DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining plate for covering a wall surface of a concrete structure such as a sewage facility and the like, a structure thereof, and a construction method thereof.

These tanks have a sealed structure so that gas generated from sewage and the like contained therein does not leak.

However, there is a problem that concrete on the inner wall surface of the tank is corroded and damaged by generated gas, bacteria in sewage and sewage sludge, and the like.

For this reason, a lining plate made of a synthetic resin such as hard vinyl chloride is applied to the inner wall surface of the tank to cover the inner wall surface of the concrete, thereby protecting the concrete surface.

[0005] Such a lining plate is constructed by using a resin lining plate formed in a strip flat shape and having a large number of rib pieces formed in parallel with each other on one surface. When the lining plate is mounted on the formwork in advance and the concrete is solidified after casting and curing of the concrete, the concrete surface is covered with the lining plate, and a concrete tank that has already been constructed and is causing corrosion Spread this lining plate on the inner wall of the
There is a construction method in which concrete or mortar is filled between the lining plate and the corroded inner wall surface from which the corroded layer has been removed, and the inner wall surface is restored.

[0006]

However, since the above-mentioned conventional lining plate is a colored and opaque plate material, the solidified concrete as the wall surface closely adheres to the lining plate without gaps, that is, between the rib pieces. There is a disadvantage that it is not possible to visually check whether the rib pieces are securely buried in the concrete.

Further, if there is a large gap between the lining plate and the concrete wall, there is a possibility that the lining plate is deformed by the pressure, the joint is broken, and the concrete in the void portion is corroded. is there.

The presence or absence of such a gap is examined by hitting it with a gavel or the like from the surface of the lining plate. However, this is a complicated operation and cannot be easily found. .

In order to solve the above-mentioned problems, the present invention provides a lining plate and a structure and a lining plate capable of easily judging a covering state on a concrete wall, that is, a close contact state between the concrete and the lining plate during lining work. It is an object of the present invention to provide a method for constructing this lining plate.

[0014]

FIG. 1 is a perspective view showing an embodiment of a lining plate according to the present invention, and FIG. 2 is a sectional view of the lining plate.

The structure of the lining plate of the present invention comprises a lining plate 1, a colored lining plate 6, and a connecting member 7.

First, the lining plate 1 is a colorless, transparent and hard synthetic resin plate made of a vinyl chloride resin to which a tin-based stabilizer has been added, and a rectangular substantially rectangular strip molded using the vinyl chloride resin. As shown in FIG. 1, a plurality of rib pieces 2 parallel to each other are integrally formed on one surface 1a.

Each of the rib pieces 2 is formed along the longitudinal direction of one of the plate surfaces 1a, and a bulging portion 3 having a substantially elliptical cross section is formed at the tip.

As shown in FIGS. 1 and 2, joining pieces 4 are formed on both right and left edges of the lining plate 1 in parallel with the rib pieces 2 in the same direction. The joining piece 4 has a hook-like tip.

Further, the other surface 1 of the lining plate 1
b is formed smoothly. As shown in FIG. 1, a masking sheet 5 made of a resin film is adhered to the other surface 1b, and the entire surface is covered.

The masking sheet 5 is formed, for example, by forming a special polyolefin-based film on one side of an adhesive resin in a layered form, or by forming a polyethylene film on one side of a special acrylic-based adhesive. The other surface 1b of the lining plate 1 is stretched and adhered by an adhesive. In addition, these adhesives have a small adhesive strength, do not cause adhesive residue, and can be easily peeled off.

In addition to the masking sheet 5 described above, polyethylene, polypropylene, polyvinyl chloride,
Various films such as a film made of polyvinylidene chloride and the like, a film made of a copolymer of ethylene and other monomers, and a film formed by mixing two or more of the above resins, are subjected to a corona discharge treatment or an oxidizing agent. An oxidation treatment such as a chemical treatment or a flame treatment is performed, and a heating roll or a heating press treatment is performed on the other surface of the lining plate, and the lining plate is pressed and adhered to form a coating. In addition, this masking sheet 5
According to the method, since no adhesive is used, peeling can be easily performed.

Next, the colored lining plate 6 is formed in substantially the same shape as the transparent lining plate 1 described above, and is a rectangular, substantially strip-shaped plate material (not shown) which is parallel to one side along one longitudinal direction. A large number of rib pieces are integrally formed, and the tip of each rib piece has a bulging portion having a substantially elliptical cross section.
A hook-like joint piece is formed on each of the left and right edges so as to be parallel to the rib piece.

