Description

[Technical Field]

[0001] The present invention relates to a fastening jig used when fastening two different members together using a fastener such as a screw. [Background technology]

[0002] When roofing a roof by placing adjacent building panels, a tool such as an electric screwdriver is used to screw the building panels to the sheathing boards. This involves driving the electric screwdriver and pressing it toward the building panels to tighten the screws. Therefore, if the direction in which the electric screwdriver is pressed crosses the vertical direction of the seat, the screws are tightened in a tilted state. This not only results in the building panels not being securely screwed to the sheathing boards, but can also easily cause damage to the sheathing boards and the rafters supporting the sheathing boards. Therefore, before screwing the building panels to the sheathing boards, pilot holes are drilled using an electric drill held on a drill stand (see, for example, Patent Document 1 and Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-082584 [Patent Document 2] Japanese Patent Application Laid-Open No. 2004-122307 Summary of the Invention [Problem to be solved by the invention]

[0004] However, although the work of fastening screws while drilling pilot holes has the advantage of preventing the screw from leaning over, it increases the number of work steps, resulting in a problem of poor work efficiency in roofing work. Therefore, there is a strong demand for means and methods that can prevent the screw from leaning over without drilling pilot holes using an electric drill.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fastening jig that can prevent screws from falling over when screwing a building panel to a sheathing board using a tool such as an electric screwdriver, without having to drill pilot holes using an electric drill. [Means for solving the problem]

[0006] A fastening jig according to one aspect is a fastening jig used when fastening one member to another member using a fastener, and comprises: a pressing portion that is pressed against the outer surface of the one member when fastening the other member to the other member; a gripping portion that is held by an operator when pressing the pressing portion against the outer surface of the one member; and a guide portion that extends in a direction that intersects the outer surface of the one member and has an internal space with both ends in the extension direction that are open, and that guides a fastener inserted into the internal space from one end in the extension direction toward the one member, the guide portion extending along the extension direction of the guide portion from one end to the other end in the extension direction of the guide portion, and having a gap that allows the fastener inserted into the internal space to retreat from the internal space of the guide portion to the outside when the pressing portion is moved in a direction that intersects the extension direction of the guide portion.

[0007] Furthermore, it is preferable that the guide portion is fixed to the pressing portion so that when the pressing portion is pressed against the outer surface of one of the members, the extending direction of the guide portion is perpendicular to the outer surface of the one of the members.

[0008] It is also preferable that the guide portion is fixed to a protruding piece provided on the pressing portion.

[0009] Furthermore, the guide portion is preferably a member having a cross section perpendicular to the extending direction of the guide portion that is arc-shaped, rectangular, or U-shaped.

[0010] Preferably, the fastener is a screw, and the width of the gap is set larger than the outer diameter of the screw. [Effects of the Invention]

[0011] According to the present disclosure, when screwing a building panel to a sheathing board using a tool such as an electric screwdriver, it is possible to prevent the screw from falling over without having to drill a pilot hole using an electric drill. [Brief explanation of the drawings]

[0013] The fastening jig shown in this embodiment will be described with reference to the drawings. In this embodiment, the fastening jig is used, for example, to screw a building panel to a sheathing board, but its use is not limited to screwing a building panel to a sheathing board.

[0014] FIG. 1 is a schematic perspective view showing an example of a fastening jig shown in this embodiment. FIG. 2 is a six-view diagram of the fastening jig shown in FIG. 1. In describing the fastening jig 10 of this embodiment, in FIG. 1, the side on which the guide portion 30 of the fastening jig 10 is provided is referred to as the front, and the side on which the gripping portion 40 is provided is referred to as the rear. Furthermore, the left end side in FIG. 1 in the extension direction of the gripping tube 41 of the fastening jig 10 is referred to as the left, and the right end side in FIG. 1 in this extension direction is referred to as the right. Furthermore, the upper end side in FIG. 1 in the extension direction of the guide portion 30 is referred to as the top, and the lower end side in FIG. 1 in this extension direction is referred to as the bottom.

