本発明は、建築物の柱や壁などの測定対象の傾きを測定する傾き測定器に関するものである。   The present invention relates to an inclination measuring instrument for measuring the inclination of a measuring object such as a pillar or wall of a building.

従来から、建築物の柱や壁などの測定対象の傾きを測定する傾き測定器が提供されている。この種の傾き測定器は、例えば建築現場で用いられる他、工事の振動や地震によって建築物が受けた被害の程度を評価する際にも用いられる。   2. Description of the Related Art Conventionally, an inclination measuring instrument that measures the inclination of a measurement object such as a pillar or wall of a building has been provided. This type of inclination measuring device is used, for example, at a construction site, and also when evaluating the degree of damage to a building due to vibration or earthquake of construction.

従来の傾き測定器の例を図７に示す。この傾き測定器は、角柱形状の柱部６１と、柱部６１の長手方向の両端部から、それぞれ柱部６１の一側面に直交する方向であって互いに同じ方向へ互いに同じ突出寸法で突設された２個の腕部６２，６３とからなるコ字形状の測定器本体６を有する。   An example of a conventional tilt measuring instrument is shown in FIG. This inclination measuring device protrudes from the prismatic column 61 and from both ends in the longitudinal direction of the column 61 in a direction perpendicular to one side surface of the column 61 and in the same direction with the same protruding dimension. The U-shaped measuring device main body 6 is composed of two arm portions 62 and 63.

上側の腕部には、一端に錘７が吊り下げられた糸８の他端が固定されている。つまり、錘７と糸８でいわゆる下げ振りが構成されており、糸８は常に鉛直方向を示す。   The other end of the thread 8 with a weight 7 suspended from one end is fixed to the upper arm. That is, the weight 7 and the thread 8 constitute a so-called downward swing, and the thread 8 always indicates the vertical direction.

また、下側の腕部６３には、腕部６３の突出方向に長い長穴（図示せず）が貫設されており、糸８は長穴に挿通され、錘７は下側の腕部６３の下側に位置している。下側の腕部６３には、糸８が長穴を通過する位置と、柱部６１の傾きとの対応関係を示す目盛（図示せず）が長穴の長手方向に沿って付されている。   The lower arm 63 has a long hole (not shown) extending in the protruding direction of the arm 63, the thread 8 is inserted through the long hole, and the weight 7 is the lower arm. 63 is located on the lower side. A scale (not shown) indicating the correspondence between the position where the thread 8 passes through the elongated hole and the inclination of the column portion 61 is attached to the lower arm 63 along the longitudinal direction of the elongated hole. .

上記従来の傾き測定器を用いて測定対象としての柱Ｐの傾きを測定するには、各腕部６２，６３の先端をそれぞれ柱Ｐに当接させることにより柱部６１の傾きと柱Ｐの傾きとを合わせる。すると、錘７の位置が安定した状態での糸８の位置の目盛が、柱Ｐの傾きを示す。
実公昭５７−１６０８６号公報 In order to measure the inclination of the column P as a measurement object using the conventional inclination measuring device, the inclination of the column part 61 and the column P are brought into contact with the ends of the arms 62 and 63 respectively. Match the tilt. Then, the scale of the position of the yarn 8 in a state where the position of the weight 7 is stable indicates the inclination of the column P.
Japanese Utility Model Publication No.57-16086

しかし、上記従来の傾き測定器では、糸に風が当たると錘の位置が安定しないため、測定対象の傾きを正確に測定することが難しいという問題があった。   However, the conventional tilt measuring instrument has a problem that it is difficult to accurately measure the tilt of the measuring object because the position of the weight is not stable when the wind hits the yarn.

本発明は上記事由に鑑みて為されたものであり、その目的は、柱の傾きを正確に測定することができる傾き測定器を提供することにある。   This invention is made | formed in view of the said reason, The objective is to provide the inclination measuring device which can measure the inclination of a column correctly.

