The binding of reinforcement is required in order to assemblebox for the future of reinforced concrete construction - the foundation of the house or its entire walls and ceilings. The bars are connected to each other in places where they are crossed by means of a special knitting wire made of metal with a diameter of 0.8-1.2 millimeters, supplied in coils. For this procedure, a hook for binding reinforcement is traditionally used.
Knitting wire is used for joiningcrossed rods. Its ends then need to be twisted by means of pliers, which allows to tighten the connection. Usually for one screed a piece of wire is required, the length of which is approximately 20 centimeters, folded in half. Hook for binding reinforcement greatly simplifies the process. It can be simple or helical. Knitting reinforcement is made by folding the wire in half, then the loop is put on the hook. In this case, the unextended ends wrap around the junction of the rods, after which they are expanded into the device.
A conventional hook for mating reinforcement is rotatedmanually, and the screw-like scrolls itself when it is twisted by the handle, which significantly speeds up the process. Increase even more the speed of work can be through the use of samorezverta. The crochet hook is inserted into it as a tip, with the subsequent scrolling with the help of the specified tool, and not with the hands. Specialized viscers allow to speed up the process, since they are able to connect one node per second. They work from batteries. They can easily load a whole coil of wire.
The simplest hook for binding reinforcement, the pricewhich starts from 500 rubles, is a rod made of metal, at the end curved in the shape of a hook, which provides the convenience of gripping the loop. The rod of elongated shape allows, in combination with the bearing in the handle, to produce the fastest rotation possible, due to this the loop is tightened, fastening the rods.
A screw hook for mating reinforcement hasslightly different design. This is already a mechanized version of the traditional device. It has a similar principle of operation: the tightening of the loop occurs due to the rotation of the tip. However, there is a difference in that the rotation is transmitted to the tip by means of a worm gear during the translational movement of the handle up and down. Mating with this option is much faster, but the cost of this device is higher, so its purchase will be useful only if a significant amount of work.
Sometimes the hook for binding the reinforcement isinefficient solution, for example, when building a large object consisting of monolithic concrete. In this case, the amount of work is very large. For such situations, you can use a special gun for mating, which is coined so as to make one connection per second.
