Description

本発明は、測定装置に関し、特に、建築仕上材や地下構造物の表面の水分を計測する測定装置に関するものである。   The present invention relates to a measuring apparatus, and more particularly to a measuring apparatus that measures moisture on the surface of building finishing materials and underground structures.

建築仕上材、例えば、天井に用いる吸音板が漏水により水を多く含むと、接着剤の効果が落ち、落下する危険性が生じる畏れがある。また、地下構造物、例えば、地下の駅などでは、天井や壁面にクラック等が発生すると水が浸みだし構造物に悪影響を与えたり水漏れが発生する。一般に、地下構造物表面の水分を計測する場合、作業員が水分計を手に持ち測定するようにしているが、高い所を測定する場合、脚立や梯子を使用しながら測定面に電極を直角に押し当てて測定していた。しかしながら、係る測定方法では、作業効率が悪いという問題があった。このような問題を解決するため、伸縮ロッドの先端に水分計のセンサを取り付け、このセンサの向きを遠隔操作により調整するようにした装置が知られている（特許文献１参照）。
特開平８−２７１４５９号公報（第２頁、図１および図４） When a building finishing material, for example, a sound absorbing plate used for a ceiling contains a lot of water due to water leakage, the effect of the adhesive is reduced, and there is a risk that a risk of falling will occur. In an underground structure, for example, an underground station, if a crack or the like occurs on a ceiling or a wall surface, water starts to leak, causing adverse effects on the structure or causing water leakage. Generally, when measuring moisture on the surface of an underground structure, an operator holds the moisture meter in his hand, but when measuring high places, the electrode is placed perpendicular to the measurement surface using a stepladder or ladder. To measure. However, such a measuring method has a problem that work efficiency is poor. In order to solve such a problem, there is known an apparatus in which a sensor of a moisture meter is attached to the tip of a telescopic rod and the direction of the sensor is adjusted by remote operation (see Patent Document 1).
JP-A-8-271459 (second page, FIGS. 1 and 4)

しかしながら、上記従来の測定装置では、伸縮ロッドの先端にセンサを取り付け、ロッドから延長した接続コードを介して水分計で計測するようにしているので、測定時、少なくともロッドを操作する作業員と、水分計を計測する作業員とが必要になるという問題がある。測定位置を移動する場合など、ロッドと水分計とを持ち運ぶだけでなく、ロッド内に挿通されロッド下端から外部に伸びる接続コードをも引き回しながら移動するようにしている。このため、移動するたびに接続コードに注意しながら移動しなければならず作業性が悪いという問題があった。また、接続コードを伸縮ロッド内に挿通させているため、ロッドが大径となって重量化し、作業しにくくなる。さらに、伸縮ロッド自体を長寸化すると、短くして使用する場合、外部に露出する接続コードが長くなってしまい、移動に難渋するという問題がある。また、測定を続けて行う場合、センサの電極ピンが次第に汚れ、測定精度が落ちるため、複数回の測定毎電極ピンの汚れを清浄な布で拭き取らなければならず、作業性が悪いという問題がある。   However, in the conventional measuring apparatus, a sensor is attached to the tip of the telescopic rod, and the moisture meter is configured to measure through a connection cord extending from the rod.At the time of measurement, at least an operator operating the rod, There is a problem that a worker who measures the moisture meter is required. When moving the measurement position, not only the rod and moisture meter are carried, but also the connection cord that is inserted into the rod and extends from the lower end of the rod is moved while being routed. For this reason, there is a problem in that workability is poor because it is necessary to move while paying attention to the connection cord every time it moves. Further, since the connecting cord is inserted into the telescopic rod, the rod becomes large in diameter and becomes heavy, making it difficult to work. Furthermore, when the length of the telescopic rod itself is increased, the connection cord exposed to the outside becomes longer when used with a shorter length, which makes it difficult to move. In addition, when performing measurement continuously, the electrode pins of the sensor are gradually soiled, and the measurement accuracy is lowered. Therefore, the electrode pins must be wiped off with a clean cloth after each measurement, resulting in poor workability. There is.

