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

摘要

The present invention relates to a laminated plate for a multiple bonding structure for a vertical membrane member, comprising: a step of milling smallwood, which is lumber, into four surfaces to have a predetermined cross-section size, drying the same to a predetermined water content, and manufacturing a plurality of pieces of square lumber having a constant length by performing plane finishing to remove contraction or distortion in drying; a step of manufacturing a multiple plate by side-joining the plurality of pieces of square lumber manufactured from the previous step; and a step of manufacturing a vertical membrane member by allowing laminates, obtained by laminating three or more odd veneer single plates so that the fiber direction of a plurality of veneer single plates can cross each other, to be joined to upper and lower parts of the multiple plate as a surface layer and a rear layer, wherein the square lumber arranged in one side of the multiple plate is jointed to protrude from the surface and rear layers, and the square lumber arranged in the other side of an opposite multiple plate is joined to be concave than the surface and rear layers. The present invention can prevent strength reduction.
