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.

However, since the above-mentioned conventional type simply inserts the frame material into the frame side member, the attachment strength of the sleeve itself to the frame side is not sufficient, and as a result, high temperature in the event of a fire occurs. When exposed to harsh or abnormal environments, there is a risk that the sleeve itself may bend prematurely or come off from the body, and other problems may occur, so it is necessary to maintain the necessary fire protection performance. There are problems in that it is difficult to do so, and these problems are the problems to be solved by the present invention.

The present invention was created with the aim of solving these problems in view of the above-mentioned circumstances, and the invention as claimed in claim 1 provides a mechanism for opening and closing an opening by moving the door body in the left and right directions. In a fire prevention sliding door device, the sleeve portion is provided with an entrance/exit portion and a sleeve portion adjacent to the door end side of the entrance portion and over which the door body in the open position overlaps. It is constructed by incorporating a sleeve plate into a frame frame framed by vertical frame materials on the side and door end sides, and when incorporating the sleeve portion into the opening, the upper horizontal frame material is attached to the upper horizontal frame provided in the opening. It is assembled in such a way that there is a gap in the wood that allows the upper horizontal stile to move upward as the vertical stile expands due to heat during a fire, and the lower horizontal stile is attached to the main frame. The vertical stile material on the door end side is supported and fixed on the body frame side and its displacement in the horizontal direction is regulated, and the vertical frame material on the door end side is not supported on the body frame side. The upper side frame member is provided with a support member having a rising piece portion rising upward, and the upper side frame member is provided with a support member having a rising piece portion that stands up upward. This is a mounting structure for a sleeve in a fire prevention sliding door device, characterized in that support means is provided for supporting the rising piece in a state that allows upward displacement of the piece .

In the door end side vertical stile material 15 configured in this manner, the stile main body portion 15a that fits into the groove-shaped fitting groove 7a formed in the door end side vertical frame 7 is connected to the door end side vertical stile material 15 through screws 15d. By being supported and fixed to the side vertical frame 7, displacement in the left-right direction is restricted.

Further, a front piece 4d is suspended from the front edge of the upper horizontal frame member upper piece 4a, and the vertical intermediate portion of the front piece 4d and the lower edge of the intermediate vertical piece 4c are different from each other. They are connected by a lower piece 4e. In addition, on the rear end side of the upper horizontal frame member 4, an inspection lid 4f is detachably attached to the support fittings 4o provided on the vertical frame members 6 and 7 via screws 4g, and by removing the inspection lid 4f, the upper horizontal The inside of the frame material 4 can be inspected and maintained.

Next, the relationship between the upper side frame member 12 and the upper side frame member 4 described above will be explained in detail. First, the lower piece 4e is formed into a step shape in which the front half 4i is high and the rear half 4j is low, with a vertical step portion 4h interposed therebetween, with the plate surface facing in the vertical direction. Further, a front clamping piece 4k is disposed below the front half 4i, and the front clamping piece 4k extends to the front with a horizontal step-shaped part 4l between which the plate surface faces in the left-right direction. It is formed of an upper half 4m located on the rear side and a lower half 4n located on the rear side. The front clamping piece 4k is fixed (welded) to the front piece 4d with the upper edge of the upper half 4m in contact with the front half 4i of the lower piece, so that the horizontal stepped portion 4l is fixed to the lower piece. It is set to have a gap S between it and the front half 4i, and to be located at approximately the same height as the rear half 4j (in this embodiment, slightly lower than the rear half 4j). At the same time, the lower half portion 4n is provided at a position below the vertical step portion 4h and in front of the vertical step portion 4h.

Further, the upper end surface portion 12e provided on the stile main body portion 12a of the upper horizontal stile material 12 is disposed in such a manner that the lateral step-shaped portion 4l is spaced upward, that is, spaced apart upwardly by a distance greater than the gap S. However, a horizontal plate-like lower piece 17a of the L-shaped support member 17 is attached to the upper edge 12e via a bolt 17b. The support member 17 is configured such that a rising piece (upper piece) 17c that rises up in the form of a vertical plate (above) comes into contact with the lower half 4n of the front clamping piece 4k from the rear side. 17c is set to be positioned (deviated) to the front side of the vertical step portion 4h, with the upper end edge 17d being located at approximately the same height as the horizontal step portion 4l. With this configuration, the support member 17 moves upward on the front side of the vertically stepped portion 4h with the rising piece portion 17c sliding vertically relative to the lower half portion 4n of the front side clamping piece, so that the upper end The edge 17d is movable so as to closely oppose the front half 4i of the lower piece.

On the other hand, a horizontal plate-shaped upper piece 18a of the rear side clamping piece 18 having an inverted L shape is fixed to the rear half 4j of the lower side piece through a bolt 18b. The vertical plate-shaped lower piece 18c is in contact with the rising piece 17c of the support member 17 so as to be slidable in the vertical direction. The support member 17 is allowed to move upward while being held between the lower half 4n and the lower piece 18c of the rear side holding piece 18. In the state including the allowance, the upper side frame member 12 is configured to be able to move upwardly within the range of the gap S until the upper side frame member main body portion 12e abuts the lower edge of the lower half portion 4n of the front clamping piece. There is. 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 stile frame X with a four-periphery frame and a sleeve plate 16 will be incorporated into the opening, but in this case, the lower horizontal stile material 13 is The lower rail material 5a provided in 5 is supported and fixed and its displacement in the vertical direction is regulated, and the door end side vertical frame material is supported and fixed to the door end side vertical frame material 7 and its displacement in the left and right direction is regulated. As a result, the sleeve portion 3 is firmly attached and fixed so that it will not easily fall off from the opening in the event of a fire, while the upper horizontal frame member 12 is provided with a gap S in the vertical direction with respect to the upper horizontal frame member 4. Because the vertical stile material 14 on the door end side is not fixed to the frame due to the heat generated by the fire, the upper horizontal stile material 12 undergoes upward displacement due to thermal expansion. is allowed by the gap S, and the vertical stile material 12 itself is set not to be supported by the frame, so displacement toward the door end is allowed, and as a result, In the event of a fire, the sleeve portion 3 can be firmly supported and fixed to the frame and can tolerate displacement due to thermal expansion, thereby maintaining high fire prevention performance.

Furthermore, in this case, the rising piece 17c rising upward from the support member 17 provided on the upper side frame member 12 is held by the front and rear clamping pieces 4k, 18 provided on the upper side frame member 4. Since support is provided in the front and rear direction in a clamped state that allows upward displacement, the upper side stile members 12 can be reliably supported not only in normal times but also in the event of a fire. This prevents the section 3 from becoming unstable.

Furthermore, the lower horizontal stile material 13 is supported and fixed to the frame side by fixing it to the lower rail material 5a provided on the floor surface F side via screws 13e, and the lower side vertical stile material 15 is fixed to the frame side. Since the support and fixation to the side is done by fixing to the door end side vertical frame member 7 via the screws 15d, the support and fixation of these lower side frame members 13 and door end side vertical frame member 15 to the frame side is possible. By fixing with screws, the sleeve portion 3 can be firmly attached to the body frame side, and the attachment work can be facilitated.
