Large concrete-filled steel tubular column pouring construction structure and construction method
The invention discloses a large concrete-filled steel tube column pouring construction structure and a construction method, and belongs to the technical field of building construction. The large concrete-filled steel tube column pouring construction structure can achieve high-efficiency construction and comprises a steel tube, the height H from the top end of the steel pipe to a reference plane isnot lower than 40 m, a first pouring hole is formed in the side wall of the bottom of the steel pipe, a second pouring hole is formed in the side wall of the middle of the steel pipe, a concrete conveying pipe communicates with the second pouring hole, a connecting pipe section inclining downwards and forming an included angle theta with the vertically-arranged steel pipe is arranged at the position, communicating with the second pouring hole, of the concrete conveying pipe, a check valve is arranged on the connecting pipe section, and an exhaust overflow hole is formed in the top of the steel pipe. According to the large concrete-filled steel tube column pouring construction structure and the construction method, by arranging a two-stage pumping, jacking and pouring mode, layered jackingand self-compacting pouring construction is achieved, vibration operation is not needed, and the construction efficiency can be effectively improved.
本发明公开了一种大型钢管混凝土柱浇注施工结构及施工方法，属于涉及建筑施工技术领域，提供一种可实现高效率施工的大型钢管混凝土柱浇注施工结构，包括钢管，所述钢管的顶端距离基准面的高度H不低于40m，在钢管的底部的侧壁上设置有第一浇注孔，在钢管的中部的侧壁上设置有第二浇注孔，与第二浇注孔连通的设置有混凝土输送管，所述混凝土输送管在与第二浇注孔连通的部位设置有与竖向设置的钢管夹角θ的呈向下倾斜的连接管段，并且在连接管段上设置有止回阀；在钢管的顶部设置有排气溢流孔。本发明通过设置两级泵送顶升灌注的方式，实现分层顶升自密实浇注施工，可以不需进行振捣作业，可有效地提高施工效率。
