▎ 摘　　要

NOVELTY - Leveling and preparing elastic sound-insulating floor slab, comprises (a) using laser scanning to obtain the height difference and distribution of the floor, modeling on the computer and arranging in a grid; (b) dividing the floor into grids, and arranging damping springs on the floor; (c) using graphene elastic sound insulation mortar to level the floor to form graphene elastic sound insulation mortar layer; (d) spraying interface agent on graphene elastic sound insulation mortar layer, and forming interface layer; and (e) laying a 1-6 mm thick elastic sound-insulating coating on the interface layer. USE - The method is useful for leveling and preparing elastic sound-insulating floor slab. ADVANTAGE - The method enables realizing grid division and height scale function through the damping spring, thus effectively solving the leveling layer quality control problem, combined with spring damping sound insulation graphene elastic sound insulation and elastic sound-insulation comprehensive effect, and forming a high-efficiency sound insulation system of the floor, meeting the development requirement of the green building. DESCRIPTION OF DRAWING(S) - The drawing shows a floor sound insulation elastic coating leveling system in elastic sound-insulating floor slab and the damping spring arranged on the gridded floor. 2Damping spring
