Description

Technical Field

[0001] One embodiment of the present invention relates to a jig and method for fixing a panel used as an outer wall of a building to a body edge.

Background Art

[0002] Large-scale buildings such as logistics facilities like warehouses, factories, and commercial buildings are often constructed by building a framework that serves as the building's skeleton and attaching outer walls, louvers, fixtures, windows, etc. to the framework. When a special exterior shape or design is not required for a large-scale building, the building can be constructed in a short construction period by using an outer wall panel (hereinafter simply referred to as a panel) in which a non-combustible heat insulating material such as rock wool is sandwiched between steel plates as the outer wall (see Patent Document 1).

Mode for Carrying Out the Invention

[0008] Hereinafter, each embodiment of the present invention will be described with reference to the drawings and the like. However, the present invention can be implemented in various modes without departing from the gist thereof, and is not to be construed as being limited to the description of the embodiments exemplified below.

[0009] The drawings may schematically represent the width, thickness, shape, etc. of each part compared to the actual aspect for the sake of clearer explanation, but this is merely an example and does not limit the interpretation of the present invention. In this specification and each figure, elements having the same functions as those described with respect to the previously shown figures may be denoted by the same reference numerals, and redundant explanations may be omitted. When representing a part of an element with a reference numeral, a lowercase alphabet is appended to the reference numeral.

[0010] Hereinafter, a jig for fixing a panel to a body edge according to one of the embodiments of the present invention, and a method for fixing the panel to the body edge using this jig will be described. More specifically, a jig and a method for fixing a panel to a body edge fixed to a building by an operation inside the building will be described.

[0011] 1. Body Edge and Panel As shown in Fig. 1(A), the building 10 has a basic framework including a foundation beam 12 connected to a pile or foundation concrete (not shown), and bodies 14 and 16 connected to the foundation beam 12. The external shape of the building 10 is mainly determined by the bodies 14 and 16. A plurality of body edges 18 extending in the vertical direction and / or the horizontal direction are fixed to the bodies 14 and 16. Each panel 20 is lifted by a hoisting machine such as a crane, transported to a predetermined position, and attached to the bodies 14 and 16 using fixtures such as screws and nails (hereinafter, fixtures are generally referred to as screws). In the following description, an example in which the body edges 18 are arranged in the vertical direction will be mainly used for explanation. However, the jig according to one embodiment of the present invention can also fix the panel 20 to the horizontally arranged body edges 18.

[0012] The body edge 18 has a function of supporting the panel 20 and is a linearly extending frame including a metal such as aluminum or iron, an alloy such as stainless steel, wood, or resin. The body edge 18 may be a plate extending in one direction, a hollow tube, or a rod without a cavity. For example, the body edge 18 may be a so-called grooved steel with a lip, or an angle steel pipe having a closed cross-sectional shape. The body edge 18 may also be a grooved steel without a lip (parallel flange grooved steel) or an H-shaped steel. At least a part of the outer surface of the body edge 18 is flat over the entire direction in which the body edge 18 extends, and the panel 20 is arranged and fixed on this flat surface. The length, width, and thickness of the body edge 18 are arbitrary, and for example, it may be configured to satisfy Japanese Industrial Standard (JIS) G 3350.

[0013] The panel 20 includes mineral fibers such as wood, cement, metal, rock wool, calcium silicate, gypsum, resin, etc., and is configured to have a single-layer structure or a laminated structure. For example, mineral fibers such as glass wool and rock wool, fibers derived from natural polymers such as cellulose fibers, heat insulating materials such as foamed plastics containing polyurethane, polystyrene or phenolic resin, calcium silicate, gypsum, etc. are processed into plate shapes, and a structure in which these are sandwiched between a pair of metal plates, resin plates, wooden plates, etc. can be adopted. When using a metal plate, the metal plate can include metals such as aluminum and iron, or alloys such as stainless steel, and its surface may be covered with an alloy film containing aluminum or zinc. The length (length in the longitudinal direction) and width (length perpendicular to the longitudinal direction) of each panel 20 can be arbitrarily determined. The length of the panel 20 is, for example, 1 m or more and 10 m or less, 2 m or more and 6 m or less, 3 m or more and 7 m or less, 5 m or more and 6 m or less, or 3 m or more and 5 m or less. The width of the panel 20 is, for example, 20 cm or more and 200 cm or less, 60 cm or more and 100 cm or less, 30 cm or more and 150 cm or less, or 30 cm or more and 100 cm or less.

