贵阳市行政中心大楼型钢混凝土施工工艺

研究目的:由钢筋混凝土包裹型钢做成的结构被称为型钢混凝土组合结构(steel re inforced concrete com-posite structures)。该技术是近期建设部推广应用的十项新技术、新工艺之一,本文以贵阳市行政中心大楼型钢施工为例,介绍型钢的设计、施工工艺。研究方法:通过对型钢结构的组合方式、设计,提出具体的施工方案,现场安装措施、关键工序控制,来保证型钢混凝土质量。研究结果:总结出了型钢混凝土结构的施工工艺,提出了连接、吊装、检查、改进等方法对施工有一定参考作用。研究结论:型钢混凝土结构,优良的结构性能,达到构件截面积小,对于建筑物而言,可以增大跨度,增加使用面积和层净高,其经济效益可观,将会越来越广泛地应用于工业与民用建筑中。

Construction Technique of Steel Concrete for Guiyang Municipal Centre Building

Research purposes: The sturcture made of reinforced concrete and parcel steel is called steel reinforced concrete composite structure,which is one of ten new technologies and techniques to be applied currently and widely approved by Ministry of Construction. Taking structural steel construction of Guiyang Municipal Centre Building as example,the introduction is given to the design and construction technique of structural steel.Research methods:Based on the composite way and design of steel structure,the construction procedure,measures for site installation and control of key processes are presented in order to ensure quality of steel concrete.Research results:The construction technique of steel concrete structure is summed up and the methods for connection,hanging and instaalation,inspection and improvement are put out for connection,hanging and installation,inspection and improvement are put out for providing reference to construction.Research conclusions:Steel concrete structure has a good structural performance with a small section of component and increasing span,usable area and net floor hieght of building,thus notable economic benefits can be obtained and steel concrete structure can be more and more widely applied in industrial and civil buildings.
