Abstract

<P>PROBLEM TO BE SOLVED: To provide an expansion/contraction length indication type surveying level rod capable of showing automatically by a simple structure, a height of the surveying level rod which is changed by being slidingly-expanded/contracted. <P>SOLUTION: A slide part constituting a surveying level rod lower part 15 is slid with respect to a slide guide part constituting a surveying level rod upper part 13, to thereby expand/contract the whole surveying level rod 3. Sliding of the surveying level rod lower part 15 is performed on the back side of the surface 19 of the surveying level rod upper part. Hereby, the upper side of a total scale 17 is hidden from the surface 19 of the surveying level rod upper part by sliding, and a residual lower side is exposed. The total scale 17 has a total dimension value determined by totalizing a dimension of the surveying level rod upper part 13 to a dimension from the lower end 21 of the surveying level rod lower part 15. Consequently, a numerical value of an upper end exposed to the surface side indicates a dimension of the whole surveying level rod 3 which is changed by being expanded/contracted. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

この発明は、例えば床の凹凸を測定するための測量用標尺の構造に関する。   The present invention relates to a structure of a surveying staff for measuring unevenness of a floor, for example.

例えば、建築中や増改築中の建物で、コンクリートを流し込んで形成するコンクリート床の凹凸を正確に測定する必要がある。
この測定は、例えば、以下のように行う。すなわち、一人の作業員が、床の上に測量用標尺を下端を接して垂直に支持する。他の作業員は、測量用標尺から離れた基準床面の上で測量機器であるレベルを設置する。この測量機器であるレベルは、基準床面の一定寸法上方、例えば150cm方において、水平に設置され、内蔵する光学機器で、この水平な位置にあるものを、拡大して目視できる。この測量機器であるレベルによって、測量用標尺の下端から一定寸法上方に設けられる目標目盛を狙う。
For example, it is necessary to accurately measure the unevenness of a concrete floor formed by pouring concrete in a building under construction or expansion / renovation.
This measurement is performed as follows, for example. That is, one worker supports the surveying staff on the floor vertically with the lower end in contact. Other workers install a level which is a surveying instrument on a reference floor surface away from the surveying ruler. The level of the surveying instrument is set horizontally above a reference floor surface, for example, about 150 cm, and is a built-in optical instrument that can be viewed in an enlarged manner at the horizontal position. A target scale provided above a certain distance from the lower end of the surveying scale is aimed at by the level as the surveying instrument.

コンクリート床に凹凸があり、測量用標尺を支持した部分が、凹の部分であれば、測量用標尺は沈むので、狙いは上にずれる。逆に、凸の部分であれば、下にずれる。このずれの大きさを、測量機器であるレベルを通し拡大した目標目盛で読み取ることで、凹凸の大きさを測定する。このような測定を床の上の各所で行い、床全体の凹凸を測定する。   If the concrete floor has irregularities and the part that supports the surveying standard is a concave part, the surveying standard will sink and the aim will be shifted upward. On the contrary, if it is a convex part, it will shift down. The size of the unevenness is measured by reading the magnitude of this deviation with a target scale enlarged through the level of the surveying instrument. Such measurement is performed at various points on the floor, and the unevenness of the entire floor is measured.

このような床の凹凸の測定は、他にも測定方法がある。たとえば、レーザー光を用いた測定である。すなわち、レーザー水平器と呼ばれる測定器を用い、レーザー水平器を気泡管によって、水平に設置し、この水平面に対して平行なレーザー光線を照射し、この照射光の反射を、測量用標尺の目標目盛の上で、目視で確認し、凹凸の大きさを測定する。   There are other measurement methods for measuring the unevenness of the floor. For example, measurement using laser light. That is, using a measuring instrument called a laser leveling device, the laser leveling device is installed horizontally by a bubble tube, irradiated with a laser beam parallel to the horizontal plane, and the reflected light is reflected on the target scale of the measuring scale. On the top, check visually and measure the size of the irregularities.

