Description

本発明は垂直方向に配設されるバスダクトを支持する支持構造に関するものである。   The present invention relates to a support structure for supporting a bus duct arranged in a vertical direction.

一般にバスダクトは、長尺な導体板をハウジングの内部に収納保持する構成となっている。このバスダクトは、工場施設やビルの主電力供給ラインなどに広く用いられている。   Generally, a bus duct is configured to store and hold a long conductor plate inside a housing. This bus duct is widely used in factory facilities and main power supply lines of buildings.

高層ビルに配設されるバスダクトは、床面を貫通させて垂直方向に配設したり、水平方向に配設される。垂直方向に配設する場合、バスダクトを構造物に支持する必要があり、その支持構造として図１０及び図１１に示すようなものがある。   The bus duct disposed in the high-rise building is disposed in the vertical direction through the floor surface or in the horizontal direction. When arranged in the vertical direction, it is necessary to support the bus duct on the structure, and there are the support structures as shown in FIGS. 10 and 11.

図１０及び図１１の垂直支持構造は、まず、バスダクトAは、並列する３本の平型導体BをハウジングC内に収納した構成となっており、ハウジングCの導体幅方向両端側には、構造物へ固定するための取付部Dが形成され、取付部Dにボルト取付用孔が２箇所ずつ設けられている。   In the vertical support structure shown in FIGS. 10 and 11, first, the bus duct A has a configuration in which three flat conductors B arranged in parallel are housed in the housing C. A mounting portion D for fixing to the structure is formed, and the mounting portion D is provided with two bolt mounting holes.

そして、二つの断面Ｌ字の取付部材EでバスダクトAを挟持するように、ハウジングCは、一方の取付部材Eに一方の取付部Dが固定され、他方の取付部材Eに他方の取付部Dが固定されている。これら取付部材Eは、断面が［型でレール状の固定部材Fを介して構造物の床面に固定されている。固定部材Fは床面に固定されている。   The housing C has one attachment member D fixed to one attachment member E and the other attachment member E attached to the other attachment portion D so that the bus duct A is sandwiched between two attachment members E having an L-shaped cross section. Is fixed. These attachment members E are fixed to the floor surface of the structure via a fixed rail F in the form of a rail. The fixing member F is fixed to the floor surface.

この垂直支持構造では、バスダクトAの重量を支持しながら、動かないように支持する必要があることから、上記支持構造では、ハウジングCと取付部材EとをボルトGにより固定している。   In this vertical support structure, since it is necessary to support the weight of the bus duct A so as not to move, the housing C and the mounting member E are fixed by bolts G in the support structure.

即ち、取付部材EのＬ字の一方の面Hには、ハウジングCを固定するための第１ボルト孔が２箇所形成され、他方の面Jには、固定部材Fに固定するための第２ボルト孔が２箇所形成されている。ハウジングCには、取付部材Eの第１ボルト孔に対向させて、ボルト孔が形成されている。   That is, two first bolt holes for fixing the housing C are formed on one side H of the L-shape of the mounting member E, and a second side for fixing the fixing member F on the other side J. Two bolt holes are formed. Bolt holes are formed in the housing C so as to face the first bolt holes of the mounting member E.

取付部材Eの第１ボルト孔とハウジングCのボルト孔を位置合わせして、これらボルト孔にボルトGを貫通させてナットKにより締め付け固定することにより、一対の取付部材EにハウジングCが固定される。   The first bolt hole of the mounting member E and the bolt hole of the housing C are aligned, the bolt G is passed through these bolt holes, and the nut K is fastened and fixed, whereby the housing C is fixed to the pair of mounting members E. The

そして、取付部材Eの第２ボルト孔を固定部材Fのボルト孔に位置合わせして、ボルト孔にボルトLを貫通させてナットにより締め付け固定することにより、ハウジングCが取付部材Eを介して固定部材Fに固定される。   Then, the second bolt hole of the mounting member E is aligned with the bolt hole of the fixing member F, the bolt L is passed through the bolt hole, and is tightened and fixed with a nut, so that the housing C is fixed via the mounting member E. Fixed to member F.

