamped between two corrugated pressing plates 21. The corrugated pressing plates 21 are fitted with the corrugated steel plates 1. When the corrugated steel plates 1 are assembled, the bolt holes 11 at both ends of the corrugated steel plate 1 coincide with the bolt holes 11 on both ends of the other corrugated steel plate 1, and the mounting holes 22 on the corrugated pressing plate 21 coincide with the bolt holes 11.

[0026] A plurality of bolt fixings 4 are provided on the corrugated pressing plate 21. The bolt fixings 4 penetrate the corrugated pressing plate 21 and the corrugated steel plate 1. The bolt fixings 4 are threadedly connected to the mounting holes 22 and the bolt holes 11. The bolt fixings 4 are provided with nut fasteners 5 for fixing the corrugated pressing plate 21. The contact surfaces of the nut fasteners 5 and the bolt fixings 4 with the corrugated pressing plate 21 are provided with gasket protection structures.

[0027] Screw the bolt fixing part 4 into the corresponding mounting hole 22 and the bolt hole 11, tighten the nut fastener 5, and fix the corrugated pressing plate 21 to the corrugated steel plate 1. The corrugated pressing plate 21 can share the pressure of the bolt fixing part 4 and the nut fastener 5 on the corrugated steel plate 1, and protect the corrugated steel plate 1. The gasket protection structure at the connection between the corrugated pressing plate 21 and the bolt fixing part 4 and the connection between the corrugated pressing plate 21 and the nut fastener 5 can share the pressure of the bolt fixing part 4 and the nut fastener 5 on the corrugated pressing plate 21, thereby increasing the service life of the corrugated pressing plate 21 and making the connection between the corrugated steel plates 1 more firmly.

[0028] It should be noted that the arrangement direction of the corrugated pressing plate 21 is parallel to the direction of the axis of the corrugated steel plate 1 .

[0029] Regarding the bolt fastener 4:

[0030] The bolt fixture 4 includes a bolt post 43 and a bolt cap 41. The bolt cap 41 is fixedly connected to the upper end of the bolt post 43. The bolt post 43 is threadedly connected to the bolt hole 11 and the mounting hole 22. The bolt holes 11 at both ends of the corrugated steel plate 1 overlap with the bolt holes 11 at both ends of the other corrugated steel plate 1, and the mounting hole 22 on the corrugated pressure plate 21 overlaps with the bolt holes 11. After the bolt post 43 is installed on the corrugated pressure plate 21 and the bolt cap 41 is rotated, the bolt post 43 is screwed into the mounting hole 22 and the bolt hole 11.

[0031] About Nut Fastener 5:

[0032] The nut fastener 5 includes a nut 52 that fits over the outside of the bolt 43 and is threadedly connected to the bolt 43. After the bolt 43 is screwed into the mounting hole 22 and the bolt hole 11, the nut 52 is screwed onto the outside of the bolt 43 using an electric wrench. The nut 52 cooperates with the bolt cap 41 to secure the bolt hole 11 between the two corrugated pressure plates 21.

[0033] For the specific structure of the gasket protection structure, please refer to the following description.

[0034] The gasket protection structure includes a first gasket 42 and a second gasket 51. The first gasket 42 is sleeved on the outside of the bolt 43 and is fixedly connected to the lower end of the bolt cap 41. The second gasket 51 is sleeved on the outside of the bolt 43 and is slidably connected to the bolt 43.

[0035] The arc-shaped protrusion 44 is positioned between the bolt cap 41 and the corrugated plate 21, and the second gasket 51 is positioned between the nut 52 and the corrugated plate 21. This disperses the pressure between the bolt cap 41, the nut 52, and the corrugated plate 21, reducing wear and scratches at the direct contact points. This maintains the smoothness and integrity of the connected components, facilitating subsequent maintenance and servicing.

[0036] The outer side wall of the corrugated pressing plate 21 is a smooth curved surface. To allow the arc-shaped protrusion 44 to fit the outer side wall of the corrugated pressing plate 21 , the lower end surface of the first gasket 42 is an arc-shaped protrusion 44 that fits the corrugated pressing plate 21 .

[0037] To ensure that the horizontal surface 54 can mate with the outer wall of the corrugated platen 21, the upper end surface of the second gasket 51 is formed into an arc-shaped groove 53 that mates with the outer wall of the corrugated platen 21, and the lower end surface of the second gasket 51 is formed into a horizontal surface 54. This design has the advantage that the nut 52, which is screwed onto the outer side of the bolt 43, can be in close contact with the lower end surface of the horizontal surface 54, thus improving the fit between the nut 52 and the second gasket 51.

[0038] How this application works:

[0039] The two ends of the corrugated steel sheet 1 are overlapped with another set of corrugated steel sheets 1. The two corrugated steel sheets 1 are sandwiched between two corrugated pressing plates 21. The corrugated pressing plates 21 are in contact with the corrugated steel sheets 1. When the corrugated steel sheets 1 are assembled, the bolt holes 11 at both ends of the corrugated steel sheet 1 coincide with the bolt holes 11 at both ends of the other corrugated steel sheet 1, and the mounting holes 22 on the corrugated pressing plate 21 coincide with the bolt holes 11. The bolt holes 11 at both ends of the corrugated steel sheet 1 coincide with the bolt holes 11 at both ends of the other corrugated steel sheet 1, and the mounting holes 22 on the corrugated pressing plate 21 coincide with the bolt holes 11. The bolt post 43 is installed on the corrugated pressing plate 21. The bolt cap 41 is rotated, and the bolt post 43 is screwed into the mounting holes 22 and bolt holes 11. After the bolt 43 is screwed into the mounting hole 22 and the bolt hole 11, use an electric wrench to screw the nut 52 onto the outside of the bolt 43. The nut 52 cooperates with the bolt cap 41 to fix the bolt hole 11 between the two corrugated pressure plates 21. The corrugated pressure plate 21 can share the pressure of the bolt fixing part 4 and the nut fastener 5 on the corrugated steel plate 1, and protect the corrugated steel plate 1. The gasket protection structure at the connection between the corrugated pressure plate 21 and the nut fastener 5 can share the pressure of the bolt fixing part 4 and the nut fastener 5 on the corrugated pressure plate 21, thereby improving the service life of the corrugated pressure plate 21 and making the connection between the corrugated steel plates 1 more firm and with higher connection strength.
