Abstract
Description
本発明は、配電盤や制御盤などのキャビネットに関する。 The present invention relates to a cabinet such as a switchboard or a control panel.
配電盤キャビネットは、角パイプ状の３本の金属製枠材を互いに直交させて連結した三角錘状の角部を上下４隅に有する平行六面体（直方体）枠構造を基本構造としており、この平行六面体枠構造における枠材間の連結は、枠材同士を溶接するか、専用の連結具を使用して溶接レスで連結するかで行われている。各枠材を互いに直交させて枠材同士を直接に溶接したキャビネットは、溶接設備を有する工場で製造され、塗装および梱包されて現場へと出荷される。このようなキャビネットは高度な溶接作業を必要とするため生産コストが高くなると共に、嵩張る平行六面体枠に溶接した後で塗装するために塗装設備が大掛かりとなり、また、嵩張るキャビネットの梱包費や保管費、運搬費が高く付く不具合がある。 The switchboard cabinet is based on a parallel hexahedron (rectangular) frame structure with triangular pyramid corners at the top and bottom four corners connected by three rectangular pipe-shaped metal frame members orthogonal to each other. The connection between the frame members in the frame structure is performed by welding the frame members or connecting them without using a dedicated connector. A cabinet in which the frame members are orthogonally crossed and directly welded to each other is manufactured at a factory having a welding facility, painted and packed, and shipped to the site. Such cabinets require high-level welding work, resulting in high production costs, large coating equipment for painting after welding to the bulky parallelepiped frame, and packing and storage costs for bulky cabinets. There is a problem that the transportation cost is high.
溶接レスで枠材同士を連結するキャビネットは、角継手やコーナープレートなどと称される連結具（例えば、特許文献１参照）を使用したものが一般的であり、その概要を図１３に示すと、同図のキャビネット５０は、計４本の角パイプ状の柱部材である枠材５１と、計８本の角パイプ状の梁部材である枠材５１で平行六面体枠を構築し、計８頂点の角部５２に３個ずつの連結具５３を使用している。１つの角部５２は互いに直交する３本の枠材５１を三角錐状に連接した部所で、１つの角部５２の２本ずつの枠材５１で形成される計３箇所のコーナー部分に１個ずつの連結具５３を固着している。連結具５３は、図１４に示すような直角二等辺三角形の金属製コーナープレートで、直交する二辺の取付板部５４が対応する枠材５１の平坦な取付面に接合されて、図示しないボルトで連結される。取付板部５４には、例えば横一列に複数の取付穴５５が形成され、この取付穴５５にボルトが挿通されて対応する枠材５１に締結される。１つの連結具５３で直交する２本の枠材５１の端部同士が連結される。
図１３のキャビネットは、枠材に連結具をボルト止めする簡単な作業で製造組立が行え、枠材を個々に塗装してから連結具で連結することができるために小規模な塗装設備が適用できる利点があり、枠材を個々に梱包し出荷して現場で組立ができる有利さがある。しかし、平行六面体枠のキャビネットの１つの三角錐状角部を構築するのに連結具が３個必要であり、計８角部を有するキャビネットにおいては２４個と多くの連結具が必要で、結果的に製作費が高くなる。また、三角錐状角部を構築する３個一組の連結具の各々が互いに直交する方向性で枠材にボルト止めされているため、３個一組の連結具のいずれか１つに吊り荷重などの荷重が加わると、方向性の異なる他の連結具の固定ボルトに軸方向の引張り力が作用し、さらに連結具の板厚方向に曲げ力が作用して連結具が変形しやすくなり、三角錐状角部を強度的に安定させることが難しい。 The cabinet shown in FIG. 13 can be manufactured and assembled by a simple operation of bolting the connector to the frame material. Since the frame material can be individually coated and then connected by the connector, a small-scale painting facility is applied. There is an advantage that the frame material can be individually packed and shipped and assembled on site. However, three connecting tools are required to construct one triangular pyramid corner of a parallelepiped frame cabinet, and 24 connecting tools are required in a cabinet having a total of eight corners. The production cost increases. In addition, since each of the set of three connecting tools constituting the triangular pyramid corner is bolted to the frame member in a direction orthogonal to each other, it is suspended on any one of the three connecting tools. When a load such as a load is applied, the tensile force in the axial direction acts on the fixing bolts of other coupling devices with different directions, and the bending force acts in the plate thickness direction of the coupling device, making the coupling device more easily deformed. It is difficult to stabilize the triangular pyramid corner in strength.
本発明の目的とするところは、制作費の低減が容易で、強度的に安定した信頼性の高い配電盤などのキャビネットを提供することにある。 An object of the present invention is to provide a cabinet such as a distribution board that is easy to reduce production costs, is stable in strength, and has high reliability.
本発明は上記目的を達成するため、３本の第１枠材、第２枠材、第３枠材を互いに直交させて連接した角部を有する枠状キャビネットにおいて、次の１つの連結金具で３本の第１枠材、第２枠材、第３枠材を連結して三角錐状の角部を構築したことを特徴とする。連結金具は、第１枠材と第２枠材の同一平面に沿うそれぞれの取付面に接合された両端部を有する平板状の第１取付板部と、第１枠材と第３枠材の同一平面に沿うそれぞれの取付面に接合された両端部を有する平板状の第２取付板部と、第１取付板部と第２取付板部を連結して一体化する連結部とを有し、この１つの連結金具で３本の枠材を連結する。 In order to achieve the above object, the present invention provides a frame-shaped cabinet having corner portions in which three first frame members, second frame members, and third frame members are connected to each other at right angles, and the following one connecting fitting is used. A triangular pyramid-shaped corner is constructed by connecting three first frame members, second frame members, and third frame members. The connecting bracket includes a flat plate-like first attachment plate portion having both ends joined to respective attachment surfaces along the same plane of the first frame member and the second frame member, and the first frame member and the third frame member. A flat plate-like second mounting plate portion having both ends joined to respective mounting surfaces along the same plane, and a connecting portion for connecting and integrating the first mounting plate portion and the second mounting plate portion. The three frame members are connected by this one connecting metal fitting.
