1. An overview of the microcomputer-controlled static load anchoring performance testing machine

1. Main purpose and scope of application

1) This series of products are mainly used for static load anchoring and low-cycle load performance test of steel strand-anchorage in the construction of railway bridges, water conservancy, electric power and other infrastructure. It is suitable for GB/T14370 "Anchors, Fixtures and Connectors for Prestressed Tendons" to determine whether the mechanical properties of the steel strand anchors can meet the specified requirements.

2) This testing machine is dedicated to the static load anchoring performance test of prestressed fixtures and anchors. It can detect the static load anchoring efficiency coefficient of the steel strand anchor assembly and the total strain when the measured ultimate tensile force is reached . The testing machine is mainly used Fixtures, anchors manufacturers, highway construction, construction quality inspection stations and other units conduct quality inspection and scientific research use.

2. The performance characteristics of the microcomputer controlled static load anchoring performance testing machine

1) The machine is an integrated product of mechanical, electrical, hydraulic, and computer. The host uses hydraulic loading to apply test force to the anchor assembly. The test force is measured by the sensor, the measurement and control card performs data collection, and the computer screen displays the test force and test curve. . The machine can strictly comply with the national standard GB/T14370-2007 "Anchorage, fixture and connector for prestressing", JT329.1-1997 "Specification series of YM anchorage and connector for highway bridge prestressed steel strand", JT329 .2-1997 "Test Methods and Inspection Rules for Anchors and Connectors for Prestressed Steel Strands of Highway Bridges" shall carry out quality inspection of anchors and fixtures. The electrical measurement and software data processing parts all adopt contemporary advanced technology, with a high technical level, and the product performance is stable and reliable.

2) This series of products have reasonable design, convenient use, and high accuracy of measurement and control. The electro-hydraulic servo closed loop is used to realize the test process control of constant velocity loading and load retention, ensuring the stable and reliable loading rate, providing load retention accuracy, and avoiding the influence of human factors on the test results. The modified system has a large tonnage loading mechanism and an automatic force detection system, which can meet the requirements of static load anchoring performance testing. The modified system adopts microcomputer automatic control, automatic collection, storage and processing of test data, and the computer screen displays real-time display during the test. Test curve, detect the change of force value and displacement, automatically calculate the shrinkage and print the test curve and test data.

2. The main technical parameters of the microcomputer-controlled static load anchoring performance testing machine

 Anchor customers prepare by themselves according to the test requirements, self-made anchor pads or self-purchased anchor pads with round and square holes: 3, 4, 5, 6, 13, 15, 19, 22, 24 holes; when purchasing Please be clear.
