Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a double anti-leakage device for a wall hole. Background Art

[0002] In recent years, due to environmental factors such as global warming, high temperatures in summer and cold winters, the installation and use of air conditioners has also increased. At present, the trend of urbanization is accelerating, and high-rise residential buildings are becoming more and more popular, with each household installing about 1-3 units. While enjoying the comfortable life brought by air conditioning, there is a common problem of leakage in the air conditioning pipe holes, which cannot be effectively solved; at this stage, the traditional method of tilting the air conditioning pipe holes or filling with foaming agents is widely used. However, its shortcomings are also increasingly criticized. For example, the tilting hole method cannot guarantee that the tilted hole that meets the process requirements can be opened according to the process requirements due to human construction, and it is still impossible to eliminate the phenomenon of leakage in the air conditioning pipe holes. At the same time, the tilted hole that meets the process requirements has a weak inhibitory effect on the backflow of air conditioning pipes; the hole filling foaming agent can prevent rainwater backflow and wall leakage, but it brings many inconveniences to subsequent disassembly and maintenance.

[0003] For example, a Chinese patent with the authorization announcement number CN212377470U discloses an external wall anti-leakage system structure, which relates to the field of building structure technology, including a removable elastic sleeve wrapped on the outer surface of the wall-penetrating pipe body, and the sleeve is a spliced ​​structure, and also includes a sealing ring bolted to the outside and inside of the external wall and corresponding to the hole position, the sealing ring includes a ring plate bolted to the external wall surface, and the inner wall of the ring plate is fixedly installed with an annular sleeve. The utility model elastically wraps the outside of the pipe body through the sleeve, and the sleeve can adapt to the thermal expansion and contraction of the pipe body. The holes on the inner and outer surfaces of the external wall are bolted with sealing rings to ensure the sealing of the hole gap. At the same time, the auxiliary seal seals the openings of the sleeve and the annular sleeve inside the hole, thereby ensuring the sealing of the hole position. The external wall anti-leakage treatment is achieved through structural coordination, which has the advantage of easy construction while ensuring the sealing.

[0004] For another example, a Chinese patent with the authorization announcement number CN212616804U discloses an anti-leakage sleeve for an opening in an exterior wall of a building, comprising an opening on an exterior wall, a through-wall pipe running through the opening, and mortar filled between the inside of the opening and the outside of the through-wall pipe, the right side of the exterior wall being the exterior wall surface, an anti-leakage mechanism being arranged on the through-wall pipe, the anti-leakage mechanism comprising an annular plate movably sleeved on the through-wall pipe, and the left side of the annular plate being fixedly connected to the right side of the exterior wall by screws, the left side of the annular plate being movably contacted with a hollow elastic sealing ring, the hollow elastic sealing ring being located in the opening, and a short sleeve being arranged on the left side of the hollow elastic sealing ring. The utility model has a reasonable design, and is convenient for achieving a plugging effect by compressing the hollow elastic sealing ring to deform and expand it, and the tighter the compression, the stronger the plugging effect, so as to effectively prevent rainwater from infiltrating through the opening to the left, and achieve the purpose of stable plugging and anti-leakage, which is convenient for use.

[0005] Although the above two solutions solve the corresponding technical problems, both of them have the defects of complex structure, high cost and troublesome construction. Therefore, a double anti-leakage device for wall holes is proposed. Utility Model Content

[0035] Example 1

[0036] The double anti-leakage device for wall holes provided in this embodiment is as follows: Figure 1-Figure 4 As shown, it includes: a wall hole plug 1 and a fixing member for fixing the wall hole plug 1 in the wall hole.

[0037] The wall hole plug 1 includes a sleeve 101, an annular plate 102 and an elastic rubber soft membrane 2. The sleeve 101 is inserted into a wall hole opened on the wall. The annular plate 102 is fixedly installed at one end of the sleeve 101 close to the outer side of the wall. The elastic rubber soft membrane 2 is fixedly installed inside the sleeve 101, and a through hole 201 for inserting an air conditioning pipe is reserved at the center of the elastic rubber soft membrane 2. The diameter of the through hole 201 is smaller than the outer diameter of the air conditioning pipe, so that a sealed connection can be achieved between the through hole 201 and the air conditioning pipe.

[0038] Among them, the fixing part includes an adhesive layer 3, which is simultaneously coated on the outer side surface of the sleeve 101 and the side surface of the annular plate 102 facing the inner side surface of the wall. The sleeve 101 is sealed and fixedly connected to the inner wall of the wall hole through the adhesive layer 3, and the annular plate 102 is sealed and fixedly connected to the outer side surface of the wall through the adhesive layer 3.

[0039] The double anti-leakage device for wall holes using the above technical solution is mainly composed of a wall hole plug 1 and a fixing part for fixing the wall hole plug 1 in the wall hole. The elastic rubber soft membrane 2 is provided to form a first anti-leakage protection with the air-conditioning pipe, which can tightly wrap the air-conditioning pipe body to prevent the air-conditioning pipe from carrying backflow rainwater into the wall hole. The wall hole plug 1 is provided to form a second anti-leakage protection with the adhesive layer 3 and the inner wall of the wall hole, so that the wall hole forms an overall sealed and waterproof seal, which can prevent water seepage between the main surface of the outer wall and the wall hole. The double anti-leakage device for wall holes is innovative compared to the traditional anti-leakage technology for air-conditioning holes. It can actively prevent and eliminate the hidden dangers of leakage of air-conditioning holes during the construction stage. It is simple to operate, convenient to install, simple in structure, and low in cost. It can be mutually supplemented with the exterior wall insulation construction process and is suitable for ordinary house construction projects.

