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 increases the weight of the storage section, and there is a risk that the strength of the fastening portion of the support 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 / 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 on the side of the support body, the support body and the fixed base being connected to each other. Effect of the Invention

[0006] Since the present invention is configured as described above, the strength of the fastening portion of the support can be supplemented by the fixing base. [Brief description of the drawings]

[Figure 9] FIG. 11 is a front view showing another example of the support body and the fixed support part. 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 is fixed to a wall surface Xa of a wooden structure X above an opening so as to open and close the opening of the wooden structure X using 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 includes a support body 30 that supports the storage unit 20, and a fixed base 50 that is fixed to a wooden structure X, and connects the support body 30 and the fixed base 50 (see Figs. 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 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 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).

[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 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.

[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 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.

[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 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 their center, and a protruding portion 31 protruding upward from the center of the upper horizontal frame member 32. The upper rear end side 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 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.).

[0027] 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 a connecting member 33 (see FIG. 3). 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.

[0028] One end and the other end of the horizontal frame member 32 protrude outward in the width direction beyond the connecting member 33 , and this protruding portion is received by the upper end of the fixed base 50 .

[0029] 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.) (see FIG. 2), and is supported by a fixed base 50 from below.

[0030] The fixed base 50 is formed in a generally rectangular shape that is continuous in the vertical direction, with its upper end contacting the lower surface of the upper horizontal frame member 32 to support the support body 30 from below. Furthermore, the fixed base 50 has an inner surface in the width direction that contacts the side surface of the connecting member 33 of the support body 30 (see FIG. 3).

[0031] This fixed base 50 is integrally constructed by a rectangular columnar core material 50a extending vertically and fire-resistant members x2, x2 (see Figure 5) covering the entire outer surface of this core material 50a in a multi-layered manner, and is connected to the support 30 by vertical and horizontal fasteners 51, 52 (e.g., screws, bolts, anchor members, nails, etc.) (see Figure 3).

[0032] The core material 50a is a piece of wood that extends in the vertical direction of the support body 30, and is fastened to the wooden structure X by one or more fasteners 53 (e.g., screws, bolts, anchor members, nails, etc.). The fasteners 53 penetrate the core material 50a from the front side to the rear side (to the right in FIG. 2) and are fastened to the wooden structure X.

[0033] The fire-resistant members x2 cover the four 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).

[0034] The vertical fasteners 51 penetrate the upper horizontal frame member 32 from top to bottom, and then penetrate the fire-resistant members x2, x2, and are fastened to the core material 50a (see FIG. 4).

[0035] The lateral fastener 52 penetrates the connecting material 33 from the inside to the outside in the width direction, and further penetrates the fire-resistant members x2, x2, and is fastened to the core material 50a (see FIG. 5). The fastener 52 is subjected to a shear force due to the weight of the support body 30 and the storage section 20, etc. That is, if fastener 52 is used in the pulling direction, fastener 52 is subject to a force in the removal direction, but with fastener 52 of the above configuration, force in the removal direction is less likely to act, which is advantageous in terms of strength.

[0036] <Example of manufacturing method> Next, features of the manufacturing method of the storage section installation structure A will be described. FIG. 6 shows a procedure for fixing the support body 30 to the wooden structure X as a preliminary step before the storage unit 20 is installed on the wooden structure X.

[0037] First, two fixed bases 50, 50 are fixed to the wall surface Xa of a wooden structure X at predetermined positions with a space between them on the left and right. Each fixed base 50 is fastened to the wall surface Xa by a plurality of fasteners 53 that are inserted from the front side to the back side.

[0038] Next, as shown in FIG. 6( a ), the end sides in the width direction of the support bodies 30 (specifically, the horizontal frame members 32 ) are placed on the upper ends of the respective fixed bases 50 . As shown in FIG. 6(b), the support body 30 and the fixed base 50 are integrally connected by a fastener 51 inserted from above and a fastener 52 inserted from the inside in the width direction.

[0039] The support 30 is also fastened to the wall surface Xa by fasteners 38 (see FIG. 2).

[0040] <Another example of manufacturing method> FIG. 7 shows a procedure in which the storage unit 20 is first installed on the wooden frame X, and then the fixed base 50 is provided to reinforce the storage unit 20. The storage section 20 is fastened to a wall surface Xa of the wooden structure X by fasteners 38 (see FIG. 2).

