Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a fixed frame glass structure of an aluminum-plastic composite door and window. Background Art

[0002] Aluminum-plastic composite doors and windows with fixed frame and glass combine the advantages of aluminum alloy and plastic materials. With the increasing emphasis on environmental protection and sustainable development in modern society, aluminum-plastic composite doors and windows are gaining increasing popularity in the market due to their eco-friendly materials and efficient energy-saving features. However, this aluminum-plastic composite structure also has certain drawbacks.

[0003] The difference in thermal expansion coefficients between aluminum alloy and plastic is one of the main causes of joint failure in aluminum-plastic composite doors and windows. Aluminum alloy has a significantly higher thermal expansion coefficient than plastic, meaning it expands and contracts much more rapidly under temperature fluctuations. This difference, over long periods of temperature fluctuation, can lead to significant stress accumulation, concentrated at the interface between the aluminum alloy and plastic. This is more than a simple material sealing issue; it involves complex issues in material mechanics and materials science. The fixed frame joints of traditional aluminum-plastic composite doors and windows are typically bonded or sealed with sealants to ensure airtightness and watertightness. However, due to the differential thermal expansion and contraction between aluminum alloy and plastic, the sealant is subjected to repeated tensile and compressive stress over time. This cyclical stress accelerates sealant aging, leading to a decrease in elasticity, cracking, and even delamination. Sealant failure directly reduces the sealing performance of doors and windows, causing air and water leaks, impacting indoor comfort and building energy efficiency. More seriously, failure of this joint can also affect the stability of the entire fixed frame.

[0004] In summary, the fixed frame glass structure of the existing aluminum-plastic composite doors and windows has the problem that the connection between the aluminum and plastic profiles is greatly affected by temperature changes, and is prone to unstable connections. Utility Model Content

[0005] In view of this, the utility model provides a fixed frame glass structure for aluminum-plastic composite doors and windows, which can solve the problem that the connection between aluminum and plastic profiles in the existing fixed frame glass structure of aluminum-plastic composite doors and windows is greatly affected by temperature changes and is prone to unstable connection.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a fixed frame glass structure of an aluminum-plastic composite door and window, which comprises glass, a composite adhesive strip, a pressure wire, an outer frame profile, a plastic-steel profile, an insulation plate, a drain outlet and a snap fitter. The outer side of the glass is fixedly connected to the outer frame profile via the composite adhesive strip, the inner side of the glass is fixedly connected to the pressure wire via another composite adhesive strip, a hook-shaped piece at the lower end of the pressure wire is slidably mounted in a groove at the top of the plastic-steel profile, the plastic-steel profile is arranged on the inner side of the outer frame profile, the plastic-steel profile and the outer frame profile are connected via the snap fitter, the outer frame profile is made of aluminum, and the plastic-steel profile is made of plastic.

[0008] The technical effects of the fixed frame glass structure of the aluminum-plastic composite door and window provided by the utility model are as follows: The composite door and window adopts a combined design of aluminum outer frame and plastic inner frame profile, which has the following advantages:

[0009] (1) The aluminum alloy outer frame has high strength and corrosion resistance, can withstand large external forces, and ensure the stability of doors and windows.

[0010] (2) The plastic inner frame itself has good thermal insulation performance, and the outer frame profile and the plastic steel profile are filled with insulation boards, which can effectively block heat transfer, reduce the temperature difference between indoor and outdoor, and save energy.

[0011] (3) The aluminum alloy outer frame can be surface treated, such as spraying, anodizing, etc., to give it a good appearance and corrosion resistance.

[0012] (4) The function of the insulation board is to further enhance the thermal insulation effect of doors and windows. It can form a thermal insulation barrier between the aluminum outer frame and the plastic inner frame, further reducing the heat exchange and thus improving the thermal insulation of doors and windows.

[0013] (5) Due to the presence of the aluminum outer frame, plastic inner frame and insulation board, this design can effectively isolate the conduction of external noise, thereby improving the sound insulation performance of doors and windows. This is especially useful in noisy areas in the city, and can provide a quieter environment indoors.

[0014] (6) The aluminum outer frame and the plastic inner frame are connected together by a snap-fit ​​device. This connection method not only improves the structural strength but also facilitates quick installation and removal. In addition, this snap-fit ​​method allows the different properties of the two materials to be optimally combined, ensuring a strong structure while facilitating the difference in thermal expansion coefficients between the different materials, thus avoiding the accumulation of stress in the materials due to temperature changes.

[0015] On the basis of the above technical solution, the fixed frame glass structure of the aluminum-plastic composite door and window of the present invention can also be improved as follows:

[0016] Among them, the outer frame profile includes an outer frame body and a snap-in groove, the outer side of the outer frame body is a flat structure, the snap-in groove is located in the middle of the inner side of the outer frame body, the snap-in groove includes a snap-in cavity and a snap-in interface, and the height of the snap-in interface is less than the height of the snap-in cavity.