ここで、枠状キャビネットは、配電盤や制御盤などの電気キャビネットのほか、スチールラック構造のキャビネットが適用可能である。また、連結金具は、１枚の金属板を折り曲げ成形した一枚板物の製品や、第１取付板部と第２取付板部を別々に製作してこの二枚を金属板や金属棒などの別部品の連結部材で連結した組立製品、または、第１取付板部と連結部を一体に有する一枚板物に別体の第２取付板部を連結した組立製品が適用できる。これら連結金具は大量生産容易で安価なものが提供でき、キャビネットの溶接レスの製造組立を可能にすることから、枠材に塗装材が適用できる。 Here, as the frame-like cabinet, a steel rack structure cabinet can be applied in addition to an electrical cabinet such as a switchboard or a control panel. In addition, the connecting bracket is a single plate product obtained by bending one metal plate, the first mounting plate portion and the second mounting plate portion are separately manufactured, and the two plates are metal plates, metal bars, etc. An assembly product connected by a connecting member of another part, or an assembly product in which a separate second mounting plate portion is connected to a single plate having the first mounting plate portion and the connecting portion integrally can be applied. These connecting fittings can be easily mass-produced and can be provided at low cost, and can be manufactured and assembled without the cabinet being welded. Therefore, a coating material can be applied to the frame material.
また、連結金具は、１つで３本の枠材を互いに直交させた状態で連結してキャビネットの三角錐状の角部を構築する。角部は、平行六面体枠の８頂点の角部のほか、１本の枠材の中間箇所に２本の枠材の端部を直交させた角部である。１つのキャビネットの複数全ての角部、或いは、一部の角部を除く選択された角部に連結金具が使用できる。枠材は、ねじ穴などの穴を有するものがキャビネット組立上に便利であり、この枠材の穴を利用して連結金具をボルトなどで固定する。ボルト止めする場合は、ボルトを枠材に形成したねじ穴に螺合させる、或いは、ナットを使用することで行うことができる。枠材は、角パイプ状や円パイプ状の金属管以外に、山形鋼タイプやみぞ形鋼タイプの骨材が適用できる。キャビネットにおける１つの角部の３本の枠材を三角錐状に連結する１つの連結金具は、１つの角部に従来３個使用していた連結具の機能を備え、換言すれば従来３個の連結具が１つの連結金具に代用されて、連結具の使用数を１／３に低減させ、その分、キャビネットの制作費が安くなる。また、互いに直交する３本の枠材を連結する１つの連結金具の第１・第２取付板部のそれぞれを２本の枠材にボルトで連結すると、連結金具の連結部を介して各取付板部に加わる荷重の方向がボルト軸方向と直交する方向となり、この方向はボルト止め強度の最も大きなボルト剪断方向となって、連結金具が荷重で変形し難くくなり、連結金具による枠材連結強度が高い値で安定する。 In addition, one connecting bracket connects three frame members in a state of being orthogonal to each other, thereby constructing a triangular pyramid corner of the cabinet. In addition to the corners at the eight apexes of the parallelepiped frame, the corners are corners in which the end portions of the two frame members are orthogonal to an intermediate position of one frame member. Connecting metal fittings can be used at all corners of a single cabinet, or at selected corners excluding some corners. A frame member having a hole such as a screw hole is convenient for assembling the cabinet, and the connecting bracket is fixed with a bolt or the like using the hole of the frame member. In the case of bolting, the bolt can be screwed into a screw hole formed in the frame member, or a nut can be used. As the frame material, in addition to a square pipe-shaped or circular pipe-shaped metal pipe, an angle steel type or a grooved steel type aggregate can be applied. One connecting bracket that connects three frame members at one corner in a cabinet in a triangular pyramid shape has the function of a connector that has been used three times at one corner, in other words, three in the past. The connecting tool is replaced with one connecting bracket, so that the number of connecting tools used is reduced to 1/3, and the production cost of the cabinet is reduced accordingly. Further, when each of the first and second mounting plate portions of one connecting bracket for connecting three frame members orthogonal to each other is connected to the two frame members with bolts, each mounting is performed via the connecting portion of the connecting bracket. The direction of the load applied to the plate part is the direction orthogonal to the bolt axis direction, and this direction is the bolt shearing direction with the largest bolting strength, making it difficult for the fittings to be deformed by the load, and connecting the frame material by the fittings Stable at high strength.
また、１つのキャビネットの複数ある角部の一部の角部を除く選択された角部にのみ連結金具を使用する場合、連結金具を使用しない角部に別の直角専用コーナー金具を使用することができる。コーナー金具は、直交する２本の枠材の直角コーナー部分に装着する金具で、２本の枠材の互いに直交して対向するそれぞれの内側取付面に接合してボルトなどで固定される内側取付板部と、２本の枠材の側面にあって同一平面で互いに直交するそれぞれの取付面に接合してボルトなどで固定される側面取付板部と、これら内側取付板部と側面取付板部を連結一体化する連結部を有する構造とすることができる。このようなコーナー金具は、キャビネットの枠材を追加して枠組構造を変更するといった際に有効である。 In addition, when using connecting brackets only for selected corners except for some corners of multiple corners of one cabinet, use another right-angle corner bracket for corners that do not use connecting brackets. Can do. A corner bracket is a bracket that is attached to a right-angled corner of two orthogonal frame members, and is attached to the inner attachment surfaces of the two frame members that are orthogonal to each other and fixed with bolts or the like. A plate portion, side attachment plates on the side surfaces of the two frame members, joined to respective attachment surfaces that are orthogonal to each other in the same plane, and fixed with bolts, etc., and these inner attachment plate portions and side attachment plate portions It can be set as the structure which has a connection part which connects and integrates. Such a corner metal fitting is effective when the frame structure is changed by adding a frame material of the cabinet.