[0014] As shown in FIG. 1(B), usually, a pair of rails 20a and 20b extending along the opposing long sides are respectively provided on the panel 20. When fixing two panels 20 vertically to one body edge 18, the rail 20a of the lower panel 20 is sandwiched by the rail 20b of the upper panel 20. Since the panel 20 is configured such that the main surface 20c of the lower panel 20 and one of the rails 20b of the upper panel 20 are substantially in the same plane, the thickness of the panel 20 is reduced at the end portion 20d on the long side where the rail 20a is provided. The screw 24 is driven through the end portion 20d of the lower panel 20 to reach the body edge 18, and the upper panel 20 is arranged such that the rail 20b of the upper panel 20 covers the screw 24.

[0015] As described below, the attachment of the panel 20 is performed as work inside the building 10. That is, as work of the worker arranged on the body edge 18 side with respect to the panel 20, the screw 24 is driven into the panel 20 and the body edge 18, and the panel 20 is fixed to the body edge 18. In the following description, for convenience, the direction in which the screw 24 is driven is defined as the y direction, and the vertical direction is defined as the z direction. The direction perpendicular to the y direction and the z direction is the x direction in which the panel 20 extends. Further, when the electric driver 22 operates to rotate the screw 24, the rotation axis thereof is referred to as the first axis. Therefore, the rotation axis of the rotating sleeve of the electric driver 22 and the axis of the screw 24 are also coaxial with the first axis. The first axis is parallel to the y direction.

[0016] 2. Fixture 2-1. Overall Structure FIG. 2 shows a schematic perspective view of a fixture 100 for fixing a panel 20 to a body edge 18, which is one of the embodiments of the present invention. As shown in FIG. 2, the fixture 100 mainly includes a driver unit 110 and a fixing unit 150. The driver unit 110 and the fixing unit 150 are connected to each other, and by their collaborative function, the fixing of the panel 20 to the body edge 18 can be carried out as work inside the building 10.

[0017] 2-2. Driver Unit A schematic side view and a top view of the driver unit 110 are shown in FIGS. 3(A) and 3(B), respectively. In these figures, for the sake of clarity, the configurations other than the driver unit 110 are shown by dotted lines, and further, the panel 20 is shown by a chain line. The driver unit 110 supports an electric driver 22 that rotates a screw when fixing the panel 20 and the body edge 18 using the screw 24, and has a function of sliding the electric driver 22 toward the panel 20 side. As the driver unit 110, any configuration can be adopted as long as these functions are exhibited. In the example shown in FIG. 2, the driver unit 110 includes a deck 124, a back panel 126, and a front panel 122 as a support mechanism for supporting the electric driver 22, and includes an air cylinder 114 having a slide shaft 116 as a slide mechanism for reversibly sliding the electric driver 22 in the y direction. The slide shaft 116 is connected to the support mechanism. Further, as a mechanism for disposing the jig 100 on the panel 20, the driver unit 110 may include a fitting portion 132 (see FIGS. 3(A) and 3(B)).

[0018] The air cylinder 114 can be fixed, for example, on a platform 112 having a main surface in the xy plane. The length of the platform 112 in the y direction is such that when the slide shaft 116 is at the position farthest from the fitting portion 132, the screw 24 can be attached to the electric driver 22, and when it is at the position closest to the fitting portion 132, the head of the screwed-in screw 24 contacts the end 20d of the panel 20, and is appropriately adjusted. The air cylinder 114 has an inlet 118 and an outlet 120, and the inlet 118 and the outlet 120 are connected to the switch 144 by an air tube (not shown). Compressed air is introduced into the air cylinder 114 from an air compressor (not shown) via the switch 144 and the air tube to apply torque to the slide shaft 116 in the y direction. One or more grooves 114a for accommodating a part of the deck 124 of the support mechanism may be provided on the upper surface of the air cylinder 114 (FIGS. 2 and 3(B)). By sliding the support mechanism with a part of the deck 124 of the support mechanism accommodated in the groove 114a, the support mechanism can be more precisely slid in the y direction. In the examples shown in FIGS. 3(A) and 3(B), the switch 144 is provided on the arm 154, but the position of the switch 144 may be set arbitrarily. For example, an air cylinder 114 equipped with a switch may be used, or a pedal-type switch that is not fixed to the jig 100 may be arranged on the floor surface.

