大型な電気設備において、設置スペースを小さくしてスペースを有効に活用することが望まれているので、このような電気設備は薄型化される傾向にある。しかしながら、薄型化によって、電気設備は外的荷重に対して転倒するおそれが高くなる。そのため、電気設備を屋外の地上に設置する場合、強固な基礎打ちが必要になる。このような基礎打ちの工期は一般的に長い。また、既設などの基礎打ち不可能な設置場所もある。 In large-scale electrical equipment, it is desired to reduce the installation space and effectively utilize the space, so such electrical equipment tends to be thinned. However, due to the thinning, the electrical equipment is more likely to tip over due to an external load. Therefore, when installing electrical equipment on the ground outdoors, a solid foundation is required. The construction period for such foundations is generally long. In addition, there are some installation locations such as existing ones where it is not possible to strike a foundation.

本発明はこうした状況に鑑みなされたものであり、その目的は、筐体を容易に固定する技術を提供することにある。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique for easily fixing a housing.

上記課題を解決するために、本発明のある態様の固定方法は、筐体の底面に着脱可能な底面カバーを筐体から取り外した状態において、底面カバーの固定部に合わせた位置に、筐体を下方から支持する複数の支持部材を配置するステップと、支持部材に設けられた溝に、複数の固定部品を溝に沿って移動させながら取りつけるステップと、複数の支持部材のそれぞれに底面カバーの固定部を取り付けるステップと、複数の支持部材に取り付けた底面カバーに、筐体の底面を取り付けるステップと、筐体のうち壁に対向する側面に第１固定部を取り付けるステップと、第１固定部に第２固定部を取り付けるステップと、第２固定部を壁に取り付けるステップとを備える。第１固定部は、筐体のうち壁に対向する側面に取り付けられる第１固定面と、第１固定面から壁の方向に延びる第１分割片とを含み、第２固定部は、壁に取り付け可能な第２固定面と、第２固定面から筐体に向かって伸びる第２分割片とを含み、第１分割片と第２分割片との一部は互いに重なり合って連結される。 In order to solve the above problems, the fixing method of an aspect of the present invention is to remove the bottom cover that can be attached to and detached from the bottom surface of the housing from the housing, and to position the housing at a position that matches the fixing portion of the bottom cover. A step of arranging a plurality of support members for supporting the support member from below, a step of attaching a plurality of fixing parts to a groove provided in the support member while moving along the groove, and a step of attaching a bottom cover to each of the plurality of support members. A step of attaching the fixing part, a step of attaching the bottom surface of the housing to the bottom covers attached to a plurality of support members, a step of attaching the first fixing part to the side surface of the housing facing the wall, and a first fixing part. A step of attaching the second fixing portion to the wall and a step of attaching the second fixing portion to the wall are provided. The first fixing portion includes a first fixing surface attached to a side surface of the housing facing the wall and a first divided piece extending from the first fixing surface in the direction of the wall, and the second fixing portion is attached to the wall. A second fixed surface to be attached and a second divided piece extending from the second fixed surface toward the housing are included, and a part of the first divided piece and the second divided piece are connected so as to overlap each other .

本発明の別の態様は、電気設備である。この電気設備は、筐体と、筐体の底面に着脱可能な底面カバーと、底面カバーに固定されることによって、筐体を下方から支持する複数の支持部材と、複数の支持部材から上方に突出する固定部品と、筐体の高さの下から２分の１の範囲である下半分に取り付けられる固定部材と、を備える。底面カバーは、複数の支持部材から延びる固定部品それぞれを取り付ける固定部を含み、底面カバーは、固定部と固定部品とによって筐体の底面に接するように位置決めされて取り付けられる。固定部材は、筐体のうち壁に対向する側面に取り付けられる第１固定面と、第１固定面から壁の方向に延びる第１分割片と、壁に取り付け可能な第２固定面と、第２固定面から筐体に向かって伸びる第２分割片と、を含み、第１分割片と第２分割片との一部は互いに重なり合って連結される。 Another aspect of the present invention is electrical equipment. This electrical equipment includes a housing, a bottom cover that can be attached to and detached from the bottom of the housing, a plurality of support members that support the housing from below by being fixed to the bottom cover, and a plurality of support members that support the housing from below. It includes a protruding fixing component and a fixing member attached to the lower half, which is a half of the height of the housing. The bottom cover includes a fixing portion for attaching each of the fixing parts extending from the plurality of support members, and the bottom cover is positioned and attached so as to be in contact with the bottom surface of the housing by the fixing portion and the fixing component. The fixing member includes a first fixing surface attached to the side surface of the housing facing the wall, a first dividing piece extending from the first fixing surface in the direction of the wall, a second fixing surface that can be attached to the wall, and a first portion. 2. A second divided piece extending from the fixed surface toward the housing is included, and a part of the first divided piece and the second divided piece are connected to each other so as to overlap each other .

本発明の実施例を具体的に説明する前に、実施例の概要を説明する。実施例は、屋外に設置される電気設備に関する。電気設備の一例は電力変換装置である。設置スペースを縮小するために、前述のごとく、電気設備の筐体は薄型化される。薄型化されると、筐体は、地震、台風等によって加えられる外的荷重に対して転倒しやすくなる。しかしながら、このような転倒を防止するために基礎打ちを実行する場合、工期が長くなる。筐体を固定するための工期を短縮するために、筐体を容易にかつ強固に固定することが求められる。これに対応するために本実施例に係る電気設備は次のように構成される。 An outline of the examples will be described before the examples of the present invention are specifically described. Examples relate to electrical equipment installed outdoors. An example of electrical equipment is a power converter. As described above, the housing of the electrical equipment is made thinner in order to reduce the installation space. When the thickness is reduced, the housing is likely to tip over due to an external load applied by an earthquake, a typhoon, or the like. However, when the foundation is struck to prevent such a fall, the construction period becomes long. In order to shorten the construction period for fixing the housing, it is required to fix the housing easily and firmly. In order to deal with this, the electrical equipment according to this embodiment is configured as follows.

