Description

The present invention relates to a jig unit, and particularly to a jig unit used when measuring the distance between opposing corners of a frame that constitutes a building frame using a laser measuring device.

BACKGROUND ART Conventionally, the diagonal dimensions of the outer shape of frames and the like and the diagonal dimensions of openings used in so-called system architecture constructed using standardized structural members have been measured using a tape measure (convex).

However, when a single person performs measurements using a convex, it is necessary to move the convex claws to the corners of the frame and then move to the opposite corner to perform the measurement. At that time, there was a problem in that the hooks of the convex may come off while being hooked onto the corners of the frame and moved, requiring redoing. Furthermore, when measuring the diagonal dimension of the opening, the convex claw cannot be hung on the frame. Therefore, in order to avoid these problems, it was necessary for two people to perform the measurements.

In addition, if the material at the part where the diagonal is to be measured is warped, if the diagonal dimension is long and the convex tape bends, or if the convex tape cannot be stretched due to the influence of wind when measuring outdoors. In such cases, it is difficult to measure accurately using a convex device, and there are also problems in that measurements vary depending on the operator.

Furthermore, when a plurality of frames are stacked and placed, the top frame has a height of about 1.6 to 2.0 m, making it difficult to measure using a convex. Furthermore, it was difficult to measure using a convex when there was no space on all sides of the frame for people to pass through.

At construction sites, laser measuring devices are used to measure distances, but the diagonal dimensions of frames have not been measured using laser measuring devices.

The present invention has been made in view of the above problems, and its purpose is to easily and accurately measure the distance between opposing corners of a frame using a laser measuring device. The purpose of the present invention is to provide a jig unit.

<<About the jig unit according to one embodiment of the present invention>>
Hereinafter, one embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to the accompanying drawings.
In addition, in the drawings, each member is illustrated in a somewhat simplified and schematic manner to make the explanation easier to understand. Further, the sizes (dimensions) of each member shown in the drawings, the intervals between members, etc. are also different from the actual ones.

Further, in the following description, measurement of the diagonal dimensions of a frame used in system architecture in which members constituting buildings such as factories, warehouses, distribution facilities, store buildings, etc. are standardized and systemized will be explained. However, the present invention is also applicable to frames constituting buildings other than system architecture.

FIG. 1 is a perspective view showing an example of a jig unit of the present invention.
As shown in FIG. 1, the jig unit 10 of the present invention includes a first jig 12 and a second jig 30. The jig unit 10 of the present invention has a diagonal dimension between opposing corners of the outer shape of a frame 100 constituting a building frame, and a diagonal dimension between opposing corners of an opening 110 of the frame 100, as shown in a plan view in FIG. This is a jig unit for measuring the diagonal dimension between corners using a laser measuring device. As shown in FIG. 2, the diagonal dimensions between opposing corners of the outer shape of the frame 100 are the distance c1 between the corner 102 and the corner 104, and the distance c1 between the corner 106 and the corner 108. The distance is c2. Further, the diagonal dimensions between opposing corners of the opening 110 of the frame 100 are the distance h1 between the corner 112 and the corner 114, and the distance h2 between the corner 116 and the corner 118. It is. In addition, in the present invention, the first and second in the first corner and the second corner are used to distinguish between the corner where the first jig 12 is placed and the corner where the second jig 30 is placed. This is added for convenience. Therefore, the first and second in the present invention have no technical meaning, and as long as the first corner and the second corner are opposite, any of the four corners (102 to 108) in FIG. It may be.

As an example, when measuring the diagonal dimension of the outer shape of the frame 100, that is, the dimension between opposing outer corners, as shown in FIG. A second jig 30 is disposed at a corner opposite to the corner where the first jig 12 is disposed (corresponding to the second corner), and a laser measurement device is attached to the first jig 12. The LM is mounted and the second jig 30 is irradiated with a laser beam from the laser measuring device LM to measure the diagonal dimension between the opposing corners. At this time, as shown in FIG. 3, the direction of the laser measuring device LM is changed as appropriate to measure the longest distance.

FIG. 4 shows a perspective view from above of the first jig 12 included in the jig unit 10 of the present invention, and FIG. 5 shows a perspective view of the first jig 12 from below. Further, FIG. 6 shows a perspective view of the first jig 12 viewed from the opposite side to that in FIG. 5.

