Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is designed to prevent smoke from falling from a ceiling of a room by a smoke detector or the like when a fire occurs in the interior of various buildings such as concrete. The present invention relates to a flange member for preventing the smoke curtain from coming off from the left and right guide rails due to wind pressure, for preventing the smoke curtain from moving to another adjacent room.

(Prior Art) At present, this type of smoke proof screen is normally moved up and down with the left and right edges of the smoke proof screen being only inserted into the left and right guide rails. However, in this case, a fire breaks down the smoke screen, and as the fire spreads, wind pressure is generated on the smoke, and the smoke moves away from the guide rails by the wind force, causing the smoke to move quickly into the adjacent room. However, there is a drawback that the smokeproof effect is extremely poor.

(Problems to be Solved by the Invention) The present invention was devised in order to solve the above-mentioned conventional drawbacks, and the purpose of the present invention is to prevent wind pressure generated by a conventional smokeproof screen during a fire. Therefore, there is a problem that the smoke-proof effect cannot be achieved because the smoke easily moves away from the guide rail. Therefore, we are going to provide a brim metal fitting to completely prevent the smoke curtain from coming off by fixing the brim to the edge of the smoke curtain that has been inserted in the guide rail in advance by a simple operation. is there.

(Means for Solving Problems) In order to achieve the above-mentioned object, a plurality of detachment-preventing brim fittings are attached to the left and right sides of the smoke-proof screen (2) and are attached to the ends thereof to prevent the detachment. Of the bending clamps (7) (7) (7) (7) In 7), a cut-and-raised piece (8) is formed on one side, and a cut-and-raised piece (8) is formed on the other side.
An insertion hole (9) for inserting is inserted. And
The smoke proof screen (2) is inserted and fixed at the left and right edges between the bent holding pieces (7) and (7).

(Operation) The present invention is configured as described above, and the attachment method is as follows. Plural brim metal fittings (5) (5) ... are fixed to the left and right edges of the smoke screen (2) at regular intervals. . Then, the guide rails (4) and (4) fixed or rotated on the ceiling part are fitted into the guide rails (5) and (5) from above to guide rails (4).
It goes up and down without being detached from the bent pieces (20) (20).

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.
In the figure, a winding cylinder (1) is fixed to a central winding shaft (11), and is vertically mounted on a storage case (17). The smoke screen (2) is made of a constituent material such as woven fabric having excellent heat insulation and fire resistance, and the upper part of the smoke screen (2) is attached to the winding cylinder (1) and the lower part is relatively It is inserted into the seat body (3) having a rectangular cross section provided with the sandwiching pieces (18) (18) and is fixed by the attachment element (19). The left and right ends of the smoke screen (2) are attached to the ceiling member (1
Guide rails (4) (4) that are movable or fixed in a fixed position in 6)
It is designed to be inserted into and moved up and down. Then, from the bent pieces (20) (20) provided on the guide rails (4) (4), a plurality of brim fittings (5) are fixed at regular intervals on both left and right edges of the smoke screen (2). It is prevented from detaching.

Next, as shown in FIG. 4, the flange member (5) is provided with a retaining flange (6) at one end thereof. Bending and sandwiching pieces (7) and (7) connected to the collar portion (6) and facing each other at right angles are formed. The bent holding piece (7) (7) has a cut-and-raised piece (8) formed on one side, and the cut-and-raised piece (8) on the other side.
An insertion hole (9) for inserting and bending is formed. Further, an end edge of the smoke proof screen (2) is interposed between the bending holding pieces (7) and (7) as shown in FIG. 6, and the bending holding pieces (8) are provided with the cut and raised stop pieces (8).
(7) It is designed to be fixed to (7). Reference numeral (10) indicates an adjustment curtain portion for appropriately adjusting the size of the seat body (3), which is excessively inserted and housed.

Further, on the upper part of the winding case (17), the drive machine (13) is fixed to the shaft of the electric motor (12), and the driven wheel (15) is fixed to the end of the winding cylinder (1), A transmission chain (14) is installed between the drive machine (13) and the driven wheels (15).

(Effect of the Invention) Since the present invention is configured as described above, according to the brim metal fitting used for this smokeproof screen, both ends of the smokeproof screen can be safely and reliably lifted up and down without separating inside the guide rails. It has an excellent effect of preventing the movement of heavy smoke as much as possible without causing both ends of the smokeproof screen to be detached from the guide rails even against a strong wind pressure caused by a fire. Further, the flange member is provided with a retaining flange at one end, and is provided with opposed bending clamp pieces that are connected to the flange and bent, so that one thin metal piece is used for production. Since it can be easily formed only by bending, it has an effect that it can be mass-produced easily and provided at a low cost. Further, since the cut-and-raised piece is provided on one side of the bending-holding piece and the insertion hole into which the cut-and-raised piece is inserted and bent is formed on the other side, the cut-and-raised piece can be easily inserted and opposed to each other. There is an effect that the sandwiching pieces can be easily coupled and that the smokeproof curtain can be sandwiched and fixed only by inserting the end edge of the smokeproof curtain between the bent sandwiching pieces. Further, the cut-and-raised piece can be fixed simply by bending the tip of the cut-and-raised piece with respect to the other bent sandwiching piece, which is a very convenient effect because it is not necessary to use a conventional attachment such as a bolt and nut. .
