AUTOMATIC ADJUSTMENT DEVICE AND SYSTEM OF OUTRIGGER STRUCTURES TO RELEASE ADDITIONAL STRESS, AND METHOD THEREOF

摘要

A joint structure of an outrigger and an external column for a damper having an automatic control function is provided to prevent the transfer of applied stress caused by differential shortening by absorbing the differential shortening between a core wall and an external column automatically using a displacement housing device. A joint structure of an outrigger and an external column for a damper having an automatic control function is formed for preventing the transfer of applied stress caused by differential shortening between an end of an outrigger and an external column to an external column by having a displacement housing device between an end(2) of an outrigger(1), and upper and lower brackets(21) attached to an external column(20) integrally, expanding or contracting the displacement housing device according to the displacement of the end of the outrigger and absorbing the displacement between the end of the outrigger and the upper and lower brackets of the external column, that is, the differential shortening between a core wall and the external column automatically. The displacement housing device is composed of a hydraulic cylinder(30) and installed between the bracket and the end of the outrigger, wherein if one of the hydraulic cylinders is put under pressure to increase in pressure, the increased pressure is decreased gradually as time passed and the other hydraulic cylinder is put under the pressure corresponded to the reduced pressure, so that the other hydraulic cylinder is expanded.
