Abstract
A U-bolt (1) according to the present invention includes: a pair of shaft parts (111) arranged in a first direction and extending in a second direction orthogonal to the first direction; and one screw part (12) provided on an apex side and one or more screw parts (12) provided on a tip side in each of the pair of shaft parts (111).
Claims20
A U-bolt for fastening a fastener object by using a nut, comprising:
- a pair of shaft parts arranged in a first direction and extending in a second direction orthogonal to the first direction;
- and
- one screw part provided on an apex side and one or more screw parts provided on a tip side in each of the pair of shaft parts.
A detection device for detecting a descent of a nut coupled to a U-bolt for fastening a fastener object, comprising:
- a U-bolt including a sensor for measuring a distance to an object and a transmission unit for transmitting a measurement result obtained by the sensor;
- a master unit that includes a reception unit for receiving the measurement result transmitted from the transmission unit,
- a control unit for determining whether the nut has descended or not based on the measurement result, and
- an alert issuing unit for issuing an alert when the control unit determines that the nut has descended.
A detection method for detecting a descent of a nut coupled to a U-bolt for fastening a fastener object, comprising the steps in which a detection device:
- measures a distance to an object;
- transmits a measurement result;
- receives the measurement result;
- determines whether the nut has descended on the basis of the measurement result;
- and
- issues an alert when it is determined that the nut has descended.
