Pure solid wood cross-laminated wood

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cross-laminated wood, in particular to a pure solid wood cross-laminated wood. Background technique [0002] CLT (Cross-laminated lumber) is a new type of engineered wood product that originated in Europe in the 1990s. It is made of at least three layers of solid wood sawn timber orthogonally stacked and glued to form solid wood squares or sheets. It has the advantages of good bearing performance, shock resistance, sound insulation, fire prevention, heat preservation and low carbon environmental protection, and it is easier to realize factory modules. Prefabricated and assembled on site. CLT can be used as load-bearing elements in timber buildings, such as floor panels, wall panels and roof panels. Large pieces of CLT can be directly cut and used as building exterior walls, with fast construction and short construction period, and can even be used for civil and non-civilian buildings with more than 20 f...

Problems solved by technology

[0005] Aiming at the problems of deformation, warping and cracking in the existing cross-laminated wood, the present invention provides a pure solid cross-glued wood without deformation, warping and cracking. Layer softness and hardness and its thickness configuration, so that the deformation of the inner and outer layers of cross-glued wood is coordinated and the force is balanced, so as to solve the problems of deformation, warping, cracking and other problems existing in traditional cross-glued wood
