[0012] Hereinafter, embodiments of the scaffolding board fastener and the scaffolding board fastening method of the present disclosure will be described with reference to the attached drawings. Note that the scaffolding board fastener and the scaffolding board fastening method of the present disclosure are not limited to the configurations and methods described in the following embodiments.

[0013] (Embodiment) FIG. 1 is a schematic perspective view of a suspended scaffolding using a fixing device 2 according to an embodiment.

[0014] The suspended scaffolding shown in Fig. 1 comprises at least one scaffolding board 4 and two horizontal single pipes 6, 8. The scaffolding board 4 has an outer frame portion 10 and an upper surface portion 12, and the upper surface portion 12 is provided with a plurality of regularly arranged meshes 13. Each of the meshes 13 shown in Fig. 1 has a diamond shape in a plan view. The scaffolding board 4 having the meshes 13 is called a "mesh-like scaffolding board." The mesh-like scaffolding board 4 is, for example, expanded metal.

[0015] The fixture 2 is a member for fixing the scaffolding board 4 onto the horizontal single pipe 6. The fixture 2 of the present disclosure is particularly used by being inserted into one mesh 13 of the mesh-like scaffolding board 4.

[0016] 1, the scaffolding plank 4 is supported from below by a horizontal single pipe 6, which is in turn supported from below by another horizontal single pipe 8. The horizontal single pipe 6 and the horizontal single pipe 8 are arranged in directions perpendicular to each other (horizontal direction) in a plan view, and in this embodiment, each is a round metal pipe.

[0017] In the following, the horizontal direction in which the horizontal single pipe 6 extends is referred to as the X-axis direction, the horizontal direction in which the horizontal single pipe 8 extends is referred to as the Y-axis direction, and the direction perpendicular to both the X-axis direction and the Y-axis direction (vertical direction) is referred to as the Z-axis direction.

[0018] The scaffolding board 4 and the horizontal single pipe 6 are in contact with each other, and the horizontal single pipe 6 and the horizontal single pipe 8 are connected to each other by connecting members such as orthogonal clamps (not shown).

[0019] Next, the configuration of fixture 2 will be described with reference to FIGS.

[0020] Figures 2 and 3 are perspective views of the fastener 2, and Figures 4 and 5 are side views of the fastener 2. Figures 2 and 4 both show the fastener 2 in an assembled state, and Figures 3 and 5 both show the fastener 2 in an exploded state.

[0021] As shown in FIGS. 2 to 5, fixture 2 includes a rod-shaped member 14 and a pressure plate 16. As shown in FIG.

[0022] The rod-shaped member 14 is an L-shaped member. The rod-shaped member 14 has a first portion 26 and a second portion 28 that extend in directions intersecting each other, and the first portion 26 and the second portion 28 form the L-shape.

[0023] In this embodiment, the first portion 26 and the second portion 28 extend in directions perpendicular to each other. In the position shown in Figures 2 to 5, the first portion 26 extends in the Z-axis direction, and the second portion 28 extends in the Y-axis direction.

[0024] With respect to both ends of the rod-shaped member 14, the tip side (+Z side) of the first portion 26 may be referred to as the "one end side," and the tip side (+Y side) of the second portion 28 may be referred to as the "other end side." One end may be referred to as the first end, and the other end may be referred to as the second end.

[0025] The rod-shaped member 14 further has a connection portion 29 at a location where the first portion 26 and the second portion 28 are connected. The connection portion 29 corresponds to a corner portion of the rod-shaped member 14. The connection portion 29 in this embodiment is gently curved.

[0026] The rod-shaped member 14 of this embodiment is integrally formed. The diameter of a cross section perpendicular to the length direction (axial direction) of the rod-shaped member 14 is constant in at least a portion / region including the first portion 26, the second portion 28, and the connection portion 29. The rod-shaped member 14 may be manufactured, for example, by bending a straight rod-shaped member.

[0027] A threaded portion 30 is provided at the tip of the first portion 26. The threaded portion 30 is a portion for screwing into the pressing plate 16, which will be described later, and has a threaded shape provided on the outer periphery.

[0028] The tip of the second portion 28 is provided with a recess 32 and a magnetic body 34 .

