Longitudinal rib hollow wallboard, multifunctional hanging ring connecting joint of longitudinal rib hollow wallboard and design construction method thereof

Abstract

The invention relates to a longitudinal rib hollow wallboard and a multifunctional hanging ring connecting joint and a design construction method thereof, and belongs to the technical field of building structures. The connecting joint comprises a steel bar hanging ring, a constraint stirrup and a tie bar, the steel bar hanging ring is arranged in a wallboard longitudinal rib in the thickness direction of a prefabricated wallboard, the top of the steel bar hanging ring extends out of the prefabricated wallboard, and the steel bar hanging rings are vertically arranged in a full-length mode; the constraint stirrups are spiral stirrups and are arranged around the upper section of the steel bar hanging ring; and the tie bars are tied at the joints of the reinforcing steel bar hanging rings and wallboard reinforcing steel bar meshes in the thickness direction of the prefabricated wallboard. The lifting points can be arranged in the longitudinal rib hollow prefabricated wallboard with a through cavity, the dead weight of the longitudinal rib hollow prefabricated wallboard is reduced, the size of the wallboard is reduced, and the installation efficiency is improved; multifunctional integration of lifting point arrangement and tie bar arrangement can be achieved, the working procedure is optimized, and the construction efficiency is improved; and the multifunctional hanging ring connecting joint is reasonable in stress, factory self-machining can be facilitated, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a longitudinal rib hollow wall panel and its multifunctional ring connection node and a design and construction method. Background technique [0002] Longitudinal rib hollow wall panels usually need to be provided with lifting points for connection with lifting tools such as shackles, hanging wires, and hanging beams. At present, the commonly used hanging points of prefabricated walls mainly include three types: (1) pre-embedded lifting rings, such as tool rings and steel bar rings; (2) pre-embedded hanging nails; The current common hanging point connection nodes require a large longitudinal rib area, which cannot be applied to longitudinal rib hollow wall panels with through cavities. Moreover, when the tie bars are installed at the longitudinal ribs of the wall panels, additional reinforcing bars need to be provided in the longitudinal ribs of the wall ...
