Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Example 1
As shown in fig. 1, the embodiment provides a wall-through opening structure, which includes a wall-through pipe 1 and a wall-through sleeve 2, wherein the wall-through pipe extends into the wall-through sleeve and extends to the outside;
the first heat preservation layer 3 is filled between the wall penetrating pipe and the wall penetrating sleeve;
and the supporting structure 4 is arranged at a pipe orifice at one end of the wall bushing 2, one end of the supporting structure 4 is connected with the pipe orifice at one end of the wall bushing 2, and the opposite end of the supporting structure (4) extends along the direction far away from the wall bushing 1.
The through-wall opening structure is used for through-wall opening nodes of a wall body during construction, so that the operation process of arranging structures such as through-wall pipes in the wall body by a conventional construction method is omitted, the construction process is simplified, and the construction efficiency is improved; meanwhile, the production process of the structure is independent of the construction process of the wall body, and standardized production can be carried out in advance in a factory, so that the quality can be effectively controlled, and each produced structure is guaranteed to have good air tightness and a heat bridge breaking effect.
Furthermore, the wall-through opening structure further comprises a waterproof and vapor-permeable membrane 5 which is arranged at the pipe orifice at one end of the wall-through sleeve 2 and partially covers the supporting structure 4 and the outer wall of the wall-through pipe 1 so as to seal the pipe orifice. The through-wall opening structure is used for the through-wall opening node of the wall body, and the waterproof and breathable film can be prevented from being paved in the construction process, so that the construction time is shortened, and the construction efficiency is improved. The supporting structure in this embodiment is used to facilitate the laying of the waterproof and breathable film.
It will be understood that the waterproof and vapor-permeable membrane 5 partially covering the support structure 4 is not bonded to the surface of the support structure 4 parallel to the axial direction of the wall bushing, the bonding of this surface affecting the contact of the support structure 4 with the concrete layer 8 disposed on its periphery, so that the air-tightness and thermal bridge cut-off effect are affected in this position; similarly, when the supporting structure 4 and the outer wall of the wall bushing 2 form an acute angle, the waterproof vapor-permeable membrane 5 adhered to the supporting structure 4 affects the contact between the supporting structure 4 and the concrete layer 8 arranged on the periphery of the supporting structure 4, and therefore, the supporting structure 4 preferably forms an obtuse angle or a right angle with the outer wall of the wall bushing 2; the support structure 4 is preferably arranged at a right angle to the outer wall of the wall bushing 2, which facilitates the arrangement of the second insulating layer 7 in the wall.
As a specific embodiment, the support structure 4 has a length of 3cm to 10 cm. The length of the support structure 4 is related to the degree of adhesion stability of the waterproof and vapor-permeable membrane 5. When the supporting structure 4 is short, the sticking area of the waterproof and breathable film 5 on the supporting structure 4 is low, so that the sticking of the waterproof and breathable film 5 is inconvenient, and the sticking effect cannot be ensured, thereby having adverse effects on the air tightness and the heat bridge cutoff effect at the through-wall hole node of the wall body; when the supporting structure 4 is long, the sticking of the waterproof and breathable film 5 is facilitated, but the size of the through-wall opening structure is increased, the construction process of the through-wall opening node of the wall body is not facilitated, and the cost is increased; therefore, the length of the supporting structure 4 is suitable for not only being beneficial to the adhesion of the waterproof and breathable film 5 and ensuring the adhesion effect, but also controlling the size of the through-wall opening structure and being beneficial to the construction process of the through-wall opening node of the wall body.
Further, the thickness of the first heat-insulating layer 3 is 3cm to 20 cm. The thickness is also the size of the gap between the wall bushing 1 and the wall bushing 2. When the thickness is small, it is difficult to fill the first heat-insulating material between the wall-penetrating pipe 1 and the wall-penetrating sleeve 2, and the heat-insulating effect is affected due to the insufficient uniform and compact filling and insufficient thickness; when the thickness is large, the cost is high, and the waste of the first heat insulating material is also caused.
As an alternative embodiment, the supporting structure 4 may be fixedly connected to an end opening of the wall bushing 2, or may be integrally formed with the wall bushing 2, which may be selected according to the actual situation.
In order to ensure that the first heat-insulating materials at all the positions on the periphery of the wall-penetrating pipe 1 have good heat-insulating effect, the axial direction of the wall-penetrating sleeve 2 is the same as that of the wall-penetrating pipe 1, so that the thicknesses of the first heat-insulating materials at all the positions are the same.
Specifically, the first heat-insulating layer 3 is made of heat-insulating cotton, rock wool felt or polyurethane special for pipelines. It should be understood that other materials with good thermal insulation effect are also within the scope of the present application. The material of the through-wall pipe 1 includes but is not limited to PVC pipe or PP pipe; the material of the wall bushing 2 includes but is not limited to PVC pipe or PP pipe.
It should be understood that the through-wall opening structure is not only applicable to passive buildings, but also applicable to other energy-saving building fields.

