In the panel position adjustment method of this embodiment with the above configuration, the pressing portion 7 of the panel position adjustment jig 1 can be brought into contact with the accessory part 30 of the panel 3 to slide the panel 3, thereby preventing scratches on the panel 3.

2. Details Next, the panel position adjustment jig 1 of the present embodiment shown in Figs. 1 to 4 and the panel position adjustment method using the same will be described in more detail.

In the following, each component will be described in detail, with the longitudinal direction of the cross member 2 shown in FIG. 1 defined as the left-right direction, the side where the panel 3 is located relative to the cross member 2 defined as the front, the opposite side defined as the rear, and the direction perpendicular to the left-right and front-to-rear directions defined as the up-down direction.

2-1 Panel Position Adjusting Jig The panel position adjusting jig 1 includes a jig body 4, a hook portion 5, a fixing operation portion 6, a pressing portion 7, and a sliding operation portion 8, as shown in FIGS.

2-1-1. Jig body As shown in Fig. 1 and Fig. 2, the jig body 4 is a member extending in one direction. In this embodiment, the jig body 4 is a rod-shaped member 40 having a screw groove 400 on its outer circumferential surface. The screw groove 400 is provided in a spiral shape. A pressing part 7 is attached to one end (the left end in this embodiment) in the longitudinal direction of the rod-shaped member 40, and a hook part 5 and a slide operation part 8 are attached to the other part (the right part in this embodiment) in the longitudinal direction of the rod-shaped member 40. In this embodiment, the jig body 4 is made of metal.

2-1-2. Hooking Part The hooking part 5 is configured so as to be hooked onto the cross member 2. In this embodiment, the hooking part 5 is in the shape of a substantially rectangular parallelepiped block, as shown in Fig. 1 and Fig. 3. The hooking part 5 has an insertion groove 50 into which a vertical plate part 20 of the cross member 2, which will be described later, is inserted, and an insertion hole 51 into which the rod-shaped member 40 is inserted. In this embodiment, the hooking part 5 is made of metal.

More specifically, the hook portion 5 has a first vertical piece 52 that is rectangular and has a longitudinal direction in the up-down direction, a horizontal piece 53 that extends forward from the upper end of the first vertical piece 52, and a second vertical piece 54 that is rectangular and extends downward from the front end of the horizontal piece 53.

The second vertical piece 54 is parallel to the first vertical piece 52 and is located a distance away from the first vertical piece 52 that is approximately the same as the thickness of the vertical plate portion 20 of the cross member 2. The space surrounded by the first vertical piece 52, the horizontal piece 53, and the second vertical piece 54 is the insertion groove 50 into which the vertical plate portion 20 is inserted.

The first vertical piece 52 has a screw hole 520 that penetrates a portion of the first vertical piece 52 in the front-rear direction. The screw hole 520 is connected to the insertion groove 50. The first vertical piece 52 has an insertion hole 51 in a portion above the screw hole 520. The insertion hole 51 is located above the screw hole 520.

The diameter of the insertion hole 51 is larger than the diameter of the rod-shaped member 40. This allows the hook portion 5 to be moved to any position along the length of the rod-shaped member 40.

The fixing operation unit 6 is configured to be able to fix and release the hooking portion 5 to and from the cross member 2. In this embodiment, as shown in Fig. 2 and Fig. 3, the fixing operation unit 6 has a fixing bolt 60 attached to the hooking portion 5 and an operation lever 61 connected to the fixing bolt 60 so as to move toward and away from the cross member 2.

In detail, the fixing bolt 60 has a shaft portion 62 inserted into the screw hole 520 of the first vertical piece 52 of the hook portion 5, and a head portion 63 provided at the rear end of the shaft portion 62. The operation lever 61 is connected to the head portion 63. The head portion 63 is hexagonal columnar. As shown in FIG. 2, the operation lever 61 has a strip-shaped handle portion 610 that can be held by the installer, a connecting hole 611, and a rotation restricting portion 612. The connecting hole 611 is a hexagonal hole. The operation lever 61 is connected to the fixing bolt 60 by fitting the head portion 63 of the fixing bolt 60 into the connecting hole 611, and operates integrally with the fixing bolt 60. At this time, the mounting angle of the operation lever 61 relative to the head portion 63 can be appropriately selected, and the protruding length of the shaft portion 62 of the fixing bolt 60 into the insertion groove 50 of the hook portion 5 can be changed as desired.

The rotation restriction portion 612 is composed of a rod-shaped member attached to one end of the operating lever 61 in the longitudinal direction. In this embodiment, this rod-shaped member is a bolt 64. When the operating lever 61 is connected to the fixing bolt 60, the rotation restriction portion 612 protrudes forward from the operating lever 61 and extends parallel to the fixing bolt 60.

