A highway sound barrier system that uses a plurality of foam panels that are joined with an upright member assembly. The foam panels use a foam core and exterior weather protection compounds allowing the system to dramatically reduce transportation, handling and installation costs while increasing the lifecycle of the barrier system and reducing long term maintenance requirements. Moreover, the foam panels include rotatable joints and cable reinforcement allowing the wall to be easily adjusted to facilitate various landscape parameters and provide for rapid construction.

This invention is concerning a structure body containing inorganic particles having an average particle diameter of 6 mm to 50 mm, and 6 parts by mass to 40 parts by mass of a resin with respect to 100 parts by mass of the inorganic particles.

The present invention corresponds to a device for deflecting and decelerating a flow comprising a deflecting surface, a support structure connected behind the deflecting surface and a vortex generator connected on the deflecting surface, where the vortex generator generates two turbulent flow zones, a first low pressure zone below the vortex generator and a second high pressure zone above the vortex generator, and where the deflecting surface is concave in the direction of the incident flow, and the vortex generator is on the concave part.

The invention relates to a sound-absorbing construction component, which is suitable inter alia for use outdoors. The construction element comprises a sound-absorbing absorber layer having a sound entry surface and a plurality of extinguishing profiles fully enclosed in the absorber layer and arranged at a distance from one another. The extinguishing profile consists of a sound-reflecting material and has a profile inner space, which has one open side facing away from the sound entry surface. The extinguishing profile preferably comprises at least one inlet surface having numerous sound inlet openings and at least one closed reflection surface connecting to the inlet surface, wherein the reflection surface and the open side of the extinguishing profile are at a greater distance from the sound entry surface than the inlet surface. The profile inner space is hollow or completely or partially filled with the material of the absorber layer. The invention also relates to a sound protection wall having a backing layer on which numerous sound-absorbing construction components are arranged.

A barrier wall is formed by rotating a mold to a horizontal orientation so that a rear wall of the mold is horizontally disposed and an encircling sidewall upstands from the rear wall, the floor and encircling sidewall at least partially bounding a compartment, an upper end of the encircling sidewall at least partially bounding a first access opening to the compartment. A first material is disposed into the compartment through the first access opening, at least a portion of the material being curable. A cover is placed over the first access opening to enclose the compartment. The mold is then rotated from the horizontal orientation to a vertical orientation. A portion of the sidewall is then moved to form a second access opening to the compartment. A second material is then dispensed into the compartment, at least a portion of the second material being curable.

A barrier wall has a first vertical support and a second vertical support. A first wall panel is disposed between the first vertical support and second vertical support. A second wall panel is disposed between the first vertical support and second vertical support over the first wall panel. An I-beam is disposed between the first wall panel and second wall panel. The I-beam includes a first flange and second flange extending into the first wall panel and second wall panel. A cable is disposed between the first wall panel and second wall panel. The I-beam includes a ridge around the cable. A grounding cable is attached to the I-beam. The first wall panel includes a first channel extending for a length of the first wall panel. A first sound absorbing material strip is disposed in the first channel. A traffic barrier is disposed under the first wall panel.

A second wall panel is disposed between the first vertical support and second vertical support over the first wall panel. An I-beam is disposed between the first wall panel and second wall panel. The I-beam includes a first flange and second flange extending into the first wall panel and second wall panel. A cable is disposed between the first wall panel and second wall panel and attached to the first vertical support.

A wall panel has a block of base material, e.g., expanded polystyrene. A resonator tube is disposed in the block. A sound dampening material is disposed in the resonator tube. The sound dampening material can be recycled mattress or carpet. An inlet pipe extends into the resonator tube. A vent is disposed over the inlet pipe. A barrier wall can be formed by stacking multiple wall panels. Additional resonator tubes can be disposed between the wall panels.
