Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, due to relaxation of regulations on large-scale buildings in the Building Standards Law, etc., it has become more common to install heavy shutters at the openings of large wooden buildings. Therefore, for example, in the above prior art, it is conceivable to replace columnar steel materials with wooden columns to construct a wooden building, and fix high-weight opening / closing device components such as guide rails and shutter boxes to the wooden columns. However, according to such a configuration, in the unlikely event that a fire occurs and the opening / closing device is exposed to high heat, the heat is transmitted to the wooden column, and there is a risk that the fixing strength of the opening / closing device component decreases due to thermal deterioration of the wooden column, or the wooden column burns out.

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 opens and closes an opening formed in a wooden wall with an opening / closing body, wherein a wooden base extending in the vertical direction exists near the opening in the wooden wall, a metal column stands independently along the wooden wall and is independent of the wooden base, and a part of the opening / closing device is connected to the metal column. The installation structure of the opening / closing device is characterized by this.

Effects of the Invention

[0006] Since the present invention is configured as described above, it can strongly support the constituent members of the opening / closing device, and can prevent the heat received by the opening / closing device from being transmitted to the wooden base material.

Modes for Carrying Out the Invention

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

[0009] <First Embodiment> FIG. 1 shows an opening / closing device to which an opening / closing device installation structure according to an example of the present invention is applied. The opening / closing device 1 is a shutter device that opens and closes an opening a (see FIG. 3) between the left and right wooden walls x1, x1 in a wooden housing X, and constitutes a relatively large and 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 direction and the opening direction, and a storage unit 30 that extends the opening / closing body 10 in the closing direction or stores it in the opening direction. This opening / closing device 1 applies an opening / closing device installation structure A as the structure of the portion connected to the wooden wall x1 (in the illustrated example, the guide rail 20 and the storage unit 30).

[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 up and down. This opening / closing body 10 may be referred to as a slat shutter curtain. As another example of this opening / closing body 10, 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, etc. are possible.

[0011] The guide rail 20 is a long member that continues 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 the opening that is opened and closed by the opening / closing body 10 so as to guide the width direction end 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.) and is connected to the metal support P via a connection bracket 21 (see FIG. 3).

[0012] Note that the connecting means between the guide rail 20 and the connection bracket 21, and the connecting means between the connection bracket 21 and the metal support column P may be fixed with a fastener (for example, a screw, a bolt, a rivet, etc.) not shown in the figure, or may be welded.

[0013] 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 to reinforce them (see FIGS. 1 and 2).

[0014] 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 in a mode in which a winding body is rotatably supported on the outer periphery of a non-rotatable fixed shaft via a bearing, or in a mode in which a shaft portion integrated with the winding body is rotatably supported with respect to the shaft support bracket 32 via a bearing, etc.

[0015] 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 metal support column P on the rear side by fixing with a fastener (for example, a screw, a bolt, a rivet, etc.) not shown in the figure, or by welding. The connection portion between this shaft support bracket 32 and the metal support column P is covered with a low thermal conductivity member x12.

[0016] 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, and C-shaped steel). 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 same suspension reinforcement part 35 is connected to the metal beam p1 on the rear side of the storage part 30.

[0017] The metal beam p1 is a long member made of the same material as the metal support P, and one end side and the other end side thereof are connected to the left and right metal supports P and P, respectively.

[0018] Below the suspension reinforcement part 35, a cover part 26 is provided so as to surround the opening and closing path of the opening and closing body 10 at the height position of the ceiling part 2. This cover part 26 is fixed to a fixed part in the vicinity of the ceiling part 2 (for example, the receiving member 35a and other fixed members on the ceiling side).

[0019] The wooden building X is a large building mainly made of wood. This wooden building X has a wooden wall x1, and an opening a is formed at a predetermined position of this wooden wall x1. The wooden wall x1 has a wooden base x11 extending in the vertical direction near the opening a. And a metal support P that stands independently from the wooden base x11 is in contact with the outer surface of this wooden wall x1 (specifically, the end face on the opening a side).

