Summary of the Invention

Problems to be Solved by the Invention

[0005] The worker must measure the dimensions of the first and second parts to set the first and second grid lines and the reference point. Therefore, the worker must measure the dimensions of the first and second parts each time the position of the reference point changes. In addition, the measurement work requires two workers: one to hold one end of the measuring member at the reference point and another to check the numerical value of the measuring member at the designated position. [Means for solving the problem]

[0006] (1) A measuring aid jig that solves the above problem is a measuring aid jig that assists in measuring a distance from a first reference point to a predetermined position using a measuring member, for a measurement target having a first part and a second part intersecting the first part, by setting a reference point where the first center line of the first part and the second center line of the second part intersect, and comprising a first mounting member attached to the first part, a second mounting member attached to the second part, and a connecting member connecting the first mounting member and the second mounting member, wherein the first mounting member and the second mounting member each have a clamping portion for clamping the measurement target and a shaft 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 a mounting portion to which the measuring member is attached, and at least one of the two shaft portions is rotatable about the mounting portion.

[0007] In this configuration, the shaft extends in a direction perpendicular to the clamping direction and is located at the center in the clamping direction. Therefore, when the clamping portion of the first mounting member clamps the first part of the object to be measured, the shaft aligns with the first centerline. When the clamping portion of the second mounting member clamps the second part of the object to be measured, the shaft aligns with the second centerline.

[0008] At least one of the two shaft portions is rotatable around the mounting portion. Therefore, regardless of the angle between the two shaft portions, the mounting portion coincides with the intersection of a first virtual line, which is an extension of the shaft portion of the first mounting member, and a second virtual line, which is an extension of the shaft portion of the second mounting member. Consequently, the mounting portion coincides with the reference point where the first and second grid lines intersect.

[0009] This allows the operator to easily set a reference point relative to the object to be measured simply by attaching the first and second mounting members to the object and connecting the first and second mounting members via a connecting member. Furthermore, by attaching the measuring member to the mounting part, the operator can measure the distance from the reference point to a predetermined position by themselves, without the need for another operator to hold one end of the measuring member at the reference point. Thus, the efficiency of the measurement work is improved.

[0010] (2) In the measuring aid jig of (1) above, the connecting member has a rail that extends in a circular shape from the mounting portion, and the shaft portion has a slider that is slidable along the rail. With this configuration, the operator can adjust the angle between the two shafts by sliding the slider on the shaft along the rail.

[0011] (3) In the measuring aid jig described in (2) above, the connecting member comprises an inner ring and an outer ring located on the outer circumference 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 a case where the groove provided on the upper surface of a plate-shaped member is a rail, members that protrude upward from the object being measured, such as anchor bolts protruding from the upper surface of the foundation, are less likely to interfere with the connecting member.

[0013] (4) In the measuring aid jig described in (1) above, 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 is locked to the mounting portion.

[0014] This configuration simplifies the structure of the measurement aid jig. Furthermore, since the connecting member is integrated with either the first or second mounting member, the number of parts in the measurement aid jig can be reduced.

[0015] (5) In the measuring aid jig of (4) above, the shaft portion is slidable in the axial direction of the shaft portion relative to the clamp portion. With this configuration, after attaching the first and second mounting members to the object to be measured, the operator can lock the grip portion to the mounting portion by sliding the shaft portion.

[0016] (6) In any one of the measuring aids described in (1) to (5) above, the clamp portion has two clamping portions that hold the object to be measured, and the distance between the two clamping portions is adjustable. This configuration allows for adjustment of the distance between the two clamping sections, enabling it to accommodate multiple types of objects with different widths.

[0017] (7) In the measuring aid jig described in (6) above, the clamp portion comprises a base and a connecting member that connects the base and the clamping portion, and the connecting member includes a spring. In this configuration, the two clamping parts are biased to move closer to each other by the force of the compressed spring. Therefore, the clamping part can stably clamp the object to be measured.

