Description

本発明は錘下げ振り及び位置合せ方法に関する。   The present invention relates to a weight swinging and alignment method.

従来、例えば特許文献１に記載の如く、２本の水平方向に張られた水糸の交点と、その交点の下方で水平方向に位置合せされた水平位置を定め、当該水平位置に目的物を位置決めして設置するための位置合せ方法がある。   Conventionally, as described in Patent Document 1, for example, an intersection of two horizontally stretched water strings and a horizontal position aligned horizontally below the intersection are determined, and an object is placed at the horizontal position. There are alignment methods for positioning and installation.

特許文献１に記載の位置合せ方法は、例えばベースモルタルの近くに突き立てられる縦長棒体にレーザー照射部を設け、照射部が照射するレーザー光線の垂直光を２本の水糸の交点を経由させてベースモルタル上に到達させ、レーザー光線が指し示すベースモルタル上に印を付ける。   In the alignment method described in Patent Document 1, for example, a laser irradiation unit is provided on a vertically long bar projecting near a base mortar, and the vertical light of the laser beam irradiated by the irradiation unit is passed through the intersection of two water threads. Mark on the base mortar indicated by the laser beam.

尚、レーザー照射部等を用いない簡易な位置合せ方法として、従来方法１〜３（図７〜図９）がある。   In addition, there exist the conventional methods 1-3 (FIGS. 7-9) as a simple alignment method which does not use a laser irradiation part etc. FIG.

従来方法１（図７）は、単純に２本の水糸１、２の交点Ａの鉛直上と思われる視点Ｍから該交点Ａの下方を見下ろし、この視線Ｌが到達した位置に目的物Ｔを設置する。   In the conventional method 1 (FIG. 7), the object T is looked down at the position where the line of sight L has reached from the viewpoint M, which is considered to be vertically above the intersection A of the two water threads 1 and 2. Is installed.

従来方法２（図８）は、２本の水糸１、２の交点Ａに錘下げ振り３の吊り糸３Ａを当て、錘下げ振り３の直下の位置に目的物Ｔを設置する。   In the conventional method 2 (FIG. 8), the hanging thread 3 </ b> A of the weight lowering swing 3 is applied to the intersection A of the two water threads 1 and 2, and the target T is installed at a position immediately below the weight lowering swing 3.

従来方法３（図９）（特許文献２）は、２本の水糸１、２の交点Ａに錘下げ振り３の吊り糸３Ａのフック３Ｂを引っ掛け、錘下げ振り３の直下の位置に目的物Ｔを設置する。   The conventional method 3 (FIG. 9) (Patent Document 2) hooks the hook 3B of the hanging thread 3A of the weight lowering swing 3 on the intersection A of the two water threads 1 and 2, and aims at a position immediately below the weight lowering swing 3.

特許文献１に記載の位置合せ方法は、レーザー照射部を必要とするし、照射部が照射するレーザー光線を正しく鉛直線上に沿う垂直光に設定することに困難がある。   The alignment method described in Patent Document 1 requires a laser irradiation unit, and it is difficult to correctly set the laser beam irradiated by the irradiation unit to vertical light along a vertical line.

従来方法１の単純目視では、視点Ｍを２本の水糸１、２の交点Ａの正しく鉛直上に設定できず、視線Ｌが図７の破線の如くに傾斜し、水平位置の正確な位置合せができない。   In the simple visual observation of the conventional method 1, the viewpoint M cannot be set correctly vertically above the intersection A of the two water strings 1, 2, and the line of sight L is inclined as shown by the broken line in FIG. Cannot match.

従来方法２では、２本の水糸１、２の交点Ａを動かさないように、錘下げ振り３の吊り糸３Ａをその交点Ａに当てることに神経を使う。一方の片手で錘下げ振り３を持ち、他方の片手で目的物Ｔの位置決め作業を行なうので更に難しい作業になり、位置決め及び確認に時間がかかる。   In the conventional method 2, a nerve is used to apply the hanging thread 3A of the weight swinging swing 3 to the intersection A so as not to move the intersection A of the two water threads 1 and 2. Holding the weight-lowering swing 3 with one hand and positioning the target T with the other hand makes the task more difficult and requires time for positioning and confirmation.

