Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the scaffold board fixture and the scaffold board fixing method of the present disclosure will be described with reference to the accompanying drawings. Note that the scaffold board fixture and the scaffold board fixing 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 scaffold using the fixture 2 according to the embodiment.

[0014] The suspended scaffold shown in FIG. 1 includes at least one scaffold board 4 and two horizontal single pipes 6 and 8. The scaffold board 4 has an outer frame portion 10 and an upper surface portion 12, and a plurality of regularly arranged meshes 13 are provided on the upper surface portion 12. Each of the meshes 13 shown in FIG. 1 has a rhombus shape in plan view. The scaffold board 4 having the meshes 13 is referred to as a "meshed scaffold board". The meshed scaffold board 4 is, for example, expanded metal.

[0015] The fixture 2 is a member for fixing the scaffold board 4 on the horizontal single pipe 6. In particular, the fixture 2 of the present disclosure is inserted into one mesh 13 of the meshed scaffold board 4 and used.

[0016] As shown in FIG. 1, the scaffolding board 4 is supported from below by the horizontal single pipe 6, and the horizontal single pipe 6 is supported from below by another horizontal single pipe 8. The horizontal single pipe 6 and the horizontal single pipe 8 are arranged in directions (horizontal directions) perpendicular to each other in plan view, and in this embodiment, they are round pipes made of metal respectively.

[0017] Hereinafter, the horizontal direction in which the horizontal single pipe 6 extends is defined as the X-axis direction, the horizontal direction in which the horizontal single pipe 8 extends is defined as the Y-axis direction, and the direction (vertical direction) perpendicular to both the X-axis direction and the Y-axis direction is defined 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 a connecting member such as an orthogonal clamp (not shown).

[0019] Next, the configuration of the fixture 2 will be described with reference to FIGS. 2 to 5.

[0020] FIGS. 2 and 3 are perspective views of the fixture 2, and FIGS. 4 and 5 are side views of the fixture 2. Both FIGS. 2 and 4 show the assembled state of the fixture 2, and both FIGS. 3 and 5 show the disassembled state of the fixture 2.

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

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

[0023] In this embodiment, the first portion 26 and the second portion 28 extend in directions perpendicular to each other. In the posture shown in FIGS. 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] Regarding 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 connecting portion 29 at a location connecting the first portion 26 and the second portion 28. The connecting portion 29 corresponds to a corner portion of the rod-shaped member 14. The connecting portion 29 of the present embodiment is gently curved.

[0026] The rod-shaped member 14 of the present embodiment is integrally formed. The rod-shaped member 14 has a constant diameter of a cross-section orthogonal to the length direction (axial direction) in at least the portion / region including the first portion 26, the second portion 28, and the connecting portion 29. When manufacturing the rod-shaped member 14, for example, a straight rod-shaped member may be bent for manufacturing.

[0027] A screw portion 30 is provided at the tip of the first portion 26. The screw portion 30 is a portion for screwing into a pressing plate 16 described later, and a screw shape is provided on the outer peripheral portion.

[0028] A concave portion 32 and a magnetic body 34 are provided at the tip of the second portion 28.

[0029] The concave portion 32 is a concave portion recessed in the Z-axis direction at the tip of the second portion 28, and is provided for arranging the magnetic body 34. The magnetic body 34 is a member having magnetism (for example, a magnet), and is inserted and fixed to the second portion 28 in the concave portion 32. The depth of the concave portion 32 is set to a depth such that the magnetic body 34 does not protrude upward with respect to other portions of the second portion 28. Thereby, when inserting the second portion 28 into the mesh 13 of the scaffold plate 4, the magnetic body 34 can be configured not to hinder the insertion.

[0030] The magnetic body 34 acts to be attracted when approaching the metal horizontal single tube 6, and suppresses the fixture 2 from rotating in an unintended direction after the fixture 2 is installed. The magnetic body 34 has a posture maintaining function for maintaining the posture of the fixture 2.

[0031] The pressing plate 16 is a plate-shaped member for pressing and fixing the scaffolding plate 4 shown in FIG. 1. The pressing plate 16 of the present embodiment is composed of a disk having a plurality of through holes formed therein. A plurality of through holes 20, 22A, and 22B penetrating in the thickness direction are formed in the pressing plate 16.

