Description

Technical Field

[0001] This utility model relates to the field of water seepage prevention technology in building construction, specifically a water-proof through-wall pipe structure. Background Technology

[0002] During engineering construction, especially in civil defense projects and other special types of projects, we often encounter situations where it is necessary to install through-wall pipes. This renovation solution is very common in practice, especially when installing various equipment such as exhaust fans, air conditioners, drainage pipes, and electrical conduits. The normal operation of these devices often depends on the proper layout and installation of the through-wall pipes.

[0003] In actual construction, when drilling through-wall holes to install through-wall pipes, it's often difficult to ensure a perfect seal between the hole and the pipe. To facilitate installation, engineers typically design the inner diameter of the through-wall hole to be slightly larger than the outer diameter of the pipe. While this provides convenience, it also creates a problem: large gaps remain between the through-wall hole and the pipe after installation. These gaps not only affect the overall aesthetics but, more seriously, can easily lead to water seepage. Water seepage can damage the wall structure and cause a series of subsequent problems, such as mold growth and electrical safety hazards. Therefore, effectively solving the sealing problem after through-wall pipe installation has become a key technical challenge that engineers need to focus on and address. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a waterproof through-wall pipe structure. This clamp aims to solve the sealing problem after the through-wall pipe is installed, preventing water leakage at the pipe's location.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The through-wall pipe includes: an inner tube, a sleeve, axial sealing ribs, radial sealing ribs, spray holes, and pull rings; the inner tube has threads at both ends, and a sleeve of the same length as the middle area is coaxially installed in the middle of the inner tube; the axial sealing ribs are rings of uniform thickness, with the inner diameter being the same as the outer diameter of the inner tube and the outer diameter being larger than the outer diameter of the sleeve; the axial sealing ribs are respectively installed along the axial direction of the sleeve at both ends and the middle of the sleeve, forming a storage cavity together with the inner tube and the sleeve; the radial sealing ribs are rectangular plates of uniform thickness and length matching the sleeve, with the length matching the sleeve length; multiple radial sealing ribs... The ribs are set at equal angles along the circumference of the sleeve, and the axial sealing ribs, together with the inner tube and the sleeve, form a storage cavity that is further divided into multiple storage chambers. Each storage chamber has a spray hole on the outer wall of the sleeve, which is sealed by a pull ring. In use, the through-wall pipe is placed in the opening in the wall and the pull ring is pulled. The foam adhesive pre-stored in the storage chamber will be sprayed out through the spray hole under pressure. After the foam adhesive has cured, the sealing gaskets are installed at both ends of the through-wall pipe, so that one side of the sealing gasket abuts against the axial sealing rib, and then the fixed end cap is installed so that the other side of the sealing gasket abuts against the fixed end cap.

[0008] Preferably, there are one axial sealing rib, which is respectively set at both ends and the middle of the sleeve along the axial direction of the sleeve, and one radial sealing rib, which is respectively set at an angle of ° along the circumference of the sleeve.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model discloses a waterproof through-wall pipe structure, including a through-wall pipe 1, a wall 2, a fixed end cap 3, and a sealing gasket 4.

[0026] The through-wall pipe 1 includes: an inner pipe 101, a sleeve 102, an axial sealing rib 103, a radial sealing rib 104, a spray hole 105, and a pull ring 106; a sleeve 102 of the same length as the middle area is coaxially arranged in the middle position of the inner pipe; the axial sealing rib 103 is a ring of uniform thickness, with its inner diameter being the same as the outer diameter of the inner pipe 101 and its outer diameter being larger than the outer diameter of the sleeve 102; the axial sealing ribs 103 are respectively arranged along the axial direction of the sleeve 102 at both ends and the middle of the sleeve 102, forming a storage cavity together with the inner pipe 101 and the sleeve 102; the radial sealing rib 104 is a rectangular plate of uniform thickness and length consistent with the sleeve 102, and its length is consistent with the length of the sleeve 102; multiple radial sealing ribs 104 are respectively arranged along the axial direction of the sleeve 102. The circumference of the sleeve 102 is set with equal included angles, and the axial sealing rib 103 together with the inner tube 101 and the sleeve 102 forms a storage cavity that is further divided into multiple storage chambers 107. Each storage chamber 107 has a spray hole 105 on the outer wall of the sleeve. The spray hole 105 is sealed by a pull ring 106. When in use, the pull ring 106 is pulled open, and the foam adhesive pre-stored in the storage chamber will be sprayed out through the spray hole 105 under pressure. The foam adhesive stored in the storage chamber 107 can be made of polyurethane elastic sealing foam material. The sealing form of the spray hole 105 and the pull ring 106 adopts the principle of pull ring opening structure. The specific implementation form can be easily understood by those skilled in the art according to the actual application scenario. The attached drawings of this embodiment are only for brief illustration, and the specific implementation method is not described here.

