Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense engineering, in particular to a hot-dip galvanized pipe threading structure. Background Art

[0002] The through-the-wall pipe structure of civil air defense projects must be able to prevent shock waves from damaging the interior of the protected space. Civil air defense projects often have various pipelines that pass through the walls of buildings from outside to enter the protected space. According to civil air defense project specifications, the through-the-wall pipe structure of civil air defense projects must be able to prevent shock waves from damaging the interior of the protected space.

[0003] In existing technology, cable wall penetration structures typically include a hot-dip galvanized pipe pre-buried in the wall, the cable passing through the hot-dip galvanized pipe, a resistance plate installed at the end of the hot-dip galvanized pipe, and oil-lined fiber filling the hot-dip galvanized pipe. On-site installation of the wall penetration structure typically requires fasteners (such as bolts and nuts) to pass through the resistance plate. The bolts are then welded to the hot-dip galvanized pipe, allowing the resistance plate to be installed at the end of the hot-dip galvanized pipe. However, this installation method is relatively complex, requiring the cooperation of welders, and the wall penetration structure is complex. Utility Model Content

[0018] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The first, second, third and fourth fasteners mentioned in the present invention may all be screws, but the present invention is not limited thereto and they are not marked in the drawings of the present invention.

[0022] The hot-dip galvanized pipe threading structure of the present invention includes: a hot-dip galvanized steel pipe 200 pre-buried in a concrete wall 100, and both ends of the hot-dip galvanized steel pipe 200 extend out of the concrete wall 100 for cables to pass through, the hot-dip galvanized steel pipe 200 is filled with a sealing layer 300, the sealing layer 300 wraps around the cable in the hot-dip galvanized steel pipe 200, and plugs 600 are installed at both ends of the hot-dip galvanized steel pipe 200.

[0023] This utility model provides a hot-dip galvanized pipe threading structure that installs a plug 600 at the end of a hot-dip galvanized steel pipe 200, replacing the traditional resistance plate. Compared to traditional wall-penetrating pipe structures, the hot-dip galvanized pipe threading structure in this utility model is simple, improves construction efficiency, and does not require the cooperation of professional welders.

[0024] In the present invention, the filling layer is made of any one or more of epoxy resin, polyurethane foam, expanded polyethylene, glass fiber felt, flexible sealing tape, sealing foam gun glue, sealing paste, rock wool, glass wool, and oil linseed.

[0025] In actual implementation, those skilled in the art may select any one or more of the above-mentioned epoxy resin, polyurethane foam, expanded polyethylene, glass fiber felt, flexible sealing tape, sealing foam gun glue, sealing paste, rock wool, glass wool, and oil hemp silk according to actual needs. Here, there is no restriction on the specific material combination of the filling layer.

[0026] The present invention further includes a sealing rib 400 fixed to the outer periphery of the hot-dip galvanized steel pipe 200 , and the sealing rib 400 is located in the concrete wall 100 .

[0027] Specifically, the sealing ribs 400 can resist external loads and impact forces of the hot-dip galvanized pipe threading structure, thereby ensuring the overall stability and durability of the structure.

[0028] In the present invention, the thickness of the sealing rib 400 is ≥3 mm.

[0029] Specifically, the thickness of the sealing rib 400 is selected to be greater than 3 mm, primarily to ensure the strength and stability of the structure. More specifically, thicker sealing ribs 400 provide greater strength to resist external loads and impacts, thereby ensuring the overall stability and durability of the structure. Increased thickness helps to more evenly distribute the load applied to the structure, preventing localized excessive pressure concentration, thereby reducing the risk of deformation and damage. Increased thickness also improves the wear and corrosion resistance of the sealing rib 400, thereby extending its service life.

[0030] In the present invention, a plastic tape 500 is wrapped around the plug 600 .

[0031] Specifically, wrapping the adhesive tape around the plug 600 can reduce the impact of the impact on the plug 600 to a certain extent. The adhesive tape can serve as a buffer material to reduce the direct effect of external impact on the plug 600, thereby reducing the risk of damage to the plug 600.

[0032] In the present invention, the distance from the surface of the concrete wall 100 to the end of the hot-dip galvanized steel pipe 200 is greater than 55 mm.

[0033] Specifically, maintaining an appropriate distance between the wall and the hot-dip galvanized steel pipe 200 facilitates the construction and assembly of the hot-dip galvanized pipe threading structure. This avoids the inability to effectively distribute the impact load due to a too small distance. In actual implementation, those skilled in the art can select an appropriate distance, and this is not specifically limited herein.

[0034] In the present invention, each plug 600 is threadedly connected to the hot-dip galvanized steel pipe 200 , and a through hole (not marked) is provided on the top of each plug 600 , and the through hole is coaxially arranged with the hot-dip galvanized steel pipe 200 .

[0035] Specifically, the plug 600 and the hot-dip galvanized steel pipe 200 are threadedly connected, and the hot-dip galvanized pipe threading structure can be assembled without the cooperation of professional welders. The structure is simpler than the traditional structure, and the installation method is also simpler than the traditional method.

[0036] In the present invention, the plug 600 is conical.

[0037] Specifically, the tapered shape of the drop plug 600 can better disperse the forces applied to it, thereby reducing local stress concentrations. This design helps to evenly distribute the load and improve the overall stability of the structure. The tapered design also provides greater strength because the tapered geometry helps improve resistance to external forces.

[0038] It is worth noting that the end of the tapered plug 600 with a smaller diameter is located at the end away from the hot-dip galvanized steel pipe 200 .

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
