Novel energy-saving self-resetting UHPC (Ultra High Performance Concrete)-concrete combined frame node
The invention provides a novel energy-saving self-resetting UHPC (Ultra High Performance Concrete)-concrete combined frame node, which belongs to the technical field of building construction, and is specifically characterized in that a prefabricated UHPC-concrete combined beam and a prefabricated UHPC-concrete combined column are assembled together through an energy consumption connecting piece and an unbonded prestressed steel strand, and the frame node is a dry connection node. The assembled novel energy-saving self-resetting UHPC-concrete combined frame joint comprises a connecting joint and other areas except the connecting joint, UHPC is poured into the connecting joint, and common concrete is still adopted in other areas. The two small angle steel bars are arranged at the end, connected with the UHPC-concrete combination column, of the UHPC-concrete combination beam, so that possible local damage to the corners in the transportation and installation process is prevented. On the basis of ensuring that the node has good anti-seismic performance, damage control capability and self-resetting capability, the low-carbon energy-saving effect of the node is further improved.
本发明提供一种新型节能自复位UHPC‑混凝土组合框架节点，属于建筑施工技术领域，框架节点具体为：通过耗能连接件及无粘结预应力钢绞线将预制UHPC‑混凝土组合梁和预制UHPC‑混凝土组合柱装配在一起，是一种干连接节点。装配后的新型节能自复位UHPC‑混凝土组合框架节点包括连接节点和除连接节点以外的其他区域，连接节点浇筑UHPC，其他区域仍采用普通混凝土。UHPC‑混凝土组合梁在与UHPC‑混凝土组合柱相连的端部布置2个小角钢条，防止运输安装过程中可能出现的角部局部破损。本发明在确保节点具有良好的抗震性能、损伤控制能力及自复位能力的基础上，进一步提高节点低碳节能效果。