[0018] (8) In the measuring aid jig of (6) above, the clamp portion has a base and a connecting member that connects the base and the clamping portion, the connecting member includes a spring, the base is provided with a buckle that is rotatable about a rotation axis that extends parallel to the axial direction of the shaft portion, and the first end of the connecting member is connected to the buckle.

[0019] In this configuration, the two clamping parts are biased to move closer to each other by the force of the compressed spring. Therefore, the clamping part can stably clamp the object to be measured. Furthermore, a buckle is provided at the base. The first end of the connecting member is connected to the buckle. Therefore, when the buckle is rotated so that it approaches the shaft, the spring of the connecting member connected to the buckle is stretched, increasing the force that biases the two clamping parts toward each other. Consequently, the clamping part can clamp the object to be measured more stably.

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

[0021] (10) In any one of the measuring aids described in (7) to (9) above, the clamping portion comprises 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] This configuration allows the mounting member to be properly attached to the foundation formwork when the object to be measured is the foundation formwork. Specifically, the foundation formwork has two side plates and two flanges extending away from each other from the upper ends of the two side plates. With the above configuration, the clamping part has an extension that extends 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 clamping part is clamped to the foundation formwork, the extension is located below the flange. The magnet provided on the upper surface of the extension is attracted to the lower surface of the flange by magnetic force, causing the measuring aid jig to float above the upper surface of the foundation formwork. Consequently, members protruding upward from the upper surface of the foundation formwork are less likely to interfere with the measuring aid jig, allowing the mounting member to be properly attached to the foundation formwork. [Effect of the Invention]

[0023] According to the measurement assistance jig of the present disclosure, the workability of the measurement work is improved. [Brief Description of the Drawings]

[Mode for Carrying Out the Invention]

[0025] [First Embodiment] Referring to FIGS. 1 and 2, the measurement assistance jig 10 of the first embodiment will be described. The measurement assistance jig 10 is a jig for assisting an operator in performing a measurement operation of measuring the dimensions of a measurement object using a measurement member 100. The measurement object in this embodiment is the foundation 110. The measurement member 100 is, for example, a steel tape.

[0026] <Basics> As shown in Figure 1, the foundation 110 has a first rising portion 111, which is a first part, and a second rising portion 112, which is a second part. 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, the intersection 110a of the first rising portion 111 and the second rising portion 112 forms a corner.

[0027] To measure the dimensions of the foundation 110, a first grid line N1 is set in the first rising section 111. The first grid line N1 extends along the direction in which the first rising section 111 extends. The first grid line N1 is located at the center of the first rising section 111 in the width direction. The width direction of the first rising section 111 is the horizontal direction perpendicular to the direction in which the first rising section 111 extends.

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

[0029] A reference point P is set on the foundation 110. 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 reference point P to a predetermined position using a measuring member 100. The predetermined position is, for example, another reference point.

[0030] <Measurement aid jig> As shown in Figures 1 and 2, the measuring aid jig 10 comprises 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. The first mounting member 12a and the second mounting member 12b each have 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 rising portion 111. The clamp portion 21 of the second mounting member 12b clamps the second rising portion 112. The clamp portion 21 has two clamp plates 23 and a connecting plate 24. The two clamp plates 23 sandwich the first rising portion 111 or the second rising portion 112 in the width direction. The connecting 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. In the first embodiment, the shaft portion 22 is fixed to the upper surface of the connecting plate 24. A slider 25 is provided at one end of the shaft portion 22. The slider 25 is arc-shaped and follows 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 connecting member 13 of the first embodiment has a circular inner ring 31, a circular outer ring 32, a ring connecting portion 33, and a mounting portion 34. 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 circumference of the inner ring 31. The center of the outer ring 32 is the same as the center of the inner ring 31. The rail 13a is formed by the gap between the outer surface of the inner ring 31 and the inner surface of the outer ring 32.

