  Also in this embodiment, attaching the respective hook members 3 to the main body 2 is achieved by using the side wall portion 25B as the attachment portion and coupling the hook member 3 to the attachment portion by the connector 33 using a bolt and a nut. In the pair of hook members 3A and 3B shown in FIG. 9 and FIG. 10, one hook member 3A corresponds to the widthwise inner side of the main body 2 in one side wall 25B of the two side walls 25B. Attach the other hook member 3B to the inner surface in the width direction of the surface and the outer surface in the width direction via the space member 30, and the main body of the other side wall 25B of the two side walls 25B It is directly attached without the space member 30 in the surface of the width direction inner side among the surface of the width direction inner side of 2, and the surface of the width direction outer side. Further, although not shown in FIG. 9 and FIG. 10, regarding the pair of hook members 3C and 3D, of the two side wall portions 25B, the hook member 3D disposed at a diagonal position to the hook member 3A, Attached to the surface on the width direction inner side of the surface on the width direction inner side and the surface in the width direction outer side of the main body 2 in the other side wall portion 5B via the space member 30 and arranged diagonally to the hook member 3B. The space between the side walls 25B of the two hooks 3C is a space 30 on the inner side in the width direction of the inner side in the width direction of the main body 2 and the outer side in the width direction of the two side walls 25B. Directly attach without intervention. The length dimension of the space member 30 in the longitudinal direction of the main body 2 is smaller than the length dimension of the hook member 3, and the respective space members 30 are housed and arranged inside the main body 2.

  Also in this embodiment, as shown in FIG. 8, two work cloth plates 1 are arranged in series in a connected state, and a pair is arranged at opposing ends of these work cloth plates 1. When the hook members 3A and 3B and the hook members 3C and 3D are locked to the same horizontal bridge 4, the pair of hook members 3A and 3B and the pair of hook members 3C and 3D perform two operations. Because the distance from the widthwise central portion of the main body 2 is different from that of the main body 2 of the cloth plate 1 due to the thickness dimension of the space member 30, the hook member 3A of one work cloth plate 1 and The hook members 3C of the other work cloth plate 1 do not interfere in the width direction of the main body 2, and the hook members 3B of one work cloth plate 1 and the hook members 3D of the other work cloth plate 1 also Does not interfere in the width direction.

  Further, by forming the space member 30 of this embodiment by a thick plate metal material which is the same material as the hook member 3, the hook member 3A of the pair of hook members 3A, 3B is formed of two side wall portions 25B. When attaching the hook member 3A and the space member 30 to the side surface 25B and the upper and lower first and second protrusions when attaching the space member 30 to the surface of the one side wall 25B on the inner side in the width direction of the main body 2 Since positioning can be made in the width direction of the main body 2 by 25E and 25G, positioning portions for positioning the protrusions 25E and 25G in the width direction of the main body 2 with the hook member 3A and the space member 30 By doing this, the work for attaching the hook member 3 and the space member 30 to the side wall 25B by the coupler 33 can be easily performed. The hook member 3D of the pair of hook members 3C and 3D is attached to the inner surface in the width direction of the main body 2 in the other side wall 25B of the two side walls 25B via the space member 30. Therefore, the hook member 3D and the space member 30 are positioned in the width direction of the main body 2 by the side wall portion 5B and the upper and lower first and second protrusions 25E and 25G, and the other side wall portion 25B is formed by the connector 33. Can be attached to

  Further, the first and second protrusions 25E and 25G have the dimension in the vertical direction and the dimension in the longitudinal direction of the main body 2 similarly to the hook member 3, the space member 30, and the side wall 25B. Therefore, the hook members 3A, 3D and the space member 30 can be more reliably positioned in the width direction of the main body 2 together with the side wall portion 25B.

  Furthermore, in this embodiment, the upper and lower dimensions of the space member 30 are the same as the upper and lower dimensions of the base attached to the side wall 25 B of the hook member 3 by the connector 33. Since the vertical dimension is the same as or slightly smaller than the distance between the upper extension 25D and the lower extension 25F provided on the upper and lower sides of the side wall 25B, the base of the hook members 3A, 3D When attaching the hook member 3 and the space member 30 to the upper surface 5E and the lower surface 5G via the space member 30, the hook member 3 and the space member 30 are mounted on the upper surface 5E and the lower surface 5G. It is possible to position the hook member 3 so that the hook member 3 can be more easily attached to the surface of the side wall 5B in the width direction inside of the main body 2 via the space member 30 with the coupler 13.

  Although the thickness dimension of the space member 30 in the embodiment described above is the same as the thickness dimension of the hook member 3, the thickness dimension of the space member 30 is made larger than the thickness dimension of the hook member 3 It is also good.

  The present invention can be used for a worker to get on and perform walking, work and the like on a temporary scaffold constructed at a work site such as architecture and civil engineering.