建物の側の地面上に、筐体を下方から支持するための複数の支持部材が配置される。複数の支持部材を配置する位置は、筐体の底面に取付可能な底面カバーの固定部の位置に合わせるようにが決められる。また、配置された複数の支持部材に取り付けられた底面カバーに対して、筐体が底面から取り付けられる。一方、筐体が設置される側の建物では、下部に基礎部分が配置され、基礎部分の上に建物壁が配置される。基礎部分と筐体は固定部材によって接続されるとともに、建物壁と筐体は転倒防止部材によって接続される。なお、以下の説明において、「平行」、「垂直」は、完全な平行、垂直だけではなく、誤差の範囲で平行、垂直からずれている場合も含むものとする。また、「略」は、おおよその範囲で同一であるという意味である。 A plurality of support members for supporting the housing from below are arranged on the ground on the side of the building. The position where the plurality of support members are arranged is determined so as to match the position of the fixed portion of the bottom cover that can be attached to the bottom surface of the housing. Further, the housing is attached from the bottom surface to the bottom surface covers attached to the plurality of arranged support members. On the other hand, in the building on the side where the housing is installed, the foundation portion is arranged at the lower part, and the building wall is arranged above the foundation portion. The foundation portion and the housing are connected by a fixing member, and the building wall and the housing are connected by a fall prevention member. In the following description, "parallel" and "vertical" include not only perfectly parallel and vertical, but also cases where they are deviated from parallel and vertical within the margin of error. In addition, "abbreviation" means that they are the same in an approximate range.

図１（ａ）−（ｂ）は、本発明の実施例に係る電気設備１００の外観を示す。図１（ａ）に示すように、ｘ軸、ｙ軸、ｚ軸からなる直交座標系が規定される。ｘ軸、ｙ軸は、地面８内あるいは筐体１０の底面内において互いに直交する。ｚ軸は、ｘ軸およびｙ軸に垂直であり、筐体１０の高さ（垂直）方向に延びる。また、ｘ軸、ｙ軸、ｚ軸のそれぞれの正の方向は、図１（ａ）における矢印の方向に規定され、負の方向は、矢印と逆向きの方向に規定される。そのため、図１（ａ）は、電気設備１００をｘ軸の正方向側から見た構成であり、図１（ｂ）は、電気設備１００をｙ軸の正方向側から見た構成である。図１（ａ）−（ｂ）に示すように、ここでは、電気設備１００を屋外に設置する場合を例示する。 1 (a)-(b) show the appearance of the electric equipment 100 according to the embodiment of the present invention. As shown in FIG. 1A, a Cartesian coordinate system including an x-axis, a y-axis, and a z-axis is defined. The x-axis and y-axis are orthogonal to each other in the ground 8 or the bottom surface of the housing 10. The z-axis is perpendicular to the x-axis and the y-axis and extends in the height (vertical) direction of the housing 10. Further, the positive directions of the x-axis, the y-axis, and the z-axis are defined in the direction of the arrow in FIG. 1A, and the negative direction is defined in the direction opposite to the arrow. Therefore, FIG. 1A is a configuration in which the electrical equipment 100 is viewed from the positive direction side of the x-axis, and FIG. 1B is a configuration in which the electrical equipment 100 is viewed from the positive direction side of the y-axis. As shown in FIGS. 1 (a)-(b), here, a case where the electric equipment 100 is installed outdoors will be illustrated.

立壁２は、建物の基礎部分４と、建物壁６を含む。基礎部分４は、建物からの力を地面８に伝えて、建物を安全に支える機能をもつ構造であり、例えばコンクリートにより構成される。基礎部分４は、ｘ−ｙ平面上に広がるとともに、端部、例えば、図１（ｂ）のｘ軸の正方向側の端部においてｚ軸方向にも延びる。建物壁６は、基礎部分４のｚ軸の正方向側端からｚ軸方向に延びる。建物壁６は建物の壁であり、特に、電気設備１００を建物の１階に設置する場合、建物壁６は１階部分の壁に相当する。また、建物が木造住宅である場合、例えば、建物壁６はモルタル、タイル等の壁材により構成される。建物壁６には、２２ｋＮ程度の壁強度が要求される。地面８は、基礎打ちがなされていない土壌である。特に地面８は、強固で自重、凍結氷解などにより陥没しない場所とされるとともに、電気設備１００の設置面が水平な場所とされる。 The standing wall 2 includes the foundation portion 4 of the building and the building wall 6. The foundation portion 4 is a structure having a function of transmitting the force from the building to the ground 8 to safely support the building, and is composed of, for example, concrete. The foundation portion 4 extends on the xy plane and also extends in the z-axis direction at an end portion, for example, an end portion on the positive direction side of the x-axis in FIG. 1 (b). The building wall 6 extends in the z-axis direction from the positive end of the foundation portion 4 on the z-axis. The building wall 6 is a wall of the building, and in particular, when the electrical equipment 100 is installed on the first floor of the building, the building wall 6 corresponds to the wall of the first floor portion. When the building is a wooden house, for example, the building wall 6 is made of a wall material such as mortar or tile. The building wall 6 is required to have a wall strength of about 22 kN. Ground 8 is soil that has not been grounded. In particular, the ground 8 is a place that is strong and does not sink due to its own weight, freezing and icing, and the installation surface of the electrical equipment 100 is horizontal.

筐体１０は、本体２０とベース３０とがｚ軸方向に接続されて構成される。本体２０は、ベース３０のｚ軸の正方向側において、建物壁６に対応した高さに配置される。本体２０は、ｘ−ｙ平面およびｚ−ｘ平面よりもｙ−ｚ平面が広い矩形箱形の形状を有し、金属製の板材が曲げ加工されることで形成される。本体２０は、ｘ軸の正方向側の面が開口した矩形箱形の形状の本体ボディ２２と、本体ボディ２２の開口を覆う本体カバー２４とで構成される。電気設備１００が電力変換装置である場合、本体ボディ２２の内部には電力変換ユニットが収納される。ここで、本体ボディ２２を構成する複数の側面、つまりｚ軸が含まれた側面のうち、建物壁６に対向した側面には本体背面板２８が配置される。本体カバー２４は本体ボディ２２にネジ止めされる。また、本体カバー２４と本体ボディ２２との間から水が進入することを防止するために、本体カバー２４と本体ボディ２２との間に防水パッキンが設けられてもよい。 The housing 10 is configured by connecting the main body 20 and the base 30 in the z-axis direction. The main body 20 is arranged at a height corresponding to the building wall 6 on the positive direction side of the z-axis of the base 30. The main body 20 has a rectangular box-shaped shape in which the yz plane is wider than the xy plane and the zxx plane, and is formed by bending a metal plate material. The main body 20 is composed of a rectangular box-shaped main body 22 having an opening on the positive direction side of the x-axis, and a main body cover 24 covering the opening of the main body 22. When the electric equipment 100 is a power conversion device, the power conversion unit is housed inside the main body 22. Here, among the plurality of side surfaces constituting the main body 22, that is, the side surfaces including the z-axis, the main body back plate 28 is arranged on the side surface facing the building wall 6. The main body cover 24 is screwed to the main body 22. Further, in order to prevent water from entering between the main body cover 24 and the main body 22, a waterproof packing may be provided between the main body cover 24 and the main body 22.