[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] A measuring member 100 is attached to the mounting portion 34. The mounting portion 34 is provided on the upper surface of the ring connection portion 33. The mounting 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 around the mounting portion 34.

[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 explained along with the method of using the measurement aid jig 10 of the first embodiment.

[0038] The worker locks the sliders 25 of the first shaft portion 22a and the second shaft portion 22b onto the rail 13a of the connecting member 13. This connects the first mounting member 12a and the second mounting member 12b via the connecting member 13. Subsequently, the worker clamps the first rising portion 111 with the first clamp portion 21a and the second rising portion 112 with the second clamp portion 21b. This attaches the first mounting member 12a to the first rising portion 111 and the second mounting member 12b to the second rising portion 112. Thus, the measuring aid jig 10 is attached to the foundation 110.

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

[0040] The shaft portion 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 portion 22a aligns with 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 portion 22b aligns with 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 around the mounting portion 34. Therefore, regardless of the angle between the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 coincides with the intersection point Q of the first virtual line L1, which is an extension of the first shaft portion 22a, and the second virtual line L2, which is an extension of the second shaft portion 22b. Consequently, the mounting portion 34 coincides with the reference point P where the first center line N1 and the second center line N2 intersect.

[0042] As a result, the worker can easily set a reference point P on 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. Furthermore, by attaching the measuring member 100 to the mounting part 34, the worker can perform the measurement work alone without the need for another worker to hold one end of the measuring member 100 at the reference point P. Thus, the work efficiency of the measurement work is improved.

[0043] [Effects of the First Embodiment] The effects of the first embodiment will be explained. (1-1) The measuring aid jig 10 comprises 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 of the foundation 110. The second mounting member 12b is attached to the 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 have 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 in the clamping direction. The connecting member 13 has a mounting portion 34 to which the measuring member 100 is attached. The shaft portion 22 is rotatable about the mounting portion 34.

[0044] In this configuration, the shaft portion 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 portion 22a aligns with 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 portion 22b aligns with 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 between the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 coincides with the intersection point Q of the first virtual line L1, which is an extension of the first shaft portion 22a, and the second virtual line L2, which is an extension of the second shaft portion 22b. Consequently, the mounting portion 34 coincides with the reference point P where the first center line N1 and the second center line N2 intersect.

[0046] As a result, the worker can easily set a reference point P on 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. Furthermore, by attaching the measuring member 100 to the mounting part 34, the worker can perform the measurement work alone without the need for another worker to hold one end of the measuring member 100 at the reference point P. Thus, the work efficiency of the measurement work is improved.

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

[0048] With this configuration, the operator can adjust the angle between the two shafts 22 by sliding the slider 25 of the shaft 22 along the rail 13a. (1-3) The connecting member 13 has an inner circumferential ring 31 and an outer circumferential ring 32 located on the outer circumference 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 a case where 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 protruding from the upper surface of the foundation 110, are less likely to interfere with the connecting member 13.

[0050] [Second Embodiment] The measurement assist jig 10 of the second embodiment will be described with reference to Figures 3 to 5. Note that the same components as in the first embodiment will not be described and will be denoted by the same reference numerals.

[0051] As shown in Figure 3, a connecting member 13 is fixed to one end of the first shaft portion 22a of the second embodiment. That is, the connecting member 13 is integrated with the first mounting member 12a. The connecting member 13 of the second embodiment has a plate-shaped base member 35. The base member 35 of this embodiment is circular in shape. The mounting portion 34 protrudes from the upper surface of the base member 35. The mounting portion 34 of this embodiment is cylindrical in shape. A grip portion 26 is provided at one end of the second shaft portion 22b. The grip portion 26 is configured to be lockable to 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 relative to the clamp portion 21. Specifically, the connecting plate 24 of the clamp portion 21 is provided with a through hole 24h. The through hole 24h penetrates the connecting 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 explained along with the method of using the measurement aid jig 10 of the second embodiment.

