Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a plywood with a good moisture-proof effect comprises a main body 1, a sound insulation structure 5, a first board body 6 and a second board body 7, wherein a moisture-proof structure 2 is arranged on the outer side wall of the main body 1, the moisture-proof structure 2 comprises moisture-proof boards 201, water washing cotton 202 and waterproof breathable films 203, the moisture-proof boards 201 are fixedly connected to the outer side wall of the main body 1, the water washing cotton 202 is arranged inside the moisture-proof boards 201, the waterproof breathable films 203 are arranged inside the moisture-proof boards 201, the moisture-proof boards 201 are provided with two groups, the two groups of moisture-proof boards 201 are symmetrically distributed at the bottom end and the top end of the main body 1, and the water washing cotton 202 is uniformly;

when the plywood is used, most of moisture can be prevented from corroding the interior of the board due to the arrangement of the damp-proof board 201, the water-washing cotton 202 can absorb the moisture permeating into the interior of the damp-proof board 201, meanwhile, the moisture permeation is further prevented due to the arrangement of the waterproof breathable film 203, the interior of the board is protected, and therefore the damp-proof effect of the plywood is improved;

the edge sealing structure 3 is arranged at the peripheral edge of the main body 1, the edge sealing structure 3 comprises a fixing block 301, a thread groove 302, a fixing bolt 303 and a clamping strip 304, the fixing block 301 is embedded at two sides of the first plate body 6, the thread groove 302 is arranged inside the fixing block 301, the fixing bolt 303 is movably connected inside the thread groove 302, the fixing bolt 303 penetrates through the clamping strip 304, the clamping strip 304 is movably connected at the edge of the main body 1, the thread groove 302 and the fixing bolt 303 are in threaded connection, and the clamping strip 304 is arranged in a C shape;

when the plywood is used, the clamping strips 304 are arranged in a C shape, the peripheries of the plates can be tightly pressed together, the separation and scattering phenomena of the plywood are avoided, and the clamping strips 304 are more firmly fixed on the peripheries of the plywood due to the arrangement of the fixing blocks 301 and the fixing bolts 303, so that the plywood is more firmly fixed;

the sound insulation structure comprises a main body 1, a second plate body 7, a first plate body 6, a glue layer 4, a sound insulation structure 5 and spoilers 503, wherein the second plate body 7 is arranged in the main body 1, the first plate body 6 is arranged in the main body 1, the outer side walls of the first plate body 6 and the second plate body 7 are respectively provided with the glue layer 4, the sound insulation structure 5 is arranged in the main body 1, the sound insulation structure 5 comprises the sound insulation plate 501, a cavity 502 and the spoilers 503, the sound insulation plate 501 is arranged between the first plate bodies 6, the cavity 502 is arranged in the sound insulation plate 501, the spoilers 503 are fixedly connected in the cavity 502, the spoil;

during the use, acoustic celotex board 501 and cavity 502's setting has changed the medium of sound wave propagation, has increased the loss of sound wave in the transmission process, and the setting of spoiler 503 simultaneously changes and has disperseed the route of sound wave transmission, has further increased the loss of sound wave propagation, has realized making an uproar falls in the sound insulation of noise to the syllable-dividing effect of this plywood has been improved.

The working principle is as follows: when the waterproof plywood is used, firstly, the plywood is taken out and transported to a target area, then, the board is used, when the use environment is too humid, moisture can corrode the plywood, at the moment, the moisture permeating into the interior of the moistureproof board 201 can be absorbed by the washing cotton 202, and the waterproof breathable film 203 can prevent the moisture from further permeating and protect the interior of the plywood;

secondly, when the plywood is in a high-temperature environment, the expansion phenomenon can occur among the plates, at the moment, the clamping strips 304 are buckled around the plywood to tightly press the plates inside the plywood together, and meanwhile, the fixing blocks 301 and the fixing bolts 303 are arranged to enable the clamping strips 304 to be more firmly fixed around the plywood, so that the separation and scattering phenomena of the plywood are avoided;

finally, when noise passes through the plywood, the medium for sound wave transmission is changed due to the arrangement of the cavity 502, the path for sound wave transmission is changed and dispersed due to the arrangement of the spoiler 503, the loss of the sound wave in the transmission process is increased, sound insulation and noise reduction of the noise are realized, and the plywood is finally used.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
