Description

【0001】
【発明の属する技術分野】
本発明は、住宅建築等の施工時に、立設される支柱の鉛直度を測定するために使用される下げ振り及びその測定保持具に関するものである。
【0002】
【従来の技術】
一般に、住宅建築等の施工時に支柱を立設する場合、支柱の鉛直度を測定し、支柱を常に鉛直な状態で立設するようにしている。この鉛直度を測定するには、例えば、支柱の一側面上部に下げ紐が巻装される下げ振り固定具を取着し、この下げ振り固定具であって前記一側面上部から所定の間隔離した位置より下げ紐を下方へ引き出す。そして、その下げ紐の下端に円錐形の下げ振りを取着し、この下げ振りの揺れが収まったところで、前記支柱の一側面下部から下げ紐までの距離を測定し、この距離と前記一側面上部から下げ紐までの所定の距離とを比較して鉛直度を測る。同様にして、前記支柱の隣接する一側面で前記と同様な作業を行い、これら隣り合う二側面の鉛直度を測定するようにしている。
【0003】
また、この他に、レーザー光線を使用して支柱の鉛直度を測定できるようにした装置がある。すなわち、支柱の一側面に沿って測定棒を平行に添設すると共に該測定棒の上端部にこの測定棒に沿ってレーザー光線を下方へ発射し得るレーザー発射装置が設けられる。測定棒の下端部には、支柱の設置面に接し、また、支柱側で軸支されかつ鉛直面内で回動し得る測定板が取着される。そして、前記レーザー光線が前記測定板の上面に設けられた中心印からどの程度ずれているかを認識することによって支柱の鉛直度を測定するようにしている。例えば、前記測定棒に対し測定板が直角になっているときは、前記レーザー光線が中心印に当たることになり、支柱が鉛直に立設されていることになる。
【0004】
【発明が解決しようとする課題】
しかしながら、前者の方法では、下げ紐に吊り下げられた下げ振りの揺れが収まり安定化するまでには時間がかなり掛かり、特に屋外でしかも強風が吹いているときは非常に長く、このため、測定作業に多くの時間を費やさなくてはならず作業性が極めて悪い。仮に、揺れが収まる前に測定してしまうと、誤差が出てしまう。更に、支柱の二側面で同様な作業を行わねばならないことから、面倒な作業を強いられるという課題が有る。一方、後者の方法では、レーザー発射装置を使用してレーザー光線を当てて測定するので、屋外であっても風に悩まされず、しかも、誤差も少なく、測定作業が能率的に行なえるものの、前記レーザー発射装置は、非常に高価であって容易に入手して使用できないという課題が有る。
【0005】
そこで、本発明は上記課題を解決すべくなされたもので、下げ振りの安定化に時間が掛からないばかりか支柱の一側面のみの測定で済み、作業能率が向上すると共に安価であって容易に入手して使用できる下げ振り及び測定保持具を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
かかる目的を達成するため、本発明に係る下げ振りは、下げ紐で吊り下げられる胴体部の外周面に少なくとも一個の鉛直面を成形し、前記鉛直面に前記下げ紐の延長線と投影して重なる延直線を引いた構成が採られる。
【0007】
また、測定保持具は、角柱状をなす支柱の一側面下部に当接され、一側面上部であって該一側面から所定の間隔離れた位置に下げ紐によって吊り下げられた下げ振りが自在に揺動するように介入し得る枠部材を有し、前記枠部材には、前記一側面と平行をなす面内で水平方向へ進退動して前記下げ振りの鉛直面に当接し得る第一停止杆と、前記一側面に対し直角をなす方向へ進退動して前記下げ振りの鉛直面に当接し得る第二停止杆と、前記一側面から前記鉛直線までの距離が測定できる計測器を設けて構成される。
【0008】
前記支柱が鉄骨である場合は、前記枠部材に磁石を設け、前記支柱の一側面に磁着して固定できるようにすることが好ましい。これにより、測定時の手間が省け一人でも作業が容易に行える。
【0009】
そこで、例えば、支柱が鉄骨であって横断面形状が正方形をなす場合、その支柱の一側面上部に磁石の付いた紐固定具を磁着して固定し、この紐固定具に下げ紐上端を掛止すると共にその下端に下げ振りを取着して吊り下げる。一方、前記支柱の一側面下部に測定保持具を当接して水平に固定し、この測定保持具に前記下げ振りを揺動自在に介入させる。この状態で、まず、下げ振りの鉛直面を第一停止杆の先端と対向させ、この第一停止杆に対し直交する方向へ揺動する下げ振りの振幅が小さくなった状態で、この下げ振りを第一停止杆の先端で停止させる。そして、一側面から鉛直線の位置を測定する。
【0010】
次に、前記下げ振りの鉛直面を第二停止杆の先端と対向させ、この第二停止杆に対し交差する方向へ揺動する下げ振りの振幅が小さくなった状態で、この下げ振りを第二停止杆の先端で停止させる。そして、一側面上部と下部とで支柱の一側端縁から下げ紐までの距離を側長具で測定する。このように、下げ振りの揺れが安定する前に該下げ振りを停止させて測定できる。また、一側面に紐固定具等と共に測定保持具を固定するのみで支柱の鉛直度が測定できる。