従来方法３では、錘下げ振り３のフック３Ｂが重力により、図９に示す如く、２本の水糸１、２の中央に行きたがり、その交点Ａが本来の位置からずれてしまう。   In the conventional method 3, the hook 3B of the weight-lowering swing 3 wants to go to the center of the two water threads 1 and 2 as shown in FIG. 9 due to gravity, and the intersection A is displaced from the original position.

The object T can be positioned and installed at the horizontal position C.

(b)錘下げ振りの吊り糸を２本の水糸の交点Ａに当てることがないので、その交点Ａが本来の位置からずれることがない。   (b) Since the hanging thread of the weight lowering swing is not applied to the intersection A of the two water threads, the intersection A is not displaced from the original position.

(c)錘下げ振りを手に持たないため、２個の錘下げ振りのそれぞれの両端を２本の水糸に引っ掛けてしまえば手離れができる。両手とも目的物Ｔを動かすことに使え、目的物Ｔの位置決め作業に使える。正しく位置決めできたことの確認も一目でできる。従って、位置決め作業を迅速、高精度化できる。   (c) Since the weight swinging swing is not held in the hand, the hands can be separated by hooking both ends of the two weight swing swings on the two water threads. Both hands can be used to move the target T and can be used for positioning the target T. You can also confirm at a glance that the positioning is correct. Therefore, the positioning operation can be performed quickly and with high accuracy.

(d)錘下げ振りが重力により各水糸に沿って該水糸の中央方向に多少滑動しても、２個の錘下げ振りの交点Ｂも、２本の水糸の交点Ａも水平位置は変わらない。従って、水平位置Ｃの位置合せ、目的物Ｔの位置決めに支障を生じない。   (d) Even if the weight-lowering swing slides slightly in the center of the water thread along each water thread due to gravity, the intersection B of the two weight-lowering swings and the intersection A of the two water threads are in the horizontal position.

(j) By assuming that the slender weight of the weight-lowering swing is a needle-like body, the thickness (width) of the slender weight when the weight-lowering swing is viewed from above is as described in (f) above. In addition, it is easy to match the thickness of the water thread.

（請求項８）
(k)錘下げ振りの長細状錘が板状体であるものとするとき、長細状錘の錘機能を確保しながら、錘下げ振りを上から視たときの長細状錘の太さ（幅）を上述(f)の如くに、水糸の太さに合せ易い。このとき、錘下げ振りを上から視たときの長細状錘の板の厚さを水糸の太さと同等にしておくことが好ましい。 (Claim 8 )
(k) When the slender weight of the weight-lowering swing is a plate-like body, the weight of the slender weight when the weight-lowering swing is viewed from above while ensuring the weight function of the slender weight. It is easy to match the thickness (width) with the thickness of the water thread as described in (f) above.

(m) An elongated weight (such as a needle-like body or a plate-like body) for swinging a weight is sufficient if the vicinity of the intersection B of the two weight-lowering swings is a long shape such as a needle or a plate. The shape of the part other than the intersection B is not questioned. Therefore, by providing additional weights at both ends of the long thin weight, the weight function of the long thin weight can be improved, and for example, lateral vibration due to wind can be prevented.

図１に示した錘下げ振り１０は、図２に示す如く、２本のそれぞれ直交するＸ方向とＹ方向の水平方向に張られた水糸１、２の交点Ａと、その交点Ａの下方で水平方向に位置合せされた水平位置Ｃを定め、当該水平位置Ｃに柱脚ピン等の目的物Ｔを位置決めして設置するために用いることができる。尚、２本の水糸１、２は、直交するＸ方向とＹ方向に張られるものに限らず、単に交差する方向に張られるものでも良い。   As shown in FIG. 2, the weight-lowering swing 10 shown in FIG. 1 includes two intersections A of water strings 1 and 2 stretched in the horizontal direction in the X direction and the Y direction orthogonal to each other, and below the intersection A. The horizontal position C aligned in the horizontal direction can be determined, and the object T such as a column base pin can be positioned and installed at the horizontal position C. The two water yarns 1 and 2 are not limited to being stretched in the orthogonal X and Y directions, but may be simply stretched in the intersecting direction.

