Description

Technical Field

[0001] The present application relates to the technical field of wall hole plugging, and in particular to a wall hole plugging hoop. Background Art

[0002] During installation, the supply and return water pipes of the central air conditioner will pass through the wall. According to the specifications, sleeves need to be installed at the nodes where the supply and return water pipes pass through the wall. That is, a hole is opened in the wall, and the supply and return water pipes pass through the hole. The gap between the hole and the supply and return water pipes is filled by fire-proof sealing. That is, non-combustible materials and sleeves with a fire resistance level equivalent to the floor wall are used to seal the hole to form a fire-proof sealing layer.

[0003] Since the service life of central air conditioning is very long, especially in the cooling period in summer, the water temperature is relatively low. The low-temperature water enters the supply and return water pipes, which reduces the temperature of the outer surface of the supply and return water pipes. At this time, the outer surface of the supply and return water pipes will be exposed to the air and condensation will occur, or even dripping will occur. These dew or water droplets will drip on the wall or fireproof sealing materials, causing the fireproof sealing of the wall hole to become loose after long-term use, which in turn may cause the fireproof sealing to become loose. Summary of the invention

[0004] The embodiment of the present application provides a wall hole sealing hoop to solve the problem of condensation or even dripping on the water supply and return pipes in the related art.

[0005] In a first aspect, a wall hole sealing hoop is provided, which comprises:

[0006] Hole in the wall;

[0007] Water supply and return pipes, which pass through the wall holes;

[0008] A fireproof sealing layer, the fireproof sealing layer is located in the wall hole, and the fireproof sealing layer is used to fill the wall hole;

[0009] The insulation layer is arranged closely against the outer wall of the water supply and return pipes, and the insulation layer extends from the wall hole to a direction away from the wall hole.

[0010] Some embodiments further include a heat-insulating hoop;

[0011] The heat-insulating hoop is arranged around the outside of the heat-insulating layer, the heat-insulating hoop is arranged close to the wall hole, and the heat-insulating hoop covers the fireproof sealing layer.

[0012] In some embodiments, the insulation hoop and the insulation layer are connected by insulation glue.

[0013] In some embodiments, the thermal insulation layer passes through the wall hole, and the fireproof sealing layer is in close contact with the thermal insulation layer.

[0014] The embodiment of the present application provides a wall hole sealing hoop. Since the present application provides an insulation layer on the supply and return water pipes in addition to using conventional wall hole fire-proof sealing, the insulation layer is wrapped around the junction between the supply and return water pipes and the wall. Therefore, when water with lower temperature passes through the supply and return water pipes, the temperature of the outer wall of the supply and return water pipes decreases. The insulation layer prevents the outer wall of the supply and return water pipes near the wall from directly contacting the air, so condensation will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] The embodiment of the present application provides a wall hole sealing hoop, which can solve the problem of condensation or even dripping on the water supply and return pipes in the related art.

[0021] See also Figure 1 to Figure 2 , a wall hole sealing hoop, comprising:

[0022] A wall hole 1 is provided on the wall.

[0023] A water supply and return pipe 2, the water supply and return pipe 2 passes through the wall hole 1;

[0024] A fireproof sealing layer 3, the fireproof sealing layer 3 is located in the wall hole 1, and the fireproof sealing layer 3 is used to fill the wall hole 1;

[0025] The insulation layer 4 is specifically a rubber insulation sleeve, and the insulation layer 4 is arranged closely to the outer wall of the water supply and return pipe 2, and the insulation layer 4 extends from the wall hole 1 to a direction away from the wall hole 1;

[0026] Also includes a heat-insulating hoop 5;

[0027] The heat-insulating hoop 5 is arranged around the outside of the heat-insulating layer 4, the heat-insulating hoop 5 is arranged close to the wall hole 1, and the heat-insulating hoop 5 covers the fireproof sealing layer 3;

[0028] The heat-insulating hoop 5 and the heat-insulating layer 4 are connected by heat-insulating glue.

