限界があった。2. Description of the Related Art In order to improve the toughness of an existing reinforced concrete column, a reinforcing material such as a steel plate or a reinforced carbon fiber sheet is wound around the surface of the column to integrate it with the existing column, thereby bending and shaping the column. A method of improving the deformation performance of a column subjected to a directional force (compression force) and improving the toughness has been invented. The method is based on the principle that by restraining the volume expansion of concrete that occurs when an external force acts on the column and the shaft deforms, a restraint stress is generated in the column concrete and the deformability of the concrete column in the axial direction is improved. ing.
Comparing the restraining effect of the steel sheet and the reinforcing fiber sheet, generally, the former has a large specific gravity of the material used and a small weight specific strength, but has a large elongation limit of the reinforcing material. On the other hand, in the latter, the specific gravity of the used material is small and the weight specific strength is large, but its elongation limit is small. That is, in the latter case, since the deformation (elongation) limit of the fiber sheet used for reinforcement is small, the effect of improving the column toughness is limited.

An outer peripheral surface of the pillar is subjected to a base treatment, an epoxy resin adhesive 6 is applied to the surface thereof, and a carbon fiber sheet 7 is wound thereon. The sheet solidification layer 9 is formed and is firmly integrated with the concrete column 5.

きなかった。As described above, a conventional fiber-reinforced column 1
When a bending and an axial force (compression force) act on a, volume expansion occurs in the concrete of the column, elongation of the fiber sheet wound in the width direction of the column occurs, and at the same time, constraint stress occurs in the concrete, As a result, it is clear from the example of the experimental results in FIG. 5 that the toughness of the column is improved to some extent compared to that of the column without reinforcement. However, the conventional fiber-reinforced column 1a having no insulating layer has an axial strain of 4000 to 4000.
After reaching 6000 με (× 10 −6 ), the proof stress (axial stress) of the column sharply decreases, and the fiber sheet integrated with the column undergoes stress concentration due to expansion of the concrete and breaks. This is because the stress concentration is more remarkable when a highly elastic fiber sheet is used. Specifically, as shown in FIG. 6, the elongation strain in the width direction of the fiber sheet on the side surface of the conventional fiber-reinforced square pillar has a center (o) of the side surface.
Is significantly larger than both corners (a, b), and the fiber sheet breaks. It is also shown that the face-to-face difference is similarly large. That is, since the fiber sheet integrated with the pillar by the adhesive cannot follow the axial deformation of the concrete, the elongation limit is small, and the effect of improving the toughness cannot be expected much.

い。FIG. 3 shows an example in which the fiber reinforcement of the present invention is applied to a column of an existing RC building. When an axial force (compression force) is applied to the fiber-reinforced column 1, volume expansion occurs in the concrete of the column, and a restraining stress is applied to the concrete column 5 by the carbon fiber sheet 7 wound in the width direction of the column. As a result, a tensile force T in the direction of the arrow shown in FIG.
The epoxy resin adhesive 6 is further applied to the outer periphery of the insulating layer 2 on which the elastic adhesive 4 is applied to the pillar and the insulating film 3 is attached, and the carbon fiber sheet 7 is attached and wound. Is stretched by the tensile force T to generate strain, but since the insulating layer 2 is flexible, it can follow axial deformation due to the expansion of the concrete of the column, and can be quickly carbonized as in the conventional case where the insulating layer 2 is not provided. The fiber sheet 7 does not break.

の柱においても全く同様に適用できる方法である。That is, as shown in FIG. 5, when the fiber-reinforced column 1 provided with the insulating layer 2 receives an axial force,
The axial strain of the column is about 10,300-16,000 με (×
10 −6 ), and the axial strain of the column is about three times as large as that of the conventional column 1 a reinforced with fibers without the insulating layer, and the effect of improving the toughness of the column is remarkable. Also, as shown in FIG.
Although the elongation strain of the carbon fiber sheet 7 in the column width direction is relatively slightly larger than that in the case where the insulating layer is not provided, the elongation strain of the carbon fiber sheet in the width direction on the side surface of the square cross-section column is determined by the center of the side surface (o ) And both corners (a, b) are small.
It is also shown that the face-to-face difference is similarly small. That is, by providing the insulating layer 2, the buffering function works to make the strain distribution of the carbon fiber sheet 7 uniform and the stress concentration does not occur in the fiber sheet. The reinforcing method described above is suitable for an existing column, but is not limited to an existing column, and is a method that can be applied to a newly-constructed column in the same manner.

As a result, the axial deformation of RC columns is extremely limited. Thus, the toughness can be greatly improved. 2) According to the present invention, the insulating layer is made of an elastic adhesive having flexibility and flexibility capable of following the volume expansion of the column during the action of a compressive force, so that the toughness of the column is reliably improved. , And can be greatly expected.
