Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rod-shaped support for fixing rod-shaped members such as reinforcing bars and iron pipes in a cross shape in a cross shape.

(Prior Art) Conventionally, in order to assemble and fix a rod-shaped body such as a reinforcing bar in a cross shape, a binding tool such as a mint has been used to bind the crossing points with a binding line. In addition, the individual rod-shaped bodies are transported as a bundle during transportation, but at the construction site, they are temporarily separated into individual pieces and then assembled.

Furthermore, the formwork is arranged at a constant distance from the reinforcing bar and is fixed using bolts and nuts.

(Problems to be solved by the invention) However, in order to assemble the rod-shaped bodies one by one at the construction site, it is necessary to first position the cross-shaped sites and securely bind them at that position. And it took skill and time to securely tie all the crossing points by hand.

Therefore, it has been considered that the rod-shaped bodies that intersect with each other in advance are connected by means such as welding before carrying out the work, but the cross-shaped work is bulky and therefore difficult to carry to the work site.

Further, since the reinforcing bar and the formwork are not fastened, it is difficult to set the cover thickness of the concrete to the constant reinforcing bar, and the reinforcing bar is likely to be rusted.

The present invention has been made in view of the above circumstances, and provides a rod-shaped body support that can be transported in a state in which rod-shaped bodies that intersect with each other are connected in advance and folded in parallel and can be expanded in a cross shape at an installation location. The purpose is to Moreover, it aims at providing the rod-shaped body support tool which makes the cover thickness of concrete constant.

(Means for Solving the Problems) In order to solve the above problems, the present invention bends the tip inward in a semi-circular shape to form a grip portion of one rod-like body, and cuts the rear end in the longitudinal direction. And forming a fixing portion for fixing another rod-shaped body by bending the tip end of this notch into an arc shape, and connecting the rear portions of the supporting body to each other with a coupling portion. Is characterized by. Further, the inside of the fixed portion of the one support is bent at a right angle to form a bent portion, and a rod-shaped fixed portion is formed at an end of the bent portion.

Further, the present invention is characterized in that a pair of legs is provided on the side of the support, and the legs are bent in the vertical direction with respect to the support.

(Function) Two rod-shaped bodies are vertically stacked, one rod-shaped body is supported by the connecting portion of the rod-shaped body support, and the lower portion of the rod-shaped body is supported by the two gripping portions at the tip of the support body. To do. Transport in this state.

When assembling, the upper rod-shaped body is rotated about the connecting portion as a fulcrum so as to be orthogonal to the lower rod-shaped body, and the upper rod-shaped body is fixed by the fixing portion formed at the rear end. Further, when the third rod-shaped body is fixed, it is fixed to the fixing portion extending to the side portion of the one support body so as to be orthogonal to the two rod-shaped bodies.

If you have integrated legs on the side of each support,
Insert the legs into the temporary frame plate. This makes it possible to accurately adjust the distance between the rod-shaped body crossed in a cross shape and the temporary frame plate, and to keep the concrete covering constant.

(Embodiment) FIG. 1 is a plan view of an embodiment of the present invention, FIG. 2 is a side view thereof, and FIGS. 3 and 4 are perspective views of a rod-shaped body in a supported state.

The rod-shaped body support tool 1 is formed by connecting one end of a support body 2 having a grip portion 3 of a reinforcing bar 30 formed at its tip end with a connecting portion 7 in a symmetrical shape, and has a substantially S-shaped back surface as a whole. .

The grip 3 formed by thinning the tip of the support 2 is used for the reinforcing bar 30.
It is curved in a semi-circular shape so as to hold the outer periphery of the lower part of the above, and reliably supports the lower reinforcing bar 30.

A notch 4 is formed in the rear portion of the support body 2 along the longitudinal direction, and a fixing portion 5 and a fixing portion 6 of the upper reinforcing bar 20 are formed. The fixing portions 5 and 6 are formed by bending the ends of the support body 2 divided into two by the notch 4 in an arc shape toward the outside. And
Further, the tip ends are folded back to provide guide pieces 5a and 6a. Since the fixing portions 5 and 6 are configured as described above, the upper reinforcing bar 20 intersecting with the reinforcing bar 30 can be guided by the guide pieces 5a and 6a and reliably supported by the arc-shaped fixing portions 5 and 6.

The connecting portion 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.

Further, since the rod-shaped body supporting tool 1 is formed by integrally forming machined spring steel, it has a high elastic force, and the grip portions 3 or the fixing portions 5 and 6 can reliably support the reinforcing bars 20 and 30.

Next, the operation of this embodiment will be described. As shown in FIG.
The reinforcing bar 20 and the reinforcing bar 30 are stacked in parallel, and the connecting part 7 supports the reinforcing bar 20 from above.

By the elastic force of, the two reinforcing bars 20 and 30 are tightened vertically and supported simultaneously.

In this case, since the reinforcements 21 and 31 are formed on the peripheral surfaces of the reinforcing bars 20 and 30, the grip portion 3 engages with the reinforcement 21, and
The engagement between 21 and the bush 31 prevents the reinforcing bars from being displaced.

The rebar is carried in the state where the rebar 20 and the rebar 30 are stacked in parallel as described above, and the upper rebar 20 is horizontally rotated with the connecting portion 7 as a fulcrum at the time of construction. When the reinforcing bar 20 comes to a position orthogonal to the reinforcing bar 30, the fixing portions 5 and 6 of the two supports 2 and 2 are
Reinforcing bar 20 is inserted into and fixed. Since the fixed portions 5 and 6 are provided with the guide portions 5a and 6a at their tips, the reinforcing bars 20 can be easily fitted therein. Further, since the fixed parts 5 and 6 are formed in an arc shape,
Reinforcement is hard to come off, and its elastic force allows it to be securely fixed.

Even if the reinforcing bar 20 is rotated horizontally and stopped at a position other than a right angle, the upper reinforcing bar 20 is fastened to the lower reinforcing bar 30 by the connecting portion 7.
Can be fixed at any angle instead of in the orthogonal state.

As described above, according to the present embodiment, the reinforcing bars 20 and 30 that are crossed and fixed in a cross shape can be stored and transported in advance in a state of being combined and folded in a factory. Further, since the reinforcing bar 20 can be securely fixed only by fitting it to the fixing sections 5 and 6 so that the reinforcing bar 20 is orthogonal to the reinforcing bar 30 with the connecting section 7 as the center, the labor of binding at the construction site can be greatly reduced.
