Temporary outdoor grandstand structure
The structure of outdoor grandstands usually adopts modular design to ensure fast construction, safety, stability and flexible adjustment.
Foundation support system
Base Frame
It is usually made of high-strength steel or aluminum alloy to provide overall stability.
Adjustable foot to adapt to uneven ground (such as grass, sand, hard ground).
Anchor device
Expansion bolts (hard ground) or ground anchors (soft ground) prevent side movement.
Some grandstands are ballasted with counterweight blocks (such as cement blocks) to avoid damaging the ground.
Grandstand frame structure
Main Beams
Longitudinal or transverse bearing beams connect the base to the step structure.
Riser Supports
The stairs that form the auditorium are usually supported by a triangular frame to ensure that the weight of each floor is up to standard (generally ≥500kg/m²).
Guardrails/side reinforcement (Guardrails & Bracing)
Prevents lateral rocking and enhances overall rigidity.
Tread & Decking
Deck Boards
Material: non-slip steel plate, aluminum alloy plate or composite material (such as glass fiber reinforced plastic).
Surface treatment: non-slip lines or coatings to avoid wet and slippery in rainy days.
Seat mounting position
Reserve bolt holes or slots to hold temporary plastic chairs, folding chairs or benches.
Safety protection system
Handrails
The edge of each layer is set, and the height is usually ≥1.1 meters (in accordance with safety standards).
Toe Boards
Vertical baffle (height ≥15cm) at the front of the step to prevent objects or feet from sliding out.
