[0009] (First embodiment) Hereinafter, an embodiment of the present invention will be described. Fig. 1 is a schematic front view showing an opening / closing device according to the present invention, and Fig. 2 is a schematic side view showing an example of an arrangement of a storage section in the opening / closing device.

[0010] In this specification, the "width direction of the opening / closing body" refers to a direction that is approximately perpendicular to the opening / closing direction of the opening / closing body, and is not the thickness direction of the opening / closing body (the left-right direction in Figure 1), and is sometimes referred to as the "left-right direction." Furthermore, the "thickness direction of the opening / closing body" refers to the thickness direction of the opening / closing body, and is sometimes referred to as the "front-rear direction."

[0011] (Overall configuration of the switchgear) First, the overall configuration of the opening and closing device according to the present invention will be described. As shown in Fig. 1, the opening and closing device 1 is installed on a wooden base X that forms the skeleton of a building, and includes an opening and closing body 10 that opens and closes an opening in the building, a storage section 20 that extends the opening and closing body 10 in the closing direction and stores it in the opening direction, and a guide rail 30 that guides the opening and closing body 10 in the closing and opening directions.

[0012] [Opening and closing body] The opening / closing body 10 is configured by connecting a plurality of slats 10a, each made by bending a horizontally elongated, generally rectangular metal plate, so that the slats 10a can rotate vertically. Other examples of the opening / closing body 10 include a flexible sheet, a plurality of panels, a plurality of pipes arranged at intervals vertically, and an appropriate combination of slats, flexible sheets, panels, pipes, etc.

[0013] [Storage section] 2, the storage section 20 is configured to include a winding shaft 21 that winds and unwinds the opening-closing body 10, a support bracket 22 that supports the winding shaft 21 at both ends, an opening / closing machine 23 that is a drive source that drives and rotates the winding shaft 21, a hanging reinforcement section 24 that supports the support bracket 22 etc., and a winding shaft case 25 that covers the winding shaft 21 etc. This storage section 20 is placed in a space 50a defined by a storage section side fireproof structure 50 described later.

[0014] The winding shaft 21 is formed in a long cylindrical shape spanning the width direction of the opening / closing body and is rotatably supported. The winding shaft 21 is configured in such a manner that the winding body is rotatably supported on the outer periphery of a non-rotatable fixed shaft via a bearing, or in such a manner that a shaft portion integral with the winding body is rotatably supported on a support bracket 22 via a bearing.

[0015] The left and right support brackets 22 each include, for example, a flat support body 22a, upper and lower flange portions (not shown) bent outward in the left-right direction from the upper and lower edge portions of the support body 22a, and an attachment portion 22b bent inward in the left-right direction from the rear edge portion of the support body 22a, and are integrally formed, for example, by bending a flat metal plate or by welding the various portions together. The support bracket 22 supports the winding shaft 21 at both ends thereof, and is fastened to a wooden base X (XA) that forms the building skeleton by fasteners M1 that are inserted into mounting portions 22b of the support bracket 22. The wooden base XA is made up of wooden members that constitute the building frame, such as pillars, intermediate pillars, beams, and lower walls.

[0016] The opening / closing device 23 is composed of an electric motor, gears, etc. The opening / closing device 23 is supported by a support bracket 22 on one side (the right side in FIG. 1), and transmits its rotational force to the winding shaft 21 by a power transmission means 23a such as a chain and a sprocket. In the opening and closing device 1, the winding shaft 21 is driven forward and reverse by the operation of the opening and closing machine 23, and the opening and closing body 10 rises and falls while being guided at both left and right ends by guide rails 30 erected on the left and right sides of the opening of the building, thereby opening and closing the opening.

[0017] The suspension reinforcement part 24 is formed by assembling a plurality of long steel members such as angle irons, and includes a support member 24a that supports the left and right support brackets 22 and the winding shaft case 25 from below, a lower piece 24b that is connected to approximately the center of the support member 24a in the left-right direction and extends forward (to the right in Figure 2), a rising piece 24c that is connected to the lower piece 24b and extends upward, and an attachment part 24d that is connected to the upper end of the rising piece 24c, and is fastened to the wooden base X (XB) via the attachment part 24d by a fastener M2. The wooden base XB is made up of wooden members that form the skeleton of a building, such as beams.

[0018] The winding shaft case 25 is configured to cover the periphery of the winding shaft 21 and the opening-closing body 10 wound around the winding shaft 21. The winding shaft case 25 is formed in an elongated shape, for example, with a substantially U-shaped or arc-shaped vertical cross section that continues in the opening / closing width direction, and is attached to the hanging reinforcement part 24 so as to cover the periphery of the winding shaft 21 and the opening-closing body 10 wound around the winding shaft 21.

[0019] [Guide rail] 1, the guide rails 30 are long members that are continuous vertically on both widthwise ends of the opening-closing body 10. The guide rails 30 are fixed to the wooden base X of the building skeleton so as to guide the widthwise ends of the opening-closing body 10 in the opening and closing direction.

