Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel reinforcement storage system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar storing system and a reinforcing bar storing method using the same, and more particularly, to a reinforcing bar storing system capable of automatically rusting, drying, bending and storing reinforcing bars.

In general, reinforcing bars are widely used in construction sites. Depending on the characteristics, shape, or application of the material, the reinforcing bars may be used for various types of reinforcing bars such as band bars, main bars, abs, short bars, Bent bars, deformed bars, tensile bars, and high-strength bars.

Since the reinforcing bars are usually manufactured in a line type of m units having a predetermined diameter, the reinforcing bars are stacked and stored in an outer space that is open to the outside rather than the indoor space.

In addition, a pallet made of wood or plastic material is installed on the ground of the outer space where the reinforcing bars are to be loaded, the reinforcing bars being spaced apart from the ground by a distance of at least 20 cm, and a moistureproof cloth is installed on one side of the pallet. The outer surface of the reinforcing bar loaded on the pallet is further provided with a moisture-proof cloth to protect the reinforcing bar from rain, wind and moisture.

However, conventionally, the moisture-proof cloth is easily damaged by external environmental factors or is easily detached from the reinforcing bar, so that the reinforcing bar is disposed in a state of being exposed to the external environment for a long period of time. As a result, the reinforcing bar is corroded by changes in temperature and humidity of the external environment There was a problem.

In order to solve the above-mentioned problems, conventionally, a rust preventive is applied to the reinforcing bar to prevent the corrosion of the reinforcing bar. However, since the rust inhibitor applied to the reinforcing bar over time, There is still a problem that the reinforcing bar can not be safely protected from temperature and humidity changes.

In addition, in the past, a worker has applied an antirust agent directly to a reinforcing bar loaded in an external space using an injector, and then dried the antirust agent by allowing the antirust agent to stand naturally, so that the antirust agent is not evenly applied to the reinforcing bars, There is a problem that not only the workability is lowered due to manual work but also a long working time is required due to the natural drying of the rust inhibitor.

In addition, conventionally, a large number of workforce is required because a plurality of workers carrying a part of the reinforcing bars loaded in the outer space are directly moved to a banding work machine and bent and then moved to another space to be loaded , There is a problem that it is impossible to perform a quick operation.
