Description

Technical Field

[0001] The utility model relates to the technical field of ramp intercepting ditches, in particular to a basement ramp intercepting ditch cover plate. Background Art

[0002] In current building design, especially in projects involving basement structures, the selection and configuration of basement ramp intercepting ditch covers are crucial to the functionality and durability of the ramp intercepting ditch.

[0003] At present, the materials for intercepting ditch covers widely used in the market mainly include cast iron grates, angle steel grates, round steel grates and reinforced concrete grates with specifications of 590 mm long x 380 mm wide. These materials have well-arranged strip drainage holes on the surface. These hollow structures effectively improve the drainage efficiency, ensuring that rainwater can quickly pass through and flow into the intercepting ditch, and then be effectively pumped out through the drainage system. However, when encountering heavy rainfall, due to the slope design of the ramp itself and the inertial impact force generated by the accumulation of rainwater, a large amount of surface rainwater or accumulated water will quickly and violently rush to the existing intercepting ditch covers at the bottom of the ramp. Although most of the water flow can be smoothly intercepted and pumped out through the strip drainage holes on these covers, some of the water flow will continue to flow along the non-hollow areas of the covers (such as frames, joints, etc.), and then penetrate or bypass the intercepting ditch and flow directly to the indoor floor of the basement.

[0004] Therefore, it is necessary to design a basement slope intercepting ditch cover plate, set multiple angle steels at certain intervals on the frame perpendicular to the direction of ramp water flow, sharply reduce the longitudinal water flow path and longitudinal water flow area on the top of the cover plate assembly, and realize the ability of the slope intercepting ditch cover plate surface to intercept water in multiple steps and quickly discharge water into the ditch, so that the surface water on the slope is not easy to flow into the indoor floor of the basement. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a basement slope intercepting ditch cover plate, on which a plurality of angle steels at certain intervals are arranged perpendicular to the direction of the ramp water flow on the frame, so as to sharply reduce the longitudinal water flow path and the longitudinal water flow area on the top of the cover plate component, thereby realizing the ability of the slope intercepting ditch cover plate surface to intercept water in multiple steps and quickly discharge water into the ditch, and the surface water on the slope is not easy to flow into the indoor floor of the basement.

[0006] In order to solve the above technical problems, the utility model provides a basement ramp intercepting ditch cover, including an intercepting ditch and a plurality of cover plate assemblies, the plurality of cover plate assemblies are laid along the length direction of the intercepting ditch; the cover plate assembly includes a frame and a plurality of angle steels, the plurality of angle steels have openings facing downward and are arranged on the frame at intervals along the direction of water flow perpendicular to the ramp, and the frame is connected to the intercepting ditch.

[0007] In at least one embodiment, the frame includes a bottom plate and a fence formed by bending and extending upward from the edge of the bottom plate, and the angle steel is arranged in the fence and fixedly connected to the bottom plate.

[0008] The utility model achieves at least the following beneficial effects:

[0009] 1. The utility model has multiple angle steels arranged at intervals on the frame along the direction of the water flow of the vertical ramp. Each angle steel acts like a miniature dam to sharply reduce the longitudinal water flow path on the top of the cover plate assembly, forcing the water flow to gradually drop between multiple levels, thereby significantly reducing the water flow speed, allowing more water to flow into the intercepting ditch, and reducing the surface water bypassing the intercepting ditch and flowing directly to the indoor floor of the basement. At the same time, this design also greatly reduces the longitudinal water flow area, making the water flow more concentrated and orderly when passing through the cover plate, and improving the water interception efficiency.

[0010] 2. The utility model adopts the angle steel with the opening facing downward, which not only reduces the water flow speed, but also the inclined surface of the angle steel has the function of guiding surface water into the intercepting ditch, thereby reducing the surface water bypassing the intercepting ditch and directly flowing to the indoor floor of the basement.

[0017] like Figure 1 to Figure 2 As shown, in one embodiment of the utility model, the basement ramp intercepting ditch cover includes an intercepting ditch 1 and a plurality of cover plate assemblies 2, and the plurality of cover plate assemblies 2 are laid along the length direction of the intercepting ditch 1; the cover plate assembly 2 includes a frame 21 and a plurality of angle steels 22, and the plurality of angle steels 22 are opened downward and are arranged on the frame 21 at intervals along the direction perpendicular to the ramp water flow, and the frame 21 is connected to the intercepting ditch 1.

