Description

[Technical Field]

[0001] The present invention relates to a guide member and a guide method, and more particularly to a guide member and a guide method that are used to drive a rod-shaped fastening member into a wall surface and guide the fastening member. [Background technology]

[0002] For example, when repairing the exterior walls of a building, it is known to drive rod-shaped fastening members into the wall surface (see, for example, Patent Document 1). Patent Document 1 discloses a method for repairing an existing exterior wall, in which screws are driven into the existing exterior wall via washers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-25038 Summary of the Invention [Problem to be solved by the invention]

[0004] It is desirable to drive rod-shaped fasteners such as screws perpendicularly into a wall surface. However, in Patent Document 1, the user must hold the fastener in their hand while driving it into the wall, which can cause the angle of the fastener relative to the wall to be unstable and the fastener to be driven at an angle relative to the wall. To address this issue, a guide member can be used to drive the fastener perpendicularly into the wall. However, such a guide member must be removed after the fastener has been driven a certain amount.

[0005] Therefore, the present invention has been made in consideration of the above-mentioned problems, and its object is to provide a guide member that can drive a fastening member vertically into a wall surface and that can be removed after a certain amount of the fastening member has been driven in, and a guiding method using the guide member. [Means for solving the problem]

[0006] The above object is achieved by the guide member of the present invention, which is used to drive rod-shaped fastening members into a wall surface and guides the fastening members, and which comprises a base portion that makes surface contact with the wall surface, and a holding portion that extends in a direction perpendicular to the base portion and engages with the outer periphery of the shank of the fastening member in a state that is detachable from the shank, thereby holding the fastening member in a perpendicular position to the wall surface, and the holding portion has an opening that is continuous from one end to the other in the extension direction of the holding portion, and is configured to be detached from the shank by elastically deforming so that the width of the opening increases when the holding portion engages with the outer periphery of the shank.

[0007] In the guide member of the present invention, the holding portion engages with the outer periphery of the shank of the fastening member, thereby holding the fastening member in a perpendicular position relative to the wall surface. Furthermore, the holding portion can be removed from the shank by elastically deforming the opening so that the width of the opening increases. This allows the fastening member to be driven perpendicularly into the wall surface, and the guide member can be removed after a certain amount of fastening has been driven in.

[0008] The opening may include a first opening portion and a second opening portion having different widths. With the above configuration, the retaining portion can be properly engaged with the outer periphery of the shaft portion at the location adjacent to the opening portion with a smaller width, while the retaining portion can be properly removed from the shaft portion through the opening portion with a larger width.

[0009] Additionally, the first opening portion, which has a smaller width, may be farther from the base portion than the second opening portion. With the above configuration, the holding portion can engage with the outer periphery of the shank over a larger area at positions farther from the base than at positions closer to the base, thereby preventing the fastener from shifting position at positions farther from the base, and allowing the fastener to be properly held perpendicular to the wall surface.

[0010] The base portion may extend outward beyond the outer edge of the holding portion, and may be provided with a notch that is continuous with the opening. With the above configuration, after the fastening member has been driven in by a certain amount, the guide member can be appropriately removed from the fastening member via the opening and the notch.

[0011] In addition, the wall surface may be the outer surface of an extension member extending in a predetermined direction, and the base portion may include an attachment portion that is attachable to the extension member and that is movable in the extension direction of the extension member while attached to the extension member. With the above configuration, the guide member can be easily installed at an appropriate position on the wall surface by moving the attachment portion along the extending direction of the extending member.

[0012] Furthermore, the above-mentioned problems are solved by the guide method of the present invention, which is used to drive rod-shaped fastening members into a wall surface and guides the fastening members, and includes an installation step of installing a guide member having a base portion and a holding portion extending in a direction perpendicular to the base portion on the wall surface with the base portion in surface contact with the wall surface; a holding step of holding the fastening member in a perpendicular position to the wall surface by engaging the holding portion with the outer periphery of the shaft portion in a state in which it is detachable from the shaft portion of the fastening member; a driving step of driving the fastening member into the wall surface; and a removal step of detaching the holding portion from the shaft portion by elastically deforming the holding portion so that the width of an opening that is continuous from one end to the other end in the extension direction of the holding portion increases. According to the above-described guide method, the guide member is used so that the fastening member can be driven perpendicularly into the wall surface, and the fastening member can be removed after being driven a certain amount.

[0013] In addition, in the above-mentioned guide method, in the installation process, the guide member may be installed on the wall surface with the opening and the notch portion continuous with the opening provided in the base portion that extends outward beyond the outer edge of the holding portion facing upward. With the above method, after the fastening member has been driven in by a certain amount, the guide member can be pulled out downward (in the direction of gravity), and the guide member can be easily removed from the fastening member.

[0014] The above-described guide method may further include, before the installation step, a modification step of modifying the position of the wall surface by increasing at least one of the exterior material and the heat insulating material on the inner side of the wall surface. With the above method, even if the position of the wall surface is changed and the length of the shank of the fastening member becomes longer, the fastening member can be driven perpendicularly into the wall surface. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide a guide member that can drive a fastening member vertically into a wall surface and that can be removed after a certain amount of the fastening member has been driven in, and a guide method using the guide member.

