Description

[Technical Field]

[0001] The present disclosure relates to a joint width adjusting jig for adjusting the joint width between panels and a joint width adjusting method using the same. [Background technology]

[0002] Patent Document 1 describes a joint width adjusting jig that adjusts the joint width between two panels arranged side by side.

[0003] The joint width adjustment jig is equipped with a locking piece for locking onto the outer end of one panel, a pressing piece for pressing against the outer end of the other panel, and an operating part for moving the pressing piece. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-172347 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the joint width adjustment jig described in Patent Document 1 is long and spans the entire length of the two panels, so there is room for improvement in terms of ease of handling. Also, because the operating part of this joint width adjustment jig is separated from the joint between the two panels, a single installer needs to move between the joint and the operating part multiple times in order to adjust the joint width.

[0006] Furthermore, to ensure that the joint width between the two panels was the specified size, it was necessary to measure the joint width with a ruler every time the panels were moved, making adjustment of the joint width time-consuming. In particular, when the surface and side of the panels are joined at an arc-shaped corner rather than at a right angle, it is difficult to measure the distance between the sides of the two panels (i.e., the joint width), making adjustment of the joint width time-consuming.

[0007] In view of the above circumstances, the present disclosure aims to propose a joint width adjustment jig that is easy to handle and allows for easier adjustment of the joint width between panels, and a joint width adjustment method using the same. [Means for solving the problem]

[0008] A joint width adjustment jig according to one aspect of the present disclosure is a joint width adjustment jig for adjusting the joint width between a first panel and a second panel. This joint width adjustment jig includes a jig body elongated in one direction, a first hooking portion, a movable portion, a second hooking portion, an operating portion, and a joint forming portion. The first hooking portion is integrally formed with the jig body and configured to hook onto an end of the first panel adjacent to the second panel. The movable portion is attached to the jig body and is movable along the longitudinal direction of the jig body. The second hooking portion is integrally formed with the movable portion and configured to hook onto an end of the second panel adjacent to the first panel. The operating portion is attached to the jig body and can move the movable portion. The joint forming portion is attached to the jig body and can be sandwiched between the first panel and the second panel.

[0009] A joint width adjusting method according to one aspect of the present disclosure is a joint width adjusting method for adjusting the joint width between the first panel and the second panel using the joint width adjusting jig. In this joint width adjusting method, the first hooking portion is hooked onto an end of the first panel adjacent to the second panel, and the second hooking portion is hooked onto an end of the second panel adjacent to the first panel. In this joint width adjusting method, the operating portion is then operated to move the movable portion and the second hooking portion, thereby sandwiching the joint forming portion between the first panel and the second panel and setting the joint width between the first panel and the second panel to a predetermined width. [Effects of the Invention]

[0010] In the joint width adjusting jig and joint width adjusting method using the same according to one aspect of the present disclosure, the joint width adjusting jig is easy to handle, making it easier to adjust the joint width between panels. [Brief explanation of the drawings]

[0012] 1. Overview The joint width adjusting jig 1 of one embodiment shown in FIGS. 1 and 2 is for adjusting the joint width between a first panel P1 and a second panel P2. As shown in FIG. 2, the joint width adjusting jig 1 includes a jig main body 2 that is elongated in one direction, a first hooking portion 3, a movable portion 4, a second hooking portion 5, an operating portion 6, and a joint forming portion 17. The first hooking portion 3 is integrally formed with the jig main body 2 and configured to hook onto the end of the first panel P1 adjacent to the second panel P2. The movable portion 4 is attached to the jig main body 2 and is movable along the longitudinal direction of the jig main body 2. The second hooking portion 5 is integrally formed with the movable portion 4 and configured to hook onto the end of the second panel P2 adjacent to the first panel P1. The operating portion 6 is attached to the jig main body 2 and can move the movable portion 4. The joint forming portion 17 can be sandwiched between the first panel P1 and the second panel P2.

[0013] In one embodiment of the joint width adjustment jig 1 having the above configuration, the jig 1 itself can be formed to a short length spanning the adjacent ends of panels P1 and P2, making it easy to handle. Furthermore, in one embodiment of the joint width adjustment jig 1, the hooks 3 and 5 can be hooked onto the adjacent ends of panels P1 and P2, allowing the operating unit 6 to be operated from a position close to the joint between panels P1 and P2. This reduces the need for movement between the operating position of the operating unit 6 and the joint width confirmation position. Furthermore, in one embodiment of the joint width adjustment jig 1, the joint forming unit 17 attached to the jig body 2 can be sandwiched between panels P1 and P2 to set the joint width between panels P1 and P2 to a predetermined width, eliminating the need to measure the joint width with a ruler. This makes it easier to adjust the joint width between panels P1 and P2 with the joint width adjustment jig 1 in one embodiment.

[0014] A joint width adjusting method according to one embodiment of the present disclosure is a joint width adjusting method for adjusting the joint width between a first panel P1 and a second panel P2 using the joint width adjusting jig 1. In this joint width adjusting method, the first hooking portion 3 is hooked onto the end of the first panel P1 adjacent to the second panel P2, and the second hooking portion 5 is hooked onto the end of the second panel P2 adjacent to the first panel P1. Thereafter, in this joint width adjusting method, the operating portion 6 is operated to move the movable portion 4 and the second hooking portion 5, sandwiching the joint forming portion 17 between the first panel P1 and the second panel P2 and setting the joint width between the first panel P1 and the second panel P2 to a predetermined width.

