Connection nodes and connection methods of vertically distributed steel bars in prefabricated circular hole plate shear walls

Abstract

The invention discloses a connection node and a connection method for vertically distributed reinforcements on an assembly type round hole perforated plate shear wall, and belongs to the technical field of architectural engineering. The connection node comprises the vertically distributed reinforcements, an initial installation layer connection reinforcement, connection reinforcements, a long spacer bar, a short spacer bar, precast concrete and post-cast concrete. The connection between the vertically distributed reinforcements on the hollow assembly type round hole perforated plate shear wallis realized through the connection reinforcements; no external thrown reinforcements are arranged in the vertical direction of the precast wall panel of the round hole perforated plate shear wall, sothat convenience is provided for precast of the precast wall panel of the round hole perforated plate shear wall; requirements of production, processing and maintaining on the space can be reduced, the space of the transportation and storage can be reduced, and the storage and transportation of the precast wall panel of the round hole perforated plate shear wall is benefited; the connection between the vertically distributed reinforcements on the assembly type round hole perforated plate shear wall is realized through the connection reinforcements, the connection is simple, the operation is convenient, and the positioning of the connection reinforcements is easily adjusted; and the connection method for vertically distributed reinforcements on the assembly type round hole perforated plateshear wall is high in quality, high in efficiency and low in cost.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a connection node and a connection method of a vertically distributed steel bar of an assembled circular hole plate shear wall. Background technique [0002] There are currently many technical solutions for the connection nodes and connection methods of the vertically distributed steel bars in the prefabricated circular hole plate shear wall, but so far, no technical solution can determine the dominant position in the market, and there are always endless Desirable disadvantages, or there are hidden concerns about project quality. [0003] At present, my country's current engineering construction technical standards mainly include the following technical solutions for the connection of vertically distributed steel bars in prefabricated circular hole plate shear walls: The first one is "Technical Regulations for the Application of Steel Bar Sleeve Grout...

AI Technical Summary

Problems solved by technology

However, this technology has been questioned due to the difficulty of inspection and the large influence of human factors. There are many people who think that the quality is unstable and unreliable.

[0004] The second type is "Technical Regulations for Sleeve Extrusion Connection of Ribbed Steel Bars" JGJ108-96. This steel bar connection technology is only suitable for the steel bar connection of prefabricated concrete structures under the condition of operating space, and can be used for horizontal steel bar connections. Applicable, but not practical for vertical steel bar connection, and the difficulty of steel bar connection in prefabricated concrete structures lies in the connection of vertical steel bars

However, this technical solution has the disadvantages that the outer steel bars on the top of the precast concrete shear wall are longer, occupying a large space for production, the outer steel bars increase the difficulty of producing prefabricated wall panels, reduce production efficiency, and the outer contour of prefabricated wall panels Disadvantages such as large size and inconvenient transportation
