Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, an integrated multifunctional building exterior wall comprises a building exterior wall body 100, which includes right-angle panels 110 and flat standard panels 120. The horizontal ends of the right-angle panels 110 are perpendicularly arranged at 90 degrees. During on-site installation, the prefabricated building exterior wall construction only involves flat joints between standard panels 120, between standard panels 120 and right-angle panels 110, and between right-angle panels 110. This effectively reduces the number of joints in the prefabricated building exterior wall and avoids all corner joints, greatly reducing construction errors, avoiding potential cracking and leakage, and improving on-site construction efficiency.

[0033] like Figure 3As shown, the building exterior wall body 100 is provided with a thermal insulation and sound insulation layer 1 made of PU material, the indoor side of the thermal insulation and sound insulation layer 1 is provided with a 9mm thick fiber cement board 2, and the outdoor side is provided with a 12mm thick fiber cement board 2. A 1mm thick waterproof and breathable membrane 3 is also provided between the fiber cement board 2 on the outdoor side and the thermal insulation and sound insulation layer 1, which has the functions of waterproofing, heat preservation, sound insulation, fire prevention, etc., and effectively reduces the wall thickness, thereby improving the room ratio and reducing the wall's own weight, which can reduce the dependence on construction machinery during on-site installation and improve on-site construction efficiency.

[0034] like Figures 3 to 5 As shown, the top and bottom of the building exterior wall body 100 are respectively provided with a top keel 4 and a bottom keel 5 extending along the length thereof. Vertically extending side keels 6 are respectively provided at the horizontal ends of the building exterior wall body 100. The upper and lower ends of the side keels 6 are welded to the top keel 4 and the bottom keel 5, respectively. The top keel 4, the bottom keel 5, and the side keels 6 form a support frame, which effectively increases the strength of the building exterior wall body 100. In addition, a number of horizontally and vertically extending support keels are welded inside the support frame composed of the top keel 4, the bottom keel 5, and the side keels 6, further enhancing the support for the building exterior wall body 100.

[0035] like Figure 4 As shown, the two upper and lower adjacent building exterior wall bodies 100 are connected to the building body through an inverted T-shaped connecting member 7. The connecting member 7 is provided with a horizontal portion 8, and a vertical portion 9 is welded to the top of the horizontal portion 8. The vertical portion 9 is attached to the indoor side of the building exterior wall body 100 located above and is fixedly connected to one side of the bottom keel 5 of the building exterior wall body 100 through a first bolt 10. One end of the horizontal portion 8 extends between the two upper and lower adjacent building exterior wall bodies 100 and is fixedly connected to the top of the top keel 4 of the building exterior wall body 100 located below through a second bolt 11. The bottom keel 5 of the upper building exterior wall body 100 and the top keel 4 of the lower building exterior wall body 100 are embedded with each other, and the bottom of the bottom keel 5 of the upper building exterior wall body 100 is provided with a makeshift groove matching the head of the second bolt 11. The other end of the horizontal portion 8 is fixedly connected to the steel structure beam 13 of the building body through a third bolt 12, thereby effectively strengthening the connection strength between the building exterior wall body 100 and the building body.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the two side ribs 6 located at the horizontal ends of the building exterior wall body 100 are provided with mutually interlocking joint surfaces. During construction, the side ribs 6 of the two horizontally adjacent building exterior wall bodies 100 are directly interlocked, thereby improving the sealing between the building exterior wall bodies 100.

[0037] Example 2:

[0038] like Figure 6 and Figure 7 As shown, a connecting plate 14 is provided between two horizontally adjacent building exterior wall bodies 100. The connecting plate 14 is respectively interlocked with the side keels 6 on both sides along the length direction of the building exterior wall bodies 100. The indoor and outdoor sides of the connecting plate 14 are respectively provided with bonding plates 15. During assembly, after the two horizontally adjacent building exterior wall bodies 100 are interlocked with the connecting plate 14, the two bonding plates 15 are respectively covered on the indoor and outdoor sides of the connecting plate 14. At the same time, the bonding plates 15 cover the joints between the connecting plate 14 and the two building exterior wall bodies 100, further improving the sealing between the two building exterior wall bodies 100 and eliminating the risk of water leakage. In addition, a sealing pad layer is provided on the side of the bonding plate 15 close to the connecting plate 14 to further improve the sealing.

[0039] Two positioning posts 16 are provided along the length of the building exterior wall 100 on one side of the plywood 15 near the connecting plate 14. Sockets 17 for the positioning posts 16 are provided on the building exterior wall 100 on either side of the connecting plate 14. The sockets 17 extend through the edge keels 6 of the building exterior wall 100. When the plywood 15 is applied to the joint between the connecting plate 14 and the two building exterior wall assemblies 100, the two positioning posts 16 on the plywood 15 are inserted into the sockets 17 on the two building exterior wall assemblies 100, thereby improving the stability of the connection between the plywood 15 and the building exterior wall assemblies 100.

[0040] The two bonding plates 15 are locked by fastening bolts 18. The connecting plate 14 is a hollow tube extending vertically. A threaded tube 19 is vertically welded to one side of one bonding plate 15 close to the connecting plate 14. A first reserved hole 20 for the threaded tube 19 to pass through is provided on one side wall of the connecting plate 14. A mounting hole 21 for the fastening bolt 18 to pass through is provided on the other bonding plate 15. A second reserved hole 22 for the fastening bolt 18 to pass through is provided on the side wall of the connecting plate 14 away from the first reserved hole 20. The threaded end of the fastening bolt 18 passes through the mounting hole 21 and the second reserved hole 22 in turn and is screwed into the threaded tube 19, which fixes the connecting plate 14 and the bonding plates 15 on both sides of it, and at the same time enables the two connecting plates 14 to effectively clamp the building exterior wall body 100.
