[0011] This modular grating cover, through the inclusion of a water collection tray, prevents water from leaking directly down the floor when it passes through the gap between adjacent first or second steel grating panels. Since the first and second steel grating panels are attached to the first water collection tray on the support plate, the water flows towards the tray, preventing direct leakage. When water leaks through the gap between the first and second steel grating panels, the water on the first grating panel flows directly into the guide channel, while the water on the second grating panel flows through a guide plate into the channel. Because the side of the guide channel is located above the first water collection tray, the water flows through the channel onto the tray. This water collection tray achieves overall waterproofing and rainproofing for the area between the first and second steel grating panels, solving the problem of easy leakage between gaps in the cover panels and the inability to achieve overall waterproofing and rainproofing for the entire cover area.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of grating cover technology, and in particular to a spliced grating cover. Background Technology
[0002] Currently, Chinese Patent Publication No. CN115162918B discloses an openable hoisting cover and its working method, including a support frame, a cover plate, and telescopic frames rotatably disposed on the support frame on both sides of the cover plate in the vertical direction. The telescopic frames include a first connecting rod and a telescopic frame. This discloses an existing hoisting cover plate. Existing hoisting cover plates usually remove the ventilation holes on the cover plate to achieve waterproofing. Although this can achieve a certain degree of waterproofing, the gaps between the cover plates are prone to water leakage, and it is impossible to achieve overall waterproofing and rainproofing of the cover plate area. Utility Model Content
[0003] Therefore, in view of the above problems, this utility model proposes a spliced grid cover plate, which solves the above technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spliced grating cover plate, comprising a floor slab, pre-reserved holes on the floor slab, a plurality of support plates spaced apart within the pre-reserved holes, a first water collection tray on the support plates, and a first steel grating plate and a second steel grating plate filling the pre-reserved holes. The floor slab is provided with a support groove on the pre-reserved holes for contact between the first steel grating plate and the second steel grating plate. The top surfaces of the first steel grating plate and the second steel grating plate are both provided with cover plates. A water guide groove is provided on the side of the first steel grating plate near the second steel grating plate. The second steel grating plate extends along its length to above the water guide groove. A water guide plate extending downward into the water guide groove is provided on the side of the second steel grating plate near the first steel grating plate. The edges of the water guide groove and the water guide plate are located above the first water collection tray.
[0005] Furthermore, a first waterproof strip is provided between the support groove and the first and second steel grating plates.
[0006] Furthermore, a second waterproof strip is provided between adjacent first steel grating plates and between adjacent second steel grating plates.
[0007] Furthermore, the first and second waterproof strips are T-shaped.
[0008] Furthermore, a second water collection tray is provided on the water guide groove at the edge of the reserved hole.
[0009] Furthermore, the second water collection tray has the same structure as the first water collection tray. The first water collection tray has a concave groove in the middle. A steel grating is provided in the groove of the first water collection tray. The steel grating has multiple grids. The bottom of each grid has a drainage groove for water to flow from the bottom of the steel grating to one side of the first water collection tray. One side of the first water collection tray is connected to the groove and has a drainage channel for connecting to an external drainage pipe.
[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0011] This modular grating cover, through the inclusion of a water collection tray, prevents water from leaking directly down the floor when it passes through the gap between adjacent first or second steel grating panels. Since the first and second steel grating panels are attached to the first water collection tray on the support plate, the water flows towards the tray, preventing direct leakage. When water leaks through the gap between the first and second steel grating panels, the water on the first grating panel flows directly into the guide channel, while the water on the second grating panel flows through a guide plate into the channel. Because the side of the guide channel is located above the first water collection tray, the water flows through the channel onto the tray. This water collection tray achieves overall waterproofing and rainproofing for the area between the first and second steel grating panels, solving the problem of easy leakage between gaps in the cover panels and the inability to achieve overall waterproofing and rainproofing for the entire cover area.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0024] refer to Figures 1 to 10 This embodiment provides a spliced grating cover plate, including a floor slab 1, reserved holes 2 provided on the floor slab 1, a plurality of support plates 3 spaced apart in the reserved holes 2, a first water collection tray 4 provided on the support plates 3, and a first steel grating plate 5 and a second steel grating plate 6 covering the reserved holes 2. The floor slab 1 is provided with a support groove 7 on the reserved holes 2 for contact between the first steel grating plate 5 and the second steel grating plate 6. The top surfaces of the first steel grating plate 5 and the second steel grating plate 6 are both provided with cover plates 8.
