Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a method for installing prefabricated walls in medical buildings. Background Technology

[0002] With the continuous development of the construction industry, prefabricated buildings are gradually gaining popularity due to their advantages such as high efficiency and environmental friendliness. However, in practical applications, the construction process of prefabricated walls suffers from unreasonable process arrangement, leading to low on-site installation efficiency and impacting construction progress. Furthermore, traditional construction methods do not meet the high accuracy requirements of environmental dimensions, necessitating frequent adjustments during on-site construction, increasing construction time and costs. Summary of the Invention

[0003] The main objective of this invention is to propose a method for installing prefabricated walls in medical buildings, aiming to solve the technical problem of long construction cycles for prefabricated walls in related technologies.

[0004] To achieve the above objectives, the present invention proposes a method for installing prefabricated walls in medical buildings, the method comprising the following steps:

[0005] Construct a frame structure, and obtain the hanger structure, wall panel structure, and bottom groove structure based on the dimensional data of the frame structure;

[0006] Install the hanger structure and fix the hanger structure to the floor slab;

[0007] The electromechanical equipment is threaded through the hanger structure and installed onto the floor slab;

[0008] The flatness of the ground of the frame structure is tested, and the judgment result is obtained;

[0009] When the judgment result is flat, the bottom groove structure is installed on the ground;

[0010] The wall panel structure, the hanger structure, and the bottom groove structure are assembled to obtain multiple prefabricated walls;

[0011] Joint treatment is performed between multiple prefabricated wall sections.

[0012] In one embodiment, the hanger structure includes a hanger, a first gypsum board, and an upper corner bracket; the step of installing the hanger structure and fixing it to the floor slab includes:

[0013] Holes are made in the hanger, and the hanger is fixed to a predetermined position on the floor slab;

[0014] Assemble the hanger with the first gypsum board, and install the first gypsum board on both sides of the hanger;

[0015] The upper corner piece is installed on the bottom side of the hanger.

[0016] In one embodiment, the bottom groove structure includes a bottom groove and a support member; the step of installing the bottom groove structure when the judgment result is flat includes:

[0017] When the judgment result is flat, an installation hole is opened in the middle of the bottom groove, and the bottom groove is installed on the ground;

[0018] The support member is adjusted, and the adjusted support member is assembled into the bottom groove.

[0019] In one embodiment, the step of assembling the wall panel structure, the hanger structure, and the bottom groove structure to obtain multiple prefabricated walls includes:

[0020] Connect the bottom of the wall panel structure to the bottom groove structure;

[0021] Connect the top of the wall panel structure to the hanger structure;

[0022] Return to the step of connecting the top of the wall panel structure to the hanger structure until multiple prefabricated walls are obtained.

[0023] In one embodiment, the bottom groove structure includes a fourth gypsum board, a bottom groove, and a supporting member; the wall panel structure includes a wall panel; the step of connecting the bottom of the wall panel structure to the bottom groove structure includes:

[0024] The fourth gypsum board is installed on both sides of the bottom groove, and the fourth gypsum board is assembled with the bottom groove using fasteners;

[0025] Assemble the fourth gypsum board, the support member, and the wall panel, so that the wall panel is fixed to the bottom groove.

[0026] In one embodiment, the hanger structure includes a lower corner piece, an upper corner piece, a heat insulation layer, a first gypsum board, and a second gypsum board; the wall panel structure includes a third gypsum board and a wall panel; the step of connecting the top of the wall panel structure to the hanger structure includes:

[0027] Assemble the lower corner piece to the upper part of the wall panel;

[0028] Assemble the lower corner piece with the upper corner piece;

[0029] The heat insulation layer is filled at the connection between the upper corner piece and the lower corner piece.

[0030] The second gypsum board is installed on both sides of the upper corner piece and the lower corner piece. The upper part of the second gypsum board abuts against the first gypsum board in the hanging structure, and the lower part of the second gypsum board abuts against the third gypsum board in the wall structure.

[0031] In one embodiment, the hanger structure includes a plurality of vertical hangers, and the step of passing the electromechanical equipment through the hanger structure and installing it to the floor slab includes passing the electromechanical pipes of the electromechanical equipment between adjacent vertical hangers of the hanger structure and installing the electromechanical pipes to the floor slab through connectors.

[0032] In one embodiment, the step of splicing the prefabricated walls together includes:

[0033] When there is a gap between the insulation panels of adjacent prefabricated walls, fireproof adhesive is used to fill the gap to complete the joint treatment.

[0034] In one embodiment, the wall panel structure includes multiple prefabricated wall panels and a fifth gypsum board; the step of splicing the multiple prefabricated wall panels further includes:

[0035] When manufacturing a single prefabricated wall panel in the factory, the left and right sides of the fifth gypsum board are each cut to a predetermined length so that the actual length of a single fifth gypsum board is less than the standard size, so as to reserve a joint position after the installation of two adjacent prefabricated wall panels.

[0036] After the prefabricated wall is installed on site, insulation boards that match the reserved joint size are filled at the joint positions.

[0037] The filled seams are then painted.

[0038] In one embodiment, the preset length is 150mm, the standard size of a single fifth gypsum board is 1200mm, the actual length after cutting is 900mm, the width of the joint reserved after the installation of adjacent prefabricated walls is 300mm, and the size of the filling insulation board is 300mm.

[0039] The technical solution of this invention involves installing a hanger structure on the floor slab before installing the base trench structure. This creates an internal transport space between the hanger structure and the floor within the frame structure before the base trench structure is installed. This internal transport space can be used to transport construction materials during the construction process, greatly facilitating construction work, significantly improving construction efficiency, and substantially increasing overall construction efficiency. Furthermore, because the hanger structure is installed on the floor slab of the frame structure, the movement of construction equipment is not restricted during the subsequent installation of the base trench structure, further ensuring high construction efficiency.

[0040] The technical solution of this invention involves conducting a flatness test on the ground of the frame structure to ensure that the ground is flat before installing the bottom channel structure. This not only guarantees the stability and flatness of the precast wall panel installation but also reduces rework and adjustment time caused by uneven ground, further shortening the construction cycle. When assembling the wall panel structure, hanger structure, and bottom channel structure, since each component is prefabricated based on precise frame structure dimensions, on-site assembly is quick and accurate, reducing on-site construction time and labor intensity. Standardized joint treatment also ensures the integrity and aesthetics of the wall, reducing subsequent repair and maintenance workload. Final as-built verification ensures that the construction quality meets design requirements, avoiding delays and additional costs caused by construction quality issues.

[0041] The technical solution of this invention effectively solves the problem of long construction cycles in traditional construction by optimizing the construction process and the precise matching of prefabricated components, thereby significantly improving construction efficiency and bringing remarkable technical benefits to building construction.

[0048] This invention proposes a method for installing prefabricated walls in medical buildings.

