The two ends of the first base part 21 are respectively inserted into the first connection groove 121 and the second connection groove 122, and the first connection part 22 is inserted into the third connection groove 123.

[0034] Specifically, the first connection groove 121 and the second connection groove 122 are symmetrically arranged. When two adjacent composite wall panels 1 are connected, there is a disconnection between the decorative panels 12 of the first composite wall panel 1 and the decorative panels 12 of the second composite wall panel 1. A third connection groove 123 is formed between the right side of the decorative panel 12 of the first composite wall panel 1 and the left side of the decorative panel 12 of the second composite wall panel 1. The first connection groove 121, the second connection groove 122, and the third connection groove 123 are all rectangular grooves. The first connection groove 121 and the second connection groove 122 are respectively connected to the third connection groove 123, thereby forming a first installation groove 15, and the first installation groove 15 can be a T-shaped groove. The left and right ends of the first base 21 are respectively inserted into the first connection groove 121 of the first composite wall panel 1 and the second connection groove 122 of the second composite wall panel 1. The first connection part 22 is vertically connected to the first base 21, so that the waterproof strip 2 is a T-shaped structure, and the first connection part 22 abuts against the decorative panels 12 of two adjacent composite wall panels 1.

[0035] The first socket structure 13 may further include a first clamping strip 132 provided on the side surface of the first connection plate 131 close to the wall body 4. The second socket structure 14 may further include a first clamping groove 144 provided on the side surface of the second connection plate 141 away from the wall body 4 and communicating with the second socket groove 143. The first clamping strip 132 is clamped in the first clamping groove 144.

[0036] Specifically, the first clamping strip 132 is clamped in the first clamping groove 144, which improves the connection stability between the first socket structure 13 and the second socket structure 14.

[0037] The first socket structure 13 may further include a first groove 134 provided on the side surface of the first connection plate 131 close to the wall body 4. The second socket structure 14 may further include a second groove 145 provided on the side surface of the second connection plate 141 away from the wall body 4. The first groove 134 and the second groove 145 are connected to form a drain groove 16.

[0038] Specifically, there may be two first grooves 134 and two second grooves 145. The two first grooves 134 and the two second grooves 145 are connected to form two drain grooves 16. The drain groove 16 may be a through-length drain groove. The arrangement of the drain groove 16 enables the built-in drainage structure at the joint of the base plates 11, which can further improve the waterproof performance, form two waterproof structures, prevent the water vapor and water flow of the decorative panel 12 from infiltrating into the inner side of the composite wall panel 1, and can be discharged externally to avoid the overall device from getting damp.

[0039] As an assembled bathroom wall waterproof installation device in this embodiment, it may further include a first fastening part 3 for detachably connecting at least one of the base plate 11, the first connection plate 131, and the second connection plate 141 to the wall body 4.

[0040] On the side of the second connecting plate 141 away from the wall body 4, a first fixing groove 142 can be recessed. One end of the first fastening part 3 sequentially passes through the first fixing groove 142 and the second connecting plate 141 and is fixedly connected to the wall body 4, and the other end of the first fastening part 3 is arranged in the first fixing groove 142.

[0041] Specifically, the other end of the first fastening part 3 is arranged in the first fixing groove 142 to prevent the first fastening part 3 from affecting the insertion of the first connecting plate 131 of another composite wall panel 1 into the second insertion groove 143.

[0042] The first connecting groove 121 can be recessed and arranged at one end of the left side of the decorative panel 12 close to the first connecting plate 131, and the second connecting groove 122 is recessed and arranged at one end of the right side of the decorative panel 12 close to the second connecting plate 141. One side of the first base part 21 away from the first connecting part 22 abuts against the first connecting plate 131 and the second connecting plate 141 respectively.

[0043] Specifically, the cross-sectional area of the first base part 21 is arc-shaped. After the decorative panels 12 of two composite wall panels 1 are assembled, a first installation groove 15 is formed, and a waterproof strip 2 with an EPDM inner embedding material and a circular arc cross-section is embedded, which is not only convenient for embedded installation to form a complete waterproof structure, but also has good waterproofness and weather resistance, and prevents the waterproof strip 2 from oxidizing and deforming, resulting in a decline in waterproof performance.

[0044] The base board 11 can be a stone plastic base board, the decorative panel 12 is a ceramic tile, and the waterproof strip 2 is an EPDM waterproof strip.

[0045] Specifically, the composite wall panel 1 is composed of a stone plastic base board with good waterproof performance and a ceramic tile. The EPDM waterproof strip is an ethylene propylene diene monomer sealing strip, that is, an ethylene propylene diene monomer rubber strip. The first connecting groove 121 and the second connecting groove 122 are respectively cut at both ends of the side of the ceramic tile close to the wall surface. After two adjacent composite wall panels 1 are installed, the EPDM waterproof strip is filled between the two ceramic tiles to form a complete wall surface waterproof structure; both ends of the composite wall panel 1 have a first socket structure 13 and a second socket structure 14 with a relatively long structure, which improves the connection strength and structural stability of the composite wall panel 1; the first socket structure 13 and the second socket structure 14 are connected to form a through-long drainage groove. If water vapor seeps in due to improper installation, it can be discharged in time to ensure that it will not leak into the structure of the wall body 4, the structure is reliable, and there is no need to construct a waterproof layer on the surface of the wall body 4 in advance.
