Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, and in particular to an aluminum alloy passive window structure and a construction method. Background Art

[0002] Within the building envelope, exterior windows, exterior walls, roof, and floors are the four major components of building energy consumption. Energy lost through doors and windows accounts for approximately 40% to 50% of the total energy consumption of the building envelope. This shows that doors and windows are key to building energy conservation. Therefore, reducing the energy consumption of exterior windows in passive ultra-low energy buildings and improving the thermal insulation performance of passive windows are crucial for maintaining a healthy indoor environment and energy efficiency.

[0003] However, existing passive windows have relatively poor thermal insulation and waterproof effects, and are prone to defects such as water leakage, air leakage, and cold weather that affect the energy-saving effect of buildings. The existing insulation construction methods around passive windows and doors are complicated, making the construction process very difficult and difficult to ensure the structural strength and construction efficiency of passive windows.

[0019] like Figures 1 to 5As shown, an aluminum alloy passive window structure includes a window frame body and glass 1. The window frame body includes a sash frame 2 and a frame 3 connected to each other. A waterproof vapor barrier membrane 9 is provided on the airtight layer 10 of the outdoor wall on the side of the frame 3 located outdoors. A window sill 11 is provided on the waterproof vapor barrier membrane 9. A vacuum insulation panel 12 is provided on the indoor wall. The frame 3 is connected to the wall through a connecting piece. Glass 1 is provided on the sash frame 2. A drip edge 201 is provided at the bottom of the sash frame 2 located outdoors. The drip edge 201 is connected to the frame 3. Water retaining ribs 301 are provided on the side of the frame 3 located outdoors. The water retaining ribs 301 are located below the drip edge 201. Two insulation strips 7 are provided in the sash frame 2 and the frame 3. An insulation cavity is formed between the two insulation strips 7 of the sash frame 2 or the frame 3. Insulation fillers 8 are provided at the connection between the end of the glass 1 and the sash frame 2 and in the insulation cavity. Water-retaining ribs 301 are designed to ensure the drainage capacity of doors and windows; drip edges 201 are designed to prevent rainwater from flowing inward from the profile surface. The insulation strips 7 are dense-foamed soft and hard co-extruded rubber strips, with overlapping foam strips to increase the overlap area and improve sealing performance. The multi-cavity design of the insulation cavity reduces heat convection and radiation, lowering the K value of doors and windows. Due to the convection characteristics of heat transfer, convection is easily generated in larger cavities in the profile structure, causing heat loss. Therefore, the insulation cavity is filled with insulation filler 8, which is an internal polyurethane foam material to ensure that no heat is lost in this area. Low-e glass 1 is used for glass 1; 6+16Ar+6+16Ar+6 Low-E insulating glass 1 is selected to reduce the surface emissivity of glass 1, reduce radiant heat transfer, increase thermal resistance, and reduce the heat transfer coefficient of insulating glass 1. This improves the insulation performance by 50% compared to ordinary insulating glass 1, achieving excellent energy-saving effects.

[0020] The sash frame 2 and the frame 3 are connected by a rubber strip assembly, which includes a first rubber strip 4, a second rubber strip 5, and a third rubber strip 6. The first rubber strip 4 is positioned at the junction of the drip edge 201 and the frame 3. The second rubber strip 5 is positioned between the insulation strip 7 in the middle of the sash frame 2 and the frame 3. The third rubber strip 6 is positioned at the junction of the bottom end of the sash frame 2 away from the drip edge 201 and the frame 3. The doors and windows are designed with three seals, and the rubber strip assembly is made of EPDM, which has excellent aging resistance and will not crack or harden with use.

[0021] Fourth adhesive strips 13 are provided at the connection points between the two sides of the glass 1 and the sash frame 2 .

[0022] The connecting piece includes a heat-insulating gasket 14 and a connecting bolt 15 . The heat-insulating gasket 14 is provided between the frame 3 and the wall, and is fixedly connected to the wall via the connecting bolt 15 .

[0023] A construction method for an aluminum alloy passive window, applicable to any of the above-mentioned aluminum alloy passive window structures, comprises the following steps: Step 1: Mark the lines and pre-install the fixed corner pieces and antiseptic wood. Step 2: Adjust and fix the window frame on the wall. The window frame should be deep and the indoor surface of the window frame should be flush with the outdoor surface of the wall. When installing, it should be installed horizontally and vertically in the center. The installation tolerance table should comply with the installation allowable deviation table in Table 1. Table 1 Passive window installation allowable deviation table, unit: mm After the entire window is adjusted, the corner pieces and window frames are connected and fixed using 4.2*40 pan-head galvanized self-tapping screws.

