Self-compacting steel pipe concrete column and construction method
The invention relates to a self-compacting concrete-filled steel tubular column and a construction method. The construction method comprises the steps of construction preparation, precise binding of concrete-filled steel tubular column feet, reinforcement of concrete-filled steel tubular column joints, construction of a steel tube splicing platform, auxiliary positioning of lining tubes, intelligent control of concrete pumping and jacking and intelligent temperature control of the concrete-filled steel tubular column. The construction method has the beneficial effects that concrete pumping and jacking are adopted for construction, air in the steel column, especially under the transverse partition plate, is effectively eliminated, and the concrete compactness is improved; a lining pipe and a pre-embedded limiting plate are used for assisting in positioning and positioning components, a jack is used for adjusting the perpendicularity and the elevation, and it is ensured that the centroid position and the perpendicularity of the steel pipe meet the design and specification requirements; the cold water conveying pipe and the PVC heat preservation layer are arranged outside the concrete pumping pipe, concrete temperature changes are sensitively sensed through the temperature sensor, cooling and temperature control are conducted in time, the concrete mold entering temperature is effectively controlled, concrete cracks are reduced, and the concrete pouring quality is improved.
本发明涉及一种自密实钢管混凝土柱及施工方法，包括步骤：施工准备、钢管混凝土柱脚精确绑扎、钢管混凝土柱节点补强、钢管拼接平台施工、内衬管辅助定位、混凝土泵送顶升智能控制和钢管混凝土柱智能控温。本发明的有益效果是：采用泵送顶升混凝土施工，有效地排除了钢柱内尤其是横隔板下的空气，混凝土密实度得到了提高；利用内衬管和预埋限位板辅助定位、定位构件，利用千斤顶调整垂直度和标高，确保钢管形心位置及垂直度满足设计和规范要求；在混凝土泵送管外设置冷水输送管和PVC保温层，通过温度传感器敏锐感知混凝土温度变化，及时降温控温，有效控制混凝土入模温度，减少混凝土裂缝的产生，提高混凝土浇筑质量。