[0019] In the support mechanism provided on the slide mechanism, the front panel 122 and the back panel 126 are fixed to the deck 124. An opening 122a for accommodating a part of the electric driver 22 is provided in the front panel 122 when the electric driver 22 is supported by the support mechanism (Figure 2). Further, the front panel 122 is connected to the slide shaft 116, and the support mechanism slides reversibly in the y direction as the slide shaft 116 moves. The back panel 126 faces the front panel 122 in the y direction and supports the back of the electric driver 22. By sandwiching the electric driver 22 between the back panel 126 and the front panel 122 with a part of the electric driver 22 accommodated in the opening 122a, the electric driver 22 can be supported in an inverted state (that is, a state where the trigger of the electric driver 22 is located above the sleeve). As an optional configuration, a side rest 128 that abuts against the side surface of the electric driver 22 may be provided on the back panel 126. By providing the side rest 128, the electric driver 22 can be more stably supported by the support mechanism.

[0020] In the example shown in FIGS. 2 to 3(B), the air cylinder 114 has two slide shafts 116, but an air cylinder 114 having a single slide shaft 116 may be used. Thereby, the weight of the air cylinder 114 can be reduced. Further, in the case of a single slide shaft 116, flexibility is imparted in the direction in which the support mechanism slides, and the slide direction of the support mechanism can be finely adjusted not only in the y direction but also in a direction deviated vertically, horizontally, or diagonally from the y direction (for example, a direction deviated by ±10°). Therefore, even if a deviation occurs in the driving direction of the screw 24, the screw 24 does not come off from the bit of the electric driver (the part that abuts against the head of the screw 24 and meshes with the screw hole), and the screw 24 can be driven while flexibly coping with this deviation.

[0021] Here, in the driver unit 110 shown in FIGS. 2 to 3(B), the air cylinder 114 is fixed to the platform 112, and the support mechanism slides as the slide shaft 116 slides. Therefore, even if the slide shaft 116 is slid, the position of the air cylinder 114 with respect to the panel 20, the body edge 18, and the fixing unit 150 does not change. However, the driver unit 110 is not limited to such a structure, and the slide shaft 116 may be used instead of the platform 112, and the air cylinder 114 and the support mechanism fixed thereto may be slid on the slide shaft 116. For example, as shown in FIGS. 4(A) and 4(B), by fixing the slide shaft 116 directly to the first disc 140 (described later) on the fixing unit 150 side or via the hanger 130 (described later), the position of the slide shaft 116 with respect to the panel 20, the body edge 18, and the fixing unit 150 is fixed. Thereby, the air cylinder 114 and the support mechanism can be slid on the slide shaft 116 while the slide shaft 116 is fixed. In this case, since the platform 112 becomes unnecessary, further weight reduction can be achieved.

[0022] A schematic perspective view and a side view centered on the fitting portion 132 are shown in FIGS. 5 and 6(A), respectively. The fitting portion 132 is connected to the slide mechanism and fits with one side of the panel 20. The connection method between the fitting portion 132 and the slide mechanism is also arbitrary. For example, a hanger 130 extending in the normal direction of the platform 112 can be fixed to the platform 112 (see FIGS. 1, 3(A), and 3(B)), and the fitting portion 132 can be provided at the end of the hanger 130. The fitting portion 132 can be composed of a hook 136, a cap plate 134, a spacer 138, and the like. The hook 136 and the cap plate 134 may be integrated, or may be fixed to each other as independent parts by bolts or welding. On the other hand, the spacer 138 is separated from the hook 136 and the cap plate 134 and is fixed directly or indirectly to the hanger 130. In the example shown in FIGS. 5 and 6(A), the fitting portion 132 includes a pair of hooks 136, a pair of cap plates 134, and a pair of spacers 138. However, there is no restriction on the number of the hook 136, the cap plate 134, and the spacer 138, and each may be one or three or more. For example, the fitting portion 132 may be configured such that one hook 136 is clamped by a pair of cap plates 134. Alternatively, the fitting portion 132 may be configured such that one cap plate 134 is clamped by a pair of hooks 136.

[0023] The hook 136 is configured to mesh with a pair of rails 20a provided on one side of the panel 20. More specifically, as shown in FIG. 6(A), a part 136a is inserted between the pair of rails 20a, and this part 136a and another part 136b can be configured to sandwich the rail 20a farther from the main surface 20c (FIG. 6(A)). The hook 136 is preferably configured such that the side surface on the side far from the slide mechanism and the support mechanism is located on the same plane as the back surface 20e of the panel 20. Thereby, with the body edge 18 in contact with the panel 20, the jig 100 can be suspended and fixed from the panel 20 via the hanger 130.

