Description

[Technical field]

[0001] The present invention relates to a measuring jig, and more particularly to a measuring jig used when measuring a construction member with a measuring instrument. [Background technology]

[0002] 2. Description of the Related Art Conventionally, in the field of construction and the like, a groove is prepared at the tip of a steel material (construction component) and the steel materials (construction components) are welded together. If no bevel preparation is performed on the tip of the steel material, the distance from the tip of the steel material can be measured using a measuring tool (e.g., a tape measure). Specifically, the total length of the steel material can be measured by hooking a hook provided on the tip of the measuring tool onto the end face (corner of the end face) of the steel material. On the other hand, when a groove is made on the tip of the steel material, it is difficult to measure the distance from the tip of the steel material using a measuring tool. Specifically, an oblique cut is formed on the end face of the steel material, so the hook of the measuring tool cannot be hooked. Therefore, in the latter case, measurements were performed by attaching an angle iron (L-shaped angle) to the end face of the steel material and supporting the measuring tape of the measuring tool on the angle iron. [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] In the measurement work using angle irons as described above, the angle irons themselves are heavy, and it takes two people to attach the angle irons, making the measurement work difficult. Also, if the dimensional accuracy of the angle irons is poor, the measured values ​​of the steel material may be off. Although a measurement auxiliary tool such as that disclosed in Patent Document 1 has been proposed, there is a risk that even this measurement auxiliary tool cannot be stably attached to the tip of the steel material.

[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 is used when measuring building components with a measuring instrument and can be attached more stably to the tip of the building component than conventional measuring tools. Another object of the present invention is to provide a measuring jig that can be stably and easily attached to the tip of a building component that has been beveled. [Means for solving the problem]

[0006] The above problem is solved by the measuring jig of the present invention, which is used when measuring a building component with a measuring instrument and is attached to the tip of the building component, and the measuring jig is used when measuring a distance from a groove formed at the tip of the building component, and includes a base portion that is placed on the outer surface of the building component and 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 a direction perpendicular to the extension direction of the base portion and abuts against the end face of the groove of the building component, and a contact portion that contacts the end face of the groove of the building component from the extending portion of the contact portion. The problem is solved by comprising an extension portion that extends toward a construction component and is positioned so as to sandwich the tip of the construction component between the extension portion and the base portion, a hanging portion that is provided on the side of the base portion opposite the abutment portion and is capable of hanging a hanging portion provided at the tip of the measuring tool, and a fixing portion for fixing the measuring jig to the tip of the construction component with the tip of the construction component sandwiched between the base portion and the extension portion, and the hanging portion is provided on the base portion such that an end face of the hanging portion corresponds to the abutment surface of the abutment portion in the extension direction of the base portion.

[0007] With the above configuration, it is possible to realize a measuring jig that can be stably attached to the tip of a building component that has undergone groove preparation. In detail, the measuring jig has a fixing portion for fixing the measuring jig to the tip of the building component in a state where the tip of the building component is sandwiched between the base portion and the extension portion. This allows the measuring jig to be stably attached to the tip of the building component that has been subjected to groove processing. The measuring tool includes a base portion, a contact portion that contacts the end face of the groove of the building component, and a hook portion that can hook the tip of the measuring tool, and the end face of the hook portion corresponds to the contact surface of the hook portion in the extending direction of the base portion. This allows the measuring tool to measure the distance from the groove formed at the tip of the building component.

[0008] In this case, the measuring jig is used when measuring the building component using the measuring instrument which stores a measuring tape in a removable manner, and the hanging portion protrudes from the base portion toward the opposite side to the abutment portion and is capable of hanging a hanging claw provided at the tip of the measuring tape of the measuring instrument, and the hanging portion is preferably provided on the base portion so that the end face of the hanging portion and the abutment surface of the abutment portion are in the same position in the extension direction of the base portion. With the above configuration, the hook claw provided at the tip of the measuring tool can be appropriately hooked, and the distance from the groove of the building component can be appropriately measured using the measuring jig.

