Description

Technical Field

[0001] This application relates to the field of prefabricated housing, and in particular to a composite panel unit housing structure and its installation method. Background Technology

[0002] Prefabricated housing assembly, also known as prefabricated construction or modular construction, refers to a construction method in which building components are prefabricated in a factory and then transported to the construction site for assembly. It features short construction cycles, high quality, resource conservation, and ease of maintenance. It allows for DIY prefabrication in the factory according to customer requirements, followed by on-site assembly, offering flexible design options to meet diverse needs.

[0003] However, due to the large number of panels and connecting parts that need to be assembled, and the fact that each part requires precise alignment to ensure that the structures fit together, an experienced construction team is needed or the assembly time needs to be extended, otherwise the overall construction cycle will be prolonged. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite panel unit house structure and its installation method.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In the first aspect, this application provides a composite panel unit house structure, which adopts the following technical solution:

[0007] A composite panel unit house structure includes a panel body, which is used to form wall panels and / or roof panels. The panel body is connected to the foundation by a bottom constraint. Adjacent panel bodies are connected by a middle constraint and a top constraint. The top constraint is provided with a self-locking connector, which is connected to the panel body. The panel body has a connecting groove in its circumference. The bottom constraint, middle constraint, and top constraint are fixedly connected by bolts after sliding and engaging with the connecting groove.

[0008] The beneficial effects are as follows: the bottom constraint enables rapid positioning and fixation of the main body of the panel to the foundation; the middle constraint strengthens the connection between adjacent main bodies of the panel; and the top constraint quickly locks the top of adjacent main bodies of the panel through self-locking connectors to prevent misalignment. In the entire structure, the three constraints work together to form a three-dimensional stable system, ensuring the overall stability of the building and installation accuracy. The design of the connecting grooves and connecting protrusions facilitates guiding positioning during installation, significantly improving installation efficiency.

[0009] Preferably, the central constraint includes corner posts and / or upright posts, the corner posts being located at the included angle between adjacent plate bodies, and the upright posts being located at the side connection of adjacent plate bodies; both the corner posts and the upright posts have connecting protrusions on their side walls that mate with connecting grooves on the plate bodies.

[0010] The beneficial effects are as follows: corner posts not only serve as connecting components but also as corner supports for buildings, improving the structural strength of the building corners; uprights are used to strengthen the side connections of the main body of the panels, enhancing the overall load-bearing capacity and resistance to lateral displacement. The cooperation between the connecting protrusions and connecting grooves enables rapid positioning and fixation.

[0011] Preferably, the top constraint is a top pressure beam, the self-locking connector is slidably engaged with the top pressure beam, and the self-locking connector and the top pressure beam are fixedly connected by a sliding positioning member.

[0022] S5 Wall Panel and Post Installation: First, slide the bottom connecting groove of the first wall panel into the bottom pressure beam. Then, push the first wall panel so that the connecting groove on its side connects to the corner post. Next, install the post on the side of the first wall panel. The bottom of the post is connected to the foundation using M12 chemical anchors, and the side of the post is fixedly connected to the first wall panel. Then, connect the second wall panel to the bottom pressure beam and corner post in sequence.

[0023] S6 installs the top constraint, which is slidably placed in the connecting groove on the top of the wall panel. The first connecting part is fixedly connected to the first wall panel, the connecting part is fixedly connected to the top of the corner post or column, the second connecting part is fixedly connected to the top of the second wall panel, and so on, until the wall installation is completed.

[0024] S7 Corner Post Decorative Panel Installation: After the wall panel installation is complete, it is sealed using decorative panels. The decorative panels are installed to the exposed side of the corner post using self-tapping screws, and sealant is applied between the decorative panels and the wall panel. Structural adhesive is used to seal between adjacent decorative panels; the decorative panels are made of calcium silicate board.

[0047] The following is in conjunction with the appendix Figure 1 -Appendix Figure 17 This application will be described in further detail.

[0048] This application discloses a composite panel unit house structure and its installation method.

