First, why should the fastener-type scaffolds be eliminated? “Non-standard steel pipes” are popular, and the wall thickness of steel pipes generally does not meet the standard. The specification requires the wall thickness of steel pipes to be 3.5±0.5mm. The steel pipes marked as 3mm thick on th

First, the erection of general scaffolding The external wall scaffolding is erected with double rows of Φ48 scaffolding steel pipes and their matching connecting fasteners. Depending on the different parts, it is erected from the ground and the top of the basement. Before erecting from the top o

In construction, scaffolding is one of the indispensable equipment. It can provide workers with a working platform and support structure, making the construction of the project safer and smoother. However, when using scaffolding, it is necessary to choose the right type to ensure construction saf

First, the structural requirements of the scaffolding (1) The height-to-width ratio of the scaffolding should be controlled within 3; when the height-to-width ratio of the scaffolding is greater than 3, anti-overturning measures such as guying or guy ropes should be set. (2) When erecting doubl

1. The scaffolding area is calculated according to its projection area. 2. If the building has high and low spans (layers) and the eaves height is not in the same standard step, the scaffolding area is calculated according to the high and low spans (layers) respectively, and the correspondi

1. What is the function of the scissor brace on the scaffolding? Answer: Prevent the scaffolding from deforming longitudinally and enhance the overall rigidity of the scaffolding. 2. What are the safety regulations when there is an external power line on the outside of the scaffolding? An

1. Scaffolding design should ensure that the frame is a stable structural system and should have sufficient bearing capacity, rigidity, and overall stability. 2. The design and calculation content of the scaffolding should be determined based on factors such as the frame structure, erection

1. Special construction technical plans should be prepared for scaffolding used in multi-story and high-rise buildings; special structural design and calculation (bearing capacity, strength, stability, etc.) should also be carried out for ground-type steel pipe scaffolding, cantilever scaffolding

As a formwork support frame for large-scale construction such as domestic bridges, disc-type scaffolding is now increasingly recognized by large construction companies. Compared with traditional brackets, disc-type scaffolding has the advantages of high erection and dismantling efficiency, safety

1. According to the materials used: steel tube scaffolding, wooden scaffolding, and bamboo scaffolding. Among them, steel tube scaffolding can be divided into disc-type scaffolding (the latest and safest scaffolding at present), steel tube fastener type, bowl-type, door type, etc. 2. According t

The erection height of ground-type scaffolding should not exceed 50m but can exceed 24m. If it exceeds 50m, it needs to be reinforced by unloading, double poles, and other methods. From an economic point of view, when the erection height exceeds 50m, the turnover rate of steel pipes and fasteners

The cup-hook scaffolding consists of steel pipe uprights, crossbars, cup-hook joints, etc. Its basic structure and erection requirements are similar to those of the coupler-type steel pipe scaffolding, and the main difference lies in the cup-hook joint. The cup-hook joint consists of an upper cup