[0029] The recess 32 is a recess recessed in the Z-axis direction at the tip of the second portion 28, and is provided for disposing the magnetic body 34. The magnetic body 34 is a magnetic member (e.g., a magnet), and is inserted into the second portion 28 and fixed in the recess 32. The depth of the recess 32 is set to a depth that prevents the magnetic body 34 from protruding upward relative to other parts of the second portion 28. This makes it possible to configure the second portion 28 so that the magnetic body 34 does not hinder insertion when the second portion 28 is inserted into the mesh 13 of the scaffolding board 4.

[0030] The magnetic body 34 acts to attract the metal horizontal single pipe 6 when it approaches, and prevents the fixing device 2 from rotating in an unintended direction after the fixing device 2 is installed. The magnetic body 34 has an attitude maintaining function that maintains the attitude of the fixing device 2.

[0031] The pressure plate 16 is a plate-like member for pressing and fixing the scaffolding plate 4 shown in Fig. 1. The pressure plate 16 of this embodiment is composed of a circular plate with multiple through holes formed therein. The pressure plate 16 has multiple through holes 20, 22A, and 22B formed therein, which penetrate the pressure plate 16 in the thickness direction.

[0032] The through hole 20 is a hole for screwing in the threaded portion 30 of the rod-shaped member 14, and has an inner circumferential surface provided with a thread shape corresponding to the threaded portion 30. The through hole 20 functions as a screw receiving portion that receives the threaded portion 30.

[0033] The through holes 22A and 22B are holes for engaging with a first jig 36 (FIG. 6) described later. The through holes 22A and 22B each have a cross-sectional shape in a plan view that is different from a circle, and in this embodiment, is a D-shape.

[0034] When the pressing plate 16 is screwed into the rod-shaped member 14, it can rotate about a rotation axis Ax1 that corresponds to the axial direction (Z-axis direction) of the threaded portion 30 of the rod-shaped member 14. When the pressing plate 16 rotates about the rotation axis Ax1 while maintaining the posture of the rod-shaped member 14, the pressing plate 16 or the rod-shaped member 14 moves relatively up and down in the Z-axis direction (arrow Z1 in FIGS. 2 and 4).

[0035] In the assembled state shown in Figures 2 and 4, the press plate 16 and the second portion 28 of the rod-shaped member 14 form a space in which the scaffolding board 4 and the horizontal single pipe 6 shown in Figure 1 can be arranged so as to sandwich them from above and below. As shown in Figure 4, the lower surface of the press plate 16 and the upper surface of the second portion 28 of the rod-shaped member 14 face each other at a distance D1 (Figure 4) along the Z-axis direction, and the distance D1 changes when the press plate 16 is rotated. By rotating the press plate 16 in a direction that reduces the distance D1, the press plate 16 and the second portion 28 of the rod-shaped member 14 can sandwich and fix the scaffolding board 4 and the horizontal single pipe 6 from above and below.

[0036] In the fastener 2 having the above configuration, the dimension of the cross section perpendicular to the longitudinal direction (axial direction) of the rod-shaped member 14 is smaller than the dimension of one mesh 13 of the mesh-like scaffolding board 4 shown in Fig. 1. This allows the second part 28 of the rod-shaped member 14 to be inserted into the mesh 13 for use. It is not limited to the case of using the gap between two scaffolding boards as in the past, but it is possible to install the fastener 2 at any position on the top surface 12 of the scaffolding board 4, thereby improving the convenience and workability of the worker.

[0037] In this embodiment, the diameter of the rod-shaped member 14 is set to, for example, 13 mm.

[0038] FIG. 6 is a perspective view showing the first jig 36. As shown in FIG.

[0039] The first jig is a jig for rotating the pressing plate 16. The first jig has protrusions 40A and 40B, an engagement portion , and a hole .

[0040] The protruding portions 40A and 40B are portions to be inserted into the through holes 22A and 22B of the pressing plate 16, and have a cross-sectional shape (D-shape) corresponding to the through holes 22A and 22B.

[0041] The engaging portion 42 is a portion for engaging a tool such as an impact wrench, and protrudes in the opposite direction to the protruding portions 40A and 40B. The engaging portion 42 shown in Fig. 6 has a hexagonal cross-sectional outer shape.

[0042] The hole 44 is a hole for accommodating the screw portion 30 of the rod-shaped member 14 protruding from the through hole 20 of the pressure plate 16. The hole 44 in this embodiment is a through hole that extends to the upper end of the engagement portion 42.