[0049] Please see Figure 1 In one embodiment of the present invention, the method for installing prefabricated walls in medical buildings includes the following steps:

[0050] Construct a frame structure, and obtain the hanger structure, wall panel structure, and bottom groove structure based on the dimensional data of the frame structure;

[0051] Install the hanger structure and fix the hanger structure to the floor slab;

[0052] The electromechanical equipment is threaded through the hanger structure and installed onto the floor slab;

[0053] The flatness of the ground of the frame structure is tested, and the judgment result is obtained;

[0054] When the judgment result is flat, the bottom groove structure is installed on the ground;

[0055] The wall panel structure, the hanger structure, and the bottom groove structure are assembled to obtain multiple prefabricated walls;

[0056] Joint treatment is performed between multiple prefabricated wall sections.

[0057] In this embodiment, it can be understood that the method is applied in the field of medical buildings, and the method includes steps S10-S70:

[0058] Step S10: Construct the frame structure and obtain the hanger structure, wall panel structure, and base trench structure based on the dimensional data of the frame structure. It should be noted that first, a concrete frame structure, including the ground, floor slabs, beams, and columns, is constructed on the construction site; this forms the foundation for the entire precast partition wall installation. Then, high-precision measuring tools such as laser levels are used to perform detailed measurements of the frame structure, obtaining precise position and dimension data of the ground, floor slabs, beams, and columns. This data will be input into the BIM (Building Information Modeling) system for designing hangers, wall panels, and base trench structures that precisely match the frame structure. Through the BIM model, the routing of mechanical and electrical equipment and the location of pre-drilled holes for hangers can be precisely planned, while optimizing the spacing of wall panel compartments to ensure efficient material utilization and ease of construction. This not only improves construction accuracy and reduces on-site errors and rework but also reduces material waste and construction costs through advance planning and optimized design, improving the efficiency and quality of the entire construction process. The frame structure is constructed based on initial pre-built model drawings, which may include, but are not limited to, BIM model drawings or CAD model drawings. It is understandable that the construction of the medical building's frame structure involves completing the concrete frame structure construction on-site, including the ground, ceiling, beams, and columns. The assembled frame structure is then measured on-site using equipment such as laser levels and total stations to determine the position and dimensions of the ground, floor slabs, beams, and columns. This precise data is compared with pre-built model drawings. If the on-site correction error is too large, the pre-built model drawings are adjusted promptly to obtain an adjusted 3D BIM model of the prefabricated building. This ensures that subsequent prefabricated wall panels and other components can accurately adapt to the adjusted frame structure, avoiding installation problems caused by dimensional deviations and improving construction accuracy and efficiency. The wall materials are processed to obtain the hanging structure, wall panel structure, and base channel structure. Wall materials include, but are not limited to, steel, framing, and aluminum. This embodiment utilizes modern production technologies (such as CNC (Computer Numerical Control), robotic arms, or laser cutting) to process the wall materials. Understandably, these hanger structures, wall panel structures, and base channel structures are manufactured in the factory according to design requirements and pre-assigned a unique set of codes to facilitate direct positioning and assembly on-site. At the construction site, workers transport the prefabricated wall panels to designated floors and rooms according to the codes and connect and fix them to the hanger structures and base channel structures one by one in numerical order. The wall panel structure includes components such as a standard wall frame, junction boxes, rock wool layers, and gypsum board, and has undergone assembly and preliminary acceptance in the factory to ensure correct internal installation and meet basic on-site installation requirements. Its dimensions, shape, and internal structure are precisely designed according to the adjusted prefabricated building 3D BIM model. The hanger structures and base channel structures are obtained by performing a roll-processing procedure on the wall materials based on the dimensional data of the adjusted prefabricated building 3D BIM model.Understandably, the hanger structure refers to the hanger structure designed and manufactured according to the BIM model. The hanger structure includes hangers, corner brackets, and the first gypsum board, etc. The hanger includes multiple vertical hangers and multiple horizontal hangers, with a horizontal hanger connecting two adjacent vertical hangers. A certain gap is reserved between adjacent vertical hangers when installed to the floor slab to allow space for mechanical and electrical equipment. The base channel structure refers to the base channel used for installation on the ground, with supporting components for positioning and supporting the bottom of the precast wall panels. The wall panel structure includes the outermost decorative panel, the inner insulation board (gypsum board or cement board), the rock wool layer, mechanical and electrical equipment, the standard wall frame, the fifth gypsum board, and another outermost decorative panel. First, the standard wall frame is fabricated and installed, ensuring its stability and verticality. The mechanical and electrical components in the wall panel structure are then hooked into the frame using horizontal light steel keels and secured. Next, a fifth gypsum board is fixed to one side of the frame with screws. Next, fill the wall with a layer of rock wool, ensuring a tight seal between the rock wool and the plasterboard and framework. Then, use screws to secure the fifth plasterboard on the other side of the framework.

[0059] Step S20: Install the hanger structure and fix it to the floor slab. It should be noted that, firstly, based on the hanger installation positions and hole locations reserved in the BIM model, expansion bolts are used to firmly install the hanger structure onto the floor slab. This installation method ensures a tight connection between the hanger and the floor slab, providing stable top support for the subsequent installation of precast wall panels, effectively avoiding potential shaking or displacement of the wall panels during use, and improving the stability of the entire partition wall system. Secondly, since the hanger has pre-reserved pipeline channels according to the design of the electromechanical equipment during the production stage, after the hanger installation is completed, the electromechanical equipment can be directly installed according to the pre-reserved channels. This approach not only improves construction efficiency and reduces the time and workload of on-site pipeline layout, but also avoids errors and safety hazards that may be caused by on-site drilling or cutting operations, ensuring the accuracy and reliability of electromechanical equipment installation. Finally, this installation method allows for the smooth installation of gypsum board or cement board on both sides above the hanger to meet fireproofing and sound insulation requirements, further enhancing the fireproofing and sound insulation performance of the partition wall and improving the building's usability.

[0060] Step S30: The electromechanical equipment is threaded through the hanger structure and installed onto the floor slab. It should be noted that the electromechanical equipment here includes pipes and pipelines, such as HVAC, electrical, water supply and drainage, fire protection, and medical gas systems. First, after the hanger is installed, the electromechanical equipment pipelines are threaded through the pre-designed channels in the hanger, ensuring smooth pipeline routing that meets design requirements. This is to rationally arrange the pipelines and avoid intersections or confusion during subsequent installation, improving the neatness and standardization of the construction. Second, the main body of the electromechanical equipment is threaded through the hanger, with the spacing between the multiple vertical hangers allowing the equipment to pass through. The equipment is then fixed to the floor slab using connectors (hangers, brackets, etc.). This ensures the stability of the equipment during use, preventing swaying or displacement from affecting its normal operation, and also facilitates later maintenance and repair. Finally, the electromechanical equipment is debugged and inspected to ensure it functions properly and connects seamlessly with the building's overall electromechanical system. This step verifies that the installation of the equipment meets requirements and ensures its proper functioning, thereby improving the reliability and safety of the entire building system. This installation method effectively improves construction efficiency, reduces on-site construction time and labor costs, and ensures the installation quality of the electromechanical equipment, providing a reliable guarantee for the normal use of the building.

