Title:
SCAFFOLD BOARD
Document Type and Number:
Japanese Patent JP3867235
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To use scaffolding boards even for circular scaffolds having different diameters by providing a transfer means that one of the inside claw and the outside claw moves to a relatively longitudinal direction against the other, between one of the inside claw and the outside claw for engagement and the scaffold board body.
SOLUTION: The scaffold board 1 is provided with a scaffold board body 2, an inside claw 3a, an outside claw 3b, and a transfer means 4A. An auxiliary board 40 is rotatably pivoted to a pin 41 whose axial center crosses the scaffold plane at right angles, at the longitudinal end of the scaffold board body 2. The inside claw 3a and the outside claw 3b are arranged in the auxiliary board 40. And hence, an angle at which a straight line connecting respective engaging centers of the inside claw 3a and the outside claw 3b and that of the other end cross mutually can be arbitrarily set. Therefore, if respective dimensions of the scaffold board 1 are predetermined, the set angle of the auxiliary board 40 and the arranged angle of a lateral frame member 6 can be easily calculated as a function of the radius of a circular instrument, and the angle can be used for a bent scaffold formed by prefabrication of scaffold frames 5 and a polygonal scaffold in common. Accordingly, it can be used for a polygonal scaffold having different disposed angle or a straight long scaffold as well.
