1. Steel pipe fastener scaffolding
Referring to Industry Standard 130-2011, the Ministry of Housing and Urban-Rural Development issued a document stipulating that steel pipe fastener supports shall not be used as cantilever scaffolding. However, some areas have issued a comprehensive phase-out.
Advantages: simple structure, high bearing capacity, and flexible erection.
Disadvantages: Fasteners are easily damaged and lost, and their safety is low.
Technical points: Steel pipe fasteners should be of high quality and safety should be paid attention to when erecting them.
2. Bowl-buckle bracket
Refer to industry standard 166-2016. The Ministry of Housing and Urban-Rural Development has not stipulated it, but some areas have issued documents to eliminate it.
Advantages: high bearing capacity and good stability.
Disadvantages: Complex installation and inconvenient movement.
Technical points: The bowl buckle joint should be strong and reliable, and safety should be paid attention to when erecting it.
3. Socket type disc buckle bracket
Refer to the industry standard 231-2010, which is fully recognized and has stable performance.
Advantages: high bearing capacity, good stability, flexible erection.
Disadvantages: higher cost.
Technical points: Socket-type disc buckle nodes should be strong and reliable, and safety should be paid attention to when erecting them.
4. Wheel buckle bracket (inline disc buckle type)
Association Standard 3-2019, performance has been reduced. There is no industry logo, only the association logo 3-2019, which is prohibited in some areas.
Advantages: Flexible installation and low cost.
Disadvantages: low bearing capacity and poor stability.
Technical points: The wheel buckle nodes should be strong and reliable, and safety should be paid attention to when erecting.
5. Portal scaffolding
Referring to industry standard 128-2010, the Ministry of Housing and Urban-Rural Development issued a document stating that it cannot be used for load-bearing support. Be cautious when investing!
Advantages: simple structure and easy installation.
Disadvantages: low bearing capacity and poor stability.
Technical points: The door frame nodes should be strong and reliable, and safety should be paid attention to when erecting.
In addition to the above five common scaffolds, the following types of scaffolds are also commonly used:
6. Cantilevered scaffolding
Referring to industry standard 130-2011, cantilevered scaffolding is widely used in various construction projects.
Advantages: high bearing capacity, good stability, flexible erection.
Disadvantages: Requires special support structure, higher cost.
Technical points: Cantilever nodes should be strong and reliable, and safety should be paid attention to when erecting them.
7. Mobile scaffolding
Referring to industry standard 166-2016, mobile scaffolding is suitable for various construction projects.
Advantages: Flexible installation and easy movement.
Disadvantages: low bearing capacity and poor stability.
Technical points: Mobile scaffolding should have reliable moving mechanisms and support structures, and safety should be paid attention to when erecting.
8. Aluminum alloy scaffolding
Aluminum alloy scaffolding has the advantages of being lightweight, beautiful, and corrosion-resistant, and is suitable for various construction projects.
Advantages: light, beautiful, corrosion-resistant.
Disadvantages: lower bearing capacity and higher cost.
Technical points: Aluminum alloy scaffolding should have a reliable support structure and moving mechanism, and safety should be paid attention to when erecting it.
The above is an introduction to several common construction site scaffolds. Each scaffold has its own advantages, disadvantages, and scope of application. The selection and use need to be evaluated and selected according to the specific situation. At the same time, no matter what kind of scaffolding is used, it is necessary to strictly comply with relevant safety regulations and technical requirements to ensure construction safety.
