Abstract:
1. A method of manufacturing a wooden beam comprising at least four elongated members connected by at least two crosspieces, said elongated members and said crosspieces being assembled to each other at assembly zones by gluing, the method comprising; arranging first and second elongated members parallel to one another and at a predetermined distance from one another; arranging the at least two crosspieces on the first and second elongated members; gluing, with a flexible glue, contact zones of the at least two crosspieces to contact zones of the first and second elongated members; arranging third and fourth elongated members respectively opposite the first and second elongated members and on the at least two crosspieces; gluing, with a flexible glue, contact zones of the at least two crosspieces and contact zones of the first and second elongated members to contact zones of the third and fourth elongated members, whereby the first elongated member, the second elongated member, the third elongated member, the fourth elongated member, and the at least two crosspieces form an assembly; and pressing the assembly in order to crush layers of the flexible glue to a predetermined thickness, wherein elastic joints are formed in each assembly zone after the pressing and after the flexible glue is dry, and wherein the elastic joints allow for a relative movement between the first, second, third, and fourth elongated members and the at least two crosspieces.