[0061] Step S40: Perform a flatness test on the ground of the frame structure to obtain a judgment result. It should be noted that, firstly, a laser level is used to comprehensively inspect the completed frame structure ground, obtaining flatness data and comparing it with a preset standard to determine if the ground is flat. This is to ensure that the flatness of the ground meets the requirements for installing precast wall panels, as ground flatness directly affects the installation quality and stability of the wall panels. A flat ground ensures vertical installation of the wall panels, avoiding tilting or deformation caused by uneven ground, thereby improving the quality and service life of the entire partition wall system. Secondly, if the test results show that the ground is flat, a bottom groove structure is installed on the ground. During installation, bolts are used to fix the bottom groove to the ground, and the support members inside the bottom groove are adjusted to a suitable height so that the bottom of the precast wall panel can be subsequently snapped onto the support members. Installing the bottom groove structure provides stable bottom support for the precast wall panel and allows for fine-tuning of the wall panel height through the support members, ensuring the flatness of the wall panel in the horizontal direction. Simultaneously, the bottom groove structure can also form a good seal with the ground, improving the fire resistance and sound insulation performance of the wall panel. Finally, the prefabricated wall panels are installed one by one onto the supports in the bottom groove, and the lower corner pieces are connected to the upper corner pieces and the standard framework of the wall with screws, thus fixing the upper part of the wall to the hanger. Rock wool layers are filled into the gaps between the corner piece connections, and two layers of gypsum board are installed on both sides from the lower-middle part of the hanger to the top of the gypsum board on the wall to seal for fireproofing and sound insulation. This assembly method enables rapid installation of prefabricated wall panels, reducing on-site construction time and labor costs. At the same time, standardized connectors and filling materials ensure the structural stability, fireproofing, and sound insulation performance of the wall panels, improving construction quality.

[0062] Step S50: When the judgment result is flat, install the bottom groove structure on the ground. It should be noted that when the judgment result is flat, firstly, bolts are used to fix the bottom groove structure to the ground. The bolts pass through the mounting holes in the middle of the bottom groove to ensure a firm connection between the bottom groove and the ground. This is to provide a stable support foundation for subsequent wall installation, preventing the wall from tilting or becoming unstable due to uneven ground, thereby ensuring the verticality and stability of the entire wall system. Secondly, the support component is adjusted to a suitable height and placed in the bottom groove. The groove of the support component has through holes for inserting adjusting bolts. By adjusting the nuts below, the vertical height of the protrusion can be finely adjusted. This allows for precise control of the wall's installation height, ensuring a tight fit between the wall and the ground, further improving the stability and integrity of the wall. Finally, the bottom of the precast wall is snapped onto the support, and the lower corner piece is connected to the upper corner piece and the standard frame of the wall using screws, so that the upper part of the wall is connected and fixed to the hanger. This connection method not only ensures the vertical stability of the wall, but also facilitates subsequent disassembly and reassembly, improving the flexibility and efficiency of construction. At the same time, the connection strength between the wall and the bottom groove is enhanced by the screw connection, ensuring the firmness and reliability of the entire wall system.

[0063] Step S60: Assemble the wall panel structure, the hanger structure, and the bottom groove structure to obtain multiple prefabricated walls. It should be noted that, firstly, the prefabricated wall panels are installed one by one onto the supports in the bottom groove according to their numbered sequence, ensuring a tight fit between the bottom of the wall panel and the support. By adjusting the height of the support, the wall panel achieves the designed verticality and flatness requirements. This is done to ensure the accuracy and stability of the wall panel installation, providing a good foundation for subsequent connection work and effectively avoiding installation problems caused by wall panel tilting or unevenness, thus improving construction quality. Secondly, screws are used to connect the lower corner pieces to the upper corner pieces and the standard frame of the wall, firmly connecting and fixing the top of the wall to the hanger. This connection method ensures the vertical stability of the wall panel. Simultaneously, the corner piece connection evenly distributes the weight of the wall panel to the hanger and bottom groove, enhancing the load-bearing capacity of the entire wall system and reducing the risk of deformation or damage caused by uneven local stress. Finally, rock wool layers are filled into the gaps at the corner joints to provide fireproofing, sound insulation, and heat insulation. Then, two layers of gypsum board are installed on both sides from the lower-middle part of the hanger to the top of the wall gypsum board, covering the corner joints to further seal for fireproofing and sound insulation, while also improving the overall aesthetics of the wall. This treatment not only enhances the functionality of the wall but also makes the wall surface smoother and cleaner, meeting the aesthetic requirements of interior decoration and improving the user experience.

[0064] Step S70 involves joint treatment between the prefabricated wall panels. It should be noted that, firstly, joint treatment is an operation to fill and seal the gaps formed during the installation of the prefabricated wall panels. Specifically, fire-retardant adhesive is used to fill the gaps between adjacent prefabricated wall panels, ensuring the gaps are tightly filled and preventing air and sound penetration. Secondly, if the gaps are large, pre-cut gypsum board or cement board can be used for filling. The dimensions of these boards are customized according to the actual size of the gap to ensure a smooth surface after filling. Finally, after the filling material is installed, plastering and painting are performed to make the entire wall surface look aesthetically pleasing and uniform. This joint treatment method not only effectively solves the problem of gaps between prefabricated wall panels, improving the integrity and aesthetics of the wall, but also enhances the fire resistance and sound insulation performance of the wall, further improving its functionality.

[0065] Understandably, after completing the installation and joint treatment of all wall panels, Z-shaped fasteners are installed on adjacent decorative panels (plasterboard or veneer) within the wall structure. Then, the outermost veneer is installed on the outside of each individual wall panel, completing the installation of the precast wall. It should be noted that, firstly, after completing the installation of all precast wall panels and the joint treatment between adjacent panels, the construction workers will install Z-shaped fasteners on the decorative panels (plasterboard or veneer) of each wall panel. The Z-shaped fasteners are installed to provide a stable connection point for securing the outermost veneer. This fastener design allows the veneer to be quickly and securely attached to the inner plasterboard, greatly improving installation efficiency. Furthermore, due to the special structure of the fasteners, a tight connection between the veneer and the inner plasterboard is ensured, enhancing the overall stability of the wall. Secondly, the construction workers will install the outermost veneer on the outside of each individual wall panel. By attaching the veneer to the previously installed Z-shaped fasteners, rapid installation of the veneer is achieved, while ensuring the flatness and aesthetics of the veneer. This installation method not only improves construction speed but also facilitates independent disassembly and maintenance of the decorative panels in the future without affecting other parts, reducing the impact on users in other rooms and improving the maintainability of the building. Finally, after completing these steps, the installation of the precast wall is finished. The entire wall system is not only structurally stable and has excellent thermal insulation performance, but also has a neat and beautiful appearance, meeting the high-efficiency, environmentally friendly, and high-quality requirements of modern building wall construction. Simultaneously, the connection of electromechanical equipment will be carried out, and the gaps at the connection points will be filled. After completion, the ceiling will be installed, and adhesive mats will be installed on the underside of the wall panels to cover the screw holes on both sides of the bottom groove structure.

