GLASS FIBER-MADE SHEAR REINFORCEMENT MATERIAL AND REINFORCEMENT METHOD FOR EXISTING CONCRETE STRUCTURE USING SHEAR REINFORCEMENT MATERIAL

摘要

PROBLEM TO BE SOLVED: To solve the problem that when pure reinforcing bars are used as a shear reinforcement material, air is possibly confined since a grout material is sent in between the shear reinforcement material and an insertion hole from an opening side, and filling may not be complete even when an overflow can be confirmed.;SOLUTION: A glass fiber-made shear reinforcement material is a cylinder body (2) having a penetrating shaft hole (1), and has a main anchor (3) outside one end and a sub anchor (4) outside the other end. A filler (9) is made to pass through the shaft hole (1) of the reinforcement material (5) and then to flow out into a blind hole (7) from its inner end. Consequently, air is prevented from being confined. A shear reinforcement method is to achieve shear reinforcement on a concrete structure (6) in the absence of a work space behind it using the glass fiber-made shear reinforcement material (5).;COPYRIGHT: (C)2014,JPO&INPIT