[0020] (Storage unit layout (installation structure)) Next, a specific description will be given of the arrangement (installation structure) of the storage section 20 in the opening and closing device 1. Fig. 3 is a perspective conceptual diagram showing an example of the arrangement of the storage section in the opening and closing device according to the present invention, and conceptually shows the arrangement of the storage section 20, the storage section-side fireproof structure 50, the front compartment F (indoor space, etc.), and the rear compartment R (indoor space, etc.).

[0021] 3, the storage section 20 is surrounded by a storage section-side fireproof structural body 50 made up of a plurality of fireproof wall materials 51 to 55. The storage section-side fireproof structural body 50 is located between the front section F and the rear section R, and above the ceiling Fa of the front section F and the ceiling Ra of the rear section R.

[0022] 2, the storage unit 20 is disposed in a space 50a defined by a storage unit-side fireproof structural body 50 disposed above the ceiling member 26, and is attached and fixed to a wooden base X of the building skeleton. In other words, the storage unit 20 is disposed surrounded by the storage unit-side fireproof structural body 50 made up of a plurality of fireproof wall materials 51 to 55, and is attached and fixed to the wooden base X of the building skeleton by fasteners M1 and M2.

[0023] <Fire-resistant structure on storage section side> As shown in Figure 3, the storage section side fireproof structure 50 is composed of multiple fireproof wall materials 51 to 55, namely, a fireproof front wall material 51, a fireproof rear wall material 52, left and right fireproof side wall materials 53, 54, and a fireproof upper wall material 55, and is formed in a roughly box-like shape that is open downward.

[0024] The front fire-resistant wall material 51 and the rear fire-resistant wall material 52 are arranged in an upright position, extending vertically and spaced apart in the thickness direction of the opening / closing body (the left-right direction in FIG. 2). The left and right fire-resistant side wall materials 53, 54 are arranged in an upright position extending vertically and spaced apart in the width direction of the opening / closing body (left and right direction in Figure 1) so as to be connected to each side end of the fire-resistant front wall material 51 and the fire-resistant rear wall material 52, respectively. The upper fire-resistant wall material 55 is arranged horizontally so as to straddle and connect to the upper ends of the front fire-resistant wall material 51, the rear fire-resistant wall material 52 and the left and right fire-resistant side wall materials 53, 54. The storage section side fireproof structural body 50 is configured as a continuous fireproof wall surface that is surrounded on the top surface and on all four side surfaces by arranging the fireproof wall materials 51 to 55 in this manner.

[0025] These fire-resistant wall materials 51 to 55 are made of, for example, plate-shaped fire-resistant materials (such as gypsum boards, calcium silicate boards, glass wool materials, or combinations of these) that have fire resistance, heat resistance, heat insulation, etc., and are provided on the surface of the wooden base X of the building frame in single (single layer structure) or multiple (multi-layer structure: two sheets in the illustrated example) layers.

[0026] [Fireproof front wall material] 2, the fire-resistant front wall material 51 is disposed so as to cover the front part of the storage section 20 from the front, with a predetermined distance (work space) between it and the front part of the storage section 20. This fire-resistant front wall material 51 constitutes the front wall material of the storage section side fire-resistant structural body 50 formed in a substantially box shape, and is immovably fixed by fasteners (screws, bolts, etc.) not shown, adhesive, etc., while abutting against the front surface of the wooden base X (XC) made of wooden beams or the like. In the illustrated example, the fire-resistant front wall material 51 is provided in a two-layer structure consisting of an outer fire-resistant wall material 51a that is placed in contact with the wooden base of the building structure, and an inner fire-resistant wall material 51b that is placed to cover the outer fire-resistant wall material 51a from the inside, but it may also be configured as a single layer (single-layer structure) or a multi-layer structure of three or more layers.

[0027] [Fireproof rear wall material] 2, the fire-resistant rear wall material 52 is disposed on the rear side of the storage section 20 so as to cover the rear of the storage section 20 from behind. The fire-resistant rear wall material 52 is disposed between the wooden base X (XA) and the storage section 20, and constitutes the rear wall material of the storage section-side fire-resistant structure 50, which is formed in a substantially box shape.

[0028] The fire-resistant rear wall material 52 is disposed between the wooden base XA and the storage section 20, thereby covering the front surface of the wooden base XA. That is, as shown in FIG. 2, the fire-resistant rear wall material 52 is disposed extending in the vertical direction from the ceiling member 26 to the fire-resistant upper wall material 55, thereby covering the front surface of the wooden base XA.

[0029] As shown in Figure 2, this fire-resistant rear wall material 52 is abutted against the front surface of the wooden base XA and is fastened and immovably fixed to the wooden base XA by a fastener M1 inserted into the mounting portion 22b of the support bracket 22.

