Description

[Technical Field]

[0001] The present disclosure relates to a measurement auxiliary jig. [Background technology]

[0002] Patent Document 1 discloses a concrete foundation. Patent Document 2 discloses a foundation formwork used in forming the foundation. The foundation is formed by concrete poured into the foundation formwork and hardening. The foundation and the foundation formwork have a first portion and a second portion intersecting the first portion.

[0003] The worker measures the dimensions of the foundation or foundation formwork when the foundation is completed or the foundation formwork is assembled. More specifically, the worker sets a first center line, a second center line, and a reference point for the foundation or foundation formwork. The first center line is a center line that extends in the direction in which the first section extends and is located at the center of the width of the first section. The second center line is a center line that extends in the direction in which the second section extends and is located at the center of the width of the second section. The reference point is the intersection of the first center line and the second center line. The worker uses a measuring tool to measure the distance from the reference point set on the foundation or foundation formwork to a specified position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-15534 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-90049 Summary of the Invention [Problem to be solved by the invention]

[0005] The worker sets the first centerline, second centerline, and reference point by measuring the dimensions of the first and second parts, so it is necessary to measure the dimensions of the first and second parts every time the reference point changes position. In addition, the measurement work requires two workers: one to hold one end of the measuring member at the reference point, and one to check the numerical value of the measuring member at the specified position. [Means for solving the problem]

[0006] (1) A measurement auxiliary jig that solves the above problem is a measurement auxiliary jig that assists in measuring an object to be measured, which has a first portion and a second portion that intersects with the first portion, by setting a reference point where a first centerline of the first portion intersects with a second centerline of the second portion, and measuring the distance from the reference point to a predetermined position using a measuring member, and is provided with a first mounting member that is attached to the first portion, a second mounting member that is attached to the second portion, and a connecting member that connects the first mounting member and the second mounting member, wherein the first mounting member and the second mounting member each have a clamping portion that clamps the object to be measured, and an axis portion that extends in a direction perpendicular to the clamping direction of the clamping portion and is located at the center of the clamping direction, and the connecting member has an mounting portion to which the measuring member is attached, and at least one of the two axis portions is rotatable around the mounting portion.

[0007] According to this configuration, the shank extends in a direction perpendicular to the clamping direction and is centered in the clamping direction. Therefore, when the clamping portion of the first mounting member clamps a first portion of the measurement object, the shank overlaps the first center line. When the clamping portion of the second mounting member clamps a second portion of the measurement object, the shank overlaps the second center line.

[0008] At least one of the two shafts is rotatable around the mounting part. Therefore, regardless of the angle formed by the two shafts, the mounting part overlaps the intersection of a first imaginary line extending from the shaft of the first mounting member and a second imaginary line extending from the shaft of the second mounting member. Therefore, the mounting part overlaps the reference point where the first and second center lines intersect.

[0009] This allows the worker to easily set a reference point for the measurement object simply by attaching the first and second attachment members to the measurement object and connecting the first and second attachment members via the connecting member. Then, by attaching the measuring member to the attachment part, the worker can measure the distance from the reference point to a predetermined position by himself, even without another worker holding down one end of the measuring member at the reference point. This improves the workability of the measurement work.

[0010] (2) In the measurement auxiliary jig of (1) above, the connecting member has a rail that extends in a circular shape centered on the mounting portion, and the shaft portion has a slider that is slidable along the rail. According to this configuration, the worker can adjust the angle formed by the two shafts by sliding the slider of the shafts along the rail.

[0011] (3) In the measurement auxiliary jig described above in (2), the connecting member has an inner ring and an outer ring located on the outer periphery of the inner ring, and the rail is a gap provided between the outer surface of the inner ring and the inner surface of the outer ring.

[0012] With this configuration, for example, compared to when the groove provided on the upper surface of the plate-shaped member is a rail, members that protrude upward from the object to be measured, such as anchor bolts that protrude from the upper surface of the foundation, are less likely to interfere with the connecting member.

[0013] (4) In the measurement auxiliary jig described above in (1), the connecting member is fixed to the shaft portion of one of the first mounting member and the second mounting member, and the other shaft portion has a grip portion that engages with the mounting member.

[0014] This configuration simplifies the configuration of the measurement auxiliary jig. In addition, because the connecting member is integrated with one of the first mounting member and the second mounting member, the number of parts of the measurement auxiliary jig can be reduced.

[0015] (5) In the auxiliary measuring jig of (4) above, the shaft portion is slidable in the axial direction of the shaft portion relative to the clamp portion. According to this configuration, after attaching the first attachment member and the second attachment member to the measurement object, the operator can slide the shaft portion to lock the grip portion onto the attachment portions.

