China Furniture Knowledge Series: Four Methods of Furniture Connection

Furniture is made up of several parts and components assembled in some way. Whether the connection method is correct or not directly affects the beauty, strength and processing technology of furniture. The commonly used connection methods of furniture are tenon joint, nail-wood screw connection, adhesive connection and connector connection.

1, tenon joint

Mortise-tenon connection refers to the connection mode that tenons are inserted into mortises or mortises, which is the basic combination mode of China classical furniture and modern furniture, and also the main combination mode of modern frame furniture.

According to different classification methods, tenors can be divided into different types:

According to the shape of tenon, it can be divided into right-angle tenon, dovetail joint, round bar tenon and round tenon; According to the number of tenons, it can be divided into single tenon, double tenon and multiple tenons;

Single tenon can be divided into single shoulder tenon, double shoulder tenon and multi-shoulder tenon according to the number of tenons;

According to the tenon-mortise connection mode, it can be divided into open tenon, closed tenon, semi-closed tenon, through tenon and non-through tenon;

According to whether the tenon end leaks, it can be divided into open tenon and hidden tenon;

According to the relationship between tenon and square wood itself, it can be divided into integral tenon and mortise.

There are many tenon-mortise structures of Chinese furniture, and all the furniture in wooden houses adopt the tenon-mortise connection mode, which continues this feature of Chinese furniture, with high connection strength, good stability, durability and beautiful appearance.

2. Adhesion and adhesion

Adhesive bonding refers to a way to connect the parts of wood products with adhesive. In actual production, bonding often plays an auxiliary role in other bonding methods. Different kinds of adhesives have different bonding properties, so they should be selected reasonably according to different process requirements. Mostly used in panel furniture.

3, nail and wood screw connection

Nailing is a simple connection method, with simple combination process and high production efficiency. Wood nails and bamboo nails are widely used in traditional carpentry in China. At present, metal nails are mainly used, including round steel nails, riding nails, T-shaped air nails and wood screws. Mostly used in panel furniture.

4. Connector joint

Connector connection is a way to assemble furniture parts into parts or products by using special connectors. This combination can be disassembled many times, and it can be adjusted directly if it is loose. Mostly used in panel furniture.
