Description

  The present invention relates to an inking aid used when inking at a position where there is a level difference from the floor on which a transit or the like is installed, or a position where it cannot be seen by an obstacle such as a reinforcing bar.

When building a building with reinforced concrete, etc., based on the boundary line with the adjacent land and the road boundary line, the building position is displayed and the foundation work is carried out. According to the design drawing, the pillar, beam, floor, wall, etc. It is necessary to cast concrete. In that case, a reference line is marked on the reference plane to make a background ink, and the four corners are set as reference points. Then, vertical through holes are provided at the four corners of the upper floor, the swing is lowered, the vertical direction is measured, and the reference point is moved to the floor of the upper floor. Based on the reference point, a reference line is drawn on the floor according to the design drawing. However, since this reference line is hidden when concrete is placed on the wall surface, the reference points are positioned at the four corners inside about 1 meter each in the XY direction, and the length and angle between the four points by the transit, the reference line and After confirming concurrency, draw a good ink and record its position. In the vertical direction, there is a method using a laser oscillator and a light receiver instead of swinging down. After the concrete of the frame such as pillars, walls, beams, etc. is laid based on the reference line, finishing work of floors and ceilings of each room, partitioning work, electrical work, stair work, etc. Ink painting for child ink will be performed.
However, when construction of ink and child ink, if there are obstacles such as reinforcing bars on the line, or if there is a difference in the level of bathrooms or stairs, you will not be able to see the target point from the transit. Sometimes it takes a lot of time and effort.
Therefore, even in the presence of obstacles, it is extended through a plurality of joints that can be bent from a fixed part that is fixed to a reference point to measure the ink easily, quickly, and accurately. The arm part provided with the point, the sensor provided for each joint of the arm part to detect the displacement amount of the joint, and the measurement for calculating and displaying the relative positional relationship between the reference point and the measurement point from the detected displacement amount An inking device including a coordinate display unit has been disclosed (Patent Document 1).
Also, two laser surveying instruments are arranged at two fixed points, a vertical laser beam is formed at a position where the two vertical laser surfaces intersect, and the vertical laser projected onto the floor surface even on a floor surface with a level difference The position of the reference point is determined by the position of the light beam, or the intersection coordinates of the laser light are obtained using a sensor panel that can detect the laser light, and the vertical vertical laser light generator placed below the sensor panel is used to A method of positioning a floor surface with a laser spot at the same time as irradiating an intersection is disclosed (Patent Document 2).

Japanese Patent No. 2768149 Japanese Patent Laid-Open No. 10-239057

However, although the method described in Patent Document 1 is effective for inking near the floor surface with a step, the structure is complicated and skill is required for handling. In addition, the method described in Patent Document 2 uses many optical devices such as a laser surveying instrument, a sensor panel, and a vertical vertical laser beam generator, and its accuracy maintenance is troublesome.
In view of the above circumstances, the present invention can easily and accurately position a point as a reference even when there is a step and cannot be seen, or when there is an obstacle such as a reinforcing bar and the line of sight cannot be seen. It is an object of the present invention to provide an inking aid that is simple and does not require the effort of accuracy adjustment.

