Description

[0001] The present invention relates to an automatic closing louver device for fire prevention,

The present invention relates to an automatic fire prevention system that automatically adjusts lighting to be installed in a window or a building structure such as a curtain wall type building without a balcony function, Closure louver device.

FIG. 1 is a conceptual view showing a state in which a flame is transferred to an upper layer when a fire occurs in a fire layer in a multi-story building, and FIG. 2 is a recent example in which a flame is moved to an upper layer through a window in a multi-story building.

Window (WD) is an indispensable building element for mining and ventilation. However, in the case of a multi-storied building, the flame (F) in the lower layer during the fire acts as a crucial passage through the outer wall to the upper layer.

This is because when the flame F rises to the outside of the building, the flame F rides on the outer wall of the building and diffuses through the window WD of the upper layer as shown in Fig. 1 (a).

The basic method for preventing the spread of the flame F is to install the balcony B or the waist W so that the flame does not reach the window of the upper layer as shown in Figs. 1 (b) and 1 (c) . In particular, since the balcony (B) can function as an evacuation space for escape in an emergency in addition to the above-mentioned function of preventing flame spread, it also shields direct sunlight and thus can be used in almost all buildings including existing houses .

In recent years, however, the balcony (B), which is open to the outside due to dust and noise due to pollution, is being used as a warehouse such as a warehouse where objects are stored by windows and is illegally expanded and used as an indoor space.

As a result of many such illegal expansions, from 2006 onwards, the extension of the balcony was legally recognized.

As a result, in many high-rise buildings, curtain-wool-shaped outer walls become mainstream, and the balcony (B) and the waist wall (W) disappear and the space becomes wider.

Apartment houses without a balcony (B) or curtain wall type buildings are the main cause of the use of air conditioners with high power consumption because sunlight enters the house without filtration in the summer and the temperature rises. Since electric power must be secured at peak, the use of summer cooling equipment, which consumes the largest amount of electric power, is economically disadvantageous and environmentally generates a large amount of carbon dioxide. Therefore, in recent years, prevention of global warming by energy saving and reduction of carbon dioxide generation is becoming a global problem, effective measures for reducing the use of cooling devices are needed.

The method of shutting off the sunlight is as follows: (1) a method of shutting off sunlight from the outside using a balcony or a shade, (2) a method of shutting off the room using a curtain or a blinking light, (3) low-E), or a method of cutting off a window or window using a double window provided with a special glass or blind inside the window. Among them, the most effective method for suppressing an increase in indoor air temperature due to sunlight is a method of originally shutting off from the outside of (1). In addition, in the case of (2) and (3), there is an advantage in that the view for the view is blocked in order to block the sunlight, but in the case of (1), the sunlight can be blocked without blocking the view for the view.

The easiest way to shut out the sunlight outdoors in a flat or curtain wall-type building without balconies is to install the awning. (1) The awning type awning has advantages such as low cost and easy installation, but it has drawbacks such as durability deterioration and appearance problems, and lowering of safety due to influence of horizontal loads such as wind due to high-rise of apartment buildings. (2) The louver-type shade is suitable for high-rise building or curtain wall type because it has a beautiful appearance and less influence of wind, but its use is low due to low recognition rate.

However, all conventional louver systems have been developed for the purpose of application to buildings constructed after 2008, when the requirement of installing sprinklers and fireproof glass is enacted, and it is inconvenient that it is difficult to apply to existing buildings because fire protection is not specially considered. It was pointed out.

This is because the louver is open vertically for the purpose of shutting off the sun without being affected by the wind and there is no blocking ability like the balcony (B) when the flame is moved to the upper layer by riding the outer wall of the building .

As shown in FIG. 2, in recent years, there is no actual balcony (B), and a large number of flames have occurred due to the flames moving to the upper layer. In particular, there is always a risk for high- Measures are required.

FIG. 3 is a view of the registered patent 10-1096681 previously filed and registered by the inventor of the present invention.

As an alternative to the conventional balcony function, the present inventor developed a louver having a fire preventing function which is effective for mining by blocking the sunlight without being influenced by the wind, and for blocking the flame to move to the upper layer in case of fire Closed louver device ', Patent No. 10-1096681).