本発明は、上記課題を解決するためになされたもので、簡素な構成で移動時あるいは作業時の作業効率を向上させ、使い勝手の良好な測定装置を提供することを目的とするものである。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a measuring device that is easy to use and improves work efficiency during movement or work with a simple configuration.

本発明に係る測定装置は、伸縮ロッドの先端に、測定器と電気的に接続されるセンサが取り付けられた測定装置において、上記先端に設けられ、センサが取り外し自在に装着されるとともにセンサの姿勢を調整可能な装着部と、伸縮ロッドの基部に設けられ、測定器が保持される保持部と、両端側が伸縮ロッドの先端と基部とにそれぞれ固定され、センサと測定器との間を接続する伸縮自在な接続コードとを備えるとともに、接続コードを伸縮ロッドに沿って支持する支持部材を設けるようにしたものである。   The measuring device according to the present invention is a measuring device in which a sensor electrically connected to a measuring instrument is attached to the tip of a telescopic rod. The adjustable mounting part, the holding part provided at the base of the telescopic rod, the measuring instrument is held, and both ends are fixed to the tip and the base of the telescopic rod, respectively, to connect between the sensor and the measuring instrument And a support member that supports the connection cord along the extendable rod.

本発明に係る測定装置では、伸縮ロッドの先端に、測定器と電気的に接続されるセンサが取り付けられた測定装置であって、上記先端に設けられ、センサが取り外し自在に装着されるとともにセンサの姿勢を調整可能な装着部と、伸縮ロッドの基部に設けられ、測定器が保持される保持部と、両端側が伸縮ロッドの先端と基部とにそれぞれ固定され、センサと測定器との間を接続する伸縮自在な接続コードとを備えるとともに、接続コードを伸縮ロッドに沿って支持する支持部材を設けたことにより、作業を行うときには、センサを装着部に取り付け接続コードの先端側端部と接続し、保持部に測定器を装着して接続コードの基部側端部と接続し、測定すべき面の高さに応じて伸縮ロッドを伸ばすと、接続コードは支持部材により伸縮ロッドの伸びに応じて伸縮ロッドに沿って伸びる。伸縮ロッドを伸ばした状態から縮めると、接続コードは伸縮ロッドに沿って縮む。また、センサは測定すべき面の傾斜に応じて自在に姿勢を調整することができるので、測定面に正確にセンサを当てることができる。移動する際、伸縮ロッドを持ち運ぶだけで、接続コードも測定器も伸縮ロッドと一体に運ぶことができるので、作業性が向上する。さらに、接続コードを伸縮ロッドの外部に配置しているので、伸縮ロッドを細径化して軽量化を図ることができる。接続コードは常に伸縮ロッド側に沿って支持されるので、伸縮しても垂れ下がって作業の邪魔をすることがないので作業性が向上する。   The measuring device according to the present invention is a measuring device in which a sensor electrically connected to a measuring instrument is attached to the tip of the telescopic rod, and the sensor is provided at the tip and is detachably attached to the sensor.

Then, attach the measuring instrument to the holding part and connect it to the base side end of the connection cord, and extend the telescopic rod according to the height of the surface to be measured. Extending along the stretch rod in response to the growth. When the telescopic rod is retracted from the stretched state, the connecting cord contracts along the telescopic rod. Further, since the posture of the sensor can be freely adjusted according to the inclination of the surface to be measured, the sensor can be accurately applied to the measurement surface. When moving, just by carrying the telescopic rod, the connection cord and measuring instrument can be carried together with the telescopic rod, improving workability. Furthermore, since the connecting cord is arranged outside the telescopic rod, the telescopic rod can be made thinner to reduce the weight. Since the connection cord is always supported along the telescopic rod side, the workability is improved because it does not hinder the work even if it extends and contracts.

