摘要： PURPOSE: To facilitate operations and to greatly enhance earthquake resistance and design load by bonding first high strength lint axially on an existing structure, and winding second high strength lint transversely over the first high strength lint. CONSTITUTION: A plurality of sheets of first high strength lint 2, each of which is made from carbon fiber reinforced plastics or the like into a flat shape, that is, a tape shape, are bonded axially on the outer peripheral surface of an existing chimney 1 made of reinforced concrete. The surface of the high strength lint 2 is covered with a synthetic resin film such as a polyester film of edging material and second high strength lint strands 3 are further wound thereon. The first high strength lint 2 inhibits initial cracking and enhances flexural strength and the second high strength lint 3 increases the axial force of the existing structure to enhance earthquake resistance and design load.

摘要： PURPOSE:To obtain a foundation with fortified head at low cost by a method in which carbon fibers are wound around a driven pile from the embedded portion to the pile head, and a structure is constructed on the pile head. CONSTITUTION:The head of a hollow reinforced pile 2 being driven is crushed to expose main reinforcing bar 3, and long carbon fibers 4 impregnated with a resin are wound around the exposed portion of the pile 2 from the natural ground 1 and clamped. Soil 5 is embedded on the pile head portion, and a footing 6 is constructed on the top of the pile 2. The foundation with fortified pile head can thus be constructed at low cost.

摘要： PURPOSE:To efficiently reinforce a structure by sticking a plate bode impregnated with resin into reinforcing fibers and the like on the surface of a structure element to be reinforced of a structure, coating a solution containing a hardening agent and a solvent, and drying and hardening it. CONSTITUTION:Resin such as phenol resin and epoxy resin serving as a matrix is impregnated into a uniaxial orientation object, a woven fabric, and a nonwoven fabric of fibers such as carbon fibers and glass fibers used as reinforcing fibers to form a plate shape with the thickness of about 0.1-2mm. This plate body is stuck on the surface of a structure element to be reinforced of a structure, a solution containing a hardening agent such as hexamethylenetetramine and aliphatic diamine and a solvent such as ethanol is coated, and it is dried and hardened by forced hot-air drying and the like. The solution is hardened in a short time with good workability regardless of the change of temperature, and the structure can be efficiently reinforced.

摘要： PURPOSE:To harden a fiber-reinforced composite material in a short time with good workability regardless of the change of the environmental conditions, e.g. temperature in particular, and concurrently attain the storage stability of the fiber-reinforced composite material and the short-time hardening at the site. CONSTITUTION:A fiber-reinforced composite material impregnated with a resin composition material containing thermosetting resin and practically containing no hardening agent of resin into fibers is stuck on the surface of a structure element to be reinforced of a structure. A solution containing the hardening agent of the thermosetting resin and a solvent is coated on the fiber-reinforced composite material, and it is dried and hardened.

摘要： PURPOSE:To reduce the construction cost by arranging reinforcing members in the peripheral direction, superposed to the outside of a high strength long reinforcing members in the longitudinal direction, on a step difference part installed on the outside surface of a concrete body, and curving the reinforcing member in the longitudinal direction and engaging the reinforcing members with the step difference part. CONSTITUTION:High strength long fiber reinforcing members 4 are wound and fixed in the peripheral direction and a step difference part 1 is formed on the edge part surface of an already existing RC body 1. High strength long fiber reinforcing members 2 are attached on the reinforcing member 4, adjusting orientation in the longitudinal direction of the body 10. Then, high strength long fiber reinforcing members 3 are wound and fixed at the upper and lower places contiguously to the step difference part 1 on the reinforcing member 2, adjusting orientation in the peripheral direction.

摘要： PURPOSE:To accelerate hardening of a thermosetting resin so as to shorten the time required for curing the resin and secure construction work while it is cold by sticking onto the surface of a concrete structural member a reinforcing fiber material impregnated with the thermosetting resin, and providing a heating means opposite to the surface of the concrete structural member, and heating the resin. CONSTITUTION:A reinforcing fiber material 2 such as carbon fiber, etc., is stuck to the whole of the outer peripheral surface 1a of a concrete pole 1 and is impregnated with a normal temperature setting type resin such as epoxy resin etc. A cloth-shaped body 2 serving as a heating means such as an electric blanket is disposed around the concrete pole 1 and opposite to the surface 1a of the pole 1. A tubular heat insulating member 4 is provided outside the cloth-shaped body 3 in such a manner as surrounding the whole of the cloth-shaped body 3 so that the cloth-shaped body 3 is shut out from the outside. Thereby the temperature around the fiber material is relatively heightened and hardening of the resin is accelerated so as to shorten the period of time required for curing the resin and secure construction work for the concrete pole in cold districts and while it is cold, thus facilitating construction work.
