Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproofing technology for underground engineering construction, and in particular to an installation and fixing structure for a centrally embedded steel-edged rubber waterstop. Background Technology
[0002] Steel-edged rubber waterstops are composite waterproofing materials. They mainly consist of two parts: rubber and steel edges. The rubber part typically uses natural rubber or neoprene rubber, materials with good elasticity and sealing properties. This type of rubber can withstand a certain degree of tension, compression, and deformation, and has excellent resistance to aging, ozone, and chemical corrosion. The steel edge is generally made of galvanized steel strip. This steel strip enhances the overall strength of the waterstop, ensuring it maintains good shape and stability during installation and use, and effectively fixes the waterstop's position. Steel-edged rubber waterstops are mainly used in expansion joints and construction joints of waterproofing projects such as underground structures, dams, and pools. In these areas, the elasticity of the rubber part adapts to structural deformation, preventing leakage of groundwater, rainwater, and other water bodies. Simultaneously, the steel edge ensures that the waterstop maintains its waterproofing function even under significant external forces, greatly improving the reliability of the waterproofing project.
[0003] A search revealed Chinese patent publication number CN207512793U; this utility model provides a device for installing and fixing a centrally embedded steel-edged waterstop. It includes an upper positioning template and a lower positioning template positioned above and below the steel-edged rubber waterstop. Square timbers arranged along the length of the waterstop are fixedly placed near the base of the upper and lower positioning templates. The two timbers are fixed together by U-shaped clips. Expansion joint pads are provided above and below the central hole of the waterstop, closely attached to the inner side of the templates. Symmetrical through holes are provided at corresponding positions between the upper and lower positioning templates and the expansion joint pads for installing tie bolts. The tie bolts are inserted into the bolts on the side of the waterstop to be poured and welded to the pre-set transversely distributed reinforcing bars on that side. This utility model has a simple structure, is easy to use, and effectively fixes the position of the waterstop using positioning templates, ensuring that the waterstop is not easily displaced during concrete pouring. It also ensures that the central hole of the waterstop is centered in the expansion joint. The operation is simple and quick, saving time and improving project quality, making it highly practical.
[0004] Although the aforementioned patent mentions in its specification that "1. The positioning template effectively fixes the position of the waterstop, ensuring that the waterstop is not easily displaced during the concrete pouring process, and that the central hole of the waterstop can be installed in the center of the expansion joint; 2. The expansion joint pad is used as part of the fixing device to assist in fixing the waterstop. When the positioning template is removed, the expansion joint pad is retained, and the subsequent main body is poured directly, eliminating the need for a later process of setting up the expansion joint pad; 3. The operation process is simple and quick, saving time and improving the quality of the project," the aforementioned patent uses upper and lower positioning templates, steel wires, timber, U-shaped clamps, etc. to fix the waterstop. The timber used for this installation and fixing device needs to be customized, and it needs to be removed after construction, which is time-consuming and labor-intensive. Therefore, in view of the above shortcomings, a centrally embedded steel-edged rubber waterstop installation and fixing structure is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of an embedded steel-edged rubber waterstop installation and fixing structure, comprising an outer wall 1. Multiple structural reinforcing bars 2 are fixedly connected internally to the outer wall 1. The main function of the structural reinforcing bars 2 is to enhance the overall structural strength of the outer wall 1. Two tie rods 3 are fixedly connected internally to the outer wall 1. The side of the structural reinforcing bars 2 away from the steel-edged rubber waterstop 12 is fixedly connected to the outside of the tie rods 3. A tensioning mechanism is slidably connected to the outside of the two tie rods 3. An expansion joint liner 10 is fixedly connected to the right side of the outer wall 1. During the waterstop installation process, the expansion joint liner 10 serves as a basic component, providing a stable installation plane for the positioning template 11. It also provides some protection to the structure at the expansion joint, preventing unnecessary damage or deformation to the expansion joint during construction. This ensures the stability and reliability of the waterstop installation environment, facilitating the smooth progress of subsequent waterstop installation work and the integrity of the entire expansion joint waterproof structure. A positioning template 11 is fixedly connected to the outer right side of the expansion joint liner 10. Before concrete pouring, the positioning template 11 can maintain the shape and position of the waterstop and prevent the waterstop from shifting or deforming during the pouring process.