[0049] A composite panel unit house structure includes a panel body 1, which is used to form wall panels and / or roof panels. When the panel body 1 is used as a wall panel, the connection between adjacent wall panels and the connection between the wall panels and the foundation are realized through the wall panel connection structure. When the panel body 1 is used as both a wall panel and a roof panel, the connection between the wall panels and the roof panel is realized through the roof panel connection structure.

[0050] The installation method for composite panel unit house structure is as follows: S1 pour the foundation; S2 lay out and position the anchor bolts;

[0051] S3 Install corner post 31; S4 Install bottom constraint 4 and corner post 31; S5 Install wall panel and column 33; S6 Install top constraint 2; S7 Install decorative panel of corner post 31; S8 Install roof panel.

[0052] The main body 1 of the panel includes a frame, pressure strips 12 on both sides of the frame, and panels 13 on the sides of the pressure strips 12. The edges of the pressure strips 12 extend beyond the frame to form a tolerance edge 14. A fireproof and heat-insulating core layer is filled between adjacent panels 13 and the frame. The frame is a metal frame 11. A connecting groove 15 is formed by combining the metal frame 11 as the bottom edge and the tolerance edge 14 as the side. The connecting groove 15 is a 20mm*40mm groove, and the main body 1 of the panel has connecting grooves 15 around its circumference. The connecting grooves 15 can cooperate with the connection structure of the wall panel, facilitating processing, finishing, and installation positioning.

[0053] The panel 13 is glued to the pressure strip 12, and the pressure strip 12 is glued to the metal frame 11.

[0054] The bottom edge of the connecting groove 15 has a pre-drilled wall panel connecting hole 16. The wall panel connecting hole 16 is an oblong hole. A pad 19 is glued to the bottom edge of the connecting groove 15. The pad 19 serves to absorb shock.

[0055] The metal frame 11 is a quadrilateral frame formed by four tubing connected end to end. The quadrilateral frame can be rectangular or a right-angled trapezoidal structure. The rectangular metal frame 11 serves as a standard unit structure for wall panels or roof panels. Because some areas experience frequent snow or rain, such as the snowy regions of northern Europe and America where sloping roofs are common, the top of the wall needs to be angled to accommodate the sloping roof. In this case, the metal frame 11 for some wall panels requiring an angled top is a right-angled trapezoidal structure.

[0056] Once the roof slope is determined, the width of the trapezoidal metal frame 11 is fixed, and the length of the pipe at the top of the metal frame 11 can be obtained, thus achieving standardization.

[0057] The standard roof slope used in this embodiment is 27 degrees.

[0058] The metal frame 11 also includes a reinforcing keel 17, with both ends of the reinforcing keel 17 connected to two opposing pipes. The reinforcing keel 17 is made of the same material as the metal frame 11 and is mainly used to further improve the strength of the main body 1 of the sheet metal.

[0059] The pipe is a steel pipe with a rectangular cross-section. When the main body of the plate 1 is used as a wall, the standard modular dimensions of the main body of the plate 1 are 1120mm*2500mm*80mm.

[0060] When the main body 1 of the panel is used as a roof panel, the main body 1 of the panel has pre-drilled roof panel connection holes 18. The roof panel connection holes 18 are connected through M8 hot-melt drill holes. The standard modular dimensions of the main body 1 of the panel when used as a roof panel are 1120mm*3100mm*80mm. The roof panel connection holes 18 can be adjusted according to the connection position of the roof panel.

[0061] Panel 13 is made of 5mm calcium silicate board (SK board), and pressure strip 12 is also made of calcium silicate material, with a thickness of 15mm and a width of 60mm. Pressure strip 12 provides fire resistance. The main body 1 of the board, from the outside to the inside, consists of: two 5mm calcium silicate structural boards on the inner and outer sides, a 15mm calcium silicate fireproof pressure plate, and a metal frame 11 formed by connecting 40*2mm steel pipes end to end. The pad 19 is 1mm thick vibration-damping rubber, providing shock absorption. This pad 19 surrounds the outer perimeter of the metal frame 11. Through this metal frame 11, the main body 1 of the board can bear a load of 1300 MPa. Therefore, compared with wood-plastic composite profiles, its load-bearing strength is much higher.

