Abstract

An apparatus for detecting anchor bolt pullout strength. The apparatus includes circuitry configured to process ultrasonic measurement signals using at least one of a direct, an indirect, and a semi-direct measurement technique. Further, the apparatus comprises a first probe and a second probe connected to the circuitry, and memory for storing data detected by the first and the second probe. The memory is connected to the circuitry and a data connection connected to the circuitry and configured to communicate with an external network. An ultrasonic signal is transmitted by the circuitry through the first probe and rebounded by the second prob. The circuitry detects a time duration to receive the rebounded signal, storing the time duration to the memory, and comparing the time duration to reference measurement data. The reference measurement data may be stored in at least one of the memory and the external network.

First claim

What is claimed is:

1. An apparatus for detecting anchor bolt pullout strength, the apparatus comprising:
circuitry configured to process ultrasonic measurement signals in at least one of a direct, an indirect, and a semi-direct measurement technique;
a first probe connected to the circuitry;
a second probe connected to the circuitry;
a memory for storing data detected by the first and the second probe, the memory connected to the circuitry;
a data connection connected to the circuitry and configured to be in communication with an external network; and
a Schmidt Hammer configured to measure a compressive strength of concrete, the circuitry configured to detect measurements made by the Schmidt Hammer including a mean of rebound number readings,
wherein, if the circuitry determines that the mean of rebound number readings is less than a value or within a range of values, an ultrasonic signal is transmitted by the circuitry through the first probe and rebounded by the second probe when the first and second probes are positioned on the concrete, the circuitry detecting a time duration to receive the rebounded signal at the second probe, storing the time duration to the memory, and comparing the time duration to reference measurement data to indicate an overlap between measurement data corresponding to respective pure concrete and reinforced concrete zones of the concrete, the reference measurement data stored in at least one of the memory and the external network.

2. The apparatus according to claim 1 , wherein:
the circuitry is configured to include maximum likelihood detection to further analyze ultrasonic measurement results.

3. The apparatus according to claim 1 , further comprising:
a memory, the memory including stored reference measurement data for a plurality of reinforced concrete specimens.

4. The apparatus according to claim 1 , further comprising:
at least one of a haptic, an audio, and a visual indicator, wherein
the circuitry is configured to activate at least one of the haptic, the audio, and the visual indicator to indicate at least one of a status of the apparatus and a recommended action as a result of measurement results detected.

5. The apparatus according to claim 1 , further comprising:
at least one indicator light, wherein
the circuitry is configured to illuminate at least one indicator light to indicate at least one of a status of the apparatus and a recommended action as a result of measurement results detected.

6. The apparatus according to claim 1 , wherein:
the data connection is a physical connection.

7. The apparatus according to claim 1 , wherein:
the data connection is a wireless connection.
