The utility model relates to the field of buildings, in particular to building piping mounting equipment, which comprises a connecting unit, a first connecting unit, a second connecting unit, a connecting unit and a connecting unit, the first connecting hole is connected with the piping of the first construction stage, and the second connecting hole is connected with the piping of the second construction stage; and the sealing unit is arranged at the position of the second connecting hole and used for sealing the second connecting hole in the first construction stage. According to the utilitymodel, the technical current situation that the traditional vertical piping is reserved on the outer surface of the floor is changed, the piping hot bending work flow is omitted, the construction is convenient, and the problem that the vertical piping cannot be well fixed is solved; the problem that the length of the vertical section piping is considered during reserved pre-burying is solved, thetrouble that post-processing is not easy due to the fact that the length of the piping is not easy to control is avoided, and the problem that impurities such as concrete fall into the vertical pipingis effectively solved. The problem that the vertical piping is easy to damage and break is solved, and the cost is saved.
