Description

本発明は、構造体の持つ設置面に垂直に穿設された孔の位置を取得するための２次元座標読み取り装置および方法に関する。 The present invention relates to a two-dimensional coordinate reading device and a method for acquiring the position of a hole bored perpendicularly to an installation surface of a structure.

従来から、コンクリートの壁面（構造体の持つ設置面）に、あと施工によって各種部材を設置する場合、アンカーボルトが用いられている。この設置の際、まずコンクリート壁面にドリル等でアンカー孔を穿孔し、このアンカー孔にアンカーボルトを挿入して、先端の拡張部を開かせる、または接着剤を充填することで固定するようになっている。このアンカー孔が設計通りの位置に穿孔できているかを測定するには、半透明の型板フィルムを基準墨に合わせて固定し、孔位置を透かしてフィルムに転写する方法がとられる。そして、型板フィルムを別途平面に広げ、写し取った孔形状や管形状から、孔中心位置を求め、基準位置からの距離を差金や鋼尺等で計測する方法がとられている。 Conventionally, anchor bolts have been used when various members are installed on a concrete wall surface (installation surface of a structure) by post-construction. At the time of this installation, an anchor hole is first drilled in the concrete wall surface with a drill or the like, and an anchor bolt is inserted into this anchor hole to open the expansion part at the tip or to fix it by filling it with an adhesive. ing. In order to measure whether or not the anchor holes are perforated at the designed positions, a method is adopted in which a translucent template film is fixed according to the reference ink, and the holes are transparently transferred to the film. Then, a method is adopted in which the template film is separately spread on a flat surface, the hole center position is obtained from the copied hole shape and tube shape, and the distance from the reference position is measured by a difference or a steel scale.

一方、型紙フィルムを用いずに、直接レーザートラッカーやアーム型三次元測定装置を用いて座標を取得する方法もある。たとえば、特許文献１には、ワークを測定するプローブと、先端に該プローブを備える多関節アーム機構と、を有する多関節型三次元測定装置が開示されている。 On the other hand, there is also a method of directly acquiring coordinates by using a laser tracker or an arm-type coordinate measuring device without using a paper pattern film. For example, Patent Document 1 discloses an articulated three-dimensional measuring apparatus having a probe for measuring a work and an articulated arm mechanism provided with the probe at the tip.

さらに、特許文献２や非特許文献１では、デジタルカメラを複数台用意し、または、複数枚の画像を撮影し、画像解析して、３次元の座標モデルを作成する技術が開示されている。 Further, Patent Document 2 and Non-Patent Document 1 disclose a technique of preparing a plurality of digital cameras, or taking a plurality of images, analyzing the images, and creating a three-dimensional coordinate model.

しかしながら、指金や鋼尺等で計測する方法では、正確で、確認が容易である利点を有するものの、手作業のため、データの転記に手間がかかるうえ、誤記や判読不能で再度計測するなどの問題が生じている。 However, although the method of measuring with a steel square or a steel square has the advantage of being accurate and easy to confirm, it takes time to transfer the data due to manual work, and it is measured again due to erroneous writing or unreadable. Problem is occurring.

図１は、本発明の一実施形態にかかる２次元座標読み取り装置１００を示す概略図である。構造体の持つ設置面に載置または固定される本体を兼ねた台座１と、台座１中央上部に設置され、一端を台座１に垂直な軸を中心に回転可能に軸支された第１の腕部２と、第１の腕部の他端に一端が回転可能に軸支された第２の腕部３を有している。第２の腕部３の他端には、孔位置取得機構としての光学センサ５が設置されている。なお、本実施形態では、腕部２、３は、棒状体であり、第１の腕部２と第２の腕部３は、略等長となっている。 FIG. 1 is a schematic view showing a two-dimensional coordinate reading device 100 according to an embodiment of the present invention. A pedestal 1 that also serves as a main body to be mounted or fixed on the installation surface of the structure, and a first pedestal that is installed at the upper center of the pedestal 1 and has one end rotatably supported around an axis perpendicular to the pedestal 1. It has an arm portion 2 and a second arm portion 3 having one end rotatably supported at the other end of the first arm portion. An optical sensor 5 as a hole position acquisition mechanism is installed at the other end of the second arm portion 3. In the present embodiment, the arm portions 2 and 3 are rod-shaped bodies, and the first arm portion 2 and the second arm portion 3 have substantially the same length.

本実施形態では、台座１の上面に水準器を備えており、構造体の持つ水平な設置面に台座１が載置または固定された場合に、その設置面に対して装置を平行に保つことができる。なお、構造体の持つ設置面が水平でない場合は、装置の台座１の上面を設置面に対し相対的に平行にして使用するものとする。 In the present embodiment, a spirit level is provided on the upper surface of the pedestal 1, and when the pedestal 1 is placed or fixed on the horizontal installation surface of the structure, the device is kept parallel to the installation surface. Can be done. If the installation surface of the structure is not horizontal, the upper surface of the pedestal 1 of the device shall be used relatively parallel to the installation surface.

