What is membrane structure

Membrane structure, also known as tensioning membrane structure, is the most representative architectural form in the 21st century. Membrane structure architecture breaks the mode of pure linear architectural style. With its unique modeling characteristics, through the perfect combination of stiffness and softness, force and beauty, it provides architects with greater creative imagination space.

Membrane structure adopts high-strength flexible film material to combine with auxiliary structure in a certain way to generate a certain pretensile stress inside and form a certain spatial shape under the control of stress. As a covering structure or the main body of the building, membrane structure is a type of structure with enough stiffness to resist the external load.

Membrane structure has a strong sense of The Times and representative, is a collection of architecture, structural mechanics, fine chemical industry, material science, computer technology as one of the interdisciplinary application engineering, with high technical content and artistic appeal, its surface can be arbitrarily changed with the architect's design needs. Combined with the overall environment, the construction of a landmark image project, and strong practicability, a wide range of applications. It can not only be applied to large public facilities, such as the roof system of sports venues, airport halls, exhibition centers, shopping centers, parking lots, platform facilities, etc. It can also be used in leisure facilities, industrial facilities, entrance corridors and landmark or landscape architecture, sketch, etc.

1) Large span. Membrane structure light weight, good seismic performance, can not need internal support, overcome the traditional structure in the long span (unsupported) building encountered difficulties, can create a huge no shelter visible space, effectively increase the use of space area.

(2) artistry. Membrane structure breaks through the traditional architectural structure types, relying on modeling and color science, it can combine with natural conditions, give full play to the imagination of architects, and build curves and various shapes that are difficult to realize in traditional architecture according to the creativity, and it is rich in color, full of the flavor of The Times, reflecting the beauty of structural components under stress. With light easy to form a night scene, give a person to enjoy modern beauty.

(3) Economy. Membrane material has a certain transmittance, during the day can reduce lighting intensity and time, save energy; The transmission of colored lights at night can form a gorgeous landscape. Moreover, membrane structure can be disassembled, easy to move, especially in the construction of short-term applications of the long-span building, more economical.

(4) Security. Membrane material has flame retardant and high temperature resistance, can well meet the requirements of fire prevention; Membrane structure is a flexible structure, can withstand great displacement, not easy to collapse. Membrane structure light weight, seismic performance is better.

(5) Self-cleaning. The membrane building adopts the membrane material with protective coating, which does not stick itself. The dust falling on the surface of the membrane material can be washed naturally by the rain and achieve good self-cleaning effect, while ensuring the service life of the building.

(6) Short construction period. Diaphragm cutting, steel cable and steel structure production are completed in the factory, reduce the site construction time, can be carried out at the same time with the lower reinforced concrete structure or components, avoid construction cross, in the construction site is only the steel cable, steel structure and diaphragm connection, installation, positioning and tension process, so the site construction and installation is fast and fast, compared with the traditional construction engineering period is shorter.

(7) Wide application. From the perspective of climatic conditions, membrane structure architecture is applicable to a wide area; In terms of scale, it can be as small as a single tent, garden sketches, and as large as a building covering tens of thousands or hundreds of thousands of square meters. There was even a vision of covering a small town with artificial nature.