[0015] As shown in FIGS. 1 and 2, the fastening jig 10 includes a pressing portion 20, a guide portion 30, and a gripping portion 40. The pressing portion 20 includes a rectangular metal plate 21 and an anti-slip member 22 fixed to the bottom surface of the metal plate 21. The metal plate 21 is a rectangular member with its longitudinal direction extending in the left-right direction and its lateral direction extending in the front-rear direction. When the fastening jig 10 is in use, the pressing portion 20 is pressed against, for example, each of the outer skin materials 51, 51 (see FIG. 5) of two adjacent building panels 50, 50 in the girder direction. When the pressing portion 20 is pressed against each of the outer skin materials 51, 51 of the two adjacent building panels 50, 50, the extending direction of the guide portion 30 is perpendicular to the seat surface (in this embodiment, the outer surface 61 a of the tongue piece 61 of the clip 60).

[0016] The anti-slip member 22 is a member that is fixed to the bottom surface of the metal plate 21 using an adhesive or the like. The anti-slip member 22 is a sheet-like member that uses an elastic body such as rubber. The anti-slip member 22 prevents the pressing portion 20 from shifting position relative to each of the exterior materials 51, 51 of the building material panels 50, 50 when the pressing portion 20 is pressed against each of the exterior materials 51, 51 of two adjacent building material panels 50, 50.

[0017] A protruding piece 23 protruding forward from the metal plate 21 is provided at the center of the front end of the metal plate 21. The lower end of the guide portion 30 is fixed to the upper surface of the protruding piece 23 by, for example, welding. The protruding piece 23 has a notch portion 24 cut out from the tip of the protruding piece 23 toward the pressing portion 20. The notch portion 24 has a circular portion 24a and a linear portion 24b extending from the tip of the protruding piece 23 toward the circular portion 24a. The protruding piece 23 may be integral with the metal plate 21 or may be separate from the metal plate 21. If the protruding piece 23 is separate from the metal plate 21, the amount of protrusion of the protruding piece 23 from the front end of the metal plate 21 can be changed.

[0018] The guide portion 30 is a cylindrical member with both ends in the extension direction of the guide portion 30 open. One end of the guide portion 30 in the extension direction of the guide portion 30 is fixed to the upper surface 23a of the protruding piece 23. When the guide portion 30 is fixed to the upper surface 23a of the protruding piece 23, the extension direction of the guide portion 30 is perpendicular to the upper surface 23a of the protruding piece 23. Furthermore, when the guide portion 30 is fixed to the upper surface 23a of the protruding piece 23, the internal space 30a of the guide portion 30 and the circular portion 24a of the cutout portion 24 are communicated with each other. Furthermore, the slit 31 of the guide portion 30 and the linear portion 24b of the cutout portion 24 are communicated with each other.

[0019] The guide part 30 has a long screw 70 inserted into an internal space 30a of the guide part 30 from the upper end of the guide part 30. The guide part 30 suppresses the angle at which the long screw 70 inserted into the internal space 30a falls when the screw is fastened, and also regulates the tightening direction of the long screw 70. The length of the guide part 30 in the extension direction may be set appropriately based on the length of the long screw 70 to be used, etc.

[0020] A slit 31 extending along the extension direction of the guide portion 30 is provided on the outer peripheral surface of the guide portion 30 at a position on the front end side of the fastening jig 10. The slit 31 is provided from the upper end surface 30b to the lower end surface 30c of the guide portion 30 (see FIG. 8). Here, the slit 31 corresponds to a gap as recited in the claims. In other words, the guide portion 30 is a member whose cross section perpendicular to the extension direction of the guide portion 30 is arc-shaped.

[0021] The slit 31 of the guide part 30 is provided to change the relative position between the fastening jig 10 and the long screw 70 inserted into the internal space 30a of the guide part 30, thereby allowing the long screw 70 to retreat from the internal space 30a of the guide part 30 to the outside of the guide part 30 via the slit 31. Here, the slit 31 corresponds to a gap in the claims. Note that changing the relative position between the fastening jig 10 and the long screw 70 inserted into the internal space 30a of the guide part 30 means, for example, moving the fastening jig 10 in a direction intersecting the central axis of the long screw 70 (or the extending direction of the guide part 30).

