Disc-type scaffolding construction precautions

Pre-construction:

1. Familiar with the characteristics of the buckle scaffold, including accessories: lock pin, connector, sleeve, disc and other specific methods of use.

2. According to the construction object situation, foundation bearing capacity, and erection height, special construction plans shall be prepared according to the basic requirements of the regulations, and shall be implemented after examination and approval, and the main personnel shall be trained in construction knowledge.

3. The quality of the steel pipe frame and fittings entering the construction site should be re-examined before use.

During construction:

1. The height of the template bracket should not exceed 24m; when it exceeds 24m, it should be specially designed.

2. Adjustable base setting specification: The adjustable base should not exceed 300mm for the exposed screw. The height of the bottom horizontal rod as the bottom of the sweeping rod should not exceed 550mm.

3. Adjustable bracket: The length of the cantilever extending from the top horizontal rod or double channel steel joist is strictly prohibited to exceed 650mm, and the exposed length of the screw rod is strictly prohibited to exceed 400mm. The length of the adjustable bracket inserted into the pole or double channel steel joist should not be less than 150mm.

4. Setting requirements for diagonal rods and scissors supports: When the erection height is not more than 8m, the step size is not more than 1.5m, and the first straddle of each side of the outer frame facing the inner side of the bracket frame body should be provided with a vertical slanting rod, the frame body Vertical slanting rods shall be provided on the whole bottom layer and the top layer, and vertical slanting rods shall be provided in the inner part of the frame body from the bottom to the top and the horizontal direction, or the scissors struts shall be provided with fastener steel pipes. When the erection height is greater than 8 m, the vertical slanting bar shall be full, and the step of the horizontal bar shall not be greater than 1. 5 m. Horizontal slanting bars or fasteners shall be provided for every 4 to 6 standard steps along the height. .

After construction:

Construction workers must wear safety helmets, fasten seat belts, wear non-slip shoes, and safety protection must be improved.

Technicians should regularly check the insertion degree of the scaffolding lock pin to prevent the safety of hidden dangers such as the unstable connection of the accessory and the collapse of the scaffold due to the collapse of the lock pin, the damage of the safety net, and the degree of attachment of the steel springboard.
