Vibration isolation structure using precast concrete shear-key block and anti-vibration pad, and method for controlling anti-vibration of structure using the same

摘要

In a structure which forms an upper structure and a lower structure divided by an anti-vibration pad for vibration isolation therein, since the concavo-convex type shear key is formed using the precast concrete shear-key block, the construction can be precisely performed according to the predetermined standard. Therefore, a vibration isolation structure using a precast concrete shear-key block and an anti-vibration pad which are capable of effectively blocking vibration and noise, and a constructing method thereof are provided.

1. A vibration isolation structure using a precast concrete shear-key block and anti-vibration pads, wherein the vibration isolation structure is divided into a lower structure and an upper structure by the anti-vibration pads for vibration isolation, comprising:
the lower structure configured to serve as a transfer floor structure or a foundation structure and formed by pouring and curing concrete; the upper structure formed on the anti-vibration pads by pouring and curing concrete; the precast concrete shear-key block arranged on the lower structure at a predetermined interval to restrict horizontal movement of the upper and lower structure, and the precast concrete shear-key block having shear studs formed to be perpendicular to a plurality of shear keys that protrude from the shear-key block, wherein the precast concrete shear-key block comprises:
a concrete body;the plurality of shear keys arranged to have a space from each other;the shear stud, correspondingly located below each of the shear keys and perpendicularly connected with a rebar arranged to form the lower structure and to transmit a shear force; anda transverse rebar and a longitudinal rebar transversely and longitudinally arranged in the concrete body; the anti-vibration pads are installed between upper and lower surfaces of the precast concrete shear-key block and between the shear keys, the anti-vibration pads having incompressible characteristics to absorb vibration in the upper and lower structure, wherein the shear studs of the precast concrete shear-key block are connected and integrated with the lower structure.
