<p>PURPOSE:To prevent a foundation inside from generating overheat and electrolytic corrosion, by separating a magnetic shield from a reinforcement buried in a building foundation so that a closed circuit cannot be formed by the magnetic shield and the reinforcement. CONSTITUTION:A scaffold 9 for fixing a magnetic shield frame is built through a lower flat surface and a side surface on casting foundation concrete through the lower side, and a beam 10 is fixed inside the magnetic shield on the scaffold 9. On the construction, turnbuckles or the like between a reinforcement 3 and the magnetic shield 5 are not needed, and there is not fear of circulating current being generated because the magnetic shield 5 is not connected to the reinforcement 3.</p> |