[0017] Furthermore, the clamp includes a base, a connecting plate, a clamping block, a first through hole, a second through hole, a fixed shaft and a groove, the base is a square structure, the grooves are provided at the central axis of the four side walls of the base, the first through hole is provided on the upper top surface of the base, the first through hole is a rectangular structure, the midpoint of the first through hole coincides with the midpoint of the upper top surface of the base, the connecting plate is fixedly connected to the connecting block on both sides of the long side of the first through hole, the connecting plate is fixedly connected to the connecting block, the connecting block is a rectangular structure, the size of the connecting block is the same as the size of the first through hole, the second through hole is provided on the upper top surface of the connecting block, the second through hole is connected to the first through hole, the fixed shaft passes through the second through hole and the first through hole in sequence from top to bottom and is fixedly connected to the side walls of the plastic steel profile, and the fixed shaft is rotatably connected to the base and the clamping block.

[0018] Furthermore, the second through hole is a recessed structure with higher edges and lower center.

[0019] The beneficial effect of adopting the above-mentioned improved solution is that the second through hole is a recessed structure, which allows the fixed shaft to be inserted into the connecting plate as far as possible and hides the end of the fixed shaft.

[0020] Furthermore, the length of the long side of the card block is longer than the height of the card interface, the length of the short side of the card block is less than the height of the card interface, the length of the long side of the card block is less than the height of the card cavity, and the height of the connecting plate is adapted to the thickness of the card interface.

[0021] Furthermore, a rectangular galvanized steel lining is provided inside the plastic-steel profile, and a plastic-steel cavity is provided around the galvanized steel lining.

[0022] The benefits of this improved solution include: galvanized steel offers high strength and durability, significantly increasing the overall strength and load-bearing capacity of the plastic-steel profile. The galvanized steel lining makes the plastic-steel profile more stable when subjected to external forces, reducing the possibility of deformation and breakage.

[0023] Furthermore, the number of the plastic-steel cavities is 10, and the thickness of the galvanized steel lining is 1.5 mm.

[0024] Furthermore, the insulation board is filled between the outer frame profile and the plastic-steel profile. The insulation board is used for heat preservation and is made of high-density polyurethane.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are: high-density polyurethane has a low thermal conductivity, which can effectively prevent heat transfer, thereby improving the thermal insulation effect.

[0026] Furthermore, the outer frame body is provided with the drain port, and the drain port is located above the clamping groove.

[0027] Furthermore, the composite rubber strip is an EPDM automotive-grade rubber strip.

[0028] Compared with the prior art, the fixed frame glass structure of the aluminum-plastic composite door and window provided by the present invention has the following advantages: the composite door and window adopts a combined design of aluminum outer frame and plastic inner frame profile, which has the following advantages:

[0029] (1) The aluminum alloy outer frame has high strength and corrosion resistance, can withstand large external forces, and ensure the stability of doors and windows.

[0030] (2) The plastic inner frame itself has good thermal insulation performance, and the outer frame profile and the plastic steel profile are filled with insulation boards, which can effectively block heat transfer, reduce the temperature difference between indoor and outdoor, and save energy.

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

In this embodiment, it includes glass 10, a composite adhesive strip 11, a pressure wire 12, an outer frame profile 13, a plastic steel profile 14, an insulation board 15, a drain port 16 and a snap 17. The outer side of the glass 10 is fixedly connected to the outer frame profile 13 through the composite adhesive strip 11, and the inner side of the glass 10 is fixedly connected to the pressure wire 12 through another composite adhesive strip 11. The hook at the lower end of the pressure wire 12 is slidably installed in the groove at the top of the plastic steel profile 14. The plastic steel profile 14 is arranged on the inner side of the outer frame profile 13. The plastic steel profile 14 and the outer frame profile 13 are connected by the snap 17. The outer frame profile 13 is made of aluminum and the plastic steel profile 14 is made of plastic.

[0044] Glass 10 uses triple-glass, double-cavity, double-pane, double-silver low-e insulation glass with a K value of less than 0.75w / kh;

[0045] 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] 0.75w / kh means that for every square meter of window area and every temperature difference of 1 degree Celsius, the heat transferred through this piece of glass per hour is less than 0.75 watts.

[0047] Triple glass: refers to the glass consisting of three layers of glass.

[0048] 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).

[0049] Double Silver Low-E: refers to low-emissivity coated glass. "Double Silver" means both sheets of Low-E glass are coated with a low-emissivity coating. Double Silver offers better insulation than single Silver Low-E glass.

[0050] The composite adhesive strip 11 not only increases the heat preservation performance of the glass, but also ensures that the glass is not broken.

[0051] Among them, in the above technical solution, the outer frame profile 13 includes an outer frame body 131 and a snap-in groove 132. The outer side of the outer frame body 131 is a flat structure. The snap-in groove 132 is located in the middle of the inner side of the outer frame body 131. The snap-in groove 132 includes a snap-in cavity 1321 and a snap-in interface 1322. The height of the snap-in interface 1322 is less than the height of the snap-in cavity 1321.

