Description

The present invention relates to a panel zone assembly jig and a panel zone assembly method, and is directed to a panel zone assembly jig and a panel zone assembly method for assembling a panel zone core that constitutes the building structure and a bracket that is arranged opposite the outer surface of the core.

Conventionally, in order to assemble a panel zone core and a bracket arranged opposite the outer surface of the core, an assembly jig has been proposed that includes a mounting table for placing the core and a mounting table for placing the bracket, and adjusts the position of the bracket relative to the core (see, for example, Patent Document 1).

The assembly jig described in Patent Document 1 includes a lifting means for setting the vertical position of the bracket relative to the core on the core mounting base (receiving base), and holding members (contact body and pressing body) for setting the left and right position of the bracket. When assembling, the core is first placed on the core mounting base and positioned. Then, the bracket is placed on the bracket mounting base and the vertical and left and right positions are set. With the bracket held in place, the bracket is moved by rotating rollers until it is brought into contact with the core.

Japanese Patent Publication No. 4-062839

However, because an assembly jig like that in Patent Document 1 fixes the bracket with a contact body and a pressing body, it is difficult to adjust the left-right position of the bracket relative to the core, which can reduce work efficiency.

Furthermore, in an assembly jig such as that disclosed in Patent Document 1, the vertical position of the bracket is adjusted by raising and lowering the rotating rollers using a jack, which serves as a lifting means, so there is a risk that the jig will become large.
Furthermore, since the bracket is placed on a rod-shaped rotating roller, there is a risk that the bracket may fall off the rotating roller when the bracket is brought into contact with the core.

The present invention was made in consideration of the above problems, and the object of the present invention is to provide a panel zone assembly jig and a panel zone assembly method that improves the workability of adjusting the position of the bracket relative to the core while forming a compact assembly jig.

The above problem is solved by the panel zone assembly jig of the present invention, which is a panel zone assembly jig for assembling a core of a panel zone that constitutes the framework of a building and a bracket that is arranged opposite the outer surface of the core, and which includes a core mounting base on which the core is placed, and a bracket mounting base that is arranged alongside the core mounting base and on which the bracket is placed so as to face the core, the core mounting base having a base member on which the core is placed and a positioning member that determines the position of the core placed on the base member, the bracket mounting base extending long along the direction in which the mounting bases are arranged, and having a table member on which the bracket is placed, holding members that hold the bracket from both sides in the width direction of the table member, and a movable member that moves the table member in the width direction, and the table member moves in the width direction by the movable member while the bracket is held by the holding member.

With the above configuration, the table member can be moved in the width direction, making it easy to adjust the widthwise position (left-right position) of the bracket relative to the core, thereby improving positioning accuracy and reducing work time.
In addition, since the table member extends long from the core mounting base, the bracket can be stably mounted on the table member. This makes it easier to move the bracket toward the core, improving workability. In addition, since a large device such as an abutment device is not required, a compact assembly jig can be used.
Furthermore, because the bracket can be stably placed on the table member, fine adjustment of the bracket's vertical position can be made by inserting a shim plate between the table member and the bracket. This eliminates the need for a large device such as a lifting device, allowing for a compact assembly jig.

In this case, the holding member has a support portion that supports one end of the bracket from the width direction, and a pressing portion that presses the other end of the bracket toward the support portion from the width direction, and the pressing portion has a clamp that abuts the bracket from the width direction, and a clamp operating portion that operates the clamp to be movable in the width direction, and the holding member holds the bracket from both sides in the width direction by the clamp and the support portion when the clamp operating portion is operated.
With the above-described configuration, the bracket can be easily held by the clamp operating portion, and the left and right positions of the bracket can be adjusted in a stable state when the table member is moved.

In this case, it is preferable that the table member has a plurality of mounting portions spaced a predetermined distance apart in the width direction, and the pressing portion is detachably attached to a predetermined one of the mounting portions.
With the above-mentioned configuration, since the pressing portion is detachable from the table member, the separation distance of the holding members can be easily changed, and therefore brackets of different sizes in the width direction can be held in appropriate positions.

In this case, the movable member has a rail portion extending in the width direction, a guide portion provided below the table member and moving in the width direction guided by the rail portion, and a table operating portion provided on the table member, and the table member is arranged to abut against the base member, and the table operating portion is operated to move in the width direction along the base member.
With the above-mentioned configuration, the left-right position of the bracket with respect to the core can be adjusted while the table member and the base member are in contact with each other. This prevents a gap from being formed between the table member and the base member, and allows the bracket to be easily pressed against the core.

