Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a frame and leaf structure of an aluminum-plastic composite door and window with ultra-low energy consumption. Background Art
[0002] The construction industry is increasingly concerned about energy consumption. Aluminum-plastic composite doors and windows, with their excellent thermal insulation properties, help reduce building energy consumption and meet the requirements of sustainable development. Aluminum-plastic composite doors and windows are a composite of aluminum alloy and plastic (typically polyvinyl chloride (PVC)). Their structure typically consists of an aluminum alloy exterior filled or coated with plastic, forming a composite structure. Aluminum alloy inherently has strong thermal conductivity, while plastic has weak thermal conductivity. This composite structure effectively reduces heat conduction, improves the thermal insulation performance of doors and windows, and reduces energy consumption.
[0003] Existing aluminum-plastic composite doors and windows typically utilize a direct fixing method, where the aluminum alloy back panel and plastic frame are directly fixed together using glue or bolts. This method is relatively simple and cost-effective to manufacture, but it also has some disadvantages. Due to different thermal expansion coefficients, fatigue stress may occur in the joints of the doors and windows, causing the glue or bolts to loosen and fall off, thereby affecting the durability and waterproof performance of the doors and windows. Utility Model Content
[0004] In view of this, the utility model provides a frame and sash structure of an aluminum-plastic composite door and window with ultra-low energy consumption, which can solve the problem that the joints of the existing aluminum-plastic composite doors and windows are easily affected by thermal expansion and contraction and thus fall off.
[0005] The utility model is achieved in this way:
[0006] The utility model provides a frame-sash structure of an ultra-low energy consumption aluminum-plastic composite door and window, which includes thermal insulation glass, a first outer frame, a second outer frame, a plurality of first composite adhesive strips, a second composite adhesive strip, a pressure line, a plastic profile and a frame profile. The outer side of the thermal insulation glass is fixedly connected to the upper end of the first outer frame through the first composite adhesive strip, the lower end of the first outer frame is fixedly connected to the upper end of the second outer frame through the first composite adhesive strip, the inner side of the thermal insulation glass is fixedly connected to the pressure line through the first composite adhesive strip, the lower end of the pressure line is slidably installed and connected to the upper end of the frame profile, the lower end of the frame profile is fixedly connected to the plastic profile through the first composite adhesive strip, the frame profile is connected to the first outer frame by a buckle, the second outer frame is connected to the plastic profile by the buckle, and the plastic profile is fixedly connected to the frame profile by the second composite adhesive strip.
[0007] The technical effects of the frame and sash structure of an ultra-low energy consumption aluminum-plastic composite door and window provided by this utility model are as follows: This new window sash design combines the advantages of aluminum and plastic, achieving an optimal balance between cost-effectiveness and performance. Its main benefits are as follows:
[0008] (1) Compared with all-aluminum window sashes, the use of plastic as the inner layer material significantly reduces production costs. The price of plastic itself is lower than that of aluminum, which makes this window sash more competitive in the market and can benefit more consumers.
[0009] (2) The aluminum material on the exterior surface is extremely weather-resistant and corrosion-resistant, and can effectively resist erosion from harsh environments such as wind, rain, sun, rain, and acid rain. This allows the windows to maintain their good appearance and function for a long time, extending their service life and reducing maintenance costs.
[0010] (3) Aluminum surface treatment technology is mature, with rich color options, which can be coordinated with various architectural styles. It can be sprayed with various colors and even surface treated, such as anodizing or powder coating, to enhance its corrosion resistance and decorative properties.
[0011] (4) The strength and hardness of the outer aluminum are much higher than those of the inner plastic, and it can effectively resist external impact, which enhances the overall safety and anti-destruction ability of the window and reduces the economic losses caused by accidental damage.
[0012] (5) The outer aluminum layer has strong thermal conductivity but poor thermal insulation performance, while the plastic inner layer makes up for this shortcoming. Its excellent thermal insulation performance effectively reduces heat conduction and improves the indoor thermal insulation performance.
[0013] (6) Aluminum and plastic have significantly different coefficients of thermal expansion. Direct connection can easily cause stress concentration, leading to cracking or deformation. This design cleverly uses a snap-on connection to allow for a certain amount of deformation between the two, effectively solving the problem of thermal expansion and contraction and ensuring the stability and durability of the window sash.
