Membrane structure landscape The membrane structure has good self-cleaning property: the surface of the membrane materials used for construction has no static electricity, and has no adsorption force to dust, so it is not easy to touch dust. Even if a little dust falls, it is easy to be removed by wind and rain. Therefore, the construction of membrane structures always appears in our vision with a bright and clean appearance. Large span of membrane structure: the membrane structure can be built into a large-span construction without intermediate support columns. In some large public places, stadiums and gymnasiums, it is required to form a large-area open space without columns, which poses a big problem for builders. The problem is greatly simplified by choosing a membrane roof. Because the membrane per unit area is very light, the load bearing of the skeleton is greatly reduced. If necessary, the light roof can be supported by the small pressure difference of air in the room surface.
Good processability of membrane structure: membrane material is a complex spatial surface that is difficult to make with flexible data and rigid data, so it is more convenient to select membrane structure. The membrane material can be supported by the steel skeleton, and can also generate various spatial surfaces by tensioning the rigging. The curved surface generated by the membrane structure is smooth and soft, and can clearly reflect the beauty of the force forming of the membrane. Membrane structure construction is a representative and promising construction method in the 21st century. It breaks the way of pure straight line construction style. With its beautiful curved shape, simple, bright, rigid and soft, strength and beauty, it presents a refreshing feeling, and together provides the construction designer with greater imagination and invention space.
It has outstanding environmental protection, light transmission and self-cleaning properties. PVDF (polyvinylidene fluoride) coating or titanium dioxide coating is selected for the surface of the film material, which has a good heat insulation effect. It can reflect 70% of the solar heat energy. The film material absorbs 17% of its own heat transfer, 13% of its own heat transfer, but its light transmission rate is more than 20. After 10 years of direct sunlight, its brightness can still be kept at 70. The cutting process is only one of the processes in the production process of the product. In this process, it should be strictly planned according to the shape and size required by the user. First, the drawings should be drawn, and then the operation should be carried out by professional technicians. The first is the width of the membrane data: the width of the membrane data should be taken into account when the plane grid is divided during the shape analysis. Try to make the membrane unit contained in a piece of membrane cloth complete, otherwise, determine the position of the gap point of the membrane block through interpolation calculation.
The second is the external curvature: if the curvature of adjacent units differs greatly, it means that the surface is severely distorted in this direction. If the cutting seam is not cut off here and starts again, the gap of the cutting film block will have a large arc here. The general trend of geodesic line can be judged from the change trend of curvature of adjacent units.
