Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a three-stage water-stop screw plastic plug removal device. Background Art

[0002] The three-stage water-stop screw is a commonly used product component in construction, such as widely used in the pouring operations of basements, garages, culverts, tunnels, sewage pools, pools, etc. The main functions include preventing water leakage, preventing the intrusion of foreign substances, and protecting the stability of the building structure, playing a role in stabilizing the building structure and protecting it.

[0003] The three-stage water-stop screw structure is as shown in the instruction manual. Figure 1 As shown, it includes an intermediate rod with an attached water stop sheet, and a side rod connected to the end of the intermediate rod through a plastic plug. The use state is as follows Figure 2 As shown, the middle rod is located between the two side templates, and a plastic plug is set on its end, and the outer end of the plastic plug is detachably connected to the side rod located outside the template. The three-section water-stop screw and the template can be assembled through the mountain-shaped piece and the steel pipe, and the positioning of the double-side template can be achieved. Figure 3-4 As shown, after pouring is completed, the mountain-shaped parts, steel pipes, side rods and formwork are removed, and the plastic plugs and the middle rods are further removed, and then the trough body at the plastic plugs is sealed with concrete, and the construction is completed.

[0004] like Figure 5 As shown, the plastic plug currently in use is a double-layer threaded tube structure, and reinforcing plates are arranged at radial intervals on it, and a disassembly clamping cavity is formed between adjacent reinforcing plates. When it is dismantled at a later time, a clamp is usually used to clamp the clamping tube on the inner side of the plastic plug, and an external force is applied to drive the plastic plug to rotate, so that the plastic plug and the middle rod can be disassembled.

[0005] Since the plastic plug is a plastic structure and is pressed when pouring concrete, it is very easy to cause the inner cylinder to break when it is rotated and disassembled by tools such as pliers in the later stage (such as Figure 6 As shown), the main body strength of the plastic plug is further reduced, which in turn causes the plastic plug to be unable to be removed and remain in the concrete wall, affecting the subsequent plugging construction. Summary of the invention

[0006] In response to the above-mentioned problems, the present application aims to provide a three-stage water-stop screw plastic plug removal device, in which the sleeve is synchronously assembled and connected to multiple clamping cavities. When the plastic plug is disassembled, the external force of disassembly is dispersed on multiple reinforcing plates, thereby avoiding the current problem of excessive stress concentration during disassembly, which may cause the plastic plug to rupture, and realizing a quick and complete disassembly operation of the plastic plug.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a three-stage waterstop screw plastic plug removal device, the three-stage waterstop screw has an intermediate rod with an attached waterstop plate, and a side rod connected to the end of the intermediate rod through a plastic plug, the plastic plug is a double-layer threaded tube structure, and reinforcing plates are arranged at radial intervals thereon, and disassembly clamping cavities are formed between adjacent reinforcing plates, characterized in that: the removal device is synchronously assembled and connected with a plurality of the clamping cavities, and has a positioning mechanism for positioning with the clamping cavity.

[0008] Preferably, the removal device comprises a sleeve mounted on the tool, and an embedding body which is cut at one end of the sleeve and is embedded in the plurality of clamping cavities.

[0009] Preferably, the positioning mechanism is a pointed body portion which is provided on the side wall of each of the embedded bodies and can be embedded into the reinforcing plate by external force.

[0010] Preferably, the positioning mechanism is a traction body which can be embedded in the side wall of the plastic plug and is provided on the inner wall of one end of each of the embedded bodies.

[0011] The beneficial effect of the present application is that the present application is provided with a dismantling device, and its sleeve is synchronously assembled and connected with multiple clamping cavities. When the plastic plug is dismantled, the dismantling external force is dispersed on multiple reinforcing plates, avoiding the current problem of excessive stress concentration during dismantling, which causes the plastic plug to rupture, and realizing a quick and complete dismantling operation of the plastic plug.

[0012] The positioning mechanism of the removal device enables the sleeve to be relatively positioned with the plastic plug as a whole through the clamping cavity. Therefore, during the subsequent removal, the removal device not only applies a rotational external force to the plastic plug, but also further applies an axial removal force, so that the plastic plug can overcome the pressure of the concrete and be removed smoothly.

[0029] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0030] See attached Figures 1 to 15 The three-stage water-stop screw plastic plug removal device shown in the figure has an intermediate rod 1 with a water-stop sheet 3, and a side rod 2 connected to the end of the intermediate rod 1 through a plastic plug 4. The assembly of the entire screw with the template and the positioning of the double-sided template are as follows: Figure 2 shown.

[0031] like Figure 5 As shown, the plastic plug 4 is a double-layer threaded tube structure, and reinforcing plates 41 are arranged at radial intervals thereon, and a disassembly clamping cavity 4a is formed between adjacent reinforcing plates 41. During later disassembly, tools such as pliers are currently used to clamp and rotate the disassembly.

