Membrane structure landscape Main materials and properties of

1. Light transmittance:

Translucency is a remarkable feature of membrane structure. Compared with other materials, it has significant advantages in aesthetics and operation; Scatter light, eliminate glare, and diffuse light widely to its internal space; The internal coating of the material has high reflectivity, which can maintain the indoor lighting effect at night; Surface luminescence under nighttime backlighting; Natural lighting, saving energy.

2. Energy savings:

The membrane structure has a beautiful appearance, and at the same time, it creates a natural lighting environment for people. Compared with glass materials, it greatly reduces the heat transfer, and compared with opaque materials, it reduces the indoor lighting power consumption. The impact of using membrane structure on energy problems: in tropical areas, it reduces the power consumption of air-conditioning refrigeration; In cold regions, the power consumption of indoor heating equipment is increased.

3. Acoustic effect:

Architectural acoustics mainly refers to A, the membrane material for eliminating external noise B, and the membrane material for absorbing indoor echo membrane structure, which can allow indoor low frequency noise of 0-60HZ to pass through. For large areas and high special needs, special membrane materials can be used to absorb noise.

4. Fire protection:

The membrane material fully meets the requirements of the fire protection code, so the membrane structure is suitable for any kind of building with the permission of height and clearance. Generally, the automatic fire extinguishing system is suitable for the membrane material, and the fire protection design should be considered as a whole.

5. Durability:

According to the difference of membrane material substrate and surface coating, the service life of membrane material can be divided into five grades: 5 years, 10-15 years and permanent membrane material.

6. Design:

Complete combination of structure and building, form finding to ensure the static balance of the system; Nonlinear stress analysis and large displacement; Reciprocal hyperboloid for form finding of membrane structures; Suitable for wind and snow loads in different regions.
