[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-211257 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, large building structures have been constructed from wood, and large shutter devices such as heavy shutters are sometimes installed on these wooden structures. In such cases, relatively heavy guide rails are fastened to the wooden structure with fasteners such as screws. However, in conventional fasteners, screws or other fasteners are threaded horizontally onto the surface of the building, which leaves room for improvement as they may come loose under strong external forces.In addition, in the unlikely event of a fire, heat from the fire is transferred to the fastener, causing thermal deterioration of the fastening part of the fastener, which may result in the fastener loosening or falling off.

[0005] An object of the present invention is to provide an installation structure and construction method for firmly fixing components that make up a switchgear to an installation surface and for stably and reliably installing the switchgear. [Means for solving the problem]

[0006] In view of the above problems, one aspect of the present invention is provided with the following configuration. an attachment member having a base portion placed on the installation surface and having a base portion mounting hole through which a screw shank of a first fastener is inserted, and a wall portion erected substantially vertically from the periphery of the base portion and having a screw hole into which the screw shank of a second fastener is threaded; the first fastener having a screw shank portion with a thread that can be threaded into the installation surface and a head provided at the rear end of the screw shank; and the second fastener having a screw shank portion with a thread that can be threaded into the screw hole in the wall portion and a head provided at the rear end of the screw shank, wherein the base portion of the attachment member is fastened to the installation surface by the first fastener, and a lower part of the component is fastened to the wall portion of the attachment member by the second fastener.

[0008] (Embodiment) Hereinafter, an embodiment of the present invention will be described. In this specification, the term "opening / closing body width direction" 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 (the left-right direction in FIGS. 1 and 2). Furthermore, the "outward direction" in the "opening / closing body width direction" refers to a direction away from the opening / closing body 10 (the direction toward the right for the guide rail 30 on the right side in FIG. 1, and the direction toward the left for the guide rail 30 on the left side). Furthermore, the "inward direction" in the "opening / closing body width direction" refers to a direction toward the opening / closing body 10 (the direction toward the left for the guide rail 30 on the right side in FIG. 1, and the direction toward the right for the guide rail 30 on the left side).

[0009] Additionally, "thickness direction of the opening / closing body" refers to the thickness direction of the opening / closing body (the up-and-down direction in FIG. 2(a)). Additionally, "outward direction" in "thickness direction of the opening / closing body" refers to the direction away from the opening / closing body 10, and "inward direction" in "thickness direction of the opening / closing body" refers to the direction toward the opening / closing body 10.

[0010] (Overall configuration of the switchgear) First, the overall configuration of a switching device 1 according to the present invention will be described. Fig. 1 is a schematic front view showing a switching device to which an installation structure for a switching device according to the present invention is applied.

[0011] As shown in Figure 1, the opening and closing device 1 is installed, for example, on a wooden base that forms the skeleton of a building, and includes an opening and closing body 10 that opens and closes an opening in the building, a storage section 20 that extends the opening and closing body 10 in the closing direction and stores it in the opening direction, and a guide rail 30 and a center pillar 40 that guide the opening and closing body 10 in the closing and opening directions.

[0012] In this embodiment, the opening / closing body 10 consists of left and right opening / closing bodies 10A and 10B arranged side by side in the width direction of the opening / closing body, and one opening / closing body 10A is configured to open and close between one guide rail 30 and the center post 40, and the other opening / closing body 10B is configured to open and close between the other guide rail 30 and the center post 40.

[0013] Each of the opening / closing bodies 10A, 10B is configured by connecting a plurality of slats 10A1, 10B1, each of which is formed by bending a horizontally elongated, generally rectangular metal plate, so that the slats can rotate vertically. Other examples of the opening / closing body 10 include a configuration consisting of a plurality of panels, a configuration in which a plurality of pipes are arranged at intervals vertically, and a configuration in which slats, panels, pipes, etc. are appropriately combined.

[0014] The storage section 20 is composed of a winding shaft 21 that winds and unwinds the opening / closing body 10, a support bracket 22 that supports the winding shaft 21 at both ends, an opening / closing machine 23 that is a driving source that drives and rotates the winding shaft, and a cover member 25 that covers the winding shaft 21, etc.

[0015] The winding shaft 21 is made up of left and right winding shafts 21A, 21B that wind and unwind the opening-closing bodies 10A, 10B, respectively. Each winding shaft 21A, 21B is configured in the shape of a long cylinder extending in the width direction of the opening-closing body, and each end is rotatably supported by a respective support bracket 22. Each winding shaft 21A, 21B is configured in such a way that the winding body is rotatably supported on the outer periphery of a non-rotatable fixed shaft via a bearing, or in such a way that a shaft portion integral with the winding body is rotatably supported on the support bracket 22 via a bearing.

[0016] The support bracket 22 is formed, for example, by appropriately processing (for example, by pressing or bending) a metal plate, and is integrally formed with, for example, a rectangular plate-shaped mounting piece (not shown) that is fastened and fixed along the vertical surface of the wooden body with fasteners such as screws, and a support body (not shown) that protrudes from the fastening piece away from the vertical surface of the wooden body and supports each end of each winding shaft 21A, 21B.

[0017] The opening and closing devices 23 are made up of opening and closing devices 23A, 23B that respectively open and close the opening and closing bodies 10A, 10B, and are configured, for example, with electric motors and gears that are controlled to rotate forward, reverse, stop, increase or decrease the rotation speed, etc. Each opening and closing device 23A, 23B is supported by axle support brackets 22 arranged on the left and right guide rails 30 side, and their rotational force is transmitted to each winding shaft 21A, 21B by power transmission means (not shown) such as a chain and sprocket.

