Description

[Detailed Description of the Invention] The present invention relates to an improvement of a U-clip used for assembling metal concrete formwork such as aluminum formwork or metal form.

First, a conventional U-clip will be explained, thereby clarifying the purpose of the present invention.

Fig. 1 is a perspective view of a conventional U-clip, and Fig. 2 is a perspective view showing the state in which the same is used. One end of the vertically rising portion 3 is raised vertically, and the upper end of the vertically rising portion 3 is bent horizontally and laterally so as to be positioned above the sandwiching portion 2 to form a lateral bent portion 4. .

To use such a U-clip 1, as shown in FIG. 2, first insert the horizontally bent portion 4 of the U-clip 1 into the U-clip hole 5b provided in the rib 5a of the metal formwork 5, 5'. Then, using this bent portion 4 as a fulcrum, use a hammer or the like to remove the rib 5a directly below it.
If they are inserted into the sandwiching part 2 while being overlapped, the metal forms 5 or 5 and 5' are fastened with the U clip 1 via the ribs 5a.

In addition, 5 is a flat form metal formwork,
5' indicates a corner angle member.

On the other hand, in order to perform demolding, each metal formwork 5, 5' is separated into pieces, and it goes without saying that the U-clip 1 must also be completely removed from the rib 5a and recovered.

In this way, removing the U-clip each time when demolding and reattaching it when assembling the mold takes a lot of effort, and also makes it troublesome to store and manage the disassembled parts.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
To provide a U-clip which can simplify work since it does not need to be removed from a mold when demolding.

However, according to the present invention, the purpose of the lever is to raise one end of the U-shaped clamping part and bend the upper end of the raised part in the lateral direction on the clamping part side. This is achieved by forming the bent portion to be long so that its tip protrudes more than the pinching portion, and providing a through hole for inserting the locking pin near the tip.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the U-clip of the present invention. The U-clip 6 is made of iron, and one end of a U-shaped clamping part 7 is raised vertically, and the vertically rising part 8 is raised vertically. Fold the upper end horizontally to form a horizontal bent part 9
It is the same as the conventional U-clip 1 in that it is formed, but this horizontally bent part 9 is formed longer than the conventional one so that the tip thereof protrudes more than the pinching part,
A through hole 11 for inserting the locking pin 10 was provided near the tip thereof. A normal nail can be used as the locking pin 10.

Next, how to use the U-clip 6 of the present invention when constructing a column will be explained.

As shown in FIG. 4, the U-clip 6 of the present invention is used at the corner of a metal formwork. In other words, the corner angle member 5' of the metal formwork
For fastening the flat form formwork 5 to each other, an ordinary U clip may be used to fasten the flat form formwork 5 to each other.

The first setting method of the U clip 6 is the conventional U clip 6.
It is similar to a clip, except that the locking pin 10 is inserted into the through hole 11 at the end of the lateral bent portion 9 that protrudes through the U clip hole 5b of the rib 5a, and this bent portion 9 is inserted into the hole 5b. Make sure you don't get out of it.

In this manner, when demolding, only the clamping part 7 of the U-clip 6 of the present invention set in the corner of the formwork can be struck with a hammer to remove it from the rib 5a.
As shown in the figure, the flat form frame 5 and the corner angle member 5' become loose, but the angle member 5' has a locking pin inserted near the tip of the long bent part 9. 10, and it never leaves U-clip 6, so it never leaves completely.

As shown in Figure 6, if the upper part of the metal column form A with only the corners loose is lifted up with a crane, etc., the column form will be formed in about 10 seconds as shown in Figures 7 and 8. Frame A slips out and only the constructed column B remains.

In order to erect a column on a slab, concrete slabs are poured, markings are done, column reinforcing bars are hung, and formwork is constructed around it, but as shown above, only the corners are loosened and lifted. Formwork A can be hung as is, and U-clip 6 is attached as is, so it can be completely set up just by hitting it with a hammer, and formworks 5 and 5' are fastened together and reassembled to the original solid formwork. You can do this with just one touch.

As mentioned above, the U-clip for metal formwork of the present invention does not need to be removed from the formwork when demolding the formwork.
In addition, since work can be carried out without completely separating the formworks while they are loosely connected to each other, the metal formwork itself does not come apart, making it easy to use and simplifying the work.
