Multi-layer glued structural cross laminated timber panel for perpendicular diaphragm member， manufacturing method thereof and jointing method thereof

In the manufacturing method of the multi-junction structural aggregate plate for the vertical diaphragm member according to the present invention to make a small cross-section of the thin-necked wood to four sides to have a certain cross-sectional dimension and to dry to a predetermined moisture content， in order to remove the shrinkage or distortion during drying Manufacturing a plurality of right angle members having a predetermined length by finishing the planer， manufacturing the judges by side joining the prepared right angle members， and stacking a plurality of veneer end plates into three or more odd sheets so that the fiber directions cross each other. The plywood is bonded to the upper and lower parts of the judge， respectively， in the upper and lower layers， wherein the right angle member disposed on one side of the judge is protruded from the front and back layers， and the right angle member disposed on the other side of the opposite judge enters more concave than the front and rear layers. It characterized in that it comprises a step of manufacturing a vertical diaphragm member by bonding to.
