Description
Technical field
The present invention relates to assembled architecture technical field of construction, a kind of precast shear wall connection structure and its peace are particularly related to
Dress method.
Background technique
Assembly shear wall structure is a seed type of prefabricated concrete structure, and definition is main bearing member shearing
The prefabricated concrete structure that wall, beam, plate are partly or entirely made of precast concrete.Traditional fabricated construction carries out
When vertical connection, need to penetrate horizontal reinforcement after upper and lower wall is in place again, horizontal reinforcement often passes through a distance will be upper and lower
The end connection reinforcing bar of wall stops, need worker carry out it is time-consuming and laborious manually adjust, installation difficulty is very big, construction efficiency is low
Under；Moreover, this connection structure when carrying out installation, needs to lift the wall of top, avoid upper and lower wall
The connection reinforcing bar of end bends deformation；In addition, due to mutually being supported by the connection reinforcing bar of end between upper and lower wall, not
Plane docking just can guarantee that verticality, levelness etc. are assembled so fitness when upper and lower wall connecting needs cumbersome adjustment
Standard.
Summary of the invention