[0062] The fireproof and thermal insulation core layer is integrally filled with polyisocyanurate (PIR) foam material. The panel 13, the PIR fireproof and thermal insulation core layer, and the metal frame 11 are bonded together using adhesive.

[0063] The advantages of the plate body in this application are: 1. Optimized structural force transmission (steel frame); 2. Material selection (calcium carbonate board); 3. Edge overhang design, also known as anti-misalignment edge. This design concept can realize the design of secondary processing allowance, and use the anti-misalignment edge and metal frame 11 to form a connecting groove 15. The connecting groove 15 can be connected with the wall panel connection structure, thereby improving the overall structural stability.

[0064] Through comprehensive innovation in structural design, material selection, and process adaptability, key technical challenges such as insufficient sheet strength, poor dimensional stability, low on-site milling accuracy, and high risk have been effectively solved.

[0065] Fundamentally optimized force transmission path: An innovative three-tiered load-bearing mechanism is adopted: "slab load → built-in high-strength steel frame structure → load-bearing columns," completely breaking through the inefficient traditional precast slab model that relies on the slab's own material strength to directly transmit loads. The steel frame, with its excellent bending, compressive, and shear strength characteristics, serves as the core load-bearing skeleton, efficiently bearing and distributing various static loads (such as self-weight and equipment weight), dynamic loads (such as personnel movement loads), and potential impact loads transmitted from the slab surface.

[0066] Maximizing Material Potential: Through this structural design, the composite panel surface layer (calcium carbonate board) mainly undertakes the functions of enclosure, division, and transfer of force to the internal frame, without needing to have extremely high self-load-bearing strength; while the steel frame fully utilizes its high strength and toughness material advantages to bear the main axial and bending stresses. Thus, while maintaining a low overall self-weight of the panels (facilitating transportation and hoisting), a leapfrog improvement in the overall load-bearing capacity of the panels (especially bending stiffness, ultimate load-bearing capacity, and load-bearing efficiency) is achieved, significantly broadening its application range in building parts with high load-bearing requirements (such as large-span floor slabs and equipment support walls).

[0067] Rationalized stress distribution: The load is transferred to the steel frame through multiple points or evenly on the slab surface, and then transferred to the building's load-bearing structure (columns / walls) through the strong beam-column joints of the steel frame. This greatly reduces the risk of deformation or failure caused by local stress concentration on the slab surface, and enhances the safety and durability of the structure.

[0068] Dimensional stability and environmental adaptability are greatly enhanced, reducing the need for on-site adjustments:

[0069] The steel frame structure provides strong constraints: the built-in high-strength steel frame not only provides load-bearing capacity, but its material itself also has an extremely low coefficient of thermal expansion and excellent dimensional stability. Even when transported over long distances through different climate zones with significant temperature and humidity variations, the steel frame provides strong geometric constraints on the overall panel material, greatly suppressing and offsetting the linear dimensional changes that the outer cladding material (such as calcium carbonate board, which, due to its mineral composition, has a certain degree of expansion and contraction with moisture, but whose deformation range is controllable) may exhibit under the influence of environmental temperature and humidity.

[0070] Significantly reduced dimensional deviation accumulation: Compared with traditional boards without strong internal rigid constraints, the composite board of this invention has significantly reduced the cumulative dimensional deviation after being transported to the site (such as length, width, diagonal errors, etc.), which significantly improves the retention rate of the board's dimensional accuracy after leaving the factory in complex transportation environments. This greatly reduces the occurrence of on-site assembly difficulties due to dimensional deviations, reduces the reliance on secondary processing such as on-site milling and shaping, and fundamentally improves the convenience and reliability of installation.

