Reinforced welded steel beam support node

CHANG CHEN / SHEN SONGLIN / SONG YOUHONG / WANG HUIJIA / ZHOU SHUANG

The reinforced welded steel beam support node comprises an H-shaped steel beam and flanges, the H-shaped steel beam is formed by welding a web, an upper flange and a lower flange, the flanges are arranged below the H-shaped steel beam, a hollow steel pipe beam is arranged on the flanges, the axis of the hollow steel pipe beam is perpendicular to the axis of the H-shaped steel beam, and limiting strips are arranged on the two sides of the hollow steel pipe beam. The limiting strips are fixed to the flanges through bolts, and the hollow steel pipe beam is connected with the lower flange. Compared with the prior art, the reinforced welded steel beam support node has the beneficial effects that the reinforced welded steel beam support node is simple and reasonable in structural design, safe and reliable, node force transmission is clear, end bending moment can be released, the hollow steel pipe beam only needs to bear vertical load, part of energy can be absorbed when the beam or the column shifts or rotates, structural deformation is buffered, and the service life of the node is prolonged. The whole structure is protected, and the anti-seismic performance of the structure is improved.

本发明公开一种加强型焊接钢梁支座节点，包括H型钢梁和翼缘，H型钢梁由腹板、上翼缘和下翼缘焊接组成，翼缘设置在H型钢梁下方，翼缘上设置有空心钢管梁，空心钢管梁的轴线与H型钢梁的轴线垂直设置，空心钢管梁两侧设置有限位条，限位条通过螺栓固定在翼缘上，空心钢管梁与下翼缘连接。与现有技术相比，本发明的有益效果在于：本发明加强型焊接钢梁支座节点，结构设计简单合理，安全可靠，节点传力清晰明了，能够释放端部弯矩，空心钢管梁只需承担竖向荷载，能够在梁或柱发生位移或转动时吸收部分能量，缓冲结构变形，有利于整个结构的保护，提高结构的抗震性能。
