Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0033] like Figure 1~4 As shown, the environmentally friendly recycled concrete sound barrier panel of the present invention is composed of a sound insulation panel 2 and a sound absorption module 1 integrally casted on the sound insulation panel 2; the sound absorption module 1 is provided with several continuous regular protrusions structure, the cross-section of the raised structure is conical, and the cross-section of the raised structure can also be trapezoidal ( Figure 4 ), arc, rectangle.

[0034] like figure 2 , 3 As shown, the reinforced steel mesh 4 is set in the sound-absorbing module 1, the skeleton steel bar 3 is set in the sound-insulating panel 2, the connecting steel bar 5 is set in the sound-absorb...

Abstract

The invention discloses an environmental-friendly and multifunctional recycled concrete sound barrier panel, which comprises a sound insulation panel and a sound absorption module molded on the sound insulation panel by overall casting. The environmental-friendly and multifunctional recycled concrete sound barrier panel, the sound insulation panel and the sound absorption module of the invention are formed integrally, the bonding strength is high between two panels, at the same time, a connecting reinforcement bar is used for reinforcement, the overall strength is high, and the panel is solid and reliable, thereby effectively solving the fundamental problems of insufficient sound absorption performance and inadequate sound absorption panel strength for the traditional sound insulation panel. Moreover, the reclamation technology of construction wastes is fully used to apply recycled aggregates in a sound barrier panel. The replacement rate of construction wastes to natural aggregates can be more than 50 percent. Therefore, the invention has the advantages of resource saving and excellent performance.

Description

technical field [0001] The invention relates to the field of building functional materials, in particular to a concrete sound barrier board, and more specifically to an environment-friendly multifunctional recycled concrete sound barrier board for sound absorption and insulation of roads. Background technique [0002] Noise pollution is the fourth largest environmental pollution in the world after water pollution, air pollution and solid pollution. Traffic noise accounts for 85% of urban noise, so traffic noise is the most serious noise pollution. [0003] When sound waves pass through a medium or hit the surface of a medium, the process of reducing or converting sound energy into other energies is called sound absorption. The phenomenon that sound waves propagate in the air and air particles convert sound energy into heat energy due to vibration and friction, and the sound waves gradually attenuate with the increase of propagation distance is called air absorption; when so...
