Abstract

PROBLEM TO BE SOLVED: To provide a reinforcing bar holder capable of reducing the labor of arrangement. SOLUTION: A reinforcing bar holder 1 has a contact portion 2 that comes into contact with a mold and a flat surface portion 5 in which a plurality of pair of reinforcing bar holding portions 3 that sandwich and hold the reinforcing bar at a position separated from the mold are arranged in a linear direction. The base 6 is provided. Then, a fitting groove 8 into which a reinforcing bar extending in a direction orthogonal to a straight line direction is formed is formed in the flat surface portion 5. As a result, the reinforcing bar holder 1 can hold two intersecting reinforcing bars, so that the number of the reinforcing bar holders 1 to be arranged can be reduced. Further, since the two reinforcing bars to be held are substantially orthogonal to each other, the reinforcing bar holder 1 does not easily shift in position. Therefore, the labor for arranging the reinforcing bar holder 1 can be significantly reduced. [Selection diagram] Fig. 1

Description

The present invention relates to a reinforcing bar holder, particularly a reinforcing bar holder arranged in a reinforced concrete structure in order to maintain a separation distance between the reinforcing bar and the mold.

In the molding of a reinforced concrete structure, first, the reinforcing bars are assembled and arranged in a predetermined shape, then the mold is arranged around the mold, and then the reinforcing bar holder is attached to the reinforcing bar group closest to the inner surface of the mold and the inner surface of the mold to form the inner surface of the mold. A construction method that secures an appropriate distance from the reinforcing bar group is common. As a result, the distance between the surface of the reinforced concrete structure and the reinforcing bar group can be maintained at a predetermined specified value.
Therefore, conventionally, a reinforcing bar having a base having a contact portion that abuts on the mold and a flat surface portion in which a plurality of pair of reinforcing bar holding portions that sandwich and hold the reinforcing bar at a position separated from the mold are arranged in a straight line direction. Holders are known (see, for example, Patent Document 1).

However, since the reinforcing bar holder of Patent Document 1 can hold only one reinforcing bar, a large number of reinforcing bar holders are required to hold a plurality of reinforcing bars.
In addition, the rebar holder may be displaced by rotating itself around the rebar held as a rotation axis.

For this reason, it becomes necessary to correct the position of the reinforcing bar holder each time, and there is a problem that the time and effort for arranging the reinforcing bar holder increases.
Further, since the reinforcing bar holder can be a foreign substance in the reinforced concrete structure, if the number increases and the volume occupancy in the reinforced concrete structure becomes large, there is a possibility that it may cause a problem related to the strength of the reinforced concrete structure.

Utility Model Registration No. 3163336

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a reinforcing bar holder capable of reducing the labor of arrangement.

According to the present invention, the reinforcing bar holder has a contact portion that abuts on the mold and a flat surface portion in which a plurality of pair of reinforcing bar holding portions that sandwich and hold the reinforcing bar at a position separated from the mold are arranged in a straight line direction. It has a base to have.
Then, a fitting groove into which a reinforcing bar extending in a direction orthogonal to a straight line direction is formed is formed in the flat surface portion.

As a result, the reinforcing bar holder can hold two intersecting reinforcing bars, so that the number of reinforcing bar holders to be arranged can be reduced. Further, since the two reinforcing bars to be held are substantially orthogonal to each other, the reinforcing bar holder does not easily shift in position.
Therefore, the labor of arranging the reinforcing bar holder can be significantly reduced.
Furthermore, since the number of reinforcing bar holders can be reduced, the volume occupancy rate of foreign matter in the reinforced concrete structure can be reduced.

It is a perspective view of the reinforcing bar holder (second embodiment). It is a correlation diagram of a reinforcing bar holder and a reinforcing bar (second embodiment). It is a perspective view of a reinforcing bar holder (a modified example).

Hereinafter, embodiments for carrying out the device will be described based on examples.

[First Example]
The reinforcing bar holder 1 according to the first embodiment of the present invention is shown in FIGS. 1 and 2.
It should be noted that the following examples disclose a specific example, and it goes without saying that the present invention is not limited to the following examples.

