To test the anchors or to perform an anchor pull test , the bolt is pulled with a hydraulic manifold and the displacement of the head of the bolt is measured concurrently. Tensile load is applied to the bolt via a hydraulic lift up to the specified design load to verify that neither the joint, the substrate material nor the anchor bolt fails.

Deformation of the anchor tested can also be measured to understand the relationship between force and displacement during testing. Calculate the pull-out strength for an anchor bolt embedded in concrete. To do it, use the formula F = 8psi x 3. Rust staining, increase in vibratory movement, misalignment of equipment, extraordinary displacement are some of telltale signs that are generally used in order to evaluate the present state of anchor bolts. If test fails, the client has the following options.


Pull out test of rock bolt - Duration: 5:36. Select a different type of fastener –with a higher expected resistance 2. Use the same type of fastener, but with a larger diameter 3.

Continue the test and determine the resistance. Standard Anchor Test System measures the pull strenght of anchors in concrete, woo masonry, brick and other construction materials. Super Anchor Test System for testing anchor strengths in concrete, woo masonry, and other construction materials up to 1KN (or 36lbF). After the tests are completed a report containing the test data and is provided.


Determine the failure load of anchor or verification of supporting resistance of anchorage - by loading tests ( stress test ) Tests carried out with perfectly-calibrated test equipment and by competent and trained personnel. Pull Out Testing UK provide essential testing services throughout all UK counties which includes shear testing , surface bond testing load and stress testing , anchor bolt testing for construction companies, architects, steel fabrication companies, steel erection companies, scaffold companies, health and safety companies, pipework installation companies and ship building companies. This is not destructive testing so the actual loads applied as well as the sample scale of the tests will be determined by our on-site engineers. Big Ben Bolt Test Kit Comes With Year Warranty and Free fixings pack worth £247! Rock bolts are used for support in a variety of mining and civil engineering situations.


The pull test may be used to provide a quantitative measure of the relative performance of different anchor systems in the same rock type. Anchor systems may be different mechanical anchors or different bond materials or lengths for grouted anchors. The engineer is also calling for a pull out test to be completed.


The problem is that the only company either of us know of cannot fit the test machine on the pedestal to conduct the pull out test. To calculate the Total Pull Out Strength of the entire machine, multiply the force required to pull one bolt out times the total number of bolts. When calculating Pull Out Strength it is assumed that: 1. A clean, threaded rod or bolt with a coarse surface profile is used.


To perform an anchor pull - out test , the anchor tester is fitted with a compatible stud adapter, which is connected to the anchor device. The anchor tester then applies a load with the use of a mechanical screw arrangement acting through a hydraulic load cell, which measures the load directly applied to the anchor.

The equipment is fitted to a bolt or other fixing and given a stress load test. Epoxy anchor bolt testing. Not to indict any particular mfr. IS THIS THE MOST USEFUL TOOL IN THE WORLD?


The pullout strength of a single anchor is in section D. RE: Pull - Out Rating for Concrete Achor Bolts.
