Description

Sequentially foldable fire rated door}

The present invention relates to a sequential folding fire door, and more particularly to a sequential folding fire door in which sequential control means for binding the folding door is attached to the fixing release mechanism so that the folding door of the fire door can be rotated sequentially. will be.

In general, fire doors are mandatory to be installed in buildings of a certain size or more as not only a component of a fire compartment to prevent the spread of fire in case of a fire in a house, apartment, factory, office, etc. .

These fire doors are installed at the entrance, which is the safest means of evacuation in case of fire, to block smoke or flames from the fire, thereby providing a space for people to evacuate safely.

Fire doors are always required to be closed, or to be closed automatically by the generation of smoke or temperature rises due to fire.

In other words, the fire door is normally kept open so that people or goods can enter and exit, and automatically close in case of fire.

In order to solve this problem, a rotary fire door is disclosed in Korean Patent Publication No. 10-0750903.

The Republic of Korea Patent Publication No. 10-0750903 is installed in a wide entrance door fired by the left and right folding configuration is released when the heat release fuse blows the door release is the rise of the ambient temperature in the event of a fire is released by the drive of the auto hinge The door swings and closes.

However, since the rotation speed of the auto hinge is not controlled separately, the double overlapping doors do not spread out sequentially while the door release is released, and at the same time as the release of the door release, the double overlapping doors are unfolded before closing the door. This was doubled up to a maximum, requiring more space for installation.

In addition, both types of fire doors are formed, the work time and cost for installing the fire doors are raised.

In general, when the door is closed, one of the plurality of doors is provided to be opened and closed for people who have not been evacuated to the fire protection zone. Let the door lock.

However, since most people are inexperienced in using fire doors, they attempt to close the fire doors while the automatic lifting bolts are raised, causing the fire to spread without the doors being completely closed.

It is disposed to one side while automatically rotating to the rear by the), the first door 310 is maintained in a closed state.

At the same time, the sequential regulator 420 installed on the first door 310 is attached to the fixing release mechanism 200 installed at the corresponding point, and the binding of the first door 310 and the third door 330 is released. And as shown in Figure 4- (c), the second door 320 and the third door 330 is rotated to the rear by the second rotating member 302 is disposed to one side, the second door 320 ) Remains closed.

In addition, at the same time, the sequential regulator 420 installed on the second door 320 is attached to the fixing release mechanism 200 installed at the corresponding point, and the binding between the second door 320 and the third door 330 is released. . And Referring to Figure 4 (c), the third door 330 is rotated to the rear by the third rotating member 303 is disposed to one side, the third door 330 is maintained in a closed state.

5 to 7, another embodiment of a sequential folding fire door according to the present invention will be described.

An automatic elevating bolt 510 is installed on the upper side of the folding door 300 to allow the folding door 300 to be automatically lifted to close the fire door. The automatic lifting bolt 510 is preferably installed on at least one or more of the first door 310 and the second door 320, and those who have not been evacuated to the fire protection zone may move the third door 330. Be prepared to evacuate through Here, the automatic lifting bolt 510 has a structure in which the protrusion of the side is raised and lifted upward while most of the door is opened. At this time, the person who is not familiar with the use of the fire door attempts to close the fire door in the state in which the automatic lifting bolt 510 is elevated, the fire door is opened without closing the fire spreads.

In order to prevent such a problem is formed to open the set section on the front of the upper horizontal frame 110, the opening and closing preventing means 520 is installed in the open section. Here, the opening and closing failure prevention means 520 is disposed in a position corresponding to the automatic lifting bolt 510, the upper end is fixed and connected to the upper horizontal frame 110, the lower end is provided to rotate in the rearward direction. By the structure of the opening and closing prevention means 520 as described above, even when the automatic lifting bolt 510 is lifted and inserted into the opening and closing prevention means 520 side, the door can be closed, and those who are not familiar with the use of fire doors The closed first door 310 and the second door 320 may be prevented from opening.

More specifically, the opening and closing prevention means 520 may be composed of a fixture 521, the main preventive 522, the auxiliary preventive 523. Fixture 521 is made of a pair, is formed as a vertical plate is installed spaced apart inside the front of the upper horizontal frame (110). The fixture 521 is preferably the bottom surface is welded fixed to the inner surface of the upper horizontal frame (110). And the main preventer 522 is formed of a horizontal plate, disposed horizontally between the fixture 521, the upper end is connected and fixed by the fixture 521 and the rotation pin, the lower end is equipped to rotate in the rear direction . In addition, the auxiliary guard 523 is formed in the same shape as the main guard 522, the upper end is fixed to the lower end of the main guard 522 by a rotation pin, the lower end is equipped to rotate in the rear direction. . The auxiliary preventer 523 is formed to have a shorter length than the main preventer 522 to help the automatic lifting bolt 510 to be lifted and inserted into the opening / closing preventing means 520.

8 to 10, another embodiment of a sequential folding fire door according to the present invention will be described.

The sequential foldable fire door is provided so that the foldable door 300 rotates and closes while the first, second, and third rotating members 301, 302, 303 made of an auto hinge are driven by the operation of the door release. At this time, the folding door 300 is provided with a magnetic fastener 610 at the bottom, the stopper member 620 is embedded in the ground corresponding to the folding door 300 is tightly closed by the rotational force as the doorless door frame 100 To avoid leaving the position. The stopper member 620 is attached to the magnet fastener 610 while the folding door 300 is closed, the folding door 300 is fixed at the correct position of the door frame (100). Due to the magnet fixture 610 and the stopper member 620 it is possible to quickly block the fire protection area.

Therefore, the magnet fixture 610 is made of a magnetic material, it is preferable to be installed in at least one lower portion of the first door 310 and the second door 320. The magnetic fixture 610 is installed in the longitudinal direction on the lower surface of the door for fast fixing the fixed position of the folding door 300 so that the entire lower part of the folding door 300 does not leave the position of the door frame 100.

More specifically, the stopper member 620 may be formed of a fixing bracket 621, a bottom fixing tool 622, and a rotation pin 623. The fixing bracket 621 is made up of a pair of vertical plates, disposed in a position corresponding to the magnet fixture 610, and is fixedly spaced apart from the lower end of the first door 310 or the second door 320. And the bottom fixture 622 is installed between the horizontal plate is fixed between the bracket 621, one end is bent inward downward and attached to the magnet fixture 610. And the rotation pin 623 is provided so that the other end of the bottom fixture and the fixing bracket 621 is connected so that one end of the bottom fixture 622 is rotated upward. In particular, the stopper member 620 may be formed to have the same width as the length of the magnet fixing tool 610 to widen the area to be attached, thereby improving coupling force with the stopper member 620.

By such a magnetic fixture 610 and the stopper member 620 it is possible to prevent the lower thermal deformation of the folding door 300. In addition, the magnet fixture 610 is formed of a magnetic gasket, the stopper member 620 is easily attached, the lower portion of the folding door 300 can be sealed so that flames or smoke does not flow.
