Telescopic welded bellows, steel bellows will be damaged because of those reasons.
1. The bellows that are transported to the site must be stacked neatly and should not be stepped on.
2. The steel bellows should be covered and protected to prevent premature aging due to wind and rain.
3. The cut steel bellows should be straight and not beveled.
4. Corrugated pipe joint method: The bellows joint should be covered with a large corrugated pipe of 0 to 3 meters long, and the two ends should be tightened in half, and no gaps should be left in the middle. In order to ensure that there is no gap in the middle, a mark should be made at the ends of the two joints. After finishing, wrap it tightly with tape to prevent slurry leakage.
5. The location of the steel bellows should be accurate, especially near the joints. The spacing of the corrugated pipe positioning steel bars is 0.5 meters, which is indispensable.
6. When the welded steel bar is close to the corrugated pipe, measures should be taken to protect the steel corrugated pipe from being burned. If it is accidentally burned, the burned area should be tightly wrapped with tape.
7. Considering that the number of corrugated pipes on the roof is gradually decreasing, all components that conflict with the corrugated pipe should avoid the corrugated pipe.
8. When pouring concrete, do not discharge the material against the corrugated pipe. The vibrator cannot collide with the bellows, and it is strictly forbidden for two vibrators to clamp a bellows to vibrate. Especially when the web is vibrated, it is strictly forbidden to vibrate the vibrating rod in the same position for a long time, and the vibrating time shall not exceed 20 seconds.
9. When disassembling the mold, pay attention to protect the corrugated pipe leaking at the end.