[0009] In this case, the fixing portion is attached to one of the extension portion and the base portion, and with the tip of the building component clamped between the extension portion and the base portion, the measuring jig is fixed to the tip of the building component by pressing a fixing bolt from one of the extension portion and the base portion to the other. With the above configuration, it is possible to realize a measuring jig that can be easily attached to the tip of a building component that has undergone groove preparation.

[0010] In this case, the hanging portion has a hanging body that protrudes from the base portion toward the side opposite the abutment portion and extends longitudinally in a direction intersecting the extension direction of the base portion, and a through hole that is formed on a surface of the hanging body in the extension direction of the base portion and passes through the hanging body, and it is preferable that the hanging portion provided at the tip of the measuring instrument is hooked onto the edge of the through hole. By hooking the hooked portion (hook) at the tip of the measuring tool onto the edge of the through hole of the hook portion, it is possible to prevent the hook from coming off (falling off).

[0011] In this case, the through hole has an elongated hole shape and extends longitudinally in a direction intersecting the extension direction of the base portion, and the edge portion of the through hole that hooks the hooked portion extends along the longitudinal direction of the through hole. With the above configuration, a relatively long edge portion for hooking the hooked portion (hooking claw) can be secured. In other words, a wide area can be secured for hooking the hook of the measuring tool on the measuring jig (hooking position can be adjusted). Therefore, even if ribs or the like are formed on the outer surface of the building component, the measuring tool can be positioned so as to cross the rib.

[0012] In this case, the abutment portion extends from the protruding portion of the base portion in a direction perpendicular to the extending direction of the base portion at a predetermined interval and has left and right abutment wall portions that abut against the end faces of the groove of the building component, and a connecting wall portion that connects the extending ends of the left and right abutment wall portions, and the left and right abutment wall portions each abut against the end faces of the groove of the building component, the extending portions extend from the connecting wall portions toward the building component and are positioned so as to sandwich the tip end of the building component between the base portion, and the fixing portion is positioned between the left and right abutment wall portions. As described above, since the left and right abutment walls abut the end faces of the groove of the building component and the fixing part is disposed between the left and right abutment walls, the measuring tool can be stably attached to the tip of the building component. As a result, the distance from the groove of the building component can be measured with high accuracy. Effect of the Invention

[0013] The measuring jig of the present invention is used when measuring a building component with a measuring instrument, and can be attached to the tip of the building component more stably than ever before. Furthermore, it can be stably and easily attached to the tip of a construction component that has been beveled. [Brief description of the drawings]

[Figure 7] FIG. 11 is a perspective view of a measurement jig, a construction member, and a measurement instrument according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] 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 building components using a measuring instrument and enables stable attachment to the tip of a building component that has undergone groove preparation.

[0016] <Measurement jig according to the first embodiment> As shown in Figs. 1 to 6, the measuring jig 1 is an auxiliary jig that is used when measuring a building component B with a measuring instrument M and is attached to the tip of the building component B. Specifically, the measuring jig 1 is used when measuring the distance from a groove B3 formed at the tip of a building component B by a measuring tool M, as shown in Figs. Below, the construction component B and the measuring instrument M will be explained first.

[0017] 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. The building component B comprises a long hollow column body B1 and a diaphragm B2 fixed to the outer surface of the column body B1. The outer surface of the column body B1 is provided with connecting parts and ribs protruding from the outer surface. A beam is connected to the diaphragm B2. At the tip of the building component B, a groove B3 is formed for welding the building components together. The groove B3 is formed as an oblique cut as shown in Fig. 2, but the shape of the groove B3 is not particularly limited and may be a groove of various shapes. In addition, the groove is not limited to a groove for welding, and may be a groove or depression formed for other purposes, or a chamfered groove.

[0018] As shown in Figs. 1 and 2, the measuring tool M is a tape measure (convex rule) that stores a measuring tape M2 in a removable manner. Specifically, the measurement tool M includes a tool body M1, a measurement tape M2 stored inside the tool body M1 so as to be able to be pulled out, and a hooking claw M3 (hooked portion) provided at the tip of the measurement tape M2. The measuring tool M can accurately measure the distance from the groove B3 of the building component B by hooking the hook claw M3 onto the measuring jig 1 (hook portion 20) attached to the tip of the building component B. The measuring tool M is not limited to a tape measure, and may be various measuring tools. For example, it may be a measuring tool such as a ruler having a hook. In other words, it may be a measuring tool having a hook part.

