LARGE-SPAN PREFABRICATED STRUCTURE

WIPO Patent Application WO/2023/123321

A1

Disclosed in the present invention is a large-span prefabricated structure. The large-span prefabricated structure, comprising a large-span prefabricated beam and multiple concrete filled steel tubular columns; the large-span prefabricated beam comprises multiple main beams and multiple secondary beams; the multiple main beams can be enclosed to form a large-span prefabricated beam frame, the multiple secondary beams are connected in the large-span prefabricated beam frame in a crossed manner, and the main beams and the secondary beams are all prestressed steel frame beam structures; and the multiple concrete filled steel tubular columns are used for being assembled and connected to multiple corners of the large-span prefabricated beam frame in an one-to-one correspondence manner. In the present solution, the large-span prefabricated beam is integrated and combined with the multiple concrete filled steel tubular columns, so that a large-span frame structure is conveniently provided, which thus helps solve the problems of limited span and low flexibility of building space use functions in the current construction industry.