[0043] When an operator uses the first jig 36, the operator inserts the protrusions 40A, 40B of the first jig 36 into the through holes 22A, 22B of the presser plate 16, engages the engagement portion 42 of the first jig 36 with a tool such as an impact wrench, and rotates the first jig 36 about the rotation axis Ax2. This allows the presser plate 16 engaged with the first jig 36 to rotate integrally.

[0044] FIG. 7 is a perspective view showing the second jig 46. As shown in FIG.

[0045] The second jig 46 is a jig for assisting the operation of rotating the pressing plate 16 using the first jig 36. The second jig 46 includes a handle portion 48, a connecting portion 50, and a tip portion 52.

[0046] The handle portion 48 is a portion with which an operator holds the second jig 46. The connection portion 50 is a portion that connects the handle portion 48 and the tip portion 52. The tip portion 52 is a portion that is located at the end opposite the handle portion 48.

[0047] Tip portion 52 is an end portion for engaging with rod-shaped member 14 of fixing device 2 to maintain the rotational posture of rod-shaped member 14. Tip portion 52 in this embodiment has a bifurcated shape to form recess 53. By arranging second portion 28 of rod-shaped member 14 in recess 53, the rotational posture of rod-shaped member 14 can be maintained.

[0048] With respect to the dimensions of a cross section perpendicular to the length direction of the second jig 46 (i.e., the direction in which the connection part 50 extends), the dimensions of the tip part 52 and the connection part 50 are set to be smaller than the dimensions of one mesh 13 of the scaffolding board 4 shown in Fig. 1. This allows the tip part 52 and the connection part 50 of the second jig 46 to be inserted into the mesh 13 for use.

[0049] A method for fixing mesh-like scaffolding board 4 onto horizontal single pipes 6 using fixture 2, first jig 36 and second jig 46 having the above-mentioned configuration will be described with reference to Figs. 8A to 8F.

[0050] 8A to 8F are schematic side views illustrating a method of using fixture 2 according to an embodiment.

[0051] 8A, a worker first holds the fixture 2 in a state in which the rod-shaped member 14 and the pressure plate 16 are connected, and inserts the second portion 28, which is the other end of the fixture 2, into one mesh 13 of the scaffolding board 4 (arrow A1). As described above, the dimension of the cross section perpendicular to the longitudinal direction of the rod-shaped member 14 including the second portion 28 is smaller than the dimension of one mesh 13, so that it can be inserted into the mesh 13.

[0052] The rod-shaped member 14 is inserted into the mesh 13 so as not to interfere with the horizontal single pipe 6 that supports the scaffolding board 4 from below. Specifically, the rod-shaped member 14 is inserted into the mesh 13 at a position shifted in the Y-axis direction relative to the horizontal single pipe 6 extending in the X-axis direction, and the rod-shaped member 14 is moved parallel to the XZ plane.

[0053] After inserting the rod-shaped member 14 into the mesh 13, the pressure plate 16 of the fixing device 2 is placed on the upper surface 12 of the scaffolding board 4, as shown in Fig. 8B. In the state shown in Fig. 8B, the worker manually rotates the pressure plate 16 to rotate the rod-shaped member 14 screwed to the pressure plate 16 (arrow R1). As a result, the second portion 28 of the rod-shaped member 14 is positioned directly below the horizontal single pipe 6.

[0054] As shown in FIG. 8C, by previously ensuring a relatively long distance between the pressure plate 16 and the second portion 28 of the rod-shaped member 14, the second portion 28 of the rod-shaped member 14 is disposed below the horizontal single pipe 6.

[0055] From the state shown in FIG. 8C, the worker rotates the pressing plate 16 using the first jig 36 and the second jig 46. Specifically, as shown in FIG. 8D, the worker holds the first jig 36 and inserts the protruding parts 40A and 40B of the first jig 36 into the through holes 22A and 22B of the pressing plate 16 (arrow A2). The worker further holds the second jig 46 and inserts the tip part 52 of the second jig 46 into the mesh 13 of the scaffolding board 4 (arrow A3). As described above, the dimension of the cross section perpendicular to the length direction of the tip part 52 and the connection part 50 of the second jig 46 is smaller than the dimension of one mesh 13, so that the second jig 46 can be inserted into the mesh 13.

[0056] 8E, the tip portion 52 of the second jig 46 is engaged with the second portion 28 of the rod-shaped member 14. More specifically, by arranging the second portion 28 in the recess 53 of the tip portion 52, the movement of the second portion 28 in the X-axis direction is restricted, thereby maintaining the rotational posture of the rod-shaped member 14. If necessary, the second portion 28 of the rod-shaped member 14 may be pressed downward (arrow A4).

