Description

Firewall device with water film {A fire wall having an aqua membrane}

The present invention relates to a firewall device that is installed for the purpose of preventing the spread of flame, in particular, by forming a water film by spraying water on the surface of the firewall during a fire, to suppress the rapid temperature rise of the firewall by the heat of vaporization generated from the formed water film In addition, the present invention relates to a firewall device in which a water film is formed to secure a field of view and to secure a skylight.

Conventionally used firewall devices are generally focused on installing and using a simple and convenient fire shutter.

The fire shutter is a firewall device having a shutter structure as is known.

In other words, because the current fire law mandates the installation of a firewall, it is a lot of fire shutters that are simple and easy to install.

However, the fire shutter does not prevent the leakage of toxic gas during the actual fire, and also burns or melts because it cannot endure the flame of high temperature, thus preventing the spread of the flame.

Therefore, it does not function as a firewall and only has a formal installation.

In addition, when using a fire shutter in normal or fire at the same time has a problem that it is difficult to secure visibility.

The present invention is designed to solve the problems of the conventional firewall device as described above, by forming a water film by spraying water on the surface of the firewall during a fire, thereby suppressing a sudden temperature rise of the firewall by the heat of vaporization generated from the formed water film In addition, the purpose of the present invention is to provide a firewall device in which a water film is formed so as to secure a field of vision and to secure a skylight.

This object can be achieved by the configuration of the subject innovation, will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of the subject innovation, Figure 2 is a plan view of the subject innovation, Figure 3 is a side cross-sectional view of the main part of the subject innovation.

As shown in the figure, the subject innovation is a firewall (10) partitioned inside the building and installed as a partition wall;

A supply pipe 20 installed on both outer surfaces of the upper portion of the firewall 10 and supplied with a fire extinguishing liquid;

It is formed of a plurality on the outer surface of the supply pipe 20, it is composed of an injection device 30 for injecting the extinguishing liquid toward the firewall.

Referring to the firewall 10 in detail, the firewall 10 uses a transparent material, it is preferable to use a tempered glass among the transparent material. It may be possible to use synthetic resins in addition to glass.

Herein, the glass uses tempered glass, and the tempered glass has a greater resistance to thermal stress than that of ordinary glass. This is because the glass is heat-treated to withstand high temperatures.

The maximum temperature that the firewall 10 can withstand when exposed to a general fire is 300 ° C. But temporarily, it can withstand higher temperatures.

In addition, when the water film is uniformly formed on the surface of the firewall 10, the fireproof performance may be greater than that of the firewall 10 itself.

Therefore, when the surface of the firewall 10 on which the water film is formed is exposed to a fire, it generally does not affect the rupture of the firewall 10. In general, unlike bricks and lightweight partition panels constituting the walls of the building in general, the firewall 10 using a transparent material has the advantage of not only to secure the view but also to secure the skylight.

In addition, the supply pipe 20 is installed on both outer surfaces of the upper portion of the firewall 10 in close proximity to the firewall.

In this case, a relatively large building, that is, most of the spaces equipped with water-based fire extinguishing facilities such as sprinklers in accordance with current fire regulations can supply water relatively easily. The water film may be formed by spraying water on 10.

Of course, even if the sprinkler is not a building to be installed, connecting pipes to the water supply line, etc., there will be no problem in securing the quantity.

In addition, the outer surface of the supply pipe 20 is formed of a plurality, the injection device 30 for injecting the extinguishing liquid toward the firewall is installed.

In more detail, when the injector 30 is continuously arranged on the outer surface of the supply pipe 20, the water film at the boundary portion where the water injected by the injector 30 and the water injected by the adjacent injector 30 meet each other. This can be overlapped to some extent to form a water film that is not shorted.

However, when the width of two water films overlaps, the water films do not overlap, but rather, the water flows down while creating a water column at the boundary.

Therefore, the distance between the injector 30 and the adjacent injector 30, which can form a uniform and short-circuited water film while minimizing overlapping width, is 420 mm is most suitable, and may be up to 450 mm.

On the other hand, the injection hole of the injection device 30 is spaced at least 5 cm away from the surface of the firewall (10).

In this case, the water film can be formed, and the heat of the heated supply pipe 20 does not directly affect the glass surface.

In addition, the distance between the water film and the glass surface sprayed by the injector 30 should be in the shape of a fan in order to naturally fall vertically along the surface of the firewall 10, the water film in the injector 30 The amount of rebound depends on the angle of incidence on the surface of the firewall 10, the separation distance between the surface of the firewall 10, and the injection device 30, and the water pressure.

Here, the rebound amount refers to the amount of water that is ejected from the injection port of the injector against the firewall.

Therefore, 0.38㎏ / ㎠ proved to be the most suitable water pressure by the experiment, the spray angle with the firewall 10 surface is 25 ℃, when the separation distance from the firewall surface 10 is 90mm to the smallest rebound amount It was investigated.

In addition, a frame 100 supporting the firewall is installed at the edge of the firewall 10, and the supply pipe fixing unit 300 may be installed on the upper portion of the frame so as to install the supply pipe 20.

Here, as described above, when the supply pipe is fixed to the supply pipe holder, the injection hole of the injection device 30 should be spaced at least 5 cm from the surface of the firewall 10 so that the water injected from the injection hole of the injection device is attached to the firewall. You can reduce the amount of rebound, the amount of water that comes out.

In addition, as shown in FIG. 3, the injector 30 is a spray nozzle 40 which ejects the extinguishing liquid into a free space at high speed.

The injection nozzle 40 is effectively used to eject the water supplied from the supply pipe 20 into the free space at high speed, and its structure and function are the same as those known in the art.

Figure 4 is a side view showing a state in which the sprinkler is attached according to another embodiment of the present invention, the overall structure of the present embodiment is the same as the case of Figures 1 and 2, but the injection device 30 detects the fire extinguishing fluid It is to the sprinkler 50 to spray.

The sprinkler 50, which is generally used on the outer surface of the supply pipe 20, is installed to spray the supplied water.

Here, the sprinkler 50 uses the same structure and function as those known.

Of course, in addition to the injection nozzle and the sprinkler, any device capable of injecting water can be used.

As described above, the present invention by forming a water film by spraying water on the surface of the firewall during the fire, by suppressing the rapid temperature rise of the firewall by the vaporization heat generated in the formed water film can withstand the high heat generated by the flame.

Therefore, the high heat generated by the flame prevents the firewall from burning or melting, thereby providing an effect of preventing the spread of the flame.

In addition, it is possible to secure the field of vision in normal times, and at the same time brings the effect of securing the skylight.
