Abstract

PURPOSE:To easily and quickly connect reinforcing bars as well as strengthen the crossing points of the reinforcing bars by a method in which a semicircular holder and a lever part which connect vertical reinforcement with horizontal reinforcement are formed on an elastic steel wire. CONSTITUTION:The tip of an elastic steel wire of an adequate length is bent into a semicircular form to a holding part A, and the wire is bent at right angle from the part A into a U-shaped form to form a holding part B. A semicircular form similar to the part B is formed in parallel with the part A from an adequate position of the part B and extended to an adequate position to form a holding part C. The end portion of the part C is bent into a U-shaped form to form a holding part D and the wire is bent at right angle from an adequate position of the part D to form a lever part E in parallel with the end line of the parts A and D straightly.

Description

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to firmly, easily, and quickly connect the parts where the reinforcing bars intersect in a criss-cross pattern when assembling the reinforcing bars of reinforced concrete.

To explain the present invention in detail, as shown in each figure, it is composed of holding parts A-B-C-D and lever parts E, and when vertical reinforcement L and horizontal reinforcement 2 are crossed when assembling reinforcing bars, Looking down on the vertical muscle 1, hold the lever part E of the binding metal fitting, put the holding part A under the vertical muscle 1, apply the holding part B to the vertical muscle 1, and put the horizontal muscle 2 under the vertical muscle 1. Place the holding parts A and C over the sides of the horizontal muscle 2, and while pushing down the lever part E towards you, slide under the vertical muscle l, wrap the holding part around the vertical muscle 1, and release your hands. The vertical muscles 1 and the horizontal muscles 2 naturally attack each other, and rotation and displacement can be prevented within the elastic range of the steel wire.

The conventional method is to cut appropriately tempered steel wire (hereinafter referred to as sluggish iron wire or bundling wire) into appropriate dimensions, straighten it, fold it in half, take out the appropriate number of wires, and cut them into vertical and horizontal lines. I achieved my goal by lowering the bottom of the rope, hooking the head of the binding wire with a tool, and screwing it up with the remaining binding wire on hand to tighten it. However, when the vertical reinforcement 1 and the horizontal reinforcement 2 are separated due to irregularities in the work site or bent reinforcing bars, etc., it becomes difficult to carry out the work because you have to hold the binding wire in one hand and the tool in the other. When tying, the tying wire breaks or the head of the tying wire breaks, so it is necessary to increase the length of the tying wire and tie it again.

In the present invention, the strength of the binding metal is adjusted according to the size of the reinforcing bars to be arranged, so it will not break or fall off, and it can be used with one hand, so you can adjust the reinforcing bar arrangement with the other hand. Since it is possible to tie the pieces while straightening them or using tools, the work can be done in a rational and efficient manner.

Claims (1)

[Claims] The tip of an elastic steel wire of an appropriate length is bent into a semicircular shape to form a holding part A, and then bent into a U-shape at a right angle from A to form a holding part B. Similar to A, a semicircle is provided from an appropriate position of B parallel to A, and extended to an appropriate position to form a holding part C. A reinforcing bar binding metal fitting that bends the end of C into a U-shape to form a holding part D, bends it at a right angle from an appropriate position of D, and arranges it linearly on the line of the ends of A and D to form a lever part E.
