Scope

Main technical content: The prefabricated hollow wall panels are provided with vertical hollow holes, and the horizontal and vertical distribution reinforcement bars of the wall body, as well as the stirrup reinforcement bars of some edge components, are prefabricated therein. These prefabricated concrete shear wall components are referred to as prefabricated hollow wall panels. The prefabricated hollow wall panels of the core-filled precast concrete shear wall structure are installed on-site. The vertical reinforcement bars of some edge components of the prefabricated hollow wall panels are mechanically connected in the hollow holes, and the vertical distribution reinforcement bars of the wall body are non-contact lap-spliced in the hollow holes. The hollow holes of the prefabricated hollow wall panels are filled with cast-in-place concrete, and the prefabricated hollow wall panels are connected horizontally and vertically to form an assembled monolithic concrete shear wall structure, including some frame-supported core-filled precast concrete shear wall structures. The core-filled concrete is poured into the hollow holes of the prefabricated hollow wall panels. The core-filled concrete can be ordinary concrete or self-compacting concrete, and the construction process used should be consistent with the type of concrete adopted. The design of the core-filled precast concrete shear wall structure should carry out technical planning at the stage of building scheme design, and adopt a system integration method to coordinate the design, production, transportation, construction and installation, and operation and maintenance to achieve full-process collaboration. The technical selection, technical and economic feasibility, and constructability should be evaluated, and the construction targets and technical implementation plans should be determined scientifically and reasonably. The hanging rings of the prefabricated hollow wall panels should be made of un-cold-worked HPB