錘下げ振り１０は、長細状錘１１の両端に、水糸１又は水糸２に引っ掛けられる紐１２、１２が取付けられる。紐１２は水糸１又は水糸２に引っ掛けるためのフック１３を備える。本実施例では、長細状錘１１を針状体２１からなるものとしている。   The weight lowering swing 10 is attached to both ends of an elongated weight 11 with strings 12 and 12 hooked on the water thread 1 or the water thread 2. The string 12 includes a hook 13 for hooking on the water yarn 1 or the water yarn 2. In the present embodiment, the elongated weight 11 is made of a needle-like body 21.

錘下げ振り１０の両端のフック１３を水糸１又は水糸２に引っ掛けたとき、長細状錘１１たる針状体２１が重力により、水糸１又は水糸２に沿ってそれらの水糸１、２の正しく鉛直直下に静止するように、針状体２１、紐１２、フック１３の重量バランスが取られている。   When the hooks 13 at both ends of the weight swinging swing 10 are hooked on the water thread 1 or the water thread 2, the needle-like body 21 that is the long thin weight 11 is caused by gravity along the water thread 1 or the water thread 2. The weight balance of the needle-like body 21, the string 12, and the hook 13 is taken so as to stand still right below 1 and 2.

従って、錘下げ振り１０を用いた位置合せ方法は以下の通りになされる（図２）。
(1)２個の錘下げ振り１０を用意する。
交点Ａを形成している２本の水糸１、２のうちの一方の水糸１に対し、該交点Ａの近傍で該交点Ａを挟む２位置に、１個の錘下げ振り１０における長細状錘１１（針状体２１）の両端のフック１３を引っ掛ける。 Therefore, the alignment method using the weight swinging swing 10 is performed as follows (FIG. 2).
(1) Prepare two weight lowering swings 10.
The length of one weight-lowering swing 10 at two positions sandwiching the intersection A in the vicinity of the intersection A with respect to one of the two water threads 1 and 2 forming the intersection A Hooks 13 at both ends of the thin weight 11 (needle 21) are hooked.

交点Ａを形成している２本の水糸１、２のうちの他方の水糸２に対し、該交点Ａの近傍で該交点Ａを挟む２位置に、もう１個の錘下げ振り１０における長細状錘１１（針状体２１）の両端のフック１３を引っ掛ける。   With respect to the other water thread 2 of the two water threads 1 and 2 forming the intersection A, the other weight-lowering swing 10 is located at two positions sandwiching the intersection A in the vicinity of the intersection A. Hooks 13 at both ends of the elongated weight 11 (needle 21) are hooked.

２個の錘下げ振り１０の長細状錘１１（針状体２１）から手を離し、長細状錘２１を重力で安定位置に静止させる。このとき、錘下げ振り１０が水糸１又は水糸２に沿って多少滑動してもかまわない。また、２個の錘下げ振り１０の高さは違っていてもかまわない。   The hand is released from the elongated weight 11 (needle 21) of the two weight-lowering swings 10, and the elongated weight 21 is stopped at a stable position by gravity. At this time, the weight lowering swing 10 may slide slightly along the water yarn 1 or the water yarn 2. The heights of the two weight swinging swings 10 may be different.

(2)２本の水糸１、２の上から見下ろし、視点Ｍを、２本の水糸１、２の交点Ａと、２本の錘下げ振り１０、１０の長細状錘１１（針状体２１）の交点Ｂとが合致して見える位置に置く。Ｌは視線を示す。視点Ｍの位置をそこから動かさず、両交点Ａ、Ｂの合致線上に水平位置Ｃを定める。両交点Ａ、Ｂの正しく鉛直線上に水平位置Ｃを定めることになる。   (2) Looking down from above the two water yarns 1 and 2, the viewpoint M is the intersection A of the two water yarns 1 and 2, the two weight-lowering swings 10 and 10 and the elongated weight 11 (needle It is placed at a position where it can be seen to coincide with the intersection B of the shape 21). L indicates a line of sight. Without moving the position of the viewpoint M, the horizontal position C is determined on the coincidence line of both intersections A and B. The horizontal position C is determined correctly on the vertical line of the intersections A and B.