[0018] The opening and closing devices 23A, 23B are independently controlled, so that the two adjacent winding shafts 21A, 21B are operated independently or in conjunction with each other. When the two winding shafts 21A and 21B are to be operated in conjunction with each other, for example, the opening and closing devices 23A and 23B may be controlled so as to rotate approximately synchronously.

[0019] In the opening and closing device 1, the operation of each opening and closing machine 23A, 23B drives each winding shaft 21A, 21B forward and reverse, and both side ends of each opening and closing body 10A, 10B rise and fall while being guided by the guide rail 30 and the center pillar 40 to open and close the opening.

[0020] The cover member 25 is configured to cover the periphery of the winding shaft 21 and the opening-closing body 10 wound around the winding shaft 21. The cover member 25 is formed in an elongated shape, for example, with a substantially U-shaped or arc-shaped vertical cross section that continues in the opening / closing width direction, and is arranged to cover the periphery of the winding shaft 21 and the opening-closing body 10 wound around the winding shaft 21.

[0021] As shown in FIG. 1, the guide rail 30 guides the non-adjacent side edges of the left and right opening / closing bodies 10A, 10B in the opening / closing direction (vertical direction) so that they can move. The guide rail 30 is disposed between the storage section 20 and the installation surface X (e.g., the floor, the ground, a frame member, etc.), and is fixed immovably to immovable parts within the storage section 20 and the installation surface X. The specific configuration of the guide rail 30 and its installation structure will be described later.

[0022] The center pillar 40 is disposed between the opening / closing bodies 10A, 10B arranged adjacent to each other on the left and right, and guides the adjacent side edges of each opening / closing body 10A, 10B to move in the opening / closing direction (up and down direction).It is disposed between the storage section 20 and the installation surface X (e.g., floor, ground, frame member, etc.), and is fixed immovably to an immovable part within the storage section 20 and the installation surface X. The specific configuration of the center pillar 40 and its installation structure will be described later.

[0023] (Guide rail configuration) Next, a description will be given of an example of a specific configuration of the guide rail 30. Fig. 2 is a schematic diagram of a guide rail to which the installation structure of the opening and closing device according to the present invention is applied, Fig. 2(a) is a schematic plan view of the guide rail, and Fig. 2(b) is a schematic side view of the guide rail.

[0024] The guide rail 30, which is a component of the opening / closing device 1, has a guide portion 30A that vertically guides the side edge of the opening / closing body 10 in the opening / closing body width direction, and a hollow portion 30B that forms a hollow space that is continuous in the vertical direction. This guide rail 30 is formed from a metal material such as steel, stainless steel, or aluminum alloy, and, as shown in Fig. 2, for example, can be configured by integrating an elongated first member 31 that functions as the guide portion 30A with an elongated second member 35 that reinforces and supports the first member 31 from the outside in the opening / closing body width direction and forms the hollow portion 30B between itself and the first member 31.

[0025] The first member 31 has, for example, a U-shaped portion 32 whose cross-sectional shape is formed in an approximately U-shape that opens toward the inside of the opening / closing body in the width direction, and a pair of L-shaped portions 33 each formed in an approximately L-shape that are connected to the opening ends of this U-shaped portion 32.

[0026] The U-shaped portion 32 extends in the width direction of the opening / closing body and has a pair of plate-like guide wall portions 32a arranged opposite each other with a predetermined gap therebetween, and a plate-like first bottom wall portion 32b extending in the thickness direction of the opening / closing body and connected to each outer edge of the guide wall portions 32a in the width direction of the opening / closing body. This U-shaped portion 32 functions as a guide portion 30A into which one end of the opening / closing body 10 in the width direction of the opening / closing body is inserted, guiding the opening / closing body 10 in the closing direction and the opening direction.

[0027] The L-shaped portion 33 has a plate-shaped front wall portion 33a extending in the thickness direction of the opening / closing body, and a plate-shaped piece portion 33b extending outward in the width direction of the opening / closing body and connected approximately perpendicular to the outer edge of the front wall portion 33a in the thickness direction of the opening / closing body. The lower part of the front wall 33a is provided with a guide rail mounting hole 33a1 which can communicate with a side wall mounting hole 53a formed in one of the side walls 53 of the guide rail fixing bracket 50 (see Figure 3) described later, and through which the screw shaft M2a of the second fastener M2 can be inserted. This guide rail attachment hole 33a1 can be formed as, for example, a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for screwing onto the screw shank M2a of the second fastener M2.

[0028] The U-shaped portion 32 and the pair of L-shaped portions 33 are integrally formed by, for example, bending a metal plate material or by welding each portion.

[0029] The second member 35 has, for example, a generally U-shaped cross section that opens toward the inside in the width direction of the opening / closing body, and includes a pair of second side wall portions 37, 37 that extend in the width direction of the opening / closing body and are arranged opposite each other with a predetermined gap between them, and a plate-shaped second bottom wall portion 36 that extends in the thickness direction of the opening / closing body and is connected to each outer edge of the second side wall portions 37, 37 in the width direction of the opening / closing body. The second member 35 is integrally formed, for example, by bending a metal flat plate or by welding each portion.

[0030] A guide rail mounting hole 37a is formed at the bottom of each second side wall portion 37, 37 of the guide rail 30, which can communicate with the front wall mounting hole 52a formed in the front wall portion 52 of the guide rail fixing bracket 50 (see Figure 3) described later, and is for inserting the screw shaft portion M2a of the second fastener M2. In addition, a guide rail mounting hole 36a is formed in the lower part of the second bottom wall portion 36 of the guide rail 30, which is capable of communicating with a side wall mounting hole 53a formed in the other side wall portion 53 of the guide rail fixing bracket 50 (see Figure 3) described later, and for inserting the screw shaft portion M2a of the second fastener M2. These guide rail mounting holes 36a, 37a can be formed as, for example, screw holes (specifically, female screw holes or pilot holes for tapping screws) for threaded engagement with the screw shank M2a of the second fastener M2.

