[0002] Many old office buildings are mainly built with masonry structures, and the renovation of the buildings is mainly focused on the change of spatial functions. When dismantling the original non-load-bearing partition walls, it will be found that there is no ring beam above the partition walls. If the walls are dismantled rashly, it will cause serious construction safety accidents. In response to the above problems, it is necessary to add lintels at the opening positions, or add support beams at the demolished original walls. However, the quality of concrete beam casting and vibration is poor, the construction is complex, and the construction period is long. This phenomenon has become a problem that needs to be solved urgently by personnel in this field. Therefore, the steel lintel reinforcement structure of the existing brick masonry building is designed, and the masonry structure is replaced with steel structural components, which can shorten the construction period, is more convenient for construction, and has low labor costs.
