The invention relates to a ground aerial structure capable of being leveled on flooring in a building. The structure solves the problems that workloads are large, the period is long, pollution exists and the weight of the building is increased. The structure is characterized in that a plurality of support beams are arranged on a ground foundation, and tile positioning grooves are formed in the tops of the support beams; each support beam comprises a supporting cross beam located at the bottom, and a buckle cross beam buckled to the upper portion of each supporting cross beam; a nut seat frame is arranged in each buckle cross beam, and each buckle cross beam and the corresponding supporting cross beam are connected through an adjusting screw. Supporting force is strong, the structure is sable, buckling between tiles and the buckle cross beams is more compact, and collision sound between hard objects is avoided. Detachment is facilitated, use of cement mortar is reduced, the environment is beautified, workloads are reduced, cost is reduced, operation is convenient, resources are saved, the structure can be installed without special skills, the structure can be detached and repeatedly used, all the parts are industrially produced, and economic benefits are improved.
