Description

Technical Field

[0001] This invention relates to the field of building energy-saving renovation technology, specifically to a method and system for energy-saving renovation of doors and windows in old buildings with double-layer vacuum glass. Background Technology

[0002] Currently, many old buildings still use traditional single-pane or ordinary double-glazed windows and doors. These windows and doors generally suffer from poor thermal insulation, insufficient airtightness, and poor sound insulation, leading to cold winters and hot summers, significantly increasing residents' energy costs, and exacerbating energy consumption and carbon emissions. This contradicts my country's green and low-carbon transformation and the achievement of its "dual-carbon" goals. Therefore, it is necessary to carry out energy-saving renovations on the windows and doors of old buildings.

[0003] Patent application CN202410112285.1 discloses a method for low-carbon and energy-saving renovation of existing building exterior windows, including the following steps: reinforcing the connection between the original window frame and the wall with screws; fitting the bottom of the modified window frame onto the outside of the original window frame; connecting the sides of the modified window frame and the original window frame with connecting sleeves; pouring concrete into the original window frame through the connecting sleeves; and finally driving connecting screws into the connecting sleeves. This energy-saving renovation method installs a new modified window frame without removing the original window frame, thus avoiding damage to the wall structure. It strengthens the connection between the original window frame and the wall, improving the bonding strength between the modified window frame and the window frame. However, the renovated window does not have heat insulation and energy-saving effects.

[0004] Patent application CN118728122A discloses a method for energy-saving renovation of doors and windows in old buildings. The method includes the following steps: repairing damaged parts of old doors and windows to restore their usability; utilizing existing doors and windows and dividing them into the same facade sections, and then superimposing a new plastic door and window on the interior side; the superposition method is as follows: the new and old door and window frames are bonded together as a whole using thickened, high-strength EVA black foam double-sided adhesive strips and structural adhesive, sharing the vertical and horizontal loads. This solution uses a thermally broken composite frame material composed of new and old doors and windows to block heat conduction caused by indoor and outdoor temperature differences, and uses composite glass to block heat and noise conduction through the glass, effectively enhancing the heat insulation and sound insulation performance of the renovated doors and windows. It fully utilizes the inherent value of the original doors and windows, and the energy-saving renovation does not require the removal of the original old doors and windows, does not damage the original interior and exterior decoration of the building, and does not generate construction waste.

[0005] This method of energy-saving renovation for old building doors and windows mainly involves adding a new plastic door or window to the outside of the old ones. While this can effectively utilize the old doors and windows to achieve energy-saving goals, it results in an unsightly appearance for the old windows. Furthermore, with age, the double-sided adhesive strips and structural adhesive will deteriorate, easily causing the plastic door or window to separate from the old one, potentially leading to accidents and reduced sound insulation. Additionally, many existing old doors and windows are sliding windows, and attaching a new plastic door or window to the outside can easily prevent the window sash from sliding properly. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for energy-saving renovation of old building doors and windows with double-layer vacuum glass. It aims to improve the existing methods for renovating old windows, which result in poor appearance of old windows. At the same time, with the increase of use time, the double-sided adhesive strips and structural adhesive will age, which can easily cause the plastic doors and windows to separate from the old doors and windows, which can easily lead to accidents and reduce the sound insulation effect. In addition, the existing methods are not suitable for the problems of old sliding doors and windows.

The fixing groove has multiple bolt holes on its inner side and symmetrical slots on both sides inside the fixing groove. The aesthetic frame has locking edges on both its outer and inner sides. The aesthetic frame is embedded in the fixing groove, and the locking edges engage with the slots. The outer side of the aesthetic frame has textures or patterns.

[0011] Preferably, it also includes an auxiliary reinforcement mechanism, which includes clamping feet and bidirectional screws. Four clamping feet are provided, which are used to clamp at the corners of the window sash frame when repairing the window sash frame. Adjacent clamping feet are connected by bidirectional screws, which are used to tighten the distance between the clamping feet by turning the bidirectional screws to fix the window sash frame.

[0012] Preferably, the clamping foot has a right-angle structure, and a support plate is provided on the bottom inner side of the clamping foot. Two connectors are provided on the outer side of the clamping foot, and the two connectors are staggered vertically to avoid interference between the transverse bidirectional screw and the longitudinal bidirectional screw. A threaded hole is provided in the middle of the connector, and the bidirectional screw is threadedly connected to the threaded hole. A hexagon is provided between the threads of the bidirectional screw in two different directions for turning the bidirectional screw.

