Title:
MAGNETIC SHIELDING AGAINST MAGNETIC FIELD GENERATING SOURCE, AND CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JPH1174672
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform magnetic shielding with a magnetic shielding panel efficiently. SOLUTION: Relating to magnetic shielding against magnetic field generating source wherein a magnetic field generating source is magnetic-shielding with magnetic shielding panels 1 and 2 allocated, a magnetic shielding layer wherein a plurality of magnetic shielding panels 1 and 2 are laminated is provided at a border part of the magnetic field generating source 6, while the number of laminated sheets at a center part of the magnetic shielding panels 1 and 2 is larger than its peripheral part. The border part of the magnetic field generating source 6 falls in a floor part of the next higher floor of an electric power facility provided in a facility room 5, etc. Relating to its construction method, the magnetic shielding panels 1 and 2 are so laminated in plural numbers as the number of sheets at the center part is larger than the peripheral part of the floor part, a step between the center pert and the peripheral part is covered with a presser bracket, and the presser bracket is fixed to a floor slab together with the magnetic shielding panels 1 and 2 using a tapping vis and an anchor from an upper surface.
