Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a heat shield shutter for construction, which can block the heat in the event of a fire.

[Problems to be Solved by Related Art and Invention] In buildings such as buildings today, when a fire occurs, a fire prevention shutter is lowered to prevent the spread of fire. Accordingly, fire resistance is imparted to a shutter curtain of this type of fireproof shutter by using a metal shutter slat. However, since the slatt is made of metal, it has a high thermal conductivity, and therefore the heat of the fire spread side is transferred almost as it is to the non-fire spread side where the fire spread shutter stops the fire spread, and as a result, the non-fire spread side also has a shutter curtain. In the vicinity, it becomes a fairly high temperature, and the radiant heat causes wood, paper,
Alternatively, if flammable substances such as plastic products are located nearby, it is possible that these substances may ignite and prevent the spread of fire.

Therefore, it has been proposed to attach a heat shield plate to the slat. Conventionally, in attaching the heat shield plate, a plate member 8 is integrally fixed to the slat 2 to form a follow type as shown in FIG. The heat shield plate 9 was housed in. However, in this case, the step of attaching the plate material 8 is not required separately, and in the event of a fire, the thermal expansion between the slat and the plate material differs due to the temperature difference between the fire spread side and the non-fire spread side,
As a result, a new problem occurs that the shutter curtain itself is deformed and the fireproof performance is impaired, and it cannot be immediately adopted.

[Means for Solving the Problems] The present invention has been made in view of the above circumstances and was devised for the purpose of providing a heat shield shutter for buildings that can eliminate these drawbacks. To attach a heat shield plate to a shutter curtain configured by interlocking to make a heat shield shutter for construction, a locking hook is provided to project on one side edge of the heat shield plate,
The locking hook is locked to the interlock coupling portion so that the heat shield plate is hung so as to face the slat surface, while the slat facing surface of the heat shield plate is bonded to the slats by an adhesive means. Is.

With this configuration, the present invention makes it possible to easily and securely attach the heat shield plate to the existing shutter curtain, and also to eliminate the deformation of the shutter curtain in the event of a fire. Is.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a shutter curtain for a fire protection shutter, the shutter curtain 1 being a series of metal shutter slats 2 connected in series, and a shutter case arranged on the ceiling. 3 is wound around a winding drum 4 and the brake is released based on a detection command from a fire alarm (not shown), whereby the automatic shutter curtain 1 descends to form a fireproof section. The fact that it is configured to stop the spread of fire is the same as in the past.

The shutter slat 2 is formed with interlock portions 2a, 2b on both upper and lower edges, and is connected in a series by engaging the interlock portions 2a, 2b of adjacent slats. However, the interlock portions 2a and 2b are interlocked with each other and are separated from each other by a gap L with respect to the slat surface.

Reference numeral 5 denotes a heat shield plate, which is made of a non-combustible material having heat shield properties, such as fire bricks and inorganic foam.
A locking hook 6 is formed so as to project from the upper edge of the heat shield plate 5. Then, as shown in FIG. 3, in a state in which the locking hook 6 is in a substantially horizontal position, the locking hook 6 is fitted into the interlock connecting portion through the gap L, and is hung down so that the locking hook 6 engages with the interlock connecting portion. The heat shield plate 5 and the slat surface face each other. Then, the opposing surface parts are attached to each other with double-sided adhesive tape 7
It is attached integrally using.

In the embodiment of the present invention configured as described above, an emergency situation such as a fire occurs, and the shutter curtain 1 descends in connection with the detection operation of the fire alarm to form a fireproof section. Since the heat shield plate 5 is attached to the slat 2 constituting the shutter attenuator 1, the heat shield plate 5 has excellent heat shield properties, and the ignition phenomenon due to the radiant heat on the non-fire spread side can be surely suppressed.

In this way, the heat shield plate 5 exhibits an excellent heat shield effect on the non-flame spread side. However, the heat shield plate 5 has the engagement hook 6 engaged with the interlock portion and the slat 2. Since it is affixed with a double-sided adhesive tape 7, it is integrated with the slat 2 in normal times, and as a result, the heat shield plate 5 has no obstacle even though it has the heat shield plate 5. Never.

Then, when a fire occurs, the adhesive tape 7 burns and the shield plate 5 separates from the slat 2, but the heat shield plate 5 has the heat shield performance because the engagement hook 6 is engaged with the interlock portion. There is no loss. In addition, the heat shield performance of the shield plate 5 can be exhibited, but the slat 2 is
There is no problem that the shutter curtain is rejected due to the difference in thermal expansion between the inside and outside like the conventional one that houses the heat shield in the follow type, and there is no distortion as in the case of a single sheet type slatt. Excellent fireproof performance.

Moreover, in this case, since the heat shield plate 5 is attached by inserting the locking hook 6 through the gap L of the interlock portion, the heat shield plate 5 can be easily attached to the existing slats, and therefore, Since heat shielding performance can be added to the existing shutter as well, it is not preferable from the standpoint of disaster prevention, and the shielding plate 5 can be replaced if necessary, and it also has a pattern changing function.

Needless to say, the present invention is not limited to the above-mentioned embodiment, and the adhesion between the slats and the shielding plate is not limited to the double-sided adhesive tape, but may be performed using an adhesive, and the locking hooks may be used. From the standpoint of construction, it is preferable to lock the interlock part to the interlock part by fitting the locking hook into the interlock part through the gap L of the interlock part, but the invention is not limited to this. Of course, it may be inserted from the end of the slatt.

[Effects] In summary, since the present invention is configured as described above, the heat shield plate attached to the slats provides excellent heat shield properties, and the ignition phenomenon caused by radiant heat on the non-fire spread side. However, since the heat shield plate is held in a hanging state with the locking hooks locked to the interlock part, and the facing surfaces of the shield plate and the slats are bonded together. The shield plate is normally integrated with the slats, and as a result, the heat shield plate does not move and interfere with the heat shield plate even if it is suspended.

When a fire occurs, the adhesive burns and the shield plate separates from the slat, but the heat shield plate is held in a hanging state in which the locking hook 6 is locked in the interlock part.
The heat shield performance is not impaired at all. Moreover, the slats do not have the problem that the shutter curtain is distorted due to the difference in thermal expansion between the inside and outside, like the conventional one that stores the heat shield plate in the follow type, and it is the same as in the case of one-piece slats. It is possible to demonstrate excellent fire resistance without distortion.