【0011】
【発明の実施の形態】
以下、本発明に係る下げ振り及びその測定保持具の実施の形態を図面と共に説明する。通常、支柱には鉄骨と桧等の木材があるが、この場合、下げ振りを固定するための固定具が変わるのみで、他の部材は変わらないことから先の鉄骨、例えば、横断面形状が正方形の鉄骨、について説明する。本実施の形態では、支柱Hの鉛直度を測定するに、支柱Hの上部に固定する紐固定具1と、この紐固定具1から吊り下げられる下げ紐2と、この下げ紐2の下端に取着される下げ振り3と、この下げ振り3が介入する測定保持具4と、L型の側長具5と、が使用される。
【0012】
図1は紐固定具1と下げ紐2と下げ振り3の斜視図である。紐固定具1は、金属製であって所定長さの杆体6の基端に後端面が開口する円筒状の短筒体7が一体に設けられており、この短筒体7の内部に円板状の磁石8が内装されている。なお、前記磁石8は前記後端面から後方へ食み出るようなことはない。一方、前記杆体6の先端外周面には、下げ紐2を掛止するための環状溝9が刻設されている。この環状溝9と前記短筒体7の後端面7aとの間隔は、あらかじめ所定の寸法(例えば5cm)に設定されている。
【0013】
前記紐固定具1は鉄骨製の支柱Hに使用する場合であって、桧等の木製の支柱Hに使用する場合は、図1の右側に示されるような紐固定具1aが使用される。すなわち、この紐固定具1aは金属製であって、軸杆10の基端側の外周面に螺子溝11が刻設されると共にその基端面10a中央に、支柱Hの内面に打ち込まれる打込針12が直角に突設されている。前記螺子溝11には、外周面にローレット加工を施した外嵌体13が螺合されており、その基端面13aが前記基端面10aと同一平面上で合致し得るようになっている。前記軸杆10の先端側には、前記基端面から所定の距離(例えば5cm)離れた位置に、前記と同様に下げ紐2を掛止するための環状溝14が周設されている。
【0014】
なお、図示は省略するが、前記紐固定具1aは、支柱上部であってその一側面に、基端面が当接するまで打込針12を打込んで固定する。この際、外嵌体13も回転させてその基端面13aを前記一側面に当接させる。このように、外嵌体13の基端面13aを一側面に当接させることにより、紐固定具1aの一側面に対する直角度の精度が増し、しかも、しっかり固定される。
【0015】
下げ紐2は、引っ張ることにより簡単に真直ぐに伸びる紐であって、上端部に環状部15が設けられ、下端部にSの字状のフック16が取着されている。下げ振り3は、真鍮製であって、胴体部3aの横断面が角部を円弧状に成形した正方形状に成形される略直方体形状に成形される。また、外周の各外側面17、すなわち各鉛直面17、に前記下げ紐2の延長線と投影して重なる延直線18が引かれている。下げ振り2の上部は、上方へ突出する円錐形に成形され、その中央上端部に横孔19aが貫設される。横孔19aには前記フック16を掛止する円リング19bが遊嵌されている。なお、前記下げ振り3における鉛直面17は、一個で良いが、このように周囲4面、すなわち4個設けるようにすれば、測定時に下げ振り3を水平面内で回転させなくても済むから便利である。
【0016】
次に、測定保持具4について説明する。測定保持具4は、図2に示すように一対の平行な縦板部20aと、その一端間に一体に設けられる直交状の横板部20bと、により門状に成形される枠部材20からなる。そして、前記各縦板部20aの他端に外側へ直角に折れ曲る当板部21が設けられる。前記各当板部21の外側面には紛体マグネットを混入したゴム板22が貼着される。このように、ゴム板22を貼着することからクッション性を有し、木製の支柱Hにも傷をつけずに使用でき、また粉体のマグネットを混入してなることから鉄骨の支柱Hでは、磁着力が働き、手で持っていなくても支柱Hの一側面hに固定されることになり、作業がし易い。前記両縦板部20a間の間隔は、前記下げ振り3が介入して揺動し得る寸法に設定してある。
【0017】
前記一方の縦板部20aに支持筒部23が設けられると共にこの支持筒部23に縦板部20aと直交する通孔24が開設され、この通孔24に第一停止杆25が進退自在に挿通される。この第一停止杆25の先端には、円板状の当接片26が第一停止杆25と直角に設けられている。31は、第一停止杆25の外周面に嵌着される抜止リングである。これにより、前記第一停止杆25が、前記支柱Hの一側面hと平行な面上で自在に進退動することになる。同様に、横板部20bにも支持筒部23が設けられると共にこの支持筒部23に横板部20bと直交する通孔24が開設され、この通孔24に第二停止杆27が進退自在に挿通される。また、この第二停止杆27の先端にも、円板状の当接片26が第二停止杆27と直角に設けられている。この第二停止杆27の外周面にも抜止リング31が嵌着される。これにより、前記第二停止杆27が、前記支柱Hの一側面hと直角をなす方向へ自在に進退動することになる。