ベース３０は、基礎部分４に対応した高さに配置される。ベース３０は、ｘ−ｙ平面およびｚ−ｘ平面よりもｙ−ｚ平面が広い矩形箱形の形状を有し、金属製の板材が曲げ加工されることで形成される。ベース３０は、ｘ軸の正方向側の面が開口した矩形箱形の形状のベースボディ３２と、ベースボディ３２の開口を覆うベースカバー３４とで構成される。ベースボディ３２、ベースカバー３４は、本体ボディ２２、本体カバー２４と同様に構成されるので、ここでは説明を省略する。なお、ベースボディ３２を構成する複数の側面のうち、基礎部分４に対向した側面にはベース背面板３８が配置される。 The base 30 is arranged at a height corresponding to the foundation portion 4. The base 30 has a rectangular box-shaped shape in which the yz plane is wider than the xy plane and the zxx plane, and is formed by bending a metal plate material. The base 30 is composed of a rectangular box-shaped base body 32 having an opening on the positive direction side of the x-axis, and a base cover 34 covering the opening of the base body 32. Since the base body 32 and the base cover 34 are configured in the same manner as the main body 22 and the main body cover 24, description thereof will be omitted here. Of the plurality of side surfaces constituting the base body 32, the base back plate 38 is arranged on the side surface facing the base portion 4.

固定部材１２は、ベース３０を基礎部分４に固定するための部材であり、例えば、金属により形成される。ここで、固定部材１２は、ベース背面板３８に取り付けられるとともに、基礎部分４にも取り付けられる。このように固定部材１２は、立壁２に対向した筐体１０の側面のうち、筐体１０のｚ軸方向の高さの下から１／２の範囲である下半分の部分に取り付けられる。また、詳細は後述するが、固定部材１２によって、ベース背面板３８と基礎部分４とのｘ軸方向の距離「Ａ」が、例えば、７５ｍｍあるいは１００ｍｍに設定される。 The fixing member 12 is a member for fixing the base 30 to the foundation portion 4, and is formed of, for example, metal. Here, the fixing member 12 is attached to the base back plate 38 and also to the base portion 4. In this way, the fixing member 12 is attached to the lower half of the side surface of the housing 10 facing the vertical wall 2 which is a range of 1/2 from the bottom of the height of the housing 10 in the z-axis direction. Further, as will be described in detail later, the fixing member 12 sets the distance “A” between the base back plate 38 and the base portion 4 in the x-axis direction to, for example, 75 mm or 100 mm.

第１支持部材１４ａ、第２支持部材１４ｂは、支持部材１４と総称される。支持部材１４は、地面８上に直置きされ、ベースボディ３２に固定されることによって、筐体１０をｚ軸の負方向側から支持する。なお、ベースボディ３２への固定については後述する。支持部材１４は、矩形箱形の形状を有し、例えば、コンクリートにより形成される。転倒防止部材１６は、本体２０を建物壁６に固定するための部材であり、例えば、金属により形成される。ここで、転倒防止部材１６は、本体２０の上に取り付けられるとともに、建物壁６にも取り付けられる。このように転倒防止部材１６は、筐体１０のｚ軸方向の高さの上から１／２の範囲である上半分の部分に取り付けられる。転倒防止部材１６は、金属製の板材で形成される。また、詳細は後述するが、転倒防止部材１６によって、本体背面板２８と建物壁６とのｘ軸方向の距離が、例えば、５０ｍｍ〜１２０ｍｍに設定される。 The first support member 14a and the second support member 14b are collectively referred to as the support member 14. The support member 14 is placed directly on the ground 8 and fixed to the base body 32 to support the housing 10 from the negative direction side of the z-axis. The fixing to the base body 32 will be described later. The support member 14 has a rectangular box shape and is formed of, for example, concrete. The fall prevention member 16 is a member for fixing the main body 20 to the building wall 6, and is formed of, for example, metal. Here, the fall prevention member 16 is mounted on the main body 20 as well as on the building wall 6. In this way, the fall prevention member 16 is attached to the upper half portion of the housing 10 which is in the range of 1/2 from the height in the z-axis direction. The fall prevention member 16 is made of a metal plate material. Further, as will be described in detail later, the fall prevention member 16 sets the distance between the main body back plate 28 and the building wall 6 in the x-axis direction to, for example, 50 mm to 120 mm.

従来のように、筐体１０を設置するために基礎打ちがなされる場合、コンクリートの現場打ちによって工期が長くなる。また、根入れ、つまり杭、基礎、擁壁などを地中に埋設するために、根入れ部の地中配管経路の確認が必要になり、配管が存在すれば設置場所が制約される。一方、本実施例のように、固定部材１２、支持部材１４、転倒防止部材１６によって筐体１０を固定すれば、基礎打ち等が不要になる。 When the foundation is cast to install the housing 10 as in the conventional case, the construction period is lengthened by the on-site casting of concrete. In addition, in order to embed, that is, to bury piles, foundations, retaining walls, etc. in the ground, it is necessary to confirm the underground piping route of the embedding part, and if piping exists, the installation location is restricted. On the other hand, if the housing 10 is fixed by the fixing member 12, the support member 14, and the fall prevention member 16 as in the present embodiment, foundation striking or the like becomes unnecessary.