[0019] As shown in Figs. 1 to 6, the measuring jig 1 is fixed to the building component B in such a way that the leading end of the building component B is sandwiched between the measuring jig 1 and the building component B. When the measuring jig 1 is fixed to the building component B, the contact portion 30 of the measuring jig 1 contacts the groove B3 of the building component B. Then, as shown in Fig. 3 and Fig. 4, in a side view of the measuring jig 1, the measuring jig 1 is positioned so that the end face 23 of the latch portion 20 of the measuring jig 1 and the end face of the groove B3 are in the same position. In this way, the distance from the groove B3 of the building component B can be measured easily and accurately using the measuring tool M and the measuring jig 1. In order to reduce the weight, the measurement jig 1 is preferably made of aluminum, for example.

[0020] Specifically, the measuring jig 1 comprises a base portion 10 placed on the outer surface of the building component B, a hanging portion 20 capable of hanging the measuring tool M (hanging claw M3), a contact portion 30 that abuts the groove B3 of the building component B, an extension portion 40 that clamps the tip of the building component B between the base portion 10, and a fixing portion 50 for fixing the measuring jig 1 to the building component B.

[0021] The base portion 10 is a flat plate-like member placed on the outer surface (upper surface) of the building component B, as shown in FIGS. The base portion 10 is disposed so as to extend along the outer surface of the building component B and protrude outward beyond the tip end of the building component B.

[0022] As shown in Figures 2 to 4, the hook portion 20 is provided on the surface (upper surface) of the base portion 10 opposite the abutment portion 30 side, and hooks a hook claw M3 provided at the tip of the measurement tape M2 of the measurement instrument M. The hanging portion 20 has a hanging body 21 that protrudes upward from the base portion 10 and extends longitudinally in a direction intersecting the extension direction of the base portion 10 (the width direction of the base portion 10), and a through hole 22 that is formed on a surface of the hanging body 21 in the extension direction of the base portion 10 and penetrates the hanging body 21. A latching claw M3 provided at the tip of the measuring tool M is latched onto the edge of the through hole 22.

[0023] As shown in Figures 3 and 4, the hook portion 20 is positioned on the base portion 10 so that the end face 23 of the hook body 21 and the abutment surface 33 of the abutment portion 30 are in the same position in the extension direction of the base portion 10. Therefore, even if the building component B has been grooved, the hook claw M3 of the measuring tool M can be hooked using the measuring jig 1 fixed to the tip of the building component B. Then, the position where the hook claw M3 is hooked can be used as a reference (as a zero point position) to measure the distance from the groove B3 of the building component B.

[0024] The hook body 21 extends elongated in the width direction of the measurement jig 1, as shown in FIGS. The through hole 22 has an elongated hole shape and similarly extends long in the width direction of the measurement jig 1. That is, in the through hole 22, an edge portion 22a that hooks the hook claw M3 extends along the long direction of the through hole 22. Therefore, a wide area of ​​the edge portion 22a for latching the latching claw M3 can be secured, which means that the latching position of the measuring tool M can be adjusted appropriately. By doing so, even if ribs or the like are attached to the outer surface of the building component B, as shown in Figure 1, the measuring device M can be extended in the width direction of the building component B so as to cross the ribs.

[0025] In the above configuration, as shown in Figures 1 and 2, when the hook M3 of the measuring tool M is hooked to the hook portion 20, the measuring tool M (measurement tape M2) is disposed at a position slightly higher than the building component B. In other words, a gap is formed between the outer surface of the building component B and the measuring tool M. By doing so, even if a diaphragm B2, ribs, etc. are attached to the outer surface of the building component B, the measuring device M can be extended in the height direction (thickness direction) of the building component B so as to cross the diaphragm B2 or ribs.