In this case, the bracket mounting base has a protective member that protects the upper part of the movable member, and the protective member is attached to the rail end of the rail portion in the width direction and to the table end on the rail end side in the width direction of the table member, and the table member moves in the width direction with the protective member spanning the rail end and the table end.
With the above-described configuration, by providing a protective member on the movable member, the movable member can be protected from spatter when welding the panel zone on the table.

Furthermore, the above problem is solved by a panel zone assembly method of the present invention, which is a panel zone assembly method using a panel zone assembly jig, and includes a placing step of placing the core on the core mounting base and the bracket on the bracket mounting base, a positioning step of positioning the core at a predetermined position using the positioning member, a holding step of holding the bracket from both sides in the width direction using the holding member, an abutting step of abutting the bracket against the core, a position adjustment step of moving the table member in the width direction with the bracket held by the holding member to adjust the position of the bracket in the width direction relative to the core, and a welding step of welding the abutted core and bracket.
With the above-mentioned configuration, the panel zone can be assembled without using a crane, thereby improving work efficiency and safety. In addition, since the bracket can be stably placed on the table member, the panel zone can be welded in a stable state.

In this case, in the placement process, the worker adjusts the height position of the bracket by placing a shim plate between the bracket and the table member, and in the abutment process, the worker presses the bracket toward the core to abut the bracket against the core.
With the above-mentioned configuration, the worker can manually adjust the vertical position of the bracket and manually abut the bracket against the core. Therefore, large devices such as a lifting device and an abutment device are not required, and a compact assembly jig can be used.

The panel zone assembly jig and panel zone assembly method of the present invention can improve the workability of adjusting the position of the bracket relative to the core while forming a compact assembly jig.

FIG. 2 is a top view of the panel zone assembly jig. 13 is a diagram showing a core and a bracket placed on a panel zone assembly jig. FIG. FIG. 13 is a top view of the panel zone, showing the state assembled using the panel zone assembly jig. 1A to 1C are diagrams illustrating a manufacturing process of the panel zone.

A panel zone assembly jig 1 according to one embodiment of the present invention (hereinafter, this embodiment) will be described below with reference to Figures 1 to 6. In the following description, the "vertical direction" refers to the vertical direction of the core C in an upright position. The "horizontal direction" refers to the width direction of the core C in an upright position.
The direction in which the core C and bracket B face each other when they are upright is referred to as the "facing direction." In the "facing direction," the outside and inside are defined based on the outer surface of the core C. In other words, the direction in which bracket B approaches the outer surface of the core C is referred to as the "inner direction," and the direction in which bracket B moves away from the outer surface of the core C is referred to as the "outer direction."
In addition, the width direction of the outer surface of the core C when viewed from the front in an upright state is defined as the "left-right direction." The "left-right direction" is a direction perpendicular to the "up-down direction" and the "facing direction."

<Panel zone assembly jig>
As shown in Figures 1 to 3, the panel zone assembly jig 1 is used to assemble a core C of a panel zone P that constitutes the structure of a building and a bracket B that is arranged opposite the outer surface of the core C.
More specifically, the panel zone P is assembled by a panel zone assembly jig 1, in which a bracket B is brought into contact with a core C and the core C and the bracket B are welded together.

As shown in Figure 1, the panel zone P is a joint member for joining the column member and the beam. The column member and the beam can be joined by connecting the core C to the column member and joining the beam to the outer end of the bracket B.

The core C is a square steel pipe with a rectangular cross section, and serves as a joint member on the column member side for joining the column member and the beam. A diaphragm D is welded to the upper and lower ends of the core C. The diaphragm D is a rectangular steel plate, and serves as a joint portion that joins with the column member.
The bracket B is an H-shaped steel member extending long in the opposing direction, and is a beam-side joint member for joining the column member and the beam. Flanges F are formed on the upper and lower ends of the bracket B.

As shown in FIG. 1, the panel zone P is assembled by placing a core C in the center of a panel zone assembly jig 1, placing brackets B on each of the four sides of the core C, and welding the core C and brackets B together.
Specifically, the panel zone P is composed of a core C, a first bracket B1 that is lower in height than the core C, and a second bracket B2 that is the same height as the core C. The panel zone P is formed by fixing the first bracket B1 and the second bracket B2 to the core C by welding.
In this embodiment, the panel zone P is formed by brackets B of different heights, but this is not limited to the above, and all brackets B may be of the same height. Also, the number of connected brackets B is not limited to four, but may be one to three, or five or more.