本発明においては、取付金具の第１取付板部の第１枠材と接合する端部と、第２取付板部の第１枠材と接合する端部とが互いに直交方向で交差して、これら各端部が相手側取付板部の外面より張出す構造とすることができる。つまり、第１取付板部と第２取付板部が共に平板で互いに直交する配置関係にあるため、第１枠材と接合する両者の端部同士を直交させて交差させ、この各端部を互いに交差する箇所から張り出す構造とする。この場合、各取付板部の互いに交差する端部の形状は１枚の矩形歯形状、数枚の櫛歯形状と任意であり、各々の端部の根元同士を係止させた状態で交差させるようにすると、両端部同士が補強し合って連結金具自体の強度が増す。 In the present invention, the end portion of the first mounting plate portion of the mounting bracket that joins the first frame member and the end portion of the second mounting plate portion that joins the first frame member intersect each other in the orthogonal direction, It can be set as the structure where these each edge part protrudes from the outer surface of the other party mounting plate part. That is, since the first mounting plate portion and the second mounting plate portion are both flat and orthogonal to each other, both ends joined to the first frame member are orthogonally intersected, and each end is A structure that protrudes from the intersections. In this case, the shape of the end portions of each mounting plate portion that intersect each other is arbitrarily selected from one rectangular tooth shape and several comb tooth shapes, and the ends of each end portion are crossed in a locked state. If it does so, both ends will mutually reinforce and the intensity | strength of connection metal fitting itself will increase.
また、本発明においては、取付金具の第１取付板部と第２取付板部を共に略Ｌ形平板とすることができる。つまり、第１取付板部は、第２枠材の取付面と接合する平板状の端部から第１枠材の長さ方向に延在して第１枠材の取付面までＬ形に突出する張出端部を有する略Ｌ形平板であり、第２取付板部は、第３枠材の取付面と接合する平板状の端部から第１枠材の長さ方向に延在して第１枠材の取付面までＬ形に突出する張出端部を有する略Ｌ形平板とすることができる。この場合、共に略Ｌ形平板の第１取付板部と第２取付板部の長さが相違して、各々の張出端部が根元同士で直交して交差し、両張出端部が第１枠材に接合して固定される。 In the present invention, both the first mounting plate portion and the second mounting plate portion of the mounting bracket can be substantially L-shaped flat plates. In other words, the first mounting plate portion extends in the length direction of the first frame member from the flat end joined to the mounting surface of the second frame member and protrudes in an L shape to the mounting surface of the first frame member. The second mounting plate portion extends in the length direction of the first frame member from the flat end joined to the mounting surface of the third frame member. It can be set as the substantially L-shaped flat plate which has the overhang | projection edge part which protrudes in L shape to the attachment surface of a 1st frame material. In this case, the lengths of the first mounting plate portion and the second mounting plate portion, both of which are substantially L-shaped flat plates, are different, and the overhanging end portions intersect perpendicularly at the roots, and the overhanging end portions are The first frame member is joined and fixed.
さらに、本発明においては、第１取付板部を上記同様に略Ｌ形平板とし、第２取付板部を第３枠材と接合する平板状の端部とこの端部から第３枠材の長さ方向に延在する張出端部を有する略Ｉ形平板とすることができる。この場合、第２取付板部の張出端部を第２枠材の端面と第１枠材の間に介挿することができる。第２取付板部を略Ｉ形平板とすることで、取付金具を小形化することができる。また、第２取付板部の張出端部を第２枠材の端面と第１枠材の間に介挿することで、キャビネット角部における取付金具の露呈部分の面積を低減させることができる。 Furthermore, in the present invention, the first mounting plate portion is a substantially L-shaped flat plate as described above, and the plate-like end portion that joins the second mounting plate portion to the third frame member and the third frame member from the end portion. It can be set as the substantially I-shaped flat plate which has the overhang | projection edge part extended in a length direction. In this case, the overhanging end portion of the second mounting plate portion can be interposed between the end surface of the second frame member and the first frame member. By making the second mounting plate portion a substantially I-shaped flat plate, the mounting bracket can be miniaturized. Moreover, the area of the exposed portion of the mounting bracket at the corner portion of the cabinet can be reduced by inserting the protruding end portion of the second mounting plate portion between the end surface of the second frame member and the first frame member. .
本発明においては、連結金具の連結部が第２枠材と第３枠材の直交するそれぞれの取付面に沿う直交二辺を有する平板状で、第１取付板部と第２取付板部が連結部の直交二辺から同一側に略直角に折曲した延在部分である構造とすることができる。この場合の連結金具は、１枚の金属板の２箇所を同じ山折りした一枚板物で、大量生産が容易で単価を安くすることができる。また、一枚板物は強度が安定しており、連結具としての取扱いが容易で、枠材への連結作業が簡単になる。 In this invention, the connection part of a connection metal fitting is a flat form which has two orthogonal sides along each attachment surface to which a 2nd frame material and a 3rd frame material orthogonally cross, and a 1st attachment plate part and a 2nd attachment plate part are It can be set as the structure which is the extension part bent at the substantially right angle from the two orthogonal | vertical sides of a connection part to the same side. In this case, the connecting metal fitting is a single plate that is obtained by folding two portions of one metal plate into the same mountain, and mass production is easy and the unit price can be reduced. In addition, the single plate has a stable strength, is easy to handle as a connector, and can be easily connected to the frame material.
また、本発明においては、３本の枠材の内の第１枠材が略鉛直な柱部材、第２枠材と第３枠材が略水平な梁部材である平行六面体キャビネットの８頂点全ての角部に連結金具を配備することができる。この場合の平行六面体キャビネットは立方体を含む直立した直方体で、最下段の４頂点に４角部があり、最上段の４頂点に４角部があって、これら全ての角部に１つずつ連結金具を使用することで、強度的に安定したキャビネットが構築できる。 Further, in the present invention, all eight vertices of the parallelepiped cabinet in which the first frame member of the three frame members is a substantially vertical column member, and the second frame member and the third frame member are substantially horizontal beam members. Connecting metal fittings can be provided at the corners. The parallelepiped cabinet in this case is an upright rectangular parallelepiped including a cube, with four corners at the bottom four vertices and four corners at the top four vertices, one connected to all these corners. By using metal fittings, a stable cabinet can be constructed.
