They are assembled and installed on site through reliable connection methods. Prefabricated buildings have the advantages of energy saving, environmental protection, and short construction period.

[0003] Existing prefabricated walls mostly use prefabricated concrete frames and walls, which are transported to the construction site with prefabricated beams, columns and floor slabs, and then re-reinforced, molded, cast in place, slow setting, demolded, repaired, and finally completed with plastering. Not only are there many processes, heavy weight, wet operations, a lot of garbage, and low efficiency, but the cost is also not low. However, due to the shortcomings of lightweight materials in wind resistance, compression resistance, shear resistance and earthquake resistance, it is difficult to use them for exterior walls; traditional prefabricated walls are relatively bulky and inconvenient to transport. During the assembly process, the difficulty of assembly is increased, affecting assembly efficiency. There are also some lightweight walls on the market, but lightweight walls are prone to insufficient strength due to their thin walls, and insufficient comfort levels such as thermal insulation and sound insulation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 4 As shown; A method for forming an exterior wall with a multi-layer wall panel and a steel structure comprises the following steps: S1. Preparation of H steel frame 20; specifically: S1.1 According to the design dimensions, cut the H steel of the design length; S1.2 Butt the H-steel according to the designed orientation to form the exterior wall frame and label the H-steel; S1.3 Drill holes at the H-steel joints and install them with bolts to form an H-steel frame 20; S1.4 Remove the H steel frame 20, move it into the transport carriage, and move it to the construction site; S2. Preparation of wallboard 10; specifically: S2.1 preparing a wall panel 10 including an exterior wall layer 11 and an interior wall layer 11; S2.2 Insert the prepared wall panels 10 into the C-shaped steel in sequence, so that the C-shaped steel covers the top and bottom of the wall panels 10, and cut the C-shaped steel according to the designed size; S2.3 embedding prefabricated windows and prefabricated doors on the spliced ​​wall panels 10; S2.4 remove the prefabricated windows, prefabricated doors and wall panels 10 and load them for transportation; S3. Transport the prefabricated wall to the installation site; S4. On-site assembly; S4.1. Install the H steel frame 20 on site, prevent the lower beam from being on the foundation, insert the column into the reserved hole on the foundation, connect the lower beam and the column, pour concrete mortar on the reserved hole, and complete the construction of the column and the lower beam; S4.2 Install steel buckles 3 on both sides of the column using bolts; S4.3 Insert the wall panels 10 between the steel buckles 3 of the columns in sequence, insert the plate fixing angle steel into the gap between the lower beam and the wall panel 10, fix the plate fixing angle steel 4 and the lower beam with bolts, adjust the surface flatness of the wall panel 10, and finally fix the wall panel 10 and the plate fixing angle steel 4 with bolts; S4.4 Press the upper beam onto the top of the wall panel 10 and fix it with bolts and columns; S4.5 Insert the plate fixing angle steel 4 into the gap between the upper beam and the wall panel 10, fix the plate fixing angle steel 4 and the upper beam with bolts, and then fix the wall panel 10 and the plate fixing angle steel 4 with bolts; S4.6 Waterproof the joints; S4.7 Perform surface treatment on the wall.

[0024] In this embodiment: The present invention uses H-steel as a frame and load-bearing structure to construct an efficient and stable prefabricated building solution. H-steel not only provides a strong load-bearing capacity, but also its structural form enables the entire building to have good earthquake resistance. Steel buckles 3 are fixed on both sides of the frame to accurately limit the wall panels 10, which can effectively prevent misalignment or tilting during construction or use. At the same time, the fixed plate angle steels 4 fixed on the upper and lower beams further enhance the stability of the wall panels 10, ensuring that they can maintain a good shape when subjected to external forces or environmental changes.