As shown in Figures 1 and 2, the panel zone assembly jig 1 is mainly composed of a base 2, a core mounting table 3 for mounting a core C, and a bracket mounting table 4 for mounting a bracket B.
The base 2 is formed in a generally cross shape when viewed from above, and supports from below the core mounting base 3 and the bracket mounting base 4. The bracket mounting base 4 is disposed alongside the core mounting base 3, and mounts the bracket B thereon so as to face the core C.

<Core placement table>
The core mounting table 3 is attached to the upper side in the central portion of the base body 2, and is a table for mounting the core C. The core mounting table 3 has a base member 10 for mounting the core C, and a positioning member 20 for determining the position of the core C mounted on the base member 10.

As shown in FIGS. 2 and 3, the base member 10 has a core mounting portion 11 on which the core C is mounted, and a slit portion 12 through which the positioning member 20 can be moved.
The core mounting portion 11 is a metal plate formed in a rectangular shape when viewed from above, and has slits 12 formed on its diagonal lines.

The positioning member 20 determines the position of the core C placed on the core placement portion 11. As shown in Figures 2 and 3, the positioning member 20 has a main body portion 21 attached to the upper surface of the base 2, a guide portion 22 provided on the main body portion 21, a moving portion 23 that moves while being guided by the guide portion 22, a clamping portion 24 attached to the moving portion 23, a shaft portion 25 for moving the moving portion 23, and a first handle 26 for rotating the shaft portion 25.

2 and 3, the main body 21 is a long plate-like member extending along the diagonal direction of the core mounting portion 11, and is attached to the upper surface of the base 2. Shaft holders 21a are attached to both ends of the main body 21 in the longitudinal direction.
The guide portion 22 is provided at both ends in the width direction of the main body portion 21, and the moving portion 23 is attached so as to be movable in the diagonal direction. A leading end stopper 22a and a trailing end stopper 22b are provided at both ends in the length direction of the guide portion 22.

2 and 3 , the moving part 23 is guided by the guide part 22 and moves in a diagonal direction below the core mounting part 11. The moving part 23 has a first moving plate 23a arranged on the first handle 26 side and a second moving plate 23b arranged on the opposite side to the first handle 26.
The first moving plate 23a is attached to the guide portion 22 and moves between the core mounting portion 11 and the front end stopper 22a. The second moving plate 23b is attached to the guide portion 22 and moves between the core mounting portion 11 and the rear end stopper 22b.

A guided portion (not shown) that is slidable along the guide portion 22 is provided on the lower surface of the first moving plate 23a and the second moving plate 23b, and the moving portion 23 moves in a diagonal direction along the guide portion 22.
In addition, a mounting screw portion (not shown) that screws into the shaft portion 25 is provided on the underside of the first moving plate 23a and the second moving plate 23b, and the moving portion 23 moves in the diagonal direction as the shaft portion 25 rotates.

2 and 3, the clamping part 24 is fixed to the moving part 23, passes through the slit part 12 as the moving part 23 moves, and moves in a diagonal direction above the core placement part 11. The clamping part 24 has a first block 24a fixed to the first moving plate 23a and a second block 24b fixed to the second moving plate 23b.
The opposing surfaces of the first block 24a and the second block 24b are formed in a V-shape so as to abut against the corners of the core C. The corners of the core C are clamped from the sides by the pair of clamping portions 24, so that the core C can be positioned.

2 and 3, the shaft portion 25 is a long ball screw member that is attached to the shaft holding portion 21a along the diagonal direction of the core mounting portion 11. When the shaft portion 25 is rotated by the first handle 26, the moving portion 23 attached to the shaft portion 25 moves in the diagonal direction.
The first handle 26 is an operating part that is operated by an operator, and is detachably attached to one shaft end 25a in the longitudinal direction of the shaft part 25.

4, the first block 24a and the second block 24b are disposed diagonally across the core placement portion 11. When the first handle 26 is operated, the shaft portion 25 rotates, and the first block 24a and the second block 24b move relatively closer to or farther away from each other. Therefore, the core C can be centered and fixed at the central position by the pair of clamping portions 24.
In this manner, by manually operating the first handle 26, the operator can easily position the core C and fix it at the center position.

