Combined built-in type connecting structure between prefabricated pier column and base and construction method
The invention relates to a combined built-in connection structure between a prefabricated pier column and a base and a construction method thereof, the combined built-in connection structure is provided with the prefabricated pier column and the base, a built-in groove is formed in the upper part of the base, shear nails and connecting steel bars are pre-embedded in the side walls of the built-in groove and the built-in column, and the prefabricated pier column is composed of a pier column body and the built-in column; pier column main reinforcements are distributed along the outer side wall of the pier column body and penetrate out of the bottom of the pier column body, connecting reinforcements are pre-buried in the built-in groove and the built-in column, the built-in column and the built-in groove are connected through a bedding or grouting method, post-cast strip concrete is poured on the peripheries of the built-in groove and the built-in column, and built-in connection between the prefabricated pier column and a base is achieved. The built-in depth of the prefabricated pier column is obviously reduced, and extra thickening of the base is not needed; the connecting structure is clear in axial force, shearing force and bending moment transmission mechanism and reliable in stress; the connection between the built-in groove and the built-in column is relatively strong, the integrity is good, the construction pouring is convenient, and the quality is convenient to control; meanwhile, the connecting structure is extremely high in construction speed, good in seam durability and low in cost.
一种预制墩柱与基座间组合的嵌固式连接结构及其施工方法，具有预制墩柱和基座，基座的上部设有嵌固槽，嵌固槽和嵌固柱的侧壁均预埋有剪力钉和连接钢筋，预制墩柱由墩柱本体和嵌固柱组成，墩柱主筋沿墩柱本体外侧壁分布从墩柱本体底部穿出，嵌固槽和嵌固柱的内部均预埋连接钢筋，嵌固柱和嵌固槽间进行坐浆或灌浆法连接，在嵌固槽和嵌固柱周圈浇筑后浇带混凝土，实现预制墩柱与基座间的嵌固式连接，本发明显著减小预制墩柱嵌固深度，无需额外增厚基座；连接构造传递轴力、剪力、弯矩机制明确，受力可靠；嵌固槽和嵌固柱间连接较强、整体性好，施工浇筑方便、质量便于控制；同时，连接构造施工速度极快、接缝耐久性好、成本低。
