Description
Technical Field
The utility model relates to a panel processing technology field, concretely relates to shock-absorbing compound multiply wood of making an uproar falls.
Background
The multilayer board, also called plywood, is a three-layer or multilayer board which is formed by rotary cutting log sections or slicing thin veneers from wood squares, and gluing the veneers through an adhesive and high-temperature pressing. The fiber directions of the single plates of the adjacent layers are mutually vertical, and the surface plate and the inner plate are symmetrically arranged on the assembly structure at the two sides of the central layer, so that the composite material has the advantages of small physical and mechanical property difference in the longitudinal and transverse directions, high strength and the like. The multi-layer board is one of common furniture materials, is one of three large boards of an artificial board, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like.
When present multiply wood was used as the partition wall of room fitment, its syllable-dividing effect is poor and crashproof effect is general, causes easily when children play to bump, needs to improve.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a damping composite multilayer board falls makes an uproar to improve the syllable-dividing effect and the crashproof performance of multiply wood, and then promote the performance of multiply wood, satisfy the user demand.
In order to solve the technical problem, the utility model provides a noise-reducing and shock-absorbing composite multilayer board, which comprises a bottom board layer, a sound-insulating board layer, a sound-absorbing board layer, a foaming layer and a surface board layer from bottom to top;
the upper surface of the sound-absorbing board layer is provided with diamond-shaped bulges, and the tops of the diamond-shaped bulges are paved with a sound-absorbing fiber layer;
the cross section of the foaming layer is of a honeycomb structure.
And filling blocks corresponding to gaps between adjacent rhombic bulges are arranged on the lower surface of the sound absorption fiber layer.
Wherein, the filling block and the sound absorption fiber layer are integrally processed and formed.
Wherein, a plurality of horn-shaped through holes are arranged on the sound insulation board layer;
and a sound insulation paper layer is filled in the horn-shaped through hole.
Wherein, the thickness of the foaming layer is 2-3 mm.
Wherein, the panel layer is provided with micropores.
The utility model has the advantages that:
1. the cushioning property of the plate is improved by adding the foaming layer, so that the hard collision caused by external force impact is reduced, the cushioning effect is good, and the anti-collision effect is good;
2. repeated refraction and adsorption of the sound volume are formed through the diamond-shaped bulges on the sound-absorbing plate layer and the filling blocks below the sound-absorbing fiber layer, so that the sound-reducing effect is improved, and the sound-absorbing volume is not influenced even if the overall thickness of the plate is reduced;
3. the micropore on the panel layer can enable external sound volume to quickly enter the panel body, and meanwhile, the defect that echo is generated indoors is overcome.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention;
FIG. 2 is a schematic view of the surface structure of the sound absorbing sheet layer of the present invention;
fig. 3 is a schematic view of the structure of the sound-absorbing fiber layer.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, the present embodiment provides a noise-reducing and shock-absorbing composite multilayer board, which includes a bottom board layer 1, a sound-insulating board layer 2, a sound-absorbing board layer 3, a foaming layer 4 and a surface board layer 5 from bottom to top, and the foaming layer 4 improves the cushioning property of the board, prevents external force from affecting impact, and improves the use safety; simultaneously, when the outside noise production, through inhaling the realization of sound layer 3 and inhaling the sound, realize giving sound insulation through syllable-dividing sheet layer 2, improved and inhaled sound and syllable-dividing effect, improve the feature of environmental protection of noise control sound.
The upper surface of the sound-absorbing board layer 3 is provided with the diamond-shaped protrusions 31, the top of each diamond-shaped protrusion 31 is laid on the sound-absorbing fiber layer 6, and the diamond-shaped protrusions 31 can increase the sound volume concentration and reduce the sound volume penetrability, so that the sound volume absorption is further increased;
the cross section of the foaming layer 4 is of a honeycomb structure, so that the elasticity is improved, and the buffering effect is enhanced.
Further, the lower surface of the sound absorption fiber layer 6 is provided with a filling block 61 corresponding to a gap between adjacent rhombic protrusions 31, the filling block 61 and the sound absorption fiber layer 6 are integrally processed and molded, the filling block 51 and the rhombic protrusions 31 jointly form absorption on volume, absorption capacity is increased, repeated absorption on volume is achieved, and the absorption effect of the sound absorption plate is 3-5 times that of an existing common sound absorption plate.
Further, a plurality of horn-shaped through holes 21 are formed in the sound insulation board layer 2; loudspeaker type through-hole 21 intussuseption is filled with soundproof paper layer 22, when inhaling sound sheet layer 3 and having less omission to the volume, further gives sound insulation through soundproof sheet layer 2, prevents the volume conveying.
Further, the thickness of the foaming layer 4 is 2-3 mm.
Further, the panel layer 5 is provided with the micropores 51, and the micropores can rapidly transmit the sound volume of the space to the interior of the multilayer board for recycling, so that echoes are prevented.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
