Steel anchor beam without corbels

The invention provides a steel anchor beam without corbels. The steel anchor beam without the corbels comprises end supports (1), a middle balance beam (2) and stay cable anchoring heads (3). The end supports (1) are connected with tower walls (4) through shear studs (15) or PBL shear keys (16), and the end supports (1) are connected with a web (5) and top plates (6) of the middle balance beam (2) through high-strength bolts. The stay cable anchoring heads (3) are symmetrically arranged on a bottom plate (7) located on the inner sides of the two ends of the web (5) of the middle balance beam (2), and under-anchor #-shaped plates (10) of the stay cable anchoring heads (3) are connected with the web (5), the top plates (6) and the bottom plate (7) of the middle balance beam (2). The steel anchor beam without the corbels has the advantages that the overall height of the steel anchor beam structure is reduced; when a stay cable is tensioned, the middle balance beam slides on connecting bolt hole positions in a self-adaptive mode in the cable force direction, constraint in the horizontal direction of the middle balance beam is released, so that deformation is generated, and the middle balance beam bears the horizontal component balance part of the stay cable. According to the steel anchor beam without the corbels, it is guaranteed that the steel anchor beam bears the most horizontal component of the stay cable, the problem of height limit of the steel anchor beam is solved, meanwhile steel consumption is reduced, and therefore the application range of the steel anchor beam is widened.
