Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a positioning ruler for positioning a member to be installed at a position away from a reference position.

The reinforced concrete form is generally built in the order of pillars, outer wall outer side, beams, outer wall inner side and inner wall, slabs, stairs and other parts in this order.
However, it is necessary to install crosspieces etc. at a location apart from the slab form or beam form to define the level difference at locations where there are level differences such as verandas and entrances and the like. Fix to reinforcements etc. to withstand the pressure when installed. At that time, it is necessary to support the crosspieces to be installed by hand, float from the existing formwork, measure the height and separation distance with a balance, etc., and use the separator etc. I will win. As a result, at the time of the inspection at which the concrete is cast, a deviation in size is found, and a great deal of labor such as sharpening of the concrete is wasted.
Further, even in the case of measuring only the height and width, if the length of the ruler is relatively short, the dimensional deviation tends to occur.
Therefore, a method of positioning an object at a position separated by a predetermined distance in the horizontal direction and in the vertical direction has been proposed.
For example, in order to properly fix the pedestal on the pedestal, a reference plate is drawn by a strip-shaped positioning jig provided with a longitudinally extending elongated hole and a notch for lowering the hanging thread, and having a scale. The positioning method which measures the height from the floor surface and the distance from a reference line, and arranges a pedestal in a position as a design figure is disclosed (refer to patent documents 1).
In addition, when assembling the precut foundation or column, the temporary foundation support plate is attached to the side end face because the foundation of the foundation can not be installed at the designed location unless the anchor bolt is properly arranged at the designed position. There is disclosed a temporary material ruler in which a plurality of mounting protrusions for forming a plurality of mounting projections can be protruded from a flange of a mold (see Patent Document 2).
On the other hand, even in the simple work of drawing ink on a wall, it is necessary to set scales on at least two places, read the scale with a level machine or transit, and draw an ink thread while setting up an ink needle. Since it is a manual operation, it is possible to stably and easily attach it to a wall to enable one-person operation, and a scale capable of reading a scale not only from the front but also from the side is disclosed. Reference 3).

However, the method described in Patent Document 1 is a method that can be applied when a reference line is drawn in advance on a floor surface and the height and distance therefrom are specified, and the method described in Patent Document 2 is a ruler. Since the shape of is specified, it is necessary to create a ruler each time according to the symmetry. Further, the method described in Patent Document 3 is limited to measurement in the height direction.
In view of the above-described circumstances, the present invention can measure the separation distance either in the horizontal direction or the vertical direction from the reference line by one person, or can measure the separation distances in both the horizontal direction and the vertical direction simultaneously by one person. An object of the present invention is to provide a positioning ruler which enables one person to construct the positioning of members disposed there.

The positioning ruler of the present invention extends in a direction perpendicular to the first rod, and a first rod of a predetermined length marked with a scale starting at one end or the other end and ending at the other end or the one end. And a second member longer than the first member rotatably fixed at the same position as the first member, and sliding toward the end of the first rod A first sliding member that is freely externally fitted, and the first member and the second member each have a scale whose starting point is an end on the side fixed to the first sliding member The first member has a U-shaped groove formed on the side surface, and the second member freely pivots between a position overlapping with the first rod and a position fitting into the groove. It is characterized by
In this way, the first member and the second member with the scale orthogonal to the rod are fixed to the first sliding member that slides the rod with the scale in both directions, and the second member is the second Since it is longer than one member and rotates, using either the first member or the second member allows the separation distance up to several tens of centimeters to be measured by one person simultaneously with the height. .
The first rod body is a hollow member having a predetermined cross section, has the same cross section as the first rod body, and has a protrusion formed at one end and joined to the other end, at least the one end The at least one second rod of a predetermined length having a scale that starts at the other end and ends at the other end, the one second rod or the second rods joined together. The height and length of several meters can be measured by one person by increasing the number of the second rods, because the first rods can be combined and integrated.
In that case, the holding portion of the pin which is biased by a spring and freely moved up and down is formed on the side surface, and the second sliding member which is externally fitted and slidable to the first rod or the second rod is If provided, any part of the first rod body or the second rod body can be fixed to the formwork or the like, and the measurement can be facilitated by one person alone.
A third sliding member having a window for freely reading the scale of the first rod or the second rod, which is slidably fitted on the first rod or the second rod. Is convenient for measuring the distance from the predetermined reference point to the first sliding member.
And if the said 1st sliding member, said 2nd sliding member, and said 3rd sliding member each are equipped with the suppression part which suppresses a slide, accurate measurement can be performed.

  By using the positioning ruler according to the present invention, it is possible to measure either the horizontal or vertical separation distance from the reference line by one person, and also to measure the horizontal and vertical separation distances simultaneously by one person. Positioning can be done alone.