[0031] The second member 35 is joined to the first member 31 and functions as a reinforcing portion that reinforces the first member 31, and also forms a hollow portion 30B that forms a hollow space between the second member 35 and the first member 31.

[0032] The first member 31 and the second member 35 are integrated by being fixed together using a fixing means such as welding. Specifically, with the first bottom wall portion 32b of the first member 31 abutting against the inner surface of the second bottom wall portion 36 of the second member 35 and with a portion of each piece portion 33b of the first member 31 overlapping a portion of each second side wall portion 37, 37 of the second member 35, the piece portion 33b and the second side wall portions 37, 37 can be joined together using a fixing means such as welding to form an integrated unit. In the illustrated example, the guide rail 30 has two independent hollow portions 30B defined by a first member 31 and a second member 35.

[0033] Also, as shown in Figure 2(b), the lower end of the second member 35 is located at a higher position (height h) than the lower end of the first member 31, and an opening area 30C is formed to expose to the outside the working hole 52b formed in the front wall portion 52 of the guide rail fixing bracket 50 (see Figure 3(c)) described later when the guide rail 30 is installed. The opening region 30C may be formed by, for example, cutting out a portion of the second side wall portions 37, 37 of the second member 35 or by forming a through opening.

[0034] (Guide rail installation structure) Next, an example of an installation structure for a guide rail 30 according to the present invention will be described. Fig. 3 is a schematic diagram showing an example of a guide rail fixing bracket for a guide rail installation structure according to the present invention, and Figs. 4 to 7 are explanatory diagrams illustrating an installation structure for a guide rail using the same guide rail fixing bracket.

[0035] <Guide rail fixing bracket> The lower part of the guide rail 30 is fixed immovably to an installation surface X such as a floor or the ground by a guide rail fixing bracket 50 serving as an attachment member. This guide rail fixing bracket 50 has a plate-shaped base plate 51 placed and fixed on the installation surface X, a plate-shaped front wall 52 extending upward substantially vertically from one end edge of the base plate 51 in the thickness direction of the opening / closing body, and plate-shaped side wall portions 53, 53 extending upward substantially vertically from both end edges of the base plate 51 in the width direction of the opening / closing body. The guide rail fixing metal fitting 50 is formed integrally by, for example, bending a metal plate material or welding each portion together.

[0036] [Board] The base plate portion 51 forms a portion that is placed on (abuts against) and fixed to the installation surface X, and has a base plate attachment hole 51a (insertion hole) formed in approximately the center thereof for inserting the first fastener M1 (see FIG. 4). As shown in FIG. 4(b), this base plate attachment hole 51a is formed to have a diameter D2 larger than the maximum diameter D1 of the screw shank M1a of the first fastener M1 (D2>D1), that is, it is formed as a through hole (so-called loose hole) for inserting the screw shank M1a of the fastener M1 with a predetermined adjustment allowance (gap=D2-D1).

[0037] [Front wall] The front wall 52 is formed in the shape of a plate extending upward substantially vertically from one edge of the base plate 51 in the thickness direction of the opening / closing body, and is provided in its approximately central portion in the vertical and horizontal directions with a front wall mounting hole 52a for inserting a screw shank M2a of a second fastener M2 (see FIG. 5) made of, for example, a screw or bolt. The front wall mounting hole 52a is formed, for example, as a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for threading onto the screw shank M2a of the second fastener M2.

[0038] In addition, a working hole 52b, for example, having a substantially rectangular shape, is formed through the front wall portion 52, and the head M1b of the first fastening device M1 can be rotated using a tool T (see FIG. 6) through this working hole 52b.

[0039] The height of the working hole 52b is greater than the height of the head M1b (in a temporarily fixed state) of the first fastener M1. Therefore, even if the first fastener M1 is in a slightly loose state, the tool T inserted into the working hole 52b can engage with the head M1b of the first fastener M1.

[0040] Furthermore, since the positions of the front wall mounting hole 52a and the side wall mounting hole 53a are higher than the working hole 52b, even when the first fastener M1 is in a pre-tightened state where it is not fully tightened, the screw shaft M2a of the second fastener M2 does not interfere with the head M1b of the first fastener M1.

[0041] In addition, it is preferable that the width of the working hole 52b is such that, when the head M1b of the first fastener M1 is a hexagonal head (or a hexagonal hole corresponding to a hexagonal wrench), the first fastener M1 can be rotated by more than 60 degrees around its axis using a tool T.

[0042] The shape and size of the working hole 52b are not limited to the above example, and can be formed into any shape and size as long as the head M1b of the first fastener M1 can be rotated using the tool T.

[0043] [Side wall] The side walls 53, 53 are formed in the shape of plates extending substantially vertically upward from both end edges of the base plate 51 in the width direction of the opening / closing body, and are provided with a side wall mounting hole 53a at their approximately central portions in the vertical and horizontal directions for inserting a screw shank M2a of a second fastener M2 (see FIG. 6) made of, for example, a screw or bolt. The side wall mounting hole 53a can be formed, for example, as a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for threading onto the screw shank M2a of the second fastener M2.

[0044] <1st fastener> The first fastener M1 is a fastener for attaching and fixing the base plate portion 51 of the guide rail fixing bracket 50 to the installation surface X, and has a screw shaft portion M1a with a screw portion that is inserted through the base plate mounting hole 51a of the base plate portion 51 and screwed into the installation surface X, and a head portion M1b provided at the rear end of the screw shaft portion M1a.

[0045] The first fastener M1 can be, for example, a screw having a hexagonal head and a screw shank, such as a coach screw. While the present embodiment describes an example in which the head M1b of the first fastener M1 is a hexagonal head, the configuration of the head M1b is not limited to this. For example, the head of the first fastener may be configured to have a hexagonal hole, or to have a hexagonal head with a hexagonal hole at the top.

