[0003] [Patent Document 1] JP 2016-211257 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in recent years, there are cases where a large building framework is constructed from wood and a large shutter device such as a heavy-duty shutter is installed on the wooden framework. In such cases, the relatively heavy guide rails are fastened to the wooden structure by fasteners such as screws and bolts. However, in the unlikely event of a fire, heat from the fire will be transferred to the fasteners, causing thermal deterioration of the fastening portions of the fasteners in the wooden structure, which may result in the fasteners becoming loose or falling off. [Means for solving the problem]

[0005] In view of the above problems, one aspect of the present invention has the following configuration. An installation structure for an opening / closing device that fixes an opening / closing device that opens and closes an opening to a wooden structure provided to the side of the opening, the installation structure comprising: a fastener having a shaft portion that can be inserted into the wooden structure and a head portion provided at the rear end of the shaft portion; and a fire-resistant insulating material having fire resistance and thermal insulation properties, wherein the fastener fixes the opening / closing device to the wooden structure by inserting the shaft portion into an attachment portion that is a part of the opening / closing device and into the wooden structure, and the fire-resistant insulating material is interposed between the attachment portion and the head, and is arranged on the surface of the attachment portion so as to surround the periphery of the head of the fastener. Effect of the Invention

[0006] Since the present invention is configured as described above, even in the unlikely event of a fire occurring, the transfer of heat due to the fire to the fastener can be reduced. [Brief description of the drawings]

[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic front view of a switchgear to which the installation structure of the switchgear according to the present invention is applied, Fig. 2 is a schematic vertical cross-sectional view taken along line (II)-(II) in Fig. 1, and Fig. 3 is a schematic cross-sectional view taken along line (III)-(III) in Fig. 1, showing an example of the installation structure of the switchgear according to the present invention. In this specification, the term "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. In addition, the "inner side in the width direction of the opening / closing body" refers to the direction toward the inside of the opening / closing body along the width direction of the opening / closing body. For example, when the guide rail 40A on the right side in FIG. 1 is used as a reference, the inner side in the width direction of the opening / closing body is the left side.

[0009] (First embodiment) The opening / closing device 1 includes an opening / closing body 10 that performs a closing operation to partition a space, a storage section 20 that extends the opening / closing body 10 in the closing direction and stores it in the opening direction, and a guide rail 40A that guides the opening / closing body 10 in the closing direction and the opening direction.

[0010] The wooden structure X is a large-scale building made mainly of wood. The wooden structure X includes a wooden base x1 and a fire-resistant member x2 that covers the wooden base x1 (see Figs. 2 and 3).

[0011] The wooden base x1 is a wooden building material that constitutes the basic framework of the wooden structure X, such as rectangular prism-shaped wooden pieces that constitute pillars and beams, or flat structural plywood that constitutes the walls. The wooden base x1 in the illustrated example is erected from the floor surface below the opening and closing device 1 to the ceiling part 2 above the opening and closing device 1.

[0012] The fire-resistant member x2 is a plate-shaped building material having fire resistance and heat insulation properties (e.g., gypsum board, calcium silicate board, etc.), and is arranged to cover the front side of the wooden base x1 and the inner side in the width direction of the opening / closing body (the left side side in Figure 3). In the illustrated example, a single fire-resistant member x2 is provided on each surface of the wooden base x1 to form a single layer structure, but it is also possible to provide multiple layers of each member to form a multi-layer structure.

[0013] The opening / closing body 10 is made up of a plurality of slats connected together so as to be able to rotate between the top and bottom, and is sometimes called a slat shutter curtain. The slats are made by bending a horizontally elongated, generally rectangular metal plate. Other examples of this opening / closing body 10 include a structure made of a flexible sheet, a structure made of multiple panels, a structure in which multiple pipes are arranged at intervals above and below, and a structure made of an appropriate combination of slats, flexible sheets, panels, pipes, etc.

[0014] The storage section 20 is equipped with a winding shaft 21 that winds up and unwinds the opening-closing body 10, pivot brackets 22, 22 that support the winding shaft 21 at both ends, a winding shaft case 23 that covers the winding shaft 21 and the opening-closing body 10 wound around the winding shaft 21, an opening / closing machine 24 which is a driving source that drives and rotates the winding shaft 21, and a support base frame 25 that supports the pivot brackets 22, 22, etc. (see Figures 1 and 2).

[0015] The winding shaft 21 is formed in a long cylindrical shape extending in the width direction of the opening / closing body, and is supported so as to be freely rotatable. This winding shaft 21 may be configured in such a manner that the winding body is rotatably supported via a bearing on the outer periphery of a non-rotatable fixed shaft, or in such a manner that a shaft portion integral with the winding body is rotatably supported via a bearing on a support bracket 22.

