The sandwich prefabricated wall includes multiple vertical purlins 3, multiple plug-in components 4, and multiple sound insulation panels. The multiple vertical purlins 3 are spaced apart in the first direction and include two first purlins 11 and multiple second purlins 12. The multiple second purlins 12 are located between the two first purlins 11 and spaced apart in the first direction. The first purlins 11 include a first base plate 14 and two first side plates 15 located at opposite ends of the first base plate 14 in the second direction. The first base plate 14 of one of the two first purlins 11 is connected to the head wall 1, while the first base plate 14 of the other first purlin 11 is connected to the tail wall 2. The first base plate 14 is provided with a first clip 16 and a first through-hole corresponding to the first clip 16. The first clip 16 and the two first side plates 15 are located on the same side of the first base plate 14 in the first direction. The first clip 16 and the first through-hole are formed by cutting and bending the sheet material of the first base plate 14. The second direction is perpendicular to the first direction. The second keel 12 includes a second base plate 17, which is equipped with multiple second clips 19 and at least one third clip 20. The multiple second clips 19 are located on one side of the second base plate 17 in the second direction, with at least two second clips 19 spaced apart in the second direction. The space between the two second clips 19 in the second direction forms a first retaining groove 21. At least one third clip 20 is located on the other side of the second base plate 17 in the second direction. The second base plate 17 has a second through-hole corresponding to the third clip 20. The third clip 20 and the second through-hole are formed by cutting and bending the sheet material of the second base plate 17. The multiple plug-in components 4 include multiple first plug-in components 9 connected to the first keel 11 and multiple second plug-in components 10 connected to the second keel 12. The first plug-in components 9 are locked in the first through-holes. The first plug-in components 9 are located on the side of the first base plate 14 with the first clip 16 in the first direction and are spaced apart from the first clip 16 in the second direction. The second retaining groove 22 is formed between the first plug-in components 9 and the first clip 16. The second plug-in member 10 is buckled into the second through-hole. The second plug-in member 10 is located on the side of the second base plate 17 with the third clip 20 in the first direction and is spaced apart from the third clip 20 in the second direction, forming a third retaining groove 23 between the second plug-in member 10 and the third clip 20. The multiple sound insulation panels include a plurality of intermediate panels 6 arranged sequentially in the first direction. An intermediate panel 6 is provided between adjacent vertical purlins 3. One end of the intermediate panel 6, located between the first purlin 11 and the second purlin 12, is inserted into the first retaining groove 21, and the other end is inserted into the second retaining groove 22 or the third retaining groove 23. The sandwich prefabricated wall of this example features a small number of components, low cost, and excellent sound insulation. The purlins used therein do not require multiple folding and cold bending processes, saving processing costs. Furthermore, the sandwich prefabricated wall of this example solves the problem of seamless assembly from beginning to end, achieving tight assembly without gaps, simple process, and fast and efficient construction.

[0022] In some exemplary embodiments, Figures 1 to 5 As shown, the head wall 1 and the tail wall 2 are spaced apart in a first direction, and the wall surfaces of both the head wall 1 and the tail wall 2 are perpendicular to the first direction. The first direction can be parallel to the ground, the second direction can be perpendicular to the first direction and parallel to the ground, and the third direction can be perpendicular to the ground, i.e., a vertical direction, perpendicular to both the first and second directions. The vertical purlins 3 extend along the third direction and can be fixed to the upper and lower floor slabs at both ends of the third direction, fixing the position of the vertical purlins 3 and forming the framework of the wall.

[0023] In some exemplary embodiments, Figures 1 to 5 As shown, the sound insulation panels can be plate-shaped and perpendicular to the second direction, that is, they stand upright and extend along the first direction. The thickness of the sound insulation panels can be the dimension of the sound insulation panels in the second direction. In addition to the intermediate panel 6, the multiple sound insulation panels also include multiple first sound insulation panels 7 and multiple second sound insulation panels 8. The first and second sound insulation panels 7, 8 are positioned on either side of the multiple vertical purlins 3 in the second direction, with the intermediate panel 6 positioned between the first and second sound insulation panels 7, 8, forming a three-layer sound insulation structure that enhances sound insulation. The intermediate panel 6, first and second sound insulation panels 7, 8 are made of the same material, which can be gypsum board, calcium silicate board, cement board, damping composite board, composite wood board, fiber composite board, metal composite board, sound-insulating and sound-absorbing board, or ceramic board.

[0024] In some exemplary embodiments, Figures 1 to 5 As shown, the sandwich prefabricated wall also includes sound insulation and thermal insulation material 5, which is located between the first sound insulation board 7 and the intermediate board 6, and between the second sound insulation board 8 and the intermediate board 6. The sound insulation and thermal insulation material 5 fills the space between the first sound insulation board 7 and the intermediate board 6, and between the second sound insulation board 8 and the intermediate board 6, to ensure sound insulation and thermal insulation performance. Thus, in addition to the three layers of sound insulation boards mentioned above, two layers of filling material are added, further improving the sound insulation and thermal insulation of the wall.

