Title: Double wall coupling tool

Abstract: A coupling tool for a double wall is proposed which makes it possible to join an inner and an outer wall together without selecting places while ensuring a sufficient joint strength. The coupling tool is formed by an anchor formed by superposing two metallic plates so as to be spreadable, and a wire of a required length mounted to one end of the anchor. The wire is fixed to the anchor so as to protrude from an end opposite to the tip of the anchor. Since the anchor can be driven into the inner wall at any position, the outer wall can be fixed to the inner wall by use of the coupling tool without selecting places and number.
