Abstract

PROBLEM TO BE SOLVED: To compromise between an increase in strength and enhancement of toughness when applying a fiber reinforced sheet to the outer periphery of an existing reinforced concrete column. SOLUTION: A corner part in which concrete is effectively subjected to a restraint pressure (stress) from a fiber reinforced sheet 2 therearound in association with volumetric expansion of concrete, in particular, a part having a length, at each side of a rectangular cross-section, of about one-fourth of the width of the side, is a bonding part composed of the concrete and the fiber reinforced sheet 2 which are solidified and integrally incorporated together in order to ensure a sufficient strength. A part having a length, at each side of the rectangular cross-section, of about a half of the remaining of the width of the side, is inserted therein with an insulating layer for relieving stress, between the concrete and the fiber reinforced sheet 2, so as to make elongation of the fiber reinforced sheet 2 uniform in the widthwise center part where large elongation easily occurs in order to prevent the strain from exceeding a crital deformation, thereby it is possible to enhance the toughness.

2. Description of the Related Art For example, in order to increase the strength and toughness of an existing reinforced concrete column, a reinforcing fiber sheet is wound in a lateral direction along the outer periphery of the surface to receive a compressive force among the concrete column. Methods have been implemented to improve the strength and toughness of the parts. This is to restrain the volume expansion of the concrete caused when an external force acts on the column member and deform it with the reinforcing fiber sheet, thereby generating a restraining stress in the column concrete and increasing the compressive strength in the concrete material axial direction. And the principle of improving the deformation performance.

[0003] Such a conventional method of attaching a reinforcing fiber sheet to a reinforced concrete column is roughly classified into two types.
One is to bond the entire length of the reinforcing fiber sheet wound in the lateral direction along the outer periphery of the reinforced concrete column to the outer periphery of the reinforced concrete column. More specifically, placing a reinforcing fiber sheet in the area that requires reinforcement,
The whole is solidified and integrated with the part to be reinforced. Hereinafter, this attaching method is also referred to as Conventional Example 1.

The other is to make the entire reinforcing fiber sheet insulated. Note that, when the reinforcing fiber sheet is insulated, the elastic adhesive layer having a buffer function between the concrete surface and the solidified layer of the fiber sheet, for example, does not cause stress concentration when attaching the reinforcing fiber sheet. The provision of an insulating layer as described above. Hereinafter, this attaching method is also referred to as Conventional Example 2.

First, in the method of pasting the reinforcing fiber sheet of the conventional example 1, since the deformation limit of the reinforcing material such as the reinforcing fiber sheet used for reinforcing is originally small, the effect of improving the toughness of the reinforced concrete column is limited. is there. That is, when a force acts on each member after reinforcement, volume expansion occurs in the concrete of the column, and the fiber sheet stretched along the outer periphery of the column generates elongation, and at the same time, constraint stress occurs in the concrete,
As a result, the strength of the column member increases and the toughness is improved, but the elongation strain generated in the fiber sheet at this time is not uniform, and tends to increase particularly near the crack occurrence position of the concrete, As a result, this part breaks and reaches the deformation limit. That is, although a simple increase in strength can be achieved, a significant improvement in toughness cannot be achieved.

On the other hand, in the method of pasting the reinforcing fiber sheet according to the conventional example 2, the insulating layer having a buffer function of stress concentration is interposed between the reinforcing fiber sheet and the concrete, so that the reinforcing fiber sheet is provided. As a result, it is possible to average the elongation of the reinforcing fiber sheet and increase the deformation limit of concrete. However, since the insulating layer absorbs the volume expansion of the concrete itself, as a result, the binding force of the reinforcing fiber sheet is weakened, and no useful binding stress is generated. In other words, it is possible to achieve a great improvement in toughness, but it is not possible to greatly increase the strength of concrete columns.

In this embodiment, as shown in FIG. 2, only the corners of the reinforced concrete column 1 of the reinforced concrete columns 1 are reinforced among the reinforcing fiber sheets 2 attached laterally along the outer periphery of the reinforced concrete column 1. The other parts are insulated. More specifically, assuming that the length of one side of the cross section of the reinforced concrete column 1 is D, about 1/4 of one side from both corners of each side, that is, about D / 4, is an adhesive portion, and the remaining D Approximately / 2 is an insulating portion.

