Abstract

The invention relates to a high-strength multilayer wooden structure material and a manufacturing method thereof. The high-strength multilayer wooden structure material is formed by sequentially arranging cross laminated timber (CLT) and oriented strand boards (OSBs) in a crossed way, bonding and splicing. The manufacturing method comprises the steps of (1) treating the oriented strand boards; (2) treating the cross laminated wood; (3) gluing; (4) stacking for assembling; (5) cold-pressing. The CLT-OSB- . . . -CLT sandwich type multilayer wooden structure material is formed by splicing the CLT and the OSBs under the bonding effect of environment-friendly wood adhesive; the manufactured wooden structure material is good in performance and high in strength.

Description

technical field

[0001] The invention relates to a high-strength multilayer wooden structural material and a manufacturing method thereof, belonging to the technical field of wood processing. Background technique

[0002] Oriented strand board OSB (Oriented Strand Board) and cross-laminated timber CLT (Cross Laminated Timber) as two structural materials have been increasingly recognized by consumers.

[0003] Studies have shown that due to the vertical and horizontal staggered orthogonal combination of CLT, the material has the same dry shrinkage and wet expansion characteristics in the vertical and horizontal directions, and the overall linear dry shrinkage and wet expansion coefficients are less than 0.05%, and its dimensions are stable. The durability is 12 times that of solid wood and glued wood. At the same time, CLT materials have excellent fire resistance, earthquake resistance and sound insulation properties, and they also have competitive advantages in terms of cost...
