Description of the Related Art A pressurized smoke prevention system is a smoke control system that replaces the smoke exhaust system that sucks out the smoke that has entered the evacuation route to the outside. It is a system that pressurizes the staircase zone side to actively prevent smoke from entering the evacuation route.
The number of buildings using this pressurized smoke prevention system is increasing in Japan.

Is set. In FIG. 1 (A), smoke exhaust fan mechanisms 1a, 2a, and 3a for sucking out smoke are provided in the living room zone 1, the corridor zone 2, and the annex room zone 3, respectively, and in the corridor zone 2 and the annex room zone 3, respectively. Pressurizing fan mechanisms 2b and 3b are provided for pumping and introducing outside air. 1B is an example in which the smoke exhaust fan mechanism 2a in the corridor zone 2 is eliminated, and FIG. 1C is an example in which the smoke exhaust fan mechanism 3a in the annex room zone 3 is also eliminated.

を防ぐ。When a fire occurs in the living room zone 1, the smoke exhaust fan mechanism 1a is activated and the pressure fan mechanisms 2b and 3b are activated (the smoke exhaust fan mechanisms 2a and 2b are activated depending on the situation). This pressurizes the corridor zone 2 and the ancillary room zone 3 against the fire chamber and prevents smoke from the fire chamber from entering the evacuation route leading to the staircase zone 4.

As shown in (C), in the conventional pressurized smoke prevention system,
The corridor zone 2 and the annex room zone 3 are provided with independent pressurizing fan mechanisms 2b and 3b, respectively, to pressurize both zones separately. Originally, in the pressurized smoke prevention system, the pressure in the annex room zone 3 should be higher than that in the corridor zone 2, but in the conventional system, the pressure level may be reversed depending on the situation. In other words, the pressure in the ancillary room zone 3 may change depending on the opening / closing status of many doors partitioning each zone and the malfunction of the fan mechanism.
A lower state may occur, and smoke that has entered the corridor zone 2 may spread to the annex room zone 3 at an accelerated rate.

It is to provide a pressurized smoke prevention system capable of performing the above.

The annex room zone 3 is set as a buffer zone between the corridor zone 2 and the evacuation staircase zone 4. A smoke exhaust fan mechanism 1a for sucking out smoke is provided in the living room zone 1. The pressurizing fan mechanism 3b for pumping and introducing the outside air is provided only in the annex room zone 3, and the corridor zone 2 is not provided with the pressurizing fan mechanism.

The pressure of the auxiliary room zone 3 acts on the inlet side of the relief damper 5, and the pressure of the corridor zone 2 acts on the outlet side. When the pressure difference between the inlet side and the outlet side exceeds a set value (for example, about 5 pascals), the relief damper 5 automatically opens due to the pressure difference, and the annex room zone 3 and the corridor zone 2 communicate with each other.

As a result, the outside air is pumped into the auxiliary room zone 3 to pressurize the auxiliary room zone 3, and when the pressure in the auxiliary room zone 3 becomes higher than the pressure in the corridor zone 2 by a predetermined value or more, the pressure-sensitive damper mechanism 5 automatically operates. Open, the annex zone 3 and the corridor zone 2 communicate,
The pressure in the annex zone 3 extends to the corridor zone 2. When the pressure in the corridor zone 2 becomes high for some reason, and the pressure difference between it and the annex room zone 3 becomes less than the predetermined value, the pressure-sensitive damper mechanism 5 automatically closes. In this way, the ancillary room zone 3 is reliably kept at a higher pressure than the corridor zone 2, and the original operation of the pressurized smoke prevention system is stably exhibited.

設備コストが安くなる。As described in detail above, the pressurized smoke prevention system of the present invention is provided with a pressurizing fan mechanism for pumping and introducing outside air with a fan in the annex room zone, and the pressure of the annex room zone is the corridor zone. If a pressure-sensitive damper mechanism is provided that automatically opens when the pressure is higher than the specified value by the pressure difference and connects both zones, the pressure fan mechanism is activated in the event of a fire. Is pressurized, and when the pressure becomes sufficiently high, the pressure-sensitive damper mechanism automatically opens and the corridor zone is also pressurized. However,
The pressure in the corridor zone is kept lower than in the annex zone. Therefore, it is possible to stably and reliably realize the smoke proof action as originally intended by the pressurized smoke proof system. Further, since the pressure fan mechanism is provided only in the attached room zone, the equipment cost is lower than that of the conventional equipment.

とを特徴とする加圧防煙システム。1. A pressurizing fan mechanism for pumping and introducing outside air into a supplementary room zone, which is a buffer zone between a living room and a corridor zone and a staircase room zone of an evacuation route, and between the supplementary room zone and the corridor zone. And a pressure-sensitive damper mechanism that is opened by the pressure difference when the pressure in the annex room zone is higher than the pressure in the corridor zone by a predetermined value or more to communicate the annex room zone and the corridor zone. A pressurized smoke prevention system characterized in that