[0016] (6) In the auxiliary measurement tool of any one of (1) to (5) above, the clamping portion has two clamping portions that clamp the measurement object, and the distance between the two clamping portions is changeable. According to this configuration, the distance between the two clipping portions can be changed, so that it is possible to accommodate a variety of measurement targets with different widths.

[0017] (7) In the measurement auxiliary jig described above in (6), the clamping portion has a base portion and a connecting member that connects the base portion and the clamping portion, and the connecting member includes a spring. With this configuration, the two clamping parts are biased toward each other by the compression force of the spring, so that the clamping part can stably clamp the measurement object.

[0018] (8) In the measurement auxiliary jig of (6) above, the clamp portion has a base and a connecting member connecting the base and the clamping portion, the connecting member including a spring, the base is provided with a buckle that can rotate around a rotation axis extending parallel to the axial direction of the shaft portion, and a first end of the connecting member is connected to the buckle.

[0019] With this configuration, the two clamping parts are biased toward each other by the compression force of the spring, so that the clamping part can stably clamp the measurement object. A buckle is also provided on the base. A first end of the connecting member is connected to the buckle. Therefore, when the buckle is rotated so as to approach the shaft, the spring of the connecting member connected to the buckle is stretched, increasing the force that urges the two clamping portions toward each other. Therefore, the clamping portion can more stably clamp the measurement object.

[0020] (9) In the measurement auxiliary jig described above in (8), the clamping portion is provided with a plurality of hooks in the clamping direction for hooking the second end of the connecting member. With this configuration, by changing the hook that hooks the connecting member depending on the width of the first or second portion, the elongation rate of the spring can be reduced even when the width of the first or second portion is large. Therefore, a stronger spring with a larger spring constant can be used as the spring for the connecting member, and the clamp portion is less likely to slip even when the measuring member is attached to the mounting portion and pulled for measurement.

[0021] (10) In any one of the measurement auxiliary jigs (7) to (9) above, the clamping portion has a main body portion that follows the side surface of the object to be measured, an extension portion that extends from the lower end of the main body portion toward the base portion, and a magnet provided on the upper surface of the extension portion.

[0022] According to this configuration, when the measurement object is a foundation formwork, the mounting member can be properly attached to the foundation formwork. Specifically, the foundation formwork has two side panels and two flanges extending away from each other from the upper ends of the two side panels. According to the above configuration, the clamping unit has an extension extending from the lower end of the main body toward the base and a magnet provided on the upper surface of the extension. Therefore, when the clamp unit clamps the foundation formwork, the extension is located below the flange. The magnet provided on the upper surface of the extension attaches to the lower surface of the flange by magnetic force, causing the measurement auxiliary jig to float above the upper surface of the foundation formwork. Therefore, components protruding upward from the upper surface of the foundation formwork are less likely to interfere with the measurement auxiliary jig, allowing the mounting member to be properly attached to the foundation formwork. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0025] [First embodiment] 1 and 2, a measurement auxiliary jig 10 according to a first embodiment will be described. The measurement auxiliary jig 10 is a jig for assisting a worker in measuring the dimensions of an object to be measured using a measuring member 100. The object to be measured in this embodiment is a foundation 110. The measuring member 100 is, for example, a steel tape.

[0026] <Basics> As shown in Fig. 1, the base 110 has a first rising portion 111, which is a first portion, and a second rising portion 112, which is a second portion. The second rising portion 112 intersects with the first rising portion 111. In this embodiment, one end of the first rising portion 111 intersects with one end of the second rising portion 112. Therefore, an intersection 110a between the first rising portion 111 and the second rising portion 112 forms a corner.

[0027] In order to measure the dimensions of the foundation 110, a first center line N1 is set in the first rising portion 111. The first center line N1 extends in the direction in which the first rising portion 111 extends. The first center line N1 is located at the center of the width direction of the first rising portion 111. The width direction of the first rising portion 111 is a horizontal direction that is perpendicular to the direction in which the first rising portion 111 extends.

[0028] A second center line N2 is set in the second rising portion 112. The second center line N2 extends in the direction in which the second rising portion 112 extends. The second center line N2 is located at the center of the width direction of the second rising portion 112. The width direction of the second rising portion 112 is a horizontal direction that is perpendicular to the direction in which the second rising portion 112 extends.

[0029] A reference point P is set on the foundation 110. The reference point P is the intersection of the first center line N1 and the second center line N2. The worker measures the dimensions of the foundation 110 by measuring the distance from the reference point P to a predetermined position using the measuring member 100. The predetermined position is, for example, another reference point.

