Description

Build soundproof construction plate
Technical field
The present invention relates to building panel fields, specially building soundproof construction plate.
Background technique
Sound is a kind of wavy energy, needs medium that could propagate.Sound is in same Propagation, Media density Bigger, spread speed is faster.For example the spread speed in normal temperature air is about 340 meter per seconds, the spread speed in rail is about For 5200 meter per seconds.Another propagate of sound is exactly across medium propagation.I.e. from a kind of medium, critical across two media is connect Contacting surface enters another medium, at this point, the transmitting essence of sound energy is the transmitting of Oscillation Amplitude.When across medium propagation, two media Density difference it is bigger, sound can loss it is bigger.And in practical application, air be mankind's normality under activity space, then with sky Air tightness differ bigger material be generally the very high material of density (than atmospheric density, also much lower material is in addition to vacuum, It is also genuine few), that is, it can be considered acoustic material, density is higher, and soundproof effect is better.It constructs and fits up during building Noise can be inevitably generated on the way, often influences whether the life of construction surrounding resident, thus it is proposed that building soundproof construction plate.
Summary of the invention
The purpose of the present invention is to provide building soundproof construction plates, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
Build soundproof construction plate, including wood composite board, the wood composite board is internally provided with centrifugally glass-wool, it is described from Heart mineral wool is internally provided with abatvoix, and the abatvoix is internally provided with cystosepiment, the inside setting of the cystosepiment There is plate core, the wood composite board is equipped with card slot and protruding block, and the card slot and protruding block mutually coincide, and card slot and protruding block Mutually an identical side surface is provided with building panel glue.
Preferably, the wood composite board with a thickness of 20-25mm.
Preferably, the plate core is evacuated panel, and with a thickness of 15-20mm.
Preferably, several holes are distributed in the inside of the abatvoix.
Preferably, the outer surface of the wood composite board is adhesive with lkd layer.
Compared with prior art, the beneficial effects of the present invention are: the present invention has added puigging in the inside of wood composite board Cystosepiment and sound absorbing layer abatvoix, centrifugally glass-wool and vacuum layer so that when sound enters generate isolation and absorb Effect, to achieve the effect that sound insulation；Secondly the card slot and protruding block of setting can splice fixation by building panel glue, so that Building panel can be split, and be moved easily and spliced.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is rotating ball of the present invention and spherical groove connection schematic diagram.
In figure: 1 wood composite board, 11 centrifugally glass-wools, 12 cystosepiments, 13 abatvoixs, 14 plate cores, 2 card slots, 3 protrusions Block.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2:
Build soundproof construction plate, including wood composite board 1, wood composite board 1 with a thickness of 20-25mm, wood composite board 1 it is outer Surface is adhesive with lkd layer, so that building panel is more beautiful, the bite for being also prevented from insect is destroyed, and preferably protects building Plate, wood composite board 1 are internally provided with centrifugally glass-wool 11, and 11 internal fiber of centrifugally glass-wool is fluffy staggeredly, exists a large amount of Small hole is typical porous sound-absorbing material, has good sound absorption characteristics, and since 11 quality of centrifugally glass-wool is soft It is soft, fiber is fine, and skin will not be stimulated in construction, be the preferred product of insulation.
Centrifugally glass-wool 11 is internally provided with abatvoix 12, and abatvoix 12 is polyester fibre acoustic panel, and abatvoix 12 has Have sound-absorption and heat-insulation heat preservation property, and plate is uniform in material solid, high resilience, toughness, wear-resisting, shock resistance, it is tear-resistant, be not easy It scratches, several holes, the acoustical absorbance properties class of polyester fibre acoustic panel and other porous materials is distributed in the inside of abatvoix 12 Seemingly, sound-absorption coefficient increases with the raising of frequency, and the sound-absorption coefficient of high frequency is very big, back leave a blank chamber and with it constitute sky Between acoustic(al)absorbent be greatly improved the sound absorption qualities of material so that the better sound insulation of building panel.
Abatvoix 12 is internally provided with cystosepiment 13, and cystosepiment 13 protects constructure body structure, and extension is built The object service life is built, since external thermal insulation is will to keep the temperature to be placed on the outside of structure, reduces the production of the malformation as caused by temperature change Raw pressure, and the erosion of harmful substance and ultraviolet light to structure in air is reduced, cystosepiment 13 also effectively plays sound insulation Effect.
Cystosepiment 13 is internally provided with plate core 14, and plate core 14 is evacuated panel, and with a thickness of 15-20mm, the propagation of sound Medium is needed, sound cannot be propagated in a vacuum, and sound cannot be propagated in evacuated panel again, the building panel plate core 14 setting Evacuated panel realizes the effect of sound insulation.
Wood composite board 1 is equipped with card slot 2 and protruding block 3, and card slot 2 and protruding block 3 mutually coincide, and card slot 2 and protruding block 3 Mutually an identical side surface is provided with building panel glue 7, and the card slot 2 and protruding block 3 of setting can be spliced by building panel glue 7 It is fixed, building panel is split, is moved easily and splices.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