The fixing operation unit 6 can adjust the amount of protrusion of the shaft portion 62 of the fixing bolt 60 from the first vertical piece 52 to the front side by gripping the operation lever 61 and rotating the fixing bolt 60 around its axis. In this embodiment, the operation lever 61 can be rotated within a range from a position where the rotation restriction portion 612 hits a portion of the rod-shaped member 40 on the opposite side (right side) of the pressing portion 7 from the hook portion 5 or a second operation portion 81 (described later) of the slide operation unit 8 located in this portion, and the operation lever 61 is approximately parallel to the rod-shaped member 40, to a position where the rotation restriction portion 612 hits a portion of the rod-shaped member 40 on the pressing portion 7 side (left side) from the hook portion 5 or a first operation portion 80 (described later) of the slide operation unit 8 located in this portion, and the operation lever 61 is approximately parallel to the rod-shaped member 40. In other words, the operation lever 61 can be rotated within a range of approximately 0 to 180 degrees with respect to a reference line that is parallel to the rod-shaped member 40 and passes through the center of the head 63 of the fixing bolt 60. The rotation restriction portion 612 prevents the operating lever 61 from rotating more than a predetermined amount, which prevents the fixing bolt 60 from falling out of the threaded hole 520 of the hook portion 5 and from protruding unnecessarily into the insertion groove 50.

The hook portion 5 is fixed to the cross member 2 by rotating the operating lever 61 clockwise as viewed from the rear and pressing the tip (front end) of the shaft portion 62 of the fixing bolt 60 against the vertical plate portion 20. The hook portion 5 is released from the cross member 2 by rotating the operating lever 61 counterclockwise to move the tip (front end) of the shaft portion 62 of the fixing bolt 60 away from the vertical plate portion 20. In this embodiment, the hook portion 5 can be fixed to the cross member 2 by grasping the operating lever 61 and tilting it to the right (rotating it clockwise) as viewed from the rear, and the hook portion 5 can be released from its fixed state to the cross member 2 by grasping the operating lever 61 and tilting it to the left (rotating it counterclockwise) as viewed from the rear.

The operating lever 61 may also be configured to switch from the unlocked state to the locked state by rotating it counterclockwise as viewed from the rear. In other words, the shaft 62 of the fixing bolt 60 may be a reverse thread that closes when turned counterclockwise as viewed from the rear.

2-1-4. Slide operation unit The slide operation unit 8 is configured to be able to slide the pressing unit 7 in the longitudinal direction of the jig body 4. In this embodiment, the slide operation unit 8 includes a first operation unit 80 and a second operation unit 81 rotatably attached to the jig body 4, as shown in Figs.

The first operating part 80 is located between the hook part 5 and the pressing part 7. The first operating part 80 includes a nut-shaped operating part 800 that is rotated and a tubular part 801 that is located closer to the hook part 5 than the operating part 800. In this embodiment, the operating part 800 and the tubular part 801 are separate members. The tubular part 801 is cylindrical, has a smooth inner surface, and is movable in the longitudinal direction of the jig body 4. The tubular part 801 moves when pressed by the operating part 800. The outer diameter of the tubular part 801 is larger than the diameter of the insertion hole 51 of the hook part 5.

In this embodiment, the operating part 800 is a hexagonal nut. The inner peripheral surface of the operating part 800 is provided with a screw thread that engages with the screw groove 400 of the jig body 4. The operating part 800 is rotated by a tool such as a power tool or a wrench.

The second operating part 81 is located on the opposite side of the hook part 5 to the first operating part 80. The second operating part 81 includes a nut-shaped operating part 810 that is rotated and a tubular part 811 that is located closer to the hook part 5 than the operating part 810. The tubular part 811 is cylindrical, has a smooth inner surface, and is movable in the longitudinal direction of the jig body 4. The tubular part 811 moves when pushed by the operating part 810. The outer diameter of the tubular part 811 is larger than the diameter of the insertion hole 51 of the hook part 5.

In this embodiment, the operating part 810 is a hexagonal nut. The inner peripheral surface of the operating part 810 is provided with a thread that engages with the thread groove 400 of the jig body 4. The operating part 810 is rotated by a tool such as a power tool or a wrench.

With the hook portion 5 fixed to the cross member 2, the pressing portion 7 can be slid in the longitudinal direction of the jig body 4 by rotating the first operating portion 80 or the second operating portion 81.

