Where do you need to knit reinforcement cages: immediately on the wall or first on the ground? Convinced by my experience

Where do you think it is better and more convenient to knit the reinforcement into the armored belt frames: first on the ground and raise them to the walls? Or immediately knit on the wall? Probably, whoever is comfortable. I chose, at first glance, the easiest way for myself, but then I realized my mistake. I had to think and apply ingenuity. But first, the background.

For reinforcement frames and beams of often ribbed floors, I purchased reinforcement. Already at a new price, which has doubled compared to last season.

Length 6 m Among the assortment of diameters, I also purchased smooth reinforcement with a diameter of 6.5 mm for the frames of the armorks. It is almost always rusty. But the 8 mm reinforcement was also brought in, too, which had been in the open air for too long. Apparently not undercarriage, it was in the rain and snow for more than a year.

The delivery was done by the metal warehouse itself (so for 1.5 thous. rub. cheaper). Once again I was convinced that you must always be yourself when loading building materials. The fact is that concrete has poor adhesion to too rusty reinforcement, it works worse. It is forbidden to use it in critical facilities (like floor beams). Do not take her back. I decided to clean it with a grinder with a cord brush.

Yes, for a long time. But the reinforcement for the reinforcement cage of the second floor, which will be combined into a single floor slab without a significant load margin (such a diameter according to the project). Inside the floor, for beams - reinforcement 12 mm. The reinforcement cage of the first floor is used with a diameter of 10 mm.

He cleaned from rust on pallet stands from aerated concrete, twisted together. I also knitted reinforcing frames on them. But to lift the reinforced frame 6 m long on the walls of the first floor and raise it to the second - it turned out that there is a big difference. In addition, the reinforcement cage made of 8 mm reinforcement bends more than that of 10 mm (although the former is much lighter).

Somehow I lifted it to the second floor and threw it on the wall. At the same time, the places of tying with knitting wire weakened and the frame loosened, the fittings slipped from their places and I essentially had to tie up this element of the reinforcement cage (pulling the wire and pulling new).

The second elements of the frame on each wall are two meters long (the outer perimeter of the house is 8.5x9.3 m). Raised them freely without deformation. What to do when there is no helper? I decided to do this:

He brought the reinforcement cage to each wall. I attached a rope to it along the edges and in the center on hooks made of nails. And he clung to the center of the rope with the same hook with another rope. He lifted from above like a crane. So the reinforcing cage was almost not deformed, the places of wire knitting did not weaken.

The most difficult thing was to unfold the reinforcement frame onto the internal load-bearing wall. Shifting it to the partition walls, he moved it to its place.

It was possible to saw the reinforcement cages in half and raise each segment of 3 m.But then they would have to be tied with separate reinforcement rods 1 m long.This is an additional 4 reinforcement rods of 6 m each.

Then I cleaned the fittings for the corners: I sawed 1 m each and bent it in half using a tube and a stop on the container. Tied the corners and the T-shaped connection of the reinforcement cages.

I covered the fittings with polyethylene so that they would not rust after the rain. Because it is still far from pouring concrete.

So what conclusion did I draw for myself? Where is the best place to knit reinforcement cages for an armopoyas? My experience says that if you do it from 6 m long reinforcement and you will lift them yourself, then you need to do this right on the wall. So the binding points will not loosen during lifting and the reinforcement will not slide out of their places. The same should be done if you tie the reinforcement cage straight from one-piece reinforcement 10-12 m long. Or knit the reinforcement cages 3 m each, lift them to the walls and tie them there.

It is more convenient to knit on the ground, but it is really possible to raise the 6 m reinforcing cage only in the way that I showed, or with an assistant. By the way, it is almost impossible to lift a 6 m long reinforcement cage from a 10 mm reinforcement on a rope by hooking it to the center, it is too heavy.
