Overview
The miniature drawing instrument (model KS-V3) is a testing instrument composed of a manual pump, a hollow hydraulic cylinder, a digital pressure gauge, a high voltage hose, an anchor, a tie rod, an adapter and a portable portable case. The hydraulic cylinder adopts a hollow self-reset, digital display integrated design, which can directly read the force value (KN), and has the functions of peak hold, storage, clearing, inquiry and automatic shutdown. Advanced technology, simple operation, one-year quality assurance, especially suitable for laboratory and field use.
Features
1. Hollow self-resetting, digital display integrated hydraulic cylinder design, can directly read the force value (KN).
2. With peak hold, storage, reset, query and automatic shutdown functions.
3. Simple operation and advanced technology.
4. Provide one-year quality assurance and lifetime maintenance.
5. Compact structure, easy to carry, suitable for laboratory and field use.
Principle
The miniature pullout instrument is pressurized by a manual pump, and the hydraulic oil is transported to the hollow hydraulic cylinder through the high voltage hose to push the piston to generate a pulling force. The pulling force is transmitted to the tested anchor through the pull rod and the anchor, so that it can withstand the pulling force. The digital pressure gauge displays and records the applied force value in real time, and the maximum pulling force of the anchor can be accurately measured through functions such as peak holding.
Applications
It is suitable for testing the pull-out force of various anchors, steel bars (planting bars), expansion bolts, chemical anchors and other anchors, and can also be used for on-site pull-out force testing (test) of Glass curtain walls
Standards
GB 50367-2013 "Code for Design of Reinforcement of Concrete Structures", GB 50330-2013 "Technical Specifications for Building Slope Engineering", JGJ 120-2012 "Technical Specifications for Building Foundation Pit Support", CECS 22:2005 "Technical Specifications for Geotechnical Anchors (Cables) ", GB 50001-2011 "Code for Design of Building Foundation", JGJ 145-2013 "Technical Specifications for Rear Anchorage of Concrete Structures", GB 50550-2010 "Code for Construction Mass Acceptance of Building Structure Reinforcement Engineering", GB 50203-2011 "Code for Construction Mass Acceptance of Masonry Structure Engineering"
Steps
1. Select the appropriate anchors, pull rods, and adapters according to the tested anchors, and assemble them into the hydraulic cylinder.
2. Connect the hydraulic cylinder to the manual pump through the high voltage hose.
3. Put the assembled drawing instrument into the tested anchor and ensure that the anchor is fixed firmly.
4. Open the digital pressure gauge and press the reset button to clear.
5. Operate the manual pump for smooth pressurization, and observe the pressure gauge indication at the same time.
6. When the anchorage breaks or reaches a predetermined tension, stop pressurizing.
7. Record or query the maximum force value (KN) stored by the peak hold function.
8. Remove the pressure, disassemble the instrument, and complete the test.
Notice
• Please read the manual carefully before use to ensure correct operation.
• Ensure that the connecting parts (e.g. quick connectors, anchors) are firmly installed and leak-free.
• The pressurization process should be smooth and uniform to avoid Impact loads.
• During testing, personnel should stay away from the direction in which the tested part may fly out to ensure safety.
Do not exceed the maximum range of the instrument (30KN).
• Regularly check the status of the instrument and keep it clean.
• When the digital pressure gauge is low, please charge it through the USB port in time.
• If the instrument malfunctions, please contact a professional for repair.
