Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a water-stop rod for concrete pouring. Background Technology

[0002] Existing concrete water-stop tie rods typically employ a one-piece molding structure. While this meets basic water-stopping requirements, the tie rods cannot be disassembled after pouring. This results in a large number of exposed rods being cut and removed after pouring, leading to material waste, increased construction costs, and reduced construction efficiency due to the stringent requirements for cutting the tie rods to ensure concrete quality. To address this issue, some improved solutions employ a three-section water-stop tie rod (inner rod, outer rod, and cap) to enhance detachability. However, the existing three-section structure still has the following drawbacks: the cap is difficult to disassemble. After pouring, the cap remains embedded in the walls on both sides of the concrete, requiring additional tools to remove after demolding. This makes it impossible to use locally sourced materials and is inconvenient to operate. Therefore, there is an urgent need for a concrete water-stop rod with partially detachable and reusable components that allows for convenient removal of the cap from locally sourced materials. Utility Model Content

[0003] The purpose of this utility model is to provide a water-stop rod for concrete pouring, in which some parts can be disassembled and reused, reducing the waste of raw materials and saving construction costs; at the same time, it can also use local materials to assist in the disassembly of the cap, improve the convenience of operation, reduce the use of external tools, and save construction costs.

[0004] The present invention adopts the following technical solution:

[0005] A water-stop rod for concrete pouring includes an inner rod with a water-stop ring. Both ends of the inner rod are threadedly connected to caps. An outer rod is threadedly connected to the end of the caps away from the inner rod. A U-shaped clip is movably mounted on the outer rod, and a nut is provided on the side of the U-shaped clip away from the caps. A non-circular adjustment hole is provided at the end of the cap connected to the outer rod, the diameter of which is larger than the diameter of the outer rod. An adjustment block matching the adjustment hole is provided on the outer rod.

[0006] Preferably, the adjusting block is disposed at the end of the outer rod.

[0007] Preferably, the adjusting block is detachably connected to the outer rod.

[0008] Preferably, the adjusting block is threadedly connected to the outer rod.

[0009] Preferably, the adjusting block is located at the end of the nut away from the mountain-shaped clip, and the adjusting block has a through hole for the outer rod to pass through.

[0010] Preferably, both the adjusting block and the adjusting hole are polygonal structures.

[0011] Preferably, the mountain-shaped card is provided with a positioning screw, and the outer rod is provided with a screw hole.

[0012] Preferably, the screw hole is located at one end of the outer rod near the cap base.

[0013] Preferably, the hat stand is a smooth frustum shape.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: By connecting the inner rod and outer rod with a cap-shaped thread, the outer rod and cap-shaped thread can be disassembled and reused after the concrete is poured, leaving only the inner rod inside the poured concrete. This effectively avoids waste of materials and saves construction costs. Furthermore, by setting an adjustment hole at the end of the cap-shaped thread and an adjustment block on the outer rod, the outer rod can be disassembled after construction. The adjustment block can be inserted directly into the adjustment hole, and then rotated to separate the cap-shaped thread from the inner rod, allowing for easy removal of the cap-shaped thread without the need for additional tools. This makes the operation convenient and highly practical. Attached Figure Description

[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0019] like Figures 1 to 3As shown, the present invention discloses a water-stopping rod for concrete pouring, comprising an inner rod 1, a water-stopping ring 2 on the inner rod 1, and caps 3 threadedly connected to both ends of the inner rod 1. The caps 3 are frustoconical in shape, with the inner rod 1 positioned at the end of the caps 3 with the smaller diameter. An outer rod 4 is threadedly connected to the end of the caps 3 away from the inner rod 1. A mountain-shaped clip 5 is movably mounted on the outer rod 4, and a nut 6 is mounted on the side of the mountain-shaped clip 5 away from the caps 3. A non-circular adjustment hole 7 is provided at the end of the caps 3 connected to the outer rod 4. The adjustment hole 7 is coaxially arranged with the threaded hole on the caps 3 for the outer rod 4 to be connected. The diameter of the adjustment hole 7 is larger than the diameter of the outer rod 4 to avoid affecting the threaded connection between the outer rod 4 and the caps 3. An adjustment block 8 matching the adjustment hole 7 is provided on the outer rod 4. After the concrete is poured, since the outer rod 4 and the cap 3 are connected by threads, the cap 3 is precast inside the concrete. The outer rod 4 can be disassembled by rotating it. Then, the adjusting block 8 on the outer rod 4 is inserted into the adjusting hole 7 and the outer rod 4 is rotated to rotate the cap 3. The cap 3 will disengage from the inner rod 1, and the cap 3 can be taken out. The outer wall of the cap 3 is usually coated with a release agent during the concrete pouring process to facilitate the removal of the cap 3.

