PRESTRESS CONCRETE STRUCTURE PROVIDING EXPOSED TENDON AND TENSIBLE FORCE MEASUREMENT METHOD

The present invention relates to a prestressed concrete structure having an exposed tendon and a tension measurement method using the same. The prestressed concrete structure is composed as follows. An exposed chamber is formed by opening a portion of the bottom surface of a concrete member to expose a portion of a tendon inserted into the concrete body for prestressing to the outside. The tension of the tendon is measured by connecting a measurement sensor to the exposed chamber. The tendon exposed from the exposed chamber is supported by two hinge parts. A chamber door is formed in the exposed chamber and selectively opens and closes the exposed chamber. Side panels for reinforcing strength are formed on the corners of the exposed chamber. The tension measurement method using the prestressed concrete structure simply measures the prestressing tension of the tendon by exposing a portion of the tendon to a bottom surface, enables the easy repair and replacement of the measurement sensor, and improves measurement accuracy by directly connecting the measurement sensor to the tendon.
