Description

A kind of mortise and tenon wood truss for antique building

technical field

The utility model relates to the field of wooden structure roof components, in particular to a tenon-and-mortise wood truss for antique buildings.

Background technique

As the concept of environmental protection and energy saving is deeply rooted in the hearts of the people, wood structure buildings have attracted more and more attention. They are beautiful and comfortable, thermal insulation, excellent seismic performance, and flexible space layout. Compared with other building materials, wood structures have many technical and economic advantages, which mainly include: the reserves of wood resources are extremely abundant in my country, and the materials are simple and easy to obtain; industrialized production can be realized, production efficiency can be improved, and the quality of components can be guaranteed. Good rigidity; light weight of components, easy transportation, loading and unloading and on-site installation, saving costs; low energy consumption in the production process, saving energy; can be processed into structural components of various shapes and sizes according to needs. The development of wood structure buildings is in line with the country's deployment of vigorously developing green prefabricated buildings, and has great potential value.

Although wood resources are extremely abundant in my country, there are very few wood structures in China at present, which are not common or completely invisible in daily life. Therefore, it is extremely important to promote the development of wooden structures in my country and enhance the public's understanding of wooden structures.

With the improvement of people's living standards, the requirements for the construction of spiritual culture continue to increase, and more and more people focus on the traditional culture of our country. As an important part of Chinese culture, ancient wooden buildings in our country are also deeply loved by the public, so antique buildings are emerging in our country. As an important part of ancient wooden buildings in my country, the roof has great charm, and the lifting frame is one of its characteristics. The rafters of ancient buildings are not a straight piece of wood, but are divided into multiple wood sections, and the laying angles are not uniform, and there are certain changes. If it is still constructed according to the ancient method, it is time-consuming and laborious, and the accuracy is not high, and the fault tolerance rate is low, which will lead to an increase in the construction cost.

As an important roof load-bearing component of modern wood structures, wood trusses are varied and can be applied to buildings under various working conditions. Moreover, the wooden truss can perfectly meet the requirements of prefabricated buildings and green buildings. The construction period is short and the construction is simple. It can also be organically combined with antique buildings, perfectly unifying modern craftsmanship and primitive culture. It is the best choice for building roofs of antique buildings in my country.
