Description

Electric reinforcing bars for civil and industrial use {Electrolytic reinforcing bars for civil and industrial use}

The present invention relates to a reinforcing bar binding machine for construction and civil works used to bind reinforcing bars, timber, pipes, etc. in a construction site. The intersection of deformed rebars is twisted very quickly at a constant number of twists regardless of the skill level of the operator. It relates to an electric reinforcing bar binding machine for construction and civil engineering that can not only be very tightly tied, but also reduce the fatigue of workers.

Wire is often used when installing temporary materials such as a working scaffold in construction or civil engineering, or when reinforcing reinforcement before concrete is placed. Such a wire for binding is called a binding wire, and a rather thick soft iron with a diameter of 3mm or more is called semi-senglish (#10 soft iron). And hand tools to bind them together are called hakama or signal stand.

When striking slabs or reinforcing bars, reinforcing bars are connected when rebars are strung or when the strength of rebars is to be increased. Reinforcing bar binding work requires a lot of time and effort due to the large amount of work strategy. Beginners can't deal well with signal stations, etc., so work is delayed further. And since it is hand-worked, there is a limit to the strength of the bond.

Regarding such problems, the Korean Utility Model Registration Application No. 20-2003-0028220 proposes a rotating tool for reinforcing bars that allows the reinforcing bar to be easily tied and tightened to bind the reinforcing bar and the reinforcing bar at the construction site. . However, this is also a manual operation and has limitations in speed and convenience. And since it is hand-worked, the bond strength may be weak.

Meanwhile, Korean Patent Application No. 10-2008-0052945 proposes a reinforcing bar binding device for easily binding a plurality of reinforcing bars used in construction sites. The reinforcing bar binding device includes: a rebar binding device having a clip member mounted therein, and binding reinforcing bars by the clip member, comprising: a main body having an outlet formed at one end, and detachably mounted therein; A movable member that is slidably mounted on the main body to move the clip member in the direction of the outlet; One end is disposed in the direction of the outlet of the main body and the upper surface is mounted to be spaced apart from the upper surface of the main body, and consists of a guide member guiding the movement path of the clip member, and a first inclined portion inclined downward is formed on the outer circumferential surface of the guide member The clip member is characterized in that the movable member crosses the first inclined portion and is discharged through the outlet.

However, this is also a manual operation and has limitations in speed and convenience. And since it is working with the power of the worker, the strength of the binding may be weak.