[0046] <Tools> Tool T (see FIG. 6) is a tool for rotating head M1b of first fastener M1. For example, if head M1b of first fastener M1 is a hexagonal head, tool T may be a wrench or box wrench that fits into head M1b of first fastener M1. Note that if the head of the first fastener M1 is configured to have a hexagonal hole, tool T may be a hexagonal wrench that fits into the hexagonal hole.

[0047] When installing and fixing the guide rail 30 on the installation surface X, this tool T can be used to rotate the head M1b of the first fastening device M1 through a through-hole 52b formed in the front wall 52 of the guide rail fixing bracket 50.

[0048] <Second fastener> The second fastener M2 (see FIG. 5) is used to attach and fix the guide rail 30 to the guide rail fixing bracket 50, and is composed of a fastener having a screw shank M2a and a head M2b, which may be made of, for example, a screw or a bolt. This second fastener M2 can attach and fix the guide rail 30 to the guide rail fixing bracket 50 by screwing into each of the mounting holes 33a1, 36a, 37a formed in the guide rail 30 and each of the mounting holes 52a, 53a formed in the guide rail fixing bracket 50 that communicate with these mounting holes 33a1, 36a, 37a. The second fastener M2 is rotated using a known tool (such as a screwdriver or hexagonal wrench) that can engage with and rotate the head M2b.

[0049] (Guide rail installation process) Next, an example of the installation process for installing the lower part of the guide rail 30 on an installation surface X such as a floor or the ground will be described with reference to Figures 4 to 7. Figure 4 shows a state in which the guide rail fixing bracket is temporarily fixed to the installation surface, Figure 5 shows a state in which the guide rail is installed relative to the temporarily fixed guide rail fixing bracket, Figure 6 shows a state in which the temporarily fixed guide rail fixing bracket is fixed immovably to the installation surface, and Figure 7 shows a state in which the guide rail is fixed immovably to the installation surface via the guide rail fixing bracket.

[0050] [Process 1] First, as shown in Fig. 4, the guide rail fixing bracket 50 is placed on the installation surface X of the guide rail 30. In this embodiment, the guide rail 30 has two hollow portions 30B (see Fig. 2) along the thickness direction of the opening / closing body, so as shown in Fig. 4(a), each guide rail fixing bracket 50 is placed on the installation surface X so as to correspond to each hollow portion 30B.

[0051] Next, the screw shaft portion M1a of the first fastener M1 is inserted into the board mounting hole 51a formed in the board portion 51 and screwed into the installation surface X to temporarily fasten (temporarily fix) the guide rail fixing bracket 50 onto the installation surface X.

[0052] In this provisionally fastened state (provisionally fixed state), the head M1b of the first fastener M1 is provisionally fastened so as to reach a position facing the working hole 52b formed in the front wall portion 52 of the guide rail fixing metal fitting 50. Furthermore, in this provisionally fastened state, the screw shaft portion M1a of the first fastener M1 is loosely fitted into the board mounting hole 51a with an adjustment allowance (gap = D2-D1), so that the installation position of the guide rail fixing bracket 50 relative to the installation surface X can be fine-tuned within this adjustment allowance.

[0053] In this step 1, the guide rail 30 is not positioned above the guide rail fixing bracket 50, and an open work space exists, so that the temporary tightening work of the first fastening device M1 can be performed in this work space without inserting and operating the tool T into the work hole 52b of the guide rail fixing bracket 50.

[0054] [Process 2] Next, as shown in Figure 5, the guide rail 30 is placed upright in the vertical direction, with its lower part fitted onto the temporarily fixed guide rail fixing bracket 50, and the guide rail fixing bracket 50 and the guide rail 30 are fixed together with the second fastener M2.

[0055] Specifically, the screw shaft portion M2a of the second fastener M2 is screwed into the mounting hole 33a1 formed in the lower part of each front wall portion 33a of the guide rail 30 and the mounting hole 53a formed in the side wall portion 53 of the guide rail fixing bracket 50 to fasten the second fastener M2, and the screw shaft portion M2a of the second fastener M2 is screwed into the mounting hole 37a formed in the lower part of the second side wall portions 37, 37 of the guide rail 30 and the mounting hole 52a formed in the front wall portion 52 of the guide rail fixing bracket 50 to fasten the second fastener M2.

[0056] By this step 2, the guide rail 30 and the guide rail fixing metal fitting 50 are in an integrated state and temporarily installed on the installation surface X. In other words, the guide rail 30 integrated with the guide rail fixing metal fitting 50 is temporarily installed on the installation surface X in a state that allows fine adjustment within the adjustment margin of the guide rail fixing metal fitting 50.

[0057] [Process 3] Next, the installation position of the guide rail 30 temporarily installed on the installation surface X is adjusted (fine-tuned within the adjustment allowance) to the specified installation position, and then the first fastening device M1 is fully tightened to immobilize the guide rail 30 relative to the installation surface X. Specifically, as shown in Fig. 6, the tool T is inserted into the working hole 52b formed in the front wall 52 of the guide rail fixing metal fitting 50, and the head M1b of the first fastener M1 is rotated to perform final fastening. As a result, the lower part of the guide rail 30 is stably and immovably fixed to the installation surface X by the guide rail fixing metal fitting 50, as shown in Fig. 7.

[0058] As described above, according to the guide rail installation structure of the present invention, the guide rail 30 can be easily and stably installed on the installation surface X, and therefore the installation efficiency of the guide rail 30 is improved.

[0059] Next, a description will be given of a specific configuration of the center pillar 40 and an example of an installation structure for the center pillar 40. Fig. 8 is a schematic plan view of a center pillar to which the installation structure for a switching device according to the present invention is applied.