[0026] As shown in Figures 2 to 4, the abutment portion 30 extends from the protruding portion of the base portion 10 in a direction perpendicular to the extension direction of the base portion 10 (downward of the base portion 10) and abuts against the end face of the groove B3 of the building component B. Specifically, the abutment portion 30 extends downward from the protruding portion of the base portion 10 at a distance in the width direction of the base portion 10 and has left and right abutment wall portions 31 that abut against the end faces of the groove B3 of the building component B, and a connecting wall portion 32 that connects the extending ends of the left and right abutment wall portions 31. The left and right contact walls 31 contact the end faces of the groove B3 of the building component B, respectively.

[0027] The left and right contact wall portions 31 are disposed so as to sandwich the hook portion 20 therebetween when viewed from the front or rear of the measurement jig 1. Alternatively, the left and right contact wall portions 31 are disposed at positions corresponding to both ends of the hook portion 20 in the longitudinal direction. The measuring jig 1 is configured so that the base portion 10, the left and right abutting wall portions 31, and the connecting wall portion 32 form a closed cross-sectional shape (a frame-like cross-sectional shape) when viewed from the front or rear. 3 and 4, the protruding end of the base portion 10 protrudes further outward than the contact portion 30. An operator can easily grip the measurement jig 1 by utilizing the protruding portion.

[0028] As shown in Figs. 2 and 4 to 6, the extension portion 40 extends from the extension end of the contact portion 30 toward the building component B and is provided so as to sandwich the building component B between the base portion 10 and the extension portion 40. Specifically, the extension portion 40 extends from the connecting wall portion 32 toward the building component B, and is disposed so as to sandwich the tip end of the building component B between the extension portion 40 and the base portion 10. The measurement jig 1 is configured such that the base portion 10, the contact portion 30, and the extension portion 40 form a substantially U-shape (substantially C-shape) in side view. As shown in FIG. 6, a bolt fastening hole 41 for attaching the fixing part 50 is formed in the bottom surface of the extension part 40.

[0029] As shown in Figures 2 and 4 to 6, the fixing portion 50 is intended to fix the measuring jig 1 to the tip of the construction component B with the construction component B sandwiched between the base portion 10 and the extension portion 40. The fixing portion 50 is attached to the extension portion 40, and with the building component B sandwiched between the extension portion 40 and the base portion 10, the fixing bolt 51 is pressed from the extension portion 40 toward the base portion 10, thereby fixing the measuring jig 1 to the building component B. The fixing portion 50 (fixing bolt 51 ) is disposed between the left and right contact wall portions 31 .

[0030] Specifically, as shown in Figures 5 and 6, the fixing portion 50 has a fixing bolt 51 fastened to the bolt fastening hole 41 of the extension portion 40, a handle holding portion 52 fixed to the head of the fixing bolt 51, and a long handle 53 supported by the handle holding portion 52. The fixing bolt 51 is capable of changing the protruding length (protruding position) with respect to the extending portion 40 by adjusting the screwing position with respect to the bolt fastening hole 41. The handle holding portion 52 is provided on the head of the fixing bolt 51 and is capable of holding the handle 53 in a state in which the handle 53 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 horizontally.

[0031] With the above configuration, as shown in Figs. 2 and 4, the measuring jig 1 can be easily and firmly attached to the tip of the building component B by tightening the fixing bolt 51. 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. In addition, when the thickness of the tip portion of the building component B is relatively thin, by sandwiching a support plate between the base portion 10 and the extension portion 40, the building component B can be easily sandwiched.

[0032] 5 and 6, in the above configuration, the fixing bolt 51 and the handle 53 are integrally connected by the handle holding portion 52. Specifically, after the tip of the handle 53 is inserted into the handle holding portion 52, a nut is fastened to the tip of the 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 utilizing the integrated fixing part 50.

[0033] The measuring jig 1 can be easily and stably attached to the tip of the building component B after groove preparation. By using the measuring jig 1 and the measuring instrument M, the distance from the groove of the building component B can be measured with high accuracy. For example, a single worker can measure the distance from the groove of construction component B. The measuring jig 1 may be used to measure the dimensions of building components such as beams and steel materials used for various purposes, in addition to measuring the dimensions of columns. The measuring jig 1 is not limited to measuring the dimensions of finished products such as columns and beams, but can also be used for marking work to determine the mounting positions of intermediate parts such as columns and beams, and can also be used for measuring the dimensions and marking work of materials before docking.