[0024] Step 3: Paste the waterproof vapor barrier film 9 indoors and outdoors. Step 4: Install glass 1. Before installing glass 1, clean the mortar and debris from the slots to ensure a clear drainage system. When installing glass 1, properly place load-bearing and positioning blocks to prevent it from sliding within the frame slot and maintain frame alignment to ensure proper function. The blocks should be located approximately 100mm from the sides of the glass 1. The materials used must not affect the flow of water or air within the frame slot. To install the glass 1 gasket, first install the bottom glass 1 gasket, then position the glass 1, and finally the left, right, and top glass 1 gaskets. Mark glass 1 with a 3C mark and install it in the lower right corner of the room. For smaller glass 1 sizes, use two hands to secure it in place. Larger glass 1 sizes can be installed using a glass suction cup. Glass 1 does not bear any force, and any edge of the glass 1 must not come into direct contact with the aluminum alloy profile or screws to prevent shattering. The sealing strips used to secure the glass 1 should be flat, smooth, tight, and secure to prevent water seepage.

[0025] Step 5: Install the passive window sash. The installation of the passive window sash should be carried out when the wet work of the civil engineering project is basically completed to keep the doors and windows intact. During installation, first install the hinges and fix them to the window frame according to the design positioning, then embed the window sash into the frame and temporarily fix it, adjusting it to fit. After fixing the window sash to the hinge and ensuring that the center axis of the upper and lower hinges are vertically aligned, you can stop it at will when closing the window.

[0026] Step 6: Apply glue around the glass. Step 7: Base treatment: First, fill the seams, then lay the alkali-resistant mesh cloth, and finally carry out the exterior finishing construction. Step 8. Install the window sill 11. Pre-compression expansion tape should be pasted at both ends and the connection with the insulation to prevent water from entering and damaging the insulation layer; the slope of the window sill is ≥6%; it is determined according to different regions; the pre-compression expansion tape is pasted on the lower side of the window sill 11 to achieve airtightness with the lower insulation; the degree exceeds the finished surface by ≥40mm, and a drip line is set; the screws for fixing the window sill 11 should be stainless steel nails, and the stainless steel nails and the window sill 11 should be gasketed or glued.

[0027] Step 9: Apply sealant to the inner and outer walls around the doors and windows. After the finishing layer is completed, weather-resistant silicone sealant should be applied to the junction with the door and window frames. Pay attention to the following points when applying the sealant: the working surface to be applied should be cleaned before applying the sealant. It is strictly forbidden to have loose soil, grease, and foreign matter on the working surface. The glue surface should be even and flat without bubbles to avoid peeling or flanging after a period of time. Take good care of the exterior wall that has been applied. After the surface is cured, check again to see if there is any damage, omission, or looseness. Only proceed to the next step after it is intact. The sealant should be kept at a temperature of 5~40℃ and a relative humidity of 40~8 0% clean environment; it is difficult to construct when the surface temperature of the substrate exceeds 50℃, and it is also difficult to construct on the building surface exposed to direct sunlight. Since the sealant cannot be exposed to rain before curing, it is not easy to carry out outdoor construction on rainy days; the sealant has not been completely cured within 48 hours after construction, and the sealing joint is not allowed to have large displacement and the glue surface cannot be touched, otherwise it will affect the sealing effect and appearance; the width of the glue surface gap is ≥8mm; the glue surface should be uniform, smooth and flat, and no omissions or bubbles are allowed; the glue surface angle should be uniform, and the angle should be 45°.

[0028] In step 1, measure the distance between the mounting holes for the fixings and the edge of the opening, using a plumb line to draw the control line. Measure and mark the fixing positions, 150mm from the edge and with spacing ≤750mm. Install at least two fixings per side. Use an infrared level for corrections as necessary. Use 10x80mm expansion bolts to secure the corner fittings, with the pre-drilled holes 10mm deeper than the anchoring depth. Use 12x120mm expansion bolts to secure the preservative wood. For single window frames >600mm wide, install at least two brackets, ≤150mm from the edge. During installation, ensure the preservative wood is level, and cracking is not permitted. If required by the design, an insulation subframe can be used to secure the lower edge. When installing the insulation subframe, ensure the wall is free of particles, oil stains, and dust. Apply two coats of special glue on the side where the subframe contacts the wall. Use 7.5x132mm concrete screws for the subframe, ≤150mm from the end and ≤500mm apart. The minimum splicing length should be no less than 300mm. Ensure the subframe is level during installation.

