BACKGROUND OF THE INVENTION Beams, floor slabs, and other various structures of concrete structures deteriorate over many years of use due to corrosion, racking, etc., and their strength decreases due to the effects of bending stress, etc., resulting in the need for reinforcement.

作業効率が悪い。Conventionally, reinforcement of such structures, for example, when the floor slab of a concrete structure (concrete slab) has decreased in strength due to deterioration, has been achieved by using iron plates as the reinforcing material and attaching the iron plates with anchor bolts, etc. The method used was to fix it at reinforced points. In addition, the side plates of steel plate tanks are generally reinforced by attaching iron plates by welding or the like. However, if steel plates are used as the reinforcing material, the weight of the reinforcing material will be large, making reinforcing work on large areas difficult from the perspective of handling the reinforcing material 4, and depending on the reinforcement location, additional reinforcing material may not be added. The task itself is often impossible or extremely difficult;
Work efficiency is poor.

に押圧して、貼り付けることにより行なわれる。For example, reinforcement of a concrete slab with a fiber-reinforced plastic plate is performed by applying adhesive 3 directly or via a primer to the surface 2 of the concrete slab l at the location to be reinforced, and then applying the fiber-reinforced plastic plate to the surface 2 of the concrete slab l, as shown in FIG. Place plate 4 onto surface 2 of concrete slab l from adhesive 3.
This is done by pressing and pasting.

When air is trapped between the fiber-reinforced plastic plate 4 and the gap 5 is created, the fiber-reinforced plastic plate 4
In order to reduce the reinforcing effect caused by the adhesive 3 and the fiber-reinforced plastic plate 4, the fiber-reinforced plastic plate 4 is attached in such a way that air is not trapped between the adhesive 3 and the fiber-reinforced plastic plate 4 as much as possible. However, since the m-fiber reinforced plastic plate 4 with a reasonably large area is pasted,
It is difficult to prevent air from being trapped between the adhesive 3 and the fiber-reinforced plastic plate 4, and the trapped air often creates a void 5. The generation of voids 5 due to trapped air becomes more significant as the size of the fiber-reinforced plastic plate 4 used increases. In addition, if the surface 2 of the concrete slab 1 has unevenness, adhesive 3 may be applied thickly to the surface 2 of the concrete slab 1 to eliminate the effect of unevenness, but even if the adhesive 3 is thick, the adhesive 3 and the fibers Similarly, it is difficult to prevent air from being trapped between the reinforced plastic plate 4 and the trapped air creates a void 5.

Even if air is trapped between the fiber-reinforced plastic plate and the fiber-reinforced plastic plate, the trapped air can be easily prevented from remaining, and excess adhesive can be easily discharged without creating any voids. The fiber-reinforced plastic plate is pasted on the structure, and the reinforcement effect of the fiber-reinforced plastic plate is fully exhibited, so that the structure can be reinforced. An object of the present invention is to provide a fiber-reinforced plastic plate for reinforcing structures and a method for manufacturing the same.

み込まれに<〈、また余分な接着剤も残らない。Next, one end side of the carbon fiber reinforced plastic plate 6 is pressed against the surface 2 of the concrete slab l from above the adhesive 3, and then the carbon fiber reinforced plastic plate 6 is sequentially pressed to the other end side, and the adhesive 3 is pressed against the surface 2 of the concrete slab l. A carbon fiber reinforced plastic board 6 is attached to the surface 2 of a concrete slab 1 in such a way that air is not trapped between the carbon fiber reinforced plastic board 6 and the carbon fiber reinforced plastic board 6 as much as possible. This carbon fiber reinforced plastic plate 6 has a through hole 8 penetrating in its thickness direction, and air between the adhesive 3 and the carbon fiber reinforced plastic plate 6 is discharged to the outside through the through hole 8. Since air is trapped between the adhesive 3 and the carbon fiber reinforced plastic plate 6, no excess adhesive remains.

The suppressing means 11 includes a push bar 12 mounted at a relatively small pitch in a position that does not block the through hole 8, a thicker and more rigid push bar 13 that supports the push bar 12 in a right angle direction, and a push bar 13 that supports the push bar 12 at a right angle. It is preferable that the support 14 is made up of a normal support 14 which is adjustable in the length direction and supports and presses the support 14 at a predetermined pressure. Note that the suppressing means 11 can also be configured using an air bag or the like.

ることができる。As described above, the carbon fiber reinforced plastic plate 6 is pressed by the pressing means 11. Then, since the carbon fiber reinforced plastic plate 6 has a through hole 8 penetrating in the thickness direction, air trapped between the adhesive 3 and the carbon fiber reinforced plastic plate 6 or excess adhesive can be removed. The agent is inserted through the through hole 8.
It passes through and is discharged to the outside from between the pressed square pieces 12. Therefore, there is no residual air trapped between the adhesive 3 and the carbon fiber reinforced plastic plate 6, and no voids are created due to the trapped air. A carbon fiber-reinforced plastic plate 6 can be attached to the surface 2 of a concrete slab 1 without leaving any residue. Therefore, the concrete slab 1 can be reinforced by fully exerting the reinforcing effect of the carbon fiber reinforced plastic plate 6.

充填することによって、空気を排出することができる。As explained above, the fiber-reinforced plastic plate according to the present invention has a through hole that penetrates in the thickness direction, so it can be attached to the surface of the structure where it is to be reinforced using an adhesive. Even if air is trapped between the adhesive and the #a fiber-reinforced plastic plate when pasted, the air can be exhausted to the outside through the through hole, and the air can be completely removed. Even if it is not, inject the adhesive through the through hole,

Furthermore, excess adhesive can be discharged and adhesive can be prevented from accumulating locally, and as a result, the fiber-reinforced plastic plate can fully exhibit its reinforcing effect and the structure can be reinforced. In addition, a fiber-reinforced plastic plate having through holes without cutting the reinforcing fibers does not reduce the strength of the reinforcing fibers, so a great reinforcing effect can be obtained and the range of use is wide.
