A reinforced structure disclosed in JP-A-9-235893 is known. This reinforced structure is formed by laminating a reinforcing fiber and a room-temperature-curable resin on the surface of a concrete structure, curing the resin, and then applying a flame-retardant paint. , Aramid fibers and the like are used.

多くの問題が残されていた。[0003] However, since this reinforcing method is based on the premise that bonding of reinforcing fibers is performed on site, when reinforcing the upper floor slab or wall surface of a tunnel or subway,
Since the work must be completed in the time from the last train to the first generator, the actual work time is extremely short, such as 1 to 2 hours, and there is a disadvantage that the construction period is long. Further, when the reinforcing fibers are bonded to the upper floor slab or the ceiling, the reinforcing fibers may be bent or dropped during the adhesive curing due to the weight of the adhesive or the sheet. For this reason, so-called safety temporary work is required, in which a fall prevention tool such as a net is temporarily fixed to the wall of the reinforcing portion using an anchor or the like on the outside of the bonded reinforcing fiber sheet and removed after curing is completed. The enforcement time was also long. In addition, in order to ensure the fire resistance function, it is necessary to attach and remove the curing net even when applying fire resistant mortar to the outside of the bonded reinforcing fiber, and many problems remain in the on-site reinforcement work.

ことができる。A refractory plate 1 having a sheet-like reinforcing fiber 2 formed by impregnating and fixing a thermosetting resin 3 in advance is fixed on the surface (see FIG. 1). In order to increase the adhesive strength between the thermosetting resin 3 and the refractory plate 1, it is desirable to provide a primer layer 4 between them. By applying the adhesive 5 to the reinforcing portion 10 and pressing the refractory plate 1 with the fiber layer inside, the reinforcing fiber layer 2 can be bonded to the reinforcing portion 10. In addition, in order to enhance the adhesive effect of the adhesive 5, it is preferable to perform the same primer treatment as the above and the fireproof plate. Since the anchoring hole 6 is formed in the reinforcing portion, the refractory plate 1 is fixed to the reinforcing portion 1 using the anchor bolt 7.
When it is fixed to 0, the refractory plate 1 itself prevents the reinforcing fiber layer from bending and falling, and can cure the adhesive as it is. Since the adhesive fiber of the reinforcing fiber 2 is cured by the fire-resistant plate 1, the fire-resistant function can be provided as it is after the adhesive is cured, and a step of separately applying a fire-resistant paint or mortar is not required (see FIG. 2). When performing the construction, the effect of the primer and the adhesive can be sufficiently exhibited by washing the reinforcing portion using high-pressure water or the like.
If the surface of the reinforcing portion 10 has irregularities, the surface of the refractory plate 1 can be prevented from being inclined if it is smoothed as much as possible by grinding with a sander or filling a putty.

とができる。In this method, the refractory plate 1 having the reinforcing fibers 3 impregnated and fixed with the thermosetting resin 3 fixed on the surface using the anchor holes 6 is first fixed to the reinforcing portion 10 with the anchor bolts 7. At this time, the thickness of the gap into which the adhesive is to be injected can be adjusted by interposing the spacer 15 between the two. Next, a seal 8 is provided between the periphery of the refractory plate 1 and the reinforcing portion 10, and a pipe 16 for injecting an adhesive is fixed. If a gap is formed between the bolt 7 and the refractory plate 1, a seal 9 may be applied to this portion as well. After the adhesive 17 is injected into the gap using the pipe 16, the pipe 16 is closed and cured as it is (see FIG. 3). When only the reinforcing fiber 2 impregnated and fixed with the thermosetting resin 3 is bonded to the reinforcing portion by the injection method, it is necessary to press the form from outside to prevent the reinforcing fiber layer from bending. However, in the above technical means, since the fireproof plate 1 itself functions as a mold, a step of removing the mold is not required, and the fireproof plate 1 can have the fireproof function as it is after the adhesive is cured.

Urethane-based, polyester-based, and acrylic-based ones can be suitably used. In the first technical means, a thixotropic adhesive can be suitably used. By slightly raising the central portion of the applied adhesive layer or the like, it is possible to prevent air from being mixed into the adhesive when the fireproof plate 1 is pressed. In the second technical means, a liquid adhesive will be used. As these adhesives, it is desirable to use epoxy-based, urethane-based, polyester-based, and acrylic-based thermosetting adhesives. The fire-resistant plate is preferably lightweight because it is carried into the site, and a calcium silicate-based or cement-based inorganic lightweight fire-resistant plate can be suitably used.

うことができる（請求項４参照）。DESCRIPTION OF THE PREFERRED EMBODIMENTS In a reinforcing method according to the present invention, a refractory plate 1 is formed so as to correspond to one or more divided lengths of a reinforcing portion, and a reinforcing fiber 2 is formed by aligning the fiber direction with the length direction. And an anchor through-hole 11 is formed. When the fire-resistant plate of this form is used, most work is performed at a place other than the site, and at the site, only the reinforcing fibers 2 fixed to the fire-resistant plate 1 are bonded to the reinforcing portion 10, so that workability is extremely high. can do. The reinforcing fiber 2 is in the form of a so-called FRP in which the thermosetting resin layer 3 is impregnated and fixed. However, in this reinforcing method, the reinforcing function of the reinforcing fiber and the fireproof function of the fireproof plate are independent functions. The reinforcing fiber board in the FRP state may be formed first, and this may be fixed to the fireproof board with an adhesive or a double-sided adhesive tape. In the fire-resistant plate of this embodiment, it is possible to easily change the size and the like of the fire-resistant plate 1 by cutting unnecessary portions on the site or forming cutouts (see claim 4).

とができる（図４、請求項５参照）。When the anchor hole 11 is formed after the reinforcing fiber layer 2 is formed on the entire surface of the refractory plate 1, the fiber is cut at that portion, and the cut fiber cannot be expected to have a reinforcing effect. For this reason, the fire-resistant plate 1 is provided with tape-shaped vacant spaces 18, 18 having at least the same width as the diameters thereof, which pass through the anchor holes 11, 11 in the longitudinal direction, and the reinforcing fibers
The reinforcing fibers can be used effectively by adhering (see FIG. 4 and claim 5).

いても活用することができる。When the refractory plate 1 is used in which the reinforcing fibers 2 which are not impregnated and fixed with the thermosetting resin 3 are used at both ends 12 of the fiber, unnecessary end portions of the refractory plate at the site can be easily cut off. Can be. Fireproof plate 1 on reinforcement 10
The protruding end 12 of the reinforcing fiber may be directly adhered to the reinforcing portion 10 using an adhesive, or may be cut off if unnecessary (see claim 6). The refractory plate of this embodiment can be used even when the reinforcing fiber sheet 13 is used by bending the reinforcing fiber sheet 13 at a corner when reinforcing a pillar.

It is necessary to strengthen the reinforcement by the fiber in the reinforcement part. In this case, it is desirable that the joint between the refractory plates 1 and 1 generated by the refilling is filled with mortar 20 to secure the refractory function. As shown in FIG. 5, when the end of the refractory plate 1 is cut out in a tapered shape so that the outer joint width becomes small, the cavity becomes an inverted triangular shape, and the dripping of the filled mortar 20 is prevented. Most of the outer surface of the mortar 20