[0014] On the basis of the above technical solution, the frame and sash structure of the ultra-low energy consumption aluminum-plastic composite door and window of the present invention can also be improved as follows:
[0015] Among them, the buckle includes a fixing part, a supporting part, a connecting part and a through hole. The supporting part is fixedly connected at the midpoint of the lower bottom surface of the fixing part, the connecting part is fixedly connected on the side wall of the fixing part, and the through hole runs through the fixing part and the supporting part.
[0016] Furthermore, the fixing portion is a circular structure, the supporting portion is a rectangular structure, the connecting portion is an isosceles triangle structure, and the upper top surface of the connecting portion is flush with the upper top surface of the fixing portion.
[0017] Furthermore, the altitude of the isosceles triangle of the connecting portion is perpendicular to the long side of the supporting portion.
[0018] Furthermore, the molding profile and the frame profile are both provided with galvanized steel linings, a plurality of plastic-steel cavities are provided on the periphery of the galvanized steel linings, and the thickness of the galvanized steel linings is 1.5 mm.
[0019] Furthermore, the number of the plastic-steel cavities of the frame profile is six, and the number of the plastic-steel cavities of the plastic profile is ten.
[0020] The benefits of this improved solution include: the multi-chamber design effectively isolates the temperature difference between the outside environment and the interior, reducing heat conduction. Each chamber acts as an insulating layer, slowing the loss of heat through the window frame and the transfer of heat from the outside into the room. Therefore, multi-chamber profiles significantly improve the window's thermal insulation performance, effectively maintaining a stable indoor temperature.
[0021] Furthermore, the molding profile, the frame profile and the pressing wire are all made of plastic, and the first outer frame and the second outer frame are both made of aluminum.
[0022] Furthermore, the first composite rubber strip and the second composite rubber strip are both made of EPDM automotive grade rubber.
[0023] The beneficial effects of adopting the above-mentioned improvement scheme are: the composite isobaric strip can effectively fill the gap between the frame and the frame sash, and prevent the entry of external factors such as air, moisture and dust to the greatest extent, thereby improving the overall sealing performance of doors and windows.
[0024] Furthermore, the second composite rubber strip is a foamed structure.
[0025] The beneficial effect of adopting the above-mentioned improvement scheme is that the second composite rubber strip is sloped and can discharge water that accidentally enters the interior of the second outer frame along the slope.
[0026] Furthermore, a drain outlet is provided on the second outer frame, and the drain outlet is used to drain the accumulated water entering the second outer frame.
[0027] Compared with the existing technology, the beneficial effects of the ultra-low energy consumption aluminum-plastic composite door and window frame and sash structure provided by the utility model are: this new window sash design combines the advantages of aluminum and plastic, achieving an optimal balance between cost-effectiveness and performance. Its main benefits are as follows:
[0028] (1) Compared with all-aluminum window sashes, the use of plastic as the inner layer material significantly reduces production costs. The price of plastic itself is lower than that of aluminum, which makes this window sash more competitive in the market and can benefit more consumers.
[0029] (2) The aluminum material on the exterior surface is extremely weather-resistant and corrosion-resistant, and can effectively resist erosion from harsh environments such as wind, rain, sun, rain, and acid rain. This allows the windows to maintain their good appearance and function for a long time, extending their service life and reducing maintenance costs.
[0030] (3) Aluminum surface treatment technology is mature, with rich color options, which can be coordinated with various architectural styles. It can be sprayed with various colors and even surface treated, such as anodizing or powder coating, to enhance its corrosion resistance and decorative properties.
[0031] (4) The strength and hardness of the outer aluminum are much higher than those of the inner plastic, and it can effectively resist external impact, which enhances the overall safety and anti-destruction ability of the window and reduces the economic losses caused by accidental damage.
[0032] (5) The outer aluminum layer has strong thermal conductivity but poor thermal insulation performance, while the plastic inner layer makes up for this shortcoming. Its excellent thermal insulation performance effectively reduces heat conduction and improves the indoor thermal insulation performance.
[0033] (6) Aluminum and plastic have significantly different coefficients of thermal expansion. Direct connection can easily cause stress concentration, leading to cracking or deformation. This design cleverly uses a snap-on connection to allow for a certain amount of deformation between the two, effectively solving the problem of thermal expansion and contraction and ensuring the stability and durability of the window sash.

