Description

[Technical Field]

[0001] The present invention relates to a measuring jig, and more particularly to a measuring jig that is used when measuring a building component with a measuring instrument and is attached to the tip of the building component. [Background technology]

[0002] Conventionally, when measuring the length of a building component using a measuring tool (e.g., a tape measure), the reference point (zero point) is set to the base end of the building component, and the measuring tape of the measuring tool is aligned with the tip of the building component and the scale is read to measure the overall length of the building component. Generally, construction components have base plates and accessory parts (such as gusset plates, locking parts for installing work floors that serve as temporary scaffolding, diaphragms, joint panels, etc.) welded to them. Therefore, in order to measure the length of a construction component in accordance with the shape of the base plate or accessory part, it was necessary to abut a curved ruler against the tip of the construction component, place the measuring tape of a measuring instrument on the curved ruler, and read the scale. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Registered Utility Model No. 3047283 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, a connecting member (e.g., a backing metal) is attached to the inner surface of the tip of a building component, and the building components are connected and welded together using the backing metal. Therefore, when measuring a building component with a backing metal attached, two workers are required: one to place the curved ruler on the tip of the building component, and the other to hold the measuring tool and read the scale, which makes the measurement difficult. There is also a risk of unstable measurement accuracy. Although a measurement auxiliary device such as that disclosed in Patent Document 1 has been proposed, there is a risk that the measurement auxiliary device may not be able to be stably attached to the tip of the construction component while avoiding the backing metal.

[0005] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a measuring jig that can be stably attached to the tip of a building component on which a connecting member is arranged, and that can perform accurate and easy measurements. [Means for solving the problem]

[0006] The above problem is solved by the measuring jig of the present invention, which is used when measuring the length of a building component with a measuring instrument and is attached to the tip of the building component, and which comprises: a base portion that is placed on the outer surface of the building component, extends along the outer surface of the building component, and protrudes beyond the tip of the building component; a contact portion that extends from the protruding portion of the base portion in an orthogonal direction that is orthogonal to the extending direction of the base portion and abuts against the tip surface of the tip of the building component; an avoidance portion that extends in the orthogonal direction from the portion of the base portion that protrudes beyond the abutment portion and avoids a connecting member that protrudes from the inner surface of the tip of the building component; and The problem is solved by comprising an extension portion that extends from the extending portion of the avoidance portion toward the building component and is arranged so as to sandwich the tip portion of the building component between the extension portion and the base portion, a fixing portion for fixing the measuring jig to the tip portion of the building component while the tip portion of the building component is sandwiched between the base portion and the extension portion, and a mounting portion that is provided on the base portion and extends from the base portion toward the opposite side to the abutment portion side and for placing a measuring portion of the measuring instrument, and the mounting portion is provided on the base portion so that the measurement point of the mounting portion and the abutment surface of the abutment portion correspond in the extension direction of the base portion.

[0007] With the above configuration, the measuring jig clamps and fixes the tip of the building component between the base and extension, avoiding the connecting member. Therefore, the measuring jig can be stably attached to the tip of the building component on which the connecting member is disposed. Furthermore, in the measuring jig, the measurement point of the mounting part corresponds to the contact surface of the contact part in the extension direction of the base part. Therefore, the distance from the base end to the tip of the building component can be accurately measured using the measuring tool. Therefore, the connecting member can be stably attached to the tip of the construction member on which it is disposed, allowing for easy and accurate measurements.

[0008] In this case, the measuring jig is used to read the position of the tip surface of the building component using the measuring tape, which is the measuring unit, and the avoidance unit avoids the backing metal, which is the connecting member that connects the building components together, and the end surface of the placement unit, which is the measuring point, and the abutment surface are preferably positioned at the same position in the extension direction of the base unit. With the above configuration, the measuring jig clamps and fixes the tip of the building component between the base and extension, avoiding the backing metal. Therefore, the measuring jig can be stably attached to the tip of the building component on which the backing metal is disposed. Furthermore, the end face of the mounting portion of the measuring jig corresponds to the abutment surface of the abutment portion in the extension direction of the base portion. Therefore, the distance from the base end to the tip of the building component can be measured accurately using the measuring tool.