(3)目的物Ｔを上述(2)の水平位置Ｃに位置決めする。
尚、目的物Ｔの上述(3)の位置決めは、例えば図３に示した通りとする。予め、ベースモルタル１０１に形成した穴１０２に無収縮グラウト１０３を充填し（図３（Ａ））、目的物Ｔたる柱脚ピン１０４の中心にボルト１０５を取付け、このボルト１０５を穴１０２の無収縮グラウト１０３内に挿入する（図３（Ｂ））。柱脚ピン１０４を穴１０２の無収縮グラウト１０３内で水平移動させ（図３（Ｃ））、柱脚ピン１０４の上面に設けてある十字状罫書き線１０６を上述(2)の水平位置Ｃに合せる（図３（Ｄ））。 (3) The object T is positioned at the horizontal position C in (2) above.
Note that the positioning of the object T in the above (3) is performed, for example, as shown in FIG. A hole 102 formed in the base mortar 101 is filled with a non-shrink grout 103 in advance (FIG. 3A), and a bolt 105 is attached to the center of the column base pin 104 serving as the object T. It inserts in the shrink grout 103 (FIG. 3 (B)). The column base pin 104 is moved horizontally within the non-shrink grout 103 of the hole 102 (FIG. 3C), and the cruciform ruled line 106 provided on the upper surface of the column base pin 104 is set to the horizontal position C of (2) above. (FIG. 3D).

ここで、図４は錘下げ振り１０の長細状錘１１（針状体２１）の太さ（幅）Ｄ2と、水糸１、２の太さＤ1との関係を示している。   Here, FIG. 4 shows the relationship between the thickness (width) D2 of the elongated weight 11 (needle 21) of the weight lowering swing 10 and the thickness D1 of the water threads 1,2.

図４（Ａ）は、上から視たとき、Ｄ2＜Ｄ1である。水糸１、２の影に長細状錘１１が隠れているため、視点Ｍが水糸１、２の中心と長細状錘１１の中心を結んだ線上からずれていても分からない。   FIG. 4A shows D2 <D1 when viewed from above. Since the elongated weight 11 is hidden in the shadow of the water threads 1 and 2, it is not known even if the viewpoint M is deviated from the line connecting the centers of the water threads 1 and 2 and the center of the elongated weight 11.

図４（Ｂ）は、上から視たとき、Ｄ2＞Ｄ1である。不必要に太い長細状錘１１の影に、目的物Ｔが隠れてしまうため（隠れる範囲Ｋ）、目的物Ｔを位置決めしにくくなる。   FIG. 4B shows D2> D1 when viewed from above. Since the target object T is hidden behind the shadow of the unnecessarily thick elongated weight 11 (the hidden range K), it is difficult to position the target object T.

図４（Ｃ）は、上から視たとき、Ｄ2＝Ｄ1である。図４（Ａ）、（Ｂ）の上述の不具合がなく、目的物Ｔを高精度に位置決めできる。   FIG. 4C shows D2 = D1 when viewed from above. The target T can be positioned with high accuracy without the above-described problems of FIGS. 4 (A) and 4 (B).

図５は錘下げ振り１０の変形例であり、長細状錘１１として、針状体２１に代わる板状体２２としたものである。このとき、板状体２２は長手方向中央に下向き凹部２２Ａを備える。   FIG. 5 shows a modified example of the weight-lowering swing 10, in which the elongated weight 11 is a plate-like body 22 that replaces the needle-like body 21. At this time, the plate-like body 22 includes a downward concave portion 22A at the center in the longitudinal direction.

図６は錘下げ振り１０の更なる変形例であり、長細状錘１１（針状体２１）（板状体２２でも可）の両端に、追加錘２３を備えたものである。   FIG. 6 shows a further modification of the weight lowering swing 10, in which additional weights 23 are provided at both ends of the elongated weight 11 (needle-like body 21) (or plate-like body 22 is also possible).

従って、図１〜図６に示した錘下げ振り１０、及び錘下げ振り１０を用いた位置合せ方法によれば、以下の作用効果を奏する。   Therefore, according to the weight lowering swing 10 and the positioning method using the weight lowering swing 10 shown in FIGS.