図２は、電気設備１００の内部構成を示す正面図である。前述のごとく、電気設備１００の一例は電力変換装置であり、電力変換装置は、太陽電池、蓄電池などの外部電源が出力する直流電力を交流電力に変換して、商用電源系統と連系させる系統出力または負荷を自立運転させる自立出力に出力する。なお、電気設備１００は、電力変換装置以外であってもよい。図２において、本体２０から本体カバー２４が取り外されるとともに、ベース３０からベースカバー３４が取り外されている。そのため、本体ボディ２２では、ｘ軸の正方向側において本体開口部２６が開口し、ベースボディ３２では、ｘ軸の正方向側においてベース開口部３６が開口する。 FIG. 2 is a front view showing the internal configuration of the electrical equipment 100. As described above, an example of the electric equipment 100 is a power conversion device, and the power conversion device is a system that converts DC power output from an external power source such as a solar cell or a storage battery into AC power and connects it to a commercial power supply system. Output the output or load to the self-sustaining output that makes the load operate independently. The electric equipment 100 may be other than the power conversion device. In FIG. 2, the main body cover 24 is removed from the main body 20, and the base cover 34 is removed from the base 30. Therefore, in the main body 22, the main body opening 26 opens on the positive direction side of the x-axis, and in the base body 32, the base opening 36 opens on the positive direction side of the x-axis.

本体ボディ２２内には電力変換ユニット４０が収納される。電力変換ユニット４０は、外部電源（図示なし）に接続され、外部電源からの直流電力を交流電力に変換する。また、電力変換ユニット４０は、屋内に設置された分電盤のブレーカ（図示なし）、あるいはベースボディ３２に収納された切換ユニット４２を介して、変換した交流電力を負荷に供給する。さらに、電力変換ユニット４０は、太陽電池の発電電力および系統電源からの供給電力を用いて蓄電池を充電したり、太陽電池の発電電力を系統電源に逆潮流させて売電したりする。ベースボディ３２内には切換ユニット４２と、トランス４４が収納される。切換ユニット４２は、接続された負荷に対して、太陽電池、蓄電池からの電力を停電時に供給するために、自立運転モードへの切換を実行する。トランス４４は、電力変換ユニット４０から供給される交流電圧を２線式から３線式に変換する。 The power conversion unit 40 is housed in the main body 22. The power conversion unit 40 is connected to an external power source (not shown) and converts DC power from the external power source into AC power. Further, the power conversion unit 40 supplies the converted AC power to the load via a breaker (not shown) of a distribution board installed indoors or a switching unit 42 housed in the base body 32. Further, the power conversion unit 40 charges the storage battery by using the power generated by the solar cell and the power supplied from the grid power source, or reverse-feeds the generated power of the solar cell to the grid power source to sell the power. The switching unit 42 and the transformer 44 are housed in the base body 32. The switching unit 42 executes switching to the self-sustaining operation mode in order to supply electric power from the solar cell and the storage battery to the connected load in the event of a power failure. The transformer 44 converts the AC voltage supplied from the power conversion unit 40 from the 2-wire system to the 3-wire system.

このような構成のもと、以下では、（１）固定部材１２、支持部材１４、ベース３０の構成を説明した後、（２）転倒防止部材１６、本体２０の構成を説明する。さらに、これらに続いて、（３）電気設備１００の固定方法を説明する。 Based on such a configuration, the configurations of (1) the fixing member 12, the support member 14, and the base 30 will be described below, and then (2) the configurations of the fall prevention member 16 and the main body 20 will be described. Further, following these, (3) a method of fixing the electrical equipment 100 will be described.

（１）固定部材１２、支持部材１４、ベース３０の構成
図３（ａ）−（ｂ）は、固定部材１２、支持部材１４、ベース３０の構成を示す斜視図である。図４は、固定部材１２、支持部材１４、ベース３０の構成を示す分解斜視図である。図５（ａ）−（ｃ）は、固定部材１２の構成を示す。前述のごとく、ベースボディ３２のｘ軸の正方向側にはベース開口部３６が配置され、ｘ軸の負方向側にはベース背面板３８が配置される。ベース背面板３８には、固定部材１２が取り付けられる。固定部材１２は、第１固定部５０、第２固定部５２を含む。 (1) Configuration of Fixing Member 12, Supporting Member 14, and Base 30 FIGS. 3 (a)-(b) are perspective views showing the configuration of the fixing member 12, the supporting member 14, and the base 30. FIG. 4 is an exploded perspective view showing the configurations of the fixing member 12, the supporting member 14, and the base 30. 5 (a)-(c) show the structure of the fixing member 12. As described above, the base opening 36 is arranged on the positive side of the x-axis of the base body 32, and the base back plate 38 is arranged on the negative side of the x-axis. A fixing member 12 is attached to the base back plate 38. The fixing member 12 includes a first fixing portion 50 and a second fixing portion 52.

第１固定部５０は、第１固定面５４、第１分割片５６を含んでおり、これらは一体的に形成される。第１固定面５４は、ｚ軸方向よりもｙ軸方向に長い矩形状を有し、ベース背面板３８に取付可能である。また、第１固定面５４のｙ軸方向の両端のそれぞれからｘ軸の負方向側に延びるように第１分割片５６が設けられる。このように、第１固定部５０は、ｚ軸方向から見た場合、第１固定面５４とこれを挟む２つの第１分割片５６によってＵ字形をなす。 The first fixing portion 50 includes a first fixing surface 54 and a first dividing piece 56, which are integrally formed. The first fixed surface 54 has a rectangular shape that is longer in the y-axis direction than in the z-axis direction, and can be attached to the base back plate 38. Further, the first divided piece 56 is provided so as to extend from both ends of the first fixed surface 54 in the y-axis direction to the negative direction side of the x-axis. As described above, the first fixed portion 50 is U-shaped when viewed from the z-axis direction by the first fixed surface 54 and the two first divided pieces 56 sandwiching the first fixed surface 54.

第２固定部５２は、第２固定面５８、第２分割片６０を含んでおり、これらは一体的に形成される。第２固定面５８は、ｙ−ｚ平面において矩形状を有し、基礎部分４（図示せず）に取付可能である。また、第２固定面５８のｙ軸方向の一端からｘ軸の正方向に延びるように第２分割片６０が設けられる。なお、２つの第２固定部５２は、ｘ軸を回転軸として１８０度回転させた形状を有する。このように、第２固定部５２は、ｚ軸方向から見た場合、第２固定面５８と第２分割片６０によってＬ字形をなす。 The second fixing portion 52 includes a second fixing surface 58 and a second dividing piece 60, which are integrally formed. The second fixed surface 58 has a rectangular shape in the yz plane and can be attached to the foundation portion 4 (not shown). Further, the second divided piece 60 is provided so as to extend from one end of the second fixed surface 58 in the y-axis direction in the positive direction of the x-axis. The two second fixing portions 52 have a shape rotated by 180 degrees with the x-axis as a rotation axis. As described above, the second fixed portion 52 is L-shaped by the second fixed surface 58 and the second divided piece 60 when viewed from the z-axis direction.