[0022] Here, the guide portion 30 is a single member, but it may be a so-called telescopic guide portion that is made by combining arc-shaped members with different outer diameters and is extendable in the extending direction of the guide portion. In the case of a telescopic guide portion, it is necessary to provide a structure (mechanism) that prevents the positions of the slits provided in each of the arc-shaped members with different outer diameters from shifting in the circumferential direction.

[0023] Next, the details of the notch 24 provided in the protruding piece 23 and the guide portion 30 will be described. As shown in FIG. 3(a), the inner diameter D1 of the circular portion 24a constituting the notch 24 is the same as the inner diameter D2 of the guide portion 30. Furthermore, the inner diameters D1 and D2 are set to be equal to or larger than the outer diameter D3 of the body portion 72 of the long screw 70 or the outer diameter D4 of the threaded portion 73. Note that although the case where the inner diameters D1 and D2 are set to be the same is described, the inner diameters D1 and D2 do not necessarily have to be the same as long as the inner diameters D1 and D2 are equal to or larger than the outer diameter D3 of the body portion 72 of the long screw 70 or the outer diameter D4 of the threaded portion 73.

[0024] Furthermore, the width W1 of the straight portion 24b constituting the cutout portion 24 is set to be the same as the width W2 of the slit 31 provided in the guide portion 30. The widths W1 and W2 are set to be equal to or greater than the outer diameter D3 of the body portion 72 or the outer diameter D4 of the threaded portion 73 of the long screw 70 used to fasten the building panel 50 to the sheathing board 91. Although the case where the widths W1 and W2 are set to be the same is described above, as long as the widths W1 and W2 are equal to or greater than the outer diameter D3 of the body portion 72 of the long screw 70 or the outer diameter D4 of the threaded portion 73, the widths W1 and W2 do not necessarily have to be the same.

[0025] Incidentally, the long screws 70 include those in which the outer diameter D4 of the threaded portion 73 is the same as the outer diameter D3 of the body (cylindrical portion) 72, those in which the outer diameter D4 of the threaded portion 73 is smaller than the outer diameter D3 of the body (cylindrical portion) 72, and those in which the outer diameter D4 of the threaded portion 73 is larger than the outer diameter D3 of the body (cylindrical portion) 72.

[0026] For example, in the case of a long screw in which the outer diameter D4 of the threaded portion 73 is the same as the outer diameter D3 of the body (cylindrical portion) 72, or in the case of a long screw in which the outer diameter D4 of the threaded portion 73 is smaller than the outer diameter D3 of the body (cylindrical portion) 72, it is preferable that the above-mentioned widths W1 and W2 be set larger than the outer diameter D3 of the body (cylindrical portion) 72.

[0027] On the other hand, in the case of a long screw in which the outer diameter D4 of the threaded portion 73 is larger than the outer diameter D3 of the trunk (cylindrical portion) 72, it is preferable that the widths W1 and W2 described above be set larger than at least the outer diameter D3 of the trunk (cylindrical portion) 72. This is because it is conceivable that when the long screw 70 is tightened, the entire threaded portion 73 will penetrate into the building panel 50, leaving only the trunk (cylindrical portion) 72 exposed.

[0028] Furthermore, the length L1 from the center C1 of the circular portion 24a constituting the cutout portion 24 to the base of the cutout portion 24 is set as follows. 3(a) and Fig. 4(a) As shown in Fig. 1, the length L1 is set to be the same as the length L2 from one end surface 60a of the clip 60 in the eaves-ridge direction to the center C2 of one of two insertion holes 62, 62 provided in the tongue pieces 61, 61, which is located close to the one end. The outer surfaces 61a of the tongue pieces 61, 61 of the clip 60 function as bearing surfaces when the building panel 50 connected by the clip 60 is screwed to the sheathing board 91.

[0029] The guide portion 30 is exemplified as a member having an arc-shaped cross section perpendicular to the extending direction (vertical direction) of the guide portion 30. However, the guide portion 30 may be a member having a rectangular or U-shaped cross section.

