Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rainwater drainage structure for building construction. Background Technology

[0002] Rainwater drainage during construction is a crucial part of the design and layout of drainage systems at construction sites, especially during the rainy season or in areas with heavy rainfall. This step is particularly critical as it ensures the timely removal of accumulated water during construction, maintaining a normal working environment. Rainwater drainage structures are typically used in construction site rainwater drainage operations.

[0003] In existing technologies, such as the Chinese patent with publication number CN219863165U, a construction rainwater drainage structure is proposed. A filter disc is installed above the water channel via a main board assembly of a channel cover. Rainwater collected on the ground must pass through the filter disc before flowing into the channel, thus preventing larger pieces of construction debris or stones from being washed into the channel and clogging it. However, in this drainage structure, cleaning impurities and debris from the filter disc requires first lifting the hinged cover, then using the handle to lift the filter disc, and finally emptying the debris. Since the filter disc's opening faces upwards, it is necessary to tilt the filter disc or flip it so that the opening faces downwards to empty the debris, a rather laborious process. Utility Model Content

[0004] This utility model proposes a rainwater drainage structure for building construction, which solves the problem of the laborious process of cleaning the debris in the filter disc of existing drainage structures.

[0011] The upper edges of the two frame sides are respectively provided with outward flanges, and the two flanges respectively abut against the upper edges of the two side walls of the fixed frame perpendicular to the length direction of the drainage ditch. The two frame sides and the fixed frame slide relative to each other vertically.

[0014] The fixed frame has a mounting opening on one side wall parallel to the drainage ditch and not connected to the drain plate, and the free end of the drain plate is embedded in the mounting opening.

[0015] Preferably, it also includes a lifting mechanism, which includes a mounting box, a lowering frame, and a lifting frame;

[0016] The mounting box is fixedly installed on one side wall of the drainage ditch and is located on the same side as the free end of the drain plate;

[0017] The lowering frame and the lifting frame are disposed inside the mounting box.

[0023] Preferably, a vertical pressure rod is fixed on the horizontal bar of the pressure frame, and the pressure rod passes through the top wall of the mounting box.

[0024] Preferably, the lower surface of the top wall of the mounting box is provided with a vertical anti-detachment tube, which is sleeved on the outside of the pressure rod.

[0025] Preferably, each of the two vertical rods of the lifting frame is provided with a sliding hole, the limiting slide rod passes through the two sliding holes, and the limiting slide rod slides vertically within the sliding hole.

[0026] The connecting rod has a second sliding hole on the section away from the filter frame, and a third sliding hole on the section of the connecting rod close to the filter frame.

[0027] The lower ends of the two vertical rods of the lower pressure frame are respectively hinged to the connecting rod by connecting pin one, and the two connecting pins one slide in the corresponding sliding hole two;

This makes it easy for the staff to lift the drain plate, which is simple and convenient. After lifting the drain plate, the staff lifts the filter frame using the handle, and the impurities and debris in the filter frame are also lifted out. Then, the staff uses auxiliary tools to shovel the impurities and debris out from the left and right sides of the filter frame. In this way, when cleaning the impurities and debris in the filter frame, there is no need to push the filter frame to tilt or flip it over, which saves time and effort and makes the operation convenient and quick.

[0034] 2. The anti-detachment tube can prevent the pressure rod from detaching from the top wall of the mounting box, and also serves as a guide to ensure that the pressure frame moves vertically.

[0035] 3. The sliding hole 1, in conjunction with the limiting sliding rod with a strip-shaped cross-section, can ensure that the lifting frame moves in the vertical direction, preventing the lifting frame from tilting and thus preventing the water plate from being lifted.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0046] This utility model proposes a rainwater drainage structure for building construction, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a drainage ditch 1 and a filtration and drainage mechanism 2. The filtration and drainage mechanism 2 includes a drain plate 23, a fixing frame 21, and a filter frame 22. The fixing frame 21 is fixedly installed on the top of the drainage ditch 1. The drain plate 23 has multiple drain holes 231. One side of the drain plate 23 is hinged to the side wall of the fixing frame 21 parallel to the longitudinal direction of the drainage ditch 1. Figure 1 , Figure 2 and Figure 4As shown, the filter frame 22 includes a bottom frame 222 and two vertical side frames 221. The two side frames 221 are parallel to each other and perpendicular to the side walls of the drainage ditch 1. The two side frames 221 are fixed to two opposite edges on the upper surface of the bottom frame 222. The filter frame 22 is U-shaped. Filter screens 223 are provided inside the bottom frame 222 and the two side frames 221. The upper edges of the two side frames 221 are respectively provided with outward flanges 2212. The two flanges 2212 abut against the upper edges of the two side walls of the fixed frame 21 perpendicular to the length direction of the drainage ditch 1. The two side frames 221 and the fixed frame 21 slide relative to each other vertically. The left and right sides of the filter frame 22 abut against the two side walls of the drainage ditch 1, respectively.

[0047] like Figure 3 and Figure 5 As shown, the upper edges of the two side walls of the fixed frame 21 perpendicular to the length direction of the drainage ditch 1 are respectively provided with a support groove 211. The two support grooves 211 are arranged opposite to each other, and the two flanges 2212 are respectively embedded in the corresponding support grooves 211.

[0048] like Figure 2 and Figure 5 As shown, the upper part of the shelf groove 211 is filled with sealant tape 4.

[0049] The sealant 4 can prevent soil and impurities from entering the placement groove 211 and fix the flange 2212 to the fixing frame 21, thereby ensuring that the flange 2212 can slide out of the placement groove 211.

