摘要
以华夏文化旅游二期鲸豚馆屋面网架为例,根据工程特点和现场实际情况,采用分步顶升,逐层拼装,直至具备整体顶升条件后,顶升至设计标高的施工方法,研究液压顶升技术在网架拼装场地狭促中的应用,发现液压顶升技术减少了高空焊接球散拼的难度,保障了施工安全。
The Huaxia Culture Tourism two whale Museum roof truss as an example, according to the engineering characteristics and the actual situation, step by step lifting, layer by layer assembly, until with integral lifting conditions, roof construction method to design elevation, application of hydraulic lifting technology in grid installation site in that cramped, hydraulic lifting technology reduces the overhead welding ball assembly difficulty, ensure construction safety.