<Bracket mounting stand>
1, the bracket mounting table 4 is attached to the upper side of the base 2 around the core mounting table 3, and is a table for mounting the bracket B. The bracket mounting table 4 is composed of four mounting tables (a first mounting table 4A, a second mounting table 4B, a third mounting table 4C, and a fourth mounting table 4D), and is arranged side by side with the core mounting table 3 on all four sides of the core mounting table 3.
The end of the positioning member 20 on the first handle 26 side is positioned between the first mounting table 4A and the fourth mounting table 4D, and the end on the opposite side of the first handle 26 is positioned between the second mounting table 4B and the third mounting table 4C.

2 and 3, the bracket mounting base 4 has a table member 30 on which the bracket B is mounted, a holding member 40 provided on the upper surface of the table member 30, a movable member 50 that mounts the table member 30 so as to be movable in the left-right direction relative to the base 2, and a protective member 60 that protects the upper part of the movable member 50. Each component of the bracket mounting base 4 will be described using the first mounting base 4A as an example. The components of the second mounting base 4B, the third mounting base 4C, and the fourth mounting base 4D are omitted because they are similar to the first mounting base 4A.

2 and 3, the table member 30 has a bracket mounting portion 31 on which the bracket B is mounted. The bracket mounting portion 31 is a metal plate that extends in a longitudinal direction along the arrangement direction of the core mounting base 3 and the bracket mounting base 4 (the opposing direction of the core C and the bracket B), and is attached to the base 2 so as to be movable in the left-right direction.
The bracket mounting portion 31 is formed in a generally trapezoidal shape when viewed from above in order to avoid interference with the positioning member 20 when moved in the left-right direction. Specifically, the left end portion 31a in the width direction of the bracket mounting portion 31 is formed shorter than the right end portion 31b, so that the bracket mounting portion 31 can be moved in the left direction without interfering with the positioning member 20 arranged on the left side.

The bracket mounting portion 31 is formed with a plurality of mounting portions 31c. The mounting portions 31c are holes that penetrate in the vertical direction, and are formed at positions spaced a predetermined distance apart in the width and length directions of the bracket mounting portion 31.

As shown in Figures 2 and 3, the bracket mounting portion 31 is positioned so as to abut against the core mounting portion 11 of the base member 10, and the upper surface of the core mounting portion 11 and the upper surface of the bracket mounting portion 31 are positioned side by side in a substantially flush state.
5, the worker can slide the upper surfaces of the core mounting portion 11 and the bracket mounting portion 31 to bring the bracket B into contact with the core C. Note that "to come into contact" means that the bracket mounting portion 31 can move in the left-right direction along the core mounting portion 11 and is in a position where the bracket B can be smoothly slid, and it is not necessary for the core mounting portion 11 and the bracket mounting portion 31 to be in contact with each other.

In this manner, the core mounting portion 11 and the bracket mounting portion 31 are arranged side by side so as to abut against each other. Since the table member 30 is arranged so as to be continuous with the base member 10, the worker can move the bracket B smoothly when manually pushing the bracket B.
In addition, since the bracket mounting portion 31 is formed in a substantially trapezoidal shape when viewed from above, the area of the mounting surface can be increased while avoiding interference with the positioning member 20. Therefore, even a bracket B that is long in the width direction can be stably mounted on the bracket mounting portion 31.

Furthermore, the bracket mounting portion 31 extends long along the arrangement direction of the core mounting base 3 and the bracket mounting base 4. The width and length of the bracket mounting portion 31 are longer than those of the bracket B, allowing the bracket B to be stably mounted thereon.
Therefore, by inserting a shim plate between the lower flange F of the bracket B and the bracket mounting portion 31, fine adjustment of the height position is possible.

The holding member 40 holds the position of the bracket B placed on the bracket mounting portion 31 from both the left and right sides. As shown in Figures 2 and 3, the holding member 40 has a support portion 41 that supports the right end portion of the bracket B, and a pressing portion 42 that presses the left end portion of the bracket B.

As shown in Figures 2 and 3, the support part 41 is a long member that extends along the length of the bracket mounting part 31 and is provided so as to protrude upward from the upper surface of the bracket mounting part 31. The support part 41 is provided on the right end part 31b side of the bracket mounting part 31 and supports one end of the bracket B from the right side.

