Wooden Lattice Girder for Construction
摘要:
The invention proposes a wooden lattice girder 1 for construction comprising an upper chord 4 and a lower chord 5, connected to each other by struts 2, having tenons 7 each at the ends thereof, wherein the tenons 7 at one end each of the struts 2 are glued into mortises 9 on the upper chord 4, running in the longitudinal direction of the upper chord 4, and the tenons 7 at the other end of the struts 2 are glued into mortises 9 on the lower chord 5, running in the longitudinal direction of the lower chord 5. The lateral surfaces 12 of a respective mortise 9 running in the longitudinal direction thereof encompass an acute angle and the surfaces 10 of the tenon 7 glued to said lateral surfaces 12 of said mortise 9 encompass a corresponding acute angle.
