Abstract

A fire-proof door curtain relates to the technical field of fire safety, and adopts the structure that a fire-proof door curtain cabin is made along a door frame, in which the fire-proof door curtain is stored in a folding manner. When the fire-proof door curtain is under a folded state, no influences can be caused to people's normal accesses. When a fire incident occurs, a switch outside the decorating plate of the fire-proof door curtain cabin is knocked, or an electrical-control relay is opened through a fire alarm central control room so as to open a lower cabin door of the fire-proof door curtain cabin, and the fire-proof door curtain is enabled to fall vertically, thereby taking effects of preventing fire behavior or stopping the spreading of the fire through resisting the air flow, and saving precious time for people.

Description

The fire prevention door curtain

Technical field

The utility model relates to the technical field of security against fire, specifically a kind of fire prevention door curtain.

Background technology

Along with our national economic development, high buildings and large mansions are built more and more, and people are movable in more and more intensive space, and electrical equipment and the inflammable articles used in work, life are also increasing, requirement for fire-fighting is also constantly improving, and the utility model is exactly a kind of fire protection of new ideas.

Summary of the invention

The purpose of this utility model is to provide a kind of new fire prevention door curtain, and it can provide the fireproof barrier one to people when in a single day the condition of a fire takes place, and also can flow by the blocking-up air in condition of a fire zone takes place, and prevents fire spreading.

Present Building Fire Protection generally is with water injector being installed and the corridor fireproof door being installed.It is very high to the requirement of building that fire-fighting spray device is installed, and is not suitable for all buildings.Be installed on the fireproof door of corridor, can be owing to daily use damages.Fireproof door has also been installed by the family that has now, but generally only installs on the gate of room and extraneous contact, and on oneself room inside door, generally can be by any fire prevention measure.Because fireproof door is relatively heavy, and is plain, daily use also very inconvenient.And the fire prevention door curtain of the utility model design has no requirement to the building that will install, no matter be the newly-built building or the transformation of old building, can install smoothly and use.The utility model be mounted in various door doorframe above, do not influence daily life, do not influence the finishing effect in house, need not operational maintenance and maintenance.But in case the condition of a fire takes place, the fire prevention door curtain can come into operation at once, even in the family that nobody looks after, or the people indoor can't open door in, it also can start automatically, opens the fire prevention door curtain, stops the intensity of a fire, for people try to gain time precious to one.

To achieve these goals, technical scheme of the present utility model is: do a fire prevention door curtain cabin in the upper edge of doorframe, the door curtain stored collapsed of will preventing fires is in fire prevention door curtain cabin.The fire prevention door curtain does not influence people's normal turnover when collapsed state.When the condition of a fire takes place the time, can knock the outer switch of fire prevention door curtain cabin decorative panel, perhaps open the following hatch door that automatically controlled relay is opened fire prevention door curtain cabin by the fire alarm central control room, the fire prevention door curtain is vertically fallen, play and stop the intensity of a fire or contain spreading of the intensity of a fire, for people try to gain time precious to one by flowing of blocks air.

In case the generation fire alarm because the strong wind that the effect of cold-hot air convection forms, always rushes at indoorly by door, and pass window and flow to the external world.The fire prevention door curtain of the utility model design is to make with fire proofing material, be installed in the outside of door, and the fire prevention door curtain in the evenly spaced lateral metal bar that penetrates, the fire prevention door curtain is wideer than the wooden frame of door, but it is slightly narrower than door opening, bonding jumper just can keep off outside the wooden frame of door like this, can prevent because strong wind sweeps the fire prevention door curtain.The below of fire prevention door curtain be the metal weights bar, is to guarantee that the fire prevention door curtain can fall rapidly during for hatch door under opening fire prevention door curtain cabin, and the while also can be played the effect that the door curtain that prevents to prevent fires is swept by strong wind.

The utility model is compared with existing product, because the door curtain that has adopted fire-proof fabric to do, put on bonding jumper again, be placed at ordinary times in the fire prevention door curtain cabin, do not influence people's daily life, need not maintaining, in case breaking out of fire, can play the retaining fire immediately, block big wind action, can effectively ensure the safety of people's life and property.
