[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories are processed and manufactured, then transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] In the existing prefabricated building structure system, two prefabricated wall panels that are perpendicular to each other are usually connected by a connection box. In order to ensure the connection strength, multiple connection boxes need to be arranged in the vertical direction at the end face of a prefabricated wall panel. When there is a height deviation between the two prefabricated wall panels that are perpendicular to each other, since the installation position of the connection box has been arranged in advance, the position of the connection box cannot be adjusted, and the position of the prefabricated wall panel cannot be adjusted. The two prefabricated wall panels may not be completely abutted, resulting in a large gap, which affects the appearance and waterproof performance of the prefabricated building.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] See also Figures 1 to 8 An embodiment of the present invention provides a prefabricated wall panel connection node for quickly connecting a first prefabricated wall panel 1 and a second prefabricated wall panel 2 that are perpendicular to each other. The prefabricated wall panel connection node includes two mutually perpendicular connecting plates 3 and an L-shaped connector. One end of one connecting plate 3 is inserted into the first prefabricated wall panel 1, and one end of the other connecting plate 3 is inserted into the second prefabricated wall panel 2. The two ends of the L-shaped connector 4 are respectively connected to the other ends of the two connecting plates 3.

[0026] The first prefabricated wall panel 1 and the second prefabricated wall panel 2 are provided with grooves 10 matching the size of the connecting plate 3 on the end faces. After the connecting plate 3 is inserted into the groove 10 in the first prefabricated wall panel 1 and the second prefabricated wall panel 2, cement mortar is injected into the groove 10. After the cement mortar solidifies, the two connecting plates 3 are fixedly connected to the first prefabricated wall panel 1 and the second prefabricated wall panel 2 respectively.

[0027] In one embodiment of the present invention, the portion of the connection plate 3 inserted into the first prefabricated wall 1 and the second prefabricated wall 2 is provided with an array of circular holes 5, and the circular holes 5 are arranged in a 2×3 array.

[0028] After the cement mortar enters the circular holes 5 of the array and solidifies, the fixing strength of the connecting plate 3 can be improved.

[0029] After being fixedly connected with the first prefabricated wall panel 1 and the second prefabricated wall panel 2, the two connecting plates 3 are in mutually perpendicular positions, and after the two mutually perpendicular surfaces of the L-shaped connecting piece 4 are respectively connected with the two connecting plates 3, the assembly of the first prefabricated wall 1 and the second prefabricated wall 2 is realized.

[0030] In one embodiment of the present invention, the connecting portion of the connecting plate 3 and the L-shaped connecting member 4 is respectively provided with an array of long holes 7, the length directions of the long holes 7 on the connecting plate 3 and the long holes 7 on the L-shaped connecting member 4 are perpendicular to each other, and bolts 8 are connected in the long holes 7. Gaskets 9 are passed through both ends of the bolt 8, and the gaskets 9 at both ends are respectively abutted against the connecting plate 3 and the L-shaped connecting member 4.

[0039] S4: Use bolts 8 to connect the other end of the L-shaped connecting piece 4 to another connecting plate 3 .

[0040] S5: Use the bolts 8 and the long holes 7 to adjust the relative positions of the L-shaped connecting member 4 and the two connecting plates 3 until the first prefabricated wall panel 1 and the second prefabricated wall panel 2 are in place.

[0041] S6: Tighten all bolts 8.
