Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and particularly to a prefabricated exterior wall. Background Art

[0002] In the construction industry, the construction technology of the exterior wall system has undergone a transformation from traditional on-site casting to prefabricated construction. Traditional methods such as on-site casting and bricklaying, although able to meet the basic construction needs in the early stage, have long construction periods, high labor costs, many safety hazards, and do not meet the increasingly strict green environmental protection requirements. In recent years, with the development of industrialization and informatization technologies, prefabricated buildings have gradually become the mainstream trend. Especially in the construction of new residential buildings, commercial complexes, and public facilities, etc., the prefabricated exterior wall system has received extensive attention due to its high efficiency, safety, and environmental protection characteristics.

[0003] In order to improve construction efficiency and reduce costs, various prefabricated exterior wall systems have emerged in the market. Common solutions include: on-site assembly of semi-prefabricated components, which reduces a certain proportion of on-site wet work through the use of some prefabricated components, but still requires a large amount of manual participation and has limited construction efficiency; direct hoisting of fully prefabricated components, which greatly speeds up the construction progress by completing all prefabrication work in the factory, but the functional integration of the prefabricated components is not high, resulting in a large amount of subsequent secondary processing and increasing the overall project cost.

[0004] Although the above solutions have alleviated many problems of traditional exterior wall construction to a certain extent, their common defects are single function, low integration, and insufficient intelligence. For example, on-site assembly of semi-prefabricated components reduces wet work, but the construction efficiency is still low; direct hoisting of fully prefabricated components speeds up the construction progress, but the cost of subsequent secondary processing is relatively high.

Detailed implementation manners

[0029] The following further elaborates on this application in detail with reference to all the attached drawings.

[0030] The embodiment of this application discloses a prefabricated exterior wall.

[0031] Referring to Figure 1 , a prefabricated exterior wall includes an integrated prefabricated module 1, an intelligent environment monitoring and regulating system, a corrugated structure 3, and a decorative grille 4.

[0032] Referring to Figure 1 and Figure 2 , the integrated prefabricated module 1 sequentially includes a decorative layer 11, a thermal insulation layer 12, a waterproof layer 13, and a structural layer 14 from outside to inside.

[0033] Referring to Figure 1 , the decorative layer 11 is located on the outermost side. The decorative layer 11 is made of high-strength lightweight concrete, which has good weather resistance and aesthetics. This material can not only withstand the influence of the external environment, such as wind, rain, sun exposure, etc., but also provide a rich selection of colors and textures to meet the requirements of different architectural styles. In addition, the surface of the decorative layer 11 can be subjected to various treatments, such as spraying, carving, etc., to increase its artistic and personalized nature. The thickness of the decorative layer 11 is usually between 10 - 20 mm, and the specific thickness can be adjusted according to the actual engineering requirements.

[0034] Referring to Figure 1, the thermal insulation layer 12 is adjacent to the inner side of the decorative layer 11. The polyurethane foam with a high closed-cell rate is selected for the thermal insulation layer 12, which has excellent thermal insulation performance. Polyurethane foam is a high-performance thermal insulation material with a closed-cell rate of over 95%, which can effectively block heat transfer and reduce energy loss. In addition, polyurethane foam also has good waterproof performance and can maintain a stable thermal insulation effect in a humid environment. The thickness of the thermal insulation layer 12 is usually between 50 - 100 mm, and the specific thickness can be adjusted according to the climate conditions of the building location.

[0035] Refer to Figure 1 , the waterproof layer 13 is located on the inner side of the thermal insulation layer 12. The high-elastic modified asphalt waterproof coating is selected for the waterproof layer 13, which has good waterproof performance. Modified asphalt waterproof coating is a commonly used waterproof material with good elasticity, which can adapt to the minor deformation of the base layer and prevent water penetration. The specific coating thickness of the waterproof layer 13 should be adjusted according to the actual project requirements. The construction methods of the waterproof layer 13 usually include spraying, brushing or rolling to ensure the uniformity and integrity of the waterproof layer 13.