[0017] One embodiment of the present invention (hereinafter referred to as the present embodiment) will be described in detail below with reference to a preferred embodiment shown in the accompanying drawings. Note that the following embodiment is merely an example given to facilitate understanding of the present invention and is not intended to limit the present invention. In other words, the configuration of the present invention may be modified or improved from the following embodiment without departing from the spirit of the present invention. In addition, the drawings show each component somewhat simplified and schematic to make the explanation easier to understand, and the size (dimensions) of each component and the spacing between components shown in the drawings may differ from the actual ones. Furthermore, unless otherwise specified, the material and shape of each member used to implement the present invention can be set arbitrarily depending on the application of the present invention and the state of the art at the time of implementing the present invention. Furthermore, "orthogonal," "vertical," and "horizontal" include the range of error generally accepted in the technical field of the present invention, and also include states where the deviation is within a range of several degrees (e.g., 5° to 10°) from the strict "orthogonal," "vertical," and "horizontal." In this specification, of the three mutually orthogonal directions, the direction perpendicular to the outer surface (corresponding to the wall surface Ws) of the furring strip M5 (corresponding to the extension member) described later in Figure 1 is referred to as the "first direction," the width direction of the furring strip M5 is referred to as the "second direction," and the direction in which the furring strip M5 extends is referred to as the "third direction." In this specification, the "first direction" and "second direction" correspond to the horizontal direction, the "third direction" corresponds to the up-down direction (vertical direction), the "lower side (one side of the third direction)" corresponds to the direction of gravity, and the "upper side (the other side of the third direction)" corresponds to the opposite side to the direction of gravity.

[0018] <<Configuration of the guide member according to this embodiment>> A guide member according to this embodiment (hereinafter referred to as guide member 10) will be described with reference to FIGS. In the following explanation, it is assumed that the guide member 10 is installed on a wall W (more specifically, a furring strip M5, which will be described later). In other words, unless otherwise specified, the normal use state of the guide member 10, i.e., the state in which the guide member 10 is installed on the wall W (the state in FIG. 1), is assumed. When explaining the position of the guide member 10, as well as the orientation and extension direction of each part of the guide member 10, the position of the guide member 10 when the guide member 10 is in the normal use state, as well as the orientation and extension direction of each part of the guide member 10, will be shown.

[0019] As shown in Figure 1, the guide member 10 is used, for example, to drive a rod-shaped fastening member S into the wall surface Ws of the wall W (in this embodiment, the outer surface of the furring strip M5), and guides the fastening member S. Examples of the wall W include the exterior wall of a building, and examples of the building include buildings for various purposes such as homes, nursing homes, offices, stores, hospitals, schools, and other facilities, as well as buildings in factories. The wall W is not limited to the exterior wall of a building, and may be any wall, regardless of the field of use, purpose, structure, shape, etc., and may be, for example, a wall used for purposes other than buildings (for example, a wall that constitutes the housing of a device, etc.). In this embodiment, the wall surface Ws is the outer surface of the furring strip M5 extending in the vertical direction (corresponding to the specified direction), but is not limited to this and may be any wall surface. In this embodiment, the wall W corresponds to, for example, an exterior wall to be renovated (remodeled, etc.), and specifically, as shown in Figure 1, is constructed by adding a new additional part Ne to the outside of the existing part Ex.

[0020] In the example shown in Fig. 1, the existing portion Ex is composed of multiple frames M1 (only one frame M1 is shown in Fig. 1) extending in the vertical direction (third direction) and arranged at intervals in the second direction, plywood M2 arranged on the outer side of the building than the frames M1, and plate-like exterior wall material M3 arranged on the outer side of the building than the plywood M2. Examples of the frame M1 include a steel frame and crosspieces. The additional portion Ne is composed of a plate-shaped insulating material M4 arranged on the outer side of the building relative to the exterior wall material M3, and a plurality of furring strips M5 (corresponding to extension members) arranged on the outer side of the building relative to the insulating material M4 and extending in the vertical direction. Note that only one of the plurality of furring strips M5 is shown in FIG. 1. The multiple furring strips M5 are spaced apart in the second direction, and the positions of the furring strips M5 in the second direction are the same as the positions of the frames M1. That is, when viewed from the first direction, the furring strips M5 are arranged in positions that overlap the frames M1. The width (length in the second direction) of the furring strips M5 is, for example, 180 mm. Note that the insulating material M4 may be, for example, an exterior material, and the existing portion Ex may include, in addition to the furring strips M5, at least one of the insulating material M4 and the exterior material.

[0021] The fastening member S is, for example, a screw, and is composed of a head portion Sh (a screw head) and a shaft portion Sx extending from the head portion Sh, with a threaded portion formed on at least a portion of the shaft portion Sx. The length of the shaft portion Sx is, for example, 100 mm to 200 mm, and the diameter of the shaft portion Sx is, for example, 4 mm to 8 mm (equivalent to M4 to M8 in the case of a metric screw). The type of fastening member S may vary depending on the material of the wall surface Ws. Specifically, if the wall surface Ws is a wooden surface, the fastening member S may be a fastening member for wood, or if the wall surface Ws is a metal surface, the fastening member S may be a fastening member for metal. Alternatively, the fastening member S may be a fastening member that can be used on both wooden and metal surfaces.

[0022] The guide member 10 is used to drive the fastening member S perpendicularly into the wall surface Ws of the wall W configured as described above. More specifically, as shown in Fig. 2, the guide member 10 includes a base portion 20 that comes into surface contact with the wall surface Ws, and a holding portion 30 that extends from the base portion 20 in a first direction (a direction perpendicular to the base portion 20).

