Description

Technical Field

[0001] This application belongs to the field of protective door technology, and in particular relates to a steel protective airtight door. Background Technology

[0002] A protective door is a door that can resist various shock waves or heavy object impacts. It is generally made of steel, but can also be made of other materials such as wood or concrete.

[0003] Patent CN215332445U discloses a lightweight protective door with external armor, comprising a steel skin, a carbon fiber composite laminate, a magnesium-aluminum alloy I-beam frame, a magnesium-aluminum alloy channel frame, and protective armor plates. The magnesium-aluminum alloy channel frame is connected end to end to form a rectangular frame. Several magnesium-aluminum alloy I-beam frames are arranged inside the frame, and the longitudinal magnesium-aluminum alloy I-beam frames and the transverse magnesium-aluminum alloy I-beam frames intersect to form an inner frame with a 6:3 ratio of longitudinal to transverse meshes. A buffer energy-absorbing layer is arranged inside the mesh. The outer side of the supporting frame is wrapped with a carbon fiber composite laminate, and a steel skin is arranged on the outer side of the carbon fiber composite laminate. The protective door is installed on the door frame by hinges, and a sealing strip is provided on the contact surface between the protective door and the door frame. Several protective armor plates and a door handle are arranged on the pressure-resistant surface of the protective door.

[0004] The aforementioned patent protects the door by setting up protective armor, but because the protective armor is a detachable structure, it cannot provide real-time protection and cannot cope with the occurrence of sudden accidents, so it needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a steel protective airtight door that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a steel protective airtight door, including a door frame, and further comprising:

[0007] The steel door body is rotatably installed inside the door frame;

[0008] The handle is located on one side of the steel door body;

[0009] A sealing structure is installed on the side of the steel door body that contacts the door frame;

[0010] The steel door body includes a steel outer frame, a reinforcing structure disposed within the steel outer frame, and a sealing top plate located for sealing the steel outer frame.

[0011] The aforementioned steel protective airtight door features a door frame fixedly mounted to the wall to support the door body, which is made of high-strength steel and rotatably mounted on the frame. A handle is installed on one side of the door body for easy operation. A sealing structure is installed on the side of the door body that contacts the door frame to ensure a tight seal when closed. The outer steel frame, as the main supporting structure of the door body, is also made of high-strength steel, providing excellent impact and pressure resistance. A reinforcing structure is installed inside the outer steel frame to further enhance the overall strength and stability of the door. A sealing top plate is located above the outer steel frame and is used to seal it after the reinforcing structure is installed.

[0012] Because the steel door body and its various components become a fixed and non-removable structure after processing, this protective airtight door can provide real-time protection and effectively respond to sudden accidents. Furthermore, the door body and outer frame made of high-strength steel, along with the internal reinforced structure, give this protective airtight door excellent impact and pressure resistance, effectively resisting external impacts and damage.

[0013] Furthermore, the reinforcing structure includes:

[0014] Install base plate;

[0015] Install the top plate;

[0016] A steel frame is installed between the mounting base plate and the mounting top plate and is plugged into both. The steel frame is located inside the steel outer frame, and a concrete pouring trough is also provided inside the steel frame.

[0017] Positioning protrusions are provided on both the bottom and top mounting plates, and a positioning groove is provided in the center;

[0018] Multiple reinforcing bars are installed between the mounting base plate and the mounting top plate, connecting to positioning grooves. The mounting base plate, located at the bottom of the reinforced structure, provides support for the bottom positioning protrusions and the steel frame. The mounting top plate, located at the top of the reinforced structure, corresponds to the mounting base plate, forming a closed frame structure with the mounting base plate and the steel frame. The steel frame is connected to the mounting base plate and mounting top plate via interlocking joints, facilitating their assembly and installation. A concrete pouring groove is also provided within the steel frame for pouring concrete; once the multiple reinforcing bars are installed on the positioning protrusions, they can be secured by pouring concrete.

[0019] Through the close cooperation and connection of the steel frame, mounting base plate, mounting top plate, steel bars, and concrete pouring, the reinforced structure can form a solid composite whole. After the reinforced structure is installed inside the steel outer frame, the overall steel door body has extremely high strength and stability, thus effectively resisting external impacts and damage, and ensuring the safety and reliability of the steel protective airtight door.

[0020] Furthermore, rock wool boards are also installed inside the steel outer frame. The rock wool boards are installed on both sides of the steel frame, and the sealing top plates of the steel outer frame are connected by welding.

[0021] Rock wool board is a high-quality thermal insulation, heat insulation, and fireproof material. It possesses excellent high-temperature resistance, low thermal conductivity, and superior fire resistance, effectively preventing heat transfer and the spread of flames. By installing rock wool boards inside a steel frame and placing them on both sides of the frame, not only is the door's thermal insulation performance enhanced, but its fire resistance is also improved. Simultaneously, a sealing top plate is installed above the steel frame to seal it and protect the internal reinforced structure. The sealing top plate is welded to the steel frame, ensuring a tight and secure connection, further enhancing the overall structural stability of the door and improving its impact and pressure resistance.

[0022] Furthermore, the sealing structure includes a sealing edge disposed on the steel door body, and an inner frame disposed on the door frame that contacts the sealing edge.

[0023] The sealing edge is installed on the steel door body. By making close contact with the inner frame on the door frame when closed, it forms an effective seal, effectively preventing the intrusion of external gases, liquids or solid substances. At the same time, the sealing edge is made of fire-resistant elastic material.

[0024] Furthermore, an automatic door closer is also provided on the door frame, and the other end of the automatic door closer is connected to the steel door body.

[0025] Automatic door closers can automatically pull the door back and close it after it has been opened, eliminating the need for manual operation and improving both convenience and security. One end of the automatic door closer is fixed to the door frame, and the other end is connected to the steel door body, typically using bolts, screws, or other fasteners. The automatic door closer used here is a commercially available model; its internal structure will not be described in detail.

[0026] Furthermore, LED lights are installed on the door frame, with LED lights installed on both sides of the door frame.

[0027] LED lights provide illumination on both sides of the door frame, making it easier for users to use the steel security door in low-light conditions, and facilitating key insertion or handle gripping. The LED lights are also powered by electrical wires and can provide direction for people at a distance, guiding them to the security door.

[0028] The beneficial effects of this application are:

[0029] 1. The steel door body and its various components of this application become a fixed and non-removable structure after processing. Therefore, this protective airtight door can provide protection in real time and effectively cope with the occurrence of sudden accidents. Moreover, the door body and outer frame made of high-strength steel, as well as the internal reinforced structure, give the protective airtight door of this application good impact and pressure resistance, and can effectively resist external impacts and damage.

[0030] 2. Through the close cooperation and connection of the steel frame, installation base plate, installation top plate, steel bars and concrete pouring, the reinforced structure can form a solid composite whole. After the reinforced structure is installed in the steel outer frame, the whole steel door body has extremely high strength and stability, thus effectively resisting external impacts and damage, ensuring the safety and reliability of the steel protective airtight door.

[0031] 3. By installing rock wool boards inside the steel frame and placing them on both sides of the steel frame, not only can the heat insulation performance of the door be enhanced, but its fire resistance can also be improved. Attached Figure Description