このような平行六面体キャビネットに使用される連結金具においては、その連結部を直角二等辺三角形の平板状にして、連結部の一部にキャビネット全体を吊り下げるなどの用途に適合したキャビネット支持手段を設けることができる。例えば、平行六面体キャビネットの最上段の角部に使用する連結金具においては、その連結部に吊りボルトの取付穴を形成し、この取付穴に吊りボルトを締結させ、吊りボルトにワイヤを引掛けてキャビネットを吊り下げることができる。また、平行六面体キャビネットの最下段の角部に使用する連結金具においては、その連結部にアンカーボルトの取付穴を形成し、この取付穴にアンカーボルトを挿通してナット止めすることで、キャビネットをアンカーボルトに位置決め固定することができる。 In the connecting metal fitting used in such a parallelepiped cabinet, the connecting part is formed into a right-angled isosceles triangular flat plate shape, and a cabinet support means suitable for applications such as hanging the entire cabinet on a part of the connecting part is provided. Can be provided. For example, in a connection fitting used for the uppermost corner of a parallelepiped cabinet, a suspension bolt mounting hole is formed in the connection portion, a suspension bolt is fastened to this attachment hole, and a wire is hooked on the suspension bolt. The cabinet can be hung. In addition, in the connecting bracket used at the lowermost corner of the parallelepiped cabinet, an anchor bolt mounting hole is formed in the connecting portion, and the anchor bolt is inserted into this mounting hole and secured with a nut. It can be positioned and fixed to the anchor bolt.
このような連結金具の連結部に形成する取付穴は、吊りボルトとアンカーボルトのいずれの挿通にも共用できる。また、連結金具の連結部に取付穴のようなキャビネット支持手段を設ける場合、連結部の一辺を板厚方向に折曲したリブ部で連結部自体の強度を増大させて、キャビネット支持強度を安定させることができる。また、平行六面体キャビネットの角部を構築する連結金具の連結部外面を枠材外面と面一にして、連結部外面を平行六面体キャビネットの六面の一部として利用することができる。 The attachment hole formed in the connection part of such a connection metal fitting can be shared by both insertion of the suspension bolt and the anchor bolt. In addition, when providing cabinet support means such as mounting holes in the connection part of the connection bracket, the strength of the connection part itself is increased by a rib part that is bent in one side of the connection part in the thickness direction, thereby stabilizing the cabinet support strength. Can be made. Moreover, the connection part outer surface of the connection metal fitting which comprises the corner | angular part of a parallelepiped cabinet can be flush | level with the frame material outer surface, and a connection part outer surface can be utilized as a part of six surfaces of a parallelepiped cabinet.
本発明によれば、３本の枠材を互いに直交させて三角錐状に連結して角部を構築する連結金具が１つの角部に対して最少数の１つで済むので、枠材同士をボルトなどで連結する連結金具の使用数を大幅に低減させることが可能となり、連結金具によるキャビネット価格の低減ができると共に、１つのキャビネットの複数の角部に同一種類の連結金具が使用できて連結金具の保守管理が容易となる実用上に優れた効果がある。 According to the present invention, the frame members are formed by connecting the three frame members orthogonally to each other in a triangular pyramid shape so that a corner piece is formed with a minimum number of one for each corner portion. It is possible to greatly reduce the number of connecting brackets used to connect the brackets with bolts, etc., and the cabinet price can be reduced by connecting brackets, and the same type of connecting bracket can be used at multiple corners of one cabinet. There is an excellent practical effect that facilitates the maintenance and management of the connecting bracket.
また、連結金具を１枚の金属板を折曲加工した一枚板物として製造することで、連結金具のより一層の単価低減が図れる。さらに、枠材に直接的に接合して連結される第１、第２取付板部が互いに直交する平板状で、各々を直交する２本ずつの枠材にボルト止めなどで固定するので、連結金具の連結部に加わる荷重は各取付板部の面と平行な方向に作用して、枠材との取付強度を常に高く設定することができ、強度的に高く安定したキャビネットが構築できる効果がある。 Moreover, the unit price of the connection fitting can be further reduced by manufacturing the connection fitting as a single-sheet product obtained by bending one metal plate. In addition, the first and second mounting plate parts that are directly joined and connected to the frame member are flat plate shapes that are orthogonal to each other, and are fixed to two orthogonal frame members by bolting or the like. The load applied to the connecting part of the metal fitting acts in the direction parallel to the surface of each mounting plate part, so that the mounting strength with the frame material can always be set high, and there is an effect that a strong and stable cabinet can be constructed. is there.

It has a substantially trapezoidal intermediate portion 5b-1 extending to the opposite side, and an overhanging end portion 5c-1 protruding in an L shape from the inner side of the tip portion of the intermediate portion 5b-1. A plurality of mounting holes 6a are formed at equal intervals in the lateral direction in FIG. 5 at the bent base end portion 5a-1, and a plurality of mounting holes 6b are formed at equal intervals in the vertical direction at the protruding end portion 5c-1. . The second mounting plate portion 5-2 includes an end portion (hereinafter referred to as a bent base end portion) 5a-2 along the connecting portion 5-3, and a connecting portion 5-3 from the bent base end portion 5a-2. It has a substantially triangular intermediate portion 5b-2 extending to the opposite side, and an overhanging end portion 5c-2 protruding in an L shape from the distal end side of the intermediate portion 5b-2. In FIG. 5, a plurality of mounting holes 7a are formed at equal intervals in the vertical direction, and a plurality of mounting holes 7b are formed at equal intervals in the lateral direction at the overhanging end 5c-2. A mounting hole 8 for attaching an external member such as a suspension bolt (see FIG. 6) is formed in the approximate center of the connecting portion 5-3 as required.
図４に示すように、連結部５−３の直交二辺から各取付板部５−１、５−２を略直角に山折りすると、第２取付板部５−２の張出端部５ｃ−２の根元部分が第１取付板部５−１の中間部５ｂ−１の側辺と直交して交差し、張出端部５ｃ−２が第１取付板部５−１の山折り側の外面から張り出す。また、第１取付板部５−１の張出端部５ｃ−１が第２取付板部５−２の張出端部５ｃ−２の図４で下方に突出して、両張出端部５ｃ−１、５ｃ−２が根元部分で直交して交差し、張出端部５ｃ−１が第２取付板部５−２の山折り側の外面から張り出す。２枚の平板状の各取付板部５−１、５−２が互いに直交して交差することで、両者が互いに補強し合い、枠材２への取付強度を安定させる。この補強効果は、両者の各張出端部５ｃ−１、５ｃ−２の根元部分同士を係止させて交差させることでより顕著となる。 As shown in FIG. 4, when the mounting plate portions 5-1 and 5-2 are mountain-folded at substantially right angles from two orthogonal sides of the connecting portion 5-3, the protruding end portion 5 c of the second mounting plate portion 5-2. -2 root portion intersects the side of the intermediate portion 5b-1 of the first mounting plate portion 5-1 at right angles, and the overhanging end portion 5c-2 is the mountain folding side of the first mounting plate portion 5-1.

