Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a beam-column node connection device for an assembled building structure. Background Art

[0002] Buildings often face earthquake shocks that exceed their design seismic intensity. Traditional frame node design follows the principle of ductility, mainly dissipating earthquake energy through the deformation of its components, but this process often produces significant residual deformation, which in turn increases the risk of structural system collapse in an earthquake. After an earthquake, whether it is repair or demolition and reconstruction, it will cause a long period of downtime and huge economic expenditure, resulting in considerable property losses.

[0003] In recent years, the frame structure composed of steel tube concrete columns and steel beams has been widely used in high-rise, super-high-rise and large-span building projects due to its excellent bearing capacity, good ductility and efficient construction speed.

[0004] When buildings are subjected to earthquake loads or other dynamic loads from different angles, these traditional connection structures may not be able to fully exert their expected energy dissipation effects. The main reason is that the existing structures lack the flexibility of multi-angle load directions, which easily leads to the mismatch between the preset energy dissipation mechanism and the actual load direction, thereby reducing the overall energy absorption and dissipation efficiency, which not only affects the safety performance of the structure, but also may aggravate the degree of damage to the structure under extreme conditions and increase the risk of collapse. Especially in areas where earthquakes occur frequently, the beam-column node is a key part in the structural system, and its energy dissipation efficiency is directly related to the seismic resistance and post-earthquake recovery ability of the building. Based on this, it is necessary to study a beam-column node connection device for prefabricated building structures. Summary of the invention

When the existing beam-column connection node structure is implemented, the energy dissipation direction of the connection structure between the beams and columns is relatively single. When facing multi-angle loads, it is difficult to effectively dissipate energy, resulting in poor energy dissipation effect of the beam-column node. It is easy to cause the preset energy dissipation structure to be inconsistent with the actual load energy dissipation direction, making it difficult to effectively dissipate the load. Based on this, this embodiment provides a beam-column node connection device for an assembled building structure.