[0054] As shown in Figure 4, the worker clamps the first rising portion 111 with the first clamping portion 21a and the second rising portion 112 with the second clamping 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 measuring aid jig 10 is attached to the foundation 110.

[0055] The shaft portion 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 portion 22a aligns with 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 portion 22b aligns with the second center line N2 of the second rising portion 112.

[0056] As shown in Figure 5, the operator locks the grip portion 26 to the mounting portion 34 by sliding the first shaft portion 22a relative to the first clamp portion 21a and the second shaft portion 22b relative to the second clamp portion 21b. This connects the first mounting member 12a and the second mounting member 12b via the connecting member 13.

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

[0058] The second shaft portion 22b is rotatable around the mounting portion 34 of the connecting member 13. Therefore, regardless of the angle between the first shaft portion 22a and the second shaft portion 22b, the mounting portion 34 coincides with the intersection point Q of the first virtual line L1, which is an extension of the first shaft portion 22a, and the second virtual line L2, which is an extension of the second shaft portion 22b. Consequently, the mounting portion 34 coincides with the reference point P where the first center line N1 and the second center line N2 intersect.

[0059] As a result, the worker can easily set a reference point P on 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. Furthermore, by attaching the measuring member 100 to the mounting part 34, the worker can perform the measurement work alone without the need for another worker to hold one end of the measuring member 100 at the reference point P. Thus, the work efficiency of the measurement work is improved.

[0060] [Effects of the second embodiment] In the second embodiment, in addition to the effects of (1-1) of the first embodiment, the following effects are obtained. (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 locked to the mounting portion 34 of the connecting member 13.

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

[0062] With this configuration, after attaching the first mounting member 12a and the second mounting member 12b 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 changes> The above embodiments are illustrative of possible forms of the measurement assistance jig 10 and are not intended to limit its form. The measurement assistance jig 10 may take forms different from those illustrated in the above embodiments. Examples include forms in which some of the configurations of the embodiments are replaced, modified, or omitted, or forms in which new configurations are added to the embodiments. Examples of modifications to the embodiments are shown below.

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

[0065] The foundation formwork 120 has a first forming section 121 for forming a first rising section 111 and a second forming section 122 for forming a 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 the hardening of concrete poured between the two side plates 120a of the first forming section 121. The second rising section 112 is formed by the hardening of concrete poured between the two side plates 120a of the second forming section 122. In this case, the object of measurement is the foundation formwork 120. The first part of the object of measurement is the first forming section 121. The second part of the object of measurement is the second forming section 122.

[0066] In the embodiments described above, one end of the first part to be measured and one end of the second part to be measured intersect, but this is not limited to this. For example, one end of the first part and the second part may intersect with a portion of the other part in the direction in which it extends. In other words, the intersection 110a of the first part and the second part does not have to form a corner.

[0067] In each embodiment, the first and second parts of the object to be measured do not need to be orthogonal, 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 provided on the upper surface of the base member 35 and extending in a circular shape around the mounting portion 34.

[0068] In the first embodiment, the shaft portion 22 may be slidable in the axial direction relative to the clamp portion 21. In this case, the position of the clamp portion 21 relative to the object to be measured can be adjusted. Therefore, the connecting plate 24 is less likely to interfere with members that protrude upward from the object to be measured, such as anchor bolts protruding from the upper surface of the foundation 110.

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

[0070] In each embodiment, the clamp portion 21 may be configured as follows: <Example of first change> As shown in Figures 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] The base portion 41 is provided with a through hole 41h. The through hole 41h penetrates the base portion 41 in a direction perpendicular to the clamping direction. The shaft portion 22 is inserted through the through hole 41h. The two support shafts 42 extend from both end faces of the base portion 41 in the clamping direction.