The two flat plate-like attachment plate portions 5-1 and 5-2 intersect each other at right angles so that they reinforce each other and stabilize the attachment strength to the frame member 2. This reinforcing effect becomes more conspicuous by locking the base portions of the overhanging end portions 5c-1 and 5c-2 of the two to cross each other.
１つの角部Ｃの３本の枠材２と１つの連結金具５は、次の組付寸法関係にある。 The three frame members 2 at one corner C and the one connecting fitting 5 have the following assembly dimension relationship.
図２において、第１枠材２−１の一方の面Ｍ１と第２枠材２−２の内側面Ｎ１は同一平面上で互いに直交し、この両面Ｍ１、Ｎ１の各取付面１２、１２に第１取付板部５−１の両端部（折曲基端部５ａ−１と張出端部５ｃ−１）が接合される。この接合時に折曲基端部５ａ−１の取付穴６ａと第２枠材２−２の面Ｎ１の穴１１が合致し、張出端部５ｃ−１の取付穴６ｂが第１枠材２−１の面Ｍ１の穴１１に合致し、これら合致した穴に図３に示すようにボルト１０が挿通されて、第１取付板部５−１の両端部が第１枠材２−１と第２枠材２−２にボルト止めされる。この場合、穴１１はボルト１０と螺合するねじ穴で、ボルト１０は取付穴６ａ（６ｂ）に挿通されて穴１１に締結される。このボルト止めで、第１取付板部５−１が第１枠材２−１と第２枠材２−２の各端部を直交させて連結する。 In FIG. 2, one surface M1 of the first frame member 2-1 and the inner surface N1 of the second frame member 2-2 are orthogonal to each other on the same plane, and are attached to the mounting surfaces 12, 12 of the both surfaces M1, N1. Both end portions (the bent base end portion 5a-1 and the overhang end portion 5c-1) of the first mounting plate portion 5-1 are joined. At the time of joining, the mounting hole 6a of the bent base end portion 5a-1 and the hole 11 of the surface N1 of the second frame member 2-2 are matched, and the mounting hole 6b of the overhanging end portion 5c-1 is the first frame member 2. -1 matches the holes 11 of the surface M1, and the bolts 10 are inserted through these matched holes as shown in FIG. 3, and both ends of the first mounting plate portion 5-1 are connected to the first frame member 2-1. It is bolted to the second frame member 2-2. In this case, the hole 11 is a screw hole that is screwed into the bolt 10, and the bolt 10 is inserted into the attachment hole 6 a (6 b) and fastened to the hole 11. With this bolting, the first mounting plate portion 5-1 connects the end portions of the first frame member 2-1 and the second frame member 2-2 at right angles.
また、第１枠材２−１の他方の面Ｍ２と第３枠材２−３の内側面Ｎ１は同一平面上で互いに直交し、この両面Ｍ２、Ｎ１の各取付面１２、１２に第２取付板部５−２の両端部（折曲基端部５ａ−２と張出端部５ｃ−２）が接合される。この接合時に折曲基端部５ａ−２の取付穴７ａと第３枠材２−３の面Ｎ１の穴１１が合致し、張出端部５ｃ−２の取付穴７ｂが第１枠材２−１の面Ｍ２の穴１１に合致し、これら合致した穴にボルト１０が挿通されて、第２取付板部５−２の両端部が第１枠材２−１と第３枠材２−３にボルト止めされる。このボルト止めで、第２取付板部５−２が第１枠材２−１と第３枠材２−３の各端部を直交させて連結する。 Further, the other surface M2 of the first frame member 2-1 and the inner surface N1 of the third frame member 2-3 are orthogonal to each other on the same plane, and the second mounting surfaces 12 and 12 of the both surfaces M2 and N1 are second. Both end portions of the mounting plate portion 5-2 (the bent base end portion 5a-2 and the overhang end portion 5c-2) are joined. At the time of joining, the mounting hole 7a of the bent base end portion 5a-2 and the hole 11 of the surface N1 of the third frame member 2-3 are matched, and the mounting hole 7b of the overhanging end portion 5c-2 is the first frame member 2. -1 matches the hole 11 of the surface M2, and the bolts 10 are inserted through these matched holes, and both ends of the second mounting plate portion 5-2 are connected to the first frame member 2-1 and the third frame member 2-. Bolted to 3. With this bolting, the second mounting plate portion 5-2 connects the end portions of the first frame member 2-1 and the third frame member 2-3 so as to be orthogonal to each other.
また、連結金具５の直角二等辺三角形の連結部５−３は、その直交二辺が第２枠材２−２と第３枠材２−３の互いに直交して対向する内側面Ｎ１、Ｎ１に接合する。この接合時に連結部５−３の図３での上面は、第２枠材２−２と第３枠材２−３の上面と面一になる。連結部５−３の直交二辺から折曲された各取付板部５−１、５−２の折曲基端部５ａ−１、５ａ−２が第２枠材２−２と第３枠材２−３にボルト止めすることで、結果的に連結部５−３が第２枠材２−２と第３枠材２−３の各端部を直交させて連結する。 Further, the connecting portion 5-3 of the right angled isosceles triangle of the connecting metal 5 has inner surfaces N1 and N1 whose two orthogonal sides face each other perpendicularly to each other of the second frame member 2-2 and the third frame member 2-3. To join. At the time of this joining, the upper surface of the connecting portion 5-3 in FIG. 3 is flush with the upper surfaces of the second frame member 2-2 and the third frame member 2-3. The bent base end portions 5a-1 and 5a-2 of the mounting plate portions 5-1 and 5-2 bent from two orthogonal sides of the connecting portion 5-3 are the second frame member 2-2 and the third frame. By bolting to the material 2-3, as a result, the connection portion 5-3 connects the end portions of the second frame material 2-2 and the third frame material 2-3 so as to be orthogonal to each other.
