Plastic wall panel

摘要

Embodiments relate generally to plastic wall panels. Wall panels are formed by rotational molding processes and may be used in sound attenuation barriers or other wall or building structures. Some embodiments include reinforcing structure. The reinforcing structure may be configured to effectively support a plastic shell of the wall panel in a way that allows some relative movement between the plastic shell and the reinforcing structure.

主权项

1. A rotational-molded plastic sound attenuation barrier panel, the panel having walls defining an internal cavity and comprising reinforcing structure disposed in the cavity wherein the walls include front and back walls, wherein the panel further defines at least one aperture in the back wall of the panel to allow communication of an attachment mechanism through the respective aperture for coupling the reinforcement component to a support structure, and wherein a thickness of the front and back walls and a gap between the front and back walls are configured to attenuate sound through the panel by at least about 25 decibels at frequencies between 250 Hz and 5000 Hz.
