By the way, in the skirting board (corner base material) used conventionally, there are the following three problems (a), (b), and (c).
(A) Workability of corner base material
As a method of constructing the corner base material , a resin sheet is adhered to the front surface (R surface) of the corner base material along the front surface (R surface) of the corner base material, or paint is applied from above the corner base material. May be painted.
When a resin sheet is adhered to a corner base material , the rigidity of the sheet itself differs depending on the thickness of the sheet, the shape of the sheet, and the material of the sheet. There is a sheet (easy to do).
For example, a sheet made of vinyl chloride resin, which is widely used as a floor material, has a relatively high rigidity, so that the sheet of the floor material is continued from the floor surface and mortar or the like is placed on the front surface (R surface) of the corner base material. If you want to adhere using, depending on the shape of the front of the corner base material, sheet does not adhere to the front of the well corner the base material, or become sheet is easily peeled off, craftsmen time been slow work for bonding the sheet Problems such as
In addition, since the upper and lower ends of the conventional corner base material have a U-shaped cross section, dust and dirt tend to collect on the flat surface of the upper end, which adversely affects the adhesion of sheets and the painting of paints, etc. May affect.
(B) Material of corner base material Conventionally used corner base materials are made of resin or metal due to their good workability. However, corner base material is a building that is used mainly market and factories, as many wide total area, such as medical institutions, because it is a fire-resistant buildings or quasi-fire-resistant buildings, corner foundation made not a noncombustible materials resin There is a problem that the material cannot be used. Further, the metal corner base material has a problem of durability such as rust, and is not suitable for a place where a large amount of liquid such as a cleaning liquid or water is used. In addition, when installed in a freezer, if the material is metal, the corner base material itself becomes low in temperature due to its high thermal conductivity, and heat is transferred to the wall surface or floor surface in contact with the corner base material. Therefore, it is considered to use a composite material using cement having heat resistance and low thermal conductivity and coefficient of thermal expansion as a material for a corner base material.
However, the surface of a composite material containing cement is liable to be chipped or cracked due to an external impact depending on the composition and blending amount of the material. Corner base materials are mainly used in markets, factories, medical institutions, etc. and are installed at intersections where the bottom of the wall surface and the floor surface intersect, so trolley wheels, cleaning brushes, vacuum cleaners, etc. may collide. many, corner base material having an improved impact resistance has been required, considering selection and amount of the composition of the composite material used as a corner base material is the most important issue.
(C) Use as a protective material A trolley is used in fish markets, food factories, medical institutions, etc. because it often carries a large amount of food and a large amount of medicines. Although the dolly has the advantage of being able to carry a large amount of luggage at one time, it is difficult to handle, and the dolly may hit the wall and damage the surface of the wall.
Conventionally, the corner base material is attached to the intersection of the wall and the floor, so if the wheel of the dolly or a vacuum cleaner collides with the wall at a position close to the floor surface, the corner base material becomes a protective material and damages the wall. However, if the loading platform of the dolly collides with the wall at a position away from the floor surface , the wall surface is not covered with the corner base material , so the surface of the wall may be damaged or chipped. There is a problem that it ends up.

Therefore, an object of the present invention is to provide a corner base material and a sheet with a corner base material capable of easily and accurately adhering the sheet to the intersection where the bottom of the wall and the floor intersect. do.
Another object of the present invention is a corner base material having excellent heat resistance, impact resistance, frost damage resistance, and water resistance, which are various characteristics required as a corner base material , and is a fireproof building or a semi-fireproof building. An object of the present invention is to provide a corner base material that can be suitably used as a non-combustible material.
The object of the present invention has an object to provide a corner base material capable of protecting the walls even when the cargo bed of the truck has collided.

