Description

Technical Field

[0001] The utility model relates to the technical field of passive house wall-penetrating sleeve installation, in particular to an airtight structure of a passive wall-penetrating sleeve. Background Art

[0002] Passive buildings use extra-thick insulation materials and complex doors and windows, and mainly achieve efficient thermal insulation through the construction of the house itself. They use solar energy and heat dissipation from home appliances to provide heat sources for the rooms, reducing or eliminating the use of actively supplied energy. Even if other energy sources are needed, clean renewable energy is used as much as possible.

[0003] As the weather changes from hot to cold, the reserved holes in the wall expand and contract due to heat and cold, and the tightness between the wall sleeve installed in the reserved hole and the wall changes, affecting the overall sealing effect. In addition, once the sealing between the wall sleeve and the wall is reduced, outdoor moisture can easily enter the room, affecting the indoor dry environment. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an airtight structure of a passive wall-penetrating sleeve, which overcomes the deficiencies of the prior art and effectively solves the problem that the sealing effect of the wall-penetrating sleeve is weakened and outdoor moisture is easily discharged into the room.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The airtight structure of the passive wall bushing includes a buffer plate, a circular opening is opened inside the buffer plate, and the inner wall of the circular opening is provided with symmetrically distributed asbestos insulation sleeves, and the inner wall of the buffer plate is provided with sealing rings on both sides of the asbestos insulation sleeves;

[0007] The outer wall of one side of the buffer plate is bonded with a waterproof and air-proof membrane on one side of one of the sealing rings, and the outer wall of the other side of the buffer plate is bonded with a waterproof and breathable membrane on one side of the other sealing ring. The waterproof and air-proof membrane and the outer wall of one side of the waterproof and breathable membrane are both bonded with binding tapes.

[0008] Preferably, a wall bushing body is slidably connected between the symmetrically distributed asbestos insulation sleeve panels.

[0009] Preferably, the sum of the thickness of the asbestos insulation sleeve and the two sealing rings matches the thickness of the buffer plate.

[0010] Preferably, a passive wall is arranged outside the buffer plate, and a rectangular opening is opened on the inner wall of the passive wall, and the buffer plate is arranged inside the rectangular opening.

[0011] Preferably, a sealant layer is filled between the wall sleeve body and the buffer plate.

[0012] Preferably, the outer walls of one side of the waterproof and air-barrier membrane and the waterproof and breathable membrane are both provided with folded edges, and the binding tape is bonded to the outer wall of the folded edges.

[0013] Preferably, the waterproof and air-barrier membrane and the waterproof and air-permeable membrane are respectively arranged indoors and outdoors of the passive wall.

[0014] The beneficial effects of the utility model are:

[0015] 1. The airtight structure of the passive wall bushing of this design is to first open a rectangular opening inside the passive wall to load a buffer plate. The buffer plate can increase a certain toughness to compensate for the gap. At the same time, since the main body of the wall bushing is installed between two asbestos insulation sleeves and sealed by a sealing ring, a multi-layer sealing structure can be added under the condition of providing insulation to prevent thermal expansion and contraction, which greatly improves the overall airtightness effect and is conducive to meeting the airtightness requirements of the main body of the wall bushing;

[0016] 2. The airtight structure of the passive wall sleeve of this design has a waterproof and air-tight membrane and a waterproof and breathable membrane on both sides of the inner part of the passive wall. The waterproof and air-tight membrane and the waterproof and breathable membrane act on indoor and outdoor respectively, blocking water vapor from entering the room and affecting the indoor dry environment, which is conducive to ensuring the stability of the indoor environment and has the characteristics of energy saving and emission reduction.
