Fabricated prestressed concrete composite beam column frame
The invention discloses an assembly type prestressed concrete composite beam column frame which comprises a prefabricated prestressed concrete beam, a concrete column, second-stage prestressed tendons and a post-pouring concrete composite layer. The prefabricated prestressed concrete beam comprises embedded first-stage prestressed tendons, embedded corrugated pipes, bottom longitudinal tendons and stirrups, the embedded first-stage prestressed tendons and the bottom longitudinal tendons are arranged at the bottom of the prefabricated prestressed concrete beam, the embedded corrugated pipes extend out of the surface of the prefabricated prestressed concrete beam, and the stirrups are perpendicular to the bottom longitudinal tendons; the concrete column comprises a bracket, a reinforcing steel bar connecting part and a column body, the side edge of the column body is provided with the bracket used for placing the prefabricated prestressed concrete beam, the reinforcing steel bar connecting part is arranged at the end, close to the bracket, of the column body, an exposed corrugated pipe penetrates through the reinforcing steel bar connecting part, and the exposed corrugated pipe is connected with the embedded corrugated pipe. The load is balanced by tensioning the prestressed tendons in stages, part of the prestressed tendons penetrate through the node area by exposing the corrugated pipe, and the hogging moment resistance of the beam end is improved on the premise of controlling the construction difficulty.
本发明公开了一种装配式预应力混凝土叠合梁柱框架，包括预制预应力混凝土梁、混凝土柱、第二阶段预应力筋和后浇混凝土叠合层；预制预应力混凝土梁包括内埋第一阶段预应力筋、内埋波纹管、底部纵筋和箍筋，预制预应力混凝土梁底部设内埋第一阶段预应力筋、底部纵筋，内埋波纹管伸出预制预应力混凝土梁表面，箍筋垂直于底部纵筋；混凝土柱包括牛腿、钢筋连接部和柱体，柱体的侧边设用于搁置预制预应力混凝土梁的牛腿，柱体靠近牛腿的一端设钢筋连接部，钢筋连接部上贯穿有外露波纹管，外露波纹管与内埋波纹管相连。本发明通过分阶段张拉预应力筋来平衡荷载，通过外露波纹管使部分预应力筋穿过节点区，在控制施工难度的前提下提高梁端抗负弯矩能力。