[0009] In this case, the fixing portion is attached to one of the extension portion and the base portion, and with the tip portion of the building component and the connecting member sandwiched between the extension portion and the base portion, the measuring jig can be fixed to the tip portion of the building component and the connecting member by pressing a fixing bolt from one of the extension portion and the base portion toward the other. With the above-described configuration, the measuring jig can be easily attached to the tip of the construction component on which the backing metal is disposed.

[0010] In this case, the avoidance portion is preferably arranged at a distance from the abutment portion in the extension direction, and when the measuring jig is attached to the tip portion of the building component, a gap is formed between the avoidance portion and the connecting member in the extension direction of the base portion. With the above configuration, contact with the tip of the backing metal can be avoided, and the measuring jig can be attached to the tip of the construction component with high precision, regardless of the attachment precision of the backing metal.

[0011] In this case, the length of the abutment portion in the orthogonal direction is formed shorter than the length of the avoidance portion, and when the measuring jig is attached to the tip of the building component, a gap is formed between the abutment portion in the orthogonal direction and the connecting member. With the above configuration, contact with the outer surface of the backing metal can be avoided, and the measuring jig can be attached to the tip of the construction component with high precision, regardless of the attachment precision of the backing metal.

[0012] In this case, the measurement point of the placing portion corresponding to the contact surface of the contact portion may be an end surface on the construction member side in the extension direction. With the above configuration, the measuring part of the measuring instrument can be easily aligned by aligning the measuring part of the measuring instrument with the end face of the mounting part.

[0013] In this case, the measurement point of the placing portion corresponding to the contact surface of the contact portion may be on the end surface opposite to the surface on the construction member side in the extension direction. With the above configuration, the measuring part of the measuring instrument can be easily aligned by aligning the measuring part of the measuring instrument with the end face of the mounting part. In addition, by hooking the reference point of the measuring instrument (for example, the hook claw of a convex rule) onto the end face of the mounting part, the tip face of the building component can be used as the reference point, and the measuring instrument can measure the length from the tip to the base end of the building component.

[0014] In this case, it is preferable that a support portion extends from the protruding portion of the base portion toward the placement portion and supports the placement portion, and that a step portion is formed between the support portion and the placement portion in the extension direction. With the above configuration, the support part supports the mounting part, and the latching claw serving as the reference point can be latched onto the step part provided at a position corresponding to the tip surface of the construction component. Therefore, the strength of the mounting part can be improved, and the reference point of the measuring instrument can be easily aligned with the tip of the construction component. [Effects of the Invention]

[0015] The measuring jig of the present invention can be stably attached to the tip of a construction component on which a connecting member is provided, allowing for easy and accurate measurements. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a "measuring jig" that is used when measuring the length of a construction component using a measuring instrument, can be stably attached to the tip of a construction component on which a connecting component is arranged, and can easily measure with high accuracy.

[0018] <Measuring jig of first embodiment> As shown in FIGS. 1 to 6, the measuring jig 1 is an auxiliary jig that is used when measuring the length of a building component B with a measuring instrument M and is attached to the tip Ba of the building component B. Specifically, as shown in FIGS. 1 and 2, the measuring jig 1 is used when measuring the distance from the base end Bb to the tip end Ba of a building component B with a measuring instrument M. Below, the construction component B and the measuring instrument M will be explained first.

[0019] 1 and 2, the building component B is a component to be measured, specifically a pillar. Note that the building component B may be a beam or other component other than a pillar, or may be steel material (such as a square steel pipe) used for various purposes.

