Prestressed Hoop Confined High Expansion Concrete Wall Panel, Shear Wall and Construction Method

Abstract

The invention provides a prestressed hoop constrained high-expansion concrete shear wall. The prestressed hoop constrained high-expansion concrete shear wall is composed of prestressed hoop constrained high-expansion concrete wall plates, hoop steel plates, prestressed tendons, reinforcing screw rods and box type steel connecting pieces, wherein the reinforcing screw rods on the adjacent prestressed hoop constrained high-expansion concrete wall plates penetrate through screw rod fixing holes in flanges on the two sides of the box type steel connecting pieces correspondingly and are fixed, so that the two adjacent prestressed hoop constrained high-expansion concrete wall plates are connected and fixed, and thus the prestressed hoop constrained high-expansion concrete shear wall for an assembled core cylinder structure is formed. The prestressed hoop constrained high-expansion concrete shear wall is high in shear bearing capacity and deformation resistance, applied to the assembled corecylinder structure, less in on-site wet operation, simple and rapid in construction and low in cost.

Description

technical field [0001] The invention generally relates to the field of building structure engineering, and mainly relates to a high-expansion concrete shear wall, in particular to a prestressed hoop-constrained high-expansion concrete wall plate, a shear wall and a construction method. Background technique [0002] Persisting in saving resources and protecting the environment is the basic national policy of our country, which is related to the vital interests of the people and the survival and development of the Chinese nation. The prefabricated core tube structure has the characteristics of high production efficiency and ecological environmental protection of prefabricated buildings. It is suitable for high-rise residential buildings and meets the development requirements of "residential industrialization". Vigorously developing the prestressed high-expansion concrete shear wall applied to the prefabricated core tube structure is a good opportunity for the development and g...

AI Technical Summary

Problems solved by technology

[0004] At present, the engineering application of the prefabricated core tube structure is still in its infancy. The reason is that the prefabricated core tube structure assembled on-site with traditional prefabricated shear walls under the action of a large earthquake will cause damage to the entire prefabricated core tube structure. Structural damage, so there is an urgent need for a prefabricated shear wall structure and manufacturing method that is low in cost, simple in construction, and can greatly improve the energy dissipation capacity, shear bearing capacity, and deformation resistance of the prefabricated core tube structure
