As shown in fig. 1 to 4, the double-deck operation platform can be manufactured and used in the following manner:

step 1, assembling a triangular support: the triangular support is formed by welding a vertical support 4, an inclined support 5, a horizontal support 18 and a horizontal two-row support 6;

step 2, connecting the triangular supports with the wall 7 by using two rows of bolts, and fixing the two rows of triangular supports on the prefabricated wall 7 at certain intervals;

step 3, the tops of the two triangular supports which are placed in parallel are connected with the lower-layer operating platform 3 through bolts, and the outer side end of the operating platform of the horizontal support 18 is welded with a guardrail;

and 4, welding three cross hinge rings 14 on the guardrail at the position 1m away from the operating platform, keeping the hinge holes horizontal, and ensuring that the three hinge holes are on a horizontal straight line. The two rows of operation platforms 2 are connected at one side by a hinge ring 14.

And 5, pre-burying 3 hanging rings 16 on the prefabricated wall 7 at the same horizontal position with the hinged ring 14 of the external hanging rack, so that the other side of the two rows of operating platforms 2 is connected with the prefabricated wall 7.

The double-row operating platform externally-hung frame triangular support is characterized in that a horizontal support 18 and a vertical support 4 are made of 10# channel steel, a horizontal second-row support 6 and an inclined support 5 are made of square tubes with the length of 60mm multiplied by 4mm, the length of the horizontal support 18 is 810mm, and the hole pitch of wall-attached bolt holes of the vertical support 4 is 850 mm; the connection mode is as follows: the horizontal supports 18 are connected with the ends of the vertical supports 4 in a vertical welding mode, the inclined supports 5 are welded at the outer side ends of the horizontal supports 18 and are welded at the 700mm distance from the lower parts of the horizontal supports 18 on the vertical supports 4, and the two rows of horizontal supports 18 parallel to the horizontal supports 18 are welded at the middle points of the inclined supports 5.
