After 2020, prefabricated buildings will account for over 30% of domestic construction. However, traditional prefabricated components suffer from high transportation energy consumption and frequent wet work on-site. While lightweight steel keel systems enable dry construction, their sound insulation and fire resistance require infilling with materials like rock wool, increasing carbon emissions by approximately 15%.

[0024] Specifically, during assembly, the fixing part 2 is fixed to the outside of the vertical H-shaped steel column 1 by fixing bolt 1 3, and then the transverse C-shaped steel beam 5 is fixed to the outside of the vertical H-shaped steel column 1 and the fixing part 2 by fixing bolt 2 4, and then the connecting part 6 is installed, and then fixed to the connecting part 6 by fixing bolt 3 9 through the embedded part 7. The outer wall of the magnesium-based fireproof board 8 is fixed with the vacuum insulation board 10 and the straw fiber cement board 11 in turn to form a module with fire prevention, heat preservation and sound insulation functions. At the same time, the steel frame and the functional module are quickly assembled through bolt connection to meet the environmental protection and structural performance requirements of the prefabricated building.

[0025] The interior of the magnesium-based fireproof board 8 is fixedly connected to a T-shaped embedded part 14, the outer wall of the T-shaped embedded part 14 is fixedly connected to a hanging plate 15, the outer wall of the hanging plate 15 is provided with a side card groove 2 18, the outer wall of the hanging plate 15 is provided with a side card groove 17, and the lower surface of the hanging plate 15 is provided with a bottom end card groove 16. The thickness of the straw fiber cement board 11 is 30 mm and the density is 1.8 g / cm³. The thermal conductivity coefficient of the vacuum insulation panel 10 is ≤0.008 W / m·K. The thickness of the magnesium-based fireproof board 8 is 15 mm, and the outer wall of the vertical H-shaped steel column 1 is provided with a fixed component.

[0026] Specifically, the T-shaped embedded parts 14 need to be pre-embedded in the interior of the magnesium-based fireproof board 8 and fixedly connected to the hanging board 15. The bottom slot 16 opened on the lower surface of the hanging board 15, and the side slot 17 and side slot 2 18 opened on both sides are all used to provide locking space. The straw fiber cement board 11 adopts a lightweight and high-strength composite structure, which is durable and easy to construct. Straw fiber has environmental protection characteristics and can reduce carbon emissions in the production stage. The internal microporous structure forms a natural sound absorption layer that can effectively block external noise and improve the indoor sound environment quality. The vacuum insulation board 10 can effectively block the heat conduction path of the wall due to its low thermal conductivity, forming an efficient thermal insulation layer, which not only reduces building energy consumption but also reduces the deadweight of the wall, and expands more usable space indoors. The magnesium-based fireproof board 8 serves as the core fireproof structure of the wall. Its inorganic mineral matrix releases crystalline water to form an insulation layer when encountering fire, which can delay heat transfer and provide reliable fire protection for the building. The role of the fixing component is to provide pre-fixation for the installation process of the functional module.

[0027] The fixing assembly also includes a rack 25, the tooth end of the rack 25 is meshed with the tooth end of the gear 20, and the lower surface of the rack 25 is fixedly connected with a side L-shaped clip 26, the outer wall of the side L-shaped clip 26 is slidably connected to the inner wall of the rectangular box 13, and the outer wall of the side L-shaped clip 26 is provided with a limiting groove 29, and the outer wall of the rectangular box 13 is fixedly connected with a fixing strip 27, and the outer wall of the fixing strip 27 is fixedly connected to the limiting block 28, and the outer wall of the limiting block 28 is slidably connected to the inner wall of the limiting groove 29, and the outer wall of the side L-shaped clip 26 is slidably connected to the inner wall of the side slot 17; the fixing assembly also includes a rack 25, the tooth end of the rack 25 is meshed with the tooth end of the gear 20, and the lower surface of the rack 25 is fixedly connected with a side L-shaped clip 26, and the outer wall of the side L-shaped clip 26 is slidably connected to the inner wall of the rectangular box 13, and the outer wall of the side L-shaped clip 26 is provided with a limiting groove The outer wall of the rectangular box 13 is fixedly connected to a fixing strip 27, and the outer wall of the fixing strip 27 is fixedly connected to the side card slot 2 18. The outer wall of the side card slot 2 18 is slidably connected to the inner wall of the limiting groove 29, and the outer wall of the side L-shaped card strip 26 is slidably connected to the inner wall of the side card slot 17; the fixing assembly also includes a rack 30, the tooth end of the rack 30 is meshed with the tooth end of the gear 20, and the upper surface of the rack 30 is fixedly connected There is a side L-shaped clip 2 31, the outer wall of the side L-shaped clip 2 31 is slidably connected to the inner wall of the rectangular box 13, the outer wall of the side L-shaped clip 2 31 is provided with a limiting groove 2 34, the outer wall of the rectangular box 13 is fixedly connected to a fixing strip 2 33, the outer wall of the fixing strip 2 33 is fixedly connected to a round pin 2 32, the outer wall of the round pin 2 32 is slidably connected to the inner wall of the limiting groove 2 34, and the outer wall of the side L-shaped clip 2 31 is slidably connected to the inner wall of the side slot 1 17.

