What is the membrane structure? For non-industry people, most of the answers are not known or smattering, the early years ago, the author of the word membrane structure is also very unfamiliar, always feel that with the "structure" of the word is bound to be very abstruse, "membrane", as the name implies, it should be a class of film, but there is no association with construction Engineering. "Membrane structure" is called "tensile membrane Structure", also known as cable membrane structure, tension film or space membrane. It is a structure system with perfect combination of architecture and structure, and it is a stable curved surface with certain stiffness which is formed by the combination of high strength flexible thin film material and supporting system, and can withstand the space structure form of certain external load.
Compared with the traditional architectural model, the membrane structure architecture is a new type of architectural model, and its merits are not to be underestimated. First of all, it has artistry, based on modelling, color science, combined with natural conditions and national customs, can be based on the architect's creative design of the traditional building difficult to achieve the curve and shape, this unique curved surface shape makes it have a strong sense of sculpture. Second, in terms of cost, for large-span space structures, the cost of using a membrane structure is equal to half or less of the traditional building, especially when the long-span building with short construction time is more economical, and the membrane structure can be dismantled and relocated.
At the same time, the membrane structure used by the membrane itself has a good light transmittance, the building space can be naturally diffused during the day, can save a lot of lighting energy. Four, the film surface protective coating (PVDF,PTFE, etc.), with high temperature characteristics, and itself does not stick, falling to the surface of the membrane dust can rely on the natural flushing of rainwater to achieve self-cleaning effect. Five, the membrane structure has a light and stable structure, its weight is one-thirtieth of the traditional building, using this feature can design and organize structural detail components, create a huge non-occluded visual space.
In addition, the membrane structure is a flexible structure, under the action of wind load or snow load will be deformed, membrane structure through deformation to adapt to the external load. Different membrane flexible procedures are also different, some of the membrane material flexibility is very good, not due to folding and brittle crack or breakage, this material is effective to achieve movable, expandable structure of the foundation and premise.
Analogy of the membrane structure to clothing designers design clothes again appropriate however, according to the environment and the application of the different, the architects of the selected "fabric" (membrane material) by size cutting, design a variety of unique architectural styles, and "accessories" (strengthening components, such as steel frame, Steel column or cable) combined with a certain way to produce a certain amount of pre-tensile stress in order to form some kind of space. This structure is widely used, the membrane structure carport, grandstand, toll shed, golf course, channel or entrance, Park landscape sketch, even can be used for sewage pool capping deodorization and biogas tank storage tanks.
Some people say that membrane structure is the darling of the 21st century, indeed, now more and more in the city to see the shape of the membrane structure, it fully exert the structure of a clear art of the United States, and a clever combination of the environment, give a person an elegant romantic feeling, especially at night under the illumination of the formation of a beautiful scenery, Or such as the high wings of Dapeng, or such as graceful dance elves, or such as the cone-pointed cloud dome, in addition to provide practical convenience, but also give people a good visual enjoyment, but also to enhance the city's cultural development level.
