Member includes steel wire net rack 4 and the insulating layer 2 and pouring layer that are filled on steel wire net rack 4, and the insulating layer 2 is embedded in steel wire net rack 4
In, pouring layer is to be set to the precast concrete protective layer 1 of 2 side of insulating layer, and 1 outer end face of precast concrete protective layer is provided with
Mounting hole 5 is installed, auxiliary tension member 6 is embedded with inside precast concrete protective layer 1；The wall element of above structure composition is in work
Factory is prefabricated, is fixed after transport to scene and 2 inboard portion of cast-in-place thermal-insulating layer, formation cast-in-place concrete layer 3 are then successively solid
Determine and pour, form overlapped shear wall structure, the detailed process of construction is unfolded to illustrate by specific embodiment.
Specific embodiment, as shown in Figure 1, steel wire net rack 4 is truss structure form, steel wire net rack 4 is located at precast concrete
One end in protective layer 1 is vertically and transversely cross-linking bar-mat reinforcement, and it is in length and breadth that steel wire net rack 4, which is located at insulating layer 2 not pouring one end of side,
To cross wise reinforcement net or one-way reinforcement；The installation mounting hole 5 of 1 outer end face of precast concrete protective layer be unthreaded hole or bolt hole,
In specific prefabrication process, the barrel 12 that steel wire net rack 4 is provided through in mounting hole 5 is installed, blocking up when to avoid prefabricated pour
Plug, 12 port of barrel is provided with plug 13；Auxiliary tension member 6 is nut casing, U-shaped or Ω steel bars, the opening of nut casing
End, U-shaped or Ω steel bars elbow end are run through and are overhung at outside insulating layer 2, and the form that U-shaped steel muscle is chosen in the present embodiment is made
For auxiliary tension member, the construction of overlapped shear wall is carried out based on the wall element of above structure, it is as shown in Figures 2 and 3, described
Construction method includes the following steps：
A, prefabricated wall element is transported on working face and is fixed, side is not poured in the steel wire net rack 4 of wall element
Vertical applied force reinforcing bar 7 is set, is overhung on the elbow end outside insulating layer 2 in U-shaped steel muscle and connects anchoring tension member 8, anchoring
It is the reinforcing bar of drag hook to select both ends with tension member 8, is poured with template in the setting of the outside of vertical applied force reinforcing bar 7, then to insulating layer 2
Cavity between template carries out pouring to form cast-in-place concrete layer 3；
B, wall element upper surface installs upper layer wall element and vertical applied force reinforcing bar 7 is arranged in step, and the layer is vertical
7 lower end of steel bar stress is fixedly connected with 7 upper end of first layer vertical applied force reinforcing bar, and anchor is connected at this layer of U-shaped steel muscle elbow end
Admittedly using tension member 8, poured with template, upper wall unit outside and wall list below in the 7 outside setting of vertical applied force reinforcing bar
Vertical fixing piece 10 is set between first outside, and fixing piece 10 selects steel fixed plate, and flatness is good, is unlikely to deform, fixing piece
It is fixedly connected by bolt 11 between 10 and two wall elements, wall element is provided through in 5 position of installation mounting hole
The barrel 12 of steel wire net rack 4,12 port of barrel are provided with plug 13, and when fixed installation dismantles plug 13, fixing piece 10 by
Bolt 11 and the locking of barrel 12 coordinate wall element by upper wall unit and to be below fixedly connected.
C, the cavity between upper wall unit insulating layer 2 and template is poured, and forms cast-in-place concrete layer 3；
D, overlapped shear wall is formed after form removal, bolt 11, fixing piece 10, construction finishes；
E, step B, C, D is repeated until desired height.
The prefabrication process of wall element intersects at the prior art there is also difference in the present invention, as shown in figure 4, prefabrication process
Include the following steps：
A, prefabricated middle part carries the steel wire net rack 4 of insulating layer 2；
B, the rectangle that setting upper end opens pours framework 14, and steel wire net rack 4 is positioned over rectangle along upper end opening to be poured
In framework 14, insulating layer 2 is horizontal direction and its side pours 14 4 sides of framework with rectangle and is in contact respectively；In order to carry
The support strength of high steel wire net rack 4 is put into before rectangle pours framework 14 in steel wire net rack 4, in 4 bottom of steel wire net rack and its
One group of supporting block 9 is evenly arranged between middle part insulating layer 2；
C, the steel wire net rack 4 positioned at 2 top of insulating layer is poured, rectangle is removed after molding and pours framework 14, is formed
Wall element.
The prefabrication process of wall element takes full advantage of the supporting role of insulating layer, steel wire net rack, and insulating layer level is put
The steel wire net rack for pouring its upper layer is postponed, concrete layer is gradually adhesively fixed with insulating layer upper surface in maintenance processes, steel wire
Rack also acts as the position-limiting action of supporting role and heat-insulation unit, meanwhile, compared to after first pouring heat-insulation unit is bonded on upper layer
Mode, the application prefabrication process avoid insulating layer caused by bleed layering during concrete curing bond it is insecure even
The phenomenon that failure, the connection effect between entire insulating layer and precast concrete protective layer greatly promote, and it is more firm to form integraty
The precast wall body unit module leaned on.
The present invention carries out site operation by prefabricated wall element, is not poured using in wall element in work progress
Side carries out cast in situs, and the bonding strength between wall element is significantly improved, which both has modularization
The convenient advantage of constructing of assembled wall body, but also with the intensity of formed by integrally casting formula wall, high fit shear wall intensity requirement；
It is realized by the locking of precast concrete protective layer, fixing piece and bolt and barrel between upper and lower wall unit reliable
Be fixedly connected, and be not necessarily between the two it is additional to just, the operation of alignment and angular adjustment, cumbersome degree drops significantly
It is low；In addition, the connection that the prefabrication system of wall element greatly improves between heat-insulation unit and precast concrete protective layer is strong
Degree, the integrated degree higher of wall element.
