Abstract

PURPOSE:To improve workability by suspending previously-assembled wall- reinforcements, after joint reinforcements are inserted into spaces placed between hoop reinforcements, and the main reinforcements of previously assembled column- reinforcements are vertically arranged, and by moving said wall-reinforcements to the sides of the joint reinforcements in the horizontal direction, to be bound with the joint reinforcements. CONSTITUTION:Into spaces placed between the main reinforcements 1 and hoop reinforcements 2 of previously assembled column-reinforcements A placed horizontally on a trestle, joint reinforcements 3 are inserted to be erected at the same pitches as those of previously assembled wall-reinforcements B so that the tips of the reinforcements 3 may be projected from the reinforcements A. After that, the reinforcements A are erected at specified positions and after that, the reinforcements B are suspended to positions confronted with the reinforcements A and are moved to the sides of the joint reinforcements 3 assembled into the reinforcements A, and they are bound with the reinforcements B as they are, without moving the joint reinforcements 3, and the reinforcements B and the reinforcements A are assembled with each other. As a result, assembling can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for anchoring pre-assembled wall reinforcing bars to pre-assembled column reinforcing bars.

(Conventional technology) Conventionally, when constructing using the wall reinforcing bar pre-assembly method, the joint between a column and a wall is created by connecting joint bars (b) to (C) when pre-assembling wall reinforcing bars (a).
8). After hanging the wall reinforcing bars (a), remove the temporary bundling of the joint reinforcing bars (b) and insert them into the column reinforcing bars ((1). It is common practice to temporarily tie the reinforcing bars together again.

(Problems to be Solved by the Invention) In the conventional construction method, the joint bars are temporarily untied from the wall reinforcing bars, pulled into the column reinforcing bars, and tied again, which takes time. was suspended, operational efficiency was poor, and labor was wasted.

Furthermore, there is a risk of the joint line body falling during the movement and binding work of the joint line, which poses a problem in terms of work safety.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to provide a method for assembling pre-assembled wall reinforcing bars with improved workability and safety. be.

(Means for Solving the Problems) In order to achieve the above object, according to the method for assembling pre-assembled wall reinforcing bars according to the present invention, joint Insert the reinforcing bars at the same pitch as the wall reinforcing bars and with their tips protruding from the column reinforcing bars, and after setting the joint reinforcing bars in place, suspend the preassembled wall reinforcing bars and insert them laterally toward the column reinforcing bars. It is configured to be moved and tied to the spliced reinforcing bar.

(Function) According to the present invention, as described above, when pre-assembling column reinforcing bars, joint reinforcements are inserted into the space between the main reinforcement of the column reinforcement and the hoop reinforcement at the same pitch as the wall reinforcement, and The tip of the pre-assembled column reinforcing bar is made to protrude from the column reinforcing bar, and the pre-assembled column reinforcing bar with the joint reinforcing bar incorporated therein is erected at a predetermined position.Then, the pre-assembled wall reinforcing bar is suspended in a position opposite to the pre-assembled column reinforcing bar, and the joint reinforcing bar is installed at a predetermined position. Assemble the pre-assembled wall reinforcing bars and the pre-assembled column reinforcing bars by moving them laterally to the reinforcing steel side and tying the protruding parts of the joint bars incorporated in the pre-assembled column reinforcing bars and the pre-assembled wall reinforcing bars at the same pitch as the wall reinforcing bars. It is something.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Main reinforcement in a pre-assembled column reinforcing bar placed horizontally on a frame (1
) and the hoop reinforcement (2), insert the joint reinforcement (3) at the same pitch as the pre-assembled wall reinforcing bars and so that the tips protrude from the pre-assembled wall reinforcing bars (see Figures 2 and 2). (See Figure 3) Erect as shown in the direction of the second arrow X and arrow y in Figure 3.

Figure 4 shows the preassembled column reinforcing bars erected in this way.

In this case, there is no danger of the joint bar (3) falling even if it is not tied to the previously assembled column reinforcing bar.

After the pre-assembled column reinforcing bars are erected at the predetermined positions, the pre-assembled wall reinforcing bars +81 are hung in positions facing the same column reinforcing bars as shown by arrow 2 in FIG. 5, and as shown by arrow U in FIG. 6. It moves laterally to the joint oil side that has been incorporated into the pre-assembled column reinforcing bar (2), without moving the joint bar (3) that protrudes from the column reinforcing bar.
As it is, bundle the pre-assembled wall reinforcing bars (81) and assemble the pre-assembled wall reinforcing bars (Bl) and the pre-assembled reinforcing bar holes. (Figures 1 and 6
(See figure) Note that (4) in the figure is the binding part of the joint bar (3).

(Effects of the Invention) According to the present invention, as described above, in the space between the main reinforcing bars and the hoop reinforcing bars of the previous column reinforcing bars, the connecting bars are placed at the same pitch as the wall reinforcing bars and whose tips are closer to the column reinforcing bars without tying them together. The pre-assembled column reinforcing bars are inserted so as to protrude, and the pre-assembled column reinforcing bars with the splicing bars incorporated therein are set upright at a predetermined position, and then the pre-assembled wall reinforcing bars are suspended and moved laterally to the splicing oil side, and the pre-assembled column reinforcing bars and the above-mentioned column reinforcing bars are suspended. Since the pre-assembled wall reinforcing bars and the pre-assembled column reinforcing bars are assembled by tying together the joint bars, the work of temporarily tying and pulling out the joint bars is reduced compared to the conventional method of assembling the joint bars into the wall reinforcing bars. It can be omitted, and there is no risk of dropping the splicing line during the same operation.
It improves work safety.