[0015] In the joint width adjustment method of one embodiment having the above configuration, the operating unit 6 can be operated at a position close to the joint between the panels P1 and P2, movement between the operating position of the operating unit 6 and the joint width confirmation position can be suppressed, and a joint of a predetermined width can be formed between the panels P1 and P2 simply by clamping the joint forming unit 17. Therefore, in the joint width adjustment method of one embodiment, adjustment of the joint width between the panels P1 and P2 can be more easily performed.

[0016] 2.Details Next, the joint width adjusting jig 1 of one embodiment shown in Figs. 1 and 2 and the joint width adjusting method using the same will be described in more detail.

[0017] In this specification, the direction in which panels P1 and P2 are arranged is referred to as the left-right direction, the thickness direction of panels P1 and P2 is referred to as the front-back direction, and the direction perpendicular to the left-right and front-back directions is referred to as the up-down direction, and each configuration will be described in detail.

[0018] 2-1.Joint width adjustment jig As shown in Figures 3 and 4, the joint width adjustment jig 1 comprises a jig body 2, a first hooking portion 3, a movable portion 4, a second hooking portion 5, an operating portion 6, a gripping portion 7, and a joint forming portion 17.

[0019] 2-1-1. Jig body The jig body 2 is a rod-shaped member that is long in the left-right direction (i.e., in one direction). In this embodiment, the jig body 2 has a circular cross section perpendicular to the longitudinal direction and is in the shape of a round rod. The jig body 2 is made of, for example, stainless steel.

[0020] A screw groove 20 is formed on the outer periphery of a portion of the jig body 2 in the longitudinal direction. In this embodiment, the screw groove 20 is formed over the entire portion of the jig body 2 to the left of the center in the left-right direction. The screw groove 20 has a trapezoidal thread shape. Therefore, a portion of the jig body 2 in the longitudinal direction is a trapezoidal thread. This makes the screw thread less likely to be crushed, which tends to improve durability. Furthermore, even if the jig 1 is dropped, the screw thread is less likely to be damaged. Note that the shape of the screw thread is not limited to a trapezoid and may be other shapes.

[0021] 1 and 2, the left-right length of the jig body 2 extends from the left end of the panel P1 (the end on the panel P2 side) to the right end of the panel P2 (the end on the panel P1 side). The left-right length of the jig body 2 is, for example, about 350 mm.

[0022] 2-1-2. First hook The first hook portion 3 is formed integrally with the jig body 2, and is configured to hook onto the end of the first panel P1 adjacent to the second panel P2 (in this embodiment, the edge of the mounting hole 112 in the upper plate 110b fixed to the first panel P1). As shown in Figures 3 and 4, in this embodiment, the first hook portion 3 is provided on the right end of the jig body 2. The first hook portion 3 protrudes from the right end of the jig body 2 at a right angle to the jig body 2. The first hook portion 3 protrudes downward from the right end of the jig body 2.

[0023] The first hooking portion 3 is a rod-shaped member. In this embodiment, the first hooking portion 3 has a circular cross section perpendicular to the longitudinal direction and is rod-shaped. The first hooking portion 3 is formed of, for example, stainless steel. The jig body 2 and the first hooking portion 3 are formed, for example, by bending a single rod-shaped member.

[0024] The first hooking portion 3 has a base portion 30, a tip portion 31, and an intermediate portion 32, each having a different diameter. The upper portion of the first hooking portion 3 is the base portion 30, the lower end portion of the first hooking portion 3 is the tip portion 31, and the portion of the first hooking portion 3 between the base portion 30 and the tip portion 31 is the intermediate portion 32. The base portion 30 has a larger diameter than the intermediate portion 32 and the tip portion 31, and the tip portion 31 has a larger diameter than the intermediate portion 32.

[0025] A plate-shaped reinforcing member 33 is attached by welding or the like to the inner corner formed by the base 30 and the jig body 2. A taper 310 is provided on the tip side of the outer peripheral surface of the tip 31, and the diameter of the tip 31 becomes smaller as it approaches the tip (lower end).

[0026] 2-1-3. Moving parts The movable part 4 is attached to the jig body 2 and is movable along the longitudinal direction of the jig body 2. In this embodiment, the movable part 4 is a cylindrical member through which the jig body 2 passes. The movable part 4 is made of, for example, stainless steel.

[0027] The movable part 4 is cylindrical, and its inner diameter is slightly larger than the outer diameter of the jig body 2. The movable part 4 is passed through a portion of the jig body 2 to the left of the gripping part 7. The movable part 4 is movable left and right in the portion of the jig body 2 to the left of the gripping part 7. The movable part 4 is rotatable around the axis of the jig body 2 relative to the jig body 2.

[0028] 2-1-4. Second hook As shown in Figure 2, the second hook portion 5 is integrally formed with the movable portion 4 and is configured to hook onto the end portion of the second panel P2 adjacent to the first panel P1 (in this embodiment, the edge of the mounting hole 112 of the upper plate 110b fixed to the second panel P2).

[0029] 3 and 4, the second hook portion 5 is a rod-shaped member. In this embodiment, the second hook portion 5 has a circular cross section perpendicular to the longitudinal direction, and is a round rod-shaped member. The second hook portion 5 is made of, for example, stainless steel.

[0030] The second hook portion 5 protrudes from the center of the movable portion 4 in the left-right direction in a direction perpendicular to the axial direction (i.e., the left-right direction) of the movable portion 4. In this embodiment, the second hook portion 5 protrudes downward from the movable portion 4.

