Fabricated concrete shear wall structure vertical rigid connection joint and construction method thereof

Abstract

The invention relates to a fabricated concrete shear wall structure vertical rigid connection joint and a construction method thereof. The fabricated concrete shear wall structure vertical rigid connection joint comprises an upper limb concrete shear wall structure and a lower limb concrete shear wall structure which are vertically connected. An H-shaped steel structure or / and a connecting steel plate structure are fixedly connected between the upper limb concrete shear wall structure and the lower limb concrete shear wall structure. According to the technical scheme, construction is easy, theforce performance of the connection position is good, and the complexity of vertical connection of a fabricated concrete shear wall structure is greatly simplified.

Description

technical field [0001] The invention relates to the technical field of node connection of prefabricated building structures, in particular to a vertical rigid connection node of a prefabricated concrete shear wall structure and a construction method. Background technique [0002] The prefabricated shear wall structure is a structural form for high-rise and small high-rise residential buildings. Most of its components are prefabricated in factories and assembled at the construction site. Compared with the construction method of cast-in-place shear wall structure, it can save energy and materials, shorten the construction period, and has a wide development space. Therefore, in the development of prefabricated concrete structure system in my country, the prefabricated shear wall structure occupies an important proportion. [0003] One of the key problems of the prefabricated shear wall structure is the solid connection of the shear wall (that is, the horizontal joint connectio...

AI Technical Summary

Problems solved by technology

[0004] Wet connection includes cast-in-place belt connection, sleeve grouting connection, and reserved hole grout-anchor overlap. Wet connection has the advantages of good integrity, mature construction method, and low technical requirements, but this method has long construction period, low production efficiency, and Construction quality is difficult to guarantee;

[0005] Dry connection includes bolt connection, post-tensioned connection, keyway connection, and Wall Shoes connection. Dry connection has short construction period, high production efficiency, material saving, less wet work on site, and high construction quality, but it requires high construction accuracy.