[0071] Revolutionary improvements have been made in on-site milling machinability, protection, and accuracy:

[0072] Specially formulated panel materials ensure convenient processing: Calcium carbonate board (or inorganic pre-coated decorative board) is selected as the surface layer. This material not only possesses excellent physical properties (fireproof, moisture-proof, and weather-resistant), but also has a uniform internal structure, fine texture, and moderate hardness, exhibiting excellent machinability (easy cutting). Using a standard handheld milling machine, smooth, low-noise, dust-free milling (an environmentally friendly advantage) and high-quality milling with smooth edges (high milling finish, less prone to chipping and breakage) can be performed on-site, significantly improving processing efficiency and reducing the skill requirements for operators.

[0073] Unique edge overhang design provides key physical protection: One of the core design highlights of this design is that the outer edge of the calcium carbonate board is set to exceed the preset safety distance of the internal steel frame (e.g., 3mm - 10mm) on all four sides, forming a "millable overhang area" around the board.

[0074] Intrinsic Safety Protection: This design creates a natural, clearly defined, and physically visible "processing isolation zone" or "buffer zone" between the calcium carbonate board and the internal steel frame. Whether the milling depth is adjusted to a preset level or there are processing deviations due to parallax or operational fluctuations, any milling operation at a normal depth will only affect the overhanging edge area of ​​the calcium carbonate board, without touching the internal load-bearing steel frame. This design eliminates all possibilities of accidentally cutting the steel frame at its physical source, completely resolving the fatal quality risks (damage to structural components) associated with on-site milling operations.

[0075] High operational tolerance: Even with certain operational errors, the core load-bearing structure will not be damaged, reducing operational risks and improving construction safety.

[0076] Synergistic Material Combinations and Complementary Performance: A high-strength, high-toughness steel frame is combined with lightweight, high-hardness, flame-retardant, and moisture-proof calcium carbonate boards through a scientifically reliable connection process (such as structural adhesive bonding + pre-embedded connectors), forming a stable whole that combines rigidity and flexibility. The steel frame provides "rigid performance" such as impact resistance and deformation resistance, while the calcium carbonate boards provide excellent "functional performance" such as fire resistance, moisture resistance, sound insulation, and easy cleaning and maintenance. The combination of the two significantly improves the overall service life and long-term performance stability of the composite board, especially showing its advantages in harsh environments.

[0077] Component integrity assurance: Avoiding milling damage, the steel frame itself ensures that all prefabricated welding points, bolt holes, wiring holes and other key interfaces and functional points are in good condition, maintaining the original intent and integrity of the prefabrication design.

[0078] Simplified installation process: Small dimensional deviations reduce adjustment time, and high-precision milling allows for quick and convenient achievement of ideal joints, greatly improving the efficiency of on-site hoisting, splicing, and fixing.

[0079] Reducing the risk of quality incidents: Eliminating the risk of damage to core components means reducing rework, replacement, and even potential structural safety issues, ensuring the project schedule and reducing overall costs.

[0080] Optimized overall transportation and installation costs: The lightweight design maintains good performance while significantly increasing load-bearing capacity, meaning less material or load-bearing components can be used for the same load requirements; improved dimensional accuracy reduces manpower and time costs for on-site adjustments; and it avoids waste caused by processing errors. Therefore, from a life-cycle perspective (manufacturing, transportation, installation, and maintenance), it has significant cost-effectiveness advantages and economic potential.

[0081] The wall panel connection structure is connected to the wall panel through the connection groove 15. The connection structure includes a bottom constraint 4 located on the foundation and connected to the bottom of the wall panel, a middle constraint 3 located on the foundation and connected to the side of the wall panel, and a top constraint 2 located on the top of the wall panel and connected to the adjacent wall panel. The bottom constraint 4 is fixed along the horizontal direction of the foundation and slides in fit with the connection groove 15. The middle constraint 3 is fixedly connected along the vertical direction of the foundation and is fixedly fitted with the connection groove 15.

[0082] Bottom constraint 4 is a bottom pressure beam, which is fixedly connected to the foundation by bolts.

[0083] The central constraint 3 consists of corner posts 31 and / or upright posts 33. Both corner posts 31 and upright posts 33 have connecting protrusions 36 on their side walls that mate with connecting grooves 15 on the main body of the panel 1. The upper and lower ends of the standard upright posts 33 or corner posts 31 are identical, and the connecting protrusions 36 have single-sided locking holes for the wall panel; the number of locking holes corresponds to the modular number of connecting holes 16 in the wall panel.