[0060] (Structure of the center pillar) 8, the center post 40, which is a component of the opening and closing device 1, has a guide portion 40A that vertically guides the end portion of the opening and closing body 10 in the opening and closing body width direction, and a plurality of hollow portions 40B that form hollow spaces that are continuous in the vertical direction. Note that these plurality of hollow portions 40B are configured to communicate with each other at the bottom of the center post 40 to form one hollow portion (space portion), the specific configuration of which will be described later.

[0061] The center pillar 40 is formed from a metal material such as steel, stainless steel, aluminum alloy, etc., and has a shape similar to two guide rails 30 joined back to back, as shown in Figure 8, and is configured so that one side edge in the width direction of one opening / closing body 10A is surrounded by a guide portion 40A with a generally concave cross section at one end side in the width direction of the opening / closing body, and one side edge in the width direction of the other opening / closing body 10B is surrounded by a guide portion 40A with a generally concave cross section at the other end side.

[0062] This center pillar 40 has, for example, a pair of elongated first pillar members 41 extending in the vertical direction, a pair of elongated second pillar members 42 extending in the vertical direction, and a pair of elongated third pillar members 43 extending in the vertical direction, and these pillar members 41, 42, 43 can be joined together by a joining means such as welding to form an integrated structure.

[0063] The first pillar member 41 has, for example, a first U-shaped portion 41a whose cross-sectional shape is formed in an approximately U-shape that opens inward in the thickness direction of the opening / closing body, and a pair of first arm portions 41b that extend inward in the width direction of the opening / closing body and are connected approximately perpendicular to the opening edge of this first U-shaped portion 41a.

[0064] The first U-shaped portion 41a has a first front wall 41a1 extending in the width direction of the opening / closing body, and a pair of first side walls 41a2 extending inward in the width direction of the opening / closing body and connected to the end edge of the first front wall 41a1 in the width direction of the opening / closing body generally perpendicular to the opening / closing body. The first front wall 41a1 of the first U-shaped portion 41a has an opening region 40C (see FIG. 10) that exposes the working hole 62b formed in the front wall 62 of the center post fixing bracket 60 to the outside when the center post 40 is installed. This first pillar member 41 is formed integrally by, for example, bending a metal flat plate material or welding each portion together.

[0065] The second pillar member 42 has, for example, a second U-shaped portion 42a whose cross-sectional shape is formed in an approximately U-shape that opens in the thickness direction of the opening / closing body, and a pair of second arm portions 42b that extend outward in the thickness direction of the opening / closing body and are connected approximately perpendicular to the opening edge of this second U-shaped portion 42a. In addition, the second U-shaped portion 42a has a second bottom wall portion 42a1 extending in the thickness direction of the opening / closing body, and a pair of second guide wall portions 42a2 extending in the width direction of the opening / closing body and connected approximately perpendicular to the thickness direction edge of this second bottom wall portion 42a1. The second pillar member 42 is formed integrally by, for example, bending a metal plate material or welding each portion.

[0066] The third pillar member 43 has, for example, a cross-sectional shape that is approximately U-shaped and opens in the width direction of the opening / closing body, and has a third bottom wall portion 43a that extends in the thickness direction of the opening / closing body, and a pair of third arm portions 43b that extend in the width direction of the opening / closing body and are connected approximately perpendicular to the thickness direction edge of the third bottom wall portion 43a of the opening / closing body, and functions as a reinforcing portion that reinforces the center pillar 40 from its inside. This third pillar member 43 is formed integrally by, for example, bending a metal flat plate material or welding each portion.

[0067] Furthermore, the lower end of the third pillar member 43 is located at a position higher than the lower ends of the first pillar member 41 and the second pillar member 42 (position H2 in FIG. 10(c)), and is located at a position higher than the height H1 of the front wall portion 62 of the center pillar fixing bracket 60, which will be described later. As a result, the multiple hollow portions 40B are connected at the bottom of the center pillar 40 to form a single hollow portion (space portion), and the center pillar fixing bracket 60 can be placed in this single hollow portion (space portion).

[0068] Furthermore, each of the first pillar members 41 and each of the second pillar members 42 that make up the center pillar 40 is formed with a center pillar mounting hole (not shown) that can communicate with a plurality of mounting holes 62a, 63a formed in a center pillar fixing bracket 60 (see FIG. 9) described below and through which the screw shank M2a of the second fastener M2 is inserted. This center pillar mounting hole is formed, for example, as a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for threading onto the screw shank M2a of the second fastener M2.

[0069] (Center column installation structure) Next, an example of an installation structure for the center pillar 40 according to the present invention will be described. Fig. 9 is a schematic diagram showing an example of a center pillar fixing bracket for this installation structure, and Fig. 10 is an explanatory diagram illustrating an installation structure for the center pillar using this center pillar fixing bracket.

[0070] <Middle pillar fixing bracket> The lower part of the center pillar 40 is fixed immovably to an installation surface X such as a floor or the ground by a center pillar fixing bracket 60 serving as an attachment member. This center pillar fixing bracket 60 has a plate-shaped base plate portion 61 placed and fixed on the installation surface X, plate-shaped front wall portions 62 extending upward substantially vertically from each edge of the base plate portion 61 in the thickness direction of the opening / closing body, and plate-shaped side wall portions 63 extending upward substantially vertically from both end edges of the base plate portion 61 in the width direction of the opening / closing body. This center pillar fixing metal fitting 60 is formed integrally, for example, by bending a flat metal plate and welding each portion together.

