Membrane cloth installation is an important task in membrane structure construction. The quality of membrane cloth installation still has a certain impact on membrane structure buildings. So important work can't be ignored. Today I will show a small editor to explain the correct operation guide for membrane cloth installation.
1. Set up a safe and stable aerial work platform in accordance with the construction and installation plan.
2. Hoisting and high-altitude deployment of membrane cloth
PVC membrane cloth, the membrane cloth is folded into a strip from both sides to the middle in an organ style, and the strip membrane cloth is folded into a hoisting piece from one end to the other or from both ends to the middle in an organ style. The width and length of the membrane are according to the hoisting It needs to be determined that after hoisting to the aerial work platform, use hoist and other equipment for traction, first extend the strip to unfold, in order to prevent scratching, multi-lane should be arranged, the strip of membrane cloth should be placed on the aerial platform, and then along the two membranes Tensioners are hung on the cloth boundary, and the spacing is determined by the size of the membrane unit, and the membrane cloth is fully expanded to both sides.
PTFE membrane cloth, unfold the membrane cloth and re-wrap it according to the hoisting requirements, place it on a special hoisting frame, use a crane to hoist the membrane cloth to the aerial work platform on the side of the installation position, and then hang a tensioner along the boundary of the membrane cloth, with the spacing The size of the membrane cloth is determined, the membrane cloth is stretched to the other side to fully unfold, the membrane cloth is wound on the special steel pipe shaft for hoisting, the steel pipe shaft is equipped with a mechanical rotating device, and the membrane cloth is hoisted to the installation position by a crane. Gradually place the membrane cloth in the installation position by swinging the crane and rotating the steel pipe shaft. The high-altitude installation position should be pre-laid with rope net for placing the expanded membrane cloth.
3. Unfold the installation accessories on the ground and then hoist the membrane cloth
Unfold the membrane cloth on the ground and install the accessories, use a small hoist to lift (or lift and transfer) the membrane cloth to just below the installation position, and set hanging points along the periphery of the membrane unit. The spacing depends on the size of the membrane cloth.
Four, matters needing attention
1. When hoisting membrane cloth, several teams must cooperate closely, coordinate work, and conduct unified command. Before hoisting, the exact position of the membrane cloth must be determined to ensure a successful hoisting. High-altitude operators carry their own tools and put them in place, and assist the membrane unit to hoist and unfold in place at any time. After unfolding, the membrane cloth should be temporarily tied, and the fastest Degree to complete the high-altitude connection. When the membrane cloth is installed, the workload of the day must be arranged so that the membrane cloth installed at the end of the day should be connected. If the membrane cloth is large, the connection cannot be completed on the same day, and safe and firm temporary connection measures must be taken before closing.
2. When the membrane cloth is hoisted and unfolded, the wind should not be greater than level 4.
