进一步的，所述第一连接座采用吊耳结构，所述第二连接座采用相互连接的吊耳结构和连接板，所述吊耳结构与连接板之间呈一定夹角。
进一步的，所述斜拉的槽钢采用C型槽钢，所述水平的槽钢采用C型槽钢或双C型槽钢。
进一步的，所述连接片与斜拉的槽钢通过槽钢锁扣及螺栓固定连接，所述槽钢锁扣与斜拉的槽钢接触处设有防滑锯齿。
本发明还公开了一种高强度抗震支吊架，包括上述的一种高抗拉强度抗震连接件，还包括竖直的槽钢，所述竖直的槽钢的上部通过膨胀螺栓和加长螺母与建筑结构固定连接，所述竖直的槽钢的下部通过吊杆螺栓与水平的槽钢固定连接，所述水平的槽钢的一端通过连接片、第二连接座与斜拉的槽钢的一端固定连接，所述斜拉的槽钢的另一端通过连接片、第一连接座与建筑结构固定连接。
进一步的，所述竖直的槽钢和斜拉的槽钢的数量均至少两根。
有益效果：本发明的抗震连接件通过将原有斜拉槽钢的单螺栓固定改为环抱式卡接固定，无需更改原有槽钢结构，从而提高了整体抗震支吊架的抗拉强度，保证了整体结构的稳定性。
