Description

Technical Field

[0001] The utility model relates to the technical field of building interior doors, in particular to a novel block wall door cover structure. Background Art

[0002] The function of a door frame is not only to cover the unevenness around the door opening and ensure the overall appearance, but also to effectively protect the wall from wear and tear, thus extending its service life. Most importantly, the door frame can improve the overall stability of the door body and prevent premature damage caused by door leaf swinging.

[0003] Currently, the most commonly used door frame base material on the market is multi-layer board, which is popular for its reasonable price and easy processing. However, the production process of multi-layer board often uses adhesives containing formaldehyde. Due to limited indoor ventilation, long-term use of this material may pose a health risk to residents. In addition, block walls, which are built with hard bricks, make traditional nailing methods difficult to apply. When securing door frames, harder nails are required to apply force, which can easily damage the door frame or cause the nails to slip or bend. After the fixing is completed, additional steps are required to cover the fixing area, which increases the complexity of installation. Summary of the Invention

[0004] To address the aforementioned technical issues, the present invention provides a novel block wall door frame structure. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is provided below. This summary is not intended to be a comprehensive review, identify key or important components, or delineate the scope of protection for these embodiments. Its sole purpose is to present some concepts in a simplified form, serving as a prelude to the detailed description that follows.

[0005] The utility model adopts the following technical solutions:

[0006] Provided is a novel block wall door cover structure, comprising: a door opening base layer and a door cover assembly connected to the door opening base layer;

[0007] The door opening base layer includes: a plurality of wooden square mounting members, and the wooden square mounting members are composed of a structural adhesive layer and a trapezoidal wooden strip; the wider side surface of the trapezoidal wooden strip is bonded to the outer end surface of the door opening brick through the structural adhesive layer, and a foam adhesive layer is provided between the narrower side surface of the trapezoidal wooden strip and the door cover assembly;

[0008] The door frame assembly includes: a door frame and a door frame line. Installation grooves are provided on both sides of the door frame. Installation nails are nailed into the door frame, the foam layer and the trapezoidal wooden strips in sequence from the notches of the installation grooves. An inlay block adapted to the installation groove is provided on the inner side of the door frame line.

[0009] Furthermore, the door opening base layer also includes: a concrete lintel; the concrete lintel is arranged at the top of the door opening, and the length of the concrete lintel is greater than the width of the door opening.

[0010] Furthermore, the width of the wider side surface of the trapezoidal wooden strip is greater than the height of the door opening bricks to form an oblique angle, and the formed oblique angle is located in the mortar between the door opening bricks.

[0011] Furthermore, the narrower side of the trapezoidal wooden strip protrudes from the side wall of the door opening, and the thickness of the protruding part is consistent with the thickness of the plaster layer of the opening, so that the surface of the narrower side of the trapezoidal wooden strip and the surface of the plaster layer of the opening are located on the same plane.

[0012] Furthermore, the length of the trapezoidal wooden strips is consistent with the width of the wall.

[0013] Furthermore, a sunken groove is opened on one side of the groove wall of the installation groove close to the trapezoidal wooden strip, and a reinforcement ring is set in the sunken groove. The installation nails are nailed into the door frame, the foam layer and the trapezoidal wooden strip in sequence from the notch of the installation groove through the bottom of the sunken groove.

[0014] Furthermore, the door cover assembly also includes: an L-shaped plug-in, which is arranged in the installation groove, and one of the plates of the L-shaped plug-in is fitted with a side wall of the installation groove close to the trapezoidal wooden strip, and the other plate is fitted with the bottom of the installation groove.

[0015] Furthermore, a guide plate is provided on the L-shaped plug-in unit, and an inner side surface of the guide plate and an outer side surface of the insert are both provided with inclined surfaces.

[0016] The beneficial effects brought by the utility model are:

[0017] 1. Use the wooden mounting piece as the door frame base, and use the structural adhesive layer to elastically bond with the door opening bricks. Use mounting nails to fix the door frame to the wooden mounting piece. The installation method is simple, and the mounting nails can be driven in at an angle. While ensuring the connection is firm, the fixing point is hidden within the door frame, which is beautiful and simplifies the installation process.

