Description

A kind of assembled steel structure capable of shock absorption

Technical Field

The utility model relates to the field of steel structure technology, in particular to a shock-absorbing assembled steel structure.

Background Art

Prefabricated buildings are buildings assembled on site from prefabricated parts and components. According to the form of prefabricated components and the construction method, they are divided into five types: block buildings, plate buildings, box-type buildings, skeleton plate buildings and rising-slab and rising-storey buildings. Among them, prefabricated steel structures are structures made mainly of steel and are one of the main types of prefabricated building structures. Steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability, so it is particularly suitable for building large-span, super-high and super-heavy buildings.

However, since steel structures have a certain vibration absorption effect, existing steel structures are mainly used to prevent buildings from being damaged by vibration waves during earthquakes. However, in some windy areas, some steel frame buildings, such as steel towers, advertising racks, columns, etc., may not only be affected by earthquake vibrations, but also by wind from different directions, making the connection points of their bases prone to breakage.