The inking aid of the present invention includes a flat plate member having a predetermined length with a central portion cut out in the longitudinal direction, and a sliding member that is externally fitted to the flat plate member and freely slides in the longitudinal direction of the flat member. A hollow first tubular member fitted in a hole penetrating the sliding member sandwiching the central portion of the flat plate member and fixed perpendicularly to the sliding member, and the first tubular member moved A first rod body of a predetermined length that is freely fitted and wound upward by a wound spring, a leg portion that is installed on the bottom surface of the flat plate member and whose height can be adjusted, and the flat plate member And a bubble jar for discriminating whether or not is horizontal, and depressing the first rod with a finger to mark the ink at a predetermined position.
In this way, the first rod body having a predetermined length is installed vertically and can move freely in the horizontal direction. Therefore, if the first rod body is moved in the target direction seen from the transit, there is a level difference. In addition to being able to position the target position on the floor surface, the first rod can be moved freely up and down by the spring force of the spring, so that the ink can be easily drawn at the positioned position.
In that case, it is preferable that the first rod has a light emitting member at the top and a recording means at the bottom, and the flat plate member has a scale on the side surface,
It is preferable that the sliding member has a window on which a scale can be visually recognized on a side surface, and a position where the first rod body is fitted is described in the window.
If the upper part of the first rod emits light, it is easy to see from the transit even in the dark, and if the lower part is made of a writing instrument, it is easy to make ink. Furthermore, if the window which can visually recognize the scale attached | subjected to the flat plate member is provided in the side surface of the sliding member and the position which the 1st rod body fits is described, the distance which the 1st rod body was moved will be known.
Further, in parallel with the first cylindrical member, a second cylindrical member installed on each of both end faces of the flat plate member and the second cylindrical member are movably fitted, and are wound upward by a wound spring. A second rod body, and the second rod body is pushed down to confirm that the first rod body moves on a predetermined line. Even if the target point cannot be seen from the transit, place the inking aid on the line of the master ink, move the first rod to a position where it can be seen from the transit, and shift the angle to that point. If the measurement is performed, the distance from the transit to the target point is known, so that the first rod can be moved to the target point and ink can be drawn out.
Alternatively, the position and the side where the first cylindrical member is fixed on the bottom surface of the sliding member, and the linear third rod body rotatably supported and the angle at which the third rod body rotates. By adjusting the arrangement of the inking aid so that the first rod and the third rod can be seen in a straight line even when the ink is not drawn, Can be placed in the correct position.
Therefore, the direction of the target point from the transit installed at the predetermined position is not visible, but when the first rod located near the target point is visible, the distance from the transit to the target point And a distance from which the first rod is moved to the target point based on an angle between the direction of the target point and a direction in which the first rod can be viewed, and the target is moved by the moved first rod. You can mark the spot.

  According to the inking aid of the present invention, even if there is a step and cannot be seen from the transit, or even if there is an obstacle in the middle and cannot be seen from the transit, accurate inking is not performed. Can do. In addition, since an optical device such as a laser is not used and the structure is simple, accuracy adjustment is unnecessary.

[First Embodiment]
1-4 is a figure which shows an example of the inking aid of 1st Embodiment, FIG. 1 is a top view, FIG. 2 is a front view, FIG. 3 is a rear view, FIG. 4 is a bottom view.
The inking aid 1 shown in FIG. 1 to FIG. 4 has an elongated flat plate member 10 having a length of about 30 cm with a central portion 11 cut out in the longitudinal direction and a rectangular hollow cross section. The sliding member 20 having a length of about 5 cm that is fitted and slid in the longitudinal direction, the leg portion 30 that is installed at two places on the bottom surface 12 of the flat plate member and can be freely adjusted in height, and the sliding member 20 In order to determine whether or not the moving surface is horizontal, an air bubble 35 attached to the sliding member 20 is provided. The sliding member 20 is provided with a first cylindrical member 21 penetrating vertically. The first cylindrical member 21 is wound with a string spring 24 and has a length of 15 cm to 20 cm. One rod 15 is inserted.
Here, the flat plate member 10, the sliding member 20, the leg portion 30, and the first cylindrical member 21 are formed using a metal plate such as stainless steel, and the first rod 15 is formed using a hard resin. However, it is not always necessary to limit them. The numerical values shown here are merely examples, and the numerical values are not necessarily limited to those.

