Description of the Related Art Conventionally, various works have been performed after constructing temporary scaffolds for workers at construction sites of various buildings, civil engineering sites, and the like. When constructing a temporary scaffold, for example, a scaffold component such as a support, a cloth material, a cloth frame, or a preceding handrail brace is used, and the cloth material or the like is connected to the support. As this connection structure, the structure which uses the wedge fixed so that it might protrude below to the edge part of a cloth material, for example, and the pocket fixed to the outer peripheral surface of a support | pillar (for example, patent documents 1-1) is known. 3). The pocket is formed by bending a metal plate and is open upward. A temporary scaffold can be constructed by connecting a plurality of scaffold components by inserting the wedges into the pockets. A temporary scaffold having a connection structure with wedges and pockets is called a wedge-tight scaffold.

  By the way, as described above, a plurality of pockets into which the wedges are inserted are provided on the outer peripheral surface of the support column, but are fixed by welding at predetermined intervals in the vertical direction. It cannot be moved in the circumferential direction. Therefore, for example, when connecting the cloth material to the support column, the cloth material can be connected only at a predetermined height and direction of the pocket, and there is a problem that the degree of freedom of installation of the cloth material is low. For example, even if an attempt is made to install a cloth material between pockets arranged in the vertical direction of the support column, there is no pocket, so that it cannot be installed, and it is extremely difficult to weld the pocket at a desired position on the site.

  The present invention has been made in view of such a point, and an object thereof is to enable a pocket to be easily and surely fixed at an arbitrary position when a wedge-type scaffold is constructed. There is.

In the fixed state, the first clamping member and the second clamping member are fastened to each other so as not to move, so that the relative positions of the first clamping member and the second clamping member do not change. Therefore, the change of the relative position of the clamp provided in the 1st clamping member and the clamp provided in the 2nd clamping member can be suppressed.

  According to a third aspect of the present invention, the width direction center portion of the pocket provided in the first holding member and the width direction center portion of the pocket provided in the second holding member are in the radial direction of the column. It is located on the same straight line extended in this.

According to this structure, the clamp provided in the 1st clamping member and the clamp provided in the 2nd clamping member can be positioned on the same straight line extended in the radial direction of a support | pillar. Thereby, the scaffold component connected to the clamp of the 1st clamping member and the scaffold component connected to the clamp of the 2nd clamping member can be positioned on the same straight line .
