IPC: E04G23/02
Filed: 2006-09-01
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems in concrete skeleton reinforcing work wherein there is a demand for carrying out reinforcing work in a visually confirmable state without covering the greater part of a skeleton surface, and anchor fixing is required for fall prevention when mounting a reinforcing member to the lower face of a floor slab, but anchor heads projecting from the skeleton surface are exposed in large numbers at the greater part of the skeleton surface left as a basis material, and therefore unsettled and nonusable, and furthermore driving a large number of anchors into the floor slab leads to cracks and accelerates the advance of damage.  <P>SOLUTION: In this reinforcing method, the cross-sectional shape of grooves in cutting the grooves in the skeleton surface and embedding and mounting reinforcing members, is formed into tapered groove shape made narrower on the outer surface side than the inner side. The reinforcing members are thereby embedded, coated and fixed with a filler without using after-fitted anchors to prevent the fall of the reinforcing members and to avoid causing cracks and accelerating the advance of damage of the skeleton due to anchor driving.  <P>COPYRIGHT: (C)2008,JPO&INPIT
