Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of indoor door bodies in buildings, in particular to a door cover suitable for concrete aerated block walls. Background Art
[0002] Door frames can not only cover up the unevenness around the door opening and ensure its aesthetics, but also protect the wall from wear and tear and extend its service life. The most important point is that they can enhance the overall stability of the door body and prevent premature damage caused by swinging door leaves.
[0003] The door frame base widely used in the market is multi-layer board, which is popular because of its moderate price and easy processing. However, multi-layer board usually uses adhesives containing formaldehyde during the production process. Due to the limited ventilation conditions in the indoor environment, the use of multi-layer board poses a long-term threat to the health of residents.
[0004] Secondly, as a lightweight and porous building material, aerated concrete blocks have been widely used in the construction field due to their excellent thermal insulation properties and low cost. However, the mechanical properties of aerated concrete blocks, such as low strength and fragility, are relatively poor, making traditional nailing methods difficult to implement. When installing the door frame base, the nails cannot be firmly fixed to the aerated concrete block wall and are prone to loosening or falling off. This not only brings great inconvenience to construction, but also seriously affects the stability and service life of the door frame. In addition, the porous structure of the aerated concrete block wall also makes the wall easily damaged when subjected to external forces, further exacerbating the difficulty of door frame installation.

[0028] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.
[0029] like Figure 1-6 To address the issue of unstable door frames installed on concrete aerated block walls during interior decoration projects, the present application provides, in some illustrative embodiments, a door frame suitable for use on concrete aerated block walls, comprising: a door frame base and a door frame. The door frame base is installed on the door opening wall to provide basic support; the door frame is fixed to the door frame base to provide decoration and support the door.
[0030] The door frame base layer includes: a concrete lintel 1, a pressure-bearing layer 2 and several wooden installation parts 3.
[0031] A concrete lintel 1 is installed at the top of the door opening to distribute the weight of the door and doorframe, preventing the door frame from sinking or deforming due to gravity. Concrete lintel 1 is cast from high-strength concrete to ensure load-bearing capacity and stability. The length of concrete lintel 1 is greater than the width of the door opening, providing additional support area on both sides of the top of the door opening and enhancing the structural stability of the entire door frame. A pressure-bearing layer 2 is constructed of bricks—that is, stacked bricks—and is installed on top of concrete lintel 1.
[0032] Wooden beam mounting members 3 are installed on the side wall of the door opening, corresponding to the main load-bearing components of the door frame, such as the hinges and door locks. The door frame is fixed to the wall via wooden beam mounting members 3. Wooden beam mounting members 3 can be made of natural wood, replacing traditional artificial wood boards. This eliminates the need for a whole base board, is formaldehyde-free, and is safe and environmentally friendly. Furthermore, wooden beam mounting members 3 are only installed at the main load-bearing locations on the door frame, which is more material-efficient and environmentally friendly than paving the entire side wall of the door opening with multi-layer boards.
[0033] The timber mounting member 3 consists of horizontal timber beams 301 and vertical timber beams 302. Specifically, the design of the timber mounting member 3 utilizes both horizontal and vertical timber beams, forming a T-shaped cross-section. The horizontal timber beams 301 connect to the wall and provide a solid foundation for the vertical timber beams 302, ensuring the stability of the entire timber mounting member 3. The vertical timber beams 302 connect to the door frame, directly bearing the forces transmitted from the door frame.
[0034] The T-shaped structure of the wood beam mounting member 3 provides excellent support and fixation, ensuring that the door frame remains stable even when the door is frequently opened and closed. Due to the simple structure of the wood beam mounting member 3, construction workers can quickly install the horizontal wood beams 301 and vertical wood beams 302, improving construction efficiency. Moreover, compared to the method of laying multi-layer boards throughout the door, the T-shaped structure only installs wood beams in key locations, saving material costs.
[0035] This application utilizes the characteristics of the aerated block wall, that is, its mortar joint width is much larger than that of the traditional brick wall, and sets the horizontal wooden square 301 in the horizontal brick joint of the wall on the side of the door opening. The choice of this position fully utilizes the larger mortar joint width of the aerated block wall, so that the horizontal wooden square 301 can be firmly embedded in the wall without affecting the overall structure of the wall.
[0036] Installation Process: During the construction of the door opening wall, mortar 6 is spread between the aerated blocks. The horizontal timber 301 is then placed in the designated position and laid alongside the aerated blocks 4. During installation, ensure that the space between the top and bottom surfaces of the horizontal timber 301 and the aerated blocks 4 is filled with mortar. This not only ensures that the timber 301 forms a seamless connection with the wall but also secures it through the mortar's bonding after it cures. Once the mortar cures, the timber 301 is firmly attached to the wall, forming a solid support surface and providing a firm foundation for subsequent door frame installation.
[0037] The installation height of the horizontal wooden square 301 is consistent with or close to the height of the door hinge and door lock. The corresponding characteristics of the support points can ensure that the force of the door on the door frame can be evenly transmitted to the wall when opening and closing, thereby improving the stability and service life of the door.
[0038] The vertical wood planks 302 are arranged on the outer surface of the horizontal wood planks 301, and together with the horizontal wood planks 301, they form a stable frame to facilitate the installation and fixation of the door frame. Specifically, the vertical wood planks 302 are connected to the horizontal wood planks 301 with self-tapping screws. After the vertical wood planks 302 are installed, the opening is plastered to form the opening plaster layer 5.
