However, the conventional framework scaffold has the following problems, for example.
That is, as illustrated in FIG. 11, the same portal-type building frame 1, the bracing members 2, 2 ′ (2 ′ is slightly shorter than the member 2), the cloth plates 3, 3 ′ (3 ′ is the plate portion 31). To the corner portion BLC of the building BL, and more specifically, to the building corner portion BLC in which two adjacent outer wall surfaces W1 and W2 form a right angle or a substantially right angle. On the other hand, in order to assemble the first frame scaffold A along one outer wall surface W1 and the second frame scaffold B along the other outer wall surface W2, and to make the frame scaffolds A and B continuous, for example, the first frame When the scaffold A protrudes outward from the outer wall surface W1 and the protruding end A ′ faces the second frame scaffold B, a large gap α may be formed between the protruding end A ′ and the scaffold B. ,It is a danger.

When such a state occurs, for example, the free end portion of the cloth plate 3 ″ provided on the horizontal ground 12 of the building frame 1 located at the end of the second frame scaffold B is used as the fabric at the first frame scaffold protruding end portion A ′. Although it is placed on the board 3 ′, a step is generated between the cloth boards 3 ′ and 3 ″, which is also dangerous for the work on the scaffold.
In FIG. 11, ne is an article fall prevention net stretched between the frame scaffolds A and B and the building BL.

  The above is an example of a problem in the conventional framework scaffold, but generally speaking, when two framework scaffolds are installed orthogonally to each other, when it is desired to use both in a continuous manner by filling the gap between the two Similar problems can arise.

  In addition, when two frame scaffolds must be installed in parallel, and when it is desired to bury them between the two, there is no space between them to allow the installation of a third framework scaffold of the same structure as those. Even if such a framework scaffold can be installed, a large gap is created between adjacent framework scaffolds, and it is dangerous, and if a cloth plate is provided between adjacent framework scaffolds to reduce the risk, There is a case where a step is generated between the cloth boards, which may be dangerous.

  Therefore, the present invention makes it possible to easily and easily pass the cloth board between two frame scaffolds installed next to each other in a safe state without a step between the cloth boards or in a safe state with few steps. It is an object of the present invention to provide a cloth board support.

  In addition, the present invention is simple and inexpensive because the cloth plate is provided in a safe state with no step between the cloth plates or in a safe state with few steps between the frame scaffolds installed next to each other.

The third frame scaffold can be easily and easily formed by providing a second fabric board between the cloth plate support member and the lateral ground of the building frame at the end of the other frame scaffold. In addition, at this time, since the cloth board support members constituting the cloth board support body are arranged at the same or substantially the same height as the horizontal ground of the building frame, the second cloth board is installed orthogonally to each other. The two frame scaffolds are arranged at the same height or substantially the same height as the cloth plate, and thus a safe state with no step between the cloth plates or a safe state with few steps can be obtained.

  In addition, for example, when forming a third frame scaffold that connects two frame scaffolds installed in parallel, the cloth plate support is constructed of adjacent building frames at positions corresponding to each other in the two frame scaffolds. What is necessary is just to provide between the ground. That is, the cloth board support member between the building ground connection parts is the same as or substantially the same as the horizontal of the building frame by connecting the building land connection parts at both ends of the cloth board support to the upper end part of the adjacent building frame building land. Can be installed easily and easily at height.

  Then, the third frame scaffold can be easily and easily formed by providing the second cloth plate between the cloth plate supporting members provided between the two frame scaffolds. In addition, at this time, since the cloth board support members constituting the cloth board support body are arranged at the same or substantially the same height as the horizontal ground of the building frame, the second cloth boards are installed in parallel with each other. The two frame scaffolds are arranged at the same height or substantially the same height as the cloth plate, and thus a safe state with no step between the cloth plates or a safe state with few steps can be obtained.
