Just after Christmas, although it is not our Chinese holiday, everyone is still immersed in a happy atmosphere. She showed me a lot of gifts yesterday. My heart is so beautiful! I have said that Xiaobian has been working for a few years at Shiyi Membrane Structure Company. In retrospect, when I first came to work at Membrane Structure Company, I was a person who did not understand what membrane structure was, and had not even heard of membrane structure. people. After years of study and contact, Xiaobian has also been included in the membrane structure industry. Today, I will review the definition and classification of membrane structure with Xiaobian.
Membrane structure is one of the first new building structure methods, and its origin can hardly be estimated. Prototypes of restored membrane structures based on local archeological discoveries date back to more ancient times. The membrane structure is composed of a variety of high-strength thin-film materials and reinforcing members (steel frames, steel columns, or cables) through a certain method to cause a certain pretension in the interior to form a certain spatial shape, and can accept a certain external load. A spatial structure method.
Classification of membrane structure: According to different structural methods, membrane structure can be divided into three categories: skeletal membrane structure, inflatable membrane structure and tensile membrane structure.
1. Skeleton membrane structure: It is a structural method of laying a membrane on the frame of a steel frame or other materials to form a roof or an external wall. The shapes include flat shapes, single curved shapes, and hyperbolic shapes represented by saddle shapes.
2. Inflatable membrane structure: It is a structural method of filling air into the interior of the membrane structure, and insisting that the pressure of the indoor air is always greater than the pressure of the outdoor air, thereby putting the membrane in tension to resist loads and external forces. There are two methods of single-layer structure and double-layer structure.
3. Tensile membrane structure: It is a structural method composed of stretching the membrane material on the structure through a cable, and the membrane's appearance changes to its internal and external force balance through its own curvature change.
