Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to an assembled steel structure node with an angle adjustment function. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Steel structures need to be connected with the help of structural nodes when in use. Structural nodes are one of the main elements of the building structure system. Generally speaking, the components are limited by the maximum size of production or transportation, so the components that connect two or more fixed bodies are called structural nodes. At the same time, due to the large selectivity of node types, special structural nodes are sometimes deliberately designed to increase structural toughness or reduce structural internal forces.

[0003] However, most of the existing connection methods are rigid connections. When rigidly connected, the forces between components can be decomposed into vertical force, horizontal force and bending moment, but steel structure components cannot be fine-tuned in angle. When encountering a turn, the steel parts can only be bent, which easily affects the internal structure of the steel body. Therefore, it does not meet the existing needs. In this regard, we propose an assembled steel structure node with angle adjustment function. Summary of the invention