[0030] Specifically, the mounting portion 22b of the pivot bracket 22 has a generally rectangular (approximately oblong) shape when viewed from the front, and is formed with a plurality of insertion holes (not shown) for inserting fasteners M1 in the vertical direction, and fasteners M1 such as screws or bolts are inserted into these insertion holes, penetrate the rear fire-resistant wall material 52, and are screwed into and engaged with the wooden base XA, thereby attaching and fixing the pivot bracket 22. The threaded portion at the tip of the fastener M1 is screwed into the wooden base XA, and its head is engaged with the surface of the mounting portion 22b.

[0031] In the illustrated example, the fire-resistant rear wall material 52 is composed of upper and lower first fire-resistant rear wall materials 52a1, 52a2 (outer fire-resistant wall materials) that are arranged in contact with the wooden base XA, and a second fire-resistant rear wall material 52b (inner fire-resistant wall material) that is arranged to cover the upper and lower first fire-resistant rear wall materials 52a1, 52a2. In this case, a joint (seam) C is formed between the lower surface of the upper first fire-resistant rear wall material 52a1 and the upper surface of the lower first fire-resistant rear wall material 52a2, and this joint C is configured to be covered by the second fire-resistant rear wall material 52b.

[0032] Therefore, by disposing this second fire-resistant rear wall material 52b, it is possible to prevent the lower first fire-resistant rear wall material 52a2 from bending forward and widening the joint C due to, for example, the storage section 20 being attached to the lower first fire-resistant rear wall material 52a2 side, and it is also possible to prevent flames and hot air from leaking from the joint C to the wooden base XA side.

[0033] Furthermore, a reinforcing sealant made of glass fiber or the like may be applied to the joint C, or a putty may be applied to cover the joint C. By configuring it in this way, it is possible to more effectively prevent flames and hot air from leaking from the joint C to the wooden base XA side.

[0034] In the illustrated example, the first fire-resistant rear wall materials 52a1, 52a2 are configured as upper and lower sections, with the upper first fire-resistant rear wall material 52a1 and the lower first fire-resistant rear wall material 52a2, but they may be configured as a single first fire-resistant rear wall material without being divided into upper and lower sections. Also, the fire-resistant rear wall material 52 has a two-layer structure consisting of the first fire-resistant rear wall materials 52a1, 52a2 (outer fire-resistant wall material) and the second fire-resistant rear wall material 52b (inner fire-resistant wall material), but is not limited to this example and may be configured as a single layer (single-layer structure) or a multi-layer structure of three or more layers.

[0035] [Fireproof side wall material] 3, the left and right fire-resistant side wall materials 53, 54 are arranged to cover the left and right ends of the storage section 20 from the sides, with a predetermined interval (work space) between them in the width direction of the opening / closing body of the storage section 20. The left and right fire-resistant side wall materials 53, 54 are fastened to a wooden base (not shown) of the building skeleton, and constitute the left and right wall materials of the storage section-side fire-resistant structural body 50, which is formed in a substantially box shape.

[0036] [Fire-resistant upper wall material] 2, the fire-resistant upper wall material 55 is disposed so as to cover the upper part of the storage section 20 from above, with a predetermined distance (work space) between it and the upper part of the storage section 20. This fire-resistant upper wall material 55 constitutes the upper wall material of the storage section side fire-resistant structural body 50 formed in a substantially box shape, and is fastened to the wooden base XB.

[0037] This fire-resistant upper wall material 55 is fastened and immovably fixed to the wooden base XB by fasteners M2 inserted into the mounting portions 24d of the hanging reinforcement portions 24 while in contact with the underside of the wooden base XB.

[0038] Specifically, the mounting portion 24d of the hanging reinforcement portion 24 is an angled member having an L-shaped cross section extending in the thickness direction of the opening / closing body (left-right direction in FIG. 2), and one side portion is fixed (for example, by welding) to the rising piece 24c. The other side portion has a plurality of insertion holes (not shown) for inserting fasteners M2, and fasteners M2, such as screws or bolts, are inserted into these insertion holes, penetrate the upper fire-resistant wall material 55, and are screwed into the wooden base XB to attach and secure the hanging reinforcement portion 24. The threaded portion of the fastener M2 at its tip end is screwed into the wooden base XB, and its head is engaged with the surface of the other side portion of the mounting portion 24d.

[0039] In the illustrated example, the fire-resistant upper wall material 55 is provided in a two-layer structure consisting of an outer fire-resistant wall material 55a that is placed in contact with the wooden base of the building structure, and an inner fire-resistant wall material 55b that is placed so as to cover the outer fire-resistant wall material 55a from the inside, but it may also be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0040] [Ceiling material] The opening of the storage-compartment-side fireproof structure 50 is closed by the ceiling member 26. The ceiling member 26 can be made of, for example, gypsum board, rock wool board, decorative plywood, fiberboard, or a metal plate such as aluminum or stainless steel, and one end of the ceiling member 26 is placed and fixed on, for example, a flange 27a formed in a substantially L-shape in side view that protrudes substantially horizontally from the lower end of the lintel 27 of the opening and closing device 1.

