Variable-cross-section concrete-filled square steel tubular column connecting joint
The invention relates to a variable-cross-section concrete-filled square steel tubular column connecting joint. The connecting joint comprises an upper concrete-filled square steel tubular column (1) and a lower concrete-filled square steel tubular column (2) that are arranged in an up-down structure mode, a sealing plate (3) connected between the upper concrete-filled square steel tubular column (1) and the lower concrete-filled square steel tubular column (2), and an overhanging plate (31) which is arranged at the bottom of the pipe wall of the upper concrete-filled square steel tubular column (1), and the overhanging plate (31) is inserted into concrete of the concrete-filled square steel tubular column (2). Compared with the prior art, the connecting joint has the advantages of being suitable for rigid connection between the variable-cross-section concrete-filled square steel tubular columns, capable of forming multiple stress defense lines and the like.
本发明涉及一种变截面方钢管混凝土柱连接节点，包括呈上下结构设置的上部方钢管混凝土柱(1)、下部方钢管混凝土柱(2)，连接在上部方钢管混凝土柱(1)与下部方钢管混凝土柱(2)之间的封口板(3)，以及设置在上部方钢管混凝土柱(1)的管壁底部的外伸板(31)，所述外伸板(31)插入下部方钢管混凝土柱(2)的混凝土内。与现有技术相比，本发明具有适用于变截面方钢管混凝土柱间的刚性连接、可形成多道受力防线等优点。
