To impart shielding effects to an electromagnetic field generated in a thunder current flowing in a building structure and to prevent indoor equipment from being greatly influenced by a potential difference generated between upper and lower floor slabs caused by a thunder current.
In the equipotentiality of an important room in a building and a structure grounding mechanism, a metal body 6 is buried in a floor slab 1, and is connected electrically to a reinforcement 5 arranged in a mesh state with a connection line 7. A partition wall 3 has a backing light-weight steel frame 9 in a mesh structure, and the backing light-weight steel frame is electrically connected to the metal body with a fixing pin 8 driven into the metal body from a lower side runner 10, and grounded to the reinforcement of the floor slab through the connection line, thereby performing insulation while interposing an insulating material 13 between a partition wall, upper floor slab 2 and a stud 12.
