Construction method of newly-added column foundation of column-cap-free beam column joint of basement roof
The invention discloses a construction method of a newly-added column foundation of a column-cap-free beam column joint of a basement roof. When a steel structure column is newly added to the column-cap-free beam column joint of the basement roof, an expanded section concrete structure is added to the top section of an expanded column, a foundation screw is pre-buried in the expanded section concrete structure to serve as a foundation embedded part of the newly-added steel structure column, shear pin ribs are implanted into an original structure in an E shape to serve as main stress steel bars of the expanded section concrete structure and original structure concrete, ring ribs of the expanded section concrete structure are implanted into the upper horizontal plane, the middle horizontal plane and the lower horizontal plane of an annular pouring space in an open hoop mode, and the integrity of the expanded section concrete structure is improved. The construction method solves the problem that in existing foundation construction of the newly-added steel structure column, due to improper component dismantling construction, the original structure is prone to being damaged or the requirement for bearing of upper newly-added steel structure modeling components cannot be met after construction is completed.
本发明公开了一种地下室顶板的无柱帽梁柱节点的新增柱基础的施工方法，在对地下室顶板的无柱帽梁柱节点新增钢结构柱时，采用扩大柱顶截面增加扩大截面混凝土结构，并在扩大截面混凝土结构中预埋地脚螺杆作为新增钢结构柱的基础埋件，在原结构上以“E”字型植入剪力销筋，作为扩大截面混凝土结构与原结构混凝土的主要受力钢筋，并在环形浇筑空间的“上、中、下”三个水平面上以开口箍形式植入扩大截面混凝土结构的环筋，增加扩大截面混凝土结构整体性。本发明解决了现有的新增钢结构柱的基础施工，因构件拆除施工不当，容易导致原结构损坏或完工后不能满足上部新增钢结构造型构件承重的要求的问题。
