Detailed Description
The fire-proof and smoke-proof door provided by the invention is further described in detail with reference to the attached drawings and the detailed description.
Referring to fig. 1 to 4, fig. 1 is a schematic top sectional view of a fire and smoke protection door according to an embodiment, fig. 2 is a schematic front view of the fire and smoke protection door according to an embodiment, fig. 3 is a schematic side sectional view of the fire and smoke protection door according to an embodiment, and fig. 4 is a schematic structural view of an automatic sinking type sealing strip according to an embodiment.
In this particular embodiment, there is provided a fire and smoke protection door comprising: a door frame 4; a door panel 5 mounted to the door frame 4; and the sealing strip is arranged at the bottom of the door panel 5 and used for isolating smoke.
In a specific embodiment, the fire-proof and smoke-proof door further comprises a door closer 1, two ends of which are respectively connected to the door frame 4 and the door panel 5, so that the door panel 5 is in a normally closed state.
In one embodiment, the sealing strip is an auto-plunge sealing strip 12.
In one embodiment, the self-ballasted sealing strip 12 includes a fire-resistant component that automatically extends into contact with and presses against the ground when the fire-resistant smoke damper is closed, closing the gap between the door bottom and the ground. In this embodiment, self-settling sealing strip 12 will automatically retract away from the ground when the fire and smoke protection door is opened.
In one embodiment, the extension and retraction of the fire protection components is controlled by pressing a knob against the doorframe 4. In a specific embodiment, the fireproof component is a sealing strip made of rubber, the length of the sealing strip is consistent with that of the door panel 5, when the door panel 5 of the fireproof and smoke-proof door is opened, the fireproof component can be lifted to be separated from the ground due to the fact that the door frame 4 extrudes the adjusting button to be separated from the extruded state; when the door plate 5 of the fireproof and smoke-proof door is closed, the door frame 4 extrudes the adjusting button to separate from the door frame and extrude the adjusting button, so that the fireproof component extends downwards.
Therefore, when a fire disaster occurs, the door panel 5 is closed, so that the fireproof component of the automatic sedimentation type sealing strip 12 automatically extends out of the bottom surface of the door panel 5, contacts with the ground, is in interference fit with the ground, and extrudes the ground, and the circulation of smoke from the bottom surface of the door panel 5 is blocked. Also, the self-settling sealing tape 12 also has a function of sound insulation when the door panel 5 is closed.
The self-settling seal strip 12 also helps to reduce the resistance to movement of the door panel 5 by lifting the fire protection components out of contact with the ground when the door panel 5 is opened.
In one embodiment, the door panel 5 includes: a cold-rolled steel sheet outer shell 8; and the fireproof filling core 9 is filled in the cold-rolled steel plate shell 8. In a specific embodiment, the door panel is further provided with a lock 3.
In a specific embodiment, a vertical center line of the fireproof filling core 9 is coincident with a vertical center line of the cold-rolled steel plate, and two side edges of the cold-rolled steel plate shell are provided with gaps; the door panel 5 further includes: and the flame-retardant plywood 10 is arranged on two side edges of the shell of the cold-rolled steel plate and is adjacent to the fireproof filling core 9.
In one embodiment, the door frame 4 is a galvanized cold rolled steel sheet 6 door frame 4.
In a specific embodiment, two ends of the bent portion of the door frame 4 are integrally arranged.
In one embodiment, a door stop is disposed on a surface of the door frame 4 facing the door panel 5, the door stop is disposed to protrude from a surface of the door frame 4, and a coating type sealing fireproof member 7 is disposed between the door stop and the door panel 5.
In a specific embodiment, the door stoppers are strip-shaped, the number of the door stoppers is three, the door stoppers are respectively arranged on the left side and the right side of the door frame 4, and the positions of the door stoppers on the left side and the right side are opposite.
In one embodiment, the door panel 5 is mounted to the door frame 4 by hinges 2 provided at the edges, and a hard shell fire seal 11 is provided between the door panel 5 and the door frame 4 on the mounting side of the hinges 2.
The fire prevention smoke protection door has the sealing strip that sets up in door plant 5 bottoms, can completely cut off the flue gas circulation of 5 sides of door plant, when the conflagration takes place, can cut off the dense cigarette of door both sides, for fleeing for more time of getting for one's life and death because of the personnel that the flue gas circulation caused when reducing the conflagration of taking place.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
