新建铁路哈大客运专线大连北站站房钢结构工程安装和施工技术

新建铁路哈大客运专线大连北站站房钢结构主要包括钢柱、商业夹层、CB-CK轴线张弦屋盖桁架3大部分。在考虑现场施工的不利因素,如现场铁路转线,冬季焊接施工条件差、焊接质量控制难、现场操作场地狭小等等的影响基础上,系统地总结了该项目钢结构的施工要点,详细阐述了钢结构施工的顺序、施工方法和关键技术。通过科学合理的施工组织解决了施工中的难题,保证了施工质量及工期。可为以后同类工程安装给予一定的借鉴。

Steel Erection and Construction Technology for New Railway Harbin-Dalian Special Passenger Line in Dalian North Station

The steel structure of Dalian North Station bulding of new Harbin-Dalian Special Passenger Line mainly includes steel columns , commercial mezzanine , and truss string roof between axis CB and CK.Considering the unfavorable factors in the construction process , such as on-site railway transfer , poor welding construction condition in winter , difficult to control the welding quality , small fields for on-site operation , and so on , this paper summarizes main points of the steel structure construction.In addtion , this paper introduces the steel structure construction sequence , construction method and key technologies.Appropriate construction organization will solve the problems in the construction process , it also ensures good construction quality and schedule.
