Mating of fittings, ways of mating reinforcement, useful tips

The erection of a foundation of any type can not be carried out without a strong reinforced frame. The binding of reinforcement is not the only manual operation, without which it is impossible to build a foundation. The knitting principle is not new and does not require high qualification. However, a knitter will need some physical effort and skill.

Fittings of all types, connect!

When joining the structural elements of reinforcing cages designed for foundations, the main attention is paid to the binding of the reinforcement. The process of knitting reinforcement is included in the stages of building a foundation when building a private house.

The reinforcement is produced in a certain way according to the reinforcement scheme. Proletarian slogan: "Armature of all types, connect!" Combines the simplicity of the "iron" connection and the properly selected material. Well, here without the advice of professionals simply can not do. And again the Home Master hurries to help.

Methods of reinforcement binding

Theoretically, what could be easier than to connect reinforcing bars. I took a homemade hook in one hand, the wire in the other, and ... However, in practice, the process of joining the reinforcement is determined by the pattern of binding.

The algorithm of binding of reinforcement  for the base is simple and consists of the following manipulations: the wire is folded in half, makes a loop out of it, insert a special hook into the loop and twist the wire. But when twisting any loops of wire there are secrets, similar to the secrets of twisting knots of sailors and fishermen.

"Knit knots" help simple, but such necessary adaptations: mechanical hooks, collets and locks, knitting pistols and flexible wire.

Material for binding reinforcement

Wire for reinforcement is the main material for knitting. Therefore, the quality of the wire will depend on the quality of the junction when fixing the reinforcing bar or frame.

It is preferable to give a low-carbon annealed round wire with a diameter of 1-1.2 mm. Thermally treated wire has better qualities than unfired wire. Wire simply bend, when knitting it does not tear and fits snugly to the reinforcing bar. Wire knitting is supplied in the form of cylindrical linkage, in which there can be up to 1000 pieces of finished lengths from 140 to 180 mm.

Helpful Tips

Manufacturers of reinforcing wire went to meet the wishes of the builders. The wire is already delivered with ready-made rings. Therefore, choosing ties from the wire, take a closer look at the presence of rings at the ends of the wire segments.

What to choose: a cunning hook for mating fittings or a knitting gun

After selecting the connecting element, it is necessary to purchase a knitting device. In the arsenal of devices are popular:

• wire hook

• Pliers

• mechanical hook

• knitting gun.

A primitive device that does not require skills at all is a hook. You can make a hook with your own hands from a simple wire or a large nail. When working with a crochet, the folding of the folded wire is hooked and the wire is twisted.

Pliers are used to create a single connection, so with a vast front of work they will be useless.

The mechanical hook works on the principle of the Archimedes screw, in which, during the twisting of the wire, the end of the hook acquires a rotational motion.

Means of small mechanization is a pistol for mating reinforcement, which is a rechargeable power tool. Having adjusted the basic parameters of "knitting", the armature connection time is shortened to a few seconds.

We will suggest that when knitting the reinforcement by a hook, one unit will require approximately 20 cm of wire. When working with a gun this rate increases to 30 cm.

Helpful Tips

It's time to talk about hooks. In the first place on convenience there is a self-made hook, gracefully curved and with a comfortable handle, polished by time and palms. By the way, in the handle of the homemade hook it is possible to mount a small bearing, which will facilitate the rotation of the wire. The binding of the reinforcement with the help of store hooks leaves scraps of wire. These "tails" have to be removed.

How to make the binding of the armature with your own hand

creation of a trunk frame

You can make the binding of the reinforcement in vertical and horizontal directions. The classic option is horizontal reinforcement, in which the load is evenly distributed on a monolithic foundation.

Initially create a frame around the perimeter of reinforcing bars with a pitch of 25-30 mm. At the same time, the main rods must be laid, which must be located at a single level relative to the basement foundation.

Then, across the main rods are located jumpers, under which are installed longitudinal elements. The longitudinal elements of the carcass trunk are connected with the transverse elements.

The main methods of knitting are: "one overlapping loop" and "two hinges to butt joints".

binding of reinforcement in corners

The complex part of the main frame is the corners. Here the binding of the reinforcement must be made more carefully. Rods in the corners bend and try to overlap the wire filaments in the wall.

An obligatory condition for the angular mating of the reinforcement is the absence of overlapping in a stressed place. The pieces of reinforcement should not be left at a right angle.

Binding of the armature with your own hands with the help of a hook

You can make the binding of the armature yourself with several steps:

• Prepare a piece of wire length of 20-30 cm.

• fold the wire in half with a loop at one end

• We have a loop on the diagonal of the reinforcement cross

• pass the hook into the loop and twist it until the reinforcement is firmly connected.

When the brush rotates with a crochet in hand, the ends of the wire will gently twist. Twisting the wire too tight is not recommended, because the wire can burst. It is enough to create a tight connection.