First Embodiment
FIG. 1 is a view showing the positioning ruler of the first embodiment, and FIG. 1 (a) is a front view, FIG. 1 (b) is a rear view, FIG. 1 (c) is a top view, FIG. ) Is a bottom view.
The positioning ruler 1 of the first embodiment shown in FIG. 1 includes a first rod 5, a first sliding member 10, and a second sliding member 20.
The first rod 5 is not shown but has a rectangular or square hollow cross section and is an aluminum member 100 cm in length, with one end 5 a being zero and the other end 5 b on the top and bottom surfaces. A scale 8 of 1000 mm is marked or a scale 8 of 1000 mm at one end 5 a and zero at the other end 5 b.
The first sliding member 10 and the second sliding member 20 are aluminum members having a rectangular or square cross section and having a length of about 5 to 6 cm, and can slide on the first rod 5 It is externally fitted. Then, a screw 40 with a knob (corresponding to the "restraining portion" of the present invention) 40 is provided on the front, and if the screw 40 with a knob is tightened, the sliding is suppressed, and if loosened, it can freely slide. It is configured.
The first sliding member 10 is pivotally supported at the same position as a first member 11 having a length of 10 cm and a second member 12 having a length of 20 to 30 cm, which extend in a direction perpendicular to the first rod 5. The first member 11 is fixed so as not to move at a right angle to the first rod 5, and the second member 12 is pivotally supported. The first member 11 has a supported end 14 at zero and the other end 100 mm, and the second member 12 has a supported end 14 at zero and the other end 200 to 300 mm. Is noted.
Also, the first member 11 is formed with a U-shaped groove (not shown) 13 in the longitudinal direction of the side surface, and the second member 12 is pivoted with the fixed end fitted in the groove 13 It is supported.
Therefore, the second member 12 can be moved from the position where the longitudinal direction coincides with the first rod 5 and the longitudinal direction coincides with the first member 11 from the position where it closely overlaps, and the position where the first member fits snugly in the groove 13 .
That is, the height can be measured by the first rod 5, and the horizontal separation distance can be measured by the first member 11 or the second member 12.
In that case, the first member 11 is used to measure the distance up to 10 cm, and the second member 12 is used when the distance is greater than that.
The second sliding member 20 is formed on the side with the holding portion 21 of the pin 22 which is biased by the spring 23 and freely moved up and down. Therefore, the holding portion 21 is applied to the mold and the tip is sharpened. If the pin 22 is pressed in, the tip end is inserted into the mold or the like, and the positioning ruler 1 can be fixed to the mold or the like.

It is formed of a manufactured member. Then, on the front face of the first sliding member 10, the first member 11 having a length of 10 cm is pivotally supported in the direction orthogonal to the first rod 5, and the second member 12 having a length of 20 to 30 cm is It is pivotally supported in the direction overlapping with the first rod body 5. Further, a scale 8 is marked in which the end 14 of each of the first member 11 and the second member 12 on the pivotally supported side is the start point and the other end is the end point. A thumb screw 40 is provided at the front center portion to prevent the first sliding member 10 from sliding the first rod 5 freely. And since magnet sheet 15 is stuck on the side (the side by which the 1st member and the 2nd member are supported pivotally) and back of the 1st sliding member 10, it joins to a reinforcing bar and a steel aggregate, and positioning The ruler 1 can be fixed.
The first member 11 is pivotally supported by the first sliding member 10 so as not to move, but a groove 13 of a size into which the second member 12 is fitted is provided on the upper surface, and the second member 12 is Since it is pivotally supported by the same shaft so as to be able to turn in the direction of arrow A, it freely turns between the position overlapping with the first rod 5 and the position fitting into the groove 13 and overlapping with the first member 11.
Therefore, when the separation distance is short, the scale 8 of the first member 11 may be used, but when the separation distance is longer than the first member 11, the second member 12 is rotated to the position where the second member 12 overlaps the first member 11. The scale 8 of the second member 12 can be moved to correspond.
That is, since the short first member 11 is firmly fixed to the first sliding member 10 with a screw, the horizontal distance can be correctly measured, and the long second member 12 is the first member. Since it is supported by 11, it is possible to correctly measure a longer horizontal distance than that.

The reinforced concrete form is generally built in the order of pillars, outer wall outer side, beams, outer wall inner side and inner wall, slabs, stairs and other parts in this order.
However, it is necessary to install crosspieces etc. at a location apart from the slab form or beam form to define the level difference at locations where there are level differences such as verandas and entrances and the like. Fix to reinforcements etc. to withstand the pressure when installed. At that time, it is necessary to support the crosspieces to be installed by hand, float from the existing formwork, measure the height and separation distance with a balance, etc., and use the separator etc. I will win. As a result, at the time of the inspection at which the concrete is cast, a deviation in size is found, and a great deal of labor such as sharpening of the concrete is wasted.
Further, even in the case of measuring only the height and width, if the length of the ruler is relatively short, the dimensional deviation tends to occur.
Therefore, a method of positioning an object at a position separated by a predetermined distance in the horizontal direction and in the vertical direction has been proposed.
For example, in order to properly fix the pedestal on the pedestal, a reference plate is drawn by a strip-shaped positioning jig provided with a longitudinally extending elongated hole and a notch for lowering the hanging thread, and having a scale. The positioning method which measures the height from the floor surface and the distance from a reference line, and arranges a pedestal in a position as a design figure is disclosed (refer to patent documents 1).
In addition, when assembling the precut foundation or column, the temporary foundation support plate is attached to the side end face because the foundation of the foundation can not be installed at the designed location unless the anchor bolt is properly arranged at the designed position. There is disclosed a temporary material ruler in which a plurality of mounting protrusions for forming a plurality of mounting projections can be protruded from a flange of a mold (see Patent Document 2).
On the other hand, even in the simple work of drawing ink on a wall, it is necessary to set scales on at least two places, read the scale with a level machine or transit, and draw an ink thread while setting up an ink needle. Since it is a manual operation, it is possible to stably and easily attach it to a wall to enable one-person operation, and a scale capable of reading a scale not only from the front but also from the side is disclosed. Reference 3).
In addition, the applicant has a long third rod-like member which is slidable by being fitted to the hollow portions of both the hollow long first rod-like member and the hollow second short rod-like member. The member has a scale with one end as a reference point and a scale with the other end as a reference point on the outer surface from one end to the other, and the third rod-like member is joined to the first rod-like member from one end The outer surface up to the end of the mark has a scale with one end as a reference point, and a scale with a predetermined position from the other end as a reference point so as to be continuous with the scale of the first rod member. The 2 bar-like member discloses a scale in which a window for reading the scale of the third bar-like member is formed (Patent Document 4).