[0032] The through hole 20 is a hole for screwing the screw portion 30 of the rod-shaped member 14, and a screw shape corresponding to the screw portion 30 is provided on the inner peripheral surface. The through hole 20 functions as a screw receiving portion for receiving the screw portion 30.

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

[0034] The pressing plate 16 is rotatable about a rotation axis Ax1 corresponding to the axial direction (Z-axis direction) of the screw portion 30 of the rod-shaped member 14 in a state where it is screwed to 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 FIGS. 2 and 4, the pressing plate 16 and the second portion 28 of the rod-shaped member 14 form a space in which the scaffolding plate 4 and the horizontal single pipe 6 shown in FIG. 1 can be arranged so as to sandwich them vertically. As shown in FIG. 4, the lower surface portion of the pressing plate 16 and the upper surface portion of the second portion 28 of the rod-shaped member 14 face each other at a distance D1 (FIG. 4) along the Z-axis direction, and when the pressing plate 16 is rotated, the distance D1 changes. By rotating the pressing plate 16 in a direction to reduce the distance D1, the scaffolding plate 4 and the horizontal single pipe 6 can be sandwiched and fixed vertically by the pressing plate 16 and the second portion 28 of the rod-shaped member 14.

[0036] In the fixture 2 having the above configuration, the dimension of the cross section orthogonal to the length direction (axial direction) of the rod-shaped member 14 is smaller than the dimension of one mesh 13 of the mesh-shaped scaffold plate 4 shown in FIG. 1. Thereby, the second portion 28 of the rod-shaped member 14 can be inserted into the mesh 13 and used. Not limited to the case of using the gap between two scaffold plates as in the prior art, the fixture 2 can be installed at an arbitrary position on the upper surface portion 12 of the scaffold plate 4, improving the convenience and workability of the operator.

[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.

[0039] The first jig 36 is a jig for rotating the pressing plate 16. The first jig 36 has protruding portions 40A, 40B, an engaging portion 42, and a hole portion 44.

[0040] The protruding portions 40A and 40B are portions 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 direction opposite 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 portion 44 is a hole portion for accommodating the threaded portion 30 of the rod-shaped member 14 protruding from the through hole 20 of the pressing plate 16. The hole portion 44 of this embodiment is a through hole extending to the upper end of the engaging portion 42.

[0043] When the operator uses the first jig 36, with the protruding portions 40A and 40B of the first jig 36 inserted into the through holes 22A and 22B of the pressing plate 16, a tool such as an impact wrench is engaged with the engaging portion 42 of the first jig 36, and the first jig 36 is rotated about the rotation axis Ax2. Thereby, the pressing plate 16 engaged with the first jig 36 can be integrally rotated.

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

[0045] The second jig 46 is a jig for assisting the operation when 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 for an operator to hold the second jig 46. The connecting portion 50 is a portion connecting the handle portion 48 and the tip portion 52. The tip portion 52 is a portion located at the end opposite to the handle portion 48.

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

[0048] Regarding the dimensions of the cross section orthogonal to the longitudinal direction of the second jig 46 (i.e., the direction in which the connecting portion 50 extends), the dimensions of the tip portion 52 and the connecting portion 50 are set to be smaller than the dimensions of one mesh 13 of the scaffold board 4 shown in FIG. 1. Thereby, the tip portion 52 and the connecting portion 50 of the second jig 46 can be inserted into the mesh 13 for use.

[0049] A method of fixing the mesh-shaped scaffold board 4 onto the horizontal single pipe 6 using the fixture 2, the first jig 36, and the second jig 46 having the above-described configuration will be described with reference to FIGS. 8A to 8F.

[0050] FIGS. 8A to 8F are schematic side views for explaining the usage method of the fixture 2 according to the embodiment.

[0051] As shown in Fig. 8A, first, the operator holds the fixture 2 with the rod-shaped member 14 and the pressing plate 16 connected, and inserts the second part 28, which is the other end side part of the fixture 2, into one mesh 13 of the scaffold plate 4 (arrow A1). As described above, since the dimension of the cross-section orthogonal to the length direction of the rod-shaped member 14 including the second part 28 is smaller than the dimension of one mesh 13, it can be inserted into the mesh 13.

