Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the above prior art, in the event of a fire on one side of the space partitioned by the shutter device, if the shutter curtain is fully closed, the flames and smoke from the fire can be blocked to some extent from spreading to the other side space. However, even when the shutter curtain is fully closed, there is a possibility that the heat on one side of the space partitioned by the shutter curtain is transmitted through the guide rail and the soleplate to the floor material on the lower side of the other side space. In such a case, there is a risk that this floor material may be thermally deteriorated or burned.

Means for Solving the Problems

[0005] In view of such problems, one aspect of the present invention has the following configuration. An installation structure of an opening / closing device that comes into contact with a wooden floor and assumes a closed state, characterized in that a fire-resistant member is provided between an opening / closing device component member installed on the wooden floor and the wooden floor.

Advantages of the Invention

[0006] Since the present invention is configured as described above, it can prevent heat from a fire or the like from being transmitted to the wooden floor.

Best Mode for Carrying Out the Invention

[0008] Next, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009] The opening / closing device 1 is a shutter device installed in a wooden housing X and constitutes a relatively large heavy shutter device. This opening / closing device 1 includes an opening / closing body 10 that closes in a manner of partitioning a space, left and right guide rails 20, 20 that guide the opening / closing body 10 in the closing and opening directions, a storage unit 30 that extends the opening / closing body 10 in the closing direction and stores it in the opening direction, and a doorstop 40 that abuts against the opening / closing body 10 when fully closed. This opening / closing device 1 applies an opening / closing device installation structure A in a structure in which opening / closing device components such as the guide rails 20 and the doorstop 40 are installed on the lower wooden floor x2.

[0010] The opening / closing body 10 is formed by connecting a plurality of slats formed by bending a horizontally long substantially rectangular metal plate so as to rotate between the upper and lower sides. This opening / closing body 10 may be referred to as a slat shutter curtain. As another example of this opening / closing body 10, there may be a mode made of a flexible sheet such as fire resistance, a mode made of a plurality of panels, a mode in which a plurality of pipes are arranged at intervals in the vertical direction, a mode in which slats, flexible sheets, panels, pipes, etc. are appropriately combined, and the like.

[0011] The guide rail 20 is a long member that is continuous in the vertical direction at each of both end sides in the width direction of the opening / closing body 10. This guide rail 20 is arranged on both sides of an opening that is opened and closed by the opening / closing body 10 so as to guide the width direction end portion of the opening / closing body 10 in the opening / closing direction. This guide rail 20 is formed of a hard metal material (for example, steel, stainless steel, aluminum, an alloy containing these, etc.).

[0012] The storage part 30 includes a winding shaft 31 for winding and unwinding the opening / closing body 10, shaft support brackets 32, 32 for supporting the winding shaft 31 at both ends thereof, a winding shaft case 33 for covering the periphery of the winding shaft 31 and the opening / closing body 10 wound around the winding shaft 31, an opening / closing machine 34 which is a drive source for driving the winding shaft 31 to rotate, and a suspension reinforcement part 35 for receiving and suspending the shaft support brackets 32, 32 and the winding shaft case 33 from below and reinforcing them (see FIGS. 1 and 2). This storage part 30 is fixed to the surface of the wooden wall x1 via the support frame 3 on the rear side.

[0013] The winding shaft 31 is configured in a long cylindrical shape extending in the width direction of the opening / closing body and is rotatably supported. This winding shaft 31 may be configured in a manner such that a winding body is rotatably supported on the outer periphery of a non-rotatable fixed shaft via a bearing, or a shaft part integrated with the winding body is rotatably supported by the shaft support bracket 32 via a bearing, etc.

[0014] Two shaft support brackets 32 are provided at intervals in the lateral width direction so as to be located on both sides of the winding shaft 31. These two shaft support brackets 32, 32 are respectively connected to the support frame 3 on the rear side by fixing with a fixing tool (for example, a screw, a bolt, a rivet, etc.) not shown, or by welding.

[0015] The suspension reinforcement part 35 is configured by connecting a plurality of long rigid members (for example, various steel materials such as angle steel, channel steel, C-shaped steel, etc.). The lower end side of this suspension reinforcement part 35 receives the winding shaft case 33 and the shaft support brackets 32, 32 from below via a receiving member 35a extending in the lateral width direction. Also, the upper end side of the suspension reinforcement part 35 is connected to the support frame 3 on the rear side of the storage part 30.

[0016] A cover part 26 is provided below the suspension reinforcement part 35 so as to surround the opening / closing path of the opening / closing body 10 at the height position of the ceiling part 2. This cover part 26 is fixed to a non-movable part near the ceiling part 2 (for example, the receiving member 35a or other non-movable members on the ceiling side).

[0017] The support frame 3 is configured by connecting a plurality of steel materials in a substantially rectangular frame shape along the rear surface of the storage part 30. This support frame 3 is fixed to the surface of the wooden wall x1 to reinforce the surface. To this support frame 3, as described above, the pivot brackets 32, 32 of the storage part 30, the upper rear end part of the suspension reinforcement part 35, etc. are fixed. As another example other than the illustrated example, it is also possible to omit the support frame 3 and directly fix the storage part 30 to the wooden wall x1.

[0018] The tatami folding part 40 is embedded in the wooden floor x2 so as to face the end part in the closing direction (downward in the illustrated example) of the opening / closing body 10 (see FIG. 8). This tatami folding part 40 is continuous in the lateral width direction between the left and right guide rails 20, 20 so as to be abutted by the opening / closing body 10 when it is fully closed. The tatami folding part 40 in the illustrated example is formed by processing a plate-like member made of metal (for example, stainless steel, iron, aluminum, alloys thereof, etc.) into an inverted concave shape in the longitudinal section.

[0019] The wooden structure X to which the opening / closing device 1 is to be installed is a large building mainly made of wood. This wooden structure X integrally constitutes a wooden wall x1 located on the rear side of the opening / closing device 1, a wooden floor x2 located on the lower side of the opening / closing device 1, etc.

[0020] The wooden wall x1 includes a wooden base x11 and a plate-like fire-resistant wall material x12 that covers the outer surface of this wooden wall x1 in a multi-layered manner, and is integrally configured.

[0021] According to the illustrated example, the wooden base x11 is a wooden column or a wooden structural plywood, and is continuous in a long shape extending in the vertical direction. The upper end side and the lower end side of this wooden base x11 are connected to other woods etc. that constitute the wooden structure X. The fire-resistant wall material x12 is a plate-like fire-resistant member having heat insulation properties (for example, gypsum board, calcium silicate board, etc.).

[0022] The wooden floor x2 is integrally configured by overlapping a plurality of plate materials including wooden plate materials. Specifically, as shown in FIG. 8, this wooden floor x2 includes a first wooden board x21 exposed on the outermost layer side, a multi-layered (two layers in the illustrated example) fire-resistant board x22, x23 overlapping the lower side of the first wooden board x21, and a second wooden board x24 overlapping the lower side of these fire-resistant boards x22, x23.

[0023] The first wooden board x21 is a single-layer or multi-layer wooden flat member. For example, a wooden flooring material or other decorative boards may be used for this first wooden board x21.

[0024] The fire-resistant boards x22, x23 are plate-shaped fire-resistant members having heat insulation properties (for example, gypsum boards, calcium silicate boards, etc.). The same materials as the fire-resistant wall materials x12 of the wooden wall x1 can be used for these fire-resistant boards x22, x23.

[0025] The second wooden board x24 is a single-layer or multi-layer wooden flat member. For example, a wooden structural plywood or a panel board can be used for this second wooden board x24.

[0026] The opening / closing device installation structure A is configured by providing first to third fire-resistant members 51, 52, 53, which will be described later, between the wooden floor x2 having the above configuration and the opening / closing device constituent members (guide rails 20, sliding doors 40, etc. in the illustrated example) on this wooden floor x2.

[0027] Hereinafter, the specific structure of this opening / closing device installation structure A will be described in detail. The wooden floor x2 is provided with a first recess x2a containing the guide rail 20, the first fire-resistant member 51, and the second fire-resistant member 52, and a second recess x2b containing the sliding door 40 and the third fire-resistant member 53.

[0028] The inner surface of the first recess x2a is formed by a notch x211 of the first wooden board x21 and a notch x221 of the fire-resistant board x22. Also, the bottom surface of the first recess x2a is formed by the upper surface x231 of the fire-resistant board x23 (see FIGS. 7 and 9, etc.).

[0029] Inside this first concave portion x2a, a guide rail 20 is erected. And a first refractory member 51 is provided between the inner surfaces (notches x211, x221) of the first concave portion x2a and the outer surface of the guide rail 20. Also, a second refractory member 52 is provided between the lower ends of the guide rail 20 and the first refractory member 51 and the bottom surface (the upper surface x231 of the refractory plate material x23) of the first concave portion x2a (see FIG. 9).

[0030] The second concave portion x2b is formed by a notch x212 that vertically penetrates the first wooden plate material x21 and the upper surface x222 of the refractory plate material x22 located below this notch x212 (see FIGS. 7 and 11). This second concave portion x2b and the first concave portion x2a communicate horizontally in the portion of the first wooden plate material x21. That is, the notch x211 and the notch x212 in the first wooden plate material x21 communicate with each other (see FIG. 7).

[0031] In the second concave portion x2b, a sliding door 40 is embedded so that both side surfaces are covered by a third refractory member 53 (see FIG. 8). Specifically, the sliding door 40 is placed on the upper surface x222 of the refractory plate material x22 within the second concave portion x2b. One side surface and the other side surface in the opening and closing body thickness direction of this sliding door 40 are covered by a third refractory member 53. The third refractory member 53 fits between each side surface of the sliding door 40 and the inner surface (notch x212) of the second concave portion x2b.

