Why should solid wood furniture have expansion joints

Nowadays, many people like to put solid wood furniture in their homes, which is due to the fact that the texture of this furniture is particularly good-looking, and it will look special at home, but solid wood furniture will leave a telescopic space on the top when it is installed.

I can't stand it, what is called thermal expansion and contraction, wood and metal are different, the coefficient of thermal expansion and contraction is very small, and the reserved expansion joints are because the home has the characteristics of dry shrinkage and wet expansion, and moisture absorption will expand. Also, instead of suppressing the deformation and cracking of the wood, it leaves room for the deformation of the wood.

Prevent furniture from cracking, if it doesn't crack, it's not solid wood furniture! This is the characteristic of solid wood furniture. I am making furniture, very responsible to tell you, solid wood is not like the board, the board is to break the solid wood into powder or small particles, and then use a large amount of glue high temperature pressure into the board, to put it bluntly, maybe they break the solid wood is what kind of broken wood, and the wood has been broken, no vitality, solid wood is different, it is still a whole, there are a large number of invisible "cell cavity" in the wood, arranged in layers, no matter how good the drying technology, it is impossible to completely dry all the moisture in the cell cavity, Therefore, when the temperature and environment change, the cell cavity that is not dried will breathe like the pores of the skin, which is often called "thermal expansion and cold contraction", which is why solid wood furniture will leave that expansion joint, of course, the degree of cracking is also particular, if the cracking is too serious, it is not in place to dry.

Expansion joints, also known as shrinkage joints, are not caused by mistakes in furniture design and production, and play a huge role in curbing the physical characteristics of wood "thermal expansion and cold contraction" and improving the service life of solid wood furniture.

The expansion joint is to prevent the frame or corner tenon of the furniture from being cracked when the wood shrinks or expands due to the external environment, resulting in the loosening of the parts of the furniture and the inability to use normally.

The size of the expansion joint is very important, and the width of the expansion joint is determined by the specific gravity of the wood and the climatic characteristics of the region where the furniture is finally used, and the width is generally within centimeters.

You can go to the website of Tongyi Home and take a look. More detailed,

Leave a gap in order to better adapt to the environmental conditions of heat expansion and cold contraction!

1.The expansion joint is to prevent the frame or corner tenon of the furniture from being cracked when the wood shrinks or expands due to the external environment, resulting in the loosening of the parts of the furniture and the inability to use normally.

2.In order to reduce the deformation of the wood, there is a strict drying process before the wood is made into furniture, and some of them may have to be dried.

Hello question, this is a dining table, the back of the table is said to be an expansion joint, the merchant said, but the gap does not look beautiful, this gap is generally not visible after treatment, or just like that.

It's really not good-looking.

Question: This is how the back of the table I bought at home looks like this.

In the end, it's better to see it, or not to see it.

This expansion joint is pretty good.

Question: The above is very obvious, what you can see is good, but what you can't see is that there are no expansion joints? Or is it dealt with?

Solid wood furniture will shrink and expand with temperature changes, so it is better to keep this!

If it is done by a large manufacturer, it can be dried until there is no moisture in the wood, and there is no need to stay!