In more detail, the operating portion 800 of the first operating unit 80 is rotated in a direction approaching the hook portion 5 so that the operating portion 800, the cylindrical portion 801, and the hook portion 5 are in contact with each other, and from this state, the operating portion 800 is further rotated in the same direction, whereby the jig body 4 and the pressing portion 7 can be moved to the left by the rotation of the operating portion 800. In other words, by rotating the first operating unit 80, the pressing portion 7 can be moved in the longitudinal direction of the jig body 4 in a direction away from the hook portion 5 (to the left).

In addition, by rotating the operating portion 810 of the second operating unit 81 in a direction approaching the hook portion 5, the operating portion 810, the cylindrical portion 811, and the hook portion 5 are in contact with each other, and by further rotating the operating portion 810 in the same direction from this state, the jig body 4 and the pressing portion 7 can be moved to the right by the rotation of the operating portion 810. In other words, by rotating the second operating unit 81, the pressing portion 7 can be moved in the longitudinal direction of the jig body 4 in the direction approaching the hook portion 5 (to the right).

However, when rotating the second operating part 81, the operating part 800 and the cylindrical part 801 of the first operating part 80 are positioned away from the hook part 5 so as not to interfere with the movement of the jig body 4.

2-1-5. Pressing Part The pressing part 7 is configured to be able to press the accessory 30 of the panel 3 by being brought into contact with the accessory 30. In this embodiment, the pressing part 7 is in the shape of a substantially rectangular parallelepiped block, as shown in Fig. 4. The pressing part 7 has a similar structure to the hook part 5. Note that the pressing part 7 does not have a hole corresponding to the screw hole 520 of the hook part 5.

The pressing portion 7 has an engagement groove 70 into which a portion of the longitudinal direction of the vertical plate portion 20 of the cross member 2 can be inserted, and an insertion hole 71 into which one end (left end) of the rod-shaped member 40 is inserted. The engagement groove 70 is a groove that extends in the longitudinal direction of the jig body 4. The engagement groove 70 is open on each of the left and right faces and the bottom face of the pressing portion 7. In this embodiment, the pressing portion 7 is made of metal.

The pressing part 7 has a first vertical piece 72 having a rectangular parallelepiped shape with the vertical direction as the longitudinal direction, a horizontal piece 73 extending forward from the upper end of the first vertical piece 72, and a second vertical piece 74 having a rectangular parallelepiped shape extending downward from the front end of the horizontal piece 73. The first vertical piece 72 has an insertion hole 71 penetrating it in the left-right direction.

The second vertical piece 74 is parallel to the first vertical piece 72 and is located a distance away from the first vertical piece 72 that is approximately the same as the thickness of the vertical plate portion 20 of the cross member 2. The space surrounded by the first vertical piece 72, the horizontal piece 73, and the second vertical piece 74 is the locking groove 70 into which the vertical plate portion 20 is inserted.

The second vertical piece 74 has a first pressing surface 740 facing the hook portion 5 and a second pressing surface 741 facing the opposite side to the hook portion 5. The first pressing surface 740 or the second pressing surface 741 is pressed against the accessory part 30 of the panel 3.

The diameter of the insertion hole 71 is larger than the diameter of the jig body 4. A fastener 75 such as a nut is fixed to the portion surrounding the insertion hole 71 on the surface of the first vertical piece 72 facing away from the hook portion 5. One end of the jig body 4 in the longitudinal direction is inserted into the insertion hole 71, and one end of the jig body 4 in the longitudinal direction is fixed to the fastener 75. In this way, the pressing portion 7 is fixed to one end of the jig body 4 in the longitudinal direction. The insertion hole 71 may be a screw hole, in which case the fastener 75 can be omitted.

The pressing portion 7 is disposed in the same front-to-back position as the hook portion 5 with respect to the jig body 4. The front surface of the pressing portion 7 and the front surface of the hook portion 5 are located on the same plane or approximately on the same plane. Therefore, the panel position adjustment jig 1 of this embodiment has a reduced length in the front-to-back direction.

When the jig body 4 is moved by operating the slide operating unit 8, the pressing unit 7 moves in the longitudinal direction of the jig body 4 and presses the accessory part 30 of the panel 3 with the first pressing surface 740 or the second pressing surface 741.

2-2. Panel The panel 3 is a panel that is engaged with the cross member 2 so as to be slidable in its longitudinal direction, and has an accessory 30 fixed thereto. An example of the panel 3 is shown in Fig. 5. In this embodiment, the panel 3 is a sandwich panel that forms the wall of the building.

The panel 3 is a rectangular plate. The panel 3 has a longitudinal direction parallel to the vertical direction, a transverse direction parallel to the left-right direction, and a thickness direction parallel to the front-rear direction. For example, the length of the panel 3 in the vertical direction is 0.5 to 6.0 m, the length (width) in the left-right direction is 0.2 to 1.5 m, and the length (thickness) in the front-rear direction is 30 to 150 mm.

