What Are the Requirements for Hanger Spacing and Load-Bearing Capacity When Installing UHPC Curtain Wall Panels? Qinglong UHPC Curtain Wall Hanging System Technical Specifications

The design of hanger spacing and load-bearing capacity for UHPC curtain wall panels must follow strict mechanical calculation principles. According to engineering practice, hanger spacing is generally controlled within the 600-900mm range, and the design load-bearing capacity of a single hanger should not be lower than 3kN, with a safety factor of 2.5. This design ensures the safety performance of the curtain wall system under external forces such as wind loads and seismic action.

In specific designs, Qinglong UHPC uses finite element analysis for optimized calculations: for standard panels (1.2m×3m), 4 hanging points are set at 800mm spacing; for large panels (1.5m×4m), this increases to 6 hanging points at 750mm spacing. Hangers are made of 316 stainless steel; tensile testing shows a failure load of ≥7.5kN, far exceeding design requirements. In a super high-rise project, this hanger system withstood a Force 12 typhoon with a displacement of only 2.3mm, fully meeting code requirements.

Hanger Spacing Design Standards

Standard panels (≤12㎡): hanger spacing 800-900mm; large panels (>12㎡): reduced to 600-750mm; distance from panel edge to the first hanger ≤300mm. These spacings ensure uniform load distribution.

Load-Bearing Capacity Calculation Requirements

In areas with a basic wind pressure of 0.5kPa, single hanger capacity ≥2.5kN; in areas with a basic wind pressure of 0.8kPa, this is increased to ≥3.5kN; seismic fortification areas must consider seismic action combinations. These calculations ensure safety.

Hanger Material and Construction

316 stainless steel is used with thickness ≥4mm; connecting tooth length ≥15mm and tooth depth ≥1mm; a slotted hole design allows ±5mm adjustment. These constructions ensure reliability.

Safety Factor Control

Strength safety factor ≥2.5; fatigue safety factor ≥4; durability considers a 50-year service life. These controls provide sufficient margin.
