Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reinforcing bar arrangement method and a reinforcing bar connector for binding intersections of reinforcing bars laid out in a substantially orthogonal manner, and further relates to relates to a coupling tool that can also erect spacers for slab reinforcements.

[Prior Art] As is well known, in reinforced concrete structures, prior to concrete pouring, reinforcing bars are laid out in a mesh pattern by overlapping them in a substantially orthogonal manner, and the overlapped intersections are laid out during concrete pouring. It is tied together to prevent it from getting disturbed. Such binding is generally carried out by using wire and sequentially determining the binding position one by one.

[Problem to be solved by the invention] By the way, the above-mentioned binding using wire has poor workability;
It also requires skill, which increases construction costs.

Furthermore, in the past, reinforcement was arranged while determining the bundling position, further reducing work efficiency.

In addition, the wire used for binding is simply buried and has poor usability. Spacers cannot be installed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for arranging reinforcing bars and a reinforcing bar coupler that eliminate the above-mentioned conventional drawbacks. More specifically, the objective is to provide a reinforcement arrangement method that allows for easy and reliable tying work when arranging reinforcement, and also enables the tying position to be accurately determined and arranged without using a jig or the like. .

Another object of the invention is to provide a reinforcing bar coupler that can reliably carry out the method invention described above.

[Means for Solving the Problems] According to the present invention, when arranging a plurality of reinforcing bars in an intersecting manner and arranging the reinforcing bars by tying the intersections together, a main body is used as a binding tool to cooperate with the main body. The main body has a curved part that fits each of the intersecting reinforcing bars, and is connected at predetermined intervals by spacing members. The main body is positioned using a spacer, and then the auxiliary members of the main body are welded and bound together.

Further, according to the present invention, a coupling device for binding the intersections of reinforcing bars arranged in a substantially orthogonal overlapping state is composed of a main body and an auxiliary member that cooperates with the main body, and the main body is The auxiliary member is welded to the main body, and the auxiliary member is welded to the main body.

[Operations] Therefore, when arranging reinforcing bars in which a plurality of reinforcing bars are arranged in an intersecting manner, first tie the intersections of the reinforcing bars at appropriate positions using a coupler. For binding, the curved portions of the main body are fitted to the respective reinforcing bars arranged in a crosswise pattern, an auxiliary member is applied to the main body, and the two are integrated by welding.

This will complete the binding. Since there is a spacing material attached to the main body, use this spacing material to determine the position of the next intersection to be bound, and then bind in the same way. After that, the pieces are tied while positioning them in sequence. Also, if necessary, spacers for slab reinforcement are attached by welding to the top surface of the main body after binding.

[Examples] Examples of the present invention will be described below. 1 and 2 are diagrams showing the first embodiment, and referring to the figures, the reinforcing bar coupler C is composed of a board-like member. That is, the reinforcing bars A and B are arranged in advance so as to intersect in a substantially orthogonal manner. This intersection is bound by a coupling tool C, which consists of a main body 1 and an auxiliary member 10.

The main body consists of a first part 2 and a second part 3, the first part has a curved part 4 that fits into the reinforcing bar B, and the second part has a curved part 5 which fits into the reinforcing bar A. Since the reinforcing bars ASB are overlapped in a crosswise manner, these curved parts 4.5 are also formed so that their axes are perpendicular to each other, have a step corresponding to the diameter of the reinforcing bars, and have a predetermined height. These curved portions are formed at intervals of . The main body 1 is generally formed by press working or the like, and the plate thickness is not so thick, so that the step of the curved portion 4.5 can be added during the bundling operation.

A spacing member 6 is integrally provided in the main body 1, is provided in the first part 2 at right angles to the curved part 4, and in the second part 3 in the axial direction of the curved part 5, which are arranged in a predetermined direction. They are joined so that they are at intervals.

Next, a reinforcement method using the above-mentioned coupler C will be described.

For example, first, the intersections (A) shown in FIG. 1 are tied together. For binding, each curved part 4.5 of the main body 1 is connected to reinforcing bars B and A.
Then, the auxiliary member 10 is applied from below to the reinforcing bar A, and the flange portion 7 of the main body 1 and the auxiliary member 10 are welded at points 11 and 11. This completes the binding.

Binding at the intersection (b) can be performed in the same manner, but the positioning of the intersection is performed by the spacing member 6 integrally provided on the main body. That is, the reinforcing bars B are moved so that the spacing members are in a stretched state. This determines the location of the intersection, so tie it up in the same way. After that, the intersections are sequentially tied together to complete the reinforcement arrangement.

A second embodiment of the invention is shown in FIGS. 3 and 4. According to this embodiment, the spacing member 7 is further added,
The position of the intersection in the vertical and horizontal directions can be determined. That is, in the first portion 2 of the main body 1, a spacing member 7 is also provided in the axial direction of the curved portion 4, and the main body parts are interconnected in a mesh-like manner.

In this embodiment as well, binding reinforcement can be arranged in the same manner as in the above-mentioned embodiment, but according to this embodiment, the effect that the binding position can be determined both in the vertical and horizontal directions can be obtained.

[Effects of the Invention] According to the present invention, the coupling device is composed of a main body and an auxiliary member, and the main body has a curved portion that fits into the reinforcing bars, so that the main body is placed on the reinforcing bars and the auxiliary member is applied. It can be bundled just by welding.

In other words, the bundling work can be done without requiring any skill, and work efficiency at the work site is improved. In particular, according to the present invention, since the spacing members are integrally formed in the main body, the binding position is automatically determined, the reinforcement is not lopsided, and the reinforcement is balanced as a whole. I can do it.