As shown in Figures 5, 6A, 6B and 7, the panel 3 comprises a core material 31, a first outer skin 32 that covers the core material 31 from the front side, and a second outer skin 33 that covers the core material 31 from the rear side.

The core material 31 has an overall rectangular plate shape. The overall plate shape is not limited to a single plate, but also includes multiple members arranged to form a single plate. The core material 31 has grooved rib sections 310 on the left and right side surfaces. The grooved rib sections 310 are located approximately in the center of the front-to-rear direction of the left and right side surfaces of the core material 31 over the entire length in the up-down direction. A fireproof joint material 11 (see Figure 8) made of a plate-shaped member such as a gypsum board or a calcium silicate board and a fibrous inorganic material such as an alkaline earth silicate blanket (biosoluble fiber) is inserted into the grooved rib sections 310.

The core material 31 has thermal insulation properties. The core material 31 is made by arranging a plurality of blocks of fibrous inorganic material such as rock wool or glass wool into blocks using a binder or the like, into a single rectangular plate. The core material 31 may be made of a foam-type organic material such as urethane foam or phenol foam, or may be a styrene board, urethane board, etc.

Each of the first outer skin 32 and the second outer skin 33 is obtained by forming a metal sheet into a desired shape by rolling, pressing, or the like. The metal sheet has a thickness of, for example, 0.23 to 6.0 mm. The metal sheet may be, but is not limited to, a painted steel sheet, a zinc-plated steel sheet, an aluminum-zinc alloy-plated steel sheet, a Galvalume steel sheet (registered trademark), an SGL (registered trademark) steel sheet, or the like.

Each of the four walls 321, 322, 323, and 324 is approximately perpendicular to the main body 320. Each of the upper and lower walls 321 and 322 is a rectangular flat plate. The left and right side walls 323 and 324 have rectangular flat plate portions 323a and 324a and rectangular plate-shaped protrusions 323b and 324b that protrude outward in the left-right direction at approximately right angles from the rear ends of the flat plate portions 323a and 324a.

The second skin 33 has a rectangular plate-shaped main body 330 that covers the rear surface of the core material 31, a left side wall 331 that covers the portion of the left side surface of the core material 31 rearward of the groove 310, and a right side wall 332 that covers the portion of the right side surface of the core material 31 rearward of the groove 310. The left side wall 331 protrudes forward from the left edge of the main body 330, and the right side wall 332 protrudes forward from the right edge of the main body 330. The second skin 33 does not have any portion that covers the top or bottom surface of the core material 31.

The left and right side walls 331, 332 each have a curved portion 331a, 332a that is curved in a U-shape when viewed from above, and a rectangular flat portion 331b, 332b that protrudes forward from the front end of the curved portion 331a, 332a.

The outer skins 32, 33 are integrated with the core material 31 by bonding the main body parts 320, 330 to the front and rear surfaces of the core material 31.

The panel 3 further includes packings 34 attached to each of the wall portions 321, 322, 323, and 324. Note that the packings 34 are not shown in FIG. 5. The packings 34 include a plurality of linear packings 340 and a plurality of L-shaped corner packings (not shown). As shown in FIG. 6A, FIG. 6B, and FIG. 7, the linear packings 340 are attached to the center of the upper surface of the upper wall portion 321 in the front-rear direction, the center of the lower surface of the lower wall portion 322 in the front-rear direction, and the rear end portions of the flat plate portions 323a and 324a of the left and right side wall portions 323 and 324. The packings 340 have a hollow semicircular cross section perpendicular to the longitudinal direction. The corner packings are attached to corner portions formed by two adjacent wall portions among the wall portions 321, 322, 323, and 324. The corner packings are solid L-shaped blocks. The packing 34 is provided in a rectangular frame shape when viewed from the front so as to surround the entire periphery of the panel 3. The packing 34 is made of, for example, synthetic rubber.

As shown in Figures 5 and 7, the panel 3 further includes a lower mounting member 35 that is fixed to the lower end of the rear surface of the panel 3 and is used for mounting to a cross member 2, and an upper mounting member 36 that is fixed to the upper end of the rear surface of the panel 3 and is used for mounting to another cross member 2.

The lower mounting member 35 is composed of three panel fixing plates 35a that are L-shaped in side view and are fixed to the lower end of the rear surface of the panel 3, and two mounting plates 35b that are roughly Z-shaped in side view and are fixed to the two panel fixing plates 35a at the left and right ends of the three panel fixing plates 35a by bolts 37. In this embodiment, the bolts 37 are bolts that can be fastened from one side.

