Description

Technical Field

[0001] The utility model relates to the field of steel-wood armored doors, in particular to a steel-wood armored door with a door frame fully covered with wood. Background Art

[0002] Traditional steel-wood armored doors typically utilize a steel frame and wooden sash. The combination of a steel door frame and wooden sash lacks integrity and decorative qualities. While the steel door frame provides excellent anti-theft performance, its high thermal conductivity compromises energy conservation and environmental protection. The differences in material and appearance between the steel frame and wooden sash also compromise overall integrity. Therefore, the market urgently needs a steel-wood armored door that combines anti-theft and fireproofing with excellent decorative qualities and energy-saving and environmentally friendly features. Utility Model Content

[0003] The technical problem to be solved and the technical task to be proposed by this utility model are to improve and perfect the existing technical solutions and provide a steel-wood armored door with a door frame fully covered with wood, so as to improve the thermal insulation performance of the door frame and the integrity of the door frame and door leaf. To this end, this utility model adopts the following technical solutions.

[0004] A steel-wood armored door with a fully wood-clad door frame comprises a door frame and a door leaf. The door frame comprises a steel frame and a wooden frame wrapped around the steel frame. The door leaf has wooden front and rear surfaces, and an inner steel plate reinforcement layer and a fireproof material layer within the door leaf. The door frame and door leaf are connected by hinges. The steel frame wrapped in the wooden frame offers better thermal insulation than traditional pure steel frames. Both the door frame and door leaf are made of wood, providing improved integrity and consistency between the door frame and door leaf, and offering excellent decorative, energy-saving, and environmentally friendly features.

[0005] As a preferred technical approach, the wooden frame includes a front frame, a rear frame, main side frames, and a door stop frame. The front and rear frames are respectively located on the front and rear sides of the steel frame and fit in place with the steel frame. The main side frames fit in place with the door leaf side of the steel frame, and the main side frames and the rear frame mate with each other via a step. The door stop frame fits in place with the door leaf side of the main side frame, and the door stop frame mates with the front frame via a step. The split structure, which subdivides the wooden frame into multiple parts, allows each part to fit more tightly against the steel frame. Compared to a monolithic wooden frame, this reduces material procurement costs and manufacturing difficulty, and reduces the risk of deformation and cracking after long-term use due to varying internal material properties.

[0006] As a preferred technical measure, the front frame, rear frame, main side frame, door stop frame, and the front and rear wood panels of the door leaf are made of the same wood. This can achieve better integrity and consistency. After surface treatment, the appearance style remains consistent, which facilitates subsequent surface maintenance.

[0007] As a preferred technical approach, the door leaf is constructed with a wooden frame along the perimeter between the front and rear wooden planks. An inner steel reinforcement layer is installed on each side of the space between the two layers of wood and the wooden frame. A layer of fireproof material is placed between the two inner steel reinforcement layers. This effectively improves the overall strength and stability of the door leaf. It not only prevents deformation or breakage due to external forces but also maintains its flatness. The fireproof material layer placed between the two inner steel reinforcement layers significantly enhances the door leaf's fire resistance. This multi-layered structure provides the door leaf with enhanced sound insulation and thermal insulation.

[0008] As a preferred technical approach, the hinge is removably connected to the door leaf hinge plate and the door frame hinge plate via fixing screws. The door leaf hinge plate is removably connected to the wooden frame via multiple self-tapping screws, and the door frame hinge plate is secured via multiple long screws that pass through the main side frame and are removably connected to the steel frame. Providing removable hinge plates on the door frame and door leaf effectively enhances the structural strength of the hinge connection. Even if the hinge fixing screws are repeatedly removed during maintenance of the wooden door, the hinge plate's securement is not affected.

[0009] Beneficial effects: The steel frame is wrapped by a wooden frame, which has better thermal insulation performance than the traditional pure steel frame. The surface of the door frame and door leaf are made of the same wood, which has better integrity and consistency between the door frame and door leaf. It has good decorative and energy-saving and environmental protection characteristics, and is also convenient for subsequent surface treatment and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0013] like Figure 1The figure shows a schematic cross-section of one side of a steel-wood armored door with a fully wood-clad door frame. The steel-wood armored door comprises a door frame and door leaf. The door frame comprises a steel frame 1 and a wooden frame wrapped around the steel frame 1. The wooden frame comprises a front frame 2, a rear frame 3, a main side frame 4, and a door stop frame 5. The front frame 2 and rear frame 3 are respectively located on the front and rear sides of the steel frame 1 and are bonded to the steel frame 1. The main side frame 4 is bonded to the door leaf side of the steel frame 1, and the main side frame 4 and rear frame 3 are connected by a step. The door stop frame 5 is bonded to the door leaf side of the main side frame 4, and the door stop frame 5 is connected by a step to the front frame 2. The split structure that subdivides the wooden frame into multiple parts allows each part to fit more tightly to the steel frame 1. Compared to a monolithic wooden frame, the material procurement cost and manufacturing difficulty are lower, and the risk of deformation and cracking caused by different internal material properties after long-term use is also reduced. A buffer sealant strip 6 is bonded to the rear side of the door stop frame 5. The front and back surfaces of the door leaf are made of wooden boards 7. A wooden frame 8 is formed along the perimeter between the front and back layers of the wooden boards 7. An inner steel reinforcement layer 9 is provided on each of the front and back sides between the front and back layers of the wooden boards 7 and the wooden frame 8. A fireproofing material layer 10 is provided between the two inner steel reinforcement layers 9 to effectively maintain the flatness of the door leaf and improve its fireproofing performance. This multi-layered structure provides the door leaf with better sound insulation and thermal insulation. The door frame and door leaf are connected by hinges 11.

[0014] In order to achieve better integrity and consistency, the front frame 2, rear frame 3, main side frame 4 and door stop frame 5 are made of the same wood as the front and rear wood boards 7 of the door leaf. This can achieve better integrity and consistency. After surface treatment, the appearance style remains consistent, which facilitates subsequent surface maintenance.

[0015] In order to ensure that repeated removal of the hinge 11 does not affect the firmness of the connection structure, the hinge 11 is detachably connected and fixed to the door leaf hinge 11 fixing plate and the door frame hinge 11 fixing plate by fixing screws 12. The door leaf hinge 11 fixing plate is detachably connected and fixed to the wooden frame 8 by multiple self-tapping screws 13. The door frame hinge 11 fixing plate is fixed by multiple long screws 14. The long screws 14 pass through the main side frame 4 and are detachably connected and fixed to the steel frame 1. By providing a detachable hinge 11 fixing plate on the door frame and the door leaf, the structural strength of the hinge 11 connection can be effectively enhanced. Even if the hinge 11 is repeatedly removed when the wooden door needs maintenance, the fixing firmness of the hinge 11 fixing plate will not be affected.

[0016] The steel frame 1 is wrapped by the wooden frame 3. Compared with the traditional pure steel frame 1, the thermal insulation performance between the inside and outside of the door is better. The surface of the door frame and the door leaf are made of the same material wood board 7. The door frame and the door leaf have good integrity and consistency, which is convenient for subsequent surface treatment and maintenance, and has good integrity and energy-saving and environmental protection characteristics.

[0017] The steel-wood armored door with a fully wood-clad door frame shown above is a specific embodiment of the present invention, which has embodied the substantial characteristics and progress of the present invention.