[0057] With the rod-shaped member 14 held down by the second jig 46, the worker holds a tool such as an impact wrench in his other hand and engages the tool with the engagement portion 42 of the first jig 36 engaged with the presser plate 16. In this state, the worker operates the tool to rotate the first jig 36 and the presser plate 16 integrally about the rotation axes Ax1 and Ax2. Since the rotational position of the rod-shaped member 14 is maintained by the second jig 46, the rod-shaped member 14 moves up and down relatively in accordance with the rotation of the presser plate 16. By rotating the presser plate 16 in a direction in which the rod-shaped member 14 rises relatively (arrow A5), the second portion 28 of the rod-shaped member 14 comes into contact with the horizontal single pipe 6.

[0058] 8F, the second portion 28 of the rod-shaped member 14 comes into contact with the bottom of the horizontal single pipe 6, and the scaffolding board 4 and the horizontal single pipe 6 are sandwiched between the rod-shaped member 14 and the pressure plate 16 from above and below (arrow F). By applying a rotational force of the tool even after the contact, the scaffolding board 4 and the horizontal single pipe 6 can be firmly sandwiched and fixed to each other, and the scaffolding board 4 can be fixed onto the horizontal single pipe 6.

[0059] In the installed state shown in Fig. 8F, if the rotational force of the tool is insufficient, the rod-shaped member 14 may attempt to rotate in an unintended direction, i.e., in a direction away from directly below the horizontal single pipe 6. In response to this, the magnetic body 34 is provided at the tip of the second portion 28 of the rod-shaped member 14, and the magnetic body 34 is attracted to the metal horizontal single pipe 6, thereby suppressing further rotation of the fixing device 2. This allows the fixing device 2 to function in maintaining its posture.

[0060] When the second jig 46 shown in FIG. 8E is made of metal, it is further possible to firmly engage the tip portion 52 with the magnetic body 34 by bringing the tip portion 52 close to the magnetic body 34 when engaging the tip portion 52 of the second jig 46 with the second portion 28 of the rod-shaped member 14.

[0061] The fastener 2 having the above configuration is not limited to being installed in the gap between two scaffolding boards as with conventional fasteners, but can be installed using the entire upper surface 12 of the mesh-like scaffolding board 4, thereby improving the convenience and workability when installing the fastener 2.

[0062] As described above, the fixing device 2 of this embodiment is a fixing device for fixing a mesh-like scaffolding board 4 onto a horizontal single pipe 6 (single pipe), and comprises an L-shaped rod-shaped member 14 having a screw portion 30 at one end, and a pressure plate 16 having a through hole 20 (screw receiving portion) for screwing into the screw portion 30. By rotating the pressure plate 16 with the screw portion 30 screwed into the through hole 20, the relative positions of the rod-shaped member 14 and the pressure plate 16 can be adjusted, and the cross-sectional dimension perpendicular to the longitudinal direction of the rod-shaped member 14 is smaller than the dimension of one mesh 13 of the scaffolding board 4.

[0063] According to this configuration, the second portion 28 of the rod-shaped member 14 is inserted into one mesh 13 of the scaffolding board 4, and the horizontal single pipe 6 and the scaffolding board 4 are placed between the rod-shaped member 14 and the pressure plate 16, and the pressure plate 16 is then rotated, so that the horizontal single pipe 6 and the scaffolding board 4 are sandwiched and fixed from above and below. This improves the workability when fixing the scaffolding board 4.

[0064] Furthermore, in the fixing device 2 of this embodiment, the rod-shaped member 14 has a magnetic body 34 on the other end side. With this configuration, when the rod-shaped member 14 tries to rotate in an unintended direction after the fixing device 2 is installed, the magnetic body 34 sticks to the metal horizontal single pipe 6, thereby preventing the rod-shaped member 14 from further rotating, and the posture of the fixing device 2 can be easily maintained.

[0065] Furthermore, in the fixture 2 of this embodiment, the pressing plate 16 is rotatable by using the first jig . According to this configuration, the pressing plate 16 can be rotated by using the first jig .

