Description

Fire-proof shutter which prevents random opening of emergency door by stripped structure of belt

The present invention relates to a fire prevention shutter for blocking smoke and flames in a fire, and to prevent the warping of the screen cloth and the strip while winding the emergency door made by the overlapping of the screen cloth. .

In general, fire shutters are used to partition fire and flameproof areas in a building so as to prevent the spread of fire and facilitate evacuation in the event of a fire in a building. In the past, shutter plates are made of steel, but recently heat resistance is strong. However, fire shutters are mainly used because they can be installed at a low cost by using a thin and light screen cloth.

The fire and smoke zones are simply to prevent the spread of fire and smoke. When the passage inside the building is blocked by the fire shutter, an emergency door is provided to the fire shutter itself to secure the evacuation path of the person inside. By installing, the evacuation route can be used even when the area is blocked.

Such an emergency door is preferably installed at the center of the fire shutter so that the evacuator can easily check with the naked eye.In order to install the emergency door, the emergency exit can be opened by double-mounting the screen cloth so that the parts overlap each other. It will be secured.

However, the problem of this is that only the lower part of the screen fabric is fixed by the lower frame, so that a gap occurs in the overlapped portions of the screen fabric, and smoke leaks through the gap, so that the fire and flame retardant effect is very low. There is a problem that can not function properly.

Therefore, in order to prevent this, the bulk cloth fastener is attached to the overlapping part of the screen cloth, but when the actual fire, the interior of the building is very high temperature, so the bulk fastener burns or melts, and thus the effectiveness is inferior.

In another method, a part of the screen fabric is cut out to form an emergency door, and a frame is coupled to the edge to close the emergency door. However, such a method has been proposed so that the screen cloth to be raised and lowered has a completely closed structure. It is difficult to do and the structure itself is very complicated, which makes it difficult to manufacture, and there is a risk of injury due to the steel frame when using emergency doors in an emergency situation, and also inevitably occur in the connection part where the frame is formed. As the smoke leaks through the fire prevention and the fire effect of the fire shutter is deteriorated.

Therefore, the present invention forms an emergency door in the center of the fire screen shutter made of a screen cloth, while the structure of the emergency door is prevented from being tightly closed and prevents the screen cloth from being deformed even when the fire door is lifted or lowered. To keep it.

To this end, the present invention is fixed to the guide frame on both sides of the screen fabric is to be moved up and down, the screen fabric is overlapped in the state divided in the center to form an emergency door in a structure that is folded by the hinge of the lower frame It forms a belt that is raised and lowered along the screen fabric at the edge of the door to prevent the emergency door from being opened by the belt, while maintaining the close contact with the screen fabric.

Further, by separately forming a reel shaft for winding the belt on the upper end of the shaft for winding the screen cloth to be wound at the same time by the shaft and the reel shaft and the screen cloth.

Therefore, the present invention is to maintain the blocking state of the fire shutter, while preventing the opening of the emergency door by the band to be rolled or unwinding each screen cloth and strip by the two shafts integrally moving, In addition, even though the screen cloth and the strip is overlapped, it is accurately wound without misalignment to prevent the screen cloth from curling and preventing damage or tearing.
