Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved tile base material which can be obtained by easily constructing a tiled curved surface of a building.

[0002]

2. Description of the Related Art Generally, as a method of obtaining a tiled curved surface of a building, a curved formwork is assembled after reinforcement reinforcement and poured into fresh concrete, and after a curing period of several days, the formwork is removed, and the uneven portion is mortared. A method is used in which the tile is attached with an adhesive for tiles or cement for tiles after adjusting it by painting to make a curved tiled base. Such a method is considerably troublesome in terms of construction method, and therefore the construction period is long and the cost is high.

[0003]

SUMMARY OF THE INVENTION The present invention is to provide a curved tiled base material which can obtain a tiled curved surface by a simple construction without requiring the conventional troublesome construction method.

[0004]

In order to achieve the above object, the curved tile base material of the present invention has a waterproof property and an adhesive property of a tile adhesive on the surface of a ceramic type inorganic plate which can be dry-processed and bent. The invention is characterized in that a coating layer for imparting the above is provided, and bending work can be easily performed according to the curved surface foundation of a building, and tiles can be directly attached onto it.

As the ceramic-based inorganic plate in the present invention,
Slag gypsum cement board, calcium silicate board, asbestos slate board, wood chip cement board, wood wool cement board, GR
Fiber-reinforced cement boards such as C and CFRC, other ceramic-based non-combustible building materials, and their asbestos-free base materials can be used.

As the inorganic hardening component of the inorganic plate raw material, ordinary portland cement, granulated blast furnace slag, gypsum dihydrate, semi-water gypsum, anhydrous gypsum, siliceous raw material, calcareous raw material and the like can be used.

As the fibers of the inorganic plate raw material, pulp, wood wool, wood chips, hemp, polypropylene fibers, polyethylene fibers, polyvinyl alcohol fibers, polyamide fibers, polyacrylic fibers and other organic fibers, rock wool, glass wool, carbon fibers, and various other types. Inorganic fibers such as inorganic whiskers and other mineral fibers can be used.

Further, as the aggregate of the inorganic plate raw material, fly ash, silica fume, reactive aggregate such as diatomaceous earth, perlite, radiolite, shirasu powder, calcium carbonate, talc, bentonite, sepiolite, zeolite, edinite, Unreacted aggregate such as wollastonite can be used.

[0009] These substrates are very flexible and can be easily bent by human power because they can be applied to curved surfaces of buildings, and at the same time, cracks must not be formed on the front and back surfaces during bending. ..

Conventionally, a fiber reinforced gypsum board (trade name: F) has been used as a non-combustible material for bending a curved surface of a building.
There are G board, RG board), fiber reinforced slag gypsum cement board, etc., but before they are bent, they are immersed in water to absorb water, and then gradually bent.

The mechanism of bending after soaking in water is to add water to dissolve crystals in the case of gypsum board to weaken the bond strength, and to add hydrate gel to xerogel in the case of ceramic board. To hydrogel for softening, and the shape during bending is retained by the reinforcing fiber.

In comparison with these, the ceramic-based inorganic plate of the present invention can be bent as it is without being dipped in water, so that cracks do not occur on the front and back surfaces after bending.

In order to obtain a ceramic-based inorganic plate having such characteristics, it is necessary to make the composition and composition of the hydrate itself flexible and elastic even in the absence of water. In addition, it is necessary to pay sufficient attention to reinforcing fibers and aggregates.

A preferable characteristic value for providing these characteristics in a well-balanced manner is a bulk specific gravity of 1.0 ± 0.3 g.
/ Cm ³ , flexural strength, when measured with JIS A 1408 No. 3 test body, was large enough to cause no breakage,
Eventually it slips off the support. The yield point is not found even when the width of the test piece is doubled in the length direction and the deflection is reduced to measure. Even with such a flexible board, an impact value of 15 mm or less is necessary because the board is too soft if it is too soft.

Further, in order to obtain the curved tile base material of the present invention, a coating layer for imparting waterproofness and adhesion of a tile adhesive is provided on the surface of the ceramic inorganic plate. The coating film can be obtained by coating a polymer material, and as the coating material, acrylic resin, urethane resin,
Epoxy resin, SBR, other latex, vinyl acetate resin, ethylene vinyl acetate resin, vinyl urethane, PVA, etc. are used. A flexible resin such as a latex-based or ethylene vinyl acetate-based resin is preferable because it does not crack when the substrate is bent and easily follows the substrate.

As a coating method, both the waterproof property and the adhesive property of the tile adhesive may be obtained by one coating layer by one coating, but two coatings by two or more coatings may be performed. You may make it obtain a coating layer more than one layer. In addition, it is also possible to mix silica sand and other aggregates in these coating resins.

The shape of the curved tile base material of the present invention is as shown in FIG. 1, in which 1 is a curved tile base material, 2 is a ceramics inorganic plate, and 3 is a coating layer. Further, in order to physically improve the adhesiveness of the tile adhesive, there is also a method of forming a concavo-convex pattern on the surface of the ceramic inorganic plate as shown in FIG.

The thus-obtained curved tile base material is attached with nails, screws, etc. while bending it in a dry manner in accordance with the curved surface foundation of a building, and then the tile is attached with a tile adhesive or tile cement.

An example of a concrete construction method and procedure for obtaining a tiled curved surface of a building by using the curved tile base material of the present invention is as follows. (1) As shown in FIG. 3, a curved frame member 5 is attached to a steel base 4 of a building frame, and a bar member 6 is attached to the curved frame member 5 to form a curved base. (2) As shown in FIG. 4, the curved tile base material 1 of the present invention is attached to the bar material 6. (3) As shown in FIG. 5, the tile 7 is attached to the curved tile base material 1 with a tile adhesive or tile cement.

In order to provide preferable characteristics as a ceramic-based inorganic plate in the present invention, a hydrate having flexibility, flexibility and plasticity is selectively produced, and at the same time, the kind and amount of reinforcing fiber, and bone. A good combination of wood type and quantity is required.

Calcium aliminate trisulfate hydrate (hereinafter abbreviated as TSH) is the most suitable hydrate. TS obtained at room temperature and steam curing
H has a needle-like crystal structure, has the property of expanding during the crystal growth process, and can relatively easily form a large crystal. It is considered that TSH exhibits strength due to the entanglement of crystals and the effect of filling voids during the crystal growth process, and is particularly effective for bending strength.

As a method for selectively producing a large amount of TSH, there is a manufacturing method described in the specification of Japanese Patent Publication No. 31468/1989 by the present inventor, in which the kind and blending amount of organic fiber, and An inorganic plate having the above-mentioned properties can be obtained by considering the type and amount of the aggregate.

Among these, the role of the organic fibers is to prevent cracks on the front and back surfaces of the inorganic plate when it is bent in a dry manner, to impart shape retention, to complement flexibility, and to take into account nonflammability and cost. It is necessary to determine the compounding amount.

The role of the aggregate is to improve the workability during the production of the inorganic plate, increase the surface hardness, etc., and the particle size distribution, shape and morphology of the aggregate to be blended must be taken into consideration. Especially when relatively long organic fibers are used, the particle size distribution, shape, and morphology of the incorporated aggregate greatly affect the workability during the production of the inorganic plate. That is, when the amount of organic fiber having a long fiber length is increased without adding asbestos,
Since it is not possible to increase the blending ratio of other organic fibers in consideration of noncombustibility, the freeness becomes high and the workability at the time of papermaking is lowered. To compensate for this, it is necessary to reduce the freeness by incorporating an aggregate having a relatively small particle size. Actually, the type of organic fiber, fiber length, blending amount,
Various combinations are possible depending on the type of aggregate, particle size distribution, shape, and morphology.

The method for forming the inorganic plate in the present invention may be any of paper forming (circle-net type, Fourdrinth-type), compression molding, extrusion molding, and mold forming.
