DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a directly-placeable round-washable carpet and mat-like flooring material for concrete houses.

<Prior Art> In recent years, westernization of houses has advanced, and carpets have come to be generally used as flooring materials for concrete houses. When laying a carpet on a concrete floor or floor panel, etc., all were fixed to the floor with nails or adhesives. Flooring materials such as carpets have problems of dirt and hygiene (insect resistance, antibacterial property, etc.). On the other hand, as the fashion of interior decoration has spread to the floor surface, it is easy to clean and disinfect the floor surface. And the need for flooring that can be refurbished has come.

<Problems to be Solved by the Invention> The present invention has been developed in view of the above-mentioned current situation of flooring materials, with the object of providing a direct placing type circular washing flooring material having the following properties and functions.

Or, a heli material (E) for covering the side end surface of the above-mentioned ABCD laminate with a cloth and a sheet made of a synthetic resin foam,
(T) indicates thickness, and (W) indicates width.

A feature of the present invention is to provide a structure in which the specified floor surface material, stress dispersion material, core material, and freak prevention material are laminated in order, and the side end surface of the laminate is covered with a rim material or the like, and the thickness (T) Is 25
~ 75mm, width (W) is 20 ~ 100cm, length (L) is width (W)
It is a floor material that can be washed by direct placing and has a density of 1 to 3 times, a density of 50 to 200 Kg / m ³ , and a weight of 15 Kg or less.

The flooring material having the above-described structure according to the present invention, when cleaning and disinfecting the entire floor, peeling off, removing, moving, washing the flooring material,
Carrying, sun drying and laying down, special equipment, equipment,
No tools, no space, etc., size, shape, and
Hardness and weight.

Also, during each of the above work, during work, floor material deforms after work,
It is a material and structure that does not cause peeling or deterioration of each laminated body. In other words, the size, shape, hardness, and weight that can be easily removed to be laid down have a thickness (T) of 25 to 75 mm,
The width (W) is 20 to 100 cm, and the length (L) is 1 to 3 of the width (W)
It is a mat-like material with double the density of 50 to 200 kg / m ³ and the weight of 15 kg or less. Except for the above range and conditions, each work is too large and it is difficult to perform each work. Also, there are problems in each work such as being too main to hold, and there is a risk of injury such as bruising when falling or falling,
There are problems that it is too light and there is a risk of being blown away by the wind, that it is too hard and not practically preferable, and that it is too soft and it is difficult to perform each work such as washing. Also, in terms of ergonomics, the ground,
It is said that the feeling of human security such as being clearly dispersed from the concrete surface is obtained when sitting on an object having a thickness of 25 mm or more and an area of 20 cm × 20 cm or more, and is not obtained in the following cases.

In addition, the above-mentioned structure, in the case of floor remodeling and floor laying with different floor materials, the size, shape, etc. that can be easily implemented in a short time,
This is because the same matters as described above are necessary, and in addition, the structure and material of the back surface of the floor material that can absorb and prevent the freak of the concrete floor are necessary. That is, the mat-like material having the above-mentioned characteristics must be used, and moreover, the back surface of the floor material (the lowermost portion of the structure) must be composed of the freak preventing material. If there is no freak prevention material, naturally, the freak will cause the surface of the floor material to become uneven, causing various problems such as tripping on the floor surface in real life.

In addition, when considering practical use, if the floor material is subject to static load, concentrated load on objects such as furniture and electric appliances, or impact when dropping objects such as tables and chairs, the surface of the floor material A stress dispersive material that can withstand concentrated loads and impacts is required to prevent deformation such as denting or warping. Thickness 1-4 mm, density 400 kg
Must be at least / m ³ . This stress dispersal material is not effective if it is not formed in the upper layer of the floor material as much as possible, but if it is formed on the surface (surface layer), compared to carpets and synthetic resin foam sheets, walking comfort, comfort, The feel, elasticity, etc. are remarkably inferior. Therefore, this stress dispersal material may be placed underneath the carpet or foam sheet material. Also, liquids / solids such as water and salt, chemicals such as thinner and detergent were subjected to various changes such as static / dynamic changes and physical / chemical changes due to each work such as peeling. In addition, it is necessary to have a floor surface material that does not change in quality or discoloration when it is subjected to heat and humidity changes such as heating and cooling, such as a stove, kotatsu, and air conditioner. Therefore, the floor covering is made of synthetic resin-based carpet or synthetic resin foam sheet. If this material is of natural fiber or wood type, it has hygroscopic and water-absorbing properties, it is difficult to dry after washing, expansion and contraction due to moisture absorption and drying, warpage etc. To do. In addition, the thickness (T) of the entire structure does not change even when subjected to the above-mentioned various changes, and the thickness (T) of the entire structure is 25 to 75 mm and the density is 50 to 200 Kg / m ³ A synthetic resin-based foam having a density of 10 to 60 mm and a density of 20 to 100 kg / m ³ is required as a core material. Since this foam has the property of being easily changed by an external force such as compression, and since it is not necessary to directly expose it to the front or back surface of the flooring material, this core material should be placed between the stress dispersion material and the freak prevention material. good.

