Description

Technical Field

[0001] The utility model relates to the technical field of fixing steel structure columns, in particular to an explosion-proof and stable bottom installation kit for steel structure columns. Background Art

[0002] With the development of modern construction technology, steel structures have been widely used in various fields. Steel structures have the advantages of light weight, high strength, and short construction period, so they have broad application prospects in high-rise buildings, large-span space structures, bridges and other projects. However, when steel structures are impacted by explosions, they are prone to damage and collapse, which poses a great hidden danger to project safety. Therefore, explosion-proof and stable steel structure column bottom installation kits came into being, providing effective safety protection for steel structure projects.

[0003] The traditional method of installing the bottom of a steel column mainly uses a concrete foundation, and the steel column is connected to the foundation by pre-buried anchor bolts. Although this method can meet the stability requirements of the steel column to a certain extent, under the impact of the explosion, the concrete foundation is prone to cracking, causing the steel column to lose support, and then damage and collapse. In order to solve this problem, researchers began to explore a new method for installing the bottom of a steel column to achieve the goal of explosion-resistant stability. Utility Model Content

In actual work, when the outer frame is hit, the impact force is transmitted to the counterweight block through the outer frame, and as the counterweight block slides back and forth on the damping rod, the energy of the impact is consumed.