As shown in FIGS. 4 to 6, the first jig 12 includes a first wall 14, a second wall 16, a mounting table 18, a projection 20, a first jig-side recess 22, and a first It has a jig side recess 24 and a magnet sheet 26.

The first wall 14 is a substantially rectangular plate-shaped portion, and when the first jig 12 is installed at the first corner, two first extensions intersect with each other at the first corner. It is placed along one side of the wall. That is, the first wall 14 is arranged along one of the two frame side surfaces forming the first corner (see FIG. 10).

The second wall 16 is a substantially rectangular plate-shaped portion, and when the first jig 12 is installed at the first corner, two first extensions intersect with each other at the first corner. It is placed along the other side of the house. That is, the second wall 16 is arranged along the other of the two frame side surfaces forming the first corner (see FIG. 10).

The first wall 14 and the second wall 16 are connected at their ends, and are arranged so that their main surfaces (maximum surfaces) are perpendicular to each other. In other words, the first wall 14 and the second wall 16 are arranged in a direction parallel to the respective main surfaces of the first wall 14 and the second wall 16 (parallel to the ridgeline where the first wall 14 and the second wall 16 intersect). It has an approximately L-shape when viewed from the direction (direction).

The mounting table 18 is a substantially rectangular plate-shaped portion on which the laser measuring device LM is placed.

The mounting table 18 is connected to one end of the first wall 14 and the second wall 16 such that its main surface is perpendicular to each main surface of the first wall 14 and the second wall 16. . In other words, the mounting number 18 is arranged at the end portion where the first wall 14 and the second wall 16 form a substantially L-shape. It can also be said that the mounting table 18 is a portion that extends in a direction intersecting the first wall 14 and the second wall 16.

In the illustrated example, the mounting table 18 supports the first wall 14 and the second wall 16 in a direction perpendicular to both main surfaces of the first wall 14 and in a direction perpendicular to both main surfaces of the second wall 16. It stands out more than that. Since the mounting table 18 protrudes beyond the first wall 14 and the second wall 16, the mounting table 18 functions as a collar, and when the first jig 12 is placed at the first corner, the mounting table 18 functions as a collar. 18 is locked to the first extension of the first corner. That is, the mounting table 18 comes into contact with a surface of the frame 100 that is orthogonal to two frame side surfaces along which the first wall 14 and the second wall 16 lie.

Since the first jig 12 has a first wall 14 and a second wall 16 that are formed in a substantially L-shape, the first wall 14 is connected to one corner of the frame 100, as shown in FIG. The second wall 16 can be placed along the other side forming the corner of the frame 100 . Thereby, the first jig 12 can be easily and precisely placed at the first corner. Moreover, by having the mounting table 18, the laser measuring device LM can be easily and precisely placed at the first corner.

In the illustrated example, as a preferred embodiment, the upper surface of the mounting table 18 is a horizontal surface in a state where the first jig 12 is placed at the first corner of the frame 100 placed horizontally. By making the upper surface of the mounting table 18 a horizontal surface, the laser measuring device LM can be stably installed. Moreover, it becomes possible to reliably irradiate the second jig 30 with the laser light from the laser measurement device LM installed on the mounting table 18.

In the illustrated example, as a preferred embodiment, a convex protrusion 20 is provided on the upper surface of the mounting table 18, that is, on the surface opposite to the first wall 14 and the second wall 16 side. The protrusion 20 has a size and shape that fits into a recess provided in the case of the laser measurement device LM.

When viewed from a direction perpendicular to the top surface of the mounting table 18, the protrusion 20 is formed at the intersection of the first wall 14 and the second wall 16.

Generally, a laser measurement device has a screw hole (corresponding to a recess) in its case for fixing to a tripod or the like, and can measure using the position of the screw hole as a measurement reference point. When placing the laser measurement device on the upper surface of the mounting table 18, the recess provided in the case of the laser measurement device and the protrusion 20 fit together, making it possible to accurately and easily position the laser measurement device. be able to.

In the illustrated example, as a preferred embodiment, a groove-shaped groove extending along the ridgeline where the first wall 14 and the second wall 16 intersect is provided at the inner intersection of the first wall 14 and the second wall 16. It has a recess 22 on the first jig side. That is, the first jig side recess 22 extends in a direction parallel to each of the main surfaces of the first wall 14 and the second wall 16, and perpendicular to each of the main surfaces of the first wall 14 and the second wall 16. The cross-sectional shape is concave.

