Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically to a waterproof sleeve for exterior walls that does not require sealing. Background Technology

[0002] During basement or subway structure construction, rigid waterproof sleeves are often pre-embedded for pipes penetrating external walls. The conventional practice is to purchase steel pipes and plates, prefabricate and weld them, and then fix them to the reinforcing steel before the civil engineering unit installs the external wall structure formwork. After the concrete is poured and waterproofing is completed, the installers locate the pre-embedded steel sleeves and temporarily seal them using hemp fiber and sealant. However, in actual construction, temporary sealing work is often inefficient if quality is prioritized, and the high cost of sealing materials increases labor and material costs. If only simple sealing is used, rainwater can easily leak from the sleeves after outdoor backfilling, causing indoor water accumulation. Furthermore, repeated manual repairs are required. If the installation of the permanent pipelines is delayed, the sealing and cleaning costs can become considerable.

[0003] The aforementioned technologies involve multiple steps in the fabrication, installation, and sealing of the casing; they require significant labor and sealing materials, resulting in high labor and material costs; and they are prone to leakage during rain and water accumulation, leading to high repair and cleaning costs. Therefore, they present problems such as cumbersome procedures, excessively high sealing and maintenance costs, and a high risk of leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof sleeve for exterior walls that does not require sealing, in order to solve the problems of complicated procedures, high sealing and maintenance costs, and high risk of leakage.

[0005] To achieve the above objectives, the present invention provides a non-sealing waterproof sleeve for exterior walls, employing the following technical solution:

[0006] A type of waterproof sleeve for exterior walls that does not require sealing, including

[0007] The sleeve body has a wing ring arranged circumferentially on its outer wall, and one end of the sleeve body is provided with an internal threaded connector.

[0008] An external threaded plug is threaded to the internal threaded connector, and the end of the external threaded plug is provided with a hexagonal bolt for tool to twist;

[0009] A limiting clip is provided on the inner wall of the sleeve body to constrain the depth to which the external thread plug is screwed into the sleeve body.

[0010] As an optimized version of the waterproof sleeve for exterior walls that does not require sealing, the length of the internal threaded joint is not less than 50mm.

[0011] As an optimization of the non-sealing exterior wall waterproof sleeve, the outer surface of the sleeve body is coated with anti-corrosion paint.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) Dual optimization of process and cost: Through the collaborative design of pre-installed external threaded pipe plug limiter, a one-time seal is achieved during pre-embedding, completely eliminating the secondary sealing process (such as hemp filling), and improving construction efficiency by more than 60%; by installing external threaded pipe plug, the material for temporary sealing of the sleeve is saved in the later stage, reducing material waste and garbage generation, and is environmentally friendly and hygienic; and the thread engagement between the internal threaded joint and the external threaded pipe plug forms a mechanical sealing barrier, fundamentally improving the reliability of waterproofing.

[0014] (2) Convenient disassembly and assembly: The sealing process can be quickly disassembled by operating the hexagonal bolt head with a wrench. The disassembly and assembly takes about 2 minutes, while the traditional method of cleaning up excess sealing material takes 30 minutes, which significantly reduces the time cost of sealing and improves construction efficiency.

However, the embodiments of this utility model are not limited thereto.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0022] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail below.

[0023] This application provides a waterproof sleeve for exterior walls that does not require sealing, using the following technical solution:

[0024] Reference Figure 1 and Figure 2The waterproof sleeve for exterior walls without sealing includes a sleeve body 1, an external threaded plug 2, and a limiting clamp 3. A wing ring 4 is welded circumferentially to the outer wall of the sleeve body 1. The wall thickness and dimensions of the sleeve body 1 and the wing ring 4 refer to the national standard drawing "02S404 Waterproof Sleeve". During pre-embedding, the wing ring 4 is welded to the main reinforcing bars of the building via additional reinforcement, firmly anchoring the sleeve in the concrete wall to prevent displacement during pouring and to withstand axial or radial loads generated by pipe installation and soil backfilling, thus avoiding sleeve deformation. Simultaneously, the outer diameter of the wing ring 4 is larger than the sleeve's aperture, forming a ring barrier that forces water flow to bypass the outer edge of the wing ring 4, significantly extending the penetration path and reducing the risk of leakage. One end of the sleeve body 1 has an integrally formed internal threaded connector 5, which is a round pipe with internal threads. During construction and installation, the internal threaded connector 5 faces the side of the waterproof sleeve facing indoors. The external threaded plug 2 is a cylinder with external threads. The external threads of the external threaded plug 2 match the internal threads of the internal threaded connector 5, and the external threaded plug 2 is threadedly connected to the internal threaded connector 5. A hexagonal bolt 6 is integrally formed and welded to the end face of the external threaded plug 2 away from the sleeve body 1, which can be turned by a wrench or other tools to facilitate the turning of the external threaded plug 2, making the external threaded plug 2 detachably connected to the sleeve body 1. The limiting clip 3 is integrally formed on the inner wall of the sleeve body 1. The limiting clip 3 is a protrusion extending radially into the sleeve body 1. The limiting clip 3 is located at the thread stop of the internal threaded connector 5. When the external threaded plug 2 is screwed into the internal threaded connector 5, the limiting clip 3 can abut against the external threaded plug 2 at the end of the stroke of the internal threaded connector 5, restricting the screwing depth of the external threaded plug 2, avoiding excessive screwing in, avoiding disassembly difficulties, and improving the convenience of the overall device. During the later stages of formal pipeline construction, the limiting clip 3 can also assist in centering the formal pipeline, preventing uneven sealing and omissions caused by the formal pipeline not being installed in the center, thus helping to improve the anti-seepage effect and aesthetics of the formal pipeline construction and installation.

[0025] In the preferred embodiment of this application, the length of the internal threaded connector 5 is not less than 50mm. On the one hand, this ensures that the thread engagement depth of the external threaded pipe plug 2 is sufficient to withstand the pressure of the backfill soil and water pressure without leakage, which helps to improve the sealing performance of the casing body 1. On the other hand, sufficient space is left for the external hexagonal bolt 6 to ensure that the hexagonal bolt 6 can be screwed into the internal threaded connector 5, avoiding interference with other construction operations.

[0026] In a preferred embodiment of this application, the outer surface of the casing body 1 is coated with an anti-corrosion paint, which may be at least one of epoxy resin paint, polyurethane paint, or fluorocarbon paint. The anti-corrosion paint reduces the erosion of the casing body 1 by alkaline environments such as concrete or soil, extends the service life of the casing body 1, and improves the durable anti-permeability effect of the casing body 1.

[0027] The construction process and experimental principle of this application embodiment are as follows: The main body 1 of the sleeve is embedded in the hole at the pre-embedded position. After wrapping the external threaded pipe plug 2 with PTFE tape, it is screwed into the internal threaded connector 5 of the main body 1 of the sleeve. The plug is then tightened with a hex wrench until it abuts against the limiting clip 3, thus completing the assembly of the seal-free external wall waterproof sleeve. The internal threaded connector 5 and the external threaded pipe plug 2 form a one-time seal, eliminating the need for secondary sealing and saving a second step. This not only improves the anti-leakage effect but also saves on procedures and increases construction efficiency. At the same time, it saves on the use of temporary sealing materials, reduces material waste and garbage generation, and lowers sealing and maintenance costs.

[0028] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
