One holding means for holding the circular cross-section member of the two holding means provided on the connecting member, even if the cross-section in the direction of the cross-section is circular. At least one of them is provided with a rotation preventing means for preventing one of the holding means from rotating about the circular cross-section member. Can be eliminated.

  Such a rotation preventing means may be of various forms, and one example of the rotation preventing means is an uneven fitting means for unevenly fitting the one holding means and the circular section member. Further, another example of the rotation preventing means is a friction contact means for bringing the one holding means into friction contact with the circular section member.

  If the rotation preventing means is the uneven fitting means, it is possible to more reliably prevent the one holding means from rotating about the circular cross section member.

  In order to make the rotation preventing means the above-mentioned uneven fitting means, for example, one of the one holding means and the circular cross-section member is provided with a convex portion, and the other is fitted with the convex portion. This can be realized by providing concave portions that match each other, and each of these convex portions and concave portions may be one, or may be, for example, a plurality of each provided in the circumferential direction of the circular cross-sectional member.

It is configured to include two clamping members, and at least one of the clamping members is provided with at least one of the convex portion and the concave portion constituting the concave-convex fitting means. One is provided, and the other of the convex portion and the concave portion is provided on the circular cross-sectional member.

  In addition, another example of the holding means includes a first member having a concave portion into which all or a part of the circular cross-sectional member is fitted, and an opening of the concave portion is disposed in the first member so as to be freely opened and closed, A second member for holding the circular cross-section member in cooperation with the first member by closing the opening of the depression.

  As described above, the holding means includes two holding members that hold the circular cross-sectional member by being held, and at least one holding member among these holding members is provided. In the case where one of the convex portion and the concave portion constituting the concave-convex means is provided, and the circular cross-sectional member is provided with the other of the convex portion and the concave portion, The two clamping members are members for clamping the circular cross-section member from above and below, and the upper clamping member is rotatable with respect to the lower clamping member, and the lower clamping member is It is also possible to provide the above-mentioned convex portion of the concave-convex fitting means serving as the above-mentioned rotation preventing means, and to form the concave portion of this concave-convex fitting means below the circular section member.

  When the holding means and the concave-convex fitting means are configured as described above, the convex portion is a pin fixed upward to the lower clamping member, and the concave portion is formed of a round pipe material. It is good also as a hole provided in the above-mentioned circular section member.

  According to this, it is possible to rationally provide the convex portion and the concave portion constituting the concave-convex fitting means on the holding member constituting the retaining means and the circular cross-section member, and to form the upper and lower two parts constituting the retaining means. When the circular section member is clamped by the clamping member, the pin serving as the convex portion can be easily inserted into the hole formed as the concave portion in the circular section member.

FIG. 1 shows a plurality of scaffold panels each suspended by a suspending member 5 such as a chain and arranged side by side in a horizontal direction and a horizontal direction and a front-rear direction to form a temporary suspended scaffold 6. It is shown. These scaffold panels include a first scaffold panel 1, a second scaffold panel 2, a third scaffold panel 3, and a fourth scaffold panel 4. FIG. 2 is an overall schematic plan view of the temporary suspension scaffold 6 formed by the scaffold panels 1 to 4 with the suspension member 5 omitted, and FIG. By removing the three fourth scaffold panels 4 from the temporary suspension scaffold 6, the opening 7 that can be used for passing articles such as building materials and equipment through the temporary suspension scaffold 6 is moved up and down. 2 is a plan view showing the entire structure in a state of being penetrated.

