<p>PURPOSE:To reduce vibration by planting a plurality of supports, penetrating through the upper slab, onto the lower slab of a building, while separating each other then mounting a common base thereon and securing the common base thereto thereafter mounting and securing a gas insulation switchgear integrally onto the common base through resilient supports. CONSTITUTION:A plurality of supports 7 are planted and secured vertically onto the slab of first floor in a building. The supports 7 are separated one another where one ends thereof penetrate through through-holes 8a made through the slab of second floor. A resilient body 9 is mounted in a gap between the through-hole 8a and the support 7. A common base 10 is mounted on the supports 7 at the second floor and secured thereto, and a base 12 is arranged to face with the common base 10 through a plurality of resilient support 11. A gas insulation switchgear 14 comprising a gas insulation circuit breaker 13 and the like is mounted integrally on the base 12 secured thereto.</p> |