[0084] Angle posts 31 are positioned at the included angle between adjacent main body panels 1. Each angle post 31 has two adjacent surfaces with connecting protrusions 36, which are fixedly engaged with the connecting grooves 15 of the wall panels. When two wall panels are perpendicular to each other and connected, they are connected via the two connecting protrusions 36 of the angle post 31.

[0085] The corner post 31 has an L-shaped cross-section and is equipped with multiple L-shaped reinforcing plates 32 that are adapted to it. There are multiple L-shaped reinforcing plates 32, which are respectively set at the upper and lower ends of the corner post 31. The L-shaped reinforcing plate 32 set at the upper end of the corner post 31 can be fixedly connected to the top constraint 2, and the L-shaped reinforcing plate 32 set at the lower end of the corner post 31 can be fixedly connected to the foundation through chemical anchors.

[0086] The column 33 is set at the side connection of the adjacent main body 1 of the plate;

[0087] The column 33 is divided into two types. One type of column 33 has two opposing connecting protrusions 36, which are mainly used to connect two parallel wall panels. The two connecting protrusions 36 are respectively fixedly connected to the connecting grooves 15 of the two adjacent wall panels. The other type of column 33 has three connecting protrusions 36, which are mainly used to connect three wall panels. The three connecting protrusions 36 are respectively fixedly connected to the connecting grooves 15 of the three adjacent wall panels.

[0088] The column 33 with three adjacent connecting protrusions 36 has a T-shaped cross section. The column 33 is provided with multiple T-shaped reinforcing plates 35 that are adapted to it. There are multiple T-shaped reinforcing plates 35, which are respectively set at the upper and lower ends of the column 33. The T-shaped reinforcing plate 35 set at the upper end can be fixedly connected to the top constraint 2, and the T-shaped reinforcing plate 35 set at the lower end can be fixedly connected to the foundation by chemical anchors.

[0089] Similarly, the column 33 with two connecting protrusions 36 has a rectangular cross-section. In this application, the size of the column 33 with two connecting protrusions 36 is exactly the sum of the connecting grooves 15 of two adjacent walls. The column 33 is provided with multiple rectangular reinforcing plates that are adapted to it. There are multiple rectangular reinforcing plates, which are respectively set at the upper and lower ends of the column 33. The rectangular reinforcing plate set at the upper end can be fixedly connected to the top constraint 2, and the rectangular reinforcing plate set at the lower end can be fixedly connected to the foundation through chemical anchors.

[0090] The top constraint 2 includes a connecting portion 21, a first connecting portion 22 fixedly connected to the connecting portion 21, and a second connecting portion 23 fixedly connected to the connecting portion 21. The first connecting portion 22 is fixedly engaged with the connecting groove 15 of the wall panel, and the second connecting portion 23 is fixedly engaged with the adjacent wall panel. The first connecting portion 22 and the second connecting portion 23 are respectively connected to two adjacent sides of the connecting portion 21. The first connecting portion 22 and the second connecting portion 23 are respectively connected to two opposite sides of the connecting portion 21. The connecting portion 21 is fixedly connected to the middle constraint 3.

[0091] Top constraint 2 is divided into three types;

[0092] The first type is where the first connecting part 22 and the second connecting part 23 are perpendicular to each other in the horizontal projection. In this case, the top constraint 2 is a corner pressure beam, which is set on the corner column 31.

[0093] The second type is where the first connecting part 22 and the second connecting part 23 are located on the same extension line, and the top constraint 2 is a flat pressure beam or an inclined pressure beam. The flat pressure beam is set on the wall where the metal frame 11 has a rectangular structure, and the inclined pressure beam is set on the wall where the metal frame 11 has a right-angled trapezoidal structure.

[0094] The third type is where the extension lines of the first connecting part 22 and the second connecting part 23 intersect. The top constraint 2 is a ridge beam, which is set on two symmetrical walls at the ridge, and the metal frame 11 of the wall is a right trapezoidal structure.