[0032] The first refractory member 51 is a strip-shaped member made of a refractory member having heat insulation properties (for example, a gypsum board, a calcium silicate board, etc.), and covers the outer surface on the lower end side of the guide rail 20. According to FIG. 5, this first refractory member 51 is integrally formed, but it may also be formed by combining a plurality of flat plate-like members.

[0033] The second fire-resistant member 52 is a sheet-like member having fire resistance and flexibility, and is composed of, for example, silica cloth, glass cloth, or the like. This second fire-resistant member 52 is provided on the wooden floor x2 so as to cover the guide rail 20 and the lower end portion of the first fire-resistant member 51. According to the illustrated example, this second fire-resistant member 52 is a single sheet, but may be used in a plurality of sheets stacked as needed to appropriately adjust the position of the guide rail 20 in the height direction.

[0034] The third fire-resistant member 53 covers one side surface and the other side surface in the opening / closing body thickness direction in the tatami folding 40 over substantially the entire length in the lateral width direction. According to the illustrated example, it is formed in a long shape with a rectangular longitudinal section continuous in the lateral width direction. For this third fire-resistant member 53, for example, a member having good fire resistance and low thermal conductivity such as a gypsum board, a calcium silicate board, or a ceramic may be used.

[0035] <Manufacturing method of the opening / closing device installation structure> Next, the manufacturing method of the opening / closing device installation structure A will be described in detail with reference to FIGS. 3 to 8. First, a notch x221 is processed in the fire-resistant plate material x22 before the first wooden plate material x21 is stacked (see FIG. 3). Note that the procedure for processing this notch x221 may be either before or after the fire-resistant plate material x22 is stacked on the fire-resistant plate material x23.

[0036] Then, the flexible second fire-resistant member 52 is laid so as to cover the notch x221 and the recess formed by the bottom surface thereof (the upper surface x231 of the fire-resistant plate material x22).

[0037] Next, as shown in FIGS. 4 to 5, the guide rail 20 is erected on the upper surface of the laid second fire-resistant member 52. The lower end portion of the guide rail 20 is covered by the second fire-resistant member 52, is erected substantially vertically, and is connected and fixed to the wooden wall x1, the tatami portion 26, or the like.

[0038] Next, as shown in FIGS. 5 to 6, a strip-shaped first fire-resistant member 51 is inserted between the outer surface of the guide rail 20 and the notch x221.

[0039] Next, as shown in FIGS. 6 to 7, the shoe-fold 40 and the third fire-resistant members 53, 53 are placed on the upper surface of the fire-resistant plate material x22.

[0040] Next, as shown in FIGS. 7 to 8, the first wooden plate material x21 is superposed on the upper surface of the fire-resistant plate material x22. At this time, the guide rail 20, the first fire-resistant member 51, the shoe-fold 40, the third fire-resistant members 53, etc. penetrate through the notches x211, x212 of the first wooden plate material x21 and are exposed to the outside. Further, the sheet-shaped second fire-resistant member 52 is covered by the first wooden plate material x21.

[0041] <Function and effect> Therefore, according to the opening / closing device installation structure A having the above configuration and its manufacturing method, it is possible to prevent heat from a fire or the like from being transmitted to the wooden floor x2 through the opening / closing device constituent members (the guide rail 20 and the shoe-fold 40 in the illustrated example).

[0042] Specifically, even when heat from a fire or the like is transferred to the guide rail 20, the first fire-resistant member 51 can block the heat from being transmitted to the first wooden plate material x21. Further, the second fire-resistant member 52 can block the heat from being transmitted to the second wooden plate material x24.

[0043] Also, even when heat from a fire or the like is transferred to the shoe-fold 40, the third fire-resistant member 53 can block the heat from being transmitted to the first wooden plate material x21.

[0044] Ultimately, it is possible to prevent the wooden portion of the wooden floor x2 from being thermally deteriorated or burned due to heat from a fire or the like.

[0045] <Modification example> According to the above embodiment, as a particularly preferred example, the first fire-resistant member 51, the second fire-resistant member 52, and the third fire-resistant member 53 are provided. However, as another example, among these three types of fire-resistant members, it is also possible to omit any one or two of them.

[0046] According to the above embodiment, as a particularly preferred example, the guide rail 20 and the first fire-resistant member 51 are inserted into the upper and lower notches x211 and x221 of the first wooden board x21 and the fire-resistant board x22 and abutted against the second fire-resistant member 52 on the fire-resistant board x23. However, as another example, the guide rail 20 is inserted into the upper and lower notches x211 and x221, the first fire-resistant member 51 is inserted only into the upper notch x211 and abutted against the second fire-resistant member 52 on the fire-resistant board x22, or the lower notch x221 is omitted, and the guide rail 20 and the first fire-resistant member 51 are inserted only into the notch x221 of the first wooden board x21 and abutted against the second fire-resistant member 52 on the fire-resistant board x22. Furthermore, as another example, it is also possible to omit the upper and lower notches x211 and x221, lay the second fire-resistant member 52 on the first wooden board x21, and make the guide rail 20 and the first fire-resistant member 51 abut against the second fire-resistant member 52 on the first wooden board x21 and stand upright.