[0066] The technical solution of this invention involves installing a hanger structure on the floor slab before installing the base trench structure. This creates an internal transport space between the hanger structure and the floor within the frame structure before the base trench structure is installed. This internal transport space can be used to transport construction materials during the construction process, greatly facilitating construction work, significantly improving construction efficiency, and substantially increasing overall construction efficiency. Furthermore, because the hanger structure is installed on the floor slab of the frame structure, the movement of construction equipment is not restricted during the subsequent installation of the base trench structure, further ensuring high construction efficiency.

[0067] The technical solution of this invention involves conducting a flatness test on the ground of the frame structure to ensure that the ground is flat before installing the bottom channel structure. This not only guarantees the stability and flatness of the precast wall panel installation but also reduces rework and adjustment time caused by uneven ground, further shortening the construction cycle. When assembling the wall panel structure, hanger structure, and bottom channel structure, since each component is prefabricated based on precise frame structure dimensions, on-site assembly is quick and accurate, reducing on-site construction time and labor intensity. Standardized joint treatment also ensures the integrity and aesthetics of the wall, reducing subsequent repair and maintenance workload. Final as-built verification ensures that the construction quality meets design requirements, avoiding delays and additional costs caused by construction quality issues.

[0068] The technical solution of this invention effectively solves the problem of long construction cycles in traditional construction by optimizing the construction process and the precise matching of prefabricated components, thereby significantly improving construction efficiency and bringing remarkable technical benefits to building construction.

[0069] In one embodiment of the present invention, the hanger structure includes a hanger, a first gypsum board, and an upper corner piece; the step of installing the hanger structure and fixing the hanger structure to the floor slab includes:

[0070] Holes are made in the hanger, and the hanger is fixed to a predetermined position on the floor slab;

[0071] Assemble the hanger with the first gypsum board, and install the first gypsum board on both sides of the hanger;

[0072] The upper corner piece is installed on the bottom side of the hanger.

[0073] In this embodiment, it can be understood that the method is applied in the field of medical buildings, and the method includes steps S21-S23:

[0074] Step S21: Holes are drilled in the hanger, and the hanger is fixed to a predetermined position on the floor slab. It should be noted that the predetermined position refers to the hanger installation location pre-planned according to the building's design requirements and the BIM model to meet the layout requirements of the electromechanical equipment. First, holes are pre-drilled in the hanger for subsequent connection to the floor slab, ensuring the hanger can be accurately installed on the floor slab and providing basic support for the stability of the entire wall. Second, expansion bolts are used to firmly fix the upper holes of the hanger to the concrete structure of the floor slab. This ensures that the hanger can bear the weight of the subsequent precast wall panels, providing stable top support for the wall panels. The beneficial effect is to ensure the vertical stability of the entire wall system, avoiding wall tilting or deformation due to insufficient top support, thereby improving the structural safety of the wall.

[0075] Step S22: Assemble the hanger with the first gypsum board, and install the first gypsum board on both sides of the hanger. It should be noted that the first gypsum board here is used to protect the wall panel structure and provide fire resistance and sound insulation; its material is gypsum board. For the fire resistance and sound insulation requirements of the building partition, the first gypsum board is connected to the upper sides of the hanger using screws. It is understood that the number of first gypsum boards is not limited and can be set according to specific needs; when higher fire resistance requirements are needed, two layers of first gypsum board can be installed above the hanger; when the fire resistance requirements are lower, one layer of first gypsum board is sufficient. Taking the installation of two layers of first gypsum board on both sides of the hanger as an example, specifically, firstly, the first layer of first gypsum board is fixed to the upper sides of the hanger with screws, ensuring a tight fit without gaps. Next, a second layer of first gypsum board is installed on the outside of the first layer, similarly fixed to the first layer and the hanger with screws. This double-layer gypsum board installation method not only enhances the seal between the hanger and the floor slab, effectively preventing dust and debris from entering, but also significantly improves the fire resistance and sound insulation performance of the entire wall system by utilizing the fire-resistant and sound-insulating properties of gypsum board. In terms of fire resistance, the double-layer gypsum board provides a longer fire resistance time, slowing the spread of fire; in terms of sound insulation, the double-layer structure can better absorb and block sound transmission, providing a quieter environment for the building space.

[0076] Step S23: Install the upper corner bracket on the bottom side of the hanger. It should be noted that this step is a preliminary preparation for assembling the hanger structure and the wall panel structure. The upper corner bracket is a metal component used to connect the hanger and the precast wall frame; it is L-shaped. The upper corner bracket is usually installed on the bottom side of the hanger, and its length is the same as the length of the hanger. It is fixed to the hanger with screws. The main function of the upper corner bracket is to firmly fix the precast wall to the hanger, ensuring the vertical stability of the wall and the overall structural strength. The number of upper corner brackets is not limited; multiple brackets can be installed. It is understood that after the hanger is installed, the upper corner bracket needs to be installed on its bottom side to prepare for the subsequent assembly of the hanger structure and the wall panel structure. The upper corner bracket has the same length as the hanger and is firmly connected to the bottom of the hanger with screws or other fasteners. This is to provide a stable support point for the subsequent connection of the precast wall, ensuring a stable connection between the wall and the hanger, thereby enhancing the stability of the entire wall structure.

[0077] In one embodiment of the present invention, the bottom groove structure includes a bottom groove and a support member; the step of installing the bottom groove structure when the determination result is flat includes:

[0078] When the judgment result is flat, the bottom groove is installed on the ground;

[0079] The support member is adjusted, and the adjusted support member is assembled into the bottom groove.

[0080] In this embodiment, it should be noted that the method includes steps S51-S52:

[0081] Step S51: When the judgment result is flat, the bottom groove is installed on the ground. It should be noted that the bottom groove is a U-shaped component installed on the building floor to support and fix the bottom of the prefabricated partition wall panel. Here, the bottom groove can be installed on the ground by means of, but not limited to, bolt connection, snap-fit, etc. In this invention, the bottom groove has equally spaced mounting holes in the middle, and the bottom groove is fixed to the ground by fasteners such as bolts and rivets. It is understood that when the ground flatness meets the requirements, firstly, the bottom groove is placed in the predetermined installation position, ensuring it is tightly fitted to the ground. The purpose of this is to ensure the accurate installation position of the bottom groove, providing a stable foundation for the subsequent wall installation. Its beneficial effect is to improve the accuracy and stability of the wall installation and reduce wall tilting or shaking caused by uneven ground. Secondly, the bottom groove is fixed to the ground using bolts. The tightening action of the bolts ensures a firm connection between the bottom groove and the ground. The reason for this is that the bolt connection provides sufficient strength to prevent displacement of the bottom groove during use. Its beneficial effect is that it enhances the fixing effect of the bottom groove and improves the stability of the entire wall system.

