③ semi-closed: block area accounts for 30% to 70% of the scaffolding. ④ partial closure: block area of ??less than 30%. 6. Other ① ladder: Hang dry with a short wooden or steel scaffolding Fuzhou, Fuzhou rope tied to the crossbar scaffolding pipe, when used at the top to make a fixed, large flue catalytic reactor, regenerator, inclined tubes overhaul often used. ② mobile hanging ladder, hanging basket: You can move the fixed ladders or scaffolding basket hanging basket Fuzhou lease, generally located at the top or set the hook slide, hanging on a solid site. 3, scaffolding structures, components exist initial defect, such as the initial bending rods, rust scaffolding rental company in Fuzhou, erection size error, etc. Loaded larger eccentric; 4, and the connection point of the wall, on the scaffold binding variation compared great. Research on the above issues and the lack of systematic accumulation of statistics, probability does not have an independent analysis of the conditions, so the structural resistance multiplied by the adjustment factor is less than 1, its value system and the safety factor of the past by using calibrated OK. Therefore, the design method used in this specification is essentially a semi-probability, semi-empirical. Scaffolding constructed to meet the requirements of this specification is the basic condition for the design calculations.
