Abstract
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.

A construction element comprising:
- at least two wooden structural boards arranged so that a face of the first board and a face of the second board are superimposed at a contact interface, the superimposed faces being at least partially provided with a set of grooved patterns at the contact interface, the patterns having at least substantially complementary forms and being arranged so as to form an obstacle to the sliding of the first board and of the second board with respect to one another along at least one axis, and
- at least one holding system arranged so as to hold said at least two boards against one another at the contact interface,
- wherein the grooved patterns of said superimposed faces are pre-pressed against one another, and wherein the holding system comprises at least one metal threaded-rod member at least partially passing through at least two of said wooden structural boards at the contact interface.
