PROBLEM TO BE SOLVED: To provide a method of forming a spray frame of a slope face, capable of easy stage setting of reinforcement bars at an accurate position.;SOLUTION: A lath wire net 101 is spread on the slope face, two reinforcement bars 301 of a lower stage are held at a prescribed interval by a pedestal spacer 20 attached to the lath wire net 101, a reinforcement bar 303 of an upper stage is held by an upper spacer 1 locked to the reinforcement bars 301 of the lower stage, and thus the reinforcement bars are set in two stages. A body 2 of the upper spacer 1 is crossed with the lower reinforcement bars 301, lower arm parts 5 integrally disposed at a prescribed interval on a lower surface side of the body 2 are respectively locked to the lower reinforcement bars 301, the reinforcement bar 3 of the upper stage is held by an upper arm part 3 integrally disposed on an upper surface side of the body 2 to be an intermediate position of the lower arm parts 5, mortar or concrete is sprayed along the reinforcement bars, and the spray frame of the slope face is formed.;COPYRIGHT: (C)2013,JPO&INPIT
