The columns of sound protection walls HPS 2 - 4.1 are iron-concrete elements shaped H. They are fixated in the axis distance 4.1 m and serve as bearing elements for setting sound protection panels up to height 3.9 m above ground.
Poles PHS 2 – 4.1 - 30 degrees are intended for making folds PHS 2x15 degrees and can be used up to height 3.3m above ground.
Poles PHS 2 – 4.1 - 60 degrees are intended for making folds PHS 2x30 degrees and can be used to height up 3.6m above ground.
Poles PHS 2 - 4.1 90 degrees are intended for making folds PHS 2x 45 degrees and can be used for heights up to 3.3 m above ground.
They are designed statically and evaluated as per ČSN EN 14388 Equipment for the reduction of road traffic noise - Specification, ČSN EN 1991 Euro-code 1: Structures load, ČSN EN 1992-1-1 Euro-code 2: Design of concrete structures, ČSN EN 1991-2-4 Euro-code 1: Principles of structures design and load - Part 2-4: Structures load - Wind load. They can be used at all PHS constructions except for the railways constructions for which other poles are intended.