As shown in FIG. 2, the flat plate member 10 has scales 13 on the side surfaces, and fitting members 31 that fix the leg portions 30 are fitted into both ends.
The fitting member 31 is a hollow member having a rectangular cross section, and one end side is open, but the other end side is closed. Then, a through hole (not shown) 25 that penetrates both the fitting member 31 and the flat plate member 10 is provided from the top surface side to the bottom surface side with the flat plate member 10 interposed therebetween, and a female screw (appears in the drawing) is provided in the through hole 25. 25a is engraved.
Since the scale 13 is attached by engraving a thin line on a smooth metal surface, it may be colored by imprinting a paint or the like on the engraved thin line.
As shown in FIG. 2 or FIG. 3, the leg portion 30 includes a disk-shaped member 33 and a male screw 36 with a knob that is fixed to the disk-shaped member 33 and screwed into the through hole of the fitting member 31. Yes. Then, the height can be freely adjusted by turning the male screw with knob 36 left and right. Therefore, it is confirmed whether or not the sliding surface of the sliding member 20 is horizontal by the air bubble 35 attached to the sliding member 20, and the horizontal is maintained, and the upper portion 15a of the first rod 15 is moved from the transit. The height of the leg part 30 is adjusted so that it can be visually recognized.
Further, as shown in FIG. 4, the disk-like member 33 has a diameter approximately the same as the width of the flat plate member 10 so that it can be sat down, and a magnet plate or the like is fitted on the bottom surface. Yes. When a magnet is fitted on the bottom surface of the leg 30, when a metal member such as a flat deck is used as a form for a reinforced concrete floor, the leg 30 is firmly adsorbed to the form so that a sense of stability is obtained. Get better. However, it is not always necessary to fit a magnet such as a magnet plate in the leg portion 30.
Here, the disk-like member 33 is firmly fixed to the male screw with knob 36 so that the angle formed with the male screw with knob 36 does not change. However, this is not always necessary. The angle formed with the shaped member 33 can be made variable. Thereby, even if the floor surface is curved, the floor surface can be firmly captured by the legs 30.

The sliding member 20 is provided with a vertical through-hole 25 that passes through the central portion 11 of the cut-out flat plate member 10, and the through-hole 25 has a hollow first shape with a thread 21 a carved on the outer surface. One cylindrical member 21 is fitted. As shown in FIG. 2, a window 27 for reading the scale 13 is provided on the side surface corresponding to the side surface of the flat plate member 10 with the scale 13. And the mark which shows the position which the 1st rod 15 moves up and down is attached | subjected to the side surface in which the window 27 was formed.
Therefore, even when the reference point is marked on the floor surface at a level different from the floor surface where the transit is installed, if the first rod 15 can be visually recognized in the original direction from the transit, At the position, the first rod 15 can be pushed down to mark the reference position.
Here, a male screw 36 with a knob is screwed onto the side surfaces of the fitting member 31 and the sliding member 20. When the knob is turned, the fitting member 31 and the sliding member 20 are fixed to the side surface of the planar member 10.
As a result, the leg 30 is firmly fixed and the first rod 15 does not move, so that accurate inking can be performed.

