BACKGROUND OF THE INVENTION
In the present invention, in order to prevent the spread of fire and the spread of smoke generated inside buildings such as buildings, spaces such as passages and openings inside buildings are partitioned by shielding members such as slat-shaped fire curtains and movable panels. relates to compartment forming apparatus for forming a compartment in relation to the block formation device in the case of having a pit other than evacuation routes in the elevator or the like, especially in the compartment.
[0002]
[Prior art]
Generally, high-rise buildings, etc. have pits such as elevators and escalators, so slat-shaped fire curtains and movable panels that close automatically when a fire occurs to prevent the spread of fire and the spread of smoke in the event of a fire. A partition forming device that operates to form a three-dimensionally enclosed space, i.e., a fire-proof and smoke-proof zone, is provided using a shielding member such as a pillar, a wall, and a floor.
[0003]
FIG. 1 is a diagram showing a schematic configuration of a conventional partition forming apparatus . In this section forming apparatus , the lobby 12 located between the bank type elevators provided so that the elevator groups 1 and 2 serving as potholes face each other is defined as one section. Around the lobby 12 of the bank type elevator, office sections 20 to 24 serving as living rooms are provided via hallways 30 to 35. In addition, in the figure, illustration is abbreviate | omitted about the staircase division provided with the pothole used as an evacuation route. Shielding devices used in this section forming device are fire curtain devices 10 and 11 and fire doors 13 and 14 having escape doors. The fire curtain devices 10 and 11 basically include a bracket attached to a beam or the like at the top of the building, a winding shaft rotatably attached to the bracket, and a slat curtain wound around the winding shaft. The The fire doors 13 and 14 are normally closed type or normally open type, and a part of them includes an evacuation door (evacuation door).
[0004]
[Problems to be solved by the invention]
Conventionally, when a fire occurs, the fire curtain devices 10 and 11 automatically lower the slat curtain in response to a signal from the smoke sensor (or heat sensor) and close the fire doors 13 and 14. Thus, the opening space between the lobby 12 and the corridors 30 to 33 is closed to form a pothole section. When a person is left in the lobby 12 which is a pit section, it is possible to evacuate from either of the fire doors 13 and 14 to the hallways 30 to 33 as indicated by dotted arrows 15 and 16. ing. The conventional evacuation doors of the fire doors 13 and 14 can evacuate from the lobby 12 side to the hallways 30 to 33, and conversely, can enter the lobby 12 from the hallways 30 to 33 side. This means that the user may enter the lobby 12 from the corridor 31 side through the evacuation door of the fire door 13 and evacuate to the corridor 32 through the evacuation door of the fire door 14 on the opposite side, that is, the lobby 12 that is a pit section. Is used as an evacuation route. From such a corridor, which is a safer section, it is not preferable from the viewpoint of evacuation to temporarily pass through a pothole section that is less safe than that.
[0005]
The objective of this invention is providing the division formation apparatus which can form the division which can avoid that a pothole division is utilized as an evacuation route.
[0006]
[Means for Solving the Problems]
A first feature of the section forming device according to the present invention is a section forming means for forming a plurality of sections in the building by extending a shielding member into the building to partition the space in the building,
An evacuation means having an automatic closing means and a latch means provided in a shielding member that forms a pit passage section that does not become an evacuation passage, and in order to enter the other section from the pit hole section, the latch means is operated by a normal operation. The evacuation means is opened by releasing and the latch release means arranged around the evacuation means of the other compartment is operated by operating the latch release means in order to enter the pit hole compartment from the other compartment The evacuation means can be opened only after the latch means is released. Even when the latch means is released by the operation of the latch release means, the evacuation means is And an evacuation means that is automatically closed and configured to return the latch means after closing.
