JP 2004-293085 A

Recently, safety for fires is required in the opening and closing windows, and it is necessary to provide a fire prevention function. Therefore, in the open / close window, a thermal expansion material is disposed between the shoji frame of the window and the frame, and the thermal expansion material is expanded in the event of a fire to fill the space between the frame and the shoji so To prevent the intrusion of flames and smoke.
However, in the sliding window etc. which are seen in the said patent document 1, a comparatively big space arises between the cage | basket | cushion and frame | frame of a suspension origin side on the mechanism of a sliding window, and this space is filled with a thermal expansion material. However, it is difficult to close the space between the shoji fold and the frame with the thermal expansion material, such as a large amount of thermal expansion material is required for the expansion, and uneven expansion occurs.

  The present invention has been made in view of the above circumstances, and even in an opening / closing window in which a large space is formed between a sliding door such as a sliding window and a frame, the sliding door and the frame are formed by a thermal expansion material provided in the space in the event of a fire. An object of the present invention is to provide an opening / closing window capable of closing the body.

The present invention comprises a shoji and a frame, and a piece facing the indoor side surface or the outdoor side surface of the shoji pod facing when closed is provided on the indoor side or outdoor side of the frame, and on the outer peripheral surface of the shoji ridge. , A projecting piece projecting in the longitudinal direction toward the inner peripheral surface of the frame body opposed at the time of closing is provided, and a space between the outer peripheral surface of the shoji ridge and the inner peripheral surface of the frame body is separated from the frame piece and It is characterized by being divided by the protruding piece of the shoji bowl, and a thermal expansion refractory material is arranged in the compartment.

  According to the present invention, for example, even in an open / close window in which a relatively large space is formed between a shoji sash and a frame, such as a sliding window, the shoji slab is formed by a thermal expansion material provided between the shoji and the frame in the event of a fire The space between the frames can be efficiently blocked in the indoor and outdoor directions.

Is configured.
The shoji 3 is configured to be opened and closed by a handle fixed to the door rod 33 of the shoji 3.

(Fireproof structure with thermally expanded refractory material)
As shown in FIGS. 4 and 5, between the prospective surfaces of the upper frame 21 and the lower frame 22 of the opening / closing window W and the prospective surfaces of the upper collar 31 and the lower collar 32, the extending portions 211 c of the outer shape materials 211 and 221 are provided. , 221c, the upper auxiliary material 214, and the lower auxiliary material 224 form spaces S1, S2, and the outer side surfaces of the upper auxiliary material 214 and the lower auxiliary material 224 and the outer shape materials 211, 221 extend in the spaces S1, S2. Thermal expansion refractory materials 51, 52, 53, and 54 are disposed on the indoor side surfaces of the installation portions 211c and 221c.

  In the event of a fire, the thermally expanded refractory materials 51, 52, 53, 54 expand and fill in the spaces S1, S2, so that the toxic gas generated during the combustion of the connecting material is reliably trapped inside the fire door body 1. Thus, the indoor and outdoor communication between the upper frame 21 and the lower frame 22 and the upper rod 31 and the lower rod 32 can be prevented.

On the other hand, as shown in FIGS. 6, 7, and 8, the shoji bracket 42 and the second link constituting the opening / closing mechanism 4 are provided between the prospective surfaces of the vertical frames 23 and 24 and the door-end rod 33 and the suspension rod 34. A relatively wide space is required due to the fact that the suspending side of the arm 44 protrudes from the prospective surface of the suspending rod 324 to the outer peripheral side and the influence of the opening and closing track of the shoji 3, etc. Therefore, the prospect of the vertical frames 23 and 24 is required. Many thermal expansion materials were required to fill the space between the surface and the door rods 33 and the suspension rods 34 with the thermal expansion material. Further, there is a risk that unevenness occurs due to expansion in a wide space and a gap is generated.
In particular, in the space on the suspending side where there is no member to which the thermal expansion refractory material such as the lock pin 48 or the lock piece 49 is caught, the refractory material expanded between the vertical frame 24 and the suspending rod 34 falls down. There was a possibility that a gap would occur.

Therefore, a protruding piece 345 that protrudes in the longitudinal direction toward the outer peripheral direction is provided on the outer peripheral side surface of the suspension base 34, and the extended portion 241 c of the outer shape member 241 of the vertical frame 24 and the protruding piece 345 A space S <b> 3 that is continuous with the connecting member 243 is defined between the hanging rod 34 and the vertical frame 24.
And the thermal expansion refractory material 56 is arrange | positioned so that the connection material 243 may be covered in the prospective surface of the vertical frame 24 in space S3.

  As a result, in the event of a fire, the thermal expansion refractory material 56 expands in the space S3 that is narrowly defined by the extending portion 241c of the outer shape material 241 and the protruding piece 345, and is generated when the space S3 is filled and the connecting material is burned. It is possible to prevent the toxic gas to be trapped inside the fire door main body 1 and to be released to the outside, and to block the communication between the vertical frame 24 and the suspension rod 34.

  Further, the protruding piece 345 protruding into the space between the hanging rod 34 and the vertical frame 24 itself has an effect of preventing indoor and outdoor communication at a wide interval between the hanging rod 34 and the vertical frame 24. Further, when the shoji 3 is warped due to heat at the time of fire, the shoji 3 is curved to the warp preventing piece 242d provided in the inner circumferential direction on the inner circumferential surface of the vertical frame 24 on the hanging base side. The projecting piece 345 of the hanger base 34 is brought into contact, and the generation of a gap due to warping can be suppressed.

  As described above, the protruding piece 345 that protrudes in the longitudinal direction toward the outer peripheral direction is provided on the outer peripheral side surface of the suspension base rod 34, and the extended portion of the outer member 241 of the protruding piece 345 and the vertical frame 24. A space S3 is formed by partitioning the suspension frame 34 and the vertical frame 24 generated when the open / close window W is closed by the 241c, and the thermal expansion refractory material 56 is provided in the space S3. The expanded refractory material can be expanded and filled in a small partitioned space S3, and the toxic gas generated during the combustion of the connecting material can be confined in the fire door body 1 and prevented from being released to the outside. In addition, the indoor / outdoor communication between the vertical frame 24 and the suspension base 34 can be prevented.

  Furthermore, since the prospective surface portion 242c of the inner shape member 242 of the vertical frame 24 on the hanging side of the opening / closing window W is provided with a warp prevention piece 242d toward the inner peripheral direction, even if the shoji 3 is warped during a fire. The protruding piece 345 protruding into the space between the hanging rod 34 and the vertical frame 24 can abut against the warp preventing piece 242d to prevent further warping, and a gap due to warping of the shoji 3 is generated. Can be prevented.

  In the above embodiment, the vertical sliding window provided in the fire door is illustrated as the opening / closing window, but the place where the opening / closing window is installed and the method of the opening / closing window are not limited. It can be used for an open / close window provided in a bathroom or other room, and can be used for any type of window as a technique for sealing a space between a window frame and a shoji with a thermal expansion material.