[0013] According to a second aspect of the present invention, the present invention provides a method for energy-saving renovation of double-glazed vacuum glass doors and windows in old buildings, the specific steps of which are as follows: S100. Remove the window sash bracket from the window frame, clean the surface of the window frame, and repair the window frame. S200. Grind the surface of the window sash frame smooth, clean the window sash frame, and spray the surface of the window sash frame with anti-rust paint. Then measure the internal dimensions of the window sash frame and the thickness of the frame, and customize the matching double-layer vacuum glass body, sealing wrapping strip and clamping components. S300. Prepare a double-layered vacuum glass body of suitable size, ensuring that the vacuum level of the vacuum chamber meets the requirements; apply a ring of sealant to the outer surface of the double-layered vacuum glass body, ensuring that the surfaces are close together before the sealant cures, and check the glass quality after the sealant has cured. S400: The double-layer vacuum glass body, together with the sealing wrapping strip, is installed on the inside of the window frame, and then the double-layer vacuum glass body is stably fixed to the inside of the window frame using the clamping assembly. S500. Install the window sash bracket containing the vacuum glass body onto the window frame to ensure that the window sash bracket can be opened and closed normally. S600: Adjust the flexibility and stability of doors and windows, and test the thermal insulation effect and airtightness. If they fail to meet the requirements, targeted adjustments are needed. S700: Clean up the construction site, provide maintenance instructions, regularly check the tightness of mechanical fixing mechanisms, the aging of sealing strips and the glass vacuum level, and promptly tighten loose bolts and replace aged sealing strips.

[0014] Preferably, the specific steps for repairing the window frame in step S100 are as follows: S110. Remove rust from corroded areas and clean the surface of the window frame after rust removal. S120. Apply a protective film around the window frame, then spray anti-rust paint to prevent the anti-rust paint from being sprayed on the wall. S130.

After ensuring that the window frame is level, use new expansion bolts to fix the window frame to the wall and remove the original rusted collision bolts. S160. Then, use expanding foam to fill the gap between the window frame and the wall; and apply waterproof sealant between the outside of the window and the wall.

[0015] Preferably, in step S200, if the window sash frame is severely damaged and needs to be repaired, an auxiliary reinforcement mechanism is used to insert the four corners of the window sash frame into the four clips respectively; then, the two longitudinal bidirectional screws and the two transverse bidirectional screws are turned to reshape the window sash frame. After the reshaping is completed, the damaged parts of the window sash frame are repaired, and the loose parts of the window sash frame are re-glued and fixed. After the window sash frame is shaped, it can be taken out from the auxiliary reinforcement mechanism.

[0016] Preferably, the specific steps for installing the double-layer vacuum glass body inside the window sash frame in step S400 are as follows: S410. Clean the inside of the window sash frame to ensure that the inside of the window sash frame is flat; S420.

The system uses a double-layer vacuum glass body 1 as the core energy-saving component. A sealing strip 2 is fitted on the outer side of the double-layer vacuum glass body 1. After the double-layer vacuum glass body 1 and the sealing strip 2 are combined, they are embedded into the inner side of the window sash frame of the old building door and window. At the same time, pressing components 3 are symmetrically arranged on both sides of the double-layer vacuum glass body 1. The pressing components 3 are fixedly installed on the window sash frame of the old building door and window, and the end of the pressing component 3 is stably pressed against the side of the sealing strip 2, thereby realizing the positioning and sealing fixation of the double-layer vacuum glass body 1.

[0029] like Figure 2 and Figure 3 As shown, the double-layer vacuum glass body 1 is composed of two tempered glass pieces 11, a supporting spacer 12, and a sealant 13. The two tempered glass pieces 11 are arranged in a parallel manner. The supporting spacer 12 is located in the gap between the two tempered glass pieces 11. The supporting spacer 12 is made of stainless steel. The outer edge of the supporting spacer 12 is machined to form a flat angle 121 structure. The interior of the supporting spacer 12 adopts a hollow design, and the hollow cavity is filled with molecular sieves. The sealant 13 is arranged around the outside of the supporting spacer 12 between the two tempered glass pieces 11. The bottom sides of the sealant 13 extend to form an edge 131. The edge 131 tightly wraps around the flat angle 121 of the supporting spacer 12 to ensure the sealing and structural stability of the vacuum cavity.

[0030] like Figure 4 As shown, the inner side of the sealing strip 2 is machined with a sleeve groove 21. The sleeve groove 21 is adapted to the outer contour of the double-layer vacuum glass body 1 and is completely fitted onto the outer side of the double-layer vacuum glass body 1. Side adhesive strips 22 are integrally provided on both sides of the sealing strip 2. The side adhesive strips 22 are tightly attached to the surface of the double-layer vacuum glass body 1.