[0020] Each wooden wall x1 integrally includes a wooden base x11 and low thermal conductivity members x12 and x13 that cover this wooden base x11 (see FIG. 3).

[0021] According to the illustrated example, the wooden base x11 is a wooden column and is continuously long in the vertical direction. The upper end side and the lower end side of this wooden base x11 are connected to other woods that make up the wooden building X. In addition, as another example of this wooden base x11, it is possible to use woods other than the illustrated example extending in the vertical direction, such as wooden structural plywood.

[0022] The low thermal conductivity members x12 and x13 are plate-like members made of a material having a lower thermal conductivity than the metal support P.

[0023] One of the low thermal conductivity members x12 is a plate-like fireproof member having heat insulation properties (for example, gypsum board, calcium silicate board, etc.). This low thermal conductivity member x12 covers the outer surfaces of the wooden base x11 and the metal support P, and also covers the connection part between the metal support P and the guide rail 20. Specifically, as shown in FIG. 3, the low thermal conductivity member x12 covers three surfaces, namely, the surface on the opening a side in the wooden base x11 and the surfaces on both sides in the expected direction in the same wooden base x11, in a multi-layered form (in the illustrated example, a two-layered form).

[0024] The other low thermal conductivity member x13 is a plate-like member made of a material different from that of the low thermal conductivity member x12, and covers all the outer surfaces of the low thermal conductivity member x12 and is exposed to the outside. This low thermal conductivity member x13 is, for example, a wooden decorative board and functions as a charring member. That is, when this low thermal conductivity member x13 is exposed to flames such as in the event of a fire, it forms a carbonized layer by combustion and becomes a good heat insulator. And the low thermal conductivity member x12 functions as a firestop member that prevents the flames from spreading inside.

[0025] The metal column P is a long member that is continuous in the vertical direction substantially parallel to the wooden base x11, and is formed in a hollow prismatic shape according to the illustrated example. The material of this metal column P may be, for example, iron (steel material), stainless steel, etc.

[0026] This metal column P is overlapped on the end face on the opening a side in the wooden wall x1 (the surface of the outer low thermal conductivity member x12). Therefore, a multi-layered low thermal conductivity member x12 is sandwiched between the wooden base x11 and the metal column P (see FIG. 3).

[0027] This metal column P is not supported by the wooden wall x1, and the upper end side and the lower end side are respectively connected to the immovable parts on the floor side and the ceiling side of the wooden structure X, so that it is independent and self-standing from the wooden wall x1. Specifically, the lower end portion of the metal column P is fixed to the lower immovable part (for example, the floor surface, the lower frame, the threshold, etc.) by a bracket p2 (see FIG. 1) such as an L shape, etc., and the upper end side of the metal column P is fixed to the upper immovable part (for example, the ceiling side member integrated with the wooden structure X, the beam material, etc.) by a bracket or the like not shown.

[0028] Then, the periphery of the connection portion between the guide rail 20 and the metal support column P (specifically, the connection bracket 21, etc.) is covered with a low thermal conductivity member x12 (or x13) with an air layer S interposed therebetween.

[0029] Also, the gap between the guide rail 20 and the low thermal conductivity member x12 (or x13) is filled with a fire-resistant sealing material x14. Specifically, as illustrated in FIG. 3, between the outer end surface in the width direction of the guide rail 20 and the end of the low thermal conductivity member x13 facing this end surface, and between the inner end surface of the guide rail 20 and the low thermal conductivity member x13 facing this end surface, there are respectively some gaps generated during the construction of the opening / closing device installation structure A. The fire-resistant sealing material x14 is filled into the gap in a fluid state and cures at room temperature to become an elastic body.

