One embodiment of the present invention will be described based on the drawings. FIG. 1 shows a cross-sectional view perpendicular to the board surface of the present sound insulation laminate, with a density of 9.
A hexagonal cylindrical honeycomb core core material (2) made of kraft paper with a thickness of 25m5+ was laminated with an appropriate adhesive on both sides of a high-density glass wool board (1) with a weight of 6 kg/m3 and a thickness of 12+ stories. The upper part of the opening surface of the honeycomb core is filled with plaster as a partial weighting material (3), which hardens to cover the surface of the honeycomb core.

Further, a soft polymer sheet (4) is adhesively laminated thereon using an appropriate adhesive, and a plywood (5) is adhesively laminated on the surface.

As high-density glass wool, the density is 60 kg/m3
If it is less than this, the sound insulation effect, which is the object of the present invention, will be poor, the thickness will become unnecessarily thick, and the rigidity will also decrease, which is not preferable. The thickness of the high-density glass wool is preferably 9 to B degrees for handling purposes. Of course, a sound absorbing board such as rock wool with similar performance may be used instead of glass wool.

In addition, honeycomb cores (which are laminated on both sides of glass wool)
As for 2), a kraft paper with specifications for general building materials is used, and a thickness of about 25III is preferable for handling. Similar structure instead of honeycomb core,
For example, it is possible to use a structural core material similar to a honeycomb core, such as one in which corrugated boards are laminated continuously in the direction perpendicular to the board surface, or a structural material in which a continuous cylindrical aggregate is used instead of a hexagonal honeycomb. can. As the partial filler (3) to be filled from the opening surface of each honeycomb core, in addition to the above-mentioned plaster, asphalt and concrete mortar can also be used. In this method of filling the partially molded material, a continuous area on the core surface may be filled, or it may be filled in a scattered manner in blocks.

In this case, it is necessary that the single or total filling area is in the range of 25 to 75% of the total surface area of the core material. If the filling area is outside this range, the sound insulation loss caused by the disproportionality of the surface density, which will be described later, will be leveled out.

The decentralization effect will be poor. In addition, the filling with the partially weighted material is the total surface density of the soft polymer sheet and plywood that are MtNed on the surface of the core material, and the area filled with the partially weighted material is 1% of the area that is not filled with the material. .It must be at least twice as large. This is because if this areal density ratio is less than 1.2, the desired effect of improving sound insulation defects cannot be obtained.

It is a material with excellent sound insulation properties, and in the present invention, a material with an areal density of 1.5 kg/m2 or more and a thickness of l
It is preferable for handling to be close. If the areal density is less than the above, the sound insulation properties will be poor, and the thickness will be too thick to obtain the same sound insulation effect, which is not preferable because the handleability will be poor.

Function: In the present invention, (a) soft polymer sheets are arranged on both sides of the high-density glass wool at appropriate intervals, thereby forming a double wall that is effective for soundproofing. (b) High-density glass wool is inserted as a sound absorbing material in the middle. (C) Solid sound propagation is suppressed by elastic glass wool and soft polymer sheet. Furthermore, as (d), the applicant has filed Japanese Patent Application No. 58-115192 "Sound Insulating Structure"
As disclosed in 2007, a panel board is composed of multiple regions with different natural frequencies, and the areal density of the board material is varied so that each region exhibits different acoustic behavior from the others, and furthermore, it is possible to reduce the amount of transmitted sound due to sound insulation defects. In order to suppress the sound insulation loss level, the sound insulation loss frequencies of each part of the area are separated appropriately, and the transmitted energy is also reduced to a level corresponding to the area of each part, thereby achieving the dispersion and leveling of the sound insulation loss.

In this way, an acoustic reinforcement effect is achieved, and the synergistic effect of the soft polymer sheet and the sound absorbing material increases the light weight of the honeycomb core.
This provides excellent soundproofing properties without significantly impairing flexibility and size flexibility.
