Customization Plan for Prefabricated Arch Roof Houses

The customization plan for prefabricated arch roof houses requires comprehensive planning from five dimensions: design, materials, structural systems, construction installation, and supporting facilities, as detailed below:

I. Design Phase: Balancing Personalization and Structural Safety
Determine the span, curvature, and material strength based on the building's purpose (such as warehousing, sports venues, or agricultural greenhouses), and conduct load analysis using professional software (e.g., SAP2000 or ETABS). For example, industrial plants with a span of 20 meters typically adopt an arc design with a radius of 15-20 meters to distribute the roof's self-weight and snow loads. Design details should be adjusted according to the usage scenario: industrial plants need to reserve positions for skylights or vents; sports venues must ensure unobstructed views for the audience; agricultural greenhouses should optimize light angles and provide 3D model diagrams to ensure seamless integration with the main building structure. Arch roofs support single-curvature, double-curvature, or complex combination designs to meet different scenario requirements.

II. Material Selection: Balancing Performance and Cost
Main materials should be customized according to the scenario: color-coated steel sheets (thickness 0.5-1.2mm) are cost-effective and corrosion-resistant, suitable for industrial scenarios; aluminum alloys (strength ≥300MPa) are lightweight and have a long lifespan, commonly used in high-end venues; PVC membranes (light transmittance 80%-90%) are suitable for agricultural greenhouses, enhancing plant photosynthesis efficiency; steel/concrete combinations can increase load-bearing capacity but have a longer construction period. Auxiliary materials should include high-strength bolts (compliant with GB/T 3098.1 standards), weather-resistant silicone sealants, and waterproof membranes to ensure connection node strength and IP65-level waterproof performance.

III. Customization of Structural Systems: Adapting to Original Building Conditions
In scenarios involving the renovation of existing structures, directly welding support plates to embedded parts is suitable for thick concrete edges; installing H-beam systems with gutter embedded parts is suitable for scenarios requiring horizontal load-bearing expansion; steel corbels require special attention to connection stability verification; concrete corbels + H-beam combinations require strict control over concrete curing quality. For new projects, independent foundations or pile foundations can be selected based on needs, with foundation depth adjusted according to the frost line thickness (e.g., in northern regions, it should extend 0.5 meters below the frost line).

IV. Construction Installation: Step-by-Step Implementation and Quality Control
Factories should conduct 1:1 module pre-assembly to check if the arch curvature meets design requirements. During lifting, use truck cranes or tower cranes for sectional lifting, with each section's weight controlled within 80% of the crane's rated load. High-strength bolts should be used at connections, with torque reaching at least 90% of the design value. After construction, conduct a load test simulating 1.5 times the design load for 24 hours to observe structural deformation and check if the drainage system is unobstructed.

V. Customization of Supporting Facilities: Combining Functionality and Aesthetics
Customize supporting facilities according to the building's purpose: lighting systems can optimize indoor illumination through skylights or light-transmitting membranes; ventilation equipment can reserve vents or install mechanical ventilation devices in conjunction with the arch structure; drainage systems should be designed with appropriate slopes to avoid water accumulation; energy-saving designs can leverage the arch structure to reduce energy consumption, such as using PVC membranes to enhance the insulation performance of agricultural greenhouses.