[0082] Step S52: Adjust the support component and assemble the adjusted support component into the bottom groove. It should be noted that a support component is also provided above the bottom groove to adjust the installation height of the wall panel, ensuring the vertical stability and horizontal flatness of the wall panel. The support component refers to the part used to adjust the height and stability of the wall during the installation of the precast wall, including structures such as W-shaped positioning protrusions and their adjusting bolts. Specifically, the W-shaped positioning protrusion is installed into the bottom groove. The two sides of the W-shaped positioning protrusion have extended edges that abut against the periphery of the bottom groove's opening direction. The adjusting bolt is located in the recess within the W-shaped positioning protrusion. By adjusting the adjusting bolt, the height of the support component within the bottom groove can be adjusted. The recess of the positioning protrusion has screw holes. The adjusting bolt passes through the screw holes and abuts against the bottom groove. By adjusting the nut of the adjusting bolt, the height of the positioning protrusion in the vertical direction can be adjusted. After the bottom groove structure and the wall panel structure are assembled subsequently, the height of the wall panel can be adjusted. The methods of assembling the support component into the bottom groove include, but are not limited to, bolt connections, snap-fit ​​connections, etc. Understandably, the height of the W-shaped positioning protrusions within the groove is adjusted based on actual ground conditions and wall height requirements. Fine-tuning of the height is achieved by inserting adjusting bolts into the recesses of the positioning protrusions and adjusting the nuts beneath them. This is done because uneven ground at the construction site may exist; adjusting the height of the positioning protrusions ensures the verticality and flatness of the wall after installation. The beneficial effect is enhanced wall installation accuracy, improving the overall quality and aesthetics of the building.

[0083] In one embodiment of the present invention, the wall panel structure includes multiple prefabricated wall panels, and the step of assembling the wall panel structure, the hanger structure, and the bottom groove structure to obtain multiple prefabricated walls includes:

[0084] Connect the top of the wall panel structure to the hanger structure;

[0085] Connect the bottom of the wall panel structure to the bottom groove structure;

[0086] Return to the step of connecting the top of the wall panel structure to the hanger structure until multiple prefabricated walls are obtained.

[0087] In this embodiment, it should be noted that this step includes steps S61-S63:

[0088] Step S61 involves connecting the bottom of the wall panel structure to the bottom groove structure. It should be noted that this step refers to connecting the bottom of the wall panel structure to the bottom groove structure. During the installation of the prefabricated partition wall panel, this involves fixing the bottom of the prefabricated wall panel to the pre-installed bottom groove structure to ensure the vertical stability and horizontal flatness of the wall panel. This connection process is one of the key steps in the installation of the prefabricated partition wall panel, ensuring that the entire wall system is firm, stable, and able to withstand various external forces during daily use. Essentially, the bottom of the prefabricated wall panel is aligned with the support member in the bottom groove, and the bottom of the wall panel is snapped onto the support member. The purpose of this is to use the support member to initially position the wall panel, ensuring its verticality and horizontality. Its beneficial effect is to improve the accuracy of the wall panel installation and ensure the overall aesthetics and stability of the installed wall panel.

[0089] Step S62 involves connecting the top of the wall panel structure to the hanger structure. It should be noted that this step refers to fixing the top of the prefabricated wall panel to the hanger using specific connectors, ensuring the wall panel's vertical stability and firmness. This process is one of the key steps in prefabricated wall installation, ensuring the wall can be stably supported on the main structure of the building. Understandably, firstly, the prefabricated wall panels are transported to the construction site and positioned according to pre-numbered labels. This ensures that each wall panel is accurately installed in its designated position, improving installation efficiency and avoiding rework due to incorrect positioning. Secondly, the top of the wall panel is connected to the bottom of the hanger using corner brackets. In one embodiment, the lower corner bracket is fixed to the standard frame of the wall panel with screws, then the upper corner bracket is connected to the bottom of the hanger with screws, and finally, the lower and upper corner brackets are fixed together with screws. This is done because the corner brackets provide a stable connection, ensuring the firmness between the wall panel and the hanger. Its beneficial effect is enhanced vertical stability of the wall, preventing swaying or displacement during use. In another embodiment, the wall can be assembled directly using an I-shaped corner bracket. The two ends of the I-shaped bracket are fixed to the bottom of the hanger and the top of the wall panel using bolts or screws. Finally, rock wool is filled into the gaps between the corner bracket connections to meet fireproofing and sound insulation requirements. Then, two layers of gypsum board or cement board are screwed to both sides of the corner bracket connection, respectively, to abut against the gypsum board above the hanger and the wall panel, further enhancing fireproofing and sound insulation. This is done to improve the overall performance of the wall and ensure it meets building codes and safety standards. It not only improves the fireproofing and sound insulation performance of the wall but also enhances its overall aesthetics.

[0090] Step S63: Return to the step of connecting the top of the wall panel structure to the hanger structure, until multiple prefabricated walls are obtained. It should be noted that the prefabricated wall refers to the wall after multiple wall panels, hanger structures, and bottom groove structures are installed. It can be understood that steps S61 and S62 are repeated to continue installing the second wall panel and the remaining walls, ensuring that each prefabricated wall is connected to both the hanger structure and the bottom groove structure.

[0091] In one embodiment of the present invention, the bottom groove structure includes a fourth gypsum board, a bottom groove, and a supporting member; the wall panel structure includes a wall panel; the step of connecting the bottom of the wall panel structure to the bottom groove structure includes:

[0092] The fourth gypsum board is installed on both sides of the bottom groove, and the fourth gypsum board is assembled with the bottom groove using fasteners;

[0093] Assemble the fourth gypsum board, the support member, and the wall panel, so that the wall panel is fixed to the bottom groove.

[0094] In this embodiment, step S61 includes steps S611-S612:

[0095] Step S611: Install the fourth gypsum board on both sides of the bottom groove, and assemble the fourth gypsum board to the bottom groove using fasteners. It should be noted that fasteners here include, but are not limited to, bolts and pins. The fourth gypsum board refers to the gypsum board located outside the bottom groove in a precast wall panel structure, used to cover and protect the bottom groove, and connected to the wall panel structure to enhance overall stability and fire resistance. It is usually connected to the bottom groove using fasteners such as screws, serving a sealing and reinforcing function, while also contributing to improving the overall aesthetics of the wall. Understandably, firstly, placing the fourth gypsum board on both sides of the bottom groove ensures a tight fit between the gypsum board and the outside of the bottom groove. This is to form a sealed structure, preventing dust and debris from entering the bottom groove, while also enhancing the structural stability of the bottom groove. Secondly, using fasteners such as screws to fix the fourth gypsum board to the bottom groove, through evenly distributed screw holes, ensures a firm connection between the gypsum board and the bottom groove, preventing loosening or detachment due to external forces. This installation method not only enhances the overall aesthetics of the wall but also improves its fire resistance and sound insulation performance. Since gypsum board itself has certain fire resistance and sound insulation properties, this method allows it to better fulfill its functions and provides a good foundation for subsequent decoration work.