[0033] like Figure 9 As shown in the figure, this embodiment provides a method for energy-saving renovation of double-glazed vacuum glass doors and windows in old buildings. This method is implemented based on the above-mentioned double-glazed vacuum glass energy-saving renovation system for old buildings. The specific operation process is as follows: S100. Completely disassemble the window sash frame from the window frame, clean and remove debris, dust, and old sealing material from the surface of the window frame, and then carry out a comprehensive repair of the window frame. During the repair, first thoroughly remove the rust from the rusted parts of the window frame. After the rust removal is completed, clean the surface of the window frame again, apply a protective film around the window frame, and then spray anti-rust paint to avoid contaminating the wall with the anti-rust paint. Next, check the degree of deformation of the window frame. For minor deformation, use corner reinforcements to correct and reinforce it. For severe deformation, cut and replace the deformed parts locally. Clean the gap between the window frame and the wall, remove loose and ineffective filler, and use a spirit level to calibrate the level of the window frame. After confirming that it is level, replace it with new expansion bolts to firmly fix the window frame to the wall. Remove the original rusted and ineffective expansion bolts. Finally, fill the gap between the window frame and the wall with expanding foam, and apply waterproof glue to the junction of the window and the wall on the outside to complete the repair and sealing of the window frame.

[0034] S200. After smoothing and cleaning the surface of the window sash frame, spray anti-rust paint evenly on the surface of the window sash frame. Accurately measure the internal dimensions and frame thickness of the window sash frame. Based on the measurement data, customize the size-fitting double-layer vacuum glass body 1, sealing wrapping strip 2, and pressing component 3. If the window sash frame is severely damaged, it needs to be repaired first. During repair, insert the four corners of the window sash frame into the four clips 41 respectively, and turn the two longitudinal bidirectional screws 42 and the two transverse bidirectional screws 42 in sequence to complete the shaping and correction of the window sash frame. After shaping, repair the damaged parts of the window sash frame and re-apply glue to fix the loose parts. After the window sash frame is completely shaped, remove it from the auxiliary reinforcement mechanism 4.

[0035] S300. Process and prepare the double-layer vacuum glass body 1 according to the customized size, ensuring that the vacuum degree of the vacuum chamber meets the energy-saving standard requirements. Apply a ring of sealant 13 evenly to the outer surface of the double-layer vacuum glass body 1, and control the surface state of the sealant 13 before curing to meet the construction requirements. After the sealant 13 is completely cured, conduct a comprehensive inspection of the glass quality. After confirming that there are no problems such as damage or air leakage, proceed to the next process.

[0036] S400. First, clean the inside of the window sash frame and ensure the surface is flat. Completely fit the sealing strip 2 onto the double-layer vacuum glass body 1. Then, embed the double-layer vacuum glass body 1 with the sealing strip 2 into the inside of the window sash frame, so that the sealing strip 2 is pressed and adhered to the inside of the window sash frame by the double-layer vacuum glass body 1. Attach the pressure frame 31 of the clamping component 3 to the two sides of the window sash frame, ensuring that the pressure edge 311 of the pressure frame 31 is tightly pressed against the side of the sealing strip 2. Fix the pressure frame 31 to the window sash frame by passing bolts through the bolt holes 314 of the pressure frame 31. At the same time, apply sealing black glue to the connection position of the double-layer vacuum glass body 1, the sealing strip 2, and the clamping component 3 to further improve the sealing performance. Finally, embed and fix the beautification frame 32 into the fixing groove 312 of the pressure frame 31 to complete the installation of the clamping component 3 and the beautification of the appearance.

[0037] S500. Reinstall the window sash frame with the double-layer vacuum glass body 1 assembled on the window frame, and adjust the opening and closing status of the window sash frame to ensure that the window sash frame can open and close smoothly and normally.

[0038] S600. Conduct flexibility and stability tests on the renovated doors and windows, and test the performance indicators such as thermal insulation and airtightness of the doors and windows. If the test results are unqualified, make targeted adjustments and repairs to the problematic parts until all indicators meet the standards.

[0039] S700: Thoroughly clean the construction site, provide the user with complete maintenance instructions, and regularly check the tightness of the mechanical fixing mechanism in the system, the aging of the 13 sealants, and the vacuum level of the glass. Tighten loose bolts in time and replace 13 aged and ineffective sealants to ensure the long-term stable operation of doors and windows after the renovation.

[0040] In summary, compared with existing technologies, the renovation method of this application does not require the complete demolition of old door and window frames. It only involves pre-treatment and local reinforcement of the window frames, significantly reducing renovation costs and construction time, minimizing construction waste, and reducing damage to building walls. It also avoids the high costs associated with replacing all doors and windows, aligns with existing subsidy policies, and increases willingness to renovate. This method is particularly suitable for large-scale energy-saving renovations of old residential buildings. Furthermore, this renovation method and system are applicable to various types of old doors and windows. The renovation system can install and seal the double-layer vacuum glass body 1 inside the window frame. The double-layer vacuum glass body 1 is easy to install and has good sound insulation, significantly improving the sound insulation of old doors and windows. Simultaneously, the double-layer vacuum glass body 1 uses high-strength tempered glass 11, greatly enhancing the glass's strength and preventing easy breakage. This application also includes an auxiliary reinforcement mechanism 4, facilitating the fixation of the window frame during repairs, preventing frame deformation, and extending the service life of the renovated doors and windows.