[0041] The ceiling member 26 is provided with an inspection hatch 26a that can be opened, closed, or removed, and is configured to allow inspection, replacement, and other maintenance work to be performed on the storage section 20 (e.g., the opening / closing mechanism 23, etc.) located within the space 50a defined by the storage section side fireproof structure 50.

[0042] In this way, the storage section 20 is placed in the space 50a defined by the storage section side fireproof structure 50 arranged above the ceiling member 26, so even if flames or hot air reach the storage section 20 side in the event of a fire, the flames or hot air can be prevented from leaking out to the wooden base X side of the building structure.

[0043] Furthermore, the storage section side fireproof structure 50 is configured as a structure of a predetermined shape, approximately box-like, that opens downward from each of the fireproof wall materials, namely the fireproof front wall material 51, the fireproof rear wall material 52, the left and right fireproof side wall materials 53, 54, and the fireproof upper wall material 55, so that fireproof design can be easily performed.

[0044] Furthermore, the storage section 20 of the opening / closing device 1 is arranged in a space 50a defined by the storage section side fireproof structure 50, and this space 50a also functions as a work space where the installation, inspection and other maintenance work of the storage section 20 can be performed, thereby improving the ease of installation, inspection and maintenance of the opening / closing device 1.

[0045] (Guide rail arrangement (installation structure)) Next, the arrangement (installation structure) of the guide rail 30 in the opening and closing device 1 will be specifically described. Fig. 4 is a perspective conceptual diagram showing an example of the arrangement of the guide rail in the opening and closing device according to the present invention, and conceptually shows the arrangement of the guide rail 30, the guide rail-side fireproof structure 60, the front compartment F (indoor space, etc.), and the rear compartment R (indoor space, etc.). Fig. 5 is a cross-sectional schematic diagram showing an example of the arrangement of the guide rail in the opening and closing device, and Fig. 6 is a cross-sectional view of the guide rail.

[0046] The guide rail 30 is surrounded by a guide rail side fireproof structural body 60 made up of a plurality of fireproof wall materials 61 to 65. The guide rail side fireproof structural body 60 is disposed between the side wall Fb of the front compartment F and the side wall Rb of the rear compartment R.

[0047] 5, the guide rail 30 is disposed in a space 60a defined by a guide rail-side fire-resistant structural body 60 made up of a plurality of fire-resistant wall materials 61-65, and is attached and fixed to a wooden base X of the building skeleton. In other words, the guide rail 30 is disposed surrounded by the guide rail-side fire-resistant structural body 60 made up of a plurality of fire-resistant wall materials 61-65, and is attached and fixed to the wooden base X of the building skeleton by fasteners M3.

[0048] <Guide rail side fireproof structure> 5, the guide rail-side fireproof structure 60 is made up of a plurality of fireproof wall materials 61 to 65, specifically, it has a first fireproof wall material 61, a second fireproof wall material 62, a third fireproof wall material 63, a fourth fireproof wall material 64, and a fifth fireproof wall material 65, which are plate-shaped and arranged upright in the vertical direction, and these fireproof wall materials 61 to 65 are configured to define a recessed space 60a that is recessed in a roughly U-shape in plan view. The guide rail 30 is installed so as to be housed in the space 60a defined by the guide rail-side fireproof structure 60.

[0049] Each of these fire-resistant wall materials 61 to 65 is made of, for example, a plate-shaped fire-resistant material (such as gypsum board, calcium silicate board, glass wool material, or a combination of these) that has fire resistance, heat resistance, insulation properties, etc., and is provided on the surface of the wooden base X of the building structure in a single layer (single-layer structure) or in multiple layers (multi-layer structure: two sheets in the illustrated example) stacked on top of each other.

[0050] The wooden base X of the building skeleton has first and second support columns XD and XE extending vertically and spaced a predetermined distance apart in the thickness direction (front-to-back direction) of the opening / closing body, and a plurality of intermediate columns XF extending vertically and spaced between the first and second support columns XD and XE. The first and second support columns XD and XE are formed to have approximately the same cross-sectional dimensions and cross-sectional shape, and the plurality of intermediate columns XF are formed to have a cross-sectional shape whose dimension in the width direction of the opening / closing body (left-to-right direction in Figure 5) is smaller than that of the first and second support columns XD and XE. Each of the fire-resistant wall materials 61 to 65 covers the first and second support columns XD, XE and the plurality of intermediate columns XF, and is arranged to define a space 60a that is recessed in a roughly U-shape when viewed from above so that the guide rail 30 can be stored therein.

