Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a basement bottom slab pouring and water blocking device. Background Art
[0002] During basement construction, pouring concrete for the basement slab is a critical step. However, because basements are typically located below the groundwater level, sealing springs has long been a challenge for construction workers. This is especially time-consuming and labor-intensive when the amount of groundwater is high. During the slab pouring process, groundwater easily seeps in, affecting the concrete pouring quality and the basement's waterproofing performance. Currently, commonly used water blocking methods include high-pressure grouting or piped drainage to drains and sump pits, followed by centralized pumping. However, these methods are associated with high construction costs and poor results. Summary of the Invention
[0003] The purpose of the utility model is to provide a basement floor pouring water blocking device which is simple to manufacture, quick and convenient to install, and can effectively prevent groundwater from seeping into the basement floor during pouring to affect the pouring quality of concrete and the waterproof performance of the basement.
[0004] The purpose of this utility model is achieved in this way:
[0005] A water blocking device is used for pouring a basement floor. Before pouring the basement floor 5, an internally threaded steel pipe 1 with the same height as the floor is embedded at the water outlet position or spring 6. The water outlet position or spring is located inside or / and outside the internally threaded steel pipe. A water stop ring 4 is welded in the middle of the outer wall of the internally threaded steel pipe. The height of the water blocking screw 2 is less than the height of the floor. The external thread of the water blocking screw cooperates with the internal thread of the internally threaded steel pipe. The top axis of the water blocking screw has a threaded hole or a polygonal hole. The fastening screw 3 is dynamically matched with the inner wall of the internally threaded steel pipe. The bottom axis of the fastening screw has a small screw or a bump that cooperates with the internally threaded hole or polygonal hole on the top surface of the water blocking screw 2. The upper end of the fastening screw is connected to the handle. After tightening the water blocking screw, the fastening screw is loosened and the fastening screw is taken out. Concrete 7 seals the upper part of the internally threaded steel pipe, and the top of the concrete is flush with the top of the floor.
[0006] The thickness of concrete 7 is not less than 50mm.
[0007] When the water outlet position or the spring 6 is located outside the internally threaded steel pipe, there is a gap between the bottom surface of the internally threaded steel pipe 1 and the base of the bottom plate 5 for water to pass through.
[0008] When the water outlet position or the spring 6 is located inside and outside the internally threaded steel pipe 1 , there are small holes or slits at the bottom of the internally threaded steel pipe 1 for water to pass through.
[0009] Beneficial effects of the utility model
[0010] The utility model is simple to manufacture, quick and convenient to install, can effectively improve the construction efficiency of operators, and is more economical and practical compared with conventional water blocking methods.
[0011] The utility model significantly improves the water-stopping effect. Through the combined effect of threaded fastening design and micro-expansion waterproof fine stone concrete, the reliability of water-stopping is greatly increased, and it effectively prevents groundwater from seeping in during the bottom plate pouring process, affecting the pouring quality of concrete and the waterproof performance of the basement.
[0012] This utility model uses high-quality materials to make internally threaded steel pipes, water-blocking screws, water-stop rings and other components. They have good corrosion resistance and are not easily affected by environmental factors. They can effectively play a long-term water-blocking role and improve the durability of the basement floor.

[0016] A water blocking device is used for pouring a basement floor. Before pouring the basement floor 5, an internally threaded steel pipe 1 with the same height as the floor is embedded at the water outlet position or spring 6. The water outlet position or spring is located inside or / and outside the internally threaded steel pipe. A water stop ring 4 is welded in the middle of the outer wall of the internally threaded steel pipe. The height of the water blocking screw 2 is less than the height of the floor. The external thread of the water blocking screw cooperates with the internal thread of the internally threaded steel pipe. The top axis of the water blocking screw has a threaded hole or a polygonal hole. The fastening screw 3 is dynamically matched with the inner wall of the internally threaded steel pipe. The bottom axis of the fastening screw has a small screw or a bump that cooperates with the internally threaded hole or polygonal hole on the top surface of the water blocking screw 2. The upper end of the fastening screw is connected to the handle. After tightening the water blocking screw, the fastening screw is loosened and the fastening screw is taken out. Concrete 7 seals the upper part of the internally threaded steel pipe, and the top of the concrete is flush with the top of the floor.
[0017] like Figure 1 、 Figure 2 As shown, before pouring the basement floor 5, first, an internal threaded steel pipe 1 of the same thickness as the floor is embedded at the water outlet position or the spring 6. When pouring the basement floor, a hose is inserted into the internal threaded steel pipe 1 to drain the water to the drainage ditch. After the strength of the floor reaches the requirement, the small screw at the bottom of the fastening screw 3 is fastened with the internal threaded hole at the top of the water blocking screw 2, and then the water blocking screw 2 and the internal threaded steel pipe 1 are tightened to seal the internal threaded steel pipe 1. After tightening the water blocking screw 2, loosen and remove the fastening screw 3, and use micro-expansion waterproof fine stone concrete 7 to seal the upper part of the internal threaded steel pipe 1, and the sealing thickness is not less than 50mm.
[0018] The internal threaded steel pipe 1, the water blocking screw 2, and the water stop ring 4 are all made of stainless steel, and the surface of the fastening screw 3 is a smooth round structure.