Furthermore, the second insulating layer 7 is formed by splicing a plurality of insulating materials, and a zigzag joint mark is formed at the splicing position along a direction vertical to the second insulating layer 7; preferably, the zigzag seam may be formed by a mortise and tenon structure; this connected mode is favorable to strengthening the connection stability of third insulation material on the one hand, makes the concatenation of second heat preservation 7 more firm, and on the other hand can realize the fissure of displacement processing of second heat preservation 7 to reduce the cold bridge of third insulation material junction, and prolonged the heat and circulated to outdoor route along the junction, thereby guaranteed the heat preservation effect of second heat preservation 7. The third insulation material includes, but is not limited to, graphite polystyrene board, extruded polystyrene board, molded polystyrene board, extruded graphite board or rock wool composite board, and other materials with good insulation effect are also suitable for the structure, such as composite insulation material.
The second insulating layer 7 can be adhered to the supporting structure 4 and the concrete layer 8, and the second insulating layer 7 can also be fixedly connected with a steel bar structure of the concrete layer 8; preferably, the connection is fixed, the connection mode can effectively enhance the connection strength between the second heat-insulating layer 7 and the concrete layer 8, and the third heat-insulating material is prevented from falling off from the concrete layer 8, so that the stability of the heat-insulating capacity of the wall body is ensured.

The first plastering layer 10 and the second plastering layer 11 comprise a first mortar layer, an alkali-resistant glass fiber net and a second mortar layer which are stacked, and the thickness of the first plastering layer and the second plastering layer is 3 mm-6 mm. The first surface coating layer 10 can protect the second heat-insulating layer 7, prevent the second heat-insulating layer 7 from cracking, and improve the impact resistance and durability of the second heat-insulating layer.
Furthermore, a pre-pressed expansion sealing tape 12 is arranged at the joint of the wall penetrating pipe 1 and the second insulating layer 7 to ensure the sealing property and the waterproof property of the joint of the wall penetrating pipe 1 and the second insulating layer 7; the outside of the prepressing expansion sealing strip 12 is provided with a sealant 13, the sealant 13 can be a silicone sealant, and the silicone sealant has strong bonding force, large tensile strength and good seepage-proofing and leakage-proofing effects. The prepressing expansion sealing strip 12 and the sealant 13 at the position are matched with the waterproof steam-proof membrane 6 and the waterproof steam-permeable membrane 5 in the wall-through hole structure, so that the wall body has a good waterproof effect, and the wall body cannot generate a rainwater leakage phenomenon even under the condition of storm.
In order to further reduce the heat loss, as shown in fig. 3, the wall body may further include a third insulating layer 9 disposed on the outer wall of the wall penetrating pipe 1 away from the second insulating layer 7 and covering the surface of the insulating vapor barrier; the material of the third insulating layer 9 may be the same as or different from that of the first insulating layer 3, and may be selected according to actual conditions.

the first heat preservation layer 3 is filled between the wall penetrating pipe 1 and the wall penetrating sleeve 2;
and the supporting structure 4 is arranged at a pipe orifice at one end of the wall bushing 2, one end of the supporting structure 4 is connected with the pipe orifice at one end of the wall bushing 2, and the opposite end of the supporting structure (4) extends towards the direction of the wall bushing 1 and is not contacted with the outer wall of the wall bushing 1.
The through-wall opening structure is used for through-wall opening nodes of a wall body during construction, so that the operation process of arranging structures such as through-wall pipes in the wall body by a conventional construction method is omitted, the construction process is simplified, and the construction efficiency is improved; meanwhile, the production process of the structure is independent of the construction process of the wall body, and standardized production can be carried out in advance in a factory, so that the quality can be effectively controlled, and each produced structure is guaranteed to have good air tightness and a heat bridge breaking effect.
Furthermore, the wall-through opening structure further comprises a waterproof and vapor-permeable membrane 5 which is arranged at the pipe orifice at one end of the wall-through sleeve 2 and partially covers the supporting structure 4 and the outer wall of the wall-through pipe 1 so as to seal the pipe orifice. The through-wall opening structure is used for the through-wall opening node of the wall body, and the waterproof and breathable film 5 can be prevented from being paved in the construction process, so that the construction time is shortened, and the construction efficiency is improved. The supporting structure 4 in this embodiment is used to facilitate the application of the waterproof and breathable film 5.
It will be appreciated that the waterproof and vapor permeable membrane 5 partially covering the support structure 4 is not bondable to the outer wall of the wall bushing 2, the bonding of the outer wall of the wall bushing 2 affecting the contact of the wall bushing 2 with the concrete layer 8 provided at its periphery, so that the air tightness and thermal bridge cut-off effect at this location are affected.

The length of the support structure 4 is related to the degree of adhesion stability of the waterproof and vapor-permeable membrane 5. When the supporting structure 4 is short, the sticking area of the waterproof and breathable film 5 on the supporting structure 4 is low, so that the sticking of the waterproof and breathable film 5 is inconvenient, and the sticking effect cannot be ensured, thereby having adverse effects on the air tightness and the heat bridge cutoff effect at the through-wall hole node of the wall body; therefore, the proper length of the supporting structure 4 is not only beneficial to the adhesion of the waterproof and breathable film 5, but also ensures the adhesion effect.
Further, the thickness of the first heat-insulating layer 3 is 3cm to 20 cm. The thickness is also the size of the gap between the wall bushing 1 and the wall bushing 2. When the thickness is small, it is difficult to fill the first heat-insulating material between the wall-penetrating pipe 1 and the wall-penetrating sleeve 2, and the heat-insulating effect is affected due to the insufficient uniform and compact filling and insufficient thickness; when the thickness is large, the cost is high, and the waste of the first heat insulating material is also caused.

Specifically, the first heat-insulating layer 3 is made of heat-insulating cotton, rock wool felt or polyurethane special for pipelines. It should be understood that other materials with good thermal insulation effect are also within the scope of the present application. The material of the through-wall pipe 1 includes but is not limited to PVC pipe or PP pipe; the material of the wall bushing 2 includes but is not limited to PVC pipe or PP pipe.
