Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a waterproof structure for prefabricated buildings and a method of using the same. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled and connected using factory-standardized assembly line products as components. The factory-standardized assembly line products here refer to some concrete components pre-made in the factory, such as walls, beams, slabs, columns, balconies, stairs, etc. After these components are prefabricated, they will be transported to the construction site, where they will be assembled and connected to form the required building structure. Looking at the entire process, it can be found that it has the advantages of high overall precision, compact construction schedule, good on-site construction environment, and greatly reduced material waste. It is currently being vigorously promoted and promoted in my country.

[0003] The advantages of prefabricated buildings are obvious, but there are also some problems. As prefabricated buildings are prefabricated in the early stage and then assembled on the construction site, joints are prone to occur between prefabricated components. These joints are prone to some deformation and cracks, which in turn form water seepage channels. In the rainy season, rainwater will penetrate into the building through these channels, causing the walls to become damp and moldy, and even affecting the service life of interior decoration and furniture. Deformation and cracks at the joints will not only cause water seepage problems, but may also affect the stability of the building structure. If the deformation and cracks at the joints are too large, the connection between the prefabricated components will be weakened, threatening the stability of the entire building structure. When extreme weather or natural disasters such as earthquakes occur, the damage to the structural stability may cause the building to collapse or be seriously damaged. Summary of the invention

[0004] The purpose of the present invention is to provide a waterproof structure for prefabricated buildings and a method of using the same. When the structure is used in conjunction with the prefabricated exterior wall and the cast-in-place wall, a seamless connection is achieved, which significantly improves the safety and stability between the two, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waterproof structure for an assembled building, comprising a prefabricated exterior wall, cast-in-place wall bodies are arranged on both sides of the prefabricated exterior wall, and building sealants are arranged on the opposite sides of the prefabricated exterior wall and the cast-in-place wall body, two fireproof glues are embedded in the front sides of the prefabricated exterior wall and the cast-in-place wall body, and a sealing glue strip is arranged on one side of the fireproof glue, two backing materials are embedded in the rear sides of the prefabricated exterior wall and the cast-in-place wall body, and waterproof glue is arranged on one side of the backing material, a drainage ditch is arranged between the prefabricated exterior wall and the cast-in-place wall body, and drainage holes are arranged on the bottom and sides of the drainage ditch, two groups of first mortise and tenon blocks are fixedly connected on both sides of the prefabricated exterior wall, and two groups of second mortise and tenon blocks matched with the first mortise and tenon blocks are fixedly connected on one side of the cast-in-place wall body close to the prefabricated exterior wall, and waterproof structures are arranged on the front and rear sides of the prefabricated exterior wall and the cast-in-place wall.

[0006] Furthermore, the waterproof structure includes a waterproof layer located at the innermost side, a protective layer is arranged on one side of the waterproof layer, and a water-receiving layer is arranged on one side of the protective layer.

[0007] Furthermore, the front and rear sides of the prefabricated exterior wall and the cast-in-place wall are both provided with polymer bite-type joint tapes, which are respectively located on one side of the waterproof glue and the sealing strip, and the polymer bite-type joint tapes are compatible with the prefabricated exterior wall and the cast-in-place wall.

[0008] Furthermore, one side of the prefabricated exterior wall and the cast-in-place wall is provided with a sealing groove compatible with the fireproof glue, the sealing strip, the backing material and the waterproof glue.

[0009] Furthermore, a plurality of reinforcing ribs are provided through one side of the building sealant, and both ends of the reinforcing ribs respectively penetrate into the inner cavities of the prefabricated exterior wall and the cast-in-place wall.

[0010] A method for using a waterproof structure for an assembled building, comprising the following steps:

[0011] Step 1: Use a combination of prefabricated exterior walls and cast-in-place walls, and fix them together through the cooperation of the first mortise and tenon block and the second mortise and tenon block to form a stable wall structure, thereby ensuring the stability of the structure and providing a basis for subsequent waterproofing treatment, making the assembly process more convenient and reducing the time and difficulty of on-site construction;

[0012] Step 2: The building sealant is set on the opposite side of the prefabricated exterior wall and the cast-in-place wall, filling the tiny gap between the two and providing a preliminary sealing effect. The penetration of the reinforcing ribs further enhances the adhesion and tensile strength of the building sealant, ensuring a lasting sealing effect;

[0013] Step 3: Fireproof glue and sealing strips are embedded together in the front side of the prefabricated exterior wall and cast-in-place wall. The fireproof glue provides a fire barrier, and the sealing strips further enhance the sealing performance of the joints. The two work together to prevent fire and water;

[0014] Step 4: Backing material and waterproof glue are set on the back side of the prefabricated exterior wall and cast-in-place wall. The backing material provides structural support, and the waterproof glue further seals the joints to prevent moisture penetration;

[0015] Step 5: The waterproof layer is located on the innermost side, directly in contact with the prefabricated exterior wall and cast-in-place wall, providing basic waterproof protection. The protective layer covers the outside of the waterproof layer to protect the waterproof layer from external physical damage. The water-facing layer faces the external environment and directly resists the invasion of external moisture to form a multi-layer protection system. The polymer bite-type joint tape is set on one side of the waterproof glue and sealing strip, which is compatible with the prefabricated exterior wall and cast-in-place wall, enhancing the bite force at the joint to ensure the tightness and waterproof performance of the joint.
