Abstract

PURPOSE:To present the bending method for completing the set process with only one time by arranging all stands of machines for working a reinforcing bar equivalent to the man hour of bending in separating the distance suitable to the working positions. CONSTITUTION:Four stands of the reinforcing bar working machines are arranged at the working positions A1-A4 of the reinforcing bar A, and the reinforcing bar is clamped with the reinforcing bar working machines 1a, 1d of the out end side with hand or automatically except the reinforcing bar working machines 1b, 1c which is to bend at the final. The working machines 1b, 1c are set on the elavating device so that the reinforcing bar clamping part 2 is lowered until the position to be left from the reinforcing bar A. The reinforcing bar is set on the clamping part 2. and worked with the working machine 1a, 1d. Then, after the working machines 1a, 1b are lowered with the elavating device, the bending for A3, A4 parts are worked with the bending machines 1b, 1c. With the method of this invention, the prescribed bending can be executed by only one time of setting, and the efficiency for work is good.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for processing main reinforcing bars of reinforced concrete structures.

(Prior art) Conventionally, this type of main reinforcing bar bending process is a method in which one reinforcing bar processing machine is used to sequentially bend and move the reinforcing bars as many times as the main reinforcing bars are bent. The main reinforcing bars were moved by hand or by a combination of transport machines.

(Problems to be Solved by the Invention) In the conventional method, especially when the reinforcing bar has a large diameter, moving the reinforcing bar by the number of bending processes is not easy because the reinforcing bar is heavy, has poor work efficiency, and is not safe. There were also problems on the surface.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to perform the required bending process by simply setting the reinforcing bar at the reinforcing bar processing position once and without moving it. The purpose of this invention is to provide a reinforcing bar processing method that can be used.

(Means for Solving the Problems) In order to achieve the above object, according to the reinforcing bar processing method according to the present invention, a number of reinforcing bar processing machines equivalent to the number of bending processes for one reinforcing bar are used to bend the same reinforcing bar. After arranging them in series with a distance corresponding to the position, and with the processing level aligned,
The reinforcing bars are set between the respective reinforcing bar processing machines, and then the reinforcing bars are bent by the reinforcing bar processing machines from the outer ends of the reinforcing bars, and when the bending process is completed, the reinforcing bar processing machines are lowered from the processing level and placed in the same position. The reinforcing bars are removed from the processing machine, and the reinforcing bars are bent in the same manner toward the center by the reinforcing bar processing machine.

(Function) According to the present invention, a single reinforcing bar processing machine is installed across the number of reinforcing bar processing machines, which are separated by a distance corresponding to the processing position of the reinforcing bars and is arranged on the same processing level, and which corresponds to the number of bending processes of reinforcing bars. A reinforcing bar is set, and the outer end of the reinforcing bar is bent by a reinforcing machine for both outer ends placed at both outer end processing positions of the reinforcing bar, and when the bending is completed, the reinforcing bar at both outer ends is bent. The processing machine is lowered below the processing level, lowered below the reinforcing bars, and removed from the reinforcing bars.

Next, the reinforcing bar processing machine adjacent to the center side of the front rudder outer end reinforcing bar processing machine bends the processed part adjacent to the outer end processed part of the reinforcing bars, and then the reinforcing bar processing machine is used to bend the reinforcing bars in the same manner as above. By separating the reinforcing bars and repeating the same operation, the reinforcing bars are set between the reinforcing bar processing machines once and the required bending process is performed without moving them.

(Embodiment) The illustrated embodiment in which the present invention is applied to a method for processing a reinforcing bar that is bent symmetrically at two locations, a total of four locations, will be described below.

la, lb, lc, and ld are four reinforcing bar processing machines that correspond to the number of man-hours required for bending one reinforcing bar A, and are placed in series at distances that correspond to the processing positions A+, Az, As, and An of reinforcing bar A. , and a reinforcing bar processing machine 1b that is arranged on a base (not shown) with the same processing level and performs the final bending process.
.

The reinforcing bar processing machines 1a and 1d at the outer ends other than 1c are manually or automatically supported on the base so that they can be raised and lowered.

The lifting device of the reinforcing bar processing machine is attached to the processing machine itself or the base, and the reinforcing bar holding part 2 of the processing machine is attached to the reinforcing bar A.
It is configured to descend to a position where it is detached from.

Then, the reinforcing bar A is processed by each of the reinforcing bar processing machines 1a, lb,
lc.

(See Figure 2) When the bending process is completed, the reinforcing bar processing machines 1a and ld are lowered to the position where the reinforcing bar holding parts 2 of the respective processing machines are separated from the reinforcing bar A, and then the reinforcing bar processing is performed. The reinforcing bar A is processed at the processing position A3. A
4, the reinforcing bar A is bent in step 4 (see Fig. 3), and the required bending process can be performed by simply setting the reinforcing bar A in the reinforcing bar processing machine once and without moving it.

(Effects of the Invention) According to the reinforcing bar processing method according to the present invention, the number of man-hours required for bending the reinforcing bars arranged in series and at the same processing level separated by a distance corresponding to the processing position of one reinforcing bar is reduced. The reinforcing bars are set across the corresponding number of reinforcing bar processing machines, and the reinforcing bars are bent from the outer ends by the reinforcing bar processing machines, and when the processing is completed, the reinforcing bar processing machines are lowered from the processing level and bent from the same reinforcing bar processing machines. The reinforcing bars are separated, and then the reinforcing bars are bent in the same manner as described above using the same processing machine and the reinforcing bar processing machine adjacent to the center side of the reinforcing bars, and the above process is repeated to bend the reinforcing bars once between the reinforcing bar processing machines. The required bending process can be performed simply by setting the machine, and there is no movement during processing, improving work efficiency and safety.