上記の支持構造では、バスダクトAにおけるハウジングCの取付部Dと、取付部材Eには、ボルト孔を貫通形成しているので、孔開け作業という煩雑な作業を要する。さらに、それぞれのボルト孔を位置合わせしてボルト締めをしなければならず、孔の位置合わせを行うのも煩雑な作業となる。   In the above support structure, since the bolt hole is formed through the mounting portion D of the housing C and the mounting member E in the bus duct A, a complicated operation of drilling is required. Furthermore, each bolt hole must be aligned and bolted, and the alignment of the holes is a cumbersome operation.

そこで、本出願人は、特許文献１に示すような、バスダクトと取付部材とをボルトにより固定しない支持構造を提案した。この支持構造は、バスダクトのハウジングに設ける取付片を断面Ｌ型に形成し、このＬ型の突出部分における長手方向の一部をＷ型状に形成しておく。そして、このＷ型状の部分のみを取付片の根元部分と同じ平面上になるように折り曲げる。   Therefore, the present applicant has proposed a support structure in which the bus duct and the mounting member are not fixed with bolts as shown in Patent Document 1. In this support structure, the mounting piece provided on the housing of the bus duct is formed in an L-shaped cross section, and a part of the L-shaped protruding portion in the longitudinal direction is formed in a W shape. Then, only this W-shaped portion is bent so as to be on the same plane as the root portion of the mounting piece.

次に、Ｗ型状の突出部分を断面［型の２つの保持金具に形成したスリット部で保持し、Ｗ型状の凹部分に連結金具を配置させて、これら保持金具と連結金具とをボルトにより固定して、保持金具と連結金具とがハウジングのＷ型状部分に取り付けられる。   Next, the W-shaped projecting portion is held in a cross-section [slit portion formed in the two holding brackets of the mold, the connecting brackets are arranged in the W-shaped concave portions, and the holding brackets and the connecting brackets are bolted. The holding metal fitting and the connecting metal fitting are attached to the W-shaped portion of the housing.

この保持金具と連結金具とが結合されたものが取付部材となり、バスダクトがボルトにより固定されることなく、保持金具と連結金具に支持された状態にすることができる。バスダクトは、保持金具と連結金具を介して固定部材にボルトにより固定される。   A combination of the holding metal fitting and the connection metal fitting serves as an attachment member, and the bus duct can be supported by the holding metal fitting and the connection metal fitting without being fixed by bolts. The bus duct is fixed to the fixing member by bolts via the holding metal fitting and the connecting metal fitting.

特開平８−１９１４７号公報（図10）JP-A-8-19147 (FIG. 10)

しかし、保持金具と連結金具を用いてバスダクトを支持する構成とする場合、バスダクトのハウジングにＷ型状の突起部分をわざわざ形成しなくてはならず、しかも、突起部分の形成位置も特定しなければならないので、ハウジングの形成作業が煩雑となる。   However, when the bus duct is configured to be supported using the holding metal fitting and the connecting metal fitting, a W-shaped protrusion must be formed on the bus duct housing, and the position where the protrusion is formed must be specified. Therefore, the work of forming the housing becomes complicated.

また、２つの保持金具のスリットをハウジングの突起部分に合わせておいて、連結金具を凹部分に合わせる作業も要するので、組み付け作業も煩雑となる。   In addition, the work of assembling is complicated because it is necessary to align the slits of the two holding metal fittings with the protruding portions of the housing and to match the connecting metal fittings to the concave portions.

従って、本発明の目的は、バスダクトに特別な加工を施すことなく、かつ、バスダクトをボルト止めすることなく、バスダクトを確実に構造物に固定ができる支持構造を提供することにある。   Therefore, an object of the present invention is to provide a support structure that can securely fix a bus duct to a structure without applying special processing to the bus duct and without bolting the bus duct.

