[0002] When constructing waterproof walls such as basements, underground pipe galleries, civil air defense projects and pools, in order to ensure the waterproof quality of the walls, three-section waterstop screws are usually used to install and reinforce the wall formwork. After the wall concrete is poured and the formwork is removed, the outer rod of the waterstop screw needs to be removed so that the outer rod can be recycled and the wall can be waterproofed later.

[0003] During construction, workers often use hammers to remove external rods, causing them to bend, deform, and be damaged, making them unable to be fully recycled. In addition, brute force removal will easily lead to leakage risks at the screw holes in the wall, and the removal efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to provide a device for removing the outer rod of a water-stop screw and a construction method thereof, so as to solve the problem in the prior art that workers often use a hammer to remove the outer rod, which causes the outer rod to bend, deform, and be damaged, so that it cannot be fully recycled; in addition, brute force removal can easily cause leakage hazards at the screw eye of the wall, and the removal efficiency is low. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the present invention are described in detail below.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention provides a water-stop screw outer rod removal device, comprising:

[0007] main body;

[0008] An anti-slip structure connected to the outer surface of the main body, wherein a through groove with a circular cross section is arranged in the anti-slip structure, and an axis of the through groove is parallel to the center line of the main body;

[0009] The limiting assembly at least comprises a first limiting member and a second limiting member, wherein the first limiting member and the second limiting member are respectively connected to two sides of the main body, and the axis is located in the middle of the first limiting member and the second limiting member.

[0010] Preferably, the main body comprises:

[0011] Rods;

[0012] The end cap is arranged at the first end of the rod.

[0013] Preferably, the second end surface of the rod is a planar structure, and a thread is arranged on the outer side of the second end.

[0014] Preferably, the length of the anti-slip structure is not less than 50 mm.

[0015] Preferably, the lengths of the first limiting member and the second limiting member are set to be no less than 50 mm, and the first limiting member, the second limiting member and the anti-slip structure have the same lengths.

[0016] Preferably, the length of the rod is 4-8 times the length of the anti-slip structure, and the cross-sectional diameter of the rod is smaller than the cross-sectional diameter of the through groove.

[0017] Preferably, the cross-section of the end cap is a regular hexagonal structure.

[0032] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, the present invention provides a device for removing the outer rod of a water-stop screw, comprising a main body 1, an anti-slip structure 2 and a limiting component 3.

[0034] Among them, the anti-slip structure 2 is connected to the outer surface of the main body 1, and a through groove 20 with a circular cross-section is arranged in the anti-slip structure 2. The through groove 20 is used for the outer rod 4 of the water-stop screw to pass through, and the axis of the through groove 20 in this embodiment is parallel to the center line of the main body 1.

[0035] The main body 1 in this embodiment adopts a rod-shaped structure, and the center line of the main body 1 is the central axis of the rod.

[0036] The limiting assembly 3 at least includes a first limiting member 31 and a second limiting member 32, the first limiting member 31 and the second limiting member 32 are respectively connected to the two sides of the main body 1, and there is a limiting space between the first limiting member 31 and the second limiting member 32 for limiting the outer rod of the water stop screw 4. The axis of the through groove 20 is located between the first limiting member 31 and the second limiting member 32.

[0037] This device for removing the outer rod of the water-stop screw is provided with an anti-slip structure 2 and a limiting assembly 3 on the outer surface of the main body 1. When in use, the outer rod of the water-stop screw 4 passes through the limiting space and the through groove 20 between the first limiting member 31 and the second limiting member 32 in sequence. After the outer rod of the water-stop screw 4 is effectively limited by the limiting space and the through groove 20 between the first limiting member 31 and the second limiting member 32, the main body 1 is rotated to quickly rotate the outer rod of the water-stop screw 4, so that the outer rod of the water-stop screw 4 can be quickly and intactly removed from the wall. During the removal process, the first limiting member 31, the second limiting member 32 and the anti-slip structure 2 not only limit the outer rod of the water-stop screw 4, but also protect it from bending, thereby solving the problems of bending and deformation of the outer rod in traditional construction, the high risk of leakage in the wall, and low efficiency.

[0038] As an optional implementation, the main body 1 in this embodiment includes a rod 11 and an end 12 , and the end 12 is arranged at the first end 111 of the rod 11 .

[0039] Preferably, the second end surface 112 of the rod 11 is a planar structure, and a thread is disposed on the outer side of the second end 112 .

[0040] Optionally, the length of the rod 11 is 4-8 times the length of the anti-slip structure 2 , and the cross-sectional diameter of the rod 11 is smaller than the cross-sectional diameter of the through groove 20 .

[0041] Specifically, the main body 1 in this embodiment adopts a long-rod bolt. The rod 11 includes a 300mm long M14 screw rod, and the second end surface 112 of the rod 11 is set as a flat structure, which is convenient for fitting the second end 112 of the rod 11 with the surface of the shear wall 4, and ensuring that the main body 1 is perpendicular to the shear wall 6.

[0042] The cross section of the end 12 is a regular hexagonal structure, so that it is easy to connect with tools such as electric wrenches, and the outer rod of the water-stop screw can be removed more time-saving and labor-saving by using electric tools.

[0043] As an optional implementation, the length of the anti-slip structure 2 is not less than 50 mm. Optionally, the anti-slip structure 2 is made of galvanized pipe fittings.

[0044] In this embodiment, the anti-slip structure 2 adopts a DN10 galvanized pipe fitting with a length of 50 mm. The anti-slip structure 2 can cooperate well with the main body 1 to ensure the smooth removal of the water-stop screw outer rod 4.

[0045] As an optional implementation, the length of the first limit member 31 and the second limit member 32 is set to be no less than 50 mm, and the lengths of the first limit member 31, the second limit member 32 and the anti-slip structure 2 are the same.

[0046] In this embodiment, the first limiting member 31 and the second limiting member 32 are both made of Φ12 steel bars with a length of 50 mm.

[0047] Figure 2 It is a schematic diagram of the structure when this embodiment is used, such as Figure 2 As shown, this embodiment also provides a construction method for the above-mentioned water-stop screw outer rod removal device.

[0048] First, it is necessary to assemble the water-stop screw outer rod removal device, that is, weld the anti-slip structure 2 and the limiting component 3 on the main body 1, and ensure that the center lines of the anti-slip structure 2 and the limiting component 3 are consistent.

[0049] Then the outer rod of the water stop screw is removed. The removal of the outer rod of the water stop screw specifically includes the following steps:

[0050] S1: adjusting the installation position, including: making the main body 1 perpendicular to the surface of the shear wall 6;

[0051] S2: connection and installation, including: placing the outer rod 4 of the water-stop screw in the limit assembly 3 and inserting it into the anti-slip structure 2;

[0052] S3: Dismantling: Use a tool to rotate the main body 1 to remove the water-stop screw outer rod 4 and the water-stop screw vertebral body nut 5 from the shear wall 6.

[0053] By adopting this construction method, the removed water-stop screw outer rod 4 is intact and not deformed, can be fully recycled, and can avoid the hidden danger of leakage at the screw eye. In addition, the construction process is simple and convenient, which greatly improves the construction efficiency.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
