Description

Technical Field

[0001] The utility model relates to the technical field of green building waterproofing, in particular to a waterproof structure at the connection between a basement floor and a side wall. Background Art

[0002] Green buildings, during their entire life cycle, save resources, protect the environment, reduce pollution, provide people with healthy, applicable, and efficient use of space, and maximize the realization of high-quality buildings that are in harmony with nature. At present, during the construction of basements in green buildings, the connection between the floor and the side wall is a weak link in waterproofing. People usually use the method of adding waterproof membranes or applying waterproof coatings at the connection between the floor and the side wall to strengthen waterproofing.

[0003] The above traditional waterproofing methods are difficult to ensure the continuity and stability of the waterproof layer when constructing the connection between the basement floor and the side wall. For example, the connection between adjacent waterproof membranes may cause seepage and leakage due to loose adhesion. At the same time, due to the limitations of materials and construction methods, the long-term waterproofing effect is often not ideal. Utility Model Content

[0004] The utility model provides a waterproof structure for the connection between the basement floor and the side wall. The specific technical scheme is as follows:

[0005] A waterproof structure for the connection between a basement floor and a side wall comprises a floor, a side wall cast on the top of the floor, and a waterproof mechanism arranged between the floor and the water-facing surface of the side wall, the waterproof mechanism comprising a first waterproof roll fixedly arranged on the top of the floor, and a second waterproof roll fixedly arranged on the water-facing surface of the side wall, the top end of the first waterproof roll extending to the water-facing surface of the side wall, the bottom end of the second waterproof roll extending to the top of the first waterproof roll of the floor, a pressure plate is provided at the connection between the floor and the side wall, and a plurality of hemispherical blocks are fixedly provided on the outer wall of the pressure plate for improving the connection strength of the first waterproof roll and the second waterproof roll by top pressure.

[0006] By adopting the above technical solution, the first waterproof membrane and the second waterproof membrane can be more firmly attached through the top pressure of the pressing plate and the hemispherical block, thereby ensuring the continuity and stability of the waterproof structure such as the waterproof membrane.

[0007] Optionally, a construction joint is formed at the bottom end of the side wall, and a waterstop is provided inside the side wall for stopping water from the construction joint. A first waterproof layer is fixed between the bottom plate, the side wall and the outer wall of the waterproof mechanism, and the pressure plate and several of the hemispherical blocks are located inside the first waterproof layer.

[0008] By adopting the above technical solution, the first waterproof layer can be formed by the solidification of the waterproof mortar after pouring to further waterproof the connection between the bottom plate and the side wall, and the first waterproof layer formed after solidification will fix the pressure plate and the hemispherical block.

[0009] Optionally, a permanent protective wall is fixedly provided on the water-facing surface of the first waterproof layer of the base plate, a temporary protective wall is fixedly provided on the top of the first waterproof layer on one side close to the permanent protective wall, a fine stone concrete protective layer is fixedly provided between the top of the first waterproof layer of the base plate and the temporary protective wall, and a second waterproof layer is fixedly provided between the water-facing surface of the first waterproof layer of the side wall and the top of the fine stone concrete protective layer.

[0010] By adopting the above technical solution, the permanent protection wall and the temporary protection wall can provide certain protection for the water-facing surface of the basement floor, making it difficult for water to seep in and leak into the floor.

[0011] Optionally, a concrete base layer is fixedly provided between the bottom of the first waterproof layer of the base plate and the bottom of the permanent protective wall, and a cushion layer is fixedly provided at the bottom of the concrete base layer.

[0012] By adopting the above technical solution, the cushion layer can be a soil layer of the foundation, and the concrete base layer formed by pouring can stably support structures such as the bottom plate on the cushion layer.

[0013] In summary, the present invention has at least one of the following beneficial effects:

[0014] 1. Through the setting of multiple waterproof structures such as the first waterproof membrane, the second waterproof membrane and the first waterproof layer, the waterproof performance of the connection between the basement floor and the side wall can be improved, the long-term waterproof effect is good, and the probability of using mechanical equipment for repair due to leakage in the later period is reduced. It is energy-saving and convenient, and the first waterproof membrane and the second waterproof membrane can be more firmly attached through the top pressure of the pressure plate and the hemispherical block, thereby ensuring the continuity and stability of waterproof structures such as waterproof membranes.

[0015] 2. The construction joint can be waterproofed by the waterstop, so that the outer surface of the hemispherical block is an arc surface, which can reduce the contact area between itself and the first waterproof membrane and other waterproof mechanisms, which can not only increase the top pressure on the waterproof mechanism, but also not easily damage the first waterproof membrane and other waterproof mechanisms, which is convenient and practical.

The bottom plate 1 and the side wall 11 are the basement bottom plate and side wall of the green building respectively. The waterproof mechanism can waterproof the connection between the bottom plate 1 and the water-facing surface of the side wall 11. Figure 1 The area pointed by the middle arrow is the water-facing surface.

[0021] Reference Figure 1 A construction joint 12 is formed at the bottom end of the side wall 11, and a waterstop 13 for water-stopping the construction joint 12 is arranged inside the side wall 11. The side wall 11 is cast in sections due to existing design requirements or construction needs, and the construction joint 12 is a joint formed between the concrete cast first and the concrete cast later. The upper and lower ends of the waterstop 13 are bent and tilted toward the outside, which can effectively block the water penetrating inward. This is a public technology that can stop and waterproof the construction joint 12.