また、請求項２に係る測定装置は、保持部を筒状体から構成し、その内部には測定器を保持する弾性部材を取り付けるとともに、この筒状体の出し入れ側には測定器の脱落を阻止する押さえ板を設けるようにしたものである。   Further, in the measuring apparatus according to claim 2, the holding portion is constituted by a cylindrical body, and an elastic member for holding the measuring instrument is attached to the inside of the holding section, and the measuring instrument is dropped on the side of the cylindrical body. A holding plate for blocking is provided.

請求項２に係る測定装置では、保持部を筒状体から構成し、その内部には測定器を保持する弾性部材を取り付けるとともに、この筒状体の出し入れ側には測定器の脱落を阻止する押さえ板を設けるようにしたので、作業時、伸縮ロッドの姿勢がたとえ上下逆になっても、測定器は弾性部材により保持されるので脱落しにくく、また、衝撃を受けても弾性部材により衝撃が緩和され保護される。また、たとえ衝撃を受けても、押さえ板は測定器が外部に脱落するのを阻止するので、機器の保全を図ることができる。このため、たとえ伸縮ロッドが手から滑り落ちても、測定器は筒状体と弾性部材により保護されるので破損しにくい。   In the measuring apparatus according to claim 2, the holding portion is formed of a cylindrical body, and an elastic member for holding the measuring instrument is attached to the inside of the holding section, and the measuring instrument is prevented from dropping out of the cylindrical body. Since the holding plate is provided, the measuring instrument is held by the elastic member even when the telescopic rod is turned upside down during work, so it will not fall off easily. Is relaxed and protected. In addition, even if an impact is received, the holding plate prevents the measuring device from dropping out, so that the equipment can be maintained. For this reason, even if the telescopic rod slides down from the hand, the measuring instrument is protected by the cylindrical body and the elastic member, and is not easily damaged.

請求項３に係る測定装置は、測定器は水分を測定する水分計により、センサは本体から外部に突出した一対の電極ピンを備えた水分センサによりそれぞれ構成されるとともに、センサには、電極ピンに装着され電極ピンの汚れを吸着する清掃カバーが取り付けられるようにしたものである。   According to a third aspect of the present invention, the measuring device is constituted by a moisture meter for measuring moisture, and the sensor is constituted by a moisture sensor provided with a pair of electrode pins protruding outward from the main body. A cleaning cover that is attached to and adsorbs dirt on the electrode pins is attached.

Since the cleaning cover that attaches to the electrode pin and absorbs dirt on the electrode pin can be attached, the dirt on the electrode pin can be removed simply by attaching and removing the cleaning cover to the electrode pin of the sensor every appropriate number of measurements. Measurement accuracy can be maintained in the work.

本発明に係る測定装置は、伸縮ロッドの先端に、測定器と電気的に接続されるセンサが取り付けられた測定装置において、上記先端に設けられ、センサが取り外し自在に装着されるとともにセンサの姿勢を調整可能な装着部と、伸縮ロッドの基部に設けられ、測定器が保持される保持部と、両端側が伸縮ロッドの先端と基部とにそれぞれ固定され、センサと測定器との間を接続する伸縮自在な接続コードとを備えるとともに、接続コードを伸縮ロッドに沿って支持する支持部材を設けるようにしているので、簡素な構成で移動時あるいは作業時の作業性を向上させることができる。   The measuring device according to the present invention is a measuring device in which a sensor electrically connected to a measuring instrument is attached to the tip of a telescopic rod.

