STEPLADDER AND STEPLADDER SCAFFOLDING METAL FIXTURE AND STEPLADDER SHELF SCAFFOLDING METHOD

摘要

PROBLEM TO BE SOLVED: To make it possible to adjust the height of an operation floor and to promote operation efficiency in a stepladder shelf scaffolding method using long scaffold boards as joist members by providing contact sections to leg posts upward of tread bars of a stepladder. ;SOLUTION: Contact sections 4 and 4 to leg posts 2 consisting of round steel bars, etc., are provided upward of tread bars 3 and 3 located in requied positions from the inside edges of the leg posts 2 and 2 of a stepladder A. In a stepladder shelf scaffolding method using long scaffold boards 9 as joist members, the outside edge of one side of the long scaffold boards 9 is brought into contact with each of the contact sections 4 to the leg posts 2 and is mounted on each of the tread bars 3, and the outside edge of the other side is hung up on each of the leg posts 2. By the constitution, the long scaffold boards 9 as the joist members are built between tow steplladers A. Therefor, the height of an operation floor can be adjusted by means of the long scaffold boards, and operation efficiency can be promoted even in the ceiling work with less adaptability of an operating posture for the height of the operation floor.;COPYRIGHT: (C)1997,JPO