The corners of the frame 100 may have raised portions due to weld beads. If a raised portion exists at the corner, there is a possibility that the first wall 14 and the second wall 16 of the first jig 12 cannot be arranged along the side surface of the frame. On the other hand, as shown in FIG. 10, by having the first jig side recess 22 at the intersection of the first wall 14 and the second wall 16, the raised part due to the weld bead existing at the corner can be avoided. It becomes possible to arrange the first jig 12 with high precision.

In the illustrated example, as a preferred embodiment, a first jig extending along the ridgeline where the first wall 14 and the second wall 16 intersect is provided at the outer intersection of the first wall 14 and the second wall 16. It has a side recess 24 . In the illustrated example, the outer intersection of the first wall 14 and the second wall 16 is chamfered, and the chamfered portion corresponds to the first jig side recess 24.

As shown in FIG. 11, when measuring the diagonal dimension of the opening 110 of the frame 100, the first jig 12 is placed at a corner (inner corner) of the opening 110. At this time, there may be a raised part due to a weld bead at the corner of the opening 110. If a raised portion exists at the corner, there is a possibility that the first wall 14 and the second wall 16 of the first jig 12 cannot be arranged along the side surface of the frame. On the other hand, by having the first jig side recess 24 at the intersection of the first wall 14 and the second wall 16, the first jig 12 can be precisely This allows for good placement.

In the illustrated example, as a preferred embodiment, magnets are provided on the inner main surfaces of the first wall 14 and the second wall 16, that is, the surfaces that contact the side surfaces of the frame when the first jig 12 is installed at the outer corner of the frame 100. It has a sheet 26. In addition, a magnetic sheet 26 is placed on the outer main surfaces of the first wall 14 and the second wall 16, that is, the surfaces that come into contact with the side surfaces of the frame when the first jig 12 is installed at the inner corner of the opening 110 of the frame 100. have.

Generally, the frame 100 is made of a ferromagnetic material such as steel. Therefore, since the first jig 12 has the magnetic sheet 26, the first jig 12 installed at the corner (outer corner) of the frame 100 or the corner (inner corner) of the opening 110 can be fixed by magnetic force. It is possible to stabilize it. Further, fixing by the magnetic sheet 26 is easy to attach and detach.

There is no limit to the magnetic sheet 26, and various known magnetic sheets can be used as appropriate. Regarding this point, the same applies to the magnet sheet 46 described later.

Next, the second jig 30 will be explained.
FIG. 7 shows a perspective view from above of the second jig 30 included in the jig unit 10 of the present invention, FIG. 8 shows a top view of the second jig 30, and FIG. 30 is shown in a bottom view.

As shown in FIGS. 7 to 9, the second jig 30 includes a third wall 32, a fourth wall 34, a flange 36, a second jig side recess 38, and a second jig side recess 40. and a magnet sheet 46.

The third wall 32 is a substantially rectangular plate-shaped portion, and when the second jig 30 is installed at the second corner, two second extensions intersect with each other at the second corner. It is placed along one side of the wall. That is, the third wall 32 is arranged along one of the two frame side surfaces forming the second corner (see FIG. 10).

The fourth wall 34 is a substantially rectangular plate-shaped portion, and when the second jig 30 is installed at the second corner, two second extensions intersect with each other at the second corner. It is placed along the other side of the house. That is, the fourth wall 34 is arranged along the other of the two frame side surfaces that constitute the second corner (see FIG. 10).

The third wall 32 and the fourth wall 34 are connected at their ends, and are arranged so that their main surfaces (maximum surfaces) are perpendicular to each other. In other words, the third wall 32 and the fourth wall 34 are arranged in a direction parallel to the respective main surfaces of the third wall 32 and the fourth wall 34 (parallel to the ridgeline where the third wall 32 and the fourth wall 34 intersect). It has an approximately L-shape when viewed from the direction (direction).

The flange portion 36 is a generally rectangular plate-shaped portion that extends in a direction intersecting the third wall 32 and the fourth wall 34 . In other words, the flange portion 36 is a plate-shaped portion whose main surface is orthogonal to each main surface of the third wall 32 and the fourth wall 34 . The flange portion 36 extends from the third wall in a direction perpendicular to the respective main surfaces of the third wall 32 and the fourth wall 34 (that is, in a direction parallel to the ridgeline where the third wall 32 and the fourth wall 34 intersect). 32 and the fourth wall 34 are formed at a position that divides the ridge line into two.