[0030] <Auxiliary measuring fixture> 1 and 2, the measurement auxiliary jig 10 includes a first mounting member 12a, a second mounting member 12b, and a connecting member 13. The first mounting member 12a is attached to the first rising portion 111. The second mounting member 12b is attached to the second rising portion 112. The connecting member 13 connects the first mounting member 12a and the second mounting member 12b.

[0031] The first mounting member 12a and the second mounting member 12b have the same configuration. Each of the first mounting member 12a and the second mounting member 12b has a clamp portion 21 and a shaft portion 22. The clamp portion 21 clamps the foundation 110. The clamp portion 21 of the first mounting member 12a clamps the first raised portion 111. The clamp portion 21 of the second mounting member 12b clamps the second raised portion 112. The clamp portion 21 has two clamp plates 23 and a connection plate 24. The two clamp plates 23 sandwich the first raised portion 111 or the second raised portion 112 in the width direction. The connection plate 24 connects the two clamp plates 23. In the following description, the clamp portion 21 of the first mounting member 12a may be referred to as the first clamp portion 21a, and the clamp portion 21 of the second mounting member 12b may be referred to as the second clamp portion 21b.

[0032] The shaft portion 22 extends in a direction perpendicular to the clamping direction of the clamp portion 21. The shaft portion 22 is located at the center in the clamping direction. The shaft portion 22 in the first embodiment is fixed to the upper surface of the connection plate 24. A slider 25 is provided at one end of the shaft portion 22. The slider 25 is arc-shaped and fits along the circular rail 13a, which will be described later. In the following description, the shaft portion 22 of the first mounting member 12a may be referred to as the first shaft portion 22a, and the shaft portion 22 of the second mounting member 12b may be referred to as the second shaft portion 22b.

[0033] The coupling member 13 of the first embodiment has a circular inner circumferential ring 31, a circular outer circumferential ring 32, a ring connecting portion 33, and an attachment portion . The inner diameter of the outer ring 32 is larger than the outer diameter of the inner ring 31. The outer ring 32 is located on the outer periphery of the inner ring 31. The center of the outer ring 32 is the same as the center of the inner ring 31. A gap is provided between the outer peripheral surface of the inner ring 31 and the inner peripheral surface of the outer ring 32, forming a rail 13a.

[0034] The ring connection portion 33 connects the inner ring 31 and the outer ring 32. The ring connection portion 33 passes through the centers of the inner ring 31 and the outer ring 32 and extends in the radial direction of the inner ring 31 and the outer ring 32.

[0035] The measuring member 100 is attached to the attachment portion 34. The attachment portion 34 is provided on the upper surface of the ring connecting portion 33. The attachment portion 34 is located at the center of the inner ring 31 and the outer ring 32. Therefore, the rail 13a extends in a circular shape with the attachment portion 34 as the center.

[0036] The slider 25 is slidable along the rail 13a. Therefore, the shaft portion 22 is rotatable around the mounting portion 34. In the first embodiment, both the first shaft portion 22a and the second shaft portion 22b are rotatable around the mounting portion 34.

[0037] [Operation of the first embodiment] The operation of the first embodiment will be described together with a method of using the measurement auxiliary jig 10 of the first embodiment.

[0038] The worker engages the sliders 25 of the first shaft portion 22a and the second shaft portion 22b with the rails 13a of the connecting member 13. As a result, the first mounting member 12a and the second mounting member 12b are connected by the connecting member 13. After that, the worker clamps the first raised portion 111 with the first clamp portion 21a and clamps the second raised portion 112 with the second clamp portion 21b. As a result, the first mounting member 12a is attached to the first raised portion 111 and the second mounting member 12b is attached to the second raised portion 112. Therefore, the measurement auxiliary jig 10 is attached to the foundation 110.

[0039] The method of attaching the measurement auxiliary jig 10 to the foundation 110 is not limited to the above method. After placing the connecting member 13 at the intersection 110a of the foundation 110, the worker may attach the first attachment member 12a to the first rising portion 111 and the second attachment member 12b to the second rising portion 112.

[0040] The shaft 22 extends in a direction perpendicular to the clamping direction of the clamp portion 21 and is located at the center in the clamping direction. Therefore, when the first clamp portion 21a clamps the first rising portion 111, the first shaft 22a overlaps the first center line N1 of the first rising portion 111. When the second clamp portion 21b clamps the second rising portion 112, the second shaft 22b overlaps the second center line N2 of the second rising portion 112.