[0024] The spacer 138 abuts against the main surface 20c in a state where the hook 136 is fitted to the panel 20, and its length (the length in the y direction) is set such that the rotation axis of the sleeve of the electric driver 22, that is, the first axis, faces the y direction. For this reason, by simply suspending the jig 100 from the panel 20 using the fitting portion 132, the electric driver 22 can be accurately positioned. In a state where the jig 100 is suspended, the end portion 20d is disposed between the hook 136 and the spacer 138.

[0025] By providing the fitting portion 132 in this way, the jig 100 can be stably fixed to the panel 20, and the positioning for fixing the panel 20 and the body edge 18 using the screw 24 can be easily performed. However, it is not always necessary to provide the fitting portion 132. For example, as shown in FIG. 6(B), a cap plate 135 having an L-shaped end surface parallel to the yz plane that overlaps the pair of rails 20a and covers the side surface of the rail 20a on the body edge 18 side on the body edge 18 side may be used as the support portion 133 for suspending the driver unit 110. In this case, as shown in FIG. 6(C), the cap plate 135 may be a flat plate having the z direction as the normal line.

[0026] The driver unit 110 further includes a first disk 140 as a part for connecting to the fixing unit 150 (see FIG. 2). The first disk 140 can be fixed to, for example, the hanger 130. The first axis A is provided on the first disk 140. 1In addition, an opening 140a through which a part of the screw 24 or the electric driver 22 can pass is formed. There is no restriction on the shape of the opening 140a as long as the electric driver 22 and the first disk 140 do not interfere when the screw 24 is driven and the head of the screw 24 abuts against the panel 20. Preferably, the shape of the opening 140a (the shape in the xz plane) is a circle, and its center coincides with the first axis. Although not shown, the outer periphery of the part for connecting to the fixing unit 150 may not be circular but an arc having a notch corresponding to the opening 140a. For example, a part whose outer periphery in contact with the second disk 152 to be described later is a semi-circle or an arc and has a semi-circular or fan-shaped notch through which a part of the screw 24 or the electric driver 22 can pass may be used instead of the first disk 140. Further, the first disk 140 may be a toroidal body (ring body, annular body) having a so-called donut shape or a tubular shape.

[0027] 2-3. Fixing Unit A schematic perspective view centered on the fixing unit 150 is shown in FIG. 7(A), and a schematic rear view seen from the y direction is shown in FIG. 7(B). In FIG. 7(A), parts other than the fixing unit 150 are shown by dotted lines, and the panel 20 is shown by a chain line. The fixing unit 150 has a so-called vise structure, is connected to the driver unit 110, and is a unit having a function of fixing the body edge 18 and the panel 20 to each other. There is no restriction on the configuration of the fixing unit 150 as long as these functions can be realized. In the example shown in FIGS. 2, 7(A), and 7(B), the fixing unit 150 includes a second disk 152, a slide jaw 156, and an arm 154 as basic components.

[0028] The second disk 152 surrounds the first disk 140 and rotates around the first axis A around the first disk 140. 1It is configured to rotate about (refer to the arrow in Fig. 7(B)). That is, the second disk 152 is provided with a circular opening surrounding the first disk 140, and the first disk 140 is disposed within this opening. Although not shown, one or more grooves overlapping each other on the yz plane may be provided on the inner wall of the second disk 152 and the outer side surface of the disk of the first disk 140, and a bearing may be provided between these grooves. By surrounding the first disk 140 with the second disk 152, the fixing unit 150 is connected to the driver unit 110. The second disk 152 may be attached to the first disk 140 so as to be detachable, or may be attached substantially permanently. Similar to the first disk 140, the second disk 152 may also be a toroidal body (ring body, annular body) or may be tubular.

[0029] The slide jaw 156 faces the second disk 152 and the first disk 140 and is configured to slide in the y direction. A configuration for sliding in the y direction can also be appropriately designed. For example, as shown in Figs. 2, 7(A), and 7(B), a spindle 158 and a handle 160 for rotating the spindle 158 can be provided on the slide jaw 156. By rotating the handle 160, the spindle 158 slides reversibly in the y direction while rotating, and as a result, the slide jaw 156 slides reversibly in the y direction.