第１固定部５０の第１分割片５６と、第２固定部５２の第２分割片６０は、少なくとも一部が重なり合うように平行に並べられて連結される。その際、ｙ−ｚ平面において、２つの第２固定面５８が第１固定面５４を挟むように、第２固定部５２が配置される。ここで、ベース背面板３８のｙ軸方向の幅は、第１固定部５０に２つの第２固定部５２が連結された固定部材１２のｙ軸方向の幅よりも広くされる。 The first divided piece 56 of the first fixed portion 50 and the second divided piece 60 of the second fixed portion 52 are arranged and connected in parallel so that at least a part of them overlap each other. At that time, the second fixing portion 52 is arranged so that the two second fixing surfaces 58 sandwich the first fixing surface 54 in the yz plane. Here, the width of the base back plate 38 in the y-axis direction is wider than the width of the fixing member 12 in which the two second fixing portions 52 are connected to the first fixing portion 50 in the y-axis direction.

ここでは、第１分割片５６と第２分割片６０との連結をさらに詳細に説明する。第１分割片５６には、２つの連結孔６２がｚ軸方向に並んで配置される。ここで、連結孔６２は、ｘ軸方向よりもｚ軸方向に長いスリット形状に開口された貫通孔である。また、第２分割片６０には、２つの連結孔６４がｚ軸方向に並んで配置されるとともに、２つの連結孔６４の組合せ（以下、「組合せ」ということもある）がさらにｘ軸方向に並べられる。そのため、第２分割片６０には４つの連結孔６４が配置される。連結孔６４は、円形状に開口された貫通孔である。なお、連結孔６２の数、連結孔６４の数は、これらに限定されない。 Here, the connection between the first divided piece 56 and the second divided piece 60 will be described in more detail. Two connecting holes 62 are arranged side by side in the z-axis direction in the first divided piece 56. Here, the connecting hole 62 is a through hole opened in a slit shape longer in the z-axis direction than in the x-axis direction. Further, in the second dividing piece 60, two connecting holes 64 are arranged side by side in the z-axis direction, and a combination of the two connecting holes 64 (hereinafter, also referred to as “combination”) is further arranged in the x-axis direction. Lined up in. Therefore, four connecting holes 64 are arranged in the second divided piece 60. The connecting hole 64 is a through hole opened in a circular shape. The number of connecting holes 62 and the number of connecting holes 64 are not limited to these.

図１（ｂ）に示した距離「Ａ」に応じて、第２分割片６０においてｘ軸方向に並んだ２つの組合せの一方が選択され、選択された組合せに含まれた２つの連結孔６４と、連結孔６２を合わせるようにして、第１分割片５６と第２分割片６０が重ねられる。この状態において、連結孔６２と連結孔６４とを貫通するように連結ネジ６６が挿入される。この部分の断面が図５（ｂ）−（ｃ）に示される。図５（ｂ）−（ｃ）では、連結ネジ６６、連結孔６２の形状が異なっているだけであり、どちらで構成されてもよい。 One of the two combinations arranged in the x-axis direction is selected in the second dividing piece 60 according to the distance "A" shown in FIG. 1 (b), and the two connecting holes 64 included in the selected combination. The first division piece 56 and the second division piece 60 are overlapped with each other so that the connecting holes 62 are aligned with each other. In this state, the connecting screw 66 is inserted so as to penetrate the connecting hole 62 and the connecting hole 64. A cross section of this portion is shown in FIGS. 5 (b)-(c). In FIGS. 5 (b)-(c), only the shapes of the connecting screw 66 and the connecting hole 62 are different, and either of them may be used.

図５（ｂ）において、連結孔６２の縁部には、連結ネジ６６が進入する方向に延びるスペーサ８２が設けられる。連結ネジ６６が進入する方向におけるスペーサ８２の長さは、当該方向における第１分割片５６および第２分割片６０の厚さよりも長くされる。また、連結孔６４の開口面積は、スペーサ８２を貫通可能な広さにされる。このような構成において、連結孔６４にスペーサ８２を貫通させながら、第１分割片５６と第２分割片６０が重ねられる。これに続いて、それらの第１分割片５６側から連結ネジ６６が挿入され、第２分割片６０側において連結ネジ６６が連結ナット６８によって締められる。このような構成によって、第１分割片５６と第２分割片６０との連結された場合であっても、第１分割片５６と第２分割片６０との密着が防止される。 In FIG. 5B, a spacer 82 extending in the direction in which the connecting screw 66 enters is provided at the edge of the connecting hole 62. The length of the spacer 82 in the direction in which the connecting screw 66 enters is made longer than the thickness of the first dividing piece 56 and the second dividing piece 60 in that direction. Further, the opening area of the connecting hole 64 is set to a size that allows the spacer 82 to penetrate. In such a configuration, the first division piece 56 and the second division piece 60 are overlapped while the spacer 82 is passed through the connecting hole 64. Following this, the connecting screw 66 is inserted from the first split piece 56 side, and the connecting screw 66 is tightened by the connecting nut 68 on the second split piece 60 side. With such a configuration, even when the first divided piece 56 and the second divided piece 60 are connected, the contact between the first divided piece 56 and the second divided piece 60 is prevented.

図５（ｃ）において、連結ネジ６６の胴部には段部８４が設けられる。連結ネジ６６が進入する方向における段部８４の長さは、当該方向における第１分割片５６および第２分割片６０の厚さよりも長くされる。また、連結孔６２および連結孔６４の開口面積は、段部８４を貫通可能な広さにされる。このような構成において、連結孔６２と連結孔６４とが合わされるように、第１分割片５６と第２分割片６０が重ねられる。それらの第１分割片５６側から連結ネジ６６が挿入され、第２分割片６０側において連結ネジ６６が連結ナット６８によって締められる。その際、連結孔６２と連結孔６４には段部８４が配置される。このような構成によって、第１分割片５６と第２分割片６０との連結された場合であっても、第１分割片５６と第２分割片６０との密着が防止される。 In FIG. 5C, a step portion 84 is provided on the body portion of the connecting screw 66. The length of the step portion 84 in the direction in which the connecting screw 66 enters is made longer than the thickness of the first division piece 56 and the second division piece 60 in that direction. Further, the opening areas of the connecting holes 62 and the connecting holes 64 are made wide enough to penetrate the stepped portion 84. In such a configuration, the first divided piece 56 and the second divided piece 60 are overlapped so that the connecting hole 62 and the connecting hole 64 are aligned. The connecting screw 66 is inserted from the first split piece 56 side, and the connecting screw 66 is tightened by the connecting nut 68 on the second split piece 60 side. At that time, a step portion 84 is arranged in the connecting hole 62 and the connecting hole 64. With such a configuration, even when the first divided piece 56 and the second divided piece 60 are connected, the contact between the first divided piece 56 and the second divided piece 60 is prevented.

