The system’s strength and reliability are derived from its meticulously engineered components and connections:

Primary Structural Frame:

Material: High-strength aluminum alloy.  Key Member: The main load-bearing elements are I-beams with a flange width of 300mm, a web thickness of 11mm, and a flange thickness of 15mm. This profile offers an optimal strength-to-weight ratio, capable of handling significant loads with minimal material use.

High-Strength Connection System:

Fastener: Stainless Steel Grooved Rivets. These are high-performance blind rivets (similar to Huck or Cherry-type fasteners) that provide a vibration-resistant, permanent, and high-clamp-force connection. Connector Node: Thick Aluminum Alloy Disc. These discs act as critical gusset plates or nodal connection points within the dome’s geodesic or grid framework. The 6061-T6 alloy is precipitation-hardened, providing exceptional tensile strength, fatigue resistance, and weldability, making it ideal for highly stressed structural joints.

Daylighting Feature:

Skylight Cover: FRP (Fiber Reinforced Polymer) Sheets. These translucent or transparent panels are made of glass fibers embedded in a polymer resin matrix. They are lightweight, impact-resistant, and provide excellent diffuse natural light transmission. The FRP cover is seamlessly integrated into the aluminum grid, offering weatherproofing, UV resistance, and thermal insulation properties.

Key Advantages:

Lightweight & High Strength: The aluminum alloy structure combined with the FRP skylight offers a much lighter solution than traditional steel and glass, reducing foundation loads and construction costs.

Corrosion Resistance: Both the aluminum structure and stainless steel fasteners provide outstanding long-term resistance to corrosion, minimizing maintenance needs.

Efficient Construction: The use of prefabricated components (I-beams, nodal discs) and mechanical fasteners (grooved rivets) allows for rapid, precise, and dry on-site assembly, shortening project timelines.

Optimal Daylighting: The FRP skylight provides even, glare-free natural illumination, reducing daytime lighting energy consumption.

Aesthetic & Functional Design: The dome shape is architecturally striking, allows for column-free large spaces, and efficiently sheds snow and rain.

Durability: The system is designed for long service life with robust materials and connections resistant to fatigue and environmental stress.

Applications:

Ideal for sports complexes, swimming pool enclosures, shopping malls, transportation hubs, warehouses requiring daylight, and any facility where a wide-span, weatherproof, and naturally lit environment is desired.

In summary, this Aluminum Alloy Dome Roof with FRP Skylight represents a modern, efficient, and sustainable structural solution, where the specific use of the I-beam, Stainless Steel Grooved Rivets, and 6061-T6 Aluminum Alloy Discs ensures a superior, reliable, and long-lasting building envelope system.
