The invention relates to the technical field of engineering construction, in particular to a tile stacking and laying device for building construction. The tile stacking and laying device for the building construction comprises a flat plate trolley and a laying mechanism, the laying mechanism comprises a material receiving assembly, a flattening assembly and a leveling assembly, and a transfer mechanism and a paste feeding mechanism are further included. The transfer mechanism comprises a sliding rod, a driving assembly and an adsorption assembly, the paste feeding mechanism comprises a stirring kettle and a stirring assembly, and a push assembly is arranged at the top of the flat plate trolley. The push assembly, the material receiving assembly, the flattening assembly, the leveling assembly, the driving assembly, the adsorption assembly and the stirring assembly are all electrically connected with a control panel. According to the tile stacking and laying device for the building construction, the manual tile fixing is replaced with an automatic mode, the speed of fixing tiles is sped up, the working efficiency is improved, the labor intensity is reduced, and the fixing work of the tiles can be completed only by pushing the flat plate trolley by one person; and getting cement slurry many times in a short period of time is not required, the time of tile fixing is shortened, thelabor force is reduced, and the cost of tile fixing is reduced.
