车修壁虎又名WedgeAnchor,此产品螺纹较长，较易安装，通常被用于重负荷设施。要获得可靠的，巨大的紧固力，就必须保证那个固定在壁虎上的夹环充分膨胀。并且膨胀夹环不可以从杆上脱落或在洞中扭曲变形。标定拉力值均在水泥强度260~300kgs/cm2的条件下测试所得，安全负荷的***大值不得超过标定值的25%。适用于混凝土及致密的天然石材，金属结构，金属型材，底板，支撑板，托架，栏杆，窗，幕墙，机器，大梁，桁条，支架等等。车修壁虎出口欧盟，需满足ETA认证要求，主要测试包括：BasicWorksRequirement1:MechanicalresistanceandstabilityCharacteristicresistancetotensionload(staticandquasi-staticloading)1Resistancetosteelfailure(tension)2.2.1NRk,s[kN]2Resistancetocombinedpull-outandconcretefailure2.2.2Rk[N/mm²]3Resistancetoconcreteconefailure2.2.3ccr,N[mm]kcr,N,kucr,N[-]4Edgedistancetopreventsplittingunderload2.2.4ccr,sp[mm]5Robustness2.2.5inst[-]6Maximumsettingtorquemoment2.2.1.2maxTfix[Nm]7Minimumedgedistanceandspacing2.2.6cmin,***in,hmin[mm]Characteristicresistancetoshearload(staticandquasi-staticloading)8Resistancetosteelfailure(shear)2.2.7V0Rk,s[kN],M0Rk,S[Nm],k7[-]9Resistancetopry-outfailure2.2.8k8[-]10Resistancetoconcreteedgefailure2.2.9dnom,f[mm]Displacementsundershorttermandlongtermloading11Displacementsundershorttermandlongtermloading2.2.100,∞[mmormm/(N/mm²)]Durability12Durabilityofmetalparts2.2.11DescriptionCharacteristicresistanceanddisplacementsforsei***icperformancecategoriesC1orC2(optional)13ResistancetosteelfailureTR049NRk,s,eq,VRk,s,eq[kN]14Resistancetopull-outRk,p,eq[N/mm2]15FractureelongationA5[%]16Factorforannulargapgap[-],17DisplacementsN,eq,V,eq[mm]衡硕检测已经为国内多家建材生产企业成功获得欧盟ETA认证证书，如有需求请联系我们。021-51860170)
