[0013] like Figure 1-3 As shown, a steel structure support beam with earthquake-resistant function includes a support beam 1, and a plurality of earthquake-resistant supports are installed at the bottom of the support beam 1 along its length direction. Each earthquake-resistant support includes an upper mounting plate 2 and a lower mounting plate 3. The center positions of the bottom of the upper mounting plate 2 and the top of the lower mounting plate 3 are connected with a sleeve 4. A connecting plate 6 is provided at the bottom of the upper mounting plate 2 and located inside the sleeve 4. A connecting plate 6 is provided at the top of the lower mounting plate 3 and located inside the sleeve 4. Several first earthquake-resistant structures are distributed on the outer circumference of the connecting plate 6 and the inner circumference of the sleeve 4. The first earthquake-resistant structure includes a first telescopic rod 8, a first The two ends of the telescopic rod 8 are fixedly connected with circular plates 9, and a spring 10 is provided on the outside of the first telescopic rod 8. The two ends of the spring 10 are fixedly connected to the circular plates 9 adjacent to it, one of the circular plates 9 is hinged to the inner side surface of the sleeve 4, and the other circular plate 9 is hinged to the outer periphery of the connecting plate 6. A second seismic-resistant structure is provided between the upper and lower connecting plates 6; specifically, the seismic-resistant bearing is installed at the bottom of the support beam 1, which will generate destructive force when an earthquake occurs, driving the first telescopic rod 8 to move, and the spring 10 also moves with it, thereby consuming earthquake energy and reducing damage to the support beam 1.
