[0024]

The assembled scaffold of the present invention has the following advantages.

(1) Connecting rods are inserted into the vertical pipes on both sides of the H-shaped main body by vertically projecting and connecting the connecting rods. The upper and lower protruding portions of the connecting rods on both sides of the connecting tool are respectively fitted into the connection side ends of the adjacent pipe supports of the upper and lower torii frames adjacent to the left and right sides, and the lower torii frame adjacent to the left and right sequentially, in the middle. A torii-shaped frame and an upper torii-shaped frame are erected, and brace mounting rods of vertical pipes on both sides of a vertically adjacent connecting tool are connected by a brace to form an assembled scaffold. Therefore,

(A) When assembling a scaffold, there is no need for a long pipe for crossing connecting the torii-shaped frames adjacent to each other in the left-right direction as in the related art. The workability is good because the scaffold is assembled.

(B) Since the torii-shaped frames adjacent to each other in the left-right direction are connected by a short H-shaped connecting member, they are lightweight and easy to handle, so that labor can be saved and the work efficiency is improved.

(C) Since the upper and lower protruding portions of the both-side connecting rods of the H-shaped connecting tool are respectively fitted to the adjacent pipe supports of the upper and lower adjacent torii-shaped frames, the upper and lower adjacent torii-shaped frames are adjacent to each other. The connection is surely solid.

(D) Since the brace mounting rods of the vertical pipes on both sides of the vertically adjacent connector are respectively connected by bracing, the upper and lower projecting portions of the both side connecting rods of the above described connector are formed of the upper and lower adjacent torii frame. Together with fitting to the adjacent pipe supports, the torii frames adjacent to the left and right sides are firmly fixed and held, and the scaffold is made robust, which is beneficial for safety.

(2) Since no universal clamp is used, workability is good.

(3) The cloth board is hung on the horizontal rod of the torii-shaped frame and on the H-shaped main body of the connecting tool, and the cloth board can be laid all over the assembled scaffold to form a wide scaffold. And is beneficial for safety.

(4) It is possible to assemble a scaffold of a required size and to construct a scaffold of any size, depending on the number of torii-shaped frames connected, which is practically useful.

(5) Since the number of parts is small, it is convenient for transportation and storage.

(6) It can be easily constructed and easily manufactured at low cost.
