Title (EN) CONSTRUCTION ELEMENT WITH PRE-PRESSED BOARDS
(FR) ELÉMENT CONSTRUCTIF À LAMES PRÉALABLEMENT PRESSÉES
Abstract:
(EN) The present invention relates to a construction element (10) with superposed wooden structural boards (101, 111). The boards are provided with grooved patterns (R101A, R111B) at the contact interface (I101-111) between the boards in order to prevent the first board (101) and the second board (111) from sliding relative to each other along at least one axis. The construction element (10) further comprises a retention system (30) for retaining the boards (101, 111) against each other at the contact interface (I101-111). According to the present invention, the grooved patterns (R101A, R111B) are pre-pressed against each other and the retention system (30) comprises at least one metal threaded rod component (30.1, 30.2) at least partially passing through at least two of the wooden structural boards (101, 111) at the contact interface (I101-111).
(FR) La présente invention concerne un élément constructif (10) à lames structurelles en bois superposées (101, 111). Les lames sont pourvues de motifs rainurés (R101A, R111B) au niveau de l'interface de contact (I101-111) entre les lames afin de faire obstacle au glissement de la première lame (101) et de la deuxième lame (111) l'une par rapport à l'autre suivant au moins un axe. L'élément constructif (10) comprend en outre un système de maintien (30) pour maintenir les lames (101, 111) l'une contre l'autre au niveau de l'interface de contact (I101-111). Selon la présente invention, les motifs rainurés (R101A, R111B) sont préalablement pressés les uns contre les autres et le système de maintien (30) comprend au moins un organe à tige filetée métallique (30.1, 30.2) traversant au moins partiellement au moins deux des lames structurelles en bois (101, 111) au niveau de l'interface de contact (I101-111).