以下、図面に示す実施の形態により本発明を説明する。図１は本発明の一実施の形態に係る測定装置の全体図である。本実施の形態に係る測定装置２は、図１に示すように、大径の円管状基部３とこの基部３内にそれぞれ径に応じて順に収容される小径の中間筒４と先端筒５とを有する伸縮ロッド６を備えている。伸縮ロッド６は先端筒５が中間筒４に、中間筒４が基部３の内部にそれぞれ収容される。基部３と中間筒４との間、中間筒４と先端筒５との間には、それぞれ締め付け具７、７が設けられる。伸縮ロッド６は、この締め付け具７、７を緩めて先端筒５と中間筒４とのうち少なくともいずれか一方を先端側に所望の長さ引き出し、締め付け具７、７を締め付けると、伸縮ロッド６を所望の長さに設定できるようになっている。基部３は管状部３Ａとその管状部３Ａの外周に形成された合成樹脂製発泡体からなる大径の握り部３Ｂ、３Ｃとからなっている。   The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is an overall view of a measuring apparatus according to an embodiment of the present invention. As shown in FIG. 1, the measuring device 2 according to the present embodiment includes a large-diameter circular tubular base 3, a small-diameter intermediate cylinder 4 and a distal-end cylinder 5 that are sequentially accommodated in the base 3 according to the diameter. The telescopic rod 6 having The telescopic rod 6 is housed in the intermediate tube 4 at the distal end tube 5 and inside the base 3, respectively. Fastening tools 7 and 7 are provided between the base 3 and the intermediate cylinder 4 and between the intermediate cylinder 4 and the tip cylinder 5, respectively. The telescopic rod 6 is loosened by loosening the fasteners 7 and 7 and pulling out at least one of the distal end tube 5 and the intermediate tube 4 to the distal end side and tightening the fasteners 7 and 7. Can be set to a desired length. The base 3 includes a tubular portion 3A and large-diameter grip portions 3B and 3C made of a synthetic resin foam formed on the outer periphery of the tubular portion 3A.

先端筒５の頂部には、Ｔ字状の装着部８が取り外し自在に設けられる。この装着部８は、図２に示すように、断面Ｃ字状の半割状部８Ａとこの半割状部８Ａの下面から下方に延びるねじ部８Ｂとにより構成される。このねじ部８Ｂは先端筒５上端のねじ穴５Ａに螺装される。装着部８の半割状部８Ａは伸縮ロッド６の軸心に対して直角になっている。この半割状部８Ａには、水分計（測定器）１０（図３参照）の水分センサ（センサ）９が取り外し自在に装着されるようになっている。水分センサ９は、本体の上端面に突出して設けられた一対の電極ピン１１Ａ、１１Ｂを備えている。この水分センサ９の下部は円柱状に形成される。この円柱状部１２は、半割状部８Ａに圧入されるようになっている。このため、水分センサ９を半割状部８Ａに装着し、水分センサ９を押し回すと押し回した角度でその姿勢を変えられるようになっている。すなわち、水分センサ９は伸縮ロッド６の軸心に対して直角方向を回動中心として所望の角度で傾斜させた状態を保つことができるようになっている。水分センサ９の円柱状部１２の一端は半球状に、他端は次第に縮径する円錐状に形成され、この円錐状部から接続端子１３が伸びている。   A T-shaped mounting portion 8 is detachably provided on the top of the tip tube 5. As shown in FIG. 2, the mounting portion 8 includes a half-shaped portion 8A having a C-shaped cross section and a screw portion 8B extending downward from the lower surface of the half-shaped portion 8A. This threaded portion 8B is screwed into the screw hole 5A at the upper end of the distal end tube 5. The half-shaped part 8 </ b> A of the mounting part 8 is perpendicular to the axis of the telescopic rod 6. A moisture sensor (sensor) 9 of a moisture meter (measuring instrument) 10 (see FIG. 3) is detachably attached to the halved portion 8A. The moisture sensor 9 includes a pair of electrode pins 11A and 11B provided to protrude from the upper end surface of the main body. The lower part of the moisture sensor 9 is formed in a cylindrical shape. The cylindrical portion 12 is press-fitted into the half-shaped portion 8A. For this reason, when the moisture sensor 9 is attached to the half-shaped portion 8A and the moisture sensor 9 is pushed and turned, the posture can be changed by the pushed angle. That is, the moisture sensor 9 can maintain a state in which the moisture sensor 9 is inclined at a desired angle with the direction perpendicular to the axis of the telescopic rod 6 as the rotation center. One end of the cylindrical portion 12 of the moisture sensor 9 is formed in a hemispherical shape, and the other end is formed in a conical shape with a gradually decreasing diameter, and the connection terminal 13 extends from the conical portion.