[0023] <Holding part> First, the holding portion 30 will be described. 2, the holding portion 30 is detachably attached to the shank Sx of the fastening member S and engages with the outer periphery of the shank Sx to hold the fastening member S in a position perpendicular to the wall surface Ws. Specifically, the holding portion 30 has a holding main body 31, an extending portion 32, and a protruding portion 33.

[0024] As shown in Fig. 3, when viewed from the first direction, the holding body 31 is adjacent to the shank Sx from below (one side in the third direction) and extends in a curved manner along the lower part of the outer periphery of the shank Sx. In other words, when viewed from the first direction, the holding body 31 extends in the circumferential direction of an imaginary circle C centered on a reference point (corresponding to the position of the central axis of the shank Sx) within a lower range (more specifically, a lower half range) of the imaginary circle C. In this embodiment, as shown in Fig. 3, the dimension in the second direction of the internal space surrounded by the curved holding body 31 is set according to the size of the shank Sx, and is, for example, slightly larger than the diameter of the shank Sx (for example, 0.5 mm to 1.5 mm larger than the diameter of the shank Sx). As shown in FIG. 2, the holding body 31 has a plate shape extending in the first direction, and in this embodiment, the dimension of the holding body 31 in the first direction is, for example, 20 mm to 40 mm.

[0025] The extension portion 32 extends upward (to the other side in the third direction) from the holding main body portion 31, and specifically, as shown in Fig. 3, is composed of a first extension portion 34 and a second extension portion 35 that are spaced apart from each other in the second direction. The first extension portion 34 is a plate-like portion that extends linearly upward from one end of the holding main body portion 31 in the extension direction (the direction along the imaginary circle C). The second extension portion 35 is a plate-like portion that extends linearly upward from the other end of the holding main body portion 31 in the extension direction. In this embodiment, the shape formed by the holding main body 31 and the extending portion 32, when viewed from the first direction, is a U-shape that opens upward, as shown in Fig. 3. In this embodiment, the length in the vertical direction of the holding main body 31 and the extending portion 32, that is, the length in the vertical direction from the lower end of the holding main body 31 to the upper end of the extending portion 32, is, for example, 10 mm to 15 mm.

[0026] As shown in Fig. 3, the protruding portion 33 is a plate-like portion that protrudes from the boundary between the holding body portion 31 and the first extending portion 34 as a base end toward the internal space surrounded by the holding body portion 31 and the extending portion 32. More specifically, the protruding portion 33 protrudes along an upper portion of the outer periphery of the shaft portion Sx when viewed from the first direction. In other words, the protruding portion 33 protrudes from the first extending portion 34 toward the second extending portion 35 along the circumferential direction of an imaginary circle C in an area above the imaginary circle C when viewed from the first direction. The tip of the protruding portion 33 is spaced a predetermined distance from the second extending portion 35, thereby forming an opening 44 (described later) between the protruding portion 33 and the second extending portion 35, as shown in Fig. 3.

[0027] As shown in Figure 2, in the first direction, the protruding portion 33 protrudes from a portion of the entire range from one end 41 (the end opposite the base portion 20) of the holding main body portion 31 (holding portion 30) to the other end 42 (the end on the base portion 20 side), and in this embodiment, is located from the one end 41 to the center position of the holding main body portion 31. More specifically, as shown in FIG. 2 , the protruding portion 33 is composed of a first protruding portion 36 and a second protruding portion 37 that is located closer to the base portion 20 in the first direction than the first protruding portion 36 and is continuous with the first protruding portion 36. The first protruding portion 36 and the second protruding portion 37 have different widths. Specifically, the width of the second protruding portion 37 is smaller than the width of the first protruding portion 36. Note that the "width" corresponds to the width in a direction perpendicular to the first direction (the second direction in this embodiment). The first protruding portion 36 has a constant width regardless of its position in the first direction, and the width of the second protruding portion 37 decreases as it moves closer to the base portion 20 in the first direction.

[0028] The holding portion 30 configured as described above may be configured by integrally (seamlessly) forming the holding body portion 31, the extending portion 32, and the protruding portion 33. Alternatively, the holding portion 30 may be configured by joining the holding body portion 31, the extending portion 32, and the protruding portion 33 by welding, adhesive, or fastening with screws or the like. Examples of materials for the holding part 30 include metal materials, resin materials, and rubber materials, and specifically may be thermoplastic polyurethane (TPU) as a rubber material. The hardness of the holding part 30 is preferably, for example, a Shore hardness of 60A to 95A, more preferably a Shore hardness of 90A to 95A, and even more preferably a Shore hardness of 95A.

[0029] In this embodiment, the holding body 31, the extending portion 32, and the protruding portion 33 are integrally formed using a rubber material such as TPU as a molding material, for example, in a three-dimensional modeling device (3D printer), and the holding portion 30 is capable of elastic deformation. In particular, as shown in Fig. 3, when a predetermined force is applied from one side in the vertical direction, the protruding portion 33 is capable of rotating while elastically deforming toward the side opposite to the side to which the predetermined force is applied, with the base end portion of the protruding portion 33 (the boundary portion between the holding body 31 and the first extending portion 34) as the base point (rotation center).