[0031] The second hooking portion 5 has a common structure with the first hooking portion 3. More specifically, the second hooking portion 5 has a base portion 50, a tip portion 51, and an intermediate portion 52, each of which has a different diameter. The upper portion of the second hooking portion 5 is the base portion 50, the lower end portion of the second hooking portion 5 is the tip portion 51, and the portion of the second hooking portion 5 between the base portion 50 and the tip portion 51 is the intermediate portion 52. The base portion 50 has a larger diameter than the intermediate portion 52 and the tip portion 51, and the tip portion 51 has a larger diameter than the intermediate portion 52. A taper 510 is provided on the tip side of the outer peripheral surface of the tip portion 51, and the diameter of the tip portion 51 decreases toward the tip side (lower end).

[0032] The second hook portion 5 is parallel to the first hook portion 3. The lower surface of the base portion 50 of the second hook portion 5 and the lower surface of the base portion 30 of the first hook portion 3 are positioned at the same vertical position. The middle portion 52 of the second hook portion 5 and the middle portion 32 of the first hook portion 3 have the same vertical length. The upper surface of the tip portion 51 of the second hook portion 5 and the upper surface of the tip portion 31 of the first hook portion 3 are positioned at the same vertical position.

[0033] 2-1-5.Operation section The operating part 6 is attached to the jig body 2 and is capable of moving the movable part 4. In this embodiment, the operating part 6 is a nut rotatably attached to the thread groove 20 of the jig body 2. More specifically, the operating part 6 is a hexagonal nut, and an internal thread that engages with the thread groove 20 is formed on its inner peripheral surface.

[0034] As shown in FIG. 5, the operating unit 6 can be rotated manually or electrically using a tool 8 such as a wrench.

[0035] 2-1-6.Gripping part 3 and 4, the gripping portion 7 is integrally formed with the jig body 2 and is located on a different side of the jig body 2 from the first hooking portion 3. The gripping portion 7 is a portion that can be grasped by an operator with one hand.

[0036] In this embodiment, the gripping portion 7 is an L-shaped member. The gripping portion 7 is integral with the right end portion of the jig body 2 and is located adjacent to the left side of the first hooking portion 3 in the left-right direction.

[0037] In this embodiment, the gripping portion 7 is located on the opposite side of the jig body 2 from the first hooking portion 3. In other words, the gripping portion 7 protrudes upward from the jig body 2.

[0038] The gripping portion 7 has a main body 70 that is parallel to the jig body 2 and positioned away from the jig body 2, and a connecting portion 71 that extends at a right angle from one end (the right end in this embodiment) of the main body 70 in the longitudinal direction (i.e., the left-right direction). The main body 70 and the connecting portion 71 are each shaped like a round bar. The tip end (lower end) of the connecting portion 71 is fixed to the jig body 2.

[0039] The gripping portion 7 is formed, for example, by bending a round bar-shaped member, and is fixed to the jig body 2 by welding. The gripping portion 7 is made of, for example, stainless steel.

[0040] 2-1-7. Joint forming part As shown in FIG. 2, the joint forming part 17 is a member that is attached to the jig body 2 and can be sandwiched between the first panel P1 and the second panel P2.

[0041] 3 and 4, the joint forming part 17 is attached to the jig body 2 so as to be movable in the longitudinal direction of the jig body 2. The joint forming part 17 is also attached to the jig body 2 so as to be rotatable around the jig body 2. The joint forming part 17 is made of, for example, a synthetic resin. Note that the joint forming part 17 is not limited to being made of synthetic resin, and may be made of aluminum, as long as it is made of a material hard enough to not be crushed when sandwiched between the panels P1 and P2.

[0042] The joint forming portion 17 has an arm portion 170 whose one longitudinal end is rotatably attached to the jig body 2, and a first joint forming portion 171 and a second joint forming portion 172 which extend in opposite directions from the other longitudinal end of the arm portion 170.

[0043] In this embodiment, the joint forming portion 17 is a T-shaped member. The arm portion 170 is rod-shaped (specifically, square rod-shaped) extending in one direction. One longitudinal end of the arm portion 170 is provided with an attachment hole 173 through which the jig body 2 passes. A first joint forming portion 171 and a second joint forming portion 172 extend in opposite directions from the other longitudinal end of the arm portion 170.

[0044] Each of the first joint forming portion 171 and the second joint forming portion 172 is a rod-like shape (more specifically, a square rod-like shape) extending in one direction. The longitudinal direction of each of the first joint forming portion 171 and the second joint forming portion 172 intersects with the longitudinal direction of the arm portion 170, and in this embodiment, is perpendicular to the longitudinal direction of the arm portion 170. The arm portion 170, the first joint forming portion 171, and the second joint forming portion 172 are connected in a T-shape.

[0045] 5, the first joint forming portion 171 and the second joint forming portion 172 have the same lengths L1 and L2 in the longitudinal direction (i.e., left-right direction) of the jig body 2. The lengths L1 and L2 are, for example, 20 mm. The lengths L1 and L2 are set to the same length as the width (left-right length) of the joint to be formed between the panels P1 and P2.

[0046] 3 and 4, the joint forming part 17 is movably and rotatably attached to the jig body 2 by passing the jig body 2 through the attachment hole 173 of the arm part 170. The joint forming part 17 is attached to a part of the jig body 2 between the connecting part 71 of the gripping part 7 and the movable part 4. The joint forming part 17 is slidable in the longitudinal direction of the jig body 2 in the part of the jig body 2 between the connecting part 71 and the movable part 4. The joint forming part 17 is rotatable around the central axis of the jig body 2.

[0047] The joint forming part 17 is prevented from coming off and falling off one end (left end) of the jig body 2 in the longitudinal direction by the movable part 4 and the operating part 6 (nut).

