The present invention relates to a hook-up type damper assembly structure and, more specifically, to a hook-up type damper assembly structure for discharging a hume gas from a duct to the outside, wherein the hume gas contains various gases and chemicals discharged from a semiconductor manufacturing process. A damper assembly according to the present invention comprises: a cylindrical hollow damper (11) having a flow path; a hopper (12) formed at one end of the damper (11), connected to a duct (20), and including an extended part (121) and a coupling part (122); a fastening part (13) formed at the other end of the damper (11); and a control blade (17) formed inside the damper (11), wherein the extended part (121) is extended to have a cross section larger than the cross section of the damper (11), and the coupling part (122) of which at least the part corresponding to the outer surface of the curved duct (20) has a border (S) formed into an extended curved surface with a height difference based on the cross section of the damper (11) and is fixed to the duct (20) by fastening pieces (25). |