[0042] The thermal insulation glass 10 adopts triple-glass, double-cavity, double-pane, double-silver low-e thermal insulation glass with a K value of less than 0.75w / kh;
[0043] The K value represents the heat transfer coefficient of the window. The smaller the value, the better the thermal insulation performance of the window and the slower the heat loss through the window.

[0046] Two-chamber: refers to the two cavities filled with dry air between the three layers of glass. The air in the cavity is evacuated and filled with inert gas (which can further improve the thermal insulation effect).
[0047] Double Silver Low-E: refers to low-emissivity coated glass. "Double Silver" means that both pieces of Low-E glass are coated with a low-emissivity film. "Double Silver" has a better thermal insulation effect than single silver Low-E glass.
[0048] Among them, in the above technical solution, the buckle 20 includes a fixing part 201, a supporting part 202, a connecting part 203 and a through hole 204. The supporting part 202 is fixedly connected at the midpoint of the lower bottom surface of the fixing part 201, the connecting part 203 is fixedly connected on the side wall of the fixing part 201, and the through hole 204 passes through the fixing part 201 and the supporting part 202.
[0049] Furthermore, in the above technical solution, the fixing portion 201 is a circular structure, the supporting portion 202 is a rectangular structure, the connecting portion 203 is an isosceles triangle structure, and the upper top surface of the connecting portion 203 is flush with the upper top surface of the fixing portion 201 .
[0050] Furthermore, in the above technical solution, the altitude of the isosceles triangle of the connecting portion 203 is perpendicular to the long side of the supporting portion 202 .
[0051] Furthermore, in the above technical solution, galvanized steel linings 19 are provided inside the molding profile 16 and the frame profile 17, and multiple plastic-steel cavities 18 are provided on the periphery of the galvanized steel lining 19. The thickness of the galvanized steel lining 19 is 1.5 mm.
[0052] Furthermore, in the above technical solution, the number of the plastic-steel cavities 18 of the frame profile 17 is six, and the number of the plastic-steel cavities 18 of the plastic profile 16 is ten.
[0053] Furthermore, in the above technical solution, the molding profile 16, the frame profile 17 and the pressing wire 15 are all made of plastic, and the first outer frame 11 and the second outer frame 12 are both made of aluminum.

[0057] When using the clip 20 for connection, first align the top surface of the fixing portion 201 with the profile, and then insert the rotating pin through the through hole 204 to install the entire clip 20 on the profile. At this time, the first outer frame 11 and the second outer frame 12 are buckled onto the support portion 202. The size of the slot opening between the first outer frame 11 and the second outer frame 12 is compatible with the size of the short side of the support portion 202. Therefore, the support portion 202 passes through the slot of the first outer frame 11 and the second outer frame 12 and goes deep into the slot. Pinch the connecting portion 203 and rotate it 90 degrees. At this time, the fixing portion 201 and the support portion 202 also rotate around the rotating pin until the long side of the support portion 202 is stuck in the slot. At this time, the first outer frame 11 and the second outer frame 12 are fixed. Due to the different thermal expansion coefficients of aluminum and plastic, deformation will occur at the connection, and there is a margin of movement between the clip and the slot.
[0058] Specifically, the principle of the present invention is as follows: when using the buckle 20 for connection, first fit the upper surface of the fixing portion 201 to the profile, and then insert the rotating pin through the through hole 204 to install the entire buckle 20 on the profile. At this time, the first outer frame 11 and the second outer frame 12 are buckled onto the support portion 202. The size of the slot opening between the first outer frame 11 and the second outer frame 12 is adapted to the size of the short side of the support portion 202. Therefore, the support portion 202 passes through the slot of the first outer frame 11 and the second outer frame 12 and goes deep into the slot. Pinch the connecting portion 203 and rotate it 90 degrees. At this time, the fixing portion 201 and the support portion 202 also rotate around the rotating pin until the long side of the support portion 202 is stuck in the slot. At this time, the first outer frame 11 and the second outer frame 12 are fixed. Due to the different thermal expansion coefficients of aluminum and plastic, deformation will occur at the connection, and there is a margin of movement between the buckle and the slot.