[0025] Wherein, S2.1 prepares the wall panel 10 including the outer wall layer 11 and the inner wall layer 13, specifically comprising: S2.11 The wall panel 10 uses a rock wool board as the middle layer 12, the rock wool board is cut according to the design size, and the surfaces on both sides are roughened; S2.12 The rock wool board is clamped in the middle of the mold, and after roughening, an outer wall layer 11 is cast on the surface of one side, and an inner wall layer 13 is cast on the other side to form a wall panel 10.

[0026] In this embodiment: For the warmer areas in the south, the wall panel 10 can use an outer wall layer 11 cast by ceramsite concrete and an inner wall layer 13 cast by aerated concrete. This design makes the wall panel 10 have excellent shear resistance as a whole, and the weight is greatly reduced. The outer wall layer 11 of ceramsite concrete; For the colder areas in the north, the wall panel 10 adopts a three-layer structure design of a sandwich structure of an outer layer of ceramsite concrete-a rock wool middle layer insulation-aerated concrete inner layer. The outer layer is made of high-strength material, and the middle layer 12 uses rock wool with excellent sound insulation and thermal insulation performance. This three-layer structure not only reduces the overall weight of the wall, facilitating transportation and installation, but also ensures excellent thermal insulation and sound insulation, providing residents with a warm and quiet indoor environment. This combination of lightweight and high strength enables the wall panel 10 to meet higher functional requirements in modern buildings.

[0027] The wall panel 10 of the present invention is designed as a detachable module with a length of less than 6 meters, which is convenient for manufacturing, transportation and on-site installation. This modular design greatly improves the flexibility and efficiency of construction. In the actual assembly process, the upper and lower sides of the wall panel 10 are clamped and fixed by using C-shaped steel, combined with the installation of the fixing plate angle steel 4, and fixed by using bolts passing through the C-shaped steel to form a larger whole. In this way, during the hoisting stage, a larger area of ​​wall can be effectively assembled at one time, greatly reducing the process and time in the construction.

[0028] During the hoisting process, the wall panel 10 and the C-shaped steel can be calibrated and installed with the help of laser ranging, radar positioning, manipulators, etc. The wall panel 10 and the C-shaped steel are inserted into the H-steel frame 20 together, and the fixing plate angle steel 4 and the H-steel frame 20 are connected by bolts, and the steel buckle 3 and the wall panel 10 are connected at the same time to ensure the firmness of the entire structure. This connection method not only improves the overall stability of the structure, but also simplifies the assembly process, making on-site construction more efficient. When the assembly of a layer of the building is completed, a new H-steel frame 20 can be docked on the top of the H-steel frame 20, and then the above assembly steps are repeated to quickly complete the construction of the high-rise building.

[0029] After assembly, professional waterproofing and surface treatment are performed on the wall joints to improve the waterproof performance of the wallboard 10. In addition, anti-corrosion and rust treatment is performed on the surface of the H-steel frame 20, which will significantly extend the service life of the prefabricated building and ensure its durability in different environments. Overall, the present invention provides a convenient and efficient construction solution by adopting new materials and structural designs, which can meet the multiple requirements of modern buildings for safety, performance and economy.

[0030] More specifically: In an optional embodiment, the waterproofing treatment in S4.6 is specifically as follows: fire retardant paint is applied to the four-frame steel structure, waterproof glue is applied to the joints between the fixed plate angle steel and the steel buckle, rock wool is pressed into the gap between the four frames and the wall panels 10, the joints are smoothed with putty, and then a waterproof coating is sprayed.

[0031] In this embodiment: the surface of the H steel frame 20 is painted with fire retardant paint to enhance its fire resistance. The barrier formed by the fire retardant paint enables the H steel to withstand higher temperatures and slow down the deformation and damage of the material. Waterproof glue is applied to the connection points and bolt connection points to prevent external rainwater from penetrating into the H steel frame 20 through the connection gaps, ensuring the dryness and rust prevention of the frame, which not only enhances the stability of the overall structure, but also effectively avoids potential corrosion problems caused by water intrusion, thereby extending the service life of the H steel frame. At the same time, the use of waterproof glue also helps to keep the inside of the wall dry and prevent the growth of mold and other harmful substances.

