Description

Technical Field

[0001] This utility model relates to the field of old window renovation technology, specifically to a non-dismantling old window renovation structure. Background Technology

[0002] Windows and doors are weak links in building insulation. Window renovation, mainly in the form of energy-saving retrofitting of old windows, has begun in China. Window renovation is an important development direction for the country to explore sustainable models for energy-saving retrofitting of existing buildings. In the process of retrofitting old windows, the market often removes the original window and door frames and replaces the entire window. However, this damages the already decorated and decorated window and door openings and partially affects the main structure. Therefore, it is necessary for the market to explore a way to quickly replace windows and doors without damaging the existing openings.

[0003] The replacement of doors and windows is becoming increasingly common, mainly for the following reasons: 1. The performance and functionality of existing old windows are gradually becoming outdated and can no longer meet the requirements of use, so owners take the initiative to upgrade and replace them; 2. In some old buildings, especially public buildings with high energy consumption, the energy-saving performance of doors and windows can no longer meet the requirements of current standards, and the construction authorities have mandated energy-saving renovations of existing buildings.

[0004] However, when renovating old windows, the original doors and windows need to be removed and replaced with new ones. The workload and difficulty of removal are the main challenges in window and door renovation. Since the window frames are fixed to the wall, removing the window frames increases the difficulty and workload of construction and also results in a significant waste of resources. In addition, if the window frames are not removed carefully, the main structure can be damaged, thereby affecting the installation of new doors and windows and the overall strength and stability of the window, which is a major problem in old window renovation. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes a non-disassembly-renovation structure for old windows, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] A non-removable old window renovation structure includes an old window frame, the bottom of which is provided with a snap-fit ​​base to be fixed in the wall, and a new window frame is provided above the old window frame. At least one fixing structure is provided between the old window frame and the new window frame.

[0007] The new window frame includes an inner frame and an outer frame. The inner frame is fitted to the old window frame. A pad is provided between the old window frame and the outer frame at the cavity position corresponding to the outside of the fixed structure. The inner side of the new window frame is provided with an inner sealing plate extending vertically downward. A first foaming strip is provided between the bottom of the inner sealing plate and the wall.

[0008] As an improvement to the above solution, the outer side of the outer frame is provided with a vertically downward extending outer sealing plate, the top of the outer sealing plate is attached to the bottom of the outer frame, and a second foaming strip is provided between the bottom of the outer sealing plate and the wall.

[0009] As an improvement to the above solution, a first fixing structure is provided between the inner frame and the old window frame, and a second fixing structure is provided between the outer sealing plate and the bottom of the outer frame. Both the first fixing structure and the second fixing structure are fixing screws.

[0010] As an improvement to the above solution, the inner frame and the inner sealing plate are separate structures. The inner frame has a clamp-shaped card interface on the side facing the room, and the top side of the inner sealing plate has a card-connecting part that matches the shape of the card interface.

[0011] As an improvement to the above solution, the old window frame has an L-shaped PVC plate on the side facing the interior and the end face that fits with the new window frame, and the fixing structure passes through the PVC plate to connect the old window frame and the new window frame.

[0012] The beneficial effects of this utility model are as follows: The protruding parts of the old window frame are cut off, and the new window frame is directly installed on the old window frame using a fixing structure, eliminating the need to remove the old window frame from the wall and preventing damage to the wall structure. The new window frame, along with the sealing plate, completely covers the original old window frame, improving the installation efficiency and quality. The inner and outer sealing plates cover and decorate the joint gap between the new and old window frames. The pads fill the structural gap between the new and old window frames, making the new window frame more stable and providing better load-bearing capacity when installed on the old window frame.
