Embodiment Construction

[0021] Below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention will be further described:

[0022] figure 1 It is a schematic diagram of the vertical reinforcement connection between the upper wall body 1 and the lower wall body 2 of the prefabricated integral shear wall of the present invention, and figure 2 corresponding figure 1 A-A sectional view of the upper wall body 1 of the medium shear wall. Such as figure 1 , figure 2 As shown, a prefabricated integral shear wall, its main components include: the upper wall 1 of the shear wall structure, the lower wall 2, the reserved hole 3, the spiral stirrup 4, and the vertical reinforcement 6. The vertical stressed steel bars 6 protruding from the top of the lower wall 2 are clustered in groups, and then respectively extend into a reserved hole 3 preset at the bottom of the upper wall 1, wherein the inner wall of the reserved hole 3 is pre-buried vertically With the ...

Abstract

The invention discloses a prefabricated integral type shear wall. The prefabricated integral type shear wall comprises an upper wall body and a lower wall body; cylindrical reserved holes are vertically formed in two ends of the bottom of the upper wall body; vertical spiral stirrups with same heights are arranged in the reserved holes; exhaust vents which are communicated with the outside are formed in the top ends of the reserved holes; grouting holes which are communicated with the outside are formed in the lower parts of the reserved holes; vertical steel bars at the inner sides in edge constructional elements in the lower wall body extend out of the top of the lower wall body and then are bundled in groups, and the multiple grouped steel bar bunches are respectively inserted into the corresponding reserved holes till to be up to the tops of the reserved holes; and concrete mortar is filed between each steel bar bunch and each reserved hole. The prefabricated integral type shear wall has the advantages of being capable of reducing the construction difficulty of overlapping joint of the steel bar bunches, effectively restricting concrete in a compressive zone and being used for the overlapping joint among the vertical steel bars in a prefabricated integral type concrete shear wall system.

Description

technical field [0001] The invention relates to a vertical reinforcement connection technology for prefabricated concrete assembly integral shear walls, and belongs to the technical field of prefabricated concrete structures in construction engineering. Background technique [0002] The shear wall structure has high bearing capacity and anti-sway stiffness, can effectively resist horizontal shear force, and has good seismic performance. After the introduction of prefabricated assembly technology, the precast concrete assembly integral shear wall structure also has the advantages of facilitating factory standardized production, less wet work on site, convenient construction, less impact on the surrounding environment, and reduced transportation resources and labor resources. Therefore, with the actual needs of my country's construction industrialization and housing industrialization, the precast concrete assembly integral shear wall structure will have broad application prosp...
