[0037] The present invention also provides a method for constructing a standardized SPCS cavity wall assembly system, which is carried out according to the following steps: S1: The load-bearing parameters and component sizes of each standardized SPCS cavity wall are decomposed according to the building design indicators, and BIM modeling is carried out using REVIT 3D software to form a standardized SPCS cavity wall construction and assembly system; S2: Based on the BIM model, simulation is carried out and materials, structures and dimensions that do not meet the requirements are modified, and then simulation is repeated until the standard requirements are met; S3: Extracts BIM model data and generates drawings of individual parts and specific construction steps. Construction equipment uses the BIM model database to fully analyze the 3D model, accurately identifying all components in the model and obtaining dimensional parameters such as length, width, and height. Furthermore, by querying component attributes, it can obtain the component's material type and related parameters, such as the density and compressive strength of the wall material, providing detailed parameter guidance for subsequent construction. S4: Programming is performed based on the part drawing, imported into the CNC machine tool, and then the parts with specified size and shape are accurately cut and processed; S5: Assemble parts according to specific construction steps, then install, cast, and support the SPCS cavity wall. Construction equipment will determine the interface bonding relationship and mechanical action sequence between prefabricated components based on the coordinate positions and weights in the BIM model database. Combined with the load curve parameters of lifting equipment such as cranes, the equipment's load capacity range is determined. Construction equipment uses a topological sorting algorithm to sort the prefabricated components, calculating a feasible component assembly sequence and corresponding support system material and dimensional information that meets interface constraints and equipment capabilities. This creates an editable construction method and process. For example, the BIM model is modularized and split according to building blocks to determine component dimensions and cast-in-place section dimensions, and components are numbered and marked with installation directions, thereby increasing construction speed and significantly reducing installation errors. For example, the position and specifications of adjustable support rods are determined based on component type and force calculations, and the structure of the adjustable support rods is then used to improve installation convenience.

[0038] As a preferred embodiment, in step S5, if Figure 1As shown, during the construction of the SPCS cavity wall on the bottom floor, the composite plate 1 is first set, and then the ground anchor 2 is installed. Then the SPCS cavity wall 9 is hoisted and placed on the height-adjustable base 6. After the height is adjusted by the height-adjustable base 6, it is sealed by the sealing plate 7. Then the first adjustable support rod 3 is installed, and the support angle of the first adjustable support rod 3 is adjusted by the support angle adjustment member 5; then the second adjustable support rod 4 is installed, and the support angle of the second adjustable support rod 4 is fine-tuned by the support angle adjustment member 5. The support angle can be adjusted by the first threaded connecting rod 32, the length adjustment locking member 36 and the second threaded connecting rod 43 to ensure that the SPCS cavity wall 9 is in a vertical position; then the SPCS cavity wall 9 is poured. After the concrete in the SPCS cavity wall 9 reaches the specified strength, the sealing plate 7, the first adjustable support rod 3, the second adjustable support rod 4, the support angle adjustment member 5 and the ground anchor 2 are removed in sequence to complete the construction.

[0039] The present invention adopts BIM modeling and simulation to improve the rationality of design, and then extracts data, and uses intelligent CNC machine tools to cut and process an SPCS cavity wall assembly combination system with precise size and shape, forming a "cavity + overlap + cast-in-place" construction method. Through the lifting and installation of the SPCS cavity wall, the first adjustable support rod 3 and the second adjustable support rod 4 provide support for the casting of the SPCS cavity wall, ensuring the quality of casting, greatly saving the construction process, precise size control, reliable reinforcement method, and good molding effect; and the SPCS cavity wall has a light weight and can be produced in larger sizes, effectively reducing the number of joints between prefabricated components and cast-in-place structures, while facilitating transportation and construction, effectively reducing the cost of selecting lifting and hoisting equipment, and reducing material waste. At the same time, the SPCS cavity wall is connected in the form of an intermediate cavity, and the assembled ring reinforcement 8 is used as a skeleton, which is convenient for vertical centering and installation, and convenient construction. There is no reserved expenditure steel bar at the ends of the four sides of the SPCS cavity wall, which has a good construction fault tolerance rate and ensures the safety of construction workers, thereby improving the efficiency of building construction.

[0040] Although the above describes and illustrates the specific embodiments of the present invention in detail, it should be pointed out that: we can make various equivalent changes and modifications to the above embodiments based on the concept of the present invention, and the functional effects produced therefrom still do not exceed the spirit covered by the specification, and should all be within the scope of protection of the present invention.