[0041] The first shaft portion 22a and the second shaft portion 22b are each rotatable about the mounting portion 34. Therefore, regardless of the angle formed by the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 overlaps the intersection Q of a first imaginary straight line L1 extending from the first shaft portion 22a and a second imaginary straight line L2 extending from the second shaft portion 22b. Therefore, the mounting portion 34 overlaps the reference point P where the first center line N1 and the second center line N2 intersect.

[0042] This allows the worker to easily set the reference point P with respect to the foundation 110 simply by attaching the first mounting member 12a and the second mounting member 12b to the foundation 110 and connecting the first mounting member 12a and the second mounting member 12b via the connecting member 13. Then, by attaching the measuring member 100 to the mounting portion 34, the worker can perform the measurement work alone, without the need for another worker to hold down one end of the measuring member 100 at the reference point P. This improves the workability of the measurement work.

[0043] [Effects of the first embodiment] The effects of the first embodiment will be described. (1-1) The measurement auxiliary jig 10 includes a first mounting member 12a, a second mounting member 12b, and a connecting member 13. The first mounting member 12a is attached to a first rising portion 111 of the foundation 110. The second mounting member 12b is attached to a second rising portion 112 of the foundation 110. The connecting member 13 connects the first mounting member 12a and the second mounting member 12b. The first mounting member 12a and the second mounting member 12b each include a clamp portion 21 and a shaft portion 22. The clamp portion 21 clamps the foundation 110. The shaft portion 22 extends in a direction perpendicular to the clamping direction of the clamp portion 21 and is located at the center of the clamping direction. The connecting member 13 includes an attachment portion 34 to which the measurement member 100 is attached. The shaft portion 22 is rotatable around the attachment portion 34.

[0044] According to this configuration, the shaft 22 extends in a direction perpendicular to the clamping direction of the clamp portion 21 and is located at the center in the clamping direction. Therefore, when the first clamp portion 21a clamps the first rising portion 111, the first shaft 22a overlaps the first center line N1 of the first rising portion 111. When the second clamp portion 21b clamps the second rising portion 112, the second shaft 22b overlaps the second center line N2 of the second rising portion 112.

[0045] The shaft portion 22 is rotatable around the mounting portion 34. Therefore, regardless of the angle formed between the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 overlaps the intersection Q of a first imaginary straight line L1 extending from the first shaft portion 22a and a second imaginary straight line L2 extending from the second shaft portion 22b. Therefore, the mounting portion 34 overlaps the reference point P where the first center line N1 and the second center line N2 intersect.

[0046] This allows the worker to easily set the reference point P with respect to the foundation 110 simply by attaching the first mounting member 12a and the second mounting member 12b to the foundation 110 and connecting the first mounting member 12a and the second mounting member 12b via the connecting member 13. Then, by attaching the measuring member 100 to the mounting portion 34, the worker can perform the measurement work alone, without the need for another worker to hold down one end of the measuring member 100 at the reference point P. This improves the workability of the measurement work.

[0047] (1-2) The connecting member 13 has a rail 13a that extends in a circular shape centered on the mounting portion 34. The shaft portion 22 has a slider 25 that is slidable along the rail 13a.

[0048] According to this configuration, the worker can adjust the angle formed by the two shaft portions 22 by sliding the sliders 25 of the shaft portions 22 along the rails 13a. (1-3) The connecting member 13 has an inner circumferential ring 31 and an outer circumferential ring 32 located on the outer periphery of the inner circumferential ring 31. The rail 13a is a gap provided between the outer circumferential surface of the inner circumferential ring 31 and the inner circumferential surface of the outer circumferential ring 32.

[0049] With this configuration, for example, compared to when the groove provided on the upper surface of the plate-shaped member is a rail, components that protrude upward from the object to be measured, such as anchor bolts protruding from the upper surface of the foundation 110, are less likely to interfere with the connecting member 13.

[0050] [Second embodiment] A measurement auxiliary jig 10 according to the second embodiment will be described with reference to Figures 3 to 5. Note that the same components as those in the first embodiment will not be described again and will be denoted by the same reference numerals.

[0051] As shown in FIG. 3, a connecting member 13 is fixed to one end of the first shaft portion 22a in the second embodiment. That is, the connecting member 13 is integrated with the first mounting member 12a. The connecting member 13 in the second embodiment has a plate-shaped base member 35. The base member 35 in this embodiment is circular. The mounting portion 34 protrudes from the upper surface of the base member 35. The mounting portion 34 in this embodiment is cylindrical. A grip portion 26 is provided at one end of the second shaft portion 22b. The grip portion 26 is configured to be able to engage with the mounting portion 34. The grip portion 26 is rotatable around the mounting portion 34. In the second embodiment, the second shaft portion 22b is rotatable around the mounting portion 34.

