Abstract:
PURPOSE: To secure mounting by providing a center guide for mounting, by filling in a material that can be easily removed, and by forming a sleeve tube out of elastic material.
CONSTITUTION: A center guide 3 for mounting is provided, and the guide is colored to facilitate the discrimination for use. The flowing-in of concrete into a sleeve tube 1 is prevented, and a material that can be removed after a mold is deconstructed, is filled in, so as not to break the sleeve tube 1, and the sleeve tube 1 is formed out of elastic material. A joint hole is provided on the end surface of the center guide 3, and is connected through a joint pin. Construction can thus be facilitated.
