[0023]
Next, the operation of the partition formation system when a fire occurs will be described. The panels 21 to 23 are normally in an open state and are stored in a door pocket or the like (not shown). When a fire occurs, a smoke sensor (not shown), a heat sensor (not shown), etc. installed on the ceiling are activated. Then, a detection signal from the smoke detector is transmitted to the disaster prevention center. A stopper such as an electromagnetic release is released according to an instruction from the Disaster Prevention Center and a water system is activated. The power source starts to operate in order to move the panels 21 to 23 as the heat shield structure by releasing the electromagnetic release. The panels 21 to 23, which are heat shield structures, start an automatic closing operation by the operation of the power source. The closing operation of the panels 21 to 23 as the heat shield structure is completed. A completion signal is output when the closing operation of the heat shield structure is completed, or a predetermined time elapse signal is output from a timer that has timed a predetermined time after the closing operation of the heat shield structure starts. . By inputting a completion signal or a predetermined time elapsed signal, water supply to the pipe 13 is started. As a result, the panels 21 to 23 are fully closed, and the water from the pipe 13 forms a heat shield wall with a water film in the panels 21 to 23, so that high heat shield performance is exhibited. Become. In addition, when the smoke sensor and the heat sensor are used in combination, according to the instruction from the smoke sensor, the stopper such as the electromagnetic release is released and the water system is activated, and the heat sensor (Fig. (Not shown), a heat sensing unit signal is detected, and the heat sensing unit signal is transmitted to the disaster prevention center and others, and water may be supplied from the disaster prevention center to the pipe 13 in accordance with the heat sensing unit signal.
[0024]
Next, the flow of water supplied from the pipe 13 will be described. The pipe 13 is supplied with water from a water storage tank (or tap water). Water supplied from the pipe 13 flows into the upper strength bones 41 and 411 through a plurality of openings provided in the L-shaped steel 14 and the rail 12. A part of the water that has flowed into the upper strength bones 41 and 411 passes through the water injection ports 61 to 63 and 71 to 73 of the upper strength bone 41 or the water injection ports of the upper strength bone 411 and the longitudinal strength bones 43 to 45, 431, and 451. And flows into the hollow portions of the door stops 25 and 26 through the pipes 25B and 26A. On the other hand, the remainder of the water that has flowed into the upper strength bones 41, 411 is the cotton-like member 51, the sheet-like moisture retention member 91, or the moisture retention sheet 102 through the water inlets 64 to 67, 74 to 77 or the water inlet of the upper strength bone 411. It flows into the water and is absorbed by moisture. Further, the water that is not held by the cotton-like member 51, the sheet-like moisturizing member 91 or the moisturizing sheet 102 is discharged from the drainage port of the lower strength bone 42. Further, the evaporated water vapor is exhausted from the discharge port and the water injection port.
[0025]
As described above, according to this embodiment, since the member can be cooled with water regardless of the opening width dimension of the fire prevention compartment, the heat shielding effect is remarkably high. Further, the heat shielding effect can be maintained with a small amount of water. In addition, since it is sufficient that the water can flow in the pipe, it is not necessary to pressurize with a pump, tap water can be used directly, and it is not necessary to provide a water storage tank or the like in advance. The distance between the panel member to be cooled and the pipe through which water flows may be relatively small. The entire panel can be insulated uniformly. Moreover, a spray nozzle is not necessary. Moreover, since the aggregate part (stress) does not become a heat bridge, the cooling effect is great.
[0026]
In the above-described embodiment, the panel that moves from the inside of the building by the horizontal pulling method at the time of the fire has been described as an example, but other than this, a shielding member for fire prevention is drawn out from the upper side by the lowering method or lifted. Even if it is paid out by a method, it can be similarly applied. For example, the present invention can be similarly applied to a device that uses a fire shutter device that shields the shutter member that is a shielding member while being lowered. In this case, the shutter curtain may be doubled and a cotton-like member may be provided therebetween. Further, in addition to the fire-proof shutter device, a shutter-like shielding member can be similarly applied even if it is extended by a horizontal pulling method, extended by a lifting method, or extended by a horizontal method. In addition to fire prevention purposes, it can also be applied to purposes such as smoke prevention, crime prevention, sun protection, rain protection, etc., depending on the installation location and surrounding environment, conditions, and various circumstances. Examples of the opening / closing device include a shutter device, a door device, a blind device, a roll screen device, and a banner device. In addition, the material of the cotton-like member may be any material as long as it absorbs and retains water throughout the whole. However, in the case of a switchgear installed for the purpose of fire prevention, it has at least fire resistance. It goes without saying that what is being done is preferred.
[0027]
【The invention's effect】
As described above, according to the heat shield structure and the partition formation system of the present invention, there is an effect that it is comparatively lightweight when it is movable, and can fully exert a heat shield effect when a fire occurs.