[0071] [Board] The base plate 61 forms a portion that is fixed by contacting the installation surface X, and is formed in a generally H-shape in plan view, with a pair of long sides 61a that extend in the width direction of the opening / closing body and are arranged opposite each other, and short sides 61b that are located approximately in the center of each long side 61a and connect the long sides 61a. In other words, the base plate 61 is formed in a shape that corresponds to the cross-sectional shape of the center pillar 40 and can be placed in a hollow portion that is formed in communication with the lower interior of the center pillar 40.

[0072] A plurality of board mounting holes 61a1 (three in the illustrated example) are formed in each longitudinal portion 61a of the board portion 61 at predetermined intervals in the width direction of the opening / closing body. These board mounting holes 61a1 (insertion holes) are through holes for inserting the first fastener M1 (see FIG. 10(c)), and are formed with a diameter D2 larger than the maximum diameter D1 of the screw shank M1a of the first fastener M1 (D2>D1). In other words, they are formed as through holes (so-called loose holes) with a predetermined adjustment allowance (gap = D2-D1) for inserting the screw shank M1a of the fastener M1.

[0073] [Front wall] The front wall 62 is formed in the shape of a plate extending upward substantially vertically from each edge of the base plate 61 in the thickness direction of the opening / closing body, and has a plurality of front wall mounting holes 62a (three in the illustrated example) formed at predetermined intervals in the width direction of the opening / closing body. These front wall mounting holes 62a can be formed as screw holes (specifically, female screw holes or pilot holes for tapping screws) for threading onto the screw shank M2a of the second fastener M2 (see FIG. 10) formed by a screw, bolt, or the like.

[0074] Further, the front wall portion 62 is formed with, for example, a substantially rectangular through-hole 62b, through which the head M1b of the first fastener M1 can be rotated using a tool T. In the illustrated example, each front wall portion 62 is formed with three work holes 62b corresponding to the three board mounting holes 61a1 formed in each longitudinal portion 61a of the board portion 61, respectively.

[0075] The height of the working hole 62b is greater than the height of the head M1b (in a temporarily fixed state) of the first fastener M1. Therefore, even if the first fastener M1 is in a slightly loose state, the tool T inserted into the working hole 62b can engage with the head M1b of the first fastener M1.

[0076] Furthermore, since the positions of the front wall mounting hole 62a and the side wall mounting hole 63a are higher than the working hole 62b, even when the first fastener M1 is in a pre-tightened state where it is not fully tightened, the screw shaft M2a of the second fastener M2 does not interfere with the head M1b of the first fastener M1.

[0077] In addition, it is preferable that the width of the working hole 62b is such that, when the head M1b of the first fastener M1 is a hexagonal head (or a hexagonal hole corresponding to a hexagonal wrench), the first fastener M1 can be rotated by more than 60 degrees around its axis using a tool T.

[0078] The shape and size of the work hole 62b are not limited to this example. For example, the three work holes 62b may be formed as one continuous work hole, and as long as the head M1b of the first fastener M1 can be rotated using the tool T, the work hole 62b can be formed in any shape and size.

[0079] [Side wall] The side wall portions 63 are formed in the shape of plates extending substantially vertically upward from both end edges in the width direction of the opening / closing body of each longitudinal portion 61a of the base portion 61, and are provided with a side wall mounting hole 63a at approximately the center in the vertical and horizontal directions, for inserting the screw shank M2a of the second fastener M2 (see FIG. 10). This side wall mounting hole 63a can be formed, for example, as a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for threading onto the screw shank M2a of the second fastener M2.

[0080] <1st fastener, 2nd fastener M2, tool T> The configurations of the first fastener M1, the second fastener M2, and the tool T are similar to the configurations of the first fastener M1, the second fastener M2, and the tool T described in the guide rail installation structure above, and therefore their description will be omitted.

[0081] (Center pillar installation process) Next, we will explain the installation process for installing the center pillar 40 on the installation surface X. This installation process is similar to the installation process for the guide rail 30 described above. First, in step 1, the center pillar fixing bracket 60 is placed at the installation location of the center pillar 40 and temporarily fastened (temporarily fixed) to the installation surface X.

[0082] Next, in step 2, the lower part of the center post 40 is positioned so as to fit onto the temporarily fixed center post fixing bracket 60, and the center post fixing bracket 60 and the center post 40 are fixed together with the second fastener M2.

[0083] Next, in step 3, the installation position of the center post 40 is adjusted (fine adjustment within the adjustment margin) to a predetermined installation position, and then the first fastener M1 is fully tightened to immobilize the center post 40 on the installation surface X. In this case, a tool T is inserted into the working hole 62b formed in the front wall 62 of the center post fixing bracket 60, and the head M1b of the first fastener M1 is rotated to fully tighten.

[0084] As described above, according to the center post installation structure of the present invention, the center post 40 can be installed easily and stably on the installation surface X, thereby improving the installability of the center post 40.

[0085] (Other embodiments) Next, another example of an installation structure for a switchgear according to the present invention will be described. Fig. 11 is a schematic plan view of another guide rail to which the installation structure for a switchgear according to the present invention is applied. Fig. 12 is a schematic view showing another example of a guide rail fixing bracket for the same installation structure, and Fig. 13 is an explanatory diagram illustrating a guide rail installation structure using the same guide rail fixing bracket.

[0086] (Guide rail configuration) 11, the guide rail 70, which is a component of the opening and closing device 1, has a guide portion 70A that guides the side edge of the opening and closing body 10 in the vertical direction in the width direction of the opening and closing body, and a plurality of hollow portions 70B that form hollow spaces that are continuous in the vertical direction. Note that these plurality of hollow portions 70B are configured to communicate with each other at the bottom of the guide rail 70 to form one hollow portion (space portion), the specific configuration of which will be described later.

[0087] The guide rail 70 is formed from a metal material such as steel, stainless steel, or aluminum alloy, and is configured so that the widthwise edge of the opening / closing body 10A is surrounded by a guide portion 70A having a generally concave cross section, as shown in FIG.

