Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for binding rebars together. 2. Description of the Related Art In a steel bar assembling work performed in a concrete factory or a construction site, a steel wire having no spring property is generally converted into a U-shape having a length that is easily entangled with a joint of reinforcing bars. Bent binding wire (so-called number line)
You are using [0003] While the rebar assembler bundles the binding wires and holds it in one hand, the other hand holds a binding work tool called a hacker, pulls out the binding wires one by one, and reinforces the reinforcing bars. It is a common practice to entangle the part and twist it up by twisting the work tool. [0004] However, in this case, the rebar assembling worker wears gloves, and the rebar assembling is performed one by one from the bundle of binding wires held in one hand. -It is very troublesome and difficult to smoothly extract the wire, and at that time, an excessive binding wire tends to be dropped or scattered. [0005] In addition, a rebar assembler cannot use one hand to hold and hold the binding wire and is free to use it.
Entanglement of the binding wire to the joint of the reinforcing bars,
Since it must be tied up by the swinging operation of the above-mentioned work tool, it is extremely inconvenient and heavy labor, and it is not possible to efficiently perform the rebar assembling work with the binding wires, and the binding condition varies. Easily and inferior in its binding strength and stability. SUMMARY OF THE INVENTION [0006] The present invention is intended to solve such a problem, and as a tool for joining together reinforcing bars of reinforcing bars, a piano wire or other spring is useful. A single piano wire or another metal wire exhibiting a spring property, and a base end portion of the metal wire cut off is bent as a first hook hooking to the first reinforcing bar, And continuously extending the back regulating bar from the bent base of the first winding hook in a direction obliquely crossing the back surfaces of the first and second reinforcing bars by a predetermined working length, [0008] The hook bar for the second reinforcing bar is continuously bent from the front end portion of the back regulating bar to the second reinforcing bar by about 90 degrees in the same front direction as the first hooking hook. And rear regulation And the hooking bar is positioned on the same first holding plane that intersects at right angles to the longitudinal center lines of the first and second reinforcing bars as a whole. Further, the front regulation bar is continuously bent in a direction crossing the rear regulation bar by about 90 degrees, and the front of the first and second reinforcing bars is inclined.
And extends linearly by a certain operating length longer than the back regulating bar , and is located at the cutting end of the metal wire rod from the extending end of the front regulating bar. A second winding hook on the first reinforcing bar is bent by about 90 degrees in a direction opposite to the first winding hook, and the second winding hook, the front regulating bar, and the hanging bar are provided. By being located on the same second holding plane which is substantially orthogonal to the first holding plane as a whole and intersects at right angles to the longitudinal center lines of the first and second reinforcing bars, In the temporary hooking state in which the first winding hook, the back regulation bar, and the hook bar on the first holding plane are held by the first and second reinforcing bars from the back, the first hook is still in a free state . front regulation server on a two-embracing plane The,
The second bar hook is formed by forcibly pushing down the first and second rebars obliquely in the transverse direction using the hooking position of the hook bar with respect to the second rebar as a fulcrum, and releasing the operating hand. Is defined so as to be able to be hooked on the back surface of the first reinforcing bar. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the specific structure of the present invention will be described in detail with reference to the drawings. A binding tool according to the present invention is used for binding substantially parallel reinforcing portions of adjacent reinforcing bars. It is bent from a single piano wire or other metal wire material exhibiting spring properties into an overall shape as shown in FIGS. That is, in FIGS. 1 to 7 showing the binding tool and its use, (11) is a first hook hooked to a first reinforcing bar (Y) serving as a separation base end of a spring metal wire.

Are to some extent longer dimensioned than the working length of 2) (L2)
ing. (15) The direction from the front end of the front regulation bar (14) to the direction opposite to the first hooking hook (11) is about 90 degrees (δ) toward the back of the first reinforcing bar (Y). It is a second winding hook that is continuously bent, and is bent into an arch shape or a V-shape that can fit on the outer peripheral surface of the arc of the first reinforcing bar (Y). That is, the second winding hook (15)
And the front regulating bar (14) and the latching bar (13) as a whole are on the same second holding plane indicated by another reference numeral (B) in FIG. ) Is substantially perpendicular to the first holding plane (A) as viewed from the front, as is apparent from the intersection of about 90 degrees (γ) between the back regulation bar (12) and the front regulation bar (14). I have. Therefore, the second holding plane (B) is also clear from FIG.

4) is kept in a holding state. Needless to say, the second hook (15) for hooking the first reinforcing bar (Y) forms a cutting end of the spring metal wire. (W) is a joint between the first and second reinforcing bars (Y) and (Z).
The width of the overlapped portion is shown. When using such a tying tool to tie the substantially parallel joint portions of the first and second reinforcing bars (Y) and (Z) adjacent to each other, first , solid lines shown in FIGS. Like
A first hook (11) serving as a base for separating the spring-like metal wire is temporarily hooked to the first reinforcing bar (Y), and a hook bar (13) and a back regulating bar are provided. (12), the first and second rebars (Y)
(Z) is held from the back. In such a state that the hook is temporarily locked ,
When viewed from the front as in FIGS. 8 and 9, the front regulating bar (14) intersects the rear regulating bar (12) by about 90 degrees (γ) , and the second hooking hook ( 15) is still in a free state. Then, next , the front regulation bar (14) on the second holding plane (B) is changed from the chain line in FIGS.