[0048] The joint forming portion 17 can be moved in the longitudinal direction of the jig body 2 and rotated around the central axis of the jig body 2, so that either the first joint forming portion 171 or the second joint forming portion 172 can be sandwiched between the panels P1 and P2 in accordance with the orientation of the jig 1 when in use. As a result, a joint of a predetermined width and having the same length as the lengths L1 and L2 of the joint forming portions 171 and 172 is formed between the panels P1 and P2.

[0049] In this embodiment, the joint forming portion 17 is made of synthetic resin, and therefore is unlikely to scratch the surfaces of the panels P1 and P2 when being pulled out from between the panels P1 and P2.

[0050] 2-2. First and second panels The first panel P1 and the second panel P2 shown in Fig. 1 are panels that are fixed to a building skeleton 10 to form the walls of the building. In this embodiment, the first panel P1 and the second panel P2 have a common structure and are made of a sandwich panel 9 shown in Fig. 6.

[0051] As shown in FIGS. 6, 7A, 7B, and 8, the sandwich panel 9 has a pair of metal skins 90, 91 and a core material 92 located between the pair of metal skins 90, 91.

[0052] The sandwich panel 9 is a rectangular plate. The sandwich panel 9 has a longitudinal direction parallel to the up-down direction, a lateral direction parallel to the left-right direction, and a thickness direction parallel to the front-rear direction. The sandwich panel 9 has, for example, a length in the up-down direction of 0.5 to 6.0 m, a length (width) in the left-right direction of 0.2 to 1.5 m, and a length (thickness) in the front-rear direction of 50 to 150 mm.

[0053] The core material 92 has thermal insulation properties. The core material 92 is, for example, a rectangular plate formed by arranging a plurality of blocks of fibrous inorganic material, such as rock wool or glass wool, bound together with a binder or the like. The core material 92 may be formed of a foam-type organic material, such as urethane foam or phenol foam, or may be a styrene board or urethane board. Recesses 920 are provided on the left and right end surfaces of the core material 92. A fire-resistant material 95 is disposed in one of the left and right recesses 920 (the left recess 920 in this embodiment). The fire-resistant material 95 has higher fire resistance than the core material 92. The fire-resistant material 95 is formed, for example, from a gypsum board or a calcium silicate board and a fire-resistant felt, such as rock wool felt.

[0054] Each of the pair of metal skins 90, 91 is obtained by forming a metal plate into a desired shape by rolling, pressing, etc. The metal plate has a thickness of, for example, 0.23 to 6.0 mm. The metal plate may be, but is not limited to, a painted steel plate, a zinc-plated steel plate, an aluminum-zinc alloy-plated steel plate, a Galvalume steel plate (registered trademark), an SGL (registered trademark) steel plate, etc.

[0055] Of the pair of metal outer skins 90, 91, the metal outer skin 90 located on the front side has a rectangular box shape that opens toward the rear. The metal outer skin 90 has a rectangular plate-shaped main body 900 that covers the front side of the core material 92, an upper wall 901 that covers the front portion of the upper surface of the core material 92, a lower wall 902 that covers the front portion of the lower surface of the core material 92, and left and right side wall parts 903 that cover the portions of the left and right side surfaces of the core material 92 that are forward of recesses 920. The main body 900 and the left and right side wall parts 903 are continuous, forming arc-shaped corners rather than right angles. Therefore, the surface (front surface) of the main body 900 and the surfaces (side surfaces) of the left and right side wall parts 903 are continuous, forming arc-shaped corners.

[0056] Of the pair of metal skins 90, 91, the metal skin 91 located on the rear side has a rectangular plate-shaped main body 910 that covers the rear surface of the core material 92, and left and right side wall portions 911 that cover the rear portions of the left and right side surfaces of the core material 92. Note that the metal skin 91 does not have any portions that cover the upper or lower surface of the core material 92.

[0057] The metal skins 90 and 91 are integrated with the core material 92 by having the main body portions 900 and 910 bonded to the front and rear surfaces of the core material 92, respectively.

[0058] As shown in FIGS. 6 and 8, the sandwich panel 9 is a panel to which a fixing member 11 and a second fixing member 12 are attached, the fixing member 11 being used for fixing the sandwich panel 9 to a body 10.

[0059] The fixing member 11 includes a fixing plate 110 fixed to the sandwich panel 9, and a mounting plate 111 connected to the fixing plate 110 and having a portion thereof protruding upward beyond the sandwich panel 9. In this embodiment, the mounting plate 111 is bolted to the fixing plate 110.

[0060] The fixing plate 110 is an L-shaped member when viewed from the side. The fixing plate 110 is formed, for example, by bending a steel plate that is thicker than the metal outer skins 90, 91. The fixing plate 110 has a rear plate 110a that fits along the rear surface of the sandwich panel 9, and an upper plate 110b that extends forward from the upper end of the rear plate 110a and fits along the upper surface of the sandwich panel 9. The rear plate 110a and the upper plate 110b are each rectangular. The rear plate 110a is fixed to the upper end of the main body 910 of the metal outer skin 91 of the sandwich panel 9 with fasteners such as screws (not shown). The front end of the upper plate 110b is fixed to the upper wall portion 901 of the metal outer skin 90 of the sandwich panel 9 with fasteners such as screws (not shown).

[0061] The rear plate 110a is provided with fixing holes into which bolts 93 are fastened to fasten the mounting plate 111 to the fixed plate 110. In this embodiment, the bolts 93 can be fastened from one side and have a loosening prevention function. The upper plate 110b is provided with fixing holes 112. The fixing holes 112 penetrate the upper plate 110b in the vertical direction (thickness direction).

