Abstract
Description
Technical Field
[0001] The present application relates to the field of building waterproofing, and in particular to a basement expansion joint waterproofing structure. Background Art
[0002] Currently, there are no standards or atlases for waterproofing basement expansion joints. Most practices refer to atlases for roof expansion joints, but this can sometimes result in gaps between expansion joints being too small to be practical. This approach requires folding the waterproof layer into the expansion joint and covering it with a cover plate, which can pierce the waterproof layer during installation. Furthermore, backfilling above the basement expansion joint requires soil, and long-term moisture in the soil can cause corrosion on the cover plate, leading to leakage. This reduces the durability and safety of the structure. Utility Model Content

[0027] As mentioned in the background technology section, there are no standards or atlases for waterproofing basement expansion joints. During construction, the gaps between expansion joints are often too small to be practical. Furthermore, using a cover plate to cover the waterproof layer can cause it to pierce the layer. As the cover plate corrodes, moisture from the outside can seep into the interior through the corrosion points. Typically, backfill soil is required above basement expansion joints. Long-term moisture in the soil can cause the cover plate to corrode and leak. Leakage requires excavation and repair, resulting in high repair costs and complexity.
[0028] Figure 1Schematic diagram of a basement expansion joint waterproof structure provided by some embodiments of the present application, such as Figure 1 The present application provides a basement expansion joint waterproof structure, comprising a first retaining wall 1 and a second retaining wall 2, wherein at least a portion of the first retaining wall 1 is higher than the second retaining wall 2, and a expansion joint 3 is located between the first retaining wall 1 and the second retaining wall 2;
[0029] A first waterproof layer 4 is provided on the outside of the first retaining wall 1 and the second retaining wall 2, and a cover plate 5 is provided between the first waterproof layer 4 and the deformation joint 3;
[0030] A drainage assembly 6 is provided at the inner corner of the second retaining wall 2 , and the drainage assembly 6 is used to drain water from the inner corner.
[0031] In this embodiment, the cover plate 5 is positioned between the first waterproof layer 4 and the expansion joint 3. The first waterproof layer 4 protects the cover plate 5. This approach facilitates operation and reduces damage to the first waterproof layer 4, thereby reducing corrosion to the cover plate 5. In situations where the gap between the expansion joints 3 is too small to permit proper construction, the first waterproof layer 4 does not need to be turned inside out, thus improving construction convenience. A drainage assembly 6 is provided at the inner corner of the second retaining wall 2 to drain water from the inner corner, reducing water accumulation there. This improves the durability and safety of the engineering structure.
[0032] In the embodiment of the present application, the first retaining wall 1 can be an integral structure or a spliced structure, and the second retaining wall 2 can be an integral structure or a spliced structure.
[0033] In some optional embodiments, the cover plate 5 may include one or more of galvanized steel plates, plastic plates and aluminum plates. The cover plate 5 may be optionally galvanized steel plates, thereby reducing corrosion to the cover plate 5 and improving the waterproof effect, thereby further improving the durability and safety of the engineering structure.
[0034] The first waterproof layer 4 can be configured as one layer or as two layers. When the first waterproof layer 4 is configured as two layers, the waterproof effect of the first waterproof layer 4 can be enhanced.
[0035] In some optional embodiments, the first waterproof layer 4 may include a waterproof roll. The embodiment of the present application does not limit the thickness of the waterproof roll.
[0036] Figure 2 A schematic diagram of a basement expansion joint waterproof structure provided by another embodiment of the present application is shown in FIG. Figure 2 shown. Figure 2 The x direction is the first direction, and the y direction is the second direction. In some optional embodiments, the middle portion of the cover plate 5 may have a bent section, which is used to reduce the settlement stress of the deformation joint 3, thereby further improving the durability and safety of the engineering structure.
[0037] In some optional embodiments, the bent section may be U-shaped or V-shaped, thereby further reducing structural deformation of the cover plate 5 due to settlement.
[0038] Continue reading Figure 2 In some optional embodiments, a fixing rod 7 may be disposed between the cover plate 5 and the first waterproof layer 4 to reduce displacement of the first waterproof layer 4. Typically, the opening of the bent section faces the first waterproof layer 4, and the fixing rod 7 is disposed between the opening of the bent section and the first waterproof layer 4. In this case, at least a portion of the first waterproof layer 4 wraps around the fixing rod 7, thereby reducing structural deformation of the first waterproof layer 4 due to settlement.
[0039] For example, the fixing rod 7 may include a foam rod. The foam rod is in contact with the first waterproof layer 4, thereby further reducing the displacement of the first waterproof layer 4.
[0040] In some optional embodiments, both ends of the cover plate 5 are fixedly connected to the first retaining wall 1 and the second retaining wall 2 respectively.
[0041] In some optional embodiments, both ends of the cover plate may be fixed to the first retaining wall 1 and the second retaining wall 2 respectively by fixing nails 16. For example, the fixing nails 16 may include one or more of screws, cement nails, and nails.
[0042] The embodiment of the present application arranges the cover plate 5 between the first waterproof layer 4 and the deformation joint 3, thereby reducing the number of fixing nails 16 piercing the first waterproof layer 4, further improving the waterproof effect, and thus further improving the durability and safety of the engineering structure.
[0043] In some optional embodiments, a sealant (not shown) is provided at the connection between the cover plate 5 and the first retaining wall 1. The sealant can enhance the sealing performance between the cover plate and the first retaining wall, thereby further improving the waterproof effect.
[0044] In some optional embodiments, a sealant (not shown) is provided at the connection between the cover plate 5 and the second retaining wall 2. The sealant can enhance the sealing performance between the cover plate and the second retaining wall, thereby further improving the waterproof effect.