FIG. 5 is a cross-sectional view showing a state in which the first rod body is fitted through the first cylindrical member.
As shown in FIG. 5, the first cylindrical member 21 is a hollow cylinder, is fitted into a through hole 25 that vertically penetrates the sliding member 20 and the flat plate member 10, and is screwed into a male screw 25 a carved on the outer surface. The mating nuts 28 are firmly fixed to the top surface 20a and the bottom surface 20b of the sliding member 20, respectively, so that the verticality is maintained.
The first cylindrical member 21 is fitted with an elongated cylindrical first rod 15 having a length of 15 to 20 cm.
In the first rod 15, a light emitting member (corresponding to “light emitting means” of the present invention; the same applies hereinafter) in which a light emitting agent such as a luminous paint, a fluorescent paint, and a daylight paint is applied or contained in the upper part 15 a is joined. A writing instrument such as a ballpoint pen or a felt pen (corresponding to the “recording means” of the present invention) is joined to the lower portion 15b.
Here, the length of the first rod does not have to be limited to 15 cm to 20 cm, but if it is too long, the inking aid 1 may fall over and the balance with the string spring 24 cannot be maintained. Adjustment is necessary.
A string winding spring 24 is wound above the first rod 15, one end of the string winding spring 24 is fixed above the first rod 15, and the other end is an upper opening of the first tubular member 21. It touches the end.
Although the gravity of the first rod 15 is applied to the string spring 24, the string spring 24 is stationary at a position away from the floor surface by the force of the string spring 24. Accordingly, when the upper portion 15a of the first rod 15 is pushed down with a finger, the first rod 15 moves downward, and ink can be drawn with the writing tool on the lower portion 15b. Then, when the finger is released, the cloth spring 24 returns to the upper original position by the energizing force of the string spring 24.
Further, a screw 21 c that prevents the movement of the first rod 15 is screwed onto the upper portion of the first cylindrical member 21.
Thus, since the 1st rod 15 has predetermined length, it is lower than the floor surface where the transit was installed, such as a floor surface of a water field, a floor surface with a large level difference such as a stair landing, etc. Even if it is impossible to see the position where the first bar 15 is to be seen, if the upper part 15a of the first bar 15 can be visually recognized, the first bar 15 can be pushed down at that position so that ink can be drawn.

FIG. 6 is a diagram illustrating, as an example, a state in which a lighting fixture that illuminates the upper end of the first rod is attached to the first tubular member.
The lighting tool 38 shown in FIG. 6 can be attached to the first tubular member 21 by being sandwiched between clips 39. The lamp 38a is directed upward to illuminate the upper portion 15a of the first rod 15 and indoors. In this example, even if it is dark, it can be easily visually recognized from the transit.
However, if the upper part 15a of the 1st rod 15 is comprised by the member which applied luminescent agents, such as a luminescent paint, a fluorescent paint, and a livestock paint, or the member containing them, the lighting fixture 38 is not necessarily required.
In addition, the thing which makes LED light-emit with the battery is small and the lighting fixture 38 is preferable.

Next, a usage example of the summing-out assisting tool of the present embodiment will be described.
FIGS. 7A and 7B are diagrams showing a case in which a sumi ink is applied to a floor including a bathroom where the floor level is low, FIG. 7A is a plan view of the floor, and FIG. 7B is a cross-sectional view of the floor. FIG.
As shown in FIG. 7, there is a bathroom floor surface B lower than the floor surface where the transit T is arranged in the floor. Can see, so you can get ink, but you can't see the front. Therefore, the inking aid 1 is arranged in front of the bathroom floor B, and the sliding member 20 is moved and adjusted so that the upper portion 15a of the first rod 15 is on the line. When the alignment is completed, the upper part 15a of the first bar 15 is pushed with a finger, and the ink is drawn on the bathroom floor B with the lower part 15b of the first bar 15.
FIG. 8 is a diagram showing a case where return ink is applied to the stair landing.
As shown in FIG. 8, when the transit T is installed on the downstairs, the front of the landing S can be seen, but the back of the landing S cannot be seen. Therefore, by placing the inking aid 1 in the back of the landing S and visually recognizing the upper portion 15a of the first rod 15, the inking can be performed.

[Second Embodiment]
Compared with the first embodiment, the second embodiment includes second cylindrical members on both sides of the flat plate member, and can confirm that the first rod moves on a predetermined line. The difference is that the distance by which the first rod arranged at a position visible from the transit is moved to the position to be inked is calculated and the ink can be inked at that position. However, since the other points are common, the description will be centered on the differences while avoiding repeated explanation.

