Embodiment two
As illustrated in figs. 13-15, the present embodiment provides the connection method of a kind of prefabricated component and concrete cast-in-situ layer, can be used for implementing
The first side wall in example one using iterative structure, the first laminate using the first side wall prefabricated component when complete cast-in-place or iterative structure with
The connection of first laminate in-situ layer or the first cast-in-place laminate can be used for the second side wall and be adopted using iterative structure, the second laminate
With the second side wall prefabricated component 16 when complete cast-in-place or iterative structure and the second laminate in-situ layer or reinforced concrete cast-in-situ layer 38
Connection；It is now illustrated by taking the connection method to the second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38 as an example, second side
The connection method of wall prefabricated component and the second laminate in-situ layer, the first side wall prefabricated component and the first laminate in-situ layer 37 or the first are cast-in-place
The connection method of laminate even is as it, and this will not be detailed here.
As shown in figure 12, the connection method of the second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38 is as follows:
Firstly, reserving the first U-shaped muscle in the top of reinforced concrete cast-in-situ layer 38 when reinforced concrete cast-in-situ layer 38 is constructed
20, the first U-shaped 20 both ends of muscle are inserted into reinforced concrete cast-in-situ layer 38 in a manner of U by falling, and the first U-shaped muscle 20 is reserved, and to stretch out reinforcing bar mixed
The length of solidifying soil in-situ layer 38 pours distance and rule according to the second side wall prefabricated component 16 and the interval of reinforced concrete cast-in-situ layer 38
The lap of splice as defined in model, which calculates, to be determined；
Secondly, the pre-buried second U-shaped muscle 22 in the second side wall prefabricated component 16, second is U-shaped when the second side wall prefabricated component 16 is prefabricated
The side of muscle 22 is protruded into the second side wall prefabricated component 16 from 16 bottom of the second side wall prefabricated component, and it is prefabricated that the other side is located at the second side wall
It is fixed for the second side wall in-situ layer 36 with later period cast in situs outside part 16；
Then, above-mentioned second side wall prefabricated component 16 is lifted to 38 top of reinforced concrete cast-in-situ layer, drawing close keeps the second side wall pre-
First U-shaped muscle 20 of U-shaped 22 bottom of muscle of the second of product 16 and reinforced concrete cast-in-situ layer 38 stretches out reinforced concrete cast-in-situ layer
38 partial transpositions are engaged overlap joint, and position, fix it is opposite between the second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38
Position；The position of first positioning member 21 and the first U-shaped muscle 20, the second U-shaped muscle 22 is independent of each other, and both ensure that the first positioning structure

A small amount of template need to only be set up by connecing areas outside, by cast-in-place mode by the second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38
The problem of connection forms overall structure, avoids structural member seam crossing leak, and guarantee connecting joint structure intensity.
The connection method of prefabricated component provided in this embodiment and concrete cast-in-situ layer is U-shaped by the first U-shaped muscle 20 and second
It is engaged connection between muscle 22, prefabricated component and concrete cast-in-situ layer are poured into integral structure by cast-in-place mode, not only solved
Prefabricated component connect difficult problem with concrete cast-in-situ layer scene reinforcing bar, and the first U-shaped muscle 20 and the second U-shaped muscle 22 are connected to
Reinforced concrete cast-in-situ layer 38, the second side wall prefabricated component 16, the second side wall in-situ layer 36, strengthen prefabricated component and concrete cast-in-situ
The stress intensity of the connecting node of layer, solves the problems, such as the existing easy leak of fabricated construction part seam crossing.
It further, can be in steel in order to which the second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38 is accurately positioned
Pre-buried second positioning member 23 in 38 upper surface of reinforced concrete in-situ layer, the corresponding position in the bottom of the second side wall prefabricated component 16 increase
It is fixed by first when lifting above the second side wall prefabricated component 16 to reinforced concrete cast-in-situ layer 38 if the first positioning member 21
Position component 21 and the second positioning member 23 are attached and position second side wall prefabricated component 16 and reinforced concrete cast-in-situ layer 38
Location efficiency and precision are improved in relative position, solve prefabricated component in existing fabricated construction part and position asking for performance difficulty
Topic.As a kind of implementation, the tune matched with the bottom of the first positioning member 21 can be increased on the second positioning member 23
Leveling device improves positioning accuracy.
Further, the equal arranged for interval in side more first lateral steel of the first U-shaped muscle 20 and 22 lap-joint of the second UXing Jin
Muscle 24, the first transverse steel 24 arrange perpendicular to the first U-shaped muscle 20 and the second U-shaped muscle 22, more first on the first U-shaped muscle 20
Transverse steel 24 and more first transverse steels 24 on the second U-shaped muscle 22 are positioned opposite, pass through setting for the first transverse steel 24
Set, cannot be only used for fixing the first U-shaped muscle 20 and the second U-shaped muscle 22, and can further strengthen the second side wall prefabricated component 16 with
Stress intensity at the connecting node of reinforced concrete cast-in-situ layer 38.In addition, it is prefabricated to be located at the second side wall on the second U-shaped muscle 22
