Abstract: Included is a scaffold body including a plurality of beam members arranged in parallel, a joint connected to end portions of the beam members by a connecting member, and a work floor installed between the beam members, in which the beam member includes a pair of left and right attachment pieces provided at lower ends of the respective end portions of an upper beam material and formed with pin holes, the joint includes a plurality of plates provided in a circumferential direction on an outer periphery of a cylindrical body, the plate includes a recessed portion formed at an upper end; and an insertion hole facing the pin hole in a state of being fitted between the attachment pieces, and the connecting member is a coupling pin inserted into the pin hole and the insertion hole facing each other in a state where the plate is fitted between the attachment pieces.

Abstract: [Problem] An object of the present invention is to provide a scaffold device and a method of assembling the scaffold device, whereby it is possible to reduce the weight of the components that constitute the scaffold device, simplify assembly work, and shorten the time required for assembly.

Abstract: A means for solving the problem is characterized in including: a frame body including a pair of longitudinal beams, a pair of lateral beams, and four coupling members disposed between respective end portions of the longitudinal beams and respective end portions of the lateral beams so as to rotatably connect the longitudinal beams and the lateral beams on the same plane, two or more intermediate beams bridged between the longitudinal beams at a predetermined interval; and scaffolding boards bridged between the longitudinal beams and supported by at least one of the intermediate beams, the number of the scaffolding boards being larger than the installing number of the intermediate beams by one.