[0030] The arm 154 connects the second disk 152 and the slide jaw 156 to each other. At least a part of the arm 154 extends in a direction parallel to the y direction. Also, the arm 154 is configured such that the direction in which the slide jaw 156 slides coincides with the first axis A 1 Arrange the body edge 18 and the panel 20 simultaneously between the second disk 152 and the slide jaw 156, and direct the slide jaw 156 toward the driver unit 110 along the first axis A 1By sliding upward, the body edge 18 and the panel 20 can be fixed, and the driver unit 110 can be stably fixed on the panel 20. As described above, the first disc 140 is fixed to the hanger 130 using welding or bolts 142, etc., while the second disc 152 rotates around the first disc 140. Therefore, the arm 154 is connected to the driver unit 110 via the second disc 152, and the fixing unit 150 and its arm 154 also rotate about the first axis A 1 as the center. For this reason, the jig 100 can be arranged and fixed using the fixing unit 150 without depending on the thickness of the body edge 18 (length in the x direction). Furthermore, the arrangement position of the arm 154 with respect to the body edge 18 can be arbitrarily selected. That is, the arm 154 can be arranged on the +x side with respect to the body edge 18, or it can also be arranged on the -x side. For this reason, the jig 100 can be arranged flexibly according to the situation around the body edge 18. Although not shown, the fixing unit may have a plurality of slide jaws 156. In this case, the plurality of slide jaws 156 are configured to slide on the first axis A 1 or an axis parallel thereto.

[0031] 2-4. Screw Holder The jig 100 may further have, as an arbitrary configuration, a screw holder for temporarily fixing the screw 24. The screw holder is configured to allow movement in the y direction by supporting the screw 24 before it is struck on the panel 20 and releasing the screw 24 when the screw 24 is struck. Thereby, the screw 24 can be arranged at a predetermined position before the screw 24 is struck on the panel 20. Furthermore, when the screw 24 is struck on the panel 20 and a part thereof enters the panel 20, the screw 24 becomes stable, but at this time, the screw 24 is released and it can be slid in the direction of the panel 20 according to the operation of the electric driver 22.

[0032] There are no restrictions on the configuration of the screw holder. However, for example, as shown in FIGS. 2 and 8(A), a pair of sliding plates 170 may be provided as the screw holder. The sliding plate 170 is attached directly or indirectly to, for example, the hanger 130. The sliding plate 170 may be attached to the first disc 140. The sliding plate 170 is attached to the hanger 130 or the first disc 140 etc. using an anchor bolt 172 so as to slide reversibly in a direction perpendicular to the first axis A 1 (for example, the x direction). The anchor bolt 172 penetrates the sliding plate 170, and an opening 170a extending in the direction in which the sliding plate 170 slides is provided, and the sliding plate 170 can be moved in the x direction using this opening 170a.

[0033] Each sliding plate 170 is provided with notches 170b that face each other in the direction in which the sliding plate 170 slides (FIGS. 8(A) and 8(B)). The notches 170b are formed to accommodate the screws 24 when the pair of sliding plates 170 sandwich the screws 24. Therefore, the shape of the notches 170b (the shape viewed from the y direction) is preferably the same as a part of the end face shape of the screws 24. As shown in FIG. 8(B), the side walls of the notches 170b preferably have an inclination such that the shape on the driver unit 110 side is larger than the shape on the fixed unit 150 side. By providing such an inclination, when the head abuts against the sliding plate 170 after the driving of the screw 24 starts, the sliding plate 170 automatically gradually opens and can release the screw 24. Therefore, when the jig 100 is disposed on the panel 20, the sliding plate 170 is preferably arranged such that the distance between the notch 170b and the panel 20 (that is, the distance in the y direction from the notch 170b to the end on the fixed unit 150 side of the spacer 138) is shorter than the length excluding the head of the screw 24. By adopting such sizing, it is possible to prevent the screw 24 from being released before the screw 24 abuts against the panel 20, and the screw 24 can be released after a part of the screw 24 is driven into the panel 20 and stabilized.

[0034] Alternatively, as shown in FIGS. 9 to 10(B), the screw holder may include a pair of rotating claws 180 configured to reversibly take a closed state in which the screw 24 can be supported by rotating in opposite directions to each other and an open state in which the screw 24 is released. More specifically, the screw holder may be configured to include, in addition to the pair of rotating claws 180, a third disk 182, a lever 184, an operation rod 190, and the like.

