The invention relates to a wall surface leveling system and leveling method, and problems that for the existing wall surface lightgage steel joist leveling mode, the mounting structure is complex, the space occupied by the leveling basement layer is relatively large, and the leveling mode is not suitable for being applied to a small space are solved. A plurality of vertical joists are arranged between a heaven joist and an earth joist in an embedded manner, the upper and lower ends of each vertical joist are respectively clamped into U-shaped grooves of the heaven joist and the earth joist, each vertical joist has a U-shaped cross section, the opening side of each vertical joist faces the wall surface, a plurality of adjusting blocks are arranged in a U-shaped groove of each vertical joist from top to bottom, the central part of each adjusting block is provided with a screwed hole, an adjusting stud is arranged in each screwed hole in an adjustable manner, the inner end of each adjusting stud abuts against the wall surface, the center of each adjusting stud is provided with a bolt hole, and a bolt fixing the adjusting stud on the wall surface is arranged in a manner of traversing the corresponding bolt hole. The vertical joists are supported by side surfaces of the adjusting blocks, and therefore the wall surface can be leveled quickly, the adjusting mode is simple and convenient, the space occupied by the leveling process is small, and the indoor space utilization rate is increased.

The invention provides a construction method of a long steel bar stool cast-in-situ floor, and belongs to the technical field of building construction. The method includes the steps of selecting steel bars, machining and manufacturing long steel bar stools, installing a formwork and beam slab steel bars, installing the steel bar stools, binding negative steel bars, casting floor concrete, carrying out overflow-surface leveling on the floor concrete, shearing off steel wires to take out the steel bar stools, repairing the concrete surface, cleaning the steel bar stools and the like. According to the method, the strength and rigidity of the steel bar stools are utilized for controlling deformation and sinking, caused by construction external force, of the negative steel bars, and thus the thickness deviation of negative steel bar protection layers of the floor is controlled; meanwhile, the height of the steel bar stools is utilized for controlling the thickness of the floor and the levelness of the floor concrete surface; the steel bar stools can be recycled, and construction is easier and more convenient.
