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.
Claims15
A method for manufacturing a construction element comprising the following steps:
- superimposing a first structural board having a first set of grooved patterns on an upper face and a second structural board having a second set of grooved patterns on a lower face so that the first set of grooved patterns on the upper face of the first structural board and the second set of grooved patterns on the lower face of the second structural board are in contact with each other at a contact interface, wherein the second set of grooved patterns are at least substantially complementary with the first set of grooved patterns;
- before holding the first structural board and the second structural board together, putting the first structural board and the second structural board under pressure against each other with a pressure of at least 75 kPa such that the grooved patterns are at least partially warped;
- and
- holding the first structural board and the second structural board together by a holding system comprising at least one metal threaded-rod member at least partially passing through the first structural board and the second structural board at the contact interface 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.
