The invention discloses a concentrator for an architectural experiment and a realizing method of the concentrator. The concentrator comprises a concentrator main body provided with a top column, supporting columns, a line concentration pulley set, a balance weight pulley set and a controller. A left limiting device, a right limiting device, a laser and an endpoint limiting device are mounted on the obverse side of the top column. A driving wheel and a driven wheel are mounted on the back surface of the top column. The controller is mounted on the end face of the top column. An inclined rail ismounted below the laser. According to the concentrator for the architectural experiment and the realizing method of the concentrator, the stable and firm effects are achieved in a simulation test ofthe architectural experiment, system control is accurate, friction force is small, the line storage quantity is large, the concentrator with the intelligent line concentration function can be formed absolutely, the line winding buffer function is achieved, and the concentrator is suitable for application and promotion.