[0088] This guide rail 70 has, for example, a first elongated member 71 extending in the vertical direction, a second elongated member 72 extending in the vertical direction, and a third elongated member 73 extending in the vertical direction, and these first to third members 71, 72, 73 can be joined together by a joining means such as welding to form an integrated structure.

[0089] The first member 71 has, for example, a first U-shaped portion 71a whose cross-sectional shape is formed in an approximately U-shape that opens toward the inside of the opening / closing body in the width direction, and a pair of first L-shaped portions 71b that extend toward the inside of the opening / closing body in the thickness direction and are connected approximately perpendicular to the opening edge of this first U-shaped portion 71a.

[0090] The first U-shaped portion 71a has a pair of first front wall portions 71a1 arranged opposite each other with a predetermined gap between them, and a plate-like first bottom wall portion 71a2 extending in the thickness direction of the opening / closing body and connected to each outer edge of the first front wall portion 71a1 in the width direction of the opening / closing body. The first front wall portion 71a1 of the first U-shaped portion 71a has an opening region 70C (see FIG. 13) formed therein, which exposes to the outside the working hole 82b formed in the front wall portion 82 of the guide rail fixing bracket 80 when the guide rail 70 is installed.

[0091] The first L-shaped portion 71b has a plate-shaped front wall portion 71b1 extending inward in the thickness direction of the opening / closing body, and a plate-shaped first piece portion 71b2 extending outward in the width direction of the opening / closing body and connected approximately perpendicular to the inner edge of the front wall portion 71b1 in the thickness direction of the opening / closing body.

[0092] This first member 71 is integrally formed, for example, by bending a metal plate material or by welding each portion.

[0093] The second member 72 has, for example, a second U-shaped portion 72a whose cross-sectional shape is formed in an approximately U-shape that opens in the thickness direction of the opening / closing body, and a pair of second arm portions 72b that extend outward in the thickness direction of the opening / closing body and are connected approximately perpendicular to the opening edge of this second U-shaped portion 72a.

[0094] In addition, the second U-shaped portion 72a has a second bottom wall portion 72a1 extending in the thickness direction of the opening / closing body, and a pair of second guide wall portions 72a2 extending in the width direction of the opening / closing body and connected approximately perpendicular to the thickness direction edge of this second bottom wall portion 72a1.

[0095] The second member 72 is integrally formed by, for example, bending a metal plate material or welding each portion.

[0096] The third member 73 has, for example, a generally U-shaped cross section that opens in the width direction of the opening / closing body, and includes a third bottom wall portion 73a that extends in the thickness direction of the opening / closing body, and a pair of third pieces 73b that extend in the width direction of the opening / closing body and are connected to the edge of the third bottom wall portion 73a in the thickness direction of the opening / closing body generally perpendicular to the opening / closing body. The third member 73 functions as a reinforcing portion that reinforces the guide rail 70 from its inside. This third member 73 is integrally formed by, for example, bending a metal plate material or welding each portion.

[0097] The third member 73 is provided with its lower end at a position (position H2 in FIG. 13(c)) higher than the lower ends of the first member 71 and the second member 72, and at a position higher than the height H1 of the front wall portion 82 of the guide rail fixing metal fitting 80, which will be described later. As a result, the multiple hollow portions 70B communicate with each other at the bottom of the guide rail 70 to form one hollow portion (space portion), and the guide rail fixing metal fitting 80 can be placed in this one hollow portion (space portion).

[0098] In addition, the first member 71 and the second member 72 that make up the guide rail 70 are formed with guide rail mounting holes (not shown) that can communicate with multiple mounting holes 82a, 83a1, 83b1 formed in the guide rail fixing bracket 80 (see Figure 12) described later and through which the screw shaft portion M2a of the second fastener M2 can be inserted. This guide rail attachment hole can be formed, for example, as a screw hole (specifically, a female screw hole or a pilot hole for a tapping screw) for screwing onto the screw shank M2a of the second fastener M2.

[0099] (Guide rail installation structure) Next, an example of another installation structure for a guide rail 70 according to the present invention will be described. Fig. 12 is a schematic diagram showing an example of a guide rail fixing bracket for a guide rail installation structure according to the present invention, and Fig. 13 is an explanatory diagram illustrating an installation structure for a guide rail using the same guide rail fixing bracket.

[0100] <Guide rail fixing bracket> The lower part of the guide rail 70 is fixed immovably to an installation surface X such as a floor or the ground by a guide rail fixing bracket 80 serving as an attachment member. This guide rail fixing bracket 80 has a plate-shaped base plate portion 81 placed and fixed on the installation surface X, plate-shaped front wall portions 82 extending upward substantially vertically from each end edge of the base plate portion 81 in the thickness direction of the opening / closing body, and plate-shaped side wall portions 83 extending upward substantially vertically from both end edges of the base plate portion 81 in the width direction of the opening / closing body. The guide rail fixing metal fitting 80 is formed integrally by, for example, bending a metal plate material or welding each portion together.

[0101] [Board] The base plate 81 is a portion that is fixed by contacting the installation surface X, and is formed in a generally U-shape in plan view, with a pair of long portions 81a that extend in the width direction of the opening / closing body and are arranged opposite each other, and short portions 81b that are located outside each long portion 81a in the width direction of the opening / closing body and connect the long portions 81a to each other. In other words, the base plate 81 is formed in a shape that corresponds to the cross-sectional shape of the guide rail 70 and can be placed inside the lower part of the guide rail 70.

