The anchorage may be of any type that is lot wedge type, expansion shell type, etc. Standard pull tests have sometimes been employed, but they provide no information on the anchorage near the top of the bolt. The purpose of the test is to measure the maximum tensile strength of tile on concrete. method for conducting pull-out test on anchor bars and rock bolts is a full-column-grouted rock bolt or bar with cement-sand grout or resin and rock bolt is ungrouted mechanically anchored bolt. Pull off test on tile. An alternative, first described more than 25 yrs ago in the U.S., is the short-encapsulation pull test (SEPT). anchorage test for fully grouted bolts. Onsite testing checks the structural strength of an anchoring system or base material. With this test, the bolt is installed with only a short (1 ft or Pull out test on anchor bolt The purpose of the test is to apply a specific tensile load to an anchor bolt in order that the bolt can sustain such test condition for a period of time. The pull out assembly is pulled with a lump of concrete, which is subjected to tension and shear and the force required to pull out is related to shearing strength of concrete and Following failure modes are possible: cracks in the base material, steel failure, concrete cone failure or pull out failure. Our tests are carried out with regularly calibrated test equipment and by expert Hilti engineering staff. The Code of Practice sets out the roles and responsibilities of all stakeholders in the use of construction fixings including testers for whom it defines the test regimes. BS8539 Standard. The Pull out test is passed, if the design load or the recommended load is reached, without any obvious damages. The test was carried out on three 12×12×36 cm specimens, while the average values of three measurements are shown in this study. The test sample is subjected to increasing tensile stress until failure occurs. Designed to provide recommendations for the safe and effective selection and installation of anchors for use in masonry and concrete, this code of practice improves the level of safety and eliminates the potential for fixing failure. Deformation of the anchor tested can also be measured to understand the relationship between force and displacement during testing. We adhere to one of the most important codes of practice to affect the pull out testing industry, BS8539 Standard. For more information contact you local Hilti team and we’ll be happy to help.
