Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to anchoring bars embedded in foundation concrete when constructing a foundation.
[0002]
[Prior art]
In general, when constructing foundations for residential buildings, it is common practice to place anchors in the framework framed in the field, place concrete, and embed anchors in the foundation concrete. .
[0003]
Conventionally, as shown in FIG. 5, the fixing line a includes a bent portion b bent in a substantially U shape, and a long straight portion c extending from the bent portion b and parallel to each other. A combination of the formed U-shaped lines d is known.
[0004]
That is, the fixing line a shifts the pair of U-shaped lines d in the width direction so that the straight line parts c of the other U-shaped lines d are located between the parallel line parts c of the U-shaped line d. The straight portions c of the U-shaped lines d are fixed by welding to a fixed line e arranged in a direction perpendicular to the straight lines c.
[0005]
[Problems to be solved by the invention]
However, since the conventional fixing bar a is bulky with the U-shaped bar d being doubled, when used as a foundation main bar, the foundation has to be made bulky, and the amount of concrete is also large. This increases the cost and disadvantages of the economy.
[0006]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fixing line that can make the arrangement of the bar arrangement compact.
[0007]
[Means for Solving the Problems]
The fixing bar of the present invention for solving the above-mentioned problem is a fixing bar embedded in foundation concrete, a bent part bent in a substantially U shape, and extended from the bent part and parallel to each other. The straight line portions of the pair of U-shaped lines are the same so that the straight line parts of the other U-shaped lines are located between the straight line parts of the U-shaped lines. The bent portions are alternately arranged side by side on the plane, and the bent portions are bent with respect to the straight portions so that the bent portions do not buffer each other in this side-by-side state.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 shows an outline of the entire configuration of the fixing muscle 1, and FIG. 2 shows a construction state of the identified reinforcement 1.
[0010]
That is, the fixing line 1 is configured by combining the U-shaped line 2.
[0011]
The U-shaped bar 2 is formed by bending a reinforcing bar, and linear portions 22 that are parallel to each other are extended from a bent part 21 that is bent in a substantially U-shape.
[0012]
As shown in FIG. 3, the U-shaped line 2 has a bent portion 21 bent with respect to the straight portion 22, and the front end of the bent portion 21 is arranged with the parallel straight portions 22 arranged on the same plane A. At least a distance corresponding to the radius R of the U-shaped line 2 is lifted from the plane A.
[0013]
This U-shaped line 2 is a straight line in which the pair of U-shaped lines 2 are shifted in the width direction so that the straight line parts 22 of the other U-shaped lines 2 are located between the parallel straight line parts 22 of the U-shaped line 2. The portions 22 are alternately arranged side by side on the same plane A. At this time, as shown in FIG. 1B, each U-shaped line 2 is bent in a direction in which the bent portions 21 are separated from the straight portions 22 so that the bent portions 21 do not buffer each other. Use as a combination.
[0014]
In this state, the U-shaped bars 2 are fixed by welding to the fixed bars 3 in which the respective straight line portions 22 are arranged in a direction perpendicular to the straight line portions 22.
[0015]
The fixing line 1 configured in this way is not bulky in the height direction because the straight portions 22 of the U-shaped line 2 are alternately arranged side by side on the same plane A. Therefore, as shown in FIG. 2, the anchoring bar 1 can be made compact, so that the foundation 4 constituted by embedding the anchoring bar 1 in the concrete can be made compact and workable. Improvements can be achieved.
[0016]
In the present embodiment, the fixing line 1 is configured by combining a pair of U-shaped lines 2 in which the bent part 21 is bent with respect to the straight line part 22. For example, as shown in FIG. The U-shaped line 2 a is not bent at the bent part 21 with respect to the straight line part 22, and the other U-shaped line 2 b may be formed by bending the bent part 21 with respect to the straight line part 22. Good. However, in this case, the parallel straight portions 22 are arranged on the same plane so that the U-shaped line 2b in which the bent portion 21 is bent with respect to the straight portion 22 does not buffer the bent portion 21 of the other U-shaped line 2a. In the state of being placed on A, the tip of the bent portion 21 must be lifted from this plane A by a distance corresponding to at least the diameter D of the U-shaped line 2a.
[0017]
【The invention's effect】
As described above, according to the present invention, since the bent portions are bent with respect to the straight portion so that the bent portions do not buffer each other in a side-by-side state, the straight portions of the pair of U-shaped lines are flush with each other. It can be alternated side by side above. Therefore, it is possible to prevent the reinforcing bars from being multi-staged and to make the arrangement of the reinforcing bars compact, so that the basic concrete can be made compact and the workability can be improved.
