能な閉空間とするのにも役立っている。According to this method, the reinforcing work can be performed using a reinforcing plate having a small area corresponding to the interval between a large number of arranged anchors, so that the weight per reinforcing plate can be reduced. The structure can be reinforced by light work. Further, since a large number of holes are formed in the reinforcing plate, it is possible to further reduce the weight of the reinforcing plate that often uses a steel plate from the viewpoint of securing strength. As the reinforcing plate, a punching metal can be used, and when an expanded metal or a steel plate in the form of a mesh is used, the effect of reducing the weight becomes greater. If further weight reduction of the reinforcing plate is desired, a plate made of FRP can be used. In this reinforcing method, an auxiliary plate is laminated on the reinforcing plate. Therefore, even if a steel plate is used as a reinforcing plate, the reinforcing plate is not exposed,
Rust prevention treatment can be omitted. From this viewpoint, it is preferable that the auxiliary plate is formed of a material other than metal. In addition, pressure bonding and lamination of the auxiliary plate to the reinforcing plate is performed after a putty-like adhesive is applied to the auxiliary plate in advance. There are many holes in the reinforcing plate, so there is no air pocket between the reinforcing plate and the auxiliary plate, and putty-like adhesive passes through the holes formed in the reinforcing plate to the back side of the teaching aid. Since the adhesive becomes anchor-like by solidifying as it goes around, the connection between the reinforcing plate and the auxiliary plate can be made strong. And, in this method, by filling a filler formed in the space formed between the reinforcing plate and the surface to be reinforced by the anchor functioning as a spacer, the surface to be reinforced, the anchor, the reinforcing plate and the auxiliary plate are integrated. In addition, the reinforcement strength can be further enhanced. The auxiliary plate also serves to make the space formed between the surface to be reinforced and the reinforcing plate a closed space in which filler can be filled.

からである。[0007] It is preferable that the auxiliary plate is pressure-bonded to the reinforcing plate so as to straddle the adjacent reinforcing plate. By connecting the adjacent reinforcing plates via the auxiliary plate, the reinforcing strength obtained by the reinforcing method of the present invention is further improved.

This pipe can be used as a passage for releasing air from the space when the auxiliary plate is laminated on the reinforcing plate, and as a passage for injecting a filler into the space after the auxiliary plate is laminated. Since it can be used, further efficiency of work can be expected.
It is more preferable to provide a plurality of pipes, because one pipe can be used for injecting the filler and the other pipe can be used for air release at that time.

い。In order to carry out the method for reinforcing a structure according to the present invention, first, dirt such as latencies adhered to the surface 1 to be reinforced is removed. Next, the anchor 2 is attached to the surface 1 to be reinforced. The anchor 2 used in this embodiment includes a washer 3 and a bolt 4
The washer 3 is attached to the surface 1 to be reinforced by bonding the washer 3 to the surface 1 to be reinforced. This state is shown in FIG. In this embodiment, as shown in FIG. 2, the anchor 2 is attached to the surface 1 to be reinforced in a grid pattern. The anchor 2 is not limited to the one shown in the figure. For example, a concrete anchor may be used in which the surface to be reinforced 1 is bored and driven in and mechanically fixed.

The upper nut 5 is fixed to the bolt part 4 of FIG. This nut 5
Is for positioning the height position of the reinforcing plate 6 to be described later, and it is necessary to fix the reinforcing plate 6 to horizontal positions. Therefore, when the upper nut 5 is fixed, the water thread 7 is stretched vertically and horizontally between the anchors 2 to perform the work while checking the horizontal. FIG. 1 shows a state in which the upper nut 5 is fixed.
This is shown in (B).

More specifically, the bolt 4 of the anchor 2 is inserted into the fixing hole of the reinforcing plate 6, and the lower nut 9 is squeezed by sandwiching the reinforcing plate 6 with the upper nut 5 already fixed. Each reinforcing plate 6 is fixed to each anchor 2 while being positioned on the same plane. This state is shown in FIG.

Specifically, the auxiliary plate 13 is pressure-bonded to the reinforcing plate 6 so as to cover the entire surface to be reinforced 1 while straddling the adjacent reinforcing plate 6. When the auxiliary plate 13 is pressed against the reinforcing plate 6, the putty adhesive 12 applied to the surface of the auxiliary plate 13 wraps around the back side of the reinforcing plate 6 from the hole 8 provided in the punching metal 6 to form a mushroom-like shape. As a result, the anchor effect is exhibited. This state is shown in FIG.
Note that the auxiliary plate 13 in this embodiment uses a fiber woven fabric that has been subjected to FRP processing in advance.

Although it is sufficient to provide two pipes 11 for the time being, it is preferable to provide a plurality of pipes 11 at four corners of the surface 1 to be reinforced.
The mounting portion of the pipe 11 is shown enlarged in FIG.

I do. At this time, the other pipes function so as to remove the air pushed out from the space. FIG. 1E shows a state in which the filler 14 is filled. As the filler, a resin adhesive or a polymer cement material can be used. Using a polymer cement-based material as a filler is excellent in cost. It is more preferable to mix a vaporizable and diffusible rust preventive material (such as a low molecular organic compound of amines) into the filler because the rust preventive effect of the reinforcing member inside the reinforced surface 1 can be obtained. The distance between the surface 1 to be reinforced and the reinforcing plate 6 is preferably about 1 cm when using a resin-based adhesive as a filler, and about 1 cm to 3 cm when using a polymer cement-based material. Good to do.
