Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile unit having noncombustibility and flexibility which is used for floor surface construction when the lower part of a balcony is used as a living room.

[0002]

2. Description of the Related Art In the case where a balcony is provided, floor materials such as a cage, tiles, and artificial grass are laid on the floor surface to improve walkability and aesthetics.

By the way, in a two-story or more multi-story building, the lower floor of the balcony on the upper floor may be used as a living room on the lower floor. In this case, especially in a wooden building house, the floor of the balcony on the upper floor also serves as the roof of the lower floor, so the floor of the balcony must have a non-combustible structure under the Building Standards Act.

[0004]

Conventionally, it has been considered to lay tiles, which are refractory, in order to make the floor of the balcony nonflammable. However, the tiled construction is
Usually, it is very time-consuming and costly, and therefore, it is the present situation that it is rarely used for balcony floor construction.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a material having both the properties of a floor material and a roofing material, which can inexpensively make a balcony floor surface a noncombustible tile floor surface without requiring large-scale construction. For the purpose of provision. The feature of the tile unit adopted by the present invention to achieve the above object is that it has a non-combustible performance composed of a core material formed of a woven or non-woven fabric and a coating layer composed mainly of an inorganic material for coating the core material. A plurality of tiles are attached to the surface of the provided sheet-shaped substrate.

As the inorganic material component forming the coating layer of the sheet-like base material, either one or both of aluminum hydroxide and calcium carbonate is used. Since aluminum hydroxide undergoes an endothermic reaction at high temperatures, the incombustibility can be improved by blending this in the coating layer as an aggregate. The same effect is exerted for calcium carbonate.

By the way, usually, an adhesive such as mortar is used to attach the tile to the sheet-shaped substrate, but when a resin binder is blended in the coating layer of the sheet-shaped substrate, this resin is used. It is possible to attach the tile by using the adhesiveness of the binder. That is, by coating the surface of a core material formed of a woven or non-woven fabric with a coating layer containing an inorganic material as a main component and a resin binder, and then attaching a plurality of tiles before the coating layer is cured. ,
A tile unit can be manufactured.

[0008]

The tile unit according to the present invention comprises a non-combustible sheet-like substrate formed by coating a core material with a coating layer containing an inorganic material as a main component, and a tile, which is a refractory material, is attached to the sheet material. Therefore, it has excellent incombustibility as a whole. Therefore,
If this is laid on the floor of the balcony, the surface of the balcony can be covered with a non-combustible material, so that excellent non-combustibility can be provided.

Since the core material is a woven or non-woven fabric having flexibility, the tile unit according to the present invention has flexibility. Therefore, it is possible to easily deal with the unevenness of the laid floor surface, and thus the workability is good. Therefore, the tile floor surface can be easily installed on the balcony.

【Example】

[First Embodiment] FIG. 1 shows a tile unit U according to the present invention.
2 shows a first embodiment of the above. Same tile unit U
Is a plurality of tiles T adhered to the surface of the sheet-shaped base material S at predetermined joint intervals.

Sheet-like substrate S used in the first embodiment
As shown in FIG. 2, has a multi-layer structure including a core material 3 and coating layers 1, 2, and 4. That is, from the surface side (upper side of the drawing), a resin binder (acryl-based synthetic resin, modified vinyl acetate vinyl acetate) containing a relatively large particle size crushed sand layer 1, calcium carbonate as a main component, and a small amount of aluminum hydroxide mixed therein It is composed of a surface coating layer 2 bonded with a copolymer or vinyl chloride resin, a core material 3 made of a glass fiber non-woven fabric, and a back surface coating layer 4 having substantially the same composition as the surface coating layer 2.

The total thickness of the sheet-shaped substrate S is about 2 to 3 mm.
Is. Further, the mixing ratio of calcium carbonate in the front surface coating layer 2 and the back surface coating layer 4 is about 70 to 80%, the mixing ratio of aluminum hydroxide is about 10 to 20%, and the addition amount of the resin binder is about 5 to 10%. is there. However, the blending ratio is not limited to any particular value and may be appropriately changed depending on the type of material used.

The surface of the sheet-like substrate S, that is, the crushed sand layer 1
The tile unit U is manufactured by sticking and arranging the tiles T on top of the tiles. Mortar M is generally used to attach the tile T to the base material S, but a synthetic resin adhesive may also be used. Further, if the hot melt adhesive is used, the process of attaching the tile T to the base material S can be automated, so that the tile unit U can be mass-produced.

