Assembled annular rebar buckling anchoring-connection concrete shear wall unilateral floor slab connecting structure

Abstract

The invention discloses an assembled annular rebar buckling anchoring-connection concrete shear wall unilateral floor slab connecting structure which comprises an upper-layer outer wallboard, a lower-layer outer wallboard and a composite floor slab positioned on one side. Each of the upper-layer outer wallboard and the lower-layer outer wallboard is a prefabricated annular reinforced concrete structure, vertical annular rebars are prefabricated inside each prefabricated annular reinforced concrete structure in the vertical direction, upper and lower ends of the vertical annular rebars extend outside upper and lower ends of the outer wallboards, criss-cross annular rebars are prefabricated in the composite floor slab, and two ends of the annular rebars extend to the outer sides of corresponding two ends of the composite floor slab. During connection, the vertical annular rebars reserved at the lower end of the upper-layer outer wallboard and those reserved at the upper end of the lower-layer outer wallboard are mutually overlapped and then overlapped with the annular rebars reserved on one side of the composite floor slab to form a binding frame, longitudinal reinforcing rebars are bound at four corners of the binding frame, and integral pouring is performed to the upper end face of the composite floor slab to form the whole connecting structure.

Description

technical field [0001] The invention relates to a connection structure between a prefabricated shear wall and a floor slab, in particular to a connection structure of a single-side floor slab of a prefabricated ring bar fastening and anchoring concrete shear wall. Background technique [0002] Facing the rapid development of urbanization, the demand for urban housing is increasing. With the rapid development of the housing construction market, due to the constraints of existing housing design and construction technology, it has been unable to meet the people's requirements for housing quantity and quality. . In addition, traditional housing has many problems such as slow construction speed, difficult quality control, high production cost, high energy consumption and pollution, which also seriously restricts the development process of housing industrialization.

[0002] Facing the rapid development of urbanization, the demand for urban housing is increasing. With the rapid development of the housing construction market, due to the constraints of existing housing design and construction technology, it has been unable to meet the people's requirements for housing quantity and quality.

In addition, traditional housing has many problems such as slow construction speed, difficult quality control, high production cost, high energy consumption and pollution, which also seriously restricts the development process of housing industrialization.

[0003] At present, the steel bar connection methods in prefabricated concrete structures at home and abroad mainly include sleeve grouting, restraint grout anchor, sleeve extrusion and other connection methods, but these connection methods have disadvantages in terms of cost, accuracy, construction efficiency, and construction quality. , which restricts the development of prefabricated shear wall structures, so developing a connection method with high construction efficiency, low cost and guaranteed quality is the key problem to be solved urgently
