Problems solved by technology

However, this type of member is greatly affected by the steel ratio of the section. When the steel ratio of the section is high, the lateral resistance of the CFST shear wall is greatly improved, but it also greatly increases the weight and steel consumption, and improves the construction efficiency. the cost of

Abstract

The invention discloses a concrete composite shear wall and a construction method thereof. The concrete composite shear wall comprises a concrete wall body and a plurality of PVC (Poly Vinyl Chloride) concrete pipes which are separately arranged along the length direction of the concrete wall body and are vertically embedded into the concrete wall body; two grid nets formed by steel bars are respectively arranged in the concrete wall body in each of two sides of a PVC concrete pipe array; the two grid nets are connected with each other through steel tie bars. The concrete composite shear wall is low in self weight, low in consumption of steel and low in cost, and is capable of ensuring that the structure has enough overall earthquake resistance.

Description

[technical field] [0001] The invention relates to a shear wall of civil engineering, in particular to a concrete composite shear wall and a construction method thereof. [Background technique] [0002] Modern buildings put forward higher requirements for the seismic capacity of high-rise and super high-rise buildings. Shear walls are still the main seismic components of today's high-rise and super high-rise structures. They are widely used in frame-shear wall structures and shear wall structures. Structure, frame—core tube structure, tube-in-tube structure. With the development of modern high-rise structures, in order to meet the needs of lateral seismic resistance of the overall structure, the traditional reinforced concrete shear wall tends to increase the section size, resulting in an increase in the structure's own weight, further increasing the earthquake response, and increasing the section will lead to The reduction of the actual use area; or the use of high-strength ...