[0036] Refer to Figure 1 , the structural layer 14 is located on the innermost side. High-strength lightweight concrete is selected for the structural layer 14 to reduce the weight while ensuring the structural strength. This material has a relatively high compressive strength and a low density, which can reduce the self-weight of the wall and thus reduce the foundation load on the premise of ensuring structural safety. The thickness of the structural layer 14 is usually between 100 - 150 mm, and the specific thickness should be adjusted according to the height and structural requirements of the building.

[0037] The decorative layer 11 and the thermal insulation layer 12 can be connected by adhesives or mechanical fixing methods. The thermal insulation layer 12 and the waterproof layer 13 can also be connected by adhesives or mechanical fixing methods. The waterproof layer 13 and the structural layer 14 are connected by pouring or mechanical fixing methods. This multi-layer structural design not only ensures the various functions of the exterior wall but also improves the construction efficiency and safety. For example, high-performance construction adhesives can be selected as adhesives to ensure the bonding strength between layers; high-strength bolts or anchor bolts can be selected for mechanical fixing to ensure the stable connection between layers.

[0038] Refer to Figure 1 and Figure 2, the structural layer 14 is circumferentially provided with grooves 141. Four groups of steel bar groups 142 are fixedly arranged in the grooves 141. The steel bar groups 142 are respectively located at the four sides of the structural layer 14. The upper steel bar group 142 and the lower steel bar group 142 are staggered, and the left steel bar group 142 and the right steel bar group 142 are staggered. Each group of steel bar groups 142 includes connecting bars 1421 and several inserted bars 1422. The connecting bars 1421 and the inserted bars 1422 are fixed together by wire binding or welding. The connecting bars 1421 and the inserted bars 1422 are perpendicularly fixed. The inserted bars 1422 extend out of the groove 141 along the depth direction perpendicular to the groove 141, and the length of the inserted bars 1422 is not greater than the depth of the groove 141. When adjacent integrated prefabricated modules 1 are assembled on site, the adjacent grooves 141 are fitted together to form a channel. The steel bar groups 142 in the adjacent grooves 141 are staggered, and the inserted bars 1422 extend into the grooves 141 of the adjacent structural layer 14. Concrete is poured into the channel to fix the adjacent integrated prefabricated modules 1 together. This design not only enhances the rigidity and stability of the structural layer 14, but also improves the seismic performance of the wall. The material of the connecting bars 1421 is high-strength steel bars, which have good tensile and compressive properties; the material of the inserted bars 1422 is stainless steel with good corrosion resistance to ensure that there will be no rust and aging phenomena during long-term use. The connecting bars 1421 and the inserted bars 1422 are connected by welding or mechanical fixing methods to ensure firm connection and at the same time have a certain supporting effect on the wall, making the whole wall more solid. The length of the inserted bars 1422 is limited within the range not exceeding the depth of two grooves 141 to ensure the firmness of the assembly connection of adjacent integrated prefabricated modules 1.

[0039] Refer to Figure 2 , the intelligent environment monitoring and regulating system includes a micro sensor network 2 and an intelligent control system. The micro sensor network 2 includes a pressure sensor 21, a humidity sensor 22 and a temperature sensor 23. The pressure sensor 21 is located in the structural layer 14 and is used to monitor the stress condition of the wall; the humidity sensor 22 is located in the waterproof layer 13 and is used to monitor the humidity change inside the wall; the temperature sensor 23 is located in the insulation layer 12 and is used to monitor the temperature change inside the wall. These sensors are connected to the intelligent control system through a wireless communication module. The intelligent control system automatically adjusts the size of the ventilation openings or other parameters inside the wall according to the data collected by the sensors to achieve the purpose of optimizing the indoor environment. For example, when the indoor temperature is too high, the intelligent control system will automatically open the ventilation openings to lower the indoor temperature; when the indoor humidity is too high, the intelligent control system will automatically close the ventilation openings to prevent moisture from entering the room. This intelligent design not only improves the living comfort, but also facilitates the later maintenance.

