Description

Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and in particular relates to a thermal insulation aluminum-clad wood lower frame structure. Background Art

[0002] Aluminum clad wood frames are a material that combines aluminum and wood, and are often used to make the frame part of windows, doors or other building structures. This frame is usually composed of an internal wood frame with an external aluminum cladding, combining the natural beauty of wood with the durability and stability of aluminum. However, despite the high strength and beauty of aluminum clad wood, there are certain problems with its water tightness. The water tightness of aluminum clad wood is affected by the properties of the material itself. As one of the main components of aluminum clad wood structures, wood's natural fiber structure determines that it is easy to absorb moisture, and wood has relatively poor water resistance. This means that in a humid environment, wood may swell, deform, or even rot, resulting in the water tightness of aluminum clad wood structures being affected.

[0003] Water seepage will gradually corrode the building materials at the joints between the wall and the window frame, such as bricks and cement, causing the wall materials at the joints to become loose, crack, or even fall off, seriously affecting the stability and safety of the building structure. After water seepage penetrates into the wall, it is easy to cause damage to the thermal insulation materials, sound insulation materials or other decorative materials inside the wall, affecting the insulation and sound insulation effects of the wall, and even causing mold growth, corrosion of metal components and other problems.

[0004] In summary, the existing aluminum-clad wood lower frame has poor water tightness and easily leads to water ingress at the joints. Utility Model Content

[0005] In view of this, the utility model provides a heat-insulating aluminum-clad wood lower frame structure, which can solve the problem that the existing aluminum-clad wood lower frame has poor water tightness and easily causes water ingress at the joints.

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

[0007] The utility model provides an aluminum-clad wood lower frame structure with thermal insulation, which includes passive glass, window sashes and connecting buckles. The bottom of the passive glass is fixedly connected with a first thermal insulation layer and the window sash. The window sash is fixedly connected to the first thermal insulation layer through the connecting buckle. The window sash is used to fix the passive glass. The window sash is fixedly connected to an aluminum profile through a first rubber strip. The aluminum profile is located below the window sash. The first thermal insulation layer is fixedly connected to the aluminum profile through the first rubber strip. The aluminum profile is fixedly connected to the second thermal insulation layer through another connecting buckle. The first thermal insulation layer and the second thermal insulation layer are used for thermal insulation. The first thermal insulation layer and the second thermal insulation layer are fixedly connected through a second rubber strip. A drainage board is fixedly connected to the second thermal insulation layer, and the drainage board is used for drainage.

[0008] The technical effects of a thermal insulation aluminum-clad wood lower frame structure provided by the utility model are as follows: by setting a first thermal insulation layer and a second thermal insulation layer, the overall thermal insulation performance of the aluminum-clad wood frame can be effectively improved, the conduction and loss of heat can be reduced, the indoor temperature can be more stable, and the consumption of heating and cooling energy can be reduced, thereby achieving the effect of energy saving. By improving the thermal insulation performance, the aluminum-clad wood frame can be installed with a thermal insulation layer to improve indoor comfort. It can reduce the difference between indoor and outdoor temperatures, make the indoor environment more comfortable, and avoid the discomfort caused by alternating hot and cold. The first thermal insulation layer and the second thermal insulation layer can effectively prevent the condensation problem caused by the difference between indoor and outdoor temperatures. By reducing the thermal bridge effect, the temperature of the frame surface can be reduced, and the possibility of water vapor condensing on the frame surface can be reduced, thereby reducing the occurrence of condensation. It also effectively reduces the influence of thermal expansion and contraction of the frame and temperature changes on the frame, reduces the stress of the frame, and prolongs the service life of the frame. At the same time, the structure of the first thermal insulation layer and the second thermal insulation layer can maintain good thermal insulation performance while reducing weight, thereby reducing the load on the building structure.

[0009] Aluminum profiles are lightweight and strong, making the window frame structure lighter while providing adequate support and stability, which helps reduce the building's deadweight and lowers the structural load. Aluminum has good thermal conductivity, which is beneficial to the heat dissipation of the window frame, avoiding problems such as unstable indoor temperature or condensation caused by poor thermal conductivity of the window frame. Passive glass can significantly reduce the energy consumption of a building. By optimizing thermal insulation and reducing the temperature difference between indoor and outdoor, passive glass helps reduce the use of heating and cooling systems, thereby reducing energy consumption and related costs. The structural design of passive glass can also provide good sound insulation, reduce the impact of outdoor noise on the interior, and create a quieter indoor environment, which is conducive to living and working.