このレーザー光を用いた測定で用いられる測量用標尺には、下記の特許文献1に示され、上下方向にスライドして伸縮するものが存在する。
米国特許006760974
As a surveying standard used in the measurement using the laser beam, there is one that is shown in the following Patent Document 1 and slides in the vertical direction to expand and contract.
US Patent 006760974

測量用標尺を上下方向にスライドして伸縮する構造にすれば、レーザー水平器の床面からの高さを正確に設定しなくても、測量用標尺の目標目盛の高さを伸縮により変更できるので、レーザー水平器の高さに自在に合わせられ、作業が便利である。レーザー水平器は三脚によって設置され、三脚により高さを正確に設置するのは難しいからである。   If the measuring scale is slid up and down to expand and contract, the target scale height of the measuring scale can be changed by expansion and contraction without setting the height of the laser level from the floor accurately. Therefore, it can be freely adjusted to the height of the laser level and work is convenient. This is because the laser level is installed on a tripod, and it is difficult to set the height accurately using the tripod.

この便利さは、例えば、レーザー水平器を設置する設置面をどこに選択するかによって設置面の高さが変わるとき、作業者の背の高さや好みによって作業しやすいレーザー水平器の高さが変わるとき、などに特に便利である。
以上のことは、レーザー水平器を使用する測定だけではなく、測量機器のレベルを使用する測定においても同様のことが言える。
For example, when the height of the installation surface changes depending on where the installation surface on which the laser level is installed is selected, the height of the laser level that is easy to work changes depending on the height and preference of the operator. Especially useful when, etc.
The same can be said for the measurement using the level of the surveying instrument as well as the measurement using the laser level.

しかしながら、レーザー水平器や測量機器のレベルが設置された高さの平面、すなわち水平基準面が、設計上の床面から、どれだけの高さであったかを作業中に測定しておく必要がある。
すなわち、建築中の建物のn階には、基準となる階水平基準面の高さを示す印Hnが、足場などに印付けられる。この印Hnは、各階の設計上の床から例えば一律1000mmに設定される。そして、各階の作業のための水平基準面は、作業員の背の高さや、測量機器のレベルの操作しやすい高さから、階水平基準面とは別に、任意の高さに設定される。例えば設計上の床から1480mmに設定される。この任意に設定される水平基準面の高さと階水平基準面の高さの対応は、正確に把握されなければならない。
この作業のための水平基準面は、例えばベランダ、開放廊下、玄関、水回り、子供部屋、リビング、それぞれの床に、5cm〜20cmの段差がある場合、その必要に応じて、各々別に設定される。例えばベランダは設計上の床から1480mm、開放廊下は設計上の床から1430mm、玄関は設計上の床から1470mm、水回りは設計上の床から1420mm、子供部屋は設計上の床から1490mm、リビングは設計上の床から1460mm、といった具合であることがある。その場合に伸縮して変化した測量用標尺の高さをそのたびに計測するのは煩わしい。
However, it is necessary to measure during the work how much the level plane on which the level of the laser leveler and surveying instrument is installed, that is, the level of the horizontal reference plane from the design floor surface. .
That is, on the nth floor of the building under construction, a mark Hn indicating the height of the reference floor horizontal reference plane is marked on a scaffold or the like. The mark Hn is set to, for example, uniformly 1000 mm from the design floor of each floor. The horizontal reference plane for work on each floor is set to an arbitrary height separately from the floor horizontal reference plane because of the height of the worker's back and the height at which the level of the surveying instrument is easy to operate. For example, it is set to 1480 mm from the designed floor. The correspondence between the arbitrarily set height of the horizontal reference plane and the height of the floor horizontal reference plane must be accurately grasped.
The horizontal reference plane for this work is set separately according to the necessity, for example, when there is a step of 5 cm to 20 cm on the veranda, open corridor, entrance, water circumference, children's room, living room, and each floor. The For example, the veranda is 1480mm from the design floor, the open corridor is 1430mm from the design floor, the entrance is 1470mm from the design floor, the water is 1420mm from the design floor, the children's room is 1490mm from the design floor, the living room May be 1460 mm from the design floor. In such a case, it is troublesome to measure the height of the surveying measure that has changed due to expansion and contraction.