図１のキャビネット１の計８箇所の角部Ｃに連結金具５は同じ取付け方をされる。したがって、図１のキャビネット１を上下逆にしても同じ形態であり、天地を問わないキャビネット１が構築される。また、キャビネット１を構築する計１２本の枠材２は塗装部材が適用できるので、塗装設備は個々の枠材２を塗装する小規模なものが適用できる。また、個々の枠材２を梱包し、搬送して現場でキャビネットに組立てることができるので、梱包費や輸送費の低減が可能となる。さらに、キャビネット１の構築に使用される連結金具５の数は、角部Ｃの数と同じ８個であり、必要最少数であるので、連結金具費の低減が可能となる。また、金属板を折曲した一枚板物の連結金具５は製造が簡単で量産でき、単価を低くすることができるので、連結金具費の尚一層の低減が可能となる。 The connecting fitting 5 is attached in the same manner to the corners C of the eight places in the cabinet 1 of FIG. Therefore, even if the cabinet 1 of FIG. 1 is turned upside down, it is the same form, and the cabinet 1 regardless of the top and bottom is constructed. Further, since a total of twelve frame members 2 constituting the cabinet 1 can be applied with coating members, a small-scale one for coating individual frame members 2 can be applied as a coating facility. In addition, since the individual frame members 2 can be packed, transported, and assembled into a cabinet at the site, the packaging cost and the transportation cost can be reduced. Furthermore, since the number of the connecting metal fittings 5 used for the construction of the cabinet 1 is the same as the number of the corner portions C, which is the minimum necessary number, the connecting metal fitting cost can be reduced. Further, the single-piece connecting metal fitting 5 obtained by bending a metal plate is easy to manufacture, can be mass-produced, and the unit price can be reduced, so that the cost of the connecting metal can be further reduced.
また、キャビネット１の構築に使用される８個全ての連結金具５は、いずれの枠材２の外面に露出せず、平行六面体のキャビネット１の各六面は枠材２のみで形成されているので、複数のキャビネット同士を密着させて横並べ、或いは、段積みする際に連結金具５が邪魔しない。キャビネット同士を段積みする際には、キャビネット１の上段の連結金具５の連結部５−３の上面が梁部材の第１枠材２−１と第２枠材２−２の上面と面一となって、段済みするキャビネットの支持面として利用できるので、より安定した段積みが行える。 Further, all the eight connecting metal fittings 5 used for the construction of the cabinet 1 are not exposed to the outer surface of any frame member 2, and each six surfaces of the parallelepiped cabinet 1 are formed of only the frame member 2. Therefore, the connecting metal fitting 5 does not interfere when a plurality of cabinets are brought into close contact with each other and stacked side by side or stacked. When stacking the cabinets, the upper surface of the connecting portion 5-3 of the upper connecting bracket 5 of the cabinet 1 is flush with the upper surfaces of the first frame member 2-1 and the second frame member 2-2 of the beam member. Thus, since it can be used as a support surface for a cabinet that has been stepped, more stable stacking can be performed.
さらに、連結金具５は、次のように３本の枠材２を安定した強度で連結する。 Further, the connection fitting 5 connects the three frame members 2 with stable strength as follows.
図６にキャビネット１の使用例を示すと、これはキャビネット１の最上段の４つの角部Ｃを構成する個々の連結金具５に吊りボルト２１を固定して、ワイヤ２３でキャビネット１を吊り上げるときのものである。連結金具５の連結部５−３の取付穴８に吊りボルト２１を挿通してナット２２で固定する。４つの角部Ｃの各吊りボルト２１にクレーン車などからのワイヤ２３を連結してキャビネット１を吊り上げる。このとき、連結金具５にほぼ真上に荷重が加わり、この荷重が第１取付板部５−１と第２取付板部５−２を介して複数本全てのボルト１０に加わる。第１取付板部５−１と第２取付板部５−２の各々が略鉛直な平板であるため、キャビネット吊り上げ時にボルト１０に加わる荷重方向は、複数本全てのボルト１０に対してボルト軸方向と直交するボルト剪断方向である。この剪断方向はボルト止め強度が最も大きく、かつ、安定する方向であるため、１つの連結金具５による３本の枠材２の連結強度が大きく、かつ、安定したものとなる。このような連結金具５がキャビネット１の計８箇所の角部Ｃで枠材２を連結するため、キャビネット１は吊り下げ時のみならず強度的に安定したものとなる。 An example of use of the cabinet 1 is shown in FIG. 6. This is when the hanging bolts 21 are fixed to the individual connection fittings 5 constituting the upper four corners C of the cabinet 1 and the cabinet 1 is lifted by the wires 23. belongs to. The suspension bolt 21 is inserted into the mounting hole 8 of the connecting portion 5-3 of the connecting metal 5 and fixed with the nut 22. The cabinet 1 is lifted by connecting a wire 23 from a crane truck or the like to the suspension bolts 21 at the four corners C. At this time, a load is applied almost directly to the connection fitting 5, and this load is applied to all the bolts 10 via the first mounting plate portion 5-1 and the second mounting plate portion 5-2. Since each of the first mounting plate portion 5-1 and the second mounting plate portion 5-2 is a substantially vertical flat plate, the load direction applied to the bolt 10 when the cabinet is lifted is the bolt shaft with respect to all the plurality of bolts 10. It is a bolt shear direction orthogonal to the direction. Since this shearing direction is the direction in which the bolting strength is the largest and is stable, the connection strength of the three frame members 2 by one connection fitting 5 is large and stable. Since such a connection fitting 5 connects the frame member 2 with a total of eight corners C of the cabinet 1, the cabinet 1 is stable not only when suspended but also in strength.
次に、図７〜図９に基づいて、図４の連結金具５の変形例を説明する。なお、形状や機能が同じ部分には同一参照符号を付して説明の重複を避ける。 Next, based on FIGS. 7-9, the modification of the coupling metal fitting 5 of FIG. 4 is demonstrated. In addition, the same reference number is attached | subjected to a part with the same shape and function, and duplication of description is avoided.
