Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a main bar binding tool that easily and firmly binds the intersections of main bars such as vertical bars and horizontal bars embedded in a concrete structure.

[0002]

[Prior art]

 Deformed bars are generally used for various main reinforcements such as column main reinforcements, beam main reinforcements, wall main reinforcements embedded in concrete structures, and multiple main reinforcements are used to obtain a shape suitable for the structure and a predetermined strength. Using a book, the vertical and horizontal bars are laid out in a predetermined shape, and the intersections of the main bars are integrated by bundling or electric welding, or by using a resin band. After bundling using it, concrete is poured, and all the main bars, including the various reinforcing bars and the binding part of the main bars by the binding number lines, are covered with a predetermined concrete thickness.

[0003]

[Problems to be solved by the device]

 However, as various main bars, deformed bars are widely used because they improve the adhesion to coated concrete depending on the strength and other conditions. For this reason, bundling with an annealed iron wire (number wire) with a diameter of 0.9 mm or more requires labor, the binding force is not constant depending on the operator, and when binding by electric welding, the main bar is magnetized and constructed during welding. There is a drawback that affects OA equipment installed in the rear building. Furthermore, if the main reinforcing bar itself is not a reinforcing bar and a special resin-made main reinforcing bar is used so as not to affect the OA equipment, it is not possible to perform binding by means of a numbered wire, and binding of such a main bar requires additional labor. Further, in the conventional binding method, a great deal of work is required to change the main bars due to design changes and the like.

In the present invention, the binding of the main bars and the release of the binding, if necessary, can be performed easily, quickly and firmly without using welding or binding wire, and the main bars are tightly tied even if the diameters of the main bars are uneven. The purpose is to prevent loosening.

[0005]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above-mentioned object.The outer peripheral surface of a vertical streak is formed into a bendable arc shape so as to be held according to its diameter, and one end has a locking piece at the other end. Both sides of the horizontal bar receiving piece that holds the horizontal bar that is arranged so as to intersect with the vertical bar in a direction orthogonal to the vertical bar The gist of the present invention is that they are integrally provided through the respective support pieces, and that the horizontal bar holding portion is formed in a U-shape for fitting and supporting the horizontal bar.

[0006]

[Work]

 On the both sides of the U-shaped horizontal bar receiving piece that is made of synthetic resin and fits and supports the horizontal bar that crosses the vertical bar, hold the vertical bar that is arranged so as to be in contact with the horizontal bar and cross each other. Band-shaped arc-shaped vertical strip embracing piece is integrally formed, and the vertical strip embracing piece is in the form of a band, with a locking piece at one end and a plurality of engaging pieces at the other end. Is formed so that the longitudinal muscles are held according to their diameters, so that the binding of the main muscles to be crossed can be achieved by fitting the proposed binding tool to the U-shaped holding portion at the horizontal muscle of the main muscle crossing point. However, the band-shaped horizontal bar holding piece is wound around the horizontal bar, and the locking pieces and engaging pieces at both ends are locked to each other according to the diameter, so even if the diameter of the main bar is different, it can be easily and firmly bound. , It is also possible to remove the binding if necessary. In addition, since the binding tool is made of synthetic resin, it does not magnetize the main bar unlike in electric welding.
