結金具に関する。[Detailed description of the invention] [Industrial application field] This invention has one end connected to a concrete formwork,
A pair of flat connecting members whose other ends are formed with connecting means for holding the concrete formwork at a predetermined interval, and the engaging means of the flat connecting members are inserted, and the connecting members and the connecting members are inserted. The present invention relates to a concrete form connection fitting comprising a wedge-shaped tightening member inserted into a connecting member.

Various types of concrete formwork connecting fittings for connecting a pair of concrete formworks to each other are provided. When the distance between these pair of concrete forms is relatively long, a U-shaped cross section is used as the connecting fitting for strength reasons. However, when the interval between concrete forms is relatively short, a plate-shaped connection fitting is sufficient in terms of strength, so a plate-shaped connecting fitting is used, which can be made relatively easily. However, the spacing between concrete forms used for pouring concrete varies widely, and it is therefore desirable to adjust the length of the connecting fittings.

Rod-shaped connecting fittings themselves are strong against bending moments in any direction, so they can be connected relatively easily, but flat connecting fittings are easy to bend in a direction perpendicular to the plane of the flat plate. When the connecting fitting is attached to a concrete formwork, the plane of the flat connecting fitting is oriented horizontally, so the strength against bending moment is relatively weak. Therefore, when adjusting the length, the connecting member tends to be weak.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a flat plate-shaped concrete formwork connecting fitting that has a simple structure, can be easily adjusted on site, is strong in terms of strength, and can be adjusted in length.

In the concrete form connection fitting according to the present invention, the connecting member has a channel shape, the flange portion thereof has a long hole into which the tightening member is inserted, and the engaging means formed in the connecting member includes:
One of them is a plurality of convex portions formed at regular intervals in the longitudinal direction, and the other is a plurality of concave portions that engage with the convex portions. The attached members are engaged with each other.

Therefore, at the site, the convex part of one connecting member is placed on the web part of the connecting member so that the convex part of the other connecting member engages with the concave part, and the positions of the recessed part and the convex part to be engaged are determined at the site. The length can be adjusted by shifting the length, and then the tightening member can be inserted into the elongated hole and tightened. When the tightening is completed, the concave portion and the convex portion of both flat connecting members are engaged, and the lower part is the web portion of the channel-like connecting member.
Since the upper part is engaged with the tightening member, it can sufficiently withstand bending moments.

It is possible to obtain a flat plate-shaped connecting fitting that is easy to use and has sufficient strength.