[0032] In order to avoid the current problem of plastic plugs being broken and difficult to remove smoothly during disassembly, the present application provides a disassembly device, which is synchronously assembled and connected with the multiple clamping cavities 4a. Therefore, during disassembly, the disassembly external force is dispersed on the multiple reinforcing plates 41, avoiding the current problem of excessive concentration of stress during disassembly, which may cause the plastic plug to break, thereby achieving a quick and complete disassembly operation of the plastic plug.

[0033] During the above disassembly, the dismantling device applies a rotational force to the plastic plug, and the plastic plug withdraws automatically by utilizing the threaded matching structure between the plastic plug and the intermediate rod 1. However, the outer wall of the plastic plug is pressed against the poured concrete, thereby forming a withdrawal resistance, and further causing the internal thread of the plastic plug to slip, and the plastic plug cannot be disassembled. Therefore, in order to solve this problem, the dismantling device has a positioning mechanism for positioning with the clamping cavity 4a. The positioning mechanism enables the dismantling device to achieve relative positioning with the plastic plug as a whole through the clamping cavity 4a, and then during subsequent dismantling, in addition to applying a rotational external force to the plastic plug, the dismantling device further applies an axial dismantling force, so that the plastic plug can overcome the pressing force of the concrete and be successfully dismantled.

[0034] Specifically, Figure 7-12 As shown, the removal device includes a sleeve 5 mounted on a tool, and the tool is preferably a handheld electric tool that can be mounted with the sleeve 5. An embedding body 51 is cut and opened at one end of the sleeve 5 to be embedded in a plurality of clamping cavities 4a. When removing the plastic plug, the plurality of embedding bodies 51 opened by the sleeve 5 are inserted into the corresponding clamping cavities 4a ( Fig.11 As shown), a handheld electric tool is then assembled on the outer end of the sleeve 5, and then the sleeve 5 is driven to rotate by the electric tool, and multiple embedded bodies 51 of the sleeve 5 contact multiple reinforcing plates 41, driving the plastic plug 4 to rotate, and the external thread of the intermediate rod 1 is used to realize the automatic withdrawal and disassembly of the plastic plug 4.

[0035] In order to achieve the relative positioning of the sleeve 5 and the plastic plug 4, the present application provides the following two embodiments:

[0036] Example 1

[0037] like Figure 13-14 As shown in FIG. 1 , the positioning mechanism is that each of the side walls of the embedded body 51 is provided with a pointed body 52 that can be embedded into the reinforcing plate 41 by external force. Since the plastic plug is made of plastic material, when the sleeve 5 is used for removal, the embedded body 51 is attached to the side wall of the reinforcing plate 41 and exerts a pressing effect, thereby driving the pointed body 52 to penetrate into the reinforcing plate 41. Fig.12 As shown, the sleeve 5 is driven outward by a hand-held electric tool at the same time, and the plastic plug can be pulled out axially to overcome the pressing resistance of the concrete.

[0038] Example 2

[0039] like Fig.15 As shown, the positioning mechanism is that a traction body 53 is provided on the inner wall of one end of each of the embedded bodies 51 and can be embedded in the side wall of the plastic plug 4. The embedded body 51 of this embodiment is suitable for a gap between the inner wall of the plastic plug 4 and the poured concrete. When in use, the embedded body 51 is externally inserted from the clamping cavity 4a. During the insertion process, the end of the traction body 53 close to the axis of the plastic plug squeezes the reinforcing plate 41. After the insertion, the reinforcing plate 41 recovers its deformation, and the side wall of the traction body 53 overlaps with the side wall of the plastic plug by a certain width (such as Fig.15 As shown), in the process of driving the sleeve 5 outward, the traction body 53 exerts a force on the side wall of the plastic plug 4 to overcome the pressing force of the concrete, and the plastic sleeve is successfully removed.

[0040] The principle of the present application is: an embedded body 51 having a clamping cavity 4a in which multiple plastic plugs 4 are embedded is cut and processed at one end of a conventional sleeve 5, and a pointed body portion 52 is reserved and cut on the side wall of the embedded body 51, or a traction body 53 is reserved and cut on the inner wall of the outer end of the embedded body. During the removal operation, the multiple embedded bodies 51 opened by the sleeve 5 are inserted and embedded into the corresponding clamping cavities 4a, and then a hand-held electric tool is assembled on the outer end of the sleeve 5, and then the sleeve 5 is driven to rotate by the electric tool, and the multiple embedded bodies 51 of the sleeve 5 are in contact with multiple reinforcing plates 41, or the traction body 53 is close to the side wall of the plastic plug, and then the hand-held electric tool drives the plastic plug 4 to rotate, and the pointed body portion 52 is rolled into the side wall of the reinforcing plate 41, or the traction body 53 drives its side wall, so that the plastic plug overcomes the pressing resistance of the concrete, and the plastic plug 4 is removed smoothly.

[0041] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
