DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

[0009] 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 term "outer side in the width direction of the opening / closing body" refers to the direction toward the outside of the opening / closing body along the width direction of the opening / closing body. For example, when the guide rail on the right side is used as a reference, the outer side in the width direction of the opening / closing body is the right side. In addition, the term "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 on the right side is used as a reference, the inner side in the width direction of the opening / closing body is the left side. <First embodiment> FIG. 1 shows an opening and closing device to which an example of a guide rail installation structure according to the present invention is applied. The opening and closing device 1 includes an opening and closing body 10 that performs a closing operation to partition a space, a storage section 20 that extends the opening and closing body 10 in a closing direction and stores it in an opening direction, a fixed base frame 30 that fixes the storage section 20 to a wooden structure X, and a guide rail 40A that guides the opening and closing body 10 in the closing direction and the opening direction. This opening and closing device 1 employs a guide rail installation structure A as a structure for fixing a guide rail 40A to a wooden skeleton X.

[0010] Wooden structure X is a large building whose main material is wood. This wooden structure X is integrally equipped with a wooden base x1, a fuel portion x3 connected to the wooden base x1 and protruding forward from the wooden base x1, and a fire-resistant member x2 covering the wooden base x1 and the fuel portion x3 (see Figures 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 burning portion x3 is a piece of wood having a rectangular cross section (approximately square in the illustrated example) and extends vertically in an elongated shape. As shown in FIG. 3, the surroundings of this burning portion x3 are covered with a fire-resistant material x2, and the burning portion x3 is connected to the wooden base x1 by a plurality of fasteners M3 arranged vertically.

[0013] Each fastener M3 is a screw member (such as a screw) having a threaded portion m31 at its tip end and a head portion m32 at its rear end, and a plurality of fasteners M3 are provided at intervals in the vertical direction. Each fastener M3 has a head m32 engaged with the front side of the fuel portion x3, and a screw portion m31 penetrating the fuel portion x3 and the fire-resistant members x2, x2 on the other side thereof, and is screwed into the wooden base x1 (see FIG. 3).

[0014] The combustion portion x3 of the above configuration has its front side, its inner surface in the width direction of the opening / closing body (the left side in Figure 3), and its outer surface in the width direction of the opening / closing body each covered with multiple layers (two sheets in the illustrated example) of fire-resistant material x2.

[0015] 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 layered in one or more pieces (two sheets in the illustrated example) on the surfaces of the wooden base x1 and the burning portion x3. This fire-resistant material x2 prevents external heat and flames from being transmitted to the wooden base x1 and the fuel portion x3.

[0016] 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, the slats being formed by bending a horizontally elongated, generally rectangular metal plate. This opening / closing body 10 is sometimes called a slat shutter curtain. 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.

[0017] 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).

[0018] 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.

[0019] 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).

[0020] 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).

[0021] The support base frame 25 is formed by connecting a plurality of long hard members (for example, various steel materials such as angle iron and channel iron). The support base frame 25 in the illustrated example is integrally formed with a horizontally long connecting portion 25a that connects the left and right pivot support 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 fixed base frame 30 at the rear.

[0022] A lintel 26 is provided below the support base frame 25 so as to surround the opening and closing path of the opening and closing body 10 at the height of the ceiling 2. This lintel 26 is fixed to an immovable portion near the ceiling 2 (for example, the connecting portion 25a, the fixed base frame 30, or other immovable members on the ceiling side, etc.).

[0023] The fixed base frame 30 is configured as a generally rectangular frame in front view spanning substantially the entire width of the storage section 20 by connecting a plurality of long rigid members (square steel pipes in the illustrated example). A protruding portion 31 that protrudes upward is provided on the center side in the width direction of the fixed base frame 30. An upper and rear end portion of the above-mentioned support portion 25b is fastened to the protruding portion 31. The fixed base frame 30 is immovably fixed to the wooden structure X by fasteners (not shown) (for example, screws, bolts, anchor members, etc.).