(a)２本の水糸１、２の交点Ａと、２個の錘下げ振り１０の交点Ｂとが、合致して見える位置に視点Ｍをもってくることにより、２本の水糸１、２の交点Ａから正しく鉛直上に視点Ｍを設定できる。両交点Ａ、Ｂを通る視線Ｌが正しく鉛直線上に沿うものになり、２本の水糸１、２の交点Ａと、その交点Ａの下方で水平方向に正しく位置合せされた水平位置Ｃを正確に定め、当該水平位置Ｃに目的物Ｔを位置決めして設置できる。   (a) When the intersection point A of the two water yarns 1 and 2 and the intersection point B of the two weight-lowering swings 10 come to coincide with each other, the viewpoint M is brought into contact, so that the two water yarns 1 and 2 The viewpoint M can be set correctly vertically above the intersection A of The line of sight L passing through both intersections A and B is correctly along the vertical line, and the intersection A of the two water threads 1 and 2 and the horizontal position C correctly aligned in the horizontal direction below the intersection A The target T can be positioned accurately and positioned at the horizontal position C.

(b)錘下げ振り１０の吊り糸を２本の水糸１、２の交点Ａに当てることがないので、その交点Ａが本来の位置からずれることがない。   (b) Since the hanging thread of the weight swinging swing 10 is not applied to the intersection A of the two water threads 1 and 2, the intersection A does not deviate from the original position.

(c)錘下げ振り１０を手に持たないため、２個の錘下げ振り１０のそれぞれの両端を２本の水糸１、２に引っ掛けてしまえば手離れができる。両手とも目的物Ｔを動かすことに使え、目的物Ｔの位置決め作業に使える。正しく位置決めできたことの確認も一目でできる。従って、位置決め作業を迅速、高精度化できる。   (c) Since the weight-lowering swing 10 is not held in the hand, the hands can be separated by hooking the two ends of the two weight-lowering swings 10 on the two water threads 1 and 2. Both hands can be used to move the target T and can be used for positioning the target T. You can also confirm at a glance that the positioning is correct. Therefore, the positioning operation can be performed quickly and with high accuracy.

(d)錘下げ振り１０が重力により各水糸１、２に沿って該水糸１、２の中央方向に多少滑動しても、２個の錘下げ振り１０の交点Ｂも、２本の水糸１、２の交点Ａも水平位置は変わらない。従って、水平位置Ｃの位置合せ、目的物Ｔの位置決めに支障を生じない。   (d) Even if the weight swinging swing 10 is slightly slid along the water threads 1 and 2 toward the center of the water threads 1 and 2 due to gravity, the intersection B of the two weight swinging swings 10 is also The horizontal position of the intersection A of the water threads 1 and 2 does not change. Therefore, there is no problem in the alignment of the horizontal position C and the positioning of the object T.

(e)錘下げ振り１０を水糸１、２に引っ掛けるだけで、自動的に重力により錘下げ振り１０の交点Ｂが正しく水糸１、２の交点Ａの鉛直下にくるので、位置決め作業を迅速、高精度化できる。   (e) Just by hooking the weight-lowering swing 10 on the water threads 1 and 2, the intersection B of the weight-lowering swing 10 automatically comes under the vertical position of the intersection A of the water threads 1 and 2 automatically due to gravity. Quick and accurate.

(f)錘下げ振り１０を上から視たとき、錘下げ振り１０の太さ（幅）Ｄ2を水糸１、２の太さＤ1に合わせることにより、水糸１、２の影に錘下げ振り１０が隠れてしまうことがないし、不必要に太い錘下げ振り１０の影に目的物Ｔが隠れてしまうことがなく、位置決め作業を損なうおそれがない。   (f) When the weight lowering swing 10 is viewed from above, the weight (width) D2 of the weight lowering swing 10 is matched with the thickness D1 of the water threads 1 and 2, thereby lowering the weight in the shadow of the water threads 1 and 2. The swing 10 is not hidden, and the object T is not hidden in the shadow of the thick weight swinging swing 10 unnecessarily, and there is no possibility of damaging the positioning operation.

(g)錘下げ振り１０が長細状錘１１にて構成されることにより、２個の錘下げ振り１０の交点Ｂを安定的に形成できる。   (g) Since the weight swinging swing 10 is constituted by the elongated weight 11, the intersection B of the two weight swinging swings 10 can be stably formed.

