Pile structure circular truncated cone type connecting structure penetrating through structural bottom plate and construction method thereof
The invention belongs to the field of building structures, and discloses a pile structure circular truncated cone type connecting structure penetrating through a structural bottom plate and a construction method thereof. According to the technical scheme, a pile structure is divided into a lower pile section, an upper column section and a connecting part between the lower pile section and the upper column section by a newly-built basement structural bottom plate; the connecting part is a circular truncated cone type connecting section; the circular truncated cone type connecting section is a variable-diameter section with the small upper portion and the large lower portion; the top section of the circular truncated cone type connecting section is smaller than the section of the pile section; the newly-built basement structural bottom plate and the circular truncated cone type connecting section are poured into a whole, a steel reinforcement cage of the pile structure is of a split type, and longitudinal main ribs of the steel reinforcement cage are divided into column section main ribs and pile section main ribs; the column section main ribs are anchored into the pile section and welded to the pile section main ribs; the pile section main ribs are upwards anchored into the basement structural bottom plate; and the steel reinforcement cage is in the shape with the small upper portion and the large lower portion in the circular truncated cone type connecting section. The problem that an existing connecting joint of the pile structure and the structural bottom plate is low in reliability is solved.
本发明属于建筑结构领域的穿越结构底板的桩柱结构圆台式连接构造及其施工方法。技术方案为：桩柱结构被新建地下室结构底板分为下部的桩段、上部的柱段和之间的连接部分；连接部分为圆台式连接段；圆台式连接段为上小下大的变直径截面；圆台式连接段的顶截面小于桩段的截面；新建地下室结构底板与圆台式连接段浇筑成一整体，桩柱结构的钢筋笼采用分体式，钢筋笼的纵向主筋分为柱段主筋和桩段主筋；柱段主筋锚入桩段，与桩段主筋焊接；桩段主筋向上锚入地下室结构底板中；钢筋笼在圆台式连接段内的形状为上小下大。解决了现有桩柱结构与结构底板连接节点可靠度较低的问题。