[0034] <Measurement jig according to the second embodiment> Next, a measuring jig 101 according to a second embodiment will be described with reference to FIG. It should be noted that the description overlapping with that of the measuring jig 1 described above will be omitted.

[0035] The building component B is a beam as shown in Fig. 7. A groove B3 is formed at the tip of the flange of the building component B (beam). The measuring instrument M is a tape measure (convex rule).

[0036] The measurement jig 101 includes a base portion 110 , a first latch portion 120 , a second latch portion 125 , a contact portion 130 , an extension portion 140 , and a fixing portion 150 . The measuring jig 101 is fixed by a fixing part 150 in a state in which the tip part of the construction member B is sandwiched between the base part 110 and the extending part 140 .

[0037] The first latch portion 120 is a latch protrusion that protrudes upward from the upper surface of the base portion 110 and extends elongated in the width direction of the base portion 110. The first latch portion 120 has an edge portion 121 for latching the latch claw M3 of the measuring instrument M. The second hook portion 125 is a hook recess (hook groove) recessed downward from the upper surface of the base portion 110, and extends elongated in the width direction of the base portion 110. The second hook portion 125 may be a through hook hole. The second latch portion 125 has an edge portion 126 for latching the latch claw M3 of the measuring instrument M.

[0038] The first hook portion 120 and the second hook portion 125 are disposed at different positions in the width direction of the base portion. In a side view of the measurement jig 101, the end face of the edge portion 121 of the first hook portion 120, the end face of the edge portion 126 of the second hook portion 125, and the abutment surface of the abutment portion 130 are positioned in the same position (overlapping position).

[0039] The measuring jig 101 can be easily and stably attached to the tip of the building component B after groove preparation. By using the measuring jig 1 and the measuring instrument M, the distance from the groove of the building component B can be measured with high accuracy.

[0040] Furthermore, with the measuring jig 101, the measuring tool M can be hung by selectively using the first hook portion 120 and the second hook portion 125 depending on the type and shape of the building component B. For example, as shown in Fig. 7, when the building component B is a beam, it is advisable to hang the measuring tool M on the second hooking portion 125. The reason for this is that since generally no protrusions such as ribs are formed on the top surface of a beam, there is no need to cross ribs in the height direction (thickness direction) of the beam, and the measuring tool M can be extended. By minimizing the gap (gap in the height direction) between the building component B (beam) and the measuring tool M (measuring tape M2), it is possible to suppress vibration and accurately measure the distance from the groove of the building component B (beam). The measuring jig 101 may be used to measure the dimensions of building components such as pillars, and steel materials used for various purposes, in addition to being used to measure the dimensions of beams.

[0041] <Other embodiments> In the above embodiment, as shown in FIG. 2, the measurement jig 1 is provided with a hook portion 20 for hooking the hook claw M3 of the measurement instrument M, but the shape and configuration of the hook portion 20 are not particularly limited and can be changed. For example, as shown in Fig. 7, the hooking portion 20 may be a hooking protrusion having a simple shape, or may be a hooking recess. Alternatively, the hooking portion 20 may have only a hooking recess. It is sufficient that the hooking portion has a shape that allows the hooking portion of the measuring tool M to be hooked.

[0042] In the above embodiment, as shown in FIG. 4, the hook portion 20 is provided on the base portion 10 so that the end face 23 of the hook portion 20 and the abutment surface 33 of the abutment portion 30 are in the same position in the extension direction of the base portion 10. On the other hand, the end face 23 of the hook portion 20 and the abutment surface 33 of the abutment portion 30 may be spaced apart by a preset distance. Even in such a case, the distance from the groove B3 of the building component B can be calculated by correcting the distance by which the end face 23 and the abutment surface 33 are shifted. In other words, it is sufficient that the end face 23 of the hook portion 20 and the abutment surface 33 of the abutment portion 30 are disposed in corresponding positions (they do not necessarily have to be disposed in the same position).

[0043] 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, the measuring jig 1 may be fixed to the building component B using a clamp member (a clamp member that can be attached and detached with one touch) instead of the fixing bolt 51.

[0044] 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 is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof. In particular, the above-described embodiment is merely an example and does not limit the present invention. [Explanation of symbols]
