During construction, safety accidents often occur due to quality issues with scaffolding, resulting in significant casualties and significant property damage. Therefore, construction companies must adhere to the correct concept of “people-oriented and safety first” during the construction process, strictly control the quality of scaffolding installation, and ensure safe construction. Below is an example to demonstrate the scaffolding installation method at a safe construction site for your reference..
The tightening torque of bolts should be controlled between 40N · m and 65N · m; The inspection and acceptance of bolt tightening torque must be carried out using a torque wrench. When the quantity of tightening torque that does not meet the standard reaches a certain value, all bolts should be re tightened:.
Scissor braces are continuously set, spanning 4-6 upright poles at an angle of 45 to 60 degrees. The overlapping length of the scissor brace is greater than or equal to 1m. Use no less than 3 rotating fasteners for fastening:.
Scissor braces should be set continuously, spanning 4-6 upright poles at an angle of 45 to 60 degrees, with a lap length of 1m or more:.
Separate horizontal bars and safety nets should be installed at the unloading platform and construction elevator for easy removal:.
The main construction should prioritize protection, and the outer frame should be raised more than 1.5 meters above the working floor:.
After the layout of the channel steel is completed, check and correct the overhang length by pulling through the line to ensure aesthetics:.
When the channel steel passes through the shear wall, it should be protected by wrapping it with polystyrene board at the opening of the wall to facilitate future removal. At the same time, reinforced steel bars should be set according to the design requirements:.
The horizontal rod should be locked onto the positioning pile welded at the top of the channel steel to ensure the overall stability of the frame:.
Install longitudinal and transverse horizontal bars. The height of the one-step scaffolding should be controlled according to the height of 4-6 floors, and should not be too high. Firstly, the scaffolding height is too high, which poses relatively high safety hazards. Secondly, when the main structure of high-rise buildings is capped, the two-step scaffolding above can generally be gradually flipped down after completing the exterior wall decoration, which will accumulate a large amount of turnover materials and increase construction costs.