[0052] In the second embodiment, the shaft portion 22 is provided so as to be slidable in the axial direction of the shaft portion 22 relative to the clamp portion 21. More specifically, a through hole 24h is provided in the connection plate 24 of the clamp portion 21. The through hole 24h passes through the connection plate 24 in a direction perpendicular to the clamping direction. The shaft portion 22 is inserted through the through hole 24h.

[0053] [Operation of the second embodiment] The operation of the second embodiment will be described together with the method of using the measurement auxiliary jig 10 of the second embodiment.

[0054] 4, the worker clamps the first rising portion 111 with the first clamp portion 21a, and clamps the second rising portion 112 with the second clamp portion 21b. As a result, the first mounting member 12a is attached to the first rising portion 111, and the second mounting member 12b is attached to the second rising portion 112. Thus, the measurement auxiliary jig 10 is attached to the foundation 110.

[0055] The shaft 22 extends in a direction perpendicular to the clamping direction of the clamp portion 21 and is located at the center in the clamping direction. Therefore, when the first clamp portion 21a clamps the first rising portion 111, the first shaft 22a overlaps the first center line N1 of the first rising portion 111. When the second clamp portion 21b clamps the second rising portion 112, the second shaft 22b overlaps the second center line N2 of the second rising portion 112.

[0056] 5, the operator slides the first shaft portion 22a relative to the first clamp portion 21a and slides the second shaft portion 22b relative to the second clamp portion 21b, thereby locking the grip portion 26 to the attachment portion 34. This connects the first attachment member 12a and the second attachment member 12b via the connecting member 13.

[0057] The method of attaching the measurement auxiliary jig 10 to the foundation 110 is not limited to the above method. The worker may attach the first attachment member 12a to the first rising portion 111 and the second attachment member 12b to the second rising portion 112 while connecting the first attachment member 12a and the second attachment member 12b via the connecting member 13.

[0058] The second shaft portion 22b is rotatable about the mounting portion 34 of the connecting member 13. Therefore, regardless of the angle formed between the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 overlaps the intersection Q of a first imaginary straight line L1 extending from the first shaft portion 22a and a second imaginary straight line L2 extending from the second shaft portion 22b. Therefore, the mounting portion 34 overlaps the reference point P where the first center line N1 and the second center line N2 intersect.

[0059] This allows the worker to easily set the reference point P with respect to the foundation 110 simply by attaching the first mounting member 12a and the second mounting member 12b to the foundation 110 and connecting the first mounting member 12a and the second mounting member 12b via the connecting member 13. Then, by attaching the measuring member 100 to the mounting portion 34, the worker can perform the measurement work alone, without the need for another worker to hold down one end of the measuring member 100 at the reference point P. This improves the workability of the measurement work.

[0060] [Effects of the second embodiment] In the second embodiment, the following effect can be obtained in addition to the effect (1-1) of the first embodiment. (2-1) The connecting member 13 is fixed to the first shaft portion 22a. The second shaft portion 22b has a grip portion 26 that is engaged with the attachment portion 34 of the connecting member 13.

[0061] This configuration simplifies the configuration of the measurement auxiliary jig 10. Furthermore, since the connecting member 13 is integrated with the first mounting member 12a, the number of parts of the measurement auxiliary jig 10 can be reduced. (2-2) The shaft portion 22 is slidable relative to the clamp portion 21 in the axial direction of the shaft portion 22.

[0062] According to this configuration, after the first mounting member 12a and the second mounting member 12b are attached to the foundation 110, the grip portion 26 can be locked to the mounting portion 34 by sliding the shaft portion 22.

[0063] <Example of change> The above-described embodiment is an example of a form that the measurement auxiliary jig 10 can take, and is not intended to limit the form. The measurement auxiliary jig 10 can take a form different from the form exemplified in the above-described embodiment. Such forms include a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0064] In each embodiment, the measurement target is not limited to the base 110. As shown in FIGS. 6 and 7, the foundation 110 is formed using a foundation formwork 120. The foundation formwork 120 is made of steel. The foundation formwork 120 has two side panels 120a spaced apart from each other and two flanges 120b extending away from each other from the upper ends of the two side panels 120a. In the example shown in FIGS. 6 and 7, a ruler plate 130 is placed on the foundation formwork 120. Clips or pins (not shown) are attached to the foundation formwork 120 and the ruler plate 130.

