2. Description of the Related Art Conventionally, in order to build and install various kinds of predetermined structures on a building surface, a center position of each divided cloth foundation is set, a core position is indexed and measured, and both ends of the building surface are measured. By laying a core thread or the like between the surveying piles that have been positioned and driven, the core position is displayed on the construction surface. Then, the foundation form is assembled so as to excavate the foundation moat corresponding to the stretched and displayed core yarn and construct a predetermined foundation on the bottom surface of the foundation moat.

In assembling the basic formwork, a core is set on the bottom surface of the foundation moat, and the left and right formwork are framed at predetermined distances from the centerline. It is something that is fixed.

At this time, although the display of the core core position by the core yarn measured and set on the construction surface can be confirmed on the construction surface, in the foundation moat excavated and formed on the construction surface, this foundation moat is Since it is dug downward from the construction surface, it is difficult to confirm the exact position easily due to an illusion or the like by the operator's own visual observation even if it is directly below the vertical line of the core yarn. Therefore, in the past, a lumber that was placed so as to straddle the opening of a foundation moat was hung from a lumber that was attached to the lower end of the lumber, and it was set on one survey pile position. By looking at the transits etc. that you made and moving and adjusting the lower swing position on the tree,
It was set by re-measurement as the core position through the position below the weight.

[0005]

[Problems to be Solved by the Invention] However, even if the plumb bob position on the lumber can be accurately moved and adjusted by a transit or the like, the plumb bob hanging from the lumber connects the weight to the lower end of the plumb bobbin. Since it is only done, it takes time to stop at a certain position due to rotation, swinging, etc. due to vibration accompanying movement of trees, vibration of various work vehicles transmitted to the ground, wind force, etc. It was a thing. Not only that, moving the tree is troublesome, and if you set an incorrect center line position by omitting the troublesome work, the foundations and structures that will be framed thereafter will be distorted. It was inconvenient.

Therefore, the present invention has been devised in view of the existing circumstances such as the above, and the position of the core is surely and easily measured on the bottom surface of the foundation moat formed by excavation on the construction surface. It is an object of the present invention to provide a marking down swinging device which can be set and can perform marking work in a short time and improve work efficiency.

[0007]

In order to achieve the above-mentioned object, according to the present invention, the footrest 1 arranged in the foundation moat H formed by excavation on the construction surface and the footrest 1 are extendable or bendable. Arm body 1 mounted on the base 1 so that it can swing freely
1 is provided with a plumb bob mechanism 10 formed by connecting a plumb bob 15 made of a rigid material having a measured end portion 18 projecting above the foundation moat H in an upper part thereof in a swingable hanging state. The swinging material 15 is supported by a supporting frame 17 having a connecting arm 16 having a shaft structure that is swingably connected to the tip of the arm body 11, a measured end portion 18 at an upper portion, and a lowering swinging body 19 at a lower end. The slide rod 21 slidably inserted in the frame 17 in the vertical direction, and the slide rod 21 supporting the slide frame 21.
It is characterized by comprising a locking means 22 for locking inside.

[0008]

In the bobbin swinging device for marking out according to the present invention, the footrest 1 is supported by a standing leg at an arbitrary position in the foundation moat H, and is placed and moved along the center line position to move the bobbin swinging mechanism 10 Makes the position of the measured end portion 18 on the upper part of the plumb bob 15 at the time of measurement correspond to the preset core position and allows the position of the plumb bob 15 itself to be confirmed from a distance.

The arm body 11 of the plumb bob mechanism 10
Means to make the plumbing swinging material 15 made of a rigid material always pendant along the vertical direction without unnecessarily shaking without determining the direction, and after being positioned by the measured end portion 18, the plumbing swinging material 15 is The lower position of the plumb bob 19 in the lower portion is passed through to promptly identify it as the core position.

The plumb bob 15 has a slide rod 21 slidable with respect to the support frame 17 and is set to a length corresponding to the depth of the foundation moat H and the like. When the slide rod 21 falls by its own weight, the plumb bob 19 passes on the bottom surface of the foundation moat H in a point shape to display the core position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings.
It is a foot stand composed of three legs 2 that can be freely opened and closed and is connected to the bottom surface of the base 3, and with the legs 2 expanded, the foundation moat H
It is designed to stand inside. In addition, this foot stand 1
Is not limited to the tripod structure as shown in the figure, and may be formed in a bar shape that extends over a moat opening in the construction surface of the foundation moat H, for example. It is enough to support it.