[0024] The guide rails 40A are long members that are continuous vertically on both ends of the opening / closing body 10 in the width direction, and guide the width direction ends of the opening / closing body 10 in the opening / closing direction. In more detail, the guide rail 40A is hollow and integrally comprises a rail body 41 that guides the opening / closing body 10 in the vertical direction and a fastening bracket 42 for fastening the rail body 41 to the flame portion x3 (see FIG. 3). Each member constituting this guide rail 40A (in the illustrated example, the rail body 41, the fastening bracket 42, etc.) is formed from a hard metal material (for example, steel, stainless steel, aluminum alloy, etc.).

[0025] The rail main body 41 is a long, continuous member in the vertical direction, and is integral with a guide portion 41a that surrounds the widthwise end of the opening / closing body 10 with a concave cross section and guides it in the vertical direction, and a support portion 41b that supports this guide portion 41a on the outside in the widthwise direction of the opening / closing body (the right side in Figure 3) and connects it to the fastening bracket 42.

[0026] The fastening bracket 42 has a generally concave cross section that is continuous in a long shape in the vertical direction and has a plate-shaped portion 42a that contacts the front surface of the fuel portion x3 (more specifically, the fire-resistant member x2) and protrusions 42b, 42b that protrude forward from both the left and right ends of the plate-shaped portion 42a. The fastening bracket 42 is immovably fixed to the fuel portion x3 by a fastening tool M1.

[0027] The support portion 41b of the rail main body 41 is overlapped with the protruding pieces 42b, 42b on both sides of the previously fixed fastening bracket 42, and is fixed by fastening devices M2 (for example, screws, bolts, etc.).

[0028] The fastener M1 is a screw member (for example, a screw) having a threaded portion m11 at its front end and a head portion m12 at its rear end, and a plurality of fasteners M1 are provided at intervals in the vertical direction. Each fastener M1 has a head m12 at its rear end engaged with the fastener bracket 42 of the guide rail 40A, and a screw portion m11 at its tip end passed through the fastener bracket 42 and the fire-resistant members x2, x2 and screwed into the burn portion x3. The head m12 is covered by a closed air space a1 inside the guide rail 40A. This air space a1 prevents heat from outside the guide rail 40A from being transmitted to the fastener M1. The fastener M1 for fastening the guide rail 40A and the fastener M3 for fastening the burner portion x3 are at different height positions so as not to interfere with each other.

[0029] The guide rail 40A is also fixed to immovable portions at the upper and lower parts. More specifically, the lower end of guide rail 40A is fixed to a fixed portion on the lower side via bracket 45 (see FIG. 1). In the illustrated example, bracket 45 is an L-shaped angle member made of a rigid material, one side of which is fixed to guide rail 40A, and the other side of which is fixed to a fixed portion on the lower side, such as the floor surface, a door sill, or a bottom frame.

[0030] The upper end side of the guide rail 40A is inserted into the lintel 26 and fixed to the ceiling 2 or an immovable portion near the ceiling 2 (for example, the lintel 26, the fixed base frame 30, a beam-like member not shown, etc.).

[0031] Therefore, according to the guide rail installation structure A having the above configuration, the fuel portion x3 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40A. That is, for example, when the guide rail 40A is subjected to a flame, the heat and flame are transmitted to the fuel portion x3, and the fuel portion x3 is carbonized, and the carbonized layer exhibits good extinguishability. This makes it possible to prevent the flame from spreading to the wooden base x1 and to prevent the wooden base x1 from being thermally deteriorated.

[0032] Furthermore, even if the fastening strength of the fastening device M1 of the guide rail 40A is reduced due to thermal deterioration or burnout of the burnable portion x3, the guide rail 40A will not immediately collapse because its upper and lower ends are fastened to immovable parts on the floor and ceiling sides, respectively.

[0033] <Second embodiment> Next, an opening and closing device to which another example of the guide rail installation structure according to the present invention is applied will be described. In addition, since the guide rail installation structure described below is a modified portion of the above-mentioned guide rail installation structure A, parts that have approximately the same functions as the above-mentioned guide rail installation structure A will be given the same symbols and duplicate detailed descriptions will be omitted.

[0034] The guide rail installation structure B shown in FIG. 4 is obtained by removing the fire-resistant member x2 between the fuel portion x3 and the wooden base x1 from the guide rail installation structure A (see FIG. 3) and by replacing the guide rail 40A with a guide rail 40B. According to this guide rail installation structure B, the fuel portion x3 is directly connected to the wooden base x1, and the fuel portion x3 and the wooden base x1 as a whole are covered with multi-layered fire-resistant members x2, x2.