[0033] Reference Figures 1 to 2 A positioning mechanism is provided on the outer right side of the two tie rods 3. The tensioning mechanism includes two sliding sleeves 4. The outer sides of the two sliding sleeves 4 are respectively located on the outside of the two tie rods 3. A second fixing screw 8 is fixedly connected to the adjacent side of the two sliding sleeves 4. A second fixing nut 9 is threadedly connected to the outer side of the two second fixing screws 8. During installation, the relative position between the second fixing screw 8 and the steel-edged rubber waterstop 12 can be adjusted by rotating the second fixing nut 9, so that the waterstop reaches a suitable position in the height direction and remains taut. Two sliding sleeves 5 are slidably connected to the outer right side of the tie rod 3. A first fixing rod 6 is fixedly connected to the adjacent side of the two sliding sleeves 5. The second fixing rod 8 and the first fixing rod 6 can be made of Φ12 steel bars. Two first fixing nuts 7 are threadedly connected to the outer side of the first fixing rod 6. A steel-edged rubber waterstop 12 is fixedly connected to the outer side of the first fixing rod 6. After the concrete is poured, the steel-edged rubber waterstop 12 can continuously perform its water-stopping function, ensuring the waterproof effect at the expansion joint and ensuring the durability and stability of the entire structure. During the installation of the waterstop, through its cooperation with the sliding sleeves 4 and 5, the steel-edged rubber waterstop 12 is accurately positioned in the height and horizontal direction. After the waterstop is positioned, the second fixing rod 8 and the tie rod 3 are firmly welded together through the sliding sleeves 4, and the first fixing rod 6 and the tie rod 3 are temporarily fixed together through the sliding sleeves 5, thereby stably fixing the waterstop at the expansion joint of the outer wall 1.
[0034] Reference Figures 2 to 3The outer left side of the steel-edged rubber waterstop 12 is fixedly connected to the side of the two second fixing nuts 9, and the outer right side of the steel-edged rubber waterstop 12 is fixedly connected to the side of the two first fixing nuts 7. After the concrete inside the outer wall 1 is poured, the positioning template 11 can be removed by loosening the temporary fixing of the first fixing screw 6 when demolding. When binding the reinforcing bars on the other side of the expansion joint, it is welded and fixed to the structural distribution bars on that side, while ensuring that the steel-edged rubber waterstop 12 is straight.
[0035] Reference Figures 1 to 3 The positioning mechanism includes two adjusting nuts 13, each threadedly connected to the outside of two tie rods 3. Arc-shaped blocks 14 are slidably connected to the outside of each tie rod 3. The left side of the adjusting nut 13 contacts the right side of the arc-shaped block 14. Two fixing rings 15 are fixedly connected to the left side of each arc-shaped block 14. When the adjusting nut 13 rotates, the arc-shaped blocks 14 move with the pushing or pulling action of the adjusting nut 13. This displacement is transmitted to the positioning template 11 through the fixing rings 15, enabling fine-tuning of the positioning template 11's position to adapt to different needs during waterstop installation, ensuring the accuracy of waterstop installation and the stability of the structure. The left side of the fixing rings 15 contacts the right side of the positioning template 11.
[0036] Reference Figures 2 to 3 Holes are drilled on the steel edge of the waterstop according to the horizontal design spacing of the tie rods 3 to install the second fixing rod 8 and the first fixing rod 6. The second fixing rod 8 and the first fixing rod 6 are inserted into the holes of the steel edge rubber waterstop 12. Matching nuts are used to temporarily fix the steel edge rubber waterstop 12 at the top and bottom of the steel edge. The tie rods 3 and the sliding sleeve 2 5 are adjusted up and down to position the steel edge rubber waterstop 12 in the height direction. Then the second fixing rod 8 and the first fixing rod 6 are moved left and right to position in the horizontal direction. After the positioning is accurate, the second fixing rod 8 is welded firmly to the tie rod 3, and the first fixing rod 6 is temporarily fixed firmly to the tie rod 3.
[0037] Working principle: First, install the expansion joint pad 10, positioning template 11, and tie rods 3 according to the template design scheme to initially position the steel-edged rubber waterstop 12. The tie rods 3 should be firmly welded to the structural reinforcing bars 2. Drill holes in the steel-edged rubber waterstop 12 according to the horizontal design spacing of the tie rods 3 to install the second fixing rod 8 and the first fixing rod 6. Insert the second fixing rod 8 and the first fixing rod 6 into the holes of the steel-edged rubber waterstop 12, and temporarily fix the steel-edged rubber waterstop 12 with matching nuts at the top and bottom of the steel edge. The second fixing screw 8 and the first fixing screw 6 can be made of Φ12 steel bars. The second fixing nut 9 and the first fixing nut 7 are adjusted vertically to position the steel-edged rubber waterstop 12 in the height direction. Then, the second fixing screw 8 and the first fixing screw 6 are moved horizontally to position them. After accurate positioning, the second fixing screw 8 is welded firmly to the tie rod 3 using the sliding sleeve 4, and the first fixing screw 6 is temporarily fixed to the tie rod 3 using the sliding sleeve 5. When fixing the second fixing screw 8 and the first fixing screw 6, the steel-edged rubber waterstop 12 should be kept taut, without any loosening or twisting. Finally, after the structural concrete is poured, the formwork can be removed by loosening the temporary fixation of the first fixing screw 6. When tying the reinforcing bars on the other side of the expansion joint, the formwork should be welded and fixed to the structural distribution bars on that side, while ensuring that the steel-edged rubber waterstop 12 is straight.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