[0051] [First fireproof wall material] The first fire-resistant wall material 61 is arranged to cover the indoor-facing surface of the first support XD. Specifically, as shown in Fig. 5, the first fire-resistant wall material 61 is immovably fixed in contact with the indoor-facing side surface of the first support XD using fasteners (screws, bolts, etc.) or adhesive (not shown). The end of this first fire-resistant wall material 61 on the guide rail 30 side is arranged to be connected to the end of a fourth fire-resistant wall material 64, which is arranged to cover the side surface of the first support XD facing the guide rail 30. In the illustrated example, the first fire-resistant wall material 61 is provided in a two-layer structure shown as 61a and 61b in the drawing, but it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0052] [Second fireproof wall material] The second fire-resistant wall material 62 is disposed so as to cover the indoor-facing surface of the second support XE. Specifically, the second fire-resistant wall material 62 is immovably fixed in contact with the side surface of the second support XE facing the indoor side by fasteners (screws, bolts, etc.) (not shown) or adhesive. The end of this second fire-resistant wall material 62 on the guide rail 30 side is disposed so as to be connected to the end of a fifth fire-resistant wall material 65 disposed so as to cover the side surface of the second support XE facing the guide rail 30 side. In the illustrated example, the second fire-resistant wall material 62 is provided in a two-layer structure shown as 62a and 62b in the drawing, but it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0053] [Third fireproof wall material] The third fire-resistant wall material 63 is arranged to cover the interior-side surface of each intermediate column XF. As shown in Fig. 5, each intermediate column XF includes, for example, a first intermediate column XF1 arranged on the first support column XD side, a second intermediate column XF2 arranged on the second support column XE side, and a third intermediate column XF3 arranged between the first intermediate column XF1 and the second intermediate column XF2 and closer to the first intermediate column XF1. Each of these intermediate columns XF is formed to have approximately the same dimension in the opening / closing body width direction (left-right direction in Fig. 5), and these dimensions are formed to be smaller than the dimensions of the first support column XD and the second support column XE in the opening / closing body width direction.

[0054] The third fire-resistant wall material 63 is fixed immovably in contact with the side surface of each intermediate column XF facing the interior of the room. Specifically, the third fire-resistant wall material 63 is fixed immovably to the first intermediate column XF1 and the second intermediate column XF2 by fasteners (screws, bolts, etc.) or adhesive (not shown), and is fixed immovably to the third intermediate column XF3 by fasteners M3 that attach and fix the guide rail 30 to the third intermediate column XF3.

[0055] In addition, one end of the third fire-resistant wall material 63 is arranged so as to be connected to the outer surface of the fourth fire-resistant wall material 64 attached to the first support XD, and the other end of the third fire-resistant wall material 63 is arranged so as to be connected to the outer surface of the fifth fire-resistant wall material 65 attached to the second support XE.

[0056] Therefore, the indoor-side wall surface of the third fire-resistant wall material 63 is recessed from the wall surfaces of the first fire-resistant wall material 61 and the second fire-resistant wall material 62, and by being connected to the fourth fire-resistant wall material 64 and the fifth fire-resistant wall material 65, a continuous recessed outer surface is formed toward the indoor side. The guide rail 30 is disposed in the space formed by this recessed outer surface, that is, the space 60 a defined by the guide rail side fire-resistant structure 60 .

[0057] In the illustrated example, the third fire-resistant wall material 63 is provided in a two-layer structure shown as 63a and 63b in the drawing, but it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0058] [Fourth fireproof wall material] The fourth fire-resistant wall material 64 is fixed immovably in place by fasteners (screws, bolts, etc.) or adhesives (not shown) in contact with the side of the first support XD facing the guide rail 30 so as to cover the side. In the illustrated example, the fourth fire-resistant wall material 64 is provided in a two-layer structure shown as 64a and 64b in the drawing, but it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0059] [No. 5 fireproof wall material] In addition, the fifth fire-resistant wall material 65 is fixed immovably by fasteners (screws, bolts, etc.) or adhesives, etc., not shown, in contact with the side of the second support XE facing the guide rail 30 so as to cover the side. In the illustrated example, the fifth fire-resistant wall material 65 is provided in a two-layer structure shown as 65a and 65b in the drawing, but it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0060] [Inner panel material] The opening facing the interior of the guide rail side fireproof structure 60 is closed by an inner panel material 66 as a panel material, with a part of the rail body 31 of the guide rail 30 (the opening portion into which the widthwise end of the opening / closing body 10 is inserted) exposed. This inner panel material 66 is arranged to ensure design and fire resistance, and can be made of, for example, gypsum board, rock wool board, decorative plywood, fiberboard, etc., and is fixed to the first fireproof wall material 61 and the second fireproof wall material 62 with fasteners or adhesives (not shown).

[0061] The guide rail 30 is placed in a space 60a defined by the guide rail side fireproof structure 60, and is covered with an inner panel material 66 except for a portion of the rail body 31, thereby improving the appearance and design of the interior. Furthermore, when inspecting or maintaining the guide rail 30, the space 60a (work space) defined by the guide rail side fire-resistant structure 60 can be exposed simply by removing the inner panel material 66, making it easy to inspect or maintain the guide rail 30 without damaging the guide rail side fire-resistant structure 60.