[0040] In order to increase the service life of the wall hole plug 1, the sleeve 101 and the annular plate 102 are integrally formed by using PVC material through an injection molding process.

[0041] Specifically, in the present embodiment, the adhesive layer 3 is preferably a double-sided self-adhesive butyl waterproof tape layer, which has the advantages of good aging resistance and weather resistance. The butyl waterproof tape adopts high-quality raw materials and advanced production technology, and has good aging resistance and weather resistance. After long-term use and exposure, it can still maintain a good sealing effect. At the same time, it has the advantage of good chemical corrosion resistance. The main component of the butyl waterproof tape is butyl rubber, which has excellent chemical corrosion resistance. It can be used for a long time in various strong acids, strong alkalis and other chemical media without corrosion.

[0042] In order to prevent the outer surface of the adhesive layer 3 from being stained with dust and affecting its adhesion, a release film is attached to the outer surface of the adhesive layer 3 .

[0043] Example 2

[0044] The difference between this embodiment and embodiment 1 is that an annular retaining ring 4 is fixedly installed inside the sleeve 101, and a side of the annular retaining ring 4 facing the annular plate 102 is fixed and sealed to a side of the elastic rubber soft membrane 2 facing the inner side of the wall.

[0045] By providing the annular retaining ring 4 , the elastic rubber soft membrane 2 can be stably installed inside the sleeve 101 , thereby improving the sealing performance of the elastic rubber soft membrane 2 .

[0046] Example 3

[0047] The difference between this embodiment and the second embodiment is that an annular rubber sealing airbag 5 is fixedly installed inside the sleeve 101 , and the annular rubber sealing airbag 5 is arranged on the side of the annular retaining ring 4 away from the elastic rubber soft membrane 2 .

[0048] The annular rubber sealing airbag 5 can further improve the anti-leakage performance of the double anti-leakage device for the wall hole.

[0049] In order to adjust the sealing performance between the annular rubber sealing airbag 5 and the air-conditioning pipe, a valve nozzle 501 is embedded on the side of the annular rubber sealing airbag 5 away from the annular retaining ring 4. The needle of a syringe can be inserted into the valve nozzle 501 to adjust the air pressure in the annular rubber sealing airbag 5, thereby achieving the purpose of adjusting the sealing performance between the annular rubber sealing airbag 5 and the air-conditioning pipe. When the annular rubber sealing airbag 5 is inflated with a syringe, the sealing performance between the annular rubber sealing airbag 5 and the air-conditioning pipe can be improved. When the air in the annular rubber sealing airbag 5 is extracted with a syringe, the sealing performance between the annular rubber sealing airbag 5 and the air-conditioning pipe can be reduced. Therefore, the double anti-leakage device for the wall hole can be adapted to the installation of air-conditioning pipes with different outer diameters.

[0050] In order to improve the sealing performance of the annular rubber sealing airbag 5 , the cross section of the annular rubber sealing airbag 5 is D-shaped, and the inner annular surface of the annular rubber sealing airbag 5 is an arc surface.

[0051] In order to ensure the sealing performance of the annular rubber sealing airbag 5, the inner ring diameter of the annular rubber sealing airbag 5 is set to be smaller than the outer diameter of the air conditioning pipe.

[0052] In summary, the double anti-leakage device for wall holes provided in this embodiment, when used:

[0053] Combination Figure 5 As shown, before the construction of the external wall insulation layer, the release film on the outer side of the adhesive layer 3 is torn off, and then the sleeve 101 is inserted into the wall hole opened on the wall, and the sleeve 101 is sealed and fixedly connected with the inner wall of the wall hole through the adhesive layer 3, and the annular plate 102 is sealed and fixedly connected with the outer side of the wall through the adhesive layer 3, and then the external wall insulation layer can be constructed;

[0054] The elastic rubber soft membrane 2 is provided to form a first layer of anti-leakage protection with the air-conditioning pipe, which can tightly wrap the air-conditioning pipe body to prevent the air-conditioning pipe from carrying backflow rainwater into the wall hole. The wall hole plug 1 is provided to form a second layer of anti-leakage protection with the adhesive layer 3 and the inner wall of the wall hole, so that the wall hole forms an overall sealed and waterproof structure, which can prevent water seepage between the external wall insulation layer on the outer side of the wall and the wall hole. The double anti-leakage device for wall holes is innovative compared to the traditional anti-leakage technology for air-conditioning holes. It can actively prevent and eliminate the hidden dangers of leakage of air-conditioning holes during the construction stage. It is simple to operate, easy to install, simple in structure, and low in cost. It can be connected with the external wall insulation construction process to assist each other, and is suitable for ordinary house construction projects.

[0055] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
