[0035] Combination Figure 1 , Figure 2 and Figure 3 The first plate 100 includes a first plate body 110 and a first panel 120. The upper surface of the first plate body 110 is provided with a first flow channel 111 and a first water storage tank 112 communicating with the first flow channel 111. The first water storage tank 112 is located on the side of the first plate body 110 close to the second plate 200. The end of the first plate body 110 close to the second plate 200 is provided with a first through hole communicating with the first water storage tank 112. The first panel 120 covers the upper surface of the first plate body 110.

[0036] Specifically, the first flow channel 111 is formed on the upper surface of the first plate body 110, and includes multiple first transverse flow channels and multiple first vertical flow channels. The first transverse flow channels and the second transverse flow channels are arranged alternately. The first water storage tank 112 is formed on the upper surface of the first plate body 110 and is located on the side of the first plate body 110 near the second plate body 210. The first through hole penetrates the side wall of the first water storage tank 112 and the end of the first plate body 110 near the second plate body 210. The first panel 120 can be covered on the upper surface of the first plate body 110 by adhesive bonding, thereby sealing the upper sides of the first flow channel 111 and the second flow channel 211.

[0037] Combination Figure 1 , Figure 2 and Figure 3 The second plate 200 includes a second plate body 210 and a second panel 220. The upper surface of the second plate body 210 is provided with a second flow channel 211 and a second water storage tank 212 communicating with the second flow channel 211.

The second through hole is arranged opposite to the first through hole. The second panel 220 covers the upper surface of the second plate body 210.

[0038] Specifically, the second flow channel 211 is formed on the upper surface of the second plate body 210, and includes multiple second transverse flow channels and multiple second vertical flow channels, with the second transverse flow channels interleaved with each other; the second water storage tank 212 is formed on the upper surface of the second plate body 210 and is located on the side of the second plate body 210 close to the first plate body 110; the second through hole penetrates the side wall of the second water storage tank 212 and the end of the second plate body 210 close to the first plate body 110, and the second through hole is arranged opposite to the first through hole; the second panel 220 can be covered on the upper surface of the second plate body 210 by adhesive bonding, thereby sealing the upper side of the second flow channel 211 and the second flow channel 211.

[0039] like Figure 3 As shown, the waterproof fiberboard also includes a connector 300, which passes through the first through hole and the second through hole to connect the first board body 110 and the second board body 210.

[0040] Combination Figure 3 and Figure 4 Specifically, the connector 300 includes a screw 310 and a nut 320. The screw 310 passes through the first through hole and the second through hole, and the nut 320 is sleeved on the screw 310 to lock the first plate body 110 and the second plate body 210.

[0041] More specifically, the screw 310 passes through the first through hole and the second through hole in sequence, and the screw head of the screw 310 abuts against the side wall of the first water storage tank 112. The nut 320 is located in the second water storage tank 212 and is sleeved on the screw 310. The nut 320 abuts against the side wall of the second water storage tank 212, thereby tightening the first plate 100 and the second plate 200.

[0042] Combination Figure 4 and Figure 6 Furthermore, the connector 300 is provided with an overflow channel 311 that connects the first water storage tank 112 and the second water storage tank 212. Specifically, the overflow channel 311 is formed in the screw 310 and connects the first water storage tank 112 and the second water storage tank 212.

[0043] It should be noted that the depth of the first water storage tank 112 is greater than the depth of the first flow channel 111; the depth of the second water storage tank 212 is greater than the depth of the second flow channel 211. Furthermore, the height of the end of the overflow channel 311 near the first water storage tank 112 is higher than the bottom wall of the first water storage tank 112, and the height of the end of the overflow channel 311 near the second water storage tank 212 is higher than the bottom wall of the second water storage tank 212.

[0044] like Figure 3As shown, in some embodiments, the bottom wall of the first water storage tank 112 is provided with a first drain hole 114, and a removable first plug (not shown) is provided at the first drain hole 114; in other embodiments, the bottom wall of the second water storage tank 212 is provided with a second drain hole 213, and a removable second plug (not shown) is provided at the second drain hole 213; in still other embodiments, the bottom wall of the first water storage tank 112 is provided with a first drain hole 114, and a removable first plug is provided at the first drain hole 114, and the bottom wall of the second water storage tank 212 is provided with a second drain hole 213, and a removable second plug is provided at the second drain hole 213.