[0072] The two clamping parts 43 are the parts that clamp the object to be measured. The clamping part 43 of the first modified example has a main body 51, an upper horizontal part 52a, a lower horizontal part 52b, an extension part which is a first extension part 53, a second extension part 54, and a magnet 55. The main body 51, the upper horizontal part 52a, the lower horizontal part 52b, the first extension part 53, and the second extension part 54 are each plate-shaped.

[0073] When the clamp portion 21 is clamping the object to be measured, the main body portion 51 is aligned with the side of the object to be measured. An insertion hole 51h is provided in the upper part of the main body portion 51. The insertion hole 51h penetrates the main body portion 51 in the clamping direction. A support shaft 42 is inserted through the insertion hole 51h. The clamping portion 43 is supported by the support shaft 42.

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

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

[0076] The connecting member 44 in the first modified example includes a spring 44c. The connecting member 44 connects the base 41 and the clamping portion 43. Specifically, the first end of the connecting member 44 is fixed to the base 41. The second end of the connecting member 44 is fixed to the portion of the main body 51 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 portion 43 is 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 can be changed. As shown in Figure 7, when the two clamping portions 43 are close to each other, the two upper horizontal portions 52a overlap above the base portion 41. The two lower horizontal portions 52b overlap below the base portion 41.

[0078] As shown in Figure 6, when the worker clamps the foundation formwork 120 to be measured with the clamp section 21, the worker widens the distance between the two clamping sections 43 by moving them away from each other. With the distance between the two clamping sections 43 widened, the worker positions the clamp section 21 so that the two main body sections 51 are located on both sides of the foundation formwork 120.

[0079] As shown in Figure 7, when the worker stops widening the distance between the two clamping parts 43, the two clamping parts 43 are biased toward each other by the force of the spring 44c compressing. As a result, the foundation formwork 120 is clamped by the two clamping parts 43. In other words, the foundation formwork 120 is clamped by the clamp part 21.

[0080] When the clamp portion 21 is clamped to the foundation formwork 120, the first extension portion 53 is located below the flange 120b of the foundation formwork 120. The tip of the first extension portion 53 and the second extension portion 54 are in contact with the outer surface of the side plate 120a of the foundation formwork 120. The magnet 55 provided on the upper surface of the first extension portion 53 is attracted to the lower surface of the flange 120b by magnetic force, causing the clamp portion 21 to float above the upper surface of the foundation formwork 120. In the example shown in Figure 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 portion 52b.

[0081] <Example of second change> As shown in Figures 8 to 11, the clamp 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 support tube 45. The upper plate 41a is located above the lower plate 41b. The support tube 45 is fixed to the upper surface of the upper plate 41a. The support tube 45 extends in a direction perpendicular to the clamping direction. The shaft portion 22 is inserted through the 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 the parts 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 is clamping the object to be measured, the main body portion 51 is along the side of the object to be measured. Part of the horizontal portion 52 is inserted between the upper plate 41a and the lower plate 41b. The horizontal portion 52 is provided with 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 along the support shaft 42 in the clamping direction relative to the base portion 41. Therefore, the distance between the two clamping portions 43 in the clamping direction can be changed.

[0084] A buckle 46 is provided on the upper surface of the upper plate 41a of the base 41. The buckle 46 is rotatably mounted to the base 41 around a first rotation axis 47, which serves as the axis of rotation. The first rotation axis 47 extends in a direction perpendicular to the clamping direction.

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

[0086] The connecting member 44 in the second modified example has a first connecting portion 44a, a second connecting portion 44b, and a spring 44c that connects the first connecting portion 44a and the second connecting portion 44b. The connecting member 44 connects the base portion 41 and the clamping portion 43. Specifically, the first end of the first connecting portion 44a is rotatably attached to the buckle 46 around the second rotation axis 44d. The second rotation axis 44d extends parallel to the first rotation axis 47. The second end of the first connecting portion 44a is connected to the first end of the spring 44c. The first end of the second connecting portion 44b is configured to be hooked onto the hook 56. The second end of the second connecting portion 44b is connected to the 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 either the outer hook 56a or the inner hook 56b. As shown in Figures 8 and 9, when the width of the foundation 110 is the 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 foundation 110 is the second width, which is greater than the first width, the second connecting portion 44b is hooked onto the inner hook 56b.