In the illustrated example, the flange 36 extends between the third wall 32 and the fourth wall 34 in a direction perpendicular to both main surfaces of the third wall 32 and in a direction perpendicular to both main surfaces of the fourth wall 34. It stands out more than that. Since the flange 36 protrudes beyond the third wall 32 and the fourth wall 34, when the second jig 30 is placed at the second corner, the flange 36 extends from the second extension of the second corner. It is locked on the protrusion. That is, the collar portion 36 contacts a surface of the frame 100 that is orthogonal to two frame side surfaces along which the third wall 32 and the fourth wall 34 extend.

In the example shown in FIG. 7, the region below the collar 36 of the third wall 32 and the fourth wall 34 is a contact portion 42 that contacts the second extension of the frame 100, and the third wall 32 A region above the flange portion 36 of the fourth wall 34 is an irradiated portion 44 that is irradiated with light from the laser measurement device LM. The irradiated portion 44 includes an intersection between the third wall 32 and the fourth wall 34 .

Since the second jig 30 has a third wall 32 and a fourth wall 34 formed in a substantially L-shape, as shown in FIG. The fourth wall 34 may be placed along one side surface forming the corner of the frame 100, and the area corresponding to the contact portion 42 of the fourth wall 34 may be placed along the other side forming the corner of the frame 100. can. Further, the third wall 32 and the fourth wall 34 have an irradiated portion 44 that is irradiated with light from the laser measurement device LM. Therefore, the irradiated portion 44 that is irradiated with light from the laser measurement device LM can be easily and precisely placed at the second corner.

As shown in FIG. 3, when measuring the diagonal dimension of the outer shape of the frame 100, the intersection of the third wall 32 and the fourth wall 34 of the second jig 30 placed at the corner of the frame 100 is , approximately coincides with a corner (outer corner) of the frame 100 in plan view. Therefore, when measuring the diagonal dimension by irradiating the irradiated portion 44 with light from the laser measuring device LM placed on the first jig 12, the intersection of the third wall 32 and the fourth wall 34 is Measurement is performed by irradiating light (see symbol P in FIG. 7). Thereby, the diagonal dimension can be measured with high accuracy. The distance measured by irradiating the intersection with light is longer than when other parts of the third wall 32 or the fourth wall 34 are irradiated with light. Therefore, as shown in FIG. 3, the distance may be measured by appropriately changing the direction of the laser measuring device LM, and the longest distance may be taken as the diagonal dimension.

In the illustrated example, as a preferable aspect, at the inner intersection of the third wall 32 and the fourth wall 34 of the abutting portion 42, a portion extending along the ridge line where the third wall 32 and the fourth wall 34 intersect is provided. It has a groove-shaped second jig side recess 38. That is, the second jig side recess 38 extends in a direction parallel to each of the main surfaces of the third wall 32 and the fourth wall 34, and is perpendicular to each of the main surfaces of the third wall 32 and the fourth wall 34. The cross-sectional shape is concave.

The corners of the frame 100 may have raised portions due to weld beads. If a raised portion exists at the corner, there is a possibility that the third wall 32 and fourth wall 34 of the second jig 30 cannot be arranged along the side surface of the frame. On the other hand, as shown in FIG. 10, by having a second jig side recess 38 at the intersection of the third wall 32 and the fourth wall 34, the raised part due to the weld bead existing at the corner can be avoided. It becomes possible to arrange the second jig 30 with high precision.

In the illustrated example, as a preferable aspect, at the outer intersection of the third wall 32 and the fourth wall 34 of the abutting portion 42, the third wall 32 and the fourth wall 34 extend along the ridgeline where the third wall 32 and the fourth wall 34 intersect. It has a second jig side recess 40. In the illustrated example, the outer intersection of the third wall 32 and the fourth wall 34 is chamfered, and the chamfered portion corresponds to the second jig side recess 40 .

As shown in FIG. 11, when measuring the diagonal dimension of the opening 110 of the frame 100, the second jig 30 is placed at a corner (inner corner) of the opening 110. At this time, there may be a raised part due to a weld bead at the corner of the opening 110. If a raised portion exists at the corner, there is a possibility that the third wall 32 and fourth wall 34 of the second jig 30 cannot be arranged along the side surface of the frame. On the other hand, by having the second jig side recess 40 at the intersection of the third wall 32 and the fourth wall 34, the second jig 30 can be precisely This allows for good placement.

