Description

WALL-THROUGH SCREEN FIREPROOF SHUTTER}

The present invention relates to a wall-through screen fire shutter. More specifically, when a screen fire shutter without an emergency exit operates and descends in a fire situation, the situation on the other side of the screen fire shutter is visually checked through an observation window and the fire screen is opened. It is about wall-through screen fire shutters that can be torn off to escape the fire zone.

In general, screen fire shutters inside a building are configured to automatically operate and close the fire scene in the event of a fire to prevent the spread of combustion and smoke within the building. In this way, people who were unable to evacuate while the fire area was blocked with a fire screen were able to escape by opening the emergency door installed in the center of the fire screen.

However, because the conventional emergency door opens in a triangular shape with a narrow opening width at the top due to an inclined hinge installed at the bottom of the emergency door, there was a problem in that many people were unable to escape quickly when escaping through the emergency door. In addition, due to the weight of the emergency door, there was a problem that it was difficult for the elderly or children, who were relatively weak, to open the emergency door.

Additionally, there was a problem with the fire spreading to a safe area through the emergency door because the emergency door did not close after people evacuated through the emergency door.

In order to solve the problem of emergency doors installed on screen fire shutters not functioning properly in the event of a fire, the fire protection regulations related to screen fire shutters were recently revised to prohibit the installation of emergency doors on fire screens.

However, if the fire screen does not have an emergency door, there is still a problem that it is not easy for people to safely escape from the fire area. Accordingly, there is a growing need for screen fire shutters that effectively block the spread of fire and at the same time provide the minimum means for people to escape to a safe place from fire.

The present applicant proposed the present invention to solve the above problems.

The cutting part (CL2-1) of the cutting line (CL2) is a part that allows evacuees to easily tear the fire screen 110, and the connection part (CL2-2) is a part where the fire screen 110 is connected to the weight member at the bottom 116. This is the part that supports weight and maintains its original function.

It is preferable that the cutting portion (CL2-1) of the cutting line (CL2) is formed longer than the connecting portion (CL2-2).

Meanwhile, the cutting guides CL1 and CL2 may include a cutting guide line CL1 that is printed or marked on the surface of the fire screen 110. Unlike the cutting line CL2, the cutting guide line CL1 may be printed on the surface of the fire screen 110 without cutting the fire screen 110.

In an emergency, evacuees can push the cutting line (CL2) with their hands to break the connection (CL2-2), creating a gap, and evacuate through the gap. However, if the connection part (CL2-2) is not sufficiently broken or the cutting line (CL2) is difficult to pass through the torn gap, a cutting means (170, see FIG. 10) such as a knife or cutter is used. You can also use it to evacuate after cutting the connection part (CL2-2) or cutting guide line (CL1).

In this way, the cutting guide line CL1 can guide the evacuee to the location of the part of the fire screen 110 that needs to be cut using the cutting means 170. If an evacuee cuts a part where the cutting guide line (CL2) is not marked, they can evacuate, but they cannot prevent flames or smoke from spreading through the cut part. This is because the first and second auxiliary screens 120 and 140 are provided only at positions that can cover the cutting guide parts CL1 and CL2.

Meanwhile, the cutting guide portions CL1 and CL2 formed on the fire screen 110 may be provided with only a cutting line CL2 without a cutting guide line CL1.

As described above, the wall-through screen fire shutter 100 according to an embodiment of the present invention includes the fire screen 110 woven in the up and down direction or metal threads (W1, W2) woven in the up and down and left and right directions. Because of this, the metal threads W1 and W2 can support the load of the fire screen 110 or the weight member.

Even if the cutting guides (CL1, CL2) are provided with only the cutting line (CL2), the metal threads (W1, W2) support the weight of the fire screen 110 or the weight member to some extent, so they are aligned along the cutting line (CL2). It is possible to prevent the fire screen 110 from tearing on its own.

Referring to FIG. 6, some (W2, inclined) of the metal threads (W1, W2) included in the fire screen 110 are provided in a direction parallel to the cutting portion (CL2-1), and the metal threads (W1, W2) Another part (W1, weft) may be provided in a direction that intersects the cutting portion (CL2-1).

Here, it is preferable that the metal threads W1 and W2 are not present in the cutting portion CL2-1 or are provided in a broken state. In an emergency, when a evacuee pushes the part marked with the cutting guides (CL1, CL2), the connection part (CL2-2) is torn and the torn part is connected to the cutting part (CL2-1), creating a gap through which an escape can occur. It must be made at (110). However, if there are metal threads (W1, W2) in the cutting portion (CL2-1), a gap through which the metal threads (W1, W2) can escape may not be created. Therefore, it is preferable that the cutting portion CL2-1 is provided with no metal threads W1 and W2 or in a broken state. If there are metal threads (W1, W2) in the cutting portion (CL2-1), notches, etc. are formed on the metal threads (W1, W2) exposed to the cutting portion (CL2-1) so that they can be easily broken. It is desirable to form

On the other hand, the metal threads W1 and W2 may be connected to the connection part CL2-2. Since the connection part (CL2-2) also serves to support the weight of the fire screen 110 or the weight member to some extent, the metal threads (W1, W2) are left in the connection part (CL2-2) to support the weight member, etc. Can support weight. At this time, by forming notches in the metal threads W1 and W2 located at the connection part CL2-2, the evacuee can easily break the connection part CL2-2.

