In recent years, technologies associated with the use of monolithic structures have become increasingly popular in the construction of private and apartment buildings, commercial buildings ...
To give them strength and resistance to loads, a special metal base is formed inside before pouring concrete. Reinforcing bars are tied together with steel knitting wire using a special hook.
Such a tool is sold in any hardware store, or you can make a hook for knitting reinforcement with your own hands.
The use of welding when assembling large-volume frames is not welcomed by specialists in the field of monolithic construction. As a rule, such an effect on the reinforcement rods accelerates the corrosion processes and also degrades the quality of the iron. In addition, welding significantly increases the time and cost of reinforcement.
The tying process involves the use of thin steel wire cut into pieces to securely fix the intersections of the reinforcement bars.
Today manufacturers offer three types of ready-made crochet hooks for making armored belts: manual, screw and mechanical.
The simplest hook consists of a handle , to which is attached a metal rod with a bend at the end. With it, the knitting wire is easily gripped. The bar of the hook is scrolled around its axis, thus creating nodes that hold the reinforcement cage together.
A simple crochet hook suitable for both beginners and experienced builders when working on small sites.
Its advantage is that working with it allows you to quickly understand the binding algorithm and understand the required level of tension in the twists. A video of the process can be viewed on the Internet. Plus, the hand crochet hook is affordable and pretty durable when used correctly.
This tool also consists of a handle and a shaft. Unlike manual, the screw is equipped with a hook in the shape of a drill.
With the forward movements of the handle, it is screwed into it, while simultaneously pulling the wire into the knot. To make a quality twist, the master will need two or three movements. This allows you to perform work on reinforcement with a semi-automatic hook in a shorter time.
Professional builders working on large objects use automatic hooks to tie reinforcement.
They are also called a gun hook.
It is a fully automatic tool. Thanks to the use of such a high-quality tool, the reinforcement is knitted as quickly as possible and allows you to eliminate the large energy consumption of the master.
There is no point in purchasing an automatic hook for home use.It is expensive and designed for large amounts of wire.
Often factory crochet hooks do not fully meet the needs of builders performing reinforcement.
This is due to the fact that their rods may not bend properly.
It happens that the length of the working surface is too short and does not allow making a knot in a hard-to-reach place. In such cases, a homemade crochet hook is twisted.
For the manufacture of hooks, experts use electrodes for welding machines, less often - a piece of steel wire with a thickness of at least 4 mm.
There is no need to create drawings, only the following materials are required:
HELPFUL TIP: If instead of a handle you attach the end of a homemade hook to a screwdriver, then you will get a semi-automatic hook made by your own hands
The process of knitting reinforcement for the device of a foundation, a flight of stairs or a tie, differs only in the type of knitting hook. The knot twisting technology itself does not change. It is usually recommended to immediately cut the steel wire into pieces of 30-40 cm.
Experienced craftsmen first make several test knots in order to visually see how long a piece of wire is required. This minimizes wire consumption.
HELPFUL TIP: If you come across a wire that is heavy to bend, then you can warm it up over a fire for 30 minutes, let it cool down, and then start working.
Stages of reinforcement tying
The whole process is very simple. But before you try, it is better to study the photo of creating reinforcing structures.