この発明は、以上の問題点を解決するために、伸縮して変化した測量用標尺の高さが自動的に、簡易な構造により示される伸縮長表示式測量用標尺を提供することを目的とする。   In order to solve the above problems, an object of the present invention is to provide an extendable length display type measuring measure in which the height of a measuring measure that has been expanded and contracted is automatically indicated by a simple structure. To do.

以上の課題を解決するために、第一発明は、測量用標尺の上部を構成し、目標目盛が表面に設けられるスライドガイド部と、このスライドガイド部にガイドされ、前記測量用標尺の下部を構成し、スライドガイド部の表面の背側でスライド移動するスライド部と、前記測量用標尺下部の表面に設けられ、前記測量用標尺下部の下端からの寸法に前記測量用標尺上部の寸法を合計した合計寸法値を有する合計目盛と、を有し、前記スライドにともない伸縮して変化する前記測量用標尺全体の寸法を、前記合計目盛の表面側へ露出する上縁部の数値で表示することを特徴とする伸縮長表示式測量用標尺である。   In order to solve the above problems, the first invention comprises an upper part of a surveying standard, a slide guide part provided with a target scale on the surface, guided by the slide guide part, and a lower part of the measurement standard. The slide part that is configured to slide on the back side of the surface of the slide guide part and the surface of the lower part of the surveying standard, and the dimension from the lower end of the lower part of the measurement standard is the sum of the dimensions of the upper part of the measurement standard A total scale having a total dimension value, and displaying the overall dimension of the surveying scale that expands and contracts with the slide as a numerical value of the upper edge exposed to the surface side of the total scale. This is a telescopic measurement display measuring scale characterized by the following.

第二発明は、床の凹凸を測定するため、床の上に測量用標尺を下端を接して垂直に支持し、この測量用標尺の下端から一定寸法上方に設けられる目標目盛を、前記測量用標尺から離れた基準床面の上で前記一定寸法上方において水平に設置された測量機器のレベルで狙い、狙いのずれの大きさを前記目標目盛で読み取ることで前記凹凸の大きさを測定する前記測量用標尺であって、
前記測量用標尺の上部を構成し、前記目標目盛が表面に設けられるスライドガイド部と、このスライドガイド部にガイドされ、前記測量用標尺の下部を構成し、スライドガイド部の表面の背側でスライド移動するスライド部と、前記測量用標尺下部の表面に設けられ、前記測量用標尺下部の下端からの寸法に前記測量用標尺上部の寸法を合計した合計寸法値を有する合計目盛と、を有し、前記スライドにともない伸縮して変化する前記測量用標尺全体の寸法を、前記合計目盛の表面側へ露出する上縁部の数値で表示することを特徴とする伸縮長表示式測量用標尺である。
In the second invention, in order to measure the unevenness of the floor, the measurement scale is supported on the floor vertically by contacting the lower end, and a target scale provided above the measurement scale by a certain dimension is used for the measurement. Aiming at the level of the surveying instrument installed horizontally above the fixed dimension on the reference floor surface away from the measuring scale, and measuring the size of the irregularities by reading the magnitude of the deviation of the aim with the target scale Surveying measure,
The upper part of the surveying measure is constituted, and the target scale is provided on the surface with a slide guide part, and the slide guide part is guided to constitute the lower part of the surveying measure, and on the back side of the surface of the slide guide part A sliding portion that slides, and a total scale that is provided on the surface of the lower part of the surveying standard and has a total dimension value that is a sum of the dimensions of the upper part of the surveying standard and the dimension from the lower end of the lower part of the surveying standard. The length of the surveying measuring scale that changes due to expansion and contraction with the slide is displayed with the numerical value of the upper edge exposed on the surface side of the total scale. is there.

