Folding beam-column connecting joint of precast concrete structure and construction method
The invention discloses a folding beam-column connecting joint of a precast concrete structure and a construction method. Anchoring steel bars and semi-cylindrical connecting blocks are welded to the two side faces of a beam end steel plate and the two side faces of a column end steel plate, concrete, a beam body and a column body are integrally poured, the beam end steel plate is arranged on the surface of the beam body, the column end steel plate is arranged on the surface of the column body, an inclined rod with a hole and a horizontal rod with a hole are arranged between every two semi-cylindrical connecting blocks, short steel bars are inserted into the parallel holes for connection, and then the beam-column connecting position is poured through self-compacting concrete. According to the folding beam-column connecting joint of the precast concrete structure and the construction method, the truss stress principle is utilized, the upper horizontal rod and the lower horizontal rod bear tension and pressure respectively, the bending moment of the joint is transmitted, an inclined web member bears tension or pressure, the shearing force of the joint area is transmitted, the stress mode of the bending moment and the shearing force is converted into the tension and pressure of the rod pieces, and the material utilization rate is increased.
本发明公开了一种预制混凝土结构折叠式梁柱连接节点及施工方法，锚固钢筋和半圆柱连接块焊接在梁端钢板和柱端钢板两侧面，用混凝土与梁体和柱体整体浇筑，梁端钢板在梁体表面，柱端钢板在柱体表面，每两个半圆柱连接块之间有一根带孔斜杆和一根带孔水平杆，在平行孔内插入短钢棒连接，然后用自密实混凝土浇筑梁柱连接处。本发明利用桁架受力原理，上下水平杆分别受拉力和压力，传递节点部位弯矩，斜腹杆受拉力或压力，传递节点区剪力，把弯矩和剪力的受力模式转换为杆件的拉力和压力，提高了材料利用率。
