Innovative Flat Prestressed Anchorages: BICP Subsidiary Anhui Shente Receives National Utility Model Patent

Introduction

This article is an official version adapted from the original WeChat content, revised to align with BICP's brand messaging, compliance requirements, and resource center format. It focuses on the Taiku, Taiping, and Shente New Materials solutions for cold chain warehouse scenarios, highlighting project pain points, solution pathways, value indicators, and application boundaries. Specific projects require professional review based on loads, column grids, geological conditions, construction schedules, operational needs, and regulatory approvals.

Client Concerns

• Traditional cold storage facilities often have small column grids, resulting in dense internal columns that hinder rack layout, forklift movement, and future automation upgrades.
• Expansion joints, beam heights, and insulation areas collectively impact construction costs, usable storage volume, and operational energy consumption.
• Cold storage projects require integrated planning of structure, insulation, racking, and operational efficiency during the design phase.

Solution Highlights

• Adopt a large-span (10–14 m) post-tensioned flat slab structural system to improve spatial efficiency within the warehouse.
• For building lengths up to 120 m, optimize expansion joint placement based on project conditions to reduce the cost and operational impact of double walls, columns, and insulation.
• Use flat slab construction to reduce structural depth and insulation area, increasing usable storage volume and lowering energy consumption.
• Conduct 3D BIM coordination with racking systems during the planning and design stage to prepare for future mechanization and automation.
• Taiping offers three integrated floor system solutions: post-tensioned integrated floor, UHPC integrated floor, and UHPC long-lasting repair.
• Post-tensioned integrated floors are suitable for industrial facilities and underground garages, but not for cold storage applications.
• UHPC integrated floors and UHPC long-lasting repair can be used in cold chain warehouses, industrial facilities, and underground garages.
• Reduce floor joint cutting by up to 80%, minimizing joint edge damage, dust, step displacement, and operational disruptions from maintenance.

Main Content (Official Version)

In recent years, Beijing Yintai JianGou Technology Co., Ltd. (hereinafter referred to as BICP) has continuously strengthened its independent innovation capabilities. As the company has grown and its technical expertise has improved, it has actively pursued various technological innovations. Anhui Shente Prestressed Materials Co., Ltd. (hereinafter referred to as Anhui Shente), established in 2020, is a wholly-owned subsidiary of BICP. It specializes in the production of various specifications of prestressed anchorages, corrugated pipes, and associated tensioning, release, and grouting equipment. Its products are primarily used in professional prestressed anchorage systems for cold chain warehouses, logistics storage, floors, stadiums, bridges, railways, and other projects. Anhui Shente has rapidly developed, assembling a professional team integrating R&D, production, sales, application, and maintenance, and has become an industrial enterprise providing full-process prestressed solutions including design, R&D, manufacturing, sales, and maintenance. Adhering to the principle of "pursuing excellence and quality first," the company serves its clients with high product quality, a strong corporate reputation, and superior professional services.

While focusing on the R&D and engineering practice of prestressed products, Anhui Shente places great emphasis on independent innovation, maintaining long-term investment in R&D and actively carrying out core technological innovations. Recently, good news came: a "Corrosion-resistant and Rust-proof Prestressed Flat Anchorage for Cold Storage" independently developed and applied by Anhui Shente was granted a utility model patent by the China National Intellectual Property Administration.

According to the introduction, this patent is a corrosion-resistant and rust-proof prestressed flat anchorage specifically designed for cold chain warehouses, floors, and logistics storage projects. When prestressed strands are arranged in slab structures, flat anchorages allow the strands to be laid in a flat radial pattern to avoid increasing slab thickness, thereby reducing the thickness of post-tensioned members.

Compared with existing technologies, the advantages and positive effects of this utility model patent for prestressed flat anchorages are as follows:

Patent product illustration: 1. Flat trumpet; 3. Protective cap; 8. Anchor plate; 9. Wedge; 12. Strand; 14. Corrugated pipe connector; 15. Corrugated pipe; 16. Spiral reinforcement.

The protective cap protects the strands. The mounting holes on the flat trumpet facilitate connection between the trumpet and the cap using bolts, improving sealing. The cap allows anti-corrosion grease to enter the grease zone, preventing corrosion of the internal strands and anchorages, thereby extending the service life of the structure.

The tapered holes in the anchor plate cooperate with the wedges, using a wedge action to clamp and anchor the strands. The trumpet and spiral reinforcement are embedded in concrete to form a load-bearing component that meets the requirements for transferring prestress. The trumpet bears the anchor stress and transfers it to the prestressed concrete structure, while the spiral reinforcement confines the concrete in the anchorage zone, resists splitting, and improves the ultimate strain of the axially loaded reinforced concrete member.

This flat anchorage has been put into use and successfully applied in over 20 projects, including Qingdao Art Bay, Hangzhou Xianfeng, Zibo Railway Station, Yiwu Free Trade Zone, Shenzhen Yantian Port, Wenan Warehouse No. 3, Changsha Wanwei, Qingdao Ocean University, Suning SCO, Urumqi Railway Port, Qingdao Free Trade Port International Cold Chain Logistics Trading Center, Northeast Asia Aquatic Products Trading Center, Luhaifeng Cold Storage, California Cold Storage, Shifang Floor, Ningbo Meishan Port, and Zhanjiang Tianhe Cold Storage.

This patent reflects the professional technical capability of Anhui Shente's R&D team and demonstrates BICP's strength in prestressed technology. It not only shows our high regard for intellectual property protection but also provides momentum for BICP's future development, further enhancing the company's technical expertise, product stability, and core competitiveness. Moving forward, Anhui Shente will continue to deepen product reform, steadfastly promote the development of prestressed anchorage system technology, increase R&D and production investment, accelerate product innovation, facilitate the transformation of achievements, and improve product quality, providing strong product support for BICP's continued growth.

Application Boundaries and Publication Notes

• Taiku is suitable for large-span post-tensioned flat slab structures in cold chain warehouses. Specific column grids, loads, expansion joint optimization, and floor-to-floor heights should be reviewed based on project conditions.
• Taiping must distinguish among its three technical lines: post-tensioned integrated floors are applicable to industrial facilities and underground garages; for cold storage scenarios, UHPC integrated floors or UHPC long-lasting repair should be used, not post-tensioned integrated floors.
• Shente New Materials, as material and component support, should be selected in conjunction with the specific structural system, floor system, and project conditions.
