Main materials and properties of architectural membrane structures

1. Transparency:

Translucency is a remarkable feature of the film structure. Compared with other materials, it has significant advantages in both aesthetics and operation; it scatters light, eliminates glare, and can diffuse light widely into its interior space. ; The inner coating of the material has a high reflectivity, which can maintain the indoor lighting effect at night; the surface glows under the backlight at night; natural lighting saves energy.

2. Energy saving:

The membrane structure is beautiful in appearance, and at the same time creates a natural lighting environment for people. Compared with glass materials, it greatly reduces the heat transfer. Compared with opaque materials, it reduces the electricity consumption for indoor lighting. Impact of energy problems: In tropical regions, electricity consumption for air conditioning and cooling is reduced; in cold regions, electricity consumption for indoor heating equipment is increased.

3. Acoustic effect:

Architectural acoustics are mainly A. Eliminate external noise B. Absorb indoor echoes

The membrane material of the membrane structure can allow the indoor low-frequency noise of 0-60HZ to pass through. For larger areas and higher special needs, special inner membrane materials can be used to absorb noise; of course, the membrane material can reduce the blocking ability of external noise. is limited, so when the external noise isolation requirements are high, the membrane material may not be suitable.

4. Fireproof:

The membrane material fully meets the requirements of the fire protection specification, so the membrane structure is suitable for any kind of building under the allowable height and clearance. Usually, 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 the membrane material base material and surface coating, the membrane material life is divided into several 5 grades: 5 years, 10-15 years and persistent membrane materials.

6. Design:

Complete combination of structure and building, form-finding to ensure the static balance of the system; non-linear stress analysis and large displacement; reciprocal hyperboloids of membrane structure form-finding; suitable for wind and snow loads in different regions.
