Abstract
The utility model discloses a sound-proof board, this sound-proof board are formed by top layer, light sound-proof material's intermediate level and bottom bonding in proper order, and the top layer sets up honeycomb through-hole, and the bottom sets up honeycomb blind hole. The middle layer can be made of polyurethane foam, the surface layer can be made of a hollow molded plastic plate, and the blind holes in the bottom layer can be blind holes formed after the plastic plate is subjected to hot pressing, punching and stretching. The sound insulation board can be used for sound insulation walls on expressways.
Description
The utility model relates to the isolated protection of building, particularly relates to a kind of sound insulating panel.
At present, common sound insulation means of defence is a sound insulation by filling material in the middle of the interlayer body of wall in construction work, for example, China Patent No. is 92228723, the authorization notification number is 2148115 to disclose the utility model that name is called " steel bar concrete sandwich heat preservation sound insulating panel member ", architectural feature is to connect two-layer armored concrete slab face up and down with the light concrete web, and therebetween constitutes with light material.The certain deadening of sound insulating panel tool of this structure, but sound-absorbing effect is bad, and the structure heaviness, the scope of application is limited to.
The purpose of this utility model provides a kind of sound insulation, sound-absorbing effect is good, and structure is light and handy, uses wide sound insulating panel.
A kind of sound insulating panel of the utility model is bonded by the intermediate layer and the bottom of top layer, lightweight sound insulation material, and the top layer is provided with cellular through hole, and bottom is provided with cellular blind hole.Polyurethane foaming body can be adopted in the intermediate layer, and the moulding plastics plate of hollow can be adopted in the top layer, and the blind hole on the bottom can be the blind hole that plastic board forms after the hot pressing punching stretches.
The utility model has the advantages that: according to the attenuation principle of sound wave, the noise waves of high-decibel is by behind the cellular sheet surface layer, be dispersed into the acoustic wave source of numerous low decibel, the acoustic wave source of this low decibel is damped and absorption by the lightweight sound insulation material in intermediate layer, sound wave is further reduced, and the bottom plate then plays shielding action to sound wave.Because top layer and bottom can adopt plastic plate, polyurethane foaming body can be adopted in the intermediate layer, and therefore, structure is light and handy, has enlarged the scope of application.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the front view of the utility model sound insulating panel;
Fig. 2 is a sound insulating panel vertical view shown in Figure 1;
Fig. 3 is a sound insulating panel upward view shown in Figure 1.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model sound insulating panel 1 is bonded successively by top layer 2, intermediate layer 3 and bottom 4, top layer 2 is a two layers of plastic up and down, cellular through hole 5 is set, and leave gap 6 up and down between the two layers of plastic, the hole wall of through hole 5 plays to connect and supports the effect of plastic plate up and down, and the intermediate layer is that many microvoid polyurethane foaming bodies are arranged, bottom 4 is provided with cellular blind hole 7, and bottom 4 is that plastic board forms blind hole 7 after the hot pressing punching stretches.
Claims (4)
1, a kind of sound insulating panel is bonded by the intermediate layer and the bottom of top layer, lightweight sound insulation material, it is characterized in that the top layer is provided with cellular through hole, and bottom is provided with cellular blind hole.
2, sound insulating panel as claimed in claim 1 is characterized in that described intermediate layer is a polyurethane foaming body.
3, sound insulating panel as claimed in claim 1 or 2 is characterized in that described top layer is the moulding plastics plate of hollow.
4, sound insulating panel as claimed in claim 1 or 2, the blind hole that it is characterized in that described bottom are the blind hole that plastic board forms after the hot pressing punching stretches.