The present invention is characterized in that in the louver system, the blades are normally laid to block the sunlight and, in the event of a fire, the blades are laid out and overlapped to prevent the flame from moving to the upper layer. The pusher pushes the blade by the elastic force of the spring as the fuse is broken in the event of a fire and is closed by rotating the stopper. At the same time, the stopper comes into contact with the blade, To prevent the blades from being opened by the blower so that the fire function is enabled.

However, in the case of the above-described invention, since the stopper of the central control panel acts as an out-of-plane load at the center of the blade in order to suppress the rotation of the blade during the fire, there is a possibility that the blade is deformed by bending due to the bending moment. That is, there is a disadvantage in that the blade is limited in length because it requires a sufficient resistance capability (shortening the length or increasing the cross-section) against the out-of-plane load, which is economically disadvantageous.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the related art. The purpose is as follows.

First, it is intended to provide an automatic closing louver system for fire prevention which automatically blocks the flame of the lower layer which is going to be transferred from the curtain wall type building without balcony to the upper floor in case of fire, without using electric energy.

The automatic closing louver device for fire protection according to the present invention is a louver device installed on a wall surface or outside of a window (WD)

A front fixing rod 320 having protrusions 322 formed on both sides of the rear end thereof; A rear fixing bar 340 having protrusions 342 formed on both sides of the front end thereof; A main body 310 having a bottom opened and having a fuse chamber 311 formed therein and a slot 312 and a projection 313 formed on both sides thereof; A plurality of blades (not shown) hinged to hinge devices 202, 202 ', and 203 so that a blade rotating shaft 201 protrudes at both ends in a shape of a plate and the lower blade 220 is rotatable on the main body 310 200); A front plate 120 having a front fixing bar insertion hole 122 formed at the center thereof and having a front end of the front fixing bar 320 inserted into the front fixing bar insertion hole 122; A rear plate 130 having a rear fixing bar insertion hole 132 formed at the center thereof and a rear end of the rear fixing bar 340 inserted into the rear fixing bar insertion hole 132 together with the elastic body 350; A plurality of blade rotation shaft insertion holes 111 are formed in a row at predetermined intervals so that the blade rotation shaft 201 can be inserted and rotated and the front end and the rear end of the blade rotation shaft insertion holes 111 are connected to both ends of the front plate 120 and the rear plate 130 Two side plates 110 attached to the side plates 110; And a fuse 330 inserted into the fuse chamber 311,

The protrusion 322 and the protrusion 342 are coupled to the slot 312 and the protrusion coupling portion 313, respectively. When the protrusion 322 is positioned at the front end of the slot 312, When the fuse 330 contacts the fuse 330 in a state where the fuse 330 is mounted between the rear end of the front fixing bar 320 and the front end of the rear fixing bar 340 of the fuse 330, And the combined body of the rear fixing bar 340 and the main body 310 is moved forward by the elastic body 350 to form a firewall that rotates and closes the blade 200.

The automatic closing louver system for fire protection according to the present invention is roughly divided into a control unit 300, a blade 200 and an outer frame 100.

The outer frame 100 includes the front plate 120, the rear plate 130, and the two side plates 110.

The outer frame 100 is preferably made of steel coated with an anticorrosive paint and a refractory coating in consideration of appearance, durability, structural safety, and fire resistance, and is required to have a cross- For lighter weight, it is also possible to drill like a rib on an airplane wing.

The control unit 300 includes the front fixing bar 320, the rear fixing bar 340, the main body 310, and the elastic body 350,

The elastic body 350 preferably provides a whole driving force of the controller 300 in the event of a fire, and it is preferable that a spring strong against heat is used.

When a conventional length adjusting device (not shown) such as a bolt / nut type is attached to the front fixing bar 320 or the rear fixing bar 340 so as to adjust the length of the front fixing bar 320 or the rear fixing bar 340, Can be adjusted to an effective mining angle depending on latitude and season. The same effect can be obtained by adjusting the length of the slot 312 or adjusting the positions of the protrusions 322 and 342 or the protrusion coupling portion 313.

The material of the blade 200 is most preferably an iron coated or coated with an anti-rust and refractory material such as the outer frame 100. In order to improve the fire resistance, a material resistant to heat such as ceramic is applied to the rear surface of the blade 200 It is preferable to use them in a superimposed manner.

