Reverse construction method reinforced concrete structure column connecting structure and construction method thereof
The invention relates to a reverse construction method reinforced concrete structure column connecting structure and a construction method thereof, the reverse construction method reinforced concrete structure column connecting structure comprises a pre-construction structure, a post-construction structure and a secondary pouring structure which are constructed in a soil layer, and the pre-construction structure comprises a concrete cushion layer, an underground structure top plate, a pre-stage underground structure column cap, a pre-stage underground structure upper section column, a frustum-shaped cavity structure and a grouting steel pipe; the bottom of the grouting steel pipe is communicated with the frustum-shaped cavity structure to form a secondary grouting channel; the post-construction structure comprises an underground structure column bearing platform, a temporary steel pipe support, a later-stage underground structure lower section column and a prismatic table-shaped structure, and the secondary pouring structure is a sealing structure formed in a secondary grouting seam formed by the construction seam and formed by grouting from the grouting steel pipe to the secondary grouting seam. According to the invention, an over-pouring method and a grouting method are combined, the construction quality in the construction joint is ensured through the secondary pouring structure, the wedged connection between the two column structures is realized through the design of the prismatic table-shaped cavity, the shear resistance of the connecting part is increased, and the secondary pouring structure further reinforces the construction joint.
一种逆作法钢筋混凝土结构柱连接结构及其施工方法，包括在土层内施工的先施工结构、后施工结构和二次浇注结构，先施工结构包括混凝土垫层、地下结构顶板、先期地下结构柱帽、先期地下结构上段柱、棱台形空腔结构和注浆钢管；注浆钢管的底部连通棱台形空腔结构形成二次注浆通道；后施工结构包括地下结构柱承台、临时钢管支撑、后期地下结构下段柱和棱台形结构，二次浇注结构为在施工缝形成的二次注浆缝内，自注浆钢管向该二次注浆缝内注浆形成的密封结构。本发明结合超灌法和注浆法，通过二次浇筑结构保证了施工缝内的施工质量，通过棱台形空腔的设计，实现两次柱结构之间的契合连接，增大连接部分的抗剪作用，二次浇筑结构对施工缝进一步加固。
