Technical Field

[0001] The invention relates to the technical field of PC component splicing, and in particular to an assembled PC component splicing structure and method. Background Art

[0002] PC components refer to precast concrete components. Common PC components include floor slabs, balconies and walls. Existing PC component walls are generally fixedly connected with bolts and other connectors, and concrete is poured after the connection. However, the existing bolt connection operation is inconvenient, and multiple bolts need to be installed during the connection process, which affects the work efficiency.

[0003] According to the spliced ​​PC component building wall described in patent number CN213868427U, when it is used, it is connected through a connecting mechanism, and only a pulling force in the left and right directions can be applied. The connecting mechanism has no positioning in the front and back directions, and it is easy to fall off due to loose fixation during fixation. Summary of the invention

When in use, the user first aligns the slot on the wall with the reserved steel pipe on the ground and inserts it, so that the wall is fixed. Repeat the above steps to fix another wall, and then the user aligns the ends of multiple clips with the ends of the connecting grooves in turn and embeds them into the corresponding connecting grooves, and then pulls the anchor outward to drive the clips to move in the connecting grooves, and then moves to the bottom of the limit plate, and limits the clips up and down by the connecting grooves, and limits the clips front and back by the limit plates, which can effectively prevent them from falling off, and then inserts the two threaded rods into the through grooves and threadedly connected together, and then rotates until the clip plate abuts against the inner groove on the surface of the clip, clamps the two clips, and then inserts the four extension sections of the steel bar ring into the corresponding insertion grooves respectively, and bundles the steel bar rings on the bundling grooves, tightens the steel bar connection group, applies circumferential tension to the four connectors, and the connection of the two walls is completed.
