Description

Technical Field

[0001] This utility model relates to the field of composite wall panel technology, and in particular to fiber cement integrated composite wall panel. Background Technology

[0002] Against the backdrop of the rapid development of building industrialization and prefabricated buildings, composite wall panels, due to their integration of functions such as protection, heat insulation, and decoration, are widely used in industrial plants, civil buildings, public facilities, and other scenarios. Performance optimization and construction efficiency improvement have become the core research and development directions of the industry. Currently, composite wall panels on the market have several technical pain points: Firstly, the core load-bearing frame is mostly made of steel or ordinary aluminum alloy. Although steel frames have high strength, their excessive weight increases transportation and hoisting costs and makes them prone to corrosion, affecting their service life. Ordinary aluminum alloy frames often have unreasonable structural designs, making it difficult to balance lightweight and deformation resistance. They are prone to bending and cracking during long-term use and cannot stably support the outer protective panels and internal filling materials. Secondly, the construction efficiency and environmental friendliness are insufficient: the existing wall panel installation mostly relies on on-site welding and drilling for fixing, which requires repeated adjustments to the positioning, resulting in low assembly accuracy and long time consumption, making it difficult to meet the needs of large-scale rapid construction; at the same time, the exterior coating of the wall panels is mostly done on-site after installation, which is greatly affected by weather factors such as rain and humidity, and the coating is prone to unevenness and peeling, requiring frequent touch-up maintenance later, and on-site spraying will generate a large amount of paint waste and dust, increasing the cost of construction waste disposal, which is not in line with the concept of green construction. Third, it is difficult to balance fire resistance and thermal insulation performance with safety: some composite wall panels use polystyrene board and extruded board as filling materials. Although the thermal insulation effect is acceptable, the fire resistance is low, and they are easily combustible and release toxic gases when exposed to fire, posing a serious fire safety hazard. Even when rock wool fireproof materials are used, the heat transfer path is not completely blocked due to the poor filling and poor fit with the frame, resulting in high thermal insulation energy consumption and failing to meet the current building energy conservation standards. Fourth, there are significant defects in the splicing of adjacent wall panels and overall stability: existing splicing structures mostly use simple snap-fit ​​or bolt connections without dedicated stress-distributing components. The splicing points are prone to cracking due to stress concentration, and their wind pressure and seismic resistance are insufficient. At the same time, the sealing of splicing gaps mostly relies on ordinary sealing strips or mortar filling, which has a poor sealing effect and is prone to rainwater leakage and airborne sound transmission problems. This leads to frequent condensation caused by indoor and outdoor temperature differences, and dust easily accumulates in the gaps, increasing the difficulty of cleaning and maintenance. Fifth, the assembly design of the outer protective panels and the frame is unreasonable: the protective panels and the frame of most composite wall panels are arranged flush with each other. There is no overlapping and interlocking structure during installation. They are only fixed by edge bolts. The vertical load cannot be effectively distributed, and individual wall panels are prone to falling off. Moreover, the obvious gaps formed by the flush splicing not only affect the visual integrity of the wall surface, but also easily become channels for moisture and dust to enter, shortening the overall service life of the wall panels. In conclusion, the existing composite wallboards have technical deficiencies in light-weight load bearing, efficient construction, fire prevention and heat insulation, sealing stability, assembly safety and other aspects, which can no longer meet the demand of the construction industry for high-performance, low-energy-consumption and easy-to-construct composite wallboards, and there is an urgent need for a new composite wallboard structure that can comprehensively solve the above problems.

[0005] preferably, a steel keel is arranged between two adjacent aluminum alloy frames, and a sealant layer is coated between two adjacent aluminum alloy frames.

[0006] preferably, the high-density fiber cement boards are arranged in a staggered manner with the aluminum alloy frame preferably, the lower end of the high-density fiber cement board extends out of the lower end of the aluminum alloy frame, and the upper end of the high-density fiber cement board does not completely cover the upper end of the aluminum alloy frame.

[0007] Compared with the prior art, the beneficial effects of the present utility model are: 1. The integrated fiber cement composite wallboard takes the lightweight and high-strength aluminum alloy frame as the main body, which not only bears the overall force support due to material properties, reduces the cost of transportation and hoisting, but also ensures long-term deformation resistance; the hui-shaped guide groove on the frame is precisely matched with the protruding structure of the installation framework to form a directional sliding channel, avoiding installation deviation to improve assembly accuracy, and simplifying the process to reduce manual adjustment time.

