Description

[Detailed description of the invention] This invention relates to a binding tool for various types of reinforced reinforcing bars.
In particular, it relates to a binding tool that can bind stirrups and lower main reinforcements with one touch.

The various types of reinforcing bars placed on walls, columns, beams, etc. are designed to handle the load, deflection stress, principal tensile stress, etc. applied to them. Therefore, unless it is constructed according to the design, the desired strength and rigidity will not be obtained, and problems will also arise in connection with equipment piping, etc. Therefore, even when concrete is poured, it is naturally necessary to maintain the above-mentioned reinforcement positions, and for this purpose, various types of reinforcing bars are generally tied together at their respective intersections. Conventionally, this binding has generally been done using a hand tool with a thin wire binding wire, but this is a very troublesome work and has poor workability. In particular, in the case of beams, the higher the effective strength, the more difficult it is to tie the stirrups and lower main reinforcements together in normal tying work, and in many cases the tying work is carried out lying on one's stomach, and in some cases, the tying is carried out in a temporary frame. The work was difficult and the work efficiency was extremely low.

In addition, the following ideas can be cited as technical documents similar to the present invention. That is, Utsukai Showa 47-21423
There is a rebar fixing device of No.

However, this fixture is made of metal and has a structure in which a hook portion is provided on one side of the main body portion and a bent portion is provided on the other side.

As shown in FIG. 6, the main body is not attached in the longitudinal direction of the reinforcing bars when the reinforcing bars are tied together.

Therefore, the tightness of the bundled reinforcing bars is weak;
When concrete is poured, there is a risk that the concrete will get between the reinforcing bars and the main body, causing the fixing device to come off.

In view of the above, it is an object of the present invention to provide a reinforcing bar binding tool that can securely bind various reinforcing bars with one touch.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes a main body part 2 which is made of a stretchable member such as rubber or plastic that can be expanded/contracted or twisted, and which is oriented in a linear direction, and which is both ends of this main body part 2 and which is oriented in the linear direction of this main body part 2. A binding device consisting of band-shaped or rod-shaped hook portions 3, 3' made of an elastic member such as rubber or plastic that can accommodate expansion/contraction or twisting and located in the same direction with the axis as the center. Both hook parts 3 of 1,
3' is a reinforcing material such as metal or hard plastic 4,
4', and the two hook portions 3, 3' are configured to curve in the same direction. The curved surfaces of both hook portions 3, 3' are adapted to match the outer peripheral surface of a general reinforcing bar having a diameter of 10 to 13 mm. If a suitable number of barbs 5 are provided on the inside of the curved surface as shown in FIG.
This is advantageous since it is less likely that 3' will come off.

When attempting to bind, for example, the stirrup 6 and the lower main reinforcement 7 using the binding tool 1 configured in this way, use a hook having a hook as shown in FIG. Hang one hook part 3 of the stirrup 1 on the stirrup 6, for example, on the raised part 6' at the corner of the stirrup 6, and on the horizontal part 6'' at the middle part. Stretch the main body part 2 to some extent and attach it strongly to the reinforcing bar, for example in the longitudinal direction, so that the other hook part 3'
are hooked onto the horizontal portion 6'' of the stirrup 6, as shown in FIG. '', the binding is completed through the reaction force of the tensioned main body part 2 of the stirrup 6 and the lower main reinforcement 7, and this binding is quite strong. 8 in the figure For example, in the temporary frame of the beam, 9 is a spacer.

As described in detail above, the present invention consists of a main body made of an elastic member such as rubber that can be expanded/contracted or twisted, a main body oriented in a straight direction, and a main body This is a reinforcing bar binding tool that has hooks located at both ends and located in the same direction around the axis of the main body.

Therefore, it has the following effects.

That is, when tying the reinforcing bars, the main body part is pulled and attached strongly to the longitudinal outer peripheral surface of the reinforcing bars to lock them, which has the effect of improving the degree of tightening of the tying reinforcing bars.

Further, the present invention is configured to bind the body portion through a reaction force to the tensile force of the main body portion.

Therefore, the strength of the binding can be improved, and through this effect, when pouring concrete,
This has the effect that the binding will not come loose and the reinforcement will be positioned as designed. In addition, regardless of the diameter of reinforcing steel, it can be used within a certain range,
A strong binding state is achieved as well as so-called improved versatility.

Furthermore, in the present invention, when locking the bundled portion of reinforcing bars, first, one hook portion is locked, and then the main body portion is twisted in the longitudinal direction or orthogonal direction of the reinforcing bars and is in a tensile state, and the other hook portion is locked. It has a structure that locks and binds the hook part.

Therefore, it is possible to deal with various bundling situations, such as bundling reinforcing bars at plane intersections, and bundling reinforcing bars in different directions (specifically, the state of the corners of stirrups in Figures 4 or 5). be effective and extremely beneficial.
In addition, the binding strength at that time is sufficiently guaranteed. Furthermore, if a hook having a hook is used, even when the effective strength of the beam is high, the work of lying on one's stomach as required in the past is eliminated, which helps to simplify and speed up the work. Furthermore, since the hook portions are curved in the same direction, it has many practical effects such as easy locking of the hook portions.