[0016] The winding shaft case 23 is formed in an elongated shape with a generally U-shaped or arc-shaped cross section continuing in the opening / closing width direction. The winding shaft case 23 is attached to the support base frame 25 so as to cover the winding shaft 21 and the opening / closing body 10 wound around the winding shaft 21 from the front side (the left side in FIG. 2).

[0017] The opening / closing device 24 is composed of an electric motor, gears, etc. The opening / closing device 24 is supported by a support bracket 22 on one side (the right side according to FIG. 1), and transmits its rotational force to the winding shaft 21 by a chain, a sprocket, etc. (not shown).

[0018] The support base frame 25 is constructed integrally by connecting a plurality of long hard members (for example, various steel materials such as angle iron and channel iron) to have a long connecting portion 25a that connects the left and right pivot brackets 22, 22 at their lower ends, and a support portion 25b that supports a substantially central portion in the width direction of the connecting portion 25a and is fastened to the rear wooden structure X. Note that, although Fig. 1 shows an example in which one support portion 25b is arranged in the width direction of the connecting portion 25a, the number of support portions 25b to be arranged may be multiple.

[0019] The left and right pivot brackets 22, 22 and the support portion 25b are immovably fixed to the wooden structure X by fasteners (not shown) (for example, screws, bolts, anchor members, etc.).

[0020] The guide rails 40A are long members that are continuous vertically on both ends of the opening / closing body 10 in the width direction. The guide rail 40A is fixed to the visible surface Xa of the wooden structure X so as to guide the widthwise end of the opening / closing body 10 in the opening / closing direction.

[0021] As shown in FIG. 3, the guide rail 40A is integrally provided with a rail body 41 protruding forward from the visible surface Xa of the wooden structure X, and a base member 42 for fastening the rail body 41 to the visible surface Xa of the wooden structure X. The rail body 41 and the base member 42 are each formed from a hard metal material (for example, steel, stainless steel, aluminum alloy, etc.).

[0022] The base member 42 has a generally concave cross section that extends in a long strip in the vertical direction and has a plate-shaped portion 42a that contacts the visible surface Xa of the wooden structure X and protruding pieces 42b, 42b that protrude perpendicularly (forward) from both left and right end portions of the plate-shaped portion 42a. The base member 42 is fastened and fixed to the mounting surface Xa of the wooden structure X by fasteners M1.

[0023] The rail main body 41 integrally includes a guide portion 41a having a guide recess 41a1 that surrounds the widthwise end of the opening / closing body 10 in a concave cross section and guides it in the vertical direction, and a support portion 41b that protrudes forward from the visible surface Xa of the wooden structure X and supports the guide portion 41a. In this rail body 41, the rear end of the guide portion 41a and the rear end of the support portion 41b are overlapped with both protruding pieces 42b, 42b of the previously attached base member 42. The overlapping portions are integrally joined by fasteners M2 (e.g., screws, bolts, rivets, etc.) that are inserted through the rail body 41. In the guide rail 40A, a closed space a1 (air layer) is formed by the guide portion 41a, the support portion 41b, and the base member 42 (see FIG. 3).

[0024] The lower end of the guide rail 40A is fixed to a fixed portion on the lower side (for example, the floor surface, the lower frame, the door sill, etc.) via a bracket (not shown), and the upper end is fixed to a fixed portion on the upper side (for example, the ceiling 2, the steel material on the upper side, the beam material, etc.) via a bracket (not shown).

[0025] As another example of the guide rail 40A, it is possible to use a configuration in which the guide rail 40A is configured in a hollow column shape by using a plurality of members other than those shown in the drawings, or a configuration in which the guide rail 40A is configured in an integrated hollow tube shape.

[0026] (Guide rail installation structure) Next, a specific installation structure of the guide rail 40A will be described. FIG. 4 is an explanatory diagram in which an example of an installation structure for a switching device according to the present invention is disassembled into its constituent parts. Specifically, an installation structure for installing a guide rail 40A on a wooden structure X is shown.

[0027] [Fastening device] The fastener M1 is a screw member (for example, a screw or a bolt) having a shaft portion with a threaded portion m11 at the tip end and a head portion m12 at the rear end, and a plurality of fasteners M1 are provided at intervals in the vertical direction. The screw portion m11 (shaft portion) of each fastener M1 penetrates the pressing member 70, the fireproof heat insulating material 60, the receiving seat 50, and the base member 42, and also penetrates the fireproof member x2 to be screwed into the wooden base x1.

