What should be paid attention to when cutting the membrane structure canopy?

The cutting process is just one of the processes in the production process of the product. In this process, strict planning should be made according to the shape and size required by the user. First, the drawings should be drawn, and then professional technicians should operate.

The first is the width of the membrane material: the width of the membrane material should be taken into account when the plane grid is divided during the shape analysis. Try to make the membrane unit contained in a piece of membrane cloth complete, otherwise, the location of the boundary points of the membrane block shall be determined by interpolation calculation.

The second is the surface curvature: if the curvature of adjacent elements differs greatly, it means that the surface is severely distorted at this position. If the cutting seam does not cut off at this position and starts again, then the boundary of the cutting film block will have a large arc here. The general trend of geodesic line can be judged from the change trend of curvature of adjacent units.

Then is the direction of the boundary: if the boundary is relatively straight, consider using the long side of a membrane block as the boundary. Otherwise, only the short edges of multiple membrane blocks can be spliced to form this boundary.

Aesthetics: because the membrane material is transparent and the weld can be clearly seen in the actual structure, the layout of the cutting seam must be regular and reasonable to form some beautiful patterns to increase the aesthetic feeling of the membrane structure.

If the membrane surface is provided with hold down cable or notochord, the cutting seam shall coincide with the hold down cable or notochord, so that the cable will not disturb the pattern layout of the weld.

Five days before the construction, relevant departments shall be organized to repair various machinery and equipment to be used in the construction, so as to avoid machinery failure during the construction process, which will affect the construction;

According to the requirements of the construction organization design, various materials and tools required for construction, and various lifting ropes used for hoisting, as well as cable wind ropes, etc. shall be equipped;

Welding procedure qualification: butt welding and welding procedure qualification;

Welders and other types of work shall receive pre job training, and work with certificates after passing the examination;

Inspection, maintenance and inspection of all measuring instruments and equipment;

Membrane structure landscape Before the commencement of installation works, organize survey personnel to recheck the vertical and horizontal axis deviation of embedded parts and the elevation of embedded parts, carefully record the recheck data of each line column, and copy the relevant data to the person in charge of the project department, the technical director, and all constructors and construction teams. During construction, each construction team uses this data as the basis for component installation, adjustment and alignment. At the same time, the survey personnel shall be organized to return the docking points of the main arch and the secondary arch to the ground, and the survey marks shall be made on each return point.