請求項１の発明は、建築物の柱や壁などの測定対象の傾きを測定する傾き測定器であって、測定対象に当接する長尺の角柱形状の柱体と、レーザ光を発生させるレーザ発振器と、柱体の長手方向の一端部から柱体の一側面に直交する方向へ突設され、常に鉛直下方向にレーザ光が照射されるようにレーザ発振器をジンバル構造により前後左右に揺動自在に支持する支持体と、柱体の他端部から支持体と同じ方向へ突設され、レーザ発振器のレーザ光による光点が形成される標的体とを備え、標的体には、柱体の長手方向が鉛直方向であった場合にレーザ発振器のレーザ光による光点が形成される目盛が、柱体に対する標的体の突出方向に沿って設けられていることを特徴とする。 The invention of claim 1 is an inclination measuring device for measuring the inclination of a measuring object such as a pillar or wall of a building, and is a long prismatic columnar body that abuts on the measuring object, and a laser that generates laser light. Oscillator, and projecting in a direction perpendicular to one side of the column from one end in the longitudinal direction of the column , the laser oscillator is swung back and forth and left and right by a gimbal structure so that laser light is always irradiated vertically downward a support for rotatably supported, is projected from the other end of the cylindrical body in the same direction as the support, and a target body point of the laser oscillator by the laser beam is formed, to the target body, columnar body longitudinally scale point of the laser oscillator by the laser beam is formed if it was a vertical direction, characterized that you have provided along the projecting direction of the target body relative to the pillar body.

この発明によれば、下げ振りを用いる場合に比べ、糸と違ってレーザ光には風が当たらないため測定時に風の影響を受けにくいから、測定対象の傾きをより正確に測定することができる。また、レーザ発振器を前後左右に揺動可能としたことにより、標的体の目盛上に光点が位置するように柱体の向きを調整して柱体の長手方向と標的体の突出方向とに直交する方向での柱体の傾きをなくし、柱体の傾きを厳密に標的体の突出方向のみとして測定対象の傾きをより正確に測定することができる。 According to the present invention, unlike the case of using a downward swing, unlike the yarn, the laser beam is not hit by the wind and is not easily affected by the wind at the time of measurement. Therefore, the inclination of the measurement object can be measured more accurately. . In addition, by enabling the laser oscillator to swing back and forth and right and left, the orientation of the column body is adjusted so that the light spot is located on the scale of the target body, so that the longitudinal direction of the column body and the protruding direction of the target body It is possible to eliminate the inclination of the column in the orthogonal direction, and to measure the inclination of the measurement object more accurately with the inclination of the column strictly as the only projecting direction of the target.

請求項２の発明は、請求項１の発明において、レーザ発振器に当接して柱体に対するレーザ発振器の揺動を禁止する禁止位置と、レーザ発振器を揺動可能とする退避位置との間で支持体に対して変位自在なストッパを備えることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, a support is provided between a prohibition position that abuts the laser oscillator and prohibits the oscillation of the laser oscillator relative to the column, and a retreat position that allows the laser oscillator to swing. A stopper is provided that is displaceable with respect to the body.

この発明によれば、運搬時にはストッパを禁止位置に変位させてレーザ発振器の揺動を禁止することができるから、運搬中にレーザ発振器が破損しにくい。   According to the present invention, since the stopper can be displaced to the prohibited position during transportation to prohibit the oscillation of the laser oscillator, the laser oscillator is hardly damaged during transportation.

請求項３の発明は、請求項１又は請求項２の発明において、柱体の一端部に枢設された測定体と、測定体と柱体とがなす角を表示する表示手段とを備えることを特徴とする。   The invention of claim 3 comprises the measuring body pivoted at one end of the column body in the invention of claim 1 or 2, and a display means for displaying an angle formed by the measurement body and the column body. It is characterized by.

この発明によれば、柱体を例えば柱の側面と鴨居の下面のような２個の被測定面の一方に当接させつつ測定体を他方の被測定面に当接させ、柱体と被測定面とがなす角を２個の被測定面がなす角に合わせた状態で表示手段を確認することにより、２個の被測定面がなす角を測定することができる。   According to this invention, for example, the measurement body is brought into contact with the other measured surface while the column body is brought into contact with one of the two measured surfaces such as the side surface of the column and the lower surface of the head, so The angle formed by the two measured surfaces can be measured by checking the display means in a state where the angle formed by the measured surface is matched with the angle formed by the two measured surfaces.

