Embodiment Construction

[0035] The following specific examples further illustrate the present invention, and the scheme of the present invention is: the plate comprises three layers:

[0036] One side is the bottom layer of ceramsite layer;

[0037] Cavities are arranged at intervals in the middle layer, and micropores are arranged between the cavities and the bottom layer of the perlite layer;

[0038] The other side is a solid cement surface, and the bottom layer of the board is equipped with a reinforced steel mesh board;

[0039] Further, the cavity of the board is filled with sound-absorbing materials, including one or a mixture of glass wool, polyester fiber cotton sound-insulating cotton, centrifugal glass wool, rock wool, mineral wool, and plant fibers;

[0040] Further, the sound-insulating material is filled in the cavity of the plate, including one of steel plate, lead plate, brick wall or a combination thereof.

[0041] The board of the invention can be made of light materials such as c...

Abstract

The invention discloses a plate. The plate comprises three layers; a ceramsite bottom layer is arranged on one side of the plate; a cavity is formed in a middle layer of the plate at intervals; micro pores are formed between the cavity and the ceramsite bottom layer; a cement solid surface is arranged on the other side of the plate; and a reinforcing steel bar screen plate is arranged on the bottom layer of the plate. The plate has the advantages that a plate surface is fluffy so that sound wave absorption can be weakened; a composite board has an integrated structure, is mounted integrally, and is convenient to use and not easy to damage; the cavity can be filled with sound-absorption or sound-insulation materials, and a noise reduction effect is improved; and a sound-insulation plate can be made of light materials such as cement, perlite and ceramsite, material sources are wide, the manufacturing cost is low, and the materials and the cost are saved.

Description

technical field [0001] The invention relates to a building board, in particular to a composite board with sound insulation and sound absorption functions. Background technique [0002] The noise generated by urban road traffic vehicles, the noise generated by construction and other noise pollution have a great impact on people's work and life, and even bring harm to people's health. For this reason, both sides of the road, especially viaducts, and around construction sites In order to block noise, some boards need to be installed to reduce the interference of traffic or construction noise on the lives of surrounding residents. In recent years, boards are also mandatory in road design and construction. At present, many plates are made of alloy plates and aluminum thin plates packaged with sound-absorbing materials. The sound-absorbing and sound-insulating effects are limited and the cost is relatively high; this kind of sound barrier lacks effective sound-absorbing functions,...
