由浙江省建筑科学研究所研制的ZHQ—60A型智能混凝土强度拉拔仪是一种混凝土质量实地检测的新型仪器,通过检测硬化混凝土的抗拔力,能直接确定混凝土的抗压强度,其相关系数达0.96以上,检测一次只需10分钟左右,即可得出被测混凝土强度值,测试中对被测混凝土表面破坏极少,属微破损检测。测试数值直接由智能仪表显示,读数直观,数据准确,并具备自动判别及自动保持混凝土极限抗拔力值功能。应用该仪器检测混凝土强度,比回弹法、超声波法等检测精度高,比钻芯取样法破损小,速度快,不影响被测结构的强度。该
The ZHQ-60A intelligent concrete strength drawing instrument developed by Zhejiang Institute of Building Science is a new type of instrument for concrete testing on the spot. By measuring the pullout resistance of hardened concrete, the compressive strength of concrete can be directly determined. The coefficient is more than 0.96. The test takes only about 10 minutes at a time, and the measured concrete strength value can be obtained. The surface damage to the tested concrete is minimal during the test, which is a micro-damage detection. The test value is directly displayed by the smart meter, the reading is intuitive, the data is accurate, and it has the function of automatically distinguishing and automatically maintaining the concrete ultimate pull-out force value. The application of the instrument to detect the concrete strength is more accurate than the rebound method, ultrasonic method, etc. It is less damaged and faster than the core drilling method and does not affect the strength of the tested structure.