[0032] Rock wool is used as a gap filling material, which is consistent with the middle layer material of the wall panel 10. This design not only ensures the consistency of the thermal insulation and noise reduction performance of the wall, but also effectively prevents the problem of excessive difference in wall deformation caused by temperature changes, and prevents the formation of thermal bridges in the gaps, thereby improving the thermal insulation of the building. Temperature fluctuations are often the main cause of cracks in the wall, and the excellent performance of rock wool can just alleviate this effect. At the same time, rock wool itself has certain fire resistance, which is an indispensable factor in the design of prefabricated buildings, improving the overall fire resistance index of the building and providing a safer environment for residents.

[0033] By combining fire prevention measures with waterproofing, the safety performance of building design has been significantly improved. The application of surface waterproof coating treatment further enhances the waterproof performance of prefabricated buildings, enabling the structure to more effectively resist the impact of changes in the external environment. This multiple protection measure not only improves the durability and safety of the building, but also creates a more comfortable and reliable living space for users.

[0034] Overall, the fireproof paint coating and fine waterproof treatment of the H steel frame 20, plus the thermal insulation and fireproof functions of rock wool, can better meet the user's needs in terms of safety, comfort and environmental protection.

[0035] Going further: In an optional embodiment, the surface treatment in S4.7 specifically includes: using a sandpaper tool to grind the surface until it is smooth, and then applying decorative paint.

[0036] In this embodiment: through surface treatment, the outer wall part of the assembled wall body achieves a smooth and beautiful effect, which not only improves the appearance quality of the building, but also provides a good foundation for subsequent decoration.

[0037] On this basis, the use of high-quality decorative paint to paint the wall can present a richer visual effect. The diverse color selection and unique texture design enable the wall to blend harmoniously with the surrounding environment, creating a different atmosphere and style. Decorative paint can not only enhance the ornamental value of the wall, but also has certain functionality. It has good wear resistance, anti-fouling, waterproof and anti-ultraviolet functions, which to a certain extent prolongs the service life of the wall and reduces the subsequent maintenance cost. After being treated with decorative paint, the wall is more durable and can effectively resist the erosion of the external natural environment, so that the prefabricated wall always remains as new, showing a lasting beauty.

[0038] An exterior wall composed of a multi-layer wall panel and a steel structure includes a plurality of wall panels 10 plugged into each other, the wall panel 10 includes an exterior wall layer 11, an intermediate layer 12, and an interior wall layer 13, the exterior wall layer 11 is made of ceramsite and concrete, glass fiber is laid in the exterior wall layer 11, a skeleton composed of fine steel bars is inserted inside, the intermediate layer 12 is a rock wool board, and the interior wall layer 13 is aerated concrete, splicing grooves 14 and clamping platforms 15 are formed on both sides of the wall panel 10, an H-steel frame 20 is provided on the outer side wall of the wall panel 10, the H-steel frame 20 includes an upper beam, a lower beam and a column, and the H-steel frame 20 is fixedly connected by bolts.

[0039] In this embodiment: the present invention adopts an assembled design, fully considering the needs and efficiency of modern building construction, the size of individual structural parts is small, which is convenient for modular transportation and installation, and improves the flexibility and convenience of assembly operations. The wall panel 10 in the present invention is a three-layer structure, which is synthesized by three different lightweight materials to form a sandwich structure of an outer layer of ceramsite concrete-a rock wool middle layer insulation-an inner layer of aerated concrete, which is cast on both sides by the middle layer 12; wherein the outer wall layer 11 of the wall panel 10 adopts a composite material, specifically a concrete structure with glass fiber, ceramsite and fine steel bars. The ceramsite has good fire resistance and loose and porous characteristics, and its light physical properties enable it to effectively reduce the overall weight of the wall panel 10, thereby realizing a lightweight design. The existing outer walls of the walls on the market are mostly common concrete castings, and the overall weight of the outer walls is heavy. In this solution, by adding ceramsite, the outer wall layer 11 is lightweight, which not only improves the convenience of construction compared to the existing concrete walls, but also significantly reduces energy consumption and labor costs during transportation and installation.

