Innovative Prestressed Flat Anchor Continues to Empower the Industry: BICP's Subsidiary Anhui Shente Granted National Utility Model Patent

Introduction

This article is an official website version adapted from original content, revised for brand consistency, compliance, and resource center formatting. It focuses on Taiku, Taiping, and Shente new materials in cold chain warehouse scenarios, highlighting project pain points, solution paths, value indicators, and application boundaries. Specific projects require professional review based on loads, column grids, geology, construction schedule, operation methods, and drawing approvals.

Client Concerns

• Traditional cold storage column grids are small, with dense interior columns affecting rack layout, forklift traffic, and automated storage upgrades.
• Expansion joints, beam height, and insulation area collectively impact construction cost, effective storage capacity, and operational energy consumption.
• Cold storage projects require integrated planning of structure, insulation, racking, and operational efficiency at the concept stage.

Solution Highlights

• Adopt a 10–14 meter large column grid post-tensioned flat slab structural system to improve interior space organization efficiency.
• For building lengths up to 120 meters, optimize expansion joints based on project conditions to reduce the impact of double walls, columns, and insulation on cost and operations.
• Use flat slab floors to reduce structural height and insulation area, increasing effective storage capacity and lowering operational energy consumption.
• Conduct 3D BIM coordination with racking systems during planning and design to reserve conditions for future mechanized and automated operations.
• Taiping offers three integrated floor system solutions: post-tensioned integrated floor, UHPC integrated floor, and UHPC long-lasting repair.
• Post-tensioned integrated floor is suitable for industrial facilities and underground garages, not for cold storage.
• UHPC integrated floor and UHPC long-lasting repair can be used in cold chain warehouses, industrial facilities, and underground garages.
• Reduce floor joint cutting by 80%, minimizing edge damage, dust, step displacement, and operational disruptions from maintenance.

Main Content (Official Website Version)

In recent years, Beijing Yintai JianGou Technology Co., Ltd. (hereinafter referred to as BICP) has continuously strengthened its independent innovation capabilities. With the gradual expansion of company scale and continuous improvement of professional technical level, BICP actively carries out various technological innovation works. 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 various specifications of prestressed anchors, corrugated pipes, and supporting tensioning, release, and grouting equipment. Its main products are applied in cold chain storage, logistics warehousing, flooring, stadiums, bridges, railways, and other professional prestressed anchorage system projects. Anhui Shente has rapidly developed, forming a professional team integrating R&D, production, sales, application, and maintenance, becoming an industrialized enterprise providing full-process prestressed solutions including design, R&D, manufacturing, sales, and maintenance. Adhering to the principle of "Casting Brilliance, Quality First," it serves various enterprises with high product quality, good corporate reputation, and excellent professional services.

While focusing on the scientific research 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 technology innovation. Recently, good news came that a "Cold Storage Special Anti-Corrosion and Anti-Rust Prestressed Flat Anchor" independently developed and applied by Anhui Shente was granted a utility model patent by the National Intellectual Property Administration. According to the introduction, this patent is a cold storage special anti-corrosion and anti-rust prestressed flat anchor, specifically used in cold chain storage, flooring, logistics warehousing, and other projects. When prestressed strands are arranged in slab structures, to avoid increasing slab thickness due to strand placement, flat anchors can be used to arrange the strands in a flat radial pattern, allowing the post-tensioned member to be thinner.

Compared with existing technologies, the advantages and positive effects of this patented prestressed flat anchor 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 flat trumpet and the protective cap using bolts, improving sealing. The protective cap allows anti-corrosion grease to enter the anti-corrosion grease area, preventing corrosion of internal strands and anchors, thereby extending the building's service life. The tapered holes in the anchor plate cooperate with wedges to clamp and anchor the strands using a wedge action. The trumpet and spiral reinforcement are embedded in concrete to form a load-bearing component, meeting the requirements for bearing and transferring prestress. The trumpet bears the anchor stress and transfers it to the prestressed concrete structure, while the spiral reinforcement constrains the concrete under the anchor and resists concrete splitting, limiting lateral deformation of the core concrete and increasing the ultimate strain of axially compressed reinforced concrete members.

This prestressed flat anchor has been put into use and successfully applied in more than 20 projects, including Qingdao Art Bay, Hangzhou Xianfeng, Zibo Railway Station, Yiwu Free Trade Zone, Shenzhen Yantian Port, Wen'an No. 3 Warehouse, Changsha Wanwei, Qingdao Ocean University, Suning Shanghe, 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 Flooring, Ningbo Meishan Port, Zhanjiang Tianhe Cold Storage, etc.

This patent reflects the professional technical capability of Anhui Shente's R&D personnel and demonstrates BICP's strength in prestressed technology. It not only shows our high regard for intellectual property protection but also accumulates momentum for BICP's future development, further enhancing the company's professional technical content, product stability, and core competitiveness. Going forward, Anhui Shente will continue to deepen product reform based on existing patents, unswervingly promote the vigorous development of prestressed anchorage system product technology, increase R&D and production investment, accelerate product innovation, promote achievement transformation, improve product quality, and provide strong product support for BICP's further development.

Application Boundaries and Release Notes

• Taiku is suitable for large column grid post-tensioned flat slab structural solutions in cold chain warehouses. Specific column grids, loads, expansion joint optimization, and floor height control should be reviewed based on project conditions.
• Taiping must distinguish three technical lines: post-tensioned integrated floor is suitable for industrial facilities and underground garages; cold storage scenarios use UHPC integrated floor or UHPC long-lasting repair, not post-tensioned integrated floor.
• Shente new materials, as material and component support, should be matched with the specific structural system, floor system, and project conditions.
