Description

[Technical field]

[0001] The present invention relates to a storage unit installation structure in which a storage unit for storing an opening / closing body is supported on a wooden framework. [Background technology]

[0002] A typical shutter device comprises an opening / closing body that operates to close the space, a guide rail that guides the opening / closing body in the vertical direction, and a storage section (shutter box) that stores the opening / closing body above it. 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, since the storage section is relatively heavy, there is a risk that the strength of the wooden structure supporting the storage section and the strength of the fastening parts using screws, etc. may be insufficient. In view of this, there is a conventional technique in which a sturdy support (base member) made of, for example, a steel frame is fixed to a wooden structure to reinforce the wooden structure, and a storage section is attached to the support (see Patent Document 1). In this conventional technique, the support body is overlapped and secured to a hanging portion on the ceiling side of a wooden structure (for example, a dropped ceiling or beams) from the front side (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-031930 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, if there is no hanging portion as described above, some ingenuity is required to fix the support body to the wooden structure. [Means for solving the problem]

[0005] In view of the above problems, one aspect of the present invention has the following configuration. A storage unit installation structure in which a storage unit for storing an opening / closing body is supported on a wooden structure, characterized in that a support body supporting the storage unit is fastened to the wooden structure located to the side. Effect of the Invention

[0006] Since the present invention is configured as described above, it is possible to fix a storage section to a wooden frame having no hanging portion on the ceiling side. [Brief description of the drawings]

[Figure 8] 8(a) and 8(b) are front views sequentially showing a procedure for attaching the support body of FIG. 7 to a wooden skeleton. [Figure 9] FIG. 8 is a cross-sectional view taken along line (IX)-(IX) in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0009] <First embodiment> FIG. 1 shows an opening and closing device to which an example of a storage section installation structure according to the present invention is applied. The opening / closing device 1 includes an opening / closing body 10 that performs a closing operation so as to partition a space, a storage section 20 that advances the opening / closing body 10 in the closing direction and stores it in the opening direction, and a guide rail 40 that guides the opening / closing body 10 in the closing direction and the opening direction.

[0010] This opening / closing device 1 has a storage section 20 fixed to a side wall surface Xb of a wooden structure X above an opening so that the opening of the wooden structure X can be opened and closed by an opening / closing body 10, and a storage section installation structure A is applied as the fixing structure.

[0011] The storage unit installation structure A includes a support body 30 that supports the storage unit 20, and this support body 30 is fastened to a side wall surface Xb of a wooden structure X located laterally by a fastener 38 (see FIG. 3).

[0012] Wooden structure X is a large building whose main material is wood. This wooden structure X is integrally provided with a wooden base x1 and a fire-resistant member x2 that covers the wooden base x1 (see FIG. 3). The wooden structure X has a wall surface Xb that is above the opening that is opened and closed by the opening / closing body 10 and continues in the front direction (left and right direction in FIG. 2) to the side of the storage section 20 (left and right direction in FIG. 3). The side wall surface Xb may be, for example, a side wall surface of an opening, a passage, or the like in which the opening / closing body 10 is installed.

[0013] In the illustrated example, there is no wall surface such as a lowered wall at the rear of the storage section 20 (on the right side in FIG. 2).

[0014] The wooden base x1 is a wooden building material that constitutes the basic framework of the wooden structure X, and is, for example, a rectangular column-shaped piece of wood that constitutes a beam or a flat structural plywood that constitutes a wall surface.

[0015] The fire-resistant member x2 is a plate-shaped building material having fire resistance and heat insulation properties (such as a gypsum board or a calcium silicate board), and one or more fire-resistant members x2 (two in the illustrated example) are layered on the surface of the wooden base x1. This fire-resistant material x2 prevents external heat and flames from being transmitted to the wooden base x1.

