Scaffolding Steel Pipe Specifications

Scaffolding steel pipe specifications are as follows:

The Q235 ordinary steel pipe specified in national standard GB/T13793 or GB/T3091 shall be used as steel pipe, and the type shall be φ Φ48.3×3.6mm (calculated as φ Φ48×3.0mm in the scheme). The materials shall be supplied with product certificate and accepted before being put into use.
Extended data:

Scaffolds with different purposes shall be selected for different types of engineering construction. Most bridge supports use bowl scaffold, and some also use portal scaffold. The main structure construction landing scaffolding uses fastener scaffolding in the majority, and the longitudinal distance of scaffold stud is generally 1.2~1.8m;; The horizontal distance is generally 0.9~1.5m.

According to the setting of wall bars and load size, the horizontal distance of upright bars of commonly used open double-row scaffolding is generally 1.05~1.55m, the step distance of masonry scaffolding is generally 1.20~1.35m, the scaffold for decoration or masonry and decoration is generally 1.80m, and the vertical distance of upright bars is 1.2~2.0m m.

The allowable erection height is 34~50m. When it is set in a single row, the horizontal distance of upright posts is 1.2~1.4 m, and the longitudinal distance of upright posts is 1.5~2.0m. The allowable erection height is 24m.

The longitudinal horizontal rod should be set inside the vertical rod, and its length should not be less than 3 spans. The longitudinal horizontal rod can use butt fasteners or lap joints. If butt fasteners are used, butt fasteners should be staggered. If lap connection is adopted, the lap length should not be less than 1 m, and three rotating fasteners should be set at equal intervals for fixation.
