Reinforced key groove connection joint beam-column structure
The invention discloses a reinforced key groove connection joint beam-column structure, and belongs to the technical field of structural engineering. The structure comprises frame beams, frame columns, tie bars, additional tie bars and a separation net. The frame beams comprise pre-poured precast beams, the frame columns comprise pre-poured precast columns, key grooves are formed in the connectingpositions of the precast beams of the frame beams and the frame columns, and the key groove sare trapezoidal; the tie bars and the additional tie bars are arranged along the key grooves and the precast beams, concrete is poured into the key grooves, and the precast beams, the frame columns and the key grooves are connected into a whole; the surfaces of the key grooves are rough, so that the contact area and the bonding performance of the post-poured concrete and the precast concrete are further increased, and the stability of a joint is guaranteed; and considering the stability and economic cost of the joint, a precast part is made of common concrete, ECC concrete with high ductility, high ultimate compressive strain and other properties is poured into the key grooves, and the separationnet is laid along the key grooves, so that the common concrete and the ECC concrete are separated, and the stability of the key groove joint is guaranteed.
本发明的一种加强型键槽连接节点梁柱结构，属于结构工程技术领域。包括框架梁、框架柱、拉结钢筋、附加拉筋和分隔网。框架梁包括预浇筑的预制梁，框架柱均包括预浇筑的预制柱，框架梁的预制梁和框架柱连接处形成键槽，该键槽呈梯形；沿键槽和预制梁设置拉结钢筋和附加拉筋，并在键槽中浇筑混凝土，将预制梁、框架柱和键槽连接成整体；且键槽表面粗糙，进一步增加了后浇混凝土和预制混凝土的接触面积和粘结性能，保证节点的稳定性；考虑到节点的稳定性与经济成本，本发明中预制部分采用普通混凝土，在键槽中浇筑具有高延性、高极限压应变等性能的ECC混凝土，并将分隔网沿键槽铺设，使普通混凝土和ECC混凝土分隔开，保证键槽节点的稳固性。