本発明によれば、常に鉛直下向きにレーザ光を放射するように揺動自在に支持されたレーザ発振器を用いることにより、下げ振りを用いる場合に比べ、糸と違ってレーザ光には風が当たらないため、測定時に風の影響を受けにくいから、測定対象の傾きをより正確に測定することができる。また、レーザ発振器を前後左右に揺動可能としたことにより、標的体の目盛上に光点が位置するように柱体の向きを調整して柱体の長手方向と標的体の突出方向とに直交する方向での柱体の傾きをなくし、柱体の傾きを厳密に標的体の突出方向のみとして測定対象の傾きをより正確に測定することができる。 According to the present invention, by using a laser oscillator that is swingably supported so as to always emit laser light vertically downward, unlike the case of using a downward swing, the laser light is exposed to wind. Therefore, the inclination of the measurement object can be measured more accurately because it is not easily affected by wind during measurement. In addition, by enabling the laser oscillator to swing back and forth and right and left, the orientation of the column body is adjusted so that the light spot is located on the scale of the target body, so that the longitudinal direction of the column body and the protruding direction of the target body It is possible to eliminate the inclination of the column in the orthogonal direction, and to measure the inclination of the measurement object more accurately with the inclination of the column strictly as the only projecting direction of the target.

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

本実施形態は、図１に示すように、レーザ光を発生させるレーザ発振器１と、長尺の角柱形状の柱部２１、柱部２１の長手方向の一端部から柱部２１の一側面に直交する方向（図１の右方向）へ突設されレーザ光が１点鎖線Ｒで示すように常に鉛直下向きに照射されるようにレーザ発振器２を揺動自在に支持する支持部２２、及び柱部２１の他端部から支持部２２と同じ方向へ突設されレーザ発振器１のレーザ光が照射される標的部２３を有する測定器本体２とを備える。また、柱部２１には気泡水準器２４が内蔵されている。以下、上下方向は図１を基準とし、図１の左下―右上方向を左右方向と呼び、図１の右下―左上方向を前後方向と呼ぶ。 This embodiment, as shown in FIG. 1 orthogonal, and the laser oscillator 1 for generating a laser beam, the column portion 21 of the prismatic elongated from one longitudinal end portion of the pillar portion 21 on one side of the pillar portion 21 And a column portion that protrudes in the direction (right direction in FIG. 1) and supports the laser oscillator 2 so as to be swingable so that the laser beam is always irradiated vertically downward as indicated by a one-dot chain line R. The measuring device main body 2 having a target portion 23 projecting in the same direction as the support portion 22 from the other end portion 21 and irradiated with the laser light of the laser oscillator 1 is provided. In addition, a bubble level 24 is built in the column portion 21. Hereinafter, the vertical direction is based on FIG. 1, and the lower left-upper right direction in FIG. 1 is referred to as the left-right direction, and the lower right-upper left direction in FIG.

測定器本体２は、例えば、柱部２１となるステンレス製の角筒形状の部品に、支持部２２なる部品と、標的部２３となる部品とが、それぞれねじ止めによって取り付けられてなる。   For example, the measuring instrument main body 2 is formed by attaching a component serving as a support portion 22 and a component serving as a target portion 23 to a stainless steel square tube-shaped component serving as a column portion 21 by screwing.

レーザ発振器１としては、例えばレーザポインタとしても使用される半導体レーザ発振器を用いることができる。   As the laser oscillator 1, for example, a semiconductor laser oscillator that is also used as a laser pointer can be used.

支持部２２の構造としては、例えば図２に示すように、柱部２１に連結された腕部２２ａと、腕部２２ａに上下に貫設された貫通穴２２ｂ内において腕部２２ａに対して軸方向を前後方向として左右に揺動可能となるように枢支された環形状の外環２２ｃと、回転軸が外環２２ｃの回転軸に直交するように外環２２ｃに枢支されレーザ発振器１を保持する内環２２ｄとを有するいわゆるジンバル構造を採用することができる。外環２２ｃの回転軸と内環２２ｄの回転軸との交点すなわちレーザ発振器１の揺動中心と標的部２３との距離は、例えば１ｍである。   For example, as shown in FIG. 2, the support portion 22 has an arm portion 22 a connected to the column portion 21, and a shaft with respect to the arm portion 22 a in a through hole 22 b that extends vertically through the arm portion 22 a. The ring-shaped outer ring 22c pivotally supported so as to be able to swing left and right with the direction being the front-rear direction, and the laser oscillator 1 pivoted on the outer ring 22c so that the rotation axis is orthogonal to the rotation axis of the outer ring 22c. A so-called gimbal structure having an inner ring 22d for holding can be employed. The intersection between the rotation axis of the outer ring 22c and the rotation axis of the inner ring 22d, that is, the distance between the oscillation center of the laser oscillator 1 and the target portion 23 is, for example, 1 m.

