"tenon and mortise" world cultural heritage

In recent hundreds of years, China has been regarded as "national quintessence" by overseas Chinese, one is the art of Peking Opera, and the other is solid wood furniture (tenon and mortise structure). Today, China traditional furniture culture has become a part of the world cultural heritage.

Mortise-tenon structure: Chinese ancient architecture is mainly made of wood structure, which is composed of columns, beams, purlins and other main components. The joints between structural members are matched by tenons and mortises to form an elastic wooden frame. Representative buildings: Forbidden City, Grand View Garden, Temple of Heaven, etc.

Mortise and tenon are a very ingenious invention. This connection mode of members makes the traditional wood structure in China a special flexible structure that surpasses the bent, frame or rigid frame of contemporary buildings. It can not only bear a large load, but also allow some deformation, which can offset some seismic energy under earthquake load and reduce the seismic response of the structure.

Mortise and tenon is a concave-convex connection method used on two wooden components. The protruding part is called tenon (or tenon); The recessed part is called mortise (or mortise, tenon groove), and the tenon and mortise mesh to play a connecting role. This is the main structural mode of wooden appliances such as architecture and furniture in ancient China. The tenon-mortise structure is the combination of tenon and tenon, which is a clever combination of more and less wood blocks, high and low, long and short, and can effectively limit the distortion of wood blocks in all directions. The most basic tenon-mortise structure consists of two parts, in which the tenon of one part is inserted into the mortise of the other part to connect and fix the two parts. The part where the tenon extends into the mortise is called tenon, and the rest is called tenon shoulder.

A home with tenon and mortise structure is more durable than a home with nail connection. This combination can effectively limit the distortion between wooden pieces in all directions. Many Ming and Qing style furniture are hundreds of years ago, but they are still as strong as ever. This is the practical experience of this structural combination.

Why did the tatami of Hehefu choose to be a mortise and tenon platform?

Inheritance of historical and cultural heritage.

The tenon-mortise structure is a combination of tenon and mortise. Tenon and mortise platforms are more durable and heavier than box platforms.

The mortise and tenon structure reduces the use of adhesive, thus reducing the release of formaldehyde, which is healthy and environmentally friendly.

The glue on the box platform is easy to weather, and the nails are easy to be corroded or rusted, so it cannot be stored for a long time.

The tenon-mortise structure platform is convenient for transportation, which is more convenient and labor-saving in the handling process.

Tenon and mortise structure platform is easy to maintain. If only one part is damaged, it can be replaced separately, but it is more difficult to maintain furniture assembled with nails.
