Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a wall insert bar.

[0002]

2. Description of the Related Art When constructing a wall of a reinforced concrete building, before the slab concrete is placed, after marking is completed, a bar is attached on the beam to integrate the wall and the slab. ing. However, since the wall insertion bar projects from the slab, it is dangerous because it collides with people and objects. Conventionally, as a method of curing it, a commercially available curing cap is attached to the head of each bar or a single pipe or A method has been used in which a lumber is attached along the head of a bar, a hook is attached to the head of the bar, or each bar is bent in a U shape in advance.

[0003]

The above-mentioned conventional method requires a great deal of labor and time, and since the reinforcing bar itself is also arranged in one line, the accuracy of the position of the reinforcing bar is difficult. The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to improve the accuracy of the position of the reinforcing bar by achieving curing of the reinforcing bar and labor saving of the mounting. The point is to provide a method of attaching the muscles.

[0004]

In order to achieve the above-mentioned object, according to the method of attaching a reinforcing bar of a wall according to the present invention, both side leg pieces of a plurality of inverted U-shaped reinforcing bars formed by bending the reinforcing bars. The wall inserts, which are connected to each other with reinforcing bars, are erected in the wall attachment portion of the concrete slab.

[0005]

According to the present invention, as described above, bent rebars are bent to produce inverted U-shaped rebars, and the leg pieces on both sides of each of the thus-fabricated inverted U-shaped rebars are assembled. The reinforced concrete wall with high strength and rigidity is constructed by connecting the reinforced concrete, and the reinforced concrete wall is erected at the wall mounting position on the slab concrete before the concrete is placed.

Therefore, since the wall insert bar is simply, quickly and accurately arranged at a predetermined position and the projecting portion is bent in a U-shape, the danger to a person or an object is prevented. Since it has high strength and rigidity, it is unlikely to be displaced or deformed by concrete pouring pressure.

[0007]

The present invention will be described below with reference to the illustrated embodiments. 1 is an inverted U-shaped rebar formed by bending a rod-shaped reinforcing bar, and a plurality of the same inverted U-shaped rebars 1 are arranged in the front-rear direction to form a multi-tiered wall reinforcement on both leg pieces 1a, 1a of each rebar 1. They are connected by horizontal connecting rebars 2 having the same diameter by welding, and horizontal rebars 3 are welded between the opposite side leg pieces 1a, 1a of the inverted U-shaped rebars 1 at the front and rear ends. To be manufactured in advance.

Thus, the beam C in the concrete slab B
When the bar A is inserted at the position of the wall portion to be mounted on the upper part, the receiving bar 3 is supported by the beam main bar 4, and the bar A is set at a predetermined position. After that, the slab B and the beam C
The concrete will be poured. In the illustrated embodiment, as described above, a plurality of inverted U-shaped rebars 1 are arranged side by side in the front-rear direction, and both leg pieces 1a of each rebar 1 are connected to each other by rebars 2 to form a wall insert A. Therefore, by arranging the same wall reinforcement A at a predetermined position, a large number of reinforcements can be accurately arranged at one time. In addition, since each rebar forming the wall insert muscle A is bent in a U-shape, the wall insert bar A can be set without damaging a person or damaging an object by the protrusion of the bar insert. There is no need to cure as in the past.

Further, since the leg pieces 1a of the respective inverted U-shaped rebars 1 constituting the wall insertion rebar A are connected by the connecting rebars 2, the strength and rigidity are great and they are displaced or deformed by the pouring concrete pressure or the like. There is no fear of doing so, and it is held in place. Figure 3
Shows a case of a single bar arrangement, in which the above-mentioned inverted U-shaped rebars 1 are arranged on the same vertical plane, and both side leg pieces 1a, 1a are connected by a connecting bar 2 by welding.

[0010]

As described above, according to the present invention, a plurality of inverted U-shaped reinforcing bars are provided without arranging a single wall insert bar to be installed in the wall attachment portion of the concrete slab as in the conventional case. By making a wall insert that connects the leg pieces of each side with connecting bars, and by arranging the wall inserts, labor of installing the bar is improved, the accuracy of the mounting position is improved, and the strength of the wall bar is further increased. Since the rigidity is high, there is no fear of deformation and displacement due to concrete pouring pressure or the like. Further, since the protruding portion from the slab in the wall insertion muscle is bent in a U-shape, there is no possibility of injuring a person or damaging an object, and labor saving of the reinforcement muscle can be achieved.
