Abstract
The utility model relates to a prevent fire door, especially prevent fire door leaf. The door core plate is arranged between the front panel and the back panel; the four sides of the front panel and the back panel are respectively provided with a hem structure, a gap is arranged between the hem structure of the front panel and the hem structure of the back panel, and a sealing strip which expands when heated is arranged at the gap. The utility model arranges a gap between the front and back panels and installs the heat expandable sealing strip, so that the heat generated by fire can be cut off at the gap between the front and back panels, thereby preventing the heat from transferring and improving the safety; the front and back panels adopt the edge folding structure, an electric welding machine is not used in the production process, welding smoke and dust cannot be generated, the environment can be protected, the process is simple, and the cost is low.
Description
Technical Field
The utility model relates to a prevent fire door, especially prevent fire door leaf.
Background
A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. It is a fire-proof partition with certain fire resistance, which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like. The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people. The fireproof door is composed of a door frame and a door leaf, and the door leaf plays roles in heat insulation and smoke isolation. The door leaf comprises door core board and panel, and the whole cladding of door core board is in the panel, and the department of sealing of panel adopts the seam to connect, and when the conflagration breaing out, this kind of structure can make the heat transmit through the panel, can cause harm to the personnel in the fire prevention door.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a thermal-insulated effectual, safer prevent fire door leaf.
The utility model provides a technical scheme that its technical problem adopted is:
a fireproof door leaf comprises a door core plate, a front panel and a back panel, wherein the door core plate is arranged between the front panel and the back panel; the four sides of the front panel and the back panel are respectively provided with a hem structure, a gap is arranged between the hem structure of the front panel and the hem structure of the back panel, and a sealing strip which expands when heated is arranged at the gap.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
the gap is arranged between the front panel and the back panel, and the sealing strip which expands when heated is arranged, so that heat generated by fire can be isolated at the gap between the front panel and the back panel, the heat transfer is prevented, and the safety is improved; the front and back panels adopt the edge folding structure, an electric welding machine is not used in the production process, welding smoke and dust cannot be generated, the environment can be protected, the process is simple, and the cost is low.
Further, the utility model discloses an optimization scheme is:
the folding edge structures of the front panel and the back panel are in a step shape.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, a front panel 1; a door core panel 2; a back panel 3; a hem structure 4; and a seal strip 5.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, a fireproof door leaf comprises a front panel 1, a door core panel 2, a back panel 3, a folding structure 4 and a sealing strip 5. The material of front panel 1 and backplate 3 is the steel sheet, hem structure 4 has been processed respectively on four limits of front panel 1 and backplate 3, hem structure 4 is the stairstepping, front panel 1 and backplate 3 are corresponding, door core 2 cladding is in front panel 1 and backplate 3, front panel 1 and backplate 3's hem structure 4 compresses tightly four sides of door core 2, be equipped with the clearance between the hem structure of front panel 1 and backplate 3's the hem structure, the clearance department installs the sealing strip 5 of meeting the thermal expansion, sealing strip 5 encircles 2 a week of door core. When a fire breaks out, the sealing strips 5 are heated and expanded, and heat generated by the fire is cut off at the gaps, so that toxic hot gas is prevented from entering a room.
A connecting plate is arranged on one side of the door leaf, the door leaf is arranged on the door frame through a hinge between the connecting plate and the door frame, and a door lock is arranged on the other side of the door leaf.
The fireproof door leaf of the embodiment does not need to be welded in the production process, does not produce welding smoke dust, does not produce environmental pollution, is energy-saving and environment-friendly, and reduces the production cost.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
