Pearlite ceramsite composite acoustic board

Abstract

The invention relates to a pearlite ceramsite composite acoustic board, which is characterized in that pearlite is used as a surface course of an acoustic material, and ceramsite concrete is used as a base course; and by utilizing ambient pressure, two materials are connected into a whole through the bonding force of the concrete and snap-in force among nonuniform transitional surfaces. The product can be applied in paste surfaces of integral type acoustic barriers by utilizing a mounting hole and a mounting surface which are reserved on a light-weight monolithic composite acoustic board according to requirements of site operation and strip plate-type acoustic barriers with the length from 2 to 6 meters are formed by secondary cast-in-place and prefabrication, so that the acoustic barriers are fixed in structural members.

Description

technical field [0001] The invention relates to the technical field of noise pollution prevention and control, in particular to designing traffic noise control, in particular to a perlite ceramsite composite sound-absorbing board. Background technique [0002] At present, domestic perlite sound-absorbing panels are generally used for interior decoration. Generally, the products are small in size and thin in thickness. They generally have the characteristics of poor strength, waterproof, and poor durability, which cannot meet the outdoor use of traffic noise control. [0003] Domestic traffic noise control is generally achieved by setting up sound barriers. At present, there are many types of sound barriers, which can be divided into three categories: organic, inorganic and metal sound barriers according to their materials. The typical representative of inorganic sound barriers is glass fiber reinforced plastic sound barriers. Its disadvantages are that light resistance, agin...

AI Technical Summary

Problems solved by technology

The typical representative of inorganic sound barriers is glass fiber reinforced plastic sound barriers. Its disadvantages are that light resistance, aging resistance and fineness are not suitable for control, and the cost is high; the typical product of metal sound barriers is aluminum alloy sound barriers. It has many advantages such as beautiful appearance and anti-corrosion. Strong performance, easy to transport and install; but the cost is the highest, the vibration frequency is close to the vehicle vibration frequency, the deformation is large, the safety factor is low in the later stage, it cannot be done once and for all, and the later maintenance cost is high, so it is not convenient for large-scale promotion and use

For the above two materials, the inorganic material sound barrier has the advantages of low cost, low maintenance cost, good electrical insulation performance, and high structural safety. However, the general inorganic material is generally heavy, difficult to transport and construct, and has a low aesthetic level. There are some restrictions in the process of use and promotion
