The invention discloses a pure solid wood orthogonal laminated wood, and belongs to the field of orthogonal laminated wood, the pure solid wood orthogonal laminated wood comprises an orthogonal laminated wood formed by orthogonal assembly and gluing of parallel layers and transverse layers located between two adjacent parallel layers, the parallel layers are hard solid wood layers, and the density and thickness of each parallel layer are basically the same; the transverse layers are soft solid wood layers, and the density and the thickness of each transverse layer are basically the same. And the thickness of the transverse layer is greater than 50% of the sum of the thicknesses of the two adjacent parallel layers. The transverse layers are made of pure cork wood, the density of the pure cork wood is relatively small, the elasticity of the pure cork wood is relatively large, and the pure cork wood can better adapt to, buffer and coordinate phase variables of hardwood on the adjacent parallel layers, so that deformation of all the layers of the cross-laminated wood is mutually coordinated, and stress is kept balanced; and the problems of deformation, warping, cracking and the like caused by inconsistent deformation and unbalanced stress of each layer are avoided.
本发明公开了一种纯实木正交胶合木，属于正交胶合木领域，所述纯实木正交胶合木包括由平行层和位于相邻两平行层之间的横向层正交组坯并胶合而成正交胶合木，所述平行层为较硬实木层，且每层平行层的密度和厚度基本相同；所述横向层为较软实木层，每层横向层的密度和厚度也基本相同；所述横向层的厚度大于其相邻两层平行层的厚度之和的50％。本发明的横向层采用纯软木，其密度相对较小，弹性相对较大，能够更好的适应、缓冲及协调其相邻平行层上硬木的相变量，从而使正交胶合木各层形变相互协调且受力保持均衡，避免因其各层形变不协调、受力不均衡而引发的变形、翘曲、开裂等问题。