本発明は、垂直方向に布設されるバスダクトを支持するバスダクトの支持構造であって、バスダクトが挟持される一対の取付部材と、ハウジングが当接されるとともにバスダクトの位置合わせを行うガイド部と、取付部材を連結する連結部材と、構造物に固定され、取付部材が固定される固定部材とを具える。   The present invention is a bus duct support structure for supporting a bus duct laid in a vertical direction, a pair of mounting members that sandwich the bus duct, a guide portion that contacts the housing and aligns the bus duct, A connecting member that connects the mounting members and a fixing member that is fixed to the structure and to which the mounting members are fixed.

取付部材は、バスダクトにおける長尺板状の導体を収納するハウジングを挟み込む一対で構成される。   The mounting member is configured as a pair that sandwiches a housing that houses a long plate-like conductor in the bus duct.

ガイド部は、取付部材の対向面のそれぞれに固定される。ガイド部は、取付部材とハウジングの間に介在され、このガイド部によりバスダクトの取付部材に対する位置合わせが行われる。ガイド部におけるハウジング支持面は、摩擦抵抗を大きくしている。摩擦抵抗が大きい支持面とは、例えば、支持面にローレット加工を施すことによって得られる。   The guide portion is fixed to each of the opposing surfaces of the mounting member. The guide portion is interposed between the attachment member and the housing, and the guide portion aligns the bus duct with the attachment member. The housing support surface in the guide portion increases the frictional resistance. A support surface having a large frictional resistance can be obtained, for example, by knurling the support surface.

連結部材は、取付部材の間にハウジングを配置させた状態で、取付部材をハウジング挟持方向に押圧しながら連結する構成となっている。例えば、ボルトとナットが挙げられ、取付部材にボルト孔を２つ以上形成し、対向する取付部材のボルト孔にボルトを貫通させてナットにより締め付けて固定することにより、一対の取付部材が連結される。   The connecting member is configured to connect the attaching member while pressing the attaching member in the housing clamping direction in a state where the housing is disposed between the attaching members. For example, a bolt and a nut may be mentioned. A pair of mounting members are connected by forming two or more bolt holes in the mounting member, passing the bolts through the bolt holes of the mounting members facing each other, and tightening and fixing with the nuts. The

固定部材は、構造物の床面に予め固定しておき、取付部材をボルトなどによりこの固定部材に固定する構成となっている。このとき、取付部材が固定部材に対してバスダクトの長手方向に動かないように固定するようにしてもよいし、ボルトにスプリングを介在させておいて、取付部材が固定部材に対してバスダクトの長手方向に移動できるようにしてもよい。   The fixing member is fixed in advance to the floor of the structure, and the mounting member is fixed to the fixing member with a bolt or the like. At this time, the mounting member may be fixed to the fixing member so as not to move in the longitudinal direction of the bus duct, or a spring is interposed in the bolt, and the mounting member is fixed to the fixing member in the longitudinal direction of the bus duct. It may be possible to move in the direction.

さらに、ガイド部は、ハウジングの側板における導体幅方向両側縁部にハウジング支持面を当接させるようにすることが好ましい。その構成としては、ガイド部におけるハウジングの側面との対向面で、ハウジングの導体幅方向両側縁部に対向する位置に突起部を設け、この突起部をハウジング支持面とすることができる。このとき、突起部にローレット加工などを施してハウジング支持面の摩擦抵抗を大きくする。   Furthermore, it is preferable that a guide part makes a housing support surface contact | abut to the conductor width direction both side edge part in the side plate of a housing. As a configuration thereof, a protruding portion can be provided at a position facing the side surface of the housing in the conductor width direction on the surface of the guide portion facing the side surface of the housing, and this protruding portion can be used as a housing support surface. At this time, knurling or the like is applied to the protrusion to increase the frictional resistance of the housing support surface.

また、他の構成として、バスダクトのハウジングに、ハウジングの側板における導体幅方向両側縁部に長手方向に延びる係合突出面を形成しておいて、この係合突出面のみをガイド部に当接させて支持する構成としてもよい。この場合も、係合突出面と当接するガイド部のハウジング支持面は、ローレット加工などを施して摩擦抵抗を大きくする。   As another configuration, an engagement protrusion surface extending in the longitudinal direction is formed on both side edges of the conductor width direction of the side plate of the housing on the housing of the bus duct, and only the engagement protrusion surface is brought into contact with the guide portion. It is good also as a structure supported. Also in this case, the housing support surface of the guide portion that comes into contact with the engagement protrusion surface is subjected to knurling or the like to increase the frictional resistance.

