A floor impact noise reducing structure of a multi-storied building is provided to fulfill the heat-insulating function and the damping function by integrating a structure having the damping function with an insulating material on a floor slab layer. The invention relates to a floor impact noise reducing structure of a multi-storied building for absorbing and reflecting impact energy and fulfilling the heat-insulating function sufficiently by forming plural spaces(1a) having a size of 5mm or more on a structure(1) which comes in contact with a floor slab layer(2) on the soft part and placing an insulating material(3) made of vermiculite, foam chemicals or the by-products, or the crushed chips to each space, forming a hollow layer(4) on the upper part of the insulating material built in the space to prevent the transfer of heavyweight impact sound to the floor slab layer, forming a cellular concrete layer by locating a board(5) made of one of metal or high-density inorganic substance or inorganic chemicals, artificial wood, wood wool, wood particle-cement, synthetic resins or thick paper on the upper part of the structure and filling up with cellular concrete(6), and forming an ondol layer by arranging pipes(7) and filling up with mortar(8). |