2 and 3, a plurality of pressing parts 42 are provided and are detachably attached to the plurality of attachment parts 31c of the bracket mounting part 31. The pressing part 42 is provided on the left end part 31a side of the bracket mounting part 31 and presses the bracket B from the left side. The pressing part 42 has a clamp 42a that abuts against the bracket B and a clamp operating part 42b that movably operates the clamp 42a.
The clamp 42a is a rectangular metal plate that presses to the right the other end of the bracket B. The clamp operation portion 42b is, for example, a clamp screw that is rotated by an operator to move the clamp 42a in the left-right direction.

As shown in FIG. 4, when the clamp operating portion 42b of the holding member 40 is operated by an operator, the clamp 42a is brought into contact with the bracket B, and the bracket B is held from both sides in the width direction by the support portion 41 and the clamp 42a.
In this manner, the bracket B can be easily held by pressing the clamp 42a toward the support portion 41 with the clamp operating portion 42b. Therefore, when the table member 30 is moved in the left-right direction by the movable member 50, the left-right position of the bracket B is held by the holding member 40, so that the left-right position of the bracket B can be stabilized.

The movable member 50 moves the table member 30 in the left-right direction to adjust the left-right position of the bracket B relative to the core C. As shown in Figures 2 and 3, the movable member 50 has a movable main body part 51 attached to the upper surface of the base 2, a rail part 52 provided on the movable main body part 51, a guide part 53 that moves in the left-right direction guided by the rail part 52, a rotating shaft part 54 for moving the table member 30, and a second handle 55 for rotating the rotating shaft part 54.

2 and 3, the movable main body part 51 is a plate-like member that is long along the left-right direction, and is attached to the upper surface of the base body 2. Shaft support parts 51a are attached to both ends of the movable main body part 51 in the longitudinal direction.
The rail portion 52 extends in the left-right direction, and is provided at both ends in the width direction of the movable main body portion 51. A right stopper 52a and a left stopper 52b are provided at both ends in the length direction of the rail portion 52.

As shown in Figures 2 and 3, the guide portion 53 is provided below the table member 30 and moves left and right while being guided by the rail portion 52. The guide portion 53 is provided on the lower surface of the bracket mounting portion 31 and is slidably attached to the rail portion 52.

As shown in Figures 2 and 3, the bracket mounting portion 31 of the table member 30 moves in the left-right direction along the core mounting portion 11 as the guide portion 53 is guided by the rail portion 52. The bracket mounting portion 31 is attached to the rail portion 52 so as to be movable between the right stopper 52a and the left stopper 52b.

As shown in Figures 2 and 3, the rotating shaft portion 54 is a long ball screw member that runs along the left-right direction of the bracket mounting portion 31 and is attached to the shaft support portion 51a. A mounting screw portion (not shown) that screws into the rotating shaft portion 54 is provided on the underside of the bracket mounting portion 31. The bracket mounting portion 31 of the table member 30 moves in the left-right direction as the rotating shaft portion 54 is rotated by the second handle 55.

The second handle 55 is a table operating section that is operated by an operator, and is detachably attached to one of the rotation shaft ends 54 a in the longitudinal direction of the rotation shaft section 54 .
The second handle 55 may be a handle shared with the first handle 26. By sharing a handle, the assembly jig can be configured more compactly.

As shown in FIG. 4 , when the second handle 55 is operated, the rotation shaft portion 54 of the table member 30 rotates, and the bracket mounting portion 31 moves in the left-right direction along the core mounting portion 11 .
In this manner, the table member 30 moves in the left-right direction by the movable member 50 while holding the bracket B by the holding member 40. Therefore, the operator can easily adjust the left-right position of the bracket B with respect to the core C by manually operating the second handle 55.

The protective member 60 protects the upper part of the movable member 50. As shown in FIG. 1, the protective member 60 has a stopper attachment part 61 that is attached to the right stopper 52a in the width direction of the rail part 52, and a table attachment part 62 that is attached to the right end part 31b of the table member 30 on the right stopper 52a side in the width direction.

The protective member 60 is a flexible cover that is spanned across the right stopper 52 a of the movable member 50 and the right end portion 31 b of the table member 30 .
Therefore, the table member 30 moves in the width direction with the protective member 60 suspended between the right stopper 52 a and the right end portion 31 b. Therefore, even when the table member 30 moves, the protective member 60 flexes, thereby protecting the upper part of the movable member 50.