[0010] If there is too much water under the aluminum-clad wood frame, it is easy to cause problems such as wood rot, mold growth and metal oxidation. Through the drainage board, rainwater can be discharged in time, reducing the water accumulation under the frame, which helps to extend the service life of the frame. The accumulated water may leave water stains on the lower part of the aluminum-clad wood frame, affecting the appearance. The drainage board effectively drains rainwater, avoids this problem, and keeps the appearance of the building clean and beautiful.

[0011] On the basis of the above technical solution, the thermal insulation aluminum-clad wood lower frame structure of the utility model can also be improved as follows:

[0012] Among them, the first thermal insulation layer includes a first thermal insulation plastic material and a first pine integrated material, the first thermal insulation plastic material is fixedly connected to the first pine integrated material, and the first thermal insulation plastic material is fixedly connected to the window sash via the connecting buckle.

[0013] The beneficial effects of adopting the above improved solution are: K of the first thermal insulation plastic material and the second thermal insulation plastic material is less than 0.06w / ㎡.K, ρ=350kg / m 3 .

[0014] K is the thermal conductivity coefficient. A value less than 0.06 indicates excellent thermal insulation performance. ρ = 350 kg / m 3 This means that the material has a density of 350 kg / m3, indicating that the material has low structural strength.

[0015] Furthermore, the second thermal insulation layer includes a second thermal insulation plastic material and a second pine integrated material, the second thermal insulation plastic material and the second pine integrated material are fixedly connected, the second pine integrated material and the aluminum profile are fixedly connected via the connecting buckle, and the first pine integrated material and the second pine integrated material are fixedly connected via the second rubber strip.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the first camphor pine integrated material and the second camphor pine integrated material have high strength and stability and can provide good structural support. Combined with the characteristics of the first thermal insulation plastic material and the second thermal insulation plastic material, the stability of the overall structure can be enhanced while maintaining lightweight. The outer layer of the PS crust foam forms a dense "skin" that can effectively reduce heat conduction. Combined with the thermal insulation performance of the camphor pine integrated material, the thermal insulation effect of the overall structure can be further improved, which helps to maintain a stable indoor temperature and improve energy efficiency.

[0017] Furthermore, the first thermal insulation plastic material, the second thermal insulation plastic material and the aluminum profile are fixedly connected via the first rubber strip.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the first rubber strip is an EPDM automotive-grade aging-resistant rubber strip with a hollow soft-hard composite structure.

[0019] Furthermore, the drain board is a Z-shaped retractable structure, one end of the drain board is fixedly connected to the second thermal insulation plastic material by bolts, and the other end of the drain board extends to the outside of the aluminum profile.

[0020] The beneficial effects of adopting the above improved solution are: the retractable drain board can be adjusted according to different situations to adapt to the needs and changes of different buildings. This flexibility means that the drain board can be installed under the aluminum-clad wood frame at different heights or lengths to ensure that it can effectively drain water. The flexibility of the retractable drain board makes it easier to maintain and clean. The length of the drain board can be adjusted as needed to clean and maintain the accumulated water under the frame, reducing the difficulty and cost of maintenance.

[0021] Furthermore, a groove is provided on a side of the second thermal insulation plastic material away from the second camphor-pine integrated material, and a height of the groove is consistent with a height of an end portion of the drainage board.

[0022] Furthermore, the bottom end of the aluminum profile is flush with the highest point of the groove.

[0023] Furthermore, the aluminum profile is provided with through holes penetrating the aluminum profile from top to bottom, and the through holes are used to drain rainwater.

[0024] Furthermore, the connection between the window sash and the connecting buckle is filled with thermal insulation cotton.

[0025] Furthermore, the first thermal insulation plastic material and the first camphor-pine integrated material are both PS crusted foamed plastic materials.

[0026] Compared with the prior art, the utility model provides a heat-insulating aluminum-clad wood lower frame structure with beneficial effects: by setting the first insulation layer and the second insulation layer, the overall insulation performance of the aluminum-clad wood frame can be effectively improved, the conduction and loss of heat can be reduced, the indoor temperature can be more stable, and the consumption of heating and cooling energy can be reduced, thereby achieving the effect of energy saving. By improving the thermal insulation performance, the aluminum-clad wood frame can be installed with an insulation layer to improve indoor comfort. It can reduce the difference between indoor and outdoor temperatures, make the indoor environment more comfortable, and avoid the discomfort caused by alternating hot and cold. The first insulation layer and the second insulation layer can effectively prevent the condensation problem caused by the difference between indoor and outdoor temperatures. By reducing the thermal bridge effect, the temperature of the frame surface can be reduced, and the possibility of water vapor condensing on the frame surface can be reduced, thereby reducing the occurrence of condensation. It also effectively reduces the influence of thermal expansion and contraction and temperature changes on the frame, reduces the stress of the frame, and prolongs the service life of the frame. At the same time, the structure of the first insulation layer and the second insulation layer can maintain good thermal insulation performance while reducing weight, reducing the load on the building structure.