第一、又は第二発明によれば、測量用標尺上部を構成するスライドガイド部に対し、測量用標尺下部を構成するスライド部を、スライドさせ、測量用標尺全体を伸縮させることができる。この測量用標尺下部のスライドは、測量用標尺上部の表面の背側で行われる。このため、合計目盛の上側は、スライドにより、測量用標尺上部の表面から隠れ、残りの下側は露出する。この合計目盛は、測量用標尺下部の下端からの寸法に測量用標尺上部の寸法を合計した合計寸法値を有するものであるから、表面側へ露出する上縁部の数値は、伸縮して変化する測量用標尺全体の寸法を表示することになる。よって、伸縮して変化した測量用標尺の高さが自動的に、簡易な構造により示される。   According to the 1st or 2nd invention, the slide part which comprises the lower part of the surveying standard can be slid with respect to the slide guide part which comprises the upper part of the measurement standard, and the whole measurement standard can be expanded and contracted. The slide of the lower part of the surveying measure is performed on the back side of the surface of the upper part of the surveying measure. For this reason, the upper side of the total scale is hidden by the slide from the surface of the upper part of the surveying ruler, and the remaining lower side is exposed. This total scale has a total dimension value that is the sum of the dimensions of the upper part of the surveying standard to the dimension from the lower end of the lower part of the standard for surveying. Therefore, the numerical value of the upper edge exposed on the surface side changes with expansion and contraction. The overall dimensions of the surveying staff will be displayed. Therefore, the height of the surveying standard changed by expansion and contraction is automatically indicated by a simple structure.

この発明の実施形態を、図1及び図2に示す。
[測定作業の全体概要]
図2(A)(B)に示すように、この実施形態は、コンクリート床の凹凸を測定するため、この実施形態にかかる測量用標尺3と測量機器のレベル5を用いるものである。
一人の作業員7が、床の上に測量用標尺3を下端を接して垂直に支持する。他の作業員9は、測量用標尺3から離れた基準床面の上で測量機器であるレベル5を設置する。この測量機器であるレベル5は、基準床面の一定寸法上方、例えば150cm上方において、水平に設置される。レベル5に内蔵する光学機器で、この水平な位置にあるものを、拡大して目視できる。
An embodiment of the present invention is shown in FIGS.
[Overview of measurement work]
As shown in FIGS. 2 (A) and 2 (B), this embodiment uses the measuring ruler 3 according to this embodiment and the level 5 of the surveying instrument in order to measure the unevenness of the concrete floor.
One worker 7 vertically supports the surveying measure 3 on the floor with its lower end in contact. The other worker 9 installs level 5 which is a surveying instrument on the reference floor surface away from the surveying measure 3. Level 5 which is this surveying instrument is installed horizontally above a certain dimension above the reference floor, for example, 150 cm above. An optical instrument built in level 5 that is in this horizontal position can be enlarged and viewed.

他の作業員9は、このレベル5をのぞき込んで、測量用標尺3の下端から一定寸法上方に設けられる目標目盛11を狙う。図2(C)に示すように、のぞいた視野には、例えば光学機器のレンズに描き込まれた基準水平線Hが示される。また、のぞいた視野には、光学機器で拡大された目標目盛11がはっきりと目視できる。   The other worker 9 looks into this level 5 and aims at a target scale 11 provided above the lower end of the surveying measure 3 by a certain distance. As shown in FIG. 2C, the peeked visual field shows, for example, a reference horizontal line H drawn on the lens of the optical device. Further, the target scale 11 enlarged by the optical device can be clearly seen in the viewed field.