[0045] In some optional embodiments, the drain assembly 6 may include a drain pipe 8 .
[0046] Exemplarily, the drain pipe 8 may include, but is not limited to, a polyvinyl chloride (PVC) pipe or a polypropylene (PP) pipe.
[0047] There can be one or more drainage pipes 8 , and the number of drainage pipes 8 can be selected according to the area of the inner corner of the second retaining wall 2 .
[0048] Figure 3A schematic diagram of a drain pipe provided in an embodiment of the present application, such as Figure 3 In some optional embodiments, at least a portion of the upper portion of the drain pipe 8 may be provided with holes, and an isolation layer 9 may be provided on the outer wall of the drain pipe 8 .
[0049] The number of holes includes, but is not limited to, the following arrangements: for example, the number of holes per meter of drain pipe is greater than or equal to 20, for example, greater than or equal to 25, or greater than or equal to 30. The diameter of the holes includes, but is not limited to, the following arrangements: for example, the diameter of the holes can be 20 mm, 25 mm, or 30 mm. This can enhance the drainage effect of the drain pipe, improve the structural stability of the drain pipe 8, further improve the waterproof effect, and thus further improve the durability and safety of the engineering structure.
[0050] The embodiment of the present application provides an isolation layer 9 on the outer wall of the drain pipe 8 , thereby reducing the entry of external impurities into the drain pipe 8 , thereby further improving the drainage effect of the drain pipe 8 .
[0051] In some optional embodiments, the isolation layer 9 may include but is not limited to non-woven fabric. Wrapping the drain pipe 8 with the non-woven fabric can reduce the possibility of soil and mud clogging the drain pipe 8.
[0052] In some optional embodiments, the drain pipe may be fixed to the inner corner of the second retaining wall 2 through the hydrophobic layer 10 .
[0053] The hydrophobic layer 10 can play the role of fixing the drain pipe 8, thereby reducing the displacement of the drain pipe 8 and improving the drainage effect. In some optional embodiments, the hydrophobic layer 10 can include graded sand and gravel, and the use of graded sand and gravel as the hydrophobic layer 10 can perform secondary filtration. Along the second direction, when vegetation is planted above the deformation joint of the basement, by setting the above-mentioned hydrophobic layer 10 and the drain pipe 8, the damage to vegetation caused by a large amount of water accumulation in a low span can be reduced. It should be noted that, under normal circumstances, the inner corner of the second retaining wall 2 is at a lower position relative to the top plane of the first retaining wall 1, so the inner corner of the second retaining wall 2 is in a low span.
[0054] In some optional embodiments, the expansion joint 3 may be filled with a waterproof component 11 and / or a thermal insulation component 12 .
[0055] In the embodiment of the present application, the waterproof component 11 is sealed with the deformation joint 3, and / or the thermal insulation component 12 is sealed with the deformation joint 3, thereby improving the sealing between the deformation joints, thereby further improving the waterproof effect, and improving the thermal insulation effect.
[0056] It can be understood that the waterproof component 11 and the first waterproof layer 4 are usually tough, and the cover plate 5 can reduce the contact between the waterproof component 11 and the first waterproof layer 4, thereby reducing the deformation of the waterproof component 11 and further improving the waterproof performance.
[0057] In some optional embodiments, the waterproof component 11 may include polyurethane foam or sealant.
[0058] When the width of the deformation joint 3 is small, the waterproof component 11 may be a sealant. When the width of the deformation joint 3 is large, the waterproof component 11 may be a polyurethane foaming agent.
[0059] In some optional embodiments, the insulation component 12 may include, but is not limited to, rock wool. In addition to having insulation properties that can reduce the impact of outdoor temperature on indoor temperature, the insulation component 12 also has a fireproof function.
[0060] In some optional embodiments, the waterproof component 11 can be arranged at the deformation joint along the first direction or along the second direction. The heat preservation component 12 can be arranged at the deformation joint 3 along the first direction or along the second direction.
[0061] In some optional embodiments, the expansion joint 3 may be provided with a partition 13 along the first direction, and the partition 13 is used to fix the waterproof component 11 and / or the thermal insulation component 12. This can reduce the displacement of the waterproof component 11 and / or the thermal insulation component 12, further improving the waterproof and / or thermal insulation effects.
[0062] In some optional embodiments, the waterproof component 11 is provided along the first direction of the expansion joint 3. The partition plate 13 can be provided on one side of the waterproof component 11 or on both sides of the waterproof component 11.
[0063] In some optional embodiments, the partition 13 may include but is not limited to an extruded polystyrene board.
[0064] In some optional embodiments, a second waterproof layer 14 may be provided between the first waterproof layer 4 and the first retaining wall 1. The second waterproof layer 14 may enhance the waterproof effect of the inner corner of the first retaining wall 1.
[0065] In some optional embodiments, a second waterproof layer 14 may be provided between the first waterproof layer 4 and the second retaining wall 2. The second waterproof layer 14 may enhance the waterproof effect of the inner corner of the second retaining wall 2.
[0066] It is understandable that the inner corners of the first retaining wall 1 and / or the inner corners of the second retaining wall 2 are easily damaged, and the durability and safety of the engineering structure can be further improved by providing the second waterproof layer 14 .
[0067] In some optional embodiments, a protective layer 15 may be further provided on the outer side of the first waterproof layer 4 , and the protective layer 15 is used to protect the first waterproof layer 4 and / or the second waterproof layer 14 .
[0068] In some optional embodiments, the protective layer 15 may be a mortar brick layer.
[0069] In some optional embodiments, a covering layer (not shown) may be provided on the upper portion of the basement expansion joint waterproof structure. The covering layer may be planting soil for the growth of vegetation, or it may be ordinary backfill soil.
[0070] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