A plumb bob mechanism 10 is mounted on the pedestal 1. The plumb bob mechanism 10 itself is capable of expanding and contracting or bending in the horizontal direction so that it can be swiveled on the platform 3. The mounted arm body 11 and the measured end portion (center point) 18 protruding above the foundation moat H are provided on the upper side, and the swing body 19 is provided on the lower end, respectively, so that the arm body 11 can swing freely at the tip of the arm body 11. Rigid plumb bob 1 linked together
5 and.

The arm body 11 shown in the drawing is a main arm 13 rotatably mounted at a substantially central position of the base 3 via a shaft means 12, and a bendable end of the main arm 13. It is formed with the auxiliary arm 14 connected to it. The main arm 13 is formed by inserting a shaft material having a flange structure, which is inserted into the rear end of the main arm 13, into the base plate 3 and screwing the shaft member 1.
It is mounted so that it can be freely swiveled on the base plate 3 via 2, and the main arm 13 itself is formed of a solid material. The auxiliary arm 14 is formed, for example, by crushing the rear end of the pipe material, and the crushed portion at the rear end is inserted into a U-shaped connecting portion formed at the tip of the main arm 13 when viewed from the side surface. By being supported by a shaft, it is connected to the main arm 13 in a state in which it can swing in the left-right direction (FIGS. 2 and 3).
reference).

On the other hand, the plumb bob 15 has a support frame 17 having a connecting arm 16 of a shaft structure which is swingably connected to the tip of the arm 11, a measured end 18 at the upper part, and a plumb bob 19 at the lower end. And a locking means 22 that locks the slide rod 21 in the support frame 17. The slide rod 21 is slidably inserted in the support frame 17 in the vertical direction.

The support frame 17 has a connecting arm 1 on the outside thereof.
6 is projectingly provided, and the connecting arm 16 itself is loosely fitted into, for example, the distal end of the cylindrical auxiliary arm 14, so that the slide rod 21 itself is drooped by its own weight. It is designed so that it can be freely swung and shaken as it is smoothly swung in only one direction. The connecting arm 16 may be detachable from the arm body 11, and can be disassembled when it is not needed to make it convenient for carrying and storing.

The end portion 18 to be measured formed on the upper end of the slide rod 21 is formed, for example, in the shape of a pin, and the base 1
It is made to project above the foundation moat H, which is above the base 3, so that it can be visually confirmed when looking through the transit T or the like when measuring the core or the like.

Further, the plumb bob 19 is, for example, a conventionally known one which is formed in an inverted conical shape, and is connected to the lower end of the slide rod 21 by a screw or the like, and the slide rod 21 is attached by its own weight. Can be held vertically, and depending on the case, the core position can be pierced in a point shape by passing through the bottom surface of the foundation moat H by the drop action of the slide rod 21 by releasing the locking means 22 so that the position can be clearly indicated. Further, a pressure stamp type marking mechanism is attached to the plumb bob 19 or the plumb bob 1
9 itself may be used as a marking mechanism, and it is also possible to imprint a display mark at the core position on the bottom surface of the foundation moat H by a pressing operation, a dropping action, or the like.

The locking means 22 is, for example, a screw material screwed from the outside of the support frame 17 into the support frame 17 itself so that its tip is abutted against the outer surface of the slide rod 21, and is tightened. By loosening, the slide rod 21 itself is fixed or can be freely slid vertically (see FIG. 4).

Although the support frame 17 and the slide rod 21 themselves are formed in a plane and have a substantially rectangular shape in the drawing, it is of course possible to make them into a circular shape or another shape, and they can be arbitrarily selected. is there.

Although not shown in the drawings, the plumb bob 15 has a measured end portion 18 projecting above the base 3 by a predetermined length at the upper portion thereof, for example, a channel having a C-shaped cross section. It consists of a main body of a plumb bob and a body of a plumb bob that is slidably inserted into the body of a plumb bob so that a slight sliding resistance is caused by the rubber material attached to the inner surface of the bob. The lower end of the swing aid is
It may be formed at an acute angle so as to clearly show the core position below this (not shown).

