In the above scheme, the base grout layer is utilized to realize the fixation of the prefabricated wall and the top plate, formwork erection and sleeve grouting are not needed, a large amount of construction time can be saved, and the labor intensity of workers is reduced.
In addition, through the lock structure of lug and notch, can realize rapid Assembly, need not additionally to increase stop device, also need not artifical the regulation repeatedly, the installation accuracy is high, and efficient.
Preferably, the projection and the recess are both arranged on the outer side of the top plate and the prefabricated wall.
Preferably, a vertically through restraining hole is formed in the top plate, the restraining hole is located at the joint of the top plate and the prefabricated wall, and a restraining reinforcing steel bar fixed with the prefabricated wall is arranged in the restraining hole.
Preferably, the constraint reinforcing steel bars are in clearance fit with the constraint holes.
Preferably, the length of the constraining reinforcing bar is shorter than the thickness of the top plate.
Preferably, the restraint reinforcing steel bars are integrally cast with the prefabricated wall.
Preferably, the restraint reinforcing steel bar penetrates through the base grout layer and is fixedly attached to the base grout layer.
Compared with the prior art, the beneficial effects of the utility model are that: greatly shorten the construction progress, cancel formwork work basically, also reduce a large amount of labours simultaneously, of high quality, better control, green construction, reduction building rubbish, maintain simply.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
Example one
As shown in fig. 1, the prefabricated wall 1 is a fully prefabricated wall, and the roof 2 is a fully prefabricated roof, which are overlapped.
The connected node of prefabricated wall and roof that this embodiment provided includes the seat thick liquid layer 3 that sets up between 2 lower terminal surfaces of roof and the prefabricated wall 1 up end, the one end on seat thick liquid layer 3 is the stair structure, and this step is through bending horizontally again downwards in proper order and forming.
The lower end face of the top plate 2 is provided with a convex block 21 which is attached to the upper surface of the step of the seat slurry layer 3, the upper end face of the prefabricated wall 1 is provided with a notch 11 which is attached to the lower surface of the step of the seat slurry layer 3, and the convex block 21 and the notch 11 are buckled to fix the seat slurry layer 3 between the convex block and the notch (as shown in fig. 2).
