STORAGE TYPE ASEISMIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a storage type aseismic device which rapidly appears in an earthquake and acts an aseismic function. SOLUTION: One of brace elements bifurcated in the longitudinal direction is arranged along the inside face of a column. A latching mechanism which positions the brace element in a containing state along the inside face of the column and release by a controller is provided. The other brace element is arranged along the inside face of a beam. A latching mechanism in which the brace element is positioned in a containing state along the inside face of the beam and released by a controller is provided. Joint connection mutually connected is installed at the free side end of each brace element. An earthquake detection sensor detecting an earthquake input of a building and a latch controller releasing the latching mechanism is set when the earthquake detection sensor detecting an earthquake input of the building and the latch controller releasing the latching mechanism when the earthquake detection sensor detects an initial micromotion are installed.