[0088] As shown in Figures 8 and 10, the worker positions the clamp 21 so that the two main body parts 51 are located on both sides of the foundation 110 to be measured. The main body parts 51 are in contact with the sides of the foundation 110.

[0089] As shown in Figures 9 and 11, the operator rotates the buckle 46 in a direction that brings it closer to the shaft portion 22. When the buckle 46 rotates in a direction that brings it closer to the shaft portion 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 toward each other by the force of the stretched spring 44c contracting.

[0090] In the first and second modification examples, the clamp portion 21 has two clamping portions 43 that hold the object to be measured. The distance between the two clamping portions 43 is adjustable. With this configuration, the distance between the two clamping parts 43 can be changed, allowing it to accommodate multiple types of measurement targets with different widths.

[0091] In the first and second modified examples, the clamp portion 21 has a base portion 41 and a connecting member 44 that connects the base portion 41 and the clamping portion 43. The connecting member 44 includes a spring 44c. In this configuration, the two clamping portions 43 are biased to move closer to each other by the force of the spring 44c compressing. Therefore, the clamp portion 21 can stably clamp the object to be measured.

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

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

[0094] In the second modified example, the clamping portion 43 is provided with multiple hooks 56 in the clamping direction, onto which the second end of the connecting member 44 is hooked. With this configuration, by changing the hook 56 that hooks the connecting member 44 according to the width of the first or second part, the elongation rate of the spring 44c can be reduced even when the width of the first or second part 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 part 21 will not easily shift even when the measuring member 100 is installed on the mounting part 34 and pulled for measurement. In addition, the buckle 46 will be easier to rotate.

[0095] In the first modified example, the clamping portion 43 includes a main body portion 51 that follows the side 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 object to be measured is the foundation formwork 120, the mounting member 12 can be properly attached to the foundation formwork 120. Specifically, when the clamp portion 21 is clamped to the foundation formwork 120, the first extension portion 53 is located below the flange 120b of the foundation formwork 120. The magnet 55 provided on the upper surface of the first extension portion 53 sticks to the lower surface of the flange 120b, causing the measurement assist jig 10 to float above the upper surface of the foundation formwork 120. Therefore, the member protruding upward from the foundation formwork 120 is less likely to interfere with the measurement assist jig 10, allowing the mounting member 12 to be properly attached to the foundation formwork 120.

[0097] In the first modified example, the clamping portion 43 has a second extension portion 54 that extends downward from the tip of the first extension portion 53. With this configuration, the contact area between the clamping portion 43 and the object to be measured is larger compared to the case where the clamping portion 43 does not have the second extension portion 54. Therefore, the clamping portion 21 can clamp the object to be measured more stably.

[0098] In the first example of modification, the measurement target may also be the base 110. In the second example of modification, the measurement target may also be the foundation formwork 120. In the first and second modified examples, the connecting member 44 does not need to include the spring 44c. In this case, the clamp portion 21 is configured to fix the distance between the two clamping portions 43 at any desired distance.

[0099] In the second modified example, the number of hooks 56 provided on the clamping portion 43 is not limited to two. The number of hooks 56 may be one or three or more. In the second modified example, the connecting member 44 does not need 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 need to have a 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 clamping portion 43 does not necessarily have to have the first extension portion 53, the second extension portion 54, and the magnet 55.

[0101] In the first modified example, the clamping portion 43 has a first extension portion 53 and a magnet 55, but does not necessarily have a second extension portion 54. In the second modified example, the clamping portion 43 may have a first extension portion 53, a second extension portion 54, and a magnet 55, as in the first modified example.
