る。As a connecting tool for connecting concrete formwork, basically required items are as follows.
It is possible to firmly and reliably maintain the formwork connection state, and to perform work such as attaching and detaching to and from the formwork and carrying the formwork connecting tool easily and efficiently. In order to firmly and reliably maintain the formwork coupled state, it is preferable that the sandwiching portion sandwiching the crosspiece has sufficient strength and that the sandwiching surface is as close to the face plate as possible. This is more effective in preventing the face plate from opening due to the clamping of the holding portion. When the face plate side is opened, the face composed of multiple adjacent face plates is no longer a perfect plane,
Unevenness occurs on the concrete surface molded by the formwork.

構成されていることが望ましい。In recent large-scale construction work, it is often necessary to connect a large number of concrete forms in a short time. In order to improve work efficiency, the weight should be as light as possible so that many formwork connectors can be transported at one time. Also, the work of attaching and fixing the connecting tool to the formwork is
It is desirable to complete with bare hands as much as possible. Even if the contact parts of the formwork are not in close contact with each other even after the temporary attachment of the connecting tool and there is clearance, it is only necessary to give a slight impact by a plastic hammer or the like. In addition,
In this case, the hammer is preferably hit so that the hitting surface is devised so that it is easy to hit and there is no risk of accidentally hitting a mold or the like other than the connector.

け低くなっている。Conventional concrete formwork connectors have not fully met these needs. That is, most of the conventional mold connector of this type is made of metal and is heavy. Even if it is incorporated in the formwork, the formwork itself is made heavy, and there is a similar problem. FIG. 7: is explanatory drawing (side view) which shows the connection effect at the time of connecting the concrete formwork by the conventional example of FIG. In order to reduce the weight of this connecting tool, the one-side sandwiching portion 31 and the other-side sandwiching portion 32 may be resin molded bodies. However, as shown in FIG. 7, an effective sandwiching surface (indicated by a dotted line in the figure). The pressure portion T 2 ) shown by hatching is small,
Moreover pressurized portion T 2 from the face plate 12a (12b) a distance L 2 is large, the effect of preventing the opening of the face plate side is much lower.

る。Further, in the work of sandwiching the crosspiece in the sandwiching part, the slope for smoothing the pushing is only on the other side sandwiching part 32 and not on the one side sandwiching part 31, so that the pushing work is very smooth. Not. Moreover, when hammering in with a hammer, the striking direction is not perpendicular to the face plate but is slanted, so there is a possibility that the surface of the crosspiece between the two holding parts will be hit and damaged due to ergonomic considerations. If the crosspiece is damaged or deformed, the concrete forms will be poorly adhered to each other when they are reused, and the life of the formwork will be shortened.
