Description

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 the wall surface of a concrete structure such as a sewerage facility, its structure, and its construction method.

[0002]

2. Description of the Related Art Tanks such as sewage treatment tanks and septic tanks of sewerage facilities are generally constructed of concrete. And
These tanks have a hermetically sealed structure so that gas and the like generated from sewage contained therein do not leak out.

However, the generated gas, bacteria in sewage and sewage sludge, etc. cause corrosion and damage to the concrete on the inner wall surface of the tank.

Therefore, 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 concrete to protect the concrete surface.

Such a lining plate construction uses a resin lining plate which is formed in the shape of a rectangular flat plate and has a large number of rib pieces formed in parallel with each other on one surface. This lining plate is attached to the formwork in advance, and when the concrete solidifies after placing and curing the concrete, the concrete surface is covered with the lining plate. Spread this lining plate on the inner wall of
There is a construction method in which concrete or mortar is filled between the corrosion inner wall surface from which the corrosion layer has been removed and the lining plate, and the inner wall surface is covered and restored.

[0006]

However, since the above-mentioned conventional lining plate is a colored and opaque plate material, concrete solidified as a wall surface closely adheres to the lining plate without a gap, that is, between the rib pieces. There was a drawback in that it was not possible to visually confirm that the rib pieces were surely buried in the concrete when it was poured into the concrete.

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

Then, the presence or absence of such a void was checked by hitting it with a gavel or the like from the surface of the lining plate, but it had a drawback that it was a complicated work and could not be easily found. .

Therefore, in order to solve the above-mentioned problems, the present invention provides a lining plate and its structure which can easily judge the state of covering the concrete wall, that is, the state of close contact between the concrete and the lining plate, during lining construction. It is intended to provide a method for constructing this 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 containing a tin-based stabilizer as a raw material, and a rectangular rectangular strip formed by using the vinyl chloride resin. As shown in FIG. 1, a large number of rib pieces 2 that are parallel to each other are integrally formed on one surface 1a of the plate-like plate material.

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

Further, as shown in FIGS. 1 and 2, joint pieces 4 are formed on both left and right 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 this lining plate 1
b is formed smoothly. As shown in FIG. 1, a masking sheet 5 made of a resin film is attached to the other surface 1b to cover the entire surface.

The masking sheet 5 is, for example, one having a layer of adhesive resin formed on one surface of a special polyolefin film, or one having a special acrylic adhesive formed on one surface of a polyethylene film. The other surface 1b of the lining plate 1 is spread and attached by an adhesive. In addition, these adhesives have a small adhesive force, and can be easily peeled off without leaving an adhesive residue.

In addition to the above-mentioned masking sheet 5, polyethylene, polypropylene, polyvinyl chloride,
Various films such as a film made of polyvinylidene chloride, a film made of a copolymer of ethylene and another monomer, a film made of a mixture of two or more of the above resins are treated with corona discharge treatment or an oxidizing agent. Oxidizing treatment such as chemical treatment and flame treatment is performed, and the other surface of the lining plate is subjected to heating roll or heating press treatment and pressure-bonded to adhere to form a coating. In addition, this masking sheet 5

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 strip-shaped plate material, which is not shown but is parallel to each other along one side along the longitudinal direction. A large number of rib pieces are integrally formed, and the tips of the rib pieces each have a bulging portion having a substantially elliptical cross section.
Further, a hook-like joining piece is formed on both left and right edges in parallel with 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 stabilizer to vinyl chloride resin and a desired colorant. Since the transparent lining plate 1 has the property of being more flexible than the transparent lining plate 1, the width is larger than that of the transparent lining plate 1, and is set to, for example, twice the length (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 required, and as shown in FIG. 8 is a continuous elongated body having a substantially U-shaped cross section and having a sealing material 9 mounted therein.

Next, the outer mold 12 is assembled so as to surround the outer circumference of the inner mold 11. A support member (not shown) is interposed between the outer mold 12 and the inner mold 11, that is, the lining plates 1 and 6, so that each of the lining plates 1 and 6 is provided. 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 placed in the gap between the inner mold 11 and the outer mold 12. At the time of this placement, 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 casting of the concrete C is completed, the concrete C is cured and solidified. Then, after the concrete C is solidified, the inner and outer molds 11 and 12 are removed.

In the finished concrete structure T, the rib pieces 2 of the lining plates 1 and 6 which are the inner wall surfaces are buried in the concrete wall, and the concrete C and the lining plates 1 and 6 are reinforced.
And are integrally molded, 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, as shown in FIG. 3, the masking sheet 5 covering the other surface 1b of the transparent lining plate 1 which is the inner surface of the construct T is peeled off, and the transparent The other surface 1b of the lining plate 1
Express.

Therefore, in the structure of the lining plate 1 thus constructed, the transparent lining plate 1 forming the inner wall surface of the concrete structure T is made of a colorless and transparent resin, so that the transparent lining plate 1 for the concrete C is formed.
The buried state of the rib piece 2 on the one surface 1a, that is, whether or not the concrete C is surely flowing between the rib pieces 2 can be visually recognized whether or not there is a gap, 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 is possible to carry it during transportation or when constructing a concrete structure T or the like.
It is possible to maintain the transparency of the lining plate 1 after peeling the masking sheet 5 after the construction without damaging the transparent lining plate 1 itself.
