Description

[Technical field]

[0001] The present invention relates to a storage section installation structure in which a storage section for storing an opening / closing body is supported on a wooden framework, and to a manufacturing method for this storage section installation structure. [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). [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, according to the conventional technology, the support body increases the weight of the storage section, and there is a risk that the strength of the fastening portion of the support body to the wooden structure may be insufficient. [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 and closing body is supported on a wooden structure, the storage unit installation structure comprising a support body that supports the storage unit and a fixed base that is fixed to the wooden structure, the support body being supported from below by the fixed base. Effect of the Invention

[0006] Since the present invention is configured as described above, the strength deficiency of the connection portion of the support can be compensated for by the fixed base. [Brief description of the drawings]

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 unit 20 fixed to a wall surface Xa above an opening Ap of a wooden structure X so that the opening Ap of the wooden structure X is opened and closed by an opening / closing body 10, and a storage unit installation structure A is applied as the fixing structure.

[0011] The storage unit installation structure A comprises a support body 30 that supports the storage unit 20 and a fixed base 50 that is fixed to a wooden structure X, and the support body 30 is supported from below by the fixed base 50 (see Figures 2 and 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.

[0013] 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. The wooden base x1 in the illustrated example is provided above the opening Ap that is opened and closed by the opening / closing body 10, across the width direction.

[0014] 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.

[0015] 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.

[0016] 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 the driving source that drives and rotates the winding shaft 21, and a support base frame 25 that supports and holds the pivot brackets 22, 22 together (see Figures 1 and 2).

[0017] 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.

[0018] 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).

[0019] 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).

[0020] 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 supports a substantially central portion in the width direction of the connecting member 25a and is fastened to the rear support body 30.

[0021] 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.).

[0022] The guide rails 40 are long members that are continuous vertically on both ends of the opening / closing body 10 in the width direction. The guide rails 40 are fixed to the wall surfaces on both sides of the opening Ap in the wooden structure X 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.

[0023] 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, 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.

[0024] The support body 30 is formed by connecting a plurality of long rigid members (square steel pipes in the illustrated example) to have a generally rectangular frame shape in front view spanning generally the entire width of the storage section 20 (see FIG. 3).

[0025] The support body 30 in the illustrated example is integrally formed of a plurality of horizontal frame members 32, 32 (two in the illustrated example) spaced apart in the vertical direction, connecting members 33, 33 connecting the horizontal frame members 32, 32 at both ends in the width direction, a connecting member 34 connecting the horizontal frame members 32, 32 at their centers, and a protruding portion 31 protruding upward from the center of the upper horizontal frame member 32. The upper rear end portion of the support portion 25b is attached to the protruding portion 31.

[0026] Each member constituting the support body 30 (in the illustrated example, the horizontal frame member 32, the connecting member 33, the protruding portion 31, etc.) is made of a hard metal material (for example, iron, aluminum alloy, stainless steel, etc.). These members are integrally connected by welding or the like.

[0027] The pivot brackets 22 are fastened to the connecting members 33, 33 on both ends (see FIG. 3). The fastening may be achieved by fastening with fasteners such as bolts or anchors, or by welding.

[0028] The support body 30 having the above-mentioned configuration is immovably fixed to a wall surface Xa of a wooden structure X by fasteners 38 (for example, screws, bolts, anchor members, nails, etc.), and is supported by a fixed base 50 from below.

[0029] The fixed base 50 is continuous and elongated across the width of the support 30, and is provided so as to receive at least one of the multiple horizontal frame members 32 constituting the support 30 from below. According to a preferred example shown in FIG. 3, the fixed base 50 is provided so as to receive the lower horizontal frame member 32 from below, out of the upper and lower horizontal frame members 32, 32.

[0030] The fixed base 50 is integrally formed by a long, continuous core material 50a in the horizontal direction and fire-resistant members x2, x2 that cover the entire outer surface of the core material 50a in a multi-layered manner, and is fastened to a wooden base x1 by a fastener 38.

