Column welding

Column welding

When you are a new site engineer at a construction site. Then you have to be a little careful to prevent wastage. Suppose a total of 15 columns are welded to your site today, the size of 20 "x25" and height 8'-3 ". If the height is more than 5'-0", you should cast two lifts.
The description of the rod is given in the drawing. The ratio will be (1: 1.5: 3) stone casting, with 100% Sylhet sand.
1. The column kicker comes first in the case of columns. Adjust the column placement with the gridline yarn and insert the kicker. The kicker's mold must be flawless and tight. If possible, insert a ring on the column inside the kicker section. The size of the kicker will be less than 6mm on either side than the original column size.
2. The next day, you can untie the kicker. But don't miss the curating.
3. Call the rod maestro this time and instruct the main rods and rings of the columns to be restrained. Help him tie the rod while drawing.
4. Before setting the sitter, wrap the foam around the outside of the kicker molding with duck gum.
5. Before setting the sitter, you should check the column rods, rings, lapping, etc.
6. Masters will call you after setting the sitter to check the column verticality. You will check the vertical by hanging the brick or brick or block. You can get a maximum discount of up to two mm.
7. Then make sure that the columns are drawn and pushed. Check whether the column saturation is free of leakage. Make sure the column is covered.
8. Prepare for welding. In advance, calculate how much welding will be required.
= 15x1'-8 "x2'-1" x8'-3 "= 429.44 Cft Total.
Now you see (1: 1.5: 3) that if you make a load of spices it will be 4.583 Cft.
Then you need load = 429.44 / 4.583
= 93.70 = 94 loads.
In this case, you should tell your account to the mixer machine operators. He will continuously make 85 loads of spices. You will calculate the rest later.
I said less because the rod is inside the column, so the welding volume will be reduced.
9. Welding tanner should be made in relation to the speed of the laborer. Water should be sprayed inside the column before casting. And after a while, the cement grouting needs to be poured.
10. Welding will continue to pour and vibrate periodically. But it should only vibrate until the weld is equal and the air bubbles come out. If you hold on for a long time, the crust will go down and the sand, cement will come up.
11. Mold all the columns in the same way. Immediately after casting, you can see if the column is upright and look with your eyes. After casting you will see the coverings again.
12. After making 85 loads, measure the residual column, and repeat how many loads of spices you need. Then you will see no waste.
13. Don't open the sitter the next day. 1 day to be tough during the day. However, in the morning, you will water it with a water pipe on the head of the column.
14. After the opening of the third day, if you see that the cleaning has become a surface. Then you will feel good about yourself. I like that too.
15. Then do the curling on the column and do the curing.
# Caution
1. Do not move until the welding is finished. Then the laborers can trap you and give you soil inside the column.
2. Of the columns