本発明のバスダクトの支持構造によれば、取付部材でバスダクトのハウジングを挟んでおいて、連結部材を用いて取付部材でハウジングを押圧状態で挟持できる。また、ガイド部によりハウジングの連結部材に対する位置も容易に合わせられるし、摩擦抵抗の大きいハウジング支持面でハウジングを支持しているので、取付部材に対してハウジングがずれることなく所定の位置に支持しておくことができる。   According to the bus duct support structure of the present invention, the housing of the bus duct can be sandwiched by the mounting member, and the housing can be clamped by the mounting member using the connecting member. Further, the position of the housing relative to the connecting member can be easily adjusted by the guide portion, and the housing is supported by the housing support surface having a large frictional resistance, so that the housing is supported at a predetermined position without being displaced with respect to the mounting member. I can keep it.

さらに、ガイド部のハウジング支持面を、ハウジングの側板における導体幅方向両側縁部に当接させるようにすれば、連結部材は、通常、バスダクトの外方に配置されるので、連結部材の配置近くで取付部材をハウジングに押圧させることができる。その結果、連結部材による締付力の最も作用する位置で取付部材はハウジングを支持することができる。   Furthermore, if the housing support surface of the guide part is brought into contact with both side edges in the conductor width direction of the side plate of the housing, the connecting member is usually arranged outside the bus duct, so that it is close to the arrangement of the connecting member. Thus, the mounting member can be pressed against the housing. As a result, the mounting member can support the housing at a position where the tightening force by the connecting member is most effective.

以下、本発明の実施の形態を説明する。本実施形態は、図１に示すように、長尺板状の導体11をハウジング12に収納したバスダクト1を垂直方向に配設した際のバスダクト支持構造である。   Embodiments of the present invention will be described below. As shown in FIG. 1, the present embodiment is a bus duct support structure when a bus duct 1 in which a long plate-like conductor 11 is housed in a housing 12 is arranged in the vertical direction.

バスダクト1は、図８に示すように、ハウジング12内に導体11を収納した構成である。バスダクト1は、図示していないが端部に接続部が取り付けられ、別のユニットと連結されることにより線路を構成することができる。   As shown in FIG. 8, the bus duct 1 has a configuration in which a conductor 11 is accommodated in a housing 12. Although not shown, the bus duct 1 has a connection portion attached to an end thereof and can be connected to another unit to constitute a line.

ハウジング12は、同一形状の一対の分割片12a,12bを組み合わせて構成されており、分割片12a,12bのそれぞれは、断面が矩形で樋型をした導体収納部13と、この導体収納部13の両開口側縁から互いに離れる方向に伸びる接合部14と、接合部の端部においてこの接合部にほぼ直交する補強部15とを有する。両分割片の導体収納部13の間に形成される空間に導体11を収納するようになっている。   The housing 12 is configured by combining a pair of divided pieces 12a and 12b having the same shape. Each of the divided pieces 12a and 12b includes a conductor housing portion 13 having a rectangular cross section and a bowl shape, and the conductor housing portion 13 The joint 14 extends in the direction away from the both edges of the opening, and the reinforcement 15 is substantially orthogonal to the joint at the end of the joint. The conductor 11 is accommodated in a space formed between the conductor accommodating portions 13 of both divided pieces.

さらに、導体収納部13の外側面には、断面がL型の突出部16がバスダクトの長手方向に連続形成されている。この突出部16は、アルミニウムの押し出しによりハウジングと一体に形成され、ハウジングの長手方向全長にわたって形成されている。   Furthermore, an L-shaped projecting portion 16 is continuously formed on the outer surface of the conductor housing portion 13 in the longitudinal direction of the bus duct. The protrusion 16 is formed integrally with the housing by extrusion of aluminum, and is formed over the entire length in the longitudinal direction of the housing.

