Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically, to a waterproof structure for precast concrete exterior walls of assembled buildings. Background Art

[0002] In contemporary China, as a cutting-edge representative of modern building technology, assembled buildings are driving the construction industry towards higher quality and efficiency with their unique charm; however, the joints between components in this building mode have become a key challenge for waterproof performance; under extreme weather conditions, the vulnerable protection at these joints may be mercilessly breached by rainwater, forming accumulated water that is difficult to quickly disperse; this situation will not only induce an increase in humidity inside the wall panels, accelerating the deterioration of materials, but long-term immersion may also erode the metal structure behind the wall panels, directly threatening the overall safety and service life of the building structure; given the waterproof challenges faced by assembled buildings, it is particularly important to design a waterproof structure for precast concrete exterior walls of assembled buildings; by adopting a waterproof structure, not only can the durability and safety of assembled buildings be greatly improved, but also the sustainable development of the entire construction industry can be promoted.

[0003] For example, Chinese Patent CN218861788U discloses a waterproof structure for precast concrete exterior wall panels of assembled buildings, including a vertical drainage line, a rubber airtight strip, a horizontal drainage line, a centralized drainage line, a drain pipe, an exterior wall panel, a rabbet structure, a caulking agent, a foam strip, and a water guide pipe; through multiple waterproof measures and drainage paths, it is ensured that rainwater can be effectively drained, avoiding accumulation at the bottom end of the wall panel, thereby protecting the wall structure from water damage. However, during the drainage process of the above waterproof structure, since the drainage line is a traditional straight line, water cannot be quickly guided to the drain pipe for discharge, increasing the residence time of water near the wall. When encountering a large amount of drainage, it may not be able to quickly discharge a large amount of water, resulting in water accumulation on the wall, increasing the risk of damage to the wall structure.

[0004] Regarding the problems in the related technology, no effective solutions have been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related technology, the utility model proposes a waterproof structure for precast concrete exterior walls of assembled buildings to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] Therefore, the specific technical solution adopted by the utility model is as follows:

[0007] An assembled concrete precast exterior wall waterproof structure includes several precast exterior wall panels. A horizontal drainage mechanism is arranged between the top ends of a group of precast exterior wall panels and the bottom ends of the adjacent precast exterior wall panels. A vertical drainage mechanism is arranged between one ends of a group of precast exterior wall panels and one ends of the adjacent precast exterior wall panels. A drain pipe is inserted through the bottom of one side of the lowermost precast exterior wall panel.

[0008] Further, in order to improve the waterproof performance of the precast exterior wall, under the guiding action of the waterproof upper slope and the waterproof lower slope, it can avoid rainwater directly vertically impacting the horizontal gap of the wall panel, reducing the chance of water retention and penetration; and under the guiding action of the guiding groove on the water flow, it can ensure that rainwater can quickly drain into the vertical drainage mechanisms at both ends of the precast exterior wall panel along a predetermined direction, avoiding water accumulation in the horizontal gap of the precast exterior wall panel, reducing the erosion of water on the wall body and the connection structure. At the same time, the guiding groove with a gradually increasing diameter can reduce the resistance of the water flow, ensuring that even under heavy rain conditions, the drainage can be carried out smoothly, thereby improving the drainage efficiency and stability, and further ensuring the waterproof performance at the horizontal gap of the precast exterior wall panel. The horizontal drainage mechanism includes a waterproof upper slope arranged at the bottom ends of a group of precast exterior wall panels. The bottom end of the waterproof upper slope is provided with a matching waterproof lower slope. A guiding groove is opened between the waterproof upper slope and the waterproof lower slope; a dividing line one is arranged in the middle of the guiding groove, and the diameters of both ends of the guiding groove gradually increase along the direction away from the dividing line one, so that the guiding groove forms a flat end face.

[0009] Further, in order to accelerate the discharge of water flow and reduce the noise generated by the water flow, under the action of the thread groove, it can guide the water flow to form a vortex, accelerate the flow of water, disperse the energy of the water flow, reduce the direct impact sound and turbulence sound of the water flow. At the same time, under the action of several convex blocks, the water flow can be further dispersed, reducing the reflection and resonance of sound waves in the pipeline, further reducing the noise level. Among them, under the action of the thread groove and the convex blocks, the water flow can effectively wash away the sediments and dirt on the pipeline wall, reducing the risk of blockage; and under the action of the special structure of the drainage groove, it can provide additional structural support, enhance the strength and stability of the pipeline, and can better adapt to different flow conditions. Even when the flow rate changes greatly, it can accelerate the water flow rate and maintain a low noise level. The vertical drainage mechanism includes a fitting surface one arranged at one end of a group of precast exterior wall panels. One side of the fitting surface one is provided with a matching fitting surface two. A drainage groove is opened between the fitting surface one and the fitting surface two. Thread grooves are arranged at the top and bottom of the inner wall of the drainage groove. Several convex blocks are arranged in the middle of the inner wall of the drainage groove; a dividing line two is arranged in the middle of the drainage groove, and the diameters of the top end and the bottom end of the drainage groove gradually decrease along the direction away from the dividing line two, so that the drainage groove forms a flat end face; the several convex blocks are evenly arranged and distributed in a circular pattern in the middle of the drainage groove; the drain pipe is communicated with the lowermost drainage groove.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the coordinated setting of the horizontal drainage mechanism, the vertical drainage mechanism and the drain pipe, the waterproof ability of the precast exterior wall is significantly improved, so that rainwater can no longer directly vertically impact the horizontal joints of the wall panel, greatly reducing the possibility of water retention and penetration at the joints; in addition, the drainage speed of water flow is also increased, while suppressing the noise generated during the drainage process, ensuring that the water flow can be discharged quickly and quietly, avoiding the formation of water accumulation, thus significantly enhancing the drainage efficiency and the overall stability of the waterproof structure, and further ensuring the waterproof performance of the precast exterior wall.

[0012] 2. By setting the horizontal drainage mechanism, under the guiding action of the waterproof upper inclined plane and the waterproof lower inclined plane on the water flow, it can avoid rainwater directly vertically impacting the horizontal joints of the wall panel, reducing the chance of water retention and penetration; and under the guiding action of the guiding groove on the water flow, it can ensure that rainwater can quickly drain into the vertical drainage mechanisms at both ends of the precast exterior wall panel along the predetermined direction, avoiding water accumulation in the horizontal joints of the precast exterior wall panel, reducing the erosion of water on the wall body and the connection structure. At the same time, the guiding groove with a gradually increasing diameter can reduce the resistance of the water flow, ensuring that even under heavy rain conditions, the drainage can be carried out smoothly, thereby improving the drainage efficiency and stability, and further ensuring the waterproof performance at the horizontal joints of the precast exterior wall panel.

[0013] 3. By setting the vertical drainage mechanism, under the action of the threaded groove, it can guide the water flow to form a vortex, accelerate the flow of water, disperse the energy of the water flow, reduce the direct impact sound and turbulent sound of the water flow, and at the same time, under the action of several convex blocks, the water flow can be further dispersed, reducing the reflection and resonance of sound waves in the pipeline, further reducing the noise level. Among them, under the action of the threaded groove and the convex blocks, the water flow can effectively wash away the sediments and dirt on the pipeline wall, reducing the risk of blockage; and under the action of the special structure of the drainage groove, it can provide additional structural support, enhance the strength and stability of the pipeline, and can better adapt to different flow conditions. Even when the flow rate changes greatly, it can accelerate the water flow rate and maintain a low noise level. Description of the Drawings