[0030] FIG. 3(b) illustrates a case where the guide portion 30' is a member having a U-shaped cross section. As shown in FIG. 3(b), in this case, the width W1' of the notch 24' provided in the protruding piece 23' and the width W2' of the internal space 30a' of the guide portion 30' are set larger than the outer diameter D3 of the long screw 70. Note that the width W1' of the notch 24' provided in the protruding piece 23' and the width W2' of the internal space 30a' of the guide portion 30' only need to be set larger than the outer diameter D3 of the long screw 70, and may be the same width as or different from the width W2' of the internal space 30a' of the guide portion 30'. Note that FIG. 3(b) illustrates a case where the width W1' of the notch 24' and the width W2' of the internal space 30a' of the guide portion 30' are the same width. In this case, the outer diameter D3 of the long screw 70 is preferably either the outer diameter of the body portion 72 or the outer diameter of the threaded portion 73 of the long screw 70 shown in FIG.

[0031] 1 and 2, the grip portion 40 is a portion that is gripped by an operator. The grip portion 40 includes a grip tube 41 and support columns 42 and 43.

[0032] The gripping tube 41 is, for example, a cylindrical member. The length of the gripping tube 41 in the extending direction is set to a length that allows the gripping tube 41 to be disposed across each of the support columns 42 and 43 fixed to the metal plate 21, for example.

[0033] The support pillars 42, 43 are members that support the grip tube 41 from below. The support pillar 42 is fixed, for example, to the rear end side of the metal plate 21 of the pressing unit 20 and to the left end of the metal plate 21 in the left-right direction. The support pillar 43 is fixed, for example, to the rear end side of the metal plate 21 of the pressing unit 20 and to the right end of the metal plate 21 in the left-right direction. It is preferable that the lengths of the support pillars 42, 43 in the central axis direction are the same. In other words, when the grip tube 41 is fixed to the support pillars 42, 43, the extension direction of the grip tube 41 is parallel to the horizontal direction.

[0034] Incidentally, the positions at which the support columns 42 and 43 are fixed to the metal plate 21 of the pressing portion 20 are set to the rear end side of the metal plate 21 of the pressing portion 20, but it is not necessarily necessary to fix them to the rear end side of the metal plate 21 of the pressing portion 20.

[0035] Furthermore, when the gripping tube 41 is fixed to the support columns 42 and 43, the extension direction of the gripping tube 41 is, for example, parallel to the horizontal direction. However, as long as the worker can press the pressing part 20 against the building panel 50 while holding the gripping tube 41, the central axis direction of the gripping tube 41 does not need to be parallel to the horizontal direction.

[0036] Next, a procedure for fixing a building panel 50 to a sheathing board 91 (see FIG. 5) using the fastening jig 10 shown in this embodiment will be described. For example, a plurality of building panels 50 are arranged on the sheathing board 91 in the eaves-ridge direction and the girder direction. Of these building panels 50, vertical joints 52 are provided on the outer skin materials 51 of two building panels 50 adjacent in the girder direction, and clips 60 are attached to the upright pieces 53 provided on the two adjacent vertical joints 52. This links the two building panels 50 adjacent in the girder direction (see FIG. 4).

[0037] After the clips 60 are attached to the upright pieces 53, 53 provided on two adjacent vertical joints 52, 52, the worker grasps the gripping tube 41 of the fastening jig 10 and presses the fastening jig 10 against the exterior materials 51, 51 of the two adjacent building panels 50, 50. At this time, as shown in FIGS. 4( a) and 4(b), the position of the fastening jig 10 relative to the clip 60 is adjusted so that the center C1 of the circular portion 24a of the notch portion 24 of the protruding piece 23 coincides with the center C2 of the insertion hole 62 of the clip 60 in a top view of the clip 60 or the fastening jig 10. Note that when the center C1 of the circular portion 24a of the notch portion 24 coincides with the center C2 of the insertion hole 62 of the clip 60, the front end surface 20a of the pressing portion 20 of the fastening jig 10 abuts against one end surface 60a of the clip 60.

