For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 5 This application provides a prefabricated sandwich panel composite wall system with precast keel, including a central partition 1. A module assembly 2 is provided on one side of the central partition 1. The module assembly 2 includes a top plate 21, which is fixedly connected to the top and bottom of the central partition 1. A groove 23 is provided inside the top plate 21, and a wall panel 24 is slidably connected to the inner wall of the groove 23. An insertion hole 25 is provided on one side of the top plate 21. A reinforcing strip 22 is fixedly connected to one side of the central partition 1. The module assembly 2 also includes a side plate 27, and a positioning rod 29 is fixedly connected to one side of the side plate 27. One end of the positioning rod 29 is inserted into the insertion hole 25. An installation groove 28 is provided inside the side plate 27, and a bolt 26 is threadedly connected inside the side plate 27. The bolt 26 is entirely located inside the installation groove 28, and one end of the bolt 26 is also threadedly connected to the inside of the top plate 21.

[0031] In practice: the wall panel 24 is slid into the groove 23, and the reinforcing strip 22 is used to improve the impact resistance of the wall panel 24. Then, the positioning rod 29 on one side of the side panel 27 can be inserted into the socket 25 to complete the positioning of the side panel 27. Then, the side panel 27 can be fixed to the bracket of the top plate 21 by bolts 26. Since the fixing method does not use welding, the whole adopts a modular design. If one of the wall panels 24 is damaged, the side panel 27 can be quickly disassembled and replaced, saving time and effort.

[0032] Reference Figures 1 to 5 In one aspect of this embodiment, sound-absorbing cotton is filled between every two reinforcing strips 22. The wall panel 24 is made of fiber cement board.

[0033] In specific implementation: sound insulation cotton is filled between every two reinforcing strips (22 strips). The sound insulation cotton mainly reduces noise by absorbing sound energy, reducing sound wave reflection and vibration transmission. Fiber cement board is a new type of building board made of cement as the base material, with the addition of cellulose fiber, mineral fillers and other materials, and is made through pulping, molding and curing processes. It has the advantages of high strength and durability, outstanding fire resistance, and excellent waterproof and moisture-proof performance.

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working principle: During installation, the wall panel 24 is first precisely slid into the groove 23. The reinforcing strip 22 is made of high-strength alloy material, effectively enhancing the wall panel's impact resistance. After the wall panel is in place, the positioning rod 29 on one side of the side panel 27 is aligned with the insertion hole 25 on the wall panel 24 and inserted vertically to complete the initial positioning. Subsequently, bolts 26 are used to secure the side panel 27 to the top panel 21. This modular, non-welded design significantly improves the maintainability of the structure. When a wall panel 24 is damaged, the damaged part can be quickly replaced simply by disassembling the side panel 27, significantly improving maintenance efficiency.

[0036] In terms of sound insulation and noise reduction, high-performance sound insulation cotton is evenly filled between every two reinforcing strips 22. This sound insulation cotton utilizes a porous structure to effectively reduce noise transmission through multiple mechanisms, including absorbing sound energy, reducing sound wave reflection, and blocking vibration transmission. The wall panel 24 uses fiber cement board, which is made with silicate cement as the binder, incorporating refined cellulose fibers and natural mineral fillers, and manufactured through advanced processes such as pulping, molding, and high-pressure curing. This new type of building material not only possesses excellent strength and durability but also boasts superior fire-retardant properties, along with good waterproof and moisture-proof capabilities, enabling it to adapt to complex and ever-changing building environments.
