A prepreg type obtained by impregnating a thermosetting resin into a sheet material in which long fiber yarns are arranged (Japanese Patent Application Laid-Open No. 3-221568);
By heat-treating a woven fabric made of a reinforcing fiber constituting one of the woven fabric type, warp and weft and a heat-fusible fiber constituting the other, the intersection of the warp and the weft of the woven fabric is determined by the heat-fusible fiber. There is a reinforcing material such as a so-called one-way cross type (Japanese Patent Application Laid-Open No. 7-243149) which is fixed by heat-sealing ability.

Bending reinforcement, such as stabilizing the bending stress by reinforcing the tensile stress resistance by sticking or the like so that the direction of the fiber of the material matches so as to increase the rigidity of the floor slab, etc. There is a shear reinforcement that wraps around a beam or the like to reinforce the shear resistance.

A stiffener must be attached to the structure.

も必要とする。Therefore, when the above-mentioned flexible sheet-like fiber reinforcing material is used, it is necessary to strictly correct the unevenness of the surface of the structure on which the fiber reinforcing material is adhered. In addition, there is a complicated problem that a skill for attaching the fiber reinforcing material without meandering is required. When the above-mentioned sheet-like fiber reinforcement is used, the fiber reinforcement must be impregnated with a resin before or during construction, and the fiber reinforcement is attached to the surface of the structure. In addition to the application of a resin as an adhesive for attachment, an impregnation step of impregnating the fiber reinforcing material with the resin using a roller, a rubber spatula, or the like is required.

ない。On the other hand, Japanese Unexamined Patent Publication (Kokai) No. 63-35967 discloses a method of reinforcing a structure in which a reinforcing material made of a fiber reinforced resin plate in which a reinforcing fiber is impregnated with a resin in advance is adhered to the surface of the structure. The construction method has been described, and in the method of reinforcing a structure by this construction method, a reinforcing fiber is used in advance by using a fiber-reinforced resin plate that is fixed in a straight line,
The meandering of the fiber accompanying the sticking operation can be avoided, and no resin impregnation step is required before or during the construction.

When sticking to a surface having a three-dimensional shape, such as when sticking, a fiber-reinforced resin plate as a reinforcing material must be formed into a shape along the sticking surface of the structure.

It is conceivable to solve the above problem by performing a reinforcing method of winding a reinforcing fiber tow impregnated with a three-dimensional surface, etc., but the type of reinforcing material for the structure is different, and the reinforcing method is different. The use of two or more types on site increases the types of resins used on site, which not only complicates management but also causes confusion for workers.

Especially those using an acrylic resin as the matrix resin, because the viscosity of the acrylic resin before curing is low, the impregnating property to the reinforcing fibers during molding of the fiber reinforced resin plate is good, and at a low curing temperature. It cures in a short time, if any. For this reason, a target fiber reinforced resin plate can be produced with high efficiency. As the acrylic resin, a mixture of a (meth) acrylic monomer and a (meth) acrylic oligomer and / or a polymer, or a resin containing the mixture as a main component can be used.

If the compounding amount of the reinforcing fiber is less than 200 g / m 2 , when reinforcing the structure with the reinforcing material composed of the fiber reinforced resin plate, it is necessary to laminate the reinforcing material in multiple layers. In addition, the compounding amount of the reinforcing fiber is 1200 g / m 2.
When the ratio exceeds 3, the overall rigidity of the fiber reinforced resin plate as the reinforcing material becomes too high, so that it is difficult to perform the forming process when forming into a three-dimensional shape.