, This is the front of entirely forcibly pushing notwithstanding et obliquely laterally restraining the first and second reinforcing bar (Y) (Z), second Maki hook (15) Figure 8 positioned at its extended tip portion, 9 of
As shown in FIG. 4 and FIG. 5 from the chain line, the first rebar (Y) is hooked on the back surface, and then the operating hand is released. Then, as shown in FIGS. 4 and 5, the first winding hook (11), the back regulating bar (12) and the hanging bar (13) on the first holding plane (A) are placed on the back. The second hooking hook (15), the front regulating bar (14) and the hooking bar (13) on the second holding plane (B), which intersect with this by about 90 degrees (γ), head on,
In both cases, the first and second rebars (Y) and (Z) are held so as to be sandwiched therebetween, and the extension portion is locked in a firmly tied state, and the first bending portion is bent at the root of the back regulation bar (12).
The winding hook (11) is the outer peripheral surface of the arc of the first reinforcing bar (Y).
While the second hook (15) located at the extension end of the front regulation bar (14)
Eating the repressive retaining state to the arc outer peripheral surface of the first reinforcing bar (Y)
Results stick. From the chain line in FIGS. 8 and 9 to the state in FIGS.
In the binding operation process, the front regulating bar (14) performs a pivoting motion with the engaging position of the engaging bar (13) with respect to the arc outer peripheral surface of the second reinforcing bar (Z) as a fulcrum (P), and the extension tip of the extension tip thereof. The two winding hooks (15) are opposed to the spring force of the metal wire, and the arrow (F2) in FIG.
It will bite resiliently from the direction
The winding hook (11) also resists the spring force of the metal wire
Then, the arrow (F) of FIG.
1) Since it resiliently bites from the direction, it is possible to bind the reinforced portions of the first and second rebars (Y) and (Z) in a stable and strong binding state, and to reduce external force such as vibration and impact. However, there is no danger that the binding tool will fall off, of course, and that both rebars (Y) and (Z) may move relatively in the forward and backward directions, and may also move relatively along the longitudinal center line. Move to
Side-by-side, especially in vertical
When applied to the reinforcement of comrades (Y) and (Z),
It is extremely effective. In this case, the fixing strength of the replenishment portion is as follows:
Working length (L1) of the front regulation bar (14) that performs the roller movement
And the thickness of the metal wire can be appropriately adjusted in consideration of the relationship. However, it is preferable that the thickness of the metal wire is set to be smaller than the adjacent gaps of the horizontal bars (a) in the reinforcing bars (Y) and (Z). This is because the horizontal section (a) can obtain the anti-slip effect of the binding tool. (B) similarly shows the vertical bar of the reinforcing bar (Y) (Z). Although the binding tool applied to the joint of the reinforcing bars (Y) and (Z) adjacent to each other in the vertical state as the frame of the concrete wall slab has been described above, it is horizontally aligned as the frame of the concrete floor slab. Needless to say, the binding tool can also be used without any trouble in the same reinforcing sequence of the reinforcing bars (Y) and (Z) that fit together. As described above, the present invention comprises a single piano wire or another metal wire exhibiting spring properties as a tool for binding the reinforcing bars of adjacent reinforcing bars (Y) and (Z). The bent base end of the metal wire is bent as a first hook (11) for the first reinforcing bar (Y), and the back regulation is continued from the bent base of the first hook (11). The bar (12) is linearly extended by a certain working length (L2) in a direction obliquely crossing the back surfaces of the first and second reinforcing bars (Y) and (Z). Next, the hook bar (13) from the extension end portion of the first reinforcing hook (11) to the second reinforcing bar (Z) is temporarily moved by about 9 in the same front direction as the first hooking hook (11).
The first winding hook (11), the back regulating bar (12) and the hanging bar (13) are entirely folded with the first and second reinforcing bars (Y) (Z). ) Non-perpendicular to longitudinal centerline
While being located on the same first holding plane (A) intersecting with (β) , the front regulating bar (14) is further moved from the bent end of the latch bar (13) to the rear regulating bar. It is bent in a direction crossing the bar (12) by about 90 degrees (γ) so as to obliquely cross the front surfaces of the first and second reinforcing bars (Y) and (Z) and is longer than the back regulating bar (12). It is linearly extended by a fixed working length (L1). From the front end of the front regulating bar (14) to the first reinforcing bar (Y) which is located at the cutting front end of the metal wire rod. Of the second winding hook (15)
Approximately 90 degrees in the opposite direction to the first winding hook (11)
(Δ), and the second winding hook (15), the front regulating bar (14), and the retaining bar (13) as a whole are substantially orthogonal to the first holding plane (A). And the first and second
By being located on the same second holding plane (B) which intersects at right angles (ε) with the longitudinal center lines of the reinforcing bars (Y) and (Z), the first holding The first hook (11), the back regulation bar (12) and the hook bar (13) on the plane (A) are held by the first and second rebars (Y) and (Z) from the back. In the hooked state, the front regulation bar (1 ) on the second holding plane (B), which is still in a free state,
4) the hook bar (13) for the second reinforcing bar (Z).
The forcible position is set as the fulcrum of pivoting motion (P), and the first and second rebars (Y) and (Z) are forcibly pushed down in the diagonal transverse direction, and the operating hand is released, whereby the second winding is performed. Since the hook (15) is configured to be hooked to the back surface of the first reinforcing bar (Y), anyone can easily add the adjacent first and second reinforcing bars (Y) and (Z) to the one-touch type. The binding work can be performed well, and in spite of this, a stable and strong binding state can always be obtained, and the problems of the prior art described at the beginning can be surely improved.
