Full-prefabricated concrete shear wall and construction method thereof

Abstract

The invention discloses a full-prefabricated concrete shear wall and a construction method thereof. The full-prefabricated concrete shear wall comprises a plurality of layers of full-prefabricated shear wall plates which are fixed in a butt joint mode; each full-prefabricated shear wall plate comprises a prefabricated concrete body and a plurality of vertical butt joint steel bars which are distributed in a mode of penetrating through the prefabricated concrete body, a steel bar butt joint assembly is arranged on the lower portion of the interior of the prefabricated concrete body, the top ends of the vertical butt joint steel bars extend out of the upper surface of the prefabricated concrete body, and the bottom ends of the vertical butt joint steel bars are inserted into the steel bar butt joint assembly; and when the upper layer of full-prefabricated shear wall plate and the lower layer of full-prefabricated shear wall plate are fixed in a butt joint mode, the top ends of the vertical butt joint steel bars on the lower layer are inserted into the steel bar butt joint assembly on the upper layer and are fixed to the bottom ends of the vertical butt joint steel bars on the upper layer in a butt joint mode. According to the full-prefabricated concrete shear wall and the construction method thereof, full prefabrication of shear wall components can be realized, the on-site post-pouring concrete operation is greatly reduced, and the installation quality and efficiency of steel bar butt joint connectors are improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete structures, and in particular relates to a fully prefabricated concrete shear wall and a construction method thereof. Background technique [0002] At present, the prefabricated concrete shear wall structure mainly follows the concept of "equivalent to cast-in-place". In order to achieve "equivalent" to the traditional cast-in-place structure, it is often required that the edge members as important stress-bearing parts of the shear wall adopt post-cast concrete at the construction site. Form, the shear wall only prefabricates the wall part of the vertically distributed reinforcement area, which greatly reduces the prefabrication efficiency, and at the same time brings a lot of wet work of cast-in-place concrete, which is not conducive to ensuring the construction quality and further affects the structural performance. [0003] In addition, the steel sleeve grouting connection method...

[0002] At present, the prefabricated concrete shear wall structure mainly follows the concept of "equivalent to cast-in-place". In order to achieve "equivalent" to the traditional cast-in-place structure, it is often required that the edge members as important stress-bearing parts of the shear wall adopt post-cast concrete at the construction site. The shear wall only prefabricates the wall body in the vertically distributed reinforcement area, which greatly reduces the prefabrication efficiency, and at the same time brings a lot of wet work of cast-in-place concrete, which is not conducive to ensuring the construction quality and further affects the structural performance

[0003] In addition, the steel sleeve grouting connection method that can realize the butt joint connection of steel bars is generally used for the vertically distributed reinforcement connection of the prefabricated part of the shear wall. Frequent grouting quality problems