【0018】
更に、前記第一停止杆25が設けられた側の縦板部20aの上下両面に計測器である物差し28が設けられる。各物差し28は、ゴム板22の前面、すなわち支柱Hの一側面hから水平面内における距離が測定できるように取り付けられる。前記横板部20bの上下部には枠部材20の水平度を見る水準器29が装着されている。ただ、この水準器29は、必ず枠部材20に一体に設ける必要はなく、別体に設けるようにし、必要なときに枠部材20の上面に乗せて使用するようにしても良い。これにより、前記測定保持具4は表裏両面が使用できるようになる。
【0019】
側長具5は、長尺杆5aと短尺杆5bとを平面L型であって直交するように設けると共に短尺杆5b側に目盛り30が設けられている。
【0020】
本発明に係る下げ振り及び測定保持具は上記構成からなり、次に、図4乃至図7に基づき使用方法について説明する。まず、図4に示すように鉄骨からなる支柱Hの一側面hの上部に紐固定具1を磁着させて固定させる。そして、上端の環状部15を杆体6の環状溝9に掛止すると共に下端のフック16を横孔19に挿通して下げ振り3を吊り下げる。前記一側面hと環状溝9、すなわち下げ紐2までの距Aは、予め設定(例えば5cm)されている。次に、図5に示すように支柱Hの一側面hの下部に、前記下げ振り3を介入させるようにして測定保持具4を固定させる。
【0021】
この測定保持具4は、その磁着力によりしっかりと固定され容易に脱落するようなことはない。このように、一側面hに磁着されるので、測定保持具4をいちいち手で持っている必要がなく作業がし易い。また、水準器29により枠部材20を水平に保持しておく。
【0022】
これにより、前記下げ振り3は枠部材20内で揺動する。この状態で、まず、下げ振り3の外周面におけるいずれかの鉛直面17を第一停止杆25先端の当接片26と対向させる。そして、図5に示すようにこの第一停止杆25に対し交差する方向、すなわち一側面hに対して直角をなす方向、へ揺動する下げ振り3の振幅が小さくなった状態で、第一停止杆25先端の当接片26により下げ振り3を停止させる。この間、揺動している下げ振り3を数回停止させて減衰させる。そして、物差し28により鉛直線18の位置を測定する。その値を前記あらかじめ設定されている寸法(例えば5cm)と比較して支柱Hの一側面hと直角をなす方向での傾きを知ることができる。この際、揺動する下げ振り3を強制的に停止させても、測定する方向と直交する方向へ押すことになるから、停止させることによる測定誤差が殆どない。
【0023】
次に、前記測定保持具4はそのままの状態にして、図6に示すように下げ振り3の鉛直面17を第二停止杆27の先端と対向させ、この第二停止杆27に対し直交する方向、すなわち一側面hに対し平行をなす方向、へ揺動する下げ振り3の振幅が小さくなった状態で、第二停止杆27先端の当接片26により下げ振り3を停止させる。この間、揺動している下げ振り3を数回停止させて減衰させる。そして、図7に示すように側長具5の長尺杆5aを一側面hの一側端縁に添わせると共に短尺杆5bの目盛り30を張り出させ、一側面hの上部と下部とで、支柱Hの一側端縁h1から下げ紐2までの距離を測定する。このようにして上下部の寸法を比較することにより、支柱Hの一側面hと平行な方向での傾きを知ることができる。この場合も、揺動する下げ振り3を強制的に停止させても、測定する方向と直交する方向へ押すことになるから、停止させることによる測定誤差が殆どない。
【0024】
このように、支柱Hの一側面hに紐固定具1等と共に測定保持具4を固定するのみで支柱Hの鉛直度が測定できる。そして、その結果を認識して必要な分量支柱Hを傾斜させて鉛直に立設するようにする。
【0025】
【発明の効果】
以上説明したように、本発明に係る下げ振り及び測定保持具にあっては、下げ振りがその胴体部の外周面に少なくとも一個の鉛直面を成形し、前記鉛直面に下げ紐の延長線と投影して重なる鉛直線を引いてなり、この揺動する下げ振りを誤差がほとんど出ないような位置で停止させて、前記支柱の一側面からの距離を測定するようにしたので、下げ振りの安定化に時間が掛からず簡単に測定でき、しかも、一側面に紐固定具等と共に測定保持具を固定するのみで支柱の鉛直度が測定できることとなり、これにより作業能率が格段に向上するという効果がある。
【0026】