このような第１固定部５０における第１固定面５４は、図３（ａ）−（ｂ）、図４のごとく、ベース背面板３８に重ねられる。また、第１固定面５４に設けられた固定孔７６と、ベース背面板３８に設けられた固定孔７４とを介して、固定ネジ７０と固定ナット７８とが結合されることによって、ベース背面板３８に第１固定部５０が固定される。その際、固定座金７２が間に挿入されてもよい。また、第２固定部５２における第２固定面５８には固定孔８０が設けられており、固定孔８０を介してアンカーボルト（図示せず）が基礎部分４に結合されることによって、基礎部分４に第２固定部５２が固定される。このように、固定部材１２によってベース３０は基礎部分４に固定される。 The first fixing surface 54 of the first fixing portion 50 is overlapped with the base back plate 38 as shown in FIGS. 3 (a)-(b) and 4. Further, the fixing screw 70 and the fixing nut 78 are connected to each other via the fixing hole 76 provided in the first fixing surface 54 and the fixing hole 74 provided in the base back plate 38, whereby the base back plate is formed. The first fixing portion 50 is fixed to 38. At that time, the fixed washer 72 may be inserted in between. Further, a fixing hole 80 is provided in the second fixing surface 58 of the second fixing portion 52, and an anchor bolt (not shown) is connected to the foundation portion 4 via the fixing hole 80, whereby the foundation portion The second fixing portion 52 is fixed to 4. In this way, the base 30 is fixed to the foundation portion 4 by the fixing member 12.

連結孔６２がｚ軸方向の長孔形状であり、かつ第１分割片５６と第２分割片６０とが密着しないので、第１固定部５０は、第２固定部５２に対して、筐体１０の側面に沿った方向、具体的にはｚ方向に移動可能である。これにより、固定部材１２によってベース３０が基礎部分４に固定された状態において、土壌の陥没等により、筐体１０がｚ軸の負方向に沈んだ場合であっても、第１固定部５０はｚ軸の負方向にスライドする。これにより、第２固定部５２に加わる荷重が低減されるので、基礎部分４に加わる荷重も低減される。 Since the connecting hole 62 has an elongated hole shape in the z-axis direction and the first dividing piece 56 and the second dividing piece 60 do not come into close contact with each other, the first fixing portion 50 has a housing with respect to the second fixing portion 52. It can move in the direction along the side surface of 10, specifically in the z direction. As a result, in a state where the base 30 is fixed to the foundation portion 4 by the fixing member 12, even if the housing 10 sinks in the negative direction of the z-axis due to the depression of soil or the like, the first fixing portion 50 can be used. Slide in the negative direction of the z-axis. As a result, the load applied to the second fixing portion 52 is reduced, so that the load applied to the foundation portion 4 is also reduced.

次に、支持部材１４の構成を説明するが、説明を明瞭にするために、これまでの図面に加えて図６も使用する。図６は、ベース３０の構成を示す斜視図である。ベース３０のｚ軸の負方向側には、ベース底面９０が配置される。ベース底面９０は、枠形形状を有しており、中央部分には底面開口９２が配置される。また、ベース底面９０のｙ軸方向の両端部分のそれぞれには２つの固定孔９４が設けられる。 Next, the configuration of the support member 14 will be described, but in order to clarify the description, FIG. 6 is also used in addition to the drawings so far. FIG. 6 is a perspective view showing the configuration of the base 30. The bottom surface 90 of the base is arranged on the negative side of the z-axis of the base 30. The base bottom surface 90 has a frame shape, and a bottom surface opening 92 is arranged in the central portion. Further, two fixing holes 94 are provided at both ends of the base bottom surface 90 in the y-axis direction.

このようなベース底面９０のｚ軸の負方向側に、底面カバー１１０が配置される。底面カバー１１０は、ベース底面９０に着脱可能な矩形状のカバーであり、ベース底面９０の外周に合わせたサイズを有する。ベース底面９０に底面カバー１１０が取り付けられることによって、底面開口９２が塞がれる。この取付のために底面カバー１１０のｙ軸方向の両端部分のそれぞれには２つの固定部１１２が設けられる。固定部１１２は、ｚ軸方向の貫通孔であり、ベース底面９０の固定孔９４に対応した位置に配置される。 The bottom cover 110 is arranged on the negative side of the z-axis of the base bottom surface 90. The bottom cover 110 is a rectangular cover that can be attached to and detached from the base bottom surface 90, and has a size that matches the outer circumference of the base bottom surface 90. By attaching the bottom cover 110 to the bottom surface 90 of the base, the bottom opening 92 is closed. For this mounting, two fixing portions 112 are provided at both ends of the bottom cover 110 in the y-axis direction. The fixing portion 112 is a through hole in the z-axis direction, and is arranged at a position corresponding to the fixing hole 94 on the bottom surface 90 of the base.

支持部材１４は、前述のごとく、矩形箱形の形状を有する。支持部材１４のｚ軸の正方向側の面には、ｘ軸方向に延びる溝部１２０が形成される。溝部１２０には、固定ネジ１２２の頭部が嵌合されており、固定ネジ１２２の胴部がｚ軸の正方向に突出する。ここで、２つの固定ネジ１２２が１つの溝部１２０に配置される。 As described above, the support member 14 has a rectangular box shape. A groove 120 extending in the x-axis direction is formed on the surface of the support member 14 on the positive direction side of the z-axis. The head portion of the fixing screw 122 is fitted in the groove portion 120, and the body portion of the fixing screw 122 projects in the positive direction of the z-axis. Here, two fixing screws 122 are arranged in one groove 120.