The three panel fixing plates 35a are arranged at intervals in the left-right direction. Each of the three panel fixing plates 35a has a vertical piece 350 parallel to the rear surface of the panel 3, and a horizontal piece 351 extending forward from the lower end of the vertical piece 350 and parallel to the lower surface of the panel 3. The vertical piece 350 is fixed to the lower end of the main body portion 330 of the second outer skin 33 of the panel 3 with a fastener such as a screw, and the front end of the horizontal piece 351 is fixed to the lower wall portion 322 of the first outer skin 32 of the panel 3 with a fastener such as a screw.

The upper part of the mounting plate 35b is fixed with bolts 37 to the upper part of each vertical piece 350 of the two panel fixing plates 35a at the left and right ends, and an insertion groove 38 into which the vertical plate portion 20 of the cross member 2 can be inserted is formed between the lower part of the vertical piece 350 and the lower part of the mounting plate 35b. The width of the insertion groove 38 can be adjusted by the degree to which the bolts 37 are tightened. The mounting plate 35b can be pressed against the vertical plate portion 20 by tightening the bolts 37 all the way.

In this embodiment, one of the three panel fixing plates 35a constitutes the accessory part 30 against which the pressing part 7 of the panel position adjustment jig 1 is placed.

The upper mounting member 36 is composed of two panel fixing plates 36a that are L-shaped in side view and fixed to the upper end of the rear surface of the panel 3, and two rectangular mounting plates 36b that are fixed to each of the two panel fixing plates 36a with bolts 39.

The two panel fixing plates 36a are arranged at a distance in the left-right direction. The positions of the two panel fixing plates 36a in the left-right direction are the same as the two panel fixing plates 35a located at the left and right ends of the three panel fixing plates 35a. Each of the two panel fixing plates 36a has a vertical piece 360 parallel to the rear surface of the panel 3 and a horizontal piece 361 extending forward from the upper end of the vertical piece 360 and parallel to the upper surface of the panel 3. The vertical piece 360 is fixed to the upper end of the main body part 330 of the second outer skin 33 of the panel 3 with a fixing device such as a screw, and the front end of the horizontal piece 361 is fixed to the upper wall part 321 of the first outer skin 32 of the panel 3 with a fixing device such as a screw. The lower part of the mounting plate 36b is fixed to each vertical piece 360 of the two panel fixing plates 36a with a bolt 39.

The panel 3 is supported by the cross member 2 so that it can slide left and right by inserting the vertical plate portion 20 of the cross member 2 into the insertion groove 38 between the two mounting plates 35b and the two opposing panel fixing plates 35a, and hooking the two mounting plates 35b onto the vertical plate portion 20. At this time, the bolts 37 are screwed in a temporary holding state so that the mounting plates 35b do not come off the panel fixing plates 35a.

2-3. Horizontal member As shown in Fig. 9, the horizontal member 2 constitutes a part of the structural frame, and in this embodiment, it is an angle member that is L-shaped when viewed from the side. The horizontal member 2 is made of steel. The horizontal member 2 has a vertical plate portion 20 and a horizontal plate portion 21 that extends rearward from the lower end of the vertical plate portion 20. The thickness (length in the front-rear direction) of the vertical plate portion 20 is, for example, less than 10 mm, and preferably about 6 to 9 mm.

The structural framework includes a plurality of horizontal members 2 arranged vertically. Each of the plurality of horizontal members 2 is attached to a base 10 that constitutes the floor and ceiling of the building. Each of the plurality of horizontal members 2 may be fixed to a beam or may be fixed across a plurality of columns.

The multiple cross members 2 arranged vertically are spaced apart vertically by approximately the same distance as the upper and lower mounting members 35, 36 attached to the panel 3. Of the two cross members 2 arranged vertically, the upper cross member 2 has the upper mounting member 36 of the panel 3 attached to it, and the lower cross member 2 has the lower mounting member 35 of the panel 3 attached to it.

A support member 22 that is L-shaped in side view and supports the panel fixing plate 35a from below is fixed to the front of the vertical plate portion 20 of each cross member 2 by welding or the like. The support member 22 is L-shaped in side view and supports the panel fixing plate 35a from below.

3. Panel Position Adjustment Method Next, an example of a panel position adjustment method for adjusting the position of the panel 3 using the above-mentioned panel position adjustment jig 1 will be described. Below, a method for adjusting the position of the panel 3 on the side (right side) of a fixed panel 9 whose position is fixed relative to the structural frame (the cross member 2 in this embodiment) as shown in Fig. 8 will be described. In this embodiment, the fixed panel 9 is a sandwich panel having the same structure as the panel 3.

