This material has a good sound absorption and sound insulation effect. Combined with a panel with a thickness of 9mm-18mm, this ceiling has a good sound absorption effect. Compared with the prior art, it has outstanding substantive features and significant progress.

Description

sound-absorbing ceiling

Technical field:

The utility model relates to the technical field of indoor and outdoor decorative building materials, in particular to a sound-absorbing ceiling, in particular to its mechanical connection structure.

Background technique:

Reference document, application number: ZL200420081596.4, applicant: Liu Ding'an, a "sound-absorbing ceiling" is disclosed in this case, which discloses a sound-absorbing ceiling, which includes a keel and a sound-absorbing panel, and is characterized in that the keel has two There are L-shaped side panels and a horizontal horizontal panel connected between the two L-shaped side panels. Several holes are arranged on the horizontal horizontal panel, and several holes are arranged on the sound-absorbing panel.

It can be seen from the structure of the existing disclosed sound-absorbing ceiling that the structure of the existing sound-absorbing ceiling is relatively simple, and there is no actual absorption effect, but only ordinary physical sound insulation, and the actual effect is not very obvious.

To sum up, it is still necessary to further improve the existing sound-absorbing ceiling structure so that it truly has the sound-absorbing function.

Invention content:

The purpose of this utility model is to provide a sound-absorbing ceiling, which is provided with a sound-absorbing non-woven fabric layer on the back of the board body. Disadvantages and deficiencies.

In order to achieve the above object, the technical solution of the present invention is: a sound-absorbing ceiling, which mainly includes a plate body, the surface of the plate body is evenly distributed with holes arranged in a matrix, and it is characterized in that: one surface of the plate body is provided with sound-absorbing Non-woven layer.

The utility model discloses a sound-absorbing ceiling, which is provided with a sound-absorbing non-woven fabric layer on the surface of the board body. This material has a good sound-absorbing and sound-insulating effect, and the board body with a thickness of 9mm-18mm makes the ceiling sound-absorbing. The effect is good, and compared with the prior art, it has outstanding substantive features and remarkable progress.
