Precast concrete wall panels are concrete wall components that are precast in a factory. They are characterized by standardized production and efficient construction, and have advantages such as high structural strength and good seismic performance. They are one of the core materials of modern building industrialization.

[0003] An existing patent (publication number: CN210976312U) discloses a precast concrete wall panel, including a wall panel body, the wall panel body including an end face and a side wall for connection, a connecting column protruding from the side wall of the wall panel, and a connecting groove recessed on the side of the wall away from the connecting column, the outer contour of the connecting column and the inner contour of the connecting groove are just matched and snapped together, and a plurality of first casting grooves are recessed circumferentially on the outer wall of the connecting column. In the process of realizing this utility model, the inventor found that the prior art has the following problems: the wall panel cannot quickly fix the upper and lower precast panels, and the wall panel is not further fixed after quick fixing, making the connection between the wall panels not stable enough.

[0004] Therefore, those skilled in the art provide a precast concrete component to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated concrete component. Compared to traditional prefabricated concrete components, this component achieves rapid installation of wall panels by setting a connecting seat. When installing floor slabs on the same floor, the first connecting groove on the connecting seat is aligned and assembled with the corresponding first connecting block on the wall panel. When installing upper and lower floor slabs, the floor slabs are aligned and assembled with the second connecting groove on the connecting seat, ensuring rapid and accurate alignment and installation between the wall and the connecting seat. Furthermore, by setting a steel reinforcement frame within the wall panel and the connecting seat, both the wall panel and the connecting seat are supported and stabilized. After alignment and assembly between the wall panel and the connecting seat, the steel reinforcement extending from the connecting seat is inserted into the grouting sleeve within the wall panel through the insertion hole, and grout is injected. Inserted steel reinforcement is installed in the guide hole of the sleeve body, and grout is injected into the guide hole through the grouting hole, thus ensuring the stability of the connection between the wall panel and the connecting seat.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A precast concrete component includes multiple wall panels and connecting seats. Multiple first connecting blocks are fixedly connected to the outer walls on both sides of the wall panels. Multiple first connecting grooves are formed on the outer walls of the connecting seats. The first connecting blocks and the first connecting grooves correspond one-to-one. Multiple first insertion holes are formed on the outer walls of the wall panels and the narrow outer wall of the connecting seats. Multiple second insertion holes are formed at both ends of the lower surfaces of the wall panels and the connecting seats.

[0008] The inner wall of the wall panel is provided with a first steel reinforcement frame, which includes multiple horizontal and vertical stirrups, multiple first vertical steel bars, and multiple first horizontal steel bars. The stirrups, first vertical steel bars, and first horizontal steel bars are all welded together. Grouting sleeves are fixedly connected to both ends of the first horizontal steel bars and the lower surface of the first vertical steel bars. Multiple guide holes are opened through both ends of the upper surface of the first connecting block and the first connecting groove. Inserted steel bars are provided on the inner wall of the guide holes. The inner wall of the connecting seat is provided with a second steel reinforcement frame, which includes multiple second vertical steel bars and multiple second horizontal steel bars. The second vertical steel bars and multiple second horizontal steel bars are all welded together. The second horizontal steel bars extend to the outside of the connecting seat.

[0009] Through the above technical solution, the precast concrete components can be quickly spliced ​​between wall panels through connecting seats. The cooperation of connecting grooves and connecting blocks can improve the convenience of assembly and the stability of the connection.

[0010] Furthermore, the upper ends of the second vertical reinforcing bars all extend to the outside of the connecting seat, and the lower surface of the second vertical reinforcing bars is also fixedly connected with a grouting sleeve.

[0011] Through the above technical solution, the second vertical steel bar is responsible for fixing the connecting seat between the upper and lower floors.

[0012] Furthermore, a second connecting block is fixedly connected to the middle of the upper surface of both the wall panel and the connecting seat, and a second connecting groove is opened in the middle of the lower surface of both the wall panel and the connecting seat;

[0013] The above technical solution enables rapid alignment and installation of upper and lower floors through the cooperation between the second connecting block and the second connecting groove, improving the speed and accuracy of assembly.

[0014] Furthermore, the upper ends of the first vertical reinforcing bars all extend beyond the upper surface of the wall panel, the first vertical reinforcing bars and the second insertion holes correspond one-to-one, the diameter of the second insertion hole is larger than that of the first vertical reinforcing bar, and the stirrups and the first horizontal reinforcing bars are all located inside the wall panel.

[0015] With the above technical solution, when the first vertical steel bar is spliced ​​between the upper and lower floor slabs, the first vertical steel bar of the lower layer enters the upper floor slab through the second insertion hole and is connected by the grouting sleeve, thereby connecting and fixing the upper and lower floor slabs.

[0016] Furthermore, the body of the grouting sleeve is fixedly connected with a grouting pipe and a grout outlet pipe, and the positions of the grouting pipe and the grout outlet pipe extend to the surface of the wall panel and the connecting seat.

[0017] The above technical solution involves grouting the inside of the grouting sleeve through a grouting pipe and discharging gas and excess grout through a grout outlet pipe, thereby completing the fixation between the reinforcing bars.

[0018] Furthermore, a grouting hole is provided through the middle of the upper surface of the first connecting block and the first connecting groove, and multiple grouting grooves are provided on the inner wall of the grouting hole, and the grouting grooves are connected to the guide hole;

[0019] The above technical solution involves injecting grout into the space between the wall panel and the connecting seat through the grouting hole, and into the guide hole through the grouting groove, to fill the gaps around the inserted reinforcing bars in the guide hole, thereby ensuring the stability between the wall panel and the connecting seat.

[0020] Furthermore, the second transverse reinforcing bar and the first insertion hole correspond one-to-one. The diameter of the first insertion hole is larger than that of the second transverse reinforcing bar. During the connection process, the second transverse reinforcing bar enters the first insertion hole and is connected to the first transverse reinforcing bar through a grouting sleeve.

[0021] Through the above technical solution, in the horizontal connection between wall panels, the horizontal steel bars in the connecting seat enter the wall panel through the first insertion hole and are connected by the grouting sleeve, thereby fixing the wall panel and the connecting seat.

[0022] This utility model has the following beneficial effects:
