[0002] In the existing basement waterproof construction technology, it is usually necessary to set a waterproof roll under the structure floor. At the structure column joint, the waterproof roll is often used in the form of turning up to the structure column body, or using the waterproof roll to turn down to the structure foundation, setting a brick membrane to wrap the shallow foundation. However, the waterproof roll turning up to the structure column body will cause the structure column and the structure floor to be disconnected, thereby reducing the waterproof ability of the structure floor itself of the basement, and when the underground water pressure is too large, there will be a risk of leakage. In the case of setting a brick membrane to wrap the shallow foundation, the construction cost is high and the construction period is long, and a flexible layer is also added between the foundation structure and the foundation, thereby affecting the transmission of the structure vertical load.

The outside of the structural column 1 is sequentially provided with a hydrophobic layer 5, a cushion layer 6, a waterproof coating layer 7 and a waterproof coiled material layer 8 between a foundation top 3 and a structural bottom plate 4. The waterproof coating layer 7 can be but is not limited to a polymer cement waterproof coating layer or a non-solidified rubber asphalt waterproof coating layer. The waterproof coiled material layer 8 can also be replaced in the form of a pre-laid reverse-sticking coiled material. Figure 2 , Figure 2 The basement waterproof structure provided by the application can effectively solve the basement waterproof leakage problem, avoid the adverse effect on the load transmission of the basement structure, avoid leakage and ensure structural stability.

[0021] It should be noted that, Figure 1The uppermost shallow foundation 13 is also shown, the top plane of which is the foundation top 3 mentioned above, on which the water drainage layer 5 can be laid, which cooperates with the drainage component 12 arranged inside to drain the accumulated water, and then the cushion layer 6 is made on the water drainage layer 5, which serves to ensure the upper surface to be flat and facilitate the construction of a high-quality waterproof structure, and a waterproof coating layer 7 is coated on the cushion layer 6, which facilitates the construction of the waterproof structure, and then a waterproof roll layer 8 is laid on the waterproof coating layer 7 to realize the waterproof function. The focus of the embodiment is that the edge of the waterproof roll layer 8 is placed in the groove 9 and pressed and fixed, so that the structural floor plate 4 arranged on the upper surface of the waterproof roll layer 8 can form an integrated structure with the structural column 1, and there is no other component between the two, and the structural column 1 is integrally formed with the structural floor plate 4 from the top of the short column 2 to the top of the structural floor plate 4, which ensures the integrity of the structural floor plate, and the basement guide wall and the floor plate can be poured together to a height of 200 mm to reduce the risk of leakage. The integrated structure ensures smoother load transfer between the structural column 1 and the structural floor plate 4, and is not prone to structural problems. In addition, this structure can also ensure effective waterproofing of each part below the structural floor plate 4 to a greater extent, thereby better avoiding leakage.

[0022] As can be seen from the above description, in the embodiment of the basement floor waterproof structure provided by the application, the lower part of the structural column is a short column with a predetermined height, the cross-sectional diameter of the short column is greater than that of the upper part of the main body of the structural column, the outer part of the structural column is sequentially provided with a water drainage layer, a cushion layer, a waterproof coating layer and a waterproof roll layer between the foundation top and the structural floor plate, the top surface of the short column is provided with a groove, the edge of the waterproof roll layer enters the groove and is pressed by a pressing component, and then is fixed by a fixing component, and a drainage component is arranged in the water drainage layer, so that the waterproof effect of the foundation structure floor plate can be improved, and the structural column and the structural floor plate are integrated, so that the structural strength is higher, and the basement floor waterproof structure can avoid adverse effects on the load transfer of the basement itself while effectively solving the problem of basement waterproof leakage, thereby avoiding leakage and ensuring structural stability.

[0023] In one specific embodiment of the basement floor waterproof structure described above, further referring to Figure 2 The gap in the groove 9 can also be filled with a sealing member 14, which can fill the remaining space in the groove 9 and ensure that the structural floor plate 4 made thereon is more flat, and the sealing function ensures that there is no water leakage problem from any part of the structural floor plate 4, so the waterproof effect is better. Further, the sealing member 14 can be preferably bitumen hemp oil paste, which has better sealing effect, and of course other types of sealing substances can also be selected according to actual needs, which is not limited herein.

[0024] In another embodiment of the basement floor waterproofing structure, the pressing member 10 can be preferably an aluminum alloy strip or a stainless steel strip, both of which have high enough strength to fix the edge of the waterproofing membrane layer 8 and ensure that the edge is in full contact with the surface of the groove 9, thereby ensuring better waterproofing. On this basis, the fixing member 11 can be preferably a cement nail, which can be inserted into the groove 9 after passing through the pressing member 10 and the waterproofing membrane layer 8 by a certain distance. This not only better fixes the edge of the waterproofing membrane layer 8 in the groove 9, but also does not reduce the waterproofing effect. Of course, other types of pressing members and fixing members can also be selected according to actual needs, which are not limited herein.

[0025] In another embodiment of the basement floor waterproofing structure, the short column 2 has a cross-sectional diameter that is 10 cm to 20 cm larger than the upper cross-sectional diameter of the structural column 1. In this case, the length of the protruding part of each side of the short column 2 relative to the upper part of the structural column 1 is 5 cm to 10 cm, so that there is enough space to make a groove to accommodate the edge of the waterproofing membrane layer 8, thereby embedding the waterproofing membrane layer 8 on the short column 2, which does not affect the original structure. Of course, the size can also be adjusted according to actual needs, as long as a groove that meets the requirements can be made, which is not limited herein.

[0026] In a preferred embodiment of the basement floor waterproofing structure, the drainage layer 5 can be preferably a graded gravel layer or a pebble layer, so that the water can be organized to drain to the outside of the structure by using the drainage function of the pebble layer or the graded gravel layer itself, thereby avoiding long-term accumulation inside the structure and causing damage to the structure. Of course, other materials with drainage function can also be selected according to actual needs, which are not limited herein.

[0027] In another preferred embodiment of the basement floor waterproofing structure, a waterproof protective layer (not shown in the figure) can be provided on the upper surface of the waterproofing membrane layer 8, which can protect the waterproofing structure itself and avoid scratching the waterproofing during the subsequent construction of the structural floor 4, thereby affecting the waterproofing effect. Further, the waterproof protective layer can be preferably a cement mortar layer or a C20 concrete layer, and of course other types of protective layers can also be selected according to actual needs, which are not limited herein. Moreover, the waterproof protective layer is a preferred solution, and in some other cases, the waterproof protective layer can also not be provided.

[0028] In summary, the basement floor waterproofing structure can ensure the integrity of the whole structure, does not affect the load transfer and use performance of the original structure, does not affect the waterproofing performance of the structural floor itself, reduces the risk of leakage, and can guide the accumulated water to enter the municipal pipe network after being drained from the building through the drainage layer, thereby reducing the risk of basement leakage.
