Prefabricated shear wall double-row steel bar connecting structure system

Abstract

A prefabricated shear wall double-row steel bar connecting structure system comprises an upper prefabricated shear wall, a lower prefabricated shear wall and a horizontal building member located between the upper prefabricated shear wall and the lower prefabricated shear wall and connected with the upper prefabricated shear wall and the lower prefabricated shear wall. The upper prefabricated shear wall and the lower prefabricated shear wall are the same in structure, and double-row steel bars and connecting boxes fixedly connected with the bottom ends of the double-row steel bars correspondingly are pre-embedded in both the upper prefabricated shear wall and the lower prefabricated shear wall. The upper portions of the double-row steel bars pre-embedded in the lower prefabricated shear wall stretch out from the top ends of the lower prefabricated shear wall and penetrate through the horizontal building member to be connected and fixed to the connecting boxes pre-embedded in the bottom of the upper prefabricated shear wall. Bending resistant capacity and shear resistant capacity are strengthened by multiple times, and the anti-seismic and anti-overturning performance of a building is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated shear wall double-row reinforcement connection structure system. Background technique [0002] In the existing building structure system, most of the connections between building components use sleeves as steel bar connectors, such as mechanical sleeves and grouting sleeves; this kind of sleeve connection structure makes it difficult for the steel bars protruding from the ends of building components to Aligned with the sleeve, the construction is difficult and the efficiency is low. For example, the grouting sleeve has high requirements for slurry preparation, and it is difficult to fill the grout. After a long time, the slurry is easy to age and shatter, resulting in loosening of the steel bar and low structural strength, which affects the quality of the building. Another example is the mechanical sleeve, where the end of the building...

Problems solved by technology

[0002] In the existing building structure system, most of the connections between building components use sleeves as steel bar connectors, such as mechanical sleeves and grouting sleeves; this kind of sleeve connection structure makes it difficult for the steel bars protruding from the ends of building components to Aligned with the sleeve, the construction is difficult and the efficiency is low

For example, the grouting sleeve has high requirements for slurry preparation, and it is difficult to fill the grout. After a long time, the slurry is easy to age and shatter, resulting in loosening of the steel bar and low structural strength, which affects the quality of the building. Another example is the mechanical sleeve, where the end of the building component protrudes slightly from the steel bar. Deviated from the center line of the mechanical sleeve, the screw thread at the end of the steel bar and the internal thread screw at the end of the mechanical sleeve cannot be inserted and installed. This is a technical problem that has not been solved for a long time in the field of construction engineering technology; in addition, building components The connecting steel bars are pre-embedded in the middle of the building components in a single row vertically, so that the bending and shearing resistance of the connecting nodes between the building components and the building components is poor, which affects the earthquake resistance, anti-overturning performance and building quality of high-rise buildings.
