Advantages and Disadvantages of Scaffolding Pipe

Several days ago, Prime Steel Pipe shared the brief introduction of scaffolding pipe, I believed that those people who saw that article must have a basic understanding to scaffolding pipe. Today, Prime Steel Pipe will continue to share some information of that, its advantages and disadvantages will be listed below.

Advantages of scaffolding pipe:

1) Bearing capacity is large. When the scaffolding geometry and construction in line with the relevant requirements of the specification, under normal circumstances, the capacity that single tube of scaffolding can bear will reach up to 15kN ~ 35kN (1.5tf ~ 3.5tf, design).
2) Easy assembly and disassembly, erection flexible. As the length of the pipe is easy to adjust, fastener connection is simple, thus it can be adapted to a variety of flat, facade buildings and structures with scaffolding.
3) More economical. Processing is simple, primary investment costs is low; if carefully designing scaffold geometry, paying attention to improve the use of steel pipe turnover, the amount of material can also achieve better economic results. The amount of steel in the building per square meter of fastener steel pipe frame equivalent is about 15 kg.

Disadvantages of scaffolding pipe:

1) Fasteners (especially its screw) are easy to lose;
2) The bar at the node for the eccentric connection, by the anti-slip force transmission load and internal force, thus reducing its carrying capacity;
3) The connection quality of the fastener joint is significantly affected by the quality of the fastener itself and the operation of the worker.

Brief Introduction of Scaffolding Pipe

Scaffolding pipe is usually made up of LSAW steel pipe or ERW steel pipe, its process types include: hot rolled/hot expended, electric resistance/high frequency. It has a variety of specifications, according to the diameter it can be divided into: Φ3.0, Φ2.75, Φ3.25, Φ2.5. Its length also has a variety of specifications: half a meter in a specification from 1 to 6 meters; it can be processed in accordance with customer specifications. The thickness is generally 2.4--2.7 mm and the diameter is 48 mm. The surface is generally not handled, individually coated with anti-rust paint. The material scaffolding pipe is: Q195, Q215 or Q235. The implementation of standard of scaffolding pipe is: SY/T5768-95 and GB/T3091-2001.

Different types of construction use different scaffolding and formwork support. At present, the bridge support frame mostly uses bowl buckle scaffolding, but also uses door scaffolding. The main structure of the construction of scaffolding mostly uses scaffolding scaffolding, scaffolding pole vertical distance is generally 1.2 ~ 1.8m; span is generally 0.9 ~ 1.5m.

Adaptability of scaffolding pipe:

1) to build various forms of scaffolding, templates and other support frame;
2) assembly of bone frame;
3) to set up ramps, sheds, stands and other temporary structures;
4) for other kinds of scaffolding support, strengthen the bar.

The Difference Between Single Row and Integrated Scaffolding

(1) When the building of scaffolding outside the building facade along the line erection height is less than 15m, calculated as a single row of scaffolding; higher than 15m, calculated as a consolidated scaffolding. 

(2) the upper part of the wall outside the building line chooses 1.5m or more, according to the

top of the exterior wall outside the building line or uneven length times the total height of the outer scaffolding erection calculated area; the lower part of the wall in accordance with the vertical part retracts into the envelope projected area calculate according to the appropriate height of a single row of scaffolding itself.     

(3) lighting recessed portion open well: when mouth width (distance between the exterior structure) ≤3.5m, press the recessed portion exterior wall vertical projection area of ​​a single row of scaffolding, light wells mouth with or without connecting beam are calculated together with the external walls of the integrated scaffolding; when mouth width (distance between the exterior structure) 3.5m, press the recessed portion to the inside of the vertical projection area of ​​the external walls of integrated computing m2 scaffolding outside light wells mouth connecting beam, integrated computing and the exterior scaffolding together, without connecting beam does not count scaffolding.     

(4) When the stone masonry regardless of the external walls, height of more than 1.2m, integrated computing side scaffold; when the wall thickness is greater than 40cm, integrated computing side and one side of a single row of scaffolding. 

(5) large equipment base height of more than 2m, its base multiplied by height perimeter shape area (m2) to calculate a single row scaffolding.     

(6) roof daughter wall surface over the roof height 1.2m, according to the inner surface of the vertical projection area to calculate single row of scaffolding. 

Requirements and Measures of Scaffolding Fireproof

Various types of scaffolding fire should work closely with the construction site fire protection and measures should primarily do the following: 

1) scaffolding should be placed near a number of fire extinguishers and fire-fighting equipment, should understand the basic usage and basic knowledge of fire extinguishers. 2) must be cleared up on the scaffolding and Lee carried away construction debris around 3) on the temporary scaffolding or scaffolding near the hot work must be handled in the hot work permit, prior to clean hot work site or non-combustible materials are separated, fire-fighting equipment configuration, and a personal supervision, with the flare types of cooperation, coordination. 4) no smoking on the scaffolding. Strictly prohibited foot rack or store near combustible, flammable and explosive chemical materials and building materials. 5) manage the power supply and electrical equipment, power production must be stopped to prevent short circuits, maintenance or operation of electrical equipment under power to prevent arcing or spark damage scaffolding, or even cause a fire burned down the scaffolding.  

6) use of fire (welding, gas welding, torch, etc.) according to the Fire Services Ordinance and construction unit, construction units apply the provisions of the use of fire and approval procedures, approval and taken certain security measures before being allowed to work.

SHINESTAR attended the Canton Fair in 2016

In April, SHINESTAR has attended the Chinese largest Exhibition, the Canton Fair ( also named The China Impor & Export Fair) in April 2016. In this year, SHINESTAR has present the high quality scaffolding products in front of clients all over the world. As the largest scaffolding pipe manufacturer, we have been the most competitive scaffold pipe exporter in China. Our scaffold pipes are manufactured directly from our invested factories in Tianjin. Meanwhile,we are able to process hot dipped galvanizing, anti-oxidant painting for the scaffolding pipe. The coating process present high anti-corrsion resistance which protects the pipes from water. In general, different application requires different types of construction scaffolding. Currently, scaffold pipe is widely used for structure support. The advantages including large carring capacity, easy assembly and disassembly, flexible erection, and it has lower price. 

The Uses of Scaffolding

Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man made structures. 

Scaffolding belongs to a temporary structure used to support people and material in the construction or repair of buildings and other large structures. The construction and renovation industry.  Painters, window washers, and construction workers who deal with multi-story structures. Scaffolding is most often used for creating a working platform for either building or maintaining structures, but because it is so adaptable, it can be used for a variety of purposes, including: Maintaining the exterior of an existing structure eg. painting. Providing working platforms for workers building a structure. Stair towers for access to other raised platforms such as flat roofs. Suspended platforms, cradles or hanging platforms eg. for bridge maintenance. Platforms on uneven ground for stages or marquees. Stabilising or shoring a structure or tall object to keep it vertical. Temporary roofs. Temporary ring lock scaffolding walkways. Temporary bridges. Temporary buildings eg. storage sheds. River bank or lake-side reinforcement. Ramps. Sign-boards frames and advertising hoardings. Bracing structural props. Racking and storage bays. Hand-rails and edge protection. Masts for aerial. Stage sets for television, film and theatre.
