摘要： PROBLEM TO BE SOLVED: To provide a reinforcing fiber woven fabric permitting the simple detection of the lamination state of a substrate after molded into an FRP, and to provide a method for detecting the arrangement direction and lamination number of reinforcing fibers in a substrate, after a concrete structure is repaired or reinforced with an FRP plate. SOLUTION: This reinforcing fiber woven fabric satisfies the following requirements (A) to (C). (A) Lateral auxiliary yarn groups are placed on both the sides of a reinforcing multi-filament yarn sheet obtained by arranging reinforcing multi-filament yarns not having such a curve as concentrating stresses into a sheet-like shape in one direction and in parallel to each other, and the lateral auxiliary yarn groups form a woven tissue together with longitudinal auxiliary yarn groups parallel to the arranged reinforcing multi-filament yarns to integrally hold the yarn groups. (B) The adjacent reinforcing multi-filament yarns have spaces of 0.3-2 mm therebetween. (C) Metal wires are inserted.

摘要： PROBLEM TO BE SOLVED: To solve the problems that workability in underlaying an optical fiber cable in a concrete structure is difficult and that the underlaying in the surface of concrete damages appearance by cutting the surface of the concrete structure, etc. SOLUTION: In the sheet-shaped distortion sensor for verifying the progress of damage in the concrete structure, one end of a mesh-shaped or folded optical fiber cable is drawn out, arranged, and fixed onto a sheet-shaped material. By gluing the sheet-shape distortion sensor to the surface of the concrete structure by an adhesive and measuring distortion through the use of the one end of the optical fiber cable drawn out from between the sheet-shaped material, the progress of damage is verified in the method for verifying the progress of damage in the concrete structure.

摘要： PROBLEM TO BE SOLVED: To prevent the coming-off and deformation of an adhesive while or after a cored laminated fiber-reinforced plastic sample is pushed in a drill through a cored hole at the time of cutting-off the sample by using a coring blade attached to the front end of the drill. SOLUTION: A cylindrical drill section 2 in which a pressure bar spring 5 both ends of which are respectively attached to a spring pressure adjusting screw 5 and a presser bar 9 is set so that the spring pressure of the spring 5 may be adjusted by means of the screw 7 is connected to a cylindrical drill section 3 provided with a cylindrical coring blade 12 at its front end by engaging the thread of the section 2 with the thread of the section 2 and the presser bar 9 attached to the spring 5 is inserted into the coring hole 17 of the blade 12. Since the laminated sample of a fiber-reinforced plastic 23 is pressed by the presser bar 9, the occurrence of such a case that the sample 24 is pushed in the drill section 3 or an adhesive comes off or is deformed can be eliminated when the laminated sample 24 is collected.

摘要： PROBLEM TO BE SOLVED: To select and connect a pair of lead wires to a distortion-measuring apparatus thereby forming an electric circuit at an optional point, by connecting a plurality of insulated coated lead wires via a suitable interval to a long insulated coated resistance wire. SOLUTION: A distortion sensor 1 has lead wires 3 connected via a suitable interval to a thin long resistance wire 2, and is coated with a coating 4. The resistance wire 2 used a thin wire so that it can be positioned between a concrete structure and a reinforcing layer or between reinforcing layers. The connection of the lead wires 3 to the resistance wire 2 is made by soldering or spot welding so as not to increase an outer diameter of the distortion sensor 1. The resistance wire 2 is formed of a conductive material that can act integrally with a place where the wire is placed, e.g. an advance wire of an alloy of nickel, cobalt, copper and manganese.

摘要： PROBLEM TO BE SOLVED: To solve the problems such that it is difficult for a concrete structure in a workability to lay an optical fiber cable and that when laying the cable on a surface of the structure, beauties of the structure are damaged due to cutting the surface of the structure. SOLUTION: In a facial distortion sensor for verification of damage proceeding of concrete structure, single or more than one optical fiber cable is fixed with pulling one end of the cable to be inserted between a gap of sheet shaped objects allowing penetration of an adhesive. In a method for verification of damage proceeding of concrete structure, the sensor is bonded on the surface of the structure by using the adhesive to verify the damage proceeding with measuring distortion by using one end of the cable pulled from the gap of the objects.
