Overview
XH-DH5 type masonry mortar strength point load instrument is a special instrument developed and produced by Tiandi Spark brand according to GB/T50315-2011 "Technical Regulations for on-site inspection of masonry engineering", which is used for masonry mortar strength detection. Its characteristics are that it can be tested directly on site or in the laboratory, and does not affect the wall's mechanical performance. It has the advantages of easy detection, convenient operation, and high-precision testing. It meets the needs of on-site quality control of masonry engineering and mass identification and evaluation of old and ancient houses.
Features
1. It is composed of worm gear, worm mechanical loading system, pressure sensor and intelligent digital pressure display, with reasonable structure.
2. Sensor mounted on the loading system base, peak display and loading system through the wire connection, easy to operate.
3. The intelligent digital pressure display maintains maximum load to ensure accurate testing.
4. Range 0-3KN, Maximum Range 5KN, Maximum Travel 30mm, Power supply voltage 5V, Net weight 4.8kg, Portable and practical.
Principle
When the point load meter is working, the pre-taken mortar sample is placed on the indenter, and the handle is slowly turned clockwise manually to move the lifting screw down and load the mortar sample on the top of the head to generate a pressure load. Then slowly and evenly apply the load until the sample is damaged. At this time, the intelligent digital pressure display automatically maintains and displays the maximum load value.
Applications
Masonry engineering site quality control, old house mass appraisal, ancient house mass assessment
Standards
GB/T50315-2011 "technical regulations for on-site inspection of masonry engineering"
Steps
1. Place the pre-taken mortar sample on the indenter of the point load instrument.
2. Manually turn the handle slowly clockwise to move the lifting screw down and load the mortar sample.
3. Apply the load slowly and evenly until the mortar sample breaks down.
4. Read the maximum load value maintained on the intelligent digital pressure display.
Notice
• Load should be applied slowly and evenly to avoid sudden loading.
• Ensure that the specimen is placed stably to prevent slippage.
• Check whether the device connection is firm before use, and whether the Power supply voltage meets the 5V requirement.
• Pay attention to safety during the test to avoid splashing of sample fragments.