[0029] In step 3, pre-paste indoors, the width of the waterproof vapor barrier film 9 and the frame should not be less than 15mm, and the paste should be tight without bulging; the reserved amount at the corner should be 1.5 times the gap between the window frame and the structure, and not less than 10mm; the interface should be on the side, using the upper pressure and lower overlap method, and the overlap amount should not be less than 100mm; the corners should be folded and pasted with masking paper to prevent scratches during installation, and it should not be too tight when pasting, and there should be no hollowing or missing. The width of the waterproof vapor barrier film and the structure should not be less than 15mm. The width of the waterproof vapor barrier membrane 9 bonded to the structure shall not be less than 50mm, and the glue shall be fully applied; for outdoor use, the order of pasting is: first paste the lower side, then paste the left and right sides, and finally paste the upper side; the width of the waterproof vapor barrier membrane 9 bonded to the structure shall not be less than 50mm, and the glue shall be tightly pasted without bulging; the width of the waterproof vapor barrier membrane 9 bonded to the window frame shall not be less than 15mm, and the glue shall be tightly pasted without bulging; the "patches" of corner fittings and antiseptic wood shall overlap with the large-surface waterproof breathable membrane, and the overlap width shall not be less than 50mm. Each side of the patch shall extend beyond the edge of the corner fitting by ≥30mm.

[0030] In step six, before applying the glue, use a rag to wipe away dust, powder, and other residues on the glued surface. After each cleaning, the glue application must be completed within 60 minutes, otherwise it should be cleaned again. When applying the glue, it is strictly forbidden for glass 1 to come into direct contact with the frame and sash material. The glue application must be uniform and continuous. After the glue application is completed, the glued surface must be repaired immediately and no more than 7 minutes are allowed. Repairs must be completed in one go and not repeated, otherwise there will be unevenness. The glue layer cures for 24 hours. The glued area must not be subjected to force or vibration within 12 hours, and contact with the glued surface is not allowed. The glue width should be 7-8mm and the thickness should be 4-5mm. The glue should be dense, uniform, smooth, and straight. The temperature during glue application is 4℃~40℃ and the relative humidity is 40%~80%. When applying the glue, maintain an appropriate speed to completely expel the air in the notch cavity to prevent cavitation and prevent bubbles from remaining in the glue seam. The glue application speed should be uniform and not fluctuate, keeping the glue seam full. After the glue application of a door or window is completed, the finished door and window and the sealant should be properly protected. The maintenance time must not be less than 21 days. Ensure that there is no collision with hard objects and no vibration of doors and windows within 21 days. The temperature of the maintenance environment should be between 18 and 28 degrees Celsius and the relative humidity should be around 70%.

[0031] In step seven, the cement mortar is locally leveled. During construction, horizontal and vertical reference lines are established. Then, according to the reference lines, lines are drawn on the wall to be pasted according to the facade layout design drawing, and the arrangement diagram of the insulation board is popped up; when filling the seams, the gaps between the boards are filled with insulation mortar. When filling the insulation mortar, do not use too much force to avoid damaging the vacuum board and causing air leakage. The mortar must be level with the surface of the insulation board to ensure a flat surface; when laying the alkali-resistant mesh cloth, apply the finishing mortar after the vacuum insulation board 12 is pasted; use a trowel to evenly apply the first coat of finishing mortar on the surface of the vacuum insulation board 12, and immediately press the alkali-resistant mesh cloth into the finishing mortar to cover the alkali-resistant mesh cloth and slightly see the outline. The mesh cloth should be flat and wrinkle-free, and the specification of the mesh cloth should be not less than 320g / m 2 , wait until the first coat of finishing mortar is slightly dry and hard enough to touch, then apply the second coat of anti-cracking mortar, so as to completely cover the alkali-resistant mesh cloth; first add additional mesh cloth 300mm long and 200mm wide at the four corners of the door and window openings in a 45° direction; after the finishing mortar and glass fiber mesh cloth are laid, they must not be moved and must be left to stand for curing for at least 24 hours before the next construction process can be carried out. In cold and humid climates, the curing time should be appropriately extended; cutting, bending, heavy object knocking and sharp object piercing are strictly prohibited during the construction of vacuum insulation panels 12; for exterior finishing construction, exterior finishing construction can be carried out seven days after the anti-cracking mortar layer has dried; exterior finishing surface construction should start from the top of the wall and proceed from top to bottom; the finishing layer around the doors and windows where it is connected to the thermal insulation board is thickened by 35mm, and the outermost finishing layer should extend 12mm beyond the outer frame surface of the doors and windows.

[0032] The on-site external installation of passive windows and their sealing technology ensures overall sealing performance after installation, meeting the requirements of passive ultra-low energy buildings. The use of vacuum insulation panels and their construction methods ensures the absence of thermal bridges between the passive windows and the exterior wall insulation, improving the overall sealing and thermal insulation of the building. Using thermally insulated aluminum alloy as the base material, through reasonable design and raw material selection, and efficient on-site installation and construction, the wind pressure resistance reaches level 9, the watertightness reaches level 6, the airtightness reaches level 8, and the thermal insulation performance K value is ≤0.8 W / (m²·K), improving the sealing and energy-saving effect by 20%.

[0033] Although the above describes the specific implementation methods of the invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