In the illustrated example, as a preferred embodiment, magnets are provided on the inner main surfaces of the third wall 32 and the fourth wall 34, that is, the surfaces that contact the side surfaces of the frame when the second jig 30 is installed at the outer corner of the frame 100. It has a sheet 46. Furthermore, a magnetic sheet 46 is attached to the outer main surfaces of the third wall 32 and the fourth wall 34, that is, the surfaces that will be in contact with the side surfaces of the frame when the second jig 30 is installed at the inner corner of the opening 110 of the frame 100. have.

Generally, the frame 100 is made of a ferromagnetic material such as steel. Therefore, since the second jig 30 has the magnetic sheet 46, it is possible to stabilize the second jig 30 installed at a corner (outer corner) of the frame 100 or a corner (inner corner) of the opening 110. becomes. Further, fixing by the magnetic sheet 46 is easy to attach and detach.

Moreover, as a preferable aspect, at least the inner surfaces of the third wall 32 and the fourth wall 34 of the irradiated portion 44 are white.

By making the inner surfaces of the third wall 32 and the fourth wall 34 of the irradiated portion 44 white, the irradiated light is easily reflected, and measurement can be performed with higher precision.

There are no particular restrictions on the material for forming the first jig 12 and the second jig 30, but resin molded products using PLA (polylactic acid) resin, ABS (acrylonitrile butadiene styrene) resin, etc. are preferable. Thereby, the first jig 12 and the second jig 30 can be manufactured easily and at low cost.

The jig unit 10 of the present invention having the first jig 12 and the second jig 30 described above is suitable for measuring diagonal dimensions between opposing corners (outer corners) of the outer shape of the frame 100. As shown in FIG. 10, a first jig 12 is attached to one of the opposing corners (first corner), and the first wall 14 and the second wall 16 are attached to two corners that intersect with each other at the first corner. The second jig 30 is placed along the outer side surface of each of the first extension parts, and the second jig 30 is placed at the other of the opposing corners (second corner), and the third wall 32 and fourth wall 34 are placed at the second corner. The laser measuring device LM is placed along the outer side surface of each of the two second extending portions that intersect with each other at the first jig 12, and the laser measuring device LM is placed on the mounting table 18 of the first jig 12 to transmit the laser beam to the second jig. 30 and the diagonal dimension can be measured.

In addition, when measuring the diagonal dimension between opposing corners (interior corners) of the opening 110 of the frame 100, as shown in FIG. The first jig 12 is arranged so that the first wall 14 and the second wall 16 are arranged along the inner side surfaces of the two first extensions that intersect with each other at the first corner, and The second jig 30 is placed on the other side (second corner), and the third wall 32 and fourth wall 34 are placed along the inner side surfaces of the two second extensions that intersect with each other at the second corner. The diagonal dimension can be measured by placing the laser measuring device LM on the mounting table 18 of the first jig 12 and irradiating the second jig 30 with laser light.

The jig unit 10 of the present invention allows each of the first jig 12 and the second jig 30 to be installed easily and precisely at the corner of the frame. Therefore, the laser measuring device can be easily and accurately positioned even by one person. Therefore, highly accurate measurement can be performed, and since there is no need to redo the measurement, the measurement can be performed efficiently.

In addition, since the measurement is performed using a laser measuring device LM, there may be cases where the material at the diagonal measurement site is warped, the diagonal dimension is long, or there is a wind effect when measuring outdoors. Even if there is, it is possible to suppress measurement variations. Furthermore, variations in measurement by workers can also be suppressed. Further, even when multiple frames are stacked and placed, or when there is no space for people to pass on all sides of the frames, measurements can be performed more easily than measurements using convex.

One embodiment of the jig unit of the present invention has been described above, but the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. That is, the present invention can be modified and improved without departing from its spirit. Moreover, it goes without saying that the present invention includes equivalents thereof.

In the above embodiment, in the first jig 12, the first wall 14 and the second wall 16 are arranged so that their main surfaces are perpendicular to each other, but the present invention is not limited to this. The angle between the main surfaces of the first wall 14 and the second wall 16 may be set in accordance with the angle of the corner of the frame.

Similarly, in the above embodiment, in the second jig 30, the third wall 32 and the fourth wall 34 are arranged so that their main surfaces are perpendicular to each other, but the present invention is not limited to this. First, the angle formed by the main surfaces of the third wall 32 and the fourth wall 34 may be set in accordance with the angle of the corner of the frame to be measured.

