Example Embodiment

[0035] The following specific examples further illustrate the present invention. The solution of the present invention is: the board includes three layers:

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

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

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

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

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

[0041] The board of the invention can be made of lightweight materials such as cement, perlite, ceramsite, etc., has low man...

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,...