[0041] As shown in FIG. 7(a), a fixed base 50 is attached to the storage section 20 fixed as described above. More specifically, the fixed base 50 is fitted into a recessed corner portion where the side surface of the connecting member 33 of the support body 30 and the lower surface of the end side of the horizontal frame member 32 intersect. Thereafter, as shown in FIG. 7(b), the fixed base 50 is integrally connected to the support 30 by a fastener 51 inserted from above and a fastener 52 inserted from the inside in the width direction.

[0042] 1 to 7 and the manufacturing method thereof, the strength of the fastening portion of the support body 30 can be supplemented by the fixed base 50. In other words, the support body 30 can be reinforced by the fixed base 50. In addition, it is possible to prevent the fastening points of the support 30 from deteriorating due to the effects of heat during a fire, etc., and causing the support 30 to fall off.

[0043] <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 a partial modification of the storage unit installation structure A described above, so the modified parts will be mainly described in detail, and the same reference numerals will be used for parts that function in the same way as the storage unit installation structure A described above.

[0044] FIG. 8 is a front view of the support body 30' and the fixed base 50' which constitute the storage section installation structure B. As shown in FIG.

[0045] The support body 30' is obtained by replacing the lower horizontal frame member 35 of the support body 30 described above with a horizontal frame member 35' and by replacing each of the connecting members 33 with connecting members 33'.

[0046] The lower horizontal frame member 35' is a long steel member having approximately the same length as the upper horizontal frame member 32. This horizontal frame member 35' can be a common part with the horizontal frame member 32.

[0047] The upper horizontal frame member 32 and the lower horizontal frame member 35' are disposed generally parallel to each other at a predetermined interval in the vertical direction. One end side and the other end side of the horizontal frame member 32 and the horizontal frame member 35' in the width direction are integrally connected by a connecting member 33' while securing a space that is U-shaped when viewed from the front, into which the fixed base 50' can be inserted from the outside in the width direction (see FIG. 8). In other words, the end side in the width direction of the support body 30' is configured in a U-shape from the front consisting of one end side of the upper horizontal frame member 32, a connecting member 33' extending in the vertical direction, and a lower horizontal frame member 35', and the fixed base 50' is fitted into the concave portion.

[0048] The fixed base 50' is a member having the same configuration as the fixed base 50 but a different length. The length of this fixed base 50' in the vertical direction is set so as to fit between the horizontal frame member 32 and the horizontal frame member 35'.

[0049] The manufacturing procedure for the storage unit installation structure B is substantially the same as that for the storage unit installation structure A, and either the support body 30' or the fixed base 50' may be fixed first.

[0050] That is, as an example, the fixed base 50' is first fixed to the wooden structure X, and then the support 30' is fitted into the fixed base 50' from the front side to the back side. Then, the connecting member 33' and the fixed base 50' are connected with fasteners 52 in the left-right direction, and the upper horizontal frame member 32 and the fixed base 50' are also connected with fasteners 51 in the up-down direction. The support 30' is also fixed to the wooden structure X.

[0051] As another example, the support 30' is first fixed to the wooden structure, and then the fixed base 50' is fitted to the support 30' from the side or front. After this, the connecting member 33' and the fixed base 50' are connected with fasteners 52 in the left-right direction, and the upper horizontal frame member 32 and the fixed base 50' are also connected with fasteners 51 in the up-down direction. The fixed base 50' is also fixed to the wooden structure X.

[0052] Therefore, according to the storage section installation structure B shown in FIG. 8, similarly to the storage section installation structure A, the strength of the fastening portion of the support body 30' can be supplemented by the fixed base 50'.

[0053] <Third embodiment> The storage unit installation structure B shown in Figure 8 is the same as the storage unit installation structure A described above, except that the vertical fasteners 51 are omitted, and the horizontal frame material 32 and the fixed base 50 are in contact with each other or in close proximity with a gap s between them.

[0054] According to this storage section installation structure B, similarly to the storage section installation structure A, the strength of the fastening portion of the support body 30 can be supplemented by the fixed base 50 connected to the connecting material 33 by the fastener 52. Furthermore, the vertical position and gap s of the support 30 relative to the fixed base 50 can be adjusted as appropriate.

[0055] <Other Modifications> According to the above embodiment, the core material 50a of the fixed bases 50, 50' is made of wood, which is particularly favorable for workability, but the core material 50a may also be made of a hard material other than wood, such as metal.

[0056] 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.

[0057] <Summary> As described above, the above embodiments disclose the following inventions. (1) A storage unit installation structure in which a storage unit for storing an opening / 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 on the side of the support body, the support body and the fixed base being connected to each other.