FIG. 3 shows a difference in the procedure for applying the adhesive portion and the insulating portion. The construction procedure itself of each of these parts is the same as the conventional one, but the feature of the present embodiment lies in that both are used in combination. To briefly explain the procedure for both, the adhesive portion is first coated with a primer treatment agent called primer 3 on the surface of concrete 1 ′, and then the concave portion on the surface of concrete 1 ′ is filled with resin putty 4.
Next, after the undercoating of the resin 5, the reinforcing fiber sheet 2 is wound, and further the overcoating of the resin 6 is performed. The primer 3 is also hardened, and the primer 3 is also hardened and integrated with the undercoat resin 5, so that the surface of the concrete 1 'and the reinforcing fiber sheet 2 are integrated to form a so-called bonded state. On one insulating part, first, the concave portion on the surface of the concrete 1 'is filled with the resin putty 4, and then the insulating layer 7 such as an elastic adhesive is formed.
Then, the undercoating of the resin 5, the winding of the reinforcing fiber sheet 2, and the overcoating of the resin 6 are performed. Even in this insulating part, from the top coating resin 6 to the under coating resin 5 is solidified integrally, an insulating layer 7 made of an elastic adhesive or the like is solidified inside.
Becomes a large deformable element. As a result, even if the concrete 1 ′ is deformed, the deformation is absorbed by the insulating layer 7, and the large deformation does not reach the reinforcing fiber sheet 2.
In other words, the elongation strain of the reinforcing fiber sheet 2 can be made uniform.

Next, the operation of the method for attaching a reinforcing fiber sheet to a reinforced concrete column according to the present embodiment will be described.
Here, FIG. 4 shows the restraining pressure (stress) in the concrete cross section subjected to lateral pressure by the lateral restraint material, that is, the reinforcing fiber sheet.
FIG. 5a shows the conventional method 1, that is, the method of bonding the entire reinforcing fiber sheet 2 to the reinforced concrete column 1, and FIG. 1 shows the construction state of the method of insulating a steel sheet.

First, when a concrete member having a rectangular cross section expands in volume, the constraint pressure (stress) distribution generated by the surrounding restraining material, that is, the reinforcing fiber sheet is as shown in FIG.
In the figure, the confined pressure (stress) is higher at a darker portion. As is apparent from the figure, since the reinforcing fiber sheet resists the expansion of the concrete through the corners of the concrete cross section, the insulating layer such as the elastic adhesive is provided at the corners as in the conventional method 2. When it is provided, the expansion of the concrete is absorbed, and the restraining pressure (stress) is reduced. Therefore, in the present embodiment, the reinforcing fiber sheet and the concrete are solidified and integrated by using the corners of the rectangular cross section of the concrete rectangle, more specifically, about one-fourth of one side, D / 4, from both corners as an adhesive portion. This ensures the required strength.

On the other hand, in the conventional method 1, most of the cracks generated on the concrete surface are distributed almost at the center of one side of the rectangular cross section concrete. Therefore, when the concrete expands, the elongation strain generated in the reinforcing fiber sheet is not uniform, and the center of one side of the rectangular cross-section concrete is large and gradually decreases toward the corner.
Therefore, the reinforcing fiber sheet in the portion where the strain is concentrated near the crack reaches the limit of deformation. Therefore, in the present embodiment, one half of one side, D / 2, of a portion other than the adhesive portion, that is, a central portion of each side of the rectangular cross section concrete.
The degree is an insulating portion, and the large elongation strain generated in the center of this one side is absorbed by the insulating layer to make the elongation strain generated in the reinforcing fiber sheet uniform, thereby making it difficult for the reinforcing fiber sheet to exceed the deformation limit. Improve toughness.

As a result, as shown in FIG. 6, in the method of attaching the reinforcing fiber sheet of the present embodiment to an unreinforced reinforced concrete column, the strength (load resistance) of the same degree as that of the conventional method 1 is increased. In addition, improvement in toughness (deformation resistance) at the same level as in Conventional Method 2 can be achieved.
