Sleeve-free grouting sandwich thermal insulation shear wall system

Abstract

The invention discloses a sleeve-free grouting sandwich thermal insulation shear wall system, and relates to the technical field of prefabricated shear wall systems. A prefabricated shear wall component is composed of an outer wall plate, a concrete rib plate, an inner wall plate, heat preservation plates, a weight reduction heat preservation plate, FRP connecting pieces, truss steel bars, wall body horizontal bars and coupling beam stirrups. The concrete rib plate is connected with the inner wall plate through two groups of upper and lower truss steel bars, chord bars of the truss steel barsare through and penetrate through the inner wall plate, and chord ribs of the upper truss steel ribs replace coupling beam stress ribs. The outer wall plate is connected with the concrete rib plate and the inner wall plate through the FRP connecting pieces, and the heat preservation plates are clamped between the outer wall plate and the concrete rib plate and between the outer wall plate and theinner wall plate. The advantages of cast-in-place and factory prefabrication can be brought into full play, on-site wet operation is reduced, sleeve-free connection is achieved, the cost is reduced, the construction quality is guaranteed, the structural integrity is equivalent to cast-in-place, and reliable technical support is provided for domestic assembled integral shear wall structure construction.

Description

technical field [0001] The invention relates to the technical field of prefabricated shear wall systems, in particular to a sleeve-free grouting sandwich thermal insulation shear wall system. Background technique [0002] At present, the domestic prefabricated shear wall system wall members longitudinal reinforcement connection mainly has the following types: mechanical connection, sleeve grouting connection, grout anchor lap connection, welding connection, binding lap connection, among which the sleeve grouting connection is the most popular in the market. Mainstream connection method. The sleeve not only has a high cost and increases the burden on the developer, but also has high rigidity and poor ductility, which causes the plastic hinge area of ​​the shear wall to move upward, which does not meet the assumptions of the original structural calculation model. The construction is difficult, the installation speed is slow, the fullness of grouting cannot be detected, the re...

The sleeve not only has a high cost and increases the burden on the developer, but also has high rigidity and poor ductility, which causes the plastic hinge area of ​​the shear wall to move upward, which does not meet the assumptions of the original structural calculation model. The construction is difficult, the installation speed is slow, the fullness of grouting cannot be detected, the requirements for construction personnel are high, the construction quality is difficult to guarantee, and there are certain safety hazards