[0062] The mounting hole 112 is a hole into which the first hook portion 3 or the second hook portion 5 can be inserted. The mounting hole 112 has a smaller diameter than the base portions 30, 50 of the hook portions 3, 5, and a larger diameter than the tip portions 31, 51 and middle portions 32, 52 of the hook portions 3, 5. The thickness of the upper plate 110b is the same as or slightly smaller than the vertical length of the middle portions 32, 52 of the hook portions 3, 5.

[0063] In this embodiment, as shown in FIG. 9, the mounting holes 112 are holes to which a lifting tool 13 can be attached and detached, which is used when lifting the panels P1, P2 with a lifting device such as a crane.

[0064] The mounting plate 111 has a rectangular plate shape. The mounting plate 111 is formed, for example, from a steel plate that is thicker than the metal outer skins 90, 91. An insertion hole into which a bolt 93 is inserted is provided in the lower part of the mounting plate 111. The lower part of the mounting plate 111 is fixed to the rear plate 110a of the fixing plate 110 with the bolt 93, and the upper part of the mounting plate 111 protrudes above the upper surface of the sandwich panel 9. The part of the mounting plate 111 that is located above the upper plate 110b of the fixing plate 110 is the part that is fixed to the frame 10. The bolt 93 penetrates the main body 910 of the metal outer skin 91 of the sandwich panel 9, and its tip is embedded in the core material 92.

[0065] In this embodiment, the fixing member 11 includes fixing plates 110 attached to the left and right ends of the upper end of the sandwich panel 9, respectively, and mounting plates 111 fixed to the left and right fixing plates 110 with bolts 93. The distance from the left fixing plate 110 to the left end of the sandwich panel 9 is the same as the distance from the right fixing plate 110 to the right end of the sandwich panel 9. The left and right fixing plates 110 are attached to the sandwich panel 9 so that they are approximately the same distance from the left and right ends of the sandwich panel 9, regardless of the width dimension of the sandwich panel 9. Therefore, the distance between the mounting holes 112 of adjacent fixing plates 110 of two laterally adjacent sandwich panels 9 is approximately constant, regardless of the width dimension of the sandwich panel 9.

[0066] The second fixing member 12 includes a fixing plate 120 fixed to the lower end of the sandwich panel 9 and an attachment plate 121 attached to the fixing plate 120 with a bolt 93. In this embodiment, the bolt 93 can be fastened from one side and has a loosening prevention function. In this embodiment, the second fixing member 12 includes three fixing plates 120 positioned at a distance in the left-right direction and two attachment plates 121 bolted to two of the three fixing plates 120 located at the left and right ends. Of the three fixing plates 120, the two fixing plates 120 located at the left and right ends are positioned in the same left-right direction as the left and right fixing plates 110. Of the three fixing plates 120, the fixing plate 120 located in the center in the left-right direction is located at the center of the sandwich panel 9 in the left-right direction.

[0067] The fixing plate 120 is an L-shaped member in a side view. The fixing plate 120 is formed, for example, by bending a steel plate that is thicker than the metal outer skins 90, 91. The fixing plate 120 includes a rear plate 120a that fits along the rear surface of the sandwich panel 9 and a lower plate 120b that extends forward from the lower end of the rear plate 120a and fits along the lower surface of the sandwich panel 9. The rear plate 120a and the lower plate 120b are each rectangular. The rear plate 120a is fixed to the lower end of the main body 910 of the metal outer skin 91 of the sandwich panel 9 with a fastener (not shown) such as a screw. The lower plate 120b has its front end fixed to the lower wall portion 902 of the metal outer skin 90 of the sandwich panel 9 with a fastener (not shown) such as a screw. The two fixing plates 120 located at the left and right ends have fixing holes (not shown) in the rear plate 120a to which bolts 93 are fastened.

[0068] The mounting plate 121 is a Z-shaped member when viewed from the side. The mounting plate 121 is formed, for example, by bending a steel plate that is thicker than the metal outer skins 90 and 91. An insertion hole into which the bolt 93 is inserted is provided in the upper part of the mounting plate 121.

[0069] With the upper part of the mounting plate 121 fixed to the rear plate 120a of the fixed plate 120 by the bolts 93, the lower part of the mounting plate 121 is positioned rearward and away from the rear plate 120a of the fixed plate 120. The rear plate 120a of the fixed plate 120 and the lower part of the mounting plate 121 surround an insertion groove 122 that opens downward.

[0070] The sandwich panel 9 further includes gaskets 94 attached to the upper wall portion 901, the lower wall portion 902, and the left and right side wall portions 903 of the metal outer skin 90. The gaskets 94 are not shown in FIG. 6. As shown in FIGS. 7A, 7B, and 8, the gaskets 94 are attached to the front-to-rear center of the upper surface of the upper wall portion 901, the front-to-rear center of the lower surface of the lower wall portion 902, and the rear ends of the left and right side wall portions 903. The gaskets 94 have a hollow semicircular cross section perpendicular to the longitudinal direction. The gaskets 94 are provided in a rectangular frame shape when viewed from the front, surrounding the entire periphery of the sandwich panel 9. The gaskets 94 are made of, for example, synthetic rubber.

[0071] 2-3.Other The skeleton 10 shown in Fig. 1 includes a plurality of horizontal members 14 arranged vertically. Each of the horizontal members 14 is attached to a base 15 that forms the floor and ceiling of the building. Each of the horizontal members 14 may be fixed to a beam, or may be fixed across a plurality of columns.

[0072] Two adjacent cross members 14 are positioned vertically apart by a distance equivalent to the distance between the upper and lower fixing members 11, 12 attached to the sandwich panel 9. The fixing member 11 of the sandwich panel 9 is attached to the upper cross member 14, and the second fixing member 12 of the sandwich panel 9 is attached to the lower cross member 14.