The shielding member is provided in the building, and is extended from the inside of the building when a fire occurs. In the case where the shielding member is a fire curtain device, the fire curtain is provided at the upper part of the building and descends from an opening such as a lintel. In addition to this, a shielding member (such as a fire door) for fire prevention is drawn out by a horizontal pulling method or by a lifting method. The partition forming apparatus partitions the space inside the building by drawing out such a shielding member into the building, thereby forming a predetermined partition. Usually, shielding members such as fire curtain devices and fire doors are provided with evacuation doors or the like as evacuation means. Normally, it is possible to enter the other compartment from the pit zone via this evacuation means, or vice versa. However, in the present invention, entering the other compartment from the pit compartment via the evacuation means can be easily performed by opening the normal door, but conversely, entering the pit compartment from the other compartment is not possible. I can't do it. Note that it is not possible to enter the pit compartment from other sections at all, but it is possible by performing a special operation. For example, a normal door knob is provided on the side of the pit door of the evacuation door, and the door can be easily opened by operating it. The door knob is provided on the other side of the evacuation door. In addition, a pulling handle with a latch is provided, and the pulling handle can be operated only by operating a latch release device provided in another part of the latch so that the escape door can be opened. By doing in this way, it is prevented that the pothole section is erroneously used as an evacuation route. Moreover, when it is necessary to enter the pit hole section from another section, it can be entered by performing a special operation. The section forming apparatus according to the present invention is intended not only for high-rise buildings but also for buildings such as low-rise buildings and underground malls. Here, the normal operation is not a special operation for a member that is relatively easily noticed when an evacuee intends to pass through a shielding member or unconsciously tries to pass through. This is an operation that can be performed relatively easily. Accordingly, such an operation is preferably as easy as possible in consideration of the material and structure of the pit compartment and the shielding member, the psychological state of the evacuees, and the like. Also, the special operation refers to an operation that is difficult to pass when an evacuee tries to pass through the shielding member consciously or unconsciously, contrary to a normal operation. When attention is paid to at least one shielding member or a pothole section, it is an operation that is more difficult to pass than a normal operation, and in general, the operation is complicated and complicated. It is preferable that it is not easily noticeable. Needless to say, the present invention is not limited to these operations. In this way, the purpose of being able to pass through a special operation is to allow a rescuer to pass through, and it is preferable for such a person that the special operation is easy. . As another example of such a special operation, a password code input, fingerprint (voice print, retina pattern, etc.) collation, etc. may be performed. Note that the evacuation means may perform notifications and guidance prompting escape, announcements prohibiting entry, guidance to rescue workers, and the like by means of indications and sounds using marks and words.
[0007]
According to a second feature of the section forming apparatus according to the present invention, in the first feature, the pothole section has a pothole facility such as an elevator or an escalator. This indicates that a section provided with a pothole facility that cannot be used as an evacuation route such as an elevator or an escalator is a target of the pothole section of the present invention.
[0008]
According to a third feature of the section forming device according to the present invention, in the first or second feature, the evacuation means is constituted by an evacuation door provided in a part of the shielding member, and opens and closes the evacuation door. Opening / closing means for performing different configurations on the hole compartment side and the other compartment side. This is because the configuration of the evacuation door is different between the pit compartment side and the other compartment side, so when entering the other compartment from the pit compartment, it is possible to perform normal operations, and conversely from the other compartment to the pit compartment. In order to enter inside, it must be specially operated. As a specific example of a different configuration, as described above, the shape of the doorknob itself is changed between the side hole compartment side and the other compartment side, or even if the same door knob is used, the other compartment side is not opened unless a special operation is performed. Such a mechanism, for example, a latch release mechanism can be provided.
[0009]
According to a fourth feature of the section forming device according to the present invention, in the second feature, a bank-type elevator is included in the pothole section. In this case, a section provided with a bank type elevator as a pothole facility is a target of the pothole section of the present invention. Accordingly, the lobby portion of the bank type elevator is not used as an evacuation route in an emergency.
[0010]
According to a fifth feature of the section forming device according to the present invention, in the first, second, third, or fourth feature, a passage faces the other section on both sides of the hole section. . When the pothole section is located between the passages in the building, the pothole section may function as if it is a communication path between the passages. However, in the event of an emergency, it is not preferable to use this pit section as an evacuation passage from the viewpoint of safety. By applying the present invention, such a pit section is not used as an evacuation passage. I made it. Here, the passage means a communication path (for example, with a station premises) between a corridor, a merchandise store, etc. and other buildings, an underground shopping street, or the like.