そして、この目標目盛11には、基準水平目盛Lを境に、上下に、ずれδの大きさを示す目盛りが+−の記号とともに示される。よって、基準水平線Hと基準水平目盛Lを重ねて目視し、両者H,Lのずれδの大きさを、目標目盛11で読み取ることで、コンクリート床の凹凸の大きさを測定することができる。   In the target scale 11, a scale indicating the magnitude of the deviation δ is shown with a +-sign above and below the reference horizontal scale L as a boundary. Therefore, the reference horizontal line H and the reference horizontal scale L are overlapped and visually observed, and the magnitude of the deviation δ between the two H and L is read by the target scale 11, whereby the size of the unevenness of the concrete floor can be measured.

[測量用標尺3]
図1に示すように、この実施形態にかかる測量用標尺3は、スライドして伸縮できるように、測量用標尺上部13と、測量用標尺下部15とからなる。
測量用標尺上部13は、目標目盛11が表面に設けられる。また、全体が細長い四角筒状をなし、スライドガイド部として機能する。
測量用標尺下部15は、測量用標尺上部13の四角筒状に挿入されスライドできる、よりも細い四角柱状をなし、スライド部として機能する。この測量用標尺下部15であるスライド部は、測量用標尺上部13であるスライドガイド部の表面の背側で、スライド移動する。
スライド後の状態を固定するために、固定ネジ16を設ける。すなわち、ハンドのついた雄ネジの先端は、測量用標尺上部13の表面に設けられた雌ネジに螺合して貫通し、貫通したネジの先端が測量用標尺下部15の表面19を押圧して、固定が行われる。
[Surveying measure 3]
As shown in FIG. 1, the surveying measure 3 according to this embodiment includes a surveying measure upper portion 13 and a surveying measure lower portion 15 so that it can slide and expand.
The measurement scale upper part 13 is provided with a target scale 11 on the surface. In addition, the whole has a long and narrow rectangular tube shape and functions as a slide guide portion.
The surveying standard lower part 15 has a smaller rectangular column shape that can be inserted and slid into the rectangular tube shape of the surveying standard upper part 13 and functions as a slide part. The slide portion which is the surveying measure lower portion 15 slides on the back side of the surface of the slide guide portion which is the surveying measure upper portion 13.
In order to fix the state after the slide, a fixing screw 16 is provided. That is, the tip of the male screw with the hand is threaded into and penetrates the female screw provided on the surface of the surveying gauge upper part 13, and the tip of the penetrated screw presses the surface 19 of the surveying gauge lower part 15. Fixing.

また、測量用標尺下部15の表面には合計目盛17が設けられる。この合計目盛17は、測量用標尺下部15の下端からの寸法S1に、測量用標尺上部13の寸法S2を合計した合計寸法値を有する。この測量用標尺上部13の寸法S2とは、測量用標尺上部13の下端から目標目盛11の基準水平目盛Lまでの寸法をいう。   A total scale 17 is provided on the surface of the surveying gauge lower part 15. The total scale 17 has a total dimension value obtained by adding the dimension S2 of the surveying measure upper part 13 to the dimension S1 from the lower end of the surveying measure lower part 15. The dimension S2 of the surveying measure upper part 13 refers to the dimension from the lower end of the surveying measure upper part 13 to the reference horizontal scale L of the target scale 11.

合計目盛17の上側は、スライドにより、測量用標尺上部の表面19から隠れる。残りの下側は露出する。境目は、測量用標尺上部13の下端21である。
これにより、表面側へ露出する上縁部の数値は、伸縮して変化する測量用標尺3全体の寸法を表示することになる。よって、伸縮して変化した測量用標尺3の高さが自動的に、簡易な構造により示される。なお、図3に、測量用標尺をスライドしやや縮めた状態を示す。
The upper side of the total scale 17 is hidden from the surface 19 of the upper part of the surveying gauge by the slide. The remaining underside is exposed. The boundary is the lower end 21 of the upper part 13 for surveying.
Thereby, the numerical value of the upper edge part exposed to the surface side displays the dimension of the whole surveying ruler 3 which expands and contracts. Therefore, the height of the surveying measure 3 that has changed due to expansion and contraction is automatically indicated by a simple structure. FIG. 3 shows a state in which the measuring staff is slid slightly.