[0028] Specifically, the function of the fixing component is to firmly pre-fix the functional modules, namely the magnesium-based fireproof board 8, the vacuum insulation board 10, and the straw fiber cement board 11, during their installation, thereby optimizing the work process, improving the installation efficiency, releasing the lifting equipment, improving the turnover efficiency of large equipment, avoiding the waiting time of the equipment, and providing a safe platform for subsequent operations. Specifically, during installation, the functional module drives the hanging plate 15 to move and fit into the outer wall of the rectangular box 13, and causes the functional module to move downward as a whole, causing the lower L-shaped clip 22 to passively slide into the inner wall of the bottom slot 16. During this process, the lower L-shaped clip 22 will be forced to move downward and slide on the inner wall of the rectangular box 13, while driving the fixed block 23 to move downward, causing the spring 24 to be forced to contract. During the downward movement of the lower L-shaped clip 22, the lower L-shaped clip 22 will drive the rack 21 to move downward. During the downward movement of the rack 21, the gear 20 meshing with it will be caused to rotate and drive the rotating column 19 to rotate. During the rotation of the gear 20 In the process of rotating the gear 20, the gear 20 drives the rack 25 meshing with it to move inward, thereby driving the side L-shaped card strip 1 26 to move inward and slide on the inner wall of the rectangular box 13, thereby driving the side L-shaped card strip 1 26 to move inward and slide into the inner wall of the side card slot 1 17. At the same time, during the rotation of the gear 20, the gear 20 drives the rack 3 30 to move inward, thereby driving the rack 3 30 to drive the side L-shaped card strip 2 31 to move inward and slide on the inner wall of the rectangular box 13, thereby driving the side L-shaped card strip 2 31 to move inward and slide into the inner wall of the side card slot 2 18. The wall is fixed by sliding the lower L-shaped clip 22 into the inner wall of the bottom card slot 16, the side L-shaped clip 1 26 into the inner wall of the side card slot 1 17, and the side L-shaped clip 2 31 into the inner wall of the side card slot 2 18, thereby achieving pre-fixation before the functional module is installed. This can optimize the workflow, improve installation efficiency, free up lifting equipment, improve the turnover efficiency of large equipment, avoid equipment waiting time, and provide a safe platform for subsequent operations. It can also prevent tipping and slipping, and improve installation accuracy and quality. During the outward movement of the side L-shaped clip 1 26, the outer wall of the limit block 28 will passively slide into the inner wall of the limit slot 1 29. At the same time, during the movement of the side L-shaped clip 2 31, the round pin 2 32 will passively slide into the inner wall of the limit slot 2 34, thereby limiting the side L-shaped clip 2 31 and the side L-shaped clip 1 26.

[0029] This embodiment also provides an installation process for an environmentally friendly prefabricated wall structure system, comprising the following steps: S1. Position and fix the foundation embedded parts; S2. Assemble the steel frame and install functional modules to form the wall structure system; S3, fasten the embedded part 7 and the connecting part 6; S4. Hoist the wall structure system and calibrate the verticality; S5. Process and seal the seams.

[0030] In S1, a three-dimensional laser total station is used to locate the foundation embedded parts, with an allowable deviation of ≤3mm. The embedded parts are fixed by expansion bolts, and the plane position and verticality errors are ≤2mm.

[0031] Specifically, the wall side foundation embedded parts are located by a three-dimensional laser total station to provide a reliable reference point for the subsequent steel frame hoisting, ensuring that the overall verticality and plane position of the wall structure system meet the design requirements. The wall side foundation embedded parts are fixed to the foundation structure through expansion bolts to form a reliable anchor connection, and the plane position and verticality errors of the wall side foundation embedded parts are controlled within a small range to ensure that the axes of the vertical H-shaped steel column 1 and the horizontal C-shaped steel beam 5 are aligned during installation, avoiding additional stress on the steel frame due to foundation deviation.