[0020] The building components B comprise a long, hollow column body B1 and a backing metal B2, which is a connecting member that connects the building components B together. In addition, an accessory member B3 is provided on the outer surface of the column body B1 so as to protrude from the outer surface. The accessory member B3 is, for example, a gusset plate, a locking member for installing a work floor that serves as temporary scaffolding, a diaphragm, a joint panel, etc., and is welded to the outer surface of the column body B1. A base plate B4 is provided at the base end Bb of the building component B. A jig T is attached to the base end surface of the base plate B4 to align the reference point of the measuring instrument M. Note that the reference point may be aligned directly to the building component B without using the jig T.

[0021] The backing metal B2 is a plate-like member for connecting and welding together building components B, and protrudes from the inner surface of the tip portion Ba of the building components B. Specifically, the backing metal B2 is disposed on the inner surface of the tip portion Ba of the building components B, and extends along the extension direction (front-to-back direction) of the building components B so as to protrude outward from the tip portion Ba. The backing metal B2 has a tapered surface. The shape of the backing metal B2 is not particularly limited and may be of various shapes. Furthermore, the backing metal B2 is not limited to a plate-shaped member for welding, but may be formed for other purposes or formed as an oblique cut portion.

[0022] As shown in FIGS. 1 and 2, the measuring instrument M is a tape measure (convex rule) that stores a measuring tape M2, which is a measuring part, in a removable manner. Specifically, the measuring instrument M includes an instrument body M1, a measuring tape M2 stored inside the instrument body M1 so as to be able to be pulled out, and a hook M3 provided at the tip of the measuring tape M2. The measuring instrument M can accurately measure the distance from the base end Bb of the building component B to the tip end Ba by hooking the hooking claw M3 onto a jig T attached to the base end Bb of the building component B. The measuring tool M is not limited to a tape measure with a hook, but may be various other measuring tools. For example, it may be a measuring tool such as a ruler with a hook, or it may be a tape measure without a hook.

[0023] 1 to 6, the measuring jig 1 is fixed to the building component B so as to sandwich the tip portion Ba of the building component B. The measuring jig 1 is used when reading the position of the tip surface of the tip portion Ba with a measuring tape M2. When the measuring jig 1 is fixed to the building component B, the contact portion 20 of the measuring jig 1 comes into contact with the tip portion Ba of the building component B. Then, as shown in Figures 3 and 4, in a top view of the measuring jig 1, the contact surface 21 of the contact portion 20 of the measuring jig 1, the measurement point of the mounting portion 60 (first end surface 61 described later), and the tip surface of the tip portion Ba are arranged at the same position in the extension direction (front-rear direction) of the base portion 10. By doing so, the distance from the base end Bb to the tip end Ba of the building component B can be measured accurately and easily using the measuring instrument M and the measuring jig 1. The reference point is not limited to the base end surface of the base plate B4 of the building member B, and the position of the reference point can be changed as appropriate.

[0024] The measuring jig 1 comprises a base portion 10 placed on the outer surface of the building component B, a contact portion 20 that contacts the tip portion Ba of the building component B, an avoidance portion 30 that avoids the backing metal B2, an extension portion 40 that clamps the tip portion Ba of the building component B between the base portion 10, a fixing portion 50 for fixing the measuring jig 1 to the building component B, and a mounting portion 60 for placing the measuring tape M2 of the measuring instrument M. It is preferable that the measuring jig 1 is made of, for example, aluminum in order to reduce its weight.

[0025] The base portion 10 is a flat plate-like member that is placed on the outer surface (side surface) of the building component B, as shown in FIGS. The base portion 10 extends along the outer surface of the building component B and is disposed so as to protrude outward (forward) than the tip end Ba of the building component B. The base portion 10 has a first portion 11 extending along the outer surface of the building component B, a second portion 12 extending from the first portion 11 and protruding forward than the tip end Ba of the building component B, and a third portion 13 extending further forward from the second portion 12 and protruding forward than the backing metal B2.

