Scaffolding tube specifications:
There are two kinds of steel pipe used to build scaffolding, one diameter 48mm, wall thickness 3.5mm; the other diameter 51mm, wall thickness 3mm; according to its location and role of different, can be divided into pole, Sweeping pole and so on. According to the "construction of fasteners steel scaffold safety technical specifications" JGJ 130-2011 . Scaffolding pipe should be used the current national standard "straight seam welded steel pipe" GB / T13793 or "low pressure fluid delivery welding pipe" GB / T3091 specified in the Q235 ordinary steel pipe; Scaffolding Pipe steel pipe quality should be consistent with the current national standard "carbon structural steel" GB / T700 in the provisions of Q235 grade steel. Scaffolding tube should adopt Φ48.3 × 3.6 steel pipe. The maximum quality of each steel pipe should not be greater than 25.8kg.
Scaffolding tube Introduction:
Scaffolding is our call for the construction of scaffolding materials, because most of the scaffolding are the use of tubular bamboo or steel pipe and other pipe. Phyllostachys pubescens and other bamboo are scaffolding tubes that have been used for a long time, Scaffolding Pipe but because of the lack of safety and durability, it is only used in small buildings such as rural areas and relatively backward urban areas. Modern construction, Scaffolding Pipe the most commonly used scaffolding tube type is steel pipe, because the scaffolding erection to meet the needs of workers operating, but also to meet the scaffolding of the solid and durable features, Scaffolding Pipe so tough hard steel pipe is the best select. The selected steel pipe generally requires smooth surface, no cracks, no bending, not rust, in line with national standards related to materials.
Scaffolding tube for the construction of scaffolding steel pipe generally have two, one diameter 48mm, wall thickness 3.5mm; the other diameter 51mm, wall thickness 3mm; according to its location and role of different, can be divided into pole, horizontal bar , Sweeping pole and so on. ; Steel pipe quality should be consistent with the current national standard "carbon structural steel" GB / T700 Q235 grade steel requirements. Scaffolding tube should adopt Φ48.3 × 3.6 steel pipe. Scaffolding Pipe The maximum quality of each steel pipe should not be greater than 25.8kg.
Scaffolding tube has a variety of specifications, according to the diameter can be divided into: Φ3.0, Φ2.75, Φ3.25, Φ2.5.
Length also has a variety of specifications: 1 to 6 meters and a half meters a specification; can be processed in accordance with customer specifications specifications.
The thickness is generally 2.4--2.7 mm and the diameter is 48 mm.
The surface is generally not handled, Scaffolding Pipe individually coated with anti-rust paint.
Scaffolding tube material: Q195, Q215 or Q235.
Scaffolding tube implementation of the standard: SY / T5768-95 and GB / T3091-2001.
National standard shelf weight of 0.00384 tons per meter, the actual weight of the whole tube: 0.00384X steel pipe length.
The advantages of scaffolding tube are:
1) bearing capacity is large. When the scaffolding geometry and construction in line with the relevant requirements, under normal circumstances, scaffolding single tube column bearing capacity of up to 15kN ~ 35kN (1.5tf ~ 3.5tf, design value).
2) easy assembly and disassembly, erection flexible. Scaffolding Pipe As the length of steel pipe is easy to adjust, fastener connection is simple, which can be adapted to a variety of flat, facade buildings and structures with scaffolding.
3) more economical. Processing is simple, a low investment costs; Scaffolding Pipe if carefully designed scaffold geometry, pay attention to improve the use of steel pipe turnover, the amount of material can also achieve better economic results. Fastener steel pipe frame equivalent to about 15 kg per square meter of building steel.
