PROBLEM TO BE SOLVED: To provide a scaffold which is dissembled into a compact size and facilitates an assemble work, or the like. SOLUTION: A base frame 10 provided in the lowermost part of a scaffold is so assembled that a pair of frames 11 formed by longitudinally erecting a straight projecting part 15 at a prescribed interval are so coupled together in a relative position as to be dissembled by a coupling member 12. Two ladder members 2 are laterally joined with each other by an intervention of a coupling joint member 21 between crosspieces of the uppermost and the lowermost steps. The bottom sides of closed strings 22 of the ladder members 20 are detachably inserted into cylindrical projection parts 15 of the both frames 1 of the base frame 10 into double cylindrical states in their joined states. The closed strings 22 are constituted into the double cylindrical states so as to be adjustable of its height. A scaffold board 60 is laid across the coupled topmost crosspieces 23. When ladder members 20 are added upward, they can be constituted into multistoried ladders. Handrails are appropriately provided on the uppermost step. Baseboards 30 can be so provided horizontally that the cylindrical coupling parts in the both ends are inserted in the upper ends of the closed strings into the double cylindrical states between the top ends of the closed strings 22 positioned in the four corners of the assembled scaffold. Disassembling of the scaffold is executed in the reverse process of the above. |
