[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a BIM-based modular exterior wall includes a modular exterior wall body 5, wherein there are multiple modular exterior wall bodies 5, one side of each of the multiple modular exterior wall bodies 5 is connected with a stirrup 7, and the outer side of each of the multiple modular exterior wall bodies 5 is connected with a cast-in-place structure outer ring beam 2. The stirrups 7 can improve the strength of the connection between the cast-in-place structure outer ring beam 2 and the modular exterior wall body 5, thereby improving the stability of the entire building. At the same time, the stirrups 7 are located inside the cast-in-place structure outer ring beam 2, and the upper surface of the cast-in-place structure outer ring beam 2 is connected with a cast-in-place floor slab 1. A shear groove 8 is provided on the inner side of the modular exterior wall body 5, and the shear groove 8 can evenly disperse the lateral shear load, increase the strength and stability of the connection part, and improve the service life and reliability of the exterior wall components. The inner wall of the modular exterior wall body 5 is detachably connected with an embedded window frame 6.

[0022] The top of the modular exterior wall body 5 is consistent with the elevation of the cast-in-place floor 1. A horizontal splicing seam 3 is formed at the connection of multiple modular exterior wall bodies 5, and a vertical splicing seam 4 is formed at the same time. The inner side of the modular exterior wall body 5 is connected with an XPS weight-reducing block 10. The vertical splicing seam 4 and the horizontal splicing seam 3 generated by the splicing of multiple modular exterior wall bodies 5, and the internal connection of the vertical splicing seam 4 and the horizontal splicing seam 3 generate a cavity 13. PE rods 11 are provided inside the cavity 13. The outside of the PE rod 11 is connected with a weather-resistant glue 12. At the same time, the weather-resistant glue 12 is connected to one side of the modular exterior wall body 5. The PE rods 11 and weather-resistant glue 12 reduce the risk of leakage and improve the sealing between the vertical splicing seams 4 and the horizontal splicing seams 3. The XPS weight-reducing blocks 10 are located inside the columns on both sides of the modular exterior wall body 5, which can reasonably and effectively reduce the weight of the modular exterior wall body 5 and improve the lifting efficiency. The waterproof method of assembling the modular exterior wall body 5 from top to bottom mainly involves inserting the PE rods 11 from the outside and then injecting the weather-resistant glue 12 into the gap to play a role in material waterproofing. The cavity 13 reserved in the middle section also plays a role in structural waterproofing. The double waterproofing measures reduce the risk of leakage of the modular exterior wall body 5.

[0023] A prefabricated component 9 is provided at the bottom end of the modular exterior wall body 5, and a steel sheet 20 is connected to the interior of the prefabricated component 9. Mortar 14 is connected between the modular exterior wall body 5 and the steel sheet 20. After the steel sheet 20 is connected, the mortar 14 is filled at the position of the prefabricated component 9 to limit the internal components and improve the stability of the internal components of the prefabricated component.

[0024] The interior of the cast-in-place floor slab 1 is connected with an embedded steel plate 15, the inner side of the steel sheet 20 is penetrated and connected with a threaded steel bar 21, and the outer side of the threaded steel bar 21 is penetrated and connected with an L-shaped angle steel 17. The other end of the L-shaped angle steel 17 is connected to the embedded steel plate 15. The embedded steel plate 15 and the L-shaped angle steel 17 are welded together. After welding, a weld 16 is generated at the connection. The embedded steel plate 15 is placed in the interior of the modular exterior wall body 5 in advance at the component factory. When installing the modular exterior wall of this layer, the bottom embedded steel plate 15 of the modular exterior wall body 5 is penetrated with the threaded steel bar 21, and the L-shaped angle steel is inserted. 17 is put on the threaded steel bar 21. After the modular exterior wall body 5 is hoisted, the L-shaped angle steel 17 is connected to the embedded steel plate 15. The L-shaped angle steel 17 is connected and fixed to the embedded steel plate 15 by welding. The welding connection method is more stable. The outside of the threaded steel bar 21 is connected with a gasket 18, and one end of the threaded steel bar 21 is threaded with a nut 19. Now add the gasket 18 and put it on the threaded steel bar 21, and then add the nut 19 to fix it. Finally, cut off the threaded steel bar 21 that exceeds the outside of the modular exterior wall body 5. After completion, the bottom limit connection is made.

[0025] It should be noted that in actual use of the device, the modular exterior wall body 5 is first hoisted to the designated position, and then the outer ring beam 2 of the cast-in-place structure is connected to the stirrups 7, and then the cast-in-place floor slab 1 is connected to the outer ring beam 2 of the cast-in-place structure, and at the same time the L-angle steel and the embedded steel plate 15 are connected together, and then the threaded steel bar 21 is passed through the steel sheet 20 and the L-shaped angle steel 17, and then the gasket 18 is put on the threaded steel bar 21, and then the nut 19 is turned to lock the L-shaped angle steel 17.