[0035] The guide rail 40B has a hollow support portion 41b side formed into a generally L-shaped cross section, and is fixed to the burnt portion x3 via a fastening bracket 42, a fastening tool M1, and the like. The head m12 of the fastener M1 is covered by a closed air space a1 within the guide rail 40B.

[0036] The guide rail 40B is provided to extend in the vertical direction, and like the guide rail 40A, the upper end side and the lower end side are each fixed to a fixed portion.

[0037] Therefore, according to the guide rail installation structure B shown in Figure 4, similarly to the guide rail installation structure described above, the combustion portion x3, etc. can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40B. Even if the burnable portion x3 is thermally deteriorated or burned, the guide rail 40B can be prevented from collapsing by the fastening points at the top and bottom of the guide rail 40B.

[0038] <Third embodiment> The guide rail installation structure C shown in Figure 5 is the above-mentioned guide rail installation structure A (see Figure 3) in which the guide rail 40A is replaced with a guide rail 40C, and the fastening portion of this guide rail 40C is placed in an air layer a2 covered by a fire-resistant member x2.

[0039] The guide rail 40C integrally comprises a rail body 41 that guides the opening / closing body 10 in the vertical direction and a fastening bracket 42 for fastening the rail body 41 to the burner portion x3, and each of these parts is formed from a hard metal material (e.g., steel, stainless steel, aluminum alloy, etc.).

[0040] The rail body 41 of the guide rail 40C has a guide portion 41a for inserting the width direction end of the opening / closing body 10 and guiding it in the closing direction. The guide portions 41a are formed in the shape of flat plates adjacent to both ends of the opening / closing body 10 in the width direction, and extend continuously in an elongated shape in the upward direction.

[0041] The fastening bracket 42 in the guide rail 40C is an angle-shaped member with an L-shaped cross section that is continued in the vertical direction, and one end of the bracket 42 is fastened to the rail main body 41 by a fastening device M2, and the other end of the bracket 42 is fastened to a burn-off portion x3 covered with fire-resistant members x2, x2 by a fastening device M1.

[0042] The guide rail 40C having the above-mentioned configuration has a portion that is attached to the burning fuel portion x3 disposed in the air layer a2 covered by the fire-resistant member x2, and the opening end side of the guide portion 41a is penetrated through the fire-resistant member x2 and exposed to the outside.

[0043] The guide rail 40C extends in the vertical direction, with its upper and lower ends each connected to a fixed portion.

[0044] The head m12 of the fastener M1 that fastens the guide rail 40C to the flame portion x3 is surrounded by an air layer a2, and the air layer a2 is further surrounded by a fire-resistant member x2 (see FIG. 5).

[0045] In the figure, reference symbol x5 denotes a support member that supports some of the fire-resistant members x2 from the inside, and is formed, for example, from a long rectangular columnar piece of wood that is continuous in the vertical direction.

[0046] Therefore, according to the guide rail installation structure C shown in FIG. 5, similarly to the above-mentioned guide rail installation structure, the combustion portion x3 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40C. Even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40C from collapsing.

[0047] <Fourth embodiment> The guide rail installation structure D shown in Figure 6 is the above-mentioned guide rail installation structure A (see Figure 3) in which the guide rail 40A is replaced with a guide rail 40D, and the fastening portion of this guide rail 40D is disposed in an air layer a2 covered by a fire-resistant member x2.

[0048] The guide rail 40D integrally comprises a rail body 41 and a fastening bracket 42 for fastening the rail body 41 to the flame portion x3, and each of these parts is formed from a hard metal material (e.g., steel, stainless steel, aluminum alloy, etc.).

[0049] The rail body 41 of the guide rail 40D has a concave cross section that surrounds the width direction end of the opening / closing body 10 and is continuous in the up-down direction. The fastening bracket 42 in the guide rail 40D is an angle-shaped member with an L-shaped cross section that is continued in the vertical direction, and one end of the bracket 42 is fastened to the rail main body 41 by a fastening device M2, and the other end of the bracket 42 is fastened to a burn portion x3 covered with fire-resistant members x2, x2 by a fastening device M1.