[0026] As shown in Figures 2 to 4, the abutment portion 20 is a flat plate-shaped member that extends from the protruding portion of the base portion 10 in a perpendicular direction (thickness direction, left-right direction of the base portion 10) that is perpendicular to the extension direction (front-to-back direction) of the base portion 10 and abuts against the tip surface of the tip portion Ba of the building component B. Specifically, the abutment portion 20 is a portion that protrudes from the second portion 12 of the base portion 10 along the thickness direction of the pillar main body B1. The length of the abutment portion 20 in the vertical direction is formed to be the same as the length of the base portion 10 in the vertical direction.

[0027] When the measuring jig 1 is attached to the tip Ba of the building component B, a gap is formed between the contact portion 20 and the backing metal B2 in the orthogonal direction (left-right direction). In other words, the length of the contact portion 20 in the left-right direction is formed shorter than the plate thickness of the column main body B1. In this way, by forming the contact portion 20 shorter than the plate thickness of the column body B1, it is possible to avoid contact between the contact portion 20 and the outer surface of the backing metal B2. Therefore, even if the backing metal B2 is not attached to the inside of the column body B1 with high precision, the measuring jig 1 can be attached to the tip portion Ba of the building component B with high precision.

[0028] The avoidance portion 30 is a plate-like member extending in the orthogonal direction (left-right direction) from the third portion 13 that protrudes beyond the contact portion 20 of the base portion 10. The avoidance portion 30 is provided on the base portion 10 so as to avoid the backing metal B2. The avoidance portion 30 is provided at a distance from the abutment portion 20 in the front-rear direction. Specifically, the abutment portion 20 is attached to the second portion 12, and the avoidance portion 30 is attached to the third portion 13 at a position a predetermined distance away from the abutment portion 20.

[0029] In this way, the base portion 10 is formed longer than the backing metal B2, and the avoidance portion 30 is provided at a position away from the abutment portion 20, thereby making it possible to avoid contact between the avoidance portion 30 and the tip of the backing metal B2. Therefore, even if the backing metal B2 is not attached to the inside of the column main body B1 with high precision, the measuring jig 1 can be attached to the tip portion Ba of the building component B with high precision.

[0030] The avoidance portion 30 has a pair of wall portions 31 spaced apart in the vertical direction. Specifically, the avoidance portion 30 has an upper wall portion 31a extending rightward from an upper portion of the third portion 13 of the base portion 10, and a bottom wall portion 31b extending rightward from a lower portion of the third portion 13 of the base portion 10. The upper wall portion 31a and the bottom wall portion 31b are each plate-shaped members, and connect the base portion 10 and the extension portion 40.

[0031] As shown in FIGS. 2 and 4 to 6, the extension portion 40 extends from the extension end of the avoidance portion 30 toward the building component B and is provided so as to sandwich the building component B between the extension portion 40 and the base portion 10. Specifically, the extension portion 40 is positioned between the upper wall portion 31a and the bottom wall portion 31b, and extends from the upper wall portion 31a and the bottom wall portion 31b toward the building component B, and is positioned so as to sandwich the tip portion Ba of the building component B and the backing metal B2 between the extension portion 40 and the base portion 10. The measuring jig 1 is configured so that the base portion 10, the avoidance portion 30, and the extension portion 40 form a substantially U-shape (substantially a C-shape) when viewed from above.

[0032] 5 and 6, a step is formed between the upper end 10a of the base portion 10 and the upper surface of the upper wall portion 31a. In other words, the upper portion of the base portion 10 protrudes above the upper surface of the upper wall portion 31a. By forming the step in this way, it becomes easier for the worker to grip the upper part of the base portion 10.

[0033] 4, the extension portion 40 is formed with a bolt fastening hole 41 for attaching the fixing portion 50. The bolt fastening hole 41 is a through-hole that penetrates in the left-right direction and is provided at a position that faces the first portion 11 of the base portion 10 in the left-right direction. A fixing bolt 51, which will be described later, is inserted into the bolt fastening hole 41. In this way, by providing the bolt fastening holes 41 at positions opposite to the first portion 11 of the base portion 10 in the left-right direction, the tip portion Ba of the building component B and the backing metal B2 can be sandwiched between the base portion 10 and the fixing portion 50. Therefore, the attachment strength of the measuring jig 1 to the building component B can be further increased.