9-12 is a figure which shows the inking aid of 2nd Embodiment, FIG. 9 is a top view, FIG. 10 is a front view, FIG. 11 is a rear view, FIG. 12 is a bottom view.
The inking aid 2 shown in FIGS. 9 to 12 is, like the inking aid 1 of the first embodiment, an elongated flat plate member 10 having a length of about 50 cm with a central portion 11 cut out in the longitudinal direction. A sliding member 20 having a rectangular hollow cross section, fitted on the flat plate member 10 and sliding in the longitudinal direction, and a length of about 5 cm; A leg 30 that can be adjusted in height and a bubble ridge 35 attached to the sliding member 20 are provided to determine whether or not the sliding surface of the sliding member 20 is horizontal. The sliding member 20 is provided with a first cylindrical member 21 penetrating vertically. The first cylindrical member 21 is wound with a string spring 24 and has a length of 15 cm to 20 cm. One rod 15 is inserted. In addition, the upper part 15a of the 1st rod 15 is comprised by the member containing a luminescent agent, and the writing instrument is attached to the lower part 15b. Moreover, the lighting tool 38 which makes LED light-emit with a battery is attached to the 1st cylindrical member 21 so that attachment or detachment is possible, and it can be visually recognized from a transit even if it is dimly lit indoors.

In addition to the above, in the inking aid 2 of the present embodiment, the second cylindrical member 22 is fixed in parallel to the first cylindrical member 21 on each end face of the fitting member 31 on both sides of the flat plate member 10. . The second cylindrical member 22 is fitted with a second rod 16 made of an elongated cylinder having a length of 10 cm to 15 cm. A string-wound spring 24 is wound above the second rod body 16, one end of the string-wound spring 24 is fixed to the upper portion of the second rod body 16, and the other end is an upper opening end of the second cylindrical member 22. It is in contact.
The string spring 24 is urged upward, but balances with the gravity of the second rod body 16 and is stationary at a position where the tip is separated from the floor surface.
Since the second rod body 16 is fixed on the line of the central portion 11 of the flat plate member 10 where the first rod body 15 moves, the second rod body 16 is pushed down when the upper portion of the second rod body 16 is pushed down with a finger. It can be confirmed that the position touched by the tip is on the line of ink. Therefore, it is easy to install the inking aid 2 so that the second rod bodies 16 on both sides are on the line of the parent ink. If the summing-out assisting tool 2 is arranged on the ink line in this way, when the first rod 15 is viewed from the transit, a temporary reference that allows the first rod 15 to be visually recognized as a line through which the original reference position can be seen. The distance from the temporary reference position to the original reference position can be obtained from the angle formed by the line that predicts the position.

As shown in FIG. 10, the sliding member 20 is provided with a window 27 through which the scale 13 can be read on the side surface corresponding to the side surface of the flat plate member 10 with the scale 13. And the mark which shows the position which the 1st rod 15 moves up and down is attached | subjected to the side surface in which the window 27 was formed.
Accordingly, when the reinforcing bar or the like becomes an obstacle and the reference position cannot be seen from the transit, the position where the first stick 15 can be seen by shifting the inking aid 2 is set as a temporary reference position. Then, the scale 13 at the temporary reference position is read from the window 27 provided on the sliding member 20.
Then, while measuring the angle Θ between the line foreseeing the original reference position and the line foreseeing the temporary reference position by transit, the distance L from the original reference position to the installation position of the transit is obtained from a drawing or the like. By calculating the distance X from the temporary reference position to the original reference position.
Then, the first rod 15 is moved to the right or left by X from the numerical value read from the window 27 on the side surface of the sliding member 20, and the first reference rod 15 is pushed down to mark the original reference position on the floor surface. To do.
Here, the calculation of LtanΘ is performed, for example, by changing the angle Θ from 0 degrees to 1 degree to 3 degrees by 1 minute (about 0.0167 degrees) every 1 meter from 10 meters to about 50 meters. If the correspondence table of LtanΘ at this time is prepared, the distance X can be obtained immediately by obtaining the angle Θ and the distance L.