[0050] The head m12 of the fastener M1 is surrounded by a closed air space a2, and this air space a2 is further surrounded by the guide rail 40D, the fire-resistant member x2, and the like. The air layer a2 and the surrounding fire-resistant member x2 and the like prevent heat from outside the guide rail 40D from being transmitted to the head portion m12.

[0051] The guide rail 40D having the above-mentioned configuration is provided to extend in the vertical direction, and its upper end side and lower end side are each connected to a fixed portion.

[0052] Therefore, according to the guide rail installation structure D shown in FIG. 6, similarly to the above-mentioned guide rail installation structure, the fuel portion x3 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40D. Even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40D from collapsing.

[0053] <Fifth embodiment> A guide rail installation structure E shown in FIG. 7 is obtained by replacing the guide rail 40C in the guide rail installation structure C (see FIG. 5) with a guide rail 40E.

[0054] The guide rail 40E integrally comprises a rail body 41 that guides the opening / closing body 10 in the vertical direction and a fastening bracket 42 for fastening the rail body 41 to the burner portion x3, and each of these parts is formed from a hard metal material (e.g., steel, stainless steel, aluminum alloy, etc.).

[0055] The rail body 41 of the guide rail 40E has an opening end that is hemmed and bent to vertically guide the widthwise end of the opening / closing body 10.

[0056] The fastening bracket 42 of the guide rail 40E is located in the air space a2 surrounded by the fire-resistant member x2, and is fastened to the burning margin portion x3 by a fastening tool M1 arranged in the air space a2.

[0057] The upper and lower ends of the guide rail 40E are fixed to immovable portions.

[0058] According to the guide rail installation structure E shown in FIG. 7, similarly to the above-mentioned guide rail installation structure, the fuel portion x3 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40E. Even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40E from collapsing.

[0059] Sixth embodiment In the guide rail installation structure F shown in FIG. 8, a fuel portion x4 connects the guide rail 40F and the wooden base x1 inside a hollow guide rail 40F.

[0060] The guide rail 40F has a rail body 41 that guides the opening / closing body 10 in the up-down direction and is formed into a generally hollow L-shape in cross section. The rail bodies 41 are formed from a hard metal material (for example, steel, stainless steel, aluminum alloy, etc.).

[0061] The rail body 41 of the guide rail 40F is a long, vertically continuous member and has, integrally therewith, a guide portion 41a which surrounds the widthwise end of the opening / closing body 10 with a concave cross section to guide it in the vertical direction, and a support portion 41b which supports this guide portion 41a on the outside in the widthwise direction of the opening / closing body (the right side in Figure 3).

[0062] The support portion 41b of the guide rail 40F is formed with a cross section concave on the side facing the wooden base x1, and the burner portion x4 is fitted inside the cross section.

[0063] The burning portion x4 is formed in a long, continuous shape in the vertical direction using a wooden block or the like. The fuel portion x4 is fixed to the wooden base x1 by the fastener M3. That is, the fastener M3 has a screw portion m31 inserted through the fuel portion x4 and the fire-resistant members x2, x2 and screwed into the wooden base x1, and a head portion m32 engaged with the fuel portion x4.

[0064] The support portion 41b of the guide rail 40F is overlapped with the burnt portion x4 previously fixed as described above, and this overlapping portion is joined by the fastener M2. An air layer a1 is formed in the support portion 41b on the front side of the fuel portion x4. This air layer a1 prevents the heat from the outside of the guide rail 40F from being transmitted to the head portion m32 of the fastener M3.

[0065] In addition, reference numeral 43 in the figure denotes a metal plate-like reinforcing member that reinforces the rail main body 41. This reinforcing member 43 is provided so as to separate the air layer a1, and both ends in the opening / closing body width direction are joined to the inner surface of the rail main body 41.

[0066] The upper and lower ends of the guide rail 40F are each connected to an immovable portion.

[0067] In the guide rail 40F, the outer and inner (left and right sides in FIG. 8) outer surfaces of the support portion 41b in the opening / closing body width direction are covered with multi-layer fire-resistant members x2, x2, respectively.

[0068] Therefore, according to the guide rail 40F shown in FIG. 8, in substantially the same manner as the above-mentioned guide rail installation structure, the fuel portion x4 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40E. Even if the burnable portions x4 are thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40F from collapsing.