[0073] The cross member 14 constitutes a part of the skeleton 10, and in this embodiment, is an angle member that is L-shaped in a side view. The cross member 14 is made of steel. The cross member 14 has a vertical plate portion 140 and a horizontal plate portion 141 that extends rearward from the lower end of the vertical plate portion 140.

[0074] Of the vertical plate portions 140 of each cross member 14, the portion corresponding to the fixed plate 120 located in the center of the left-right direction of the second fixing member 12 of the sandwich panel 9 has an L-shaped support member 142, which supports the fixed plate 120 from below, fixed to the front surface by welding or the like.

[0075] The joint width adjusting jig 1 is used, for example, together with another jig 16 shown in Fig. 1. The jig 16 can press against the side surface of the lower end of the second panel P2 to slide the second panel P2 toward the first panel P1, thereby adjusting the joint width between the panels P1 and P2. Note that the jig 16 is not limited to the structure shown in Fig. 1, and can be any jig that can move the second panel P2.

[0076] 3. Joint width adjustment method Next, a method for adjusting the joint width between the first panel P1 and the second panel P2 using the joint width adjusting jig 1 described above will be described.

[0077] First, as shown in FIG. 1, the second panel P2 is placed to the side (left) of the first panel P1, whose position is fixed relative to the cross member 14 of the skeleton 10. At this time, the two mounting plates 121 of the second fixing member 12 at the lower end of the second panel P2 are hooked onto the vertical plate portion 140 of the cross member 14 (see FIG. 10). The mounting plates 121 are temporarily fastened to the fixing plates 120 with bolts 93, allowing the second panel P2 to slide along the longitudinal direction of the cross member 14. The second panel P2 is placed so that the gasket 94 on the right side surface of the second panel P2 abuts the gasket 94 on the left side surface of the first panel P1. At this time, the right end of the fire-resistant material on the right side of the second panel P2 fits into the recess 920 on the left side surface of the core material 92 of the first panel P1.

[0078] Next, the gripping portion 7 is grasped and the joint width adjusting jig 1 is placed above the joint of the panels P1, P2. Next, as shown in Fig. 2, the first hooking portion 3 is inserted from above into the mounting hole 112 of the fixing member 11 of the first panel P1, and the second hooking portion 5 is inserted from above into the mounting hole 112 of the fixing member 11 of the second panel P2. At this time, the lower surfaces of the bases 30, 50 of the hooking portions 3, 5 come into contact with the upper surface of the upper plate 110b of the fixing member 11, and the joint width adjusting jig 1 is attached to the panels P1, P2.

[0079] Next, the operating unit 6 is rotated with a tool 8 such as a wrench (see FIG. 5 ) to move the movable unit 4 and the second hooking unit 5 toward the first hooking unit 3, sandwiching the second joint forming portion 172 of the joint forming unit 17 between the panels P1 and P2. More specifically, the second joint forming portion 172 is sandwiched between the flat plate portions (portions extending in the front-to-rear direction) of the opposing side wall portions 903 of the panels P1 and P2. As a result, a joint of a predetermined width and length equal to the length L2 of the second joint forming portion 172 is formed between the flat plate portions of the opposing side wall portions 903 of the panels P1 and P2. Note that the above work can be performed from above the base 15, so it can be done without temporary scaffolding outside the panels P1 and P2.

[0080] As shown in Fig. 1, the jig 16 presses the second panel P2 from the side (left) of the second panel P2, sliding the second panel P2 and setting the joint width between the panels P1 and P2 to a predetermined width. Setting the joint width between the panels P1 and P2 to a predetermined width compresses the gasket 94 located between the panels P1 and P2, thereby improving the watertightness between the panels P1 and P2. In addition, the fire-resistant material 95 is disposed so as to cover the recesses 920 of the panels P1 and P2, thereby improving the fire resistance between the panels P1 and P2.

[0081] By carrying out the construction as described above, the jig 1 can adjust the joint width between the panels P1 and P2 to a predetermined width.

[0082] Next, an example of a method for fixing the second panel P2 to the cross member 14 will be described.

[0083] First, the two mounting plates 111 of the fixing member 11 of the second panel P2 are fixed to the vertical plate portion 140 of the upper cross member 14 by appropriate means such as welding (see FIG. 10).

[0084] Next, the two bolts 93 of the second fixing member 12 of the second panel P2 are fully tightened, and the two mounting plates 121 are pressed against the vertical plate portions 140 of the cross member 14. At this time, the fixing plate 120 located in the center in the left-right direction of the lower end of the second panel P2 is placed on the receiving member 142 of the cross member 14, and the weight of the second panel P2 is supported by the receiving member 142. Note that the fixing plate 120 is not fixed to the receiving member 142 by welding or the like.

[0085] If another sandwich panel 9 is already installed below the second panel P2, the vertical plate portion 140 of the cross member 14 and the mounting plate 111 of the other sandwich panel 9 are sandwiched between the two mounting plates 121 of the second panel P2 and the opposing fixed plate 120.

[0086] By carrying out the above construction, the second panel P2 is fixed to the cross member 14 with a predetermined joint width formed between it and the first panel P1. Once the second panel P2 has been fixed to the two upper and lower cross members 14, the jigs 1 and 16 are removed. At this time, even if the second joint forming portion 172 of the joint forming portion 17 of the joint width adjusting jig 1 is pulled out from between the panels P1 and P2, the joint forming portion 17 remains attached to the jig body 2, preventing the joint forming portion 17 from falling off.

