Landscape membrane structure Do you know the key points of material selection? The development of membrane structure and membrane structure curtain wall depends on the technological revolution and development of membrane village. Historically, the revolution of material technology has brought more and more ideas to architecture, and also brought endless high requirements.
From the perspective of architectural color science, we can see the color of the interior through the color or nature of the building facade. From light to dark or from dark to light, the Shanghai membrane structure scene shed. Architects can achieve their desired architectural optical color function according to the depth of the layout, the arrangement of color cooling and heating, and the similarities and differences in the direction of light sources day and night.
Because membrane structure works are mostly used in some large buildings such as stadiums, when membrane structures are selected to make closed buildings, the single-layer membrane materials used have the same thermal insulation as brick walls, and are better than glass. The interior of the same building can also adopt various methods to improve the internal temperature like other buildings. For example, add a thermal insulation layer. After all, the lining material has the characteristics of heat preservation, non condensation, light transmittance, etc.
Why can different shapes be planned for the membrane structure scene? 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 fixed membrane structure can be planned into different structural styles according to the needs of the owner.
Confirm the plane shape scale, 3D modeling, clearance volume of the building through figure planning, confirm the coordinates and structural forms of each control point, and select membrane materials and construction plans.
Since the membrane material itself has no compression and bending stiffness, and its shear strength is poor, its stiffness and stability need to be improved by the curvature change of the membrane surface and the prestress in it. As for the membrane structure, there is no stress free state at any time, so the shape of the membrane surface must be satisfied with the mechanical balance under certain boundary conditions and prestress conditions, Based on this, load analysis and clipping analysis are carried out.
The tensile film material also has very good flame retardancy and high and low temperature resistance, and can withstand temperature changes between - 73 ℃ and 232 ℃. The optical refractive index of the surface of the tensile film material can reach more than 70, and the transmittance is 25. Therefore, membrane structure buildings do not need artificial lighting to maintain in the daytime. Moreover, the sunlight directly from the roof provides living conditions for plants and creates an ecological environment for the interior.