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

[0053] After inserting the rod-shaped member 14 into the mesh 13, as shown in Fig. 8B, the pressing plate 16 of the fixture 2 is placed on the upper surface part 12 of the scaffold plate 4. In the state shown in Fig. 8B, the operator rotates the pressing plate 16 manually to rotate the rod-shaped member 14 screwed to the pressing plate 16 (arrow R1). Thereby, the second part 28 of the rod-shaped member 14 is arranged directly below the horizontal single pipe 6.

[0054] As shown in Fig. 8C, by securing a relatively long distance in advance between the pressing plate 16 and the second part 28 of the rod-shaped member 14, the second part 28 of the rod-shaped member 14 is arranged below the horizontal single pipe 6.

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

[0056] As shown in FIG. 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 disposing the second portion 28 in the concave portion 53 of the tip portion 52, the movement of the second portion 28 in the X-axis direction is restricted to maintain 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 by the second jig 46, the operator holds a tool such as an impact wrench in the other hand and engages the tool with the engaging portion 42 of the first jig 36 engaged with the pressing plate 16. In that state, the tool is operated to integrally rotate the first jig 36 and the pressing plate 16 about the rotation axes Ax1 and Ax2. Since the rotational posture of the rod-shaped member 14 is maintained by the second jig 46, the rod-shaped member 14 moves relatively up and down as the pressing plate 16 rotates. By rotating the pressing plate 16 in the direction in which the rod-shaped member 14 relatively rises (arrow A5), the second portion 28 of the rod-shaped member 14 contacts the horizontal single pipe 6.

[0058] As shown in FIG. 8F, the second portion 28 of the rod-shaped member 14 contacts the bottom of the horizontal single pipe 6, and the scaffolding plate 4 and the horizontal single pipe 6 are clamped up and down by the rod-shaped member 14 and the pressing plate 16 (arrow F). By applying the rotational force of the tool even after the contact, the scaffolding plate 4 and the horizontal single pipe 6 can be firmly clamped and fixed to each other, and the scaffolding plate 4 can be fixed on the horizontal single pipe 6.

[0059] In the installed state shown in FIG. 8F, when the rotational force of the tool is insufficient or the like, the rod-shaped member 14 may try to rotate in an unintended direction, that is, a direction deviating from directly below the horizontal single pipe 6. In contrast, since the magnetic body 34 is provided at the tip of the second portion 28 of the rod-shaped member 14, the magnetic body 34 is attracted to the metal horizontal single pipe 6, thereby suppressing further rotation of the fixture 2. Thereby, the function of maintaining the posture of the fixture 2 can be exhibited.

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

[0061] According to the fixture 2 having the above configuration, it is not limited to the usage form of being installed in the gap between two scaffolding plates like the conventional fixture, and it can be installed using the entire upper surface portion 12 of the mesh-shaped scaffolding plate 4, improving the convenience and workability when installing the fixture 2.

[0062] As described above, the fixture 2 of the present embodiment is a fixture for fixing the mesh-shaped scaffolding plate 4 on the horizontal single pipe 6 (single pipe), and includes a rod-shaped member 14 having an L shape and a screw portion 30 at one end side, and a pressing plate 16 having a through hole 20 (screw receiving portion) for screwing the screw portion 30. By rotating the pressing plate 16 in a state where the screw portion 30 is screwed into the through hole 20, the relative position between the rod-shaped member 14 and the pressing plate 16 can be adjusted, and the dimension of the cross section orthogonal to the length direction of the rod-shaped member 14 is smaller than the dimension of one mesh 13 of the scaffolding plate 4.

[0063] According to such a configuration, by inserting the second portion 28 of the rod-shaped member 14 into one mesh 13 of the scaffolding plate 4 and rotating the pressing plate 16 with the horizontal single pipe 6 and the scaffolding plate 4 arranged between the rod-shaped member 14 and the pressing plate 16, the horizontal single pipe 6 and the scaffolding plate 4 can be clamped and fixed vertically. Thereby, the workability when fixing the scaffolding plate 4 can be improved.

[0064] In addition, in the fixture 2 of the present embodiment, the rod-shaped member 14 has a magnetic body 34 on the other end side. According to such a configuration, when the rod-shaped member 14 tries to rotate in an unintended direction after the fixture 2 is installed, the magnetic body 34 can be attracted to the metal horizontal single pipe 6 to suppress further rotation of the rod-shaped member 14, making it easier to maintain the posture of the fixture 2.