底面カバー１１０がベース３０から取り外された状態において、底面カバー１１０の固定部１１２に固定ネジ１２２が挿入可能な位置に、支持部材１４が配置される。つまり、底面カバー１１０の固定部１１２をもとに、複数の支持部材１４のそれぞれを配置すべき位置が決定される。このように、底面カバー１１０は、複数の支持部材１４の位置合わせに使用される。また、複数の支持部材１４の位置が決定した後、底面カバー１１０の固定部１１２に固定ネジ１２２がｚ軸の負方向側から挿入されることによって、複数の支持部材１４は、固定部１１２に取り付けられる。さらに、固定部１１２に複数の支持部材１４のそれぞれを取り付けた状態において、ベース３０の固定孔９４に固定ネジ１２２がｚ軸の負方向側から挿入されることによって、底面カバー１１０は、ベース底面９０に取り付けられる。特に、底面カバー１１０の固定部１１２を介して、複数の支持部材１４と筐体１０のベース底面９０とが連結される。このように、複数の支持部材１４は、底面カバー１１０に固定されることによって、筐体１０を下方から支持する。 With the bottom cover 110 removed from the base 30, the support member 14 is arranged at a position where the fixing screw 122 can be inserted into the fixing portion 112 of the bottom cover 110. That is, the position where each of the plurality of support members 14 should be arranged is determined based on the fixing portion 112 of the bottom cover 110. In this way, the bottom cover 110 is used for aligning the plurality of support members 14. Further, after the positions of the plurality of support members 14 are determined, the fixing screws 122 are inserted into the fixing portions 112 of the bottom cover 110 from the negative direction side of the z-axis, so that the plurality of supporting members 14 are connected to the fixing portions 112. It is attached. Further, in a state where each of the plurality of support members 14 is attached to the fixing portion 112, the fixing screw 122 is inserted into the fixing hole 94 of the base 30 from the negative direction side of the z-axis, so that the bottom cover 110 is formed on the bottom surface of the base. Attached to 90. In particular, the plurality of support members 14 and the base bottom surface 90 of the housing 10 are connected via the fixing portion 112 of the bottom cover 110. In this way, the plurality of support members 14 support the housing 10 from below by being fixed to the bottom cover 110.

（２）転倒防止部材１６、本体２０の構成
図７は、転倒防止部材１６、本体２０の構成を示す分解斜視図である。本体ボディ２２の本体開口部２６の縁から外側に向かって鍔部１８２が形成される。また、鍔部１８２のｘ軸の負方向側に対向して壁部１８０が配置される。壁部１８０と鍔部１８２は、溝形状によって連続される。この溝形状は、本体開口部２６を囲むように全周にわたって形成されており、本体カバー２４の外縁部が鍔部１８２に重ねられる。このような状態において、本体カバー２４は、ネジによって、本体開口部２６を覆うように本体ボディ２２に取り付けられる。また、鍔部１８２のｙ軸方向の中央部分において、取付片１８４がｚ軸の正方向に突出する。取付片１８４のｙ軸方向の両端のそれぞれには、固定孔１８６が形成される。 (2) Configuration of Fall Prevention Member 16 and Main Body 20 FIG. 7 is an exploded perspective view showing the configuration of the fall prevention member 16 and the main body 20. A collar portion 182 is formed from the edge of the main body opening 26 of the main body 22 toward the outside. Further, the wall portion 180 is arranged so as to face the negative direction side of the x-axis of the collar portion 182. The wall portion 180 and the flange portion 182 are continuous by a groove shape. This groove shape is formed over the entire circumference so as to surround the main body opening 26, and the outer edge portion of the main body cover 24 is overlapped with the flange portion 182. In such a state, the main body cover 24 is attached to the main body body 22 by a screw so as to cover the main body opening 26. Further, at the central portion of the collar portion 182 in the y-axis direction, the mounting piece 184 projects in the positive direction of the z-axis. Fixing holes 186 are formed at both ends of the mounting piece 184 in the y-axis direction.

転倒防止部材１６は、第１固定部１５０、第２固定部１５２を含む。第１固定部１５０は、第１分割片１５６、第１片１５８、固定片１６０、第２片１６２を含んでおり、これらは一体的に形成される。第１分割片１５６は、本体ボディ２２のｚ軸の正方向側に配置された面に沿って略矩形板状に形成される。また、第１分割片１５６のｘ軸の負方向側において、ｙ軸方向の両端近傍のそれぞれに連結孔１７４が形成される。 The fall prevention member 16 includes a first fixing portion 150 and a second fixing portion 152. The first fixed portion 150 includes a first divided piece 156, a first piece 158, a fixed piece 160, and a second piece 162, which are integrally formed. The first divided piece 156 is formed in a substantially rectangular plate shape along a surface of the main body 22 arranged on the positive side of the z-axis. Further, on the negative side of the x-axis of the first partition piece 156, connecting holes 174 are formed in the vicinity of both ends in the y-axis direction.

第１片１５８は、第１分割片１５６のｘ軸の正方向側端からｚ軸の負方向に突出した矩形板状に形成され、ｘ軸の負方向側の面が本体ボディ２２の壁部１８０に接触する。固定片１６０は、矩形板状に形成され、ｘ軸の正方向側の面が取付片１８４に接触する。第２片１６２は、第１片１５８のｚ軸の負方向側端と固定片１６０のｚ軸の負方向側端とを連続させる。このように第１片１５８、固定片１６０、第２片１６２の断面はＵ字状に形成され、本体ボディ２２の溝形状の内側に密着する。固定片１６０のｙ軸方向の両端近傍のそれぞれには、固定孔１６６が形成される。取付片１８４に形成された固定孔１８６を介して固定ネジ１８８が固定孔１６６に結合されることによって、固定片１６０が本体ボディ２２に固定される。 The first piece 158 is formed in the shape of a rectangular plate protruding from the positive side end of the x-axis of the first divided piece 156 in the negative direction of the z-axis, and the surface on the negative side of the x-axis is the wall portion of the main body 22. Contact 180. The fixed piece 160 is formed in a rectangular plate shape, and the surface on the positive direction side of the x-axis comes into contact with the mounting piece 184. The second piece 162 connects the negative end of the first piece 158 on the z-axis and the negative end of the fixed piece 160 on the z-axis. In this way, the cross sections of the first piece 158, the fixed piece 160, and the second piece 162 are formed in a U shape, and are in close contact with the inside of the groove shape of the main body 22. Fixing holes 166 are formed in the vicinity of both ends of the fixing piece 160 in the y-axis direction. The fixing piece 160 is fixed to the main body 22 by connecting the fixing screw 188 to the fixing hole 166 via the fixing hole 186 formed in the mounting piece 184.