また、簡単な構成であることから、製作も容易であり製作コストを低廉になし得るという効果が有る。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plumb bob used for measuring the verticality of an upright supporting column at the time of construction of a residential building or the like, and a measurement holder for the plumb bob.
[0002]
[Prior art]
In general, when erecting a support when constructing a house or the like, the verticality of the support is measured, and the support is always installed in an upright state. In order to measure the verticality, for example, a plumb bobbin fixed around which a down string is wound is attached to the upper side of one side of the column, and the plumb bobbin is separated from the upper side of the one side by a predetermined distance. Pull out the lower string from the position where it was set. Attach a conical down swing to the lower end of the down strap, and when the swing of the down swing is settled, measure the distance from the lower portion of one side of the support to the down strap, and determine this distance and the one side. The verticality is measured by comparing with a predetermined distance from the upper part to the hanging string. Similarly, the same operation as described above is performed on one adjacent side surface of the column, and the verticality of these two adjacent side surfaces is measured.
[0003]
In addition, there is an apparatus which can measure the verticality of a support using a laser beam. That is, a laser emitting device capable of emitting a laser beam downward along the measuring rod is provided at the upper end of the measuring rod with a measuring rod attached in parallel along one side surface of the support. At the lower end of the measuring rod, a measuring plate that is in contact with the installation surface of the column, is pivotally supported on the column side, and can rotate in a vertical plane is attached. Then, the verticality of the column is measured by recognizing how much the laser beam deviates from the center mark provided on the upper surface of the measurement plate. For example, when the measuring plate is at right angles to the measuring rod, the laser beam hits the center mark, and the columns are standing upright.
