DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint clip attaching device for attaching a joint clip for fixing a vertical bar and a horizontal bar to one reinforcing bar.

[0002]

2. Description of the Related Art In a reinforcing bar arranging operation when constructing a reinforced concrete frame, for example, in the case of a wall reinforcing bar, first, a plurality of vertical bars 1 are arranged at predetermined intervals, and then a standard vertical bar is used. 1 are marked at predetermined intervals, and then the horizontal stripes 2 are arranged and bound one by one at the marked portions to form a lattice shape. Finally, as shown in FIG. A method of bundling the intersection 3 with 2 is adopted.

On the other hand, in large-scale construction, U bolts (not shown) are welded at predetermined intervals to a vertical bar 1 serving as a reference, and horizontal bars 2 are dropped into grooves of the U bolt based on this. Attempts have been made to improve work efficiency.

[0004] Incidentally, in the former construction method of the above-mentioned rebar arrangement work, there is a problem that improvement of the work efficiency cannot be expected because all the arrangement work of the rebar depends on humans. In addition, in the latter method, it takes time and effort to weld the U-bolt, and the U-bolt is used as a temporary member only since the material of the rebar is likely to deteriorate due to heat generated by welding. Since it is necessary to arrange a permanent contact member,
There is a problem that the cost increases.

Therefore, the vertical streak 1 and the horizontal streak 2 are replaced with U bolts.
A method of fixing each intersection 3 with a connection fitting serving as a joint clip is being studied. As shown in FIG. 6, the joint clip 3 has a substantially U-shaped vertical streak gripping portion 4 that arranges and holds the vertical streak 1 inside thereof, and Horizontal line 2 arranged in a crossed state
And a substantially U-shaped horizontal streak gripping portion 5 which grips the inside of the bar. If this joint clip 3 is used, not only the work of binding the reinforcing bars is omitted, but also the material is not deteriorated because no heat is applied to the reinforcing bars, and the joint clip 3 can be used as a permanent member. Cost can be reduced.

[0006]

However, when attaching the joint clips to the horizontal streaks, the following problems occur because the worker manually attaches the clips one by one using tools such as pliers. . Since they are manually attached one by one, productivity is not improved, labor costs are increased, and costs are increased. Since it cannot be mounted at an appropriate position (the mounting accuracy is low), it is often necessary to correct the mounting position at the stage of mounting on the vertical streak. The physical load on workers is large.

The present invention has been made in view of the above circumstances, and has as its object to simplify the work of attaching a joint clip, improve productivity, and reduce the cost required for the work.

[0008]

As means for solving the above-mentioned problems, a joint clip attaching device for attaching a joint clip to a horizontal streak is employed. The joint clip mounting device is provided with a base provided with a plurality of projections which are inserted through and hold the vertical streak gripping portions of the joint clip, and are movably supported so as to approach and separate from the base. A pressing member is provided which comes into contact with a horizontal line arranged on the horizontal line grip portion of each joint clip by approaching to the platform side and presses the horizontal line inside the horizontal line grip portion.

In this joint clip mounting device, the lateral streaks are pushed into the lateral streak gripping portions of the plurality of joint clips arranged on the base at a time by the pressing member, so that the plurality of joint clips are once inserted into one transverse streak. Can be mounted on the device, and work efficiency can be improved.

In addition, if a link mechanism is employed as a means for moving the pressing member, the operation of pushing the horizontal streaks into the horizontal streak gripper can be performed with a small force. Further, if the driving cylinder such as an air cylinder or a hydraulic cylinder is combined with the means for moving the pressing member, the apparatus can be automated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a joint clip attaching device according to the present invention will be described with reference to FIGS. The joint clip attaching device shown in FIG. 1 includes a base 10 on which a plurality of joint clips 3 attached to the horizontal streaks 2 are arranged. The base 10 is formed of a long member having a flat surface, and an elongated flat plate 12 is fixed to the upward flat surface portion 11 along the length direction thereof. Further, a plurality of protrusions 1 are provided on the flat plate 12 at a certain interval.
3 are arranged in a row so as to protrude upward.

The projections 13 are used to penetrate the vertical streak gripping portion 4 of the joint clip 3 and lock the same.
The distance between the projections 13 is set equal to the pitch of the vertical stripes 1 arranged in parallel. The projection 13 has a columnar shape and has a diameter slightly smaller than that of the vertical stripe, so that the joint clip 3 can be easily attached and detached.

At one end of the base 10, a wall 14 perpendicular to the arrangement direction of the projections 13 is provided. This wall 14
Defines the attachment positions of the joint clips 3 locked to the respective projections 13 and the horizontal streaks 2 to which these are attached. When the horizontal streaks 2 are arranged on the base 10 while abutting against the wall portions 14, the horizontal streaks 2 , Each joint clip 3 is arranged at a predetermined position. The wall 14 is movable in the direction in which the projections 13 are arranged, and
It is also possible to shift the mounting position of the joint clip 3 with respect to, while keeping the pitch constant.

