[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] A method for installing aluminum door frames, the method comprising the following steps:
[0039] (1) Door frame fixing: Clean the door opening, fix the aluminum door frame in the door opening, and fill the gap between the aluminum door frame and the door opening with expanding foam;
[0040] (2) First reinforcement: After grinding and cleaning the wall surface of the aluminum door frame and the door opening, use a scraper to evenly apply putty paste to the wall surface as a base to obtain a smooth aluminum door frame and the wall surface connected to the door opening; before the base putty dries, lay the joint tape at the joint between the door opening and the aluminum door frame, and use a scraper to press the joint tape tightly onto the putty paste;
[0041] (3) Anti-corrosion treatment: After the putty paste with the seam tape is completely dry, use a roller brush to evenly apply the anti-alkali slaze water to the wall surface of the aluminum door frame and the door opening.
[0042] (4) Second reinforcement: After the alkali-resistant slaze water has dried completely, use a scraper to evenly apply the putty paste to the wall surface, and lay the alkali-resistant fiberglass mesh on the putty paste. Press it firmly with a scraper to obtain a smooth wall surface without air bubbles between the alkali-resistant fiberglass mesh and the putty paste.
[0043] (5) Filling uneven surfaces: After the putty paste with glass fiber alkali-resistant mesh cloth is completely dry, use a scraper to evenly apply the putty paste to the wall surface to complete the first putty paste leveling and obtain a smooth wall surface.
[0044] (6) Second repair: After the putty paste from the first putty application has dried completely, use a scraper to evenly apply the putty paste to the wall surface to complete the second putty application and obtain a smooth wall surface.
[0045] (7) Decoration processing: After the putty paste that has been smoothed by the second putty is completely dry, clean the dust, oil stains and debris on the wall surface, and then use a roller or brush to evenly apply the primer to the wall surface. On the wall surface with primer, use a roller or brush to evenly apply the topcoat to the wall surface.
[0046] Alternatively, after the second coat of putty has dried completely, clean the wall surface of dust, oil, and debris before applying wallpaper or wall coverings.
[0047] Most interior door frames commonly used in the market consist of a frame panel and a trim panel. During installation, the frame panel is fixed to the side wall inside the doorway, and then the trim panel is installed on the frame panel to finish the wall surface. In this finishing process, expanding foam is usually used to fill the gaps in the wall. However, traditional door frames are made of wood, and the natural shrinkage of wood often leads to cracks at the finish. Furthermore, the interface between the door frame and wall coverings, wallpaper, or paint is also prone to cracking. These problems not only greatly affect the lifespan of the door frame but also seriously impact its decorative effect.Therefore, this invention proposes an aluminum door frame installation method: First, door frame fixing: After cleaning the doorway, fix the assembled aluminum door frame in the doorway, and fill the gap between the aluminum door frame and the doorway with expanding foam to complete the positioning and installation between the aluminum door frame and the doorway; Second, reinforcement: Grind and clean the surface of the aluminum door frame and the wall around the doorway, and use a scraper to evenly apply the prepared putty paste to the wall surface as a base coat. This process is to repair unevenness and imperfections on the surface of the aluminum door frame and the wall surface around the doorway, making it smooth and even, and providing a good foundation for subsequent decoration processes, forming a smooth surface on the wall. First, apply a strong layer of putty. Then, while the base putty is still wet, lay joint tape over the joint between the aluminum door frame and the door opening, pressing it firmly onto the putty. This enhances the strength and stability of the joint, providing extra support and protection against cracking caused by thermal expansion and contraction due to temperature changes and opening and closing the door. Second, after the putty has dried completely, use a roller to evenly apply anti-alkali slag to the surface of the aluminum door frame and the wall opening. This prevents corrosion, oxidation, or other damage to the aluminum door frame surface, resists alkaline erosion, maintains the integrity of the coating, and the anti-alkali slag can cover uneven surfaces and fill gaps. It boasts strong adhesion and durability, while also featuring a waterproof layer to prevent wall leaks and dampness. This further strengthens the connection between the tear-resistant joint tape and the aluminum door frame. The fourth step, a second reinforcement, involves applying putty evenly to the wall surface with a scraper after the alkali-resistant slurry has dried completely. Then, the alkali-resistant fiberglass mesh is laid on top of the putty and compacted with the scraper. This results in a smooth, bubble-free wall surface between the fiberglass mesh and the putty, reinforcing the adhesion between the aluminum door frame and the wall. This prevents damage to the door from external forces and enhances the flexibility and deformability of the aluminum door frame and the wall, filling any imperfections at the joints. Smoothing makes the surface smoother and can hide imperfections at the joints, providing a more aesthetically pleasing decorative effect; filling unevenness on the wall surface to achieve a flat and smooth state; the fifth step, leveling unevenness, and the sixth step, secondary repair, therefore, after the putty with fiberglass alkali-resistant mesh cloth is completely dry, two layers of putty are applied. The first layer of putty leveling fills surface defects such as grooves, cracks, and protrusions, ensuring the adhesion and appearance of subsequent coatings or decorative materials. The second layer of putty leveling further repairs and fills uneven areas, making the wall surface smoother. This ensures a more beautiful final coating effect and facilitates subsequent paint application. In addition, the second application of putty can repair small cracks and air bubbles that may have occurred during the first application of putty, improving the quality and durability of the wall. The seventh step is decoration and finishing. After the two applications of putty are completed and the putty is completely dry, apply primer and topcoat to the wall or apply wallpaper or wall coverings to protect the wall from dirt and scratches, making the wall more beautiful and extending the service life and decorative effect of the door frame.
[0048] Furthermore, the putty paste used in steps (2) to (6) is made by mixing indoor putty powder and water in a ratio of 1:0.5, and the drying time of the putty paste is at least 24 hours.
