[0002] Leaks around pipes have attracted widespread attention in the construction industry, and the application of waterproof sleeves has increased the reliability of building exteriors and piping equipment.

[0003] Traditional wall-penetrating waterproof sleeve construction requires making a circular opening in the wall formwork during formwork assembly to insert the sleeve. Often, gaps remain between the formwork opening and the outer wall of the sleeve, causing concrete leakage during pouring. This results in low sleeve embedding efficiency, impacting construction progress and aesthetic quality. Inaccurate sleeve embedding leads to incomplete concrete compaction, posing a significant risk of water seepage. Furthermore, subsequent waterproofing membrane installation necessitates chiseling and rounding around the sleeve, wasting labor and materials. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-8This utility model provides a technical solution: a tool for pre-embedding a waterproof sleeve at its root arc, comprising an embedded part 1. The embedded part 1 consists of a tapered steel pipe 11, a U-shaped handle 12, a steel plate 13, a quick-release fixing screw 14, a rubber sealing ring 15, a waterproof wing ring 16, a connecting rod 17, an adjusting nut 18, a positioning nut 19, a sealing ring 20, an elastic sealing structure 21, and a fixing hole 22. There are two steel plates 13, which are symmetrically and parallelly arranged opposite each other. The symmetrical arrangement ensures the balanced force of the embedded part in the concrete wall and prevents displacement. A tapered steel pipe 11 is vertically welded to the middle of each steel plate 13. The larger end of the tapered steel pipe 11 faces the template 6, and the smaller end is adapted to the outer diameter of the through-wall steel sleeve 3. This tapered design facilitates the insertion of the through-wall pipe and can provide preliminary positioning. At the same time, the larger end... The orientation of the template facilitates the overall installation of the tools. The connecting rod 17 passes through the through holes at the four corners of the two steel plates 13 at both ends. The spacing between the steel plates is locked by adjusting the nuts 18 and positioning the nuts 19 through the threaded connection. The threaded adjustment mechanism can precisely control the spacing between the steel plates, thereby achieving precise adjustment of the position and length of the through-wall pipe to meet different construction requirements. The sealing component is embedded at the connection between the steel plate 13 and the tapered steel pipe 11, covering the outer wall of the through-wall steel sleeve 3. The sealing component is set at the key connection to effectively prevent leakage that may occur during concrete pouring and ensure waterproof effect. The U-shaped handle 12 is symmetrically welded to the middle of the adjacent side edges of the two steel plates 13. The symmetrical U-shaped handle provides a stable grip point, which is convenient for construction personnel to move, position and disassemble the steel plates, reducing labor intensity.