[0050] like Figure 2 , Figure 3 and Figure 5 As shown, a mounting opening 212 is provided on the side wall of the fixed frame 21 that is parallel to the drainage ditch 1 and is not connected to the drain plate 23. The free end of the drain plate 23 is embedded in the mounting opening 212.

[0051] like Figure 4 As shown, the two side frames 221 are respectively provided with handle slots 2211 on the opposite sides.

[0052] like Figure 4 As shown, a reinforcing strip 224 is provided at the connection between the frame 221 and the bottom frame 222.

[0053] The reinforcing strip 224 can increase the connection stability between the frame 221 and the bottom frame 222, ensuring that the frame 221 is perpendicular to the bottom frame 222.

[0054] like Figure 2 As shown, the upper surface of the drainage board has a V-shaped bidirectional slope.

[0055] The drainage board has a V-shaped double slope, which can better collect rainwater and facilitate drainage.

[0056] like Figure 1 , Figure 2and Figure 7 As shown, it also includes a lifting mechanism 3, which includes a mounting box 31, a lowering frame 33, and a lifting frame 34;

[0057] The mounting box 31 is fixedly installed on one side wall of the drainage ditch 1 and is set on the same side as the free end of the drain plate 23;

[0058] The pressure frame 33 and the lifting frame 34 are installed inside the mounting box 31.

[0059] like Figure 6 As shown, a limiting slide rod 313 is fixedly connected between the two side walls of the mounting box 31 perpendicular to the length direction of the drainage ditch 1;

[0060] The cross-section of the limiting slide bar 313 is strip-shaped.

[0061] like Figure 6 As shown, rotating rods 314 are fixed on opposite sides of the two side walls of the mounting box 31, which are perpendicular to the length of the drainage ditch 1.

[0062] like Figure 6 and Figure 7 As shown, both the lower pressure frame 33 and the lifting frame 34 are inverted U-shaped, and the lower pressure frame 33 and the lifting frame 34 are connected by two connecting rods 35;

[0063] The middle part of the connecting rod 35 is rotatably connected to the rotating rod 314.

[0064] like Figure 2 , Figure 6 and Figure 7 As shown, a vertical pressure rod 32 is fixed on the horizontal bar of the pressure frame 33, and the pressure rod 32 passes through the top wall of the mounting box 31.

[0065] like Figure 6 As shown, the lower surface of the top wall of the mounting box 31 is provided with a vertical anti-detachment tube 315, which is sleeved on the outside of the pressure rod 32.

[0066] like Figure 6 , Figure 7 and Figure 8 As shown, the two vertical rods of the lifting frame 34 are respectively provided with sliding holes 341, and the limiting sliding rod 313 passes through the two sliding holes 341 and slides vertically within the sliding holes 341.

[0067] The connecting rod 35 is provided with a second sliding hole 351 on the section of the rod away from the filter frame 22, and a third sliding hole 352 on the section of the connecting rod 35 close to the filter frame 22.

[0068] The lower ends of the two vertical rods of the lower pressure frame 33 are respectively hinged to the connecting rod 35 by connecting pin 36, and the two connecting pins 36 slide in the corresponding sliding hole 351.

[0069] The lower ends of the two vertical rods of the lifting frame 34 are hinged to the connecting rod 35 by connecting pin 2 37, and the two connecting pins 2 37 slide in the corresponding sliding hole 352.

[0070] The anti-detachment tube 315 can prevent the pressure rod 32 from detaching from the top wall of the mounting box 31, and also serves as a guide to ensure that the pressure frame 33 moves in the vertical direction.

[0071] The sliding hole 341 cooperates with the limiting sliding rod 313 with a strip-shaped cross section to ensure that the lifting frame 34 moves in the vertical direction, preventing the lifting frame 34 from tilting and thus preventing the water plate 23 from being lifted.

[0072] like Figure 2 and Figure 6 As shown, the upper part of the installation box 31 near the filter frame 22 is provided with step 1 311 and step 2 312, with step 1 311 located above step 2 312.

[0073] The free end of the drain plate 23 passes through the mounting opening 212 and abuts against the step 311 and the horizontal bar of the lifting frame 34;

[0074] The side wall of the fixed frame 21 with the mounting opening 212 rests against the step 312.

[0075] Using this utility model, after rainfall, rainwater flows into the filter frame 22 through the drain hole 231 on the drain plate 23. Large impurities and garbage are blocked on the drain plate 23, while mud, small pieces of garbage, and small impurities are filtered into the filter frame 22. Rainwater then flows into the drainage ditch 1 through the filter frame 22 and is discharged away. When a large amount of impurities accumulate in the filter frame 22 and needs to be cleaned, the operator presses down the lowering rod 32, causing the lowering frame 33 to move downwards. The connecting pin 36 slides in the sliding hole 351, the connecting rod 35 tilts, and the connecting rod 35 lifts the lifting frame 34 upwards. The limiting sliding rod 313 slides in the sliding hole 341, the connecting pin 37 slides in the sliding hole 352, and the lifting frame 34 lifts the free end of the drain plate 23. This makes it easy for the operator to lift the drain plate 23. The operation is simple and convenient. After lifting 23, the filter frame 22 is lifted using the handle 2211. The impurities and debris inside the filter frame 22 are also lifted. Then, the staff uses auxiliary tools to shovel the impurities and debris out from the left and right sides of the filter frame 22. In this way, when cleaning the impurities and debris inside the filter frame 22, it is not necessary to push the filter frame 22 to tilt or flip it over, which saves time and effort and makes the operation convenient and quick. After the debris inside the filter frame 22 is cleaned, the filter frame 22 is reinserted into the fixing frame 21, and finally the drain plate 23 is covered.

[0076] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
