摘要： PURPOSE:To improve the installation precision of a pipe and improve the installation workability by moving, in order, a plurality of pipes over the upper part of a slope along a guide rail installed along the slope by means of a winch installed at the upper part of the slope, and mutually connecting the adjoining pipes. CONSTITUTION:In installation of a plurality of pipes 2 on the slope of a natural ground in a state to mutually connect the pipes, a winch 1 is previously installed to the upper part of the slope and a guide rail 10 is installed on the slope. A truck 20 is first placed on the guide rail 10 and the pipe 2 is placed on the truck 20 in a state that an expansion part 4 is brought into an up state. The truck 20 is then moved to the upper part of the slop along the guide rail 10 with the aid of the winch 1, the expansion part 4 of the pipe 2 is locked to a steel material 5, and a fixing band 6 wound around the periphery of the pipe 2 is fixed to the upper part of the slope. Consecutively, a different pipe 2 placed on the same truck 20 is moved along the guide rail 10 with the aid of the winch 1 and both pipes 2 are mutually connected.

摘要： PURPOSE:To easily assemble a scaffold by foldably installing wheeled leg sections on the stage of the working scaffold, and installing auxiliary wheels for conveyance in the folded state and connecting means between stages. CONSTITUTION:Leg sections 20 with wheels 20b are foldably installed on the back face of the stage section 10 of a working scaffold 1 via brackets 25 and erection holding means 26. Auxiliary wheels 28 for conveyance in the folded state of leg sections 20 are installed outside leg sections 20. Connecting means for connecting multiple working scaffolds 1 are installed at four corners of the stage 10. Auxiliary legs 27 are used for folding and stacking scaffolds 1. Conveyance and assembling can be facilitated.

摘要： PURPOSE:To lift a bridging body under a stable state by pushing up the bridging body by a lifting and lowering means, which is elongated and shrunk repeatedly toward an upper section and elevated, while the bridging body is engaged with a sliding mast having a plurality of gate-bar holes. CONSTITUTION:Sliding masts 5 having a plurality of gate-bar holes 6 in the longitudinal direction are passed and disposed in upright into the holes 4 of a bridging body 3. Lifting and lowering means 8 are installed to the sliding masts 5, and the bridging body 3 is received in the peripheries of column bodies 3a. The lifting and lowering means 8 are elevated along the sliding masts 5 by repeating the engagement and disengagement of lock pins 12 by upper lifting and lowering frames 9, the engagement and disengagement of lock pins 14 by lower lifting and lowering frames 10 and the expansion and contraction of jacks 11, thus lifting the bridging body 3. Column bodies 2 are constructed in spaces in the lower sections of the column-body corresponding sections 3a with the elevation of the bridging body 3, and the column bodies 2 are connected to the column-body corresponding sections 3a and the sliding masts 5 are removed when the column bodies 2 reach specified height.