In this way, even when welding is performed on the panel zone assembly jig 1, the protective member 60 covers the upper part of the movable member 50, so that the movable member 50 can be protected from spatter generated during welding.
In the present embodiment, the protective member 60 is a flexible cover, but is not limited thereto. For example, the protective member 60 may be a bellows-like cover that expands and contracts.

<How to assemble the panel zone>
Next, a method for assembling the panel zone P using the panel zone assembly jig 1 will be described with reference to FIGS.
6, this method includes at least a "mounting step" of mounting a core C and a bracket B, a "positioning step" of positioning the core C at a predetermined position, a "holding step" of holding the bracket B, an "abutment step" of abutting the bracket B against the core C, a "position adjustment step" of adjusting the position of the bracket B, and a "welding step" of welding the abutted core C and bracket B. These steps will be described in detail below.
It should be noted that the explanation of other steps in assembling the panel zone P will be omitted.

In the "mounting step", as shown in Fig. 4, a worker places a core C on the core mounting portion 11 of the base member 10. At this time, the core C is disposed between the pair of clamping portions 24. In addition, the worker places a bracket B on the bracket mounting portion 31 of the table member 30.
In addition, when adjusting the vertical position of bracket B in the "mounting process", the worker adjusts the height position of bracket B by placing any number of shim plates between bracket B and bracket mounting portion 31.

In this way, when adjusting the vertical position of bracket B, the worker can easily adjust the height position of bracket B manually, which allows the assembly jig to have a simple configuration. Note that the timing for adjusting the height position of bracket B by sandwiching the shim plate is not limited to the "placing process," but may also be the "holding process" or "position adjustment process."

In the "positioning step", as shown in FIG. 4, an operator positions the core C at a predetermined position (for example, the center position of the core placement portion 11) using the positioning member 20.
Specifically, the operator rotates the shaft portion 25 by operating the first handle 26, and brings the pair of clamping portions 24 closer to each other. Then, the pair of clamping portions 24 are moved to positions where they abut against corner portions of the core C.
In this way, the operator can easily position the core C and fix the core C on the core mounting portion 11 by manually operating the first handle 26 .

In the "holding step", as shown in FIG. 4, a worker holds the bracket B from both sides in the width direction with the holding members 40.
First, the worker positions one side of the bracket B so that it abuts against the support portion 41. Then, by operating the clamp operating portion 42b, the clamp 42a abuts against the other side of the bracket B, and the bracket B is held from both sides in the width direction by the support portion 41 and the clamp 42a.
In this manner, the worker can easily hold the bracket B by manually operating the clamp operating portion 42b.

4 and 5, in the "abutment step", the worker pushes the bracket B to abut the bracket B against the core C. Specifically, with the bracket B held in position in the width direction by the holding member 40, the worker pushes the bracket B toward the core C along the support portion 41 to abut the bracket B against the core C. When abutting the bracket B against the core C, the clamp 42a is loosened and the bracket B is pressed against the core C in a state that makes it easy to abut the bracket B.
In this way, the worker can easily manually abut the bracket B against the core C by sliding the upper surfaces of the core mounting portion 11 and the bracket mounting portion 31, thereby allowing the jig body to have a simple configuration.

In the "position adjustment process", as shown in Figure 5, while the bracket B is held by the holding member 40, the worker moves the table member 30 in the width direction using the movable member 50 to adjust the width direction position of the bracket B relative to the core C.
Specifically, the worker rotates the rotating shaft portion 54 by operating the second handle 55, and moves the table member 30 in the width direction. Then, the bracket B is moved to a position facing the outer surface of the core C.
When adjusting the widthwise position of the bracket B relative to the core C, the clamps 42a, which have been loosened when they come into contact, are pressed against the support parts 41 to hold the bracket B from both sides in the widthwise direction. Note that after the bracket B is held, the widthwise position of the bracket B relative to the core C may be finely adjusted.
In this manner, by manually operating the second handle 55 , the worker can easily adjust the position of the bracket B while the bracket B is held by the holding member 40 .

In the "welding process", the worker welds the abutted core C and bracket B on the panel zone assembly jig 1. At this time, the protective member 60 covers the upper part of the movable member 50, so spatter generated during welding can be prevented from entering the movable member 50.

The above-described method for assembling the panel zone allows the panel zone P to be assembled without using large equipment such as lifting devices or cranes, improving work efficiency and safety. In addition, the bracket B can be stably placed on the table member 30, allowing the panel zone P to be welded in a stable state.
