Description

The present invention relates to the technical field of a mounting structure for a sleeve in a fire prevention sliding door device provided for opening and closing an opening in which a doorway or the like is formed in a building.

Generally, in order to open and close entrances and exits provided in structures such as buildings, sliding door devices are sometimes installed in which the door body can be opened and closed in the left and right directions. The opening is provided with a doorway section that opens and closes when the door body moves in the left and right direction, and a sleeve section (fitting door) that is adjacent to the door end side of the doorway section and overlaps the door body in the open position. There is a structure in which the door body overlaps the sleeve portion back and forth when the door body is opened and moved. In such a sliding door device, the sleeve plate (mirror plate) provided on the sleeve is made of a translucent material such as a glass plate, so that even the sleeve portion has translucent properties. In some cases, the opening structure has a wide image, and if a sliding door device with such a sleeve part is to be provided with fire retardant performance, it is required that the sleeve part also be provided with fire retardant performance.
By the way, such a sleeve part consists of a stile frame that is supported by the frame with frame materials on all four sides (four circumferences), top, bottom, left and right (door end side, door end side), and a frame that is built into the frame frame. In order to make these sleeves fireproof, each frame is made of a metal material with excellent heat resistance and fireproofing performance (for example, steel or stainless steel). It is proposed that the sleeve plates be formed using, for example, fireproof glass that has heat resistance and fireproofing properties and is translucent.
If the sleeve section is provided with fireproof performance in this way, the sleeve section will thermally expand when it receives the heat that occurs when a fire occurs, but in this case, the vertical frame material will be Because the vertical frame is supported by the ceiling and floor, there is virtually no room to absorb vertical displacement when the vertical frame material expands thermally. At times, they tend to bend and deform, and there is a fear that this bending and deformation may cause a gap to occur between the vertical stile material and the sleeve plate, thereby impairing fire protection performance.
On the other hand, in forming such a sleeve part, the upper horizontal frame material is fitted into the upper horizontal frame material (open, upper frame) provided on the body side in an open shape in an upwardly displaceable state. There is a structure (for example, see Patent Document 1), and it has been proposed that this technology be adopted in a fire prevention sleeve structure to absorb vertical displacement when the vertical frame material thermally expands.

The upward movement of the upper horizontal stile member 12 can be set, for example, until the upper edge 17d of the rising piece 17c comes into contact with the front half 4i of the lower piece.

Next, a procedure for attaching the sleeve portion 3 configured in this manner to the opening will be described. As the sleeve part 3, the frame X in the state before the sleeve board 16 is installed is assembled, and then the sleeve board 16 is installed. It is assumed that the members 12c and 13c have been removed, and that the rear clamping piece 18 of the upper horizontal frame member 4 has been removed. Then, the frame X without the sleeve plate 16 and the removable edge members 12c and 13c is placed under The stile main body portion 13a of the horizontal stile material 13 is externally fitted onto the lower rail material 5a, and the door end side vertical stile 15 is internally fitted into the fitting groove 7a of the door end side vertical frame material 7.
Thereafter, with the supporting member rising piece 17c in contact with the lower half 4n of the front clamping piece, the lower horizontal stile body 13a is fixed to the lower rail 5a via the screws 13e, and the door is closed. The rear vertical stile 15 is fixed to the door vertical frame member 7 via screws 15d, and the rear clamping piece 18 is in a state where the lower piece 18c abuts the support member rising piece 17c from the rear side. and fix it to the rear half 4j of the lower piece 4e of the upper horizontal stile material via the bolt 18b. By doing this, after the sleeve plate 16 is moved back and forth in the left and right direction and incorporated into the frame frame X that has been attached to the opening side, the removable edge members 12c and 13c are attached. By fixing it to the horizontal stile members 12 and 13 via screws 12d and 13d, the sleeve portion 3 can be attached to the frame side.

In this embodiment configured as described above, the frame opening has a doorway E that opens and closes when the door body 2 moves in the left-right direction, and a doorway E that is adjacent to the door end side of the doorway E and is in an open position. In the case where the door body 2 is provided with a sleeve portion 3 that overlaps in the front and back, the sleeve portion 3 is formed by horizontal frame members 12, 13 on both upper and lower sides, and vertical frame members 14, 15 on the door end side and the door end side. A frame constructed by incorporating the sleeve plate 16 into the frame frame 8 having a four-circumferential frame will be incorporated into the opening. Since the upper horizontal frame member 12 is assembled with a gap S that allows upward movement relative to the upper horizontal frame member 4 constituting the opening, the door edge side vertical frame member 12 will be damaged by the heat generated during a fire. The upward movement of the upper horizontal stile material 4 due to the expansion of the door frame 6 is absorbed, thereby preventing the vertical stile material 6 on the door end side from deforming, and exhibiting high fire prevention performance. In this case, a rear clamping piece 18 is incorporated into the upper horizontal frame member 4 from the front-back direction as a support means for supporting the incorporated upper horizontal frame member 12 in a state that allows upward displacement. As a result, the sleeve portion 3 can be easily assembled in a state that allows upward displacement of the upper horizontal stile member 12, and work efficiency is improved.

Furthermore, in this case, the support that allows the upward movement of the upper horizontal stile member 12 is provided by providing the support member 17 with the rising piece 17c that rises upwardly on the upper side horizontal stile member 12. Since support for allowing this is provided by the front and rear clamping pieces 4k and 18 that support both the front and rear sides of the rising piece 17c, the support structure for the rising piece 17c becomes simple.
Furthermore, in this case, since the rear clamping piece 18 of the clamping pieces 4k and 18 is removably attached to the upper horizontal frame member 4, the lower horizontal frame member of the sleeve part, The support and fixation of the vertical stile material on the door end side to the frame side can be done by fixing with screws, and the work of attaching the sleeve portion to the frame side is facilitated.