[0008] 2. In the integrated fiber cement composite wallboard, the high-density fiber cement boards on both sides of the frame form a rigid-flexible cooperative stress system with the aluminum alloy frame by virtue of the fiber-cement composite structure, which can effectively resist external impact and environmental erosion to prolong the service life; the factory prefabricated coating layer on the outer side of the boards improves the adhesion through substrate pretreatment, which not only avoids the on-site coating being affected by weather, ensures the uniformity and adhesion of the coating to reduce the later paint replenishment and maintenance, but also meets customers' personalized appearance requirements and improves the aesthetic degree of the building.

[0009] 3. The fiber cement integrated composite wall panel has fireproof and heat-insulating rock wool filling the frame. It achieves heat insulation by blocking heat transfer through the interwoven porous structure of fibers. It also contains flame-retardant components that do not release toxic gases when exposed to fire.

In this fiber cement integrated composite wall panel, the steel keel between adjacent frames is rigidly connected to the frame on both sides by bolts, forming a cooperative stress-bearing node to disperse splicing stress, improve the overall wind pressure resistance and seismic performance to avoid cracking at the splicing. The sealant layer applied to the gaps forms an elastic seal after curing, blocking the flow of air and moisture to achieve good sound insulation and waterproofing, reducing outdoor rainwater leakage and condensation problems caused by indoor and outdoor temperature differences.

[0017] Please refer to Figure 1-3 , the present utility model provides a technical solution: an integrated fiber cement composite wallboard, comprising an aluminum alloy frame 1, wherein a guide groove 2 with a vertical cross-section in a shape of a Chinese character 'hui' is provided on the aluminum alloy frame 1; high-density fiber cement boards 7 are respectively fixedly connected to two sides of the aluminum alloy frame 1, and a coating layer 3 is coated on a side of the high-density fiber cement board 7 away from the aluminum alloy frame 1; fireproof and thermal insulation rock wool 4 is filled inside the aluminum alloy frame 1; the composite wallboard can be independently inserted into the framework through the provided guide groove 2, meanwhile the coating layer 3 can be coated according to customers' requirements without re-coating after installation, thereby improving construction efficiency and reducing construction waste generated in subsequent coating; a section steel keel 5 is arranged between two adjacent aluminum alloy frames 1, and a sealant layer 6 is coated between two adjacent aluminum alloy frames 1; wherein the high-density fiber cement boards 7 are arranged in a staggered manner with respect to the aluminum alloy frame 1, that is, the lower end of the high-density fiber cement board 7 extends out of the lower end of the aluminum alloy frame 1, and the upper end of the high-density fiber cement board 7 does not completely cover the upper end of the aluminum alloy frame 1; through the staggered arrangement, the composite wallboard is installed in a staggered manner during installation, thereby improving stability and firmness.

[0018] Working principle: the lightweight and high-strength aluminum alloy frame 1 is used as the main body, which bears the overall force support of the utility model due to its material properties, reduces the cost of transportation and hoisting, and ensures long-term deformation resistance; the square-shaped guide groove 2 on the frame is precisely matched with the protruding structure of the installation framework to form a directional sliding channel, which avoids installation deviation to improve assembly accuracy, simplifies the process and reduces manual adjustment time; The high-density fiber cement board 7 on both sides of the frame, with its fiber and cement composite structure, forms a rigid-flexible synergistic force system with the aluminum alloy frame 1, which effectively resists external impact and environmental erosion to extend service life. The pre-fabricated coating layer on its outer side is pre-treated with the substrate to improve adhesion, which not only avoids the weather affecting on-site painting and ensures the uniformity and adhesion of the coating to reduce the need for later touch-up maintenance, but also meets the personalized appearance requirements of customers and enhances the aesthetics of the building. The fireproof and heat-insulating rock wool 4 filling the frame relies on the interwoven porous structure of fibers to block heat transfer and achieve heat insulation. It also contains flame-retardant components that do not release toxic gases when exposed to fire. This not only reduces the energy consumption of building air conditioning and heating to meet energy-saving standards, but also improves the fire safety level, buys time for people to evacuate in the event of a fire and reduces secondary injuries. In terms of installation efficiency, the plug-in design of the guide groove 2 does not require on-site welding and drilling. It can be quickly positioned by matching the groove. The prefabricated coating layer 3 skips the on-site base treatment and coating process to achieve the finished wall surface, which shortens the installation time of a single wall panel to adapt to large-scale rapid construction. At the same time, it reduces on-site dust and paint waste and other construction waste, reduces environmental protection treatment costs and avoids pollution of other decoration components. The steel keel 5 between adjacent frames is rigidly connected to the two side frames by bolts, forming a cooperative stress-bearing node to disperse splicing stress, improve the overall wind pressure resistance and seismic performance to avoid cracking at the splicing point. The sealant layer 6 applied to the gap forms an elastic seal after curing, blocking the flow of air and moisture to achieve good sound insulation and waterproofing, reducing outdoor rainwater leakage and condensation problems caused by indoor and outdoor temperature differences. The staggered arrangement of the high-density fiber cement board 7 and the aluminum alloy frame 1 allows the lower end of the upper wall panel frame and the upper end of the cement board extending from the lower wall panel to form an interlocking structure during installation. Combined with bolts for auxiliary fixing, a dual stability system of upper interlocking and bolt reinforcement is formed. This system not only disperses the vertical load of the wall panel to improve shear resistance and avoids the risk of single wall panel falling off, but also covers the gaps in the frame splicing, reducing dust accumulation and rainwater infiltration. At the same time, it enhances the visual integrity of the wall surface to weaken the splicing marks.