[0030] The holding portion 30 configured as described above is engaged with the outer periphery of the shank Sx of the fastening member S in a state in which it can be attached to and detached from the shank Sx, as shown in FIG. The state in which the holding portion 30 is engaged with the outer periphery of the shank Sx will be described in more detail with reference to FIG. 3 . In this embodiment, before the shank Sx of the fastening member S is inserted (attached) to the holding portion 30, the vertical distance (maximum distance) between the holding body 31 and the protruding portion 33 is, for example, slightly smaller than the diameter of the shank Sx. However, when the shank Sx is inserted between the holding body 31 and the protruding portion 33, the protruding portion 33 elastically deforms upward, and the distance between the holding portion 30 and the shank Sx expands to approximately the same as the diameter of the shank Sx. As a result, the shank Sx receives a repulsive force from the protruding portion 33 due to elastic deformation, and as a result, the holding portion 30 is engaged with the outer periphery of the shank Sx. Note that the shank Sx of the fastening member S can be pulled out (removed) from the holding portion 30 against the repulsive force. Therefore, the holding portion 30 can be said to be detachable from the shank Sx of the fastening member S. In this way, the holding portion 30 is capable of engaging with the outer circumferential portion of the shank Sx of the fastening member S in a state in which it is detachable from the shank Sx. In the above description, before the shank Sx is inserted into the holder 30, the vertical distance (maximum distance) between the holder main body 31 and the protruding portion 33 is slightly smaller than the diameter of the shank Sx. However, this is not limited to this, and for example, the distance may be approximately the same as the diameter of the shank Sx or slightly larger than the diameter of the shank Sx. Even in this case, the holder 30 can be engaged with the outer periphery of the shank Sx in a state where it is detachable from the shank Sx.

[0031] The thickness of the retaining portion 30, more specifically, the thickness (plate thickness) of each of the retaining body portion 31, the extending portion 32, and the protruding portion 33, may be such that the retaining portion 30 can be removed from the shaft portion Sx by elastic deformation of the retaining portion 30, and may be set appropriately depending on the material, size, shape, etc. of the retaining portion 30. The size of the retaining portion 30 may be set appropriately depending on the size of the fastening member S.

[0032] <Opening> To further explain the retaining portion 30 from another perspective, when viewed from the first direction, as shown in Figure 3, the retaining portion 30 is open in a portion of the entire range in the circumferential direction of the imaginary circle C (in this embodiment, the upper portion), and it can be said that this open portion has an opening 44. As shown in Figure 2, the opening 44 extends continuously from one end 41 to the other end 42 in the first direction (the extension direction of the holding portion 30), and more specifically, includes a first opening portion 45 and a second opening portion 46 which have different widths and are aligned in the first direction.

[0033] 2, the first opening portion 45 is located farther from the base portion 20 in the first direction than the second opening portion 46, and corresponds to the opening portion formed between the protruding portion 33 and the second extending portion 35. More specifically, the first opening portion 45 has a constant width B1 in the range adjacent to the first protruding portion 36, and the width B1 is smaller than the diameter of the shank Sx, for example (e.g., about half the diameter of the shank Sx). On the other hand, in the range adjacent to the second protruding portion 37, the width of the first opening portion 45 increases toward the base portion 20, and the maximum width in that range is, for example, about the same as the diameter of the shank Sx.

[0034] The second opening portion 46 is located closer to the base portion 20 in the first direction than the first opening portion 45, and corresponds to the opening portion formed between the first extending portion 34 and the second extending portion 35. The second opening portion 46 has a constant width B2 regardless of its position in the first direction, and the width B2 is approximately the same as the diameter of the stem portion Sx or slightly larger than the diameter of the stem portion Sx (for example, 0.5 mm to 1.5 mm larger than the diameter of the stem portion Sx). 2, the width B2 of the second opening portion 46 is larger than the width B1 of the first opening portion 45, at least the width of the range of the first opening portion 45 that is adjacent to the first protruding portion 36. In other words, the first opening portion 45, which has a smaller width, is located farther from the base portion 20 than the second opening portion 46.

[0035] The holding portion 30 configured as described above is configured to be detached from the shaft portion Sx by elastically deforming so that the width of the opening 44 increases while the holding portion 30 is engaged with the outer peripheral portion of the shaft portion Sx. More specifically, as shown in Figure 3, when the holding part 30 is moved downward relative to the shaft part Sx from a state in which the holding part 30 is engaged with the outer periphery of the shaft part Sx, the protruding part 33 begins to rotate upward while elastically deforming, with its base end part (the boundary part between the holding main body part 31 and the first extending part 34) as the base point. As a result, the width of the opening 44 begins to widen. When the holding part 30 is further moved downward relative to the shaft part Sx and the width of the opening 44 becomes equal to or greater than the diameter of the shaft part Sx, the holding part 30 is detached from the shaft part Sx.

[0036] 2, both ends (one end 41 and the other end 42) of the holding portion 30 in the first direction are open. Because one end 41 of the holding portion 30 (the end opposite the base portion 20) is open, it is possible to insert the shank Sx of the fastening member S into the holding portion 30 from the one end 41. Moreover, because the other end 42 of the holding portion 30 (the end on the base portion 20 side) is open, it is possible to drive the tip of the shank Sx held by the holding portion 30 into the wall surface Ws through the other end 42.

[0037] <Base part> As shown in FIG. 2, the base portion 20 has a base main body portion 21, a notch portion 22, and an attachment portion 23.