[0095] First, using bottom constraint 4, bidirectional initial positioning is achieved: The bottom pressure beam is pre-installed in the foundation, forming natural physical baselines in the X direction (length direction of the wall panel) and Y direction (depth direction of the wall panel). During wall panel hoisting, gravity naturally positions the panel into the bottom pressure beam, achieving millimeter-level planar positioning accuracy. This completely eliminates the drift error caused by traditional "manual visual inspection + repeated adjustments".

[0096] Self-correcting mechanism: The bottom pressure beam is inserted into the connecting groove 15 of the wall panel, which can automatically correct slight angular deflections during the lowering of the wall panel, forming a natural anti-torsion design and greatly reducing the stringent requirements for hoisting operation precision. It forms hard constraints in the X and Y directions, so no additional planar limiting support (such as traditional diagonal bracing) is needed after the wall panel is in place, reducing the on-site support system by more than 60%.

[0097] Corner post 31 and column 33 serve as the core components for ensuring verticality, enabling Z-axis stiffness enhancement: Column 33 acts as the backbone of the overall structural stiffness, with pre-embedded connectors (such as steel brackets and anchor bolt sleeves) embedded in the wall panel for rigid anchoring, forming an efficient force transmission path. This allows for active leveling of the wall panel in the Z-direction (height / verticality), ensuring that the overall verticality deviation of the wall facade is ≤1 / 1000.

[0098] As a third-party reference point independent of the wall panels, column 33 can transfer the standard line layer by layer. Through the plumb correction of column 33 itself, each wall panel is installed with the same column 33 as the reference, completely preventing the accumulation of errors between individual panels in the traditional assembly mode.

[0099] The column 33 and the wall panel form a lateral force resisting frame system, which significantly improves the transmission efficiency of horizontal loads (wind load / earthquake) compared to the pure plate joint connection scheme, and increases the structural damping ratio by about 40%.

[0100] The top constraint 2 enables flatness control. The first connecting part 22 and the second connecting part 23 span the top of the adjacent wall panels, and the top edge of the wall panels is locked into a whole by bolts or welds, forming an "anti-displacement bridge". This completely eliminates the micro-slippage (misalignment / separation ≤ 0.3mm) of the top of the wall panels caused by factors such as self-weight settlement, concrete creep, and wind-induced vibration.

[0101] Overall planar stiffness enhancement: The top connecting plate and the bottom guide rail form a double-layer enclosure constraint, allowing multiple wall panels to share the load collaboratively and significantly improving the overall in-plane stiffness. This prevents local buckling of the wall under asymmetric loads.

[0102] This structure constructs a spatial orthogonal rigid constraint chain with bottom constraint 4 (controlling the plane), middle constraint 3 (controlling the vertical), and top constraint 2 (controlling misalignment), fundamentally reconstructing the underlying logic of precast wall panel installation. Its technological value is not only reflected in the exponential increase in construction speed and precision, but also in three innovative mechanisms: mechanical guidance replacing manual operation, system constraints eliminating error accumulation, and rigid closed-loop termination of micro-displacement transmission.

[0103] Both the first connecting part 22 and the second connecting part 23 are sheet metal, which is bent to form a bent wall. The roof panel connecting structure is set on the bent wall.

[0104] A roof panel connection structure includes a self-locking connector 5 that slides with the top of a wall panel, a sliding positioning member 6 that restricts the movement of the self-locking connector 5 and the wall panel, and a connecting bolt 7 that passes through the roof panel and engages with the self-locking connector 5. The self-locking connector 5 has a self-locking hole 54 through which the connecting bolt 7 passes.

[0105] The self-locking connector 5 is bent to form an abutment portion 51, and a self-locking hole 54 is formed in the abutment portion 51. The abutment portion 51 is parallel to the roof panel, allowing it to make surface contact with the lower surface of the roof panel after installation, thus improving the support effect.

[0106] The self-locking connector 5 has a bending part 52 and a connecting part 53. The two ends of the bending part 52 are connected to the abutting part 51 and the connecting part 53 respectively. The connecting part 53 is fixedly connected to the wall through the sliding positioning part 6.

