Configuration manner null of projection size of jig for fire-resistant canning of steel-frame material and jig itself for fire-resistant canning

摘要

PURPOSE: To obtain a tool for facilitating attaching work and fire-resistant sheathing work to a steel frame material by forming attachment parts at the tip ends of a strip main body comprising an elastic filament body, and setting projection dimensions from a flange of the strip base end to be a predetermined sheathing thickness. CONSTITUTION: At the time of putting fire-resistant sheathing material 9 onto the flange of a steel frame material 7 for sheathing, a strip 20 is adapted to set a thickness to be sheathed in predetermined dimensions. Provided at a strip main body 21 comprising an elastic filament body are attachment parts 24 to be elastically joined to a flange part 8, and a projection length from the flange 8 of the strip main body 21 is set to be a predetermined sheathing thickness. In this manner, attachment can be done readily, and also the sheathing thickness can be set correctly, furthermore, the strip 20 serves as an anchor, resulting in a prevention of the separation of fire-resistant sheathing material 9.