(h)錘下げ振り１０が長細状錘１１の両端に水糸１、２に引っ掛けられる紐１２を取付けてなるとき、２個の錘下げ振り１０の間でそれらの両端の紐１２の長さを、それらの長細状錘１１の交点Ｂにおいて長細状錘１１同士が接触しない程度に違わせておくことにより、それらの長細状錘１１が互いに接触して２本の水糸１、２の交点Ａの鉛直直下ではない位置に静止してしまうことを回避できる。   (h) When the weight lowering swing 10 is formed by attaching a string 12 to be hooked to the water threads 1 and 2 at both ends of the elongated weight 11, the length of the string 12 at both ends between the two weight lowering swings 10 By changing the length so that the long thin weights 11 do not contact each other at the intersection B of the long thin weights 11, the long thin weights 11 come into contact with each other and the two water strings 1 are in contact with each other. It can be avoided that the robot stops at a position not directly below the intersection A of the two.

(i)錘下げ振り１０の紐１２が水糸１、２に引っ掛けるためのフック１３を備えることにより、錘下げ振り１０の両端を直ちに水糸１、２に引っ掛けできる。   (i) Since the string 12 of the weight-lowering swing 10 is provided with the hooks 13 for hooking on the water threads 1 and 2, both ends of the weight-lowering swing 10 can be immediately hooked on the water threads 1 and 2.

(j)錘下げ振り１０の長細状錘１１が針状体２１であるものとすることにより、錘下げ振り１０を上から視たときの長細状錘１１の太さ（幅）Ｄ2を上述(f)の如くに、水糸１、２の太さに合せ易い。   (j) By assuming that the elongated weight 11 of the weight-lowering swing 10 is the needle-like body 21, the thickness (width) D2 of the elongated weight 11 when the weight-lowering swing 10 is viewed from above is obtained. As described above (f), it is easy to match the thickness of the water threads 1 and 2.

(k)錘下げ振り１０の長細状錘１１が板状体２２であるものとするとき、長細状錘１１の錘機能を確保しながら、錘下げ振り１０を上から視たときの長細状錘１１の太さ（幅）Ｄ2を上述(f)の如くに、水糸１、２の太さに合せ易い。このとき、錘下げ振り１０を上から視たときの長細状錘１１の板の厚さを水糸１、２の太さと同等にしておくことが好ましい。   (k) When the elongated weight 11 of the weight-lowering swing 10 is the plate-like body 22, the length when the weight-lowering swing 10 is viewed from above while ensuring the weight function of the elongated weight 11 The thickness (width) D2 of the thin weight 11 can be easily adjusted to the thickness of the water threads 1 and 2 as described above (f). At this time, it is preferable that the thickness of the elongated weight 11 when the weight lowering swing 10 is viewed from above is set to be equal to the thickness of the water threads 1 and 2.

(l)錘下げ振り１０の長細状錘１１が、上述(k)の板状体２２の長手方向中央に凹部２２Ａを有するものとするとき、長細状錘１１の錘機能を具備しながら、長細状錘１１を軽量化できる。   (l) When the elongated weight 11 of the weight lowering swing 10 has the recess 22A at the center in the longitudinal direction of the plate-like body 22 described above (k), while having the weight function of the elongated weight 11 The elongated weight 11 can be reduced in weight.

(m)錘下げ振り１０の長細状錘１１（針状体２１、板状体２２等）は２個の錘下げ振り１０の交点Ｂの近傍が針状又は板状等の長細状であれば良く、それらの交点Ｂ以外の部位の形状は問わない。従って、長細状錘１１の両端に追加錘２３を備えることにより、長細状錘１１の錘機能を向上でき、例えば風による横振れを防止できる。   (m) The elongated weight 11 (the needle-like body 21, the plate-like body 22 and the like) of the weight-lowering swing 10 has an elongated shape such as a needle-like or plate-like shape in the vicinity of the intersection B of the two weight-lowering swings 10. Any shape other than the intersection B may be used. Therefore, by providing the additional weights 23 at both ends of the long thin weight 11, the weight function of the long thin weight 11 can be improved, and for example, lateral vibration due to wind can be prevented.
