Embodiment Construction

[0045] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention:

[0046] as attached figure 1 As shown, the board body 1 of the sound insulation board is provided with cavities 2 at intervals, and sound-absorbing materials or sound-insulating materials can be filled in the cavities 2. The sound-absorbing materials include glass wool, polyester fiber cotton sound-proof cotton, centrifugal glass wool, rock wool, One of mineral wool and plant fiber or a mixture thereof, and the sound insulation material includes one or a combination of steel plates, lead plates, and brick walls; to improve the noise reduction effect; there is a micro Hole 4, to enhance the sound permeability so that it can be fully absorbed by the sound-absorbing material in the cavity; the bottom layer of the board body is provided with a reinforced steel mesh board 3, and the upper layer is provided with a steel wire mesh 5 to improve the overall strength...

Abstract

The invention discloses a sound insulation board. According to the sound insulation board, one side of the sound insulation board is provided with a perlite surface of which the surface is in a fluffy shape; a cavity is formed in the plate body at intervals; micropores are formed between the cavity and a bottom layer of the perlite layer; the other side of the sound insulation board is provided with a ceramsite cement solid surface; a reinforced steel bar mesh is arranged on the bottom layer of the plate body, and a steel wire mesh is arranged on an upper layer of the plate body; and a composite board is a one-step molding body. The sound insulation board has the advantages that the plate surface is in the fluffy shape, and sound waves can be absorbed and weakened; the composite board has an integral structure, and the plate body is solid, is wholly conveniently mounted and used and is difficult to damage; sound absorption or sound insulation materials can be filled in the cavity, and a noise reduction effect is improved; and moreover, the sound insulation board can be made of cement, perlite, ceramsite and other light-weight materials and is wide in material source and low in construction cost, and the materials and cost are saved.

Description

technical field [0001] The invention relates to a building board, in particular to a composite sound-insulating board with sound-insulating and sound-absorbing 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 the noise, it is necessary to set up some sound insulation panels to reduce the interference of traffic or construction noise on the lives of the surrounding residents. In recent years, the installation of sound insulation panels has also been mandatory in road design and construction. At present, many sound-absorbing panels are made of alloy plates and aluminum thin-plate packaged sound-absorbing materials. The sound-absorbing and sound-insulating effects are limited and ...
