Abstract

【課題】特別な技術を必要とせず、鉄道用枕木の床板取付け用螺釘の穿孔センターを、誰でも簡単に１００％正確に位置出しできる工具を提供する。
【解決手段】橋の上等で、床板を枕木に固定する螺釘を打つ孔を枕木に穿つもので、円筒状の本体の中央に孔を設け、辺部に数個のマグネットを円形になるように設ける。円筒状の本体の下に小さな円筒状の部分を設け、これは予め設けた床板の孔に嵌る。これにより、本体の中央の孔にドリルが床板の孔を通って下の枕木に当てられる。その孔にドリルを当てることにより誰でも垂直に枕木にドリル孔を穿つことができる。マグネットは鉄である床板に接着し、本体の危険な落下を防ぐ。
【選択図】図１PROBLEM TO BE SOLVED: To provide a tool which can easily and 100% accurately position a drilling center of a screw for mounting a railroad sleeper floorboard without requiring special technology.
SOLUTION: On a bridge or the like, a hole for hitting a nail for fixing a floor plate to a sleeper is made in a sleeper, a hole is provided in the center of a cylindrical main body, and several magnets are formed in a circular shape on a side portion. To be provided. Below the cylindrical body there is a small cylindrical part which fits into a hole in the pre-defined floorboard. This allows the drill to hit the lower sleeper through the hole in the floorboard into the hole in the center of the body. Anyone can drill a hole in the sleeper vertically by drilling the hole. The magnet adheres to the iron floorboard to prevent the body from falling dangerously.

Description

本考案は、鉄道用特に橋の上で枕木に正確簡単に床板取付け用センター出しをする工具に関する。 The present invention relates to a tool for centering a floor board on a railroad tie, especially on a bridge, accurately and easily.

枕木上に予め孔のあいた床板があり、その孔にのせて、ドリルを通す時に用いる治具で、従来のセンター出しの方法だと、孔をあける枕木に、目算で床板の孔の中心に合わせてポンチでマークを付け、そのマークを狙ってドリルを立て込んでいたが、床板の厚みが２ｃｍ有りマークに確実に一致させるのが困難で偏芯するため、螺釘を打ちこむときに床板の孔と螺釘が合わず垂直に打込めなかった。又、作業に時間が多くかかる。釘が斜めになると正確な枕木と床板の固定はできない。
特記すべき先行文献なし。各社のパンフレット等があるが、本考案の様なものはない。 There is a floor board with a hole in advance on the sleeper, and it is a jig used when passing a drill on the hole, and according to the conventional centering method, the center of the hole in the floor board is approximated to the sleeper to make a hole The punch was marked with a punch, and the drill was set up aiming at the mark. However, the thickness of the floor plate was 2 cm. It was difficult to match the mark with certainty. Did not fit and could not be driven vertically. In addition, it takes a lot of time to work. If the nail is slanted, it will not be possible to fix the sleeper and floorboard accurately.
No prior literature to note. There are pamphlets from each company, but nothing like this invention.

本考案は、短時間で、正確に床板取付け用センター出しをする工具を提供する。 The present invention provides a tool for accurately centering a floor plate in a short time.

本考案は、中央に孔を設けた平たい円筒状の本体の辺部に、数個のマグネットを設け、本体の円筒体の下に小さな円筒体を設け、その小さな円筒体にも中央に孔があいており、その小さな円筒体は枕木の上の床板の孔に嵌り、枕木にそれらの孔を介して、ドリルを当てることができる、ドリルガイドであるセンター出し工具に関する。 In the present invention, several magnets are provided on the side of a flat cylindrical main body having a hole in the center, a small cylindrical body is provided under the cylindrical body of the main body, and the small cylindrical body also has a hole in the center. Drilling, the small cylinder fits into holes in the floorboard above the ties, and relates to a centering tool, a drill guide, through which the ties can be drilled.

本工具により、鉄道用枕木に簡単に床板取付け用センター出しが出来るようになりすぐに準備出来る。 With this tool, the center for floorboard mounting can be easily set on the railroad sleeper, and it can be prepared immediately.

また、本工具ドリルガイドは計測の必要が無いので、技術を要せず、直ちにドリルを立てて穿孔作業に移れるということと、ドリルを正確にガイドするので、種々の優れた効果を発する。 Further, since the tool drill guide does not need to be measured, it does not require any skill, and it is possible to immediately set up a drill and proceed to a drilling operation, and since it guides the drill accurately, various advantageous effects are exhibited.

円筒体１の辺部に、円筒状に数個のマグネット２を埋め込む。円筒体の高さは小さく、平たく、下に又、小さな円筒体３を設け、これは先が嵌めやすいようにテーパー部４を持っている。小さな円筒体３を床板５の孔６に嵌める。これにより、本工具と床板は、嵌り合う。この本工具の中央の孔７にドリルを通し、枕木８に孔をあける。この孔に螺釘を通すと、床板５と枕木８はしっかり固定される。床板５は鉄製であり、マグネット２により固定され、橋の上からの危険性のある落下を防ぐ。又、治具には半円筒状の取っ手９をつけて、取り扱いやすいようにする。 Several magnets 2 are embedded in the side of the cylindrical body 1 in a cylindrical shape. The height of the cylinder is small, flat, and there is also a small cylinder 3 below, which has a tapered portion 4 for easy fitting. The small cylindrical body 3 is fitted into the hole 6 of the floor plate 5. As a result, the tool and the floor plate are fitted. A hole is made in the center hole 7 of the tool and a hole is made in the sleeper 8. When a screw is passed through this hole, the floor plate 5 and the sleeper 8 are firmly fixed. The floor plate 5 is made of iron and fixed by the magnet 2 to prevent a dangerous drop from a bridge. The jig is provided with a semi-cylindrical handle 9 for easy handling.

誰でも正確に枕木にドリルを当てられ、便利であり広く利用される可能性がある。 Anyone can accurately drill a sleeper, which is convenient and could be widely used.