[0040] At the same time, the strength of the outer wall layer 11 is significantly improved by adding glass fiber and fine steel bars. These reinforcing materials can effectively improve the stability of the outer wall layer, making it more earthquake-resistant and wind-resistant, thereby ensuring the safety and durability of the building under severe weather conditions, and having better stability than the outer wall cast with ordinary concrete. At the same time, the strength of the outer wall layer 11 can reach the standards of C20 to C45, ensuring that it meets the safety specifications and quality requirements of modern buildings.

[0041] The middle layer 12 of the wall panel 10 is made of rock wool. Existing wall panels mostly use polyurethane or its foamed products as the middle insulation layer, which has poor fireproof performance and is difficult to combine with the outer wall and inner wall of the wall panel 10. The present invention uses the excellent thermal insulation and sound insulation performance of rock wool to further improve the comfort inside the prefabricated building. Using a mold, pouring is carried out on both sides of the rock wool. During pouring, the surface of the rock wool is roughened to fully combine the concrete with the fibers on the surface of the rock wool to improve firmness. The thermal insulation effect of the rock wool makes the indoor environment warmer and more pleasant, and its sound insulation characteristics effectively reduce the interference of external noise, creating a quiet and comfortable living space. In addition, the lightweight characteristics of rock wool further reduce the total weight of the wall panel 10, and its fire resistance is much higher than that of traditional materials.

[0042] The inner wall layer 13 of the wall panel 10 is made of aerated concrete. This material not only has good thermal insulation performance, but also is not easy to crack when processing such as grooving and drilling, which greatly facilitates the subsequent interior decoration work. The inner wall of the existing assembled wall is generally cast in concrete like the outer wall, which feels cold and hard, and is not suitable for direct living. The wall surface needs to be decorated. It is difficult to groove and drill holes during decoration. If the decoration is greatly changed, it is easy to damage other structures of the wall, which has always been a very difficult problem. The present invention uses the high affinity of aerated concrete to make the building wall surface do not need to be excessively decorated, improve the comfort and quality of life of the residents, and also has better thermal insulation performance and lighter weight.

[0043] The wall panel 10 of the present invention is composed of a sandwich structure of the above-mentioned ceramsite concrete outer layer-rock wool middle layer insulation-aerated concrete inner layer. By pouring both sides of the middle layer 12, a complete wall panel 10 is formed, which is overall stable and firm and not easy to delaminate.

[0044] In the actual assembly operation, the splicing groove 14 and the clamping platform 15 of the wall panel 10 are engaged with each other through a simple docking operation, which is simple and efficient. With the assistance of the steel buckle 3 and the fixing angle steel 4, the wall panel 10 can be stably and firmly fixed inside the H steel frame 20 to ensure the safety and stability of the overall structure.

[0045] To further enhance the overall stability and strength, the connection gaps and bolt gaps are treated with waterproof glue, which not only prevents water from penetrating, but also improves the firmness of the overall structure and reduces damage and aging caused by environmental factors. This series of designs and careful selection of materials fully demonstrates the advantages of the invention in terms of functionality, economy and comfort, and provides reliable technical support and new solutions for modern prefabricated buildings.

[0046] Going further: In an optional embodiment, C-shaped steels are provided on the top and bottom of the wall panel 10 , and the wall panel 10 and the C-shaped steels constitute a panel structure and are embedded in the interior of the H-steel frame 20 .

[0047] In this embodiment, by using C-shaped steel, the wall panel 10 can be easily inserted into the C-shaped steel during assembly, thereby forming a larger continuous wall surface. This design not only simplifies the assembly process, but also significantly improves the efficiency of construction. In traditional construction methods, the installation of a single wall panel often requires a long time and cumbersome operations, while the use of C-shaped steel for large-area wall assembly allows multiple wall panels 10 to be quickly connected in one assembly, greatly shortening the operation time and improving construction efficiency.

