15, the frame body build-up or ascension at a time (
Before, all want to conduct a comprehensive inspection, removing the building main body connection influence of ascension with all temporary fixed facilities, confirmed by the inspection acceptance can be stepped to rear can operation condition for homework.
16, the frame body bolts on fittings, lift power equipment, tripping device, for equipment, electronic equipment, maintenance once a month at least.
17, adhesive lifting scaffolding belong to high dangerous operations, during installation, lifting and removal should be designated limits security and supervision and inspection by designated personnel, it is forbidden to throw the material.
18, the frame body used materials and equipment must be strictly checked, serious deformation, corrosion, wear and failure of materials and equipment, is strictly prohibited.
19, in five (
More high winds and heavy rain, snow, fog and other bad weather, the ban on lift and remove operation, and should in advance to frame body reinforcement measures, ban lifting operations at night.
20, the frame body stopped to return to work after a month or more than in six levels of winds, should be a comprehensive inspection on the rack body, to ensure construction safety.