[0028] [Receiving seat] The receiving seat 50 has a rising portion 51 extending approximately perpendicular to the plate-shaped portion 42a of the base member 42 that constitutes the guide rail 40A, a contact portion 53 extending along the plate-shaped portion of the base member 42, and an inclined portion 52 connected to one end edge of the rising portion 51 and one end edge of the contact portion 53, and is formed, for example, by bending a flat rectangular metal plate.

[0029] A screw hole 52a for inserting the screw portion m11 of the fastener M1 is formed in approximately the center of the inclined portion 52, and the peripheral portion surrounding this screw hole 52a is configured to receive the head m12 of the fastener M1. Since this screw hole 52a is formed to penetrate approximately perpendicularly to the surface of the inclined portion 52, the screw portion m11 of the fastener M1 is inserted along this screw hole 52a, and as a result, the fastener M1 is driven obliquely into the visible surface Xa of the wooden structure X. Therefore, the guide rail 40A can be firmly fixed to the wooden structure X (strongly fixed against external forces).

[0030] In addition, the inclination angle of the inclined portion 52 relative to the abutment portion 53 (the inclination angle relative to the sight plane xa) can be set to any angle at which the guide rail 40A can be firmly fixed to the wooden structure X (strongly fixed against external forces), and is not particularly limited. For example, by setting it to 10 to 30 degrees, workability can be improved when installing the guide rail 40A (for example, when screwing in the fastener M1). The receiving seat 50 may also be made of a non-metallic material such as silicone or plastic having fire resistance and heat insulation properties.

[0031] [Fireproof insulation material] A fireproof insulation material 60 having fire resistance and heat insulation properties, for example, a fiber sheet such as silica cloth or glass cloth, or a ceramic such as a silica-based, silicon carbide-based, or alumina-based material, is disposed on the surface (upper surface) of the inclined portion 52 of the receiving seat 50. This fireproof insulation material 60 is interposed between the receiving seat 50 and the head m12 of the fastener M1, and is disposed so as to surround the periphery of the head m12 of the fastener M1 on the surface (upper surface) of the inclined portion 52, thereby reducing the transfer of heat to the fastener M1 via the receiving seat 50 in the event of a fire.

[0032] The fireproof insulation material 60 is interposed between the receiving seat 50 and the head m12 of the fastener M1, and can be formed into any shape (size, thickness) that can surround the head m12 of the fastener M1 on the surface (upper surface) of the inclined portion 52. For example, it can be formed into an approximately circular or approximately rectangular shape having an insertion hole 60a in the center through which the screw portion m11 (shaft portion) of the fastener M1 is inserted.

[0033] In the illustrated example, a single layer of fireproof insulation material 60 is provided on the inclined portion 52 of the receiving seat 50, but it is also possible to provide multiple layers to form a multi-layer structure. By providing such a multi-layer structure, the heat insulating property of the fireproof insulation material 60 can be further improved (heat blocking performance can be further improved).

[0034] Also, the fireproof insulation material 60 may be configured to have an adhesive material on at least one surface. In this case, during construction, the fireproof insulation material 60 can be temporarily attached by sticking it to the inclined portion 52 of the support seat 50 via the adhesive material.

[0035] [Holding member] The pressing member 70 is a member that presses down from above the fireproof thermal insulation material 60 placed on the receiving seat 50 to fix it in place. The pressing member 70 is configured to have substantially the same shape (size) as the fireproof thermal insulation material 60 or is smaller than the fireproof thermal insulation material 60, and is formed, for example, in a substantially circular or rectangular shape having an insertion hole 70a in the center through which the screw portion m11 (shaft portion) of the fastener M1 is inserted. When the screw portion m11 of the fastener M1 is screwed into the wooden structure X, the fireproof insulating material 60 is stably fixed onto the receiving seat 50 by the pressing member 70.

[0036] The material of the pressing member 70 is not particularly limited, but it is preferable that the pressing member 70 be made of a non-metallic material such as a silicon material, a synthetic resin material, or a ceramic material, which has fire resistance and heat insulation properties.

[0037] (Guide rail installation procedure) Next, an example of a procedure for installing the guide rail 40A will be described with reference to FIGS.

[0038] <Base component placement> 5(a), the base member 42 of the guide rail 40A is placed on the visible surface Xa of the wooden skeleton X. In this case, the back surface of the plate-shaped portion 42a of the base member 42 is placed in contact with a predetermined mounting position of the visible surface Xa of the fire-resistant member x2.

