Exterior building structure using unit integrated with insulation

An exterior building structure using a unit integrated with insulation, the exterior building structure (1) fixing an insulation-integrated unit (100) to an outer wall (W) of a building, the exterior building structure (1) comprising:

• a plurality of insulation-integrated units (100) each comprising a frame (110), a functional member (150) fixed to the frame (110), and an insulation member (160), the plurality of insulation-integrated units (100) being sequentially arranged vertically and horizontally;
• a plurality of horizontal insulation units (200) each comprising a hollow horizontal frame (210) and a horizontal insulation member (220) provided inside the horizontal frame (210), formed into a horizontally long shape to block heat transfer through a gap between the insulation-integrated units (100) that are vertically adjacent to each other, and supporting an upper end of a lower insulation-integrated unit and a lower end of an upper insulation-integrated unit of two vertically adjacent insulation-integrated units of the insulation-integrated units (100) while being fixed to the outer wall (W) to be vertically spaced apart from another horizontal insulation unit;
• and
• a plurality of vertical insulation units (300) each comprising a hollow vertical frame (310) and a vertical insulation member (320) provided inside the vertical frame (310), formed into a vertically long shape to block heat transfer moving via a gap between the insulation-integrated units (100) that are horizontally adjacent to each other, and fixing the horizontal insulation units (200) while being fixed to the outer wall (W) to be horizontally spaced apart from another vertical insulation unit.