  FIG. 4 is a plan view of the first scaffold panel 1, and FIGS. 5 to 7 show plan views of the second to fourth scaffold panels 2 to 4. These first to fourth scaffold panels 1 to 4 are a plan view of a panel main body excluding a first connecting member 35 and a second connecting member 36 and a first connecting member 45 and a second connecting member 55 to be described later. The outer contour of the overall shape is a rectangular shape. More specifically, the outer contour of the overall shape of the panel body of these scaffold panels 1 to 4 in plan view is a scaffold panel. When the temporary suspending scaffold 6 of FIGS. 1 and 2 is formed by 1 to 4, the left-right direction of the temporary suspending scaffold 6 is the short side portion, and is the front-back direction of the temporary suspending scaffold 6. The directions are long sides, and the shapes of the panel bodies of the scaffold panels 1 to 4 are the same in plan view. For this reason, in the panel main bodies of the respective scaffold panels 1 to 4, the length of the short side in the outer contour portion of the overall shape in plan view is the same, and the length of the long side is also the same. The vertical dimension of the scaffold panels 1 to 4 is also the same.

  For this reason, the temporary suspension scaffold 6 formed by arranging these scaffold panels 1 to 4 side by side in the left and right direction and the front and rear direction matches the respective scaffold panels 1 to 4 in the left and right direction and the front and rear direction, It can also be formed in the vertical direction.

  Since the basic structures of the first to fourth scaffold panels 1 to 4 are the same, the common structure of the first to fourth scaffold panels 1 to 4 will be described next with reference to FIGS.

  The long sides of the first to fourth scaffold panels 1 to 4 are formed by long side members 11 and 12 made of two channel materials having opening sides facing inside (see also FIG. 9), and FIG. As shown in FIG. 7, a short side perpendicular to the long side is provided between both ends of the long side members 11 and 12 in the longitudinal direction or between the vicinity of both ends. The horizontal members 13 and 14 whose length directions are the directions of the respective length dimensions are bridged, and the connection between the long side members 11 and 12 and the horizontal members 13 and 14 is performed by the horizontal member 13. , 14 are joined by welding end members 15 joined to both ends in the length direction of the long side members 11 and 12 by welding. A bridging member 16 made of a round pipe material is bridged between these transverse members 13 and 14 in parallel with the long side members 11 and 12, and both ends of the bridging member 16 are connected to the transverse members 13 and 14. End members 17 are welded to the scaffolding panels 14, and the bridging members 16 and the end members 17 are arranged at the center in the length direction of the short sides of the scaffold panels 1 to 4. .

  Since each of the horizontal members 13 and 14 having a horizontal length at the short side is formed of two round pipe members having the same diameter, these horizontal members are used. Reference numerals 13 and 14 are circular cross-section members having a circular cross section in a direction orthogonal to the length direction.

  On the upper surfaces of the long side members 11 and 12 of each of the scaffold panels 1 to 4, a surface member 18 formed of a rectangular metal plate whose length is shorter than the long sides of the scaffold panels 1 to 4 is covered. Both ends in the length direction of the short side of the surface member 18 are connected to the upper surfaces of the long side members 11 and 12 by welding or screws, and both ends in the length direction of the long side of the surface member 18. The portion is a bar-like intermediate member 19 made of a channel material or the like fixedly arranged between the long side members 11 and 12 and the bridging member 16 on the inner side of the scaffold panels 1 to 4 than the horizontal members 13 and 14. They are connected by welding or screws. As a result, the upper surfaces of the scaffold panels 1 to 4 on which the surface members 18 are arranged are horizontal work surfaces on which an operator can perform work or the like while riding.

  A lid member 21 is attached to the intermediate member 19 by a hinge 20 so as to be openable and closable, and these lid members 21 disposed on both ends in the length direction of the long sides of the respective scaffold panels 1 to 4 are closed. Thereby, the openings at both ends in the longitudinal direction of the long sides of the scaffold panels 1 to 4 that are not covered by the surface member 18 are covered by the cover member 21 and covered these openings. The lid member 21 is supported from below by end members 17 provided at both ends of the bridging member 16, and a worker can ride on the lid member 21 to perform work or the like. By increasing the length of the short sides of the scaffold panels 1 to 4 in the length direction of the lid member 21, the lid member 21 is also closed by the upper surfaces of the long side members 11 and 12 when the lid member 21 is closed. You may make it supportable from a lower side.