[0069] <Seventh embodiment> In the guide rail installation structure G shown in Fig. 9, a guide rail 40G is installed on the visible surface Xb of the frame opening. The guide rail 40G constitutes an opening / closing device in a manner substantially similar to that of the above embodiment, and surrounds the width direction end of the opening / closing body 10 extended from the upper storage section 20 in a concave shape to guide it in the vertical direction.

[0070] In this guide rail installation structure G, the wooden structure X is integrally equipped with a wooden base x1, multi-layered fire-resistant members x2, x2 covering the surface of the wooden base x1, a fire-resistant portion x3 that is connected to the wooden base x1 so as to be in contact with the surface of the fire-resistant member x2 and protrudes toward the inside in the width direction of the opening / closing body (the leftward direction in Figure 9), and multi-layered fire-resistant members x2, x2 covering the fire-resistant portion x3.

[0071] In the guide rail installation structure G, the fuel part x3 is fastened to the wooden base x1 by a plurality of fasteners M3 spaced apart in the vertical direction. That is, the screw part m31 of the fastener M3 penetrates the fire-resistant members x2, x2 and is screwed into the wooden base x1. The screw part m31 of the fastener M3 is engaged with the inner surface of the fuel part x3 in the width direction of the opening / closing body, and is covered by the fire-resistant members x2, x2.

[0072] The guide rail 40G is hollow and integrally includes a rail body 41 that guides the opening / closing body 10 in the up and down direction and a fastening bracket 42 that fastens the rail body 41 to the flame portion x3.

[0073] The rail body 41 of the guide rail 40G is a long, elongated member that continues in the vertical direction, and is integral with a guide portion 41a that surrounds the widthwise end of the opening / closing body 10 with a concave cross section and guides it in the vertical direction, and a support portion 41b that supports this guide portion 41a and connects it to the fastening bracket 42.

[0074] The fastening bracket 42 of the guide rail 40G has a generally C-shaped cross section that is continuous in a long shape in the vertical direction, and has a plate-shaped portion 42a that contacts the surface of the fire-resistant member x2 covering the burning portion x3, and protrusions 42b, 42b that protrude from both ends of the plate-shaped portion 42a toward the inside in the width direction of the opening / closing body (to the left in Figure 9). The fastening bracket 42 is fastened to the burnt portion x3 by a fastening tool M1. The guide rail 40G is fastened to the previously fixed fastening bracket 42 by a fastening tool M2.

[0075] Within the guide rail 40G, an air layer a1 closed by the rail body 41 and the fastening bracket 42 is provided around the head m12 of the fastening device M1. This air layer a1 prevents heat outside the guide rail 40G from being transmitted to the head m12.

[0076] The upper and lower ends of the guide rail 40G are fastened and fixed to immovable portions on the lower and upper sides, respectively.

[0077] Therefore, according to the guide rail installation structure G shown in FIG. 9, similarly to the above-mentioned guide rail installation structure, the fuel portion x3 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40G. Even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40F from collapsing.

[0078] <Eighth embodiment> In the guide rail installation structure H shown in Fig. 10, a guide rail 40H is installed on the visible surface Xb of the opening in the body via a burner portion x3. The guide rail 40H constitutes an opening and closing device in a manner substantially similar to that of the above embodiment, and surrounds the width direction end of the opening and closing body 10 that is extended from the upper storage section 20 in a concave shape to guide it in the vertical direction.

[0079] The guide rail 40H is provided with a heat insulating member 46 having lower thermal conductivity than the guide rail 40H inside the above-mentioned guide rail 40G (see FIG. 9) so as to cover the head m12 of the fastener M1. According to a preferred example of this embodiment, the heat insulating member 46 is a fire-resistant fiber member, and covers the head portion m12 of the fastener M1 so as to be in contact with the head portion m12.

[0080] In addition, the insulating member 46 can be made of fiber-based insulating materials such as glass wool, rock wool, cellulose fiber, and insulation board, foamed plastic insulating materials such as urethane foam and expanded polyethylene foam, natural material insulating materials such as carbonized cork, gypsum board, calcium silicate board, wood, etc.

[0081] The lower and upper ends of the guide rail 40H are fixed to immovable portions on the lower and upper sides, respectively.

