Prefabricated concrete element and shear wall module with same and manufacturing method thereof

Abstract

The invention relates to a prefabricated concrete component, a shear wall module with the component and a manufacturing method thereof. The prefabricated concrete components include: the first shear wall panel, and steel bars are arranged inside the first shear wall panel; The concealed frame columns on the right edge are integrally formed; the concealed frame beams on the upper edge, the concealed frame beams on the lower edge, the concealed frame columns on the left edge and the concealed frame columns on the right edge all have reinforced concrete slabs protruding from the first shear wall panel A grouting sleeve is pre-embedded in the hidden frame beam at the lower edge, a vertical steel bar protruding out of the hidden frame beam at the upper edge is pre-embedded, and a U-shaped closure protruding out of the hidden frame column at the left and right edges is provided. rebar. Prefabricated concrete components are used as a part of the shear wall module, and the manufacture of the shear wall module only needs to install hidden supports and connect firmly with another shear wall panel. There is a hidden support truss between the two shear wall panels, which has good seismic performance.

Description

technical field [0001] The invention relates to the technical field related to construction engineering, in particular to a prefabricated concrete component, a shear wall module with the component and a manufacturing method thereof. Background technique [0002] The shear wall structure has good anti-seismic performance, and has gradually become the structural form commonly used in residential construction in my country. [0003] Ordinary cast-in-place reinforced concrete shear walls mainly resist horizontal earthquake force through horizontal steel bars, but under earthquakes, ordinary cast-in-place shear walls are prone to brittle shear failure, and their ductility and energy dissipation capacity are insufficient. The existing prefabricated integral shear wall is just a simple split of the cast-in-place shear wall, which is difficult to meet the ductility and energy dissipation and anti-seismic requirements. [0004] The prefabricated concealed support energy-dissipating ...

Problems solved by technology

[0005] However, the single prefabricated concrete components of the existing prefabricated concealed support energy-consuming shear walls have many defects, specifically: on the one hand, during factory production, each single precast concrete component cannot be poured at the same time. For the force wall, only the bottom concrete slab steel bars and hidden frame steel bars can be bound first, the bottom concrete slab is poured, and after it reaches a certain strength, the shear wall steel bars are bound, and the hidden frame and shear wall panels are poured. It will increase the workload and production time; on the other hand, because it cannot be poured at the same time, the bonding integrity of the contact surface between the individual precast concrete components is not good