[0034] 5 and 6, the measuring jig 1 has a space surrounded by the base portion 10, the pair of wall portions 31, and the extension portion 40. In this way, a worker can insert his or her fingers into this space to grasp the measuring jig 1, and therefore can hold the measuring jig 1 in one hand while operating the fixing portion 50 with the other hand to fix it to the building component B. This improves work efficiency.

[0035] As shown in Figures 2 and 4 to 6, the fixing portion 50 is intended to fix the measuring jig 1 to the tip portion Ba of the building component B while the building component B is sandwiched between the base portion 10 and the extension portion 40. The fixing part 50 is attached to the extension part 40, and with the construction member B sandwiched between the extension part 40 and the base part 10, the fixing bolt 51 is pressed from the extension part 40 towards the base part 10, thereby fixing the measuring jig 1 to the construction member B. The fixing part 50 (fixing bolt 51) is arranged between the pair of wall parts 31 in the vertical direction.

[0036] Specifically, as shown in Figures 5 and 6, the fixing portion 50 has a fixing bolt 51 that is fastened to the bolt fastening hole 41 of the extension portion 40, a handle holding portion 52 that is fixed to the head of the fixing bolt 51, and a long handle 53 that is supported by the handle holding portion 52. The fixing bolt 51 is capable of changing the length of protrusion (protrusion position) relative to the extension portion 40 by adjusting the position at which it is screwed into the bolt fastening hole 41. The handle holding portion 52 is provided on the head of the fixing bolt 51 and can hold the handle 53 in a state where it is inserted therethrough. The handle 53 extends in a direction perpendicular to the fixing bolt 51, and the fixing bolt 51 can be tightened by rotating the handle 53 up and down.

[0037] With the above configuration, as shown in FIGS. 2 and 4, by tightening the fixing bolt 51, the measuring jig 1 can be easily and firmly attached to the tip of the construction member B. At this time, the worker can efficiently perform the bolt tightening work by using the handle 53. In other words, the bolt tightening work can be performed without the need for tools.

[0038] In this embodiment, the measuring jig 1 is attached by pressing the fixing bolt 51 against the backing metal B2 to sandwich both the tip portion Ba of the building component B and the backing metal B2, but the position at which the measuring jig 1 is attached is not limited to this. For example, the measuring jig 1 may be attached by pressing the fixing bolt 51 against the inner surface of the tip portion Ba to sandwich only the tip portion Ba of the building component B.

[0039] 5 and 6, in the above configuration, fixing bolt 51 and handle 53 are integrally connected by handle holding portion 52. Specifically, after the tip of handle 53 is inserted into handle holding portion 52, a nut is fastened to the tip of handle 53. Therefore, extra attachment and removal work is not required, and the measurement jig 1 can be easily fixed to the building component B by using the integrated fixing part 50.

[0040] As shown in FIGS. 2 to 4, the placement portion 60 is provided on the base portion 10, extends toward the opposite side (outside) from the contact portion 20, and is used to place the measurement tape M2 of the measurement instrument M on it. The mounting portion 60 is a plate-like member, and is attached to the surface (outer surface) of the base portion 10 opposite to the contact portion 20. The vertical length of the mounting portion 60 is formed to be the same as the vertical length of the base portion 10. Specifically, the mounting portion 60 is provided on the outer surface of the second portion 12 of the base portion 10 and extends outward. More specifically, as shown in Fig. 1, when the hooking claw M3 is hooked onto the jig T attached to the base end Bb of the building component B to align the reference point and the measurement tape M2 is placed on the mounting surface 60a of the mounting portion 60, the measurement tape M2 extends parallel to the pillar main body B1.

[0041] In this way, since the mounting part 60 extends to a position away from the outer surface of the pillar body B1, the measuring tape M2 can be placed parallel to the pillar body B1, and therefore the length from the base plate B4 can be measured with high accuracy. Furthermore, since the mounting portion 60 extends to a position away from the outer surface of the column main body B1, interference with the accessory member B3 provided on the outer surface of the column main body B1 can be suppressed.