The first keel 11 includes the first bottom plate 14 and the first side plate 15. The first bottom plate 14 and the first side plate 15 are perpendicular to each other, forming a U-shape. The first bottom plate 14 is provided with a first groove 24, the notch of the first groove 24 facing away from the side of the first bottom plate 14 with the first side plate 15 in the first direction.

[0026] In some exemplary embodiments, Figure 6 and Figure 7As shown, the first base plate 14 is provided with a plurality of first through holes 26. These first through holes 26 may be rectangular holes and are evenly spaced in the third direction. The wall of each first through hole 26 closest to the lower floor in the third direction may be a first edge 28. These first through holes 26 are centrally located on the first base plate 14 and are disposed at the bottom of the first groove 24.

[0027] In some exemplary embodiments, Figure 6 and Figure 7 As shown, the first through hole 26 can be formed during the process of cutting and bending the first base plate 14 to form the first clip 16. Specifically, a U-shaped cutout is formed at the cutout of the first base plate 14, and the sheet surrounded by the U-shaped cutout is bent to form the first clip 16. The first through hole 26 is formed in the original position of the sheet that formed the first clip 16. One end of the first clip 16 is connected to the hole wall of the first through hole 26 at one end in the second direction.

[0028] In some exemplary embodiments, Figure 6 and Figure 7 As shown, the first clip 16 may include a third segment 29 and a fourth segment 30. One end of the third segment 29 is connected to the first base plate 14, and the other end is connected to the fourth segment 30. The end of the third segment 29 facing away from the first base plate 14 is inclined in the second direction toward the side closer to the second edge 27, rendering the third segment 29 non-perpendicular to the first base plate 14. The angle between the third segment 29 and the first base plate 14 may range from 60° to 85°. The end of the fourth segment 30 facing away from the third segment 29 is inclined in the second direction toward the side farther from the second edge 27, rendering the third segment 29 and the fourth segment 30 at an angle. The angle between the third segment 29 and the fourth segment 30 may range from 130° to 175°. A protrusion 42 is formed at the junction of the third segment 29 and the fourth segment 30. The first clip 16 extends a length L2 in the first direction, and the maximum distance between the first clip 16 and the first side plate 15 in the second direction is L1.

A first gap 25 is formed between the bottom of the first groove 24 and the head end wall 1, providing space for the installation of subsequent plug-ins. The first base plate 14 of the first keel 11 can be fixed to the head end wall 1 using expansion bolts. The first side plate 15 of the first keel 11 is located on the side of the first base plate 14 facing away from the head end wall 1. The opposing end surfaces of the two first side plates 15 can be respectively attached to the first sound insulation board 7 and the second sound insulation board 8, and connected by fasteners 13.

[0032] In some exemplary embodiments, Figures 8 to 12As shown, the plurality of second clamping plates 19 include a plurality of first flaps 31 and a plurality of second flaps 32. The first flaps 31 and the second flaps 32 are spaced apart in the second direction and alternately arranged in the third direction. The space between the first flaps 31 and the second flaps 32 in the second direction forms a first limiting groove 21. The first limiting groove 21 extends along the third direction, with the notch of the first limiting groove 21 facing away from the side of the second base plate 17 having the second side plate 18. The distance between the first flaps 31 and the second flaps 32 can be L3, where the vertical length of L3 can be equal to the thickness of the intermediate plate.

The end of the sixth plate segment 41 distal to the fifth plate segment 40 may be inclined in the second direction toward the side distal to the second edge 27, such that the fifth plate segment 40 and the sixth plate segment 41 are arranged at an angle. The angle between the fifth plate segment 40 and the sixth plate segment 41 may be between 130° and 175°. A protrusion 42 is formed at the junction of the fifth and sixth plate segments 40 and 41.

[0034] In some exemplary embodiments, Figures 8 to 12As shown, the second clamping plate may include a first plate segment 38 and a second plate segment 39. For example, the first flap 31 may include a first plate segment 38 and a second plate segment 39. One end of the first plate segment 38 is connected to the hole wall of the fourth through hole 35 of the second base plate 17 at one end in the second direction, and the other end is connected to the second plate segment 39. The end of the first plate segment 38 distal to the second base plate 17 is inclined toward the other end of the fourth through hole 35 in the second direction, such that the first plate segment 38 is non-perpendicular to the second base plate 17.

For another example, the second flap 32 may include a first plate segment 38 and a second plate segment 39. One end of the first plate segment 38 is connected to the hole wall of the third through hole 34 of the second base plate 17 at one end in the second direction, and the other end is connected to the second plate segment 39. The end of the first plate segment 38 away from the second base plate 17 is inclined in the second direction toward the other end of the third through hole 34 in the second direction, so that the first plate segment 38 is non-perpendicular to the second base plate 17, and the angle between the first plate segment 38 and the second base plate 17 can be 60° to 85°.