[0096] Step S612: Assemble the fourth gypsum board, the support member, and the wall panel, fixing the wall panel to the bottom groove. It should be noted that the fourth gypsum board is explained above. The support member includes a W-shaped positioning protrusion and an adjusting bolt. The W-shaped positioning protrusion is installed inside the bottom groove at the top. By adjusting the adjusting bolt in the recess of the positioning protrusion, the installation height of the wall is adjusted. Furthermore, the adjusting bolt abuts against the bottom groove, ensuring the vertical stability and horizontal flatness of the wall. The wall panel refers to a prefabricated single wall panel, composed of a frame, electromechanical equipment, a rock wool layer, and an inner fifth gypsum board. It is the smallest unit of the factory-standard components used to form the entire partition wall panel. The connection methods between the support member and the wall panel include, but are not limited to, bolt connections, snap-fit ​​connections, and plug-in connections. It can be understood that, firstly, the fourth gypsum board is placed on the outside of the bottom groove, abutting against it to ensure accurate positioning for effective connection with the wall panel and the bottom groove. The purpose of this is to tightly connect the wall panel to the base groove using the fourth gypsum board, while also providing sealing and fireproofing, enhancing the stability and safety of the entire wall panel system. Its beneficial effects include increased connection strength between the wall panel and the base groove, reduced air infiltration, and improved sound insulation and fire resistance. Secondly, the support (W-shaped positioning protrusion) is installed inside the base groove, and its height is adjusted using adjusting bolts to ensure a tight fit with the base groove. This ensures the wall panel achieves the precise height requirements during installation, while the support (W-shaped positioning protrusion) provides stable support, preventing tilting or displacement during installation. Its beneficial effects include ensuring the vertical stability and horizontal flatness of the wall panel, improving installation accuracy and quality. Finally, the bottom of the prefabricated individual wall panel is snapped onto the support (W-shaped positioning protrusion), and screws are used to securely connect the fourth gypsum board, support, and wall panel. This is to firmly fix the wall panel to the base groove, ensuring its stability. The above setup achieves a stable connection between the wall panel and the bottom groove, enhancing the integrity and stability of the entire wall panel system, while also facilitating subsequent disassembly and maintenance.

[0097] In one embodiment of the present invention, the hanger structure includes a lower corner piece, an upper corner piece, a heat insulation layer, a first gypsum board, and a second gypsum board; the wall panel structure includes a third gypsum board and a wall panel; the step of connecting the top of the wall panel structure to the hanger structure includes:

[0098] Assemble the lower corner piece to the upper part of the wall panel;

[0099] Assemble the lower corner piece with the upper corner piece;

[0100] The heat insulation layer is filled at the connection between the upper corner piece and the lower corner piece.

[0101] The second gypsum board is installed on both sides of the upper corner piece and the lower corner piece. The upper part of the second gypsum board abuts against the first gypsum board in the hanging structure, and the lower part of the second gypsum board abuts against the third gypsum board in the wall structure.

[0102] In this embodiment, it should be noted that step S62 includes S621-S624:

[0103] Step S621: Assemble the lower corner piece to the upper part of the wall panel. It should be noted that the explanation of the lower corner piece is as described above, and will not be repeated here. After completing the step of installing the hanger structure to the floor slab, fix the lower corner piece to the top of the wall frame. It is understood that the lower corner piece can be connected and fixed to the upper part of the wall panel using bolts, screws, and nuts. By firmly fixing the wall panel to the hanger, the vertical stability of the wall and the overall structural integrity are ensured. Its beneficial effect is that it enhances the connection strength between the wall and the hanger, enabling the wall to withstand greater external forces, and improving the service life and reliability of the wall.

[0104] Step S622: Assemble the lower corner piece and the upper corner piece. It should be noted that the lower corner piece is a metal component used to connect the hanger to the precast wall frame, and it is L-shaped. The lower corner piece is installed below the upper corner piece, i.e., on the side facing away from the hanger, and is connected to the upper corner piece by screws. The lower corner piece is also fixed to the top of the precast wall frame by screws. The main function of the lower corner piece is to firmly fix the precast wall to the hanger, ensuring the vertical stability of the wall and the overall structural integrity. The number of lower corner pieces is not limited; multiple pieces can be used. It is understood that, firstly, after the hanger structure is installed onto the floor slab in the previous steps, an upper corner piece is installed below the hanger structure; placing the lower corner piece below the upper corner piece ensures that both are aligned and accurately positioned. Then, the lower corner piece and the upper corner piece are fixedly connected using screws or other fasteners. Screw holes are usually pre-drilled at the connection point between the upper and lower corner pieces, and these screw holes are used to secure the connection. The purpose of this design is to create a robust connection structure capable of supporting the weight of the wall and ensuring its stability. This connection method not only enhances the strength of the joints between the corner pieces but also improves the stability of the entire wall system, allowing the wall to better withstand various external forces, such as earthquakes or impacts, after installation. Furthermore, this assembly method facilitates subsequent installation and adjustments, enabling quick disassembly and reassembly as needed, thus improving construction efficiency and flexibility.

[0105] Step S623: The insulation layer is filled at the connection between the upper and lower corner pieces. It should be noted that the insulation layer refers to the material layer filled in the wall structure to prevent heat transfer. In this invention, the insulation layer is mainly composed of rock wool. Rock wool is a high-quality thermal insulation material with good thermal insulation, fire resistance, and sound absorption properties, effectively improving the thermal insulation effect of the wall and meeting the building's requirements for wall insulation and fire resistance. Understandably, firstly, after the upper and lower corner pieces are connected and fixed, the rock wool is cut to a suitable size. This is to ensure that the rock wool can accurately fill the gaps at the corner piece connection, avoiding incomplete filling or material waste due to improper size. Its beneficial effect is improved filling efficiency and ensures the integrity of the insulation layer. Then, the cut rock wool is filled into the connection between the upper and lower corner pieces and compacted. This is because the rock wool needs to be in close contact with the corner piece to ensure the thermal insulation effect. Its beneficial effect is that it enhances the thermal insulation performance of the insulation layer, effectively prevents heat from being transferred through the corner joints, and improves the overall thermal insulation effect of the wall.

[0106] Step S624: Install the second gypsum board on both sides of the upper and lower corner pieces. The upper part of the second gypsum board abuts against the first gypsum board within the hanger structure, and the lower part of the second gypsum board abuts against the third gypsum board within the wall structure. It should be noted that the first gypsum board refers to the gypsum board installed on both sides of the upper part of the hanger to meet fireproofing and sound insulation requirements. It is usually installed above the hanger, providing initial fireproofing and sound insulation. The second gypsum board refers to the gypsum board installed at the connection between the hanger and the wall, used to cover the corner piece connection. It serves to seal and further enhance the fireproofing and sound insulation effects. The third gypsum board refers to the gypsum board installed inside the wall, abutting against the lower part of the second gypsum board. It is located inside the wall, providing internal support and fireproofing and sound insulation. Specifically, the materials of the first, second, and third gypsum boards are all gypsum board, but they can also be calcium silicate board, fiber-reinforced cement board, etc. Understandably, a second plasterboard is first installed on both sides of the upper and lower corner brackets at the connection between the hanger and the wall. The upper part of the second plasterboard fits tightly against the first plasterboard within the hanger structure, and the lower part fits tightly against the third plasterboard within the wall structure. This is done to ensure a complete seal at the connection between the hanger and the wall, preventing heat loss and noise transmission due to air circulation. The beneficial effects are a significant improvement in the wall's fire resistance and sound insulation, while also enhancing the overall structural stability.