[0065] The foundation formwork 120 has a first forming section 121 for forming the first rising section 111 and a second forming section 122 for forming the second rising section 112. Although not shown, the second forming section 122 intersects with the first forming section 121. The first rising section 111 is formed by hardening concrete poured between the two side plates 120a of the first forming section 121. The second rising section 112 is formed by hardening concrete poured between the two side plates 120a of the second forming section 122. In this case, the measurement object is the foundation formwork 120. The first portion of the measurement object is the first forming section 121. The second portion of the measurement object is the second forming section 122.

[0066] In the above embodiments, one end of the first part of the measurement target intersects with one end of the second part of the measurement target, but this is not limited to this. For example, one end of one of the first and second parts may intersect with a midpoint in the direction in which the other part extends. In other words, the intersection 110a between the first and second parts does not have to form a corner.

[0067] In each embodiment, the first and second portions of the measurement object do not have to be perpendicular to each other as long as they intersect. In the first embodiment, the connecting member 13 may have the base member 35 of the second embodiment instead of the inner ring 31, the outer ring 32, and the ring connecting portion 33. The mounting portion 34 protrudes from the center of the base member 35. In this case, the rail 13a may be a groove portion that is provided on the upper surface of the base member 35 and extends in a circular shape centered on the mounting portion 34.

[0068] In the first embodiment, the shaft 22 may be slidable in the axial direction of the shaft 22 relative to the clamp 21. In this case, the position of the clamp 21 relative to the object to be measured can be adjusted. This makes it less likely that the connection plate 24 will interfere with components that protrude upward from the object to be measured, such as anchor bolts that protrude from the top surface of the foundation 110.

[0069] In the second embodiment, the connecting member 13 may be fixed to the second shaft portion 22b, and the first shaft portion 22a may have the grip portion 26. In this case, the first shaft portion 22a is rotatable around the attachment portion 34.

[0070] In each embodiment, the clamp portion 21 may be configured as follows. <First change example> As shown in FIGS. 6 and 7, the clamp portion 21 of the first modified example has a base portion 41, two support shafts 42, two clamping portions 43, and two connecting members 44.

[0071] A through hole 41h is provided in the base 41. The through hole 41h penetrates the base 41 in a direction perpendicular to the clamping direction. The shaft 22 is inserted into the through hole 41h. The two support shafts 42 extend from both end faces of the base 41 in the clamping direction.

[0072] The two clamping portions 43 are portions that clamp the measurement object. Clamping portion 43 of the first modified example has a main body portion 51, an upper horizontal portion 52a, a lower horizontal portion 52b, a first extending portion 53 and a second extending portion 54 that are extending portions, and a magnet 55. Main body portion 51, upper horizontal portion 52a, lower horizontal portion 52b, first extending portion 53, and second extending portion 54 are each plate-shaped.

[0073] When the clamp unit 21 clamps the measurement object, the main body unit 51 fits along the side of the measurement object. An insertion hole 51h is provided in the upper part of the main body unit 51. The insertion hole 51h passes through the main body unit 51 in the clamping direction. A support shaft 42 is inserted through the insertion hole 51h. The clamp unit 43 is supported by the support shaft 42.

[0074] The upper horizontal portion 52a extends from a portion of the main body 51 that is located above the insertion hole 51h toward the base 41. The lower horizontal portion 52b extends from a portion of the main body 51 that is located below the insertion hole 51h toward the base 41. The support shaft 42 is located between the upper horizontal portion 52a and the lower horizontal portion 52b.

[0075] The first extending portion 53 extends from the lower end of the main body portion 51 toward the base portion 41. The second extending portion 54 extends downward from the tip end of the first extending portion 53. The magnet 55 is provided on the upper surface of the first extending portion 53.

[0076] The connecting member 44 of the first modified example includes a spring 44c. The connecting member 44 connects the base 41 and the clipping portion 43. More specifically, a first end of the connecting member 44 is fixed to the base 41. A second end of the connecting member 44 is fixed to a portion of the main body 51 that is located between the upper horizontal portion 52a and the lower horizontal portion 52b. The connecting member 44 is located between the upper horizontal portion 52a and the lower horizontal portion 52b.

[0077] The clamping portions 43 are movable in the clamping direction along the support shaft 42 relative to the base 41. Therefore, the distance between the two clamping portions 43 in the clamping direction is variable. As shown in FIG. 7 , when the two clamping portions 43 are close to each other, the two upper horizontal portions 52a overlap each other above the base 41. The two lower horizontal portions 52b overlap each other below the base 41.

