某大型商业中心钢管混凝土柱施工技术

Some large-scale business center steel pipe coagulation earth pyramid construction technology

钢管混凝土柱是在圆形钢管内浇灌混凝土形成的组合结构构件,它充分利用了混凝土受压性能好和钢管韧性、塑性好的优点,使管内混凝土受三向约束,充分发挥了混凝土的作用,提高了结构构件的承载能力、抗震能力。本文通过工程实践,对钢管混凝土柱施工技术作了详细阐述。

The steel pipe coagulation earth pyramid is the built--up section component which the concrete forms in the circular steel pipe, it has used the concrete bearing performance fully good and steel pipe toughness, the plastic good merit, causes in the tube the concrete three to the restraint, has played the concrete role fully, sharpened the structural unit bearing capacity, earthquake resistance ability. This article through the project practice, has made the detailed elaboration to the steel pipe coagulation earth pyramid construction technology.