Since the tile unit U thus obtained is composed of the non-combustible sheet-like base material S and the tile T, it has fire resistance as a whole. In addition, the sheet-shaped substrate S
Since the non-woven fabric is thinly formed by using a flexible non-woven fabric as the core material 3, it has flexibility and is lightweight, so that it is excellent in workability. Therefore, by laying this tile unit U, a noncombustible floor can be easily installed on the balcony.

At the time of construction, in order to enhance waterproofness, an asphalt roofing material may be laminated on the lower surface of the sheet-like base material S, and this may be applied using a rubber asphalt adhesive.

[Second Embodiment] With respect to the specific structure of the sheet-like base material S in the tile unit U according to the present invention,
Various changes are possible. An example in which the sheet-shaped substrate S has a different structure is shown in FIG. Explaining the structure of the sheet-shaped substrate S shown in the same figure, the crushed sand layer 5 having a relatively large particle size from the surface side is mainly composed of aluminum hydroxide, and colloidal silica, iron oxide, calcium carbonate, glass chops, etc. A surface coating layer in which a small amount of an inorganic material is combined with a resin binder, a first core material 7 made of a polyester nonwoven fabric mixed with glass fibers, and a main component having substantially the same composition as the surface coating layer 6 is aluminum hydroxide. The intermediate layer 8, the second core material 9 made of a polyester nonwoven fabric mixed with glass fibers, the back surface coating layer 10 having substantially the same composition as that of the surface coating layer 6, and silica sand having a relatively small particle size at the lowermost position. It is composed of a silica sand layer 11.

The sheet-shaped substrate S has a total thickness of about 3 mm, and the first core member 7 and the second core member 9 each have a thickness of about 0.3 mm. Further, the front surface coating layer 6, the intermediate layer 8, and the back surface coating layer 10
The mixing ratio of aluminum hydroxide is about 75-80
%, The proportion of other inorganic materials is about 10 to 15%, and the amount of binder added is about 10%. However, also in this example, the above-mentioned mixing ratio is by no means limited, and may be appropriately changed according to the type of material used.

The tile unit U according to the second embodiment is
Since the number of constituent layers of the sheet-shaped substrate S is larger than that of the first embodiment, not only fire resistance but also waterproofness and weather resistance are excellent. Of course, since the sheet-shaped base material S is formed by thinning a flexible non-woven fabric as a core material, it has flexibility and therefore has good workability. However, the weight is slightly increased as compared with the tile unit of the first embodiment.

[Third Embodiment] In the tile unit U of the first and second embodiments described above, the surface coating layer 6 is mixed with a resin binder. The purpose of compounding the resin binder is to bond the coating layer.
It can also be used to attach. For example, as shown in FIG. 4, in the tile unit U (see FIG. 3) of the second embodiment, the surface coating layer 6 is exposed in the uncured state on the outermost surface of the sheet-shaped substrate S, and the tile T is placed thereon. Press into. As a result, the tile T is attached by the resin binder in the surface coating layer 6 and fixed to the surface coating layer 6 after curing. Therefore, this embodiment has an advantage that the tile T can be attached without using mortar.

The crushed sand layer 5 on the surface of the sheet-shaped substrate S
Although it may be omitted in the third embodiment, it may be formed only in the joint portion 20 between the tiles T as shown in the drawing. In this case, in the tile unit U of the second embodiment, a method of scraping off the portion of the crushed sand layer 5 on the surface of the sheet-shaped substrate S to which the tile T is attached, the crushed sand layer 5 excluding the attachment portion of the tile T in advance. A method of forming the crushed sand layer 5 on the joint after the tile T is attached to the surface coating layer 6 and the like can be considered.

[Other Examples] The present invention can be implemented in various modes other than the above. For example, the sheet-shaped substrate S
In addition to glass fiber and synthetic fiber, natural fiber, metal fiber, rock wool, pulp and the like can be used as the material of the core material. As the inorganic material for coating the core material, calcium carbonate and aluminum hydroxide were mainly used in the above examples, but the mixing ratio thereof can be appropriately changed depending on the conditions as described above, and other inorganic materials can be used. The use of compounds is also possible. The type of resin binder is also not particularly limited.

Further, regarding the size of the tile unit, the specific shape such as the number of tiles to be attached per sheet,
It will be changed according to the construction situation.

The tile unit according to the present invention can be applied to the above-mentioned balcony whose lower part is a living room, and a flat roof which uses the rooftop as a playground or a garden. Besides, the embodiments of the present invention do not prevent appropriate changes.

[0024]

The tile unit according to the present invention has both the non-combustibility required for the roof material and the workability required for the floor material. Therefore, for example, on the floor surface of the balcony whose lower part is the living room. It has the effect that it can be laid and the non-combustible tile floor surface can be easily constructed.
