摘要： A construction element includes superposed wooden structural boards that are provided with grooved patterns at the contact interface between the boards in order to prevent the first board and the second board from sliding relative to each other along at least one axis. The construction element further includes a retention system for retaining the boards against each other at the contact interface. The grooved patterns are pre-pressed against each other and the retention system includes at least one metal threaded rod component at least partially passing through at least two of the wooden structural boards at the contact interface.