The present invention, in the corner base material for painting from the upper or either bonded from above the sheet bottom and the floor surface of the wall is used as a mounted and the floor member at the intersection of intersecting, said corner base sheet Contains cement, siliceous powder, aggregate and fiber as the main components, has a strength attenuation rate of 10% or less, a thermal expansion rate of 1.0 to 15.0 × ^10-6 / ° C, and impact strength. Is 0.8 to 25.0 kJ / m ^2, and the thermal conductivity is 0.3 W / mK or less.
According to the present invention, cement, siliceous powder, aggregate and fiber are contained as main components, the strength attenuation rate is 10% or less, and the coefficient of thermal expansion is 1.0 to 15.0 × ^10-6 / ° C. To obtain a corner base material having heat resistance, impact resistance, and frost damage resistance when the impact strength is 0.8 to 25.0 kJ / m ² and the thermal conductivity is 0.3 W / mK or less. Is possible.
The material used is a corner foundation member, the corner when used in a cold district, if the indoor using corner underlying material becomes a high temperature in summer, when such a fire occurs, without deformation even when the temperature changes It is important that the strength of the base material is constant. The intensity decay rate of the corner base material is greater than 10%, a cold district or summer, etc., the strength of Corner underlying material when the temperature decreases and increases extremely reduced, collision of the wheels or the like of the vacuum cleaner and trolley It will be chipped or cracked depending on the type. If the intensity decay rate of the corner base material is 10% or less, it becomes possible to obtain a corner base sheet having excellent heat resistance required as a corner base material, also be used for many years in a room to be cold regions and the hot Is possible.
Further, when the temperature changes indoors or the like, the mixed material having cement generally expands due to the change in temperature, so that the mixed material may crack. If the coefficient of thermal expansion of the corner base material ^{is larger than 15.0 × 10 -6} / ° C, it is vulnerable to temperature changes, and cracks occur in the corner base material due to sudden changes in temperature such as in cold regions and summer. Since the thermal expansion rate of the cement is 1.0 × ^{10 -6} / ℃, the thermal expansion coefficient of the corner base material is 1.0 × ^{10 -6} / ℃ the minimum value. By setting the coefficient of thermal expansion of the corner base material ^{in the range of 1.0 to 15.0 x 10-6} / ° C, expansion due to heat is suppressed even if a temperature change occurs, and it is caused by a general indoor temperature change. It is possible to prevent cracks from entering the corner base material.
Furthermore, if the thermal conductivity of the corner base material is 0.3 W / mK or less, heat transfer to the wall surface or floor surface in contact with the corner base material is minimized even when the corner base material becomes hot. This makes it possible to use it suitably as a non-combustible material for fireproof buildings and the like. When the thermal conductivity of the corner base material is greater than 0.3 W / mK, it would then transfer heat to the wall or floor surface, and unsuitable as a nonflammable material.
In addition, by setting the impact strength of the corner base material ^{to 0.8 to 25.0 kJ / m 2} , even if the corners of the dolly carrier, wheels, cleaning brushes, etc. collide, they may be chipped or broken. It is possible to provide a corner base material having improved impact resistance, and further, it is possible to use it as a protective material for protecting the wall surface. If the impact strength of the corner base material ^{is less than 0.8 kJ / m 2} , it may be easily broken by the impact of a colliding object. The impact strength maximum of the corner base sheet from the characteristics of the materials used in the corner underlying material becomes 25.0kJ / m ^2.

Of the present inventionCorner base materialIs characterized in that the water absorption rate is 40% or less.
Composite materials containing cement generally easily absorb moisture, and the absorbed moisture freezes inside the composite material in places where the temperature is low, such as in cold regions. If the water absorption rate is larger than 40%, the solidified water expands, causing cracks such as cracks in the composite material.
According to the present inventionCorner base materialBy setting the water absorption rate to 40% or less, the expansion of the absorbed water at low temperatures is minimized, and it has excellent frost damage resistance that can be suitably used even in cold regions. Corner base materialCan be provided.