[0040] Refer to Figure 1 and Figure 3, the corrugated structure 3 includes V-shaped corrugations 31, and reinforcing ribs 32 are fixedly arranged at both the bottom and the top of the V-shaped corrugations 31. The V-shaped corrugations 31 are made of steel with good corrosion resistance and weather resistance, such as galvanized steel sheets or stainless steel sheets. The V-shaped corrugations 31 not only enhance the rigidity and stability of the wall, but also fill the cavities formed by the V-shaped corrugations 31 with high-efficiency thermal insulation materials, such as polyurethane foam, to further improve the thermal insulation performance of the wall. The setting of the reinforcing ribs 32 improves the compressive and bending resistance of the V-shaped corrugations 31, ensuring the long-term stability and reliability of the wall. The material of the V-shaped corrugations 31 can be selected as steel with good corrosion resistance and weather resistance to ensure that there will be no rust and aging phenomena during long-term use.

[0041] Refer to Figure 1 , the decorative grille 4 is located on the side of the decorative layer 11 away from the thermal insulation layer 12. The decorative grille 4 is composed of a number of rectangular frames 41, and the quantity is determined according to the wall area. The material of the decorative grille 4 is selected as wear-resistant and weather-resistant PVC material, which has good weather resistance and aesthetics. The decorative grille 4 is fixedly connected to the decorative layer 11 by snap fasteners or bolts to ensure firm connection, and at the same time has a certain supporting effect on the wall, making the whole wall more solid. The design of the decorative grille 4 not only beautifies the building appearance, but also provides additional protection.

[0042] An anti-ultraviolet coating is provided on the outer surface of each rectangular frame 41. The anti-ultraviolet coating can be selected from high-performance materials such as silicone resin or acrylic resin, or other materials with excellent anti-ultraviolet ability such as fluorocarbon resin. The anti-ultraviolet coating can not only prevent the erosion of ultraviolet rays on the wall materials, extend the service life of the exterior wall, but also improve the aesthetics of the wall, making the building appearance more durable and beautiful. The thickness of the anti-ultraviolet coating is generally 0.1 - 0.3 mm and can be adjusted according to actual needs.

[0043] Refer to Figure 1 , a number of plant planting boxes 6 are fixedly arranged on the decorative grille 4, and each plant planting box 6 is fixedly connected to a rectangular frame 41. Various greening plants, such as Boston ivy and ivy, can be planted in the plant planting boxes 6, which not only beautify the building appearance, but also provide ecological benefits. The material of the plant planting boxes 6 is selected as plastic or metal materials with strong weather resistance, which have good corrosion resistance and weather resistance. The plant planting boxes 6 are fixedly connected to the decorative grille 4 by snap fasteners or bolts to ensure firm connection, and at the same time have a certain supporting effect on the wall, making the whole wall more solid. The design of the plant planting boxes 6 not only adds a natural atmosphere to the building, but also provides additional air purification and cooling effects, improving the living comfort.

[0044] Refer to Figure 1, on the side of the decorative layer 11 close to the decorative grille 4, there is a solar photovoltaic panel 5, and the solar photovoltaic panel 5 is located within the rectangular frame 41. The solar photovoltaic panel 5 can utilize solar energy to generate electricity, reducing the building's energy consumption. At the same time, it can also add a modern sense visually. The solar photovoltaic panel 5 is connected to the intelligent environment monitoring and regulation system, and the generated electric energy is stored in the battery pack through the intelligent control system for use inside the building. This method not only reduces the building's energy consumption but also provides an additional power source for the building, achieving energy self-sufficiency. The material of the solar photovoltaic panel 5 is selected as a single-crystalline silicon or thin-film solar cell with a high conversion efficiency, having good photoelectric conversion efficiency and weather resistance. The solar photovoltaic panel 5 is connected to the decorative layer 11 by means of an adhesive or mechanical fixation, ensuring a firm connection.
