Zusammenfassung:	Provided are a lattice-type rib deck, a lattice-type arch rib deck, and a construction method thereof capable of improving a load supporting capacity to effectively control tensile cracks by effectively supporting girders and beams of a bridge and adjoining decks. The lattice-type rib deck includes outer haunch units formed to be integrated with both lengthwise ends and both breadthwise outer ends of a body unit and a lattice-type rib integrally formed between the outer haunch units to obtain recessed internal spaces (S) partitioned due to the block-out bottom surface of the body unit. The lattice-type arch rib deck includes lattice-type arch ribs integrally formed between the outer haunch units. 교량의 거더, 가로보 및 인접한 데크와 효과적으로 지지되도록 함으로서 하중 지지능력을 증진시켜 인장균열을 효과적으로 제어할 수 있는 격자형리브데크, 격자형 아치리브데크 및 그 시공방법에 관한 것으로서, 상기 격자형리브데크는 몸통부의 양 장변방향 단부와 양 단변방향 외측 단부 4변에 일체로 형성된 외측헌치부; 및 몸통부 저면이 블럭 아웃되어 홈 형태의 구획된 내측공간(S)을 확보할 수 있도록 외측헌치부 내측 사이에 일체로 형성된 격자형리브;를 포함하며, 격자형 아치리브데크는 외측헌치부 내측 사이에 일체로 형성된 격자형 아치리브를 포함하게 된다.
