Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a device for removing the outer rod of a water-stop screw. Background Technology

[0002] In construction projects involving waterproof walls in basements, underground utility tunnels, civil defense works, and water tanks, three-section water-stop tie rods are typically used for formwork installation and reinforcement to ensure the quality of waterproofing. After the concrete is poured and the formwork is removed, the outer rods of the water-stop tie rods need to be removed to allow for recycling and subsequent waterproofing work on the wall.

[0003] During construction, workers often use hammers to forcefully remove the outer poles, causing them to bend, deform, and become damaged, making them unusable for recycling. In addition, brute force removal can easily lead to leakage at the bolt holes in the wall, and the removal efficiency is low. Utility Model Content

[0004] The purpose of this utility model is to provide a device for removing the outer rod of a water-stop screw, to solve the problems in the existing technology where workers often use hammers to forcefully remove the outer rod, causing it to bend, deform, and be damaged, preventing its full recycling; in addition, brute force removal can easily lead to leakage at the screw hole in the wall, and the removal efficiency is low. The various technical effects of the preferred technical solution provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a device for removing the outer rod of a water-stop screw, including:

[0007] main body;

[0008] An anti-detachment structure is connected to the outer surface of the main body. The anti-detachment structure has a circular cross-section through groove, and the axis of the through groove is parallel to the center line of the main body.

[0009] The limiting component includes at least a first limiting member and a second limiting member, the first limiting member and the second limiting member being respectively connected to both sides of the main body, and the axis being 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 is located at the first end of the rod.

[0013] Preferably, the second end face of the rod is a planar structure, and the outer side of the second end is provided with threads.

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

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

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

[0018] Preferably, the anti-detachment structure is made of galvanized pipe, and the first limiting member and the second limiting member are made of steel bars.

[0019] This utility model provides a device for removing the outer rod of a water-stop screw, comprising a main body, an anti-detachment structure, and a limiting component. By setting the anti-detachment structure and limiting component on the outer surface of the main body, during use, the outer rod of the water-stop screw passes sequentially through the limiting space and through groove between the first and second limiting members.

During the removal process, the first and second limiting members and the anti-detachment structure not only limit the outer rod but also provide anti-bending protection, solving problems such as bending deformation of the outer rod, easy leakage of the wall, and low efficiency in traditional construction methods.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, this utility model provides a device for removing the outer rod of a water-stop screw, including a main body 1, an anti-detachment structure 2, and a limiting component 3.

[0029] The anti-detachment structure 2 is connected to the outer surface of the main body 1. The anti-detachment structure 2 is provided with a circular cross-section through groove 20. The through groove 20 is used for the outer rod 4 of the water-stop screw to pass through. In this embodiment, the axis of the through groove 20 is parallel to the center line of the main body 1.

[0030] In this embodiment, the main body 1 adopts a rod-shaped structure, and the center line of the main body 1 is the central axis of the rod.

[0031] The limiting component 3 includes at least 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 both sides of the main body 1. The space between the first limiting member 31 and the second limiting member 32 is used to limit the outer rod 4 of the water-stop screw. The axis of the through groove 20 is located between the first limiting member 31 and the second limiting member 32.

[0032] This device for removing the outer rod of a water-stop screw rod utilizes an anti-detachment structure 2 and a limiting component 3 on the outer surface of the main body 1. During use, the outer rod 4 of the water-stop screw rod passes sequentially through the limiting space and through groove 20 between the first limiting member 31 and the second limiting member 32. After the water-stop screw rod 4 is effectively limited by the limiting space and through groove 20 between the first limiting member 31 and the second limiting member 32, rotating the main body 1 allows for rapid rotation of the outer rod 4, enabling its quick and intact removal from the wall. During the removal process, the first limiting member 31, the second limiting member 32, and the anti-detachment structure 2 not only limit the outer rod 4 but also provide anti-bending protection, solving problems such as bending deformation of the outer rod, easy leakage of the wall, and low efficiency in traditional construction methods.

[0033] As an optional implementation, the main body 1 in this embodiment includes a rod 11 and an end 12, with the end 12 disposed at the first end 111 of the rod 11.

[0034] Preferably, the second end face 112 of the rod 11 is a planar structure, and the outer side of the second end 112 is provided with threads.

[0035] Optionally, the length of the rod 11 is 4-8 times the length of the anti-detachment structure 2, and the cross-sectional diameter of the rod 11 is smaller than the cross-sectional diameter of the through groove 20.

[0036] Specifically, in this embodiment, the main body 1 adopts a long bolt. The rod 11 includes an M14 screw with a length of 300mm. The second end face 112 of the rod 11 is set as a planar structure, which facilitates the second end 112 of the rod 11 to fit against the surface of the shear wall 4, ensuring that the main body 1 is perpendicular to the shear wall 6.

[0037] The cross-section of end 12 is a regular hexagonal structure, which facilitates connection with tools such as electric wrenches, allowing for more time-saving and labor-saving removal of the outer rod of the water-stop screw using electric tools.

[0038] As an optional implementation, the length of the anti-detachment structure 2 is not less than 50 mm. Optionally, the anti-detachment structure 2 is made of galvanized pipe.

[0039] In this embodiment, the anti-detachment structure 2 is a 50mm long DN10 galvanized pipe fitting. The anti-detachment structure 2 can fit well with the main body 1 to ensure the smooth removal of the outer rod 4 of the water-stop screw.

[0040] As an optional implementation, the lengths of the first limiting member 31 and the second limiting member 32 are set to be no less than 50mm, and the lengths of the first limiting member 31, the second limiting member 32, and the anti-detachment structure 2 are the same.

[0041] In this embodiment, both the first limiting member 31 and the second limiting member 32 are made of Φ12 steel bars with a length of 50mm.

[0042] Figure 2 This is a schematic diagram of the structure used in this embodiment, as shown below. Figure 2 As shown in the figure, this embodiment also provides a construction method for the above-mentioned water-stop screw outer rod removal device.

[0043] First, the water-stop screw outer rod removal device needs to be assembled, that is, the anti-detachment structure 2 and the limiting component 3 are welded on the main body 1. It is necessary to ensure that the center lines of the anti-detachment structure 2 and the limiting component 3 are aligned.

[0044] Then, the outer rod of the water-stop screw is removed. The removal of the outer rod of the water-stop screw includes the following steps:

[0045] S1: Adjust the installation position, including: making the main body 1 perpendicular to the surface of the shear wall 6;

[0046] S2: Connection and installation, including: placing the outer rod 4 of the water-stop screw in the limiting component 3 and inserting it into the anti-detachment structure 2;

[0047] S3: Dismantle, use tools to rotate the main body 1, and remove the outer rod 4 of the water-stop screw and the cone nut 5 of the water-stop screw from the shear wall 6.

[0048] Using this construction method, the removed outer rod 4 of the water-stop screw rod remains intact and undeformed, allowing for full recycling and preventing potential leakage at the screw rod eye. Furthermore, the construction process is simple and convenient, greatly improving construction efficiency.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