[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 such as a fire-resistant 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 that is a driving source that drives and rotates the winding shaft 21, and a support base frame 25 that holds the pivot brackets 22, 22, etc. together (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 member 25a that connects the left and right pivot support brackets 22, 22 at their lower ends, and a support part 25b that is substantially U-shaped in side view and supports a substantially central portion in the width direction of the connecting member 25a and is fastened to the rear support body 30.

[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 material 25a, the support 30, other immovable members on the ceiling side, etc.).

[0023] The guide rails 40 are long members that continue in the vertical direction on both ends of the opening / closing body 10 in the width direction. The guide rails 40 are disposed on both sides of the opening that is opened and closed by the opening / closing body 10 so as to guide the widthwise ends of the opening / closing body 10 in the opening / closing direction. The guide rail 40 is formed from a hard metal material (such as steel, stainless steel, or an aluminum alloy) and is fixed to the wooden structure X by fasteners (such as screws, bolts, or rivets) not shown.

[0024] In addition, the lower end of the guide rail 40 is fixed to a fixed part on the lower side (e.g., the floor surface, the bottom frame, the door sill, etc.) via a bracket 47 (see Figure 1), and the upper end of the guide rail 40 is fixed to a fixed part on the upper side (e.g., the lintel portion 26, the ceiling portion 2, the steel material on the upper side, the beam material, etc.) via a bracket (not shown).

[0025] The support body 30 is formed by connecting a plurality of long rigid members (square steel pipes in the illustrated example) and has a generally rectangular frame shape in front view spanning substantially the entire length of the storage section 20 in the width direction.

[0026] The support body 30 shown in Fig. 3 is integrally formed of two horizontal frame members 32, 35 spaced apart in the vertical direction, connecting members 33, 33 connecting the horizontal frame members 32, 35 at both ends in the width direction, a connecting member 34 connecting the horizontal frame members 32, 35 at the center in the width direction, and a protruding portion 31 protruding upward from the center in the width direction of the upper horizontal frame member 32. The upper rear end side of the support portion 25b is attached to the protruding portion 31.

[0027] Each member constituting the support body 30 (in the illustrated example, the horizontal frame members 32, 35, the connecting member 33, the protruding portion 31, etc.) is made of a hard metal material (e.g., iron, aluminum alloy, stainless steel, etc.). These members are integrally connected by an appropriate connecting means (e.g., welding, screwing, riveting, fitting, etc.).

[0028] The upper horizontal frame member 32 and the lower horizontal frame member 35 have approximately the same length in the width direction. One end and the other end of these horizontal frame members 32, 35 are each connected to the side of a connecting member 33.

[0029] The connecting material 33 has, at its upper end, a protruding portion 33a that extends so as to protrude upward beyond the upper horizontal frame material 32.

[0030] In the connecting member 33, the portion between the upper and lower horizontal frame members 32, and the protruding portion 33a are fastened to the lateral wooden structure X (side wall surface Xb) by fasteners .

[0031] <An example of manufacturing procedure> Next, a procedure for mounting the support body 30 having the above-mentioned structure between the left and right side wall surfaces Xb, Xb will be described in detail. First, the support body 30 having the above-mentioned structure is fitted between the left and right side wall surfaces Xb, Xb and aligned as shown in FIG. At this time, a plate-shaped spacer or the like may be sandwiched between each connecting member 33 of the support body 30 and the side wall surface Xb, if necessary.

[0032] In the above-mentioned work, as shown in FIG. 5, the support body 30 may be fitted between the left and right side wall surfaces Xb, Xb from below. As another example, the support body 30 may be fitted between the left and right side wall surfaces Xb, Xb from above, the front, or the back.

[0033] Next, the left and right end sides of the support body 30 are fastened to the side wall surface Xb by fasteners 38, respectively. More specifically, in each of the left and right connecting members 33, the portion between the upper horizontal frame member 32 and the lower horizontal frame member 35 and the upwardly protruding protrusion 33a are each fastened to the side wall surface Xb by fasteners 38.