[0030] <Function and Effect> Therefore, according to the opening / closing device installation structure A with the above configuration, the component members of the opening / closing device 1 (according to the illustrated example, the guide rail 20 and the storage portion 30) can be firmly fixed, and the heat received by the opening / closing device 1 can be blocked by the low thermal conductivity members x12 and x13 on the outer surface side from being transmitted to the metal support column P and the wooden floor x11. Furthermore, the heat transmitted from the metal support column P to the wooden floor x11 can be blocked by the low thermal conductivity member x12 interposed therebetween. For this reason, even if a fire occurs and the opening / closing device 1 is exposed to high heat, it is possible to prevent the heat from being transmitted to the wooden floor x11 and prevent the wooden floor x11 from suffering heat deterioration or burning.

[0031] Moreover, it is of course possible to install the metal support column P at the construction stage of the wooden building structure X, and it is also possible to install this metal support column P after the construction of the wooden building structure X is completed (that is, retrofitted).

[0032] <Second Embodiment> Next, another example of the opening / closing device installation structure according to the present invention will be described. The opening / closing device installation structure shown below is a modified version of the above opening / closing device installation structure A. Therefore, mainly the modified parts will be described in detail, and the same reference numerals will be used for the parts that function in the same way as the above opening / closing device installation structure A.

[0033] The opening / closing device installation structure B shown in FIG. 4 is obtained by omitting the low thermal conductivity member x13 (combustion allowance member) from the above opening / closing device installation structure A (see FIG. 3), and the surface of the low thermal conductivity member x12 (fire-resistant member) is exposed to the outside air. In this opening / closing device installation structure B, the structure of the part where the storage part 30 is fixed to the metal support P is the same as that of the above opening / closing device installation structure A.

[0034] Therefore, according to the opening / closing device installation structure B shown in FIG. 4, the constituent members of the opening / closing device 1 (according to the illustrated example, the guide rail 20 and the storage part 30) can be firmly fixed, and the heat received by the opening / closing device 1 can be blocked by the low thermal conductivity member x12 on the outer surface side from being transmitted to the metal support P and the wooden floor x11. Furthermore, the heat transfer from the metal support P to the wooden floor x11 can be blocked by the low thermal conductivity members x12 interposed therebetween.

[0035] <The Third Embodiment> The opening / closing device installation structure C showing the cross-section of the main part in FIG. 5 has the metal support P embedded in the finding surface of the wooden wall x1.

[0036] Specifically, in this opening / closing device installation structure C, on the opening a side of the wooden floor x11, the low thermal conductivity members x12 (fire-resistant members) are interposed in multiple layers, and the metal support P is erected. The guide rail 20 is fixed to the front surface of this metal support P. Furthermore, on the opening a side of the metal support P, the low thermal conductivity members x12 are interposed in multiple layers, and the support member x15 extending in the vertical direction is erected. The outer surfaces of these wooden floor x11, metal support P, and support member x15 are covered with the low thermal conductivity members x12 and x13.

[0037] The support member x15 is a rectangular columnar wood that is long in the vertical direction, and the upper and lower ends are fixed to the immovable part on the ceiling side and the immovable part on the floor side, respectively. This support member x15 supports the surrounding low thermal conductivity member x12 from the inside. That is, the low thermal conductivity member x12 is overlapped on the outer surface of the support member x15 and fixed to the support member x15 by a fixing tool (for example, a nail or a screw).

[0038] In addition, this support member x15 also functions as a kindling member. That is, if the support member x15 catches fire due to a fire or the like, this support member x15 forms a carbonized layer to block the heat transfer.

[0039] In this opening and closing device installation structure C, the metal column P has its upper and lower ends fixed to the immovable part on the ceiling side and the immovable part on the floor side, and stands independently of the wooden base x11. This metal column P is embedded inside the low thermal conductivity member x12 so as to be substantially flush with the surface of the outer low thermal conductivity member x12.

[0040] A guide rail 20 is fixed to the front side surface of this metal column P, and a plurality of low thermal conductivity members x12 and x13 are overlapped on the rear side surface of the metal column P.

