Repairable multistage energy dissipation dry-type mixed fabricated type concrete shear wall

Abstract

The invention discloses a repairable multistage energy dissipation dry-type mixed fabricated type concrete shear wall. High-strength steel pipes are embedded in prefabricated concrete shear wall edgecomponents and are filled with high-strength concrete; the concrete shear wall edge components are connected through multistage energy dissipation pieces, the multistage energy dissipation pieces areconnected with the pre-buried high-strength steel pipes through end plate bolts, and middles of concrete shear wall bodies are connected through post-tensioning no-bonding prestress thread rebars; andthe multistage energy dissipation pieces are composed of top plates, bottom plates, steel pipe concrete bar bodies provided with constraint steel pipes, connecting plates and energy dissipation steelplates provided with diagonal stiffening ribs, only the energy dissipation steel plates and the connecting plates are connected through high-strength bolts, and other rod pieces are connected throughwelding. According to the repairable multistage energy dissipation dry-type mixed fabricated type concrete shear wall, dry-type connecting without cast-in-place concrete or grouting construction is achieved, meanwhile, the repairable multistage energy dissipation mixed fabricated type concrete shear wall is built, the working mechanism is clear, anti-seismic performance is good, the technical economic benefits are remarkable, and the repairable multistage energy dissipation dry-type mixed fabricated type concrete shear wall is especially suitable for being applied and promoted in an earthquake fortification area.

Description

technical field [0001] The invention relates to a repairable multi-stage energy-consuming dry mixed prefabricated concrete shear wall, which belongs to the technical field of prefabricated concrete shear wall structures in construction engineering. Background technique [0002] my country's construction industry urgently needs to be industrialized and upgraded. As one of the important ways to achieve construction industrialization, the prefabricated concrete structure has become a research and development hotspot, and the prefabricated concrete shear wall structure suitable for residential buildings with a broad application market has become a key research object. Due to the strict requirements for seismic fortification in my country, and the height of the shear wall structure is generally high, the current "equivalent to cast-in-place" prefabricated concrete shear walls often require the edge components to be cast in-situ. At the same time, the vertical reinforcement of the ...

Problems solved by technology

Due to the strict requirements for seismic fortification in our country, and the height of the shear wall structure is generally high, the current "equivalent to cast-in-place" prefabricated concrete shear walls often require the edge components to be cast in-situ. At the same time, the vertical reinforcement of the shear wall is generally connected by sleeves Grouting connection or grouting anchor connection, resulting in a large number of wet operations such as concrete pouring and grouting on site, can not give full play to the advantages of precast concrete technology, seriously restricting the real development of prefabricated concrete shear wall structure
