Separable integrated type vibration isolator

A separable integrated type vibration isolator comprising:

• a plurality of divided vibration isolator units comprising casings having accommodation spaces formed open on tops thereof in such a manner as to side plates and bottom plates thereof to be extended horizontally to casing connection spaces and reinforced concrete comprising reinforcing bars arranged in the accommodation spaces and the connection spaces and concrete cast in the accommodation spaces;
• casing connection parts for connecting the casings of the plurality of divided vibration isolator units to each other so as to maintain a state where the connection spaces of the plurality of divided vibration isolator units are connected to each other;
• reinforcing bar connection parts for connecting the reinforcing bars exposed to the connection spaces of the neighboring divided vibration isolator units to each other;
• fillers adapted to be cast in the connection spaces where the plurality of divided vibration isolator units is connected to form reinforced concrete;
• and
• shear keys disposed vertically on the bottom plates of the casings to prevent separation of the concrete, each shear key comprising:
• a post fixed vertically to the bottom surface of the corresponding casing by means of welding;
• and
• a head located on top of the post and having an expanded diameter or width from the post,
• wherein the fillers have an elastic modulus of 50 to 200% of the concrete cast in the accommodation spaces.