[0041] A wooden low thermal conductivity member x13 such as a decorative board is overlapped on the outermost low thermal conductivity member x12 covering the wooden base x11 and the support member x15. According to this configuration, the low thermal conductivity member x13 functions as a kindling member, and the low thermal conductivity member x12 (fire-resistant member) functions as a fire-stopping member.

[0042] In this opening and closing device installation structure C, the guide rail 20 penetrates the low thermal conductivity member x13 and is fixed to the surface of the metal column P by fixing with a fixing tool (for example, a bolt, a screw, a rivet, etc.) or welding.

[0043] In this opening and closing device installation structure C, the structure for fixing the storage part 30 to the metal column P is substantially the same as the above opening and closing device installation structure A.

[0044] Therefore, according to the opening and closing device installation structure C shown in FIG. 5, the constituent members of the opening and closing device 1 (according to the illustrated example, the guide rail 20 and the storage portion 30) can be firmly fixed, and the heat received by the opening and closing device 1 can be blocked from being transmitted to the metal support column P and the wooden floor x11 by the low heat conductivity members x12 and x13 on the outer surface side. Furthermore, the heat transmitted from the metal support column P to the wooden floor x11 can be blocked by the low heat conductivity member x12 interposed therebetween. In particular, in this opening and closing device installation structure C, since the metal support column P is embedded on one side in the thickness direction of the wooden wall x1, it is effective when a fire occurs on the other side in the same thickness direction is assumed.

[0045] <Fourth Embodiment> The opening and closing device installation structure D showing a cross-section of the main part in FIG. 6 is obtained by omitting the low heat conductivity member x13 (combustion margin member) and the fireproof sealing material x14 from the above opening and closing device installation structure C (see FIG. 5), and the surface of the low heat conductivity member x12 (fireproof member) is exposed to the outside air.

[0046] According to the opening and closing device installation structure D shown in FIG. 6, the constituent members of the opening and closing device 1 (according to the illustrated example, the guide rail 20 and the storage portion 30) can be firmly fixed, and the heat received by the opening and closing device 1 can be blocked from being transmitted to the metal support column P and the wooden floor x11 by the low heat conductivity member x12 on the outer surface side. Furthermore, the heat transmitted from the metal support column P to the wooden floor x11 can be blocked by the low heat conductivity member x12 interposed therebetween. Also, this opening and closing device installation structure D is also particularly effective when a fire occurs on the other side in the thickness direction of the wooden wall x1, since the metal support column P is embedded on one side in the thickness direction of the wooden wall x1.

[0047] <Fifth Embodiment> The opening and closing device installation structure E showing a cross-section of the main part in FIG. 7 has the metal support column P embedded at the corner where the end face on the opening a side in the wooden wall x1 intersects with one finding surface (the front side surface in the illustrated example) of the same wooden wall x1.

[0048] Specifically, in this opening and closing device installation structure C, the metal support column P is arranged closer to the opening a and closer to the front with respect to the wooden base x11. The upper and lower ends of the metal support column P are fixed to the immovable part on the ceiling side and the immovable part on the floor side, and it stands independently from the wooden base x11.

[0049] A low thermal conductivity member x12 (fire-resistant member) is provided in a multi-layered manner between the wooden base x11 and the metal support column P. This low thermal conductivity member x12 covers the surroundings of the wooden base x11 and the metal support column P except for the connection part between the metal support column P and the guide rail 20. In FIG. 7, the reference sign x16 is a support member that supports the low thermal conductivity member x12 from the inside, and is formed of, for example, a rectangular columnar wood.

[0050] The outermost low thermal conductivity member x12 has its outer surface covered by a low thermal conductivity member x13 (combustion margin member) such as a decorative board, and the inner low thermal conductivity member x13 functions as a fire-stopping member.

[0051] To the metal support column P with the above configuration, a guide rail 20' is connected so as to cover the corner where the prospective surface (the surface on the opening a side) and the front finding surface intersect.

