How to ensure the stability of steel support?

How to ensure the stability of steel support?
The appearance of the steel support components entering the site must be inspected, and the use of steel with rust, bending, cracks, and weld defects is strictly prohibited; Accessories such as flexible connectors, flanges, bolts, etc. must match the specifications and be free from deformation and damage to avoid connection failure due to material defects.

Core application scenarios of steel support

Core application scenarios of steel support
Excavation support: This is the main purpose of steel support. When excavating deep foundation pits, it is used to cooperate with underground continuous walls, piles and other enclosure structures to withstand the horizontal pressure of the soil and avoid overturning or deformation of the enclosure structure. It is commonly used in subway stations, high-rise building basements, municipal tunnels and other projects.

Precautions for installation and use of scaffolding

Precautions for installation and use of scaffolding
Before installation: A special installation plan should be developed based on the project situation, approved by the technical leader, and the material quality should be checked, the site should be leveled, and drainage measures should be taken.

How to choose the appropriate type of scaffolding?

Low rise/multi story buildings (≤ 10 floors): Priority should be given to floor type fasteners/bowl type steel pipe scaffolding, which has low cost and stability to meet requirements; If it is for indoor decoration or small-scale masonry operations, portal scaffolding or inner scaffolding can be used for easy installation and dismantling.

What are the common types of scaffolding?

Floor standing scaffolding: directly erected from the ground (or floor slab), with a base plate and base set at the bottom, vertical uprights and horizontal crossbars forming a whole frame, and diagonal braces on the outside to enhance stability. It is suitable for exterior wall construction of low rise and multi story buildings.

The core advantages of scaffolding

When the geometric dimensions and construction comply with the specifications, the bearing capacity of a single tube column can reach 15-35 kilonewtons (design value), which is suitable for heavy-duty scenarios such as concrete pouring.

Key points of steel support construction

Strictly adhere to the principle of "layered excavation, support before excavation", and closely coordinate the installation of supports with earthwork excavation.

Application scenarios of steel support

Deep foundation pit support: Steel supports (such as φ 609 or φ 800 steel pipes) are used to control the deformation of the foundation pit through prestressing technology and resist lateral soil pressure.

The core advantage of steel support

Steel supports can be prefabricated and quickly installed on site, achieving a cycle of "installation today, excavation tomorrow" and significantly shortening the construction period.
