Description

Technical Field

[0001] The utility model belongs to the technical field of anti-leakage structures, and specifically relates to an anti-leakage structure for vertical plate-penetrating pipes in a residence. Background Art

[0002] Residential water supply, gas supply and ventilation all require pre-buried pipes in the wall, which are designed to penetrate the wall at different locations according to the needs. Among them, the vertical pipe needs to penetrate the entire ceiling, and there is a gap between the outer wall and the wall, which is prone to leakage. Waterproofing is often required after installation. Before the pipe is buried in the house, it is often laid in the rough house and then the waterproof layer is poured. Compared with the waterproof coating measures of traditional residential buildings, the through holes used for vertical pipes generally require the addition of fillers such as acrylic esters in the cement mortar, so that a waterproof membrane is formed after mixing.

[0003] The Chinese utility model patent with publication number CN217502932U, published on September 27, 2022, discloses a leak-proof reinforced concrete pipe interface, which relates to the field of municipal pipe jacking engineering technology. The reinforced concrete pipe interface includes: a first pipe, a second pipe, a composite wood board cushion, a steel ring, and a wedge-shaped rubber ring. The inner side of the end of the first pipe is provided with a composite wood board cushion, and the outer side of the end of the first pipe is welded with a steel ring; the end of the second pipe is provided with a socket pre-groove, and the socket pre-groove is provided with a wedge-shaped rubber ring, and the socket pre-groove provided with the wedge-shaped rubber ring is inserted into the steel ring.

[0004] According to the above patent, the pipe interface can reduce corrosion on the pipe surface, effectively prevent leakage at the pipe interface, and reduce maintenance costs caused by pipe leakage. However, the surface of the HDPE membrane and filler is rough after pouring and hardening, and gaps are easily generated at the contact position with the vertical pipe, leaving a risk of micro-leakage in the anti-leakage structure outside the vertical pipe. Utility Model Content

[0005] The utility model aims to provide a residential vertical through-plate pipe anti-leakage structure, which can press the flexible sleeve inwardly against the pre-buried outer sheath pipe to reduce the gap and reduce the occurrence of micro-leakage hidden dangers at the anti-leakage structure.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A residential vertical through-plate pipeline anti-leakage structure comprises a pre-buried outer sheath tube and a flexible sleeve, wherein the flexible sleeve is fixed to the outer periphery of the pre-buried outer sheath tube, an inert gas bag, an elastic belt and an alloy ring are arranged inside the flexible sleeve, the inert gas bag is annular and coaxial with the flexible sleeve; the elastic belt is arc-shaped, arranged between the flexible sleeve and the inert gas bag, and the two ends of the elastic belt are respectively abutted against the top and bottom of the inner wall of the flexible sleeve; a plurality of elastic belts are evenly fixed to the outer wall of the alloy ring, and the inner wall of the alloy ring is fixed to the inner wall of the flexible sleeve.

[0008] Furthermore, the inner ring of the alloy ring is fixed to one end of multiple support rods, the other end of the support rod passes through the flexible sleeve and is fixed to the outer wall of one side of the plastic ring, the outer wall of the other side of the plastic ring is fixed to the outer periphery of the alkali-resistant mesh cloth, and the inner periphery of the alkali-resistant mesh cloth is fixed to the outer periphery of the embedded outer sheath tube.

[0009] Furthermore, disc portions are fixed at both ends of the elastic band.

[0012] 1. The utility model can push the flexible sleeve inwardly and closely to the pre-buried outer sheath tube to reduce the gap and reduce the hidden danger of micro-seam leakage in the anti-leakage structure.

