Abstract
An invention relating to an interlayer sound insulating material is disclosed. The disclosed interlayer sound insulating material includes: a rigid panel having a plurality of air layers; and an anti-resonance part provided between the buffer part and the buffer part which is provided under the rigid panel to absorb impact transmitted from the rigid panel.
Description
The present invention relates to an interlayer sound insulating material, and more particularly, to an interlayer sound insulating material with reduced floor impact sound, improved rigidity and improved workability.
Currently constructed buildings such as apartment houses have foamed foam or foamed plastic laid on the concrete, and waterproof mortar and ondol stone copper pipes are laid on them as a bubble layer, and finished with finishing materials such as plaster and wood.
However, such a structure is transmitted to the lower floor through floor slabs, ceilings or walls when a shock is applied due to human walking or dropping of objects from the upper floors of apartment houses such as apartments, villas and the like.
Such a floor impact sound is largely a heavy impact sound having a high energy of low frequency such as a light impact sound including a high frequency component such as a falling sound of a bowl, a golf ball, a chair, and a moving sound of a desk, an adult walking, Respectively.
The concrete slab, which separates the lower and upper layers, can be said to be primarily responsible for the sound insulation function by blocking the air flow in the upper and lower layers. However, when impact or vibration is applied to the concrete structure with high density, the sound waves are not canceled It has the characteristics that it is transmitted to another generation adjacent to the floor or the wall.
Recently, as the problem of floor noise has become serious in apartment houses, regulations on housing construction standards have been further strengthened and revised. In the above regulations, floor impact sound between each floor should be less than 58 decibel (dB) for light impact sound and less than 50 decibel (dB) for heavy impact sound.
Thus, conventional interlayer flooring structures for minimizing and minimizing the interlayer noise that is significantly raised are disclosed. This conventional conventional interlayer flooring structure has a structure in which a lightweight foamed concrete layer is formed on the basis of a concrete slab, A heating pipe and a mortar layer are formed thereon, and a finishing material layer made of a decorative material such as monolith, wood, or tile is formed thereon.
On the other hand, Korean Patent Laid-Open No. 2005-0045164 (published on May 17, 2005) discloses a "reducing agent for preventing noise between apartment houses ".

In addition, a seating groove portion on which the buffer portion is seated is formed on the bottom surface of the rigid panel.
Further, the buffering portion is characterized by being made of a polyurethane material.
The buffer portions are spaced apart from each other and have an interval of 100 mm or more and 250 mm or less.
The sound insulating layer according to the present invention has an effect of improving the sound insulation performance by forming an air layer of a polygonal block shape on the rigid panel in an embossed or embossed form, as well as forming a plurality of nodal points, thereby improving the workability.
Further, according to the present invention, a seating groove portion is formed on the bottom surface of the rigid panel, so that the fixing position of the buffer portion can be designated, and the buffer portions can be arranged at regular intervals, thereby improving quality and workability.

Here, the light impact sound is applied to the lightweight foamed concrete on the average, and the size is 200 to 300 Newtons on the average, whereas the heavy impact sound has a spatially concentrated force of 4000 Newtons. Therefore, the impact of the lightweight impact sound is greater as the
In addition, the heavy impact sound has a large applied force locally, so that the shock absorber 120 causes a large deformation and hardly acts as a spring. The more flexible the
