Abstract
A hybrid permanent anchor is proposed. The hybrid permanent anchor includes: a fixed body disposed between a compression part and a tension part and coupling the compression part and the tension part to each other; the tension part coupled to a front end of the fixed body and transmitting tension to the permanent anchor when tensile stress is generated; the compression part coupled to a rear end of the fixed body and transmitting compressive force to the permanent anchor when compressive stress is generated; a PC steel strand coupled to a rear end of the compression part and having a protective pipe thereon; and an anchor head part fixing the permanent anchor to a structure.
Claims5
A hybrid permanent anchor for distributing and reducing a concentrated load in the permanent anchor, comprising:
- a fixed body disposed between a compression part and a tension part and coupling the compression part and the tension part to each other;
- the tension part coupled to a front end of the fixed body and transmitting tension to the permanent anchor when tensile stress is generated;
- the compression part coupled to a rear end of the fixed body and transmitting compressive force to the permanent anchor when compressive stress is generated;
- a PC (prestressed concrete) steel strand coupled to a rear end of the compression part and having a protective pipe thereon;
- and
- an anchor head part fixing the permanent anchor to a structure.
