The invention discloses a self-thermal-insulation laminated slab type shear wall with built-in hidden supports. The shear wall comprises precast concrete layers, a thermal insulation plate, a cast-in-situ concrete layer, transverse steel bars, vertical steel bars, lattice steel bars, stirrups, U-shaped joint bars, a foundation beam and diagonal stiffeners (the hidden supports). The lattice steel bars are welded to the vertical steel bars located on one side, then are pressed into another precast concrete layer, and mainly play roles in enabling the precast concrete layers to be connected and enabling a laminated layer and the cast-in-situ concrete layer to operate collaboratively; the U-shaped joint bars are located at the bottom of the shear wall and enable the foundation beam and a wall body to be stressed collaboratively; the thermal insulation plate is arranged between the laminated layer and the cast-in-situ concrete layer and can improve the thermal insulation performance of the wall body. The diagonal stiffeners (the hidden supports) are welded to a steel bar framework formed by the transverse steel bars and the vertical steel bars to enhance the shearing resistance of the wall body under the earthquake action and meanwhile enable the foundation beam and the wall body to be stressed collaboratively.
