The client is a company specializing in the research, development, and production of prestressed anchoring devices, clamps, connectors, and other products. These products are widely used in various fields such as highway bridges, railway engineering, large venues, and water conservancy facilities. As crucial load-bearing components in the prestressed system, the quality of anchoring devices directly impacts the safety and durability of engineering structures.
In recent years, with the continuous strengthening of national supervision over the quality of infrastructure projects and the full implementation of the new standard GB/T14370-2015 "Anchors, Grips, and Couplers for Prestressed Tendons", the products of this enterprise need to pass stricter inspections. Especially when bidding for large-scale projects, having authoritative type inspection reports and CCPC (Certification for Communication Products) certificates becomes the core competitiveness of the enterprise, which places higher demands on its testing and inspection capabilities.
Xinguang Plan
1. Strictly comply with the requirements of the new national standard
The equipment is designed in strict accordance with standards such as GB/T14370-2015 "Anchors, Grips and Couplers for Prestressed Tendons" and GB/T2611-2022 "General Technical Conditions for Testing Machines", and can accurately complete the following core testing items:
- Determination of anchoring efficiency coefficient: By accurately measuring the ratio of the ultimate tensile force of the anchoring device under static load to the theoretical breaking force of the steel strand
-Ultimate tensile force measurement: Measure the tensile force of the assembled anchor components when they reach failure
- Total strain measurement: Accurately record the total elongation of the anchor during the loading process up to its limit
-Static load anchoring performance test of anchor clamps: comprehensively verifying the reliability of the anchoring system
2. Fully automatic closed-loop control, ensuring precise and stable detection
The microcomputer-controlled electro-hydraulic servo loading system possesses the following core functions:
-Multi-mode control: Equipped with two control channels for load and displacement, it supports equal-rate load control, equal-rate stress control, and equal-rate displacement control, with seamless switching between control modes
-PID adaptive adjustment: PID parameters can be adjusted online to ensure the smoothness and accuracy of the loading process
-Full-range without gear shifting: The test force measurement range covers 2%-100%FS, with automatic gear shifting, maintaining high accuracy throughout the entire process
-Dual force measurement system: It can be equipped with a primary and a secondary load sensor according to needs, achieving wide-range and high-precision measurement
3. Professional structural design, tailored specifically for anchoring tests
-Horizontal mainframe structure: Adopting a horizontal frame structure, with stretching spacing customized according to customer needs (typically above 3000mm), meeting the large-stroke testing requirements for anchor assembly parts and connectors
-Front clamp jack: Equipped with a dedicated front clamp jack, it is convenient to install and efficient to operate
-Portable high-pressure oil source: The oil source system is designed flexibly, facilitating maintenance and operation
4. Intelligent measurement and control software, empowering quality management with data
The dedicated measurement and control software based on the Windows platform boasts powerful data analysis and reporting capabilities:
-Real-time display of multiple curves: force-displacement, force-time, displacement-time, and other curves are plotted simultaneously, making the test process clear at a glance
-Multicolor curve comparison: Supports comparative analysis of multicolor curves for grouped samples, facilitating the assessment of product consistency
-Analysis of any segment area: Any segment on the test curve can be selected for zoom analysis, facilitating in-depth research
-Database management: Automatically store test data, support historical query, export, and local network communication, and meet the needs of digital quality management
5. Multiple safety protections ensure worry-free operation
-Pressure overload protection: automatic unloading when exceeding the full range
-Piston limit protection: automatic shutdown at extreme position
-Oil temperature monitoring and protection: high temperature alarm and shutdown
- Emergency stop button: Interrupts the test at any time to ensure the safety of both the machine and personnel