[0018] 2. The structural design is more reasonable. The trapezoidal wooden strips only need to be installed in the main stress-bearing positions such as hinges and door locks, which can effectively resist the vibration caused by long-term opening and closing of wooden doors. Compared with the method of covering the sides of the opening with multi-layer boards, it is more material-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] like Figure 1-4 In some illustrative embodiments, a novel block wall door frame structure is provided, comprising: a door opening base layer and a door frame assembly. The door opening base layer is disposed on the door opening wall for basic support and positioning; the door frame assembly is fixed to the door opening base layer, i.e., the door frame assembly is connected to the wall through the door opening base layer, providing decoration and supporting the door body.

[0026] The door opening base layer includes: a concrete lintel 1 and several wooden installation parts 2.

[0027] 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, enhancing the structural stability of the entire door frame.

[0028] Wooden beam mounting members 2 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 assembly is fixed to the wall through wooden beam mounting members 2. Wooden beam mounting members 2 are composed of a structural adhesive layer 201 and a trapezoidal wooden strip 202. The trapezoidal wooden strip 202 is a wooden strip with a trapezoidal cross-section. The trapezoidal wooden strip 202 can be made of natural wooden beams, replacing traditional artificial wood boards. This eliminates the need for a whole base board, is formaldehyde-free, and is safe and environmentally friendly. Furthermore, the trapezoidal wooden strip 202 is only installed at the main load-bearing locations of the door frame assembly. Compared to the practice of paving the side wall of the door opening with multi-layer boards, it is more material-saving and environmentally friendly.

[0029] The wider side of the trapezoidal strip 202 is bonded to the outer end of the door opening brick 3 via a structural adhesive layer 201. A foam adhesive layer 4 is placed between the narrower side of the strip 202 and the door frame assembly. When constructing the wall at the door opening, a gap is left in the bricks at the height corresponding to the door hinge and door lock. The reserved gap allows the trapezoidal strip 202 to fit neatly into the gap, ensuring the stability of the door frame assembly and making the installation process more precise and convenient.

[0030] In the trapezoidal wooden strips 202, the wider side surface is evenly coated with a structural adhesive layer 201, allowing the trapezoidal wooden strips 202 to be firmly bonded to the outer end surface of the door opening brick 3. This not only provides sufficient support to ensure a tight connection between the trapezoidal wooden strips 202 and the door opening wall, but also the elastic connection between the trapezoidal wooden strips 202 and the door opening brick 3 can effectively resist the vibration caused by the long-term opening and closing of the wooden door, thereby improving the installation security of the door frame. On the other hand, the narrower side surface of the trapezoidal wooden strips 202 is used for connecting to the door frame assembly, and a layer of foamed adhesive layer 4 is provided between them. The function of the foamed adhesive layer 4 is to fill the gap between the trapezoidal wooden strips 202 and the door frame assembly to improve the sealing performance. It also plays a certain buffering role, reducing the vibration and noise caused by the opening and closing of the door.

[0031] The trapezoidal wooden strip 202 has inclined surfaces on both the upper and lower surfaces, forming a specific trapezoidal cross-section. In this trapezoidal structure, the width D1 of the wider side surface is greater than the height H of the door opening brick 3, thereby forming an oblique angle 203 between the trapezoidal wooden strip 202 and the door opening brick 3. When the trapezoidal wooden strip 202 is installed in place, the oblique angle 203 forms an embedded and interlocking structure with the surrounding cement mortar 5. This structure utilizes the principle of inclined planes, so that the connection between the wooden strip and the wall not only relies on the bonding force of the structural adhesive layer 201, but also increases the effect of mechanical interlocking. In this application, the design of the trapezoidal wooden strip 202 fully considers the close connection with the door opening brick 3, which not only improves the stability of the trapezoidal wooden strip 202, but also greatly reduces the risk of the wooden strip loosening or falling off due to external forces, thereby improving the overall firmness.

