The present invention relates to an emergency exit of the fire door.

A fire shutter door is provided as a means of effectively preventing the spread of toxic gases and flames during an initial fire in the event of a fire in a multi-story high-rise building or other complex commercial buildings. That is, by detecting the fire generator flame, the brake that prevents the shutter slat from falling down of the shutter box is released, and the wound shutter immediately descends to block the emergency bulb, thereby preventing the propagation of the flame. In this case, the problem is that when a person who remains at the fire site cannot escape, a separate exit is required for their escape.

In order to solve this problem, we developed an emergency door that lifts and bends in the same direction with the shutter plate through hinges coupled to each shutter member at the lower side of the shutter plate in the Korean Utility Announcement 93-6476 Building Shutter. The hinges with built-in hinges ensure that the emergency door is always closed.

In the above emergency door for fire shutter, the emergency door can also be wound up when the shutter is wound. There was a problem, and it was pointed out that it does not close completely when opening and closing the emergency door. Furthermore, the emergency door must be installed on one side, and if the emergency exit installation part is concentrated in the center unlike the normal door, there is a fatal disadvantage in use that the emergency exit that is on one side cannot be used after the fire shutter is lowered.

In order to improve the shortcomings of the above emergency exit, the inventor of the patent application No. 24304 in 1994 improved the circuit of the automatic closing machine to prevent the damage of the AC solenoid and the shutter plate and to automatically return the connection between the emergency door and the shutter by using the compression spring. The gas shut-off port was installed at the connection part so that the fire door could function without emergency loss. Even in this case, the intended gas shutoff and flame prevention function could be secured, but the opening of the compression spring was inaccurate according to the strength and direction of movement. It was possible.

The present invention, in the emergency door of the shutter plate is formed by connecting a plurality of shutter members, by using a hinge with excellent sealing properties and door hinges excellent in literal function and by forming a predetermined movement preventing portion in the connection function of the emergency door Its purpose is to provide an emergency door for fire prevention shutters without loss of seizure and ensuring excellent sealing. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a shutter in the emergency door is attached to the lower side of one side of the fire prevention shutter plate configured to wind or release the shutter plate which is fastened to each other at the front end bent portion of the member end in accordance with the driving device, Each door of the member 10 can be opened and closed between the emergency door 40 and the shutter 50 by installing a hinge 12 having a coupler formed at the upper and lower sides and a door shank 20 having a dual structure spring spring. The above-mentioned shortcomings were solved by providing a new emergency door in which the flow prevention device 30 was installed in the middle of each slat and the hinge 12 and the door shank 20 were alternately arranged.

The hinge 12 used in the present invention has a left and right extended portion 16 extending vertically up and down the middle part where the left and right brackets connecting the brackets 14 and 15 on the left and right about the pivot axis 13 meet. (17) was formed, and the sealing parts were formed so as to overlap with each other to form the north drum (18) (19). In the case of the present design, the shape of the coupler 18, 19 is a stepped shape, but various irregularities can be used as needed, and as another method, it can be provided with a strong sealing property by being fitted with an elastic material. It is.

The door shank 20 of the present invention is coupled to the outer bracket 21 and the inner bracket 22 from the shaft hole 23 to the hinge shaft 24, both ends of the outer liter spring 25 is the outer bracket (21) At the top and bottom of the center, the center is bent with a c-shape so as to span the side end of the inner bracket 22, and both ends of the inner literal spring 26 are bent at the top and bottom of the inner bracket 22, and the center is bent with a c-shape. It was installed to span the side end of the bracket 21 so that the inner and outer brackets were always spread in one direction.

The outer bracket 21 and the inner bracket 22 form shaft protrusions 27 and 27a, respectively, so that the shaft protrusion 27a of the inner bracket 22 is partially inserted into the guide slit 28 so that the rear bracket 21 The jaw portion 29 has a stop function. The inner bracket 22 and the outer bracket 21 are each formed with sealing portions 22a and 21a, and the upper and lower coupling holes are formed at the respective ends thereof so as to be engaged with the upper and lower coupling holes 18 and 19 of the door hinge 12. 22b and 21b were formed.

The flow preventing device 30 of the present invention has a slat having the same cross-sectional structure as each connector 31. In the present invention, the slab has a disk shape and the same diameter as that of the connector 31, and then is inserted into the cutting part 32 and welded. It is installed by processing. Flow arresters may be installed for each end of each slat, but may be installed at intervals of two to three, if necessary, depending on the total length and weight of the slats and the type of emergency door installation.

Referring to the operational relationship of the present invention according to the above structural features as follows.

The shutter member 10 is cut according to the size of the emergency door to be installed, and then the hinge 12 and the door shank 20 of the present invention are placed at a predetermined distance d between the shutter member and the emergency door as the base frame. Install. When the hinge 12 is installed on the uppermost slat, the door shank 20 is installed in the following order. At this time, the upper engagement hole 22b of the door shank 20 is connected to the lower engaging hole 19 of the hinge 12. It is tightening while inserting (FIG. 3).

When the fastening is completed to the lowermost shutter member, as shown in FIG. 5, the cutting part 32 is formed on the left and right connecting parts 31 of the emergency door installation part, and then the flow prevention device of the thin plate having the same shape as the cross-sectional structure of the cutting part 32 is formed. (30) is inserted and welded. In this paper, as shown in FIG. 5, a separate finishing material 60 was continuously installed on the left and right sides of the slat from the top to the bottom of the emergency door. Finishing material 60 is inserted projection 61 and the insertion groove 62 is formed in the upper and lower sides and the fixing bracket 63 is formed on the side to integrate the side end surface of the slat by welding or screwing method and the upper and lower parts of the finishing material The thickness of the connection part is smaller than or slightly smaller than the thickness of the connection part, and the left and right ends of the connection part are sealed when installed.

When the assembly is completed, the door shank 20 of the present invention is operated by the inner and outer spring 26, 25, the emergency door is kept closed, and the distance d between the emergency door and the shutter member is When the emergency door is opened, the cutting tips 31a and 31b of the connector come into contact with each other, so that the opening is blocked. At the same time, the flame propagation prevention function of the emergency door can be used as it is.

In addition, since the door shank 20 installs two liter springs per piece, it pushes the inner and outer brackets 21 and 22 at four points, thereby achieving accuracy of opening and closing operation due to the equality of force. It is. In addition, when the finishing material 60 is fixed to the left and right end face of each slat, it prevents the left and right swing of the slat and ensures the fastness and stability of assembly. Since is not observed will be able to implement a more beautiful appearance in appearance.
