SOLUTION: A main frame 20 is so constructed that an upper lateral frame 24 is provided on the upper end of a vertical frame 21, a lower lateral frame 22 is provided on the lower end thereof, a hanging frame 25 is provided on the tip of the upper lateral frame 24, a washer 28 with an insert hole for an anchor is provided on the lower end of the hanging frame 25 to point toward the vertical frame 21, a raised frame 23 is provided on the tip of the lower lateral frame 22, and a horizontal wall holding material 26 is fitted to the tip of the raised frame 23. Two or more main frames 20 are arranged side by side at spaces in the same direction, horizontal or oblique bars are fitted between the vertical frames 21 and between hanging frames 25 and connected and fixed, and a scaffold plate 34 is laid on the respective lower lateral frames 24 to constitute the suspended scaffolding 34.
