ａ）技術分野の説明
本発明は補強枠を使用して耐震性を向上させた閉鎖配電
盤に関する。DETAILED DESCRIPTION OF THE INVENTION a) Description of the Technical Field The present invention relates to a closed switchboard with improved earthquake resistance using a reinforcing frame.
ｂ）従来技術の説明
従来、閉鎖配電盤の耐震性を向上する方法として、閉鎖
配電盤を複数面列盤状態で設置する場合、閉鎖配電盤間
に、強固な枠をはさみ込んで剛性を上げたり、盤の頂部
を建物の壁から腕を出して、支持をすることが多い。b) Explanation of the prior art Conventionally, as a method to improve the seismic resistance of closed switchboards, when multiple closed switchboards are installed in a row, a strong frame is inserted between the closed switchboards to increase rigidity. The top of the building is often supported by extending an arm out from the wall of the building.
しかし、たとえば、盤間に枠をはさむ場合、枠の厚さを
あまり厚くすることができないため、枠自体の剛性を上
げることが困難で、一面ごとに設けなければならないな
どの欠点があった。However, for example, when inserting a frame between boards, the thickness of the frame cannot be made very thick, so it is difficult to increase the rigidity of the frame itself, and there are drawbacks such as having to install it on each side.
また、建物の壁から支持用の腕を出す場合には、地震時
に建物の振動と盤の頂部との振動に位相差が生ずること
もあり、その場合、盤の頂部に予想外の応力が発生する
おそれがあった。Additionally, when supporting arms are extended from the building wall, there may be a phase difference between the vibration of the building and the vibration of the top of the board during an earthquake, in which case unexpected stress will be generated at the top of the board. There was a risk that
また、補強枠を用いる場合、保守点検のスペースが少な
くなり作業性が低下する。Furthermore, when a reinforcing frame is used, there is less space for maintenance and inspection, which reduces work efficiency.
Ｃ）発明の目的
本発明の目的は、断面係数の大きな補強枠をフレームに
固着させ、かつこの補強枠に扉を設置することにより、
作業性が低下することなく、より剛性を大きくした閉鎖
配電盤を提供することにある。C) Purpose of the Invention The purpose of the present invention is to fix a reinforcing frame with a large section modulus to the frame and install a door on this reinforcing frame.
To provide a closed switchboard with greater rigidity without reducing workability.
ｄ）発明の構成 本発明の構成を図示する一実施例で説明する。d) Structure of the invention The configuration of the present invention will be explained with reference to an illustrated embodiment.
閉鎖配電盤の本体フレームｌａ、１ｂはそれぞれ箱状を
成し、かつ相互に正規の状態で列盤されている。The main body frames la and 1b of the closed switchboard each have a box shape, and are arranged side by side in a regular manner.
一方、枠２は平断面がコ字状になる如くチャンネルなど
で強固に組み立てたものである。On the other hand, the frame 2 is firmly assembled with channels or the like so that its planar cross section is U-shaped.
この枠２のコ字状を成す凹部には、前記フレームＩａ、
１ｂが背面から嵌合できるように、その幅寸法を決める
。In the U-shaped recess of this frame 2, the frame Ia,
The width dimension is determined so that 1b can be fitted from the back side.
また枠２側にはフレーム１ａ。１ｂの側面に設けた列盤
用の連結孔３と一致する位置に連結孔４を設ける。Also, on the frame 2 side is frame 1a. A connecting hole 4 is provided at a position that coincides with the connecting hole 3 for parallel boards provided on the side surface of 1b.
前記本体フレームｌａ、Ｉｂ自体には背面扉を設けず、
かわりに、枠２の背面側に扉５を開閉可能に取り付ける
。The main body frames la, Ib themselves are not provided with a rear door,
Instead, a door 5 is attached to the back side of the frame 2 so that it can be opened and closed.
また枠２の底部になる水平部材には図示していないが基
礎に固定するだめの孔を設け、この孔に挿通するボルト
６で基礎に強固に固定される。Further, although not shown, a hole for fixing to the foundation is provided in the horizontal member serving as the bottom of the frame 2, and the frame 2 is firmly fixed to the foundation by a bolt 6 inserted through this hole.
このように枠２により一体的に結合された閉鎖配電盤の
本体フレーム１ａ、ｌｂを更に複数列盤する場合には、
枠２の側面を貫通する母線６を用いて、各本体フレーム
間の母線を電気的に接続すればよい。When a plurality of main body frames 1a, lb of the closed switchboard integrally connected by the frame 2 are arranged in multiple rows,
The busbars 6 that pass through the side surface of the frame 2 may be used to electrically connect the busbars between the main body frames.
ｅ）発明の作用
本発明によれば、枠２が、コ字状の平断面を有するため
、それ自体断面係数が大きく、また、底部を固定するた
めに、非常に剛性が高くなる。e) Effect of the Invention According to the present invention, since the frame 2 has a U-shaped flat cross section, the section modulus itself is large, and since the bottom portion is fixed, the rigidity is extremely high.
したがって、このコ字状の凹部内に閉鎖配電盤の本体フ
レームｌａ、１ｂを一体的に結合すると、地震力による
閉鎖配電盤の変形量も最小限におさえることができる。Therefore, by integrally connecting the main body frames la and 1b of the closed switchboard in this U-shaped recess, the amount of deformation of the closed switchboard due to seismic force can be minimized.
さらに、背面側の扉５を枠２に設けたため、保守、点検
のためのスペースも十分に得ることができる。Furthermore, since the rear door 5 is provided in the frame 2, sufficient space for maintenance and inspection can be obtained.
ｆ）他の実施例
上記実施例では、二面分の枠を設けたが、場合によって
は欄、あるいは三面分でもよい。f) Other Embodiments In the above embodiments, a frame for two pages is provided, but depending on the case, a frame for two pages or a frame for three pages may be provided.
ｇ）総合的な効果
本発明によれは鋼板製パネル等の標準の閉鎖配電盤用の
本体フレームを使用して容易に耐震性のすぐれた閉鎖配
電盤が得られるだけではなく、枠を設けたことによる作
業性の低下も最小限に押さえることができるなど多くの
利点を有する閉鎖配電盤を得ることができる。g) Overall effect The present invention not only allows a closed switchboard with excellent earthquake resistance to be easily obtained by using a standard body frame for a closed switchboard such as a steel plate panel, but also provides a frame. It is possible to obtain a closed switchboard having many advantages such as being able to minimize the decrease in work efficiency.