As shown in FIG. 7, the cutting guide parts CL1 and CL2 may be formed in various places on the fire screen 110. If the width of the screen fire shutter 100 or fire screen 110 is long and the cutting guides (CL1, CL2) are formed in only one place, the evacuee must move to the position where the cutting guides (CL1, CL2) are displayed. However, due to the travel time, you may not be able to evacuate in time and you may waste time looking for the cutting guide (CL1, CL2). In order to prevent this problem, the wall-through screen fire shutter 100 according to an embodiment of the present invention may have cutting guide parts CL1 and CL2 provided at various locations on the fire screen 110. Additionally, by forming the cutting guides (CL1, CL2) in multiple locations, multiple evacuees can evacuate by tearing the cutting guides (CL1, CL2) at the same time.

Meanwhile, in the event of a fire, if the wall-through screen fire shutter 100 is lowered to the floor, evacuees (people) cannot know the situation on the other side of the screen fire shutter 100. This is because the fire screen 110 covers the other side. If the other side of the fire screen 110 is unsafe and a evacuee tears the cutting guides (CL1, CL2) of the fire screen 110 and goes to the other side, it may be dangerous. Therefore, it is necessary for the evacuee to visually check the situation on the other side of the fire screen 110 and, if safe, tear off the cutting guides (CL1, CL2) and evacuate.

To this end, the wall-through screen fire prevention shutter 100 according to an embodiment of the present invention may include at least one observation unit 150 provided on the fire prevention screen 110.

Since the observation unit 150 is made of a transparent material, evacuees can visually check the situation on the other side of the fire screen 110.

At least one observation unit 150 may be provided on the fire screen 110, and may be provided at a position corresponding to the eye level of an adult, or may be provided at a position approximately 800 to 900 mm from the bottom of the fire screen 110. .

Although not shown, the observation unit 150 may also be provided on the first auxiliary screen 120 or the second auxiliary screen 140. When the observation unit 150 is provided on the first or second auxiliary screens 120 and 140, the observation unit 150 must also be provided at a corresponding position on the fire screen 110.

Referring to Figures 8 and 9, the observation unit 150 includes a window hole (H) formed through the fire screen 110; A window 151 provided to shield or cover the window hole (H); And fixing means (158, 159) for coupling the window (151) to the fire screen (110).

Here, since the window hole (H) is formed through the fire screen 110, it can be provided so that the fire screen 110 does not exist in the window hole (H).

The window 151 must be made of a transparent material so that evacuees can visually see the situation on the other side through the observation unit 150.

Additionally, the window 151 must be formed of a heat-resistant material. If the window 151 is deformed, such as melting or burning, due to a fire, evacuees will not be able to see the situation on the other side through the observation unit 150. Therefore, the window 151 must be formed of a transparent heat-resistant material. For example, the window 151 may be made of silica glass, which has a melting point of about 1,300°C.

By displaying a fluorescent or luminous material on the edge or perimeter of the window 151, evacuees can easily check the observation unit 150 even if the power goes out during a fire.

A plurality of through holes 113 penetrating the fire screen 110 are formed around the window hole (H), and at the edge of the window 151, a plurality of fastening holes 152 communicating with the through hole 113 are formed on the window ( 151) can be formed by penetrating.

The fixing means 158 and 159 may include a first fixing means 158 passing through the fastening hole 152 and the through hole 113, and a second fixing means 159 fastened to the first fixing means 158. Here, the metal thread (W) contained in the fire screen 110 exists in the through hole 113 but does not exist in the window hole (H). If there is a metal thread (W) in the window hole (H), there is a risk of obstructing the evacuee's view, so it is preferable that there is no metal thread (W) in the window hole (H).

The first fixing means 158 may be provided as a bolt, and the second fixing means 159 may be provided as a nut into which the bolt is inserted.

On the other hand, it is preferable that the through hole 113 has a metal thread (W). With the metal thread (W) passing through the hole 113 between the first fixing means 158 and the second fixing means 159, the first fixing means 158 and the second fixing means 159 are tightened together. The first fixing means 158 inserted into the through hole 113 can form a fastened state with the metal thread (W).

In this way, by providing an observation part 150 made of a transparent material on the fire screen 110, etc., evacuees can visually check the situation on the other side of the fire screen 110 through the observation part 150 and receive a cutting guide when safe. You can evacuate through (CL1, CL2).