[0013] 2. When using the utility model, the embedded outer sheath tube is fixed to the through hole of the wall, and its two ends are passed out, while the flexible sleeve, the inert gas bag, a plurality of elastic bands and the support rod are left inside the through hole of the wall as a soft and tight bushing.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-Figure 5 As shown, the residential vertical through-plate pipeline anti-leakage structure of this embodiment includes a pre-buried outer sheath tube 1 and a flexible sleeve 2. The flexible sleeve 2 is fixed to the outer periphery of the pre-buried outer sheath tube 1. An inert gas bag 3, an elastic band 4 and an alloy ring 6 are arranged inside the flexible sleeve 2. The inert gas bag 3 is annular and coaxial with the flexible sleeve 2; the elastic band 4 is arc-shaped, and the elastic band 4 is arranged between the flexible sleeve 2 and the inert gas bag 3, and the two ends of the elastic band 4 are respectively abutted against the top and bottom of the inner wall of the flexible sleeve 2; a plurality of elastic bands 4 are evenly fixed to the outer wall of the alloy ring 6, and the inner wall of the alloy ring 6 is fixed to the inner wall of the flexible sleeve 2.

[0024] When burying the vertical pipeline, the embedded outer sheath tube 1 is fixed to the through hole of the wall, and its two ends are passed out, while the flexible sleeve 2 and the inert gas bag 3 are left inside the through hole of the wall as a soft and tight bushing. After pouring the filling material, the soft and tight bushing is squeezed inward to fit tightly against the embedded outer sheath tube 1, and the two ends of the embedded outer sheath tube 1 can be connected to the pipeline to form a complete vertical through-plate pipeline, thereby reducing the gap and reducing the hidden danger of micro-leakage in the anti-leakage structure. At the same time, the elastic belt 4 can pull the flexible sleeve 2 and the inert gas bag 3 to shrink vertically and extend horizontally, so as to adaptively fill the gap and continuously seal to prevent water leakage and air leakage.

[0025] Furthermore, the inner ring of the alloy ring 6 is fixed to one end of the plurality of support rods 5, the other end of the support rod 5 passes through the flexible sleeve 2 and is fixed to the outer wall of one side of the plastic ring 7, the outer wall of the other side of the plastic ring 7 is fixed to the outer periphery of the alkali-resistant mesh cloth 8, and the inner periphery of the alkali-resistant mesh cloth 8 is fixed to the outer periphery of the embedded outer sheath tube 1.

[0026] The alloy ring 6 supports each support rod 5 so as to stretch the flexible sleeve 2 at multiple points to maintain its shape; the plastic ring 7 is fixedly connected to increase the area where the support rod 5 is fixed, while leaving enough space for the flexible sleeve 2 to deform; the alkali-resistant mesh cloth 8 makes the connection between the filler and the embedded outer sheath tube 1 more dense and firm.

[0027] Furthermore, disc portions 9 are fixed at both ends of the elastic band 4 .

[0028] The disc portion 9 can increase the area of ​​the connection between the elastic band 4 and the flexible sleeve 2, thereby strengthening the connection between the elastic band 4 and the flexible sleeve 2 and reducing the possibility of breakage of the connection.

[0029] Furthermore, sealing rubber rings 10 are provided at both ends of the embedded outer sheath tube 1 .

[0030] After the pre-buried outer sheath tube 1 passes through the board and is cast and fixed, the two sealing rubber rings 10 can be used to stick to the upper and lower surfaces of the floor slab respectively to protect the root of the pre-buried outer sheath tube 1 and improve its anti-leakage performance.

[0031] The working principle of this utility is:

[0032] When burying the vertical pipeline, the pre-buried outer sheath 1 is fixed in the wall through hole, with its two ends passing through, while the flexible sleeve 2, the inert gas bag 3, several elastic bands 4 and the support rod 5 are all left inside the wall through hole as a soft and tight bushing.

[0033] After pouring the filling material, the soft and tight bushing is squeezed inward to fit tightly against the embedded outer sheath tube 1, and the two ends of the embedded outer sheath tube 1 can be connected to the pipeline to form a complete vertical through-plate pipeline, reducing gaps and reducing the occurrence of micro-leakage hazards in the anti-leakage structure.

[0034] At the same time, the elastic band 4 can pull the flexible sleeve 2 and the inert gas bag 3 to shrink vertically and extend horizontally, so as to adaptively fill the gaps and continuously seal to prevent water and air leakage.

[0035] The above is only a preferred implementation of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