[0035] The third disk 182 is surrounded by the first disk 140 and the first axis A 1It is configured to rotate relative to the first disk 140 about the center. The third disk 182 is provided with an opening for accommodating a pair of rotating claws 180, and notches 182a that engage with the pair of rotating claws 180 are respectively provided on the inner wall of the opening. Similar to the first disk 140 and the second disk 152, the third disk 182 may also be a torus body (ring body, annular body) or a tubular shape.

[0036] On the other hand, the pair of rotating claws 180 is surrounded by the third disk 182 and attached to the hanger 130. At this time, the pair of rotating claws 180 are respectively attached to the hanger 130 so as to rotate about the second axis A 2 and the third axis A 3 (FIG. 9). The second axis A 2 and the third axis A 3 are parallel to the first axis A 1 and penetrate through the opening of the third disk 182. Further, protrusions 180a that engage with the notches 182a are provided on the pair of rotating claws 180 (FIG. 10(A)). By accommodating the protrusions 180a in the notches 182a, they engage with each other, and as a result, the pair of rotating claws 180 engages with the third disk 182. Further, notches 180b are formed at the ends of the pair of rotating claws 180 on the side opposite to the protrusions 180a respectively (see FIG. 10(B)). The two notches 180b respectively accommodate a part of the screw 24 and are formed so as to sandwich the screw 24 from above and below. For this reason, it is preferable that the shape of the notch 180b (the shape seen from the y direction) is the same as a part of the end face shape of the screw 24. Although not shown, similar to the notch 170b of the sliding plate 170, the side wall of the notch 180b may also have an inclination.

[0037] The lever 184 is fixed to the third disk 182. For example, one end of the lever 184 is fixed to the outer peripheral surface of the third disk 182. A pair of rollers 186 that overlap in the z direction are provided at the other end of the lever 184, and a bent operation rod 190 is arranged so as to be sandwiched between the pair of rollers 186. As shown in FIG. 9, the operation rod 190 is fixed to a support mechanism, for example, the front panel 122, and extends in the y direction. However, the operation rod 190 has first and second vector components that extend in the y direction and are parallel to each other. For example, as shown in FIG. 9, the operation rod 190 includes a portion having a first vector component on the side of the panel 20, that is, on the side opposite to the driver unit 110, and a portion having a second vector component on the driver unit 110. When the driver unit 110 is in the state farthest from the panel 20, the portion having the first component is sandwiched between the pair of rollers 186, and when the driver unit 110 moves toward the panel 20, the portion between the portion having the first vector component and the portion having the second vector component advances between the pair of rollers 186, and the operation rod 190 is configured such that the portion having the second vector component is sandwiched between the pair of rollers 186.

[0038] In the screw holder having such a configuration, as shown in FIGS. 10(A) and 10(B), when the third disk 182 rotates in one direction (for example, clockwise) about the first axis A 1 (curved arrow c), the notch 182a also rotates about the first axis A 1 At the same time, the protrusion 180a that meshes with the notch 182a moves along with the rotation of the notch 182a in order to maintain the state of being accommodated in the notch 182a. However, as described above, the pair of rotating claws 180 are fixed to the hanger 130 so as to rotate about the second axis A 2 and the third axis A 3 respectively. For this reason, the pair of rotating claws 180 rotate in opposite directions (curved arrow d) about the second axis A 2 and the third axis A 3 respectively, and the notches 180b are separated from each other and opened. Conversely, when the third disk 182 rotates about the first axis A 1When it rotates in the reverse direction (e.g., counterclockwise) around the center, the notches 180b approach each other and take a closed state. In the closed state, the protrusion 180a of the rotating claw (the left rotating claw 180-1 in Fig. 10(A)) located below the screw 24 is caught by the notch 182a, and the shapes of the protrusion 180a and the notch 182a are adjusted so that it does not rotate clockwise. As a result, in the closed state, the screw 24 can be supported within the notches 180b of the pair of rotating claws 180, and the screw 24 can be released in the open state.

[0039] On the other hand, the operation rod 190 may be configured such that the first vector component is above the second vector component (a position closer to the screw 24 in the z direction) (see Fig. 9). Thereby, a closed state is obtained when the portion having the first vector component is sandwiched by the rollers 186. When the operation rod 190 slides in the y direction toward the panel 20 (linear arrow a in Fig. 9) and the portion having the second vector component is sandwiched by the rollers 186, the lever 184 is pushed down (linear arrow b). As a result, the third disk 182 rotates clockwise (curved arrow c), and the rotating claw 180 rotates (curved arrow d).