[0042] Note that if the base plate B4 is large, or if the accessory member B3 or the like attached to the outer surface of the building member B is large, the mounting portion 60 may be formed long. In this case, it is advisable to provide a reinforcing rib to reinforce the mounting portion 60. For example, the reinforcing rib has a triangular shape in top view and is provided so as to connect the third portion 13 of the base portion 10 and the mounting portion 60. In this way, by forming the mounting portion 60 long, a wide area can be secured for placing the measurement tape M2 in accordance with the position where the latching claws M3 are latched. In other words, the position of the measurement point of the measuring tool M can be adjusted appropriately. Furthermore, even when the mounting portion 60 is formed long, the strength of the mounting portion 60 can be increased by providing reinforcing ribs.

[0043] The mounting portion 60 is provided on the base portion 10 so that a first end surface 61 of the mounting portion 60 corresponds to the abutment surface 21 of the abutment portion 20 in the extension direction (front-rear direction) of the base portion 10. The first end surface 61 of the mounting portion 60 is the end surface (rear surface) on the building element B side in the front-rear direction. The first end surface 61 corresponds to a measurement point.

[0044] As shown in Figure 4, when viewed from above, the measuring jig 1 is arranged so that the contact surface 21 of the contact portion 20 of the measuring jig 1, the first end surface 61 of the mounting portion 60, and the tip surface of the tip portion Ba are at the same position. Therefore, when the measuring jig 1 is attached to the building component B so that the contact surface 21 of the contact portion 20 is in contact with the tip surface of the tip portion Ba, the worker can easily measure the length of the building component B by aligning it with the first end surface 61 of the mounting portion 60 and reading the scale on the measuring tape M2.

[0045] The measuring jig 1 can be easily and stably attached to the tip end Ba of the building component B on which the backing metal B2 is disposed. By using the measuring jig 1 and the measuring instrument M, the distance from the base end Bb to the tip end Ba of the building component B can be measured with high accuracy. For example, a single worker can accurately read the measurement value of the tip end Ba of the building component B. Furthermore, since both end faces of the contact portion 20 and the placement portion 60 in the front-rear direction are provided so as to correspond to each other, the measurement jig 1 can have a simple configuration.

[0046] In this embodiment, the measuring jig 1 is described as measuring the length from the base end Bb to the tip end Ba of the building component B. However, the measuring jig 1 is not limited to this, and may measure the length from the tip end Ba to the base end Bb of the building component B. In this case, the worker can measure the length of the building component B by aligning the reference point (zero point) of the measuring tape M2 with the first end surface 61 of the mounting part 60.

[0047] <Measuring jig of second embodiment> Next, a measuring jig 101 according to a second embodiment will be described with reference to FIGS. It should be noted that the description of the same contents as those of the measuring jig 1 described above will be omitted.

[0048] 7 and 8, the measuring jig 101 measures the length from the tip end Ba to the base end Bb of the building component B. The worker can measure the length of the building component B by aligning the reference point (zero point) of the latching claw M3 with the mounting part 160. The measuring tool M is a tape measure (convex rule).

[0049] The measuring jig 101 includes a base portion 110 , a contact portion 120 , an avoidance portion 130 , an extension portion 140 , a fixing portion 150 , a placement portion 160 , and a support portion 170 . The measuring jig 101 is fixed by the fixing part 150 in a state in which the tip part Ba of the building component B and the backing metal B2 are sandwiched between the base part 110 and the extension part 140.

[0050] The placing portion 160 is provided on the base portion 110, extends longitudinally toward the surface (outer surface) opposite to the contact portion 120 side, and is for latching the latching claws M3 of the measuring instrument M. The vertical length of the placement portion 160 is set to be the same as the vertical length of the base portion 110 .

