Membrane structure landscape The development and application of this kind of membrane material is relatively mature. This kind of membrane material was developed and applied earlier. It is generally stipulated that the thickness of PVC coating on the intersection of warp and weft lines of glass fiber fabric shall not be less than 0.2mm. Generally, the coating shall not be too thick, and it can meet the use requirements. In order to improve the aging resistance of PVC itself, light and heat stabilizers are often added to the coating. A certain amount of ultraviolet absorbent should be added to light transparent products, and carbon black is often added to dark products as a stabilizer. In addition, there are many methods for the surface treatment of PVC, such as pressing an extremely thin metal film on the upper layer of PVC or spraying aluminum fog, using mica or quartz to prevent the surface from sticking, and the silicone resin has excellent characteristics of high and low temperature resistance, water repellency, oxidation resistance, etc. The film has high tensile strength and elastic modulus, and also has good light transmittance.
The balance of the undulation of the negative Gauss film surface makes the larger structure look like a sculpture free from the shackles of gravity, which makes it exciting to float between heaven and earth. This sculptural texture is exciting both indoors and outdoors. Tensioned membrane structure can enable architects to design a variety of tension self balancing, complex and vivid space forms. With the change of light in a day, the sculptural membrane structure presents different forms through light and shadow. At sunrise and sunset, the light with low incidence angle will highlight the curvature and relief effect of the roof. When the sun is at the apogee, the streamline boundary of the membrane structure will throw curved shadows on the ground. The designed artificial light can also make the membrane structure a sculpture of light by making use of the transparency and reflection of the membrane material.
The structure can be demolished and constructed repeatedly in different places, which is the movability of tensioned membrane structure. It combines nomadic and sedentary architecture. The light and soft characteristics of the membrane material make it easy to transport and quickly build, while it occupies little space when idle. This feature makes the membrane structure very suitable for use as a temporary mobile building, especially when a sudden disaster or an emergency requires shelter for a large number of people in a short time. On the other hand, in addition to its comfort comparable to that of permanent buildings, the movable membrane structure also introduces a new concept in the construction industry, that is, the ownership of houses is separated from that of land. The building is no longer immovable, but movable. This feature of mobility and reusability is of great significance for accelerating the development of modern cities and the transformation of architectural functions in some special areas. Deployability and adaptability: The deployable structure can be regarded as an artificial adaptive system. Like many natural organisms, it can change its own form as needed.
