Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a six-bar binding device for binding at least one pair of intersecting bars at their intersections.

(Prior Art and Problems) A wire called a dulled iron wire is widely used as a bar binding tool for binding at least one pair of bars, such as reinforcing bars, in a crossed state. The wire is
It is wound around a plurality of bars to be bound, and then both ends are twisted together to bind the bars. However, in binding work using wire, it is necessary to firmly and tightly twist both ends of the wire to bind, which requires skill on the part of the operator and requires a number of steps, making it difficult to perform the binding work efficiently. .

For example, at a construction site, to configure column reinforcements,
Four reinforcing bars (corresponding to main bars) are arranged at positions corresponding to the four corners, and other reinforcing bars (corresponding to reinforcing bars) are arranged around the main bars so as to intersect at right angles. After that, wire, which is a bar binding device, is wound around the intersection of the reinforcing bars to be bound and each main bar, and both ends of the wire are twisted to bind the reinforcing bar and the main bar. . Here, since the reinforcing bars are tied to the main reinforcing bars of the four trees, four binding operations are required for the reinforcing bars of the - wood. Since a large number of reinforcing bars are placed apart from each other in the axial direction of the main bar, there are 4 x (number of reinforcing bars) tying points even for one column bar, and - per construction work. There are a huge number of places to tie things together.

If the wire binding is not strong and tight, for example, when pouring concrete at a construction site, there is a risk that the wire may shift or come off, making it impossible to arrange the reinforcement at equal intervals and not achieving the desired strength. be.

Therefore, at construction sites, reinforcement work is carried out by a reinforcement specialist known as a reinforcement arranger, and although there are various types of reinforcement work, approximately 80% of the reinforcement work is spent on bundling. It is said to be spent on work.

Specially shaped bar ties with tubular parts and grooves for storing and supporting the bars are used in place of wire. This type of rod tying tool allows for strong and tight tying with relatively high efficiency without requiring any skill. However, because of its complicated shape, it cannot be produced at a low cost, and therefore it is difficult to use in cases where a large number of bar ties are used and are disposable, such as at construction sites.

The object of the present invention is to provide a bar binding part that can efficiently perform strong and tight binding without requiring any skill, and can be produced at low cost.

[Summary of the invention]

In order to achieve this object, according to the present invention, the bar binding tool includes a main body that stores a plurality of intersecting bars at the intersection, and this main body stores the most of the bars to be stored. The side of the outer bar is provided with a lockable notch. Furthermore, the bar binding tool includes a bolt member and a female thread member into which the bolt member is screwed, and the bolt member is attached to a side surface of the innermost bar among the bars stored in the main body. The tip is formed so that it can come into contact with. When the tip of this bolt member comes into contact with the side surface of the innermost bar, the innermost bar is pushed outward and the outermost bar is locked in the notch.

The female threaded member is, for example, comprised of a nut fixed to the main body. Then, store the intersecting bars inside the main body,
When the bolt member is screwed into the nut and moved forward, the tip of the bolt member comes into contact with the innermost bar. The innermost bar is pushed toward the outermost bar by the bolt member,
Lock the outermost bar into the notch in the main body. That is, after the intersecting bars are housed in the main body, simply by screwing the bolt member into the nut and moving it forward, a strong and tight binding can be achieved. Such binding work does not require any skill and can be performed effectively. In addition, the bar binding tool having such a structure has a simple structure, for example, by bending the plate material into a substantially U-shape, and providing side holes with one end open in each of a pair of opposing side walls. For example, the main body can be formed. Note that the side holes of the main body are communicated with the notches, respectively.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to one drawing.

As shown in FIGS. 1 and 2, a bar binding tool 10 according to the present invention can be used to connect a pair of intersecting bars, for example, reinforcing bars 1
The main body IB accommodates 2.14 at the intersection. This main body IB is provided with a notch 818 into which the side surface of the outer reinforcing bar 14 among the reinforcing bars 12.14 stored therein can be locked. In the embodiment, the notch 18 has an included angle of 90
Although the shape is a trapezoidal V-shaped groove, any shape that can lock the reinforcing bar 14 is sufficient, and is not limited to this. Shape groove, 80
The notch 18 may be formed in a V-shaped groove or the like with an included angle other than the degree.

