Mixed-connected multi-section prefabricated assembled pier
The invention relates to a mixed connection multi-section prefabricated assembly pier which is used for a single column pier and comprises a pier bottom bearing platform, a pier top cover beam and a plurality of non-plastic hinge area longitudinal bar extending sections connected with the pier bottom bearing platform and the pier top cover beam, a non-plastic hinge area longitudinal bar lap joint section is arranged between every two adjacent non-plastic hinge area longitudinal bar extending sections, and a plurality of non-plastic hinge area longitudinal bar lap joint sections are arranged between every two adjacent non-plastic hinge area longitudinal bar lap joint sections. The pier bottom bearing platform is connected with the lowermost non-plastic hinge area longitudinal bar extending section through a first plastic hinge area section. The prefabricated assembled pier is used for a double-column pier and a multi-column pier and comprises a multi-column pier top cover beam and a plurality of pier bottom bearing platforms, and each pier bottom bearing platform is connected with the multi-column pier top cover beam through a first plastic hinge area section and a second plastic hinge area section in sequence. Compared with the prior art, the method has the advantages of reliable connection performance, high construction efficiency, low precision requirement, high economical efficiency and the like.
本发明涉及一种混合连接的多节段预制拼装桥墩，用于单柱墩，包括墩底承台、墩顶盖梁以及连接所述墩底承台和所述墩顶盖梁的多个非塑性铰区纵筋伸出节段，相邻两个所述非塑性铰区纵筋伸出节段之间设有非塑性铰区纵筋搭接节段，所述墩底承台与最下方的非塑性铰区纵筋伸出节段之间通过第一塑性铰区节段连接。用于双柱墩和多柱墩，该预制拼装桥墩包括多柱墩顶盖梁和多个墩底承台，每个所述墩底承台依次通过第一塑性铰区节段和第二塑性铰区节段与所述多柱墩顶盖梁连接。与现有技术相比，本发明具有连接性能可靠、施工效率高、精度要求低、经济性高等优点。