  Inside the scaffold panels 1-4 exposed when the lid member 21 is opened, two holding members 22 on the long side member 11 side and two holding members 23 on the long side member 12 side are intermediate members. 19, these holding members 22 and 23, each of which is formed of a square pipe material, are arranged at the same position in the longitudinal direction of the long sides of the scaffold panels 1-4. A long nut 24 is vertically welded to the outer surface of each of them, and is joined by welding. Each of the lid members 21 has a hole 21A for exposing the long nut 24 when these lid members 21 are closed. Are formed. In addition, a long hole 18A for exposing the suspension ring member 25 connected to the bridging member 16 is formed in the surface member 18. Further, each lid member 21 is provided with a lock 26 for locking the lid member 21 when the lid member 21 is closed.

  This lock 26 is shown in FIG. The lock member 26 has a rotatable shaft member 29 penetrating through the lid member 21 and one end in the length direction connected to both ends of the shaft member 29 on both front and back sides of the lid member 21. And a plurality of clamping members 30 and 31. When the shaft member 29 is rotated by operating the holding member 30 disposed on the front side of the lid member 21, the two holding members 30, 31 also rotate, and these holding members 30, 31 By sandwiching upper flange portions 11A and 12A of the long side members 11 and 12 formed of the channel material from above and below, the lid member 21 closed with respect to the long side members 11 and 12 is locked. Is locked.

  Of the first to fourth scaffold panels 1 to 4 shown in FIGS. 1 to 3, two first scaffold panels 1A and one of the first scaffold panels 1A disposed between the first scaffold panels 1A. The third scaffold panel 3 is a starter panel that is suspended and first placed by the suspension member 5 when the temporary suspended scaffold 6 is formed. Into the long nut 24 exposed from the hole 21A of the closed lid member 21 in these starter panels, a male screw rod connected to a clamp 28 for holding a rod-shaped member 27 made of a pipe material is screwed. The hanging member 5 of FIG. 1 is hung around the rod-shaped member 27 attached to the starter panel by the clamp 28, so that the starter panel is hung at the installation site of the temporary hanging scaffold 6. Of the first to fourth scaffold panels 1 to 4 shown in FIGS. 1 to 3, the suspension is also applied to the suspension ring member 25 exposed from the long hole 18 </ b> A of the surface member 18 of the scaffold panel excluding the starter panel. The hanging member 5 is hung around, so that the scaffold panel except the starter panel is also hung at the installation site of the temporary hanging scaffold 6 to form the temporary hanging scaffold 6.

  As shown in FIG. 10, for each of the scaffold panels 1 to 4, the long side member 11 has a hole for exposing the end of the above-described holding member 22 formed of a square pipe material. 11B, and as shown in FIG. 11, the long side member 12 is also formed with a hole 12B for exposing the end of the holding member 23 formed of a square pipe material. .

  Next, a specific structure of each of the first to fourth scaffold panels 1 to 4 will be described.

  First, a specific structure of the first scaffold panel 1 shown in FIG. 4 will be described. In the first scaffold panel 1, two holding members 22 provided on one long side member 11 side are provided. The first connection member 35 is disposed at a position corresponding to each of the two connection members, and the second connection member is disposed at a position corresponding to each of the two holding members 23 provided on one long side member 12 side. 36 are arranged. For this reason, of the two long sides parallel to each other on the first scaffold panel 1, two first connection members 35 are provided on one long side and the other long side is provided. The portion is provided with two second connection members 36, and thus the first scaffold panel 1 is a scaffold panel with connection members. The arrangement of the first and second connection members 35 and 36 in the first scaffold panel 1 is such that the first and second connection members 35 and 36 are, as described above, the first and second connection members 35 and 36. Except for this, the first scaffold panel 1 is horizontally projected from the outer contour portion of the panel body to the outside in a plan view. Are fixed to the holding member 22 inside the holding member 22, and the base of the second connecting member 36 is fixed to the holding member 23 inside the holding member 23, and the first and second connecting members The distal ends of the first and second scaffold panels 35 and 36 project outside from the outer contour of the panel body of the first scaffold panel 1 whose overall shape in plan view is rectangular except for these connecting members 35 and 36.

