Connecting structure and construction method of fabricated shear wall structure

Abstract

The invention discloses a connecting structure and a construction method of a fabricated shear wall structure. The connecting structure comprises a prefabricated shear wall, steel structure connectingparts, a horizontal connecting unit and vertical connecting units, wherein a notch is reserved at the top of the lower-layer prefabricated shear wall, the horizontal connecting unit is arranged in the notch in a poured mode, vertical anchor ribs are reserved at the bottom of the upper-layer prefabricated shear wall, the vertical anchor ribs are inserted into and anchored in the horizontal connecting unit, horizontal connecting ribs are reserved at the ends of the two sides of the lower-layer prefabricated shear wall and the upper-layer prefabricated shear wall correspondingly, the steel structure connecting parts are installed at the ends of the two sides of the lower-layer prefabricated shear wall and the upper-layer prefabricated shear wall, the horizontal connecting ribs are anchored with the steel structure connecting parts, the steel structure connecting parts define vertical pouring spaces at the ends of the two sides of the lower-layer prefabricated shear wall and the upper-layer prefabricated shear wall, and the vertical connecting units are poured in the vertical pouring spaces. According to the connecting structure, the cast-in-place or grouting mode is adopted in the connection of the prefabricated shear wall, so that the problem that steel bars cannot be aligned is solved, the alignment difficulty between the steel bars and a sleeve during field hoisting of the prefabricated shear wall is greatly reduced, and the reliability and the construction speed of the connection position are improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated structures of building structures, in particular to a connection structure and a construction method of a prefabricated shear wall structure. Background technique [0002] The prefabricated concrete structure is a concrete structure that is assembled and connected by prefabricated components as the main force-bearing components. Prefabricated reinforced concrete structure is one of the important directions for the development of my country's building structure. It is conducive to the development of my country's building industrialization, improving production efficiency, saving energy, and developing green and environmentally friendly buildings. Compared with the cast-in-place construction method, the prefabricated PC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving,...

Problems solved by technology

The vertical connection methods of prefabricated walls mainly include grout anchor connection and grouting sleeve connection; prefabricated walls often have more steel bars and the diameter of the steel bars is small, making it difficult to align the wall with the grouting channel when hoisting on site , and it is prone to clogging and other phenomena during the grouting process, which affects the connection performance of the wall

The horizontal connection method of the prefabricated wall is mainly to reserve additional connecting steel bars at the edge of the wall, and pour the connecting area on site; the configuration of the steel bars at the connecting position is relatively dense, which makes the lifting of this connection process difficult, and the assembly process is complicated. The quality is difficult to control, causing great hidden dangers to the safety of the structure
