[0026] See also Figure 1 , in one embodiment, Figure 1 The corner connector 100 is provided in a composite wall panel 200 and is used to connect adjacent composite wall panels 200 at a corner of a room. The corner connector 100 includes a first splicing portion 10, a second splicing portion 20 and a fixing member 30. The first splicing portion 10 and the second splicing portion 20 have the same structure and are symmetrically arranged on both sides of the fixing member 30. The first splicing portion 10 and the second splicing portion 20 are respectively fixed to the corresponding composite wall panels 200. The fixing member 30 connects the first splicing portion 10 and the second splicing portion 20, thereby connecting the corresponding composite wall panels 200.

The side opposite to the side where the first groove 12 and the second groove 13 are located on the first body 11 is connected to the composite wallboard. The first groove 12, the second groove 13 and the third groove 14 are formed by one side of the first body 11 being recessed toward the opposite side thereof, and the first groove 12, the second groove 13 and the third groove 14 are used to hold the fixing member 30. In one embodiment, the two side walls of the third groove 14 are connected to the first body 11, one side is higher than the other side, and specifically, the side away from the second groove 13 is higher than the other side, so as to facilitate the smooth connection of the fixing member 30. In one embodiment, the cross section of the second groove 13 is approximately semicircular, so that the first joint portion 10 and the fixing member 30 are closely fitted, the cross sections of the first groove 12 and the third groove 14 are trapezoidal structures, and the cross section of the first body is approximately rectangular. In one embodiment, a sealing member is provided on the inner wall of the first groove 12, the second groove 13 and the third groove 14 to stabilize the connection effect with the fixing member 30. Figure 2 As shown, in one embodiment, the cross section of the third groove 14 can be set as a combination of a trapezoidal and a rectangular groove. It is understandable that the first groove 12 and the second groove 13 can also be selected as a combination groove according to actual needs to improve the connection stability. It is understandable that in order to increase the connection effect, some convex patterns that facilitate connection can also be set on the inner wall of the rectangular groove of the combined third groove 14, such as triangular prism protrusions arranged in sequence.

[0028] In one embodiment, in order to strengthen the connection effect with the composite wallboard, a reinforcing plate 15 is extended on one side of the first body 11 connected to the composite wallboard, and the number of the reinforcing plates 15 can be one or more. The position of the reinforcing plate 15 is not limited to being set at both ends of one side of the first body 11, and can be adjusted according to the structure of the composite wallboard so as to be clamped in the honeycomb panel and the face brick of the composite wallboard. In one embodiment, the reinforcing plate 15 is arranged on the reinforcing plate 15 and extends in a direction away from the side of the first body 11 where the first groove 12 is located. A plurality of ridges 151 are provided on the side of the first body 11 connected to the composite wallboard and on the reinforcing plate 15, and the ridges 151 are used to connect with the composite wallboard, and are clamped in the composite wallboard through the ridges 151, thereby stabilizing the connection relationship between the first splicing part 10 and the composite wallboard. A reinforcing rib 111 is provided in the first body 11 to strengthen the overall structure of the first splicing part 10, and one end of the reinforcing rib 111 is connected to the first body 11, and the other end is connected to the third groove 14. It is understandable that the number and connection positions of the reinforcing ribs 111 can be changed according to actual needs. In one embodiment, the first splicing portion 10 is integrally formed.

[0029] The structure of the second splicing portion 20 is completely the same as that of the first splicing portion 10 , and will not be described in detail herein.

The first fixing member 31 is provided with a second connecting plate 312 on one side opposite to the connecting plate 33. In one embodiment, the second connecting plate 312 is an arc-shaped connecting plate. Figure 4As shown, in one embodiment, when the two ends of the side where the first main body 11 is connected to the composite wall panel are extended with reinforcement plates 15, and the composite wall connection corner is used as a female angle, the second connecting plate 312 is further provided with a first supporting member 3112 on the side away from the first connecting plate 33, and the two ends of the first supporting member 3112 are respectively supported on the surface bricks of the composite wall panel, the first supporting member 3112 is an arc structure and is adapted to the arc of the second connecting plate 312, and the first supporting member 3112 is integrally formed with the first fixing member 31 or is bonded to the first fixing member 31.

[0032] The second fixing member 32 is provided with a second protrusion 321 and a third protrusion 322 on both sides adjacent to the first connecting plate 33, respectively. The shape of the second protrusion 321 matches the shape of the first groove 12, and the shape of the third protrusion 322 matches the shape of the second groove 13. The second protrusion 321 and the third protrusion 322 on both sides are used to be respectively clamped in the first groove 12 and the second groove 13 of the first splicing part 10 and the second splicing part 20, and the third connecting plate 323 is provided on the side of the second fixing member 32 opposite to the connecting plate 33.

In another embodiment, when the corner of the composite wall panel is used as a male angle, the third connecting plate 323 changes the original prismatic male angle into an arc-shaped structure, which is not easy to be injured in the event of a collision, and is both safe and beautiful.

[0034] The above-mentioned corner connector is provided with a first groove, a second groove and a third groove on the first splicing part and the second splicing part, and a corresponding first convex part, a second convex part and a third convex part are provided on the fixing part. The first convex part, the second convex part and the third convex part are clamped in the corresponding first groove, the second groove and the third groove to connect the corresponding first splicing part and the second splicing part, so that the corner connector can be used as not only a female corner connector but also a male corner connector.