[0029] The heat-insulating layer 4 passes through the wall hole 1 , and the fire-proof sealing layer 3 is in close contact with the heat-insulating layer 4 .

[0030] The installation of the water supply and return pipe 2 is to first open a wall hole 1 on the wall, then put an insulation layer 4 on the water supply and return pipe 2, then pass the water supply and return pipe 2 through the wall hole 1, and fill the wall hole 1 with a fireproof sealing layer 3 to fix the water supply and return pipe 2, and finally fix the insulation hoop 5 outside the insulation layer 4 with insulation glue, and the insulation hoop 5 is set close to the wall.

[0031] When the water supply and return pipe 2 is fixed, the insulation layer 4 extends from the junction of the water supply and return pipe 2 and the wall to the direction away from the wall hole 1. At this time, there are two situations of the distribution of the insulation layer 4. The first situation is that there is no insulation layer 4 between the water supply and return pipe 2 and the inner wall of the wall hole 1, that is, the gap between the water supply and return pipe 2 and the inner wall of the wall hole 1 is filled with the fireproof sealing layer 3. The second situation is that the insulation layer 4 passes through the wall hole 1, that is, the fireproof sealing layer 3 can only fill the gap between the insulation layer 4 and the inner wall of the wall hole 1. Figure 2 As shown, the above two situations can prevent the outer surface of the water supply and return pipe 2 near the wall from directly contacting the air, thereby preventing the condensation on the outer wall of the water supply and return pipe 2 from contacting the wall or the fireproof sealing layer 3;

[0032] In the first of the above two situations, gaps will appear between the non-combustible materials of the fireproof sealing layer 3 under long-term use, causing air to enter from these gaps and contact the sleeve, and the sleeve is in direct contact with the outer wall of the water supply and return pipe 2, resulting in a decrease in the temperature of the outer wall of the sleeve. The temperature of the outer wall of the sleeve is lower than the temperature of the outside air in summer, and there is still a possibility of condensation on the outer wall of the sleeve. When condensation occurs on the outer wall of the pipe, the fireproof sealing layer 3 will become looser, and finally the air conditioning refrigeration effect will be weakened. If the second situation is adopted, there is another insulation layer 4 between the sleeve and the water supply and return pipe 2, which can avoid the problem of condensation on the outer wall of the pipe as much as possible, and further extend the service life. Therefore, the second situation will be selected for construction when installing the water supply and return pipe 2;

[0033] The larger the nominal diameter of the water supply and return pipe 2, the more the flow of cold water, which will lead to the lower outer surface temperature of the water supply and return pipe 2. In order to ensure that the insulation layer 4 can effectively insulate, the relationship between the thickness of the insulation layer 4 and the nominal diameter of the water supply and return pipe 2 is as follows: when the nominal diameter of the water supply and return pipe 2 is less than or equal to 20mm, the thickness of the insulation layer 4 is 25mm; when the nominal diameter of the water supply and return pipe 2 is 25mm to 40mm, the thickness of the insulation layer 4 is 28mm; when the nominal diameter of the water supply and return pipe 2 is 50mm to 125mm, the thickness of the insulation layer 4 is 32mm; when the nominal diameter of the water supply and return pipe 2 is 150mm to 400mm, the thickness of the insulation layer 4 is 36mm; when the nominal diameter of the water supply and return pipe 2 is greater than or equal to 400mm, the thickness of the insulation layer 4 is 40mm;

[0034] The construction is performed according to the relationship between the above-mentioned insulation layer 4 and the nominal diameter of the water supply and return pipe 2. The insulation layer 4 cannot completely cover the fireproof sealing layer 3. The fireproof sealing layer 3 exposed to the air will become loose and not beautiful after a long time. Therefore, an insulation hoop 5 is arranged outside the insulation layer 4. The insulation hoop 5 completely covers the fireproof sealing layer 3. At the same time, the insulation hoop 5 isolates the fireproof sealing layer 3 from the air, thereby extending the service life of the fireproof sealing layer 3.