Next, to explain an example of the use of this, as shown in FIG. 5, when the core wire or the like is passed through the bottom of the foundation moat H formed by excavation on the construction surface and measurement is performed again, the measurement setting is made before excavation. Set the transit T at the P position of the survey pile.
Next, place the device for swinging the device in the foundation moat H,
While looking through the measured end portion 18 above the plumbing swinging member 15 by the transit T, the extension / contraction length or the bending angle of the arm body 11 is adjusted so that the measured end portion 18 matches the passing core line position. In this way, the lower position on the vertical line of the plumb bob 19 at the lower part of the plumb bob 15 when the measured end portion 18 is aligned with the bobbin core position is set as the bobbin core position on the bottom surface of the foundation moat H. Since the plumb bob 15 itself is made of a rigid material when setting the bobbin position, the plumb bob 19 at the lower portion thereof does not rotate and swivel, and the bob core position can be clearly indicated. At this time, if necessary, if the fixing of the slide rod 21 by the locking means 22 is released and the slide rod 21 is dropped by its own weight, the plumb bob 19 passes through the bottom surface of the foundation moat H to make the core position point-like. pierce.

At this time, the foot stand 1 has a tripod structure in which three extendable leg members 2 which are erected in the foundation moat H are connected to the bottom surface of the base 3 so that they can be opened and closed. Thus, the pedestal can be supported at any position in the foundation moat H, and by opening and closing it, the arrangement and movement along the center line position can be freely performed, and the position to be measured in the foundation moat H can be set. Can be set immediately.

Also, the arm body 11 of the plumb bob 10
The auxiliary arm 14 is foldably connected to the tip of the main arm 13 rotatably attached to the base 3 of the pedestal 1 through the shaft means 12 via the shaft means 12. By the bending adjustment, the plumb bob mechanism 10 itself can be moved and finely adjusted without moving the pedestal 1 itself, and the plumb bob mechanism 10 is positioned at a core position measured by looking through the transit T or the like. be able to.

EFFECT OF THE INVENTION The present invention is constructed as described above, and for this reason, on the bottom surface of the foundation moat H formed by excavation on the construction surface, directly below the core line preset on the construction surface. As a result, the center line position can be reliably and easily measured and set. Moreover, unlike the conventional case, the center line position is clearly indicated by the lowering swing member 15 made of a rigid material that does not depend on the instruction line by the lower swing line which is easily rotated and swung. Since this is done, the marking work can be performed in a short time, and the work efficiency can be further improved.

In other words, this is the basic moat H
The base 1 that is placed in the
This is because the swingable arm body 11 is provided with the plumb swing mechanism 10 in which the rigid swing plumbing material 15 having the measured end portion 18 in the upper part is connected in a swingable hanging state. As a result, the core position can be easily and quickly reset on the bottom surface of the foundation moat excavated on the construction surface.

Further, the plumb bob 15 in the plumb bob mechanism 10 is made of a rigid material which is swingably connected to the tip of the arm 11 via the connecting arm 16 so as to be hung by its own weight. When drooping, there is no unnecessary shaking such as rotating and turning without determining the direction, and even if it swings in one direction like a pendulum, it is always in a hanging state along the vertical direction. . Therefore, after being positioned by the upper measured end portion 18, the lower position of the plumb bob 19 at the lower end of the plumb bob 15 can be swiftly specified as the core position, and the plumb bobbin can be used as in the conventional case. By doing so, the work can be quickly performed without the operator's urgency while waiting for the stop.

Further, in the plumb bob 15, the upper end of the plumb bob 15 serves as the measured end portion 18 projecting above the foundation moat H, so that the plumb bob 15 itself when looking through the transit T or the like. The position of can be confirmed from a distance, and measurement work can be easily performed.

Moreover, the plumb bob 15 is made up of the arm 11
Since the slide rod 21 having the measured end portion 18 at the upper portion and the swinging body 19 at the lower end is slidably inserted into the support frame 17 that is swingably connected to the tip end through the connecting arm 16, By sliding the slide rod 21 in the support frame 17, for example, the entire length can be arbitrarily adjusted and set according to the depth of the foundation moat H. Further, since the slide rod 21 is locked by the locking means 22 in the support frame 17, if the locking of the slide rod 21 by the locking means 22 is released and the slide rod 21 is dropped by its own weight, the swinging motion is lowered. The body 19 pierces the bottom of the foundation moat H, the position of the core can be clearly displayed in a point shape, and it is not necessary to prepare a special mark display tool, which is convenient.
