DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member for efficiently and economically connecting a plurality of members and a connecting structure using the connecting member.

[0002]

2. Description of the Related Art Conventionally, in order to connect a plurality of members to be connected (connected members), usually, a connecting tool or a connected member is bent (see Japanese Utility Model Publication No. 22107/1990).
Alternatively, a technique of fixing with a fixing tool such as a screw has been used. A technique has also been used in which the connecting portions of the members to be connected are sewn to each other by a flexible member or a member formed in a spiral shape.

For example, when an expander metal is connected in constructing a reinforcing retaining wall on a slope, or when sheet piles are connected in a sabo work for a river or the like, a connected member (connected member) or a connected member. It has been necessary to bend the connecting members and connect them together, or to fasten each other with screws to connect them.

Further, when connecting a plurality of grid-like reinforcing members, there is known a connecting method in which a plurality of loop members provided on a connecting member are projected from gaps for alignment and a rod is inserted through the loop members. (See Japanese Patent Application Laid-Open No. 2-204526).

[0005]

However, such a conventional connecting tool and connecting structure require an operation for bending or screwing and a special tool therefor. At the site of construction work requiring simple work, there are problems in terms of workability and economy.

In the connecting member provided with the loop member, the connecting member main body and the loop member are formed separately, and the loop member is connected to the grid reinforcing member so as to protrude from the gap for alignment. Therefore, it cannot be said that the connection strength is necessarily sufficient for the external force or the like received from the grid reinforcing material as the connected member depending on the mode of using the grid reinforcing material.

An object of the present invention is to solve such a conventional problem, and requires a special tool for bending or tightening a member at a construction work site or the like. It is a structure that can easily and quickly connect the connected members without any problems, and the structure is simple and excellent in strength, according to the type, structure, dimensions, etc. of various types of connected members It is an object of the present invention to realize an economical connecting tool and a connecting structure which can be appropriately changed in design.

In addition, it is necessary to deform and connect the members to be connected in accordance with the circumstances surrounding the installation of the connecting members. For example, when laying the expander metal along the step surface of the slope, or when configuring a curved surface composed of a plurality of sheet piles, the connected members to be connected to each other are angled. It needs to be connected. It is an object of the present invention to provide a connecting tool and a connecting member that can flexibly cope with such a case without impairing the original rigidity and connecting strength of the connecting member.
