Description

A mortise-and-mortise steel-wood composite strong shaft joint structure connected by tension bolts

technical field

The utility model belongs to the technical field of connection of building structures, in particular to a mortise-and-mortise steel-wood combined strong shaft joint structure connected by a pair of tension bolts.

Background technique

With the advent of the era of construction industrialization, wood structures have begun to develop in a higher and wider direction, while traditional wood structure beam-column joints can no longer meet the requirements of modern buildings. The joints between modern wood structure buildings can be connected by bolts, etc. many forms. As a part of modern wood structure building, steel-wood structure combines steel and wood with different advantages, and the development of green materials not only makes up for the shortcomings of traditional materials, but also gives full play to the advantages of both, conforming to China's sustainable development development strategy.

Wood structures have been widely used in low-rise residential buildings, but for some contemporary buildings, especially those with large spaces, large spans or large building structures, if only wood is used, it will not meet the requirements of structural design, which is not conducive to engineering application. Therefore, combining wood and steel into a new combination will help solve this problem.

The steel-wood composite node is a new type of steel-wood composite structure node which is made of pre-processed steel columns, wood beams and steel sleeves connected by bolts. This form of combined node is convenient for construction and assembly, and steel columns, wooden beams, and steel sleeves can be processed in a prefabricated factory and then assembled on site. And after the earthquake, due to its modular assembly process, the post-earthquake repair work is also very simple and quick.

The traditional wood structure and the contemporary steel structure are integrated with each other, and the connection method of the modern wood structure uses some connection methods of the steel structure. You can try to fix it with a steel sleeve at the connection part, so as to meet the requirements of structural strength and stability. Using steel as the main metal material for connection not only solves the requirements of structural stress, but also meets the requirements of the current node simplicity and beauty.

Due to the light weight of wood, the overall structural acceleration will be smaller than that of concrete structures and steel structures. However, the material nonlinearity of wood makes the damage of wood structures difficult to predict. The mechanical properties of wood in all directions are far inferior to steel. When the member is connected to the steel column, the traditional bolt connection makes the wood part in contact with the bolt at the end node of the wood beam extremely prone to shear failure along the grain, while the steel belongs to the isotropic body, and has good plasticity and obvious. The yield point, the steel joint generally does not need to consider the problem of shear damage, and the welding method is not suitable for the wood beam-steel column joint. It is more fragile, and a single pure wood structure node cannot solve the application in higher-rise buildings.
