Description

  The present invention relates to a dimension measuring jig used for eaves-laying construction.

  Conventionally, in an eaves arrangement installation work, a dimension measurement operation such as measuring between eaves eaves is frequently performed. For example, in order to arrange eaves along the eaves of the roof, the eaves made to a certain length at the eaves manufacturing factory are connected in series along the eaves of the roof. Since the length dimension in the eaves direction is not necessarily a multiple of the eaves of a certain length, the last eaves connected in sequence are cut as appropriate, and the length dimension of the eaves to be cut Is determined by dimensional measurements at the construction site. Specifically, as shown in FIG. 5, the dimension measuring operation is performed by the scale D of the tape measure B at the end portion 10b in the length direction of the eaves rod 10 that is already attached to the eaves 16 by the operator D climbing the stepladder 15 or the like. The operator E who climbs the stepladder 15 or the like reads the scale of the scale band 12 at a predetermined position while holding the end of the band 12 together. As described above, the dimension measurement work in the eaves-laying construction usually requires two installers D and E, the installer D holding the tip of the tape measure B and the installer E reading the scale of the tape measure B at the same time. It was a cumbersome work. Therefore, it has been eagerly desired that the dimension measuring work in the eaves-laying construction can be facilitated by reducing the number of required installers.

By the way, a suction cup is attached to the tip of the tape measure scale band as in Patent Document 1, or a permanent magnet is attached to the tip of the tape measure scale band as in Patent Document 2, and the tip of the tape measure scale band is attached to the object to be measured. There are things that are going to be fixed, and it is conceivable to use this special tape measure to perform the dimension measurement work in the eaves ridge arrangement construction, but use a tape measure that is dedicated to eave ridge arrangement construction. Is not preferable in terms of cost, and the eaves are generally composed of a thin plate wall made of resin, and the eaves have a curved wall surface like a round eave In many cases, the above suction cups and permanent magnets cannot hold the tip of the tape measure graduation band at the end of the eaves, which is difficult to employ for the dimension measurement work in the eaves installation.

The tip of the scale band 12 can be fixed to the end of the object C to be measured by inserting the hook 11 at the tip of the scale band 12 and hooking and engaging with the hole edge portion of the through-hole 4. Therefore, in the dimension measurement work from the end of the object to be measured C, the installer D for holding and fixing the tip of the scale band 12 of the tape measure B required to the end of the object to be measured C becomes unnecessary. The work can be performed by only one installer E who reads the scale 13 of the tape measure B, thus facilitating the work. Than it is achieved. Moreover, according to this dimension measuring jig A, it is possible to perform the dimension measuring work using a commercially available general tape measure B instead of a dedicated product, that is, the conventional tape measure B is continuously used. By simply introducing the dimension measuring jig A above, it is possible to facilitate the dimension measuring operation. Further, according to the dimension measuring jig A, the end of the measuring object C is brought into contact with the contact part 3, so that the tip of the scale band 12 of the tape measure B locked in the through hole 4 and the measuring object C Therefore, the distance from the end portion of the substrate can be kept constant, and the accuracy of dimensional measurement can be ensured.

Insert a fitting part that attaches the jig body to the object to be measured, an abutting part that abuts the end of the object to be measured sandwiched between the attachment parts, and an L-shaped hook at the tip of the tape measure scale band. If the eave ridge composed mainly of a thin plate wall is the object to be measured, that is, the end of the eave ridge in the longitudinal direction in the eave ridge arrangement construction In the dimension measurement work from, regardless of the shape of the eaves rod, the tip of the tape measure scale band can be fixed by a dimension measurement jig attached to the longitudinal end of the eaves rod, that is, conventionally required. This eliminates the need for a contractor to hold and fix the tip of the tape measure scale band to the longitudinal end of the eaves. Furthermore, it is possible to attach the dimension measuring jig to the longitudinal end of the eaves in a predetermined state by bringing the longitudinal end of the eaves into contact with the abutment. Therefore, regardless of the shape of the eaves, while maintaining the accuracy of dimensional measurement, it can be performed by only one contractor who reads the scale, and the dimensional measurement work can be facilitated. Have.

  As shown in FIG. 2, the dimension measuring jig A of this example is suitable for measuring the dimensional distance from the longitudinal end portion 10 b of the eaves 10 formed mainly by the thin plate wall 10 a using the tape measure B. A mounting part 2 for mounting the jig body 1 to the measured object C by sandwiching a plate-like part at the end of the measured object C such as the eaves 10 between the front and back, and a mounting part 2, the abutting portion 3 for abutting the end portion of the object C to be measured sandwiched between 2 and the L-shaped hook 11 at the tip of the scale band 12 of the tape measure B is inserted and hooked and locked to the hole edge portion. A through hole 4 is provided.

