1. Symmetry: The corresponding layers are distributed on both sides of the symmetrical center plane of the building template, that is, the tree species of the veneer; the thickness; the fiber direction and the number of layers; the manufacturing method and moisture content must be the same to avoid warping.
2. Odd-numbered floor: odd-numbered floor building formwork, its symmetry is called the center plane on the center plane of the central layer veneer. In this way, when the building formwork is bent, the central layer with the greatest shear stress only falls on the wood of the central layer, instead of acting on the glued layer. Ensure the strength of the building template.
3. Staggered texture: the fiber directions of adjacent layers of veneers that make up the building template are perpendicular to each other. Therefore, the transverse tensile strength of the building template is greatly improved. The tensile strength along the grain is lower than the tensile strength of the wood, so the tensile strength of the building template and the transverse grain direction tend to be the same, thus changing the anisotropy of the wood.
