Technical Field

[0001] The present invention relates to the technical field of ultra-low energy consumption building construction, and particularly to a plugging structure and construction method for a louver opening on the airtight layer of an ultra-low energy consumption building. Background Art

[0002] Compared with traditional buildings, higher requirements are put forward for the construction standards and technical difficulties of ultra-low energy consumption buildings. Especially when dealing with the combination of openings penetrating the peripheral enclosure structure and passive door and window units, how to ensure key indicators such as the overall airtightness and thermal performance of the building has become a major problem that needs to be solved urgently during the construction process. In the current construction of ultra-low energy consumption buildings, the conventional practice in drawing design is to open holes in the exterior wall and plug them according to relevant nodes.

[0003] In order to solve the construction method problem of the exhaust fan pipe openings of the power distribution room and weak current room on the first floor penetrating the passive window in the kindergarten project of the urban village renovation in the main urban area of Baoding City, through the investigation summary and innovative upgrade of various construction methods for plugging openings penetrating the enclosure structure, this project has summarized a construction plugging method for louver openings on the airtight layer of an ultra-low energy consumption building. Summary of the Invention

[0004] The main purpose of the present invention is that when equipment pipelines penetrate a passive door and window unit, the originally designed passive area boundary line on the drawing is moved towards the indoor direction to the inner partition wall adjacent to the passive door and window unit, so as to ensure the key indicators such as the overall airtightness and thermal performance of the passive building without changing the space use function.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a plugging structure for a louver opening on the airtight layer of an ultra-low energy consumption building, including a passive door and window unit, louver opening glass, and an inner partition wall. The louver opening glass is arranged on the passive door and window unit. The passive door and window unit is located on one side of the inner partition wall. Both the inner and outer sides of the inner partition wall are plastered with inorganic lightweight aggregate thermal insulation mortar, and silicone sealant is provided at the profile closing of the inner partition wall and the passive door and window unit.

[0006] Preferably, an equipment pipeline is arranged inside the louver opening glass. The equipment pipeline penetrates through the inner partition wall. A thermal insulation layer is arranged on the outer side wall of the equipment pipeline, and rock wool is arranged between the inner partition wall and the equipment pipeline.

[0007] Preferably, a waterproof and vapor barrier film and a waterproof and vapor permeable film are respectively adhered to the contact positions of the equipment pipeline with the inner and outer side walls of the inner partition wall.

[0008] Preferably, the equipment pipeline includes a fresh air equipment pipeline or a line passing through the passive door and window unit.

[0009] Preferably, a rainproof louver is installed outside the louver opening glass.

[0010] Preferably, cement mortar is applied between the internal partition wall and the inorganic light aggregate thermal insulation mortar, and an alkali-resistant fiberglass mesh cloth is arranged on the outer surface of the inorganic light aggregate thermal insulation mortar.

[0011] Preferably, the thickness of the inorganic light aggregate corrugated mortar is 30 mm, and the alkali-resistant fiberglass mesh cloth is embedded in the surface of the inorganic light aggregate corrugated mortar.

[0012] Preferably, the closing part of the internal partition wall is arranged inside the profile of the passive door and window.

[0013] Preferably, the gap between the passive door and window and the internal partition wall is filled with fireproof rock wool. The passive door and window includes a profile and tempered insulating glass, and an aluminum single board for shielding the fireproof rock wool is arranged between the profile and the internal partition wall.

[0014] A construction method for a plugging structure of a louver opening on the airtight layer of an ultra-low energy consumption building includes the following steps: Step 1, thermal insulation construction of the internal partition walls in the passive area and the non-passive area. The construction personnel first measure and position the range of the internal partition walls to be constructed and determine the positions of the equipment pipelines. The thermal insulation construction process of the internal partition walls on the changed passive area boundary line is to brush a layer of building glue and neat cement slurry with a glue ratio of 1:4, then carry out leveling and roughing with 10-mm-thick 1:3 cement mortar, then apply 30-mm-thick inorganic light aggregate thermal insulation mortar and press the alkali-resistant fiberglass mesh cloth, and finally carry out the construction of a 5-mm-thick 1:1 cement mortar with 20% of the water weight of building glue or the special tile adhesive used in combination. Step 2, first install the passive door and window frame, and lay out in advance the actual positions of the equipment pipelines passing through the passive door and window openings to facilitate the processing of the cut special-shaped glass. Step 3, fixing the passive door and window to the internal partition wall. When there is a gap between the passive door and window and the internal partition wall, fireproof rock wool is used for plugging, and a 2.0-mm-thick same-color aluminum single board is used as a back lining board on the back side of the passive door and window, that is, the indoor side, for shielding to prevent the rock wool board or the internal partition wall from being seen from the outside of the passive door and window. Step 4, plugging of the equipment pipelines passing through the internal partition wall. At the positions where the equipment pipelines pass through the internal partition wall, at the intersection parts of the pipelines and the wall on both the indoor and outdoor sides, waterproof vapor barrier membranes and waterproof breathable membranes are respectively pasted. The contact part between the equipment pipelines and the internal partition wall is filled tightly with 50-mm-thick rock wool, and finally the intersection part between the outdoor equipment pipelines and the internal partition wall is integrally sealed with sealant. Step 5, installing the special-shaped louver opening glass, and integrally sealing the intersection part between the equipment pipelines and the special-shaped louver opening glass with sealant.