[0040] Conversely, when transitioning from the closed state to the open state by rotating the third disk 182 counterclockwise, the operation rod 190 may be configured such that the first vector component is below the second vector component (a position farther from the screw 24 in the z direction). Also, the lengths and intervals of the portions of the operation rod 190 having the first vector component and the second vector component are appropriately adjusted so that a transition from the closed state to the open state starts after a part of the screw 24 is driven into the panel 20 and its direction becomes stable. In this way, the lever 184, the pair of rollers 186, and the operation rod 190 act as a rotation mechanism for rotating the third disk 182.

[0041] Alternatively, the screw holder may be configured such that the rotating claws 180 open and close in a scissor-like manner. For example, as shown in FIGS. 11(A) and 11(B), it rotates about an axis extending in the y direction (see the curved arrow in FIG. 11(A)), and the screw holder may be configured with a pair of rotating claws 200-1 and 200-2 that sandwich the screw 24, and a pin 204 that presses the pair of rotating claws 200-1 and 200-2. Similar to the rotating claws 180, the rotating claws 200 are also provided with notches for sandwiching the screw 24. The pin 204 is partially housed in a spring pedestal 202 provided with an elastic member such as a spring, and is arranged to close the pair of rotating claws 200-1 and 200-2 by the restoring force of the elastic member. Therefore, by housing the screw 24 in the notch, the screw 24 can be fixed between the rotating claws 200 in a state facing the y direction. The spring pedestal 202 and the rotating claws 200 may be fixed to, for example, the hanger 130, and may be fixed to a base plate 208 provided on the driver unit 110 side with respect to the hanger 130. As an optional configuration, a lever 206 for manually opening and closing the rotating claws 200 may be provided on each of the rotating claws 200.

[0042] A blade 210 is provided on the front panel 122 of the driver unit 110 as a mechanism for opening the rotating claws 200. The shape and position of the blade 210 are adjusted so that the front panel 122 slides in the y direction and is inserted between the rotating claws 200. In the example shown in FIG. 11(A) etc., the mechanism for opening the rotating claws 200 is a plate-shaped blade 210, but the mechanism may be needle-shaped or rod-shaped.

[0043] While clamping the screw 24 with the rotating claws 200 and moving the slide shaft 116 in the y direction, the electric driver 22 and the blade 210 slide in the y direction (see the arrow in Fig. 11(B)). The length of the blade 210 in the y direction is adjusted so that it does not contact the rotating claws 200 when the bit of the electric driver 22 abuts against the head of the screw 24 (see Fig. 12(A)). By further moving the electric driver 22 in the y direction while rotating the bit in this state, driving of the screw 24 is started. When a part of the screw 24 is driven into the panel 20, the screw 24 is stabilized and its stretching direction does not easily change (Fig. 12(B)). Here, the length of the blade 210 is adjusted so that when the screw 24 is stabilized, the blade 210 enters between the rotating claws 200 and the rotation of the rotating claws 200 is started. When the rotation of the rotating claws 200 starts, as shown in Fig. 13(A), the rotating claws 200 are separated from the screw 24. However, since the screw 24 is stabilized, problems such as the screw 24 falling or tilting do not occur.

[0044] When the electric driver 22 is further slid in the y direction while further rotating the bit, the head of the screw 24 overlaps the rotating claws 200 in the x direction (Fig. 13(B)). However, since the blade 210 enters between the rotating claws 200 and further rotates the rotating claws 200, a sufficient distance can be ensured between the rotating claws 200, and interference between the head of the screw 24 and the rotating claws 200 can be prevented. After the screw 24 is driven, when the electric driver 22 and the front panel 122 are slid in the reverse direction, the blade 210 is separated from the rotating claws 200. At this time, since the restoring force of the elastic body disposed on the spring pedestal 202 acts on the pin 204, the rotating claws 200 close and the initial state is reproduced.

[0045] 3. Method for fixing to the body edge of the panel Hereinafter, a method for fixing the panel 20 to the body edge 18 installed in the building 10 using the jig 100 described above will be described.

