Description

TECHNICAL FIELD The present invention relates to a flat building material, and more particularly to a flat building material made of a mineral material such as marble or tile that is brittle and easily cracked.

[Conventional technology]

Marble is usually processed as a plate material with a thickness of 1 to 2 cm or more and a size of 30 cm square or more and is used as a floor material or wall material, but marble belongs to a heavy material with a large specific gravity among building materials, and it is a wall surface. The construction requires a sturdy temporary frame to support it, and the ALC / foam concrete wall, which is widely used in recent years, may be peeled off and dropped, so it cannot be directly constructed.

[Problems to be solved by the invention] Therefore, flat building materials made of minerals with a large specific gravity are used by thinly processing them like tiles, but they are processed into tiles around 10 cm square. The marble produced does not look good and loses its value as a marble, and the thinner it is, the higher the risk of cracking during transportation. In particular, natural marble, which has a random crystal structure and is expensive, is easily broken, and thus is processed into a large thickness, which requires a great deal of labor for its transportation and construction.

For this reason, it has been attempted to thin and lighten the marble by making a honeycomb (honeycomb) structure with large voids on the back side by adhering it to the back surface, but aluminum is easily bent, and the surface of stacked marbles has aluminum. Scratches due to scratches are likely to occur, and a special surface protection sheet is required for packing.

[Object of the Invention]

Therefore, the main object of the present invention is to provide a flat building material such as marble or granite that does not require a special surface protection sheet for packing, is hard to be broken during transportation, and is light and easy to handle.

[Structure of Invention]

That is, in the composite building material 17 according to the present invention, the front fabric 11 and the back fabric 12 are joined by the binding yarns 13 to form a gap 14 of 3 to 20 mm between the fabrics, and the binding yarn 13 is formed in the gap. But those cloth 11
・ Stand up the double woven structure fiber structure 15 standing upright on 12 to surface material 16 such as inorganic plate material such as marble or granite, woven or knitted material, non-woven fabric, artificial leather, vinyl cloth, interior sheet such as wallpaper, etc. The present invention is particularly effective for an inorganic building material such as a slate plate or a marble plate, in particular, an expensive natural marble or granite building material having a random crystal structure and directional strength. Is.

The double woven / knitted structure fiber structure 15 applied to the present invention is made as an intermediate product in the manufacturing process of pile cloth such as moquette and Wilton carpet, and has a woven / knitted structure and a binding yarn of the front and back cloths 11 and 12. According to the method of tying 13 to the fabrics 11 and 12, by the tufting method of stitching the front and back fabrics piled up as shown in Patent No. 129,890 (Publication No. 5310 of 1948) with pile yarns, As disclosed in Japanese Utility Model Publication No. 50-25825, by the Wilton-Moquette method in which the front and back fabrics are double-woven while being bound by pile yarns.
As shown in No. 60-59336, there is a method by which the front and back fabrics are knitted in double while connecting them with pile yarns, etc.

In the case of manufacturing pile fabric, double woven / knitted structure fiber structure
The binding yarn 13 is cut between the 15 front and back fabrics 11 and 12 to divide into two cut pile fabrics, but in the present invention, the binding yarn 13 is not cut and the front and back fabrics 11 and 12 are joined. Since it is used as the double-woven knitted tissue fiber structure 15 which has been tied,
The woven and knitted structures of the front and back fabrics 11 and 12 do not necessarily have to be the same.

In particular, the composite building material 17 according to the present invention has a double woven or knitted tissue fiber structure 15 on the back side and is adhered to a floor surface or a wall surface with an adhesive such as cement, in which case an adhesive such as cement is used. It is said that the back cloth 12 has a porous woven / knitted structure to facilitate press-fitting into the gaps 14 between the front and back cloths 11 and 12, and the front cloth 11 has a dense woven / knitted structure so as to adhere to the surface decorative material 16. It is advisable to change the woven and knitted structure of the front and back fabrics 11 and 12, and for that purpose, the double woven and knitted structure fiber structure 15 may be knitted by a double Raschel warp knitting machine.

FIG. 2 illustrates a double woven structure fiber structure 15 knitted by the double Raschel warp knitting machine by changing the woven and knitted structures of the front and back fabrics 11 and 12, and the backing fabric 12 has 0.5 It has a net shape with a large opening 18 of cm ² or more.

The size H of the gap 14 between the front and back fabrics is appropriately set by conventional techniques employed to set the pile length of the pile fabric.

Although the yarns constituting the front and back fabrics 11 and 12 may be spun yarns or filament yarns, it is preferable to use thick denier monofilament yarns as the binding yarns 13.

Various adhesives 19 are used to bond the double woven / knitted texture fiber structure 15 and the surface decorative material 16.

The double woven or knitted tissue fiber structure 15 is subjected to resin processing for applying a thermosetting resin solution such as a styrene resin, a phenol resin, a urea resin, or an epoxy resin before and after being bonded to the surface decorative material 16. Well, in particular, when the surface decorative material 16 is an inorganic material such as marble or granite, or slate or porcelain tile, it is effective to perform such resin processing.

When the double woven or knitted tissue fiber structure 15 is subjected to resin processing with a heat-softening resin such as natural or synthetic rubber / latex or acrylic resin emulsion, the heat-softening resin composition is made of an inorganic substance such as cement. It is advisable to add an appropriate amount of adhesive.

〔The invention's effect〕

The composite building material 17 according to the present invention is a double woven / knitted tissue fiber structure 15
Facing toward the back side, an adhesive such as cement is applied and press-fitted into the gap 14 between the front and back fabrics to be adhered to the floor surface or wall surface. (1) In the gap 14, the binding yarns 13 are individually Since the upright and binding yarns are not entangled with each other, the adhesive used during construction is
The adhesive which is easily press-fitted into the binder 14 and is not partitioned into the binder yarns 13 in the gap 14 forms a thick backing layer that reinforces the surface decorative material 16 together with the binder yarns 13. In addition, since the front and back fabrics 11 and 12 are made of fiber yarns that are not easily cracked, the plate surface 16 is less likely to be cracked by the impact applied to the floor surface or the wall surface.

(2) Since the back surface is composed of a porous backing fabric 12, the adhesive used during construction is easily applied, facilitating adhesion to the floor surface or wall surface, and firmly adhering. .

(3) The surface decorative material 16 is a double-woven knitted tissue fiber structure
Since it is reinforced by 15, the thickness L can be reduced, and the overall weight is reduced, which makes it easier to carry and it is not necessary to construct a sturdy temporary frame for its construction.

(4) Since the double woven or knitted fiber structure 15 functions as a cushioning material and protects the surface 16 of the plate material when stacked, no special surface protection sheet is required for packaging.

As described above, the composite building material 17 according to the present invention is lightly and hard to crack, is less likely to be scratched on the surface during the transportation process, is easy to apply, and exhibits strong impact resistance after the application.

Therefore, the present invention is a heavy and fragile marble or granite, or
The weight of the inorganic plate material 16 such as slate or porcelain tile is reduced to improve its impact resistance.

In addition, in the case where the surface decorative material 16 is an interior sheet such as a woven or knitted fabric, a non-woven fabric, artificial leather, vinyl cloth, or wallpaper, a void layer (14) is provided between the interior sheet and a construction base such as a ceiling or a wall surface. Since it can be formed, it is possible to perform interior construction having a cushioning property and a sound absorbing effect without dew condensation. Therefore, the present invention is very advantageous in enhancing the habitability in the room.
