How does the reinforcement for the foundation of different species bind?

Without the reinforcement, construction of a single foundation is not complete. It does not matter what type it is: tape, columnar or monolithic. And as the materials on the foundation even a simple private house requires a lot (sometimes several hundred meters), then a lot of questions arise. One of them: "How does the reinforcement for the foundation bind?"

It should be noted that this process is rather complicated and requires a lot of time. Knit armature in the shallowly recessed ribbon foundation not everyone will be able to, since in the opening width of 40-50 centimeters the adult man does not fit. For example, on the foundation for a house of small dimensions, 500-600 meters of reinforcement will be required , and this is more than a hundred whips. The fourth part of this quantity will be cut into smaller rods, which will make it possible to create a three-dimensional construction.

Now you can talk about how to knit reinforcement for the foundation. If we talk about the ribbon foundation, then it's done quite simply. Each straight angle between the rods is caught with a wire, and then it is twisted. Where the rods lie at least half a meter, you need to knit in three places - in the center and around the edges. For knitting wire is used, the diameter of which is 1-2 millimeters. It does not take on any carrier functions, just a thicker wire would be difficult to twist. From the reinforcement to the outer part of the structure, it is necessary to observe a distance of 2-3 centimeters. You can buy special fixatives for the armature, then this distance will be observed by itself. Considering how knit reinforcement for a foundation, it is worth noting that experts do not recommend pulling it on the middle line. It will be just a waste of materials and effort.

Knit or cook the armature?

Specialists have long abandoned the welding of reinforcement for various reinforced concrete structures, as its strength is not as high as when knitted by steel wire. For a long time a special machine has been invented, with the help of which it is possible to produce all the necessary manipulations. Such a pistol is quite large, but with its help one knot is fastened in just 2 seconds. The hand with this device will easily reach where it is difficult for a person to squeeze through.

If we talk about how to knit reinforcement for a foundation of a monolithic type, then it is laid horizontally and vertically, tying the intersections with wire, while the ends of the latter are tightened and fastened together. You can use a special hook for this. The wire is folded in half to get a loop, which is put on the hook. The ends of the wire should be wrapped around the joint place of the reinforcement. Then the workpiece is put into the device, and then it is twisted. A simple hook must be rotated by hand, and the screw hooks automatically. It is important to prevent corrosion of the reinforcement, because of which the binding is not possible.

Speaking about how to properly knit the foundation reinforcement, it should be noted that there is another way, which implies the use of a screwdriver. On the place of the tip of the device is inserted a hook that rotates, which allows to speed up the process of binding. You can also use ready-made staples, which do not involve the use of any devices.
