Fabricated composite shear wall based on self-resetting composite end column-grouting anchor shear wall

Abstract

The invention discloses a fabricated composite shear wall based on self-resetting composite end column-grouting anchor shear wall. The fabricated composite shear wall comprises self-resetting composite end columns, a grouting anchor shear wall, and energy dissipation connecting parts, wherein embedded double-layer concrete-filled steel pipe composite columns are connected in a pressed mode throughunbonded prestress, and inner steel pipes are taken as unbonded prestressed reinforced channels at the same time; the grouting anchor shear wall is connected by single row of reinforcing steel bars through grouting anchors, and shear wall reinforcing cages are made of factory-made steel meshes with stirrups; the energy dissipation connecting parts are made of high-strength steel plates with elliptical holes; the self-resetting composite end columns and the grouting anchor shear wall are connected through the energy dissipation connecting parts to form the integral fabricated composite shear wall. According to the fabricated composite shear wall based on the self-resetting composite end column-grouting anchor shear wall, the defects that existing 'equivalent cast-in-place' type fabricatedconcrete structure technologies have theoretical, technical and economic problems are overcome, and the prefabricated composite shear wall with efficient prefabricating, simplified construction and definite stress is realized.

Description

technical field [0001] The invention relates to an assembled composite shear wall based on a self-resetting combined end column-grout anchor shear wall, which belongs to the technical field of assembled concrete structures in construction engineering. Background technique [0002] "Equivalent to cast-in-place" prefabricated concrete structure technology, due to its conceptual advantages of being closely connected with cast-in-place concrete structures and relatively mature technology, matches my country's short-term goal of realizing the leapfrog development of prefabricated concrete structures, and also brings In recent years, the remarkable development of prefabricated concrete buildings in China. However, in the process of summarizing and analyzing a large number of research results and practical experience in recent years, it was found that the concept of "equivalent to cast-in-place" still lacks theoretical models and analysis methods to reflect its own stress mechanism,...

Problems solved by technology

However, in the process of summarizing and analyzing a large number of research results and practical experience in recent years, it is found that the concept of "equivalent to cast-in-place" still lacks theoretical models and analysis methods that reflect its own stress mechanism, and the heavy workload of on-site wet work and steel bar binding leads to Low construction efficiency and poor construction quality, lack of market competitiveness with cast-in-place concrete structures, problems such as theory, technology and economy