[0018] The frame 21 includes a bottom plate 23 and a fence 24 formed by bending and extending the edge of the bottom plate 23 upward. The angle steel 22 is arranged in the fence 24 and fixedly connected to the bottom plate 23. The height of the angle steel 22 is lower than the height of the fence 24. The frame 21 is rectangular and the long side adopts a 590mm long L30x30x4mm hot-dip galvanized angle steel, and the short side adopts a 380mm long L30x30x4mm hot-dip galvanized angle steel. The 380mm long L30x30x4mm hot-dip galvanized angle steel and the 590mm long L30x30x4mm hot-dip galvanized angle steel are connected end to end and fully welded to form the frame 21. The wide side of the hot-dip galvanized angle steel of the frame 21 faces inward and the opening faces upward. In the frame 21, 6 angle steels 22 are arranged parallel to the long side of the frame 21. The angle steel 22 adopts L30x30x4mm hot-dip galvanized angle steel with a length of 582mm. The 6 angle steels 22 are supported on the wide surface of the L30x30x4mm hot-dip galvanized angle steel with a length of 380mm at a certain interval (spot welding on both sides) and are firmly welded (full welding) to the inner vertical surface of the L30x30x4mm hot-dip galvanized angle steel with a length of 380mm. A frame 21 with an upward opening is formed by welding multiple hot-dip galvanized angle steels, and 6 angle steels 22 are placed inside the frame 21. The non-hollow area of ​​the cover assembly 2 is smaller than the non-hollow area of ​​the iron grate, angle steel grate, round steel grate, and reinforced concrete grate. The surface water flowing to the indoor ground of the basement along the non-hollow area of ​​the cover assembly 2 (such as the frame 21, the connection, etc.) is reduced. The 6 angle steels 22 are perpendicular to the direction of the water flow, forcing the water flow to gradually descend between multiple levels, reducing the water flow speed, and allowing more water to flow into the intercepting ditch 1. At the same time, the openings of the 6 angle steels 22 face downward, and the inclined surface of the angle steel 22 has the function of guiding surface water into the intercepting ditch 1, reducing the surface water bypassing the intercepting ditch 1 and flowing directly to the indoor ground of the basement.

[0019] The intercepting ditch 1 includes a drainage ditch 11 and an installation groove 12 which are interconnected. A step 13 is formed at the connection between the drainage ditch 11 and the installation groove 12. The cover assembly 2 spans over the drainage ditch 11 and is installed on the step 13. The top surface of the cover assembly 2 is flush with the notch edge of the installation groove 12. A shock-absorbing pad strip 4 is laid on the upper surface of the step 13, and the cover assembly 2 is placed and connected with the installation groove 12 through the shock-absorbing pad strip 4. The step 13 is provided with an embedded part 3. The intercepting ditch 1 is perpendicular to the basement ramp and is set at the top and bottom of the slope. The width of the drainage ditch 11 is generally 300mm (the net width after plastering the inner wall of the ditch is 260mm). When the intercepting ditch 1 structure is constructed, a mounting groove 12 is generally reserved at the top of the ditch, and a L50x30x3mm hot-dip galvanized angle steel is embedded on the step 13 formed by the mounting groove 12 and the drainage ditch 11 (the net distance on both sides of the embedded angle steel is 390mm) to ensure that the cover plate assembly 2 is firmly, flatly and straightly installed later. Several cover plate assemblies 2 are continuously laid along the intercepting ditch 1, and a shock-absorbing pad 4 is arranged between the bottom of the cover plate assembly 2 and the embedded part 3. The shock-absorbing pad 4 adopts a rubber shock-absorbing pad to play a shock-absorbing and noise-reducing role.

[0020] All of the above embodiments are illustrative rather than restrictive. Various modifications or variations made by those skilled in the art to the above-described specific embodiments under the concept of the present utility model should all be within the protection scope of the present utility model.
