Abstract

A kind of acoustic board of zigzag wave structure, with basic unit and corrugated layer, the basic unit is fixedly connected with corrugated layer or is mutually integrated, and the cross section of the corrugated layer is zigzag wave structure.It is mounted in when the utility model is used in gobo, when sound enters the acoustic board of zigzag wave structure through the gobo cover plate with sound penetrating hole, energy is absorbed by the acoustic board of zigzag wave structure, therefore can effectively improve acoustically effective；The utility model takes up space smaller when transporting.

Description

A kind of acoustic board of zigzag wave structure

Technical field

The utility model is related to a kind of acoustic board of zigzag wave structure.

Background technology

Today's society traffic technique is developed rapidly, and can produce many noises in actual traffic circulation, highway The noise problem produced with high ferro is just solved by the gobo laid in trackside, and the surface of the acoustic board of traditional gobo is put down Whole, the contact area with sound wave is small, acoustically effective be not it is fine, and surfacing acoustic board transport when take up space also compared with Greatly.

The content of the invention

The purpose of this utility model, which is to provide one kind, can effectively improve acoustically effective, and take up space less sawtooth during transport The acoustic board of shape wave structure.

To achieve these goals, the technical solution of the utility model is：A kind of acoustic board of zigzag wave structure, its Improvement is：With basic unit and corrugated layer, the basic unit is fixedly connected with corrugated layer or is mutually integrated, the corrugated layer it is cross-section Face is zigzag wave structure.

In the above-mentioned technical solutions, the material of the basic unit and corrugated layer is polyurethane.

In the above-mentioned technical solutions, the cross section of the zigzag wave structure of the corrugated layer has 5 ~ 12 crests.

In the above-mentioned technical solutions, the length of the acoustic board is 650 ~ 1960mm, and width is 430 ~ 880mm.

In the above-mentioned technical solutions, the height dimension H of the acoustic board is 50 ~ 120mm.

In the above-mentioned technical solutions, the ratio between height dimension H of the height dimension h of the corrugated layer and acoustic board be 30% to 50%.

In the above-mentioned technical solutions, the cross section of the zigzag wave structure of the corrugated layer has 8 ~ 9 crests.

In the above-mentioned technical solutions, the ratio between height dimension H of the height dimension h of the corrugated layer and acoustic board be 36% to 40%.

Benefit of the present utility model is：1), because there is acoustic board the cross section of corrugated layer and corrugated layer to be zigzag wave Unrestrained structure, in use, the acoustic board of zigzag wave structure is mounted in gobo, compared to the acoustic board of past surfacing, sheet The surface of utility model has the zigzag wave structure of out-of-flatness, under equal volume, and surface area can be than conventional increase very To several times；2）, the cross section due to acoustic board with corrugated layer and corrugated layer be zigzag wave structure, can be by one piece during transport The crest of the zigzag wave structure of acoustic board is embedded into the trough of the zigzag wave structure of another piece of adjacent acoustic board, because And it is smaller to be taken up space when transporting.

Embodiment

Below in conjunction with accompanying drawing and the embodiment provided, the utility model is further described.

As shown in Fig. 1 ~ 8, a kind of acoustic board of zigzag wave structure, with basic unit 1 and corrugated layer 2, the He of basic unit 1 Corrugated layer 2 is fixedly connected or is mutually integrated, and the cross section of the corrugated layer 2 is zigzag wave structure.

The material of the basic unit 1 and corrugated layer 2 is polyurethane.

The cross section of the zigzag wave structure of the corrugated layer 2 has 5 ~ 12 crests.

The length of the acoustic board is 650 ~ 1960mm, and width is 430 ~ 880mm.

The height dimension H of the acoustic board is 50 ~ 120mm.

The ratio between the height dimension h of the corrugated layer 2 and the height dimension H of acoustic board are 30% to 50%.

The cross section of the zigzag wave structure of the corrugated layer 2 has 8 ~ 9 crests.

The ratio between the height dimension h of the corrugated layer 2 and the height dimension H of acoustic board are 36% to 40%.

As shown in Fig. 9,10, it is mounted in when the utility model is used in gobo 3, sound passes through the gobo with sound penetrating hole When cover plate enters the acoustic board of zigzag wave structure, energy is absorbed by the acoustic board of zigzag wave structure, therefore can be effective Improve acoustically effective；The crest of the zigzag wave structure of one piece of acoustic board can be embedded into another piece of adjacent sound absorption during transport The trough of the zigzag wave structure of plate, thus it is smaller to be taken up space during transport.
