Box-wall for acoustic insulation and constituent beams

Abstract

Abstract Translated from French L'INVENTION A POUR OBJET DES MURS-CAISSONS D'ISOLATION PHONIQUE ET LES POUTRES PREFABRIQUEES QUI SERVENT A LA CONSTRUCTION DE CES MURS. UN MUR-CAISSON SELON L'INVENTION EST COMPOSE DE CELLULES IDENTIQUES INDEPENDANTES ALIGNEES. CHAQUE CELLULE COMPORTE DEUX MURS TRANSVERSAUX 1, 2 DE FORME TRAPEZOIDALE ISOCELE QUI SONT COMPOSES DE POUTRES PREFABRIQUEES EN BETON ARME 8 DE FORME TRAPEZOIDALE QUI SONT SUPERPOSEES. CHAQUE CELLULE COMPORTE DEUX RANGEES DE DALLES DE PAREMENT 3, 4 QUI SONT COMPLETEMENT IMBRIQUEES ENTRE LES POUTRES ET QUI SONT INCLINEES VERS L'EXTERIEUR EN MONTANT. LES POUTRES ET LES DALLES SONT SYMETRIQUES PAR RAPPORT A UN PLAN MEDIAN LONGITUDINAL. LES CELLULES SONT REMPLIES DE REMBLAI COMPACTE QUI FORME DES TALUS ENTRE LES DALLES SUR LESQUELS ON PEUT FAIRE POUSSER DES PLANTES. UNE APPLICATION EST LA CONSTRUCTION DE MURS ANTI-BRUIT LE LONG DES VOIES BRUYANTES. THE OBJECT OF THE INVENTION IS SOUND INSULATION WALLS AND PREFABRICATED BEAMS WHICH ARE USED IN THE CONSTRUCTION OF THESE WALLS. A CASING WALL ACCORDING TO THE INVENTION CONSISTS OF IDENTICAL INDEPENDENT ALIGNED CELLS. EACH CELL INCLUDES TWO TRANSVERSE WALLS 1, 2 OF ISOLATED TRAPEZOIDAL SHAPE WHICH ARE COMPOSED OF PREFABRICATED BEAMS 8 OF TRAPEZOIDAL SHAPE WHICH ARE SUPERIMPOSED. EACH CELL INCLUDES TWO ROWS OF FACING SLABS 3, 4 WHICH ARE COMPLETELY IMBRICATED BETWEEN THE BEAMS AND WHICH ARE INCLINED OUTWARDS UPWARDS. BEAMS AND SLABS ARE SYMMETRICAL WITH RESPECT TO A LONGITUDINAL MEDIAN PLANE. THE CELLS ARE FILLED WITH COMPACT FILL WHICH FORM SLOPES BETWEEN THE SLABS ON WHICH PLANTS CAN GROW. ONE APPLICATION IS THE CONSTRUCTION OF NOISE WALLS ALONG NOISY TRACKS.
