Title:
FIXING IMPLEMENT AND PRE-STRESSED CONCRETE
Document Type and Number:
WIPO Patent Application WO/2022/131174
Kind Code:
A1
Abstract:
[Problem] A wedge-type fixing implement according to the present invention has sufficient strength against diameter-expansion deformation in a barrel member resulting from a wedge action, without the barrel member causing any corrosion problems. [Solution] The present invention includes: a barrel member 12 that is constituted by resin or mortar and has tapered through-holes 14; a plurality of wedge members 20 that have tapered outer circumferential surfaces 20A which slide into inner circumferential surfaces 14A of the through-holes 14, and that work together to grip a wire 110; and fibers 16 that serve as reinforcing members extending in the circumferential direction of the barrel member in order to suppress radius-expansion deformation of the barrel member 12.
