Abstract
The invention belongs to the field of civil air defense engineering, and particularly relates to a protective airtight door with a fireproof function, which comprises a front door plate, a rear door plate, a sealing rubber strip and a silica gel sponge strip, wherein the front door plate and the rear door plate are connected by a plurality of supporting columns, fireproof cotton is filled in a cavity between the front door plate and the rear door plate, the sealing rubber strip is bonded on the rear door plate and used for sealing between the protective airtight door and a door frame, the silica gel sponge strip is arranged on the periphery of the sealing rubber strip and is 2cm-4cm away from the sealing rubber strip, and after the protective airtight door is locked, the silica gel sponge strip can be tightly attached to the door frame.
Description
Technical Field
The invention belongs to the field of civil air defense engineering, and particularly relates to a protective airtight door with a fireproof function.
Background
The civil air defense engineering is a short term civil air defense engineering, and refers to an underground protective building which is independently built for guaranteeing personnel and material shelter, civil air defense command and medical aid in wartime, and a basement (namely an air defense basement) protective airtight door which is built by combining the ground building and can be used for air defense in wartime, which is an important protective device in the civil air defense engineering, and the civil air defense engineering also has a fire fighting part. In the civil air defense engineering design and construction process at the present stage, the protective airtight door and the fireproof door are often arranged at one position and mutually blocked, and the installation, the opening and the closing are inconvenient.
Disclosure of Invention
The invention aims to provide a protective airtight door with a fireproof function, which is reliable in connection and high in butt joint speed.
The invention relates to a protective airtight door with a fireproof function, which comprises a front door plate, a rear door plate, a sealing rubber strip and a silica gel sponge strip, wherein the front door plate and the rear door plate are connected through a plurality of supporting columns, fireproof cotton is filled in a cavity between the front door plate and the rear door plate, the sealing rubber strip is bonded on the rear door plate and used for sealing between the protective airtight door and a door frame, the silica gel sponge strip is arranged on the periphery of the sealing rubber strip and is 2cm-4cm away from the sealing rubber strip on the rear door plate, and after the protective airtight door is locked, the silica gel sponge strip can be tightly attached to the door frame.
Further, the front door panel is thinner than the rear door panel.
Furthermore, the silica gel sponge strip is clamped in a T-shaped groove formed in the rear door panel.
The invention has the advantages that the protection function of the protective airtight door is realized by depending on the front door plate, the rear door plate and the plurality of supporting columns connected between the front door plate and the rear door plate, after the protective airtight door is locked, the sealing rubber strip is tightly pressed between the rear door plate and the door frame, the sealing function of the protective airtight door is realized, the fireproof function is realized by depending on the fireproof cotton filled between the front door plate and the rear door plate and the front door plate, the thermal deformation of the rear door plate is reduced, the sealing between the door and the door frame is kept, the silica gel sponge strip arranged at the periphery of the sealing rubber strip can be tightly attached to the door frame, the hot air flow is prevented from directly contacting with the sealing rubber strip, the damage and the deformation of the sealing rubber strip are prevented, and the sealing state of the protective airtight door is kept.
The invention relates to a protective airtight door with a fireproof function, which comprises a front door plate, a rear door plate, a sealing rubber strip and a silica gel sponge strip, wherein the front door plate and the rear door plate are connected through a plurality of supporting columns, fireproof cotton is filled in a cavity between the front door plate and the rear door plate, the sealing rubber strip is bonded on the rear door plate and used for sealing between the protective airtight door and a door frame, the silica gel sponge strip is arranged on the periphery of the sealing rubber strip and is 2cm-4cm away from the sealing rubber strip on the rear door plate, and after the protective airtight door is locked, the silica gel sponge strip can be tightly attached to the door frame.
Drawings
Fig. 1 is a structural view of an embodiment of a protective airtight door having a fire prevention function according to the present invention.
Fig. 2 is a sectional view taken along line M-M in fig. 1.
Fig. 3 is an enlarged view of the region N in fig. 2.
In the figure: 1. The fireproof door comprises a rear door plate, 2 a sealing rubber strip, 3 a silica gel sponge strip, 4 a front door plate, 5 a support column, 6 fireproof cotton.
Detailed Description
Fig. 1 to 3 show that the protective airtight door with the fireproof function comprises a front door plate 4, a rear door plate 1, a sealing rubber strip 2 and a silica gel sponge strip 3, wherein the front door plate 4 is thinner than the rear door plate 1 and is not easy to deform to protect the rear door plate, the front door plate 4 is connected with the rear door plate 1 through a plurality of supporting columns 5, fireproof cotton 6 is filled in a cavity between the front door plate 4 and the rear door plate 1, the sealing rubber strip 2 is bonded on the rear door plate 1 and is used for sealing between the protective airtight door and a door frame, the silica gel sponge strip 3 is arranged on the rear door plate at the periphery of the sealing rubber strip 2 and at a position about 2cm away from a sealant, and after the protective airtight door is locked, the silica gel sponge strip 3 can be tightly attached to the door frame to prevent hot air from contacting with the sealing rubber strip 2 and prevent the sealing rubber strip 2 from being damaged and deformed.
Claims (3)
