Suspended prefabricated shear wall semi-buried inner wall connecting structure and method

Abstract

The invention discloses a suspended prefabricated shear wall semi-buried inner wall connecting structure and a method, and belongs to the field of prefabricated concrete structures. The connecting structure is used for connecting an upper suspended wall body and a lower suspended wall body, wherein a force bearing rod is arranged in the lower bracket wall body, the force bearing rod is connected with the upper suspended wall body comprising a lifting frame through a bolt, and then a penetrating nut which is completely screwed into the lower bracket wall body is reversely screwed back to an extension steel bar of the upper suspended wall body to complete steel bar connection; and a prefabricated bottom plate is installed on a suspension plate at the bottom of the lifting frame, an upper-layer steel bar of a floor penetrates through a semi-buried connecting area to form a steel bar mesh together with a Chinese character "gong"-shaped steel bar fixing frame on the prefabricated bottom plate, concrete is poured, a fully-poured surface layer is formed, and wall body connection is completed. According to the connecting structure, the lifting frame is used for suspending a shear wall, thesteel bars are connected through threads, the structural elevation of the upper-layer wall body is reduced, and integral connection is formed, so that the construction quality of the prefabricated part connecting area can be effectively controlled, and meanwhile, the construction cost is reduced and the construction flow is simplified and facilitated.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete structures, in particular to a semi-buried inner wall connection structure of suspended prefabricated shear walls. Background technique [0002] The prefabricated concrete structure is the main structural form of my country's construction industrialization. The main construction process is to prefabricate the prefabricated components in the factory, and then complete the installation of the components at the construction site according to the predetermined connection method, and the installation sequence of the upper and lower structural components is Lower wall → prefabricated laminated slab → cast-in-place surface layer → upper wall (transformed into lower wall) → prefabricated laminated slab → cast-in-place surface layer →, the upper wall installation in the last step is mainly the connection of steel bars, using Grouting connection, commonly known as "black box operation", has the disadvant...

[0002] The prefabricated concrete structure is the main structural form of my country's construction industrialization. The main construction process is to prefabricate the prefabricated components in the factory, and then complete the installation of the components at the construction site according to the predetermined connection method, and the installation sequence of the upper and lower structural components is Lower wall → prefabricated laminated slab → cast-in-place surface layer → upper wall (transformed into lower wall) → prefabricated laminated slab → cast-in-place surface layer →, the upper wall installation in the last step is mainly the connection of steel bars, using Grouting connection, commonly known as "black box operation", has the disadvantage that it is difficult to control the amount of grouting construction, and it is affected by many factors, such as grouting material mix ratio, workers' technical level and operating space, etc.
