[0004] A Chinese patent discloses a building concrete prefabricated panel (authorization announcement number CN219471340U), which is convenient for splicing multiple prefabricated panels by embedding the plug-in blocks in adjacent slots, and convenient for storing springs through the grooves. The elasticity of the springs facilitates the operation of the pressing plate to press downward, so that the limit blocks are clamped in the limit holes, thereby positioning the plug-in blocks, which is convenient for fixing the joints when the prefabricated panels are spliced;

[0005] However, it has certain disadvantages: when its spring is not under stress, the distance between the two pressure plates is the vertical length of the plug. Therefore, when the connection between the two prefabricated panels is under stress, one of the springs will be compressed, which will cause a limit block to move out of the limit hole, and thus the two prefabricated panels cannot remain in a neat and flat state. Therefore, its fixing method for the two prefabricated panels is not firm and reliable. Utility Model Content
