The invention discloses a joint connecting device for a reinforced concrete column and a steel beam and belongs to the technical field of buildings and structural engineering. The joint connecting device can be prefabricated first in a plant, and is then transported to a construction site for construction. The invention belongs to an assembled structure and has the advantages of being high in construction efficiency, environment-friendly, energy-saving and the like. In an aseismic design, the energy-dissipating capacity is a key point which is concerned. In many energy-dissipating modes, boltsare a relatively ideal energy-dissipating mode, and the energy-dissipating ability can be improved as the bolts slide. The joint connecting device just uses the bolts to achieve joint connection between the reinforced concrete column and the steel beam, so that the energy-dissipating capacity is relatively high. A first connecting part of the joint connecting structure is composed of a first beamchannel and a second beam channel. The double beam channels can improve the force transfer by joint connection. In case of an earthquake, the double beam channels are to be damaged first, so that thecolumn and the beam are retained to the maximum extent, and therefore, the beam-column structure can be restored quickly after the earthquake.

本发明公开了一种钢筋混凝土柱与钢梁的节点连接装置，属于建筑技术领域以及结构工程技术领域。此节点连接装置可先在工厂进行预制，再运送至施工现场进行施工，属于装配式结构，具有施工效率高、环保、节能等优点。在抗震设计中，耗能能力也是受到关注的一个重点，在众多耗能方式中，螺栓是比较理想的耗能方式，可以通过螺栓之间相互滑移来增加其耗能能力，而此节点连接装置正好是使用螺栓来实现钢筋混凝土柱与钢梁之间的节点连接，耗能能力较强。此节点连接装置的第一连接件由第一槽钢和第二槽钢组成，双槽钢可提高节点连接传力，一但遇到地震，双槽钢会率先被破坏，使得柱和梁被最大程度的保留，进而使得梁柱结构在震后可快速恢复。
