This plywood has good absorbing sound and lowering noise function, and through hole, sound-absorption hole and sound absorbing layer corresponding with sound-absorbing groove on sound-absorbing groove on upper layer of wood, panel layer form a sound-absorbing system, effectively absorb noise.
As preferably, the length of described sound-absorbing groove is consistent with the length of upper layer of wood.
As preferably, described sound absorbing layer is aluminum fiber sound absorbing layer or Wooden sound-absorbing layer.
Further, described enhancement Layer includes that multiple cross reinforcing and vertical strengthening ribs, described cross reinforcing and vertical strengthening ribs infall are connected by screw.Cross reinforcing and vertical strengthening ribs all can use flat aluminum alloy bar, improve the overall construction intensity of plywood.
Further, described plywood body is formed around a circle protective frame, and the cross section of described protective frame is U-shaped, and described protective frame height is consistent with plywood body thickness, and protective frame medial surface is glued with plywood body.Protective frame has protective effect to plywood body, it is to avoid adjacent plywood phase mutual friction is impaired, reduces the collision dynamics between plywood, it is to avoid the wasting of resources.
Further improving as in structure, have rubber layer between described protective frame medial surface and plywood body, described rubber layer height is highly consistent with protective frame.The rubber layer being arranged between protective frame medial surface and plywood body has certain cushioning effect, further enhancing protection effect of protective frame, reduces collision dynamics.
The beneficial effects of the utility model: this fire-retardant acoustic mastic plywood that this utility model provides, simple in construction, easy to use, there is the most waterproof, fire-retardant and sound-absorbing effect, and intensity is higher, tensile strength and rupture strength are higher, and combination property is preferable.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
Embodiment 1:
One fire-retardant acoustic mastic plywood as shown in figs. 1 and 3, including plywood body 1, described plywood body 1 includes passing sequentially through glue-line bonding panel layer 1.1, sandwich layer and backplane level 1.8 together from top to bottom, and described sandwich layer includes layer of wood 1.3, lower layer of wood 1.6 and the magnesite gelling flame-retardant layer 1.5 being bonded between layer of wood 1.3 and lower layer of wood 1.6；
Described panel layer 1.1 lower surface is provided with polyurea layer 1.2, it is provided with sound absorbing layer 1.4 between described upper layer of wood 1.3 and magnesite gelling flame-retardant layer 1.5, the surface that described upper layer of wood 1.3 contacts with polyurea layer 1.2 is provided with at least two sound-absorbing groove 2, described panel layer 1.1 surface offers multiple through hole 5, is provided with the sound-absorption hole 3 being connected with sound absorbing layer 1.4 bottom described sound-absorbing groove 2；It is provided with enhancement Layer 1.7 between described lower layer of wood 1.6 and backplane level 1.8.
The plywood that this utility model provides is provided with polyurea layer 1.2, fine and close, connect seamless, it is possible to isolation moisture in air and oxygen, there is water-tight corrosion-proof bilayer effect.Sandwich layer uses three-decker, and magnesite gelling flame-retardant layer 1.5 is set in intermediate layer, this magnesite gelling flame-retardant layer 1.5 is with calcareous material and magnesium cement as stock, and it is equipped with natural fiber enhancing, through the decorative board material of a kind of lightweight of roll-in, its using method is identical with timber board, can by sawing, dig, the processing technique such as nail, with the layer of wood new structural panel of composition, equally saw, dig, the processing such as nail；And there is insect protected, fire-retardant, high temperature resistant, absorb sound shockproof, waterproof and dampproof, lightweight anticorrosion premium properties.