[0078] 6, when clamping the foundation formwork 120 to be measured with the clamp unit 21, the worker moves the two clamping units 43 away from each other to widen the gap between the two clamping units 43. With the gap between the two clamping units 43 widened, the worker positions the clamp unit 21 so that the two main units 51 are located on both sides of the foundation formwork 120.

[0079] 7, when the worker stops widening the gap between the two clamping members 43, the two clamping members 43 are urged toward each other by the compressive force of the spring 44c. As a result, the foundation formwork 120 is clamped between the two clamping members 43. That is, the foundation formwork 120 is clamped by the clamping member 21.

[0080] When the clamp unit 21 clamps the foundation formwork 120, the first extension unit 53 is located below the flange 120b of the foundation formwork 120. The tip of the first extension unit 53 and the second extension unit 54 contact the outer surface of the side panel 120a of the foundation formwork 120. The magnet 55 provided on the upper surface of the first extension unit 53 is attached to the lower surface of the flange 120b by magnetic force, causing the clamp unit 21 to float above the upper surface of the foundation formwork 120. In the example shown in FIG. 7, a gap is created between the upper surface of the ruler plate 130 placed on the foundation formwork 120 and the lower surface of the lower horizontal unit 52b.

[0081] <Second modification example> As shown in FIGS. 8 to 11, the clamping portion 21 of the second modified example has a base portion 41, a support shaft 42, two clamping portions 43, and two connecting members 44.

[0082] The base 41 has an upper plate 41a, a lower plate 41b, and a shaft support tube 45. The upper plate 41a is located above the lower plate 41b. The shaft support tube 45 is fixed to the upper surface of the upper plate 41a. The shaft support tube 45 extends in a direction perpendicular to the clamping direction. The shaft portion 22 is inserted through the shaft support tube 45. The support shaft 42 is located between the upper plate 41a and the lower plate 41b. The support shaft 42 extends in the clamping direction.

[0083] The two clamping portions 43 are portions that clamp the object to be measured. The clamping portion 43 of the second modified example has a main body portion 51 and a horizontal portion 52 provided at the upper end of the main body portion 51. When the clamp portion 21 clamps the object to be measured, the main body portion 51 follows the side surface of the object to be measured. A portion of the horizontal portion 52 is inserted between the upper plate 41a and the lower plate 41b. The horizontal portion 52 has an insertion hole 52h. The insertion hole 52h extends in the clamping direction. The support shaft 42 is inserted through the insertion holes 52h of the two horizontal portions 52. The clamping portion 43 is supported by the support shaft 42. The two clamping portions 43 are movable in the clamping direction along the support shaft 42 relative to the base portion 41. Therefore, the distance between the two clamping portions 43 in the clamping direction is variable.

[0084] A buckle 46 is provided on the upper surface of the upper plate 41a of the base 41. The buckle 46 is attached to the base 41 so as to be rotatable about a first rotation shaft 47 as a rotation shaft. The first rotation shaft 47 extends in a direction perpendicular to the clamping direction.

[0085] A plurality of hooks 56 are provided in the clamping direction on the upper surface of the horizontal portion 52 of the clipping portion 43. In the second modified example, two hooks 56 are provided on the clipping portion 43. The two hooks 56 include an outer hook 56a and an inner hook 56b that is located closer to the base portion 41 than the outer hook 56a.

[0086] The connecting member 44 of the second modified example has a first connecting portion 44a, a second connecting portion 44b, and a spring 44c connecting the first connecting portion 44a and the second connecting portion 44b. The connecting member 44 connects the base portion 41 and the clip portion 43. Specifically, a first end of the first connecting portion 44a is attached to the buckle 46 so as to be rotatable about a second rotation shaft 44d. The second rotation shaft 44d extends parallel to the first rotation shaft 47. A second end of the first connecting portion 44a is connected to a first end of the spring 44c. A first end of the second connecting portion 44b is configured to be hooked onto a hook 56. A second end of the second connecting portion 44b is connected to a second end of the spring 44c. Therefore, the first end of the connecting member 44 is connected to the buckle 46. The second end of the connecting member 44 is hooked onto the hook 56.

[0087] The second connecting portion 44b is hooked onto the outer hook 56a or the inner hook 56b. As shown in Figures 8 and 9, when the width of the base 110 is a first width, the second connecting portion 44b is hooked onto the outer hook 56a. As shown in Figures 10 and 11, when the width of the base 110 is a second width that is larger than the first width, the second connecting portion 44b is hooked onto the inner hook 56b.

[0088] 8 and 10, the worker positions the clamp unit 21 so that the two main body units 51 are positioned on both sides of the foundation 110 to be measured. The main body units 51 come into contact with the side surfaces of the foundation 110.

