Technical Field

The utility model relates to a prevent fire door field, in particular to a steel prevents fire door that insulates against heat for taking refuge room.

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 advantages that the fireproof door has the effect of an ordinary door, and has the effects of preventing the fire from spreading and diffusing smoke, the fire can be prevented from spreading within a certain time, people are ensured to evacuate, after the fire occurs, the fire can be effectively blocked through the fireproof door, the escape time of trapped people is prolonged, most of the existing fireproof doors are doors made of wood, when the fire is more vigorous, the fireproof doors are easily damaged, the escape time of people is influenced, the escape time of the trapped people is not facilitated, the existing fireproof doors are relatively difficult to open and close in emergency, the safety of the people is influenced in emergency, and therefore, the ordinary fireproof doors have some problems in the using process, and therefore, the fireproof door is provided for the heat insulation steel between refuges.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a steel heat-insulation fireproof door for refuge room can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a steel is thermal-insulated prevents fire door for taking refuge, includes fire door shell and slide rail, one side fixed mounting who prevents the fire door shell has first fire-retardant sealing strip, and the fire door shell's surface one side installs the fire-retardant sealing strip of second about preventing fire door shell symmetry, the fixed surface of fire door shell installs the handle, and prevents the bottom fixed mounting of fire door shell and have the universal wheel, the intussuseption of fire door shell is filled with the asbestos insulating layer, the top fixed surface of slide rail installs sealed piece, and the surface of slide rail is located the one end fixed mounting of sealed piece and has sealed draw-in groove.

Preferably, the fireproof door shell is made of steel, and a connecting gap between the fireproof door shells is sealed by a first flame-retardant sealing strip.

Preferably, the number of the fireproof door shells is two, and the fireproof door shells are connected through hinges.

Preferably, the handles are symmetrically arranged on the outer surface of the shell of the fire door, and the number of the handles is two.

Preferably, the universal wheel is total two sets ofly, and the quantity of every group universal wheel is two, the even bottom of installing at the fire door shell.

Compared with the prior art, the utility model discloses following beneficial effect has: this a steel is thermal-insulated prevents fire door for taking refuge room, in the in-process of using, owing to be provided with the slide rail, consequently only need place on the slide rail through hinge connection's the fire door shell of preventing in the use, because there is the handle at the surface mounting who prevents the fire door shell, when emergency use, stranded personnel can easily quick remove the fire door shell on with the universal wheel through the handle and open, it closes it through the back is quick, and close the back, through the sealed of sealed piece with sealed draw-in groove, harmful gas's process has been blockked, thereby simple quick will prevent fire door and open and close, whole a steel is thermal-insulated prevents fire door for taking refuge room's simple structure, high durability and convenient operation, can be quick open and close and sealed provide more time for fleing, better for traditional mode.