[0038] The base main body portion 21 has a flat plate shape that conforms to the wall surface Ws, and as shown in Fig. 3, when viewed from the first direction, it protrudes outward beyond the outer edge 43 of the holding portion 30. More specifically, when viewed from the first direction, the base main body portion 21 protrudes outward beyond the outer edge 43 of the holding portion 30 on both sides in the up-down direction. Furthermore, when viewed from the first direction, the base main body portion 21 protrudes outward beyond the outer edge 43 of the holding portion 30 on both sides in the second direction. Note that, as shown in Fig. 3, the base main body portion 21 protrudes outward beyond the end of the furring strip M5 in the second direction. In this embodiment, the base main body portion 21 is rectangular when viewed from the first direction, but is not limited to this and may be, for example, circular (see, for example, base portion 20C in Figure 7), elliptical, a quadrangle other than a rectangle, a polygon other than a quadrangle, or an irregular shape.

[0039] 2, the cutout portion 22 is located above the holding portion 30 in the up-down direction, and is provided in the base main body portion 21. More specifically, the cutout portion 22 is formed by cutting out the upper end of the base main body portion 21, and extends from the upper end toward the holding portion 30 and is continuous with the opening 44 of the holding portion 30. The width of the notch 22 is set according to the size of the shaft portion Sx, and is, for example, slightly larger than the diameter of the shaft portion Sx (for example, 0.5 mm to 1.5 mm larger than the diameter of the shaft portion Sx).

[0040] As shown in Figure 2, the mounting portion 23 can be attached to the furring strip M5 extending along the wall W, and can move in the vertical direction (extension direction of the furring strip M5) while attached to the furring strip M5. More specifically, as shown in FIG. 2, the attachment portion 23 is made up of a first plate portion 24 and a second plate portion 25 that are spaced apart from each other in the second direction. The first plate portion 24 is plate-shaped and extends from one end of the base main body portion 21 in the second direction toward the opposite side of the holding portion 30 in the first direction, and has, for example, a rectangular shape when viewed from the second direction. The second plate portion 25 is plate-shaped and extends from the other end of the base main body portion 21 in the second direction toward the opposite side of the holding portion 30 in the first direction, and has, for example, a rectangular shape when viewed from the second direction. Note that the shapes of the first plate portion 24 and the second plate portion 25 are not limited to a rectangle, and may be, for example, a circle, an ellipse, a quadrangle other than a rectangle, a polygon other than a quadrangle, or an irregular shape. The distance in the second direction between the first plate portion 24 and the second plate portion 25 may be, for example, approximately the same as the width of the furring strip M5 or slightly larger than the width of the furring strip M5. This allows the attachment portion 23 to move smoothly in the up and down direction along the furring strip M5.

[0041] The base portion 20 configured as described above may be configured by integrally (seamlessly) forming the base main body portion 21, the notch portion 22, and the attachment portion 23. Alternatively, the base portion 20 may be configured by joining the base main body portion 21, the notch portion 22, and the attachment portion 23 by welding, adhesive bonding, or fastening with screws or the like. In addition, the base portion 20 may be formed integrally (seamlessly) with the holding portion 30; in other words, the guide member 10 may be constructed by forming the base portion 20 and the holding portion 30 integrally. The material of the base portion 20 is the same as that of the holding portion 30, and examples of the material include metal materials, resin materials, and rubber materials, and may be the same material as that of the holding portion 30 or a different material from that of the holding portion 30. Details of the material of the base portion 20 are the same as those of the holding portion 30, so a detailed explanation will be omitted. In this embodiment, the base portion 20 and the holding portion 30 are integrally formed using a rubber material such as TPU as a modeling material, for example, by a three-dimensional modeling device (3D printer).

[0042] <<Guide method according to this embodiment>> Next, a guiding method according to this embodiment will be described with reference to FIGS. The guide method according to this embodiment is used to drive a rod-shaped fastening member S into a wall W, and is a guide method for guiding the fastening member S, specifically, a guide method using the above-described guide member 10. As shown in Fig. 4, the guide method according to this embodiment includes a changing step, an installing step, a holding step, a driving step, and a removing step.

[0043] The modification process is a process performed before the installation process, in which at least one of the exterior material and the insulating material is added to the rear side of the wall Ws to change the position of the wall Ws. More specifically, in the modification process, as shown in FIG. 1 , an additional portion Ne including the insulating material M4 is placed from the outside of the building relative to the existing portion Ex of the wall W, thereby changing the position of the wall Ws in the first direction to a position further outward from the building. Note that although the guiding method according to this embodiment includes the modification process, this is not limited thereto. For example, the method may be performed starting from the installation process described below without performing the modification process. The installation process is a process of installing the guide member 10 on the wall surface Ws, and more specifically, the guide member 10 is installed on the wall surface Ws with the base portion 20 in surface contact with the wall surface Ws. In the installation process, as shown in Fig. 3, for example, the guide member 10 is installed on the wall surface Ws with the opening 44 and the notch portion 22 continuous with the opening 44 facing upward. Also, in the installation process, as shown in Fig. 1, for example, the mounting portion 23 of the guide member 10 is attached to the furring strip M5, and then the guide member 10 is moved in the vertical direction along the furring strip M5 to install the guide member 10 at a desired position in the vertical direction.

