この発明は地震などの外力による影響を防止し
た電気機器の固定装置およびその据付方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for electrical equipment that prevents the influence of external forces such as earthquakes, and a method for installing the same.

６とにより構成されている。 Conventionally, there have been devices of this type as shown in FIGS. 1 and 2. In the figure, 1 is an electric device such as a transformer or a reactor, and 2 is a fixing device for fixing the electric device 1 to the foundation 3, which includes a foundation bolt 4 buried in the foundation 3 and the bottom side of the electric device. The fixing fitting 5 is connected to the base bolt 4, and the bolt 6 is screwed into the foundation bolt 4 to hold the fixing fitting 5.

大きい穴があけられている。 That is, a foundation bolt 4 embedded in the foundation 3 and a fixture 5 connected to an electrical device 1 such as a transformer or a reactor are tightened and fixed with bolts 6. This fixing fitting 5 has a hole larger than the diameter of the bolt 6 so that the bolt 6 can pass freely through the hole.

本数が必要となる等、欠点があつた。 By providing such fixing devices 2 at 4 locations (4 corners), 6 locations, or 8 locations on electrical equipment 1 such as a transformer or reactor, it is possible to prevent overturning or movement due to an earthquake. In this case, there is no problem with overturning if you select the diameter and number of bolts that act equally on the bolts on one side (half of the fixing device) and overcome the overturning force, but if the bolts move in the radial direction (lateral sliding force) ), it is impossible for the bolts 6 to share the force equally depending on the bolt diameter and the diameter of the hole in the fixing metal fitting 5, and it is necessary to cope with the shearing force of one bolt 6. Of course, there is no problem if the tightening force of bolt 6 is used, but in this case, generally the bolt diameter is huge,
There were drawbacks, such as the need for a large number of tubes.
この発明は上記従来装置の欠点を解消するため
になされたもので、ボルトと固定金具とがボルト

分担し得る電気機器の固定装置およびその据付方
法を提供することを目的としている。 This invention was made in order to eliminate the drawbacks of the above-mentioned conventional devices.By preventing the bolt and the fixing fitting from shifting in the radial direction of the bolt, each bolt is equally distributed against lateral slipping force. The purpose of the present invention is to provide a fixing device for electrical equipment that can share the load between the two, and a method for installing the same.
以下、この発明の一実施例を図に基づいて説明
する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.
第３図において、１，３，４は上記従来のもの

パー付ボルトで、このテーパー部がボルトが締付
けられた状態において固定金具５ａのテーパー穴
と完全に接触してボルトの半径方向ズレが阻止さ
れる構造になつている。 In FIG. 3, numerals 1, 3, and 4 are the same as the conventional one. 5a is a fixing metal fitting whose bolt hole is machined into a tapered shape, 6a is a tapered bolt, and when the bolt is tightened, this tapered part completely contacts the tapered hole of the fixing metal fitting 5a, and the radius of the bolt is adjusted. It has a structure that prevents misalignment.
このように本実施例によれば、全てのボルトが
横スベリ力に対し、等分に負荷を分担する形とな

経済的かつ安定した固定装置を得ることが可能と
なる。 In this way, according to this embodiment, all the bolts share the load evenly against the lateral sliding force, and the appropriate diameter and number of bolts can be selected, making it possible to create a more economical and stable fixing device than in the past. It becomes possible to obtain.

までもない。 In addition, in the above embodiment, the bolt 6a and the fixture 5a
The explanation has been made on the case where the radial displacement of the bolt is prevented by contacting in a tapered shape, but if the bolt 6b and the fixing metal fitting 5b are in contact with each other in a reamed shape as shown in FIG. It goes without saying that the same effect can be achieved even if the bolt 6c and the fixture 5c are fixed by welding 7 as shown in the figure.
次に、本装置の据付方法について説明する。 Next, the installation method of this device will be explained.

１、固定金具５と基礎ボルト４との位置精度等の
問題は解消される。 If the foundation bolts 4 embedded in the foundation 3 are embedded during foundation construction, embedding dimensional accuracy is required, and installation of the fixing device becomes difficult due to variations in the manufacturing dimensions of the electrical equipment 1 and installation dimensional errors. . For this purpose, as shown in Figs. 3 to 5, box-cut portions 8 are provided in advance in the foundation 3 at the positions where the foundation bolts 4 are buried, and the foundation bolts 4 are inserted into these portions and fixed. After assembling the device 2 and connecting it to the electrical equipment 1, concrete 9 is placed in the box cutout 8.
By taking the step of injecting and burying the foundation bolts 4 in the foundation 3, installation problems, such as the positional accuracy of the electric equipment 1, the fixing fittings 5, and the foundation bolts 4, are solved.

消されるという効果がある。 As described above, according to the present invention, a fixing metal fitting connected to a device and a bolt for fixing this fixing metal fitting to a foundation bolt are connected to each other so that they do not shift in the radial direction. Because of this structure, each bolt can equally share the load against lateral sliding force, and stable fixation can be achieved with the optimum bolt diameter and number. Additionally, the installation method involves inserting foundation bolts into pre-prepared box cutouts, assembling the fixing device, and then pouring concrete at the end, which eliminates problems with positional accuracy during installation. There is an effect.
