[0032] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0033] like Figure 1 and 2As shown in one embodiment of this utility model, the prefabricated building wall includes an outer protective panel 1, a fastening body 2, a limiting body 3, and an inner protective layer 4. The inner protective layer 4 is connected to the interior of the outer protective panel 1. At least one first mounting groove 101 and at least one second mounting groove 102 are provided between the inner protective layer 4 and the outer protective panel 1. The first mounting groove 101 and the second mounting groove 102 are arranged opposite to each other on both sides of the inner protective layer 4. One end of the fastening body 2 is connected to the second mounting groove 102. The fastening body 2 is provided with a fastening groove 21. The limiting body 3 includes a limiting plate 31 and an elastic member 32. One end of the elastic member 32 is connected to the interior of the first mounting groove 101. The other end of the elastic member 32 is connected to the limiting plate 31. In two adjacent outer protective panels 1, the limiting plate 31 is limited and connected to the interior of the fastening groove 21. Furthermore, the first mounting groove 101 and the second mounting groove 102 can be set at the upper and lower ends or the left and right ends of the prefabricated building wall; that is, in order to realize the horizontal and vertical assembly of the prefabricated building wall, the fastening body 2 and the limiting body 3 are respectively set at the upper and lower ends and the left and right ends of the prefabricated building wall.

[0034] The technical solution of this utility model, through the flexible adjustment performance of the elastic compression position and the recovery position of the limiting plate, can quickly and flexibly achieve the assembly of the limiting plate and the limiting body, and ensure the assembly stability between two adjacent outer protective panels; it also achieves the concealed performance of the assembly of the limiting plate and the limiting body through the first mounting groove and the second mounting groove, thereby improving the assembly flatness between two adjacent outer protective panels and ensuring the stability and aesthetic performance of the assembly; in addition, the outer protective panel and the inner protective layer can improve the structural stability of the environmentally friendly wall for building construction and extend its service life.

[0035] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the fastening body 2 includes a vertical connecting block 21, a horizontal connecting block 22, and a first support block 23 connected in sequence; the vertical connecting block 21 and the horizontal connecting block 22 are inclined and form the fastening groove 21; the first support block 23 is connected to the interior of the second mounting groove 102; the adjacent side surfaces of the limiting plate 31 abut against the vertical connecting block 21 and the horizontal connecting block 22 respectively. In other words, the formed L-shaped fastening structure allows for convenient and flexible assembly and ensures assembly stability. For example, Figure 2As shown, the bottom of the vertical connecting block 21 is provided with a guide arc surface 211; the guide arc surface 211 is convexly arc-shaped towards the limiting plate 31. That is to say, during the assembly process, the guide arc surface 211 of the vertical connecting block 21 first contacts and guides the limiting plate 31 to reduce the impact between the two and increase the assembly speed.

[0036] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the fastening body 2 further includes a first positioning rod 24; one end of the first positioning rod 24 passes through the outer protective panel 1 and is detachably connected to the first support block 23. Wherein, as... Figure 2 and 3 As shown, the first support block 23 has an assembly hole 231; the first positioning rod 24 is detachably connected to the outer protective panel 1 and the assembly hole 231 respectively by means of threads. Further, when the environmental protection wall is not the last piece to be assembled, one end of the first support block 23 abuts against the inner protective layer 4 (the abutting form can reduce the shaking phenomenon of the first support block 23 and improve the assembly stability). When the environmental protection wall is the last piece to be assembled, there is an installation gap between the first support block 23 and the inner protective layer 4. By driving the first positioning rod 24, the first support block 23, the vertical connecting block 21 and the horizontal connecting block 22 are hidden in the second mounting groove 102 (at this time, the space of the second mounting groove 102 is adjusted according to the actual situation to ensure that the vertical connecting block 21 and the horizontal connecting block 22 can be hidden). Then, the two adjacent outer protective panels 1 are assembled side by side. Immediately afterwards, the first positioning rod 24 is rotated so that the vertical connecting block 21 and the horizontal connecting block 22 are directly engaged on the limiting plate 31.

[0037] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 4, the elastic component 32 includes a spring 321 and a second support block 323 connected to each other; and the second support block 323 is connected to the first mounting groove 101; one end of the spring 321 is connected to the limiting plate 31.

[0038] Specifically, in some implementations, such as Figure 4 As shown, the elastic component 32 further includes a second positioning rod 322; one end of the second positioning rod 322 passes through the outer protective panel 1 and is detachably connected to the second support block 323. Wherein, as Figure 2 and 4 As shown, the second support block 323 has a mounting hole; the second positioning rod 322 is detachably connected to the outer protective panel 1 and the mounting hole by means of threads.

[0039] Specifically, in some implementations, such as Figure 2 and 4 As shown, a push rod 324 is provided at the bottom of the limiting plate 31; one end of the push rod 324 is connected to a traction rod 325; one end of the traction rod 325 passes through the thickness direction of the outer protective panel 1. That is, by pushing the traction rod 325 downward, the push rod 324 and the limiting plate 31 are pulled towards the spring 321 for compression, so as to separate the limiting plate 31 from the fastening body 2, thereby separating the two adjacent outer protective panels 1.

[0040] Specifically, in some implementations, such as Figure 1 and 5 As shown, the outer protective panel 1 includes a first supporting wall panel 11 and a second supporting wall panel 12; the first supporting wall panel 11, the inner protective layer 4, and the second supporting wall panel 12 are stacked sequentially; and the fastening body 2 is connected to the first supporting wall panel 11 and / or the second supporting wall panel 12; the limiting body 3 is connected to the first supporting wall panel 11 and / or the second supporting wall panel 12. The first supporting wall panel 11 and / or the second supporting wall panel 12 are made of fiber-reinforced cement wallboard or lightweight partition wallboard (which has lightweight and good sound insulation performance) or wood-plastic composite wallboard (which has waterproof, anti-corrosion, and insect-proof characteristics).

[0041] Specifically, in some implementations, such as Figure 1 and 5 As shown, the inner protective layer 4 includes a first insulation layer 41, a first mesh frame 42, a sound insulation layer 43, a second mesh frame 44, and a second insulation layer 45 stacked sequentially. In some embodiments, the first insulation layer 41, the first mesh frame 42, the sound insulation layer 43, the second mesh frame 44, and the second insulation layer 45 are arranged sequentially along the direction from the first supporting wall panel 11 towards the second supporting wall panel 12. Further, the first mesh frame 42 and the second mesh frame 44 are both metal mesh frames (like a grid structure) formed by sequentially arraying and interlacing horizontal metal rods and vertical metal rods. Further, the first insulation layer 41 is made of rock wool or phenolic resin; the second insulation layer 45 is also made of rock wool or phenolic resin, to achieve characteristics such as high temperature resistance, relatively low weight, and non-combustibility. Further, the sound insulation layer 43 is made of corrugated sound-absorbing sponge or polyester fiber sound-absorbing board to achieve high sound insulation performance and relatively low weight.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
