Round steel column and square steel beam assembly type connecting structure

ZHUO YUE / LUO FENG / LYU ZHONGFEI

The invention discloses a round steel column and square steel beam assembly type connecting structure which comprises a first steel column and a second steel column. The section size of the first steel column is larger than that of the second steel column, a column top edge sealing plate is arranged at the top of the first steel column, and a stiffening plate is arranged in the first steel column; and the bottom of the first steel column is fixedly connected with a first circular connecting plate, the top of the second steel column is fixedly connected with a second circular connecting plate, the first circular connecting plate and the second circular connecting plate are fixedly connected through bolts, and a square steel beam is arranged on the periphery of the first steel column. By means of the round steel column and square steel beam assembly type connecting structure, due to the structural design, reliable connection between the second steel column and the square steel beam is effectively achieved when the diameter of the second steel column is limited to a certain degree, the column top edge sealing plate can be suitable for various steel structures, and the conditions that when the diameter of the second steel column is limited, the width of the square steel beam is close to the diameter of the second steel column, consequently, the square steel beam and the second steel column cannot be reliably connected, and existing related steel structure graph set nodes are not applicable are avoided.

本发明公开了一种圆钢柱与方钢梁装配式连接结构，包括第一钢柱和第二钢柱，第一钢柱的截面尺寸大于第二钢柱的截面尺寸，第一钢柱的顶部设置有柱顶封边板，第一钢柱的内部设置有加劲板，第一钢柱的底部固定连接有第一圆形连接板，第二钢柱的顶部固定连接有第二圆形连接板，第一圆形连接板和第二圆形连接板之间通过螺栓固定连接，第一钢柱的周圈上设置有方钢梁。本发明由于上述结构设计，有效实现第二钢柱的直径在受到一定限制要求下与方钢梁的可靠连接，柱顶封边板可适用于多种钢结构，解决了第二钢柱的直径在受到限制下，方钢梁宽度与第二钢柱直径相近，导致方钢梁与第二钢柱无法可靠连接的矛盾以及现有相关钢结构图集节点不适用的情况。