  Specifically, the jig body 1 constituting the main body of the dimension measuring jig A is formed in an L-shaped plate shape in which the main piece 1a and the sub piece 1b are orthogonal to each other. For convenience, the opposing direction of the main piece 1a and the sub piece 1b will be described as an inward direction, and the opposite will be described as an outward direction. The main piece 1a of the jig body 1 is cut into a U-shape when viewed from above, and a spring piece 5 is formed at a portion surrounded by the cut 6. Specifically, the U-shaped cut 6 in a top view is formed to be parallel to each outer edge other than the outer edge on the sub-piece 1b side in the rectangular outer edge of the main piece 1a. The spring piece 5 is formed in a shape that rises substantially perpendicularly from the outer surface of the main piece 1a, then bends away from the sub-piece 1b, and extends so as to follow the outer surface of the main piece 1a. . In other words, the base end portion 5b of the spring piece 5 is formed so as to rise substantially perpendicularly from the outer surface of the main piece 1a, and the tip end portion 5a of the spring piece 5 extends in the opposite direction of the sub piece 1b and is also the main piece 1a. It is formed so as to be close to the outer surface. Here, the mounting portion 2 is composed of the outer surface of the opposing main piece 1 a and the tip portion 5 a of the spring piece 5, and the contact portion 3 is composed of the base end portion 5 b of the spring piece 5. Yes. Specifically, a peak portion 8 is formed at the tip portion 5a of the spring piece 5 so as to bring the spring piece 5 close to the outer surface of the main piece 1a. A guide portion 7 is formed such that the piece 5 is separated from the outer surface of the main piece 1a. This guide part 7 makes it easy to introduce the device under test C (eave bar 10) into the mounting part 2. Further, a through hole 4 penetrating inward and outward is formed in the sub-piece 1b of the jig body 1. Specifically, the through hole 4 is formed in a rectangular shape that is long in the width direction of the jig body 1.

  Here, since the dimension measuring jig A of the present example has the above-described configuration, the jig body 1 is formed by bending the plate material at a right angle, and the main piece 1a of the jig body 1 is cut and raised. The spring piece 5 is formed, and the mounting portion 2 and the contact portion 3 are formed by applying the spring piece 5 in a predetermined shape, and the through-hole 4 is drilled in the sub-piece 1b of the jig main body 1. It has been made possible. That is, the dimension measuring jig A has a simple configuration, can be formed from a single plate material, and ensures easy manufacturability.

  In order to measure the distance dimension from the end portion 10b in the longitudinal direction of the eaves rod 10 using this dimension measuring jig A, the dimension measuring jig A is attached to the eaves by the mounting portion 2 as shown in FIGS. The L-shaped hook 11 at the tip of the scale band 12 of the tape measure B is inserted into the through hole 4 of the dimension measuring jig A and the edge portion of the through hole 4 is attached to the longitudinal end 10b of the flange 10. By hooking and locking the hook 11, the tip of the scale band 12 of the tape measure B can be fixed to the end portion 10 b in the longitudinal direction of the eaves rod 10. That is, in the dimension measuring operation from the longitudinal end portion 10b of the eaves rod 10 using the dimension measuring jig A, the tip of the scale band 12 of the tape measure B that has been conventionally required is attached to the object C to be measured. It is possible to eliminate the need for a contractor to be held and fixed to the end, and as shown in FIG. 4, it can be performed by only one contractor who reads the scale 13 of the tape measure B, thereby facilitating the dimension measurement work. -ing In addition, since the dimension measurement operation | work from the edge part 10b of the longitudinal direction of the eaves rod 10 is frequently performed at the time of the eaves rod arrangement | positioning construction performed in a high place, by easiness of this dimension measurement operation | work, The efficiency of installation and construction can be greatly improved.

