PURPOSE: A panel connection structure of a complex window is provided to prevent a thermal insulation panel from being separated in a horizontal direction by stably connecting the thermal insulation panel to an inner frame. CONSTITUTION: A panel connection structure of a complex window includes an outer panel (100) and an inner panel (200). A pair of thermal insulation panels (300) symmetrically encloses the outer circumference of an inner frame (210) connected to thermal insulation materials and an outer frame (110) of the outer panel so that the inner panel insulates the indoor of the structure. A connection protrusion (220) is formed on both sides of the rear end of the inner frame, and a pair of fixing protrusions is formed on the center of the front end by being separated from each other so that an insertion groove (240) is formed. A connection groove corresponding to the connection protrusion is formed on one end of the thermal insulation panel, and an insertion unit (340) press-fitted to the insertion groove is formed by being bent on the other end. |
