Construction method of square-sleeved circular steel tube stiff concrete column
The invention relates to a construction method of a square-sleeved circular steel tube stiff concrete column. Comprising the steps of construction of a concrete foundation bearing platform, shaping machining and hoisting of the steel pipe stiff column, positioning and installation of the steel pipe stiff column, installation of a steel reinforcement framework on the periphery of the steel pipe stiff column, installation of a square column formwork on the periphery of the steel pipe stiff column, installation of an outer hoop laitance collecting device, internal and external integrated pouring of the high-throwing self-compacting steel pipe stiff concrete column and concrete curing. The device has the beneficial effects that accurate positioning and mounting of the steel pipe stiff column are achieved through the devices such as the annular groove, the steel plate belt positioning ring, the positioning rib plate and the level bubble; a high-throwing self-compacting concrete technology is adopted, and integrated rapid high-quality pouring of concrete inside and outside the steel pipe stiff column is achieved; the steel formwork provided with the brackets and the self-adhesive rubber strips is adopted as a formwork supporting system of concrete outside the pipe, and the stability and the sealing performance of the formwork are improved; and by adopting an outer hoop laitance collection technology, the concrete laitance can be rapidly collected and recycled.
本发明涉及一种方套圆钢管劲性混凝土柱的施工方法，包括步骤：混凝土基础承台施工、钢管劲性柱定型化加工与吊装、钢管劲性柱定位安装、钢管劲性柱外围钢筋骨架安装、钢管劲性柱外围方柱模板安装、外套箍浮浆收集装置安装、高抛自密实钢管劲性混凝土柱内外一体化浇筑、混凝土养护。本发明的有益效果是：通过环形凹槽、钢板带定位环、定位肋板、水准泡等装置实现了钢管劲性柱的精确定位与安装；采用高抛自密实混凝土技术，实现了钢管劲性柱内外混凝土的一体化快速高质量浇筑；采用设有牛腿和自粘橡胶条的钢模板作为管外混凝土的支模体系，提高了模板的稳定性和密封性；采用外套箍浮浆收集技术，实现了对混凝土浮浆的快速收集再利用。
