MATTRESS FOR SOIL PLATE OR STONE PLATE AND INSTALLATION METHOD THEREOF

PURPOSE: A mattress for a soil plate or a stone plate and an installing method thereof are provided to reduce the cost of production by not using leather for decoration of the mattress and to simplify manufacturing process, thereby reducing labor cost. CONSTITUTION: A mattress for a soil plate or a stone plate comprises an upper plate (10), a side plate (20), a lower plate (30), supports (40), and a cover plate (50). The supports are arranged inside a space formed by the upper plate, the side plate, and the lower plate. The supports are arranged to be combined with combination holes on the side plate. The supports have supplementary supports on both ends and can be combined by fixing a nut with a bolt protruded into the combination hole after inserting the bolt into the combination hole from the supplementary support. The upper plate, the lower plate, the side plate, the supports, and the cover plate are temporarily combined to facilitate the installation of a soil plate or a stone plate and to prevent separation space from forming between the mattress and the soil plate or the stone plate.
