Apartment remodeling construction method for construction duration reduction
The present invention relates to an apartment house remodeling framework construction method for shortening a construction period using a top-down method. According to the present invention, during the remodeling construction of an apartment house, one side of a core part to be extended is supported with a pillar and the other side of the same is joined to an old framework to deliver a load, and, accordingly, a ground floor is pre-constructed through a top-down method during the excavation of a car park in the extended core part, and, additionally, an upper floor core framework is constructed with steel frames such that the construction period can be additionally shortened. According to one advisable embodiment of the present invention, the apartment house remodeling framework construction method includes the following steps of: (a) removing a partial old framework of an existing structure, and then, constructing a retaining wall; (b) performing bed excavation on the outside of the retaining wall up to a predetermined depth, and extending an existing foundation up to an upper part of the retaining wall to place a new foundation of an extension part; (c) constructing a pillar on a position spaced a predetermined distance apart toward the outside of the retaining wall in a basement part, and excavating the basement part to install a steel girder; (d) performing a basement excavation and lower floor top-down method sequentially in the basement part, and then, installing a steel frame structure up to a lower floor part of a predetermined height in a ground part; (e) constructing a rebar concrete frame on floors, which are higher than the lower floor part of the predetermined height, to an upper part, while constructing a steel frame rebar concrete frame including the existing steel frame structure up to the lower floor part of the predetermined height, and forming a basement structure on a basement floor through a top-down method; and (f) performing finishing construction work from a part where the framework has been finished.
본 발명은 공동주택 리모델링 공사시 증축되는 코어부의 한쪽은 기둥으로 지지하고 다른 한쪽은 구골조와의 접합을 통해 하중을 전달하여 신축코어부 주차장 굴착중에 지상층 공사를 탑다운으로 선시공하며, 추가로 상부층 코어 골조의 형식을 철골로 시공하여 추가적인 공기단축이 가능하도록 하는 탑다운공법을 이용하여 공기단축이 가능한 공동주택 리모델링 골조공사방법에 관한 것이다. 본 발명의 바람직한 일 실시예는 공동주택 리모델링 골조공사방법에 있어서, (a) 기존 구조물의 일부 구 골조를 철거 후 흙막이 벽체를 시공하는 단계; (b) 흙막이 벽체의 외측에 일정 깊이까지 터파기하고 흙막이 벽체 상부까지 기존 기초를 연장하여 증축부의 신설 기초를 타설하는 단계; (c) 지하부분은 흙막이 벽체의 외측으로 일정거리 이격된 위치에 기둥을 시공하고, 굴착하여 철골보를 설치하는 단계; (d) 지하부분은 지하굴착 및 하부층 역타방식으로 차례로 시공을 진행하고, 지상부분은 철골구조를 소정 높이의 저층부까지 설치하는 단계; (e) 상기 소정 높이의 저층부를 초과하는 층은 철근콘크리트조를 상부로 시공하면서, 소정 높이의 저층부까지는 상기 기설치된 철골구조를 포함한 철골 철근콘크리트조로 시공하고 지하층은 지하 구조물을 역타로 형성하는 단계; (f) 골조가 끝난 부분부터 마감공사를 진행하는 단계;를 포함하여 이루어진다.
