Title:
STRUCTURE FOR REINFORCING CONCRETE MEMBER AND REINFORCING METHOD
Document Type and Number:
WIPO Patent Application WO/1999/014453
Kind Code:
A1
Abstract:
A structure for reinforcing a concrete member and a reinforcing method, in which reinforcing sheets are disposed along concrete members such as poles, beams, walls, floors, and the reinforcing sheets are bonded to the concrete members to be reinforced or to anchors fixed to other concrete members around the concrete members to be reinforced. The anchor comprises a large number of reinforcing fibers. The fibers are bundled at a part of them in the longitudinal direction, and the unbundled portions are spread along the concrete members. The reinforcing sheets are placed on the fibers and superposing and bonding the reinforcing sheet to bonded to them. The anchor and the reinforcing sheet are preferably made of reinforcing fibers such as carbon fibers, aramid fibers, or glass fibers. Because the reinforcing members can be fixed through the anchor, both ends of each reinforcing member can be fixed reliably and can reliably exhibit the effect of reinforcing the concrete members.