  Here, the dimension measuring jig A is attached to the longitudinal end portion 10b of the eaves rod 10 by the mounting portion 2 that sandwiches a plate-like portion such as a thin plate wall 10a constituting the eaves rod 10 between the front and back. Is called. Specifically, the gap between the tip 5a of the spring piece 5 constituting the mounting portion 2 and the outer surface of the jig body 1 is at least larger than the thickness of the thin plate wall 10a constituting the eaves 10 in a natural state where nothing is sandwiched. It is narrowly formed. Further, when the eaves rod 10 is inserted into the gap between the tip 5a of the spring piece 5 and the outer surface of the jig body 1, the eave ridge 10 into the gap is guided by the guide portion 7 of the tip 5c of the spring piece 5. It has been made possible to insert smoothly. When the eaves rod 10 is inserted into the gap, the end portion 10b of the eave rod 10 hits the peak portion 8 of the spring piece 5, and the spring piece 5 receives the insertion pressure of the eave rod 10 at this peak portion 8. It will naturally bend outward. The spring piece 5 that has been deflected to the outside under the insertion pressure of the eaves rod 10 is elastically restored. Due to this elastic restoration, the eaves rod 10 is firmly fixed between the tip 5a of the spring piece 5 and the outer surface of the jig body 1. It will be sandwiched between the front and back. More specifically, since the eaves rod 10 is clamped by the mounting portion 2 so as to concentrate the clamping pressure on the protruding tip portion of the peak portion 8 of the spring piece 5, the mounting portion 2 can firmly clamp the eave rod 10 It is. Since the main body of the eaves 10 is generally composed of a thin plate wall 10a, according to the mounting portion 2 that sandwiches the plate-shaped portion, the eaves can be used regardless of the shape of the square or round eaves 10. The dimension measuring jig A can be attached and fixed to the end portion 10b of the flange 10 in the longitudinal direction.

  Moreover, in the dimension measurement work from the longitudinal end 10b of the eaves rod 10 using this dimension measurement jig A, the work is performed using a commercially available general tape measure B, not a dedicated product. Can do. In other words, the tape measure B that has been used in the past can be used in parallel with the dimension measuring jig A, and the dimension measuring work can be facilitated simply by introducing the dimension measuring jig A after the tape measure B is continuously used. It can be planned. Further, in the dimension measurement work from the longitudinal end portion 10b of the eaves rod 10 using the dimension measuring jig A, the elongate end portion 10b of the eaves rod 10 is inserted deeply into the mounting portion 2, The longitudinal end portion 10b of the flange 10 is brought into contact with the contact portion 3 which is the base end portion 5b of the spring piece 5. The longitudinal end portion 10b of the eaves rod 10 is used as the contact portion 3. By abutting, the distance between the tip of the scale band 12 of the tape measure B locked to the through hole 4 and the end portion 10b in the longitudinal direction of the eaves rod 10 can be kept constant, that is, the tape measure B When the scale 13 is read, it is only necessary to take into account the deviation between the contact portion 3 and the through-hole 4 which is a constant value, so that the accuracy of dimension measurement can be ensured.

  Although not shown, of course, the contact portion 3 and the through hole 4 are formed so as to be in the same position in the length direction of the scale band 12, and the scale of the scale band 12 of the tape measure B that is locked to the through hole 4. The dimension measuring jig A in which the zero point of 13 coincides with the contact portion 3 is also preferable. According to this, the scale 13 of the tape measure B directly indicates the distance from the end of the object C to be measured, and the convenience of dimension measurement can be improved.

  As described above, the dimension measuring jig A of the present example enables the attachment portion 2 to be attached to the longitudinal end portion 10b of the eaves rod 10 regardless of the shape of the eaves rod 10, The contact portion 3 can ensure the accuracy of the dimension measurement, and the tape measure B used for the dimension measurement can be a commercially available general one, and the dimension measuring jig A can be used. Since the tip of the scale band 12 of the tape measure B can be fixed to the end portion 10b of the eaves rod 10 in the longitudinal direction, the dimensional measurement operation is performed by the installer E who reads the scale 13 of the tape measure B only by introducing the dimension measurement jig A. In the dimension measurement work in the eaves laying construction that can be performed only at high places where the scaffolding is poor, the work can be facilitated particularly. In the above description, the case where the dimension measuring jig A is used for the dimension measuring work from the end portion 10b in the longitudinal direction of the eaves rod 10 is described. However, the mounting portion 2 is a plate-like shape at the end portion of the object C to be measured. Since the part is sandwiched, it goes without saying that the dimension measuring jig A can be used for the object C to be measured other than the eaves bowl 10 so as to exhibit the above-described effect.

It is a perspective view which shows the use condition of the dimension measurement jig | tool of the example of embodiment of this invention. It is a dimension measuring jig same as the above, (a) is a front view, (b) is a side view, and (c) is a top view.