本実施形態では、一つの分割片における導体収納部13の外側平面部における両側縁部に一対の突出部16を対向して設けている。これら突出部16における導体収納部13の平面部と平行する面を後述するガイド部3に係合する係合突出面17としている。突出部16は、ガイド部3に係合突出面17を圧接させたときに、十分な強度が得られるように材質、形状、サイズが設定される。一方、導体11は、絶縁被覆を有する導体板から構成され、３枚の導体板を並列してハウジング12内に収納している。   In the present embodiment, a pair of projecting portions 16 are provided to face both side edge portions in the outer plane portion of the conductor housing portion 13 in one divided piece. A surface of the projecting portion 16 parallel to the flat surface of the conductor housing portion 13 is an engaging projecting surface 17 that engages with a guide portion 3 described later. The protrusion 16 is set in material, shape, and size so that sufficient strength can be obtained when the engaging protrusion 17 is pressed against the guide 3. On the other hand, the conductor 11 is composed of a conductor plate having an insulating coating, and three conductor plates are accommodated in the housing 12 in parallel.

次に、バスダクトの支持構造について図面に基づいて説明する。本実施形態にかかるバスダクトの支持構造は、図１乃至図３に示すように、垂直方向に布設されたバスダクト1を支持するものであって、バスダクト1のハウジング12に取り付けられる取付部材2と、構造物に対して固定され、取付部材2を介してハウジング12が固定される固定部材4とを備えている。   Next, the bus duct support structure will be described with reference to the drawings. As shown in FIGS. 1 to 3, the bus duct support structure according to the present embodiment supports a bus duct 1 installed in a vertical direction, and includes an attachment member 2 attached to a housing 12 of the bus duct 1, And a fixing member 4 that is fixed to the structure and to which the housing 12 is fixed via the attachment member 2.

取付部材2は、バスダクト1のハウジング12を挟み込む一対で構成され、ハウジング12を形成する一方の分割片12aの突出部16の係合突出面17が対向する第一取付部材2aと、他方の分割片12bの突出部16の係合突出面17が対向する第二取付部材2bとからなる。   The mounting member 2 is composed of a pair sandwiching the housing 12 of the bus duct 1, the first mounting member 2a facing the engagement projecting surface 17 of the projecting portion 16 of one split piece 12a forming the housing 12, and the other split It consists of the 2nd attachment member 2b which the engagement protrusion surface 17 of the protrusion part 16 of the piece 12b opposes.

第一取付部材2aと第二取付部材2bとは、平行した第一支持面21と第二支持面22、そしてこれら支持面21,22の一端部において連結する連結面23とを有する長尺で断面［型をしている。第一取付部材2aと第二取付部材2bは、第一支持面21と第二支持面22の長手方向一端側に固定用ボルト孔が一つずつ形成され、連結面23には、長手方向両端側に二つの連結用ボルト孔が形成されている。   The first mounting member 2a and the second mounting member 2b are long having a parallel first support surface 21, a second support surface 22, and a connecting surface 23 connected at one end of the support surfaces 21, 22. Cross section [shaped. The first mounting member 2a and the second mounting member 2b are each formed with one fixing bolt hole at one end in the longitudinal direction of the first support surface 21 and the second support surface 22, and the connecting surface 23 has both longitudinal ends. Two connecting bolt holes are formed on the side.

各取付部材2a,2bにおける連結面23の外面、即ち、二つの取付部材2a,2bを対向配置させた時の対向面には、バスダクトの位置合わせを行うガイド部3が設けられている。このガイド部3は、図４から図７に示すように、取付部材2の連結面23の幅と同一幅を有する板状部材からなり、板状部材の長手方向両端部を屈曲させて断面［型にして、両端側の屈曲部32とこれら屈曲部32の間の支持部31とから構成される。二つの屈曲部32の間に、バスダクト1のハウジング12における導体収納部13が入り込むようになっており、これら屈曲部32がハウジング12の位置を決めるガイドとなる。   On the outer surface of the connecting surface 23 of each mounting member 2a, 2b, that is, on the opposing surface when the two mounting members 2a, 2b are arranged to face each other, a guide portion 3 for aligning the bus duct is provided. As shown in FIGS. 4 to 7, the guide portion 3 is composed of a plate-like member having the same width as that of the connecting surface 23 of the mounting member 2, and is bent at both longitudinal ends of the plate-like member. The mold includes a bent portion 32 on both ends and a support portion 31 between the bent portions 32. Between the two bent portions 32, the conductor housing portion 13 in the housing 12 of the bus duct 1 is inserted, and these bent portions 32 serve as guides for determining the position of the housing 12.

