DEFORMABLE TRUSS FRAMING OF SUSPENDED SCAFFOLD

Japanese Patent JP3489447

B2

PROBLEM TO BE SOLVED: To provide a deformable truss framing for a suspended scaffold excellent in work efficiency capable of being transferred with the transfer of a wall surface of a structure in a suspended state while keeping the suspended scaffold moved up and down.
SOLUTION: Diagonal members 5 having variable lengths are provided along diagonals of quadrilaterial links 4 connecting two pairs of chord members 1a in all directions in a rotatable manner to form plate frames 12, the plate frames are arranged up and down at a specific height of interval to constitute basic space trusses 14 of the minimum constitutive unit vertically connecting four corners with struts 13, and a large number of basic space trusses 14 are connectively provided along an exterior wall surface 15a of a building 15 in the horizontal direction while sharing the struts 13 and chord members 1a to form a truss framing 10 of a working suspended scaffold. While keeping the lengths of both upper and lower diagonal members 5 in the same size in each basic space truss 14, a form of the truss framing 10 can be optionally deformed only by changing the lengths of the diagonal members 5 in between the basic space trusses 14.