[0048] C-shaped steel, as the basic structural material for connection and support, further improves the stability of the wall panel 10. This type of steel has excellent bending and shear resistance, can effectively disperse the stress between the wall surface and the foundation, and ensure the firmness and safety of the overall structure. At the same time, the C-shaped steel increases the connection strength between the wall panels 10 during the connection process, forming a tight and stable structure, reducing the risk of displacement and deformation caused by the passage of time or external forces.

[0049] In addition, the application of C-shaped steel also makes the entire wall more resistant to external conditions such as shear force and wind pressure, thereby improving the durability and safety of the building. Through this assembly method, the construction team can more flexibly respond to various construction environments and challenges, ensuring the stability and firmness of the wall panels after installation.

[0050] Going further: In an optional embodiment, prefabricated windows and prefabricated doors penetrating the wall panel 10 are embedded in the surface of the wall panel 10 .

[0051] In this embodiment: this design avoids the need to groove the wall panels 10 at the locations of doors and windows during the construction process, thereby preventing damage to the structure of the wall panels 10, while also improving construction efficiency and simplifying assembly.

[0052] Going further: In an optional embodiment, a plurality of steel buckles 3 are provided between the wall panel 10 and the column. The steel buckles 3 are fixed to the column by bolts. The steel buckles 3 clamp both sides of the wall panel 10 .

[0053] In this embodiment: through this design, the steel buckle 3 is used to limit and fix the wall panel 10, thereby improving the stability of the installation of the wall panel 10, and the operation is simple and quick.

[0054] Going further: In an optional embodiment, a plate fixing angle steel 4 is embedded between the wall panel 10 and the upper beam, and the plate fixing angle steel 4 is arranged at the connection between the two wall panels 10 .

[0055] In this embodiment: through this design, the plate fixing angle steel 4 fixes two adjacent wall panels 10 , further improving the stability of the wall panels 10 .

[0056] Going further: In an optional embodiment, the prefabricated windows and prefabricated doors are fixed to the wall panels 10 by means of screws, and the gaps are filled with waterproof glue.

[0057] In this embodiment: waterproof glue is used to prevent water seepage in the connection gaps, thereby improving the waterproof performance of the prefabricated building and improving the living experience of the residents.

[0058] Going further: In an optional embodiment, hanging holes are provided on both end surfaces of the C-shaped steel.

[0059] In this embodiment, the lifting holes facilitate the lifting of the C-shaped steel and the wall panel 10, thereby achieving a one-time assembly of a larger wall panel 10.

[0060] The overall working principle and use process of the present invention: The present invention adopts H-steel as the frame and load-bearing structure to construct an efficient and stable prefabricated building solution. H-steel not only provides a strong load-bearing capacity, but also its structural form enables the entire building to have good seismic performance. Steel buckles 3 are fixed on both sides of the frame to accurately limit the wall panels 10, which can effectively prevent misalignment or tilt during construction or use. At the same time, the fixed plate angle steel 4 fixed on the upper and lower beams further enhances the stability of the wall panels 10, ensuring that they can maintain a good shape when subjected to external forces or environmental changes.

[0061] The wall panel 10 adopts a three-layer structure design, with the outer layer having high-strength materials, and the middle layer 12 using rock wool with excellent sound insulation and thermal insulation performance. This three-layer structure not only reduces the overall weight of the wall, facilitating transportation and installation, but also ensures excellent thermal insulation and sound insulation, providing residents with a warm and quiet indoor environment. This combination of light weight and high strength enables the wall panel 10 to meet higher functional requirements in modern buildings.

[0062] The wall panel 10 of the present invention is designed as a detachable module with a length of less than 6 meters, which is convenient for manufacturing, transportation and on-site installation. This modular design greatly improves the flexibility and efficiency of construction. In the actual assembly process, the upper and lower sides of the wall panel 10 are clamped and fixed by using C-shaped steel, combined with the installation of the fixing plate angle steel 4, and fixed by using bolts passing through the C-shaped steel to form a larger whole. In this way, during the hoisting stage, a larger area of ​​wall can be effectively assembled at one time, greatly reducing the process and time in the construction.

