Node connecting piece and modular steel column assembly

TENG WENGANG / GAO JIAN / GAO WEI

The invention discloses a joint connecting piece and a modular steel column assembly. The joint connecting piece is used for joint connection of the modular steel column assembly. The modularized steel column assembly comprises an upper steel column, a steel column foot plate arranged at the bottom of the upper steel column, a lower steel column and a top supporting plate arranged at the top of the lower steel column. The node connecting piece comprises a first node plate and a second node plate, wherein the first node plate is connected to the upper steel column or the lower steel column through a detachable connecting piece; the second gusset plate is arranged on the first gusset plate, and a groove is formed in the second gusset plate so as to clamp the steel column foot plate and the top support plate. The first gusset plate is connected to the upper steel column or the lower steel column, and then the second gusset plate clamps the steel column foot plate of the upper steel column and the top support plate of the lower steel column, so that the joint can meet the mechanical property requirements of bending resistance, tensile resistance and shearing resistance, the force transmission path of the joint area is clear, the force transmission is reliable, and the stress of the column foot is stable; and the integrity requirement of the modular steel column structure is met while the node rigidity is achieved.

本申请公开了一种节点连接件和模块化钢柱组件，节点连接件用于模块化钢柱组件的节点连接；模块化钢柱组件包括上部钢柱、设置于上部钢柱底部的钢柱脚板、下部钢柱以及设置于下部钢柱顶部的顶部支撑板；节点连接件包括：第一节点板，通过可拆卸连接件连接在上部钢柱或下部钢柱；第二节点板，设置于第一节点板，第二节点板设有凹槽以夹持钢柱脚板和顶部支座板。通过第一节点板连接在上部钢柱或下部钢柱上，进而通过第二节点板夹持上部钢柱的钢柱脚板和下部钢柱的顶部支座板，使节点可以达到抗弯、抗拉以及抗剪的力学性能要求，节点域的传力路径清晰，传力可靠，柱脚受力稳定，在实现节点刚度的同时满足模块化钢柱结构的整体性要求。