[0049] To further explain, pour an appropriate amount of interior putty powder into a clean container, and gradually add an appropriate amount of water in a 1:0.5 ratio. Stir well with an electric mixer and then use a putty scraper to apply a small amount. The putty should be firm enough to not flow but easily spread on the aluminum door frame substrate. It is then ready for use. It should be noted that a 1:0.3 ratio of interior putty powder to water will result in a highly viscous putty paste that is difficult to apply and prone to peeling after drying; a 1:1 ratio will be too thin and lack adhesion. A 1:0.5 ratio ensures that the putty paste does not drip or seep into the aluminum door frame substrate during application, resulting in better adhesion. In addition, interior putty powder has higher strength than ordinary putty powder, which can better adhere the aluminum door frame to the wall surface and prevent it from falling off the aluminum door frame surface. Also, because interior putty powder has better adhesion than ordinary putty powder, it can better adhere the aluminum door frame to the wall surface.
[0050] Furthermore, if the first and second reinforcement steps are reversed, it will affect the adhesion of the putty paste and cause the plaster layer on the wall to peel off; and each step change will cause quality problems, such as uneven walls or pits, affecting the final construction quality.
[0051] Furthermore, the thickness of the putty paste applied in step (2) is in the range of 0.2-0.5 mm.
[0052] To further explain, in step (2), the putty paste is first applied to an aluminum door frame and the wall surface of the door opening as a base, with a thickness between 0.2-0.5mm, to fill the depressions and pits in the wall surface and make the surface smooth.
[0053] Furthermore, in step (2), the width of the seam tape ranges from 8cm to 10cm, and the length is consistent with the height of the aluminum door frame. The seam tape is made of Dacron fabric.
[0054] To further explain, the width of the seam tape in step (2) is set to 8cm-10cm, and the length is the same as the height of the aluminum door frame, so as to cover the gap between the aluminum door frame and the door opening. The seam tape made of Dacron fabric has the characteristics of high tensile strength and support, stronger adhesion, no cracking and no bubbling.
[0055] Furthermore, in step (4), the thickness of the putty paste is in the range of 0.2mm-0.5mm, the width of the glass fiber alkali-resistant mesh is in the range of 10cm-12cm, and the length is consistent with the height of the door frame.
[0056] To further explain, after applying a 0.2mm-0.5mm thick layer of putty paste to the wall, a fiberglass alkali-resistant mesh cloth with a width of 10cm-12cm and a length consistent with the height of the aluminum door frame is laid on the putty paste. The 0.2mm-0.5mm thick putty paste can tightly adhere and compact the fiberglass alkali-resistant mesh cloth, so a thicker layer of putty paste is not required.
[0057] Furthermore, in step (5), the thickness of the putty paste applied during the first smoothing process ranges from 2mm to 3mm.
[0058] To further explain, after the joint tape and the alkali-resistant fiberglass mesh are sequentially applied to the joint between the aluminum door frame and the door opening, the wall surface is first smoothed with putty. The putty paste applied for the first smoothing is used to fill the unevenness of the wall surface and make it flat and smooth. The thickness of the paste is set within the range of 2mm-3mm. The thickness should not be too thick to avoid affecting the peeling of the door frame and the putty or causing cracking.
[0059] Furthermore, in step (6), the thickness of the putty paste applied for the second putty application ranges from 0.8mm to 1.5mm.
[0060] To further explain, the second application of putty makes the wall surface smoother, ensuring a more aesthetically pleasing final finish and facilitating subsequent paint application. Furthermore, the second application can repair any small cracks or air bubbles that may have appeared during the first application, improving the wall's quality and durability. Therefore, the thickness should be set between 0.8mm and 1.5mm to avoid excessive thickness that could cause the door to peel off from the substrate or result in cracking.
[0061] Furthermore, in step (5), when the first putty is applied, a scraper is used to apply it horizontally along the wall to obtain a smooth wall surface. After the putty paste from the first application is completely dry, the wall surface is sanded with 360# sandpaper.
[0062] In step (6), when the putty is applied for the second time, a scraper is used to apply it vertically along the wall to obtain a smooth wall surface. After the putty paste applied for the second time has dried completely, the wall surface is sanded with 360# sandpaper.
[0063] To further explain, when applying the first coat of putty, use a scraper to apply it horizontally along the wall to create a smooth surface. After the first coat of putty has dried completely, sand the wall with 360# sandpaper. When applying the second coat of putty, use a scraper to apply it vertically along the wall to create a smooth surface. After the second coat of putty has dried completely, sand the wall with 360# sandpaper. The scraping directions are perpendicular to each other to further fill in any unevenness on the wall surface, making it flat and smooth. This ensures a more aesthetically pleasing final finish. In addition, sanding the wall with 360# sandpaper twice ensures that there are no obvious uneven areas on the surface, making the wall surface even smoother.
[0064] Furthermore, the thickness of the topcoat in step (7) is 0.5mm-2mm; after the topcoat dries in 3-5 days, the second coat of topcoat is applied, and the operation method is the same as the first time.
[0065] To further explain, after applying the primer, two coats of topcoat are applied. The topcoat prevents oxidation and corrosion of the wall, and two coats enhance the gloss and scratch resistance of the paint, extending its lifespan, improving the wall's appearance, increasing gloss, color vibrancy, and visual appeal, making it more attractive. Furthermore, the thickness of each coat of topcoat should be between 0.5mm and 2mm, and must be applied according to the specified thickness.

[0067] (1) Prepare installation tools;
[0068] (2) Install the aluminum door frame according to the aluminum door frame installation construction method described above;
[0069] (3) Install hinges on one side of the aluminum frame, connect the door to the aluminum frame through the hinges, and adjust the door gap;

These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