「他の実施形態」
以上の実施形態では、測定は測量機器であるレベル5を用いたが、他の実施形態では、レーザー水平器を用いてもよい。目標目盛11へレーザー光線を照射し、この照射光が目標目盛11の上で反射する光る線の部分と、目標目盛11の基準水平目盛とのずれを、目視で確認し、これによりコンクリート凹凸の大きさを測定する。
"Other embodiments"
In the above embodiment, level 5 which is a surveying instrument is used for the measurement, but in another embodiment, a laser level may be used. The target scale 11 is irradiated with a laser beam, and a deviation between the portion of the shining line in which the irradiated light is reflected on the target scale 11 and the reference horizontal scale of the target scale 11 is visually confirmed. Measure the thickness.

以上の実施形態では、測量用標尺上部13の下端21により、合計目盛17の露出する上縁部の数値が指示されるものであったが、他の実施形態では、より明確に指示する工夫を設けてもかまわない。すなわち、例えば、測量用標尺上部13の下端21に、横に細長い指示窓を設け、この指示窓に合計目盛17の露出する上縁部の数値を指示させることも可能である。
以上の実施形態では、測量機器を使用する場合を説明したが、他の実施形態では、レーザー水平器を使用する場合にも、本発明は実施できる。
そのとき、更に、レーザー水平器から水平面に対して平行なレーザー光線を照射するのではなく、垂直面に対して平行なレーザー光線を照射することにより、床の凹凸ではなく、壁面の凹凸の測定にも使用できる。よって、コンクリート壁面の型枠の凹凸を測定し、コンクリート打設前に型枠の精度をあげ、その後にコンクリートを打設する。
つまり、コンクリート壁面の型枠の凹凸を測定するため、壁面の型枠の表面上に測量用標尺を下端を接して水平に支持し、この測量用標尺の下端から一定寸法上方(横方向)に設けられる目標目盛に対して、垂直面に対して平行なレーザー光線を照射する。この照射光の反射を、目標目盛の上で、目視で確認し、凹凸の大きさを測定する。これにより、コンクリート壁面の型枠の凹凸を測定し、コンクリート打設前に型枠の精度をあげ、その後にコンクリートを打設し、精度あるコンクリート壁面を構築できる。
In the above embodiment, the numerical value of the upper edge portion where the total scale 17 is exposed is instructed by the lower end 21 of the surveying measure upper portion 13, but in other embodiments, a device for instructing more clearly is provided. It does not matter if it is provided. That is, for example, it is also possible to provide a horizontally elongated instruction window at the lower end 21 of the surveying gauge upper portion 13 and to indicate the numerical value of the upper edge portion where the total scale 17 is exposed to this instruction window.
In the above embodiment, the case where the surveying instrument is used has been described. However, in another embodiment, the present invention can be implemented even when the laser level is used.
At that time, instead of irradiating a laser beam parallel to the horizontal plane from the laser level, by irradiating a laser beam parallel to the vertical surface, it is also possible to measure the unevenness of the wall, not the unevenness of the floor. Can be used. Therefore, the unevenness of the formwork on the concrete wall surface is measured, the precision of the formwork is increased before placing the concrete, and then the concrete is placed.
In other words, in order to measure the irregularities of the formwork on the concrete wall, the surveying measure is supported horizontally on the surface of the formwork on the wall with the lower end in contact with it, and a certain dimension upward (lateral direction) from the lower end of this surveying measure A laser beam parallel to the vertical plane is applied to the target scale provided. The reflection of the irradiation light is visually confirmed on the target scale, and the size of the unevenness is measured. Thereby, the unevenness | corrugation of the formwork of a concrete wall surface can be measured, the precision of a formwork can be raised before concrete placement, and concrete can be cast after that, and an accurate concrete wall surface can be constructed | assembled.
