Membrane structure landscape The design mainly includes body shape design, initial balance shape analysis, load analysis, cutting analysis and other four major issues. Determine the plane shape, size, 3D shape and clearance volume of the building through figure design, determine the coordinates and structural form of each control point, and select membrane materials and construction scheme. Initial equilibrium shape analysis is called form finding analysis.
Since the membrane material itself has no compression and bending stiffness, and the main shear strength is very poor, its stiffness and stability need to be improved by the curvature change of the membrane surface and the prestress in it. For the membrane structure, there is no stress free state at any time, so the shape of the membrane surface must finally meet the mechanical balance under certain boundary conditions and certain prestress conditions, Based on this, load analysis and clipping analysis are carried out.
At present, the main form finding methods of membrane structures are dynamic relaxation method, force density method and finite element method. The loads considered for membrane structures are generally wind load and snow load. The deformation of membrane material under load is large, and the load distribution is changing with the change of shape, so the deformation and stress of the structure should be accurately calculated by geometric nonlinear method.
The membrane structure shed is a kind of building used as a barrier to protect vehicles from damage. It is mainly used to prevent wind and rain. Common materials include color steel plate, sunlight plate, endurance plate, clean plate, sandwich plate, membrane structure, etc. The membrane structure shed is suitable for schools, businesses, stadiums, factories, government agencies, etc. The installation equipment used for the construction of the membrane structure shed must be strictly inspected before use.
Carry out insulation voltage test before using hand-held automatic tools; The hand-held glass sucker and the glass sucker construction machine must be subject to the adsorption component and adsorption duration experiments. The installation personnel shall be equipped with redundant rest and protective equipment to prevent personnel and objects from falling. Prevent solvent acid poisoning of sealing materials in engineering application, and control the solvent to prevent fire. When riveting on site, the crossfire bucket shall be added below the weldment. Full time underwriters shall be assigned for operation monitoring and patrol inspection.
