Design principles and precautions for membrane structure grandstand ceilings

The membrane structure sports stand ceiling is a new type of building structure. Its design enables it to store and utilize heat in the venue while providing sight blocking. At the same time, this kind of building structure also has the advantages of earthquake resistance, weather resistance and easy maintenance. This article will delve into the design principles, structural composition and construction precautions of membrane structure sports bleacher ceilings.

1. Design principles

Lightweight: The membrane structure sports grandstand ceiling has high span and stiffness, and is extremely light in weight, so that it will not cause excessive pressure on the grandstand during operation.

High strength: High-strength steel cables are used as support rods to ensure that the membrane structure sports stand ceiling has sufficient load-bearing capacity.

Easy to maintain: The membrane structure sports stand ceiling adopts modern processing technology and maintenance methods to ensure that it is always in good condition during daily use.

All-weather adaptability: The membrane structure sports stand roof can adapt to different climate conditions, including extreme weather such as high temperature, low temperature, rain and snow, ensuring the smooth progress of the event.

Game viewing experience: The roof of the membrane structure sports stand is made of light-transmitting materials to ensure that the audience can enjoy an even and shadow-free line of sight at any angle. In addition, considering the need for post-game maintenance, the membrane structure roof adopts a movable Steel structure that is easy to disassemble and assemble. 

2. Structural composition

Ceiling frame: Hot-dip galvanized high-strength steel cables and supporting steelspace  frames are used to ensure the overall rigidity and stability of the ceiling.

Support rods: High-strength steel is used as the main material to form a membrane frame support system to provide a stable platform for spectators to watch the game.

Sealing material: High-performance fluorocarbon coating material is used to effectively prevent water vapor from condensing and improve the comfort of the internal environment of the stands.

Sunshade facilities: Adjustable sunshade facilities can automatically adjust the angle and intensity of the sunshade cloth according to climate conditions, creating a pleasant viewing environment for the audience. 

3. Construction precautions

Build scaffolding: Strong scaffolding must be built before construction to ensure construction safety.

Stand foundation construction: Before installing the membrane structure sports stand ceiling, the stand foundation construction needs to be carried out first to ensure that the foundation quality meets the standard.

Fire prevention measures: During the installation of membrane structure sports stand ceilings, relevant fire regulations should be followed to ensure fire safety on the construction site.
