The cable-membrane structure is a stable surface formed by high-strength flexible thin-film material, which is subjected to the tension of other materials, and can withstand a certain space structure form of external load. Because the cable membrane structure itself is light, fast installation, unique shape, energy saving and environmental protection, the use of safety and other advantages, so that it can be widely used. Here we have a look at the cable membrane structure supporting the installation process.

1, the installation of the supporting structure: the steel structure pre-buried → steel structure pre-buried ?ú the production of steel structure → basic pre-buried review → component anticorrosion coating → component fireproof coating → component hoisting.

2, membrane installation: Before the installation of the membrane, the project concerned personnel to carry out a discussion of the program, to determine the detailed installation process and safety of technical measures. Before installation to check whether the appearance of the film is damaged, folds, hot fusion seam whether there is falling off, bolts, aluminum alloy layering, such as whether there is a strain or rust, cable and anchor coating is damaged. We will also be based on the site conditions and construction plans to build the membrane platform, installation of safety nets, large tensile membrane structure, to collect the weather information during installation. During installation, we should pay close attention to the wind direction problem and avoid the vibration of the membrane. In case of strong wind or heavy rain, the construction should be stopped in time and the corresponding safety measures should be taken.

3, the installation of related requirements: Lift beam lifting net cage support should be used in the middle of the ring beam, the net sliding mold cage support should be used on the column top, single-lift grid method, net frame climbing nets can be placed in the middle of the ring beam or column roof, the two ends of the bearing is not linked to the beam, but the single bar fulcrum For this purpose, slide the mounting brackets under the mounting rails. According to the stiffness of the grid frame sub-grid unit in the Assembly bracket, according to the design position assembled, landing assembly Fulcrum, the Assembly bracket to slide forward a sub-section of the grid unit, because the sub-block installation method in small and medium span grid application, can be used as the top of steel pipe, the end of the steel pipe, the height can More convenient. If the height of the grid is heightened when the design takes into account the characteristics of the strip installation, the deflection is not required for the sub-strip installation.

4, installation quality requirements: The surface of the film is not obvious folds, no water, the film surface color uniformity, no obvious pollution of the string color; the link fixed node is firm, the rehearsal is neat, the suture does not fall off, does not have the super tension, the membrane surface does not have the large area nap to injure.
