A whole-span prefabricated prestressed groove-shaped rib plate, floor structure and assembly method thereof

Abstract

The invention discloses a whole span pre-prefabricated prestressed groove-type rib plate, a floor cover structure and an assembly method thereof. The floor cover structure is composed of framework beams and prefabricated prestressed groove-type rib plates inside beam grillages. The whole span pre-prefabricated prestressed groove-type rib plate is used as a basic assembly unit for a floor cover, suitably wide gaps are formed between longitudinal ribs of laterally adjacent prefabricated groove-type rib plates and between the longitudinal ribs of groove-type rib plates and the adjacent frameworkbeams, and the gaps are filled with sealing materials; and interconnection is achieved by precompression of high-strength bolts vertically passing through the longitudinal ribs and the longitudinal ribs, and the longitudinal ribs and the adjacent framework beams. Transverse ribs of the rib plates are in pre-compressed connection with side faces of the adjacent framework beams by employing curved unbonded steel strands on the, and a gap of a certain width is left between the two, and the gap is filled with high-strength mortar. The whole span pre-prefabricated prestressed groove-type rib plate,the floor cover structure and the assembly method thereof solve the problem that connection joints are excessive, a prefabricated component side mold is complicated, the production efficiency is low,connection integrity is poor, and the like brought by a too small prefabricated component unit of an existing prefabricated floor cover structure, extension of ribs surrounding a prefabricated plate,superimposed pouring, non-prestressed connection, and the like,.

Description

technical field [0001] The invention relates to a whole-span prefabricated prestressed groove-shaped rib plate, a prestressed assembled groove-shaped rib plate floor structure and a prestressed assembly method thereof, which belong to the building assembly technology. Background technique [0002] In recent years, with the continuous improvement of people's requirements for living conditions and living environment, the construction industry has developed rapidly. However, the development of the construction industry has caused serious resource consumption and environmental pollution, forcing people to seek a new way out of the construction industry. At present, the industrialization of buildings characterized by prefabricated buildings is one of the key ways to achieve low-carbon and sustainable development in the construction industry. [0003] In prefabricated buildings, the connection of structural components has a crucial influence on the efficiency of prefabricated and...