[0020] Example 1

[0021] like Figure 1 As shown, in this embodiment, the adjusting block 8 is located at the end of the outer rod 4. Preferably, the adjusting block 8 and the outer rod 4 are detachably connected, facilitating the removal and placement of the nut 6 and the U-shaped clip 5. The adjusting block 8 has a protruding screw, and the outer rod 4 has a recessed threaded hole. The adjusting block 8 and the outer rod 4 are threadedly connected, improving the ease of disassembly and installation of the adjusting block 8 and the outer rod 4, and also making them easier to manufacture. In this embodiment, the adjusting block 8 can be installed on one end of the outer rod 4 as needed, reducing manufacturing costs.

[0022] Example 2

[0023] like Figure 2 As shown, in this embodiment, the adjusting block 8 is located at the end of the nut 6 away from the mountain-shaped clip 5, and the adjusting block 8 has a through hole for the outer rod 4 to pass through. In use, rotating the nut 6 moves the adjusting block 8 to the end of the outer rod 4, and inserting the adjusting block 8 into the adjusting hole 7 allows for the disassembly of the cap stand 3. In the prior art, because the thread connecting the outer rod 4 and the nut 6 is different from the thread connecting the outer rod 4 and the cap stand 3, when the outer rod 4 rotates, due to the limiting connection between the adjusting block 8 and the adjusting hole 7, the end of the outer rod 4 will gradually move and abut against the inner wall of the adjusting hole 7. At this time, as the outer rod 4 rotates, the outer rod 4 will no longer move, and thus the adjusting block 8 will drive the cap stand 3 to move, completing the disassembly of the cap stand 3.

[0024] In both embodiments described above, both the adjusting block 8 and the adjusting hole 7 are polygonal structures, preferably hexagonal, to achieve a limiting connection between the adjusting block 8 and the adjusting hole 7. Furthermore, the mountain-shaped clip 5 is provided with a positioning screw 9, and the outer rod 4 is provided with a screw hole 10. By using the positioning screw 9 passing through the screw hole 10, the mountain-shaped clip 5 can be positioned, facilitating the disassembly of the cap stand 3 by using the mountain-shaped clip 5 as a gripping part, thus improving operational convenience. Preferably, the screw hole 10 is located at the end of the outer rod 4 near the cap stand 3. This location is usually near the template and is not threaded, which does not affect the adjustment of the nut 6, while also increasing the distance from the adjusting block 8 to increase torque and improve ease of use. The screw on the mountain-shaped clip 5 does not need to be too long; it only needs to be able to rotate into the screw hole 10 to reduce the adverse effects of the screw during operation.

[0025] In use, the inner rod 1 is located inside the concrete formwork on both sides, while the outer rod 4 is located outside the formwork. The mountain-shaped clip 5 is engaged with and fixed to the rods on the outside of the formwork. After the concrete is poured, the outer rod 4 is rotated to remove it, and the formwork is taken off. The cap platform 3 will be located on the walls on both sides of the concrete. Then, the position of the mountain-shaped clip 5 is adjusted and positioned using the positioning screw 9. Finally, the adjusting block 8 is inserted into the adjusting hole 7, and the outer rod 4 is rotated by the mountain-shaped clip 5. The cap platform 3 will disengage from the inner rod 1 and come off the concrete side wall, thus completing the disassembly of the cap platform 3.