The main body IEI is constructed by, for example, bending a plate material into a substantially U-shape. A notch 18 is formed in each of the pair of side walls 20 facing each other. In order to easily accommodate the reinforcing bars 14 in the main body 1B, side holes 22 each having a countersunk end are formed in the side wall 20, and each side hole communicates with the notch Ste. Note that if the notch 18 is formed to a size that can accommodate the reinforcing bars 14, it is not necessarily necessary to provide the side holes 22. However, if such side holes 22 are provided, the reinforcing bars 14 can be It is preferable that the plate material can be easily stored in the main body IB from any position in the longitudinal direction through the opening of the hole. In the main body 16 which is bent and has notches 18 provided in the side walls, the structure of the main body and thus the bar binding tool jO can be simplified, and the bar binding tool can be produced at low cost. The main body 1B may be formed by bending the plate material into a shape other than the substantially U-shape.

Note that the term "substantially U-shaped" includes not only the case where the side walls are parallel, but also the case where the side walls approach or move away from each other toward the end.

As can be seen from FIG. 2, a through hole 23 is bored in the central piece 21 connecting the side walls 22 of the main body, and the center of the through hole is
In order to smoothly engage the reinforcing bar 14 in the notch 18, the zero through hole 2 is located at the same level as the included angle s25 of the notch.
3, an internally threaded member, for example a nut 24, is secured to the central piece 21 by burst bonding or the like. A bolt member, for example, a hexagonal bolt 2G, is screwed into the nut 24, and the center of the bolt is located at the same level as the included angle s25 of the notch.

This bolt 2B is a reinforcing bar 12.1 stored in the main body 1B.
4, the length is such that the tip can come into contact with the side surface of the inner reinforcing bar 12.

The through hole 23 may be formed as a threaded hole, and this threaded hole may be used as a female threaded member.Also, a pair of bolts 26 may be tightened by tightening nuts with the central piece 21 of the main body in between. , it may be used as a female threaded member.

Moreover, the bolt member is not limited to a hexagonal bolt, and various other bolts with heads such as a hexagonal socket head bolt can be used. Furthermore, instead of a bolt with a head, a bolt with a through hole provided in the bolt and a rod engaged with the through hole to rotate the bolt can also be used as the bolt member.

The rod binding tool 10 having the above configuration is utilized in the following manner.

A case will be described in which column reinforcements 111 are formed at a construction site. As shown in FIG. 3, reinforcing bars 114 (corresponding to the reinforcing bars 14 in FIG. 1) bent in advance into a rectangular shape are arranged around four main bars 112 (corresponding to the reinforcing bars 12 in FIG. 1). be done. Then, the bar binding tool IO is placed with the opening between the side walls 20 of the main body facing in the direction of the arrow, and is moved in the direction of the arrow. Then, the side! ! Main reinforcement 11 through the opening between 20
2 is first stored in the main body IB. Then, the reinforcing bars 114 are aligned with the side holes 22, and the bar binding tool 10 is lowered. At this time, the reinforcing bar 114 of the bolt 2B is
It can be loosened into a retracted position through the side hole 22 of the body so as not to interfere with its storage within the body. The bolt 28 may be unscrewed from the nut 24 in advance, and the reinforcing bar 11 can be locked in the notch 18 and extended to the outside.
When the bolt 2B is moved forward after storing the reef in the main body IB, the bolt contacts the side of the main reinforcement 112 and the main reinforcement 11
2 outward, that is, in the direction of the reinforcing bar 114 (Pol)
Since the center of 2B is located at the same level as the narrow corner part 25 of the notch 825, the reinforcing bar 114 is centered on the narrow corner part 25 of the notch and moves to the notch 18 as the pole 2B moves forward. Locks smoothly. If the reinforcing bars 114 are locked in the notches 25 without play by advancing the reinforcing bars 114 sufficiently, the main bars 1
12 and 14 are completed (see Fig. 4), that is, at this point, as shown in Fig. 4, the reinforcing bars 11
4 is locked in the notch 18 and the main reinforcement 112 is pressed, so it is fixed not only in the lateral direction of the axis but also in the axial direction, and there is no room for it to separate from the bar binding device 10.On the other hand,
The main reinforcement 112 is held between the bolt 2B and the reinforcing bar 114, is blocked by the side wall of the main body, and is fixed laterally and in the axial direction.
There is absolutely no room for leaving.