[0004]
[Problems to be solved by the invention]
However, in the former method, it takes a considerable amount of time for the swing of the bobbin hanging on the bobbin to stabilize and stabilize, and it is extremely long especially when outdoors and strong winds are blowing. A lot of time must be spent for work, and workability is extremely poor. If the measurement is performed before the vibration stops, an error will occur. Furthermore, since the same work must be performed on the two sides of the support, there is a problem that a troublesome work is forced. On the other hand, in the latter method, since the measurement is performed by irradiating a laser beam using a laser emitting device, even if it is outdoors, it is not bothered by the wind, and the error is small, and the measurement operation can be performed efficiently. The launching device has the problem that it is very expensive and cannot be easily obtained and used.
[0005]
Therefore, the present invention has been made in order to solve the above-mentioned problem, and not only does it not take much time to stabilize the down swing, but only the measurement of one side of the support is required, and the work efficiency is improved, and it is inexpensive and easy. It is an object of the present invention to provide a plumb bob and a measuring holder which can be obtained and used.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the bobber according to the present invention forms at least one vertical surface on the outer peripheral surface of the body portion suspended by the bobbin, and projects an extension of the bobbin on the vertical surface. A configuration in which overlapping extending straight lines are drawn is employed.
[0007]
In addition, the measurement holder is abutted on the lower part of one side of the columnar pillar, and the lower part can be freely swung by the lower string at the upper part of the one side and separated from the one side by a predetermined distance. A first stop, which has a frame member that can intervene in a swinging manner, wherein the frame member moves forward and backward in a horizontal direction in a plane parallel to the one side surface and can abut on the vertical surface of the downward swing. A rod, a second stop rod which can move forward and backward in a direction perpendicular to the one side surface and contact the vertical surface of the down swing, and a measuring device capable of measuring a distance from the one side surface to the vertical line are provided. It is composed.
[0008]
When the support is a steel frame, it is preferable that a magnet is provided on the frame member so that the support can be magnetically attached to one side surface of the support and fixed. As a result, the labor at the time of measurement can be saved and the work can be easily performed by one person.
[0009]
Therefore, for example, when the column is a steel frame and the cross-sectional shape is a square, a string fixing device with a magnet is magnetically attached to an upper portion of one side of the column, and the upper end of the lowering string is attached to the string fixing device. At the same time, it is hung down at the lower end with a swing. On the other hand, a measuring holder is brought into contact with the lower part of one side surface of the support column and fixed horizontally, and the downward swing is swingably interposed in the measuring holder. In this state, first, the vertical plane of the down swing is opposed to the tip of the first stop rod, and the swing of the down swing swinging in a direction orthogonal to the first stop rod is reduced, and the down swing is performed. At the tip of the first stop rod. Then, the position of the vertical line is measured from one side.
[0010]
Next, with the vertical surface of the down swing facing the tip of the second stop rod, the down swing swinging in the direction intersecting with the second stop rod is reduced, and the down swing is performed in the second direction. Stop at the tip of the double stop rod. Then, the distance from one side edge of the column to the lower string is measured with the side long tool at the upper part and the lower part on one side. In this way, measurement can be performed by stopping the down swing before the down swing is stabilized. Further, the verticality of the support can be measured only by fixing the measurement holder together with the string fixing device or the like on one side surface.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a plumb bob and its measurement holder according to the present invention will be described with reference to the drawings. Usually, there are steel pillars and wood such as hinoki on the pillars, but in this case, only the fixture for fixing the plumb bob changes, and the other members do not change. A square steel frame will be described. In the present embodiment, in order to measure the verticality of the support H, a string fixing device 1 fixed to the upper portion of the support H, a hanging string 2 suspended from the string fixing device 1, and a lower end of the hanging string 2 The plunger 3 to be attached, the measuring holder 4 on which the plunger 3 intervenes, and the L-shaped side long tool 5 are used.

The distance between the annular groove 9 and the rear end face 7a of the short cylinder 7 is set to a predetermined dimension (for example, 5 cm) in advance.