First, the panel 3 is placed to the side (right side) of the fixed panel 9 fixed to the cross member 2. At this time, the two mounting plates 35b at the lower end of the panel 3 are hooked onto the vertical plate portion 20 of the cross member 2. The mounting plates 35b are temporarily fixed to the panel fixing plate 35a with bolts 37, and the panel 3 is allowed to slide in the longitudinal direction of the cross member 2. The panel 3 is placed so that the packing 34 on the left side of the panel 3 abuts the packing 34 on the right side of the fixed panel 9. A fireproof joint material 11 is sandwiched between the fixed panel 9 and the panel 3. The position of the panel 3 is adjusted while it is lifted by a lifting means such as a crane.

Next, the vertical plate portion 20 of the cross member 2 is inserted into the insertion groove 50 of the hook portion 5 of the panel position adjustment jig 1 at the side (right side) of the panel fixing plate 35a at the right end of the panel 3, and the hook portion 5 is engaged with the vertical plate portion 20. At this time, the vertical plate portion 20 of the cross member 2 is inserted into the engagement groove 70 of the pressing portion 7 of the panel position adjustment jig 1, and the pressing portion 7 is engaged with the vertical plate portion 20. At this time, the second pressing surface 741 of the pressing portion 7 is positioned facing or against the right side surface of the panel fixing plate 35a at the right end of the panel 3.

Next, rotate the operating lever 61 of the fixed operation part 6 clockwise as viewed from the rear around the fixing bolt 60, so that the tip of the fixing bolt 60 of the fixed operation part 6 is pressed against the vertical plate part 20, and the hook part 5 is fixed to the vertical plate part 20.

Next, the operating portion 800 of the first operating part 80 of the slide operating part 8 is rotated in a direction approaching the hook part 5, and the pressing part 7 is slid to one side (left) in the longitudinal direction of the jig body 4. This causes the pressing part 7 to press the panel fixing plate 35a at the right end of the panel 3, causing the panel 3 to slide to the left.

Next, when the joint width between the panel 3 and the fixed panel 9 reaches a predetermined length, the rotation of the slide operation unit 8 is stopped. In this embodiment, the joint width between the panel 3 and the fixed panel 9 can be adjusted to a predetermined length by adjusting the position of the panel 3 with the panel position adjustment jig 1 as described above.

Once the panel 3 has been moved to the desired position, the panel 3 is fixed to the cross member 2. More specifically, the two mounting plates 36b of the upper mounting member 36 of the panel 3 are fixed to the vertical plate portion 20 of the upper cross member 2 by appropriate means such as welding.

Next, the two bolts 37 of the lower mounting member 35 of the panel 3 are screwed all the way in, and the two mounting plates 35b are pressed against the vertical plate portion 20 of the cross member 2. At this time, the panel fixing plate 35a located in the center in the left-right direction of the lower end of the panel 3 is placed on the receiving member 22 fixed to the vertical plate portion 20 of the cross member 2, and the weight of the panel 3 is supported by the receiving member 22. Note that the panel fixing plate 35a is not fixed to the receiving member 22 by welding or the like.

If another panel 3 is already installed below the panel 3, the vertical plate portion 20 of the cross member 2 and the mounting plate 36b of the other panel 3 are sandwiched between the two mounting plates 35b of the panel 3 and the opposing panel fixing plate 35a.

By doing the above, the panel 3 is fixed to the two cross members 2 at the top and bottom.

After the panel 3 has been fixed to the two upper and lower cross members 2, rotate the operating lever 61 of the fixing operating part 6 of the panel position adjustment jig 1 to release the hook part 5 from the vertical plate part 20, remove the hook part 5 and the pressure part 7 from the vertical plate part 20, and remove the panel position adjustment jig 1 from the horizontal member 2.

By carrying out the construction as described above, the panel 3 is fixed to the cross member 2 with a specified joint width formed between it and the fixed panel 9. By fixing multiple panels 3 to the cross member 2 using the construction method described above, it is possible to form a wall structure such as that shown in Figure 9.

4. Effects and Effects The panel position adjustment jig 1 of the present embodiment described above can fix the hook portion 5 to the cross member 2 by operating the fixing operation unit 6 in a state in which the hook portion 5 is engaged with the cross member 2 on the side of the panel fixing plate 35a (accessory part 30) of the panel 3 slidably engaged with the cross member 2. Thereafter, the slide operation unit 8 can be operated to slide the pressing unit 7, which presses the accessory part 30 of the panel 3 to slide the panel 3, thereby adjusting the position of the panel 3.

