The second connector 5 is fitted into two sets of connecting grooves between two adjacent sets of partition wall bodies 1 at the edge of the partition wall. Both the first connector 3 and the second connector 5 have multiple sets of first storage slots 303 and first insertion holes 304. The first storage slots 303 and the first insertion holes 304 are connected. The first insertion holes 304 correspond to the second insertion holes 404 on the partition wall body 1. The fastener 405 passes through the second insertion hole 404 and the first insertion hole 404. Hole 304 is used for fixing, the second storage groove 403 is used to store nuts, and the first storage groove 303 is used to store nuts on bolts, so as to avoid the end of fastener 405 protruding and affecting the flatness of the partition wall body 1. Both the first storage groove 303 and the second storage groove 403 are provided with a chamfer structure at the groove opening, with a chamfer angle of 45°-60°, which facilitates the installation and removal of fastener 405.

[0018] In this embodiment, firstly, based on the design dimensions of the partition wall, the number and arrangement of the partition wall bodies 1 are determined. At the center, the cross-shaped locking seat 301 and four sets of straight-line seats 302 of the first connector 3 are correspondingly fitted into the connecting grooves at the corners of the four adjacent partition wall bodies 1, namely the horizontal groove 4, the first vertical groove 401, and the second vertical groove 402. At the edge, the mountain-shaped locking seat 301 and the corresponding straight-line seat 302 of the second connector 5 are fitted into the connecting grooves at the corners of the two adjacent partition wall bodies 1. Aligning the first insertion holes 304 on the first connector 3 and the second connector 5 with the second insertion holes 404 on the partition wall body 1, the bolts of the fasteners 405 are sequentially inserted through the second insertion holes. The nuts are installed and tightened in the second storage groove 403 of the hole 404 and the first insertion hole 304, so that the bolt nuts are stored in the first storage groove 303, thus completing the connection and fixation of the partition wall body 1. After all the partition wall bodies 1 are connected and fixed, environmentally friendly glue is applied to the surface of the second base plate 104 on the outside of the partition wall body 1, and the two sets of surface plates 2 are respectively glued to both sides of the partition wall to complete the assembly of the entire prefabricated building residential partition wall. When a partition wall body 1 is damaged, the corresponding surface plate 2 is removed first, then the fastener 405 at the connection position of the partition wall body 1 is unscrewed, the damaged partition wall body 1 is taken out, a new partition wall body 1 is replaced, and then the fastener 405 and surface plate 2 are reinstalled.

[0019] Example 2, as Figure 6As shown, the prefabricated partition wall for residential buildings proposed in this utility model, compared with Embodiment 1, the partition wall body 1 is composed of a light steel keel frame 101, a first base plate 102 and a second base plate 104. Two sets of first base plates 102 are symmetrically installed on the outer side of the light steel keel frame 101 by screws. The cavity formed between the two sets of first base plates 102 and the light steel keel frame 101 is filled with a sound insulation layer 103. The outer side of each set of first base plates 102 is bonded with a second base plate 104, and the outer side of the second base plate 104 is bonded to the surface plate 2.

[0020] Furthermore, the light steel keel frame 101 is made of galvanized light steel keel to improve the overall strength of the partition wall body 1, the first base board 102 is made of water-resistant gypsum board to provide structural strength and basic moisture-proof performance, the sound insulation layer 103 is made of rock wool to improve the sound insulation effect, and the second base board 104 is made of high-density cement fiber board to further improve the moisture-proof performance.

[0021] In this embodiment, the light steel keel frame 101 serves as the core supporting structure, providing sufficient load-bearing capacity; the first base plates 102 on both sides together with the light steel keel frame 101 form the basic frame, enhancing the overall rigidity of the partition wall body 1; the sound insulation layer 103 filled in the middle cavity effectively absorbs sound waves using the porous structure of rock wool, reducing sound transmission and improving the sound insulation performance of the partition wall; the second base plate 104 on the outer side further enhances the moisture-proof performance of the partition wall, preventing the damp environment from damaging the internal structure of the partition wall.