[0031] The core material 50a is a piece of wood that spans the width of the support 30, and is fastened to the wooden skeleton X by a plurality of fasteners 38 spaced apart in the width direction. Each fastener 38 for fastening the core material 50a is used in a horizontal direction substantially perpendicular to the vertical direction, penetrates the core material 50a, and has its tip side screwed into the wooden base x1.

[0032] If each fastener 38 were used facing upward, a load would be applied to each fastener 38 in the removal direction, but according to a preferred example of this embodiment, since each fastener 38 is inserted sideways, the load applied from above to the fixed base 50 acts as a shear force on each fastener 38. Therefore, compared to the former case in which a load is applied to the fastener 38 in the removal direction, durability against the load of the support 30, etc. is good.

[0033] The fire-resistant member x2 covering the core material 50a may be made of the same material as the fire-resistant member x2 covering the wooden base x1, but may be made of a different material or have a different thickness. The fire-resistant member x2 prevents heat and flames from a fire from being transmitted to the core material 50a.

[0034] The core material 50a is not easily affected by heat from a fire or the like because it is covered with the fire-resistant member x2, but in the unlikely event that it is carbonized due to the heat of a fire or the like, the insulating properties of the carbonized layer prevent the heat of the fire or the like from being transmitted to the wooden base x1. In other words, the wooden core material 50a has both the function of receiving the support 30 and the function of a substitute member.

[0035] In addition, other examples of the core material 50a include materials other than wood, such as steel and ceramic.

[0036] <About the manufacturing method of the storage unit installation structure> Next, the features of the manufacturing method of the storage section installation structure A having the above configuration will be described in detail (see FIG. 4).

[0037] When the support body 30 is fixed to the wall surface Xa of the wooden structure X, first, the core material 50a is fastened to the wooden structure X by the fastener 38 (see FIG. 4(a)). A multi-layer fire-resistant member x2 is provided so as to cover the outer surface of the core material 50a.

[0038] Next, the support body 30 is placed on the upper surface of the fixed base 50 and overlapped with the wall surface Xa. Then, the support body 30 is fastened to the wooden skeleton X by a plurality of fasteners 38. Thus, according to this manufacturing method, the support 30 can be easily positioned in the height direction, and the support 30 can be placed on the fixed base 50 for work, so that the workability is excellent.

[0039] Thereafter, the left and right pivot brackets 22, 22 are fastened to the support body 30 fixed to the wooden structure X, and the storage section 20 is assembled.

[0040] As another example of a manufacturing method for the storage unit installation structure A, as shown in Figs. 5(a) and (b), the support 30 may be first fixed to the wooden structure X, and then the fixed base 50 may be abutted against the support 30 from below, and the fixed base 50 may be fixed to the wooden structure X. According to this alternative manufacturing method, the strength of the support 30 can be improved by installing the fixed base 50 after the support 30 and the storage section 20 are attached first.

[0041] <Action and effect> Therefore, according to the storage unit installation structure A and its manufacturing method configured as described above, the fixed base 50 can compensate for the lack of strength of the connection portion of the support 30 to the wooden skeleton X. Moreover, the workability when connecting the support 30 to the wooden skeleton X is also good. Also, it is possible to make the core material 50a of the fixed base 50 function as a substitute material.

[0042] <Second embodiment> Next, an opening and closing device to which another embodiment of the storage section installation structure according to the present invention is applied will be described. The storage unit installation structure described below is a modified version of the storage unit installation structure A, and so the modified parts will be mainly described in detail below. The parts that function in the same way as the storage unit installation structure A will be given the same reference numerals and will not be described in detail again.

[0043] The opening and closing device shown in FIG. 6 is obtained by replacing the storage unit installation structure A with a storage unit installation structure B in the opening and closing device 1 described above. The storage unit installation structure B is similar to the storage unit installation structure A except that the fire-resistant members x2, x2 between the core material 50a and the wooden base x1 are omitted, and the core material 50a is in direct contact with the wooden base x1.