また、標的部２３の上面には、柱部２１に対する標的部２３の突出方向に沿って目盛を付してある。この目盛は、柱部２１の長手方向が鉛直方向であった場合にレーザ発振器１のレーザ光による光点が形成される位置を通るように設けられている。また、目盛付近には、柱部２１の長手方向が鉛直方向であった場合にレーザ発振器１のレーザ光による光点が形成される位置を０として該位置からの距離を示す数字を付してある。   Further, a scale is provided on the upper surface of the target portion 23 along the protruding direction of the target portion 23 with respect to the column portion 21. This scale is provided so as to pass through the position where the light spot by the laser beam of the laser oscillator 1 is formed when the longitudinal direction of the column portion 21 is the vertical direction. In addition, a number indicating the distance from the position where the light spot by the laser beam of the laser oscillator 1 is formed is set to 0 near the scale when the longitudinal direction of the column portion 21 is the vertical direction. is there.

本実施形態を用いて測定対象の傾きを測定するには、レーザ発振器１の電源が入った状態で、測定器本体２を、支持部２２が標的部２３の上側に位置する向きとして、柱部２１において支持部２２及び標的部２３が突出した面の反対面を測定対象に当接させる。すると、標的部２３において、鉛直方向に対する柱部２１の傾きすなわち柱部２１が当接した測定対象の傾きに応じた位置に、レーザ発振器１のレーザ光によって光点が形成される。つまり、光点の位置の目盛を読むことにより、柱部２１が当接した測定対象の傾きを測定することができる。   In order to measure the tilt of the measurement object using the present embodiment, the measuring instrument main body 2 is placed in the orientation in which the support portion 22 is located above the target portion 23 with the power of the laser oscillator 1 turned on. In 21, the opposite surface of the surface from which the support portion 22 and the target portion 23 protrude is brought into contact with the measurement object. Then, in the target portion 23, a light spot is formed by the laser light of the laser oscillator 1 at a position corresponding to the inclination of the column portion 21 with respect to the vertical direction, that is, the inclination of the measurement object with which the column portion 21 abuts. That is, by reading the scale of the position of the light spot, it is possible to measure the inclination of the measurement object with which the column portion 21 abuts.

ここで、柱部２１に対する支持部２２の突出寸法と、柱部２１に対する標的部２３の突出寸法とは略等しくしてある。これにより、例えば突起があって柱部２１を密着させることができない測定対象に対しても、支持部２２の先端と標的部２３の先端とをそれぞれ測定対象に当接させることにより、柱部２１の傾きを測定対象の傾きに合わせることができる。さらに、支持部２２の先端と標的部２３の先端とをそれぞれ床面や鴨居などの水平に近い被測定面に当接させて気泡水準器２４を確認することにより、上記被測定面が水平か否かを知ることができる。   Here, the protrusion dimension of the support part 22 with respect to the pillar part 21 and the protrusion dimension of the target part 23 with respect to the pillar part 21 are substantially equal. Thereby, for example, even with respect to a measurement target that has protrusions and cannot be brought into close contact with the column part 21, the tip of the support part 22 and the tip of the target part 23 are brought into contact with the measurement object, respectively. Can be matched to the inclination of the object to be measured. Further, by checking the bubble level 24 by bringing the tip of the support portion 22 and the tip of the target portion 23 into contact with a nearly horizontal surface to be measured such as a floor surface or a duck, respectively, the surface to be measured is horizontal. You can know whether or not.

上記構成によれば、レーザ発振器１のレーザ光を用いて測定対象の傾きを示すことにより、下げ振りを用いる従来の傾き測定器に比べ、糸と違ってレーザ光には風が当たることがないため風の影響を受けにくいから、測定対象の傾きを正確に測定することができる。   According to the above configuration, the laser light from the laser oscillator 1 is used to indicate the tilt of the object to be measured, so that unlike the conventional tilt measuring device using a downward swing, the laser beam is not exposed to wind. Therefore, since it is hard to be influenced by the wind, the inclination of the measuring object can be measured accurately.

