A simple way to pull together the armopoyas formwork. Without self-tapping screws, bars and pins

Everyone who has poured a strip foundation or an armored belt knows about the methods of tightening the formwork. A difficult and costly method is for studs with tubes that remain in the concrete. Suitable for high foundations. An easy way for armored belts is on bars. It looks like this (before and after pouring concrete):

Bars are attached to the shields and tightening bars are horizontally installed perpendicular to them. If the shields are from the board, then the screeds are screwed directly to them. I used OSB sheets, the formwork in my case is reusable, it will be used in other places.

But after stripping, the following traces remain under the bars:

It is impossible to smooth out the concrete under us with a spatula, and irregularities must be carefully removed with a hammer (until the concrete has gained full strength). You don't have to clean it up, but somewhere there will be blocks laying on a thin layer of glue. Yes, and the floor slabs will be smoother.

It would seem that this method of fastening the formwork is the simplest, but it has this small drawback with traces of the bars. It turned out not. Recently I met this method of fastening (pulling) the formwork, which does not require self-tapping screws and bars:

The armo-belt formwork is pulled together with U-shaped brackets from reinforcement with a diameter of 12 mm. Without any fasteners. Every meter, in literally 10 minutes, brackets are installed. The shields themselves are screwed to the aerated concrete with long self-tapping screws. Below the formwork is not bursting with concrete. Self-tapping screws are needed only so that the shields hold themselves.

Yes, there will be concrete irregularities, but about 1 cm wide (easier to clean). Dismantling is also quick: they tapped from below with a hammer from two edges and pulled out the bracket. A lot of time is saved. But it takes time to make such brackets from rebar scraps. And precision is needed in their manufacture. Although, it will take more time to cut and install the bars. Self-tapping screws and time for their twisting and unscrewing are not needed here.

And if you use this technique for a team of builders, then on subsequent objects there will be a continuous saving in both time and money. If you also have your own formwork made of laminated plywood.

Someone will say that U-blocks are used for an armored belt for a house made of aerated concrete. Factory-made or home-made from sawn blocks (and glued to glue-foam). But they are not suitable for supporting floor slabs. The place for supporting the slab should be completely made of concrete armopoyas. And this requires formwork.