[0027] Aluminum profiles are lightweight and strong, making the window frame structure lighter while providing adequate support and stability, which helps reduce the building's deadweight and lowers the structural load. Aluminum has good thermal conductivity, which is beneficial to the heat dissipation of the window frame, avoiding problems such as unstable indoor temperature or condensation caused by poor thermal conductivity of the window frame. Passive glass can significantly reduce the energy consumption of a building. By optimizing thermal insulation and reducing the temperature difference between indoor and outdoor, passive glass helps reduce the use of heating and cooling systems, thereby reducing energy consumption and related costs. The structural design of passive glass can also provide good sound insulation, reduce the impact of outdoor noise on the interior, and create a quieter indoor environment, which is conducive to living and working.

[0028] If there is too much water under the aluminum-clad wood frame, it is easy to cause problems such as wood rot, mold growth and metal oxidation. Through the drainage board, rainwater can be discharged in time, reducing the water accumulation under the frame, which helps to extend the service life of the frame. The accumulated water may leave water stains on the lower part of the aluminum-clad wood frame, affecting the appearance. The drainage board effectively drains rainwater, avoids this problem, and keeps the appearance of the building clean and beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0034] like Figure 1As shown, it is an embodiment of a thermal insulation aluminum-clad wood lower frame structure provided by the utility model. In this embodiment, it includes passive glass 10, window sash 11 and connecting buckles 12. The bottom of the passive glass 10 is fixedly connected with a first insulation layer 16 and the window sash 11. The window sash 11 is fixedly connected to the first insulation layer 16 through the connecting buckle 12. The window sash 11 is used to fix the passive glass 10. The window sash 11 is fixedly connected to the aluminum profile 13 through a first adhesive strip 14. The aluminum profile 13 is located below the window sash 11. The first insulation layer 16 is fixedly connected to the aluminum profile 13 through the first adhesive strip 14. The aluminum profile 13 is fixedly connected to the second insulation layer 17 through another connecting buckle 12. The first insulation layer 16 and the second insulation layer 17 are used for heat insulation. The first insulation layer 16 and the second insulation layer 17 are fixedly connected through a second adhesive strip 15. A drainage board 21 is fixedly connected to the second insulation layer 17, and the drainage board 21 is used for drainage.

[0035] The connecting buckle 12 is made of nylon, has good wear resistance and durability, is not easy to break or deform, and can maintain stable performance for a long time.

[0036] ρ of the first pine glued material 162 and the second pine glued material 172 = 500 kg / m 3 , uf<1.2W / ㎡.K.

[0037] ρ=500kg / m 3 This means that the density of the material is 500 kg / m3, indicating that it has a high structural strength. uf<1.2W / ㎡·K: This means that the thermal conductivity of the material is lower than 1.2W / ㎡·K, indicating that the material has a low thermal conductivity and can effectively reduce heat conduction.

[0038] The first thermal insulation layer 16 and the second thermal insulation layer 17 combine the advantages of the two materials so that the thermal insulation performance reaches Uf<1.0W / ㎡.K.

[0039] When it rains, rainwater comes into contact with the passive glass 10, the sash 11 and the aluminum profile 13. Part of the rainwater slides out along the edge of the aluminum profile 13, and the other part of the rainwater flows from the through holes 19 on the aluminum profile 13 to the drain board 21, and is then drained by the drain board 21. Since the length of the drain board 21 exceeds the edge of the aluminum profile 13, the rainwater drained through the drain board 21 will not come into contact with the joints between the insulation wall and the frame, thereby preventing rainwater from penetrating from the joints.

[0040] Among them, in the above technical solution, the first insulation layer 16 includes a first insulation plastic material 161 and a first pine integrated material 162, the first insulation plastic material 161 and the first pine integrated material 162 are fixedly connected, and the first insulation plastic material 161 and the window sash 11 are fixedly connected via a connecting buckle 12.

[0041] The passive glass 10 is a double silver low-e+16Ar+5 silver low-e+16Ar+5 warm edge argon-filled passive glass, and the K value is less than 0.71.

[0042] Double silver low-e means that the glass has a double layer of silver low-e coating. The low-e coating helps reduce the transfer of heat and ultraviolet rays, so they help maintain a stable indoor temperature and reduce the damage of ultraviolet rays to indoor furniture and floors.