ここで、実際に測定される方向は、柱部２１に対してレーザ発振器１が標的部２３の突出方向に揺動する方向の傾きのみであるが、本実施形態は、レーザ発振器１を前後左右に揺動可能としたことにより、標的部２３の目盛上に光点が位置するように柱部２１の向きを調整して柱部２１の長手方向と標的部２３の突出方向とに直交する方向での柱部２１の傾き（以下、「不要な傾き」という。）をなくし、柱部２１の傾きを厳密に標的部２３の突出方向のみとして測定対象の傾きをより正確に測定することができる。なお、目視のみで不要な傾きを少なくして得られる精度で十分である場合には、柱部２１に対する標的部２３の突出方向にのみレーザ発振器１を揺動可能としてもよく、この場合には、支持部２２の構造を単純化して製造コストを低減することができる。   Here, the direction actually measured is only the inclination in the direction in which the laser oscillator 1 swings in the projecting direction of the target portion 23 with respect to the column portion 21. The direction of the pillar part 21 is adjusted so that the light spot is located on the scale of the target part 23 by making it swingable, and the direction orthogonal to the longitudinal direction of the pillar part 21 and the protruding direction of the target part 23 The inclination of the column part 21 (hereinafter referred to as “unnecessary inclination”) is eliminated, and the inclination of the column part 21 can be strictly measured only in the protruding direction of the target part 23 so that the inclination of the measurement object can be measured more accurately. . If the accuracy obtained by reducing unnecessary inclination by visual observation is sufficient, the laser oscillator 1 may be oscillated only in the protruding direction of the target portion 23 with respect to the column portion 21. In this case, In addition, the structure of the support portion 22 can be simplified and the manufacturing cost can be reduced.

ところで、レーザ発振器１を揺動自在のまま運搬すると、レーザ発振器１が障害物に引っ掛かって破損してしまうことも考えられる。   By the way, if the laser oscillator 1 is transported while being swingable, the laser oscillator 1 may be caught by an obstacle and damaged.

そこで、図３に示すように、運搬時にレーザ発振器１の揺動を禁止するストッパ３を設けてもよい。図３のストッパ３は、測定器本体２の柱部２１に固定される取付金具３１と、取付金具３１に対して軸方向を前後方向として上下に揺動可能に枢支された固定板３２とからなる。   Therefore, as shown in FIG. 3, a stopper 3 that prohibits the oscillation of the laser oscillator 1 during transportation may be provided. The stopper 3 in FIG. 3 includes a mounting bracket 31 that is fixed to the column portion 21 of the measuring instrument main body 2, and a fixing plate 32 that is pivotally supported with respect to the mounting bracket 31 so as to swing up and down with the axial direction as the front-rear direction. Consists of.

取付金具３１は、図４に示すように、２個の貫通穴３１ａを有し例えば貫通穴３１ａに挿通されるブラインドリベットによって柱部２１に固定される本体部３１ｂと、本体部３１ｂの両端部から互いに同じ方向へ突設された腕部３１ｃとを有してコ字形状に形成されている。各腕部３１ｃには、それぞれ軸体３３が挿通される軸挿通穴３１ｄが貫設されている。 As shown in FIG. 4, the mounting bracket 31 has two through holes 31a, for example, a main body portion 31b fixed to the column portion 21 by blind rivets inserted through the through holes 31a, and both end portions of the main body portion 31b. And an arm portion 31c projecting in the same direction from each other. Each arm portion 31c is provided with a shaft insertion hole 31d through which the shaft body 33 is inserted.

