Embodiment Construction

[0028] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0029] like figure 1 As shown, the present invention firstly provides a kind of prefabricated reinforced concrete shear wall, comprises upper section shear wall 2 and lower section shear wall 1, realizes the reliability continuity of the vertical reinforcing bar of wall body through three section connection, namely lower section shear wall The vertical reinforcement in the force wall is lapped with the section steel, the section steel sleeve is grouted, and the sleeve is lapped with the vertical reinforcement in the upper shear wall. Wherein, the section steel 4 is pre-embedded in the lower shear wall and located at both ends, and the sleeve 5 is pre-embedded in the upper shear wall and located at both ends. The section steel 4 corresponds to the position of the sleeve 5 .

[0030] Specifically, a section steel 4 is pre-embedded at both ends ...

Abstract

The invention provides a prefabricated reinforcing steel bar concrete shear wall. The prefabricated reinforcing steel bar concrete shear wall includes an upper-section shear wall body and a lower-section shear wall body, muff coupling pieces are embedded in the upper-section shear wall body, section bars are embedded in the lower-section shear wall body and exposed, the section bars penetrate into the muff coupling pieces in a matched mode, and mortar grouting is conducted in the section bars so as to make the upper-section shear wall body and the lower-section shear wall body connected with each other. According to the prefabricated reinforcing steel bar concrete shear wall, 'scattered connection mode' of reinforcing steel bars is improved into 'centralized connection mode' of the section bars, the problem that the reinforcing steel bars are difficult to insert and align is solved, and the connection efficiency of the construction is further improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated reinforced concrete shear wall. Background technique [0002] Compared with cast-in-place concrete structures, prefabricated prefabricated concrete structures have the characteristics of low resource consumption, low environmental impact, high labor productivity, and significant economic and social benefits. It is the development direction of my country's current construction industrialization. Like cast-in-place shear wall structure and frame-shear wall, prefabricated shear wall structure is suitable for high-rise residential buildings, while prefabricated frame-shear wall is suitable for office and shopping malls. For the horizontal joints of prefabricated shear walls, two key technical issues need to be solved: vertical reinforcement connection and horizontal joint connection. [0003] At present, the mainstream horizontal joint co...
