The membrane area of QingDao Rio Carnival Walk Street (ETFE) is 5000 square meters, and it only took 50 days to complete the construction. It refers to the main structure of the transparent color single-layer ETFE membrane structure as a steel structure. The ETFE membrane structure is inherently high in appearance and looks transparent and weak, but its physical properties are not inferior to traditional glass roofs. Compared with glass, it has better self-cleaning properties, strong weather resistance, and will not burst and hurt people. What is especially valuable is that as an outdoor roof building, its service life is more than 20 years.

QingDao Rio Carnival Walk Street (ETFE) is a commercial street membrane structure, so it has the characteristics of this commercial street membrane structure. Commercial streets occupy a considerable proportion of the city. The architecture and environment of the commercial street are the windows of urban civilization, representing the level of material civilization and spiritual civilization, and at the same time, they are also an important part of the landscape environment. The membrane structure of commercial street is light and chic with modern style, and it is easy to install and move in various forms. It can be widely used in commercial street design.

So what are the characteristics of commercial street membrane structures?

Light transmittance

The light transmittance of the film structure of the commercial street can provide the required illuminance for the commercial street, which is very important for the energy saving of the commercial street. Through the comprehensive utilization of natural lighting and artificial lighting, the light transmittance of the membrane material can provide a larger space for aesthetic creation in commercial streets. At night, the light transmittance turns the membrane structure into a sculpture of light. Through the appropriate combination of the film material and the light-transmitting heat-insulating material, the multilayer film containing the heat-insulating layer can be made light-transmitting. Even if the spectral transmission is only a few percent, the membrane roof is still bright and transparent to the human eye, and has the look and feel of a light roof.

Flexible

The membrane structure of the commercial street is not rigid and will deform under the action of wind load or snow load. The membrane structure adapts to the external load through deformation. During this process, the radius of curvature of the membrane surface in the direction of the load will decrease until it can resist the load more effectively. The flexibility of the tension structure allows it to produce a large displacement without permanent deformation. The elastic properties and prestress level of the membrane material determine the deformation and response of the membrane structure. The flexibility to adapt to nature can inspire people's architectural design inspiration.

Safety

The lightweight tensile membrane structure designed in accordance with the existing national norms and guidelines has sufficient safety. The light structure can maintain good stability under horizontal loads such as earthquakes. Due to the relatively light weight of the commercial street membrane structure, even if an accidental collapse occurs, its risk is less than that of a traditional building structure. When the membrane structure is torn, if the structural arrangement can ensure that rigid supporting members such as masts and beams do not collapse, the risk will be smaller.

Beautiful

The unique shape of the membrane structure of the commercial street reflects the natural beauty of the building itself. The membrane structure of the commercial street itself and the traditional buildings coordinated with it constitute an interesting landmark building on the ground. The excellent commercial street membrane structure design is an organic fusion of structure and shape, making it stand out, adding vitality to its surrounding space and becoming a supplement and focus of the surrounding environment.

Resist the influence of weather

An important function of the commercial street membrane structure is to resist the influence of various weather changes (such as the sun, rain, wind and snow, etc.) on its internal space, and to maintain the internal comfort of the commercial street. When choosing the form and material of the membrane surface, all possible weather conditions should be considered, and passive methods such as the building itself should be used as much as possible to reduce energy consumption. The porous membrane material can be used as a shielding structure. It can control the transmission and reflection of light, make the commercial street have scattered light, and promote natural ventilation, so that the temperature of the ceiling is the same as the temperature of the surrounding environment, and avoid downward heat radiation. In order to resist wind and snow, the shape of the membrane surface should make drainage smooth and quick, and avoid the formation of water pockets or snow accumulation on it. In the installation and forming stage before prestressing, the tensile membrane structure is very sensitive to these loads. In order to drain the rainwater, the membrane material and joints must be sealed and waterproof, and the edge of the membrane must also be specially designed in detail to prevent rainwater from entering the commercial street.