[0019] Structural Description: Aluminum alloy frame 1: As the core load-bearing structure of the wall panel, it undertakes the overall load-bearing function. Its material has both lightweight and high strength characteristics, which reduces the cost and operation difficulty in the transportation and hoisting of the wall panel on the one hand, and ensures that it is not easily deformed during long-term use on the other hand. The two sides of the frame are used to fix and connect high-density fiber cement board 7, and the interior is reserved to fill the space to accommodate fireproof and heat-insulating rock wool 4, providing basic frame support for the protection and heat insulation performance of the wall panel. It is the core carrier for integrating various functional components. Guide groove 2: provided on the surface of the aluminum alloy frame 1, with a vertical cross-section in a shape of a square ring. The structure is precisely adapted to the protruding structure of the mounting framework to form a directional sliding channel, so that the composite wallboard can be independently inserted into the framework to complete assembly; on-site welding or drilling for fixing is not required, which can not only avoid position deviation during installation and improve assembly accuracy, but also simplify the installation process and reduce manual adjustment time, providing conditions for large-scale rapid construction. Coating layer 3: coated on the side of the high-density fiber cement board 7 away from the aluminum alloy frame 1, and is formed by a factory prefabricated spraying process. The coating scheme can be customized according to customers' individual requirements, and the prefabricated process can improve the adhesion of the coating and ensure the uniformity of the coating through base material pretreatment; no secondary coating is required after installation, which not only avoids the influence of weather factors such as rain and humidity on on-site coating, reduces later paint repair and maintenance work, but also reduces the generation of construction waste such as on-site paint waste and dust, giving consideration to both appearance aesthetics and construction environmental protection.

[0020] Fireproof and thermal insulation rock wool 4: filled in the inner space of the aluminum alloy frame 1. The material forms a porous structure through fiber interweaving, and the still air in the pores can block heat transfer, achieve high-efficiency thermal insulation effect, reduce the energy consumption of building air conditioning and heating, and comply with energy-saving standards; at the same time, the rock wool contains flame-retardant components, which can inhibit the spread of combustion and do not release toxic gas in case of fire, effectively improving the fire safety level of buildings, winning time for personnel evacuation in fire scenarios and reducing the risk of secondary injuries. Section steel keel 5: arranged between two adjacent aluminum alloy frames 1, and forms a rigid connection with the frames on both sides through bolts. This structure constructs a stress node with cooperative bearing of frames and keels, which can disperse and transmit the concentrated stress at the joint of adjacent wallboards, enhance the overall wind resistance and seismic performance of the wallboards, avoid cracking at the joint parts caused by uneven stress, and further improve the structural stability of the wallboard system. Sealant layer 6: coated in the gap between two adjacent aluminum alloy frames 1, and forms an elastic sealing body after the colloid is cured. Its core function is to fill the gap between frames and block the circulation path of air and moisture: on the one hand, it achieves a good sound insulation effect and reduces the interference of outdoor noise through air-borne sound transmission in the gap; on the other hand, it effectively prevents outdoor rain water from leaking into the room, and at the same time avoids the problem of condensation in the gap caused by the temperature difference between indoor and outdoor, improving the waterproof sealing performance and use comfort of the wallboard. High-density fiber cement board 7: Installed on both sides of the aluminum alloy frame 1 via a fixed connection, with a staggered arrangement. Specifically, the lower end of the cement board extends beyond the lower end of the aluminum alloy frame 1, while the upper end does not completely cover the upper end of the aluminum alloy frame 1. Its fiber and cement composite structure forms a rigid-flexible synergistic force-bearing system with the aluminum alloy frame 1, resisting external impacts and environmental erosion, and extending the service life of the wall panel. The staggered design creates an interlocking structure during wall panel installation. With the assistance of bolts for fixation, it can not only distribute vertical loads and improve shear resistance, avoiding the risk of single wall panel detachment, but also cover the frame splicing gaps, reduce dust accumulation and rainwater infiltration, and enhance the visual integrity of the wall surface.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
