Detailed Description

The technical solution of the present utility model will be further described with reference to fig. 1 to 2 by means of specific embodiments.

Example 1:

the composite sound-absorbing and noise-reducing ecological plate shown in fig. 1 comprises: first wood sheet layer 1, second wood sheet layer 2, locating pin 11, first decoration rete 5, inhale the sound cotton layer 6 and first buffer layer 4, first wood sheet layer 1 parallel arrangement is in the top of second wood sheet layer 2, inhale the sound cotton layer 6 and fill between first wood sheet layer 1 and second wood sheet layer 2, in this embodiment, inhale the sound cotton layer 6 and adopt polyester to inhale the sound cotton, can carry out the absorption of noise, weaken the noise of arriving second wood sheet layer 2 from first wood sheet layer 1.

The adhesive can be smeared on the bottom surface of the first wood plate layer 1 and the top surface of the second wood plate layer 2, the sound absorbing cotton layer 6 is fixed, and the strength of the composite structure is improved. In this embodiment, the first wood ply 1 and the second wood ply 2 are made of plywood, and the plywood generally includes three or more layers of veneer, and the veneer is glued by an adhesive, so that layered noise reduction is facilitated while structural stability is ensured.

In this embodiment, the first buffer layer 4 is disposed on the top surface of the first wood board layer 1, and the first decorative film layer 5 is disposed on the top surface of the first buffer layer 4, which may be fixed by using an adhesive. The first decorative film layer 5 can adopt wood grain paper, thereby improving the decoration. For the noise vertically entering the first decorative film layer 5 and the first buffer layer 4, the lateral propagation and attenuation of part of the noise can be performed through the first buffer layer 4, and the noise reaching the first wood ply 1 can be attenuated.

In order to promote the structural strength of first wood sheet layer 1 and second wood sheet layer 2 the array is provided with through-hole 8 on the sound absorbing cotton layer 6, first wood sheet layer 1 bottom surface indent is provided with first locating hole 7 with through-hole 8 one-to-one, second wood sheet layer 2 top surface indent is provided with the second locating hole 9 with through-hole 8 one-to-one, locating pin 11 sets up in first locating hole 7 and runs through-hole 8 downwards in order to extend to in the second locating hole 9, carries out the location and the support of first wood sheet layer 1 and second wood sheet layer 2 through locating pin 11, promotes compressive strength.
