PROBLEM TO BE SOLVED: To dispense with a member and work particularly for blocking up a clearance formed between scaffold boards by narrowing the clearance, when suspending a suspension scaffold by a structure via a suspension chain.SOLUTION: In a scaffold board suspension structure, suspension means 1 for suspending a main steel pipe 22 of the suspension scaffold 16 is composed of an annular body 2 out-fitted to the main steel pipe 22, a suspension rod 3, and a suspension ring 5 connected to the suspension rod 3 via a length adjusting screw mechanism 4 and suspended by a suspension chain 18, and the annular body 2 is composed of a belt-like plate 6 of mutually vertically overlapping both ends by bending in an annular shape, and the lower end of the suspension rod 3 is provided with a screw shaft part 3b penetrating in the vertical direction through a belt-like plate both-end overlapping part 6a of the annular body 2, and the annular body 2 and the suspension rod 3 are screw-fitted to the screw shaft part 3b in a space in the vertical direction between an upper surface of the main steel pipe 22 and an upper surface of a sub- steel pipe 23, and are joined by a pair of nuts 7a and 7b for vertically sandwiching the belt-like plate both-end overlapping part 6a of the annular body 2. |