In the above embodiment, each wall (first wall 14 to fourth wall 34) of the first jig 12 and the second jig 30 has a substantially rectangular main surface, but each wall has a substantially rectangular shape. The arrangement is not limited to this as long as it can be arranged along the protrusion. For example, the shape of the main surface of each wall may be another shape such as a polygonal shape such as a triangle.

Furthermore, in the above embodiment, the first jig 12 has a projection 20 on the top surface of the mounting table that fits into a recess provided in the case of the laser measurement device LM. It is also possible to have a configuration that does not have this. However, as described above, the configuration having the protrusion 20 is preferable in that the laser measurement device LM can be positioned with higher precision.

Further, in the above embodiment, in the first jig 12, the upper surface of the mounting table 18 is a horizontal surface, but the upper surface is not limited to this. However, as described above, the configuration in which the upper surface of the mounting table 18 is a horizontal surface allows the laser measurement device LM to be stably installed, and the laser beam from the laser measurement device LM installed on the mounting table 18 can be This is preferable in that it is possible to reliably irradiate the second jig 30.

Further, in the above embodiment, the mounting table 18 is arranged in a direction perpendicular to both main surfaces of the first wall 14 and in a direction perpendicular to both main surfaces of the second wall 16. Although the configuration is such that it protrudes beyond the two walls 16 and functions as a flange, the present invention is not limited to this, and the mounting table 18 may have a configuration in which it does not function as a flange. However, as described above, a configuration in which the mounting table 18 functions as a flange is preferable in that the first jig 12 can be easily and reliably installed at a corner.

Further, in the above embodiment, the main surface of the mounting table 18 has a substantially rectangular shape, but is not limited to this as long as the laser measuring device LM can be mounted thereon, and may have other shapes such as a polygonal shape such as a triangle. It may be.

Further, in the above embodiment, the intersection between the first wall 14 and the second wall 16 of the first jig 12 and the third wall 32 and the fourth wall 34 of the contact portion 42 of the second jig 30 are Although the first jig-side recesses (22, 24) or the second jig-side recesses (38, 40) are provided at the intersection with the first jig side recesses (22, 24), the present invention is not limited thereto. The inner and outer intersections between the first wall 14 and the second wall 16 of the first jig 12, and the inner and outer intersections between the third wall 32 and the fourth wall 34 of the abutting portion 42 of the second jig 30. The structure may include a first jig-side recess or a second jig-side recess at at least one location of the outer intersection. Alternatively, the first jig 12 and the second jig 30 may be configured without the first jig-side recess or the second jig-side recess. However, as described above, in the configuration having the first jig side recess or the second jig side recess, the first jig side recess or the second jig side recess creates a bulge due to a weld bead existing at the corner of the frame. This is preferable in that it is possible to arrange the first jig 12 and the second jig 30 while avoiding the parts.

Further, in the above embodiment, the first jig 12 and the second jig 30 have the magnet sheets (26, 46) on both main surfaces of the walls (first wall to fourth wall). It is not limited to this. The structure may include a magnet sheet on at least one of both main surfaces of the walls (first wall to fourth wall). For example, in the first jig 12, only the first wall 14 may have a magnetic sheet, or only the second wall 16 may have a magnetic sheet. Alternatively, a configuration may be adopted in which a magnet sheet is provided on one main surface of the first wall 14 and one main surface of the second wall 16. Similarly, in the second jig 30, only the third wall 32 may have a magnetic sheet, and only the fourth wall 34 may have a magnetic sheet. Alternatively, a configuration may be adopted in which a magnet sheet is provided on one main surface of the third wall 32 and one main surface of the fourth wall 34. Alternatively, the first jig 12 may have a magnetic sheet on the wall (the first wall 14 and/or the second wall 16), and the second jig 30 may have no magnetic sheet. Alternatively, both the first jig 12 and the second jig 30 may be configured without a magnetic sheet. However, as described above, the configuration including the magnetic sheet is preferable in that it is possible to stabilize the first jig 12 and/or the second jig 30 installed at the corner of the frame.

Further, in the above embodiment, the second jig 30 has a flange portion 36 extending in a direction intersecting the third wall 32 and the fourth wall 34 between the contact portion 42 and the irradiated portion 44. Although the second jig 30 is disposed at the second corner with the flange 36 being engaged with the two second extensions, the present invention is not limited thereto.
