Description

  The present invention relates to a fire protection compartment formation auxiliary device.

  Buildings are obliged to have fire-prevention compartments with a prescribed fire resistance for the purpose of facilitating the prevention of expansion, evacuation, fire extinguishing, rescue activities, etc. in the event of a fire.

  Further, as a means for forming the fire prevention compartment, a fire prevention device that normally allows passage of people and prevents the penetration of the flame at the time of a fire to form the fire prevention compartment is used. As this fire prevention device, as shown in FIG. In many cases, a fire prevention shutter 2 that automatically descends in conjunction with the operation of the fire detector 1 to form a fire prevention compartment in the event of a fire is used.

  In addition, there has been a configuration in which a safety device is provided to detect an obstacle at the lower part of the fire shutter and automatically stop the fire shutter from being lowered because a personal accident has occurred between the fire shutter that automatically descends ( For example, see Patent Document 1).

  On the other hand, if such a safety device is provided, an obstacle such as a cardboard box will be detected in the event of a fire, and the fire shutter will stop descending. This causes the inconvenience that the partition cannot be formed.

  On the other hand, a fire-resistant shutter or other deformable fire-resistant member such as a cloth-like member is provided at the bottom of the fire shutter, or a falling water curtain is formed by spraying water from the water spray head toward the fire shutter. Even when the shutter is not completely lowered, a method of forming a fire prevention section with these cloth-like members and the falling water curtain has been proposed (for example, see Patent Document 2).
