Why? Landscape of membrane structure The design will be different because the ceiling material used in the membrane structure project is tensile membrane, which is a high-strength flexible material that can be spliced and welded.
The shape of the solid membrane structure can be designed into different shapes according to the needs of the owner.
Determine the plane shape, size, 3D modeling and clearance volume of the building through graphic design, determine the coordinates and structural form of each control point, and select membrane materials and construction plans.
Because the membrane material itself has no compression and bending stiffness, and its shear strength is very poor, it needs to improve its stiffness and stability through the curvature of the membrane surface and the prestress in it. For membrane structures, there is no stress at any time. Therefore, the shape of the bending surface of the membrane must finally meet the mechanical balance under some boundary conditions and some prestress conditions, and load analysis and cutting analysis should be carried out based on this.
The form finding analysis methods of membrane structures mainly include dynamic relaxation method, force density method and finite element method. The loads considered for membrane structures are usually wind and snow. The deformation of membrane material under load is relatively large, and the load distribution will change with the change of shape. Therefore, in order to accurately calculate the deformation and stress of the structure, the geometric nonlinear method is used. Another purpose of the load analysis is to determine the initial preload of the cable and membrane.
Membrane structure features: free building shape, variable support structure and flexible membrane materials make the building shape more diversified, novel and beautiful, and reflect the beauty of the structure. Rich colors can create more free building shapes and More abundant architectural language.
It reflects good economic benefits: the weight of the roof structure of the membrane structure building landscape is only one third of that of the traditional steel structure roof, thus reducing the cost of the wall and foundation. At the same time, new, strange, special shapes and The night view of membrane structure has "building visibility" and commercial effect, and its price benefit ratio is higher.
Short construction period: Membrane structure landscape The processing and production of steel structure parts in the project can be completed in the factory of Lianxin Steel Structure Company according to the design, and only on-site installation work can be carried out. Compared with the construction time of traditional buildings, it is almost twice as fast.
Low energy loss: the film has high reflectivity, low light absorption and low thermal conductivity, which greatly prevents solar energy from entering the room. In addition, the translucency of the film ensures that appropriate natural diffuse light provides sufficient light for the room.
