Membrane structure application stadiums?

膜结构建筑在体育场馆建设中越来越受欢迎。
膜结构建筑也正成为室外遮阳棚的主流选择。

PVDF、PTFE 和 ETFE 膜结构

膜结构建筑是一种以高强度、柔性膜材为主要结构构件的建筑形式。通过张拉、支撑和节点板连接，可以构建稳定的空间结构。其核心特点是定位轻质、高透光率和外部结构的可塑性。膜结构建筑能够满足大跨度空间的需求，并通过丰富而丰富的创造意的形式设计，现代建筑的美学理念（如大型膜结构体育场、学校看台、网络球场和篮球场；以及室外景观结构体现，如高架步道、公园升降台和酒店顶棚）。在体育场中，膜结构看台凭借其独特的性能和外观，已逐渐成为首选的屋顶材料之一。

I. Technical Principles and Core Components
Membrane structure grandstands mainly consist of three parts: membrane material, supporting structure, and connectors. The membrane material is usually made of polyester fiber or glass fiber base fabric, coated with PVDF or PTFE, which has UV resistance, corrosion resistance, and self-cleaning functions.

The main supporting structure utilizes steel cables or steel frames, employing tensioning technology to create a pre-stressed state within the membrane material, thus ensuring overall stability. Connectors are secured with bolts, guaranteeing both structural strength and ease of future maintenance. The photos clearly show the cable used to fix the structure.

Its design concept leverages the synergistic effects of flexible membrane materials and rigid supports to mitigate wind loads. External forces—such as wind (at speeds of 120 km/h) and snow loads—are distributed across the entire structural system, thereby achieving both lightweight construction and high structural stability.

II. Applicable Scenarios and Functional Advantages: Membrane structures are widely utilized in large-scale venues such as football fields, basketball courts, and gymnasiums, and are particularly well-suited for spaces requiring large spans and column-free interiors. Their advantages are manifested in the following three aspects:
