[0002] Multi-layer log composite splicing board, also known as spliced multi-layer board or multi-layer solid wood splicing board, is a board composed of multiple wood boards through splicing and bonding. This board is usually composed of multiple layers of boards, and the wood grain of each layer of board is perpendicular to the adjacent board layer to improve the overall strength and stability of the board.
[0003] In the existing technology, such as the document with publication number CN208870329U, a wooden board splicing structure is specifically disclosed. Although the device in the document can splice wooden boards, the wooden board connection lacks fixing parts, resulting in poor connection firmness and is more likely to fall off. Secondly, the connection method of grooving on the wooden board has a more complicated manufacturing process and requires high processing precision, which will increase production costs. For this reason, we propose a new multi-layer log combined splicing board. Utility Model Content
