With the development of society, tourism has become one of the strongest and largest industries in the global economy. The industry position of tourism in urban economic development, and economic role gradually strengthen, drawing of tourism to urban economy, society, employment of driving force, as well as an increasingly important role in promoting the culture and environment. The benefits of the various tourism markets are also different. With the development of tourism, the tourism market is constantly changing and tourists' consumption tendency has changed, and China has gradually shifted from the previous sightseeing tour to the direction of leisure travel quality tourism.

In this environment, good experiences become people's pursuit. The most traditional way of lodging is fast hotels, star hotels and so on. In view of tourism, there are new residential forms such as home stay, hotel, theme hotel and rv camp. These accommodation forms have established regional positioning and population positioning.

 

The structure of membrane structure has the characteristics of diversity and curvature, which is different from other living Spaces. The buildings are not confined to hard shell buildings, but also have soft shell buildings. The membrane structure houses can expand the living space, and the insulation and thermal insulation will be better, which can be integrated with nature.

To create outdoor space, people are outdoors and enjoy nature. Membrane structure houses can experience nature and nature.

The membrane structure house belongs to the temporary building. The structure can be moved without the approval of relevant departments.

 

Membrane architecture is a kind of building system which is the main body of the tensioned membrane. Many are the architects involved in design, starting from the actual use consider relevant elements of architectural design, in order to achieve the architect's construction idea will adopt the new technology and new material, elegant, uniqueness is strong, can fully embody the architect's design characteristics.

Membrane structure is a kind of architectural form which is closely combined with the force structure and the shape design. Simple membrane surface through the light and dark regulation produces extremely attractive space and environmental effect. The design of fine membrane structure can effectively resist the effects of sun, rain, wind and wind. As the main force components of various span structures, it can also choose the transparent and transparent film materials to control the light intensity of entering the interior space, thus satisfying all the design requirements. These features combine to form the tensioned membrane structure unique shape, can say don't have any other structures can be better than light tensioned membrane structure with less material to achieve the function and effect of so many.

Tensioned membrane structure architecture simplicity makes it cannot hide any design flaws, relaxation of tension or discontinuity are fully exposed, and lead to fold and deformation at the membrane surface, reduce the service life of the structure. All the components of the membrane structure are completely visible. It is a kind of unique structure, when the design must weigh carefully, any component design cannot modify, because change any component will affect the geometry of the whole structure and the balance of the peak stress. Therefore, the architect only has a thorough understanding of zhang la membrane structure system to produce excellent works.

The design core of the structure is the boundary condition of the control structure and the geometrical shape of the supporting structure, so as to find the best membrane shape which meets the design requirements. Compared with the traditional architecture design, the design of the tensile film structure is a multi - professional coordination process. In order to achieve the minimalistic design of functional requirements, the architect must work closely with other engineers.

The design of lightweight tensioned membrane structure began with Frei Otto's soap film test in the 1950s. Adaptive search is the basic concept of the new design school he created. His theory of "minimal surface" pioneered the design of modern tensioned membrane. Based on this theory, the minimum surface area of the membrane structure obtained from the specific boundary conditions can be minimized. The main structural feature of this type of tensile film architecture is the uniform distribution of prestress in the whole structure.

The minimal surface within the plane boundary is the plane. However, as long as there is a point on the surface or boundary of the membrane that is not in the plane, each point on the minimal surface of the surface has a double curvature.

Hyperboloids can be positive gaussian curvature (such as inflatable structures), but also negative gaussian curvature (such as prestressed tensile membrane structure). The sum of positive and negative curvature radius of negative gaussian surface is zero.

When the negative gaussian membrane is the reducedplane, the membrane material is the least used. Due to the high efficiency of the structure performance, the membrane structure can be redistributed locally by the large deformation of the membrane surface, without increasing the stress of the membrane surface in the region. These properties make the membrane structure a lightweight structure, that is, it can be both effective and easy to maintain. This is one of the reasons why the structure of the structure is often considered to be powerful.

Tensioned membrane biggest characteristic is to, in the sunlight, the oil film coverage within buildings full of natural diffuse light, without a strong contrast with smooth and shadow, interior space visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the membrane of the roof, and the building's body shape shows a fantastic effect.

The application of ETFE film can replace other products in many ways and show strong advantages and market prospects. This kind of membrane material is extremely good, so-called "soft glass", the quality light, only the same size glass 1%; Good toughness, high tensile strength, easy to tear, ductility is more than 400%; Weather resistance and chemical corrosion resistance is strong, the molten temperature as high as 200 ℃; As an inflatable material, it can control the amount of air recharge, regulate the shading and transmittance, effectively use natural light and save energy. In addition, it provides a good transmittance and also has thermal insulation performance. Quality light, can satisfy the need of ventilation and natural lighting according to need; Not only that, but the membrane also has good acoustical properties, which can effectively eliminate the noise caused by the top of the glass layer. The self-cleaning function makes the surface easy to stain, and the rain washes away a small amount of dirt that is stained.

Membrane structure is the "green building system" of the 21st century. ETFE film is the "green building materials" of the 21st century. With the further development of modern science and technology, mankind faces the mission of protecting the natural environment. Therefore, natural materials and traditional ancient building materials will be light, thin and good performance of high strength lightweight thermal insulation membrane material is replaced, the field on the roof of a building curtain wall and a wider range of application is predictable.

Case effect of ETFE film materials at home and abroad.
