Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically a quick-release water-stop screw. Background Technology

[0002] In traditional construction, wall formwork reinforcement processes present practical problems in terms of efficiency and management. Taking traditional water-stop tie rods as an example, their structural design exhibits considerable complexity during formwork removal. Whether it's a three-section, five-section, or through-thread type water-stop tie rod, formwork removal requires a fixed sequence: workers must first unscrew the nuts, then remove the mountain-shaped components, followed by disassembling the main and secondary back edges, and finally pull out the outer rod. This process involves multiple steps, and improper operation sequence may damage components or affect the quality of wall formation.

[0003] Furthermore, the management of traditional water-stop bolt components increases the construction burden. Nuts and U-shaped parts are small in size and numerous, making them prone to being scattered and lost during frequent disassembly and assembly. This is especially problematic in multi-story buildings or large-scale construction scenarios, where lost components increase material waste costs and delay the construction period. Simultaneously, the formwork removal process relies on manual operation, requiring construction workers to repeatedly bend over and climb to disassemble components, resulting in high labor intensity and safety hazards. Prolonged work can lead to physical exhaustion and affect construction efficiency. Utility Model Content

[0030] In this embodiment, the waterstop 2 is disc-shaped. In actual production operations, the specific shape and size of the waterstop 2 can be selected according to requirements.

[0031] As a preferred option, such as Figure 1 As shown. The two ends of the water-stopping intermediate rod 1 are detachably connected to one end of the cone 3 via a mutually compatible first threaded assembly. Specifically, as... Figure 3 and Figure 4 As shown, the first threaded assembly includes a first external thread 8 and a first internal thread 9. The two ends of the water-stopping intermediate rod 1 are provided with the first external thread 8. The cone 3 is hollow inside and the inner wall of the cone 3 is provided with the first internal thread 9 that matches the first external thread 8. The water-stopping intermediate rod 1 and the cone 3 are screwed together by the first external thread 8 and the first internal thread 9.

[0032] As a better option, such as Figure 1 and Figure 4 As shown, the other end of the cone 3 (the end of the cone 3 away from the water-stopping intermediate rod 1) is provided with an installation cylinder 11. The central axis of the installation cylinder 11 and the cone 3 coincides and the installation cylinder 11 and the cone 3 are integrated into one piece. The installation cylinder 11 can increase the contact area between the cone 3 and the quick-release outer rod 4, making the connection more stable.

[0033] More preferably, the section of the quick-release outer rod 4 near the cone 3 is a second threaded section, which is detachably inserted into the interior of the mounting cylinder 11 via a mutually compatible second thread set. Specifically, the second thread set includes a second external thread 10 and a second internal thread 12; the surface of the second threaded section is provided with the second external thread 10, and the inner wall of the mounting cylinder 11 is provided with a second internal thread 12 that is compatible with the second external thread 10.

[0034] Preferably, the mountain-shaped part 5 has a mounting hole in the middle that is adapted to the first threaded section, and the mountain-shaped part 5 is movably fitted onto the surface of the first threaded section through the mounting hole.

[0035] As a better option, such as Figure 1As shown, the first threaded section between the mountain-shaped part 5 and the quick-release end 7 is detachably fitted with a limiting component via a mutually compatible third threaded assembly. Specifically, as... Figure 2 and Figure 5 As shown, the third thread group includes a third external thread 13 and a third internal thread 14, and the surface of the first thread segment is provided with the third external thread 13; in this embodiment, the limiting member is specifically a limiting nut 6, the limiting nut 6 is hollow inside and the inner wall of the limiting nut 6 is provided with a third internal thread 14 that is adapted to the third external thread 13.

[0036] Preferably, the quick-release end 7 has a hexagonal longitudinal section, the quick-release outer rod 4 has a diameter between 10mm and 18mm, and the length of the quick-release outer rod 4 is between 170mm and 350mm.

[0037] In this embodiment, the specific selection of the thread on the surface of the quick-release outer rod 4 can be based on actual needs, choosing trapezoidal thread T1-T6, standard thread M10-M18, or semi-circular thread.

[0038] More preferably, in this embodiment, the shape of the quick-release end 7 can be selected to match the shape of the rotating groove of the electric wrench, such as a regular hexagon, a regular triangle, or a regular square.

[0039] The operation method of this utility model is as follows:

[0040] Installation: Screw the cone 3 onto both ends of the water-stop intermediate rod 1. Insert the second threaded section of the quick-release outer rod 4 into the mounting sleeve 11 of the cone 3 and screw them together to complete the initial assembly. Then, pass the quick-release end 7 of one end of the initially assembled water-stop screw through the template hole on one side and fix it simply. Then assemble the template at the other end so that the water-stop screw passes through the two templates. After that, take two mountain-shaped parts 5 and limit nuts 6 respectively. Put the mountain-shaped parts 5 and limit nuts 6 onto the surface of the first threaded section in sequence. Rotate the limit nuts 6 so that the mountain-shaped parts 5 and the template come into contact and fit together. Then carry out intermediate pouring and other work.

[0041] Disassembly: When disassembly is required, since the quick-release ends 7 at both ends of the water-stop screw are exposed, align the groove at the front end of the electric wrench with the quick-release end 7 and insert the quick-release end 7 into the groove; since the quick-release end 7 and the quick-release outer rod 4 are integrated, when the electric wrench is operated, the groove in the center rotates, thereby driving the quick-release end 7 and the quick-release outer rod 4 to rotate, separating the two from the mounting cylinder 11 of the cone 3, and completing the disassembly work;

[0042] Storage: During the above disassembly process, the limiting nut 6 and the mountain-shaped part 5 are always on the surface of the quick-release outer rod 4. After disassembly, the three are stored together, which reduces the possibility of loss of the mountain-shaped part 5 and the limiting nut 6 due to their small size.

[0043] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
