If you are careful, you will find that all solid wood boards are spliced in multiple pieces in the width direction, and the length direction is a whole piece of wood. Why is that?
Width direction imposition: All solid wood boards used in furniture need to be cut from wide boards into narrow boards with a width of less than 7cm, and then put together the narrow boards.
This process will cause a lot of loss (loss of 5mm per saw, because the thickness of the saw blade is 5mm), the reason for this is: any whole board with a width greater than 7cm, the expansion rate will be much larger, resulting in deformation and cracking of furniture Increased risk.
The imposition process will reduce the internal stress of solid wood, increase stability and reduce the risk of deformation and cracking. Whole root in the length direction: Different from the width direction, the length direction of solid wood, that is, the direction along the wood grain, has a very low expansion and contraction rate, so no imposition is made.
2. Expansion joint process
I believe everyone has also noticed that most solid wood furniture will reserve some gaps. This is not for aesthetic needs, but to reserve a certain space for solid wood expansion, so that the structure will not be damaged during expansion, and the push and pull will not be stuck. .
3. Mortise and tenon technology
The mortise and tenon structure is a concave-convex joint method used on two connected components in solid wood furniture.
The protruding part is called tenon (or tenon); the concave part is called tenon (or tenon, tenon). This form has reached a very high level of craftsmanship in traditional Chinese furniture, and is also common in other wood, bamboo, and stone utensils.
The "mortise and tenon" method of connecting various parts of Chinese furniture is the main structural method of furniture modeling. Various mortise and tenon joints are made in different ways and have different application scopes, but they all have the function of "joint" in the physical structure of each piece of furniture.