In this way, with the panel position adjustment jig 1 of this embodiment, the pressing portion 7 can be brought into contact with the accessory part 30 to slide the panel 3, thereby preventing scratches on the panel 3 (particularly the outer skins 32, 33).

In addition, the panel position adjustment jig 1 of this embodiment has a first operating part 80 and a second operating part 81 as the slide operating part 8, so the position of the pressing part 7 can be changed as appropriate, making it easy to adjust the position of the panel 3.

In addition, in the panel position adjustment jig 1 of this embodiment, the pressing part 7 can be moved with the vertical plate part 20 inserted into the locking groove 70 of the pressing part 7, so the front-to-rear position of the pressing part 7 during movement is easily stabilized, and the pressing part 7 can be easily applied to the side of the accessory part 30 of the panel 3.

In addition, in the panel position adjustment jig 1 of this embodiment, the operating parts 80, 81 of the slide operating part 8 have nut-shaped operating parts 800, 810, so the position of the pressing part 7 can be adjusted steplessly, making it easy to adjust the position of the panel 3.

In addition, in the panel position adjustment jig 1 of this embodiment, the nut-shaped operating parts 800, 810 are located at least the length of the cylindrical parts 801, 811 away from the hook part 5, making it easy to rotate the operating parts 800, 810.

In addition, in the panel position adjustment jig 1 of this embodiment, the jig body 4, the hook portion 5, the slide operation portion 8, and the pressing portion 7 are all contained within a predetermined width in the front-rear direction, making it compact in the front-rear direction.

5. Modifications Modifications of the panel position adjustment jig 1 and the panel position adjustment method according to the present embodiment described above will be described.

As a method for adjusting the panel position, as shown in the modified example in FIG. 10, the jig body 4 may be placed in a position facing the joint between the panel 3 and the fixed panel 9 to adjust the position of the panel 3. In this modified example, the position of the panel 3 is adjusted using a panel position adjustment jig 1 in which the hook portion 5 and the pressing portion 7 are arranged in reverse order. The pressing portion 7 is fixed to the right end of the jig body 4, and the hook portion 5 is attached to the left part of the jig body 4.

In this modified example, the panel position adjustment jig 1 is arranged so that the first pressing surface 740 of the pressing unit 7 faces the right side surface of the panel fixing plate 35a at the left end of the panel 3, and the operating portion 810 of the second operating unit 81 of the slide operating unit 8 is rotated in a direction approaching the hook portion 5 to slide the pressing unit 7 to one side (left) in the longitudinal direction of the jig body 4. This allows the pressing unit 7 to press the panel fixing plate 35a at the left end of the panel 3, causing the panel 3 to slide to the left.

In the modified panel position adjustment method, the panel position adjustment jig 1 can be operated at a position facing the joint between the panel 3 and the fixed panel 9, making it easy to adjust the joint width to a specified length.

The panel position adjustment jig 1 may be used in other ways, not limited to the ways shown in Figures 8 and 10. The pressing portion 7 of the panel position adjustment jig 1 may press the central panel fixing plate 35a among the three panel fixing plates 35a. The panel position adjustment jig 1 can also use the first pressing surface 740 and the second pressing surface 741 as appropriate, depending on the direction in which the panel 3 is to be moved.

The panel position adjustment jig 1 may also be used to adjust the position of the panel 3 for other purposes, not just to adjust the joint width between the panel 3 and the fixed panel 9.

The accessory part 30 of the panel 3 is not limited to any one of the three panel fixing plates 35a at the lower end of the panel 3, but may be any one of the two panel fixing plates 36a at the upper end of the panel 3, or may be another part fixed to the panel 3.

The jig body 4 is not limited to a rod-shaped member 40 having a thread groove 400 on its outer circumferential surface. For example, the jig body 4 may be a rod-shaped member that does not have a thread groove 400, and may be any member that can slide relative to the hook portion 5 fixed to the cross member 2.

The slide operation unit 8 may be configured to slide the pressing unit 7 in the longitudinal direction of the cross member 2, and is not limited to the structure shown in FIG. 1, etc. For example, the slide operation unit 8 is not limited to a unit that slides while rotating, and may be a unit that slides without rotating.

The slide operation unit 8 may also have only one of the first operation unit 80 and the second operation unit 81.

Furthermore, each of the operating units 80, 81 may have only the operating portion 800, 810 out of the operating portion 800, 810 and the cylindrical portion 801, 811.

In addition, the operating parts 80 and 81 may each have the operating portion 800, 810 and the cylindrical portion 801, 811 provided integrally rather than separately.