[0083] 10, the guide rail 40H is subjected to heat from a fire, and the heat is effectively prevented from being transmitted to the fastener M1 by the heat insulating member 46. Even if the heat from a fire is transmitted to the fuel portion x3 through the fastener M1, the heat can be prevented from being further transmitted to the wooden base x1 by carbonization of the fuel portion x3. In addition, even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40H from collapsing.

[0084] <Ninth embodiment> In the guide rail installation structure I shown in Figure 11, the fire-resistant members x2, x2 between the fuel portion x3 and the wooden base x1 in the above-mentioned guide rail installation structure G (see Figure 9) are omitted, and the fuel portion x3 is in direct contact with the surface of the wooden base x1. A guide rail 40I in this guide rail installation structure I has the same configuration as the above-mentioned guide rail 40G.

[0085] According to this guide rail installation structure I, similarly to the above-mentioned guide rail installation structure G, the fuel portion x4 and the like can prevent heat and flames from being transmitted to the wooden base x1 via the guide rail 40I. Even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40F from collapsing.

[0086] <Tenth embodiment> In the guide rail installation structure J shown in Figure 12, the fire-resistant members x2, x2 between the fuel portion x3 and the wooden base x1 in the above-mentioned guide rail installation structure H (see Figure 10) are omitted, and the fuel portion x3 is in direct contact with the surface of the wooden base x1. A guide rail 40J in this guide rail installation structure J has the same configuration as the above-mentioned guide rail 40H.

[0087] According to this guide rail installation structure J, similarly to the above-mentioned guide rail installation structure H, the heat of the fire can be effectively prevented from being transmitted to the fastener M1 by the insulating member 46, and even if the burnable portion x3 is burned and carbonized, the carbonized layer can prevent the heat from being transmitted to the wooden base x1. Furthermore, even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40J from collapsing.

[0088] <Eleventh embodiment> In the guide rail installation structure K shown in Figure 13, similar to the above-mentioned guide rail installation structure G, the wooden structure X is composed of a wooden base x1, a fire-resistant member x2, and a burning portion x3, etc., and a guide rail 40K is connected to the fire-resistant member x2 covering the burning portion x3.

[0089] The guide rail 40K is integrally provided with a rail body 41 that guides the opening / closing body 10 in the vertical direction and a fastening bracket 42 for fastening the rail body 41 to the combustion portion x3, and is configured to be hollow on the fastening bracket 42 side having an air layer a1.

[0090] The rail body 41 of the guide rail 40K is made of a plurality of metal members and has a horizontal H-shaped cross section as shown in Fig. 13. The guide portions 41a of the rail body 41 are formed of flat plate-like members adjacent to the front and back surfaces of the opening / closing body 10.

[0091] The fastening bracket 42 of the guide rail 40K is a member having a U-shape in cross section with its opening facing inward in the width direction of the opening / closing body (left side in FIG. 13), and is fastened to the burner portion x3 by fastening tool M1. The rail body 41 fits inside the fastening bracket 42 that was previously fixed, and is fixed by fastening tool M2.

[0092] Between the rail body 41 and the fastening bracket 42, a closed air space a1 is provided so as to cover the head m12 of the fastening tool M1.

[0093] In addition, air layers a2, a2 ​​covered with fire-resistant material x2 are provided on both outer sides of the rail body 41 in the thickness direction of the opening / closing body (the lower and upper sides of the paper in FIG. 13). The part of the rail body 41 that is attached to the burning fuel part x3 is disposed in the air layer a2.

[0094] The fire-resistant member x2 around the air layer a2 exposes the tip side of the guide portion 41a, and covers the other portions with the air layer a2 therein. In addition, the symbol x5 in the figure denotes a support member that supports some of the fire-resistant members x2 from the inside, and is formed, for example, from a long rectangular column-shaped piece of wood that is continuous in the vertical direction.

[0095] The lower and upper ends of the guide rail 40K are fixed to immovable portions on the lower and upper sides, respectively.

[0096] Therefore, according to the guide rail installation structure K shown in Figure 13, the heat of a fire can be prevented from being transmitted to the fastening device M1 by the fire-resistant material x2 around the guide rail 40K and the air layers a2, a1, etc., and even if the burnable portion x3 burns and is carbonized, the carbonized layer can prevent the heat from being transmitted to the wooden base x1. In addition, even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40K from collapsing.

