Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, specifically to a prefabricated cement-based polymer-ALC large panel composite wall. Background Technology

[0002] ALC stands for Autoclaved Lightweight Concrete, a type of high-performance autoclaved aerated concrete. ALC panels are porous concrete slabs (containing treated steel reinforcement) made primarily from fly ash (or silica sand), cement, and lime, cured under high-pressure steam. ALC panels can be used as wall materials or roofing panels, making them a high-performance new building material. ALC panels are lightweight, heat-insulating, fire-resistant, sound-insulating, environmentally friendly, earthquake-resistant, high-strength, easy to construct, economical, and recyclable, leading to their widespread use in modern architecture. However, due to their porous structure, their waterproof and moisture-proof performance is relatively poor, currently limiting their use to interior walls and limiting their application to exterior walls. ALC panels are loose and lightweight, but relatively brittle. If the width is too large, they are prone to cracking or breakage due to bending or collision during transportation and hoisting. When used as interior wall materials, ALC panels need to withstand seismic forces, and excessive width increases the stress area of ​​a single panel, which may lead to local stress concentration and reduce overall seismic resistance. Therefore, ALC panels are currently mostly processed into strips that are 6 meters or 3 meters high and 0.6-1.6 meters wide. However, this results in more cast-in-place connection nodes during on-site construction, which presents a problem of not being able to balance construction efficiency and wall performance for some cases requiring large-area interior walls. Utility Model Content

[0003] The present invention aims to provide a prefabricated cement-based polymer-ALC large panel composite wall to meet the needs of prefabricated construction of large-area ALC interior walls.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated cement-based polymer-ALC large panel composite wall, comprising an ALC large panel and a cement-based polymer layer. The ALC large panel is a panel with a length ≥3m, a width ≥2m, and a thickness ≥0.1m. The cement-based polymer layer is a layered cement-based polymer that fully covers the surface of the ALC large panel, and the thickness of the cement-based polymer layer is 2mm-5mm.

[0005] Preferably, as an improvement, the cement-based polymer layer is provided on both sides of the ALC slab.

[0006] Preferably, as an improvement, the surface of the ALC large board is provided with several interlocking structures, which are one or more of the following: straight holes, conical holes, irregular holes, rectangular grooves, dovetail grooves, T-grooves, toothed grooves, and protrusions.

[0007] Preferably, as an improvement, the ALC large board is a board with a length of 3m, a width of 2m-3m, and a thickness of 0.1m-0.25m.

[0008] Preferably, as an improvement, the ALC large board is a board with a length of 6m, a width of 2m-3m, and a thickness of 0.1m-0.25m.

[0009] This solution combines cement-based polymers with ALC (autoclaved aerated concrete) panels to form a prefabricated composite wall, integrating the advantages of both and exhibiting the following characteristics and benefits: 1. Enhanced mechanical properties: Cement-based polymers can significantly improve the mechanical properties of ALC panels, such as compressive strength, flexural strength and durability, making composite wall panels more suitable for high-rise buildings, large-span structures and resistance to natural disasters.

[0010] 2. Improved weather resistance: Cement-based polymer modification can enhance the resistance of ALC panels to external environmental erosion (such as wind and rain, temperature changes, humidity fluctuations, etc.), and extend the service life of the exterior wall panels.

[0011] 3. Improve waterproof and moisture-proof performance: The addition of cement-based polymers can improve the density and water repellency of ALC boards, reduce water penetration, thereby improving the waterproof and moisture-proof performance of building exterior walls and effectively avoiding problems such as mold growth and freeze-thaw cycles.

[0012] 4. Optimize thermal insulation performance: ALC boards themselves have good thermal insulation performance. With the modification of cement-based polymers, the thermal performance of the wall can be further optimized, reducing building energy consumption.

[0013] 5. Enhanced connection performance: Cement-based polymers can improve the connection performance of ALC panels with other building components, which is beneficial for prefabricated connection and anchoring, and improves construction efficiency and safety.

[0014] 6. Simplified construction process: Using cement-based polymer modified ALC boards can improve their adaptability and simplify the assembly and construction process, such as reducing on-site plastering and finishing processes, thereby improving construction speed and quality consistency.

[0015] 7. Environmental protection and sustainable development: ALC board itself is a green building material, and it can still maintain this characteristic after being modified with cement-based polymers, reducing environmental pollution and meeting the requirements of sustainable development in modern buildings.

[0016] 8. Increased decorative diversity: Cement-based polymer materials can achieve rich surface textures and color effects, enabling prefabricated exterior wall panels to meet basic performance requirements while also possessing good decorative properties.

[0017] In summary, prefabricated building wall panels formed by combining cement-based polymers and ALC boards combine multiple advantages such as high performance, high durability, easy construction, environmental protection, and energy saving, and represent an important development direction for modern prefabricated building wall panel materials.

[0018] Based on the above advantages, this application designs a dedicated large-panel composite wall, available in lengths of 3 meters and 6 meters, to accommodate single-story or double-story buildings. The ALC large panels are fully covered with cement-based polymer, which significantly improves their mechanical properties while maintaining their lightweight characteristics. This ensures the composite wall has sufficient load-bearing capacity to withstand building weight, live loads (people, furniture, equipment, etc.), wind loads, and seismic loads, preventing excessive deformation or damage under normal use. The cement-based polymer also significantly improves the flexural strength of the ALC large panels, providing sufficient lateral displacement resistance and energy dissipation mechanisms to meet the seismic fortification intensity requirements of the region, resisting the impact and repeated loads of earthquakes. This allows the ALC large panels to be processed to a width of 2-3 meters while maintaining good structural performance and resistance to cracking and damage. During construction, a single panel or 2-3 panels of this composite wall can be used per wall, significantly reducing connection points and balancing construction efficiency with wall performance in prefabricated building construction.

[0019] Composite walls, through a large-area cement-based polymer coating, enhance the resistance of ALC panels to external environmental erosion (such as wind, rain, temperature changes, and humidity fluctuations), enabling them to withstand the long-term effects of natural and man-made factors such as atmospheric erosion, freeze-thaw cycles, salt damage, and fire. The structure primarily uses ALC panels, with the cement-based polymer only fixed to the surface, resulting in low material and construction costs and ensuring optimal cost-effectiveness throughout the structure's lifespan.
