Hoop type connecting structure for connecting three-way steel truss with concrete column

HU XIAODONG

The invention discloses a hoop type connecting structure for connecting a three-way steel truss with a concrete column. The hoop type connecting structure comprises the concrete column, a truss chord member, a truss web member and a hoop type joint; the concrete column is connected with the hoop type joint; the truss chord member and the truss web member are connected to the side end of the hoop type joint; the hoop type joint comprises column-wrapped steel, a supporting column, a column bottom plate, a foundation anchor bolt and an outer ring plate; the outer ring plate is arranged on the outer wall of the column-wrapped steel; a truss chord member connector is arranged on the outer ring plate; a truss web member connector is arranged between the outer ring plate and the column-wrapped steel; the column-wrapped steel is of a box structure and comprises a stud, a stiffening plate and a box; the stud and the stiffening plate are both arranged on the box; the box wraps the periphery of the concrete column; the side end of the box is connected with the truss chord member through the truss chord member connector; and the side end of the box is connected with the truss web member through the truss web member connector. The hoop type connecting structure has the advantages that a steel beam and the concrete column are effectively connected, self-installation is convenient, and the construction difficulty is lowered.

本发明公开了一种三向钢桁架连接混凝土柱抱箍式连接结构。它包括混凝土柱、桁架弦杆、桁架腹杆和抱箍式节点；混凝土柱与抱箍式节点连接，桁架弦杆、桁架腹杆分别连接在抱箍式节点侧端；抱箍式节点包括柱包钢、支撑柱、柱底板、地脚锚栓和外环板；外环板设置在柱包钢外壁上；桁架弦杆接头设置在外环板上；桁架腹杆接头设置在外环板与柱包钢之间；柱包钢为箱体结构；柱包钢包括栓钉、加劲板和箱体；栓钉和加劲板均设置在箱体上；箱体包裹在混凝土柱外周；箱体侧端通过桁架弦杆接头与桁架弦杆连接；箱体侧端通过桁架腹杆接头与桁架腹杆连接。本发明具有实现钢梁与混凝土柱的有效连接，并方便自身安装，降低施工难度的优点。
