The wood structure building is a structure system in ancient buildings in China, is simple in material obtaining, convenient to construct and low in cost on the basis of ensuring strength. In the development of the existing wood substitute structure, the construction is simple and quick, the industrialization requirement is met, and the development stage of the prefabricated wood substitute structure is gradually transited.

Among four common building engineering materials, namely steel, wood, stone and concrete, wood is the only renewable natural resource. At present, China is vigorously promoting ecological civilization construction, and wood is used as a renewable material and can be efficiently utilized as an engineering material. The wood structure building is attractive and environment-friendly, short in construction period, capable of being prefabricated in a factory and installed on site, good in heat insulation performance, flexible in design form and capable of meeting the current situations of economy, high-speed construction and resource shortage in China.

The wood structure node is the key in the wood structure system, is closely related to the integrity, safety and stability of the whole structure, and the connection structure of the wood structure node is continuously updated along with the progress of the times. Wood structural members are generally composed of two parts, a wood member and a connector. Mainly comprises tenon-and-mortise joints, nails, bolts and other connection modes. At present, wood structures are connected in a plurality of ways, but series development and industrial production are lacked. In order to meet the requirements of the current industrialized buildings, the design of the nodes is standardized and unified, so that the large-scale production is facilitated, and the efficiency of the prefabricated assembly type is improved.

Detailed Description

In order to make the technical field person understand the solution of the present invention better, the technical solution of the present invention is further described below with reference to the specific embodiments.

Examples

Referring to fig. 1 to 2, two wood structure mortise and tenon structures for connection of wood structures themselves. In the figure, a first wood member 1 and a second wood member 2 are primarily connected through a tenon 3 and a mortise 4, the tenon 3 and the mortise 4 are equal in size, and the first wood member 1 and the second wood member 2 are vertically arranged to form a T-shaped structure.

In the second drawing, the third wood member 5 and the fourth wood member 6 are primarily connected through the first mortise 7 and the second mortise 8, the first mortise 7 and the second mortise 8 are equal in size and can be engaged together when they are in contact with each other, and the third wood member 5 and the fourth wood member 6 are vertically arranged to form a crisscross structure.