The reinforcing bar holder 1 has a base portion having a contact portion 2 that abuts on the mold and a flat surface portion 5 in which a plurality of pair of reinforcing bar holding portions 3 that sandwich and hold the reinforcing bars at positions separated from the mold are arranged in a straight line direction. 6 is provided.
Since the base 6 is made of mortar or concrete, it has a high affinity with ready-mixed concrete introduced into the mold.

The reinforcing bar holder 1 is formed with a fitting groove 8 in which a reinforcing bar extending in a direction orthogonal to a straight line direction is fitted in the flat surface portion 5.
Further, the reinforcing bar holder 1 has a shape that tapers as the base 6 approaches the formwork.
Further, in the reinforcing bar holder 1, the reinforcing bar holding portion 3 is formed in a hook shape.

[Effect of the first embodiment]
The reinforcing bar holder 1 is formed with a fitting groove 8 in which a reinforcing bar extending in a direction orthogonal to a straight line direction is fitted in the flat surface portion 5.
As a result, the reinforcing bar holder 1 can hold two intersecting reinforcing bars, so that the number of the reinforcing bar holders 1 to be arranged can be reduced. Further, since the two reinforcing bars to be held are substantially orthogonal to each other, the reinforcing bar holder 1 does not easily shift in position.
Therefore, the labor for arranging the reinforcing bar holder 1 can be significantly reduced.

Since the volume occupancy of the reinforcing bar holder 1 that can be a foreign substance in the reinforced concrete structure can be reduced, it is possible to suppress the occurrence of problems related to strength reduction due to the presence of foreign substances in the reinforced concrete structure.

Further, the reinforcing bar holder 1 has a shape that tapers as the base 6 approaches the mold.
Therefore, the area of the reinforcing bar holder 1 exposed on the surface of the reinforced concrete structure can be reduced.
Further, in the reinforcing bar holder 1, the reinforcing bar holding portion 3 is formed in a hook shape. Therefore, the tip of the reinforcing bar holding portion 3 covers the reinforcing bar, and the reinforcing bar does not easily come off from the reinforcing bar holding portion 3.

[Second Example]
The reinforcing bar holder 1 according to the second embodiment of the present invention is shown in FIGS. 3 and 4.
In the second embodiment, the parts different from those in the first embodiment will be mainly described.
In the figure, the same functional objects as those of the first embodiment are designated by the same reference numerals.

The reinforcing bar holder 1 has a base 6 having a square pyramid shape with a flat surface portion 5 as a wide bottom surface, and a contact portion 2 is provided vertically at four corners of a narrow bottom surface 10 facing the wide bottom surface. Has been done.
Further, a side groove 11 for connecting the fitting groove 8 and the narrow bottom surface 10 is formed in the base portion 6.

[Effect of the second embodiment]
In the reinforcing bar holder 1, the contact portion 2 is projected at the four corners of the narrow bottom surface 10 facing the wide bottom surface perpendicularly to the narrow bottom surface 10.
As a result, the plurality of contact portions 2 come into contact with the mold, so that the contact with the mold becomes more stable.
Further, a side groove 11 for connecting the fitting groove 8 and the narrow bottom surface 10 is formed in the base portion 6.
As a result, the ready-mixed concrete introduced into the mold via the side groove 11 can be smoothly guided to the narrow bottom surface 10.

[Modification example]
The present invention can consider various modified examples without departing from the gist of the present invention.
In the embodiment, the reinforcing bar holder 1 is provided with four pairs of reinforcing bar holding portions 3, but the number is not particularly limited.

Further, in the embodiment, the reinforcing bar holding portion 3 is formed in a hook shape, but the reinforcing bar holding portion 3 may be a plate-shaped body having a width in a straight line direction as shown in FIG.
As a result, the holding force of the reinforcing bar can be easily adjusted by changing the width, thickness, and the like of the plate-shaped body.
When the reinforcing bar holding portion 3 is formed into a plate-like body, the area embedded in the base portion 6 increases, so that the connection strength between the base portion 6 and the reinforcing bar holding portion 3 becomes high.