[0087] By fixing a plurality of sandwich panels 9 to cross members 14 using the above-described construction method, it is possible to form a wall structure such as that shown in FIG. 10. Another fire-resistant material is sandwiched between two adjacent sandwich panels 9. This fire-resistant material is, for example, a strip-shaped material made of a fibrous inorganic material such as alkaline earth silicate blanket (biosoluble fiber). This fire-resistant material is a member that does not easily return to its original shape when compressed.

[0088] 4. Variations A description will now be given of modifications of the joint width adjusting jig 1 of the present embodiment and the joint width adjusting method using the same.

[0089] The joint width adjusting jig 1 is not limited to the shape (structure) shown in Figures 3 and 4, and may be provided in other shapes. For example, the jig body 2, the first hooking portion 3, and the second hooking portion 5 are not limited to being rod-shaped. The movable portion 4 is not limited to being cylindrical, as long as it is attached to the jig body 2 and is movable along the longitudinal direction of the jig body 2. The operating portion 6 is not limited to being a nut, as long as it is attached to the jig body 2 and can move the movable portion 4.

[0090] The joint width adjusting jig 1 does not have to have the gripping portion 7 that is provided integrally with the jig body 2, and the jig body 2 itself may be the part that is gripped. In addition, the shape of the gripping portion 7 is not limited to the L-shape shown in Figures 3 and 4, and may be any other shape, such as a U-shape that is continuous in a circular shape with the jig body 2.

[0091] The panels P1 and P2 are not limited to those to which the fixing members 11 are attached, and the mounting holes 112 may be formed in the metal outer skins 90 of the panels P1 and P2 themselves.

[0092] Furthermore, the fixing members 11 attached to the panels P1 and P2 may be dedicated to adjusting the joint width, rather than being used for fixing to the framework 10. Furthermore, the mounting holes 112 of the fixing members 11 may be holes separate from the holes through which the hanging devices 13 are attached and detached.

[0093] The portion on which the first hook portion 3 is hooked may be any end portion of the first panel P1 adjacent to the second panel P2, and is not limited to the edge of the mounting hole 112 in the upper plate 110b, but may be the left or right end surface of the upper plate 110b, the metal outer skins 90, 91 of the first panel P1, or another member fixed to the first panel P1. The same applies to the portion on which the second hook portion 5 is hooked.

[0094] The joint width adjusting jig 1 may be used in a reversed orientation, not limited to that shown in Fig. 2. In this case, the sandwich panel 9 on the left side is the first panel P1, and the sandwich panel 9 on the right side is the second panel P2.

[0095] The fixing member 11 does not necessarily have to have the upper plate 110b that fits along the upper surfaces of the panels P1 and P2. The mounting holes 112 may be formed in the rear plate 110a.

[0096] The joint width adjusting jig 1 is not limited to being positioned above the joints of the panels P1 and P2, but may also be positioned in front of, behind, or below the joints.

[0097] The joint width adjusting jig 1 is not limited to adjustment of the joint between the panels P1 and P2 adjacent in the left-right direction, but may also be used to adjust the joint between the panels P1 and P2 adjacent in the up-down direction.

[0098] The first panel P1 and the second panel P2 may be panels of different shapes and sizes.

[0099] Furthermore, the panels P1 and P2 are not limited to the sandwich panels 9, but may be ALC (autoclaved lightweight concrete) panels, ceramic panels, metal siding materials, wooden panels, or the like.

[0100] Moreover, the panels P1 and P2 may have only the fixing member 11 attached thereto, and the second fixing member 12 not attached thereto.

[0101] Furthermore, the joint forming part 17 is not limited to the above-described structure. The joint forming part 17 may be attached to the jig body 2 so as to be immovable in the longitudinal direction of the jig body 2, or may be attached so as to be immovable.

[0102] The joint forming portion 17 may include only one of the first joint forming portion 171 and the second joint forming portion 172, and may be, for example, L-shaped.

[0103] Furthermore, the joint forming portion 17 is not limited to being made of synthetic resin, but may be made of metal, or may be formed by combining a synthetic resin portion with a metal portion.

[0104] Furthermore, the joint forming portion 17 is not limited to the structure shown in FIG. 3, as long as it can be attached to the jig body 2 and sandwiched between the panels P1 and P2.

[0105] The arm portion 170 and the first joint forming portion 171 and the second joint forming portion 172 may be provided so that their longitudinal directions intersect at an angle other than 90 degrees.

[0106] The lengths L1 and L2 (widths) of the first joint forming portion 171 and the second joint forming portion 172 are not limited to being the same, and may be different from each other.

[0107] Furthermore, the joint forming portion 17 does not have to be composed of one member. For example, the joint forming portion 17 may be composed of a cord-like body such as a wire, one end of which is attached to the jig body 2, and a block-like member of a predetermined width (a width corresponding to the joint between the panels P1 and P2) attached to the other end of the cord-like body.

[0108] 5. Summary As in the embodiment and its modified example described above, the joint width adjusting jig (1) of the first aspect has the following configuration.

[0109] That is, the joint width adjusting jig (1) of the first embodiment is a joint width adjusting jig (1) for adjusting the joint width between a first panel (P1) and a second panel (P2). The joint width adjusting jig (1) includes a jig body (2) that is elongated in one direction, a first hooking portion (3), a movable portion (4), a second hooking portion (5), an operating portion (6), and a joint forming portion (17). The first hooking portion (3) is provided integrally with the jig body (2) and configured to hook onto the end of the first panel (P1) on the side adjacent to the second panel (P2). The movable portion (4) is attached to the jig body (2) and is movable along the longitudinal direction of the jig body (2). The second hooking portion (5) is provided integrally with the movable portion (4) and configured to hook onto the end of the second panel (P2) on the side adjacent to the first panel (P1). The operating part (6) is attached to the jig body (2) and can move the movable part (4). The joint forming part (17) is attached to the jig body (2) and can be sandwiched between the first panel (P1) and the second panel (P2).