[0013]
The string fixing device 1 is used for a column H made of steel, and when used for a wooden column H such as cypress, a string fixing device 1a as shown on the right side of FIG. 1 is used. That is, the string fixing device 1a is made of metal, and a screw groove 11 is engraved on the outer peripheral surface on the base end side of the shaft rod 10, and the center of the base end surface 10a is driven into the inner surface of the column H. The needle 12 projects at a right angle. An external fitting 13 having a knurled outer peripheral surface is screwed into the screw groove 11 so that a base end surface 13a thereof can coincide with the base end surface 10a on the same plane. An annular groove 14 is provided around the distal end of the shaft 10 at a predetermined distance (for example, 5 cm) away from the base end surface to hold the hanging string 2 in the same manner as described above.
[0014]
Although not shown, the string fixing tool 1a is fixed by driving the driving needle 12 into the upper part of the column and on one side surface thereof until the base end surface thereof comes into contact. At this time, the outer fitting body 13 is also rotated to bring its base end face 13a into contact with the one side face. As described above, by bringing the base end surface 13a of the outer fitting body 13 into contact with one side surface, the accuracy of the perpendicularity to one side surface of the string fixing device 1a is increased, and the fixing is firmly performed.

Further, an extended straight line 18 is projected on each outer side surface 17 of the outer periphery, that is, each vertical surface 17 so as to overlap with an extension of the hanging string 2. The upper part of the bobbin 2 is formed in a conical shape protruding upward, and a lateral hole 19a is formed through the central upper end. A circular ring 19b for hooking the hook 16 is loosely fitted in the lateral hole 19a. The number of the vertical planes 17 in the above-mentioned bobbin 3 may be one, but providing such four peripheral surfaces, that is, four, makes it unnecessary to rotate the bobbin 3 in a horizontal plane at the time of measurement. It is.
[0016]
Next, the measurement holder 4 will be described. As shown in FIG. 2, the measurement holder 4 is formed by a pair of parallel vertical plate portions 20 a and an orthogonal horizontal plate portion 20 b integrally provided between one ends thereof. Become. The other end of each of the vertical plate portions 20a is provided with a contact plate portion 21 that is bent outward at a right angle. A rubber plate 22 mixed with a powder magnet is adhered to the outer surface of each of the contact plate portions 21. As described above, the rubber plate 22 is adhered, so that it has a cushioning property, can be used without damaging the wooden support H, and since the powder magnet is mixed, the steel support H can be used. The magnetic force acts, and the column H is fixed to one side surface h of the column H even if it is not held by hand, which facilitates the work. The distance between the two vertical plate portions 20a is set to a size that allows the swinging of the down swing 3 to intervene.
[0017]
A support tube portion 23 is provided on the one vertical plate portion 20a, and a through hole 24 is formed in the support tube portion 23 so as to be orthogonal to the vertical plate portion 20a. It is inserted. At the tip of the first stop rod 25, a disc-shaped contact piece 26 is provided at right angles to the first stop rod 25. Reference numeral 31 denotes a retaining ring fitted on the outer peripheral surface of the first stop rod 25. Thereby, the first stop rod 25 freely moves forward and backward on a plane parallel to one side surface h of the support post H. Similarly, a support cylinder 23 is also provided on the horizontal plate 20b, and a through-hole 24 is formed in the support cylinder 23 at right angles to the horizontal plate 20b. Is inserted through. Also, a disc-shaped contact piece 26 is provided at the end of the second stop rod 27 at right angles to the second stop rod 27. The retaining ring 31 is also fitted on the outer peripheral surface of the second stop rod 27. Thereby, the second stop rod 27 freely moves forward and backward in a direction perpendicular to one side surface h of the support post H.
[0018]
Further, a ruler 28 as a measuring instrument is provided on both upper and lower surfaces of the vertical plate portion 20a on which the first stop rod 25 is provided. Each ruler 28 is attached so that the distance in the horizontal plane from the front surface of the rubber plate 22, that is, one side surface h of the column H can be measured. At the upper and lower portions of the horizontal plate portion 20b, a level 29 for checking the level of the frame member 20 is mounted. However, the level 29 need not always be provided integrally with the frame member 20, but may be provided separately, and may be used on the upper surface of the frame member 20 when necessary. As a result, both sides of the measurement holder 4 can be used.