[0102] A plurality of board mounting holes 81a1 (two in the illustrated example) are formed in each longitudinal portion 81a of the board portion 81 at predetermined intervals in the width direction of the opening / closing body. These board mounting holes 81a1 (insertion holes) are through holes for inserting the first fastener M1 (see FIG. 4), and are formed with a diameter D2 larger than the maximum diameter D1 of the screw shank M1a of the first fastener M1 (see FIG. 13(c)) (D2>D1). In other words, they are formed as through holes (so-called loose holes) with a predetermined adjustment allowance (gap = D2-D1) for inserting the screw shank M1a of the fastener M1.

[0103] [Front wall] The front wall 82 is formed in the shape of a plate extending upward substantially vertically from each edge of the base plate 81 in the thickness direction of the opening / closing body, and has a plurality of front wall mounting holes 82a (two in the illustrated example) formed at a predetermined distance apart in the width direction of the opening / closing body. These front wall mounting holes 82a can be formed as screw holes (specifically, female screw holes or pilot holes for tapping screws) for threading onto the screw shank M2a of the second fastener M2 (see FIG. 13) formed by a screw, bolt, or the like.

[0104] [Side wall] The side wall 83 has plate-like side wall portions 83a extending substantially vertically upward from one inner end edge of each long portion 81a of the base plate 81 in the width direction of the opening-closing body, and plate-like side wall portions 83b extending substantially vertically upward and continuing from the other outer end edges of each long portion 81a and each short portion 81b of the base plate 81 in the width direction of the opening-closing body. Side wall mounting holes 83a1 and 83b1 are provided in the side wall portions 83a and 83b, respectively, for inserting the screw shank M2a of the second fastener M2 (see FIG. 13). The side wall mounting holes 83a1 and 83b1 can be formed, for example, as screw holes (specifically, female screw holes or pilot holes for tapping screws) for threading onto the screw shank M2a of the second fastener M2.

[0105] Further, a work hole 82b, for example, having a substantially rectangular shape, is formed through the front wall portion 82, and the head M1b of the first fastener M1 can be rotated through this work hole 82b using a tool T. In the illustrated example, two work holes 82b are formed in each front wall portion 82, corresponding respectively to the two board mounting holes 81a1 formed in each longitudinal portion 81a of the board portion 81.

[0106] The height of the working hole 82b is greater than the height of the head M1b (in a temporarily fixed state) of the first fastener M1. Therefore, even if the first fastener M1 is in a slightly loose state, the tool T inserted into the working hole 82b can engage with the head M1b of the first fastener M1.

[0107] Furthermore, since the positions of the front wall mounting hole 82a and the side wall mounting hole 83a are higher than the working hole 82b, even when the first fastener M1 is in a pre-tightened state where it is not fully tightened, the screw shaft M2a of the second fastener M2 does not interfere with the head M1b of the first fastener M1.

[0108] In addition, it is preferable that the width of the working hole 82b is such that, when the head M1b of the first fastener M1 is a hexagonal head (or a hexagonal hole corresponding to a hexagonal wrench), the first fastener M1 can be rotated by more than 60 degrees around its axis using a tool T.

[0109] The shape and size of the working hole 82b are not limited to this example. For example, the two working holes 82b may be formed as a single continuous working hole, and as long as the head M1b of the first fastener M1 can be rotated using the tool T, the working hole 82b can be formed in any shape and size.

[0110] <1st fastener, 2nd fastener M2, tool T> The configurations of the first fastener M1, the second fastener M2, and the tool T are similar to the configurations of the first fastener M1, the second fastener M2, and the tool T described in the guide rail installation structure above, and therefore their description will be omitted.

[0111] (Guide rail installation process) Next, we will explain the installation process for installing the guide rail 70 on the installation surface X. This installation process is similar to the installation process for the guide rail 30 described above, and first, in step 1, the guide rail fixing metal fitting 80 is placed at the installation location of the guide rail 70 and temporarily fastened (temporarily fixed) onto the installation surface X.

[0112] When installing the above-mentioned guide rail 30, as shown in FIG. 4(a), two guide rail fixing brackets 50 were placed on the installation surface X to correspond to each hollow portion 30B (see FIG. 2) of the guide rail 30. However, when installing the guide rail 70, a single hollow portion (space portion) is formed in communication at the bottom of the guide rail 70, so it is sufficient to place one guide rail fixing bracket 80 on the installation surface X, which further improves workability.

[0113] Next, in step 2, the lower part of the guide rail 70 is positioned so as to fit onto the temporarily fixed guide rail fixing metal fitting 80, and the guide rail fixing metal fitting 80 and the guide rail 70 are fixed together with the second fastener M2.

[0114] Next, in step 3, the installation position of the guide rail 70 is adjusted (finely adjusted within the adjustment margin) to a predetermined installation position, and then the first fastener M1 is fully tightened to immobilize the guide rail 70 relative to the installation surface X. In this case, a tool T is inserted into an operation hole 82b formed in the front wall portion 82 of the guide rail fixing metal fitting 80, and the head M1b of the first fastener M1 is rotated to fully tighten.

[0115] As described above, according to the center pillar installation structure of the present invention, the guide rail 70 can be easily and stably installed on the installation surface X, thereby improving the installability of the guide rail 70.

[0116] The present invention is not limited to the specific configuration described above, and can be modified as appropriate within the scope of the present invention. For example, a fire-resistant or heat-resistant fireproof member (not shown) may be arranged between the base plate portion 51, 61, 81 of the guide rail fixing bracket 50, 80 or the center pillar fixing bracket 60 and the installation surface X. In this case, the fireproof member may be, for example, a fireproof sheet made of fire-resistant or heat-resistant silica cloth or glass cloth. By arranging such a fireproof member, in the event of a fire, thermal deterioration (damage) around the threaded shank M1a of the first fastener M1 that screws into the installation surface X can be prevented, and the guide rail 30, 70 and the center pillar 40 can be maintained in a stable installation state.
