Scaffold tube is easy to dismantle, set up flexible, can adapt to the change of flat façade of the building, high strength, can set up a large height, sturdiness and durability.
Scaffold pipe refers to the construction site for workers to operate and solve vertical and horizontal transport and set up a variety of stents. The general term of the building industry, which refers to the construction site with external walls, Scaffolding Pipe interior decoration or higher floors can not be directly constructed. Mainly for the construction staff to work up and down the perimeter safety net maintenance and High-altitude installation components, and so on, plainly is Shing, scaffold pipe production materials are usually: bamboo, wood, steel pipe or synthetic materials. Some projects also use scaffold tubes as templates, in addition to advertising, municipal, road and bridge, Scaffolding Pipe mining and other departments are widely used.
China in the early 1949 years ago and the 50 's, the construction of scaffold tubes are used bamboo or wood erection methods. 60 the promotion of fastener-type steel pipe scaffold pipe.
Since the 80 's, China in the development of advanced, multi-functional scaffold tube series of achievements, such as the door-type Scaffold pipe series, bowl buckle-type steel pipe Scaffold pipe series, Scaffolding Pipe annual output has reached tens of thousands of tons of scale, and has a certain number of exports.
In fact, the scaffold tube search has many kinds of specifications, according to the diameter can be divided into: φ 3.0, φ 2.75, φ 3.25, φ 2.5.
Length also has a variety of specifications: 1 to 6 meters a half meters a specification, can be in accordance with customer requirements specifications processing.
The thickness is generally 2.4--2.7 mm, and the diameter is 48 mm.
The surface is generally not treated, individually painted antirust paint.
The Scaffold tube material is: Q195, Q215 or Q235.
Scaffold Pipe implementation standards are: Sy/t5768-95 and gb/t3091-2001.
National standard shelf tube weight of 0.00384 tons per meter, the actual weight of the whole tube: 0.00384X steel pipe length.
Different types of engineering construction use scaffolding and formwork support for different purposes. At present, the bridge support frame using the majority of the bowl buckle scaffolding, but also the use of door scaffolding. The main structure of the construction of the scaffold using the fastener scaffolding, Scaffolding Pipe the scaffolding vertical bar is generally 1.2~1.8m; the transverse distance is generally 0 aged. 5m.
Its advantages are:
1) The bearing capacity is larger. When the geometrical dimension and the construction of the scaffold conform to the relevant requirements of the specification, the bearing capacity of the single pipe column of the scaffold can reach 15kn~35kn (1) in general. 5tf~3. 5TF, design value).
2) easy to install and dismantle, flexible erection. Because the length of the steel tube is easy to adjust and the fastener is easy to connect, it can be adapted to various planes, facades of buildings and structures with scaffolding.
3) More economical. Processing is simple, the cost of one investment is lower; if the scaffold geometry is carefully designed and the working rate of the steel pipe is improved, Scaffolding Pipe the material dosage can also achieve better economic effect. The steel pipe frame of fastener is equivalent to 15 kg per square metre.