水分センサ９の上端には、汚れを吸着する合成樹脂製発泡体からなる掃除カバー１４が被せられるようになっている。掃除カバー１４には、電極ピン１１Ａ、１１Ｂが差し入れられる掃除孔１５Ａ、１５Ｂが形成される。この掃除カバー１４は、水分センサ９上端に被せられると、掃除孔１５Ａ、１５Ｂに電極ピン１１Ａ、１１Ｂが差し入れられ電極ピン１１Ａ、１１Ｂの汚れを吸着するようになっている。このように、掃除カバー１４を電極ピン１Ａ、１１Ｂに装着するだけで汚れが取れるので、電極ピン１１Ａ、１１を常に良好な状態に保持できる。また、水分センサ９には、掃除カバー１４が被せられると、電極ピン１１Ａ、１１Ｂを保護するキャップ１６が被せられるようになっている。このキャップ１６は硬質の合成樹脂からなり、水分センサ９の上部に嵌るようになっている。水分計１０は、図３に示すように、上部１０Ａが幅広で下部１０Ｂが幅狭の角筒状に形成され、上面に表示部１０Ｃが形成される。幅広上部１０Ａの一側部には、水分センサ９と接続される接続端子１０Ｄが設けられる。   The upper end of the moisture sensor 9 is covered with a cleaning cover 14 made of a synthetic resin foam that adsorbs dirt. The cleaning cover 14 is formed with cleaning holes 15A and 15B into which the electrode pins 11A and 11B are inserted. When the cleaning cover 14 is put on the upper end of the moisture sensor 9, the electrode pins 11A and 11B are inserted into the cleaning holes 15A and 15B so as to adsorb dirt on the electrode pins 11A and 11B. As described above, since the dirt is removed only by attaching the cleaning cover 14 to the electrode pins 1A and 11B, the electrode pins 11A and 11 can always be kept in a good state. Further, when the cleaning cover 14 is put on the moisture sensor 9, a cap 16 that protects the electrode pins 11A and 11B is put on the moisture sensor 9. The cap 16 is made of a hard synthetic resin and is fitted on the upper part of the moisture sensor 9. As shown in FIG. 3, the moisture meter 10 is formed in a rectangular tube shape in which the upper portion 10 </ b> A is wide and the lower portion 10 </ b> B is narrow, and the display portion 10 </ b> C is formed on the upper surface. A connection terminal 10D connected to the moisture sensor 9 is provided on one side of the wide upper portion 10A.

伸縮ロッド６の基部３には、上下の握り部３Ｂ、３Ｃ間に水分計１０を納める保持部２０が設けられる。保持部２０は水分計１０を脱落しないように保持するようになっている。保持部２０は、図４に示すように、管状部３Ａに固定された角箱部２１の対向する側面にそれぞれ取り付けられた断面Ｌ字状折曲プレート２２Ａ、２２Ｂと、これら折曲プレート２２Ａ、２２Ｂの折曲端間に取り付けられた合成樹脂からなる透明プレート２３とを備えている。透明プレート２３には、円形の穴２４が形成される。これら角箱部２１と折曲プレート２２Ａ、２２Ｂと透明プレート２３とにより水分計１０を納める筒状体を構成している。   The base 3 of the telescopic rod 6 is provided with a holding unit 20 that houses the moisture meter 10 between the upper and lower grips 3B and 3C. The holding unit 20 holds the moisture meter 10 so as not to drop off. As shown in FIG. 4, the holding portion 20 includes L-shaped bent plates 22A and 22B attached to opposite side surfaces of the square box portion 21 fixed to the tubular portion 3A, and these bent plates 22A, And a transparent plate 23 made of synthetic resin attached between the bent ends of 22B. A circular hole 24 is formed in the transparent plate 23. The rectangular box portion 21, the bent plates 22A and 22B, and the transparent plate 23 constitute a cylindrical body that houses the moisture meter 10.

