Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention is further described with reference to fig. 1-2.

A sound insulation LVL plate comprises an upper plate layer 11, a middle plate layer 13 and a lower plate layer 12 which are sequentially arranged, wherein the middle plate layer 13 comprises a sound insulation layer 3 and protection plates 131 arranged on the upper surface and the lower surface of the sound insulation layer 3, the sound insulation layer 3 comprises a middle core layer 31, a plurality of sound insulation holes 311 are arranged on the middle core layer 31, and sound absorption layers 32 are further arranged on the upper surface and the lower surface of the middle core layer 31; go up sheet-metal layer 11 and lower sheet-metal 12 and constitute by many veneers, guard plate 131 also can constitute by many veneers, consequently, when using, the sound wave is in conduction to puigging 3 department, because puigging 3 includes middle sandwich layer 31 and sound absorbing layer 32, consequently, the sound wave is when passing through sound absorbing layer 32, can be by effectual weakening, simultaneously when separating sound hole 311, can be further weakened, consequently, the furniture of making can play good syllable-dividing effect, guard plate 131's existence simultaneously, also can effectual strengthening puigging 3's structural strength, make the furniture of making not fragile.

Further, middle sandwich layer 32 comprises a plurality of veneers, syllable-dividing hole 311 pierces through middle sandwich layer 31, syllable-dividing hole 311 is including the syllable-dividing pore that the symmetry set up, the section in syllable-dividing pore is isosceles trapezoid shape, consequently when the sound wave separates sound hole 311, because the section in syllable-dividing pore is isosceles trapezoid shape, consequently the sound wave is when the pore that gives sound insulation, can produce the reflection, and simultaneously, because middle sandwich layer 31 comprises a plurality of veneers, consequently the sound wave is when passing through the veneer junction, the direction of reflection is inconsistent, further play the effect of weakening to the sound wave, the effect of giving sound insulation has further been strengthened.

Further, it includes the backup pad to inhale sound layer 32, the backup pad comprises many veneers, be equipped with in the backup pad and inhale sound hole 322, it is filled with glass fiber to inhale sound hole 322 intussuseption, it sets up with syllable-dividing hole 311 is crisscross to inhale sound hole 322, glass fiber's existence makes the sound wave when inhaling sound layer 32, the continuity of sound wave is broken, consequently, can play good syllable-dividing effect, inhale sound hole 322 and syllable-dividing hole 311 crisscross setting simultaneously, make the elimination effect to the sound wave more comprehensive, the effect of giving sound insulation has further been strengthened.

Further, the sound absorbing hole 322 is a blind hole, so that the support plate can have a good sound insulation effect while maintaining a certain strength.

Further, the grain direction of the guard plate 131 is perpendicular to the grain direction of the support plate, thereby making the structural strength of the entire panel greater.

Further, the support plate is also provided with an auxiliary muffling hole 321, thereby further enhancing the soundproof effect.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