Next, a usage example of the summing-out assisting tool of the present embodiment will be described.
FIG. 13 is a diagram illustrating an example in which the ink is applied when there is an obstacle on the way when viewed from the transit.
As shown in FIG. 13, when viewed from the transit T, if there is a wall or column arrangement in the middle and the original level cannot be seen, the second bar 16 of the inking aid 2 is pushed down, Arrange them so that they are on the lines of the ink marks X and Y. Then, the first rod 15 is moved to a position that can be seen from the transit T (temporary reference position). At that time, the scale is read from the window 27. Next, an angle shift Θ when the first rod 15 is viewed from the transit T is measured, and a distance L from the transit T to the reference position is obtained from the drawing. Then, the deviation from the original reference position is obtained from the correspondence table from L and Θ, the first rod 15 is moved by the amount of the deviation, the first rod 15 is pushed down at that position, and the original reference position Ink out.
In FIG. 13, for example, when L is 30 m and Θ1 is 10 minutes, the first rod 15 is shifted to the left by 29.1 mm, and when Θ2 is 1 degree 15 minutes, the first rod 15 is 56.7 mm. Shift to the right to mark the original reference position.

[Third Embodiment]
In the third embodiment, even if a predetermined parent ink or child ink is not drawn at the position where the ink-out auxiliary tool is installed, the ink can be put out at the correct position by moving the first rod. Furthermore, the point which equips the bottom face of a sliding member with the 3rd rod for positioning differs from 1st Embodiment and 2nd Embodiment. However, since the other points are common, in order to avoid redundant description, the difference will be described based on the inking aid described in the first embodiment.
14-17 is a figure which shows the inking aid of 3rd Embodiment, FIG. 14 is a bottom view, FIG. 15 is the bottom view which expand | deployed the 3rd rod, FIG. 16 is the 3rd rod. Expanded plan view,
FIG. 17 is a side view of the developed third rod.
As shown in FIGS. 14 to 17, the inking aid 3 of the third embodiment has a length from the fixing position of the first tubular member 21 on the bottom surface of the sliding member 20 to the end of the fitting member 31. A linear third rod body 17 is pivotally supported on the sliding member 20 so as to be rotatable. The rotation shaft 18 is located side by side with the first cylindrical member 21, and in the vicinity thereof, a limiting member 19 that restricts the angle at which the third rod body 17 rotates to 90 degrees is provided. Therefore, when the third rod body 17 is rotated, the third rod body 17 stops at a position orthogonal to the direction in which the first rod body 15 moves. In that case, when the first rod 15 is viewed from the transit, if the third rod 17 is seen on the same vertical line as the first rod 15 as shown in FIG. It can be confirmed that it is arranged.
Here, although the inking aid 3 of the present embodiment is shown for the inking aid 1 of the first embodiment with the third rod 17 installed, the inking aid 2 of the second embodiment A third rod 17 may be installed.

18 and 19 are diagrams illustrating a method for confirming the arrangement position of the inking aid according to the third embodiment, and FIG. 18 is a diagram illustrating the relationship between the arrangement position of the inking aid and the third rod body. FIG. 19 is a diagram in which the third rod body is viewed from the transit.
As shown in FIG. 18, even when the first rod 15 is arranged at a position where it can be seen from the transit, the case where the inking aid 3 is arranged at the correct position and the case where it is arranged at a slightly bent position are shown. The tip position of the third rod 17 is different.
As shown in FIG. 19, when the first rod 15 and the third rod 17 are viewed from the transit telephoto lens R, the first rod 15 is disposed at a position overlapping the vertical line V at the center of the telephoto lens R. However, when the third rod 17 is on the right side of the vertical line V, the inking tool 3 is slightly rotated counterclockwise toward the transit, and the third rod 17 is on the left side of the vertical line V. If the inking aid 3 is rotated to the right slightly toward the transit so that it overlaps the vertical line V, the inking aid 3 will be in the correct position even if no parent ink or child ink is drawn. Can be arranged.

It can be used for surveying of road construction and civil engineering as well as inking of building construction and interior construction in building construction.
