Embodiment 1

[0040] A prefabricated sandwich insulation laminated concrete shear wall, reference figure 1 , including: prefabricated concrete wall panel 1, vertical reinforcement in the wall 2, horizontal distribution reinforcement in the wall panel 3, steel plate 4, web reinforcement 5, lower chord reinforcement 6, support vertical reinforcement 7, support horizontal reinforcement 8, post-cast concrete 10 and insulation layer 11.

[0041] The precast concrete wall panel 1 is composed of an outer leaf precast concrete wall panel and an inner leaf precast concrete wall panel. The vertical steel bars 2 in the wall, the horizontally distributed steel bars 3 in the wall panels, the steel plates 4, the web steel bars 5, the lower chord bars 6, the vertical bars 7 of the support and the horizontal bars 8 of the support jointly form a reinforced triangular truss floor deck.

[0042] refer to figure 1 and 2 , the structure of the reinforced triangular truss floor deck is as follows: several hor...

Embodiment 2

[0044] A prefabricated sandwich thermal insulation laminated concrete shear wall, the same as in Example 1, the difference is that: the concrete shear wall also includes a thermal insulation panel connector 9, and the outer leaf prefabricated concrete wall panel and the thermal insulation layer 11 are separated by thermal insulation The board connector 9 is connected.

Embodiment 3

[0046] A prefabricated sandwich thermal insulation laminated concrete shear wall, the same as in Example 1, the difference is that the outer leaves of the prefabricated concrete wall panels are also provided with horizontally distributed steel bars 3 in the wall panels that are vertically connected to the vertical steel bars 2 in the wall to form Steel mesh (reference image 3 ), one end of the insulation board connector 9 passes through the steel plate 4 and the insulation layer 11 and is fixed on the vertical steel bar 2 in the wall, so that the outer leaf prefabricated concrete wall panel, the steel plate 4 and the insulation layer 11 are tightly fixed together.

Abstract

The invention belongs to the technical field of concrete shear walls, and particularly relates to a precast sandwich insulation laminated concrete shear wall and a preparation method and application thereof. The concrete shear wall includes a precast concrete wallboard, vertical rebars in a wall, transversely distributed rebars in the wallboard, steel plates, web member rebars, lower chord rebars,support vertical bars, support transverse bars, post-pouring concrete and an insulation layer, the precast concrete wallboard is composed of an outer leaf precast concrete wallboard and an inner leafprecast concrete wallboard, and the vertical rebars in the wall, the transversely distributed rebars in the wallboard, the steel plates, the web member rebars, the lower chord rebars, the support vertical bars and the support transverse bars together form steel triangular truss floor bearing plates; and the outer leaf precast concrete wallboard, the insulation layer, the steel triangular truss floor bearing plates and the inner leaf precast concrete wallboard are connected successively, and the space between the steel triangular truss floor bearing plates form the area for the post-pouring concrete. The shear wall can ensure that the phenomenon of mold swelling does not occur when pouring concrete in a middle cavity.

Description

technical field [0001] The invention belongs to the technical field of concrete shear walls, and in particular relates to a prefabricated sandwich thermal insulation laminated concrete shear wall and a preparation method and application thereof. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and it is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Existing concrete shear wall exterior walls mainly include cast-in-place concrete shear walls, prefabricated concrete shear walls, and prefabricated laminated shear walls. In order to meet building energy-saving requirements, insulation layers are required. Among them, cast-in-place concrete shear wall and insulation board without demolition formwork: this kind of sh...
