How many meters is the height of the full-house scaffolding?

Full-house scaffolding height over 50 meters needs expert demonstration.

Dangerous sub-projects exceeding a certain scale must be demonstrated by experts, and construction can only be carried out after the demonstration is passed. For scaffolding engineering, the scope to be proved is:

(1) Erect floor-type steel pipe scaffolding with a height of 50m or above.

(2) Attached lifting scaffold project or attached lifting operation platform project with lifting height 150m or above.

(3) Cantilever scaffold project with a height of 20m or more shall be erected by sectional frame.

Structural Requirements and Technical Measures of Full House Red Scaffolding

When the structure is constructed, the main body adopts full steel pipe scaffolding. Scaffolding can only be used after installation and acceptance by safety inspectors. ?

1, basic requirements:?

Fastener-type steel pipe scaffold is a structure to ensure construction safety. It requires to bear vertical and horizontal forces in the construction process, which directly affects the smooth and safe construction. Therefore, scaffolding must have sufficient bearing capacity, stiffness and stability, and will not collapse, deform, tilt, shake or twist when subjected to various normal loads during construction to ensure safety. ?

2. Load situation:?

Ф 48× 3.5 scaffolding such as steel pipes, fasteners and screws. , vertical and horizontal poles are the main stress components, scissors are the bars to ensure the overall strength and stability of the scaffold, and have the ability to strengthen the scaffold against vertical and horizontal forces, and fasteners are the connectors and force-transmitting components of the scaffold organization as a whole. ?

3. Scaffolding foundation:?

When the scaffold is erected, the scaffold site must be compacted and leveled, and the concrete strength of the foundation structure surface reaches more than 75% of the design requirements. ?

4. Vertical load transfer route:?

Construction load, multi-layer board, square timber, horizontal rod, lead screw, vertical rod, foundation or structural board surface.