The colored lining plate 6 is made of a hard synthetic resin plate which is colored and opaque by adding a lead-based stabilizer to a vinyl chloride resin and adding a desired coloring agent. Therefore, the width is longer than that of the transparent lining plate 1, for example, twice as long as the transparent lining plate 1 (see FIG. 3). .

Next, the connecting member 7 is made of a synthetic resin such as a colored and opaque vinyl chloride resin to which a lead-based stabilizer is added and which is colored as necessary. As shown in FIG. 8 and a continuous long body having a substantially U-shaped cross section in which a sealing material 9 is mounted.

Next, the procedure for constructing a concrete structure T having the above-described lining plate structure will be described.

First, two transparent lining plates 1 are connected side by side by a connecting member 7 to form a colored lining plate 6.
And a colored lining plate 6 is connected to each outside of both transparent lining plates 1 by a connecting member 7 to form a set of lining plates.

Next, an inner frame 11 for forming the inner wall surface and the ceiling surface of the concrete structure T is assembled, and the lining plates 1 and 6 are temporarily mounted on the surface of the inner frame 11.
In this temporary mounting state, each rib piece 2 of each lining plate 1, 6 faces outward, that is, the other smooth surface 1b of each lining plate 1, 6 is aligned with the inner mold 11, and each rib piece 2 The two lining plates 1 and 6 are attached so that the longitudinal directions of the lining plates 2 are perpendicular to each other and are connected by the connecting members 7.

Next, the outer mold frame 12 is assembled so as to surround the outer periphery of the inner mold frame 11. The outer mold frame 12 is provided with a support member (not shown) at a predetermined distance from the inner mold frame 11, that is, the lining plates 1 and 6, so that each of the lining plates 1 and 6 The rib pieces 2 are arranged so as to face the inside of the inner and outer molds 11 and 12.

Then, concrete C is poured into the gap between the inner mold 11 and the outer mold 12. At the time of this casting, the rib pieces 2 formed on the lining plates 1 and 6
Concrete C flows in along the rib pieces 2, and each rib piece 2 is buried in the concrete C (see FIG. 4).

After the placement of the concrete C is completed, the concrete C is cured and solidified. Then, after the concrete C is solidified, the inner and outer forms 11 and 12 are removed.

In the completed concrete structure T, the rib pieces 2 of the lining plates 1 and 6 serving as inner wall surfaces are buried in the concrete wall, and the concrete C and the lining plates 1 and 6 are buried.
Are integrally formed, and the inner surface of the structure is covered with the lining plates 1 and 6 (see FIG. 3).

After removing the inner and outer molds 11 and 12, the masking sheet 5 covering the other surface 1b of the transparent lining plate 1 serving as the inner surface of the building T is peeled off as shown in FIG. The other surface 1b of the lining plate 1
Is expressed.

Therefore, in the structure of the lining plate 1 configured as described above, the transparent lining plate 1 constituting the inner wall surface of the concrete structure T is made of a colorless and transparent resin.
Buried state of the rib pieces 2 on one side 1a, that is, whether the concrete C has flowed reliably between the rib pieces 2 and the presence or absence of the void can be visually recognized, and the construction state of the concrete C and the transparent lining plate 1 That is, the close contact state can be easily visually recognized.

Further, since the other smooth surface 1b of the transparent lining plate 1 is covered with the masking sheet 5, it can be used at the time of transportation or construction of a concrete structure T or the like.
It is possible to maintain the transparency of the lining plate 1 after the masking sheet 5 after application is peeled off without damaging the transparent lining plate 1 itself.

Further, in the structure of this lining plate, two sets of transparent lining plates 1
Is constructed so as to be integrated with the concrete wall surface as a structure in which the concrete C is connected by the connecting member 7, so that it is also possible to visually check whether the concrete C flows along the connecting member 7 and is buried in the concrete. Become.

Further, since the transparent lining plate 1 and the colored lining plate 6 are arranged in parallel and connected to each other, the wall is constituted by the transparent lining plate 1 and the colored lining plate 6 alternately at a predetermined width. Thereby, on the wall surface of the concrete structure T, the adhesion state between the lining plate 1 and the concrete C can be visually checked at predetermined intervals, and the state of the concrete construction can be confirmed.

In the above embodiment, whether or not the masking sheet 5 is colored is not described, but it is preferable that the masking sheet 5 be transparent or translucent. In this case, the state of the surface of the lining plate 1 can be visually recognized, and the state of the concrete can be visually recognized before peeling.

Further, in the above-described embodiment, an example has been described in which the masking sheet 5 is adhered to the other surface 1b of the lining plate 1 to form a coating.
It is also possible to form the masking sheet 5 in the form of a film at the same time as the molding of the lining plate 1, that is, to form the masking sheet 5 integrally with the lining plate 1.