[0039] <Placement of receiving seat> 5(b), the receiving seat 50 is placed at a predetermined position on the base member 42. In this case, the receiving seat 50 can be easily positioned by abutting the outer surface of the rising portion 51 of the receiving seat 50 against the inner surface of the protruding piece portion 42b of the base member 42. In this state, the inclined portion 52 of the receiving seat 50 is inclined with respect to the plate-shaped portion 42a of the base member 42. In addition, an adhesive such as double-sided tape may be provided on the outer surfaces of the rising portion 51 and the contact portion 53 of the receiving seat 50 so that the receiving seat 50 can be temporarily attached to the base member 42. Also, the receiving seat 50 may be configured in advance to be joined to a predetermined position on the base member 42 prior to construction.

[0040] <Arrangement of fireproof insulation material> 6(a), the fireproof insulating material 60 is placed on the surface (upper surface) of the inclined portion 52 of the receiving seat 50. In this case, the fireproof insulating material 60 is placed so that the screw hole 52a of the inclined portion 52 and the insertion hole 60a of the fireproof insulating material 60 communicate with each other. An adhesive such as double-sided tape may be provided on the surface of the fireproof insulation material 60 facing the receiving seat 50 so that the fireproof insulation material 60 can be temporarily attached to the inclined portion 52. The fireproof insulation material 60 may be previously attached to a predetermined position of the receiving seat 50.

[0041] <Fixing the base material> 6(b), the fastener M1 is screwed in with the pressing member 70 placed on the upper surface of the fireproof thermal insulation material 60. In this case, the screw hole 52a formed in the inclined portion 52 of the receiving base 50 is formed to penetrate the inclined portion 52 substantially perpendicularly to the surface of the inclined portion 52, so that the screw portion m11 of the fastener M1 is inserted along the screw hole 52a. As a result, the fastener M1 is obliquely driven into the visible surface Xa of the wooden structure X, and the screw portion m11 of the fastener M1 penetrates the fire-resistant member x2 and screws into the wooden base x1, thereby firmly fastening the base member 42 to the wooden structure X.

[0042] <Installation of the rail body> Next, as shown in Fig. 7, the rail body 41 is attached to the base member 42 fastened to the visible surface Xa of the wooden structure X. In this case, the rear end of the guide portion 41a and the rear end of the support portion 41b are overlapped with both protruding pieces 42b, 42b of the base member 42, and are integrally joined by fasteners M2 (e.g., screws, bolts, rivets, etc.). As a result, the guide rail 40A has a closed space a1 (air layer) defined by the guide portion 41a, the support portion 41b, and the base member 42 (see Fig. 3).

[0043] According to the above configuration, the fireproof and heat-insulating material 60 having fire resistance and heat insulation properties is disposed on the surface (upper surface) of the inclined portion 52 of the receiving seat 50, and this fireproof and heat-insulating material 60 is interposed between the receiving seat 50 and the head m12, and is disposed so as to surround the periphery of the head m12 of the fastener M1 on the surface (upper surface) of the inclined portion 52, thereby reducing the transfer of heat during a fire to the fastener M1 via the receiving seat 50. As a result, it is possible to prevent the wooden base x1 from being thermally deteriorated around the screw portion m11 of the fastener M1, and further to prevent the fastener M1 from falling off or the guide rail 40A from coming off due to the fastener M1 falling off.

[0044] In addition, in this embodiment, the head m12 and a part of the shaft of the fastener M1 are located within the closed space a1 (air layer) of the guide rail 40A. Therefore, in the event of heat being received from the outside due to a fire, this space a1 (air layer) can prevent the heat from being transmitted to the fastener M1.

[0045] Second embodiment Next, another embodiment of the opening and closing device installation structure according to the present invention will be described. Fig. 8 is a cross-sectional schematic diagram along the line (IV)-(IV) in Fig. 1, which shows another example of the opening and closing device installation structure according to the present invention. Fig. 9 is an explanatory diagram in which the same installation structure (another example) is disassembled into its constituent parts. Specifically, Figs. 8 and 9 show an installation structure in which the pivot bracket 22 of the opening and closing device 1 is installed on a wooden skeleton X.

[0046] The pivot bracket 22 is formed in a substantially L-shape in plan view and includes a flat support body 22a that rotatably supports the winding shaft 21, and an attachment piece 22b that is connected substantially perpendicularly from the rear edge of the support body 22a toward the inside in the left-right direction. The pivot bracket 22 is formed integrally, for example, by bending a metal flat plate material or by welding each portion.