The pressing portion 7 does not need to have a locking groove 70, but only needs to be configured so that it can come into contact with and press against the accessory part 30 of the panel 3.

In addition, panel 3 is not limited to the sandwich panel having the structure shown in Figures 5 to 7. Panel 3 is not limited to a sandwich panel having a metal outer skin, and may be a ceramic panel, a metal siding material, or a wooden panel, and is not particularly limited.

The fixed panel 9 may be a panel of a different shape and size than the panel 3. The fixed panel 9 may also be fixed in position relative to a structural body other than the cross member 2 to which the panel 3 is hooked.

The cross member 2 is not limited to an angle member that is L-shaped when viewed from the side, but may be composed of only a vertical plate portion 20.

The fixing operation unit 6 may be configured to be able to fix the hook portion 5 to the cross member 2, and is not limited to the structure shown in FIG. 1, etc. For example, the fixing operation unit 6 may not have an operating lever 61, and may be configured only with the fixing bolt 60. In this case, the hook portion 5 can be fixed and released from the cross member 2 by rotating the head 63 of the fixing bolt 60 with a tool such as a power tool or a wrench.

Second Embodiment
1. Details Next, the panel position adjustment jig 1 of the second embodiment will be described with reference to Fig. 11. Note that the basic configuration and construction method of the panel position adjustment jig 1 of the present embodiment are common to those of the first embodiment, and therefore, the same reference numerals will be used in the drawings to denote the same parts as those of the first embodiment, and the description will be omitted.

In the panel position adjustment jig 1 of this embodiment, the slide operation unit 8 is composed of one operation unit (specifically, the second operation unit 81). The slide operation unit 8 is rotatably attached to the jig body 4 on the opposite side of the pressing unit 7 with respect to the hook unit 5. The slide operation unit 8 of this embodiment does not include the first operation unit 80 (see FIG. 1).

In the panel position adjustment jig 1 of this embodiment, the operating part 810 of the slide operating unit 8 is rotated in a direction approaching the hook portion 5 (left side) to bring the operating part 810, the cylindrical part 811 and the hook portion 5 into contact with each other, and from this state, the operating part 810 is further rotated in the same direction, whereby the jig body 4 and the pressing part 7 can be moved to the right by the rotation of the operating part 810. In other words, by rotating the slide operating unit 8, the pressing part 7 can be moved in the longitudinal direction of the jig body 4 in a direction approaching the hook portion 5 (right side), and the panel 3 can be moved to the right.

The panel position adjustment jig 1 of this embodiment described above has fewer parts and is easier to manufacture than the panel position adjustment jig 1 of the first embodiment. In addition, the position adjustment jig 1 of this embodiment has the slide operation part 8 attached to the part of the jig body 4 opposite the pressing part 7 with respect to the hook part 5 (one end of the jig body 4 in the longitudinal direction), so that the slide operation part 8 can be easily rotated with a tool such as a ratchet wrench.

The panel position adjustment jig 1 of the second embodiment described above can also be appropriately combined with the above-mentioned modified examples of the panel position adjustment jig 1 of the first embodiment. In addition, the following modified examples can also be appropriately combined.

The thread groove 400 on the outer peripheral surface of the jig body 4 may be threaded in the opposite direction to that of this embodiment. In this case, when the operating portion 810 of the slide operating unit 8 is rotated in a direction approaching the hook portion 5 (left side), the jig body 4 and the pressing unit 7 can be moved to the left. In other words, by rotating the second operating unit 81, the pressing unit 7 can be moved in the longitudinal direction of the jig body 4 in a direction away from the hook portion 5 (left side), and the panel 3 can be moved to the left.

Also, as in the modified example shown in FIG. 12, the arrangement of the pressing part 7 and the hooking part 5 on the jig body 4 may be reversed. In this modified example, the pressing part 7 is fixed to the right end of the jig body 4, and the hooking part 5 and the slide operation part 8 are attached to the left part of the jig body 4.

In this modified panel position adjustment jig 1, the operating portion 810 of the slide operating unit 8 can be rotated in a direction approaching the hook portion 5 (to the right) to move the jig body 4 and the pressing portion 7 to the left, thereby moving the panel 3 to the left.

The panel position adjustment jig 1 may have two parts: one with the pressing part 7 fixed to the left end of the jig body 4 (the jig body 4 and pressing part 7 of the second embodiment), and one with the pressing part 7 fixed to the right end of the jig body 4 (the jig body 4 and pressing part 7 of the modified example), and the hook part 5, fixed operation part 6, and slide operation part 8 may be attached to one selected from the two. In this case, the structure of the panel position adjustment jig 1 can be changed according to the conditions of use.