  FIG. 10 is a front view of the first connection member 35 provided on the long side member 11 by fixing the base portion to the holding member 22 inside the holding member 22. FIG. As shown, the first connection member 35 has a V-shaped groove 35A that is open upward at the top. FIG. 11 is a front view of a second connecting member 36 provided on the long side member 12 by fixing the base portion to the holding member 23 inside the holding member 23. As shown in FIG. 11, the second connecting member 36 has a downwardly V-shaped protrusion 36A at the lower portion.

  Therefore, in order to form the temporary suspension scaffold 6 of FIGS. 1 to 3, the two first scaffold panels 1 suspended by the suspension members 5 of FIG. When these first scaffold panels 1 are juxtaposed in the left-right direction, which is the length direction of the short sides, the first scaffold panels 1 are provided on one of the first scaffold panels 1 as shown in FIG. The protrusion 36A of the second connection member 36 provided on the other first scaffold panel 1 is placed on the groove 35A of the connection member 35. Then, by bringing these first scaffold panels 1 closer to each other, the state in which the protrusion 36A of the second connection member 36 is placed on the groove 35A of the first connection member 35 is maintained, and the second connection member 36 The leading end is inserted into the one first scaffold panel 1, whereby the two first scaffold panels 1 are arranged adjacently in the left-right direction with little or no gap.

  Note that, as described above, the first and second connection members 35 and 36 provided on the first scaffold panel 1 of the present embodiment have an overall shape in plan view excluding these connection members 35 and 36 as described above. Since the first scaffold panel 1 has a rectangular shape and protrudes outward from the outer contour of the panel body, as described above, each of the first scaffold panels 1 is attached to the short side of the first scaffold panel 1. When performing the work of juxtaposition in the left-right direction that is the length direction, the second scaffold panel 1 is provided on the first connecting member 35 provided on the first scaffold panel 1. The connection member 36 can be placed. Accordingly, the weight of the other first scaffold panel 1 can be supported by the one first scaffold panel 1, and these first scaffold panels 1 are adjacent to each other in the left-right direction with little or no gap. The work for arrangement can be performed easily.

  FIG. 14 shows a connector for connecting the first scaffold panels 1 to each other after arranging the two first scaffold panels 1 adjacently in the left-right direction with no or almost no gap as described above. 37 is shown. As shown in FIG. 13, the connecting tools 37 are arranged at locations on the long side members 11 of the first scaffold panels 1 corresponding to the locations of the respective first connecting members 35. The connecting tool 37 will be described with reference to FIG. 14. The connecting tool 37 is formed by a rotation center shaft 38 vertically inserted into a hole 11C formed in the upper flange portion 11A of the long side member 11, and a bolt. In order to prevent the rotation center shaft 38 from coming out of the hole 11C, a nut 39 screwed to a male screw portion below the rotation center shaft 38 and a rotation protruding from the upper flange portion 11A of the long side member 11 are provided. An arm member 40 having one end in the length direction joined to the upper part of the dynamic center shaft 38 by welding or the like, and a hole 40A formed in the other end in the length direction of the arm member 40 are formed from above. A bolt 41 inserted and whose head 41A is in contact with the upper surface of the arm member 40, and an E-shaped ring or the like engaged with the bolt 41 in order to prevent the bolt 41 from coming out of the hole 40A. The member 42 It has become a thing that is configured Nde. For this reason, the connecting tool 37 can move in the vertical direction with respect to the upper flange portion 11 </ b> A of the long side member 11 by the distance between the nut 39 and the arm member 40 in the length direction of the rotation center shaft 38. I have.

  As described above, the connector 37 before the two first scaffold panels 1 are arranged adjacent to each other in the left-right direction with no or almost no gap is rotated by the rotation center axis 38. And the bolt 41 is in a rotationally retracted state in which the position of the bolt 41 is away from the first and second connecting members 35 and 36. When the connecting member 37 is in this rotationally retracted state, a hole through which the male screw shaft portion 41B of the bolt 41 can be inserted is provided in the upper flange portion 11A of the long-side member 11, so that the connecting member 37 is moved upward. You may make it possible to be set in the descent state mounted on the flange part 11A.