[0047] The mounting piece 22b of the pivot bracket 22 contacts the visible surface Xa of the wooden structure X, and the pivot bracket 22 is fastened to the visible surface Xa of the wooden structure X by a fastener M1 inserted into this mounting piece 22b, and the mounting piece 22b and the head m12 of the fastener M1 are fixed together with a fireproof insulation material 60' and a pressing member 70' interposed between the mounting piece 22b and the head m12 of the fastener M1. The configurations of the fireproof insulation 60' and the clamping member 70' are similar to those of the fireproof insulation 60 and the clamping member 70 described above, respectively, and therefore the parts having similar functions and structures are given the same symbols and duplicate detailed explanations are omitted.

[0048] When attaching the pivot bracket 22 to the wooden structure X, the mounting piece 22b of the pivot bracket 22 is abutted against a predetermined mounting position on the front surface Xa, and the fireproof insulating material 60' is placed on the surface (front surface) of the mounting piece 22b. In this case, the mounting piece 22b is arranged so that the screw hole 22b1 of the mounting piece 22b and the insertion hole 60a of the fireproof insulating material 60' communicate with each other. An adhesive such as double-sided tape may be provided on the surface of the fireproof thermal insulation material 60' facing the mounting piece 22b so that the fireproof thermal insulation material 60' can be temporarily attached to the mounting piece 22b. Also, the fireproof thermal insulation material 60' may be configured to be joined to the mounting piece 22b in advance.

[0049] Next, with the pressing member 70' placed on the upper surface of the fireproof thermal insulation material 60', the fastener M1 is screwed in. As a result, the threaded portion m11 of the fastener M1 penetrates the fireproof member x2 and screws into the wooden base x1, thereby fastening the pivot bracket 22 to the wooden skeleton X.

[0050] According to the above configuration, a fireproof and heat-insulating material 60' having fire resistance and heat insulation properties is disposed on the surface (front surface) of the mounting piece 22b of the pivot bracket 22, and this fireproof and heat-insulating material 60' is interposed between the mounting piece 22b and the head m12, and is disposed so as to surround the periphery of the head m12 of the fastener M1 on the surface (front surface) of the mounting piece 22b, thereby reducing the transfer of heat during a fire to the fastener M1 via the mounting piece 22b of the pivot bracket 22. As a result, it is possible to prevent the wooden base x1 from being thermally deteriorated around the screw portion m11 of the fastener M1, and further to prevent the fastener M1 from falling off or the guide rail 40A from coming off due to the fastener M1 falling off.

[0051] (Modification) In the above-mentioned embodiment, the surface of the head m12 of the fastener M1 (for example, only the top surface of the head, or the top surface of the head and the peripheral surface) may be configured to be covered with a fire-resistant coating material having fire resistance and heat insulation. As the fire-resistant coating material, for example, a known expandable fire-resistant paint or a sheet-shaped fire-resistant coating material containing ammonium polyphosphate, a carbonizing agent, and a foaming agent can be used. In this case, due to the temperature rise during a fire, the ammonium polyphosphate decomposes and bonds with the carbonizing agent, and a carbonized heat-insulating layer is formed on the surface of the head m12 by the gas generated from the foaming agent. Therefore, the transfer of heat to the fastener M1 in the event of a fire can be further reduced.

[0052] In the above-mentioned embodiment, when the fireproof heat insulating material 60, 60' is made of a flexible fiber sheet such as silica cloth or glass cloth, the insertion hole 60a formed in the center of the fiber sheet may be formed as a through hole smaller than the thread diameter (maximum outer diameter of the male thread) of the screw part m11 of the fastener M1, and a plurality of cuts (slits) extending radially may be formed around the periphery of the insertion hole 60a. In this case, when the screw part m11 of the fastener M1 is screwed in, the peripheral part of the insertion hole 60a of the fiber sheet is inserted in a bent state into the screw hole 52a of the receiving seat 50 (first embodiment) and the screw hole 22b1 of the pivot bracket 22 (second embodiment). Therefore, a portion of the fiber sheet (fireproof insulating material) is interposed between the inner surface of each screw hole 52a, 22b1 and the shaft portion of the fastener M1 located within this inner surface, thereby further reducing the transfer of heat to the fastener M1 in the event of a fire.

[0053] In the first embodiment described above, the base member 42 of the guide rail 40A may be attached to the wooden structure X without using the receiving seat 50. In this case, similar to the second embodiment described above, the fireproof insulating material 60 and the pressing member 70 may be interposed between the plate-shaped portion 42a of the base member 42 and the head m12 of the fastener M1 to fix them.

[0054] The present invention is not limited to the above-mentioned specific configuration, and can be modified as appropriate without departing from the gist of the present invention.