[0030] In this invention, preferably, the tapered steel pipe 11 is radially locked into the mounting hole of the steel plate 13 by quick-release fixing screws 14. The design of the quick-release fixing screws facilitates quick installation and removal of the tapered steel pipe, improving the reusability of the tool. At least three quick-release fixing screws 14 are evenly distributed around the circumference of the tapered steel pipe 11. The evenly distributed fixing screws ensure the firmness and stability of the connection between the tapered steel pipe and the steel plate, preventing rotation or loosening. The sealing assembly includes a rubber sealing ring 15 and an elastic sealing structure 21, adopting a double sealing structure (rubber sealing ring and elastic sealing structure). The structure greatly enhances the reliability of the seal, adapting to pressure changes during concrete pouring and effectively preventing leakage. The rubber sealing ring 15 is nested inside the small end of the tapered steel pipe 11, and the rubber sealing ring nested inside the inner wall directly contacts the through-wall pipe, forming the first line of defense to prevent water from seeping in through the gap between the pipe wall and the inner wall of the tapered pipe. The elastic sealing structure 21 is fitted onto the outer wall of the small end of the tapered steel pipe 11. The elastic sealing structure on the outer wall can fit tightly against the outer wall of the through-wall pipe and deform under concrete pressure, further compacting and sealing to form the second line of defense. The connecting rod 17 has two ends. The threaded section extends beyond the outer side of the steel plate 13. The adjusting nut 18 is located on the outer side of the steel plate 13, and the positioning nut 19 is located on the inner side of the steel plate 13. This arrangement of threads and nuts makes adjustment convenient to be performed on the outer side, while the positioning nut provides stable support on the inner side. By turning the adjusting nut 18, the center position and protrusion length of the through-wall steel sleeve 3 in the shear wall 7 are controlled. Turning the adjusting nut can adjust the position and length of the through-wall pipe in real time and accurately, ensuring the accuracy of the pre-embedding and reducing the workload of subsequent corrections. A tapered steel pipe 11 with a suitable diameter is opened in the middle of the steel plate 13. The circular hole has four fixing holes 22 arranged in a ring around its edge for bolting the sealing assembly. The design of the circular hole and fixing holes ensures the installation position of the tapered steel pipe and provides a reliable fixing point for the sealing assembly, ensuring a long-lasting sealing effect. The U-shaped handle 12 has its straight arm section vertically welded to the surface of the steel plate 13, and the opening end of the U-shaped handle 12 faces the outside of the steel plate 13. The vertical welding of the straight arm enhances the connection strength between the handle and the steel plate. The design of the opening facing outward makes it easy for fingers to insert and grip, making operation more comfortable and effortless. The waterproof wing ring 16 is coaxially welded to the middle of the through-wall steel sleeve 3.The outer diameter of the waterproof wing ring 16 is larger than the inner diameter of the large opening of the tapered steel pipe 11. The coaxially welded waterproof wing ring forms a reliable barrier within the concrete wall. Combined with its design, which is larger than the inner diameter of the tapered pipe, it effectively prevents water from seeping along the outer wall of the through-wall pipe, making it a key part of the waterproof structure. A sealing ring 20 is installed at the gap between the connecting rod 17 and the through hole of the steel plate 13. The sealing ring 20 is pressed between the positioning nut 19 and the inner side of the steel plate. The installation of the sealing ring at the gap between the connecting rod and the through hole of the steel plate, and the use of the positioning nut for tightening, prevents concrete from seeping in from around the connecting rod, ensuring... To ensure the overall sealing of the embedded parts, four connecting rods 17 are used, each penetrating through the four corner holes of two steel plates 13 to form a rectangular frame structure. This rectangular frame structure ensures a stable connection between the two steel plates, providing strong overall integrity and the ability to withstand the lateral pressure during concrete pouring. The protruding ends of the connecting rods 17 are locked to the main formwork joists 4 and secondary formwork joists 5 using fasteners. The fasteners secure the tool to the formwork system, ensuring the embedded parts remain stable during concrete pouring and preventing displacement. Reinforcing bars 2 are installed inside the formwork 6.

[0031] The working principle and usage process of this utility model are as follows: In use, firstly, the waterproof wing ring 16 is coaxially welded to the middle of the through-wall steel sleeve 3; take two steel plates 13, and weld the tapered steel pipe 11 with the large end facing the template 6 vertically to the round hole in the middle of each steel plate 13, ensuring that the inner wall of the small end of the tapered steel pipe 11 is nested with a rubber sealing ring 15, and the outer wall is fitted with an elastic sealing structure 21, and the sealing assembly is fixed by bolts through the fixing holes 22 on the edge of the round hole; insert the four connecting rods 17 sequentially through the through holes at the four corners of the two steel plates 13, and screw in the positioning nut 19 in the section of each connecting rod 17 located on the inner side of the steel plate 13, and screw in the adjusting nut 18 in the outer section; Next, insert the through-wall steel sleeve 3 into the small end of the tapered steel pipe 11, and use at least three quick-release fixing screws 14 to lock the tapered steel pipe 11 and the steel plate 13 radially around the circumference of the tapered steel pipe 11; symmetrically weld U-shaped handles 12 to the middle of the adjacent side edges of the two steel plates 13, ensuring that the open end of the U-shaped handle 12 faces outward; by simultaneously tightening the adjusting nuts 18 on the four connecting rods 17, precisely adjust the distance between the two steel plates 13, thereby controlling the center position and wall protrusion length of the through-wall steel sleeve 3 in the shear wall 7; lock the protruding end of the connecting rod 17 to the main keel 4 and the secondary keel 5 of the template through fasteners, so that the embedded part 1 and the template 6 reinforcement system form an integral whole. Before pouring concrete, confirm that the sealing ring 20 at the gap between the connecting rod 17 and the through hole of the steel plate 13 is pressed tightly against the inner side of the steel plate 13 by the positioning nut 19; after the concrete has solidified, loosen the fastener, loosen the adjusting nut 18, remove the connecting rod 17, loosen the quick-release fixing screw 14, hold the U-shaped handle 12 to separate the two steel plates 13, take out the tapered steel pipe 11 and the sealing assembly, and complete the disassembly and recycling.