Next, each material used in the present invention will be described. First, regarding the floor surface material (A), the carpet made of synthetic fiber may have any of the commonly used level loop pile, level cut pile, cut and loop pile, and high and low pile pile shapes.
The level cut pile shape is preferred from the dry side. As a method for manufacturing a carpet, there are tufted, woven, knitted, and adhesive methods, but the tufted method that can use a material that does not absorb water and has a small dimensional change is preferable in terms of cost. The base fabric of the tufted carpet is preferably synthetic fiber such as polypropylene and polyester, and jute and cotton are not suitable as a floor-washing floor because they are water-absorbing and stretchable. The packing material may be any of SBR / PVC / EVA / polyethylene / polyurethane / rubber, and from the viewpoint of cushioning property, the above-mentioned synthetic resin foam is preferable, and especially from the viewpoint of durability and high elasticity, rubber-based foam and Urethane foam is best. Synthetic resin foam sheet is durable
A thermoplastic sheet is preferable from the economical point of view. In addition, the practical feel
From the viewpoint of elasticity, the carpet is preferable to the seat.

Next, as for the stress-dispersing material having a thickness of 1 to 4 mm and a density of 400 kg / m ³ or more, a flexible material having both bending rigidity and tensile force may be used, but the foam has a density of about 800 kg / m ^3. Polyolefin foams are preferred. The thickness is preferably about 2 mm in terms of the thickness and weight of the product of the present invention.

Next, regarding the core material (C) which is a synthetic resin foam having a thickness of 10 to 60 mm and a density of 20 to 100 kg / m ³ , the foam material used in the present invention is generally made of a thermoplastic synthetic resin by a foaming agent. It also includes foamed and optionally crosslinked. Specifically, vinyl chloride-based / EVA / polyethylene polystyrene copolymer / polyurethane-based, polyolefin-based / rubber-based, etc., and polyethylene foam / urethane foam / rubber-based elastic foams that have excellent resilience and impact resistance. Is. For the core material of the present invention, polyethylene / polystyrene copolymer foam, urethane foam, and polyolefin are preferable, and polyethylene is most preferable from the viewpoint of non-water absorption, durability, lightweight, quality stability and the like.

About freak prevention material (D)
A thickness of m or more is required, and a thickness of less than 15 mm is preferable because of the thickness of the product of the present invention, and 7 to 10 mm is preferable. Synthetic fiber felts and synthetic resin foams, which have no water absorption and excellent cushioning properties, are good, but among EVA, polyethylene / urethane foam, and rubber-based synthetic resin foams, rubber-based ones are more durable and cushioned. Is most preferred, for example
The underlay mat for Jiyuutan disclosed in Japanese Patent Publication No. 57-56856 is optimal.

Regarding the above-mentioned edge material (E) for covering the side end surfaces of the laminate of (A), (B), (C), and (D), a non-water-absorbing, more preferably water- and oil-repellent synthetic fiber or synthetic resin system is used. A fabric or a sheet made of a foam may be used, but a water- and oil-repellent plain weave fabric made of polyester is most preferable in terms of non-water absorption, durability, quality stability and the like. This edge material can also be used as a floor surface material, but it is necessary to determine the size of the floor material in consideration of the thickness and elasticity of the floor surface material in terms of the gap after construction. is there. When the floor surface material is also used as the edge material (configured as an integrated material), a carpet having a short pile length and a small packing material thickness is desirable.

Incidentally, the respective laminated bodies and the edge material may be integrated by any one of adhesion, welding and sewing, or a combination thereof. Sewage is preferable because of the slight warp caused by the difference in the characteristics and characteristics of the material of each layer and the ease of replacement of each layer. (B) (C) (D)
A combination of material sewing, (A) adhesion and (E) sewing is also preferable.