[0025] The first steel grating 5 has a water guide groove 9 on one side near the second steel grating 6. The second steel grating 6 extends along its length above the water guide groove 9. The second steel grating 6 has a water guide plate 10 on one side near the first steel grating 5, extending downward into the water guide groove 9. The edges of the water guide groove 9 and the water guide plate 10 are located above the first water collection tray 4. The water guide groove 9 is U-shaped, and the water guide plate 10 is inverted U-shaped. The water guide plate 10 is fastened onto the water guide groove 9. First, the first steel grating 5 and the second steel grating 6 are laid on the support plate 3 and the floor slab 1. Between the edges, the first steel grating 5 and the second steel grating 6 are then laid on the top surface between the adjacent first water collection pans 4. This structure facilitates the splicing and assembly of the first steel grating 5 and the second steel grating 6. In actual use, the first steel grating and the second steel grating can be reinforced and fixed by binding with steel wire (not shown). The first steel grating and the second steel grating can also be reinforced by driving iron nails or bolts (not shown) into the floor slab 1 and the support plate. This fixing method is a conventional technology in this field and will not be described in detail here.
[0026] The reserved hole 2 is provided with a second water collection tray 13 on the edge of the water guide groove 9. The second water collection tray 13 can collect water that leaks from the gap between the first steel grating plate 5 and the second steel grating plate 6 and the support groove 7.
[0027] With the cover plate 8 fixedly installed on the top surface of the first steel grating 5 and the second steel grating 6, the top surface of the first steel grating 5 and the second steel grating 6 can be covered to achieve a preliminary waterproofing effect.
[0028] A first waterproof strip 11 is provided between the support groove 7 and the first steel grating plate 5 and the second steel grating plate 6. There is a certain gap between the first steel grating plate 5, the second steel grating plate 6 and the support groove 7. The first waterproof strip 11 prevents water from leaking downward from the gap between the first steel grating plate 5, the second steel grating plate 6 and the support groove 7.
[0029] A second waterproof strip 12 is provided between adjacent first steel grating 5 and adjacent second steel grating 6. The first waterproof strip 11 and the second waterproof strip 12 are T-shaped. The first waterproof strip 11 and the second waterproof strip 12 can also be I-shaped, H-shaped or other existing shapes. The T-shaped shape is easy to insert and the top can cover the gap. This shape is the optimal shape.
[0030] The first waterproof strip 11 allows for a tighter fit between the first steel grating 5 and the second steel grating 6, reducing gaps caused by manufacturing tolerances. It also seals the gaps between adjacent first steel grating 5 and adjacent second steel grating 6, guiding accumulated water through the water guide channel 9 and water guide plate 10 to the first water collection tray 4. Without the waterproof strip, the first steel grating 5 and the second steel grating 6 have multiple raised grids, which can easily cause water to drip down from the raised grids when the water volume is large. Therefore, the first waterproof strip 11 and the second waterproof strip 12 improve the overall waterproof performance.
[0031] The second water collection tray 13 has the same structure as the first water collection tray 4. The first water collection tray 4 has a concave groove 41 in the middle. A steel grating 14 is provided in the groove 41 of the first water collection tray 4. The steel grating 14 has multiple grids. The bottom of each grid has a drainage channel 141 for water to flow from the bottom of the steel grating 14 to one side of the first water collection tray 4. A drainage channel 42 for connecting to an external drainage pipe is provided on one side of the first water collection tray 4, which is connected to the groove 41.
[0032] After the water flows into the groove 41 of the first water collection pan 4, it will flow through the drainage groove 141 at the bottom of each steel grating 14 to the direction of the drainage channel 42. The drainage channel 42 can be connected to an external drainage pipe to drain the water in the first water collection pan 4. The principle of the second water collection pan 13 is the same as above, and will not be described in detail here.
