Description

Technical Field

[0001] The invention relates to the technical field of anti-collision of building columns, and in particular to an impact-resistant and earthquake-resistant assembled column with a protective device. Background Art

[0002] In the context of new industrialization, buildings and bridges that adopt prefabricated assembly construction methods have been vigorously developed and promoted. Prefabricated engineering structures need to withstand many loads during their service life, and earthquake action is one of the main loads to be considered. The impact loads that buildings in different site environments may suffer are also different. For example, mountain engineering structures, including buildings and bridges, are impacted by falling rocks, rolling stones, and mudslides, roadside buildings and bridges are hit by vehicles, and urban buildings are hit by indoor natural gas explosions. In particular, it is easy to cause secondary disasters such as mudslides after an earthquake in a mountainous environment, causing earthquake-damaged engineering structures to suffer impact loads. In the context of the rapid development of prefabricated buildings, many important buildings and bridges, when the prefabricated frame columns and bridge piers, which are important load-bearing components, are subjected to sudden impact loads, they will face the risk of structural collapse after the failure of the components, which poses a great safety hazard. Therefore, it is particularly important to install protective devices on building columns and bridge piers.

[0003] Not only buildings and bridges need impact-resistant protective devices, but also onshore and offshore wind turbine columns and offshore platforms. Onshore wind turbine columns are subject to wind loads, earthquake shocks, and foreign object impacts, offshore wind turbine columns are subject to sea ice impacts, ship collisions, wind load impacts, earthquake shocks, and impacts of marine biological attachments, and offshore platforms are subject to sea ice, ship, and earthquake impacts. Onshore and offshore wind turbine columns and offshore platforms can use assembled columns. After these columns are prefabricated in the factory, they are transported to the site by large transport vehicles and quickly installed using cranes. The connection parts are specially designed to ensure the integrity and stability of the structure, and are also more convenient in later maintenance.

[0004] Protective devices have begun to be used on bridges and wind turbine columns. A Chinese patent (publication number CN118911082A) discloses an anti-collision device for a water bridge pier, including multiple groups of anti-collision units, which are sleeved on the pier and protect the pier, and the multiple groups of anti-collision units are arranged vertically; the anti-collision unit includes a support sleeve sleeved on the pier, and multiple support plates are rotatably arranged on the outer wall of the support sleeve, and each support plate is rotatably provided with an anti-collision plate, and a synchronization structure and a buffer structure are provided on the support sleeve, and the synchronization structure is used to make multiple support plates move synchronously, and the buffer structure is used to buffer multiple support plates. The existing protective device is an annular structure and is sleeved on the outside of the bridge pier as a whole. It adopts a mechanical structure to achieve buffering and anti-collision, and has a poor energy absorption effect. It is difficult to achieve the buffering purpose in the event of a mechanical failure, which is easy to cause damage to the pier, and the manufacturing cost is high. In addition, the protective device needs to be replaced as a whole after being damaged by impact, which has the defects of high replacement cost, difficulty in disassembly and installation, and inability to achieve rapid replacement. Therefore, the prior art needs to be further improved. Summary of the invention