この筒状の保持部２０内部には、角箱部２１と折曲プレート２２Ａ、２２Ｂとに合成樹脂製発泡体からなる弾性部材２５が取り付けられ、水分計１０が内部に納められると弾性変形して保持し脱落させないようになっている。保持部２０の上部開口の角箱部２１側上端部には、押さえ板２６が傾斜して取り付けられる。押さえ板２６は外部の力で撓むようになっており、伸縮ロッド６が衝撃を受けても水分計１０が容易に脱落しないようになっている。この保持部２０には、上部開口から水分計１０を出し入れするようになっている。この保持部２０に水分計１０を納めると、伸縮ロッド６を操作する作業員が水分センサ９を測定部位に押し当てたまま、同時に水分計１０の計測値を読み取ることができる。   Inside this cylindrical holding part 20, an elastic member 25 made of a synthetic resin foam is attached to the square box part 21 and the bent plates 22A, 22B, and when the moisture meter 10 is housed inside, it elastically deforms. And keep it from falling off. A holding plate 26 is attached to the upper end of the upper opening of the holding part 20 on the side of the square box part 21 in an inclined manner. The pressing plate 26 is bent by an external force so that the moisture meter 10 does not easily fall off even when the telescopic rod 6 receives an impact. The moisture meter 10 is taken into and out of the holding portion 20 from the upper opening. When the moisture meter 10 is stored in the holding unit 20, an operator operating the telescopic rod 6 can simultaneously read the measurement value of the moisture meter 10 while pressing the moisture sensor 9 against the measurement site.

先端筒５の上部には、図１に示すように、水分センサ９と水分計１０とを接続する螺旋状に形成された接続コード３０の一端が、また、基部３の保持部２０上部には、その接続コード３０の他端近傍が拘束具３１、３２によりそれぞれ固定される。接続コード３０は螺旋状に形成されているので、伸縮するようになっている。また、接続コード３０の先端筒５側端子は水分センサ９の端子１３に、接続コード３０の基部３側端子は水分計１０の端子１０Ｄにそれぞれ接続されるようになっている。   As shown in FIG. 1, one end of a connection cord 30 formed in a spiral shape that connects the moisture sensor 9 and the moisture meter 10 is formed at the upper portion of the tip tube 5, and the holding portion 20 of the base 3 is disposed at the upper portion of the holding tube 20. The vicinity of the other end of the connection cord 30 is fixed by the restraining tools 31 and 32, respectively. Since the connection cord 30 is formed in a spiral shape, the connection cord 30 can be expanded and contracted. Further, the terminal tube 5 side terminal of the connection cord 30 is connected to the terminal 13 of the moisture sensor 9, and the base 3 side terminal of the connection cord 30 is connected to the terminal 10D of the moisture meter 10, respectively.

伸縮ロッド６には、図１に示すように、所定の間隔をおいて複数の支持部材３３が取り付けられる。すなわち、接続コード３０の伸縮の状態に関係なく弛むことがないように、伸縮ロッドの最大伸長時、各支持部材３３がそれぞれ、基部３、中間筒４および先端筒５の各ロッド部と接続コード３０とを結んで係止するよう配置されている。この支持部材３３は、図５に示すように、接続コード３０に挟み付けられる固定具３４と、この固定具３４の開口部３５に挿通され伸縮ロッド６に遊びを持って掛け回された環状部材３６とにより構成される。伸縮ロッド６と接続コード３０との間には、支持部材３３が取り付けられているので、伸縮ロッド６の伸縮に応じて接続コード３０が伸縮しても支持部材３３は接続コード３０を常に伸縮ロッド６側に沿って支持するので、接続コード３０が垂れ下がって測定作業の邪魔をすることがない。   As shown in FIG. 1, a plurality of support members 33 are attached to the telescopic rod 6 at a predetermined interval. That is, each support member 33 is connected to each rod portion of the base 3, the intermediate tube 4, and the tip tube 5 and the connection cord when the telescopic rod is fully extended so that the connection cord 30 does not loosen regardless of the expansion / contraction state of the connection cord 30. 30 and is arranged to be locked. As shown in FIG. 5, the support member 33 includes a fixture 34 that is sandwiched between the connection cords 30 and an annular member that is inserted through the opening 35 of the fixture 34 and is hung around the telescopic rod 6 with play. 36. Since the support member 33 is attached between the expansion / contraction rod 6 and the connection cord 30, even if the connection cord 30 expands / contracts according to the expansion / contraction of the expansion / contraction rod 6, the support member 33 always attaches the connection cord 30 to the expansion / contraction rod. Since it is supported along the 6 side, the connection cord 30 does not hang down and interfere with the measurement operation.