[0046] 3-1. Attachment of the jig First, convey the panel 20 to a predetermined position (Fig. 1(A)). The conveyance may be performed using a hoisting machine such as a crane. When other panels 20 are already installed and a new panel 20 is to be placed on that panel 20, the new panel 20 may be installed so that the rail 20a of the lower panel 20 is clamped by the rail 20b of the new panel 20 (see Fig. 1(B)).

[0047] Thereafter, fix the jig 100 to the body edge 18 using the fixing unit 150. The jig 100 may be fixed by placing the fitting portion 132 or the support portion 133 on the panel 20. When the driver unit 110 has the fitting portion 132, place the fitting portion 132 on the panel 20 so that the hook 136 meshes with the rail 20a and the cap plate 134 contacts the rail 20a (see Fig. 5). Thereafter, the slide jaw 156 may be slid in the y direction toward the driver unit 110 with the body edge 18 and the panel 20 sandwiched therebetween (see Fig. 7(A)). When the driver unit 110 has the support portion 133, the cap plate 135 may be placed on the pair of rails 20a. By placing the fitting portion 132 or the support portion 133 on the panel 20, the jig 100 can be easily placed at a predetermined position on the panel 20, so that the fixing of the jig 100 can be carried out as an operation inside the building 10.

[0048] Thereafter, place the electric driver 22 on the deck 124 (see Fig. 3(A)). Thereby, the electric driver 22 is supported by the support mechanism. On the other hand, the screw 24 is attached to the screw holder. For example, the screw 24 may be clamped by a pair of sliding plates 170 or a pair of rotating claws 180. In addition, a recess for facilitating the insertion of the screw 24 may be formed in advance in the panel 20 (for example, the end portion 20d) at a position where the tip of the screw 24 contacts the panel 20.

[0049] Note that the panel 20 may be conveyed to a predetermined position after a part of the screw 24 is driven into the panel 20. In this case, a jig 100 not provided with a screw holder may be used.

[0050] 3-2. Driving in the screws Subsequently, start the air compressor and operate the switch 144 from the building 10 side to activate the air cylinder 114. As described above, the operation of the air cylinder 114 causes the slide shaft 116 to slide in the y direction, and the support mechanism connected to the slide shaft 116 slides in the y direction (see the arrow in Fig. 3(A)). After the bit attached to the sleeve of the electric driver 22 abuts against the head of the screw 24, operate the trigger of the electric driver 22 to rotate the bit, and use the air cylinder 114 to apply a torque in the y direction to the support mechanism. At this time, if necessary, the sliding plate 170 of the screw holder may be manually opened to release the screw 24. When using the screw holder illustrated in Figs. 9 to 10(B), the operation rod 190 rotates the third disk 182, whereby the rotating claws 180 open and the screw 24 is automatically released. When the screw 24 penetrates the panel 20 and reaches the body edge 18 and the head of the screw 24 contacts the end 20d, the driving-in is completed (see Fig. 6(A)). If the direction of the screw 24 is deviated from the y direction, the driver unit 110 may be manually moved appropriately to finely adjust the sliding direction.

[0051] When the driving-in is completed, stop the air cylinder 114. Then, for example, put the air cylinder 114 in the neutral state and move the driver unit 110 in the reverse direction. Alternatively, torque may be supplied to the slide shaft 116 so as to move away from the panel 20. Through the above process, the panel 20 can be fixed to the body edge 18.

[0052] As described above, by using the jig 100 according to the embodiment of the present invention, all the fixing operations of the panel 20 to the body edge 18 can be performed on the body edge 18 side, that is, as operations inside the building 10. Therefore, conventionally, in order to fix the panel 20, it was necessary to fix a scaffold around the building 10 and arrange workers outside the building 10 to perform the work. However, by applying the method using the jig 100, the assembly and removal of the scaffold are unnecessary, and a significant reduction in the construction period and implementation cost is possible. In addition, the influence of the weather can also be reduced. Furthermore, since the worker can perform the work inside the building 10, the worker is liberated from the unstable work on the scaffold, and the work can be performed in a safer environment.

[0053] Each of the embodiments described above as embodiments of the present invention can be implemented in appropriate combination as long as they do not contradict each other. Based on each embodiment, those in which those skilled in the art appropriately add, delete, or change the design of the components are also included in the scope of the present invention as long as they have the gist of the present invention.

[0054] Other operational effects different from those brought about by the above-described embodiments are also understood to be brought about by the present invention as a matter of course, as long as they are obvious from the description of this specification or can be easily predicted by those skilled in the art.
