[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0040] Reference Figure 1-5 The waterproof pull tab shown includes:

[0041] The main body section of the pull-tab is 100mm, which serves to support and operate the pull-tab.

[0042] The serrated protrusions 200 are provided in two sets and are fixedly installed on both sides of the pull tab body section 100, making it easier and more stable to operate the pull tab and less prone to slippage.

[0043] There are two pull tab transition sections 300, which are fixedly installed at both ends of the pull tab main body section 100 to serve as a transition and connection, reduce stress concentration, and improve the overall structural strength of the pull tab.

[0044] Two pull tab connecting sections 400 are provided and are fixedly installed at the end of the pull tab transition section 300 away from the pull tab transition section 300. They are used to connect with other components and facilitate quick positioning during assembly.

[0045] The guide seam 500 is set at the connection between the pull tab connecting section 400 and the pull tab transition section 300 to facilitate the breakage of the pull tab connecting section 400;

[0046] Two fastening components 600 are provided and fasten to the outside of the pull tab connecting section 400 and extend to the guide seam 500, providing additional fixation and protection. The size of the fastening components 600 is larger than the template gap and will not get stuck inside the template gap.

[0047] The working principle of this embodiment is as follows:

[0048] When in use, place the installed pull tab connecting section 400 at the pre-milled hole and fix it with a pin. Then install the aluminum mold on the other side. After the concrete is poured and the strength is reached, remove the fastening component 600. Then use a hammer to strike the pull tab connecting section 400 to break it off from the concrete. Finally, repair the gap left after the pull tab connecting section 400 is separated with cement grout.

[0049] The design of the pull tab transition section 300 reduces stress concentration, and the fastening component 600 fixes and protects the pull tab connection section 400. The overall structure has high strength and a long service life.

[0050] By adding serrated protrusions 200, the water flow path is increased, making it difficult for rainwater to enter the room. This solves the problem of waterproofing difficulties in rain-prone areas, making the waterproofing more effective and increasing friction and stability.

[0051] The fastening component 600 prevents the pull tab connecting section 400 from breaking under external force.

[0052] When the serrated protrusions with a 200mm bevel come into contact with the concrete, they form a multi-stage stepped water-blocking structure (such as...). Figure 2 (As shown). When rainwater seeps along the surface of the pull plate, the vertical surface of the saw teeth forces the water flow to change direction, while the horizontal surface B and the concrete form a micro-sealing layer through vibration compaction.

[0053] In some embodiments of this utility model, reference is made to Figure 3 As shown, the guide seam 500 is triangular in shape, and a triangular plate 510 is detachably inserted inside the guide seam 500.

[0054] The design of the guide seam 500 and the break notch 410 allows the pull tab connecting section 400 to be easily and quickly disassembled when needed, making the operation simple. At the same time, the insertion of the triangular plate 510 ensures the strength of the pull tab during use and prevents it from breaking.

[0055] In some embodiments of this utility model, reference is made to Figure 3 As shown, two break-off notches 410 are provided at the connection between the pull tab connecting section 400 and the pull tab transition section 300, and the two break-off notches 410 are connected to the guide seam 500.

[0056] The two break notches 410 are used to facilitate the breakage and separation of the pull tab when needed. The design of the guide slot 500 allows for smoother and more precise control of the breakage position during the breakage process, ensuring that the broken pull tab can be separated smoothly without affecting the integrity of other structures.

[0057] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the fastening assembly 600 includes:

[0058] Two U-shaped plates 610 are provided and are sleeved on the outside of the triangular plate 510 and the pull tab connecting section 400. They can closely fit the inclined surface of the triangular plate 510 and the outer contour of the pull tab connecting section 400, and achieve initial positioning through interference fit, so as to provide structural support and stable connection.

[0059] The fastening groove 620 is provided on one of the U-shaped plates 610 and is designed to be concave to facilitate the fastening operation;

[0060] The snap-fit ​​head 630 is fixedly installed on another U-shaped plate 610 and snaps into the snap-fit ​​groove 620. The mechanical interlocking achieves a tight connection and ensures the overall structural integrity.

[0061] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, a limiting protrusion 640 is fixedly installed inside the U-shaped plate 610, which contacts the inner wall of the broken notch 410.

[0062] Among them, the limiting protrusion 640 can further improve the stability of the pull tab connecting section 400 and the fastening assembly 600, and prevent them from shaking or shifting during use.

[0063] In some embodiments of this utility model, reference is made to Figure 2 As shown, each group of serrated protrusions 200 is provided with multiple protrusions, and the multiple serrated protrusions 200 are arranged horizontally.

[0064] This arrangement maximizes the friction between the hand and the pull tab, improving ease of operation and stability.

[0065] In some embodiments of this utility model, reference is made to Figure 3 As shown, the pull tab connecting section 400 has a through hole 420 that runs from front to back. The inside of the through hole 420 is bonded with an anti-slip pad 430 to prevent the connector from sliding or falling off, thereby improving the flexibility and safety of use.

[0066] The working method of this utility model:

[0067] During installation, the installed pull tab connecting section 400 is placed at the pre-milled hole and fixed with a pin. Then, the aluminum mold on the other side is installed. After the concrete is poured and the strength is reached, the fastening component 600 is removed.

[0068] Then, the triangular plate 510 is removed from the inside of the guide joint 500, and the tie plate connecting section 400 is struck with a hammer to break it off from the concrete. Finally, the gap left after the tie plate connecting section 400 is removed is repaired with cement grout.

[0069] Before use, insert the triangular plate 510 into the inside of the guide seam 500, and wrap the U-shaped plate 610 around the outside of the triangular plate 510 and the pull tab connecting section 400, and splice them together through the fastening groove 620 and the fastening head 630.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