[0107] The force borne by the roof panel will be transmitted sequentially through the abutment part 51, the bending part 52 and the connecting part 53 to the wall panel or the middle restraint 3, and finally to the foundation.

[0108] The sliding positioning member 6 includes a clamping piece 61 and a clamping bolt 62. The end of the clamping bolt 62 passes through the clamping piece 61 and is connected to the self-locking connector 5. The wall panel has a bent wall 24 located between the clamping piece 61 and the self-locking connector 5.

[0109] The clamping bolt 62 is fixedly connected to the self-locking connector 5 by a nut.

[0110] An anti-loosening washer 63 is provided between the nut and the self-locking connector 5.

[0111] A roof panel is composed of a main body 1 of a board material. The main body 1 of the board material has pre-drilled roof panel connection holes 18. Connecting bolts 7 pass through the roof panel connection holes 18 and are fixedly connected to the self-locking connectors 5.

[0112] The diameter of the roof panel connection hole 18 is larger than the thread of the connecting bolt 7 but smaller than the thread head of the connecting bolt 7.

[0113] During installation, the self-locking hole 54 is aligned with the roof panel connection hole 18, and the main body of the panel 1 is fixedly connected to the self-locking connector 5 by connecting bolts 7.

[0114] The specific installation method is as follows

[0115] S1 is a foundation for pouring a standardized 250mm raft foundation;

[0116] S2 Layout and Positioning Anchors: After the foundation is completed, the layout and positioning are used to form horizontal and vertical baselines.

[0117] S3 Install Angle Post 31: Install Angle Post 31 to the position of M16 Chemical Anchor.

[0118] S4 Installation of Bottom Constraints 4 and Corner Posts 31: The bottom pressure beams are arranged horizontally along the transverse or longitudinal direction of the baseline and fixed to the foundation using M4.5 expansion bolts. Precast pressure beam connection holes.

[0119] S5 Installation of Wall Panels and Posts 33: First, slide the bottom connecting groove 15 of the first wall panel into the bottom pressure beam. Then, push the first wall panel so that the connecting groove 15 on the side of the first wall panel connects with the corner post 31. Next, install the post 33 on the side of the first wall panel. The bottom of the post 33 is connected to the foundation through M12 chemical anchors, and the side of the post 33 is fixedly connected to the first wall panel. Then, connect the second wall panel to the bottom pressure beam and the corner post 31 in sequence.

[0120] The S5 installation is achieved through a three-step process: hoisting and lowering (guide rail for XY positioning) → connecting the column 33 (Z-axis leveling and anchoring) → locking the top plate (anti-displacement reinforcement). These three steps complete the high-precision installation.

[0121] S6 Install the top constraint 2. The top constraint 2 is slidably set in the connecting groove 15 on the top of the wall panel. The first connecting part 22 is fixedly connected to the first wall panel, the connecting part 21 is fixedly connected to the top of the corner post 31 or the column 33, the second connecting part 23 is fixedly connected to the top of the second wall panel, and so on to complete the wall installation.

[0122] S7 Installation of Corner Post 31 Decorative Panels: After the wall installation is complete, the decorative panels are used for sealing. The decorative panels are installed to the exposed side of Corner Post 31 using self-tapping screws, and sealant is applied between the decorative panels and the wall panel. Structural adhesive is used to seal between adjacent decorative panels; the decorative panels are made of calcium silicate board.

[0123] S8 Roof Panel Installation: Roof panel connection holes 18 are pre-drilled in the roof panel, and a self-locking connector 5 is provided on the top pressure beam. The self-locking connector 5 is clamped and fixed to the bent wall 24 by the sliding positioning component 6. The self-locking connector 5 is also provided with a self-locking hole 54. During the hoisting of the roof panel, the roof panel connection hole 18 is aligned with the self-locking hole 54 on the self-locking connector 5. Then, the connecting bolt 7 passes through the self-locking hole 54 and the roof panel connection hole 18 to achieve a fixed connection between the roof panel and the wall panel.