固定板３２には、図５に示すように、軸体３３が挿通される軸挿通穴３２ａが幅方向に貫設され、レーザ発振器１の下端部が収納・保持される保持穴３２ｂが厚さ方向に貫設されている。固定板３２は、取付金具３１の軸挿通穴３１ｄと固定板３２の軸挿通穴３２ａとに挿通された軸体３３により枢支されている。これにより、固定板３２は、レーザ発振器１の下端部を保持穴３２ｂに収納して柱部２１に対するレーザ発振器１の揺動を禁止する禁止位置よりも僅かに下方へ回動した位置と、禁止位置から上方へ回動して測定時のレーザ発振器１の動作に干渉しない退避位置との間で変位自在となっている。 As shown in FIG. 5, the fixing plate 32 has a shaft insertion hole 32a through which the shaft body 33 is inserted in the width direction, and a holding hole 32b in which the lower end portion of the laser oscillator 1 is stored and held is thick. It is penetrated in the direction. The fixed plate 32 is pivotally supported by a shaft body 33 inserted through the shaft insertion hole 31 d of the mounting bracket 31 and the shaft insertion hole 32 a of the fixed plate 32. As a result, the fixed plate 32 is placed in a position where the lower end portion of the laser oscillator 1 is housed in the holding hole 32b and slightly rotated below the prohibition position where the oscillation of the laser oscillator 1 with respect to the column portion 21 is prohibited. It is freely displaceable from a retracted position that rotates upward from the position and does not interfere with the operation of the laser oscillator 1 during measurement.

さらに、測定器本体２の柱部２１と固定板３２とに当接し、固定板３２を退避位置へ向けて付勢する線ばねからなる復帰ばね３４を設けている。   Further, a return spring 34 is provided which is a wire spring that abuts against the column portion 21 of the measuring instrument body 2 and the fixed plate 32 and biases the fixed plate 32 toward the retracted position.

上記ストッパ３の使用方法を説明する。運搬時は、復帰ばね３４のばね力に抗して固定板３２を禁止位置よりも僅かに下げてレーザ発振器１を保持穴３２ｂに導入する。すると、復帰ばね３４のばね力により固定板３２が禁止位置に維持され、レーザ発振器１の揺動が禁止されるから、レーザ発振器１の破損が防止される。ここで、保持穴３２ｂの内面は、禁止位置で上側に位置する開口に近い位置ほど内径を大きくするように傾きしており、これによりレーザー発振器１の下端部を保持穴３２ｂに導入しやすくなっている。また、使用時は、復帰ばね３４のばね力に抗して固定板３２を禁止位置よりも僅かに下げ、レーザ発振器１を保持穴３２ｂから導出して固定板３２の可動範囲から退避させつつ、復帰ばね３４のばね力により固定板３２を退避位置に復帰させる。すると、以後は固定板３２がレーザ発振器１の揺動の邪魔になることがなく、傾きの測定を問題無く行うことができる。   A method of using the stopper 3 will be described. During transportation, the laser oscillator 1 is introduced into the holding hole 32b by slightly lowering the fixing plate 32 from the prohibited position against the spring force of the return spring 34. Then, the fixing plate 32 is maintained at the prohibited position by the spring force of the return spring 34 and the oscillation of the laser oscillator 1 is prohibited, so that the laser oscillator 1 is prevented from being damaged. Here, the inner surface of the holding hole 32b is inclined so as to increase the inner diameter as the position is closer to the opening located at the upper side in the prohibition position, thereby making it easier to introduce the lower end portion of the laser oscillator 1 into the holding hole 32b. ing. In use, the fixing plate 32 is slightly lowered from the prohibited position against the spring force of the return spring 34, and the laser oscillator 1 is led out from the holding hole 32b and retracted from the movable range of the fixing plate 32, The fixing plate 32 is returned to the retracted position by the spring force of the return spring 34. Then, the fixed plate 32 does not interfere with the oscillation of the laser oscillator 1 and the tilt can be measured without any problem.

さらに、例えば発光ダイオードのような光源を有し標的部２３の目盛を照明する照明装置（図示せず）を設けてもよい。このような照明装置や、照明装置の電源となる電池は、例えば測定器本体２の柱部２１に内蔵することができる。この構成を採用すれば、暗所での測定を行いやすくなる。   Furthermore, you may provide the illuminating device (not shown) which has light sources, such as a light emitting diode, and illuminates the scale of the target part 23, for example. Such an illuminating device or a battery serving as a power source for the illuminating device can be incorporated in the column portion 21 of the measuring device main body 2, for example. Employing this configuration facilitates measurement in the dark.

また、目盛に沿って標的部２３に対して左右にスライド自在な指示部（図示せず）を設けてもよい。このような指示部は周知の技術で実現可能であるので、詳細な説明は省略する。この構成を採用すれば、傾きの測定時にレーザ光の光点が形成された位置を示すように指示部をスライドさせることにより、測定した傾きを記憶させることができ、例えば２箇所の傾斜を比較する場合に有用である。   Moreover, you may provide the instruction | indication part (not shown) slidable to the left and right with respect to the target part 23 along a scale. Since such an instruction unit can be realized by a known technique, detailed description thereof is omitted. If this configuration is adopted, the measured tilt can be memorized by sliding the pointing unit to indicate the position where the light spot of the laser beam is formed during tilt measurement. For example, two tilts can be compared. Useful when you want.

