When designing the membrane structure, the designer should ensure that the membrane surface has sufficient stiffness after tensioning; The possibility of secondary tensioning shall be considered in detail structure design; The secondary tensioning shall be stopped in time for the loose film surface. The node design shall ensure the degree of freedom of rolling to comply with the tear or deformation of the membrane surface under the action of wind.
The membrane surface of membrane structure shall minimize the proximity of combustible objects. Corresponding fire-fighting equipment shall be set strictly according to the requirements of building design fire prevention standards.
The methods of form finding and analysis of membrane structures mainly include 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 also changing with the change of shape. Therefore, several nonlinear methods should be used to accurately calculate the deformation and stress of the structure.
The sunshade has full external shading function, which can block the ultraviolet radiation, reduce the indoor temperature, and reduce the air conditioning load; The awning has the function of energy saving, which is very significant from the perspective of energy saving and environmental protection; The sunshade cloth of the awning has a special anti ultraviolet function. The awning has a variety of patterns and colors of sunshade cloth, which users can choose according to their needs. Membrane structure sunshade
It has outstanding environmental protection, light transmission and self-cleaning properties. The surface of the membrane material is coated with PVDF (polyvinylidene fluoride) or titanium dioxide, which has a good heat insulation effect. It can reflect 70% of the solar heat energy. The membrane material itself absorbs 17% and conducts 13% of the heat, while the light transmission rate is more than 20. Through 10 years of direct sunlight, its brightness can still be kept at 70.