ガイド部3は、図４に示すように、支持部31における屈曲部32の屈曲方向とは反対側の面を取付部材2の連結面23に当接させてボルトなどにより固定し、図７に示すように、支持部31の屈曲側の面における屈曲部32の近くに屈曲部32と平行して延びるハウジング支持面33が形成されている。   As shown in FIG. 4, the guide portion 3 has a surface opposite to the bending direction of the bent portion 32 of the support portion 31 in contact with the connecting surface 23 of the mounting member 2 and is fixed by a bolt or the like. As shown, a housing support surface 33 extending in parallel with the bent portion 32 is formed near the bent portion 32 on the bent side surface of the support portion 31.

このハウジング支持面33は、ローレット加工により摩擦抵抗が大きくなるようにしている。本実施形態では、ローレット加工により、ハウジング支持面33の表面を、平目、四角目、菱形目など、所望の摩擦抵抗となるように切削することができる。このハウジング支持面33には、ハウジング12の係合突出面17が当接するようになっており、係合突出面17をハウジング支持面33に当接させることにより、ハウジング12が取付部材2に対して動かないようにすることができる。   The housing support surface 33 is configured to increase the frictional resistance by knurling. In the present embodiment, the surface of the housing support surface 33 can be cut by knurling so as to have a desired frictional resistance, such as a flat mesh, a square mesh, and a diamond mesh. The housing support surface 33 is in contact with the engagement projecting surface 17 of the housing 12, and the housing 12 is brought into contact with the mounting member 2 by bringing the engagement projecting surface 17 into contact with the housing support surface 33. Can be prevented from moving.

なお、本実施形態では、バスダクト1のハウジング12の外面に突出部16を設けて、この突出部16の係合突出面17をガイド部3のハウジング支持面33で支持するようにしたが、ハウジング12に突出部を設けず、ガイド部3の支持部31における前記ローレット加工を施した部分を突出させて、この突出部分でハウジング12を支持するようにしてもよい。この場合は、この突出部分の表面にローレット加工を施す。   In this embodiment, the protruding portion 16 is provided on the outer surface of the housing 12 of the bus duct 1, and the engaging protruding surface 17 of the protruding portion 16 is supported by the housing support surface 33 of the guide portion 3. Instead of providing a protruding portion on 12, the knurled portion of the support portion 31 of the guide portion 3 may be protruded and the housing 12 may be supported by this protruding portion. In this case, knurling is performed on the surface of the protruding portion.

次に、図１に示すように、ハウジング12をガイド部3の屈曲部32の間に位置させて、二つの取付部材2a,2bによりハウジング12を挟み込む。そして、取付部材2a,2bの連結面23に設ける連結用ボルト孔に連結用ボルト61を挿通させて連結用ナット62を嵌めて締め付けることにより、取付部材2a,2bでハウジング12を押圧し、ハウジング12を取付部材2a,2bで挟持する。本実施形態では、連結用ボルト61と連結用ナット62により連結部材6が構成される。   Next, as shown in FIG. 1, the housing 12 is positioned between the bent portions 32 of the guide portion 3, and the housing 12 is sandwiched between the two attachment members 2a and 2b. Then, by inserting the connecting bolt 61 into the connecting bolt hole provided in the connecting surface 23 of the attaching members 2a and 2b and fitting the connecting nut 62 and tightening, the housing 12 is pressed by the attaching members 2a and 2b. 12 is sandwiched between the mounting members 2a and 2b. In the present embodiment, the connecting member 6 is constituted by the connecting bolt 61 and the connecting nut 62.

