Scaffold Support Post

The Scaffold Support Post is a vertical load-bearing component in a scaffolding system. It is primarily used to bear the weight of the scaffolding platform, construction loads, and its own weight, while transferring the loads to the ground foundation. As a core component ensuring the overall stability of the scaffolding, its design must balance strength, verticality, and adjustability. It is widely applied in high-altitude operation scenarios such as building construction, decoration, and maintenance.

I. Structure and Core Components

The Scaffold Support Post usually features a modular design, with key components including:

Main Tube: Made of high-strength seamless steel pipes (e.g., Φ48mm, Φ51mm), mostly using Q235 low-carbon steel or Q355 high-strength steel, with a wall thickness of 3-4mm to ensure vertical load-bearing capacity.

Base Plate: A square or circular steel plate (common size: 150×150mm) welded to the bottom of the main tube. It increases the contact area with the ground, distributes loads, and prevents the post from sinking into the foundation.

Adjusting Device:

Base Jack: Installed above the base plate, it adjusts the height through threads (usually with an adjustment range of 0-300mm) to adapt to uneven ground or fine-tune the verticality of the post.

U-Head Jack: Located at the top of the main tube, it is U-shaped and used to support crossbars, scaffolding planks, or formwork. Some can be Fine tune the height (fine-tune the height) via threads to ensure the platform is level.

Connection Nodes: Welded sleeves or pin holes are set at regular intervals (e.g., 500mm) on the main tube, used to connect horizontal components such as crossbars and diagonal braces, forming a stable frame.
