The specific meanings of the above terms in the present application can be understood in the specific circumstances for those skilled in the art.

The inventors of the present application have found through research and analysis that the existing track beam is mostly a hinged type compression bearing. As shown in Fig. 1, the upper pendulum 11 is pre-buried at the PC beam end by the anchoring steel bar 3, and is hinged with the hem 12 through the hinge shaft 13; the base plate 2 is pre-buried in the cover beam by the anchoring steel bar 3, and the frame beam is then anchored. The bolt 21 is connected to the hem 12 . In the hinged support, the contact area of the hinge shaft 13 with the upper pendulum 11 and the hem 12 is small, and the contact stress is very large, which greatly limits the overall bearing capacity of the support, and cannot meet the use requirements when encountering a large span beam. The load carrying capacity can only be increased by increasing the thickness of the swing limb 10. As a result, the volume of the support increases, and the manufacturing cost and installation cost of the support increase, which is particularly cumbersome; and when the PC beam is subjected to the torsional moment, the support is biased, that is, only one side of the swing 10 is pressed. The other side of the swing limb 10 is pulled, there will be an overhead trend. At the same time, the main body of the base plate 2 of the existing support is generally a steel casting piece. When the anchoring steel bar 3 is directly welded to the base plate 2, the base plate 2 needs to bear tensile force in addition to the shearing force, and the pair of base plates 2 The quality requirements are high; Moreover, due to the influence of the environment, the capacity of such supports is limited and cannot meet the demand for large-volume supply. In addition, in order to leave a space for rotation, a gap is required in the similar tensile structure in the prior art, and the gap can be eliminated after the gap is removed during the working process, which makes the stability of the bearing very poor. . For the above reasons, the inventors have improved the support of the track beam to obtain the technical solution of the present application.
