The grid generally refers to the steel structure grid, which is generally used as the roof structure of the large-span building structure. Nowadays, people generally refer to the grid structure as the grid structure building.

The cable-membrane structure can be used as an independent structure for roofing or architectural sketches. Generally used in garages, landscape sheds, wind and rain playground sheds, etc.


Construction technology of grid and cable membrane structure


1. Installation of supporting structure
The supporting structure installation process is: steel structure embedding → steel structure embedding → steel structure production → foundation embedding review → component anticorrosive coating → component fireproof coating → component hoisting.


2. Membrane installation
Before the membrane body enters the site for installation, relevant personnel of the project should be organized to review the construction plan and determine the detailed installation operations and safety technical measures. First review the dimensions of the support structure, so that the installation error of each control point is within the allowable range of the design and specifications; check and accept the factory certificate, product quality guarantee, test report and variety, specification and quantity of the membrane body and accessories; Check the appearance of the membrane body for damage and wrinkles; whether the heat fusion seam has fallen off; whether the bolts, aluminum alloy bead, and stainless steel bead are strained or corroded; whether the cable and anchor coatings are damaged. While organizing the acceptance of components, a membrane deployment platform should be set up and safety nets should be installed according to site conditions and construction plans. For large-scale tensile membrane structures, weather information during installation should be collected. Pay close attention to the wind direction and speed during installation to avoid vibration of the membrane. In strong wind or heavy rain, the construction shall be stopped in time and corresponding safety protection measures shall be taken.


3. Installation quality requirements
The membrane surface has no leakage, no obvious wrinkles, and no stagnant water; the membrane surface has uniform color and no obvious pollution and cross-color; the fixed nodes are firmly connected and arranged neatly; the sutures are not falling off; there is no over-tension; Scratch.