[0062] [No. 6 fire-resistant wall material, outer panel material] The outdoor surface of the wooden base X (XD, XE, XF) is covered with a sixth fire-resistant wall material 67 and an outer panel material 68. The sixth fire-resistant wall material 67 is fixedly secured to the outdoor surface of each wooden base X (XD, XE, XF) by fasteners or adhesives (not shown), and the outer panel material 68 is fixedly secured to the sixth fire-resistant wall material 67 by fasteners or adhesives (not shown). Although the sixth fire-resistant wall material 67 is provided in a two-layer structure shown as 67a and 67b in the drawing, it may be configured as a single layer (single layer structure) or a multi-layer structure of three or more layers.

[0063] <Guide rail mounting structure> Next, we will explain in detail the arrangement (installation structure) of the guide rail 30. As shown in Fig. 6, the guide rail 30 includes a rail body 31 that guides the opening / closing body 10 in the up and down direction, and a mounting bracket 32 ​​for mounting and fixing this rail body 31 to the third intermediate column XF3. The rail body 31 is mounted and fixed to the third intermediate column XF3 of the building skeleton via this mounting bracket 32.

[0064] The rail body 31 is formed from a metal material such as steel, stainless steel, or aluminum alloy, and has a guide portion 31a for guiding the widthwise end portion of the opening / closing body 10 in the vertical direction, and a support portion 31b for supporting the guide portion 31a, as shown in Fig. 6. The rail body 31 is continuous in an elongated shape in the vertical direction.

[0065] The guide portion 31a has a U-shaped portion 31a1 whose cross-sectional shape is formed in an approximately U-shape that opens in the width direction of the opening / closing body (left and right direction in Figure 6), and a crank-shaped portion 31a2 which is formed in an approximately crank shape and connected to each open end of this U-shaped portion 31a1. The U-shaped portion 31a1 is provided so that the opening portion into which the widthwise end of the opening / closing body 10 is inserted is exposed to the outside of the inner panel material 66, and serves as a guide portion that guides the opening / closing body 10 in the closing and opening directions. The crank-shaped portion 31a2 serves as a receiving portion that receives the side edge of the inner panel material 66.

[0066] The support portion 31b has a generally U-shaped cross section that opens in the width direction of the opening / closing body, and a portion of the opening side is joined (for example, welded) to a side portion of the crank-shaped portion 31a2 of the guide portion 31a to form an integrated unit. One piece of the mounting bracket 32 ​​is fastened to this support portion 31b.

[0067] The mounting bracket 32 ​​is made of a metal material such as steel, stainless steel, or aluminum alloy, and is an angle-shaped member with an L-shaped cross section that is continuous in the vertical direction, with one end fastened to the support part 31b of the rail main body 31 by a fastener m such as a screw or bolt, and the other end fastened to the third intermediate column XF3 by a fastener M3 such as a screw. The threaded portion on the tip side of the fastener M3 penetrates the mounting bracket 32 ​​and the third fire-resistant wall material 63 and is screwed into the third intermediate column XF3, and its head engages with the surface of the other end of the mounting bracket 32.

[0068] Furthermore, a sealant S is filled in the gap between the rail main body 31 and the inner panel material 66. Specifically, when the guide rail is installed, a small gap may occur between the crank-shaped portion 31a2 of the rail main body 31 and the end of the inner panel material 66, and this gap is filled with the sealant S, which is made of an amorphous paste-like (putty-like) sealing material such as a silicon-based, modified silicon-based, or polysulfide-based material. This sealant S is filled in the gap in a fluid state and hardens at room temperature to become an elastic body.

[0069] As described above, the guide rail 30 is attached and fixed to the wooden base X (XD, XE, XF) of the building skeleton, and is disposed in the space 60a defined by the guide rail-side fireproof structural body 60. Therefore, even if flames or hot air reach the guide rail 30 side in the event of a fire, the flames or hot air can be prevented from leaking out to the wooden base X side of the building skeleton.

[0070] Furthermore, the guide rail side fireproof structure 60 is configured as a structure of a predetermined shape in which a space 60a that is recessed in an approximately U-shape when viewed from above is defined by each of the first fireproof wall material 61, the second fireproof wall material 62, the third fireproof wall material 63, the fourth fireproof wall material 64 and the fifth fireproof wall material 65, making it easy to carry out fireproof design.

[0071] Furthermore, the guide rail 30 of the opening and closing device 1 is arranged in a space 60a defined by the guide rail side fireproof structure 60, and this space 60a also functions as a work space where the guide rail 30 can be installed, inspected, and other maintenance work can be performed, thereby improving the ease of installation, inspection, maintenance, etc. of the opening and closing device 1.

[0072] Next, other examples of the arrangement of the guide rail according to the present invention will be described. In the following alternative examples 1 to 3, the guide rail 30 shown in Figures 5 and 6 is replaced with other guide rails 70, 80, and 90, so the explanation will be focused on the changed parts, and the same components will be assigned the same reference numerals and redundant explanations will be omitted.

