Connection Methods Between UHPC Decorative Components and the Main Structure and Key Design Points Analysis

The beauty of architecture begins with connection. In the field of contemporary architectural decoration, UHPC (Ultra-High Performance Concrete) has become the finishing touch of landmark buildings thanks to its outstanding mechanical properties and expressive form. The connection technology between UHPC decorative components and the main structure is the core factor determining a building's safety and artistic quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical strength to provide designers and owners with integrated solutions from detailed design to construction and maintenance, making every connection a dual guarantee of quality and aesthetics.

I. UHPC Decorative Component Connection Methods: Three Systems Building the Cornerstone of Safety

Connecting UHPC decorative components requires balancing structural safety, construction convenience, and long-term durability. Mainstream connection methods fall into three categories: mechanical connection, chemical connection, and combined connection. Mechanical connection achieves physical fixing through metal embedded parts, bolts, and the like, and is suitable for exterior wall cladding panels and irregular components with heavier loads; chemical connection relies on high-performance adhesives to form a molecular-level bond with the main structure, and is mostly used for lightweight decorative lines; combined connection integrates the advantages of both, achieving a balance of rigidity and flexibility at complex nodes. The industry standard "General Technical Conditions for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components" (Plan No. 2024-0232T-JC), for which Qinglong Group participated in drafting, sets out systematic provisions for the design parameters and construction specifications of various connection methods, providing a technical model for the industry.

II. Analysis of Design Essentials: From Material Properties to Engineering Practice

When designing connection nodes for UHPC decorative components, the following core elements require close attention: First, the load transfer path must be clear and controllable. Finite element analysis software is used to simulate wind loads, thermal stress, and other load conditions, ensuring that the strength reserve factor of connection points is no less than 1.5. Second, the high elastic modulus of UHPC requires connection nodes to possess a certain degree of flexibility. Qinglong's technical team adopts a composite design of "rigid framework + elastic gaskets" to effectively resolve internal stresses caused by material shrinkage and thermal deformation. In addition, anti-corrosion treatment must not be overlooked. All embedded parts produced by Qinglong use hot-dip galvanizing, combined with specialized anti-corrosion sealant, achieving node durability of over 50 years—far exceeding the industry average.

III. Full-Chain Service: Technical Expertise Built on Qinglong's 28 Years of Experience

As a national high-tech enterprise and a "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong Group carries connection technology optimization through the entire process of detailed design, manufacturing, and installation. In the detailed design phase, BIM technology enables three-dimensional visualization of connection nodes to avoid construction conflicts in advance; in production, automated production lines prefabricate UHPC components with connectors, keeping tolerances within ±2mm; on-site installation employs 3D laser scanning positioning technology to ensure installation accuracy. From the translucent concrete project at Century Plaza on Nanjing East Road to the GRC curtain wall project of the Dongguan Women and Children's Activity Center, Qinglong has validated the reliability of its connection technology through practical experience from hundreds of benchmark projects.

Connection is not only the bond of a structure, but also a promise of quality. With the mission of "Creating Beautiful Architecture," Qinglong Group integrates 28 years of technical expertise into every connection detail, providing solid support for designers to realize their creative visions and building architectural works for owners that combine safety with aesthetic appeal. Looking ahead, Qinglong will continue to drive innovation and upgrading of UHPC connection technology, committed to becoming a world-leading manufacturer of UHPC/GRC/GRG/GRP, ensuring that every connection stands the test of both time and aesthetics.
