Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar assembly method for assembling reinforcing bars in the work of constructing a structure made of reinforced concrete.

[0002]

2. Description of the Related Art Pillars and beams of reinforced concrete structures,
When forming walls, floors, ceilings, etc., after arranging in the formwork, concrete is placed here and hardened. At this time, the reinforcing bars are positioned, and the reinforcing bars are fixed to each other or with the binding wires so that the reinforcing bars do not move during concrete driving.

[0003]

However, in order to hold the reinforcing bars by using the binding wires, it is necessary to manually fix the main bars to each other or the auxiliary bars and each of the main bars by the binding wires. Therefore, in the conventional method, a great deal of labor and time are required to bind the binding wires for holding the reinforcing bars, and in holding the reinforcing bars using the binding wires, the position of the auxiliary bars tends to change depending on the operator. However, it is relatively difficult to fix the auxiliary muscles in a correct position, and there is a problem that a skilled worker is required. An object of the present invention is to provide a bar arrangement method in which a binding operation can be easily performed in a short time, auxiliary muscles are accurately arranged on a main bar at a predetermined interval, and moreover, regardless of an expert, anyone can perform the operation without error.

[0004]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A plurality of engaging portions of auxiliary muscles are provided at predetermined intervals in the longitudinal direction of the long material, and the engaging portions of the same long material are provided. A plurality of auxiliary muscles looped in between are attached to produce an auxiliary muscle connected body, the auxiliary muscle connected body is inserted into the main muscle, and the main muscle and the auxiliary muscle connected body are connected at required positions 2) Attaching a looped auxiliary bar to the main bar, arranging a long member with locking parts at predetermined intervals in the longitudinal direction of the main bar, engaging the auxiliary bar with the locking part of the long bar, Reinforcing method characterized by connecting timbers at required places to perform rebar 3) Engage a plurality of notches provided in a plate material having an L-shaped cross section with a main bar in which an auxiliary muscle connecting body is inserted The reinforcing bar arrangement method according to 1) and 2) above, in which the reinforcing bar is assembled by holding the main bar with a plurality of plate materials.

[0005]

A plurality of looped auxiliary muscles for assisting the main muscles of the reinforcing bar are attached to the engaging portions provided on one or a plurality of long members to form an auxiliary muscle connected body. After inserting the auxiliary muscle connected body so as to cover the main muscle, the main muscle and the auxiliary muscle connected body are connected using a connecting means such as a binding wire. As a result, anyone can definitely attach the auxiliary muscle to the main muscle at a predetermined interval. After that, the cross section L is added to the main muscle into which the auxiliary muscle connector is inserted.
By engaging a plurality of notches provided in the character-shaped plate material, the space between the main bars is maintained and the space between the main bars and the form is set to a predetermined position.
