DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod-like support for fixing rod-like bodies such as rebars, iron pipes, etc. in a cross shape.

[0002]

2. Description of the Related Art Heretofore, in order to assemble and fix a rod-shaped body such as a reinforcing bar in a cross shape, a tying tool such as a hacker has been used to bind a crossing point with a binding wire. Further, at the time of transportation, the individual rods are transported as a bundle, but at the construction site, the rods are once broken down one by one and then assembled. Further, the formwork is arranged at a fixed distance from the reinforcing bar, and is fixed using bolts and nuts.

[0003]

However, in order to assemble the rods one by one at the construction site, it is necessary to first position the cross-shaped intersections and securely bind them at that position. It took a lot of skill and time to securely bind all the crossover points by hand. Therefore,
It was conceived that the crossed rods were connected and transported by means of welding or the like before the construction, but there was a problem that the crossed rods were bulky and difficult to transport to the construction location. In addition, since the reinforcing bar and the formwork are not fastened, it is difficult to set the cover thickness of the concrete to the reinforcing bar constant, and the reinforcing bar is easily rusted. The present invention has been made in view of the above circumstances, and provides a rod-shaped body support that can be connected in advance and transported in a state of being folded in parallel while being crossed, and that can be deployed in a cross shape at an installation location. The purpose is to: It is another object of the present invention to provide a rod-shaped support which makes the cover thickness of concrete constant.

[0004]

In order to solve the above-mentioned problems, the present invention forms a bar-shaped body by bending the front end and forms a cut in the rear end in the longitudinal direction. Bend the tip of the cut into an arc shape to fix the other rod-shaped body,
A fixed portion having a guide portion at the tip is formed, and two supports are formed so that a leg portion having a stopper and a slip stopper can be bent freely, and the rear portions of the support are connected to each other by a connecting body. And

[0005]

The two rods are stacked one on top of the other, the upper part of one rod is supported by the connecting part of the rod support, and the lower part of the lower rod is supported by two grips at the tip of the support. I do. Carrying is performed in this state. When assembling, the upper rod is rotated with the connecting portion as a fulcrum, is perpendicular to the lower rod, and the upper rod is fixed by a fixing portion formed at the rear end.
When fixing the third rod-shaped body, the third rod-shaped body is fixed orthogonally to the two rod-shaped bodies on a fixing part extending to the side of one of the supports. Since a pair of legs is provided on the side of each support, when the legs are inserted into the temporary frame plate, the distance between the rod-shaped body crossing in a cross shape and the temporary frame plate can be adjusted accurately, and concrete The fog can be kept constant.

[0006]

1 is a plan view of an embodiment of the present invention, FIG. 2 is a side view of the same, and FIGS. 3 and 4 are perspective views of a rod-like body in a supported state. The rod-shaped body support 1 is formed by connecting one end of a support 2 having a gripping portion 3 of a reinforcing bar 30 at a tip thereof in a symmetrical shape by a connecting portion 7, and has a substantially S-shaped back surface as a whole. . Gripping portion 3 formed by narrowing the tip of support 2
Is curved in a semicircular shape so as to hold the lower outer periphery of the reinforcing bar 30, and reliably supports the lower reinforcing bar 30. A notch 4 is formed in the rear part of the support 2 along the longitudinal direction, and the upper reinforcing bar 2 is formed.
The fixed part 5 and the fixed part 6 are formed. This fixing part 5,
Numeral 6 is formed by bending the ends of the support 2 divided into two by the cuts 4 outwardly in an arc shape. Further, guide ends 5a and 6a are provided by further folding the tip outward. Since the fixing portions 5 and 6 have the above configuration,
The upper rebar 20 intersecting with the rebar 30 is guided by the guide pieces 5a and 6a.
And can be reliably supported by the arc-shaped fixing portions 5 and 6. The connecting part 7 connects the supports 2 and 2 in parallel. At this time, the connecting portion 7 is connected to the fixing portions 5 and 5 in an oblique direction, and the center is curved upward to form an arc-shaped portion. Also,
Since the rod-like body support 1 is formed by integrally forming processed spring steel, the rod-like body support 1 is rich in elastic force, and has a grip portion 3 or fixing portions 5 and 6.
Can reliably support the rebars 20 and 30.

Next, the operation of this embodiment will be described. As shown in FIG. 3, the reinforcing bars 20 and the reinforcing bars 30 are stacked in parallel, and the connecting portions 7 support the reinforcing bars 20 from above. At the same time, two lower peripheral surfaces of the rebar 30 are grasped by the grasping portions 3 and 3 at the tip, and the two rebars 2 are
0 and 30 are simultaneously supported by being tightened from above and below. In this case, since the bushes 21 and 31 are formed on the peripheral surfaces of the rebars 20 and 30, the grip portion 3 engages with the bushes, and
The engagement of the bushing 21 and the bushing 31 prevents displacement of the reinforcing bar. The rebar is transported in a state where the rebar 20 and the rebar 30 are stacked in parallel as described above, and the upper rebar 20 is rotated in the horizontal direction with the connecting portion 7 as a fulcrum during construction. When the reinforcing bar 20 comes to a position orthogonal to the reinforcing bar 30, the reinforcing bar 20 is fitted into the fixing portions 5 and 6 of the supports 2 and 2 and fixed. Since the fixing portions 5 and 6 are provided with the guide portions 5a and 6a at the tips, the reinforcing bar 20 can be easily fitted. In addition, since the fixing portions 5 and 6 are formed in an arc shape, the reinforcing bar is hardly removed, and the fixing can be surely performed by the elastic force. Even if the rebar 20 is rotated in the horizontal direction and stopped at a position other than a right angle, the upper rebar 20 is fastened to the lower rebar 30 by the connecting portion 7. Instead of being orthogonal, it can be fixed at any angle.

As described above, according to the present embodiment, the rebars 20 and 30 to be fixed in a cross shape can be stored and transported in a factory in a combined and folded state in advance. Further, since the reinforcing bar 20 can be securely fixed only by being fitted to the fixing portions 5 and 6 perpendicularly to the reinforcing bar 30 with the connecting portion 7 as a center, the labor of binding at the construction site can be greatly reduced.
It is particularly useful when working in bad weather or by unskilled workers. In this embodiment, the deformed bar (SD) is used, but the present invention can be applied to a round bar (SR) and an iron pipe.
