A gap adjustment member includes a main body and an outward protrusion. The main body portion has a diameter less than or equal to the diameter of a mounting hole. The outward protrusion protrudes outwardly on an outer perimeter surface of the main body portion, the number of the protrusions being less than or equal to the number of recessed grooves. A diameter of a circumscribing circle, which circumscribes the main body portion and passes a projecting end of the protrusion, and a crossing point, in which a line that passes the projecting end and a center of the main body portion intersects the outer perimeter surface of the main body portion, and which is a crossing point on the opposite side of the projecting end, is configured to be greater than the diameter of the mounting hole and less than or equal to the diameter of an annular groove.

The present invention relates to a repair and reinforcement method for preexisting structures such as buildings or the like, and in particular, relates to a repair and reinforcement method for concrete structures, and to an anisotropic textile employed in this method. The present invention provides a method which permits execution even in low temperature conditions, and which moreover exhibits superior repair and reinforcement effects in a short period of time; during the impregnation of a resin into a sheet material comprising reinforcement fibers and the curing of this resin to form a fiber-reinforced resin layer which is used in the repair and reinforcement of preexisting structures, a reactive mixture having a gelling period of 15 minutes or more at a temperature of 20&deg; C. and which polymerizes even at 5&deg; C. and is curable within 6 hours, and which has as chief components thereof a monomer containing vinyl groups and a reactive oligomer having vinyl groups and/or a thermoplastic polymer, is employed as the resin. Furthermore, the present invention provides an anisotropic textile for use in the repair and reinforcement of preexisting structures.
