A fire spread prevention structure for a building using fireproof blocks, a construction method thereof, and a fireproof building thereby are disclosed. According to the present invention, the fire spread prevention structure for the building using fireproof blocks comprises fireproof finishing parts and fireproof blocks, wherein the fireproof finishing part includes a fire-retardant insulation material, a first fire spread prevention layer interposed between the fire-retardant insulation material and a second fire-retardant insulation material vertically or horizontally arranged adjacent to the fire-retardant insulation material, and a second fire spread prevention layer provided on the front surface or the rear surface of the fire-retardant insulation material. Therefore, the fire spread prevention structure for a building can effectively delay the spread of fire by preventing the spread of fire from indoors to outdoors through vulnerable areas, such as openings, in the event of a fire, blocking the flame or fire from spreading vertically in the building by moving to the insulation material inside the finish material, and minimizing direct contact with the exterior surface. 본 발명은 내화방염블록을 이용한 건축물의 화재확산 방지구조 및 이의 시공방법 그리고 이에 의한 내화건축물을 개시한다. 본 발명에 따르는 내화방염블록을 이용한 건축물의 화재확산 방지구조 및 이의 시공방법 그리고 이에 의한 내화건축물은 화재확산방지 구조는 내화마감부와 내화방염블록을 포함하고, 상기 내화마감부는 내화단열재와, 상기 내화단열재에 수직 또는 수평방향으로 인접하여 배열되는 제2내화단열재와의 사이에 개재되는 제1화재확산방지층과, 상기 내화단열재의 전면이나 후면에 구비되는 제2화재확산방지층을 포함하는 특징이 있는데 이에 의하면, 화재시 개구부 등 화재취약부위를 통해 화재가 실내에서 실외로 확산되는 경우에 화염이나 불꽃이 마감재 내부의 단열재에 옮겨붙어 건물의 수직방향으로 확산되는 것을 차단할 뿐만 아니라 외부 표면에 직접 닿는 것 또한 최대한 억제함으로써 화재의 확산을 효과적으로 지연시키는 효과를 발휘할 수 있다.