The fuse 330 is inserted into the fuse chamber 311 and is broken at a certain temperature by the heat F. The fuse 330 may be a glass bulb or a fusible link used in a sprinkler that is broken at a temperature higher than a predetermined temperature in the event of a fire.

FIG. 7 is a cross-sectional view showing a state in which the control unit controls the blade in the normally open state of the automatic closing louver system for fire protection according to the present invention, and FIG. 8 is a cross- Sectional view showing a state in which the blade is controlled.

7 and 8, the front fixing bar insertion hole 122 and the rear fixing bar insertion hole 132 are inclined at an upper surface of the front fixing bar insertion hole 122 and the rear fixing bar insertion hole 132, The rear fixing bar 340 is moved forward by the elastic body 350 so that the front end of the rear fixing bar 340 and the rear end of the front fixing bar 320 enter the fuse 330 when the fuse 330 is broken. So that the main body 310 is lifted up.

The upper surface of the front fixing bar insertion hole 122 and the upper surface of the rear fixing bar insertion hole 132 must be inclined in order to raise the main body 310. [ That is, the front fixing bar insertion hole 122 secures a clearance where the front end of the front fixing bar 320 flows obliquely, and the rear fixing bar insertion hole 132 is formed at a position where the rear end of the rear fixing bar 340 flows obliquely .

The front plate 120 and the rear plate are further formed with protruding blade lower fixing protrusions 121 and blade upper fixing protrusions 131 facing each other so that when the blade 200 is closed, The lower blade 220 of the foremost blade 200 is hermetically sealed by abutting against the blade lower fixing jaw 121 and the upper blade 210 of the last blade 200 is fixed to the upper blade It can be brought into contact with the jaw 131 to be sealed.

At this time, due to the elastic force of the elastic body 350, the main body 310 pushes up and fixes the lower portion 220 of the blade, so that the blade 200 that is once closed is not opened by an external force such as a wind or wind.

8, the blade upper part 210 of the blade 200 is bent backward and the blade lower part 220 is bent forward to form an S-shaped cross section of the blade 200 as a whole, 200 is closed, the front blade upper portion 210 is abutted against the rear blade lower portion 220 to be sealed.

In other words, the blade 200 can be formed in various shapes such as a plate shape as a whole, a square shape or an elliptical shape (hereinafter, referred to as a planar shape), but the S shape shape shown in FIGS. Most preferred. This is economical because it can maintain high efficiency of lightening even if the distance between the blades 200 is widened. It is possible to close the blades 200 at a rotation angle smaller than that of the flat type at the time of closing for the fire, This is because it can increase. It is also desirable to make the blade 200 slightly rearward from the vertical in order to facilitate the rotation of the blade 200, which is also effective for mining.

As shown in FIG. 6, the hinge apparatuses 202, 202 ', and 203 of the present invention include an upper tube 202' installed at a lower end of the blade 200; A lower tube 202 installed on the upper portion of the main body 310; And a U-shaped fastener 203 connecting the upper pipe 202 'and the lower pipe 202. As shown in FIGS. 7 and 8, when the main body 310 is moved, The center axis of the upper tube 202 'and the center axis of the lower tube 202 are different from each other to secure a clearance, and corresponding hinge joints are generated.

3, when the blade 200 is closed, the blade pusher 362 pushes up the blade lower portion 220, so that the blade pusher 362 and the blade lower portion A strong concentrated load is generated at the contact portion of the blade 220, and thus the blade 200 is bent. Accordingly, the present invention is characterized by providing an automatic closing louver for fire protection, which is economical by eliminating an out-of-plane load which limits the length of a blade, which is a disadvantage of the prior art 10-1096681, and which has a fire function optimally applicable to windows.

FIG. 9 is a conceptual diagram showing a state in which the direction of the flame is controlled according to the open and closed states of the blades in the multi-story building provided with the automatic closing louver system for fire prevention of the present invention.

The blade 200 is normally opened as shown in FIG. 9 (a), and as shown in FIG. 9 (b), when the fuse 330 is broken during a fire, The blade 200 is closed by the upward movement of the door 310 so that the automatic louver system for fire prevention of the present invention functions as a firewall as a conventional balcony as a whole and prevents the flame F of the lower layer from spreading to the upper layer.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

It is therefore intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
