Different types of engineering construction choose different uses of scaffolding and formwork support. Most bridge support frames use bowl buckle scaffolding, but also the use of portal scaffolding. The main structure construction floor scaffolding use fastener scaffolding in the majority, scaffolding pole longitudinal distance is generally 1.2~1.8m; The transverse distance is generally 0.9~1.5m.


Specifically introduce the structure of insulation scaffolding

Insulating scaffold compared with the general structure, its working conditions have the following characteristics: the load variability is larger; The joint of the coupler is semi-rigid, and the size of the rigid node is related to the quality of the coupler and the installation quality, and the performance of the node has great variation.

There are initial defects in the structure and components of the insulating scaffold, such as the initial twists and turns of the rods, corrosion, scale error and load bias, etc. The connection point with the wall has a great variation in the constraint of the scaffold. The research on the above problems lacks systematic accumulation and statistical data, and does not have the conditions for independent probability analysis.

Therefore, the adjustment coefficient of the structural resistance multiplied by less than 1 is determined by the calibration with the previously selected safety factor. Therefore, the planning method selected in this standard is classified as semi-probabilistic and semi-experiential in nature. Scaffolding meets the basic conditions for structure planning and calculation specified in this standard.