[0052] Further, in the above technical solution, the snap fitter 17 includes a base 171, a connecting plate 172, a snap-fit ​​block 173, a first through hole 174, a second through hole 175, a fixed shaft 176 and a groove 177. The base 171 is a square structure. The central axis of the four side walls of the base 171 is provided with a groove 177. The top surface of the base 171 is provided with a first through hole 174. The first through hole 174 is a rectangular structure. The midpoint of the first through hole 174 coincides with the midpoint of the top surface of the base 171. The length of the first through hole 174 is equal to the length of the second through hole 175. A connecting plate 172 is fixedly connected on both sides of the edge, and the connecting plate 172 is fixedly connected to the clamping block 173. The clamping block 173 is a rectangular structure. The size of the clamping block 173 is the same as the size of the first through hole 174. A second through hole 175 is provided on the top surface of the clamping block 173. The second through hole 175 is connected to the first through hole 174. The fixed shaft 176 passes through the second through hole 175 and the first through hole 174 from top to bottom and is fixedly connected to the side wall of the plastic-steel profile 14. The fixed shaft 176 is rotatably connected to the base 171 and the clamping block 173.

[0053] The fastener 17 is made of plastic. This plastic fastener 17 has a certain degree of deformability. Acting as an intermediate buffer, it can, to a certain extent, absorb the expansion and contraction of the two materials under temperature fluctuations. Because plastic has a lower elastic modulus, it can better withstand the stress caused by temperature fluctuations, thereby reducing stress concentration and the risk of cracking at the joint.

[0054] Furthermore, in the above technical solution, the second through hole 175 is a recessed structure, with the periphery being higher and the middle being lower.

[0055] Furthermore, in the above technical solution, the length of the long side of the snap-in block 173 is longer than the height of the card interface 1322, the length of the short side of the snap-in block 173 is less than the height of the card interface 1322, the length of the long side of the snap-in block 173 is less than the height of the snap-in cavity 1321, and the height of the connecting plate 172 is adapted to the thickness of the card interface 1322.

[0056] Furthermore, in the above technical solution, a rectangular galvanized steel lining 142 is provided inside the plastic-steel profile 14 , and a plastic-steel cavity 141 is provided around the galvanized steel lining 142 .

[0057] Furthermore, in the above technical solution, the number of the plastic-steel cavities 141 is 10, and the thickness of the galvanized steel lining 142 is 1.5 mm.

[0058] Furthermore, in the above technical solution, the space between the outer frame profile 13 and the plastic-steel profile 14 is filled with a thermal insulation board 15 , which is used for heat preservation and is made of high-density polyurethane.

[0059] Furthermore, in the above technical solution, a drain outlet 16 is provided on the outer frame body 131 , and the drain outlet 16 is located above the engaging groove 132 .

[0060] Furthermore, in the above technical solution, the composite rubber strip 11 is an EPDM automotive-grade rubber strip.

[0061] When fixing the outer frame profile 13 and the plastic-steel profile 14, first fix the clamp 17 on the side wall of the plastic-steel profile 14, and rotate the base 171 to drive the clamping block 173 to rotate to the appropriate position, align the clamping groove 132 with the clamp 17, so that the short side of the clamping block 173 can smoothly pass through the clamping interface 1322, and the clamping block 173 as a whole enters the clamping cavity 1321. At this time, the connecting plate 172 is opposite to the clamping interface 1322. Use the adjustment tool to extend into the groove 177 from the gap between the outer frame profile 13 and the plastic-steel profile 14, bend the adjustment tool to drive the base 171 to rotate 90 degrees, which in turn drives the clamping block 173 to rotate. The long side of the clamping block 173 replaces the original short side. After the adjustment is completed, Figure 1As shown, at this time, the card interface 1322 is inserted into the gap between the two connecting plates 172. Thus, the connection between the outer frame profile 13 and the plastic steel profile 14 is achieved.

[0062] Specifically, the principle of the present invention is as follows: when fixing the outer frame profile 13 and the plastic steel profile 14, first the snap 17 is fixed to the side wall of the plastic steel profile 14, and the rotating base 171 drives the snap block 173 to rotate to a suitable position, aligning the snap groove 132 with the snap 17, so that the short side of the snap block 173 can smoothly pass through the snap interface 1322, and the snap block 173 as a whole enters the snap cavity 1321, at which point the connecting plate 172 is opposite to the snap interface 1322. Use an adjustment tool to extend into the groove 177 from the gap between the outer frame profile 13 and the plastic steel profile 14, bend the adjustment tool to drive the base 171 to rotate 90 degrees, which in turn drives the snap block 173 to rotate, and the long side of the snap block 173 replaces the original short side. After the adjustment is completed, Figure 1 As shown, at this time, the card interface 1322 is inserted into the gap between the two connecting plates 172.