The U-shaped portion 71a1 is provided so that the opening portion into which the widthwise end of the opening / closing body 10 is inserted is exposed to the outside of the inner panel material 66, and serves as a guide portion that guides the opening / closing body 10 in the closing and opening directions. The L-shaped portion 71a2 serves as a cover portion that covers the side edge of the inner panel material 66 from the outside.

[0076] The support portion 71b has a generally U-shaped cross section that opens in the thickness direction of the opening / closing body (the vertical direction in FIG. 8), and both ends on the opening side are joined (for example, welded) to the side portions of the U-shaped portion 71a1 of the guide portion 71a to form an integrated unit. One piece of the mounting bracket 72 is fastened to this support portion 71b.

[0077] The mounting bracket 72 is made of a metal material such as steel, stainless steel, or aluminum alloy, and is an angle-shaped member with an L-shaped cross section that continues in the vertical direction, with one end fastened to the support part 71b of the rail main body 71 by a fastener m such as a screw or bolt, and the other end fastened to the third intermediate column XF3 by a fastener M3 such as a screw.

[0078] In this alternative example 1, the guide rail 70 is also disposed in the space 60a defined by the guide rail side fireproof structural body 60, and therefore the same effects as those of the mounting structure of the guide rail 30 described above can be achieved.

[0079] (Another example 2) FIG. 9 is a schematic cross-sectional view showing another example of the arrangement of the guide rail in the opening and closing device according to the present invention, and FIG. 10 is a cross-sectional view of the same guide rail.

[0080] The rail body 81 is formed from a metal material such as steel, stainless steel, or aluminum alloy, and has a guide portion 81a for guiding the widthwise end portion of the opening / closing body 10 in the vertical direction, and a support portion 81b for supporting the guide portion 81a, as shown in Fig. 10. The rail body 81 is continuous in an elongated shape in the vertical direction.

[0081] The guide portion 81a has a U-shaped portion 81a1 whose cross-sectional shape is formed in an approximately U-shape that opens in the width direction of the opening / closing body (left and right direction in Figure 10), and a flat plate-shaped portion 81a2 provided on both sides of the opening end side of this U-shaped portion 81a1. The guide portion 81a is provided by exposing a part (the end portion forming the opening portion) of a flat plate-like portion 81a2 provided on both sides of the opening end side of the U-shaped portion 81a1 to the outside of the inner panel material 66, and forms a guide portion that guides the opening / closing body 10 in the closing direction and the opening direction. The flat plate-like portion 81a2 is provided so as to abut against the end portion of the inner panel material 66.

[0082] The support portion 81b has a generally U-shaped cross section that opens in the width direction of the opening / closing body, and both ends on the opening side are joined (for example, welded) to the sides of the U-shaped portion 81a1 of the guide portion 81a so as to embrace the U-shaped portion 81a1 and form an integral unit. One piece of the mounting bracket 82 is fastened to this support portion 81b.

[0083] The mounting bracket 82 is made of a metal material such as steel, stainless steel, or aluminum alloy, and is an angle-shaped member with an L-shaped cross section that is continuous in the vertical direction, with one end fastened to the support part 81b of the rail main body 81 by a fastener m such as a screw or bolt, and the other end fastened to the third intermediate column XF3 by a fastener M3 such as a screw. The threaded portion at the tip of the fastener M3 passes through the mounting bracket 82 and the third fire-resistant wall material 63 and is screwed into the third intermediate column XF3, with its head engaging with the surface of the mounting bracket 82.

[0084] In this alternative example 2, the guide rail 70 is also disposed in the space 60a defined by the guide rail side fireproof structural body 60, and therefore the same effects as those of the mounting structure of the guide rail 30 described above can be achieved.

[0085] (Another example 3) FIG. 11 is a schematic cross-sectional view showing another example of the arrangement of the guide rail in the opening and closing device according to the present invention, and FIG. 12 is a cross-sectional view of the same guide rail. The guide rail 90 comprises a rail body 91 that guides the opening / closing body 10 in the vertical direction, and a mounting bracket 92 for mounting and fixing this rail body 91 to the third intermediate column XF3, and the rail body 91 is mounted and fixed to the third intermediate column XF3 of the building frame via this mounting bracket 92.

[0086] The rail body 91 is made of a metal material such as steel, stainless steel, or aluminum alloy, and has a guide portion 91a for guiding the widthwise end portion of the opening / closing body 10 in the vertical direction, and a support portion 91b for supporting the guide portion 91a, as shown in Fig. 12.

The guide portion 91a is provided by exposing a part (the end portion forming the opening portion) of a flat plate-like portion 91a2 provided on both sides of the opening end side of the U-shaped portion 91a1 to the outside of the inner panel material 66, and forms a guide portion that guides the opening-closing body 10 in the closing direction and the opening direction. The flat plate-like portion 91a2 is provided so as to abut against the end portion of the inner panel material 66.