[0044] In the holding step, the holding portion 30 is detachably engaged with the outer periphery of the shank Sx of the fastening member S, thereby holding the fastening member S in a position perpendicular to the wall surface Ws. More specifically, in the holding step, the shank Sx is inserted from one end 41 (the end opposite the base portion 20) of the holding portion 30, and the tip of the shank Sx is advanced to the other end 42 (the end on the base portion 20 side) of the holding portion 30, and the fastening member S is held in a position perpendicular to the wall surface Ws with the tip of the shank Sx in contact with the wall surface Ws. The driving step is a step of driving the fastening member S into the wall surface Ws, and involves, for example, using a predetermined tool (for example, an impact driver) to rotate the top part Sh of the fastening member S, thereby driving the shank Sx into the wall surface Ws while rotating the shank Sx. Note that during the driving step, the user may hold down the base part 20 with a finger or a tool, etc., which can further stabilize the posture of the fastening member S during the driving step.

[0045] The removal process is a process of removing the guide member 10 from the fastening member S after the fastening member S has been driven in a certain amount in the driving process. Specifically, the holding part 30 is removed from the shank Sx by elastically deforming the holding part 30 so that the width of the opening 44 provided in the holding part 30 increases. Note that the "certain amount" refers to a driving amount that allows the fastening member S to stand on its own against the wall surface Ws. In the removal process, the guide member 10 can be removed from the fastening member S, which has been driven into the wall surface Ws and fixed to the wall surface Ws, by, for example, tilting the guide member 10 and pulling it downward. More specifically, as shown in FIG. 2, the holder 30 has a second opening 46 on the base 20 side. As described above, the width of the second opening 46 is approximately the same as or slightly larger than the diameter of the shaft Sx. Therefore, as shown in FIG. 4, for example, by rotating one end 42 of the holder 30 downward from one end 41 (the end opposite the base 20) of the holder 30, a portion of the shaft Sx enters the second opening 46. Furthermore, by rotating the guide member 10, a portion of the shaft Sx closer to the top Sh than the portion of the shaft Sx enters the first opening 45 from the second opening 46. At this time, the outer circumferential portion of the shaft Sx presses against the protruding portion 33, causing the protruding portion 33 to elastically deform. Finally, when the width of the first opening 45 becomes equal to or larger than the diameter of the shaft Sx, the holder 30 can be removed from the shaft Sx.

[0046] 2, in the range of first opening portion 45 adjacent to second protruding portion 37, the width of first opening portion 45 gradually decreases with increasing distance from base portion 20. Therefore, shaft portion Sx can be smoothly inserted from second opening portion 46 into the range of first opening portion 45 adjacent to first protruding portion 36.

[0047] <<Operations and Effects of the Guide Member and Guide Method According to the Present Embodiment>> As described above, in the guide member 10, as shown in Fig. 2, the holding portion 30 engages with the outer periphery of the shank Sx of the fastening member S, thereby holding the fastening member S in a position perpendicular to the wall surface Ws. In addition, the holding portion 30 can be removed from the shank Sx by elastically deforming the opening 44 so that the width of the opening 44 increases. This allows the guide member 10 to drive the fastening member S perpendicular to the wall surface Ws, and allows the fastening member S to be removed after being driven a certain amount. In particular, when fastening members S are driven into a wall surface Ws of an exterior wall that has a new additional portion Ne added outside an existing portion Ex, such as a wall W, the length of the fastening members S becomes longer by the thickness of the additional portion Ne. This makes it more difficult to drive the fastening members S perpendicularly into the wall surface Ws, as the position of the fastening members S becomes less stable when the fastening members S are driven in. Even in such a case, the guide member 10 can hold the fastening members S in a position perpendicular to the wall surface Ws by engaging the holding portion 30 with the outer periphery of the shaft portion Sx. Furthermore, for example, when a fastening member S that can be used for both wood and metal (a fastening member that can be used for both wood and metal surfaces) is used to drive the fastening member S into a wall surface Ws made of wood, the posture of the fastening member S may not be stable when the fastening member S is driven in, making it difficult to drive the fastening member S perpendicular to the wall surface Ws. Even in such a case, the guide member 10 can hold the fastening member S in a posture perpendicular to the wall surface Ws by engaging the holding portion 30 with the outer periphery of the shaft portion Sx.

[0048] As shown in FIG. 2, the opening 44 includes a first opening portion 45 and a second opening portion 46 that have different widths. This ensures a sufficient width for the portion adjacent to the first opening portion 45, which has a smaller width, i.e., the protruding portion 33, and ensures a sufficient contact area between the outer periphery of the fastening member S and the protruding portion 33. This allows the retaining portion 30 to be properly engaged with the outer periphery of the shank Sx.

[0049] In particular, the first opening portion 45, which has a smaller width, is farther from the base portion 20 than the second opening portion 46. This allows the holding portion 30 to engage with the outer circumferential portion of the shaft portion Sx over a larger area at a position farther from the base portion 20 than at a position closer to the base portion 20. More specifically, assume that the holder 30 is used to prevent the fastener S from shifting in the direction (vertical direction and second direction) along the wall surface Ws. In this case, preventing the fastener S from shifting at a position farther from the base 20 can reduce the angle of inclination of the fastener S from its perpendicular position relative to the wall surface Ws, even if the same amount of misalignment (e.g., 1 mm) is prevented, compared to preventing the fastener S from shifting at a position closer to the base 20. In other words, preventing the fastener S from shifting at a position farther from the base 20 can hold the fastener S more perpendicular to the wall surface Ws. Furthermore, by engaging the holder 30 with a larger area of ​​the outer periphery of the shank Sx, the fastener S can be appropriately prevented from shifting. In this way, the guide member 10 can suppress displacement of the fastening member S at a position farther away from the base portion 20, and therefore can properly hold the fastening member S in a position perpendicular to the wall surface Ws.

