The concrete tensile creep instrument is a precision instrument used to measure the deformation of concrete over time under a constant tensile load. It can simulate the long-term stress state of concrete in actual engineering, help researchers and engineering technicians evaluate the creep performance of concrete, and provide a scientific basis for the design, construction and maintenance of building structures.
Main uses
Building materials research:
Used to study the deformation characteristics of concrete under long-term tensile loads and evaluate its creep performance.
Engineering quality inspection:
Provide concrete creep data for engineering design and construction to ensure engineering quality.
High-performance concrete research:
Study the creep mechanism of high-performance concrete and optimize the concrete mix design.
Bridge and building structure evaluation:
Evaluate the long-term deformation performance of structures such as bridges and high-rise buildings to ensure structural safety.
Applicable standards:
SL 352-2006 "Test Procedures for Hydraulic Concrete"
1. High strength and durability
High-quality spring material: The spring is made of high-quality 60Si2Mn material with high strength, long fatigue life and small permanent deformation, ensuring long-term stable operation of the equipment.
High-strength pressure plate: The pressure plate is made of high-strength steel with high rigidity and stable performance, and can withstand high-load tests.
2. Intelligent design and convenient operation
Optimized loading bracket: The loading bracket has a reasonable structural design, which is convenient for users to position the specimen, position the pressure device, fix the sensor, level and operate, and improve the test efficiency.
Customized hydraulic jack: Equipped with a customized hydraulic jack, the pressure is convenient and the pressure is easy to control and adjust, ensuring that the test process is accurate and reliable.
3. Safety and stability
Anchor fixture: The bottom of the loading bracket is equipped with an anchor fixture to ensure that the equipment is safe and stable during use and prevent accidental tipping.
Automatic pressure adjustment: After pressurizing to the rated tension, fix the adjustment nut, and the instrument displays the current pressure in real time. When the specimen is deformed due to long-term pressurization and causes insufficient pressure, the hydraulic system can be manually started to pressurize to the rated pressure and tighten the adjusting nut to ensure constant test conditions.
4. Convenient transportation and installation
Overall transportation design: The equipment is transported as a whole after assembly. Users only need to hoist and fix it before use, which saves installation time and improves convenience.