[0027] Specifically, such as Figure 1-2As shown, the through-wall pipe 1 includes: an inner pipe 101, a sleeve 102, an axial sealing rib 103, a radial sealing rib 104, a spray hole 105, and a pull ring 106. The inner pipe 101 has threads at both ends, and a sleeve 102 of equal length to the middle region is coaxially arranged at the middle position of the inner pipe. The diameter of the inner wall of the sleeve 102 is larger than the diameter of the outer wall of the inner pipe 101. The axial sealing rib 103 starts from the circumference of the outer wall of the inner pipe 101, extends radially along the sleeve 102, and extends outward a certain distance through the outer wall of the sleeve 102. That is, the axial sealing rib 103 is a ring of uniform thickness, with its inner diameter being the same as the outer diameter of the inner pipe 101, and its outer diameter being larger than the outer diameter of the sleeve 102. There are three axial sealing ribs 103, which are respectively arranged along the axial direction of the sleeve 102. The two ends and the middle of the tube 102 together with the inner tube 101 and the sleeve 102 form a storage cavity; the radial sealing rib 104 starts from the projection line of the central axis of the inner tube 101 on the outer wall of the inner tube 101, extends radially along the sleeve 102 and extends outward through the outer wall of the sleeve 102 for a certain distance, that is, the radial sealing rib 104 is a rectangular plate with a uniform thickness and a length consistent with the sleeve 102, and its length is consistent with the length of the sleeve 102; there are 3 radial sealing ribs 104, which are set at equal included angles (120°) along the circumference of the sleeve 102, and the axial sealing rib 103 together with the inner tube 101 and the sleeve 102 further divides the storage cavity into 6 storage chambers; preferably, the circumferential width of the axial sealing rib 103 is greater than the rectangular width of the radial sealing rib 104.

[0028] By setting the radial sealing diameter and axial sealing ribs as described above, the storage cavity can be divided into 6 storage chambers. These chambers are used to pre-store waterproof foam adhesive. Each storage chamber has a nozzle 105 on the outer wall of its corresponding sleeve. The nozzle 105 is sealed by a pull ring 106. When in use, pulling the pull ring 106 releases the pre-stored foam adhesive through the nozzle 105 under pressure, thus filling the gap between the through-wall pipe 1 and the wall opening, achieving waterproofing of the wall. During construction, the through-wall pipe 1 is first placed in the wall opening, then the pull rings 106 are pulled out. After the foam adhesive evenly fills the gap between the pipe and the wall opening and cures, the sealing gasket 4 and the fixed end cap 3 are installed.

[0029] like Figure 3 As shown, the waterproof pipe structure in this embodiment pre-stores foam adhesive in the through-wall pipe 1. When the through-wall pipe 1 is placed in the wall opening, the pull ring 106 is pulled to achieve automatic filling of foam adhesive. Compared with manual application of foam adhesive, this solves the technical problems of insufficient space and insufficient or uneven filling of foam adhesive during manual construction. It improves work efficiency and enhances the sealing performance of the foam adhesive.

[0030] like Figure 4As shown, it also includes a fixed end cap 3 and a sealing gasket 4. The sealing gasket 4 is installed at both ends of the through-wall pipe 1. After installation, one side of the sealing gasket 4 abuts against the axial sealing rib 103, and the other side abuts against the fixed end cap 3. Simultaneously, the outer ring abuts against the wall of the opening in the wall. Because the sealing gasket 4 is made of elastic rubber, this installation method allows the sealing gasket 4 to effectively fill the gap between the two ends of the through-wall pipe 1 and the wall opening, improving its water-resistant capability. The sealing gasket 4 can be made of water-absorbing and expanding rubber, ensuring that when water enters, the sealing gaskets 4 at both ends will absorb water and expand, further enhancing their water-blocking characteristics. The fixed end caps are fixed to both ends of the through-wall pipe 1 via threaded connections, achieving the fixation of the through-wall pipe 1 without drilling holes in the wall, simplifying construction.

[0031] As can be seen from the accompanying drawings, in the embodiments of this utility model, the fixed connection and relative sliding of each component can be achieved by conventional methods of the prior art. The specific implementation method will not be further described in this utility model specification.

[0032] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