[0039] The wooden square mounting member 3 not only solves the problem of directly fixing the door frame on the aerated block wall, but also improves the installation firmness of the door frame, while ensuring the simplicity of construction and the beauty of interior decoration.
[0040] The length of the horizontal wood planks 301 matches the width of the wall, and the outer surface of the horizontal wood planks 301 is flush with the outer surfaces of the aeration blocks 4 above and below the horizontal wood planks 301. This design ensures that the horizontal wood planks 301 span the entire width of the wall, providing uniform support along the entire side of the door opening. The outer surface of the horizontal wood planks 301 is flush with the side surface of the door opening wall, creating a smooth transition. This not only facilitates the fixing of the vertical wood planks 302, but also ensures that the vertical wood planks 302 are completely aligned with the wall, thereby improving stability.
[0041] The length of the vertical wood beams 302 is consistent with the width of the wall, ensuring that they span the entire width of the wall, thereby providing uniform support along the entire side of the door opening. The outer surface of the vertical wood beams 302 is coplanar with the surface of the plaster layer 5 at the opening, ensuring that the appearance of the side of the door opening remains consistent after the door frame is installed, without any unevenness, and improving overall stability. The inner surface of the vertical wood beams 302 aligns with the outer surfaces of the aerated blocks 4 located above and below the horizontal wood beams 301, making the entire support structure more stable and able to effectively distribute and bear the weight of the door frame and door body.
[0042] The close fit between the horizontal and vertical wooden beams 301 and 302 and other structural members makes the installation position of the door frame more accurate, helps to improve the installation quality of the entire door frame, and also ensures the flatness and decoration consistency of the side walls of the door opening.
[0043] An inclined surface 303 is provided on the inner side of the vertical wooden square 302, which is cut obliquely from the top surface to the inner side, so that the opening plaster layer 5 can extend toward the inner side of the vertical wooden square 302, avoiding the situation where the opening plaster layer 5 is broken or uneven at the edge of the wooden square, and a tighter combination is formed between the opening plaster layer 5 and the vertical wooden square 302, thereby enhancing the stability of the overall structure and reducing looseness or deformation caused by the gap between the wall and the wooden square.
[0044] The front and rear ends of the horizontal and vertical timbers 301 and 302 are each provided with interconnected channels 304. Specifically, the channels 304 are formed on the front and rear ends of the horizontal and vertical timbers 301 and 302, and the channels are interconnected to form a continuous passage. The size and shape of the channels 304 are designed to match the U-shaped mounting member 8, ensuring that the U-shaped mounting member 8 can be smoothly inserted and secured within the channels 304, thereby securing the frame base plate 7 to the timber mounting member 3.
[0045] The door frame includes: a frame base plate 7, a U-shaped mounting member 8, and a decorative frame body 9.
[0046] The frame base plate 7 has a notch 701 at a location corresponding to the channel 304, and a positioning groove 702 is formed on the outer surface of the frame base plate 7, which communicates with the notch 701. Accordingly, the dimensions of the notch 701 and positioning groove 702 match those of the channel 304. Channel 304, notch 701, and positioning groove 702 together form a U-shaped groove for accommodating the U-shaped mounting member 8. This structure simplifies the door frame installation process, eliminating the need for complex measurement and positioning. The position of the U-shaped mounting member 8 simply marks the position of the wooden mounting member 3, allowing a straight nail to be driven diagonally from the side. Furthermore, the U-shaped mounting member 8, secured within the U-shaped groove, provides solid support and positioning for the frame base plate 7, enhancing the overall stability of the door frame and reducing the possibility of displacement or misalignment.
[0047] When installing the frame base plate 7, at the location of the U-shaped mounting member 8, straight nails are driven obliquely from the side of the frame base plate 7 to fix the frame base plate 7, the U-shaped mounting member 8, and the vertical wood square 302. Then, the gap between the door frame and the door opening is filled with foam glue, and finally the decorative frame 9 is installed. The decorative frame 9 is set on the frame base plate 7 and covers the wood square mounting member 3, the frame base plate 7, and the U-shaped mounting member 8 to ensure the aesthetic appearance of the door frame exterior.
[0048] The U-shaped mounting member 8 includes: a positioning rod 801 and limiting side rods 802 arranged at both ends of the positioning rod 801. After the U-shaped mounting member 8 is fixed, the positioning rod 801 is located in the positioning groove 702, the front section of the limiting side rod 802 is located in the groove 304 opened on the horizontal wooden square 301, the middle section of the limiting side rod 802 is located in the groove 304 opened on the vertical wooden square 302, and the rear section of the limiting side rod 802 is located in the notch 701. The design of the U-shaped mounting member 8 realizes the fixation of the door frame in the vertical and front and back directions, and the oblique driving of the straight nails realizes the fixation in the horizontal direction, which improves the stability of the door frame. The structure of the U-shaped mounting member 8 makes the installation position of the door frame more precise, which helps to improve the overall installation quality of the door frame. The design of the U-shaped mounting member 8 simplifies the installation steps and improves construction efficiency.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