[0088] The support portion 91b is an L-shaped portion having a substantially L-shaped cross section, and is integrally formed by being connected to one end of the U-shaped portion 91a1 of the guide portion 91a. One piece of the mounting bracket 92 is fastened to the support portion 91b.

The threaded portion at the tip of the fastener M3 penetrates the mounting bracket 92 and the third fire-resistant wall material 63 and is screwed into the third intermediate column XF3, with its head engaging with the surface of the mounting bracket 92.

[0090] In this alternative example 3, the guide rail 70 is also disposed in the space 60a defined by the guide rail side fireproof structural body 60, and therefore the same effects as those of the mounting structure of the guide rail 30 described above can be achieved.

[0091] (Second embodiment) As described above, in the first embodiment, the storage section side fireproof structure 50 and the guide rail side fireproof structure 60 are configured as independent structures, but the present invention is not limited to this example. Below, an example in which the storage section side fireproof structure 50 and the guide rail side fireproof structure 60 are configured as an integrated structure will be described. Fig. 13 is a perspective conceptual diagram showing another example of an arrangement mode of the opening and closing device according to the present invention, and conceptually shows an arrangement mode of the opening and closing device 1, the fireproof structure 100, the front compartment F (indoor space, etc.), and the rear compartment R (indoor space, etc.).

[0092] As shown in Fig. 13, the opening and closing device 1 of the second embodiment is surrounded by a fireproof structure 100 made up of a plurality of fireproof wall materials. This fireproof structure 100 is disposed between the front compartment F and the rear compartment R, and is configured to connect the storage section side fireproof structure 50 shown in Fig. 3 and the guide rail side fireproof structure 60 shown in Fig. 4.

[0093] The fire-resistant structure 100 has left and right fire-resistant side wall materials 110 arranged in an upright position extending vertically and spaced apart in the width direction of the opening / closing body, and a fire-resistant upper wall material 120 arranged horizontally so as to straddle and connect to the upper ends of these left and right fire-resistant side wall materials 110, and is configured so that these left and right fire-resistant side wall materials 110 and fire-resistant upper wall material 120 form a continuous fire-resistant wall surface that is roughly gate-shaped when viewed from the front, with the left and right side surfaces and top surface surrounded.

[0094] Specifically, the left and right fire-resistant side wall materials 110 are configured in the same manner as the guide rail side fire-resistant structure 60 shown in Figure 5, and the fire-resistant upper wall material 120 is configured in the same manner as the fire-resistant upper wall material 55 of the storage section side fire-resistant structure 50 shown in Figure 2, and is configured so that the guide rail side fire-resistant structure 60 is connected to the fire-resistant upper wall material 55. Therefore, the storage section 20 and guide rail 30 of the opening and closing device 1 are arranged so that the upper side of the storage section 20 and the sides of the storage section 20 and guide rail 30 are surrounded by a fire-resistant structure 100 that is formed in a roughly gate-like shape when viewed from the front.

[0095] The fire-resistant structure 100 also has a fire-resistant front wall material 130 that is arranged at a predetermined distance from the front of the storage section 20 so as to cover the front of the storage section 20 from the front, and a fire-resistant rear wall material 140 that is arranged on the rear side of the storage section 20 so as to cover the rear of the storage section 20 from the rear.

[0096] Specifically, the fire-resistant front wall material 130 is configured in the same manner as the fire-resistant front wall material 51 shown in Figure 2, and is arranged in an upright position extending vertically so as to connect to the front end of the fire-resistant upper wall material 120 and the upper front end of the left and right fire-resistant side wall materials 110. In addition, the fire-resistant rear wall material 140 is configured in the same manner as the fire-resistant rear wall material 52 shown in Figure 2, and is arranged in an upright position extending vertically so as to connect to the rear end of the fire-resistant upper wall material 120 and the upper rear end of the left and right fire-resistant side wall materials 110. Therefore, the storage section 20 of the opening and closing device 1 is disposed with its front and rear sides surrounded by the front fire-resistant wall material 130 and the rear fire-resistant wall material 140.

[0097] Furthermore, as in the first embodiment described above, the storage section 20 and the guide rail 30 are attached and fixed to the wooden base X of the building structure by the fastening devices M1 to M3, and a plate-shaped ceiling member (not shown) is provided below the storage section 20 so as to cover the lower part of the storage section 20 from below.

[0098] As described above, the opening and closing device 1 having the storage section 20 and the guide rail 30 is arranged in a space defined by the fire-resistant structure 100 and is attached and fixed to the wooden base X of the building skeleton, so that even if flames or hot air reach the storage section 20 or the guide rail 30 in the event of a fire, the flames or hot air can be prevented from leaking out to the wooden base X of the building skeleton.

[0099] Furthermore, since the fire-resistant structure 100 is configured as a structure of a predetermined shape that surrounds the opening and closing device 1, fire-resistant design can be easily performed, and the ease of installation, inspection, and other maintenance work of the opening and closing device 1 can be improved.