[0015] The present invention provides an ultra-low energy consumption building airtight layer louver opening plugging structure and a construction method, which have the following beneficial effects.

[0016] 1. In the present invention, by moving the passive area boundary line to the internal partition wall, the sealing of the internal partition wall is carried out according to the schematic diagram of the node practice for equipment pipelines passing through the partition wall, enhancing the sealing performance at the location where the equipment pipeline passes through the passive French door and window, and avoiding airtightness damage caused by the crossing of equipment pipelines.

[0017] 2. Ultra-low energy consumption buildings emphasize the insulation and heat insulation performance of the building. Moving the passive area boundary line to the internal partition wall helps reduce heat transfer through the crossing points of equipment pipelines. This can ensure that the building's energy consumption remains at a low level, meeting the design requirements of ultra-low energy consumption buildings.

[0018] 3. This construction method does not require large-scale adjustment of the original space layout, only local treatment is needed at the crossing points of equipment pipelines. Therefore, it can improve the airtightness and thermal performance without affecting the building's usage function.

[0019] 4. Compared with complex sealing treatment on the passive French door and window, moving the passive area boundary line to the internal partition wall is usually easier to achieve. This helps reduce the construction difficulty and cost, while improving the construction efficiency.

[0020] 5. Through this construction method, it can ensure that the overall performance of the passive building is maintained and improved. This helps extend the building's service life, reduce energy consumption and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0028] As Figure 1-6 shown, the present invention provides a plugging structure for louver openings on the airtight layer of an ultra-low energy consumption building.

[0029] Embodiment 1 The main purpose of the present invention is that when equipment pipelines pass through the passive door and window, the originally designed passive area boundary line on the drawing is moved towards the indoor direction to the interior partition wall adjacent to the passive door and window, which can not only not change the space use function but also ensure the key indicators such as the overall airtightness and thermal performance of the passive building.

[0030] To achieve the above purpose, the technical solution adopted by the present invention is as follows: The construction plugging structure for louver openings on the airtight layer of an ultra-low energy consumption building, as Figures 2-6 shown, includes a passive door and window 1, glass for louver opening 2, interior partition wall 3, inorganic light-aggregate thermal insulation mortar 4 and silicone sealant 5, and is characterized in that: the glass for louver opening 2 is on the passive door and window 1, the passive door and window 1 is adjacent to the interior partition wall 3, inorganic light-aggregate thermal insulation mortar 4 is plastered on both the inner and outer sides of the interior partition wall 3, and the joint of the interior partition wall 3 at the profile of the passive door and window 1 is sealed with silicone sealant 5.

[0031] The joint of the interior partition wall 3 at the profile of the passive door and window 1 is sealed with silicone sealant 5. The silicone sealant 5 has good sealing performance and weather resistance, can effectively fill the gaps at the joint, prevent the penetration of air and moisture, and ensure the integrity of the airtight layer. At the same time, the use of silicone sealant 5 can also enhance the connection strength between the interior partition wall 3 and the passive door and window 1, and improve the stability of the entire plugging structure.

[0032] The plugging structure includes: a special-shaped glass for louver opening 2 that conforms to the equipment pipeline is installed on the first passive door and window 1; cement mortar 501 and inorganic light-aggregate thermal insulation mortar 4 are respectively applied on both sides of the second interior partition wall 3; the equipment pipeline 404 passes through the interior partition wall 3 with a waterproof and breathable membrane 401, rock wool 402, a waterproof and vapor barrier membrane 405 and silicone sealant 5.

[0033] The louvered opening glass 2 is installed on the passive French door with window 1, and the first sealing structure is to install the special-shaped louvered opening glass 2 that conforms to the equipment pipeline on the passive French door with window 1. The passive French door with window 1 is located on the passive area boundary line. Due to space usage requirements or force majeure factors, openings must be reserved for exterior doors and windows. At this time, the setting of the special-shaped louvered opening glass 2 can not only meet the needs of equipment pipelines (such as fresh air equipment pipelines or other pipelines or lines) passing through, but also ensure the integrity and aesthetics of the doors and windows. At the same time, the passive French door with window 1 itself has good heat preservation and airtight performance, which can effectively reduce the heat exchange between indoors and outdoors and improve the energy-saving effect of the building. The combined installation of the louvered opening glass 2 and the passive French door with window 1 further enhances the sealing performance of this area, prevents air infiltration, and reduces energy consumption.

