Description
[0001] The present invention relates to a sound insulating member installed to reduce noise transmitted through a floor and a bottom structure using the same, and more particularly, to a floor structure using a flat panel and a pair of concave- The present invention relates to a sound insulating member for noise reduction of an interlayer that can effectively block interlayer noise, and a bottom structure which preferably uses the sound insulating member.
Generally, apartment houses are continuously increasing due to increase of efficiency of land use and ease of housing supply. Such apartment houses are characterized by the fact that many households have a vertical arrangement structure, so that due to the interlayer noise among neighboring households, And many attempts have been made to reduce such interlayer noise.
The main cause of the above-mentioned interlayer noise is a floor impact sound, which can be divided into a light impact sound and a heavy impact sound. Here, the light impact sound is a light and hard material such as a sound of a small object falling off a furniture or a sound of a short duration, and a heavy impact sound has a large impact force and a long duration .
The floating floor structure is applied as the most general method for improving the sound insulation performance against the floor impact sound as described above. The floating floor structure is provided with a cushioning material capable of performing vibration insulation between the structural slab and the finish layer. , A cushioning material 10 'is disposed on the slab S', and a foamed concrete layer 20 'and a mortar layer 30' are formed on the slab S '. This floating floor structure is generally composed of 210 mm of slab S ', 30 mm of
On the other hand, the floating floor structure is provided with a cushioning material capable of performing vibration insulation between the structural slab and the finish layer. The cushioning material for the lightweight impact sound is a cushioning material having a small spring constant (N / While the cushioning material for heavy impact sound is required to have a high rigidity, a closed structure, a high density structure and a weighted property.
The residual deformation of the floor impact noise reducing material is measured according to the test method specified in
SUMMARY OF THE INVENTION The present invention has been devised to overcome the above conventional problems, and it is an object of the present invention to provide a panel member having a predetermined thickness and a concave- And an object of the present invention is to provide a sound insulation member for noise reduction of an interlayer which can efficiently satisfy the effect.
According to an aspect of the present invention, there is provided a sound insulating member installed between a floor slab and a floor covering to reduce noises generated between a floor and a floor, The first panel part is a member positioned at the lower part. The upper surface is flattened and the lower surface is continuously formed at a predetermined interval And the second panel portion is a member coupled to the first panel portion and has a three-dimensional shape in which the upper and lower surfaces are all flattened. Thereby providing a sound insulating member for abatement.
Further, the present invention is characterized in that the first and second panel portions of the sound insulating member are made of the bead method heat insulating material and each have a thickness of 20 mm, and the density of the first panel portion is smaller than the density of the second panel portion. Thereby providing a sound insulating member for noise reduction.
The present invention minimizes the area where the lower surface of the sound insulating member is embossed and embossed in an embossed form and minimizes direct contact with the floor slab, and minimizes the transmission of vibrations and noise generated in the upper layer to the lower layer by forming the air layer.
At this time, the convex portion of the lower surface absorbs impact acting from the top to the bottom, thereby further improving the blocking effect on the heavy impact sound.
Further, according to the present invention, since the sound insulating member has two divided structures, transmission of vibration and noise is further suppressed. In this case, it is easy to work by joining the two divided panel members by a simple lamination method.
In addition, the density of the panel member located at the lower part is made smaller than the density of the panel member stacked at the upper part, so that the effect is dispersed as the upper impact or noise progresses downward.