第２固定部１５２は、固定面１５４と第２分割片１６４とを含んでおり、Ｌ字状に形成される。固定面１５４は矩形板状に形成され、ｚ軸の正方向端近傍に複数の固定孔１７２が配置される。複数の固定孔１７２を介して固定ネジ（図示せず）が建物壁６の壁に結合されることによって、第２固定部１５２が建物壁６に固定される。第２固定部１５２のｚ軸の負方向側端からｘ軸の正方向に第２分割片１６４が延びる。第２分割片１６４は、第１分割片１５６の上に重ね合わされる矩形板状に形成される。第２分割片１６４のｙ軸方向の両端近傍のそれぞれには連結孔１６８が配置される。連結孔１６８は、ｘ軸方向に長いスリット状に形成される。第２分割片１６４に形成された連結孔１６８を介して、第１分割片１５６に形成された連結孔１７４に連結ネジ１７０が結合されることによって、第１分割片１５６と第２分割片１６４とが連結される。これは、第１固定部１５０と第２固定部１５２とが連結されることに相当する。 The second fixing portion 152 includes a fixing surface 154 and a second divided piece 164, and is formed in an L shape. The fixing surface 154 is formed in a rectangular plate shape, and a plurality of fixing holes 172 are arranged in the vicinity of the positive end of the z-axis. The second fixing portion 152 is fixed to the building wall 6 by connecting the fixing screws (not shown) to the wall of the building wall 6 through the plurality of fixing holes 172. The second divided piece 164 extends in the positive direction of the x-axis from the negative end of the second fixed portion 152 in the z-axis. The second divided piece 164 is formed in a rectangular plate shape overlaid on the first divided piece 156. Connecting holes 168 are arranged in the vicinity of both ends of the second dividing piece 164 in the y-axis direction. The connecting hole 168 is formed in a slit shape long in the x-axis direction. The first dividing piece 156 and the second dividing piece 164 are formed by connecting the connecting screw 170 to the connecting hole 174 formed in the first dividing piece 156 through the connecting hole 168 formed in the second dividing piece 164. And are concatenated. This corresponds to connecting the first fixing portion 150 and the second fixing portion 152.

前述のごとく、転倒防止部材１６は、金属製の板材で形成されるが、ｚ軸方向に撓みやすい板材である方が好ましい。これは、転倒防止部材１６によって本体２０が建物壁６に固定された状態において、土壌の陥没等により、筐体１０がｚ軸の負方向に沈んだ場合に、その変化に転倒防止部材１６を追従させるためである。これにより、建物壁６に加わる荷重も低減される。 As described above, the fall prevention member 16 is made of a metal plate material, but it is preferable that the plate material is easily bent in the z-axis direction. This is because when the main body 20 is fixed to the building wall 6 by the fall prevention member 16 and the housing 10 sinks in the negative direction of the z-axis due to the sinking of soil or the like, the fall prevention member 16 is changed. This is to make it follow. As a result, the load applied to the building wall 6 is also reduced.

前述のごとく、連結ネジ１７０が通される連結孔１６８は、ｘ軸方向に長いスリット状形成されている。したがって、転倒防止部材１６は、連結孔１６８の範囲内において、ｘ軸方向に伸縮可能であり、固定面１５４と固定片１６０との距離を５０ｍｍ〜１２０ｍｍの間で任意に調節することができる。つまり、転倒防止部材１６によって、本体２０と建物壁６との距離は連続的に調節可能である。一方、固定部材１２では、第２分割片６０に設けられた複数の組合せのいずれかを選択することによって、第１固定面５４と第２固定面５８との距離が７５ｍｍあるいは１００ｍｍに調節される。つまり、固定部材１２によって、ベース３０と基礎部分４との距離は離散的に調節可能である。 As described above, the connecting hole 168 through which the connecting screw 170 is passed is formed in the shape of a long slit in the x-axis direction. Therefore, the fall prevention member 16 can be expanded and contracted in the x-axis direction within the range of the connecting hole 168, and the distance between the fixing surface 154 and the fixing piece 160 can be arbitrarily adjusted between 50 mm and 120 mm. That is, the distance between the main body 20 and the building wall 6 can be continuously adjusted by the fall prevention member 16. On the other hand, in the fixing member 12, the distance between the first fixed surface 54 and the second fixed surface 58 is adjusted to 75 mm or 100 mm by selecting any of a plurality of combinations provided in the second divided piece 60. .. That is, the distance between the base 30 and the foundation portion 4 can be adjusted discretely by the fixing member 12.

（３）電気設備１００の固定方法
図８（ａ）−（ｄ）は、電気設備１００の固定手順を示す。図８（ａ）では、電気設備１００を設置すべき場所が設定されると、その場所の地均しがなされるとともに、その場所に支持部材１４が置かれる。支持部材１４の溝部１２０に固定ネジ１２２が挿入されてから、底面カバー１１０の固定部１１２に固定ネジ１２２が通されることによって、底面カバー１１０が支持部材１４に取り付けられる。これは、底面カバー１１０をベース３０から取り外した状態において、底面カバー１１０の固定部１１２に合わせた位置に、複数の支持部材１４のそれぞれを配置してから、配置した複数の支持部材１４のそれぞれに固定部１１２を取り付けることに相当する。 (3) Fixing Method of Electrical Equipment 100 FIGS. 8A-(d) show a procedure for fixing the electrical equipment 100. In FIG. 8A, when a place where the electrical equipment 100 should be installed is set, the place is leveled and the support member 14 is placed at the place. After the fixing screw 122 is inserted into the groove 120 of the support member 14, the bottom cover 110 is attached to the support member 14 by passing the fixing screw 122 through the fixing portion 112 of the bottom cover 110. This is because, in a state where the bottom cover 110 is removed from the base 30, each of the plurality of support members 14 is arranged at a position aligned with the fixed portion 112 of the bottom cover 110, and then each of the arranged support members 14 is arranged. Corresponds to attaching the fixing portion 112 to the.
