PURPOSE:To reinforce at site with good workability by the reinforcement of bridge, elevated road or the like by a constitution wherein the sheet concerned consists of various sheet, onto which adhesive layer is provided, and reinforcing fibers, which are unidirectionally arranged and bonded through adhesive layer on the carrier sheet. CONSTITUTION:After adhesive layer 3 is provided on carrier sheet 2 with an adhesive coating roll 7, the sheet 2 is fed in a pressurizing section 8. At the same time, the fiber bundle 4A of reinforcing fiber 4 and releasing paper 9 are fed in the pressurizing section 8 so as to unidirectionally arrange the fiber bundle to the adhesive layer 3 on the sheet 2 and, after that, pile up the releasing paper 9 on the fiber bundle. The fiber bundle 4A is squeezed by being pressed with pressure rollers 8a and 8b band supporting plate so as to bond the reinforcing fiber 4 through the adhesive layer 3 to the sheet 2. After that, the releasing paper 9 is reeled up. When necessary, covering film 13 is covered on the reinforcing fiber 4 on the sheet 2 in order to obtain unidirectionally reinforced fiber sheet 1. |