[0032] In S2, assembling the steel frame and installing the functional modules specifically include: fixing the fixing part 2 to the outside of the vertical H-shaped steel column 1 by fixing bolts 1 3, and then fixing the horizontal C-shaped steel beam 5 to the outside of the vertical H-shaped steel column 1 and the fixing part 2 by fixing bolts 2 4, and then installing the fixing assembly, and then installing the connecting part 6. After the installation of the connecting part 6 is completed, the magnesium-based fireproof board 8, the vacuum insulation board 10 and the straw fiber cement board 11 together with the embedded part 7 are inserted into the outer wall of the connecting part 6, and by driving the hanging plate 15, the lower L-shaped card strip 22 is caused to slide into the inner wall of the bottom end slot 16, the side L-shaped card strip 1 26 slides into the inner wall of the side slot 2 18, and the side L-shaped card strip 2 31 slides into the inner wall of the side slot 1 17, and finally the embedded part 7 and the connecting part 6 are fixed by fixing bolts 3 9 to form a wall structure system.

[0033] Specifically, fixing bolt 1 3 fastens the fixing part 2 to the outside of the vertical H-shaped steel column 1 to form a basic connection node, and fixing bolt 2 4 fixes the transverse C-shaped steel beam 5 to the outside of the vertical H-shaped steel column 1 and the fixing part 2 to form a rigid steel skeleton grid frame. Connectors 6 are installed at the steel skeleton grid nodes to provide a guide and positioning interface for the functional module. As a key transition component between the steel skeleton and the functional module, the connector 6 efficiently transfers the weight of multi-layer panels such as magnesium-based fireproof panels 8 to the steel skeleton, effectively avoiding on-site welding or complex adjustments, and improving the efficiency of prefabricated construction.

[0034] In S3, when the embedded part 7 is fixed to the connecting part 6, a torque wrench is used to apply a tightening torque of 15 N·m, and the torque is confirmed to meet the standard by the mechanical dial.

[0035] Specifically, a torque wrench is used to accurately apply a tightening torque of 15 N·m to the fixing bolt 3 9 to ensure that the embedded part 7 and the connecting part 6 reach the designed preload force. This not only prevents the bolt from loosening due to insufficient tightening force, but also avoids thread stripping or component deformation caused by excessive torque. The operator can confirm in real time and intuitively that the torque meets the standard through the torque wrench dial, providing a visual basis for the tightening operation, effectively reducing the subjective error of manual tightening, and ensuring consistent torque at all connection nodes.

[0036] In S4, a robotic arm equipped with a gyroscope is used to hoist the wall structure system. The verticality deviation is controlled within H / 1500 through a hydraulic fine-tuning device. Pressure sensors are installed at the nodes of the steel skeleton to transmit the support force data wirelessly. In S5, silicone sealant is sprayed along the module joints, the seam width is controlled at 8 to 10 mm, and nano-silica sealing strips are embedded inside.

[0037] Specifically, an intelligent lifting system with a gyroscope robotic arm is used to monitor and dynamically calibrate the three-dimensional posture of the steel frame in real time. The hydraulic system automatically compensates for the lifting tilt to ensure that the frame is stable during lifting, translation, and positioning. The plunger pump drives the fine-tuning support to achieve fine leveling within the range of ±0.5mm / m, effectively overcoming errors such as uneven foundation and lifting inertia, and ensuring vertical connection with the main structure. Pressure sensors are installed at key nodes to wirelessly transmit force data to the terminal and dynamically monitor stress distribution. Once a local overload risk is detected, the lifting posture can be adjusted remotely to ensure that the wall system is balanced, safe, and reliable during installation.

[0038] Evenly spraying silicone sealant along the joints between the magnesium-based fireproof board 8, the straw fiber cement board 11, and the vacuum insulation board 10 can form a continuous sealing barrier between the boards, which can adapt to the slight deformation that may occur at the joints. During construction, the width of the glue seam is precisely controlled within the range of 8 to 10 mm. This not only provides the sealant with optimal expansion and contraction space, but also avoids material waste or reduced sealing effect, ensuring that the sealant maintains a good elastic state during long-term use. A nano-silica sealing strip is embedded on the inside of the silicone sealant. This material has a porous structure that can absorb water vapor and effectively inhibit the growth of mold.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
