In modern engineering such as bridge construction, high-speed railways, and large buildings, prestressing technology is widely used. Anchors, fixtures, and connectors are the core components of prestressing systems, and their static anchoring performance directly affects the long-term safety and stability of engineering structures. As a professional manufacturer in the field of material mechanics performance testing in China, Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") has officially launched an upgraded version of the microcomputer controlled static load anchoring testing machine series with profound technical accumulation, providing high-precision and fully automatic testing solutions for the production inspection, on-site acceptance, and type testing of prestressed anchors.
The core of static load anchoring test lies in accurately measuring the anchoring efficiency coefficient (η a) and ultimate tensile force (Fm) to verify the reliability of the anchor assembly under actual working conditions. The Xin Guang anchoring testing machine is designed strictly in accordance with national and industry standards, and has the following outstanding advantages:
1. Large tonnage bearing capacity: In response to the testing requirements of different specifications of anchors, Xinguang can provide various tonnage models such as 5000kN, 6500kN, and even 10000kN to meet the static anchoring performance testing of anchors from 3 to 16 holes. The host adopts a four column horizontal structure with strong frame rigidity and high stability, ensuring the authenticity and reliability of test data during large tonnage loading.
2. High precision measurement and control system: equipped with high-precision load sensors and displacement measurement systems, the accuracy of the test force indication is better than ± 0.5% (0.5 level accuracy), the load measurement resolution is as high as 1/300000, the full range is not divided into gears, and automatic shifting ensures accurate measurement throughout the entire process. The displacement measurement range is 0-200mm, with a resolution of up to 0.001mm, which can accurately capture the small deformation of the anchor during the loading process.
3. Fully automatic closed-loop control: A fully automatic closed-loop speed control system is composed of a wide speed range digital servo valve and microcomputer measurement and control technology. Support multiple control modes such as constant rate load control, constant load control, and constant displacement control. The control modes can be randomly/arbitrarily switched, and the PID parameters can be adjusted online. Real time display of force displacement curve during the experiment, automatic calculation of anchoring efficiency coefficient and total strain, and automatic generation of testing report that meets standard requirements.
4. Multiple safety protection mechanisms: The equipment is equipped with multiple safety measures such as pressure protection, oil temperature protection, and piston limit protection. At the same time, a dedicated safety protection sand box is provided to effectively prevent the risk of splashing when the steel strand breaks, ensuring the safety of operators and equipment.
The Xin Guang anchoring testing machine fully complies with the following national standards and industry specifications:
-GB/T14370-2015 "Anchors, clamps and connectors for prestressing tendons"
-JT/T329-2010 "Anchors, Fixtures, and Connectors for Prestressed Steel Strands in Highway Bridges"
-TB/T3193-2016 Technical Conditions for Anchors, Fixtures, and Connectors for Prestressed Reinforcement in Railway Engineering
The product is widely used in the following fields:
-Bridge engineering: Testing the static anchoring performance of prestressed anchorages to ensure the safety and reliability of the bridge prestressing system
-Rail transit: Testing of prestressed structures serving high-speed railways, subways, and other engineering projects
-Quality inspection agency: As the core equipment for third-party testing and certification, it carries out quality supervision and inspection of anchor products
-Water conservancy and electric power: performance testing of steel strand anchorage used in large-scale water conservancy projects and power infrastructure construction
