Description

[Detailed description of the device] [The purpose of the device]

(Industrial field of application) The present invention relates to a fixing structure for crossed reinforcing bars used to prevent crossed reinforcing bars from moving from a predetermined position when the reinforcing bars are embedded in a reinforced concrete building in a crossing state. is there. (Prior Art) In a conventional reinforced concrete building, when pouring concrete, various methods are used to prevent movement of the reinforcing bars arranged in a predetermined position in an intersecting state,
Among them, the intersecting portions of the crossed reinforcing bars were fixed and the reinforcing bars were embedded at a predetermined position in the concrete by the methods (1) to (3) described below. A method of manually fixing the intersections of reinforcing bars with wires at the construction site. A method of continuously fixing the intersections of reinforcing bars by spot welding at the factory. A method of fixing the intersection of reinforcing bars by arc welding at the construction site. (Problems to be solved by the device) However, in the above-mentioned method, since the crossing portions of the reinforcing bars are tied and fixed manually by using wire, the work efficiency is low and the construction cost is high. There was a problem that it was too much. Also, with the method of, since the work is performed in the factory, it is possible to mechanize and fix the intersection of the reinforcing bars with high work efficiency, but it is necessary to transport the fixed reinforcing bars from the factory to the construction site. Since it is inconvenient and requires large-scale mechanical equipment for installation at the construction site due to the heavy weight, there is a problem that the work is troublesome and the construction cost is increased. Furthermore, the method (1) has a problem that fixing the intersection of the reinforcing bars by arc welding or the like at the construction site requires more labor and construction cost than the work with the wire (1). Therefore, it has been desired to fix the intersection of the reinforcing bars by an easy and quick work at the construction site to reduce the construction cost. (Purpose of the Invention) Therefore, the present invention has been made by paying attention to the above-mentioned conventional problems, and it is possible to fix the intersecting portion of the intersecting reinforcing bars by a simple work and reduce the construction cost required for one place. It is an object of the present invention to provide a fixing structure for crossed reinforcing bars that is made possible.

[Constitution of device]

(Means for Solving the Problems) According to the fixing structure of the crossed reinforcing bars according to the present invention for achieving the above-mentioned object, the crossed reinforcing bars are superposed in a diagonal direction at the intersections of the crossed reinforcing bars. A belt-shaped clip provided with polymerized pieces for bonding the polymerized portions to each other by electric welding is wound around both ends of the polymerized pieces to be polymerized in a palm-like shape. It is characterized in that the current-carrying surfaces are electrically weld-bonded to each other. (Example) Hereinafter, this invention is demonstrated based on drawing. 1 to 3 are views showing an embodiment of a fixing structure for crossed reinforcing bars according to the present invention, and FIG. 1 is a perspective view showing a fixing structure for vertically intersecting reinforcing bars. In FIG. 1, reference numeral 1 is a belt-like clip for winding and fixing the intersecting portions of the reinforcing bars 10 and 11 which intersect in the vertical direction shown in FIG. 2 in a diagonal direction. This belt-shaped clip 1 is a belt-shaped clip having polymerized pieces 2 and 3 which are bonded to each other by fusing the polymerized portions which are polymerized in a chiral pattern. As shown in FIG. After wrapping the diagonal direction at the intersection of the rebars 10 and 11, as shown in FIG. 3, the polymerization was performed in the state of being bent and formed at both ends of the clip 1 below the intersection. By contacting the pieces 2 and 3 with each other, they are polymerized in a palm-like shape, and the current-carrying surfaces formed by both outer surfaces of the polymerized portion of the polymerized pieces 2 and 3 which are polymerized in a palm-like shape are applied by the electrodes 20 and 21 for spot welding. While pressing, the electric current is supplied to the electrodes 20 and 21 to join the polymerized portions which are polymerized in a chiral pattern by welding by electric current, and the crossed portions of the reinforcing bars 10 and 11 are fixed by the belt-shaped clip 1. is there. Therefore, by winding the clip 1 around the intersecting portions of the reinforcing bars 10 and 11 and welding and welding the overlapping pieces 2 and 3, the intersecting portions of the reinforcing bars 10 and 11 are fixed. It becomes possible to prevent the reinforcing bars 10 and 11 from moving from a predetermined position when they are poured. Since the belt-shaped clip 1 described above can be obtained by cutting the clips 1 one by one by applying a slight external force by forming shallow grooves on both sides of the belt-shaped coil at predetermined intervals. , There are many reinforcing bars 1
It is possible to fix the intersection of 0 and 11 continuously.
Therefore, the belt-shaped clip 1 is, for example, rebar 10,11.
It is also suitable for fixing work by an unmanned work vehicle that automatically moves between the intersections and continuously fixes the intersections.

[Effect of device]

As described above, according to the fixing structure of the crossed reinforcing bars according to the present invention, in the diagonal direction of the crossed portions of the crossed reinforcing bars, the polymerized portions that polymerize in a chiral pattern are bonded to each other by current welding. A belt-shaped clip having both pieces at both ends is wound, and in the polymerized piece to be polymerized in a palm-like shape, they are electrically weld-bonded to each other at the current-carrying surfaces formed on both outer surfaces of the palm-shaped polymerized portion by the polymerized piece. With the above configuration, after winding the belt-shaped clip in the direction of the diagonal line at the intersection of the reinforcing bars, the work of simply welding the polymerized portions of the polymerized pieces provided at both ends of the belt-shaped clip by electric current welding, Since it is possible to fix the intersection, it is possible to obtain a remarkably excellent effect that the construction cost required for one place can be significantly reduced compared to the conventional case.
