More specifically, the present invention relates to a reinforcing bar binding tool for binding a plurality of reinforcing bars that are embedded in concrete to form a reinforced concrete structure.

[0002]

2. Description of the Related Art As a conventional binding tool for reinforcing bars, for example, Japanese Unexamined Patent Publication No.
The thing described in the 001-164700 publication is known. Hereinafter, a conventional reinforcing bar binding tool will be described with reference to the drawings. FIG. 11 is a perspective view for explaining an example of a conventional reinforcing bar binding tool. The reinforcing bar binding tool 101 includes a first grip portion 102 and a second grip portion 103, and the first grip portion is substantially parallel. It has a first base portion 104 having both side edges and a first side portion 105 standing upright from both side edges of the first base portion and opposed to each other, and the second grip portion has a second base portion 106 having substantially parallel side edges and a second Second side parts 10 standing upright from both side edges of the base part and facing each other
Have 7. Further, the first grip portion and the second grip portion are fixed to the back surface of the first base portion and the back surface of the second base portion so as to grip the reinforcing bars substantially orthogonally.

FIG. 12 is a perspective view for explaining another example of the conventional binding tool for reinforcing bars, which includes a first grip portion and a second grip portion.
The rear surface of the first substrate and the rear surface of the second substrate are fixed to the grip portion so as to grip the reinforcing bars substantially in parallel.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.

FIG. 1 is a perspective view for explaining an example of a reinforcing bar binding tool to which the present invention is applied. The reinforcing bar binding tool 1 shown here is made of a metal material having a certain elastic region,
It has the 1st holding part 2 which holds the 1st reinforcing bar, and the 2nd holding part 3 which holds the 2nd reinforcing bar so that it may intersect perpendicularly with the 1st reinforcing bar.

Here, the first gripping portion has a cylindrical shape having the first opening portion 4, and the inner surface of the first gripping portion facing the first reinforcing bar is placed in concrete as shown in FIG. Engaging portions 7 that engage with the ribs 6 formed on the reinforcing bars 5 are formed to increase the area of adhesion to the concrete when embedded and to increase the pull-out strength. The width of the first opening indicated by reference character A in FIG. 1 is smaller than the diameter of the first reinforcing bar.

Further, the second grip portion has a cylindrical shape having the second opening portion 8, and an engaging portion is formed on the inner side surface of the second grip portion facing the second reinforcing bar, similarly to the first grip portion. Has been done.
The second opening is formed so as to face the same direction as the first opening, and the width of the second opening indicated by reference character B in FIG. 1 is smaller than the diameter of the second reinforcing bar. .

Here, the first grip portion is sufficient as long as it can grip the first rebar, and does not necessarily have a cylindrical shape, and may have any shape as long as it can grip the first rebar. A flat plate-shaped first base portion 9 having parallel side edges as shown in FIG. 3 is formed with flat plate-shaped first side wall portions 10 standing from both side edges of the first base portion, and FIG. It may be a U-shape in which a first base portion and a first side wall portion having a semicircular shape as shown are formed. The width of the first opening is formed smaller than the diameter of the first reinforcing bar by the convex portion 11 formed on the first grip portion. Further, the second grip portion is sufficient as long as it can grip the second reinforcing bar, and does not necessarily have a cylindrical shape, and may have any shape as long as it can grip the second reinforcing bar, for example, as shown in FIG. A flat plate-shaped second base portion 12 having parallel parallel side edges and a flat plate-shaped second side wall portion 13 standing upright from both side edges of the second base portion, as shown in FIG. It may be a shape in which a second side wall portion having a dogleg shape is formed on the second base portion having a flat plate shape having two side edges, which are respectively erected from both side edges of the second base portion. The width of the second opening is formed smaller than the diameter of the second reinforcing bar by the convex portion formed on the second grip portion.

Further, the engaging portions formed on the inner surfaces of the first grip portion and the second grip portion include the first reinforcing bar, the first grip portion and the second grip portion.
Is for strengthening the engagement between the reinforcing bar and the second grip portion, and is not necessarily indispensable for binding the reinforcing bar, but the engaging portion is required to enable the strong binding of the reinforcing bar. It is preferably formed. Further, the width of the first opening is formed to be smaller than the diameter of the first reinforcing bar.
Is for strengthening the engagement between the reinforcing bar and the first grip portion, and in binding the reinforcing bar, the width of the first opening must be formed smaller than the diameter of the first reinforcing bar. However, the width of the first opening is preferably smaller than the diameter of the first reinforcing bar so that the reinforcing bars can be tightly bound. Similarly, the width of the second opening is smaller than the diameter of the second rebar because the second rebar and the second rebar
The purpose of this is to strengthen the engagement with the grip of the reinforcing bar, and when binding the reinforcing bars, the width of the second opening need not necessarily be formed smaller than the diameter of the second reinforcing bar.
The width of the 2nd opening is the 2nd to enable the strong binding of the reinforcing bars.
It is preferable that the diameter is smaller than the diameter of the reinforcing bar.

Here, when the reinforcing bars are bound by using an example of the reinforcing bar binding device to which the present invention is constructed as described above, for example, when the reinforcing bars are bound at the longitudinal and lateral d intervals, first, As shown in FIG. 5 (a), the outer frame of the rebar to be assembled is formed, and the rebar forming the outer frame is marked 14 as a mark at intervals of d. Then, the reinforcing bars are arranged at vertical and horizontal d intervals as shown in FIG. 5 (b) based on the markings given at every d intervals, and then the reinforcing bar binding tools are provided at the intersections of the reinforcing bars in FIG. 5 (b).
By mounting from the vertical direction indicated by the middle symbol C, FIG.
As shown in (c), the reinforcing bars are bound at vertical and horizontal intervals d. That is, after the reinforcing bars are assembled at vertical and horizontal intervals d, the second reinforcing bars are elastically deformed by pressing the reinforcing bar binding tool against the intersecting portions of the reinforcing bars, and the second reinforcing bars are sandwiched, and the second reinforcing bars are gripped. Then, a force is applied vertically upward to the first reinforcing bar by the second reinforcing bar so that the intersecting reinforcing bars are bound as shown in FIG.

In the reinforcing bar binding tool to which the present invention is applied, since the reinforcing bar binding tool can be assembled after the reinforcing bars have been assembled at a predetermined interval, the reinforcing bars can be easily measured only by measuring the minimum necessary interval. It can be assembled. That is, it is possible to measure the predetermined intervals only for the outermost reinforcing bars, and at other points, the reinforcing bars can be bound at predetermined intervals simply by attaching the reinforcing bar binding tools at the points where the reinforcing bars intersect, thus improving work efficiency. Can be expected to improve.