  As described above, the state in which the protrusion 36A of the second connection member 36 is placed on the groove 35A of the first connection member 35 is maintained, and the tip of the second connection member 36 is After the two first scaffold panels 1 are inserted into the inside of one scaffold panel 1 and are arranged adjacent to each other in the left-right direction with little or no gap, as shown by the two-dot chain line in FIG. Then, the arm member 40 is raised above the long side member 11, and the connection tool 37 is rotated about the rotation center shaft 38. Thereby, after the position of the male screw shaft portion 41B of the bolt 41 is matched with the position of the hole 11D formed in the upper flange portion 11A of the long side member 11, the connecting tool 37 is lowered, thereby the male screw shaft portion 41B. Is inserted into the hole 11D from above, is also inserted from above into the hole 22A formed on the upper surface of the holding member 22, and further reaches the female screw hole 36B formed in the second connection member 36. Thereafter, when the bolt 41 is rotated by a tool or the like engaged with the head 41A, the male screw shaft portion 41B is screwed into the female screw hole 36B.

  As a result, the two scaffolding panels 1 arranged adjacent to each other in the left-right direction with little or no gap are provided with the second connecting member 36 placed on the first connecting member 35 and the second connecting member 36 The connection is established by a connector 37 provided with a bolt 41 having a male screw shaft portion 41B screwed into the 36 female screw hole 36B. Of course, if the bolt 41 is reversely rotated with a tool engaged with the head 41A, the male screw shaft portion 41B can escape from the female screw hole 36B, so that the two scaffold panels 1 can be separated.

  Next, a specific structure of the second scaffold panel 2 will be described with reference to FIG. 5. The second scaffold panel 2 is different from the first scaffold panel 1 shown in FIG. Although provided, the second connection member 36 is not provided, and the connection tool 37 is not provided. In addition, the specific structure of the third scaffold panel 3 will be described with reference to FIG. 6. The third scaffold panel 3 is provided with the second connecting member 36 as compared with the first scaffold panel 1, but the first scaffold panel 3 has the first The connection member 35 is not provided, and the connection tool 37 is not provided. Further, a specific structure of the fourth scaffold panel 4 will be described with reference to FIG. 7. This fourth scaffold panel 4 has both the first connection member 35 and the second connection member 36 as compared with the first scaffold panel 1. It is not provided and the connection tool 37 is not provided. For this reason, the fourth scaffold panel 4 is a scaffold panel without connecting members, and an overall perspective view of such a fourth scaffold panel 4 is shown in FIG.

  As can be understood from the above description, the first to fourth scaffold panels 1 to 4 according to the present embodiment have the same basic structure except for the first and second connection members 35 and 36 and the connection tool 37. . In addition, as described above, these scaffold panels 1 to 4 have a rectangular overall shape in plan view of the panel body excluding the first and second connection members 35 and 36, and have the rectangular shape. The length dimension of the long side is the same for each of the scaffold panels 1 to 4, the length dimension of the short side is also the same for each of the scaffold panels 1 to 4, and the thickness in the vertical direction Since the dimensions of the scaffold panels 1 to 4 are also the same, the first to fourth scaffold panels 1 to 4 share the components such as the long side members 11 and 12 and the horizontal members 13 and 14. And a large number can be manufactured at low cost.

  In FIG. 15, in order to form the temporary suspension scaffold 6 of FIGS. 1 to 3, the two first scaffold panels 1 are moved in the front-rear direction, which is the length direction of the long sides of the first scaffold panels 1. The state when juxtaposed and the first scaffold panels 1 are connected to each other by the first connecting tool 45 is shown. The first connecting member 45 includes a horizontal member 14 provided on the front first scaffold panel 1 and a rear first scaffold panel 1 of the two scaffold panels 1 arranged in the front-rear direction. , And more specifically, the first connecting member 45 includes two clamps for clamping and holding the horizontal members 13 and 14. 46 are connected by a connecting member 47.