[0089] 9 and 11, the operator rotates the buckle 46 in a direction that brings it closer to the shaft 22. When the buckle 46 rotates in a direction that brings it closer to the shaft 22, the spring 44c of the connecting member 44 connected to the buckle 46 is stretched. As a result, the two clamping portions 43 are biased in directions that bring them closer to each other by the compressive force of the stretched spring 44c.

[0090] In the first and second modified examples, the clamp unit 21 has two clamping parts 43 that clamp the measurement object. The distance between the two clamping parts 43 is changeable. According to this configuration, the distance between the two clipping portions 43 can be changed, so that it is possible to accommodate a variety of measurement targets with different widths.

[0091] In the first and second modified examples, the clamping portion 21 has a base portion 41 and a connecting member 44 that connects the base portion 41 and the clip portion 43. The connecting member 44 includes a spring 44c. According to this configuration, the two pinching parts 43 are biased toward each other by the compressive force of the spring 44c, and therefore the clamp part 21 can stably clamp the measurement object.

[0092] In the second modified example, a buckle 46 is provided on the base 41. The buckle 46 is rotatable around a first rotation axis 47 that extends parallel to the axial direction of the shaft portion 22. A first end of the connecting member 44 is coupled to the buckle 46.

[0093] According to this configuration, when buckle 46 is rotated so as to approach shaft 22, spring 44c of connecting member 44 connected to buckle 46 is stretched, increasing the force that urges two clamping portions 43 toward each other. Therefore, clamp portion 21 can more stably clamp the measurement object.

[0094] In the second modified example, the clip portion 43 is provided with a plurality of hooks 56 in the clamping direction, on which the second end of the connecting member 44 is hooked. According to this configuration, by changing the hook 56 for hooking the connecting member 44 depending on the width of the first or second portion, it is possible to reduce the elongation rate of the spring 44c even when the width of the first or second portion is large. Therefore, the operator can use a stronger spring with a larger spring constant as the spring 44c of the connecting member 44, and the clamp portion 21 is less likely to slip even when the measuring member 100 is installed on the mounting portion 34 and pulled for measurement. In addition, the buckle 46 can be easily rotated.

[0095] In the first modified example, the clamping portion 43 has a main body portion 51 that follows the side surface of the object to be measured, a first extension portion 53 that extends from the lower end of the main body portion 51 toward the base portion 41, and a magnet 55 provided on the upper surface of the first extension portion 53.

[0096] With this configuration, when the measurement target is the foundation formwork 120, the mounting member 12 can be appropriately mounted to the foundation formwork 120. More specifically, when the clamp unit 21 clamps the foundation formwork 120, the first extension unit 53 is positioned below the flange 120b of the foundation formwork 120. The magnet 55 provided on the upper surface of the first extension unit 53 attaches to the lower surface of the flange 120b, causing the measurement auxiliary jig 10 to float above the upper surface of the foundation formwork 120. Therefore, members protruding upward from the foundation formwork 120 are less likely to interfere with the measurement auxiliary jig 10, and the mounting member 12 can be appropriately mounted to the foundation formwork 120.

[0097] In the first modified example, the clip portion 43 has a second extending portion 54 extending downward from the tip end of the first extending portion 53. According to this configuration, the contact area between clamping portion 43 and the measurement object is larger than when clamping portion 43 does not have second extending portion 54. Therefore, clamp portion 21 can clamp the measurement object more stably.

[0098] In the first modification, the measurement object may be the foundation 110. In the second modified example, the measurement object may be the foundation formwork 120. In the first and second modified examples, the connecting member 44 does not have to include the spring 44c. In this case, the clamping portion 21 is configured so that the distance between the two clipping portions 43 can be fixed at any distance.

[0099] In the second modified example, the number of hooks 56 provided on the clip portion 43 is not limited to two. The number of hooks 56 may be one, or may be three or more. In the second modified example, the connecting member 44 does not have to have the first connecting portion 44a. In this case, the first end of the spring 44c is connected to the buckle 46.

[0100] In the second modified example, the connecting member 44 does not have to have the second connecting portion 44b. In this case, the second end of the spring 44c is hooked onto the hook 56. In the first modified example, the clip portion 43 does not necessarily have to have the first extending portion 53, the second extending portion 54, and the magnet 55.

[0101] In the first modified example, the clip portion 43 may have the first extending portion 53 and the magnet 55, but may not have the second extending portion . In the second modified example, the clip portion 43 may have a first extending portion 53, a second extending portion 54, and a magnet 55, as in the first modified example.
