摘要

PROBLEM TO BE SOLVED: To provide a concrete mold for steel tower foundation and a construction method of steel tower foundation concrete that curtail construction period and reduce costs.;SOLUTION: A foundation construction hole 1 is formed. A bottom end of a main leg material 3 is disposed at a bottom part of the foundation construction hole 1, such that the main leg material 3 extends in a vertical direction. A concrete mold receiving frame 10 is installed at the bottom part of the foundation construction hole 1, so as to surround the bottom end of the main leg material 3. A columnar body concrete mold 20 is provided in a top part of the concrete mold receiving frame 10, so as to surround the main leg material 3. A cover material 30 is supported by the top part of the concrete mold receiving frame 10 and an inner wall part of the foundation construction hole 1, a concrete placement port is opened, and the foundation construction hole 1 is closed by the cover material 30 at a location between the top part of the concrete mold receiving frame 10 and the inner wall part. Concrete is placed inside the foundation construction hole 1, from the concrete placement port to a height of the cover material 30.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
