NON-DESTRUCTIVE APPARATUS, SYSTEM AND METHOD FOR DETERMINING PULL-OUT CAPACITY OF ANCHOR BOLTS

摘要

Embodiments include an apparatus for determining a pull-out capacity of a bolt disposed in concrete. The apparatus includes control processing circuitry and a Schmidt hammer electrically connected to the control processing circuitry. The Schmidt hammer is configured to strike the bolt during a test event and to record a rebound value for the bolt. The control processing circuitry is configured to calculate an estimated pull-out strength for the bolt using the rebound value of the bolt that resulted from the test event, a predetermined bolt diameter, a predetermined bolt embedment length in the concrete, and an estimated predetermined strength of concrete. The apparatus also includes a remote computer configured to communicate with the control processing circuitry and to store an estimated pull-out strength of the bolt. The control processing circuitry includes a memory and a database.
