[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components supported by steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] There are still certain drawbacks in the use of energy-saving prefabricated steel structure buildings in the existing technology. The traditional assembly method mostly uses bolts or welding for the node positions. After long-term use, the welding gaps and bolt positions are prone to rust, reducing the firmness of the node connection. The node connection is also poor in flexibility and cannot be adjusted at will according to the direction of steel pipe installation. The firmness is poor, affecting the overall stability. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The invention designs two node connection methods with different structures, namely, the top node connector and the middle node connector, according to the different installation parts. The installation of the middle node connector needs to be positioned according to the reserved height of the limit bayonet. Four sets of limit bayonet need to be reserved at the required positions of the four faces before the steel frame leaves the factory. The middle node connector can be installed in the front, back, left and right directions according to the installation requirements through the four sets of limit bayonet, thereby increasing the flexibility of the node connection. The middle node connector is mainly used to connect the steel pipes inside the structure, while the top node connector is mainly used to connect the steel beams. The node is designed according to the connection part, which increases the convenience of assembly, saves more effort during assembly, and the node connection is more firm, making the whole more stable and reliable.

[0015] 2. The traditional method of welding wastes resources and pollutes the environment. The present application adopts connectors for connection, which is convenient for assembly and disassembly. The steel can be recycled later. There is less pollution to the environment during construction and dismantling, and it is more energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS
