[0006] Preferably, four frame steel bars are pre-installed in the beam body, and the four frame steel bars are in a cubic shape. Every three different frame steel bars form a frame steel bar group, forming a total of four frame steel bar groups. Each group of frame steel bars is respectively tied with three limiting steel bars, and the ends of the three limiting steel bars are tied together and fixedly connected with the threaded hole plate.
[0007] Preferably, a hemispherical limit block is provided at the contact portion between the adjusting bolt and the threaded hole plate.
