Embodiment

[0022] Embodiment: a kind of fire door, as figure 1 , figure 2 and image 3 Shown, it comprises door frame 7, is respectively arranged on the door panel 3,9 of door frame two sides. The door panels are bonded to the door frame by adhesive layers 4 and 8 respectively, and are nailed to the door frame by connectors 12 . Such as figure 1 Shown, the fire-facing side is one side, and the other side is the back-fire side, and the back-fire side door panel 3 adopts flame-retardant wood. For fire doors with both doors facing the fire, those skilled in the art can respond by themselves according to the description of this patent application. In order to save space, the structural diagram is omitted.

[0023] Also be provided with door frame 6 on the door frame 7, door frame 7 and door frame 6 all adopt flame-retardant wood, also be provided with heat insulation layer 5 between the door panels on both sides and be positioned at the cavity that door frame surrounds. The heat insula...

Abstract

The invention relates to a fireproof door used on a building. The fireproof door comprises a door frame and door plates which are respectively arranged at two sides of the door frame. The fireproof door is characterized in that the door plates are respectively glued with the door frame through bonding layers and nailed with the door frame through connecting members, and at least one side of the door plates is a counter-fire side and is a fireproof plate. The invention has the outstanding substantive characteristics that 1, at least one door plate is the fireproof plate, so that a flame retardant purpose is achieved; 2, the door frame, door mullions and an unexposed side are made of flame retardant materials and cannot spontaneously ignite at a relatively higher temperature, and the fireproof effect of the fireproof door is further improved; 3, a heat insulating layer is filled in a cavity formed by the two door plates, the door frame and the door mullions, which is favorable to reducing the high temperature of the counter-fire side, transferring the heat of the counter-fire side to the unexposed side, preventing the temperature from gradually raising and promoting flame retardant wood to lie in an environment below the spontaneous ignition temperature as much as possible; and 4, a metal layer is also arranged on the outer side of the counter-fire side, and deformation phenomena which are caused as different parts of the door plates lose different contents of water are avoided.

Description

technical field [0001] The invention relates to a fireproof door used in a building. When the fireproof door is closed, the fire can be prevented from spreading, which is beneficial to improving the safety of life and property. Background technique [0002] At present, there are no fire protection requirements and functions for household entrance doors and room doors. For the doors used in stairwells in public places such as hotels, shopping malls, office buildings, high-rise buildings, etc., it is necessary to achieve fire protection according to the provisions of the national fire protection code. But the room door, entrance door used in above-mentioned these public places do not have fire prevention function equally. [0003] Therefore, doors without fire protection function, in the event of a fire, even if the room door or the entrance door at the fire location is closed, these doors will be burned within a few minutes, which cannot prevent the fire from spreading, caus...
