Reinforcing method for steel structure purline simple support node connection
The invention discloses a reinforcing method for steel structure purline simple support node connection. The method is characterized in that a node reinforcing structure for reducing the mid-span moment in purline is arranged on a web plate on the inner side of a steel purline, and the node reinforcing structure consists of two angle steels and a node plate; and wide-edge flanges of the two anglesteels are superposed on the web plate on the inner side of the steel purline, two narrow-edge flanges of the two angle steels are tightly propped against an upper flange and a lower flange on the inner side of the steel purline, and the two angle steels are connected with the steel purline and the T-shaped node plate through bolts. Compared with the prior art, the method has the advantages of changing the support form of a purline rod piece, reducing the stress level of the purline structure and enhancing the bearing capacity of the purline, the problem of insufficient bearing capacity of thepurline when the load is increased on a roof is effectively solved, the structure is simple, the manufacturing cost is low, installation is convenient, the bearing capacity improving effect is good,and safety of a building steel structure is ensured.
本发明公开了一种钢结构檩条简支节点连接的加固方法，其特点是钢檩条内侧的腹板上设有降低檩条跨中弯矩的节点加固结构，所述节点加固结构为两根角钢与节点板组成；所述两角钢的宽边翼缘叠合设置在钢檩条内侧的腹板上，其两窄边翼缘与钢檩条内侧的上、下两翼缘顶紧，且由螺栓与钢檩条和“T”形节点板连接。本发明与现有技术相比具有改变檩条杆件的支座形式，降低檩条结构的应力水平，增强檩条的承载力的优点，有效解决了屋面增加荷载时出现的檩条承载力不足的情况，结构简单，制作费用低，安装方便，承载力增强效果好，确保建筑钢结构的安全。
