Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a self-balancing frame supporting device for a steel structure lap column. Background Art

[0002] Lap column conversion is a novel conversion form that has emerged in recent years. When the building facade is retracted or the upper and lower floors are misaligned due to functional requirements, but the horizontal projection distance is small, the upper column of the conversion layer can be directly connected downward and the lower column can be directly connected upward, forming a column with a larger cross-sectional size on the conversion floor, which can complete the force transmission under vertical and horizontal loads together with the horizontal components (beams and plates) to achieve conversion. It can improve the overall stability and seismic performance of the structure, and has the characteristics of convenient construction, environmental protection and energy saving, and reduced material waste. Because steel structures have high plasticity and flexibility, steel structure lap column conversion can be applied to various complex architectural design requirements.

[0003] In structural design, this type of structure is mainly used in high-rise, super-high-rise, large-span spaces and complex building forms. In order to ensure the mechanical properties and usage functions of the structure during use, the transfer layer height of high-rise and super-high-rise buildings is usually higher than the standard layer. The increase in the transfer layer height can alleviate the rigidity mutation between the upper structure and the lower structure to a certain extent. Affected by the self-weight of the structure and the transfer area, during the structural conversion process, due to the increase in the self-weight of the structure and the transfer area, it is difficult to level the connection between the upper column and the structural beam during the installation process.

[0004] The traditional steel structure lap column conversion upper and lower column construction method requires the construction of a steel support frame, steel pipe frame support or steel support columns on the next layer of the conversion area for leveling. This method requires delaying the construction progress of the steel structure before the concrete structure, resulting in a significant increase in construction time and cost. Utility Model Content
