Connecting joint of PVC-FRP pipe reinforced concrete composite column and steel reinforced concrete beam
The invention discloses a connection node of a PVC-FRP pipe reinforced concrete composite column and a steel reinforced concrete beam, the connection node comprises a PVC-FRP pipe, an inner framework, a semi-arc steel plate, a node area steel beam and profile steel, the inner framework comprises a plurality of anchoring rods, and first through holes used for penetrating longitudinal bars in the pipe are formed in the anchoring rods; a plurality of second through holes allowing stirrups in the pipe to penetrate through are formed in the side wall of the PVC-FRP pipe, the first through holes are communicated with the second through holes, and concrete is poured in the PVC-FRP pipe; the node force transmission path is clear and reliable, the node area is provided with the semi-arc steel plates, the prestressed high-strength bolts and the node area steel beams to enable beam columns to form a whole, and bending moment and shearing force transmitted by the steel reinforced concrete beams are directly transmitted to the core area; the restraining effect on concrete in the PVC-FRP pipe in the joint area can be enhanced through the semi-arc steel plates connected through the prestress high-strength bolts, the steel beam web in the joint area can play a shearing resisting role, the bearing capacity and ductility of the joint are improved, and the purpose of strengthening the joint can be achieved.
本发明公开了一种PVC‑FRP管钢筋混凝土叠合柱与型钢混凝土梁的连接节点，包括PVC‑FRP管、内骨架、半圆弧钢板、节点区钢梁、型钢，所述内骨架包括多个锚定杆，所述锚定杆内部开设有用于穿设管内纵筋的第一通孔，侧壁开设有多个用于管内箍筋穿过的第二通孔，所述第一通孔和所述第二通孔连通，所述PVC‑FRP管内用于浇筑混凝土；本发明节点传力路径明确可靠，节点区通过设置半圆弧钢板、预应力预应力高强螺栓和节点区钢梁使梁柱形成整体，并将型钢混凝土梁传来的弯矩和剪力直接传递到核心区，通过预应力预应力高强螺栓连接的半圆弧钢板能够增强对节点区PVC‑FRP管内混凝土的约束作用，节点区钢梁腹板能够发挥抗剪作用，提高节点的承载力和延性，可达到强节点的目的。