[0034] Each fastener 38 is a fastener (for example, a screw, a bolt, an anchor member, a nail, or the like) having a head at the rear end of a shaft portion. The fastener 38 is used so as to have a vertical tolerance (approximately horizontal in the illustrated example), and its tip end penetrates the connecting material 33 and the fire-resistant members x2, x2 and is inserted into the wooden base x1. For example, if the fastener 38 is a screw, the threaded portion on the tip end is screwed into the wooden base x1 (see FIG. 4).

[0035] Thereafter, the pivot brackets 22 are attached to the left and right end sides of the support body 30 (see FIG. 3), and the storage section 20 is assembled.

[0036] As shown in FIG. 2, the outer surface of the support 30 is covered with a fire-resistant member x2. More specifically, the entire support 30 is covered with multiple layers of fire-resistant members x2 formed in a hollow frame shape as shown in Fig. 2. Therefore, the outer surface of the support 30 is not directly exposed to the outside air. Also, the head of the fastener 38 located between the horizontal frame member 32 and the horizontal frame member 35 is located in an air layer surrounded by the upper and lower horizontal frame members 32, 35, the connecting members 33, 34, the fire-resistant members x2, etc.

[0037] <Action and effect> Therefore, according to the storage unit installation structure A having the above-mentioned configuration, even if the installation target portion of the opening and closing device 1 does not have a hanging portion of the wooden structure X, such as a hanging wall or beam material, the support body 30 can be sturdily installed by utilizing the side wall surface Xb. Moreover, since the fasteners 38 are inserted between the upper and lower horizontal frame members 32, 35 of the connecting member 33 and through the protruding portion 33a, workability is good.

[0038] In addition, since the support 30 is fastened to the side wall surface Xb by the fasteners 38 that cross the vertical direction, the weight of the storage section 20 including the support 30 acts as a shear force on each fastener 38. Therefore, compared to a configuration in which the support 30 is suspended by fasteners in the vertical direction, it is easier to maintain high strength and durability at the fastening points by the fasteners 38.

[0039] Furthermore, since the outer surface of the support 30 is covered with the fire-resistant member x2 and the head of the fastener 38 between the horizontal frame member 32 and the horizontal frame member 35 is located in the air layer covered by the fire-resistant member x2 (see FIG. 2), even if a fire occurs, the support 30 and the fastener 38 are unlikely to be affected by the heat. This makes it possible to prevent high heat from the fire from being transferred from the fastener 38 to the wooden base x1, causing thermal deterioration of the fastening portion of the fastener 38 on the wooden base x1, and preventing the fastener 38 from coming loose due to this thermal deterioration.

[0040] <Second embodiment> Next, another example of the storage unit installation structure according to the present invention will be described. Note that the storage unit installation structure shown below is obtained by modifying the form of the support body 30 in the storage unit installation structure A, so the modified support body will be mainly described in detail, and the same reference numerals will be used for parts that function in the same way as in the storage unit installation structure A.

[0041] A support 30' shown in FIG. 6 is obtained by replacing the connecting member 33 of the support 30 with a connecting member 33'.

[0042] The connecting material 33' is the same as the connecting material 33, except that a protruding portion 33b is provided so as to extend downward beyond the lower horizontal frame material 35. The connecting member 33' is fastened to the side wall surface Xb of the wooden structure X by fasteners 38 which are inserted through the protruding portion 33a, the portion between the horizontal frame member 32 and the horizontal frame member 35, and the protruding portion 33b.

[0043] The pivot bracket 22 is fixed to the connecting member 33' having the above-mentioned configuration in substantially the same manner as the connecting member 33, and the storage section 20 is assembled thereto. If necessary, the outer peripheral surface of the connecting material 33' is covered with a fire-resistant member x2 in the same manner as the connecting material 33 (see FIG. 2).

