linen jewelry pouches wholesale Below is a very detailed construction engineering steel bars tied to hidden acceptance content, which has a very strong guiding effect on actual work:
1 Dark column content:
1.1 The cement slurry on the roots of the pillar root has been cleaned.

1.2 In order to ensure the accurate position of the main bolt of the dark column, the fixed -frame control 1.3 column reinforced bars are tied:
1.3.1 The number of column stirrup determines according to the requirements of the drawing. 50mm from both ends start setting. The demand is required to be adjusted by 1: 6. The wall ribs are staggered by 50%, and the staggered distance is not less than the 1.3 times overlap length of the adjacent connector. The top mold is brushed the rust -proof paint. The above items must not be tied up. The joints must be tightened, so that the two reinforced heads should be tightened or locked at the center of the sleeve. The sequence of the tie is the first step and then the platform.

17
The signal worker when the steel bars are lifted should be directed when there is no person in the pile.

19 The excess of the leftovers of the installation class must be returned to the production class and fulfill the signature procedures.
