Lattice 2 and internal model plate body 3 are by being fixed as one toward cast-in-place concrete in steel grid in construction.
As shown in Figure 3 and Figure 4, insulation plate body 4 is fixed with the external mold plate body 1 of the present embodiment.Insulation plate body 4 is along wall thickness side
To horizontal through hole is provided with, the short tube 2-3 in external mold plate body stretches out and is fixed in the horizontal through hole, and connection reinforcing bar 2-4 stretches out simultaneously
It is welded in short tube 2-3, and is wrapped by cast-in-place concrete.
Multiple tracks is provided with for the air flue hole 4-1 of dehumidifier of radiating on the outside of the insulation plate body 4 of the present embodiment, air flue hole 4-1 closes on
Warming plate outside is arranged and longitudinally through insulation plate body.Air flue hole 4-1 includes longitudinal gas channel hole and transverse air channel hole.
Core pole hole 5 is additionally provided with insulation plate body 4, core pole hole 5 includes horizontal core pole hole and is provided with longitudinal core of stem stem reinforcing bar 6
Post holes.Connection reinforcing bar 2-4 can be lengthened makes to weld with stem stem reinforcing bar 6 outside the extended shear wall in one end and by horizontal core pole hole,
When concrete is injected in steel grid 2 and stem stem longitudinal hole, being partly squeezed into transverse holes parcel wherein connection reinforcing bar 2-4 becomes
Hang the little outrigger of reinforced concrete of heat-insulation layer.
Intermediate board body >=the 130mm of the present embodiment, interior reinforced mesh 2-2 and outer reinforced mesh 2-1 are by being welded to each other
Lengthways main steel bar and laterally pair muscle composition, are provided with reinforcement 2-5 in steel grid（As shown in Figure 5 and Figure 6）.Interior reinforced mesh 2-2
It is by the lengthways main steel bar and horizontal stroke of the muscle trade mark according to architectural design parameter determination, diameter and its centre-to-centre spacing with outer reinforced mesh 2-1
It is welded to the arrangement of secondary muscle.It is at least provided with more than 3 in per square of short tube 2-3 on internal model plate body 3 and external mold plate body 1, short
Pipe diameter >=φ 26mm, short tube wall thickness >=1.5mm, length equal or exceed template body thickness.
When internal model plate body 3 and less 1 overall dimensions of external mold plate body, the precast shear wall manufacture method of the present embodiment, system
Make above-mentioned precast shear wall, comprise the following steps：
1）Before construction of building a wall, horizontal secondary muscle is welded as into lattice piece with reinforcing bar 2-4 is connected first, then lattice piece and lengthways main steel bar are mutually welded
Connect to form the steel grid 2 containing interior reinforced mesh 2-2 and outer reinforced mesh 2-1；
2）The external mold plate body 1 for being fixed with insertion plate body short tube is affiliated on outer reinforced mesh 2-1, insertion plate body will be fixed with short

In short tube 2-3 on template body 1, so that internal model plate body, external mold plate body 1 are welded with outer reinforced mesh 2-1 and interior reinforced mesh 2-2
It is fixed as one；It is outer with cement based cementitious matter filleting plug-hole in each plate body（Short tube hole）And batch scrape smooth；
3）In construction, plate body is lifted it is in place, by toward cast-in-place concrete in steel grid 2 by external mold plate body 1, reinforcing bar
Grid 2 and internal model plate body 3 are fixed as one.
In order to form RC Continuous formula shear wall structure, after one piece of shear wall is installed, adjacent upper strata is lifted
Shear wall, will be the lengthways main steel bar in the shear wall of upper strata wrong with the lengthways main steel bar in lower floor's shear wall after shear wall lifting in upper strata is in place
Position docking makes the lengthways main steel bar that termination folding has hook stretch into through floor space in the steel grid 2 in lower floor's shear wall, and
Arrange in the steel grid 2 that negative and positive angle is horizontal and the longitudinally connected reinforcing member of levels, it is cast-in-place enter concrete after.
After lifting is in place, product during in order to prevent shear wall upper end by wind-force or pour concrete compacted by jolting in steel grid 2
Raw partial center phenomenon, can be fixedly installed the non-dismantling formwork or laminated floor slab of cast-in-place walls to replace in the para-position of shear wall upper end elder generation
It is conventional to position support bars by bodies of wall in a large number.
When large bay floor template is constructed, interim jacking beam in the middle part of floor template, must be set（Steel pipe）, because of lower floor's flooring now
Pouring concrete is not yet hardened, thus outside the part tension rib spreading during shear wall bottom or middle part steel pore can be arranged on a small quantity
Stretch, to arrange a small amount of support bar by standing on metope and the interim pipe back support floor template of splayed Jing.When hollow in shear wall
It is the interim joist of dismountable upper shifting and its support after the cast-in-place concrete of layer and reinforced concrete floor and the hardening of non-dismantling formwork layer
Bar, and overhanging section of tension rib is wiped out, so repeatedly until top layer.
Embodiment two
The precast shear wall of the present embodiment, is the improvement on the basis of embodiment one, as shown in fig. 7, different from embodiment one
It is：Due to internal model plate body 3 and 1 overall dimensions of external mold plate body it is larger and relatively thin, the internal model plate body 3 and external mold plate body 1 of the present embodiment
The thin formwork structure of steel wire concrete, intermediate board body >=130mm are adopted.Stretch out internal model plate body in short tube 2-3 one end in internal model plate body 3
3 and be welded and fixed with interior reinforced mesh 2-2, the short tube 2-3 one end in external mold plate body 1 stretch out external mold plate body and with outer reinforced mesh
2-1 is welded and fixed.
The precast shear wall manufacture method of the present embodiment, makes above-mentioned precast shear wall, comprises the following steps：
1）Before construction of building a wall, the external mold plate body 1 for being fixed with insertion plate body short tube is affiliated on outer reinforced mesh 2-1, will be outer
Short tube 2-3 on template body 1 is welded and fixed on outer reinforced mesh 2-1, and the internal model plate body 3 for being fixed with insertion plate body short tube is hung
Lean against on interior reinforced mesh 2-2, the short tube 2-3 on internal model plate body 3 is weldingly fixed on interior reinforced mesh 2-2；