[0044] Therefore, the storage section installation structure having the support body 30' shown in Figure 6 not only achieves substantially the same effect as the storage section installation structure A having the support body 30, but also further improves the fastening strength by the fastening device 38 provided on the protruding portion 33b.

[0045] <Third embodiment> 7 to 9 show another example of a storage unit installation structure according to the present invention. In this storage unit installation structure, a fixed base x3 is fixed integrally to a wooden skeleton X, and a support 30" for supporting a storage unit 20 is fastened to the wooden skeleton X via a fixed base 50.

[0046] The fixed base 50 is integrally formed by a rectangular columnar core material 50a extending in the vertical direction, and a fire-resistant member x2 covering the entire outer surface of the core material 50a in a multi-layered manner.

[0047] The core material 50a is a generally columnar piece of wood that is continuous in the vertical direction. The fire-resistant members x2 cover all the side surfaces and the upper and lower end surfaces of the core material 50a in a multi-layered manner (two layers in the illustrated example) (see FIG. 9).

[0048] 8(a), the fixing base 50 having the above-mentioned configuration is fixed in advance to a side wall surface Xb of a wooden skeleton X by a plurality of fasteners 53 (e.g., screws, bolts, anchor members, nails, etc.). The fasteners 53 in the illustrated example are screws that penetrate the core material 50a and are screwed into the wooden skeleton X.

[0049] Then, the support body 30" is fitted to the left and right fixed bases 50, 50 fixed to the wooden structure X. This support body 30" is connected to the fixed base 50 by vertical and horizontal fasteners 51, 52 (e.g., screws, bolts, anchor members, nails, etc.) (see Figure 7).

[0050] The support body 30" is integrally constituted by two horizontal frame members 32", 35" spaced apart in the vertical direction, connecting members 33", 33" that connect these horizontal frame members 32", 35" at both ends in the width direction, a connecting member 34 that connects these horizontal frame members 32", 35" at their centre, and a protrusion 31 that protrudes upward from the centre of the upper horizontal frame member 32. The upper rear end side of the support portion 25b is attached to the protrusion 31. The materials of these members are the same as those of the support 30 described above.

[0051] The upper horizontal frame member 32'' is longer than the lower horizontal frame member 35'', and the lower surfaces of one and the other ends in the width direction are each connected to the upper end of the connecting member 33''. The lower horizontal frame member 35'' has one end and the other end in the width direction connected to the side of the connecting member 33''.

[0052] One and the other ends of the horizontal frame member 32 ″ protrude outward in the width direction beyond the connecting member 33 so as to be received by the upper end of the fixed base 50 .

[0053] The support body 30" having the above-mentioned structure is fitted between the left and right fixed bases 50, 50, and the left and right protruding portions of the upper horizontal frame member 32" are received by the upper ends of the fixed bases 50, respectively (see FIG. 8). The fixed base 50 is secured to the fixed base 50 by a fastener 51 that penetrates the horizontal frame member 32'' from top to bottom and a fastener 52 that penetrates the connecting member 33'' from the inside to the outside in the width direction. In the illustrated example, the lateral fasteners 52 are screws that are screwed into the fixed base 50, but the fasteners 52 may also pass through the fixed base 50 and be screwed into the wooden structure X.

[0054] Therefore, according to the support body 30'' and the storage section installation structure shown in Figs. 7 to 9, substantially the same effects as those of the above-described embodiment (see Figs. 1 to 6) can be achieved, and in addition, the workability when attaching the support body 30'' to the wooden skeleton X is further improved.

[0055] <Other Modifications> According to the above embodiment, the core material 50a of the fixed base 50 is made of wood, which is particularly easy to process. However, the core material 50a may be made of a hard material other than wood, such as metal.

[0056] According to the embodiment shown in Figures 7 and 8, the end side of the upper horizontal frame member 32" of the support body 30" is supported by the fixed base 50. As another example, the lower horizontal frame member 35" of the support body 30" may be supported by the fixed base 50.

[0057] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without departing from the gist of the present invention.
