2. Description of the Related Art In order to construct a wall of a concrete structure, prior to casting concrete, a plurality of vertical bars are provided with a plurality of horizontal bars and a reinforcing bar fixed with a wire or the like. assemble. At this time, it is necessary that the interval between the adjacent horizontal streaks be kept constant.However, in order to fix the horizontal streaks at a constant interval, the vertical streaks are marked in advance, and the worker fixes them based on the marks. I needed to go. In the actual work, first, both ends of the horizontal streak are fixed to the vertical streaks at predetermined positions, and then the intermediate portion of the horizontal streak is sequentially fixed to the vertical streaks.
However, the operation of fixing both ends of the horizontal streak to the vertical streak requires an operator holding the horizontal streak and an operator fixing the horizontal streak with a wire or the like, and the working efficiency is not good. In addition, there is also a problem that an increase in the dimensions (length and thickness) of the horizontal streaks increases a physical burden on an operator holding the horizontal streaks.

Under such circumstances, various jigs for arranging the horizontal streaks for temporarily holding the horizontal streaks at predetermined positions have been proposed. For example, JP-A-8-146046 and JP-A-8-311
391, JP-A-7-208660 and the like.
By using such a jig for arranging the horizontal streaks, the temporarily held horizontal streaks can be sequentially fixed to the vertical streaks by using a wire or by welding or the like, and compared with a case where no jig is used. If this is the case, workability will be significantly improved. However, after arranging the horizontal streak, it is necessary to remove the jig and to fix the horizontal streak, and there is still room for improvement in work efficiency.

There is also known a horizontal bar arrangement supporter which can arrange a bar without using a horizontal bar arrangement jig which needs to be detached (Japanese Patent Laid-Open No. 6-237639). However, even when this support is used, the horizontal streak and the support have to be fixed using a wire or fixed by welding or the like. Further, the jig for arranging the transverse streaks does not have a function of preventing the temporarily arranged transverse streaks from dropping, and there is a risk that the streaks before fixing may fall during the temporary staging.

In the reinforcing bar according to the present invention, it is preferable that the distance between the protrusion 4 or 14 and the vertical bar 2 or 12 is substantially equal to the diameter of the horizontal bar to be held. By doing so, the arranged horizontal streaks are also fixed at the same time as the arrangement, so that the position of the horizontal streaks can be fixed without fine adjustment before fixing work, and in some cases, the fixed streak can be fixed. There is an advantage that work is not required.

Further, the distance between the tip of the projection 4 or 14 and the longitudinal streak 2 or 12 is made smaller than the distance between the base of the protrusion 4 or 14 and the longitudinal streak 2 or 12. Can be effectively prevented. In particular, the distance between the tip of the protrusion 4 or 14 and the longitudinal streak 2 or 12 can be inserted into the horizontal streak, but by making the distance smaller than the diameter of the held horizontal streak, the arranged horizontal streak can be removed from the arm. Separation can be effectively prevented, and the horizontal streak can be securely fixed to the vertical streak.

Further, in the reinforcing bar of the present invention, for example, as shown in FIG. 1, it is preferable that one end 5 of the vertical bar has a hook shape. By having such a structure, there is an advantage that positioning can be easily performed by hooking a hook portion on the already-arranged reinforcing bar for beams. Further, the direction of the hook portion and the direction of the arm can be appropriately determined in consideration of the positional relationship between the beam and the wall constructed using the reinforcing bar of the present invention. Further, the distance B between the end 5 and the protrusion 4 adjacent to the end 5 can be appropriately determined in consideration of the distance from the beam to the first horizontal streak.
