Embodiment Construction

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. figure 2 is a partial perspective view showing a styrofoam member for a sound-absorbing panel installed in a floor according to an embodiment of the present invention, and image 3 is shown with figure 2 A partial cross-sectional view of an acoustic panel with styrofoam components.

[0031] The styrofoam member 100 for a sound-absorbing panel at a floor according to the present invention has a plurality of holes 102 with a space ratio of 60% to 90% and a dynamic modulus of elasticity of 25MN / m 3 up to 45MN / m 3 . exist figure 2 In the figure, the hole 102 is illustrated as a rectangular shape, but the hole 102 may also be in other shapes, such as a circle, an ellipse, or a polygon other than a rectangle. If the styrofoam member 100 having the above-mentioned space ratio has a dynamic elastic modulus smaller than the lower limit, peo...

Abstract

PURPOSE: A floor impact sound absorbing panel having an expanded polystyrene layer is provided to improve floor impact sound decrease efficiency, lower collapsibility. CONSTITUTION: A floor impact sound absorbing panel having an expanded polystyrene layer comprises a plurality of holes(102) formed to have 60% to 90% space. The expanded polystyrene layer has resilient modulus of 25 to 45. A floor impact sound absorbing panel has the expanded polystyrene layer located on the upper part of a slab layer. A medium density fiberboard which covers a plurality of holes is located on the upper part of the expanded polystyrene layer.

Description

technical field [0001] The present invention relates to a foamed polystyrene member and an acoustic panel having the same. More particularly, the present invention relates to a styrofoam member installed between a slab layer and a finishing mortar layer to minimize transmission of impact sound between floors, and having The sound-absorbing panel of the component. Background technique [0002] Recently, with changes in the building structure due to the use of steel frame structures with higher building floors and reduced slab thickness, inter-floor noise is generated between the upper and lower floors of apartment buildings, which has increased the dissatisfaction of residents . [0003] In order to give a basic solution to eliminate floor crashing noise, the most important thing is to reduce the noise to a minimum level, which however is basically impossible in everyday life. Currently, sound-absorbing panels are installed at floors when building apartment buildings, wher...
