Fabricated ductile energy dissipation joint for reinforced concrete frame and construction method of fabricated ductile energy dissipation joint
The invention discloses an assembly type ductile energy dissipation joint for a reinforced concrete frame and a construction method thereof. The construction method comprises the steps that firstly, an upper prefabricated column, a lower prefabricated column and a prefabricated beam are manufactured; secondly, the lower prefabricated column is installed in place; thirdly, the upper prefabricated column is hoisted, and the upper connecting cylinder is aligned to the lower connecting cylinder; fourthly, the joint of the upper connecting cylinder and the lower connecting cylinder is connected through butt-joint slope welding; 5, welding the adapter, the upper connecting cylinder and the lower connecting cylinder into a whole; sixthly, the replaceable energy dissipation connecting pieces are hoisted, and the replaceable energy dissipation connecting pieces are connected with the adapting pieces through first high-strength bolts; and seventhly, the precast beam is hoisted, the joint connecting pieces and the replaceable energy dissipation connecting pieces are connected through second high-strength bolts, and construction is completed. The technical problems that a traditional reinforced concrete frame joint is prone to plastic damage and residual deformation, the problem of structural damage repair after an earthquake is not considered, and the advantages of a prefabricated structure are difficult to play to the maximum extent are solved.
一种用于钢筋砼框架的装配式延性消能节点及其施工方法，包括步骤一：制作上预制柱、下预制柱和预制梁；步骤二：将下预制柱安装就位；步骤三：吊装上预制柱，将上连接筒对准下连接筒；步骤四：在上连接筒与下连接筒接缝处采用对接坡焊连接；步骤五：将转接件与上连接筒和下连接筒焊接为一个整体；步骤六：吊装可更换消能连接件，将可更换消能连接件与转接件采用第一高强螺栓连接；步骤七：吊装预制梁，将节点连接件与可更换消能连接件采用第二高强螺栓连接，至此施工完毕。本发明解决了传统的钢筋砼框架节点易产生塑性损伤破坏与残余变形，未考虑地震后结构损伤修复问题以及难以最大限度地发挥预制结构的优势的技术问题。