本実施形態では、台座１に軸支する第１の腕部２の回転軸および第１の腕部２と第２の腕部３を軸支する回転軸は、構造体の持つ設置面に垂直になるように構成されており、このことで、両腕部は、構造体の持つ設置面に平行な面内に規制されて移動可能になっている。また、それぞれの軸部には、角度センサ４が配置されており、測定した角度を、台座１中に収容したコンピュータに伝送している。 In the present embodiment, the rotation axis of the first arm portion 2 that pivotally supports the pedestal 1 and the rotation axis that pivotally supports the first arm portion 2 and the second arm portion 3 are perpendicular to the installation surface of the structure. As a result, both arms are restricted and movable in a plane parallel to the installation surface of the structure. Further, an angle sensor 4 is arranged on each shaft portion, and the measured angle is transmitted to a computer housed in the pedestal 1.

図２に本実施形態での座標取得の一例を示す。図２では、台座１に設けられた第１の腕部２の回転軸を原点Ｏとし、構造体の持つ設置面に平行な、互いに直交する座標軸（ｘ軸およびｙ軸）を定める。第１の腕部２の両端に配置された角度センサにより、ｘ軸と第１の腕部２のなす角θ１および第１の腕部２と第２の腕部３のなす角θ２を計測する。事前に把握した第１の腕部２の長さＬ１および第２の腕部３の長さＬ２を用い、孔位置取得機構５の座標（ｘ、ｙ）は、下記式（１）で求められる。
ｘ＝Ｌ１ｃｏｓ（θ１）＋Ｌ２ｃｏｓ（θ１＋θ２）
ｙ＝Ｌ１ｓｉｎ（θ１）＋Ｌ２ｓｉｎ（θ１＋θ２） ・・・（１） FIG. 2 shows an example of coordinate acquisition in this embodiment. In FIG. 2, the rotation axis of the first arm portion 2 provided on the pedestal 1 is set as the origin O, and coordinate axes (x-axis and y-axis) parallel to the installation surface of the structure and orthogonal to each other are defined. Angle sensors arranged at both ends of the first arm 2 determine the angle θ 1 formed by the x-axis and the first arm 2 and the angle θ 2 formed by the first arm 2 and the second arm 3. measure. Using the length L 1 of the first arm portion 2 and the length L 2 of the second arm portion 3 grasped in advance, the coordinates (x, y) of the hole position acquisition mechanism 5 are expressed by the following equation (1). Desired.
x = L 1 cos (θ 1 ) + L 2 cos (θ 1 + θ 2 )
y = L 1 sin (θ 1 ) + L 2 sin (θ 1 + θ 2 ) ・ ・ ・ (1)

上記座標の計算は、角度センサ４の情報を取得する台座（本体）１に収容したマイコンで行ってもよいし、外部のコンピュータに伝送して行ってもよい。計算された座標は、デジタルの数値として、座標表示部７として台座（本体）１に組み込んだ表示器や、別途用意した操作端末９などの外部表示器に表示させてもよい。 The calculation of the coordinates may be performed by a microcomputer housed in the pedestal (main body) 1 for acquiring the information of the angle sensor 4, or may be transmitted to an external computer. The calculated coordinates may be displayed as digital numerical values on a display incorporated in the pedestal (main body) 1 as the coordinate display unit 7 or an external display such as a separately prepared operation terminal 9.

本実施形態では、２軸として回転軸を用いたが、平行でない並進軸を２軸以上組み合わせたり、回転軸と並進軸を組みあわせたりして、構造体の持つ設置面に平行な平面内で移動可能に構成できれば、その組み合わせは自由である。また、取得情報として、並進軸の場合には、移動距離を計測することが好ましい。 In this embodiment, the rotation axis is used as the two axes, but by combining two or more non-parallel translational axes or by combining the rotation axis and the translational axis, in a plane parallel to the installation surface of the structure. If it can be configured to be movable, the combination is free. Further, as the acquired information, in the case of the translation axis, it is preferable to measure the moving distance.

本実施形態にかかる２次元座標読み取り装置１００の効果を把握するため、マイラ紙に１４点の孔の位置を転写したものを用い、従来通り差金を用いて座標を取得した場合（比較例）と、本実施形態にかかる２次元座標読み取り装置１００を用いて、座標を取得した場合（発明例）の作業時間を比較した。発明例によれば比較例の約１／４の時間で座標を取得でき、作業の効率化が図れている。加えて、比較例では、デジタル化の際に誤記の修正が生じたが、発明例では座標のデジタルデータを直接取得するため、原理上誤記が生じない利点がある。 In order to understand the effect of the two-dimensional coordinate reading device 100 according to the present embodiment, a case where the coordinates are obtained by transferring the positions of 14 holes on Myra paper and using the difference as before (comparative example). Using the two-dimensional coordinate reading device 100 according to the present embodiment, the working hours when the coordinates were acquired (example of the invention) were compared. According to the invention example, the coordinates can be acquired in about 1/4 of the time of the comparative example, and the work efficiency is improved. In addition, in the comparative example, the typographical error was corrected during digitization, but in the invention example, since the digital data of the coordinates is directly acquired, there is an advantage that the typographical error does not occur in principle.

