JPS5938845Y2 - U-clip operating tool for formwork connection - Google Patents

Description

[Detailed description of the invention] The present invention relates to an operating tool for a U-clip for joining formwork, which is used for attaching and detaching a U-lip for joining steel formwork for concrete pouring used mainly in civil engineering and construction. .

FIG. 1 is a perspective view of concrete formwork joined by a U-clip, which explains the conventional method of operating the U-clip.

A through hole 3 is provided at a position corresponding to the joining of the joining outer peripheral frame 4 of the formwork 1 .

The U-clip 2 that connects the adjacent formworks 1 has a substantially U-shaped hook 2a at one end, and the other end is bent inward at right angles to form a feed-in end 2b. and is rotatably inserted into the through holes 3, 3.

Now, in the conventional method, when joining the adjacent formworks 1, 1 through the U clip 2Vc, the joining outer peripheral frames 4, 4 are inserted into the opening of the hook 2a, and the head of the hook 2a is inserted into the opening of the hook 2a. Noise was generated because the formwork was connected by extrapolation as if it were driven in.

2. Tightening by driving is not smooth and may cause the formwork to burn or damage the clip.

3. Workability is poor and standardization of work is difficult.

There were other problems.

The present invention eliminates the above drawbacks and provides a one-touch U
The object of the present invention is to provide an operating tool that can attach and detach a clip.

The operating tool of the present invention will be described below with reference to an illustrated embodiment.

As shown in FIGS. 2 to 4, the operating tool 5 includes a long handle frame 5
Four operating rods 5b are attached to the base end of the handle frame 5a in a direction parallel to the axis of the handle frame 5a via connecting portions 5c.

This operating rod 5b is made by bending a tanzaku template into an inverted U shape.
And, there is a gap of 5 in the center of the facing board.
d, and on the other hand, an interval 5eV'i formed by bending into an inverted U-shape, which is an interval that extrapolates the joint outer peripheral frame 4°4.

Therefore, each of the above-mentioned intervals 5d and 5e has a substantially cross shape, and the four fork-shaped operation rods 5b have the above-mentioned connecting portion 5C.
It is protruded so as to be located at the corner of the parallelogram.

Next, how to use this operating tool 5 will be explained.

The hook 2 of the U clip 2 is placed at the interval 5d on the split side.
The operating tool 5 is externally fitted onto the U-clip 2 by inserting and pinching the outer peripheral frames 4 and 4 at the other interval 5eK.

Next, focusing on the handle frame 5a and centering on the end 2b,
By the lever principle, the joint outer peripheral frames 4, 4 are rotated in the direction in which they are inserted into the opening of the hook 2a of the U-clip 2.

As a result, the formwork can be joined by the U-clip 2 without any difficulty.

When disassembling the formwork, the operating tool 5 may be rotated in the opposite direction to the above.

As described above, compared to the conventional method of driving the U-clip into the joint outer peripheral frame using a hammer or the like and inserting or separating it, the operating tool of the present invention applies the principle of lever to facilitate the attachment and detachment of the U-clip. There is no noise caused by the hammer or the like mentioned above, and there is no damage to the formwork or clips, and the workability can be improved.
