PROBLEM TO BE SOLVED: To shorten a time required for construction plate attaching and reduce a cost by providing the female screw of the size fitted to the male screw of a stopping tool provided by partially projecting from construction concrete on the center of a rear face, and using the attaching tool of a construction plate providing a flat part on the surface. SOLUTION: The female screw 2 of the size fitted to the male screw 8' of a stopping tool 8 provided by partially projecting from construction concrete is provided on the center of the rear face of a circular attaching tool 1, a recess 3 is provided except for a circular peripheral edge part and the female screw of the center, and a flat part 4 is formed on the surface to be made the attaching tool 1. An anchor 7 having a female screw 7' is driven in a number of holes 6 opened in the lower face of a concrete ceiling 5 at prescribed intervals, the upper part of the stopping tool 8 having the male screw 8' is screwed on the female screw 7', and the female screw 2 is screwed on the male screw 8' to attach the attaching tool 1. After a plurality of the attaching tools are screw-adjusted to flatly arrange the flat part 4, the construction plate is attached. A time required for construction plate attaching is shortened and cost is reduced by using the attaching tool 1. |
