The present invention relates to a method for forming patterns on a concrete floor in order to form various patterns on a surface of a concrete floor in a building. Conventionally, patterns are formed by curing and polishing a placed concrete floor and then making a coloring composition permeate a desired portion on the surface of the floor, so problems that performing the work is difficult, construction costs increase, and the patterns are decolored so the lifespan is expired due to water cleaning, scratches and repolishing as time goes by, has been pointed out. The present invention comprises the steps of: inserting colored stone, selected from colored natural stone, jade, artificial stone, glass, crystal, nacre, etc., into the floor using design lines before the placed concrete floor is hardened when concrete is placed to construct the floor; performing a flattening work; performing enough hardening work; and performing a polishing process to grind the colored stone for exposing unique colors of the colored stone via cross sections to form clean and natural multi-colored patterns while the colors are matched with one another, thereby simplifying work processes, reducing construction costs, and semi-permanently showing the unique, natural and clean colors of the colored stone. |