[0065] Also, in the fixture 2 of the present embodiment, the pressing plate 16 is rotatable using the first jig 36. According to such a configuration, the pressing plate 16 can be rotated using the first jig 36.

[0066] Also, in the fixture 2 of the present embodiment, the pressing plate 16 has non-circular through-holes 22A and 22B (hole portions) in cross-sectional shape, and the first jig 36 has protruding portions 40A and 40B with a cross-sectional shape corresponding to the through-holes 22A and 22B. According to such a configuration, if the first jig 36 is rotated with the protruding portions 40A and 40B of the first jig 36 inserted into the through-holes 22A and 22B of the pressing plate 16, the pressing plate 16 can be rotated.

[0067] Also, in the fixture 2 of the present 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 scaffold plate 4 can have its rotational posture maintained by the second jig 46, and the dimension of the cross-section of the tip portion 52 of the second jig 46 is smaller than the dimension of one mesh 13 of the scaffold plate 4. According to such a configuration, by rotating the pressing plate 16 with the tip portion 52 of the second jig 46 inserted into the mesh 13 and pressing the second portion 28 of the rod-shaped member 14 from above, the posture of the rod-shaped member 14 when the rod-shaped member 14 relatively rises as the pressing plate 16 rotates can be stabilized.

[0068] Also, in the fixture 2 of the present embodiment, the tip portion 52 of the second jig 46 has a bifurcated shape. According to such a configuration, the rotational posture of the rod-shaped member 14 can be maintained by sandwiching the second portion 28 of the rod-shaped member 14 with the tip portion 52 of the second jig 46.

[0069] Also, in the method for fixing the scaffolding board 4 of the present embodiment, it includes the steps of inserting the second portion 28 (the portion on the other end side) of the rod-shaped member 14 in the fixture 2 into one mesh 13 of the scaffolding board 4, adjusting the posture of the fixture 2 so that the second portion 28 of the rod-shaped member 14 is disposed below the horizontal single pipe 6, and rotating the pressing plate 16 disposed on the upper surface portion 12 of the scaffolding board 4 with respect to the rod-shaped member 14 and relatively raising the rod-shaped member 14 screwed to the pressing plate 16 to bring the second portion 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] Also, in the method for fixing the scaffolding board 4 of the present embodiment, it includes the steps of inserting the second portion 28 (the portion on the other end side) of the rod-shaped member 14 in the fixture 2 into one mesh 13 of the scaffolding board 4, adjusting the posture of the fixture 2 so that the second portion 28 of the rod-shaped member 14 is disposed below the horizontal single pipe 6, inserting the tip portion 52 of the second jig 46 into one mesh 13 of the scaffolding board 4 and engaging the tip portion 52 with the second portion 28 of the rod-shaped member 14, and rotating the pressing plate 16 disposed on the upper surface portion 12 of the scaffolding board 4 with respect to the rod-shaped member 14 in a state where the rotational posture of the rod-shaped member 14 is maintained by the second jig 46 and relatively raising the rod-shaped member 14 screwed to the pressing plate 16 to bring the second portion 28 of the rod-shaped member 14 into contact with the horizontal single pipe 6.

[0072] According to such a method, by rotating the pressing plate 16 while maintaining the rotational posture of the rod-shaped member 14, the operation of relatively raising the rod-shaped member 14 can be realized easily and more reliably.

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

[0074] In the embodiment, the case where the first portion 26 and the second portion 28 of the rod-shaped member 14 extend in a direction perpendicular to each other has been described, but it is not limited to such a case, and they may not be perpendicular.

[0075] The present disclosure is applicable to a fixture for fixing a mesh-shaped scaffold board on a single pipe and a method for fixing a scaffold board using the same.

[0076] Note that by appropriately combining any of the above-described various embodiments and modifications, the respective effects can be achieved.

[0077] The present disclosure is fully described in relation to preferred embodiments with reference to the accompanying drawings, but various variations and modifications will be apparent to those skilled in the art. Such variations and modifications should be understood to be included therein as long as they do not depart from the scope of the present invention as defined by the appended claims.