[0066] Furthermore, in the fixture 2 of this embodiment, the pressure plate 16 has through holes 22A, 22B (holes) having a non-circular cross-sectional shape, and the first jig 36 has protrusions 40A, 40B having a cross-sectional shape corresponding to the through holes 22A, 22B. According to this configuration, by rotating the first jig 36 with the protrusions 40A, 40B of the first jig 36 inserted into the through holes 22A, 22B of the pressure plate 16, the pressure plate 16 can be rotated.

[0067] Furthermore, in the fixing device 2 of this embodiment, the second portion 28 (the portion on the other end side) of the rod-shaped member 14 inserted into the mesh 13 of the scaffolding board 4 can maintain its rotational posture by the second jig 46, and the cross-sectional dimension of the tip portion 52 of the second jig 46 is smaller than the dimension of one mesh 13 of the scaffolding board 4. According to this configuration, by inserting the tip portion 52 of the second jig 46 into the mesh 13 and rotating the pressing plate 16 while pressing down the second portion 28 of the rod-shaped member 14 from above, the posture of the rod-shaped member 14 when it relatively rises with the rotation of the pressing plate 16 can be stabilized.

[0068] In the fixing device 2 of the present embodiment, the tip portion 52 of the second jig 46 has a bifurcated shape. With such a configuration, the tip portion 52 of the second jig 46 pinches the second portion 28 of the rod-shaped member 14, thereby making it possible to maintain the rotational posture of the rod-shaped member 14.

[0069] In addition, the method of fixing the scaffolding board 4 in this embodiment includes the steps of inserting the second part 28 (the part on the other end side) of the rod-shaped member 14 in the fixing device 2 into one mesh 13 of the scaffolding board 4, adjusting the posture of the fixing device 2 so that the second part 28 of the rod-shaped member 14 is positioned below the horizontal single pipe 6, and rotating the pressure plate 16 arranged on the upper surface 12 of the scaffolding board 4 relative to the rod-shaped member 14 to relatively raise the rod-shaped member 14 screwed to the pressure plate 16, thereby bringing the second part 28 of the rod-shaped member 14 into contact with the horizontal single pipe 6.

[0070] According to such a method, the workability when fixing the scaffolding board 4 can be improved.

[0071] In addition, the method of fixing the scaffolding board 4 in this embodiment includes the steps of inserting the second part 28 (the part on the other end side) of the rod-shaped member 14 in the fixing device 2 into one of the meshes 13 of the scaffolding board 4, adjusting the posture of the fixing device 2 so that the second part 28 of the rod-shaped member 14 is positioned below the horizontal single pipe 6, inserting the tip part 52 of the second jig 46 into one of the meshes 13 of the scaffolding board 4 and engaging the tip part 52 with the second part 28 of the rod-shaped member 14, and rotating the pressure plate 16 arranged on the upper surface 12 of the scaffolding board 4 relative to the rod-shaped member 14 while maintaining the rotational posture of the rod-shaped member 14 with the second jig 46, thereby relatively raising the rod-shaped member 14 screwed to the pressure plate 16, thereby bringing the second part 28 of the rod-shaped member 14 into contact with the horizontal single pipe 6.

[0072] According to this method, by rotating the pressure plate 16 while maintaining the rotational position of the rod-shaped member 14, the operation of relatively lifting the rod-shaped member 14 can be easily and reliably achieved.

[0073] Although the present disclosure has been described above with reference to the above-mentioned embodiment, the present disclosure is not limited to the above-mentioned embodiment. For example, in the embodiment, the case where the connecting portion 29 constituting the L-shape of the rod-shaped member 14 is gently curved has been described, but the present disclosure is not limited to such a case. The connecting portion (corner portion) may have any shape, such as an angular shape, as long as it connects the first portion 26 and the second portion 28 and has a cross-sectional dimension that allows the mesh 13 to pass through.

[0074] In the embodiment, the first portion 26 and the second portion 28 of the rod-shaped member 14 extend in directions perpendicular to each other. However, the present invention is not limited to this case, and the first portion 26 and the second portion 28 may not extend perpendicular to each other.

[0075] The present disclosure is applicable to any fastener for fixing a mesh-like scaffolding board onto a single pipe and a method for fixing the scaffolding board using the same.

[0076] Any of the above-described various embodiments and modified examples can be appropriately combined to achieve the effects of each of them.

[0077] Although the present disclosure has been fully described in connection with the preferred embodiment with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art, and such changes and modifications should be understood to be included within the scope of the present invention as defined by the appended claims, unless they depart therefrom.
