[0016] The utility model will be further explained in detail in combination with the drawings and specific embodiments.
[0017] EMBODIMENT
[0018] As shown in Figure 1 , Figure 2 and Figure 3 , the prefabricated building wallboard connecting structure provided by the embodiment comprises a wallboard body 1, the side edge of the wallboard body 1 is in the shape of a semicircular arc surface, a plurality of three-way connection boxes 2 matched with the thickness of the wallboard body 1 are uniformly embedded and mounted along the edge of the wallboard body 1 on the two adjacent sides of the wallboard body 1, one side of the three-way connection box 2 close to the surface of the wallboard body 1 is open, and a corresponding matching installation window is opened on the surface of the wallboard body 1, an installation hole 3 is opened in the center of the side of the three-way connection box 2 opposite to the installation window and close to the side wall of the wallboard body 1, and a connecting sleeve 4 corresponding to the three-way connection box 2 is embedded and mounted on the two sides of the wallboard body 1 without the three-way connection box 2.
[0019] When assembled, one side of one wallboard body 1 provided with the three-way connection box 2 is aligned and spliced with one side of another wallboard body 1 provided with the connecting sleeve 4, after the side edges of the two wallboard bodies 1 are aligned, the two semicircular side edge arc surfaces form a cylindrical channel, that is, a grouting hole 7; after subsequent assembly is completed, grouting treatment is carried out;
[0020] After the alignment of the wallboard plate body 1, the three-way connecting box 2 is aligned with the connecting sleeve 4, so that the high-strength bolt 6 and the gasket 5 are inserted through the mounting hole 3 of the three-way connecting box 2 to connect and fix the three-way connecting box 2 and the connecting sleeve 4, thereby realizing the assembly of two wallboard plate bodies 1, which is the assembly and connection mode of two wallboard plate bodies 1 in the same plane; when two wallboard plate bodies 1 are assembled, the wallboard plate body 1 needs to be assembled perpendicularly to the wallboard plate body 1, and only needs to align the side of the wallboard plate body 1 with the mounting connecting sleeve 4 with the position of the three-way connecting box 2 of the wallboard plate body 1 perpendicular thereto, and then connect and fix the three-way connecting box 2 and the connecting sleeve 4 through the gasket 5 and the high-strength bolt 6 after the alignment of the three-way connecting box 2 and the connecting sleeve 4, so that the grouting hole 7 is a semicircular cylindrical through hole formed by the side of the wallboard plate body 1 and the surface of another wallboard plate body 1;