[0043] 16Ar means that the middle of the glass is filled with a 16 mm wide layer of argon, which is a low thermal conductivity gas with a lower thermal conductivity than air. This gas filling layer helps reduce the conduction of heat, thereby improving the thermal insulation performance of the window.

[0044] 5 Silver Low-E glass has five layers of silver low-e coating on it, which is designed to further reduce the transmission of heat and ultraviolet rays.

[0045] 5 Warm edge argon filling refers to 5mm warm edge glass.

[0046] K value usually refers to the thermal conductivity coefficient, which is a parameter used to describe the thermal conductivity of materials. It is usually expressed as the thermal conductivity of materials per unit thickness per unit time under unit temperature gradient. In construction projects, K value is often used to evaluate the thermal insulation performance of building materials, that is, its ability to resist heat conduction. When the K value is less than 0.71, it means that the thermal conductivity of the material is relatively low.

[0047] Furthermore, in the above technical scheme, the second thermal insulation layer 17 includes a second thermal insulation plastic material 171 and a second pine integrated material 172, the second thermal insulation plastic material 171 and the second pine integrated material 172 are fixedly connected, the second pine integrated material 172 and the aluminum profile 13 are fixedly connected by a connecting buckle 12, and the first pine integrated material 162 and the second pine integrated material 172 are fixedly connected by a second rubber strip 15.

[0048] The second rubber strip 15 is a wrapping structure.

[0049] Furthermore, in the above technical solution, the first thermal insulation plastic material 161 , the second thermal insulation plastic material 171 and the aluminum profile 13 are fixedly connected via the first rubber strip 14 .

[0050] The soft part of the hollow soft-hard composite structure can effectively fill the gap between the window frame and the glass, while the hard part provides better support and stability, thereby ensuring the sealing performance of the window and preventing the intrusion of air, water vapor and dust. At the same time, the first rubber strip 14 has good aging resistance and is not easily affected by factors such as ultraviolet rays, oxidation, and temperature changes. It can maintain a good sealing effect for a long time and provide automotive-grade sealing effect.

[0051] Furthermore, in the above technical solution, the drain board 21 is a Z-shaped retractable structure, one end of the drain board 21 is fixedly connected to the second thermal insulation plastic material 171 by bolts, and the other end of the drain board 21 extends to the outside of the aluminum profile 13.

[0052] Furthermore, in the above technical solution, a groove 20 is provided on the side of the second thermal insulation plastic material 171 away from the second camphor-pine integrated material 172 , and the height of the groove 20 is consistent with the height of the end of the drainage board 21 .

[0053] Furthermore, in the above technical solution, the bottom end of the aluminum profile 13 is flush with the highest point of the groove 20 .

[0054] Furthermore, in the above technical solution, the aluminum profile 13 is provided with through holes 19 penetrating the aluminum profile 13 from top to bottom, and the through holes 19 are used to drain rainwater.

[0055] Furthermore, in the above technical solution, the connection between the window sash 11 and the connecting buckle 12 is filled with thermal insulation cotton 18.

[0056] Furthermore, in the above technical solution, the first thermal insulation plastic material 161 and the first camphor-pine integrated material 162 are both PS crusted foamed plastic materials.

[0057] Specifically, the principle of the utility model is that the connecting buckle 12 is made of nylon, has good wear resistance and durability, is not easy to break or deform, and can maintain stable performance for a long time.

[0058] The first pine glued material 162 and the second pine glued material 172 have a value of ρ=500 kg / m 3 , uf<1.2W / ㎡.K.

[0059] ρ=500kg / m 3 This means that the density of the material is 500 kg / m3, indicating that it has a high structural strength. uf<1.2W / ㎡·K: This means that the thermal conductivity of the material is lower than 1.2W / ㎡·K, indicating that the material has a low thermal conductivity and can effectively reduce heat conduction.

[0060] The first thermal insulation layer 16 and the second thermal insulation layer 17 combine the advantages of the two materials so that the thermal insulation performance reaches Uf<1.0W / ㎡.K.

[0061] When it rains, rainwater comes into contact with the passive glass 10, the sash 11 and the aluminum profile 13. Part of the rainwater slides out along the edge of the aluminum profile 13, and the other part of the rainwater flows from the through holes 19 on the aluminum profile 13 to the drain board 21, and is then drained by the drain board 21. Since the length of the drain board 21 exceeds the edge of the aluminum profile 13, the rainwater drained through the drain board 21 will not come into contact with the joints between the insulation wall and the frame, thereby preventing rainwater from penetrating from the joints.