[0107] In one embodiment of the present invention, the hanger structure includes a plurality of vertical hangers, and the step of passing the electromechanical equipment through the hanger structure and installing it to the floor slab includes passing the electromechanical pipes of the electromechanical equipment between adjacent vertical hangers of the hanger structure and installing the electromechanical pipes to the floor slab through connectors.

[0108] In this embodiment, it should be noted that step S30 includes step S31:

[0109] Step S31: The electromechanical pipes of the electromechanical equipment are threaded between adjacent vertical hangers of the hanger structure, and the electromechanical pipes are installed to the floor slab using connectors. It should be noted that threading the electromechanical pipes between adjacent vertical hangers of the hanger structure means threading the electromechanical equipment according to the spacing between adjacent vertical hangers within the hanger structure. The spacing between adjacent vertical hangers refers to the horizontal distance between two adjacent vertical hangers. In this invention, the spacing between adjacent vertical hangers is predetermined based on the structural design of the building and the layout requirements of the electromechanical equipment to ensure smooth threading of the electromechanical pipes. It is understood that connectors are auxiliary components used to fix the electromechanical pipes to the floor slab and securely connect them to the floor slab. These typically include expansion bolts, hooks, clamps, brackets, etc., and are not limited here, but are set according to specific needs. In this invention, the function of the connectors is to ensure that the electromechanical equipment is securely installed to the floor slab within the space between adjacent vertical hangers. Understandably, firstly, appropriate space is reserved between the two vertical hangers of the hanger according to the predetermined spacing between adjacent vertical hangers. This is to ensure sufficient space for the installation of electromechanical conduits and to avoid interference between the equipment and the hanger. Secondly, the electromechanical conduits are installed according to the spacing between adjacent vertical hangers. The conduits are installed into the reserved space of the hanger as designed. During installation, it is necessary to ensure that the conduits are correctly routed, securely connected, and comply with building codes and safety standards. This is because the correct installation of electromechanical conduits is crucial for the normal use of the building, ensuring the normal operation of power, communication, water supply, and drainage systems. This improves the reliability and safety of the electromechanical system and facilitates subsequent maintenance and repair. Specifically, the installation position of the connectors is determined based on the routing of the conduits and the spacing between adjacent vertical hangers. In one embodiment, expansion bolts or other connectors are used to fix the electromechanical equipment to the floor slab. In another embodiment, clamps or hooks are used to fix the electromechanical equipment to the floor slab. Clamps and hooks can tightly wrap around pipes to prevent displacement of mechanical and electrical equipment. No specific limitations are specified here.

[0110] In one embodiment of the present invention, the wall panel structure includes multiple prefabricated wall panels and gypsum board; the step of splicing the multiple prefabricated wall panels includes:

[0111] When there are gaps between the plasterboards of adjacent precast walls, fire-retardant adhesive is used to fill the gaps to complete the jointing process.

[0112] In this embodiment, it should be noted that this step is the first implementation method for joint treatment between multiple precast wall panels. This step includes S71, where, when there are gaps between the plasterboards of adjacent precast wall panels, fire-retardant adhesive is used to fill the gaps to complete the joint treatment. It is understood that when there are gaps between the plasterboards of adjacent precast wall panels, the construction workers will first carefully check the size and location of the gaps to ensure their uniformity and cleanliness. This is to ensure that the fire-retardant adhesive can fully fill the gaps, avoiding uneven filling or material waste due to gaps that are too large or too small. Secondly, using a professional fire-retardant adhesive filling tool, the fire-retardant adhesive is evenly injected into the gaps. During the filling process, it is necessary to ensure that the fire-retardant adhesive completely fills the gaps without leaving any voids. This effectively prevents air and fire sources from spreading through the gaps, enhancing the fire resistance of the wall. Finally, after the fire-retardant sealant is filled, the construction workers will use scrapers and other tools to smooth the sealant surface of the joints, making it flush with the wall surface. This not only improves the appearance but also prevents dust and debris from accumulating in the gaps, while also helping to improve the integrity and durability of the wall. This jointing method ensures a tight connection between multiple prefabricated wall sections, improving the wall's fire resistance and overall stability, while maintaining a clean and aesthetically pleasing surface, providing a good foundation for subsequent decorative work.

[0113] In one embodiment of the present invention, the wall panel structure includes multiple prefabricated wall panels and a fifth gypsum board; the step of splicing the multiple prefabricated wall panels further includes:

[0114] When manufacturing a single prefabricated wall panel in the factory, the left and right sides of the fifth gypsum board are each cut to a predetermined length so that the actual length of a single fifth gypsum board is less than the standard size, so as to reserve a joint position after the installation of two adjacent prefabricated wall panels.

[0115] After the prefabricated wall is installed on site, insulation boards that match the reserved joint size are filled at the joint positions.

[0116] The filled seams are then painted.

[0117] In this embodiment, it should be noted that this step is the joint treatment, a second implementation method for filling the joints of multiple prefabricated wall panels within the wall panel structure, and this step includes S72-S74:

[0118] Step S72: When manufacturing a single precast wall panel in the factory, the left and right sides of the fifth gypsum board are each cut to a predetermined length, so that the actual length of the single fifth gypsum board is less than the standard size, in order to reserve a joint space after the installation of two adjacent precast wall panels. It should be noted that when manufacturing a single precast wall panel in the factory, the left and right sides of the fifth gypsum board are first cut to a predetermined length, so that the actual length of the single fifth gypsum board is less than the standard size. The purpose of this is to reserve a joint space after the installation of adjacent precast wall panels. Specifically, for example, if the standard size of the fifth gypsum board for a single wall panel is 1200mm long, 150mm pieces can be pre-cut from both sides of the fifth gypsum board in the factory, at which point the actual length of the fifth gypsum board is 900mm. The reason for this is that after the fifth gypsum boards of the adjacent first and second walls are installed, a 300mm gap will naturally form between them, providing space for subsequent joint treatment. Then, after the wall is installed on-site, workers will cut 300mm pieces of plasterboard or cement board according to the actual situation and fill the joints. Subsequent painting and other processes will then be carried out to complete the joint treatment. This ensures the precision and aesthetics of the joint treatment, avoids dimensional errors caused by on-site cutting of plasterboard, and also improves construction efficiency, reducing on-site construction time and labor costs.