[0063] During the hoisting process, the wall panel 10 and the C-shaped steel can be calibrated and installed with the help of laser ranging, radar positioning, manipulators, etc., and inserted into the H-steel frame 20 together. The fixed plate angle steel 4 and the H-steel frame 20 are connected by bolts, and the steel buckle 3 and the wall panel 10 are connected at the same time to ensure the firmness of the entire structure. This connection method not only improves the overall stability of the structure, but also simplifies the assembly process, making on-site construction more efficient. When the assembly of a layer of the building is completed, a new H-steel frame 20 can be docked on the top of the H-steel frame 20, and then the above assembly steps are repeated to quickly complete the construction of the high-rise building.

[0064] After assembly, professional waterproofing and surface treatment are performed on the wall joints to improve the waterproof performance of the wallboard 10. In addition, anti-corrosion and rust treatment is performed on the surface of the H-steel frame 20, which will significantly extend the service life of the prefabricated building and ensure its durability in different environments. Overall, the present invention provides a convenient and efficient construction solution by adopting new materials and structural designs, which can meet the multiple requirements of modern buildings for safety, performance and economy; The present invention adopts an assembled design, which fully considers the needs and efficiency of modern construction. The individual structural parts are small in size, which is convenient for modular transportation and installation, and improves the flexibility and convenience of assembly operations. The outer wall layer 11 of the wall panel 10 adopts a composite material, specifically a concrete structure with glass fiber, ceramsite and fine steel bars. The ceramsite has good fire resistance and loose and porous characteristics, and its light physical properties enable it to effectively reduce the overall weight of the wall panel 10, thereby realizing a lightweight design. This lightweight design not only improves the convenience of construction, but also significantly reduces energy consumption and labor costs during transportation and installation.

[0065] By adding glass fiber and fine steel bars, the strength of the outer wall layer 11 is significantly improved. These reinforcement materials can effectively improve the stability of the outer wall layer, making it more earthquake-resistant and wind-resistant, thereby ensuring the safety and durability of the building under severe weather conditions. At the same time, the strength of the outer wall layer 11 can reach the C45 standard, ensuring that it meets the safety standards and quality requirements of modern buildings.

[0066] The middle layer 12 is made of rock wool, which uses the excellent thermal insulation and sound insulation properties of rock wool to further improve the comfort inside the prefabricated building. The thermal insulation effect of rock wool makes the indoor environment warmer and more pleasant, while its sound insulation properties effectively reduce the interference of external noise, creating a quiet and comfortable living space. In addition, the lightweight properties of rock wool further reduce the total weight of the wall panel 10.

[0067] The inner wall layer 13 is made of aerated concrete, which not only has good thermal insulation performance, but also is not easy to crack during processing such as grooving and drilling, which greatly facilitates the subsequent interior decoration work. The high affinity of aerated concrete makes the interior decoration and effect of the building look brand new, and improves the comfort and quality of life of the residents.

[0068] In the actual assembly operation, the splicing groove 14 and the clamping platform 15 of the wall panel 10 are engaged with each other through a simple docking operation, which is simple and efficient. With the assistance of the steel buckle 3 and the fixing angle steel 4, the wall panel 10 can be stably and firmly fixed inside the H steel frame 20 to ensure the safety and stability of the overall structure.

[0069] To further enhance the overall stability and strength, the connection gaps and bolt gaps are treated with waterproof glue, which not only prevents water from penetrating, but also improves the firmness of the overall structure and reduces damage and aging caused by environmental factors. This series of designs and careful selection of materials fully demonstrates the advantages of the invention in terms of functionality, economy and comfort, and provides reliable technical support and new solutions for modern prefabricated buildings.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
