The present invention relates to a composite impact-absorbing system which perfectly absorbs vibration produced by an impact of a seismic wave in a vertical and a horizontal direction to prevent damage and deformation of a pipe. The composite impact-absorbing system comprises: a first insert plate (104) installed in a ceiling formed by depositing concrete; a second insert plate (106) installed in the ceiling formed by depositing concrete and separated from the first insert plate (104); a horizontal plate (108) separated from the first insert plate (104) and a second insert plate (106); a first screw bar (110) vertically installed on a lower end of the first insert plate (104); a first absorbing means (112) installed on an upper surface of the horizontal plate (108) to face the first screw bar (110) to absorb an impact of a seismic wave; a first connection unit (114) screwed and mounted between one end of the first screw bar (110) and one end of the first absorbing means (112); a second screw bar (116) vertically installed on a lower end of the second insert plate (106); a second connection unit (118) screwed and mounted on an upper portion of the second screw bar (116); a second absorbing means (120) installed on the upper surface of the horizontal plate (108) to face the second screw bar (116) to absorb an impact of a seismic wave; and a third connection unit (122) screwed and mounted between one end of the second screw bar (116) and one end of the second absorbing means (120). |