[0097] <Twelfth embodiment> A guide rail installation structure L shown in FIG. 14 is obtained by replacing the guide rail 40K in the guide rail installation structure K with a guide rail 40L.

[0098] The guide rail 40L is integrally formed with a rail body 41 that guides the opening / closing body 10 in the up-down direction and a fastening bracket 42 that fastens the rail body 41 to the flame portion x3.

[0099] The rail body 41 of the guide rail 40L has a cross section that is substantially H-shaped and has a guide portion 41a and a support portion 41b, as shown in Fig. 14. The end of the opening of the guide portion 41a is formed in a hemmed shape.

[0100] The fastening bracket 42 of the guide rail 40L is a member having a U-shape in cross section with its opening facing inward in the width direction of the opening / closing body (leftward in FIG. 14), and is fastened to the burner portion x3 by fastening tool M1. The rail body 41 fits inside the fastening bracket 42 that was previously fixed, and is fixed by fastening tool M2.

[0101] In the guide rail 40L, the fastening portion (more specifically, the fastening bracket 42 and the like) for the fuel portion x3 has an outer surface covered by an air layer a2 surrounded by the fire-resistant member x2.

[0102] The lower and upper ends of the guide rail 40L are fixed to immovable portions on the lower and upper sides, respectively.

[0103] Therefore, according to the guide rail installation structure L shown in Figure 14, the heat of a fire can be prevented from being transmitted to the fastening device M1 by the fire-resistant material x2 around the guide rail 40L and the air layers a2, a1, etc., and even if the burnable portion x3 burns and is carbonized, the insulating effect of the carbonized layer can prevent the heat from being transmitted to the wooden base x1. Furthermore, even if the burnable portion x3 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40L from collapsing. <Thirteenth embodiment> In the guide rail installation structure N shown in FIG. 15, similarly to the above-mentioned guide rail installation structure F (see FIG. 8), a fuel portion x4 connects the guide rail 40N and the wooden base x1 inside the hollow guide rail 40N.

[0104] The guide rail 40N includes a rail body 41 that guides the opening / closing body 10 in the up-down direction. The rail body 41 is integral with a guide portion 41a that surrounds the widthwise end of the opening / closing body 10 in a concave cross section and guides it in the up-down direction, and a support portion 41b that supports the guide portion 41a on the outer side in the widthwise direction of the opening / closing body (the right side in FIG. 15).

[0105] The support portion 41b of the guide rail 40N is formed with a cross section that faces the wooden structure X in a concave shape, and the burner portion x4 is fitted into the inside of the cross section.

[0106] The burning portion x4 is formed in a long, continuous shape in the vertical direction using a wooden block or the like. The fuel portion x4 is fixed to the wooden base x1 by the fastener M3. That is, the fastener M3 has a screw portion m31 inserted through the fuel portion x4 and the fire-resistant members x2, x2 and screwed into the wooden base x1, and a head portion m32 engaged with the fuel portion x4.

[0107] The support portion 41b of the guide rail 40N is overlapped with the burnt portion x4 that has been fixed in the above manner. Then, this overlapping portion is joined by the fastener M2. Within the support portion 41b, a closed air layer a1 is formed around the threaded portion m31 of the fastener M3. This air layer a1 prevents heat from outside the guide rail 40N from being transmitted to the head portion m32.

[0108] The upper and lower ends of the guide rail 40N are each connected to an immovable portion.

[0109] In the guide rail 40N, the outer surface except for a part of the guide portion 41a protruding inward in the width direction of the opening / closing body (the left end side in FIG. 15) is covered with multiple layered fire-resistant members x2, x2.

[0110] Therefore, according to the guide rail 40N shown in Figure 15, the heat of a fire can be prevented from being transmitted to the fastening device M1 by the fire-resistant material x2 around the guide rail 40N and the air layer a1, etc., and even if the burnable portion x4 is burned and carbonized, the insulating effect of the carbonized layer can prevent the heat from being transmitted to the wooden base x1. Furthermore, even if the burnable portion x4 is thermally deteriorated or burned, the upper and lower fastening points can prevent the guide rail 40N from collapsing.
