Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is cementing cell schematics of the invention.
Specific embodiment
As shown in Figure 1, the present invention provides a kind of cross-bedding building blocks 1 welded based on ultrasonic wave lignin without gelatinization, by upper
Under the transversely arranged layer 2 that is successively stacked alternately and longitudinal arrangement layer 3 form.Wherein, transversely arranged layer 2 is by a plurality of in laterally arrangement
The timber of (as shown in figure 1 shown in horizontal direction) forms, and longitudinal arrangement layer 3 is by a plurality of in longitudinal arrangement (perpendicular with laterally arrangement)
Timber composition.
According to actual needs, the size dimension of transversely arranged layer 2 and longitudinal arrangement layer 3, that is, component units timber quantity can
To be adjusted correspondingly, every is orthogonal pass in the timber of longitudinal arrangement with every in the timber laterally arranged between each other
System.Particularly, it is not bonded by adhesive between transversely arranged layer 2 and longitudinal arrangement layer 3, by based on ultrasound
