Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 鉄道線路を敷設する場合の基準点を設置する に必要な通り測定を簡単に行なうことができる通り測定 装置と、この通り測定装置を基準点に対して簡単に取付 けることができる取付治具を提案する。 【構成】 線路の予定線に沿って複数の基準器を設置す ると共に、この基準器の通りを測定するための弦の一端 に該当する基準点にレーザ光源を設置し、弦の他端に該 当する基準点にターゲットを設置し、レーザ光源から発 射したレーザビームにより弦を構成し、この弦の中間位 置に基準点から突出させた通り測定尺を設け、この通り 測定尺上に取付けた受光器によりレーザビームを受光さ せることにより、通り測定値を得る。 (57) [Abstract] [Purpose] A measuring device that can easily perform the measurement required to set a reference point when laying a railroad track, and a measuring device that can easily measure the same as the reference point. We propose a mounting jig that can be mounted. [Structure] A plurality of reference devices are installed along the planned line of the line, and a laser light source is installed at a reference point corresponding to one end of the string for measuring the street of the reference device and corresponding to the other end of the string. A target is installed at a reference point, a string is constructed by a laser beam emitted from a laser light source, a measuring scale is provided at an intermediate position of this string as it protrudes from the reference point, and a light receiver mounted on the measuring scale as such By receiving the laser beam by the, the measured value is obtained.
