Description

Technical Field

[0001] The utility model belongs to the technical field of basement post-cast strip drainage, and in particular relates to a novel basement floor post-cast strip drainage structure. Background Art

[0002] Leakage is a common quality issue during construction. Among these issues, basement leakage is particularly prominent, especially in the post-cast joints of the basement floor. Since post-cast joints must be poured a second time after building settlement has stabilized and come into direct contact with the soil, effective anti-leakage measures for these joints can significantly reduce basement leakage rates, lower maintenance costs, and help maintain corporate credibility and build a strong brand.

[0003] The traditional method of plugging leaks is to organize special leak detection and plugging for the post-cast strip before pouring the floor. The floor concrete can be poured only after confirming that there is no leakage. However, due to the characteristics of the location of the post-cast strip, the stress changes in this part are large. In the later period, it is still possible that uneven settlement, stress release, etc. may cause local secondary cracks and leakage in the post-cast strip. In the later period, opening the floor, finding leaks, plugging leaks, and re-pouring are labor-intensive and material-intensive. Therefore, this application proposes a new basement floor post-cast strip hydrophobic structure to address the problem of post-cast strip leakage. Summary of the Invention

[0004] In order to solve the above-mentioned problems, the utility model provides a novel basement floor post-cast zone drainage structure, which effectively reduces the subsequent maintenance cost investment and is economical and practical.

[0005] To achieve the above objectives, the specific technical solutions of this application are as follows:

[0006] A novel basement floor post-cast strip drainage structure comprises raft slabs on both sides and a post-cast strip in the middle, wherein chamfers are provided on both sides of the post-cast strip, a water filter layer is laid in the drainage trough formed by the chamfers, a drainage pipe is provided in the water filter layer, and one end of the drainage pipe is connected to an underground water collection well; a vapor barrier layer is laid above the water filter layer, and fine stone concrete ridges are piled on both sides of the vapor barrier layer, and a floor surface leveling is poured above the raft slab and the post-cast strip.

[0007] Based on the above technical features, further, a steel mesh is laid between the fine stone concrete ridges above the vapor barrier layer to reduce the cracking of the floor in this area in the later stage.

[0008] Based on the above technical features, preferably, the joint surface between the raft slab and the post-cast strip is a roughened surface, and a water-stop steel plate is provided in the middle of the construction joint.

[0009] Based on the above technical features, preferably, the finished surface of the post-cast strip is 15-25 mm lower than the finished surface of the raft slabs on both sides.

[0010] Based on the above technical features, preferably, the water filtration layer is bluestone.

[0011] Based on the above technical features, preferably, the vapor barrier layer is a film with a thickness of not less than 0.1 mm, which effectively isolates water vapor below the floor surface and reduces the damage of water vapor to the floor.

[0012] Based on the above technical features, preferably, the vapor barrier layer covers the water filtration layer, and each side is 300 mm wider than the drainage groove.

[0013] Based on the above technical features, preferably, the fine stone concrete ridge is 100 mm wide and 30 mm thick.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This application uses a multi-layered protective structure of a water filter layer, drainage pipes, vapor barrier layer and fine stone concrete embankment to effectively construct a comprehensive waterproofing system, providing comprehensive waterproofing measures for the basement floor and post-cast zone;

[0016] A closed water filter layer is set up at the post-cast zone to drain the secondary cracks and leakage into the nearest water collection well through drainage troughs and drainage pipes to solve the problem of "drainage" of leakage water;

[0017] Laying steel mesh above the vapor barrier can effectively reduce the risk of floor cracking and provide stronger crack resistance, especially in basement environments, reducing the stress on the floor surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] It should be noted that the words "up", "down", "left", "right", "front" and "back" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] In the description of this utility model, "several" means two or more, unless otherwise specifically defined. Furthermore, the terms "mounted," "connected," and "connected" should be interpreted broadly, meaning, for example, fixed, removable, or integral; mechanical or electrical; direct or indirect through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0024] like Figure 1 As shown, an embodiment of a novel basement floor post-cast strip hydrophobic structure comprises raft slabs 1 on both sides and a post-cast strip 2 in the middle. The joint surfaces of the raft slabs 1 and the post-cast strip 2 are roughened surfaces, and a water-stop steel plate 10 is provided in the middle of the construction joint.

[0025] The finished surface of the post-cast strip 2 is 15-25 mm lower than the finished surface of the raft slabs 1 on both sides. The post-cast strip 2 is provided with chamfers on both sides, and a drainage layer 4 is laid in the drainage groove 3 formed by the chamfers. Preferably, the drainage layer 4 is made of highly permeable bluestone.

[0026] A drainage pipe 5 is provided in the water filtration layer 4. Preferably, the drainage pipe 5 is a galvanized steel pipe of φ50, and one end of the drainage pipe is connected to the bottom water collection well; the drainage pipe 5 is fixed by a clamping ring, and the laying slope of the drainage pipe 5 is not less than 3%, which is inclined higher than the water collection well.

[0027] A vapor barrier layer 6 is laid above the water filtration layer 4. Preferably, the vapor barrier layer covers the water filtration layer, and each side is 300mm wider than the drainage groove; preferably, the vapor barrier layer 6 is a film with a thickness of not less than 0.1mm, which effectively isolates water vapor below the floor surface and reduces the damage of water vapor to the floor.

[0028] Fine stone concrete ridges 7 are stacked on both sides of the vapor barrier 6. Preferably, the fine stone concrete ridges 7 are 100 mm wide and 30 mm thick.

[0029] Furthermore, after the vapor barrier layer at the post-cast zone is sealed, a steel mesh 8 is laid on top to reduce the possibility of cracking in this area later. During the laying of the steel mesh, attention should be paid to protecting the finished product to prevent the steel mesh from damaging the film. At the same time, a protective layer pad should be placed under the steel mesh to ensure that the steel mesh is located in the middle of the concrete floor to prevent cracking.

[0030] At the top, after the steel mesh 8 is laid, a floor surface 9 is poured above the raft 1 and the post-cast strip 2 for leveling. The entire post-cast strip drainage system is hidden within the floor surface. After the floor surface is poured, the overall appearance and flatness are good, which facilitates the subsequent construction of other processes such as wear-resistant or epoxy flooring.

[0031] To sum up, the novel hydrophobic structure of the post-cast strip of the basement floor provided in this application provides reliable protection for the basement structure by comprehensively considering multiple factors such as drainage, waterproofing, and crack resistance, thereby improving the durability and stability of the structure, reducing the need to open the floor, find leaks, and plug leaks in the later stage, solving the problem of labor and material waste in re-pouring, reducing the investment in later maintenance costs, and being economical and practical.

[0032] It should be noted that the drawings only illustrate the technical ideas of the present invention and cannot limit the scope of protection of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications all fall within the scope of protection of the claims of the present invention.
