Design and construction method of multi-functional lifting ring connection node of longitudinal rib hollow wall panel

Abstract

The design and construction method of the multifunctional suspension ring connection node of the longitudinal rib hollow wall panel of the present invention belongs to the technical field of building structures. In the longitudinal rib of the slab, and the top of the steel hoisting ring protrudes out of the prefabricated wall panel, the steel hoisting ring is arranged along the vertical length. The constraining stirrups are spiral stirrups, and the constraining stirrups are arranged around the upper section of the reinforcement ring. The tie bars are tied between the junctions of the reinforcement rings and the reinforcement mesh of the wall panel along the thickness direction of the prefabricated wall panel. The invention can realize the setting of hanging points in the longitudinal rib hollow prefabricated wall panel with the through cavity, reduce the self-weight of the longitudinal rib hollow prefabricated wall panel, reduce the size of the wall panel and improve the installation efficiency. The invention can realize the multi-functional integration of the setting of the lifting point and the arrangement of the tie bars, optimize the process and improve the construction efficiency. The multi-functional hoisting ring connection node of the invention has reasonable force, and can facilitate the self-processing of the factory and reduce the production cost.

Description

technical field [0001] The invention belongs to the technical field of building structures, and particularly relates to a design and construction method for connecting nodes of multifunctional suspension rings of longitudinal rib hollow wall panels. Background technique [0002] Longitudinal rib hollow wall panels usually need to be provided with lifting points for connection with lifting tools such as shackles, lifting wires, and lifting beams. At present, the commonly used lifting points for prefabricated walls mainly include three categories: (1) pre-buried lifting points, such as tool lifting rings and steel lifting rings; (2) pre-embedded lifting nails; (3) reserved hole through-core lifting points. At present, the common hanging point connection node requires a large longitudinal rib area, which cannot be applied to the longitudinal rib hollow wall panel through the cavity. Moreover, when installing the tie bars at the longitudinal ribs of the wall panel, additional r...
