Metalic Noise Barriers Panacor AC100

TECHNICAL DESCRIPTION OF PRODUCT

The Panacor AC100 noise barrier is a product specially designed to reduce the noise generated by road and rail traffic.

Its design criteria use the noise signature of road and rail traffic as a reference, subsequently adapting the barrier’s noise abatement properties to optimise its overall efficiency.

Likewise, the design seeks to optimise the panel’s mechanical performance by fitting it with two deep guiderails to improve its mechanical ability to withstand wind pressure.

OVERALL MEASUREMENTS:
Length: 2000 - 6000 mm
Height: 300-400-500 mm

BARRIER COMPOSITION

The noise barrier can be made of grade DX51D+Z200/275-NA galvanised steel plating in accordance with standard UNE EN 10142, or with AA 3105 H24 aluminium sheet, either of which has a powder coating finish, customised as required in any shade on the RAL colour chart.

The inside of the composite panel is made up of sound-absorbing mineral wool of various densities and thickness depending on the precise noise-abatement properties required.

Thus, panels comprise four metal parts. The inner face (directed at the noise source) has holes over 36% of the surface area to provide for noise absorption, while the outer face is a plain, reflective panel. Barrier panels are installed between vertically arranged HEB/HEA profiles to achieve the desired overall height, in 300, 400 or 500 mm modules, and the distance between posts can be varied.

STRUCTURAL COMPONENTS

The barrier support structure is made up of HEA/HEB metal profiles with a welded baseplate, both grade S275JR according to standard EN 10025. Baseplates and profiles are galvanised and powder coated in accordance with the requirements of standards EN 1461 and EN 15773.

The profile posts are anchored to the foundations by means of anchor bolts of varying diameters, lengths and grades depending on the specific requirements of each individual project.

BARRIER ASSEMBLY

The barrier panel is designed to be mounted without any need for rivets or bolts and thus can easily be installed manually by two people without any need for electricity.

This rivet- and bolt-free solution is highly suited to situations where fatigue problems may appear, for example in hi-speed railway construction projects.

SURFACE FINISH

The thermosetting polyester powder coating process to which PANACOR AC100 acoustic fence panels are subjected produces excellent resistance to the effects of adverse weather, heat or continued exposure to sunlight, by providing enhanced corrosion-resistance and thus a product that requires practically no maintenance.

STAGE 1

PRE-TREATMENT

Automatic process to prepare panels for electrostatic application of paint powder.

Dip 1
Tank capacity: 5600 l
Dip temperature: 35 to 45ºC
Composition of dip liquid: De-greasing agent; passivator; water;
Daily monitoring of concentration levels in pre-treatment dip tank 1 according to specific procedure.

Dip 2
Tank capacity: 2300 l
Dip temperature: room temp.
Composition of dip liquid: water

Dip 3
Tank capacity: 2300 l
Dip temperature: room temp.
Composition of dip liquid: water

STAGE 2

DRYING

All metal parts are placed in a blow drying tunnel at a temperature of between 80 and 100ºC to eliminate any moisture prior to the subsequent spray coating stage.

STAGE 3

PAINT BOOTH

Automatic process using robots and touch-up guns with spray nozzles that guarantee a perfectly smooth, uniform coat is applied to the panels to ensure an excellent finish.

STAGE 4

POLYMERIZING OVEN

Process in which the paint finish is achieved by applying heat for at least 10 minutes at an average temperature of 200 ºC Oven temperature: 165 to 230ºC.
