Two sides are connect with prefabricated post-wall built-in fitting respectively, I-shaped column-wall connecting key 4 by upper and lower two convex ribs respectively with prefabricated post-
Two groove inserting cooperations up and down of wall built-in fitting.In addition, the two sides upper and lower side of vertical plate 21 opens up reinforcing bar future insufficiency respectively
5, after I-shaped column-wall connecting key 4 assembles, reinforcing bar can be worn into reinforcing bar future insufficiency 5.
(2) number of circular hole 3 is 4 groups 8, parallel arrangement.The diameter of circular hole 3 be 20mm, with guarantee shear wall laterally by
Power muscle 9 can pass through circular hole 3.
(3) width of ribbed steel 2 needs the width than prefabricated post 18 (Fig. 6) and precast shear wall 19 (Fig. 9) 20mm small,
The requirement for preventing junction steel plate from corroding.
(4) shearing that the shear wall and intercolumniation that I-shaped column-wall connecting key 4 (Fig. 3) quantity is connected according to it transmit
Calculate determination.
(2) as shown in Fig. 1, fig. 4 to fig. 6, specific structure and the manufacturing process difference of prefabricated post are as follows:
(1) prefabricated post 18 is by longitudinal stress muscle 6, prefabricated column tie-bar 7, vertical reinforcement sleeve 1 and ribbed steel 2 in prefabricated post
Casting concrete forms, and longitudinal stress muscle 6 forms frame by the connection of prefabricated column tie-bar 7 in four prefabricated posts of the arrangement that is square
Structure, the bottom of longitudinal stress muscle 6 is set with vertical reinforcement sleeve 1 in each prefabricated post, and the one side of the frame structure is from upper
Prefabricated post-wall built-in fitting is uniformly arranged under and, concreting is in frame structure inner side and outer side.
(2) manufacturing process of prefabricated post 18 are as follows: firstly, vertical reinforcement is inserted into the lower end of longitudinal stress muscle 6 in prefabricated post
Then sleeve 1 binds prefabricated column tie-bar 7, complete the steel bar arrangement in prefabricated post.
The upper end of longitudinal stress muscle 6 should reserve a part in prefabricated post, and it is vertical that the length of reserved part should be prefabricated post
The half of 1 height of reinforced bar sleeve.
By prefabricated post-wall built-in fitting through hole fixation with steel wire on prefabricated column tie-bar 7, prefabricated post-wall built-in fitting
Number is determining according to the shear force calculation for needing to transmit between precast shear wall 19 and prefabricated post 18, and along 18 short transverse of prefabricated post
It is uniformly distributed.
Reinforcing bar outer support template in prefabricated post 18, casting concrete, concrete should pour in template to prefabricated post-
The outer surface of wall built-in fitting, form removal after concrete setting complete the production of prefabricated post.

Prefabricated post-wall built-in fitting is respectively set in side, and concreting is in framework of steel reinforcement inner side and outer side；Framework of steel reinforcement is that shear wall is longitudinal
The lateral stressed muscle 9 of principal rod 8, shear wall, shear wall confined boundary member stirrup 10 and shearing wall lacing wire 11 form, two rows shearing
Wall longitudinal stress muscle 8 is oppositely arranged in parallel, and is connected between every row's shear wall longitudinal stress muscle 8 by the lateral stressed muscle 9 of shear wall,
It is connected between the shear wall longitudinal stress muscle 8 being oppositely arranged by shearing wall lacing wire 11, the side of two rows of shear wall longitudinal stress muscle 8
Shear wall confined boundary member stirrup 10 is arranged in parallel in outside up and down between edge.
(2) manufacturing process of precast shear wall are as follows: binding shear wall longitudinal stress muscle 8 and shear wall constrained edge structure first
Part stirrup 10 forms confined boundary member reinforcing bar, then binds remaining shear wall longitudinal stress muscle and the lateral stressed muscle of shear wall
9, finally binding shearing wall lacing wire 11, forms the reinforcing bar in precast shear wall.
Prefabricated post-wall built-in fitting is that shear wall side is fixed on by metal binding wire, and metal binding wire passes through prefabricated post-wall
Reserved circular hole above built-in fitting is bound in precast shear wall on confined boundary member stirrup, wall it is laterally uniform
Two side areas.
The formwork supporting plate on the outside of framework of steel reinforcement, casting concrete, concrete should be poured in template to outside column wall built-in fitting
Side surface.Form removal after concrete setting completes the production of precast shear wall.
(4) as shown in Figure 18 to Figure 19, the specific structure of connecting portion balustrade deching and production between prefabricated post and shear wall
Process is as follows:
