[0002] Precast concrete panels refer to precast concrete parts that are produced and processed in a precast yard and transported directly to the construction site for installation. When making precast concrete panels, first a hollow model is made by nailing wooden boards. After steel bars are placed in the hollow part of the model, the hollow part is filled with cement. After it dries, the wooden boards are knocked off, and what remains is the precast concrete panel. The existing publication number CN220133257U discloses a precast concrete panel that is easy to assemble. Through the arrangement of the precast panel body, slots, fixing bolts, buckles, through holes, threaded steel bars, fixing slots and casting holes, when assembling the concrete panel in the long side direction, first remove the fixing bolts from the slots, and then insert the buckles into the slots. , install the fixing bolts on the slots through the through holes to ensure that the precast concrete panels will not slide against each other, extend the threaded steel bars into the fixing slots, pour concrete in the pouring holes, and wait for the concrete to solidify. The threaded steel bars are tightly combined with the precast panels, firmly and stably, thereby completing the function of splicing the concrete precast panels. However, the concrete precast panels need to be fixed and assembled on the long and short sides of the precast panels respectively, which reduces the efficiency of splicing the precast panels, increases the complexity of assembling the precast panels, and brings certain adverse effects on actual use, so improvements are needed.