図７の斜視図と図８の展開図に示される連結金具５’の図４の連結金具５と相違するところは、第１取付板部５−１と第２取付板部５−２を小形化したことであり、連結部５−３の形状は同じである。第１取付板部５−１は、折曲基端部５ａ−１と中間部５ｂ−１と張出端部５ｃ−１を有する略Ｌ形平板で、中間部５ｂ−１が長さ方向で小形化される。第２取付板部５−２は、折曲基端部５ａ―２とこの折曲基端部５ａ−２から直接的に延在する張出端部５ｃ−２を有する略Ｉ形平板で、図４の連結金具５における中間部５ｂ−２を省略している。この省略で第２取付板部５−２の長さが短くなり、その分、第１取付板部５−１の長さも短くなる。連結部５−３の直交二辺から各取付板部５−１、５−２を直角に山折りすると、第２取付板部５−２の折曲基端部５ａ−２と張出端部５ｃ−２が同じ高さで横並びし、張出端部５ｃ−２と第１取付板部５−１の折曲基端部５ａ−１が直交して交差し、それぞれの張出端部５ｃ―１、５ｃ−２が相手側取付板部の外面から張り出す。 The connecting bracket 5 ′ shown in the perspective view of FIG. 7 and the developed view of FIG. 8 is different from the connecting bracket 5 of FIG. 4 in that the first mounting plate portion 5-1 and the second mounting plate portion 5-2 are small. That is, the shape of the connecting portion 5-3 is the same. The first mounting plate portion 5-1 is a substantially L-shaped flat plate having a bent base end portion 5a-1, an intermediate portion 5b-1, and a protruding end portion 5c-1, and the intermediate portion 5b-1 is in the length direction. Miniaturized. The second mounting plate portion 5-2 is a substantially I-shaped flat plate having a bent base end portion 5a-2 and a protruding end portion 5c-2 extending directly from the bent base end portion 5a-2. The intermediate part 5b-2 in the connecting metal fitting 5 of FIG. 4 is omitted. By this omission, the length of the second mounting plate portion 5-2 is shortened, and accordingly, the length of the first mounting plate portion 5-1 is also shortened. When the mounting plate portions 5-1 and 5-2 are mountain-folded at right angles from two orthogonal sides of the connecting portion 5-3, the bent base end portion 5a-2 and the overhang end portion of the second mounting plate portion 5-2 5c-2 are arranged side by side at the same height, the overhanging end portion 5c-2 and the bent base end portion 5a-1 of the first mounting plate portion 5-1 intersect at right angles, and each overhanging end portion 5c -1, 5c-2 protrudes from the outer surface of the counterpart mounting plate.
図７の連結金具５’で連結される３本の枠材２を図９に示すと、第１枠材２−１の一方の面Ｍ１の端部に第３枠材２−３の端面を接合し、第１枠材２−１の他の面Ｍ２の端部に接合した連結金具５’の張出端部５ｃ−２に第２枠材２−２の端面Ｎ３を接合する形態と成る。この３本の枠材２は、１つの連結金具５’で次のように連結される。 When the three frame members 2 connected by the connecting metal fitting 5 ′ of FIG. 7 are shown in FIG. 9, the end surface of the third frame member 2-3 is attached to the end of one surface M1 of the first frame member 2-1. The end face N3 of the second frame member 2-2 is joined to the overhanging end portion 5c-2 of the connecting metal fitting 5 'joined to the end portion of the other surface M2 of the first frame member 2-1. . The three frame members 2 are connected as follows by one connecting fitting 5 '.
連結金具５’の第２取付板部５−２の折曲基端部５ａ―２を第３枠材２−３の面Ｎ１の端部に接合してボルト止めし、張出端部５ｃ−２を第１枠材２−１の面Ｍ２の端部に接合してボルト止めして、第２取付板部５−２で第１枠材２−１と第３枠材２−３を直交させて連結すると共に、第１取付板部５−１の張出端部５ｃ−１を第１枠材２−１の面Ｍ１の端部に接合してボルト止めする。次に、第２枠材２−２の端面Ｎ３を第１枠材２−１端部の張出端部５ｃ−２に突き合せた状態で、第２枠材２−２の面Ｎ１の端部を連結金具５’の第１取付板部５−１の折曲基端部５ａ−１に接合してボルト止めする。この段階で、第１取付板部５−１が第１枠材２−１と第２枠材２−２を直交させて連結し、結果的に連結部５−３が第２枠材２−２と第３枠材２−３を直交させて連結する。 The bent base end portion 5a-2 of the second mounting plate portion 5-2 of the connecting metal fitting 5 'is joined to the end portion of the surface N1 of the third frame member 2-3 and bolted, and the overhang end portion 5c- 2 is joined to the end of the surface M2 of the first frame member 2-1 and bolted, and the first frame member 2-1 and the third frame member 2-3 are orthogonally crossed by the second mounting plate portion 5-2. The projecting end portion 5c-1 of the first mounting plate portion 5-1 is joined to the end portion of the surface M1 of the first frame member 2-1, and is bolted. Next, the end of the surface N1 of the second frame member 2-2 in a state where the end surface N3 of the second frame member 2-2 is abutted against the protruding end portion 5c-2 of the end portion of the first frame member 2-1. The portion is joined to the bent base end portion 5a-1 of the first mounting plate portion 5-1 of the connection fitting 5 'and bolted. At this stage, the first mounting plate portion 5-1 connects the first frame member 2-1 and the second frame member 2-2 at right angles, and as a result, the connection portion 5-3 becomes the second frame member 2-. 2 and the third frame member 2-3 are connected orthogonally.
