(1) the erection height 50 m or above floor type steel pipe scaffold project;(2) the hoisting height 150 m and above attached type integral lifting engineering scaffolding and divided;(3) the frame body height more than 20 m and cantilever scaffold project.

Scaffolds should check and acceptance in the following stage
(1) the scaffold after the completion of the foundation, before the erection of frame body;
(2) each set-up after 6 ~ 8 m high;

(3) before operation level load;
(4) after reaching design height or in case of level 6 and above wind or heavy rain, after thawed frozen region;
(5) stop using more than one month.

2. The main content of scaffolding regularly check
(1) set of bar connection, even the wall, the structure of the support, the truss was conformed to the requirements;
(2) the ground water, the base is loose, poling is impending, fastener bolt is loose;

(3) more than 24 m high double row, and the scaffold, highly in the more than 20 m and support frame, the settlement of the stud and the verticality deviation
Conformed to the specification requirements;
(4) frame body safety protective measures is in accordance with the requirements;
(5) using overload phenomenon.

Hang scaffolding is acceptable within the basic procedures and requirements include:
(1) in each group to a circle of wall board, hang on the wall inside along the circumference of a circle a circle tripod, laying the plank, on a tripod of annular scaffolding, workers can be set on the springboard for installation on a layer of wall plate;

(2) installed in the spacing layer inside along the circumference of a circle by the regulation at the same level elevation hang a tripod, covered the springboard, the springboard lap bind firmly, installation guardrail;
