The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figures 1 and 2, have a plurality of through holes 11 on the top layer gypsum plank 1 of sound absorption PLASTIC LAMINATED of the present utility model, described a plurality of through hole 11 is the hole of a combined shaped, described combined shaped is comprised of a rectangle and two semicircles, described two semicircles are docked at respectively on two opposite side of described rectangle, form the shape that is similar to runway.Described and in specific implementation process, for the good looking appearance of described top layer gypsum plank 1, be provided with a plurality of grooves on the surface of described top layer gypsum plank 1, corresponding several through holes 11 of each groove part.
Wherein, when specific implementation, the shape of described through hole 11 also can be circular, oval, square, triangle, rhombus etc., and corresponding different demand and practical situations can take different shapes.
And as shown in Figures 3 and 4, having a plurality of logical holes 21 on the bottom gypsum plate 2 of sound absorption PLASTIC LAMINATED of the present utility model, described a plurality of logical holes 21 are circular opening.
Equally, when specific implementation, that the shape in described logical hole 21 also can be set to is square, oval, triangle, rhombus etc., and corresponding different demand and practical situations also can take different shapes.
Fig. 5 is the structural representation of sound absorption PLASTIC LAMINATED of the present utility model, and Fig. 6 is the sectional view along the C-C line of Fig. 5.In specific implementation process, described top layer gypsum plank 1 and described bottom gypsum plate 2 are close to combination mutually, and are fixed together, and so that each through hole 11 is all corresponding one by one with a logical hole 21.Thus, an integral slab that is compounded to form by described top layer gypsum plank 1 and described bottom gypsum plate 2 is sound absorption PLASTIC LAMINATED of the present utility model.Described sound absorption PLASTIC LAMINATED utilizes that described through hole 11 and described logical hole 21 are corresponding one by one just to have formed a up and down acoustical board of two-layer difformity trepanning, thereby can access best acoustically effective.Wherein, for so that those skilled in the art understand the utility model more, each layer with described sound absorption PLASTIC LAMINATED in the present embodiment all has been presented among Fig. 5.
Add that again the material that sound absorption PLASTIC LAMINATED of the present utility model is used is the gypsum material, and the performance of the fire protection flame retarding of gypsum can reach the at present standard of domestic A level fire protection flame retarding to indoor building material fully, and its effect is far superior to the effect of the fire protection flame retarding of traditional wooden acoustical board.
To sum up, the utility model is when guaranteeing acoustically effective, the ability that also has very strong fire protection flame retarding, with respect to traditional wooden acoustical board, sound absorption PLASTIC LAMINATED of the present utility model is more applicable in the modern architecture requirement to the high fire retardant performance of acoustical board.
Simultaneously, when concrete the application, in order to obtain better acoustically effective, the area of each described through hole 11 all can be set to be less than or equal to the area in corresponding described logical hole 21, and the central point of each described through hole 11 also all is set to be positioned on the straight line with the central point in corresponding described logical hole 21, thereby so that each described through hole 11 is fully corresponding with corresponding described logical hole 21, thereby so that described sound absorption PLASTIC LAMINATED meets the Principles of Acoustics of sound absorption more, and then so that described sound absorption PLASTIC LAMINATED has stronger acoustical absorptivity.And the Principles of Acoustics of above-mentioned setting and sound absorption all belong to known technology in this area, just repeat no more at this.
Wherein, described top layer gypsum plank 1 has a first surface 12 and a second surface 13, described bottom gypsum plate 2 has a first surface 22 and a second surface 23, the second surface 13 of described top layer gypsum plank 1 is connected with the first surface 22 of described bottom gypsum plate 2, and the described a plurality of grooves in Fig. 1 just are arranged at the first surface 12 of described top layer gypsum plank 1.In the present embodiment, in order further to strengthen the acoustical absorptivity of described sound absorption PLASTIC LAMINATED, described sound absorption PLASTIC LAMINATED also comprises two coating, described two coating are mutually bonding with the second surface 23 of the second surface 13 of described top layer gypsum plank 1 and described bottom gypsum plate 2 respectively, and described two coating all can all cover respectively the second surface 13 of described top layer gypsum plank 1 and the second surface 23 of described bottom gypsum plate 2.Like this, all can form the sound absorption cavity between coating and through hole 11 and coating and the logical hole 21, thus can sound wave by the time formation circle round, further promote acoustically effective.Certainly, when practical application, also can be only at the second surface 13 of described top layer gypsum plank 1 or bonding described coating on the second surface 23 at described bottom gypsum plate 2 only.
And described coating can be other felt, the clothes such as glass mat or nonwoven, and described coating has acoustically effective, so just can further optimize the acoustically effective of described sound absorption PLASTIC LAMINATED.
Wherein, in specific implementation process, the mode that is fixedly connected with between described top layer gypsum plank 1 and the described bottom gypsum plate 2 can for bonding, be spirally connected or the mode such as snapping.Simultaneously, be less than or equal at the area that guarantees described through hole 11 under the prerequisite of area in corresponding described logical hole 21, size to the aperture in described through hole 11 and described logical hole 21 can be regulated, the logical hole of these through holes also can form various patterns, these all can be decided on practical situations, just repeat no more at this.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
