The composite laminate of the utility model realizes the purpose of sound absorption and noise reduction by arranging the sound absorption pore canal, and can be manufactured completely in the delivery stage, thereby reducing the use of a sound insulation layer in the home decoration process, lowering the home decoration cost and shortening the construction period.
Description
Technical Field
The utility model relates to the technical field of composite boards, in particular to a sound-absorbing and noise-reducing composite board.
Background
The composite board is widely applied to the field of home decoration, and can be applied to manufacturing floors, wall decoration and cabinets.
In the house ornamentation, the assembly of current wall body and floor all falls the aspect of making an uproar through setting up the puigging and realizes, and the puigging is foam puigging or reaches the purpose that gives sound insulation through setting up the keel frame, and the setting of puigging often has increased house ornamentation cost, also makes assembly period greatly increased simultaneously.
Disclosure of utility model
The utility model aims to provide a composite laminate with sound absorption and noise reduction effects.
In order to achieve the above purpose, the utility model provides a sound-absorbing and noise-reducing composite laminate which is a multi-layer solid wood composite structure and is a multi-layer solid wood composite structure;
Inside the composite laminate, a plurality of sound absorbing holes are uniformly formed at equal intervals along the length or width direction of the composite laminate.
Further, the composite laminate comprises a log thick plate and a composite plate;
The log thick plate is adhered to the surface of the composite board, and a plurality of sound absorption holes are formed in the surface of the composite board facing one side of the log thick plate at equal intervals.
Further, the composite board is formed by combining and bonding 9 layers of log thin plates.
Further, the thickness of the log plank is 4-6 log plank layers.
Further, the height of the sound absorbing duct is the thickness of three log sheets.
Further, the sound absorption pore canal is realized by grooving the surface of the composite board.
Further, sound absorbing duct is formed by laying a plurality of raw wood thin plates at a certain interval.
Furthermore, the log thick plate is a whole log plate or is formed by seamlessly splicing a plurality of log plates.
Compared with the prior art, the utility model has the advantages that:
1. The composite laminate of the utility model realizes the purpose of noise reduction by arranging the sound absorption pore canal, and can be manufactured completely in the delivery stage, thereby reducing the use of the sound insulation layer in the home decoration process, reducing the home decoration cost and shortening the construction period.
2. The composite laminate reduces the use of wood and the cost of the laminate due to the arrangement of the suction pore channels.
3. According to the composite laminate, the log thick plate is arranged on the end face, so that the strength of the plate after the pore canal is formed is ensured.
4. The suction pore canal of the composite laminate can be formed by equipment excavation, can be realized by the interval arrangement of the plates, and is suitable for various industrial production.
Drawings
FIG. 1 is a schematic view showing the overall structure of a sound-absorbing and noise-reducing composite laminate according to embodiment 1 of the present utility model;
fig. 2 is a schematic view showing the surface structure of the composite board in example 1 of the present utility model.
Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be further described below.
Example 1:
The utility model provides a sound-absorbing and noise-reducing composite laminate, which is formed by bonding 9 layers of log thin plates 1 and one layer of log thick plates 2 as shown in figure 1. Wherein 9 layers of log lamellae 1 are glued to form a one-piece composite board.
As shown in fig. 2, a plurality of equidistant sound absorbing holes 3 are dug on the surface of the composite board, and the thickness of the sound absorbing holes 3 is 3 layers of log thin plates; in the present embodiment, the thickness of the raw wood thick plate 2 is 5mm, and the thickness of the raw wood thin plate 1 is 1mm; the log thick plate 2 can be a whole log plate or a plurality of log plates which are spliced in a seamless way; in the actual use process, the sound absorption pore canal 3 can effectively absorb noise from the surface of the composite laminate, so that the use of wood is reduced, and the cost of the laminate is reduced; thereby reducing the use of the sound insulation layer in the home decoration process, reducing the home decoration cost and shortening the construction period. The log thick plate 2 with the thickness of 5mm can also provide certain strength requirements for the plate after the pore canal is formed.
Example 2:
Example 2 is similar to example 1 in overall structure except that the sound absorbing duct 3 of example 1 is formed by grooving the surface of the composite board, and a corresponding grooving apparatus is required.
The slots in the embodiment 2 are formed by paving three layers of log thin plates 1 above the composite board at equal intervals, wherein the intervals are the widths of the suction holes 3, so that the preparation of the sound-absorbing and noise-reducing composite laminate can be realized in factories without grooving equipment.
The foregoing is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art will make any equivalent substitution or modification to the technical solution and technical content disclosed in the utility model without departing from the scope of the technical solution of the utility model, and the technical solution of the utility model is not departing from the scope of the utility model.
