Patent ID: 7097146

Claim:
An anti-vibration platform for supporting a semiconductor equipment thereon, comprising: a plurality of top ball couplings, each of which having a truncated top, each said top coupling being provided at a spherical surface with a plurality of internally threaded holes, and at said truncated top with at least one internally threaded hole; a plurality of bottom ball couplings, each of which being provided at a spherical surface with a plurality of internally threaded holes; a plurality of rigid connecting bars, each of which including a barred body having two externally threaded rods provided at two free ends thereof; said rigid connecting bar being adapted to connect at said two free ends to two said bottom ball couplings, two said top ball couplings, or one said bottom and one said top ball coupling by screwing said externally threaded rods into said internally threaded holes on the spherical surfaces of said ball couplings; and a plurality of vertical supports, each of which including a steel pipe and two externally threaded rods provided at two free ends of said steel pipe; and said vertical support being adapted to extend between two vertically corresponding top and bottom ball couplings by screwing said externally threaded rods into said internally threaded holes provided on the spherical surfaces of said ball couplings; said platform being covered at a bottom and all four sides thereof with steel plates, and the sides of said platform adjacent to a concrete foundation of said platform being provided with externally threaded rods that are extended from said top and said bottom ball couplings adjacent to the concrete foundation through said steel plates into said concrete foundation.