As described above, according to the bar binding device 10 of the present invention, the main bar 112 and the reinforcing bar 114, which are bars, are stored in predetermined positions in the main body 16, and the bar 2B is moved forward.

Main reinforcement 112. The reinforcing bars 114 are firmly and tightly bound,
The column reinforcement 111 is easily constructed. Obviously, such tying work can be carried out efficiently without the need for skill.However, in conventional tying tools for specially shaped bars, two types are required: one for straight and one for corners. . On the other hand, the bar binding tool of the present invention, as is clear from FIG.
As is clear from the binding work in , it can also be used to bind some corners. In addition, in the configuration of the present invention, the combination of bars to be bundled is not limited to one type, that is, if a margin is provided for the distance between the side walls 20 of the main body and the distance between the notch 18 and the center piece 21, According to the forward position of the bolt member, the same bar tying tool can be applied to tying bars of various sizes, dramatically expanding the range of applications.

In addition, in the embodiment, two bars are tied together, but it is obvious that two or more bars can be tied together. In the above embodiments, the bundling of reinforcing bars as bars has been described, but it is not limited to bundling reinforcing bars, and can also be used for bundling other bars.
For example, the rod binding tool of the present invention can be used when constructing wisteria trellises and grape trellises from bamboo materials, steel materials, etc., and when constructing scaffolding from steel pipes and log materials.

(Effects of the Invention) As described above, the bar binding tool according to the present invention includes a main body that stores a plurality of intersecting bars at the intersection,
This main body is provided with a notch into which the side surface of the outermost bar among the stored bars can be locked. Furthermore, the bar binding tool includes a bolt member and a female thread member into which the bolt member is screwed, and the bolt member is one of the bars housed in the main body.

The tip is formed so that it can come into contact with the side surface of the innermost bar. When the tip of this bolt member comes into contact with the side surface of the innermost bar, the innermost bar is pushed outward and the outermost bar is locked in the notch. .

The female threaded member is, for example, comprised of a nut fixed to the main body. Then, store the intersecting bars inside the main body,
When the bolt member is screwed into the nut and moved forward, the tip of the bolt member comes into contact with the innermost bar. The innermost bar is pushed toward the outermost bar by the bolt member,
Lock the outermost bar into the notch in the main body. That is, after the intersecting bars are housed in the main body, simply by screwing the bolt member into the nut and moving it forward, a strong and tight binding can be achieved. Such binding work does not require any skill and can be performed effectively. Moreover, the bar binding tool having such a structure has a simple structure and can be produced at low cost. For example, one main body can be formed by bending a plate material into a substantially U-shape and providing side holes each having an open end in a pair of opposing side walls. Note that the side holes of the main body are communicated with the notches, respectively.

Further, the bar binding tool of the present invention can be used not only for binding straight portions but also for binding a part of a corner. Furthermore,
The combination of bars to be bound is not limited to one type or type, and the same bar binding tool can be applied to binding work of bars of various sizes. Therefore, the range of applications is dramatically expanded.

The above-mentioned embodiments are for illustrating the present invention, and are not intended to limit the present invention in any way, and any modifications, modifications, etc. made within the technical scope of the present invention are also included in the present invention. Needless to say.