On one side of the base 10, link mechanisms 20 are fixed at two places separated from each other. Link mechanism 20
2 is a booster in which two links 21 and 22 are combined as shown in FIG. 2. When the top of one link 21 which is an input end is pressed down, a significantly doubled force is applied. It can be taken out from the output end of the other link 22. The link mechanisms 20 are fixed side by side with the output end protruding above the base 10 and the input end protruding in the opposite direction.

One link 21 which is an input end of both link mechanisms 20 is connected to each other by a bar member 23, and a handle 24 is attached to the bar member 23. The link mechanism 20 can be operated simultaneously.

The output ends of both link mechanisms 20 are connected by a long member having substantially the same length as the flat plate 12. This member is a joint clip 3 arranged on the base 10.
The pressing member 30 presses the horizontal streaks 2 toward the base member 10 and is located above the flat portion 11 of the base 10.
Is operated to move toward and away from the base 10.
At this time, when the pressing member 30 is moved toward the base 10, the pressing member 30 descends toward the horizontal streak grip portion 5 of the joint clip 3 locked to each projection 13.

The joint clip 3 is attached to the horizontal streak 2 using the joint clip attaching device constructed as described above.
The work procedure for mounting will be described. First, the projection 13 is inserted through the vertical streak gripping portion 4 of the joint clip 3 and arranged so as to be locked. At this time, the opening 5a provided in the horizontal streak 5 is directed upward.

Next, as shown in FIG. 3, the horizontal streak 2 is arranged on the opening 5a of the horizontal streak 5. At this time, one end of the horizontal streak 2 abuts against a wall 14 provided at an end of the base 10 so that the mounting position of each joint clip 3 with respect to the horizontal streak 2 is accurately set.

Next, as shown in FIG. 4, the handle 24 is operated to lower the pressing member 30 toward the base 10 to press the horizontal streak 2 from above. Here, since the opening 5a of the horizontal streak gripper 5 is narrowed, the pressing member 30 is further lowered against the elastic force of the horizontal streak gripper 5 so that the horizontal streak 2
Is pushed into the inside of the horizontal muscle grip 5. Lateral streaked 2
Is held inside while pushing and expanding the horizontal streak portion 5.

Finally, the handle 24 is operated in the reverse direction to separate the pressing member 30 from the base 10, and then the horizontal streak 2 is pulled out from the projection 13 by pulling out the vertical streak grip 4 of the joint clip 3 from the base 10. When taken up from, a plurality of joint clips 3 are attached to the horizontal streak 2 at equal intervals.

By performing the work of attaching the joint clip 3 to the horizontal streak 2 as described above, a plurality of joint clips 3 can be attached to one horizontal streak 2 at a time. Can be greatly reduced. In addition, the operator does not need to use tools such as pliers, and the link mechanism 20 allows the pressing member 3
Since 0 is operated, the operation of the apparatus is labor-saving, the physical load on the worker is reduced, and the work efficiency is improved. From these facts, a significant improvement in productivity can be expected. Further, the mounting accuracy of the joint clip 3 is increased, and the joint clip 3 can be mounted at an accurate position with respect to the horizontal streak, so that unnecessary work such as correction of the mounting position on the site is not required.

Furthermore, if a driving mechanism such as an air cylinder or a hydraulic cylinder is combined with a link mechanism as a means for moving the pressing member 30, the apparatus is automated, so that the physical load on the worker is drastically reduced and the working efficiency is reduced. In addition to further improvement, further improvement in productivity is expected.

In the present embodiment, the pitch between the joint clips cannot be changed. However, the protrusions are densely arranged on the base, and a protrusion having an appropriate pitch is selected from these and the joint clip is selected. By arranging, it is also possible to freely change the attachment position to the horizontal streak. Further, a configuration in which the pressing member is directly moved by the drive cylinder without using the link mechanism, or a configuration in which the pressing member is moved by combining another transmission mechanism may be employed.

[0024]

As described above, according to the joint clip attaching device according to the first aspect, a plurality of joint clips can be attached to one horizontal streak at a time. The time can be shortened and a significant improvement in productivity can be expected. Further, since the joint clip can be mounted at an accurate position with respect to the horizontal streak, it is not necessary to perform extra work such as correction of the mounting position on site, and the work efficiency on site can be improved.

According to the joint clip attaching device of the second aspect, a link mechanism is employed as a means for moving the pressing member, and the operation of operating the link mechanism to push the horizontal streak into the horizontal streak gripping portion with a small force can be performed. Can do it,
The operation of the apparatus is labor-saving, the physical load on the worker is reduced, and the working efficiency can be improved.

According to the joint clip attaching device of the third aspect, the operation of pushing down the pressing member is automated, so that further improvement in productivity is expected and the physical load on the operator is eliminated. Can be.
