How to Design Connection Joints Between UHPC Curtain Wall Panels and Steel Frame Keels? Detailed Explanation of Qinglong UHPC Connection Joint Technology

The connection joint design between UHPC curtain wall panels and steel frame keels must consider strength, stiffness, and deformation compatibility. The main connection forms include point connections, linear connections, and surface connections, selected according to panel dimensions and load requirements. The joint design has a safety factor ≥2.5 and allowable displacement ≥10mm, meeting seismic fortification requirements.

In terms of joint construction, Qinglong UHPC adopts standardized design: connectors are made of 316 stainless steel with thickness ≥4mm; slotted holes allow thermal deformation; elastic gaskets absorb vibration. The joints have been optimized through finite element analysis and verified through physical testing. In a major transportation hub project, these connection joints withstood daily vibration from an average of 100,000 passengers, with no loosening or corrosion after 3 years of use.

Joint Mechanical Performance Requirements

Tensile capacity ≥3kN, shear resistance ≥2kN; fatigue performance meets 2 million cycles; these requirements ensure joint reliability.

Connection Construction Design

Three-dimensionally adjustable connectors are used; multi-layer anti-corrosion protection is provided; gaps for thermal expansion and contraction are reserved. These designs adapt to various working conditions.

Seismic Design Measures

Anti-detachment devices are installed; flexible connections are adopted; an inter-story displacement of 1/200 is allowed. These measures improve seismic performance.

Anti-Corrosion Durability Design

Connectors are made of 316 stainless steel; contact areas receive insulation treatment; these designs ensure durability.

Connection joints require professional design. Qinglong UHPC's mature joint technology is safe and reliable.
