TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building, in particular to a prefabricated composite reinforced concrete dense rib sandwich panel row system. BACKGROUND

[0002] The row structure is a basic structure form of single-story factory building structure, and the row is composed of a roof truss (or a roof beam), a column and a foundation, and the column is used for hinged connection with the roof truss and rigid connection with the foundation.

[0003] With the development of modern industrial technology, prefabricated buildings gradually replace the existing ordinary building system with the advantages of fast construction speed, less restriction by weather conditions, and saving labor. The prefabricated factory building is composed of wall panels, and the wall panels need to form a row structure with beams.