[0050] On the other hand, in the guide member 10, the holding portion 30 can be appropriately removed from the shaft portion Sx through the second opening portion 46, which has a larger width. 2, the second opening 46 is located closer to the base portion 20 in the first direction than the first opening 45. As a result, after a certain amount of fastening member S has been driven in, the guide member 10 can be pulled downward while tilting it relative to the fastening member S, as described above, thereby allowing the guide member 10 to be properly removed from the fastening member S. Specifically, by rotating the guide member 10 relative to the fastening member S, a portion of the shank Sx enters the second opening portion 46. Furthermore, by rotating the guide member 10, a portion of the shank Sx that is closer to the top Sh than the portion of the shank Sx described above enters the first opening portion 45, and when the width of the first opening portion 45 becomes equal to or greater than the diameter of the shank Sx, the holding part 30 can be removed from the shank Sx.

[0051] As described above, in this embodiment, when the holding portion 30 is engaged with the outer circumferential portion of the shaft portion Sx, the guide member 10 cannot be easily removed from the fastening member S. On the other hand, when removing the guide member 10 from the fastening member S, as described above, the guide member 10 can be easily removed from the fastening member S by changing the posture (angle, direction, etc.) of the guide member 10 to a posture different from the state in which the guide member 10 and the fastening member S are engaged.

[0052] 2, the base portion 20 extends outward beyond the outer edge 43 of the holding portion 30, and the base portion 20 is provided with a notch 22 that is continuous with the opening 44. This allows the guide member 10 to be properly removed from the fastening member S via the opening 44 and the notch 22 after a certain amount of the fastening member S has been driven in. As shown in FIG. 2 , the wall surface Ws is the outer surface of the furring strips M5, which extend vertically. The base portion 20 is attachable to the furring strips M5 and has an attachment portion 23 that can move in the extension direction (vertical direction) of the furring strips M5 while attached to the furring strips M5. This allows the guide member 10 to be easily installed at an appropriate position on the wall surface Ws by moving the attachment portion 23 along the extension direction of the furring strips M5. The "appropriate position" refers to, for example, a position corresponding to the fastening points S that are preset at a predetermined interval in the extension direction of the furring strips M5. When installing the guide member 10 on the wall surface Ws, it is necessary to adjust not only the position of the guide member 10 in the extension direction of the furring strips M5 but also the position of the guide member 10 in the width direction of the furring strips M5. In this embodiment, since the base portion 20 has the attachment portion 23, it is only necessary to adjust the position of the guide member 10 in the extension direction of the furring strips M5. This allows the guide member 10 to be easily installed at an appropriate position on the wall surface Ws.

[0053] In the installation step according to this embodiment, the guide member 10 is installed on the wall surface Ws with the opening 44 and the notch 22 continuous with the opening 44 facing upward. This allows the guide member 10 to be easily removed from the fastening member S by simply pulling the guide member 10 downward (in the direction of gravity) after a certain amount of the fastening member S has been driven in. Furthermore, the guide method according to this embodiment includes, before the installation step, a change step of changing the position of the wall surface Ws by increasing at least one of the exterior material and the insulating material (insulating material M4 in this embodiment) on the far side of the wall surface Ws. In the guide method according to this embodiment, even if the length of the shank Sx of the fastening member S becomes longer by changing the position of the wall surface Ws, the retaining portion 30 is engaged with the outer periphery of the shank Sx, so that the fastening member S can be driven perpendicularly into the wall surface Ws.

[0054] <<Other embodiments>> In the above embodiment, the base portion 20 protrudes upward beyond the holding portion 30, as shown in FIG. 3. In other words, the holding portion 30 is located below the upper end of the base portion 20. However, this is not limited thereto, and for example, as in the guide member 10A shown in FIG. 5, the holding portion 30A may extend to the same position as the upper end of the base portion 20A, and the upper ends of the holding portion 30A and the base portion 20A may be located at the same position. Alternatively, although not specifically shown, the holding portion 30A may extend upward beyond the upper end of the base portion 20A. 5, the guide member 10A has an extending portion 32A, which is composed of a first extending portion 34A and a second extending portion 35A that are spaced apart from each other in the second direction. The first extending portion 34A extends linearly from one end of the extending direction of the holding main body 31 (the direction along the imaginary circle C) to the upper end of the base 20A, and the second extending portion 35A extends linearly from the other end of the extending direction of the holding main body 31 to the upper end of the base 20A.

[0055] In this way, by having the holding portion 30A extend to the same position as the upper end of the base portion 20A or extend higher than the upper end of the base portion 20A, the installation area of ​​the holding portion 30A on the wall surface Ws can be increased compared to the holding portion 30 of the above embodiment. Note that the "installation area" refers to the area of ​​the range occupied by the holding portion 30A when viewed from the first direction. Therefore, even if the holding portion 30A receives a force that tends to topple the fastening member S sideways when the fastening member S is driven into the wall surface Ws, the installation area of ​​the holding portion 30A is ensured, so that the holding portion 30A can more appropriately resist the force. As a result, the fastening member S can be more appropriately held in a position perpendicular to the wall surface Ws.