[0051] The mounting portion 160 is provided on the base portion 110 so that a second end face 162 of the mounting portion 160 corresponds to the abutment surface 121 of the abutment portion 120 in the extension direction (front-rear direction) of the base portion 110. The second end face 162 of the mounting portion 160 is the end face (front surface) opposite the face on the building element B side in the front-rear direction. The second end face 162 corresponds to a measurement point.

[0052] As shown in Figure 4, when viewed from above, the measurement jig 101 is arranged so that the abutment surface 121 of the abutment portion 120 of the measurement jig 101, the second end surface 162 of the mounting portion 160, and the tip surface of the tip portion Ba are at the same position. Therefore, when the measuring jig 101 is attached to the building component B so that the abutment surface 121 of the abutment portion 120 abuts against the tip surface of the tip portion Ba, the worker can easily measure the length of the building component B by aligning the latching claw M3 with the second end surface 162 of the mounting portion 160 to set it as a reference point (zero point).

[0053] The support portion 170 is a reinforcing portion that extends from the protruding portion of the base portion 110 toward the mounting portion 160 in the orthogonal direction (left-right direction) and supports the mounting portion 160. Specifically, the support portion 170 has a rectangular shape in top view, and is provided so as to connect the third portion 113 of the base portion 110 and the second end surface 162 of the mounting portion 160. In this way, by forming the mounting portion 160 to be long, a wide area for latching the latching claws M3 can be secured. In other words, the latching position of the measuring instrument M can be adjusted appropriately. Furthermore, even when the mounting portion 160 is formed to be long, the strength of the mounting portion 160 can be increased by providing the support portion 170.

[0054] 7, a step 180 is formed between the mounting surface 160a of the mounting portion 160 and the upper end surface 170a of the support portion 170. In other words, the upper portion of the mounting portion 160 protrudes above the upper end surface 170a of the support portion 170. In this way, by forming the step portion 180, the latching claw M3 can be easily latched. Therefore, even if a backing metal B2 is disposed on the tip end Ba of the building component B, the latching claw M3 of the measuring instrument M can be hooked using the measuring jig 1 fixed to the tip end Ba of the building component B. Then, the position where the latching claw M3 is latched can be used as a reference (as the zero point position) to measure the distance from the tip end Ba of the building component B as is.

[0055] The above-described measuring jig 101 can also be easily and stably attached to the tip end Ba of the building component B on which the backing metal B2 is disposed. By using the measuring jig 101 and the measuring instrument M, the distance from the tip end Ba of the building component B can be measured with high accuracy. In this embodiment, the measuring jig 101 has been described as measuring the length from the tip end Ba to the base end Bb of the building component B. However, the measuring jig 101 is not limited to this, and may instead measure the length from the base end Bb to the tip end Ba of the building component B. In this case, the worker can measure the length of the building component B by aligning the measuring tape M2 with the second end surface 162 of the mounting part 160 and reading the scale. In this way, the measuring jig 101 can measure the length of the building component B using a plurality of methods using a convex rule.

[0056] <Other embodiments> In the above embodiment, as shown in Fig. 4, the measuring jig 1 reads the scale of the measuring tape M2 of the measuring instrument M using the first end surface 61 of the mounting portion 60 as the measurement point, but this is not limited to this. For example, the mounting portion 60 may be arranged so as to straddle the contact surface 21 of the contact portion 20 in the front-to-rear direction, and a mark (measurement point) may be provided on the mounting surface 60a at a position corresponding to the contact surface 21. In this way, the worker can measure the length of the building component B by aligning the scale of the measuring tape M2 with the mark on the mounting surface 60a.

[0057] In the above embodiment, as shown in FIG. 2, the measuring jig 1 is fixed to the building component B by the fixing bolt 51, but the fixing means by the fixing part 50 can be changed as appropriate. For example, instead of the fixing bolt 51, the measuring jig 1 may be fixed to the construction component B using a clamping member (a clamping member that can be attached and detached with one touch) or the like.

[0058] In the above embodiment, the measuring jig according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof. In particular, the above-described embodiments are merely examples and do not limit the present invention. [Explanation of symbols]
