2022 China New Design Spatial Truss - Large span steel PVDF membrane structure for stadium bleach in Nicaragua – HJZC

Detail Specifications

Membrane material classification Class

Class A is best, which is made of glass fiber fabric coated with PTFE (permanent film material);

Class B is second, which is made of glass fiber fabric coated with PVC;

Class C is the second of the three categories, which is made of polyester (polyester) fabric coated with PVC. According to the coating materials, there are polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), polyvinyl chloride (PVC), polyurethane (PU), rubber, etc. Its service life varies with different surface coatings, generally up to 12-50 years.

Advantage

1.Beautiful architectural style
Membrane structure architecture is the most representative and promising architectural form in the 21st century. It breaks the pattern of pure straight-line architectural style, with its unique beautiful curved surface shape, the perfect combination of simplicity, brightness, rigidity and softness, strength and beauty, giving people a refreshing feeling, and at the same time providing architects with more imagination and creative space.

2.Good environmental protection, light transmission and self-cleaning PVDF (polyvinylidene fluoride) coating or titanium dioxide coating is used on the surface of the film, which has a good heat insulation effect. It can reflect 70% of solar heat, absorb 17% of the heat and transfer 13% of the heat. However, the light transmittance is above 20%. After 10 years of direct sunlight irradiation, its brightness can still keep 70%.

3.Covering large-span space
The membrane material used in the membrane structure is about one kilogram per square meter. Because of its light weight and the adoption of high-strength materials of steel cables and steel structures, it is simple and reasonable with the stress system-most of the force is transmitted by axial force, which makes the membrane structure suitable for spanning large space and forming an open long-span structure system without columns.

4.Fire resistance and earthquake resistance
The membrane materials used in membrane structures have excellent flame retardancy and high temperature resistance, so they can meet the fire protection requirements. Because of its light weight, flexible structure and large deformation capacity, the structure has good seismic performance. Short duration:

5.Film cutting.
The steel structures and steel cables for assembling and framing are all manufactured in the factory, and the construction is simple and convenient, so the construction period is shorter than that of traditional buildings.