[0044] That is, in the process of constructing the wooden skeleton X in this storage unit installation structure B, the core material 50a is directly fastened to the vertical surface of the wooden base x1 by the fasteners 38. Then, the wooden base x1 and the core material 50a are covered in multiple layers with the fire-resistant member x2.

[0045] In this way, the wall surface Xa is formed with a fixed base portion 50 that is continuously formed in the width direction and protrudes toward the front side (left side in FIG. 6) and has a generally horizontally convex shape in vertical cross section. The support 30 is received on the fixed base 50 and is fastened to the wooden base x1 by the fasteners 38.

[0046] 6 and its manufacturing method, the storage unit installation structure B can compensate for the lack of strength of the connection portion of the support 30 to the wooden structure X by the fixed base 50, in a manner similar to the storage unit installation structure A. Moreover, the workability when connecting the support 30 to the wooden structure X is also good. Also, the core material 50a of the fixed base 50 can function as a substitute material.

[0047] <Third embodiment> The opening and closing device shown in FIG. 7 is obtained by replacing the storage unit installation structure A with a storage unit installation structure C in the opening and closing device 1 described above. The storage unit installation structure C is obtained by moving the fixed base 50 in the storage unit installation structure A to between the upper and lower horizontal frame members 32.

[0048] A plurality of fixed bases 50 are provided at intervals in the width direction (see FIG. 8). Each fixed base 50 receives an upper horizontal frame member 32 from below.

[0049] In the storage unit installation structure C, the support body 30 is fixed to the wooden structure X by fasteners 38 with the upper horizontal frame member 32 received by a plurality of fixed bases 50.

[0050] The lower end surface of the support body 30 (more specifically, the lower end surface of the lower horizontal frame member 32) is covered in multiple layers with fire-resistant members x2 (see FIG. 7).

[0051] Therefore, according to the storage section installation structure C shown in FIG. 7 and the manufacturing method thereof, substantially the same effects as those of the storage section installation structures A and B are achieved. In addition, the fixed base 50 is located between the upper and lower horizontal frame members 32, 32, which are less susceptible to the effects of flames. Therefore, even in the unlikely event of a fire breaking out, deterioration of the fixed base 50 due to the effects of heat can be reduced.

[0052] <Fourth embodiment> The opening and closing device shown in FIG. 9 is obtained by replacing the storage unit installation structure A in the opening and closing device 1 with a storage unit installation structure D. The storage unit installation structure D is the same as the storage unit installation structure A except that the fire-resistant members x2, x2 between the core material 50a and the wooden base x1 are omitted, and the core material 50a is in direct contact with the wooden base x1.

[0053] That is, in the process of constructing the wooden skeleton X in this storage unit installation structure D, the core material 50a is fastened to the vertical surface of the wooden base x1 by the fasteners 38. Then, the wooden base x1 and the core material 50a are covered in multiple layers with the fire-resistant member x2.

[0054] In this way, the wall surface Xa is formed with a fixed base portion 50 that is continuously formed in the width direction and protrudes toward the front side (left side in FIG. 9) and has a generally horizontally convex shape in vertical cross section. The support 30 is received on the fixed base 50 and is fastened to the wooden base x1 by the fasteners 38.

[0055] Therefore, according to the storage section installation structure B and the manufacturing method thereof shown in FIG. 9, substantially the same effects as those of the storage section installation structure C described above are achieved.

[0056] <Other Modifications> According to the above embodiment, any one of the multiple horizontal frame members 32 in the support body 30 is supported by the fixed base 50, but as another example, two or more or all of the multiple horizontal frame members 32 may be supported by the fixed base 50. For example, in the embodiment shown in FIG. 10, the upper and lower horizontal frame members 32 of the support body 30 are each supported by a plurality of fixed bases 50, thereby further improving the installation strength of the support body 30.

[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.
