Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reinforcing bar fixture of a welding jig that holds opposing reinforcing bars in a predetermined position in a reinforcing bar welding process for reinforced concrete structures.

[Prior Art] Regarding a fixing device for a welding jig, there is a device disclosed in Japanese Utility Model Publication No. 84197/1987 by the inventors of the present invention. FIG. 3 is a front view of this invention, and FIG. 4 is a side view. In the figure, 1 is a main body fixing box that shields the welded part, 2 is a lid fixing box that is combined with the main body fixing box 1 by sandwiching the reinforcing bars 10, and 3 is a main body fixing box 1.
4 is a protruding support plate engagement screw provided on the main body jig support plate 3, 5 is a lid jig support plate, and its base is attached to a connecting hinge 6. Therefore, an engagement hinge 7 is provided at the tip end, which is connected to the main body jig support plate 3 and can be raised and lowered. Further, a support plate tightening screw 8 is provided in the middle part of the lid jig support plate 5, and a pressing metal fitting 9 is attached to the tip part.

Next, this effect will be explained.

At the reinforcing bar joint, a main body jig support plate 3 provided at one end of the main body fixing box 1 is connected to one reinforcing bar 10.
Then, the lid jig support plate 5 is rotated by the connecting hinge 6 to surround the reinforcing bars 10, and the engagement hinge 7 provided at the tip of the lid jig support plate 5 is raised and the tip is rotated. It is hooked onto a support plate engaging screw 4 provided at the tip of the main body jig support plate 3. After that, turn the support plate tightening screw 8 and insert the reinforcing bar 10 through the pusher fitting 9.
By pressing and tightening to the main body jig support plate 3,
The reinforcing bars 10 are fixed to the main body fixing box 1. Similarly, the other reinforcing bar 10 is surrounded and fixed by the main body jig support plate 3 and the lid jig support plate 5 on the other side. By thus fixing the respective reinforcing bars 10 to both sides of the main body fixing box 1 and further combining the lid fixing box 2 to the main body fixing box 1, the joints of the reinforcing bars 10 can be shielded for welding.

[Problems to be solved by the invention] In the conventional welding jig fixture as described above, in order to surround the reinforcing bar 10 with the main jig support plate 3 and the lid jig support plate 5, it is necessary to engage The work of raising and lowering the hinge 7 and hooking it to the support plate engaging screw 4 is required, which requires manpower. Particularly when there are a large number of reinforcing bars and the spacing between the reinforcing bars is narrow, the work becomes difficult and requires a lot of time and effort. Further, when the support plate tightening screw 8 is turned and the reinforcing bar 10 is pressed through the pushing metal fitting 9, the pushing metal fitting 9 rotates, causing a problem in the pressure applied to the reinforcing bar 10.

[Means for Solving the Problems] The present invention was made to solve such problems. A fixing bracket that is connected to the plate by a connecting hinge to form a square frame, a support plate tightening screw with a pusher fitting at the tip that slides inside the square frame, and a hook-shaped screw to hook the fixing bracket. To provide a fixture for a welding jig, which is provided with a latch which is formed and attached to a main body jig support plate so as to be rotatable through a small angle with a spring plate.

[Operation] When the rectangular frame surrounding the reinforcing bars is pressed against the main body jig support plate, the latch fitting rotates and automatically latches the rectangular frame. Next, turn the support plate tightening screw,
The pushing metal fitting slides within the rectangular frame and presses and fixes the reinforcing bar against the main body jig support plate.

[Embodiment] FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a side view. In the figure, reference numeral 11 denotes a hook-shaped latch, which is connected to a mounting bracket 1a provided on the main body fixing box 1 by a spring plate 12 attached to the back. Note that 13 is a hook plate attached to the top of the hook 11. Reference numeral 14 denotes a rectangular frame body having a U-shaped cross section, one side of which is connected to the main body jig support plate 3 by a connecting hinge 6, and the other side formed with a claw for hanging onto the latch fitting 11. It is further provided with a pressing metal fitting 9 that slides inside the frame, and this pressing metal fitting 9 is adapted to be moved up and down by a support plate tightening screw 8. The other symbols are the same as those in FIGS. 3 and 4 above.

Next, this effect will be explained.

The main body fixing box 1 is set at the joint of the reinforcing bars 10 so as to span both reinforcing bars, the rectangular frame 14 is rotated around one of the reinforcing bars 10, and then pressed against the main body jig support plate 3, the latch fitting is attached. 11 is spring plate 1
2 to rotate a small angle and automatically lock the rectangular frame 14. After that, when the support plate tightening screw 8 is tightened, the pressing metal fitting 9 comes into contact with the reinforcing bar 10 while sliding inside the rectangular frame 14, and tightens and fixes the reinforcing bar 10. Thereafter, by performing the same operation on the other reinforcing bar 10, the other main body jig support plate 3 and the rectangular frame 14 are tightened and fixed.

When removing it, first loosen the support plate tightening screw 8, then pull the handhold plate 13 toward you, and the latch 11 rotates to release the rectangular frame 14.

[Effects of the invention] In the reinforcing bar fixing device according to the present invention, the rectangular frame for surrounding and gripping the reinforcing bars can be set with a single touch, so there is no need to put your hand into the gap between the reinforcing bars and hang it, unlike conventional methods. It was no longer necessary. In addition, since the pusher metal slides within the frame, the pusher metal will not rotate even when the support plate tightening screw is turned, ensuring secure tightening. Summer. This had a significant effect in reducing the labor and time required to secure and hold the welding jig to the reinforcing bars.