[0038] 5 and 6, a worker inserts a long screw 70 for fastening the building panel 50 from the upper end of the guide portion 30 of the fastening jig 10 into the internal space 30a. The long screw 70 inserted into the internal space 30a of the guide portion 30 moves along the guide portion 30. At this time, the tip of the long screw 70 passes through the internal space 30a of the guide portion 30, the circular portion 24a of the cutout portion 24, and the insertion hole 62 provided in the tongue piece 61 of the clip 60, in that order, and is abutted against the exterior material 51 of the building panel 50 (see FIG. 8).

[0039] The worker performs a punching process. The punching process is a process in which the head 71 of the long screw 70 is struck with a hammer, for example, to mark, for example, the exterior skin material 51 of the building panel 50. Note that the punching process may be omitted.

[0040] After the punching process, the worker inserts the tip of the bit 81 attached to the electric screwdriver 80 into the insertion hole 74 provided in the head 71 of the long screw 70. As shown in FIG. 7, the worker operates the electric screwdriver 80 while pressing the electric screwdriver 80 toward the building panel 50 (in the direction F1 in FIG. 7). As described above, the inner diameter D1 of the internal space 30a of the guide part 30 is set larger than the outer diameter D3 of the body part 72 of the long screw 70. Therefore, as shown in FIG. 8, when the electric screwdriver 80 is pressed toward the building panel 50, the long screw 70 may tip over, for example, in the direction F2. However, as the long screw 70 tip over, it is held in contact with the ridge line 30e between the upper end surface 30b and the inner peripheral surface 30d of the guide part 30. Therefore, the angle at which the long screw 70 tip over is suppressed.

[0041] By driving the electric screwdriver 80 while pressing it toward the building panel 50, the long screw 70 rotates together with the bit 81 of the electric screwdriver 80. As the long screw 70 rotates, the tip of the long screw 70 penetrates the exterior material 51 of the building panel 50 and enters the core material (insulating material) 54 of the building panel 50. Then, when the worker has tightened the long screw 70 by a predetermined amount by driving the electric screwdriver 80, the worker temporarily stops driving the electric screwdriver 80 (see FIG. 9 ). At this time, the lower end surface of the rubber washer 75 attached to the long screw 70 does not abut the upper end of the guide part 30. In this state, the worker moves the fastening jig 10 in the direction F3 in FIG. 9 . By moving the fastening jig 10 in the direction F3 in FIG. 9 , the long screw 70 retreats to the outside of the internal space 30a of the guide part 30 via the slit 31. In other words, the fastening jig 10 is removed from the long screw 70.

[0042] 10 , the worker inserts the tip of a bit 81 attached to an electric screwdriver 80 into an insertion hole 74 provided in the head 71 of the long screw 70, and drives the electric screwdriver 80 while pressing the electric screwdriver 80 toward the building panel 50 (in the direction of F1 in FIG. 10 ). As a result, the long screw 70 is tightened until the head 71 of the long screw 70 abuts against the outer surface 61 a of the tongue 61 of the clip 60. This screws the building panel 50 to the sheathing board 91. At this point, the long screw 70 has been tightened a predetermined amount into the building panel 50. Therefore, even if a pressing force is applied to the long screw 70 in a direction intersecting the tightening direction of the long screw 70 (the extension direction of the long screw 70) when the electric screwdriver 80 is used, the long screw 70 is tightened in the same direction as when the long screw 70 was tightened using the fastening jig 10. As shown in Fig. 11, the tip of the long screw 70 tightened by the electric screwdriver 80 penetrates a sheathing board 91 and is screwed into a rafter 92 supporting the sheathing board 91. Fig. 11 shows a case where the long screw 70 is tightened in a direction perpendicular to the outer surface 61a of the tongue piece 61 of the clip 60, which serves as the seating surface. In this way, by tightening the long screw 70 using the fastening jig 10 shown in this embodiment, it is possible to prevent the long screw 70 from falling over during the tightening operation.

[0043] In this embodiment, the metal plate has a rectangular shape in a plan view of the fastening jig 10. However, the shape of the metal plate is not limited to a rectangular shape as long as the extending direction of the guide portion 30 constituting the fastening jig 10 can be maintained in a direction perpendicular to the bearing surface when the screw is fastened. In other words, the shape of the metal plate constituting the pressing portion can be any appropriate shape, such as a home base shape or a U-shape cut out from the rear end to the front end.