[0034] The passive French door with window 1 is adjacent to the internal partition wall 3. On both the inner and outer sides of the internal partition wall 3, inorganic lightweight aggregate thermal insulation mortar 4 with a thickness of 30 mm is plastered, and alkali-resistant fiberglass mesh cloth 503 is pressed in and the construction is completed before the installation of the passive French door with window 1. On both sides of the internal partition wall 3, cement mortar 501 and inorganic lightweight aggregate thermal insulation mortar 4 are respectively used as the second sealing structure. The inorganic lightweight aggregate thermal insulation mortar 4 has the characteristics of being lightweight and having good heat insulation performance, which can effectively reduce the heat transfer of the internal partition wall 3 part and improve the heat preservation performance of the building. Pressing in the alkali-resistant fiberglass mesh cloth 503 can enhance the crack resistance of the thermal insulation layer, prevent cracks from appearing in the thermal insulation layer, and thus ensure the durability of the heat preservation effect. The internal partition wall 3 is adjacent to the passive French door with window 1. For low floors (1 - 3 floors), to ensure the aesthetics of the building effect, the closing of the internal partition wall 3 must be at the profile of the passive French door with window 1. Such a design makes the building appearance more neat and beautiful, and is also convenient for construction operation and quality control.

[0035] The third sealing structure is that when the equipment pipeline 404 passes through the internal partition wall 3, a waterproof breathable film 401, rock wool 402, a waterproof vapor barrier film 405 and silicone sealant 5 are used for sealing. When the equipment pipeline 404 passes through the internal partition wall 3, at the intersection of the pipeline and the wall on both the indoor and outdoor sides, a waterproof vapor barrier film 405 and a waterproof breathable film 401 are respectively pasted. The contact part between the equipment pipeline 404 and the internal partition wall 3 is filled densely with 50-mm-thick rock wool 402. Finally, the intersection part between the outdoor equipment pipeline 404 and the internal partition wall 3 is integrally sealed with silicone sealant 5. The waterproof vapor barrier film 405 can prevent the water vapor indoors from penetrating into the thermal insulation layer and avoid the thermal insulation layer getting damp and reducing the thermal insulation performance; the waterproof breathable film 401 allows the water vapor to be discharged from the indoor side while preventing the outside moisture from entering and keeping the thermal insulation layer dry. The rock wool 402 has good heat preservation and fireproof performance. Filled in the contact part between the equipment pipeline and the internal partition wall, it can not only play a heat preservation role but also prevent the spread of fire. The use of silicone sealant 5 further enhances the sealing effect, ensures the airtightness of the part where the equipment pipeline passes through, and prevents air leakage and heat loss.

[0036] Construction method for plugging structure of louver opening on airtight layer of ultra-low energy consumption building, including the following steps: Step 1: Thermal insulation construction of internal partition wall 3 in passive area and non-passive area As Figure 1 shown, construction workers first measure and locate the scope of internal partition wall 3 to be constructed and determine the position of equipment pipeline 404; As Figure 5 shown, thermal insulation construction technology of internal partition wall 3 on the changed passive area boundary line 101: brush a layer of building glue neat cement slurry, glue ratio is 1:4 → 10 mm thick 1:3 cement mortar 501 for leveling and rubbing to make rough → 30 mm thick inorganic lightweight aggregate thermal insulation mortar 4 and press alkali-resistant fiberglass mesh cloth 502 → 5 mm thick 1:1 cement mortar with 20% building glue (or supporting special tile adhesive) binder layer; Step 2: Install the frame of passive door and window 1 First install the frame of passive door and window 1, which can facilitate early lofting of the actual position of equipment pipeline 404 passing through the opening of passive door and window 1, so as to process the special-shaped glass with cutouts; Step 3: Fixation of passive door and window to internal partition wall As Figure 6 shown, there is a gap between passive door and window 1 and internal partition wall 3, and fireproof rock wool 402 is used for plugging. To avoid seeing the rock wool board 402 or internal partition wall 3 on the outside of passive door and window 1, a 2.0 mm same-color aluminum single board is used as a backing board on the back (indoor side) of passive door and window 1 for shielding.

[0037] Step 4: Plugging of equipment pipeline 404 passing through internal partition wall 3 As Figure 4 shown, at the position where equipment pipeline 404 passes through internal partition wall 3, at the intersection of indoor and outdoor pipelines and the wall, waterproof vapor barrier film 405 and waterproof breathable film 401 are respectively pasted. The contact part between equipment pipeline 404 and internal partition wall 3 is filled tightly with 50 mm thick rock wool 402, and finally the intersection part of outdoor equipment pipeline 404 and internal partition wall 3 is integrally sealed with sealant 5.

[0038] Step 5: Install special-shaped louver opening glass 2 As Figure 2 and Figure 3 shown, install special-shaped louver opening glass 2, and the intersection part between equipment pipeline 404 and special-shaped louver opening glass 2 is integrally sealed with sealant 5. Thus, the construction plugging of the louver opening on the airtight layer of the ultra-low energy consumption building is completed.