[0019]
The side long tool 5 is provided with a long rod 5a and a short rod 5b in a plane L shape so as to be orthogonal to each other, and a scale 30 is provided on the short rod 5b side.
[0020]
The plunger and the measuring holder according to the present invention have the above-described configuration. Next, a method of use will be described with reference to FIGS. First, as shown in FIG. 4, the string fixing device 1 is magnetically fixed to an upper portion of one side surface h of a column H made of a steel frame and fixed. Then, the annular portion 15 at the upper end is hooked into the annular groove 9 of the rod 6 and the hook 16 at the lower end is inserted into the lateral hole 19 to suspend the swing down 3. The distance A from the one side surface h to the annular groove 9, that is, the hanging string 2, is set in advance (for example, 5 cm). Next, as shown in FIG. 5, the measurement holder 4 is fixed to the lower part of one side surface h of the column H so as to interpose the down swing 3.
[0021]
The measurement holder 4 is firmly fixed by its magnetic adhesion and does not easily fall off. As described above, since the magnetic member is magnetically attached to one side surface h, it is not necessary to hold the measuring holder 4 by hand, and the work is easy. The frame member 20 is held horizontally by the level 29.
[0022]
Thereby, the down swing 3 swings in the frame member 20. In this state, first, any vertical surface 17 on the outer peripheral surface of the down swing 3 is made to face the contact piece 26 at the tip of the first stop rod 25. Then, as shown in FIG. 5, in a state where the amplitude of the down swing 3 that swings in the direction intersecting with the first stop rod 25, that is, in the direction perpendicular to the one side surface h, becomes smaller, The down swing 3 is stopped by the contact piece 26 at the tip of the stop rod 25. During this time, the swinging down swing 3 is stopped and damped several times. Then, the position of the vertical line 18 is measured by the ruler 28. By comparing the value with the previously set dimension (for example, 5 cm), it is possible to know the inclination in a direction perpendicular to one side surface h of the support H. At this time, even if the swinging down swing 3 is forcibly stopped, the swinging down swing 3 is pushed in a direction orthogonal to the direction in which the measurement is performed.
[0023]
Next, the measurement holder 4 is left as it is, and the vertical surface 17 of the plunger 3 is opposed to the tip of the second stop rod 27 as shown in FIG. The down swing 3 is stopped by the contact piece 26 at the tip of the second stop rod 27 in a state in which the amplitude of the down swing 3 swinging in the direction, that is, the direction parallel to the one side surface h is reduced. During this time, the swinging down swing 3 is stopped and damped several times. Then, as shown in FIG. 7, the long rod 5a of the side long tool 5 is attached to one side edge of one side h, and the scale 30 of the short rod 5b is extended, so that the upper and lower parts of the one side h are joined together. The distance from one side edge h1 of the support H to the hanging string 2 is measured. By comparing the dimensions of the upper and lower parts in this way, it is possible to know the inclination in a direction parallel to one side surface h of the column H. In this case as well, even if the swinging down swing 3 is forcibly stopped, the swinging down swing 3 is pushed in a direction orthogonal to the direction of measurement, so that there is almost no measurement error due to the stop.
[0024]
As described above, the verticality of the support H can be measured only by fixing the measurement holder 4 together with the string fixing tool 1 and the like to one side h of the support H. Then, upon recognizing the result, the necessary quantity supporting column H is inclined and vertically erected.
[0025]
【The invention's effect】
As described above, in the plunger and the measurement holder according to the present invention, the plumb bob forms at least one vertical surface on the outer peripheral surface of the body portion, and an extension of the lower string on the vertical surface. By projecting and drawing overlapping vertical lines, this swinging down swing was stopped at a position where almost no error appeared, and the distance from one side of the support was measured, so that the down swing The stabilization does not take much time and can be easily measured.In addition, the verticality of the column can be measured only by fixing the measuring holder together with the string fixing device on one side, thereby significantly improving the work efficiency. There is.
[0026]
In addition, since the configuration is simple, there is an effect that the production is easy and the production cost can be reduced.
