Background The I-shaped vertical beam and the cross beam are connected in a common assembly mode in construction of the bearing type hot-rolled metal steel beam, the excellent bending resistance and shearing resistance of the I-shaped steel are supported, a stable structural support can be provided for heavy load scenes, and the I-shaped steel beam is suitable for construction scenes with high requirements on the bearing capacity of the steel beam, such as industrial plants and large storage buildings. In the connecting structure, the end parts of the cross beams are rigidly connected with the I-shaped vertical beams through a plurality of groups of bolts, and the bolts are fastened to form an integral stress structure, so that effective load transmission and dispersion can be realized theoretically. However, in the actual use process, the direct end bolt connection mode has obvious stress short plates, and various acting forces such as vertical pressure, horizontal shearing force and the like born by the cross beam can directly and intensively act on the connection part of the cross beam and the vertical beam, so that the secondary dispersion of stress can not be realized through the structure. The steel beam parent metal of the connecting part is required to have enough bearing performance, and each group of bolts can uniformly bear load, so that the overload of the single group of bolts is avoided. If the steel beam at the connecting part has material defects, the fastening of bolts is not in place or the arrangement is unreasonable, the stress concentration at the connecting part is easy to be caused, the problems of loosening of bolts, deformation of base materials, cracking of the connecting part and the like can occur under long-term loading, and the stability and the safety of the whole steel beam structure are affected.