[0056] Furthermore, by ensuring the installation area of ​​the retaining portion 30A, for example, it is possible to increase the degree of freedom in selecting the material for the retaining portion 30A. For example, if a material with lower hardness is selected as the material for the retaining portion 30A in order to make the opening 44 of the retaining portion 30A more easily elastically deformable, the rigidity of the retaining portion 30A may be reduced. In response to this, by ensuring the installation area of ​​the retaining portion 30A on the wall surface Ws, it is possible to more appropriately resist the lateral tipping force from the fastening member S, and as a result, it is possible to more appropriately hold the fastening member S in a position perpendicular to the wall surface Ws.

[0057] 3, the base portion 20 has the notch portion 22 above the holding portion 30 in the up-down direction. However, this is not limited to this, and for example, in a configuration such as a guide member 10A shown in FIG. 5 in which the base portion 20A does not protrude above the outer edge 43 of the holding portion 30A, the base portion 20A does not need to have a portion corresponding to the notch portion 22.

[0058] Furthermore, in the above embodiment, as shown in FIG. 2, the base portion 20 has a base main body portion 21, a cutout portion 22, and an attachment portion 23, but this is not limited to this. For example, as in the guide member 10B shown in FIG. 6, the base portion 20B may have only a base main body portion 21B and may not have portions corresponding to the cutout portion and the attachment portion. For example, a guide member 10B shown in FIG. 6 has two base main body portions 21B, and the two base main body portions 21B protrude outward beyond the outer edge 43 of the holding portion 30 in opposite directions in the second direction. This allows the user to press the two base main body portions 21B against the wall surface Ws with fingers, a tool, or the like, thereby appropriately holding the fastening member S in a position perpendicular to the wall surface Ws.

[0059] Furthermore, in the above embodiment, as shown in FIG. 3, when viewed from the first direction, the holding portion 30 is open in a portion of the entire range in the circumferential direction of the imaginary circle C (in this embodiment, the upper portion), and has an opening 44 as the open portion. However, this is not limited to this. For example, as shown in FIG. 7, the guide member 10C may have a cylindrical holding portion 30C, and the holding portion 30C may have an opening 44C that opens over a portion of the entire circumferential range of the holding portion 30C (the upper portion in the example shown in FIG. 7).

[0060] More specifically, the holding portion 30C has, for example, a cylindrical shape as shown in Fig. 7. However, without being limited to this, for example, the holding portion 30C may be configured as a tubular portion having a cross-sectional shape that is elliptical, rectangular, quadrilateral other than a rectangle, polygonal other than a quadrilateral, or irregular, etc. As shown in FIG. 7, the opening 44C extends continuously from one end 41C (the end opposite the base portion 20C) to the other end 42C (the end on the base portion 20 side) in the first direction (the extension direction of the holding portion 30C). More specifically, opening 44C has a first opening portion 45C, a second opening portion 46C, and a third opening portion 47C. First opening portion 45C, second opening portion 46C, and third opening portion 47C are arranged in the order of first opening portion 45C, third opening portion 47C, and second opening portion 46C in the first direction from one end 41C to the other end 42C, and adjacent opening portions are continuous with each other. Note that opening 44C is continuous with notch portion 22C provided in base portion 20C, and notch portion 22C is located above holding portion 30C in the up-down direction, as shown in FIG. 7 .

[0061] More specifically, the first opening 45C extends in the first direction toward the base 20C. The third opening 47C extends from the end of the first opening 45C on the base 20C side toward the base 20C, tilting relative to the first direction. The second opening 46C extends in the first direction from the end of the third opening 47C on the base 20C side toward the base 20C. In other words, the first opening 45C and the second opening 46C are located at different points in the circumferential direction of the cylindrical holder 30C when viewed from the first direction. The widths of the first opening 45C, the third opening 47C, and the second opening 46C are, for example, approximately the same and are smaller than the diameter of the shaft Sx. Note that the "width" here refers to the width in a direction perpendicular to the extension direction of each opening. Furthermore, in the above description, the third opening portion 47C is described as extending at an angle relative to the first direction, but this is not limited to this, and for example, it may extend in a direction perpendicular to the first direction, that is, the opening shape connected by the first opening portion 45C, the second opening portion 46C, and the third opening portion 47C may be crank-shaped.

[0062] As described above, in guide member 10C of this modified example, first opening portion 45C and second opening portion 46C are located at different points in the circumferential direction of cylindrical holding portion 30C when viewed from the first direction. Therefore, even if holding portion 30C receives a force that causes it to fall sideways from fastening member S, fastening member S will not easily come off holding portion 30C, and fastening member S can be properly held in a position perpendicular to wall surface Ws. On the other hand, after driving in a certain amount of the fastening member S, the guide member 10C can be easily removed from the fastening member S by tilting the guide member 10C relative to the fastening member S and pulling it downward. More specifically, by rotating the guide member 10C relative to the fastening member S, a portion of the shank Sx enters the second opening 46C. Furthermore, by rotating the guide member 10C, a portion of the shank Sx closer to the apex Sh than the portion of the shank Sx described above enters the third opening 47C. Furthermore, by rotating the guide member 10C, a portion of the shank Sx closer to the apex Sh than the portion closer to the apex Sh enters the first opening 45C, and when the width of the first opening 45C becomes equal to or greater than the diameter of the shank Sx, the holder 30C can be removed from the shank Sx.