さらに、図６に示すように、柱部２１を支持部２２の上方へ延長し、柱部２１の上端部に測定部２５を枢着するとともに、測定部２５が柱部２１に対してなす角を表示する表示部４を設けてもよい。表示部４は、例えば測定部２５の回転中心を中心とする円弧形状の貫通穴４１ａを有し測定部２５に固定された表示板４１と、貫通穴４１ａを貫通し柱部２１に螺合した表示ねじ４２とから構成することができる。この場合、貫通穴４１ａの幅寸法を表示ねじ４２の頭部の外径よりも小さくすれば、表示ねじ４２を締めつけることにより、柱部２１に対する測定部２５の回動を禁止することができる。貫通穴４１ａには、柱部２１と測定部２５とのなす角と表示ねじ４２の位置との対応関係を示す目盛及び数字（図示せず）が付されている。この構成を採用すれば、柱部２１を例えば柱Ｐの側面や壁面のような第１の被測定面に当接させ、測定部２５を例えば床（図示せず）の上面や鴨居Ｋの下面のような第２の被測定面に当接させて、柱部２１と測定部２５とがなす角を、第１の被測定面と第２の被測定面とがなす角に合わせた状態で、表示板４１において表示ねじ４２に近接する目盛を確認することにより、第１の被測定面と第２の被測定面とがなす角を測定することができる。さらに、図６の例では、標的部２３を柱部２１の下端部に枢着して標的部２３が柱部２１に対してなす角を可変とするとともに、表示部４を標的部２３側にも設け、標的部２３でも角度の測定を可能としている。なお、表示板４１と表示ねじ４２との位置関係を入れ替え、表示板４１を柱部２１（又は標的部２３）に固定するとともに表示ねじ４２を測定部２５（又は柱部２１）に螺合させてもよい。   Furthermore, as shown in FIG. 6, the column portion 21 is extended above the support portion 22, the measurement unit 25 is pivotally attached to the upper end portion of the column portion 21, and the angle formed by the measurement unit 25 with respect to the column portion 21. You may provide the display part 4 which displays. The display unit 4 includes, for example, a display plate 41 having an arc-shaped through hole 41 a centered on the rotation center of the measurement unit 25 and fixed to the measurement unit 25, and is screwed into the column unit 21 through the through hole 41 a. The display screw 42 can be used. In this case, if the width dimension of the through hole 41 a is made smaller than the outer diameter of the head of the display screw 42, the rotation of the measuring unit 25 relative to the column part 21 can be prohibited by tightening the display screw 42. The through hole 41a is provided with a scale and a number (not shown) indicating the correspondence between the angle formed by the column portion 21 and the measurement portion 25 and the position of the display screw 42. If this configuration is adopted, the column portion 21 is brought into contact with a first measured surface such as a side surface or a wall surface of the column P, and the measurement unit 25 is disposed on the floor (not shown) or the lower surface of the Kamoi K, for example. In such a state that the angle formed between the column portion 21 and the measurement unit 25 is matched with the angle formed between the first measurement surface and the second measurement surface. By confirming the scale close to the display screw 42 on the display plate 41, the angle formed by the first measured surface and the second measured surface can be measured. Further, in the example of FIG. 6, the target portion 23 is pivotally attached to the lower end portion of the column portion 21, the angle formed by the target portion 23 with respect to the column portion 21 is variable, and the display unit 4 is placed on the target portion 23 side. Also, the target unit 23 can measure the angle. Note that the positional relationship between the display plate 41 and the display screw 42 is changed, the display plate 41 is fixed to the column portion 21 (or the target portion 23), and the display screw 42 is screwed to the measurement unit 25 (or the column portion 21). May be.

また、表示部４は上記構成に限られず、表示板４１や表示ねじ４２に代えて、他の周知の角度測定器の構造を採用してもよい。   In addition, the display unit 4 is not limited to the above configuration, and instead of the display plate 41 and the display screw 42, another known angle measuring device structure may be employed.