[0044] In this embodiment, the configuration of the protruding piece 23 that protrudes forward from the center of the front end of the pressing portion 20 is exemplified, but the position at which the protruding piece 23 is provided is not limited to the center of the front end of the pressing portion 20.

[0045] This embodiment discloses a fastening jig 10 having a protruding piece 23 protruding forward from the center of the front end of a metal plate 21 constituting a pressing portion 20, and a guide portion 30 fixed to the upper surface of the protruding piece 23. However, the configuration of the protruding piece 23 is not necessarily required. That is, as shown in FIG. 12 , the fastening jig 100 has a pressing portion 120, a guide portion 130, and a gripping portion 140, similar to this embodiment. The pressing portion 120 is composed of a metal plate 121 and an anti-slip member 122 fixed to the bottom surface of the metal plate 121. In addition, a notch 123 is provided in the center of the front end of the pressing portion 120. The shape of the notch 123 is the same as the shape of the notch 24. The guide portion 130 and the gripping portion 140 have the same configurations as the guide portion 30 and the gripping portion 40 of the fastening jig 10 shown in this embodiment. The guide portion 130 is fixed to protrude above the metal plate 121 of the pressing portion 120 so that the internal space 130a communicates with the cutout portion 123. Using this fastening jig 100, the building panel 50 can be fastened to the sheathing board 91 with screws.

[0046] Although the example shows the case where the guide portion 130 is fixed to the center of the front end of the pressing portion 120, the position at which the guide portion 130 is fixed is not limited to the center of the front end of the pressing portion 120.

[0047] In this embodiment, the guide portion 30 is fixed to the upper surface of the protruding piece 23 that protrudes forward from the metal plate 21 of the pressing portion 20, or the guide portion 130 is fixed to the front end portion of the metal plate 121 of the pressing portion 120. However, a connecting member such as a connecting arm may be used to connect the pressing portion and the guide portion, and the guide portion may be fixed to the pressing portion.

[0048] In this embodiment, a fastening jig is described that is used when screwing a building panel to a sheathing board 91. However, the fastening jig of this embodiment can also be used when fixing a building panel to a sheathing board 91 using nails instead of long screws.

[0049] Furthermore, the fastening jig shown in this embodiment is a fastening jig used when screwing a building panel to a sheathing board 91, but the parts to be screwed are not limited to building panels.

[0050] In this embodiment, the guide portion has a cylindrical shape, but as long as it can guide the insertion direction of the long screw, it does not have to be limited to a cylindrical shape and may be a rectangular tube shape such as a triangular tube or a square tube.

[0051] <Summary of effects> The fastening jig 10 of this embodiment is a fastening jig 10 used when fastening a building panel 50 to a sheathing board 91 using a long screw 70, and includes a pressing portion 20 that is pressed against the outer surface of the building panel 50 when fastening the building panel 50 to the sheathing board 91, a gripping portion 40 that is gripped by a worker when pressing the pressing portion 20 against the outer surface of the building panel 50, and an internal space 30a whose extension direction is a direction intersecting with the outer surface of the building panel 50 and whose both ends in the extension direction are open, and and a guide portion 30 that guides the long screw 70 inserted into the internal space 30a from one end thereof toward the building material panel 50, the guide portion 30 extending along the extension direction of the guide portion 30 from one end to the other end in the extension direction of the guide portion 30, and having a slit 31 that allows the long screw 70 inserted into the internal space 30a to retreat from the internal space 30a of the guide portion 30 to the outside when the pressing portion 20 is moved in a direction intersecting the extension direction of the guide portion 30.

[0052] This makes it possible to prevent the long screws 70 from tipping over when screwing the building panel 50 to the sheathing board 91 using a tool such as an electric screwdriver 80, without having to drill pilot holes using an electric drill. Also, since there is no need to drill pilot holes, it is possible to improve the efficiency of roofing work. [Explanation of symbols]
