Description

A steel structure housing unit

technical field

The utility model belongs to the technical field of building structures, in particular to a steel structure building unit.

Background technique

The architectural forms and styles of houses vary greatly, but in terms of structural system (supporting skeleton), there are only several main structural forms such as brick-concrete structure, wood structure, reinforced concrete structure and steel structure. As the country's awareness of environmental protection continues to deepen, wood and clay bricks have been restricted and used for a limited time. At this stage, the structural form of residential buildings in my country is mainly reinforced concrete frames, but the construction of this structure is cumbersome, and there is a lot of construction waste. The shortcomings of self-heavy, relatively small depth and bay, thick beams and columns, and low space utilization rate cannot meet the functional requirements of residential buildings with increasingly high conditions to a certain extent. Therefore, it becomes an important trend in the development of residential buildings and structures to develop a new type of residential structure system that is durable, rapid in construction, flexible in space layout, and easy to remodel.
