Overview of LRMG-40 Rear Anchoring Strength Tester
The LRMG-40 intelligent post anchoring strength tester (referred to as the tester) is suitable for testing the strength of concrete in the strength range of C10 to C80. As a new micro damage method, the post anchoring method has the advantages of high detection accuracy, minimal structural damage, and simple and convenient operation. It has broad application prospects and greatly improves the quality inspection technology level of construction projects in China.
The detector adopts an electromechanical integrated design, consisting of a spiral pressurized oil pump, sensors, digital pressure instruments, anchoring components, drilling machine, injection positioning disc, and reaction support ring. Due to the use of high-precision and high impedance sensors, temperature drift and other electromagnetic interference can be prevented, and the sampling accuracy is more than twice that required by regulations; The integrated intelligent pressure instrument has a compact appearance and high compatibility in program design, allowing for direct observation and data storage. The detector adopts a spiral pressure feeding method to continuously and uniformly apply pressure to the anchor, ensuring the authenticity and effectiveness of the detection data. This machine has the characteristics of light weight, high tensile strength, easy to operate handle, and convenient to use. It can also be applied to other detection methods to meet various pulling force detection needs.
The LRMG-40 type rear anchoring strength tester is based on the standard:
JGJ/T208-2010 Technical Specification for Testing Concrete Compressive Strength by Post Anchoring Method
CECCS69:94 "Technical specification for testing concrete strength by post installation pull-out method"
JGJ110-97 "Inspection Standard for Bonding Strength of Decorative Bricks in Building Engineering"
JGJ126-2000 "Code for Construction and Acceptance of Exterior Wall Decorative Brick Engineering"
