The invention discloses a scaffold convenient to disassemble. The scaffold comprises two brackets and a connecting chain; each bracket comprises two vertical rods and transverse rods connected to the tops of the vertical rods; spiral fixed pieces are arranged on the transverse rods and the vertical rods at fixed intervals; fixed rods are arranged between the two brackets; and the two ends of the fixed rod are fixed at the endpoints of the transverse rods correspondingly. The connecting chain comprises two or more connecting rods; round rings are fixed at the two ends of the connecting rods; the adjacent connecting rods are connected through the round rings; and the rings at the two ends of the same connecting rod are also connected to the two brackets through the fixed pieces correspondingly. Using of the connecting chain and the fixed pieces is more convenient and faster compared with mounting and disassembly of a traditional scaffold, and the construction efficiency is improved to a certain extent; and the connecting chain and the transverse rods or the vertical rods form a plurality of triangles, so that the stability of the scaffold is greatly improved.
