The movable universal wheel 4 can adjust the position of the operating frame. After the position is determined, extend the legs 5 to fix the operating frame. The operator and equipment enter from between the two first beams 121 of the fixed end 1, and then reach the working platform 3 through the ladder 11. Because all parts of the operating frame are frame structures, it is convenient to extend them from the frame at intervals for operation. When the construction surface is completed, the operator returns to the ground from the ladder 11, then makes the universal wheel 4 contact the ground, moves the operating frame to the next position where construction is required, and repeats the above steps until all inner wall construction is completed.
[0042] The fixed end 1, guardrail 2 and working platform 3 of the operating frame are all detachable structures, which are convenient for transfer, transportation, storage and size adjustment.
