Description

Technical Field

[0001] The utility model relates to the technical field of steel structure frame connection nodes, in particular to a bolt connection node of a steel structure frame. Background Art

[0002] Steel structure frame connection nodes refer to the connections between steel structures in building structures (mostly referring to the connections between beams and columns). This connection plays a vital role in the overall stability, bearing capacity and seismic performance of the structure. The design of steel structure frame connection nodes needs to consider many factors, including the type of material, the reliability of the connection method, the feasibility of construction, etc., to ensure the safety and durability of the building.

[0003] At present, the existing steel structure frame connection node, such as the Chinese patent with publication number CN116044040A, discloses an assembled energy-absorbing and shock-absorbing beam-column connection node, including a square steel column and an I-beam, the square steel column and the I-beam are connected by an L-shaped memory alloy connection plate through high-strength bolts; the L-shaped memory alloy connection plate includes an energy-absorbing and shock-absorbing connection component, a limit block and a bolt hole, the energy-absorbing and shock-absorbing connection component includes a hemispherical pad and a mini metal energy-absorbing rod, the hemispherical pad can reduce the end secondary bending moment of the mini metal energy-absorbing rod, making its stress state closer to uniaxial stress; the L-shaped memory alloy connection plate includes an energy-absorbing and shock-absorbing connection component, a limit block and a bolt hole, and the energy-absorbing and shock-absorbing connection component includes a hemispherical pad and a mini metal energy-absorbing rod. The hemispherical pad can reduce the end secondary bending moment of the mini metal energy-absorbing rod, making its stress state closer to uniaxial stress; The connecting plate is made of memory alloy, which can absorb seismic energy and recover quickly after earthquake by utilizing the material properties, and form a force transmission system with the energy-absorbing and shock-absorbing connection components. During a strong earthquake, the excess seismic energy is transmitted to the mini metal energy-absorbing rod through the hemispherical pad. The mini metal energy-absorbing rod undergoes plastic deformation and absorbs and dissipates the seismic energy together with the L-shaped memory alloy connecting plate. The upper and lower flanges of the beam are connected with L-shaped memory alloy connecting plates, which can prevent fatigue damage during unilateral connection and increase the fatigue strength of the beam-column connection node. However, the stability of the above structure is poor, and the connection takes a long time, which makes it inconvenient to install in practice.