次に、上記実施の形態に係る測定装置２の作用について説明する。この測定装置２は、例えば、地下駅の壁面等の構造物について作業を行う際、まず、掃除カバー１４とキャップ１６が被せられた水分センサ９を、装着部８に取り付ける。取り付けは水分センサ９の円柱状部１２を半割状部８Ａに押し込んで行う。次に、水分センサ９の端子１３を接続コード３０の先端筒５側端子に接続する。次に、測定すべき面の高さに応じて伸縮ロッド６を伸ばして締め付け具７を締め付ける。測定すべき面が傾斜している場合、傾斜角度に応じて、水分センサ９を押し回して傾斜させると、その姿勢が保持される。次に、保持部２０に水分計１０を装着し、接続コード３０の基部３側端子を水分計１０の端子１０Ｄに接続し、掃除カバー１４とキャップ１６を取り外して測定を行う。測定は、測定すべき面に水分センサ９の両電極ピン１１Ａ、１１Ｂを押し当てて行われる。   Next, the operation of the measuring apparatus 2 according to the above embodiment will be described. For example, when the measuring device 2 performs a work on a structure such as a wall surface of an underground station, first, the moisture sensor 9 covered with the cleaning cover 14 and the cap 16 is attached to the mounting portion 8. Attachment is performed by pushing the cylindrical portion 12 of the moisture sensor 9 into the half-shaped portion 8A. Next, the terminal 13 of the moisture sensor 9 is connected to the terminal tube 5 side terminal of the connection cord 30. Next, the telescopic rod 6 is extended according to the height of the surface to be measured, and the tightening tool 7 is tightened. When the surface to be measured is tilted, the posture is maintained when the moisture sensor 9 is pushed and tilted according to the tilt angle. Next, the moisture meter 10 is attached to the holding unit 20, the base 3 side terminal of the connection cord 30 is connected to the terminal 10D of the moisture meter 10, and the cleaning cover 14 and the cap 16 are removed to perform measurement. The measurement is performed by pressing both electrode pins 11A and 11B of the moisture sensor 9 against the surface to be measured.

測定時、測定すべき面の高さに応じて伸縮ロッド６を伸縮させると、接続コード３０は伸縮ロッド６の伸縮に応じて伸縮する。しかも、接続コード３０は支持部材３３により伸縮ロッド６側に拘束されているので、垂れ下がることがない。また、水分センサ９は測定すべき面の傾斜に応じて自在に姿勢を調整することができるので、測定面に正確に水分センサ９を当てることができる。さらに、測定時、伸縮ロッド６を操作する作業員が手で基部３を持ち、水分センサ９を測定部位に押し当てたまま、同時に水分計１０の計測値を読み取ることができるので、少人数でしかも効率的に測定を行うことができる。移動する際、伸縮ロッド６を持ち運ぶだけで、接続コード３０も水分計１０も伸縮ロッド６と一体に運ぶことができるので、作業性が向上する。さらに、接続コード３０を伸縮ロッド６の外部に配置しているので、伸縮ロッド６を細径化して軽量化を図ることができ、作業員の疲労を緩和することができる。   At the time of measurement, when the telescopic rod 6 is expanded and contracted according to the height of the surface to be measured, the connection cord 30 expands and contracts according to the expansion and contraction of the telescopic rod 6. Moreover, since the connection cord 30 is restrained to the telescopic rod 6 side by the support member 33, it does not hang down. Further, since the moisture sensor 9 can freely adjust its posture according to the inclination of the surface to be measured, the moisture sensor 9 can be accurately applied to the measurement surface. Furthermore, at the time of measurement, the operator who operates the telescopic rod 6 holds the base 3 by hand and can simultaneously read the measurement value of the moisture meter 10 while pressing the moisture sensor 9 against the measurement site. In addition, the measurement can be performed efficiently. Since the connecting cord 30 and the moisture meter 10 can be carried together with the telescopic rod 6 simply by carrying the telescopic rod 6 when moving, workability is improved. Furthermore, since the connection cord 30 is arranged outside the telescopic rod 6, the telescopic rod 6 can be reduced in diameter to reduce the weight, and worker fatigue can be reduced.

また、保持部２０には、弾性部材２５と押さえ板２６が取り付けられているため、水分計１０は、衝撃を受けても容易に外部に脱落することがなく、衝撃も緩和することができる。また、適当な測定回数毎水分センサ９の電極ピン１１Ａ、１１Ｂに掃除カバー１４を付け外すだけで電極ピン１１Ａ、１１Ｂの汚れを取り除くことができるので、簡単な作業で測定精度を維持することができる。移動時、キャップ１６を水分センサ９に取り付けておけば、万一、水分センサ９が構造物に当たっても破損を防ぐことができる。   In addition, since the elastic member 25 and the pressing plate 26 are attached to the holding unit 20, the moisture meter 10 does not easily fall outside even when receiving an impact, and the impact can be reduced. Further, since the dirt on the electrode pins 11A and 11B can be removed by simply attaching and removing the cleaning cover 14 to the electrode pins 11A and 11B of the moisture sensor 9 at an appropriate number of times of measurement, the measurement accuracy can be maintained with a simple operation. it can. If the cap 16 is attached to the moisture sensor 9 during movement, damage can be prevented even if the moisture sensor 9 hits the structure.

なお、上記実施例では、装着部８はＴ字状に形成され、水分センサ９は伸縮ロッド６軸心に対して直角方向を回動中心として姿勢を変更することができるようになっているが、これに限られるものではなく、半割状部８Ａに対してねじ部８Ｂを傾斜可能に設け、半割状部８Ａを伸縮ロッド６の軸心に対して傾斜させ、姿勢をどの角度にも調整できるようにしてもよい。また、保持部２０は市販されている種々の水分計の形状に合わせて形成するようにしてもよいし、筒状体に限らず、水分計を基部３に保持するものであればよい。さらに、支持部材３３は、上記実施の形態に限られるものではなく、伸縮ロッド６と螺旋状接続コード３０とに取り付けられ、ロッド６やコード３０の伸縮に関係なく、接続コード３０を伸縮に関係なく常に伸縮ロッド６側に沿って支持するものであればよいことはいうまでもない。また、装着部８のねじ部８Ｂを先端筒５上端のねじ穴５Ａに螺装しているが、非使用時には、装着部８を先端筒５から取り外して管理し、円形頭部を有するねじをねじ穴５Ａに螺装するようにしておいてもよい。   In the above embodiment, the mounting portion 8 is formed in a T-shape, and the moisture sensor 9 can change its posture with the direction perpendicular to the axis of the telescopic rod 6 as the center of rotation. However, the present invention is not limited to this, and the threaded portion 8B can be inclined with respect to the half-shaped portion 8A, the half-shaped portion 8A is inclined with respect to the axis of the telescopic rod 6, and the posture can be set at any angle. It may be possible to adjust. Further, the holding unit 20 may be formed in accordance with the shape of various commercially available moisture meters, and is not limited to a cylindrical body, and may be any device that holds the moisture meter on the base 3. Further, the support member 33 is not limited to the above embodiment, and is attached to the telescopic rod 6 and the helical connection cord 30, and the connection cord 30 is related to the expansion and contraction regardless of the expansion and contraction of the rod 6 and the cord 30. Needless to say, it is only necessary to always support the telescopic rod 6 along the side. Further, the threaded portion 8B of the mounting portion 8 is screwed into the screw hole 5A at the upper end of the distal end tube 5. However, when not in use, the mounting portion 8 is removed from the distal end tube 5 for management, and a screw having a circular head is used. The screw hole 5A may be screwed.
