Membrane structure, also called tensioned membrane structure, It is the most representative and promising architectural form in the 21st century. Breaking the model of pure linear architectural style, with its unique beautiful curved shape, the perfect combination of simplicity, liveliness, rigidity and softness, strength and beauty, presents a refreshing feeling, and at the same time provides architects with greater Imagine and create space.
Have you ever understood the specific advantages of a tensioned membrane structure? Here is SIGMA Group to introduce in detail:
1. The lightness of the structure;
The basic components of a tensile membrane structure system are support columns, tension cables and membrane materials; the steel cables exert tensile stress on the membrane around the membrane to form a hyperbolic parabolic stress state, and the membrane has both structural stress and building roof The dual function of partitioning indoor and outdoor environments; the tensile membrane structure itself is light, only 1/8 of the steel structure, 1/40 of the concrete structure, the membrane structure has a good adaptability to the horizontal seismic force and wind, the structure It has its own mechanism of absorbing seismic force and wind force.
2. The durability of the material;
Membrane material is made of fibers woven into a fabric substrate, and the two sides of the substrate are processed and fixed with resin as the coating material. The central fabric substrate is divided into polyester fiber and glass fiber, and the coating material is used The resins include polyvinyl chloride resin (PVC), poly tetra fluoro ethylene resin (PTFE),difluorinated resin (PVDF), etc.; experiments have confirmed that the thickness of the fabric coating is directly related to the life of the fabric, and after reaching a certain level of coating After the layer thickness, the remaining strength of the fabric has not changed in ten years.
3. Diversity;
As a kind of flexible material, its architectural shape changes in many ways, which is unmatched by other materials. Therefore, it also creates the changeable characteristics of the membrane structure, which fully reflects the shape of the building and the light and elegant dynamic curve appearance. The multi-series colors of the materials further enrich the overall shape of the building. The colors of the materials also have good color fastness and durability, so that the membrane structure building completely gets rid of a monotonous dull repetition, making the building more colorful.
4. Light transmittance and heat radiation resistance;
The translucency of the tensile membrane material and the opaque effect of the concrete or steel roof form a completely different effect. The latter makes the active area dark and produces an uncomfortable contrast between the light and dark areas; the membrane material Its translucency brings great comfort to vision, and its light transmittance ranges from 10% to 21%, thereby increasing free daylight lighting and saving light energy during the day. The light passing through the film is perfectly scattered, reproducing the true color of the space below it; the high reflectivity of the film material (about 75%) avoids a lot of heat radiation and reduces heat transfer, and its shading coefficient is about 0.12.
Tensile membrane structure is a spatial structure system composed of a stable space hyperbolic tension membrane surface, supporting mast system, supporting cables and edge cables. At present, the tensile membrane structure has been widely used in stadiums, commercial facilities, transportation facilities, etc. different area.
