Description
Technical Field
The utility model relates to a building steel structure, building engineering field specifically are an utilize channel-section steel to strengthen connection structure of steel pipe node.
Background
The structural member formed by the steel pipe has the advantages of excellent tensile, compression, bending and torsion resistance, lighter structural weight and steel saving, and the steel pipe structure is widely applied to structural forms of plane or space trusses, net racks, net shells and frames in recent years. For hollow and thin-walled steel pipes, the radial rigidity is far smaller than the axial rigidity, and the radial bearing capacity at the node is far smaller than the axial bearing capacity. The failure mode of the component is mostly shown as node buckling or weld cracking at the joint of the main pipe and the branch pipe, which leads to the failure of the whole structure. Therefore, in order to ensure the basic criteria of 'strong node and weak rod' of the steel structure, a novel steel pipe connecting structure which is convenient to construct, reasonable in structure and capable of improving node ductility is researched and developed.
Therefore, the connection structure for reinforcing the steel pipe joint by using the channel steel is provided by the technical personnel in the field, so as to solve the problems in the background.
