Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a fire door with fireproof strips on the door leaf. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are usually installed on fire-resistant partitions with a certain degree of fire resistance, such as fire compartments, evacuation stairwells, and vertical shafts, to ensure the evacuation of personnel in the event of an accident.

[0003] Some existing fire doors only have fire-resistant strips on the door frame, but not on the door leaf. This design results in insufficient airtightness between the door frame and the door leaf, which cannot effectively prevent fire and smoke from escaping through the gaps between the door frame and the door leaf. As a result, the overall fire resistance of the fire door is not high and the fire resistance time is not long. Therefore, in order to address the above problems, a fire door with fire-resistant strips on the door leaf is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fire door with a fireproof strip on the door leaf, so as to solve the problem that the fireproof strip of some existing fire doors is only set on the door frame, but there is no fireproof strip on the door leaf. This design structure results in insufficient airtightness of the door frame and door leaf.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fireproof door with a fireproof strip on the door leaf includes a door frame and a door leaf. The door leaf is rotatably connected to the inner side of the door frame via a hinge. The door leaf consists of a door panel body and an outer covering plate. The outer covering plate covers the outer side of the door panel body. The right half of the door leaf is provided with a handle and a door lock. The upper half of the door frame and the door leaf are provided with a door closer. An airtight strip is fixedly connected to the first groove of the door frame. Fireproof and smokeproof strips are fixedly connected to the second groove of the door panel body and the third groove of the outer covering plate.

[0007] Preferably, the inner side of the door frame is provided with a first groove, the upper and lower sides of the door panel body are provided with horizontally distributed second grooves, and the left and right sides of the outer cover plate are provided with vertically distributed third grooves.

[0008] Preferably, the first groove of the door frame is a rectangular frame structure, the first groove of the door frame is located on the rear side of the door leaf, the airtight strip is bent to form a rectangular frame, and the airtight strip is attached to the rear side edge of the door leaf.

[0009] Preferably, the second groove of the door panel body and the third groove of the outer cover plate form a rectangular frame structure, the fireproof and smokeproof strip is bent to form a rectangular frame, and the fireproof and smokeproof strip is attached to the inner side of the door frame.

[0010] Preferably, the door panel body is formed by stamping a rectangular steel plate, and the outer buckle plate covers the front, back, left and right sides of the door panel body. The outer buckle plate is formed by two steel plates snapped together.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by incorporating an airtight strip and a fireproof and smoke-proof strip, the device can fill the gaps between the door frame and the door leaf. This dual fireproofing measure more effectively prevents the escape of fire and smoke. At the same time, the airtight strip can absorb shock and provide sound insulation, while the fireproof and smoke-proof strip can isolate flames and smoke in the event of a fire. The device has sufficient airtightness to effectively prevent fire and smoke from escaping from the gaps between the door frame and the door leaf, thereby improving the overall fire resistance of the fire door and providing a longer fire resistance time.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A fireproof door with a fireproof strip on the door leaf includes a door frame 1 and a door leaf 2. The door leaf 2 is rotatably connected to the inner side of the door frame 1 via a hinge 3. The door leaf 2 is composed of a door panel body 21 and an outer covering plate 22. The outer covering plate 22 covers the outer side of the door panel body 21. The right half of the door leaf 2 is provided with a handle 4 and a door lock 5. The upper half of the door frame 1 and the door leaf 2 are provided with a door closer 6. An airtight strip 7 is fixedly connected in the first groove of the door frame 1. Fireproof and smokeproof strips 8 are fixedly connected in the second groove of the door panel body 21 and the third groove of the outer covering plate 22.

[0024] The inner side of the door frame 1 has a first groove, and the upper and lower sides of the door panel body 21 have horizontally distributed second grooves. The left and right sides of the outer cover plate 22 have vertically distributed third grooves. The door frame 1 is fixed with the airtight strip 7 through the first groove, and the door leaf 2 is fixed with the fireproof and smokeproof strip 8 through the second and third grooves. The first groove of the door frame 1 is a rectangular frame structure, located on the rear side of the door leaf 2. The airtight strip 7 is bent to form a rectangular frame, and the airtight strip 7 fits against the rear edge of the door leaf 2. The airtight strip 7 can absorb shock and... Sound insulation; the second groove of the door panel body 21 and the third groove of the outer cover plate 22 form a rectangular frame structure. The fireproof and smokeproof strip 8 is bent to form a rectangular frame. The fireproof and smokeproof strip 8 is attached to the inner side of the door frame 1. The fireproof and smokeproof strip 8 can isolate flames and smoke in the event of a fire. The door panel body 21 is formed by stamping a rectangular steel plate. The outer cover plate 22 covers the front, back, left and right sides of the door panel body 21. The outer cover plate 22 is formed by two steel plates being snapped together.