このように、取付部材2a,2bの間にハウジング12を配置させて連結部材6でハウジング12を挟持するように取付部材2a,2bを連結させたものを、構造物である床面7に、固定部材4を介して固定する。   In this way, the housing 12 is disposed between the mounting members 2a and 2b, and the mounting members 2a and 2b are connected so as to sandwich the housing 12 with the connecting member 6, the floor surface 7 being a structure, It is fixed via the fixing member 4.

固定部材4は、図２および図３に示すように、床面7を貫通するバスダクト1の貫通孔近傍に配設され、床面7にボルト止めされる２つの断面［型の第一部材41と、これら第一部材41の上面に直交して配置され、両端部において第一部材41にボルト止めされる断面［型状の第二部材42とから成る。第一部材41は、バスダクト1を挟んだ状態で平行に配置され、第二部材42もバスダクト1を挟んだ状態で平行に配置される。   2 and 3, the fixing member 4 is disposed in the vicinity of the through hole of the bus duct 1 that penetrates the floor surface 7, and has two cross-sections [first member 41 of a mold] that is bolted to the floor surface 7. And a cross-section [consisting of a mold-shaped second member 42, which is arranged perpendicular to the upper surface of the first member 41 and is bolted to the first member 41 at both ends. The first member 41 is arranged in parallel with the bus duct 1 in between, and the second member 42 is also arranged in parallel with the bus duct 1 in between.

第二部材42における上面には、ボルト孔が形成されており、このボルト孔に固定用ボルト51が挿通される。ボルト孔に挿通された固定用ボルト51は、第二部材42の上面に固定されるため、第二部材42の上面を挟むようにして第一ナット52が螺合され、さらに、この第一ナット52の上方に所定間隔を置いて第二ナット53が螺合されている。   Bolt holes are formed on the upper surface of the second member 42, and fixing bolts 51 are inserted into the bolt holes.

The elongation can be absorbed by the coil spring 55.

本実施形態では、ガイド部3で取付部材2a,2bへの位置決めを行いながら、摩擦抵抗の大きいハウジング支持面33でハウジング12を支持して、取付部材2でハウジング12を挟持する支持構造となっている。   In the present embodiment, while the guide portion 3 is positioned on the mounting members 2a and 2b, the housing 12 is supported by the housing support surface 33 having a high frictional resistance, and the housing 12 is sandwiched by the mounting member 2. ing.

ここで、ガイド部のハウジング支持面にローレット加工を施した場合と、ローレット加工を施さずハウジング支持面の摩擦抵抗を小さくした場合について、連結部材のボルト締付トルクを2452N・cm(250kgf・cm)としてハウジングを取付部材で支持したときのハウジングのずれを調べてみた。   Here, the bolt tightening torque of the connecting member is 2452 N · cm (250 kgf · cm) when the housing support surface of the guide portion is knurled and when the friction resistance of the housing support surface is reduced without knurling. ), The displacement of the housing when the housing was supported by the mounting member was examined.

ローレット加工を施していないハウジング支持面の場合には、ハウジングは、330kNで取付部材に対してずれが生じた。これに対し、ローレット加工を施したハウジング支持面の場合には、ハウジングは、10530kNで取付部材に対してずれが生じ、ローレット加工を施していない場合に比べて約３倍の保持力が得られた。   In the case of the housing support surface not subjected to knurling, the housing was displaced from the mounting member at 330 kN. On the other hand, in the case of a housing support surface that has been knurled, the housing is displaced with respect to the mounting member at 10530 kN, and a holding force that is approximately three times that of the case that has not been knurled is obtained. It was.

以上のように、本発明によれば、ハウジング12と取付部材2a,2bをボルトで固定することなく、取付部材2a,2bにハウジング12を所定の位置に固定でき、しかも、ハウジング12の取付部材への取付作業も容易に行える。   As described above, according to the present invention, the housing 12 can be fixed at a predetermined position to the mounting members 2a and 2b without fixing the housing 12 and the mounting members 2a and 2b with bolts. Can be easily attached to the camera.
