Rail supporting device of building

The utility model relates to a rail supporting device of building, and can effectively settle the requirement of flow operation to rail laying and prevents the potential safety hazard caused by rail deformation. The technical solution for settlement is characterized in that: the rail supporting device comprises a crossbeam and supporting frames; the supporting frames are symmetrically equipped to two ends of the crossbeam; the crossbeam between two supporting frames is provided with two symmetrical fixed frames; each fixed frame is provided with a corresponding transverse push rod; the push top at the front end of each push rod is provided with a clamp; and the steel rails are vertically equipped to the beam through the clamps. The rail supporting device of building has the following advantages: novel and unique structure, convenient installation and use, convenient detachment and transportation, capacity for fully satisfying the requirement of flow operation of building, capacity for being recycled, low cost