[0052] The guide rail 20' is integrally provided with a finding side joint portion 20a connected to the finding surface of the metal support column P and a prospective side joint portion 20b connected to the prospective surface of the metal support column P. The finding side joint portion 20a and the prospective side joint portion 20b are connected to the metal support column P by fixing with a fastener (for example, a screw, a bolt, a rivet, etc.) or welding.

[0053] On the prospective surface side of the metal support column P, a fire-resistant sealing material x14 is filled in the concave portion between the guide rail 20 and the end of the low thermal conductivity member x13 so as to cover the prospective side joint portion 20b. Also, on the finding surface side of the metal support column P, a fire-resistant sealing material x14 is filled in the concave portion between the guide rail 20 and the end of the low thermal conductivity member x13.

[0054] In this opening / closing device installation structure E, the structure of the portion for fixing the storage part 30 to the metal column P is substantially the same as that of the above-described opening / closing device installation structure A.

[0055] Therefore, according to the opening / closing device installation structure E shown in FIG. 7, the constituent members of the opening / closing device 1 (in the illustrated example, the guide rail 20 and the storage part 30) can be firmly fixed, and the heat received by the opening / closing device 1 can be blocked from being transmitted to the metal column P and the wooden floor base x11 by the low heat conductivity member x12 on the outer surface side. Further, the heat transmission from the metal column P to the wooden floor base x11 can be blocked by the low heat conductivity member x12 interposed therebetween. Also, since this opening / closing device installation structure E also embeds the metal column P on one side in the thickness direction of the wooden wall x1 (the front side in the illustrated example), it is particularly effective when a fire is assumed to occur on the other side in the same thickness direction. <Sixth Embodiment> The opening / closing device installation structure F showing a cross-section of the main part in FIG. 8 is obtained by omitting the low heat conductivity member x13 (burning allowance member) and the fireproof sealing material x14 from the above-described opening / closing device installation structure E (see FIG. 7), and the surface of the low heat conductivity member x12 (fireproof member) is exposed to the outside air.

[0056] Therefore, according to the opening / closing device installation structure F shown in FIG. 8, the constituent members of the opening / closing device 1 (in the illustrated example, the guide rail 20 and the storage part 30) can be firmly fixed, and the heat received by the opening / closing device 1 can be blocked from being transmitted to the metal column P and the wooden floor base x11 by the low heat conductivity member x12 on the outer surface side. Further, the heat transmission from the metal column P to the wooden floor base x11 can be blocked by the low heat conductivity member x12 interposed therebetween. Also, since this opening / closing device installation structure F also embeds the metal column P on one side in the thickness direction of the wooden wall x1, it is particularly effective when a fire is assumed to occur on the other side in the same thickness direction.

[0057] <Other Modification Examples> According to the illustrated example, the suspension reinforcement portion 35 is fixed to the metal beam p1. As another example, a rectangular frame-shaped member to be fixed may be provided on the front side of the left and right metal columns P, P, and the storage portion 30 may be fixed to this member to be fixed.

[0058] Further, in the above embodiment, as a preferable example of the opening / closing device installation structure, both the guide rail 20 and the storage portion 30 are fixed to the metal column P. However, in the present invention, only the guide rail 20 is fixed to the metal column P, and the storage portion 30 is directly fixed to a member other than the metal column P (for example, the wooden floor x11), or only the storage portion 30 is fixed to the metal column P, and the guide rail 20 is directly fixed to a member other than the metal column P (for example, the wooden floor x11). It is also possible to adopt a mode or the like.

[0059] Further, in the above embodiment, the gap between the low heat conductivity member x13 and the guide rail 20 is filled with the fire-resistant sealing material x14. As another example, the gap between the low heat conductivity member x12 and the guide rail 20 may be filled with the fire-resistant sealing material x14.

[0060] Further, the present invention is not limited to the above-described specific configuration, and can be appropriately changed without changing the gist of the present invention.
