Steel frame capable of supporting without bearing vertical load
The invention provides a steel frame capable of supporting without bearing a vertical load. The frame comprises two steel columns, a steel beam, a supporting mechanism and supporting brackets, wherein the two ends of the steel beam are in rigid connection with the upper ends of the two steel columns in a one-to-one correspondence mode, two steel beam brackets are arranged at the bottom of the steel beam at intervals, the supporting mechanism is arranged between the two steel columns and connected with the two steel columns, the supporting brackets are arranged between the two steel beam brackets, gaps are formed between the supporting brackets and the steel beam, side plates of the supporting brackets are connected with the steel beam brackets through connecting pieces, and the lower ends of the supporting brackets are connected with the supporting mechanism. By improving the connecting mode of the supporting mechanism and the steel beam, a vertical sliding connecting structure is provided, and the purposes that under the action of the vertical load, the supporting mechanism is not stressed, and under the action of a horizontal load, the supporting mechanism and the steel frame work cooperatively are achieved; and the rigidity and the strength of a supporting structure are completely used for resisting the horizontal load effect, so that the actual lateral resistance of the supporting structure is effectively improved.
本发明提供一种支撑不承受竖向荷载的钢框架，包括两根钢柱、钢梁、支撑机构和支撑牛腿，钢梁的两端与两根钢柱的上端一一对应地刚接连接，钢梁的底部间隔设置有两个钢梁牛腿；支撑机构设置于两根钢柱之间，支撑机构分别与两根钢柱连接；支撑牛腿设置于两个钢梁牛腿之间，且与钢梁之间设置有间隙，支撑牛腿的侧板通过连接件与钢梁牛腿连接，支撑牛腿的下端与支撑机构连接。通过改进支撑机构与钢梁的连接方式，提出一种竖向滑动连接结构，实现在竖向荷载作用下，支撑机构不受力，在水平荷载作用下，支撑机构与钢框架协同工作的目的。使得支撑结构的刚度和强度完全用于抵抗水平荷载作用，从而有效提高了支撑结构的实际抗侧能力。