[0045] In this waterproof fiberboard, when water enters, it can flow through the first guide channel 111 into the first water storage tank 112 and / or through the second guide channel 211 into the second water storage tank 212. If one of the water storage tanks contains a large amount of water, it will flow into the other water storage tank through the overflow channel 311. Essentially, the water that has seeped into the first board 100 and the second board 200 can share the first water storage tank 112 and the second water storage tank 212, thereby improving the water storage effect. Furthermore, when there is a large amount of water in the first water storage tank 112 and the second water storage tank 212, the plug can be removed to drain the water. After the water is drained, the plug can be replaced on the drain hole. When the waterproof fiberboard of this invention is used as a rain shelter, in a long-term humid environment, if a large amount of water seeps into the waterproof fiberboard, the water can be temporarily stored in the first water storage tank 112 and the second water storage tank 212. Relevant personnel can periodically remove the plugs to drain the water from the first water storage tank 112 and the second water storage tank 212, reducing the risk of the waterproof fiberboard becoming moldy.

[0046] like Figure 4 As shown, in some embodiments, the upper surface of the first plate body 110 is further provided with a relief groove 113. The relief groove 113 penetrates the wall surface of the first water storage tank 112 opposite to the first through hole, and the relief groove 113 is opposite to the first through hole. The distance between the wall surface of the relief groove 113 opposite to the first through hole and the end of the first through hole near the relief groove 113 is greater than the length of the screw. This facilitates the screw passing through the first and second through holes.

[0047] Furthermore, an auxiliary centering part 115 is provided within the clearance groove 113. The auxiliary centering part 115 is configured to guide the screw 310 to align with the first through hole. Thus, during the process of passing the screw 310 through the first and second through holes, the auxiliary centering part 115 makes it easier to align the screw 310 with the first through hole, simplifying the operation.

[0048] Combination Figure 4 and Figure 5Specifically, the auxiliary centering portion 115 includes a first centering protrusion 1151 and a second centering protrusion 1152, which are spaced apart along a direction parallel to the bottom wall of the clearance groove 113 and perpendicular to the axial direction of the first through hole.

[0049] More specifically, the first centering protrusion 1151 and the second centering protrusion 1152 are symmetrically arranged with respect to the axis of the first through hole; the first centering protrusion 1151 has a first centering arc surface 11511, and the second centering protrusion 1152 has a second centering arc surface 11521 symmetrically arranged with respect to the first centering arc surface 11511.

[0050] In the process of using screw 310 to pass through the first through hole and the second through hole, the screw can first overlap the first pair of central arc surfaces 11511 and the second pair of central arc surfaces 11521, and then push screw 310 towards the first through hole. This process can naturally ensure that screw 310 is aligned with the first through hole, without the need for manual alignment by visual observation, which is more convenient.

[0051] In this waterproof fiberboard, when water enters, it can flow through the first guide channel 111 into the first water storage tank 112 and / or through the second guide channel 211 into the second water storage tank 212. If one of the water storage tanks contains a large amount of water, it will flow into the other water storage tank through the overflow channel 311. Essentially, the water that has seeped into the first board 100 and the second board 200 can share the first water storage tank 112 and the second water storage tank 212, thereby improving the water storage effect. Furthermore, when there is a large amount of water in the first water storage tank 112 and the second water storage tank 212, the plug can be removed to drain the water. After the water is drained, the plug can be replaced on the drain hole. When the waterproof fiberboard of this invention is used as a rain shelter, in a long-term humid environment, if a large amount of water seeps into the waterproof fiberboard, the water can be temporarily stored in the first water storage tank 112 and the second water storage tank 212. Relevant personnel can periodically remove the plugs to drain the water from the first water storage tank 112 and the second water storage tank 212, reducing the risk of the waterproof fiberboard becoming moldy.
