Abstract

The invention relates to a prestressed hollow plate of bundling type filling boxes and a manufacturing method thereof, and belongs to the field of general building construction. Viewed from the cross-sectional view, the hollow plate comprises rib beams (1), a top flange (2), a bottom flange (3) and the bundling type filling boxes (4), wherein concrete (5) needs to be poured at the parts of the ribbeams, the top flange and the bottom flange. The prestressed hollow plate is characterized in that each group of bundling type filling boxes are formed by clinging at least two rows and at least twocolumns of filling boxes (6) in the plane, longitudinal reinforcing steel bars (7), prestressed ribs (8) and stirrups (9) are arranged in the rib beams, and at least two mutually perpendicular plate ribs (10) are arranged in each of the top flange and the bottom flange. The prestressed hollow plate of the bundling type filling boxes is particularly suitable for a large-span and large-load hollow floor system, has good economical efficiency and applicability, and promotes the development of the building technology.

Description

[0001] (1) Technical field [0002] The invention relates to a cast-in-situ concrete hollow floor structure, in particular to a prestressed hollow slab of a cluster filling box and a manufacturing method thereof, belonging to the field of general building construction. [0003] (2) Background technology [0004] In the field of construction, with the continuous development of the economy and the improvement of people's living standards, people's requirements for building quality are getting higher and higher, and structures with large spans and large loads continue to emerge. Although the steel structure is a good structural form, compared with the hollow floor, the steel structure has the disadvantages of high cost, high structural height, and relatively small structural rigidity. [0005] I have been engaged in the research and application of prestressing and hollow floor technology for a long time. Applying prestressing technology to hollow floor can manufacture cast-in-plac...
