Description

[Detailed description of the device] a. “Industrial application field” The present invention is a circular steel arrangement that allows crossing a round steel bar in a vertical and horizontal crosswise at a construction site and easily staking the crossing part. It relates to a muscle fixture.

"Prior art" Conventionally, round steel was laid in a cross shape as an aggregate of columns and walls of reinforced concrete buildings, etc., and the cross part was wound with wire slightly and screwed at both ends to secure it. In this case, the round steel tends to be slanted, the wire needs to be wound several times, and the workability is poor.

In order to eliminate such defects, the inventor of the present invention first put into practice Kai-Sho 61-1.
The technology described in 92015 is proposed.

[Problems to be solved by the invention] The present invention has a simple structure of a round steel bar arrangement fixture that can easily fix the crossing part of the round steel bar and securely fix the crossing part of the reinforcing bar. Moreover, it was made with the purpose of being able to manufacture it at a lower cost than the actual Kaisho 61-19 2015 issue.

(B) "Means for solving the problem" The present invention is provided on both sides of the crossed round steel gripping circular arc 2 formed at approximately the center of one wire, in the same opening direction as the circular arc 2 and at a right angle direction. The circular steel gripping arcs 1 and 1 are formed below the crossed circular steel gripping arc 2 and at a height that does not overlap the circular arc 2, and the circular steel gripping arcs 1 and 1 cross the circular steel gripping arcs. The wire part of the space 2 is turned up and the inverted U-shaped fastening part
3,3 on the other hand, the wire at the other end of the circular steel gripping arc 1,1 is extended upward to form the end fastening parts 4,4, and the inverted U-shaped fastening part
A round steel bar arrangement fitting characterized in that it is possible to fasten 3, 3 together and end fastening portions 4, 4 respectively.

In the figure, 6 is a crossed round steel bar arrangement.

[Operation] In the present invention, first, the round steel bar arrangement 5 is gripped by the circular steel gripping arcs 1, 1, and then the crossed round steel bar arrangement 6 is placed in a direction perpendicular to the upper side of the round steel bar arrangement 5 to cross it. The circular arc of the round steel gripping arc 2 is used for gripping.

After that, the upper end and the end portion fastening portion 4 of the inverted U-shaped fastening portion 3 are twisted with a suitable tool such as pliers or by hand, and a pair of inverted U-shaped fastening portions is formed.
3, 3 and the end fastening portions 4 are fastened together, and the round steel bar arrangement 5 and the crossed round steel bar arrangement 6 are fixed.

Therefore, the round steel rebar 5 has two circular arcs for gripping the round steel 1, 1 and the round steel rebar 5 and the lower peripheral surface of the crossed round bar rebar 6 which intersects with the circular bar rebar 5.
The crossed round steel bar arrangement 6 is gripped by the crossed round steel gripping arc 2, the inverted U-shaped fastening portion 3 and the end fastening portion 4.

That is, two round steel gripping arcs 1, 1 grip the round steel bar 5 at right angles. On the other hand, the crossing round steel bar 6 is gripped at right angles to the crossing round steel gripping arc 2, the inverted U-shaped fastening portions 3, 3 and the end fastening portions 4, 4.

Therefore, since these grips act so as to be performed at right angles to the peripheral surfaces of the round steel bar arrangement 5 and the crossed round steel bar arrangements 6, the crossing portion is maintained at a right angle, unlike the case where it is provided in a space. In addition, stronger fastening is possible, and the contact force between the round steel bar arrangement 5 and the crossed round steel bar arrangement 6 is increased, so that more reliable fixing can be achieved.

"Example" Hereinafter, an example based on the drawings will be described in detail.

Made of appropriate materials such as iron, aluminum, copper,
An arc 2 for gripping a crossed round steel is formed substantially at the center of a wire having an appropriate thickness. It is desirable that the length of the crossed round steel gripping arc 2 should grip half or more of the crossed round steel bar arrangement 6 in consideration of workability of fastening work.

Next, on both sides of the gripping arc 2, wires in the same direction and at a right angle to the crossed round steel gripping arc 2 are folded back to form a pair of inverted U-shaped fastening portions 3, 3.

The length of the inverted U-shaped fastening portions 3,3 is such that the inverted U-shaped fastening portions 3,3 are bent along the circumferential surface of the crossed round steel bar arrangement 6 and the pair of inverted U-shaped fastening portions 3,3 are connected to each other. The length that can be fastened is required. However, when using the fastening member 7 having an appropriate structure such as connecting with a wire or the like as shown in FIG. 6, it is sufficient that the fastening member 7 has a length that enables fastening.

Also, the inverted U-shaped fastening part 3 on the opposite side of the crossed round steel gripping arc 2,
Round steel gripping arcs 1, 1 are provided at the respective end portions of 3 in the same opening direction as the arc 2 and in the right angle direction (the same direction as the inverted U-shaped fastening portion 3).

The positions where the round steel gripping arcs 1 and 1 are provided are the intersections of the round steel gripping arcs 1 and 1 and the upper circumferential surface of the round steel bar arrangement 5 which is gripped by the round steel gripping arcs 1 and 2. The position is such that it contacts the lower peripheral surface of the round steel bar arrangement 6.

In addition, the reverse U of the circular steel gripping arcs 1 and 1 that grip the round steel bar arrangement 5
The tip end portion on the side opposite to the character-shaped fastening portion 3 is formed with end fastening portions 4 and 4 having such a length as to be located above the crossed round steel bar arrangement 6 when the crossed round steel bar arrangement 6 is attached to this article. Has been done.

In this embodiment, the inverted U-shaped fastening portions 3 and 3 and the end fastening portions 4 and 4 are
In order to facilitate the fastening to the crossed round steel bar 6, respectively, the crossed round steel holding curved portion 8 is formed to favorably support the rounded steel bar 5 and the crossed round steel bar 6. However, the curved portion 8 may not be formed.

This embodiment is configured as described above, and after the round steel bar arrangement 5 is inserted into the round steel gripping arc 1, the crossed round steel bar arrangement 6 is inserted into the crossed round steel gripping arc 2.

Next, the pair of inverted U-shaped fastening portions 3 and the end fastening portions 4 are twisted and fastened with pliers or the like.

When fastening the inverted U-shaped fastening portions 3 to each other, a rod-shaped tool may be inserted into the pair of inverted U-shaped fastening portions 3 and twisted.

C. "Effect of the device" The present invention has a plurality of fixing points for the round steel bar and the crossed round bar bar, even though the wire is formed by one wire as described above, and the wire is gripped by the wire. Since the part always acts at right angles to the round bar reinforcement and the crossed round bar reinforcement, the cross part where the round bar reinforcement and the crossed round steel reinforcement intersect can be fixed accurately and reliably. .

In addition, since the fastening parts are also arranged close to each other in one direction, workability is good, and since it is formed with a predetermined length from the beginning,
It is possible to eliminate the waste of excessively winding the wire as in the conventional case.

Further, the wire can be manufactured only by bending and bending the wire, and there is no need for processing by other means such as welding, and it has an excellent effect that it can be mass-produced at low cost.