[0119] Step S73: After the precast wall panels are installed on-site, insulation boards that match the dimensions of the pre-reserved joints are filled at the joint locations. It should be noted that, firstly, after the precast wall panels are installed on-site, suitable insulation boards (such as gypsum board or cement board) are selected for filling based on the dimensions of the pre-reserved joints. Specifically, pre-cut insulation boards (such as gypsum board or cement board) are placed at the joint locations between adjacent precast wall panels, ensuring a tight fit between the insulation board and the joint, filling the gaps. This is done because the insulation board effectively fills the joints, preventing heat transfer through the gaps, thereby improving the wall's thermal insulation performance. Simultaneously, the insulation board also provides some sound insulation, reducing sound transmission and improving the wall's sound insulation effect. Secondly, after filling with the insulation board, the joints need to be treated to ensure the smoothness and aesthetics of the wall surface. This step typically includes sanding and painting the surface of the insulation board to integrate it with the wall surface. The purpose of this is to eliminate visual differences caused by the seams, making the entire wall look cleaner and more aesthetically pleasing. It also avoids potential problems like dust and stains accumulating at the seams, facilitating subsequent cleaning and maintenance. Finally, after the seam treatment is completed, the installation of the precast wall is essentially finished. This method of filling the seams with insulation panels not only improves the wall's thermal and sound insulation performance but also enhances its overall quality and lifespan, providing a more comfortable and quiet indoor environment for building occupants.

[0120] Step S74: Paint the filled joints. It's important to note that, firstly, when painting the filled joints, professional painting tools such as brushes or rollers should be used to evenly apply paint to the joints and the surrounding wall surface. This ensures the joints match the wall color for an aesthetically pleasing effect and also provides some protection against external environmental factors such as moisture and dust, thus extending the wall's lifespan. Secondly, during painting, ensure the paint thickness is moderate, avoiding both excessively thick and thin coats. Excessively thick paint may result in an uneven wall surface, affecting aesthetics; while insufficiently thin paint will not provide adequate protection. Finally, after painting, allow the paint to dry naturally, typically for a period of time, the specific time depending on the type of paint and environmental conditions. During the drying process, avoid touching or bumping the wall to prevent damage to the paint layer and affecting the final result. This painting process not only enhances the overall aesthetics of the wall but also strengthens its durability and protective properties, ensuring that the prefabricated partition wall remains in good condition during long-term use.

[0121] In one embodiment of the present invention, the preset length is 150mm, the standard size of a single fifth gypsum board is 1200mm, the actual length after cutting is 900mm, the reserved joint width after the installation of adjacent prefabricated walls is 300mm, and the size of the filling insulation board is 300mm.

[0122] In this embodiment, it should be noted that the insulation board can be gypsum board or cement board. First, during the prefabrication of the wall in the factory, the standard size of a single piece of fifth gypsum board (1200mm) is pre-cut, with 150mm removed from each side, resulting in an actual length of 900mm. This is done to reserve space for joints, allowing for a 300mm joint width between adjacent prefabricated wall panels during subsequent on-site installation. This reserved joint design effectively avoids deformation or cracking caused by overly tight wall installation, while also providing space for subsequent joint treatment, ensuring the integrity and aesthetics of the wall. Secondly, after installing adjacent precast wall panels on-site, a 300mm seam will be found between the two panels. A 300mm piece of gypsum board or cement board will be cut and used to fill the seam, then fixed in place. Filling the seam ensures the integrity of the wall, prevents air and sound from being transmitted through it, thereby improving the wall's sound insulation and heat insulation performance. It also facilitates subsequent painting and decoration work, making the wall surface smoother and more aesthetically pleasing. Finally, after filling the seam, the gypsum board or cement board will be painted and decorated to integrate it with the rest of the wall. The ultimate goal is to ensure that the entire precast wall meets design requirements in both function and appearance, guaranteeing the wall's practicality and stability while enhancing the overall aesthetics of the interior, achieving efficient installation and high-quality completion of the precast wall system.

[0123] In one embodiment of the present invention, the step of performing a flatness test on the ground of the frame structure and obtaining a judgment result includes:

[0124] The flatness of the ground of the frame structure is tested, and the judgment result is obtained;

[0125] When the judgment result is uneven, the target ground height data is determined based on the ground height data of the frame structure.

[0126] Based on the target ground height data, the ground of the frame structure is subjected to self-leveling processing, and the process of performing flatness detection on the ground of the frame structure and obtaining the judgment result is returned.

[0127] If the judgment result is flat, proceed to the next step.

[0128] In this embodiment, it should be noted that the method includes steps S41-44:

[0129] Step S41: Perform a flatness test on the ground of the frame structure to obtain a judgment result. It should be noted that the flatness test refers to the precise measurement of the flatness of the ground within the frame structure to determine whether it meets construction requirements. This flatness test is to ensure the smooth progress of subsequent installation procedures and avoid installation errors and quality problems caused by uneven ground. It is understood that this embodiment uses a laser level to scan the ground from all directions. The laser level can emit one or more horizontal laser lines, and the contact points between these laser lines and the ground can accurately measure the elevation and undulation of the ground. Next, the measured data is compared with the construction standard. In this embodiment, the construction standard is to use a 2-meter straightedge for testing, with an allowable deviation of ≤2mm / 2m (for the base leveling layer).

[0130] Step S42: When the judgment result indicates unevenness, the target ground height data is determined based on the ground height data of the frame structure. It should be noted that the target ground height data refers to the actual ground height data after adjustment following the completion of the concrete frame structure construction at the construction site. The judgment result is obtained by comparing the data with the previous step. It can be understood that determining the target frame structure's ground height data based on the judgment result, i.e., the adjusted actual ground height data, is used to guide subsequent work such as the construction of the self-leveling platform and the installation of the base trench. This effectively ensures the flatness and construction accuracy of the ground, creating favorable conditions for the smooth installation of the target precast wall panels.

[0131] Step S43: Based on the target ground height data, perform self-leveling treatment on the ground of the frame structure, and return to the step of performing flatness detection on the ground of the frame structure to obtain the judgment result. It should be noted that self-leveling treatment refers to a ground leveling process. Using self-leveling materials (usually cement-based or epoxy resin-based materials), after being poured onto the ground, the material can automatically flow and level, forming a flat, smooth, and seamless ground surface. This step is understood to address unevenness and differences in levelness on the ground after construction, requiring correction on the initial frame structure ground, i.e., creating a self-leveling platform to obtain a higher-quality finished surface. Finally, a professional flatness detection tool (such as a laser level) is used to detect the flatness of the ground to ensure that the flatness meets the construction requirements. The flatness detection of the frame structure ground is repeated to ensure that the ground ultimately meets the construction requirements.

[0132] Step S44: If the judgment result is flat, proceed to the next step. It should be noted that the target trench structure refers to the trench structure installed and fixed to the frame structure floor after the ground has been judged to be flat. This means that the trench structure is fixed to the frame structure floor, and the through hole in the middle of the trench is connected to the building floor using fasteners such as bolts or rivets, ensuring that the trench is firmly installed and accurately positioned. The purpose of this is to provide a stable and precise support foundation for the subsequent installation of precast walls, avoiding deviations in wall installation due to uneven ground, thereby improving construction quality, reducing subsequent adjustments and corrections, and increasing construction efficiency.