[0032] The length of the trapezoidal wooden strip 202 is consistent with the width of the wall, specifically, the same as the width of the wall before plastering. Therefore, the trapezoidal wooden strip 202 can span the entire width of the wall, thereby providing uniform support along the entire side of the door opening. The narrower side of the trapezoidal wooden strip 202 protrudes from the side wall of the door opening, and the thickness of the protruding portion is consistent with the thickness D2 of the plaster layer 6 of the opening, so that the surface of the narrower side of the trapezoidal wooden strip 202 and the surface of the plaster layer 6 of the opening are located on the same plane. After the brick wall surface and the opening are plastered, the upper and lower oblique edges of the trapezoidal wooden strip 202 are tightly wrapped by the plaster layer 6 of the opening. The surface of the plaster layer 6 of the opening is flush with the short side of the trapezoidal wooden strip 202, without any height difference, thus ensuring a smooth transition at the edge of the door opening. The front and rear ends of the trapezoidal wooden strip 202 are covered by the wall plaster layer 7, effectively concealing the joint between the trapezoidal wooden strip 202 and the wall.

[0033] The upper and lower bevels of the trapezoidal strips 202 are tightly wrapped by the opening plaster layer 6, enhancing the structural stability between the strips 202 and the wall and reducing the risk of the strips 202 loosening or falling due to external forces. Because the length of the strips 202 matches the width of the wall and the thickness of the protruding portion matches the thickness of the plaster layer, they not only provide uniform support for the entire side of the door opening but also provide convenience for construction workers, making the installation process faster and more accurate.

[0034] The door cover assembly includes: a door cover frame 8 and a door cover line 9.

[0035] Mounting slots 801 are defined on both sides of the door frame 8. During installation, mounting nails 10 are inserted through the notches of the mounting slots 801, through the door frame 8, through the foam layer 4, and finally, diagonally into the trapezoidal wood strips 202. This installation method ensures a secure connection between the door frame 8 and the trapezoidal wood strips 202 while also allowing the foam layer 4 to effectively fill the gaps, enhancing sealing and stability.

[0036] The inner side of the door frame 9 is provided with an insert 901 that is adapted to the installation groove 801. During installation, the door frame 9 is placed on the surface of the door frame 8, ensuring that the insert 901 on its inner side is aligned with the installation groove 801. Then, with appropriate pressure, the insert 901 of the door frame 9 is firmly embedded in the installation groove 801, making the door frame 9 and the door frame 8 become a whole. Therefore, the door frame 9 not only serves a decorative purpose, but also enhances the overall structural strength of the door frame. It also allows the fixing point of the installation nail 10 to be hidden inside the door frame 9, which is beautiful and simplifies the installation steps, improves installation efficiency, and ensures the stability of the door frame.

[0037] A recessed groove 802 is formed on one side of the mounting groove 801 near the trapezoidal wood strip 202, and a reinforcement ring 803 is provided in the recessed groove 802. The mounting nail 10 is sequentially nailed into the door frame 8, the foam rubber layer 4, and the trapezoidal wood strip 202 from the notch of the mounting groove 801 through the bottom of the recessed groove 802. The recessed groove 802 serves as a clearance, facilitating adjustment of the nailing angle when nailing the mounting nail 10, and facilitating positioning the mounting nail 10 to a suitable position for nailing. In this structure, the reinforcement ring 803 can provide a more stable support point, facilitating more effective fixing of the mounting nail 10 to the door frame assembly, and also serves to increase strength, preventing damage to other structures when nailing the mounting nail 10. The tail end of the mounting nail 10 can be bent or buckled on the reinforcement ring 803, thereby generating additional fixing force on the reinforcement ring 803.

[0038] The door cover assembly also includes an L-shaped insert 11, which features two perpendicular panels. L-shaped insert 11 is positioned within mounting slot 801, with one panel aligning with the side wall of mounting slot 801 near the trapezoidal wood strip 202, and the other panel aligning with the bottom of mounting slot 801. This design allows L-shaped insert 11 to be securely fastened within mounting slot 801, increasing its strength while also providing a concealed fixing point for mounting nail 10, preventing the head of the nail from being exposed.

[0039] A guide plate 12 is mounted on the L-shaped insert 11. Both the inner surface of the guide plate 12 and the outer surface of the insert 901 are provided with inclined surfaces. Once the door molding 9 is mounted on the door frame 8, the insert 901 enters the mounting groove 801 and engages with the L-shaped insert 11 and guide plate 12. Due to the inclined surfaces on the guide plate 12 and insert 901, once the door molding 9 is secured to the door frame 8, the insert 901 slides more easily into the mounting groove 801 and securely engages with the L-shaped insert 11 and guide plate 12, ensuring accurate positioning and stable fixation.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