[0110] The joint width adjusting jig (1) of the first embodiment having the above-described configuration can be formed with a short length that spans the space between the adjacent ends of the panels (P1, P2), making it easy to handle. Furthermore, in the joint width adjusting jig (1) of the first embodiment, the hooking portions (3, 5) can be hooked onto the adjacent ends of the panels (P1, P2) and the operating portion (6) can be operated from a position close to the joint between the panels (P1, P2), thereby reducing the need for the installer to move between the operating position of the operating portion (6) and the position for checking the joint width. Furthermore, in the joint width adjusting jig (1) of the first embodiment, the joint forming portion (17) attached to the jig body (2) can be sandwiched between the panels (P1, P2) to set the joint width between the panels (P1, P2) to a predetermined width, eliminating the need to measure the joint width with a ruler. This makes it easier to adjust the joint width between the panels (P1, P2) with the joint width adjusting jig (1) of the first embodiment. Also, the same joint width adjusting jig (1) can be used regardless of the dimensions of the panels (P1, P2), making it highly versatile.

[0111] Furthermore, as in the above-described embodiment and its modified example, the second aspect of the joint width adjusting jig (1) additionally has the following configuration in addition to the configuration of the first aspect of the joint width adjusting jig (1).

[0112] That is, in the joint width adjusting jig (1) of the second embodiment, the joint forming portion (17) is attached to the jig body (2) so as to be movable in the longitudinal direction of the jig body (2).

[0113] In the second embodiment of the joint width adjusting jig (1) having the above-described configuration, the position of the joint forming portion (17) in the longitudinal direction of the jig body (2) can be adjusted as appropriate, so that even if there are manufacturing errors in the panels (P1, P2), the joint forming portion (17) can be easily sandwiched between the panels (P1, P2).

[0114] Furthermore, as in the above-described embodiment and its modified example, the joint width adjusting jig (1) of the third aspect additionally has the following configuration in addition to the configuration of the joint width adjusting jig (1) of the first or second aspect.

[0115] That is, in the joint width adjusting jig (1) of the third embodiment, the joint forming portion (17) is attached to the jig body (2) so as to be rotatable around the central axis of the jig body (2).

[0116] In the third embodiment of the joint width adjustment jig (1) having the above-mentioned configuration, the joint forming portion (17) can be rotated around the central axis of the jig body (2), making it easy to insert and remove the joint forming portion (17) between the panels (P1, P2).

[0117] Furthermore, as in the above-described embodiment and its modified example, the joint width adjusting jig (1) of the fourth aspect additionally has the following configuration in addition to the configuration of the joint width adjusting jig (1) of the third aspect.

[0118] That is, in the fourth embodiment of the joint width adjusting jig (1), the joint forming portion (17) has an arm portion (170) having one longitudinal end rotatably attached to the jig body (2), and a first joint forming portion (171) and a second joint forming portion (172) extending in opposite directions from the other longitudinal end of the arm portion (170).

[0119] In the fourth aspect of the joint width adjusting jig (1) having the above-mentioned configuration, the part to be inserted between the panels (P1, P2) can be selected from the first joint forming part (171) and the second joint forming part (172) depending on the construction situation, making it highly versatile.

[0120] Furthermore, as in the above-described embodiment and its modified example, the joint width adjusting jig (1) of the fifth aspect additionally has the following configuration in addition to the configuration of the joint width adjusting jig (1) of any one of the first to fourth aspects.

[0121] That is, in the joint width adjusting jig (1) of the fifth embodiment, the joint forming portion (17) is made of synthetic resin.

[0122] By providing the above configuration, the joint width adjusting jig (1) of the fifth aspect can prevent scratches on the surfaces of the panels (P1, P2) when the joint forming part (17) is inserted and removed between the panels (P1, P2). Furthermore, the joint width adjusting jig (1) of the fifth aspect is easier to handle because it is easier to reduce the weight of the joint width adjusting jig (1) than when the joint forming part (17) is made of metal.

[0123] As in the above-described embodiment and its variants, a sixth aspect of the joint width adjustment method is a method for adjusting the joint width between a first panel (P1) and a second panel (P2) using the joint width adjusting jig (1) of any one of the first to fifth aspects. In the sixth aspect of the joint width adjustment method, the first hooking portion (3) is hooked onto the end of the first panel (P1) adjacent to the second panel (P2), and the second hooking portion (5) is hooked onto the end of the second panel (P2) adjacent to the first panel (P1). Thereafter, in the fifth aspect of the joint width adjustment method, the operating portion (6) is operated to move the movable portion (4) and the second hooking portion (5), sandwiching the joint forming portion (17) between the first panel (P1) and the second panel (P2) and setting the joint width between the first panel (P1) and the second panel (P2) to a predetermined width.

[0124] In the joint width adjustment method of the fifth aspect having the above configuration, the operating unit (6) can be operated at a position close to the joint between the panels (P1, P2), movement of the operating unit (6) between the operating position and the joint width confirmation position can be suppressed, and a joint of a predetermined width can be formed between the panels (P1, P2) simply by clamping the joint forming unit (17). Therefore, the joint width adjustment method of the fifth aspect makes it easier to adjust the joint width between the panels (P1, P2).

[0125] The present disclosure has been described above based on the embodiments shown in the accompanying drawings, but the present disclosure is not limited to the above-described embodiments, and appropriate design changes are possible within the intended scope of the present disclosure.
