In terms of window maintenance and upgrading, energy-saving renovation technology for doors and windows is gradually attracting people's attention and love. Energy-saving renovation is a technology that saves time and money. It is an advanced technology that improves window performance by retaining the original window frame, upgrading various components and replacing the opening sash components.

[0003] There are three obvious problems with old aluminum windows:

[0004] ①High energy consumption and poor insulation effect: high heat transfer coefficient, poor insulation in winter and summer; relatively simple structure, which leads to the phenomenon of "cold and hot bridge" when the temperature difference between indoor and outdoor is large, affecting the insulation effect. The window frame will become hot in summer and the window surface will be frosted in winter, causing discomfort to the residents.

[0005] ②No sound insulation: The profile cavity is thin, and the filling sound insulation material is insufficient, so the sound is more likely to enter the room, affecting the living environment. ②No sound insulation: The profile cavity is thin, and the filling sound insulation material is insufficient, so the sound is more likely to enter the room, affecting the living environment.

[0006] ③Poor sealing: The structural defects of aluminum alloy windows lead to poor sealing, which makes it easy to leak on rainy days, causing frequent air and rain leaks. Summary of the invention

[0007] In order to overcome the defects of the prior art, the present invention provides a construction process for energy-saving transformation of doors and windows. The technical solution of the present invention is:

[0008] A construction process for energy-saving renovation of doors and windows, comprising the following steps:

[0009] S1. Remove the glass pressure wire fixed on the glass, and then remove the glass pressure wire around each fixed window in turn;

[0014] S6. Fill the area around the glass with heat-insulating and sound-proof cotton strips, and seal the glass with foamed EPDM strips to complete the glass installation in step S3.

[0015] The step S3 is specifically as follows: the spacer strip is made of a warm edge strip, a sealing frame is provided, connectors are eliminated, a spacer strip is directly bent into a continuous corner frame to form a mouth shape, and a corner penetration channel is eliminated.

[0016] The step S4 is specifically as follows:

[0017] 4.1 Filling with argon: After extracting the air, turn off the vacuum pump, open the argon valve, and inject argon into the insulating glass;

At the same time, ensure that there is bonding and sealing performance between the frame of the insulating glass and the sealing frame to prevent gas leakage.

[0019] Sunshade blinds are installed between the added glass and the original glass.

[0024] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.

[0025] See also Figures 1 to 3 The present invention relates to a construction process for energy-saving transformation of doors and windows, comprising the following steps:

[0026] S1. Remove the glass pressure line fixed on the glass (take a spatula, first pry open the glass pressure line on the fixed glass with the spatula), and then remove the glass pressure line around each fixed window in turn;

[0027] S2. After removing the glass pressing wire, clean the glass glue and EPDM strips on the upper glass and remove the glass;

[0028] S3. Prepare two clean glass plates, place a spacer between the two glass plates, and place the spacer between the two glass plates to form a hollow layer; assemble the two glass plates and the spacer together, and fix them with a sealing frame;

[0029] S4. Set up the inflation equipment: install the bracket with the insulating glass on the inflation equipment, ensure that it can be connected with the air chamber of the insulating glass, and then evacuate;

[0030] S5. Install the aluminum alloy gland and place a new type of heat insulation pad between the aluminum alloy gland and the original door and window profiles;

[0031] S6. Fill the area around the glass with heat-insulating and sound-proof cotton strips, and seal the glass with foamed EPDM strips to complete the glass installation in step S3.

[0032] When the glass is installed, the window sash can be processed further, namely: S7, processing the opening window sash, the opening window sash is made of aluminum alloy profiles and composite high-performance polyamide nylon PA66 insulation strips. During the production process, the aluminum alloy profile is inserted into the toothed profile through a toothing machine, a strip threading machine and a strip assembly machine to form an insulation strip. The cavity of the PA66 insulation strip is filled with PE foam insulation material. After the window sash is assembled, the door and window hardware are installed.

[0033] The step S3 is specifically as follows: the spacer strip is made of a warm edge strip, a sealing frame is provided, connectors are eliminated, a spacer strip is directly bent into a continuous corner frame to form a mouth shape, and a corner penetration channel is eliminated.

[0034] The step S4 is specifically as follows:

[0035] 4.1 Filling with argon: After extracting the air, turn off the vacuum pump, open the argon valve, and inject argon into the insulating glass;

[0036] 4.2 Sealing: After the inflation is completed, close the argon valve and seal the inflation hole or pipe with a sealing layer to ensure that the argon does not leak. At the same time, ensure that there is bonding and sealing performance between the frame of the insulating glass and the sealing frame to prevent gas leakage.

[0037] Sunshade louvers are installed between the added glass and the original glass to facilitate sunshade operations.

[0038] In the present invention: a new type of heat-insulating material, high-strength polyurethane, is added to the indoor aluminum alloy part, which effectively reduces the heat transfer and eliminates the problem of "cold and hot bridges";

[0039] Thicken the glass layer or use vacuum hollow composite glass, and fill the hollow layer with inert gas.

[0040] Slow down the heat convection and heat conduction in the insulating glass, thereby reducing the thermal conductivity of the insulating glass as a whole, reducing the K value of the glass, and reducing the heat transfer coefficient of the insulating glass, so that the heat absorbed by the external glass cannot flow into the room, thereby improving the thermal insulation effect of doors and windows. The insulation strip effectively prevents the transfer of heat and effectively reduces the sound resonance effect;

[0041] The hollow layer of the glass prevents the outside air from entering the glass, and then the air is squeezed out by filling the hollow glass with argon gas, so as to effectively prevent the fogging inside the hollow glass; the glass periphery adopts high-performance heat-insulating and sound-insulating noodles to effectively block noise and effectively improve the sound insulation of doors and windows. The one-piece bending sealing strip has the advantages of good weather resistance, acid and alkali corrosion resistance, aging resistance, high elasticity, water resistance, oil resistance, sound insulation, heat preservation, and waterproof. It also has high bonding strength and is not easy to crack; the profile heat insulation strip is filled with polyurethane.