図３には、本発明の他の実施形態として、孔位置取得機構として針状部材６を設けた例を示す。この針状部材６の先端を孔位置に合わせて、座標を読み取ることができる。また、針状部材６に代えて、円錐状部材等の孔位置を指示できる形状が適用可能である。孔位置取得機構として、腕部の端部から設置面に対し垂直な光軸を有するレーザーポインターを設置してもよい。 FIG. 3 shows an example in which a needle-shaped member 6 is provided as a hole position acquisition mechanism as another embodiment of the present invention. The coordinates can be read by aligning the tip of the needle-shaped member 6 with the hole position. Further, instead of the needle-shaped member 6, a shape capable of instructing the hole position of the conical member or the like can be applied. As the hole position acquisition mechanism, a laser pointer having an optical axis perpendicular to the installation surface from the end of the arm may be installed.

次に上記実施形態の２次元座標読み取り装置１００を用いた２次元座標読み取り方法について説明する。図４は、孔中心軸に沿ってレーザー光Ｌを照射する芯出し装置１０を用いて、孔の位置座標を取得する概略図である。 Next, a two-dimensional coordinate reading method using the two-dimensional coordinate reading device 100 of the above embodiment will be described. FIG. 4 is a schematic diagram for acquiring the position coordinates of the hole by using the centering device 10 that irradiates the laser beam L along the central axis of the hole.

この２次元座標読み取り方法では、構造体の持つ設置面に垂直に穿設された孔の位置を取得するために、まず、芯出し装置１０を孔内に挿入して、孔の外部に向かって中心位置表示光、つまり、孔の中心軸に一致させたレーザー光Ｌを孔の外部に向かって照射させる（芯出しステップ）。 In this two-dimensional coordinate reading method, in order to acquire the position of the hole drilled perpendicularly to the installation surface of the structure, first, the centering device 10 is inserted into the hole and toward the outside of the hole. The center position display light, that is, the laser beam L aligned with the central axis of the hole is irradiated toward the outside of the hole (centering step).

次に、２次元座標読み取り装置１００を構造体の持つ設置面に台座１の上面が平行になるように載置または固定する（設置ステップ）。第２の腕部３の先端に設置した孔位置取得機構としての光学センサ５を原点および基準となる座標軸に合わせて座標の基準を取得する（基準ステップ）。そして、芯出し装置１０が照射するレーザー光Ｌを光学センサ５で検出して、孔中心座標を取得する（座標取得ステップ）。その後は２次元座標読み取り装置１００の座標表示部７から座標の数値を読み取り、場合によっては、コンピュータに記憶させる（座標表示ステップ）。これにより、現場で簡便に精確に孔の中心位置座標を取得することができる。 Next, the two-dimensional coordinate reading device 100 is placed or fixed so that the upper surface of the pedestal 1 is parallel to the installation surface of the structure (installation step). An optical sensor 5 as a hole position acquisition mechanism installed at the tip of the second arm 3 is aligned with the origin and a reference coordinate axis to acquire a coordinate reference (reference step). Then, the laser beam L irradiated by the centering device 10 is detected by the optical sensor 5 to acquire the hole center coordinates (coordinate acquisition step). After that, the numerical value of the coordinates is read from the coordinate display unit 7 of the two-dimensional coordinate reading device 100, and in some cases, it is stored in the computer (coordinate display step). This makes it possible to easily and accurately acquire the center position coordinates of the hole at the site.

なお、上記例の光学センサ５に代えて、孔位置取得機構に針状体６や円錐状体またはレーザーポインターを用いた場合には、上記座標取得ステップにおいて、孔位置取得機構が所定位置を指示したときに、装置本体１に設置した座標取得ボタン８を押すこと、または、別途用意したスマートフォンなどの操作端末９を操作することにより、座標を取得するようにしてもよい。操作端末９には、表示画面上に取得座標の表示や座標取得のためのボタン操作を可能とするアプリケーションソフトウェアをインストールすることが好ましい。 When a needle-shaped body 6, a conical body, or a laser pointer is used for the hole position acquisition mechanism instead of the optical sensor 5 of the above example, the hole position acquisition mechanism indicates a predetermined position in the coordinate acquisition step. At that time, the coordinates may be acquired by pressing the coordinate acquisition button 8 installed on the device main body 1 or by operating an operation terminal 9 such as a smartphone prepared separately. It is preferable to install application software on the operation terminal 9 that enables the display of the acquired coordinates and the button operation for the coordinate acquisition.

上記例では、現場でそのまま孔中心座標を取得する例を示したが、構造体の持つ設置面が、曲面や傾斜している場合には、事前に半透明の薄膜に孔の中心位置を転写しておき、水平な面に展開して、本発明にかかる２次元座標読み取り装置により、転写した孔の中心位置座標を読み取るようにしてもよい。 In the above example, the hole center coordinates are acquired as they are at the site, but if the installation surface of the structure is curved or inclined, the hole center position is transferred to the translucent thin film in advance. However, it may be developed on a horizontal surface and the center position coordinates of the transferred hole may be read by the two-dimensional coordinate reading device according to the present invention.