図９で分かるように、連結金具５’の略Ｉ形平板の第２取付板部５−２の張出端部５ｃ−２が第１枠材２−１の端部と第２枠材２−２の端面Ｎ３の間に隠されるため、連結金具５’の露呈部分が少なくなり、キャビネットの外観がより良好となる。また、連結金具５’は、第１取付板部５−１と第２取付板部５−２が長さ方向で小形小面積化されるので、材料費が少なくでき、単価を低減させることができる。 As can be seen in FIG. 9, the protruding end portion 5 c-2 of the second mounting plate portion 5-2 of the substantially I-shaped flat plate of the connecting metal fitting 5 ′ is the end portion of the first frame member 2-1 and the second frame member 2. -2 is hidden between the end faces N3, the exposed portion of the connecting metal fitting 5 'is reduced, and the appearance of the cabinet is improved. In addition, since the first mounting plate portion 5-1 and the second mounting plate portion 5-2 are reduced in size and area in the length direction, the connecting metal fitting 5 'can reduce the material cost and reduce the unit price. it can.
以上の実施の形態のキャビネット１は、平行六面体枠の計８頂点の角部Ｃに連結金具５を使用したもので、一部の角部を除く選択された角部にのみ連結金具５を使用することもできる。この場合、連結金具５を使用しない角部に別の直角専用コーナー金具を使用することができる。このコーナー金具の具体例を図１０〜図１２を参照して説明する。 The cabinet 1 of the above embodiment uses the connecting metal fittings 5 at the corners C of the total apexes of the parallelepiped frame, and uses the connecting metal fittings 5 only at selected corners excluding some corners. You can also In this case, another right-angled corner metal fitting can be used at a corner where the coupling metal fitting 5 is not used. A specific example of the corner fitting will be described with reference to FIGS.
図１０の斜視図と図１１の展開図に示すコーナー金具９は、図１２に示す１本の枠材２（柱部材である第１枠材）の途中箇所に別の１本の枠材（梁部材で、以下、第４枠材と称する）２−４を直交させて連結する用途に適する。コーナー金具９は、直交する２本の枠材２、２−４の互いに直交して対向するそれぞれの内側取付面に接合してボルトなどで固定される内側取付板部９−１と、２本の枠材２、２−４の側面にあって同一平面で互いに直交するそれぞれの取付面に接合してボルトなどで固定される側面取付板部９−２と、内側取付板部９−１と側面取付板部９−２を連結する連結部９−３を有する。内側取付板部９−１は両端部９ａ−１、９ｂ−１を外面側に約４５度で屈曲させた横長の屈曲平板で、それぞれの端部９ａ−１、９ｂ−１にサイコロの四の目状に取付穴６ｄが形成される。側面取付板部９−２は略直角二等辺三角形の平板で、直交二辺に沿って一列状に複数の取付穴６ｅが形成される。連結部９−３を略直角に折曲して、内側取付板部９−１と側面取付板部９−２が直交する一枚板物のコーナー金具９が製造される。このようなコーナー金具９は、上記連結金具５と同様に安価に量産でき、保守管理が容易である。 The corner metal fitting 9 shown in the perspective view of FIG. 10 and the developed view of FIG. 11 has another frame material (one frame material (first frame material which is a pillar member) shown in FIG. This is a beam member and is hereinafter referred to as a fourth frame member). The corner metal fitting 9 includes two inner mounting plate portions 9-1 that are joined to respective inner mounting surfaces of the two orthogonal frame members 2 and 2-4 that are orthogonal to each other and fixed by bolts or the like. Side mounting plate portions 9-2 that are joined to respective mounting surfaces that are orthogonal to each other in the same plane and are fixed with bolts, etc., and inner mounting plate portions 9-1 It has the connection part 9-3 which connects the side surface attachment board part 9-2. The inner mounting plate portion 9-1 is a horizontally long bent flat plate in which both end portions 9a-1 and 9b-1 are bent at an outer surface side of about 45 degrees, and each end portion 9a-1 and 9b-1 has four dice. Mounting holes 6d are formed in a grid. The side surface mounting plate portion 9-2 is a flat plate with a substantially right isosceles triangle, and a plurality of mounting holes 6e are formed in a line along two orthogonal sides. The connecting portion 9-3 is bent at a substantially right angle to produce a single piece corner fitting 9 in which the inner mounting plate portion 9-1 and the side surface mounting plate portion 9-2 are orthogonal to each other. Such corner fittings 9 can be mass-produced at low cost as in the case of the connecting fittings 5 and are easy to maintain and manage.
図１２に示すように、コーナー金具９は枠材２と第４枠材２−４のコーナー部分に嵌着されて、内側取付板部９−１の両端部が枠材２と第４枠材２−４の内面に接合されてボルト１０で固定され、側面取付板部９−２の直交二辺の辺部分が枠材２と第４枠材２−４の側面に接合されてボルト１０で固定される。コーナー金具９を直交する枠材２と第４枠材２−４の内面と側面の両方に固定することで、２本の枠材２、２−４が強固に連結される。図１２のように１本の枠材２の端部と途中部分に連結金具５とコーナー金具９を連結することで、枠材同士の連結強度が増す。また、コーナー金具９で連結された第４枠材２−４がキャビネット全体を補強して、角部Ｃの連結金具５による枠材連結強度を常に高く安定させる。また、コーナー金具９は枠材２の任意の途中箇所に連結することができるので、キャビネットの枠組構造の変更を容易なものにする。 As shown in FIG. 12, the corner metal fitting 9 is fitted to the corner portions of the frame member 2 and the fourth frame member 2-4, and both end portions of the inner mounting plate portion 9-1 are the frame member 2 and the fourth frame member. It is joined to the inner surface of 2-4 and fixed with the bolt 10, and the side portions of two orthogonal sides of the side surface mounting plate portion 9-2 are joined to the side surfaces of the frame member 2 and the fourth frame member 2-4. Fixed. By fixing the corner metal fitting 9 to both the inner surface and the side surface of the orthogonal frame material 2 and the fourth frame material 2-4, the two frame materials 2, 2-4 are firmly connected. As shown in FIG. 12, the connection strength between the frame members is increased by connecting the connection fitting 5 and the corner fitting 9 to the end portion and the middle portion of one frame member 2. Moreover, the 4th frame material 2-4 connected with the corner metal fitting 9 reinforces the whole cabinet, and always stabilizes the frame material connection intensity | strength by the connection metal fitting 5 of the corner | angular part C high. Moreover, since the corner metal fitting 9 can be connected to an arbitrary midpoint of the frame member 2, it is easy to change the frame structure of the cabinet.