Further, the present invention is characterized in that the volume change rate when the corner base material is immersed in water and is repeatedly frozen and thawed is 10% or less.
The corner base material of this application is assumed to be used mainly in markets, factories, medical institutions, etc., and in such places, rain may enter and a large amount of liquid such as cleaning liquid or water may be used. Water resistance is very important as a characteristic of the corner base material because it is possible that the corner base material is flooded. Also, due to the characteristic that the composite material containing cement easily absorbs moisture, changes in temperature in cold regions, etc. Moisture absorbed by the corner base material repeats freezing and thawing when used in a severe place. Problems and cracks the volume change rate when repeated freezing and dissolution is peeled off the surface of greater than 10% and Corner base material is generated occurs.
According to the present invention, by dipping the corner base material in water is set to lower than or equal to 10% volume change rate when repeated freezing and melting, co Na base even if the change in temperature is used in locations subject strength without delamination and cracks in wood is generated, it is possible to provide a corner base sheet having excellent water resistance constant.

The corner base material of the present invention contains 30 to 65% by mass of cement, 20 to 41% by mass of siliceous powder, 8 to 31% by mass of aggregate, and 2 to 11% by mass of fibers as main components. It is characterized by that.

The sheet 100 is a sheet-like floor material that adheres from above the corner base material (Fig. 1), and is used on the floor surface in places where rain invades or a large amount of liquid such as cleaning liquid or water is used. It is made of the best material for mounting. Specifically, a material having excellent impact absorption and anti-slip properties, such as a soft vinyl chloride resin, a foamed soft vinyl chloride resin, or a combination thereof, is used. The thickness of the sheet 100 is about 4 mm.
The panel 200 is a decorative panel for a wall used for the interior of a building, and has a wide plate shape, which is higher than the upper part of the wall surface Q, specifically, the position where the corner base material 10 is attached to the wall surface Q. It is attached to the upper part of the paper (Fig. 1).

The joint material 300 is a member that connects the sheet 100 and the panel 200, has an H-shaped cross section, and is extruded from a resin or aluminum material. By sandwiching the panel 200 and the sheet 100 in the opposite grooves 300a and 300b of the joint material 300, the sheet 100 and the panel 200 are joined without using a filler such as a caulking material or a sealing material. The joint material 300 maintains waterproofness and airtightness between the panel 200 and the sheet 100, and solves problems such as aging deterioration and aesthetics that occur when a filler is used, and the thickness of the sheet 100 and the panel 200. Since they are formed to be substantially the same, it is possible to make the joints look beautiful.

The material of the corner base material contains cement, siliceous powder, aggregate, and fiber as main components, and is formed as a non-combustible material by the above materials.
For the corner base material, each of the above components is mixed at an appropriate mixing ratio (mixing step), and an appropriate amount of water is added for kneading (kneading step). The kneaded mixture is supplied to an extrusion molding machine and extruded to obtain an extrusion molded product (extrusion molding step). After that, the obtained extruded body is cured and dried to obtain a corner base material (curing / drying step).
The corner base material may be integrally molded by extrusion molding, or the flat member 11 and the curved surface member 12 may be separately formed and joined to be molded.

Examples of cement include various Portland cements such as ordinary, fast-strength, sucrose heat, low heat, and sulfate-resistant cements, belite-rich cements, alumina cements, blast furnace cements, fly ash cements, and water-hard cements such as various mixed cements. The blending ratio of cement is in the range of 30 to 65% by mass, preferably in the range of 35 to 55% by mass.

Silica powder is a component used to improve the waterproof function of the corner base material , and examples thereof include silica stone, diatomaceous earth, microsilica, and silica fume, and silica stone is particularly suitable. The compounding ratio of the siliceous powder is in the range of 20 to 41% by mass, preferably in the range of 25 to 37% by mass. If the compounding ratio of the silicic acid powder is less than 20% by mass, the waterproof effect cannot be obtained, and if the compounding ratio of the silicic acid powder is larger than 41% by mass, the strength of the corner base material decreases.

Aggregate is a component used to suppress heat generation and contraction during curing, and examples thereof include sand, fly ash balloon, silas balloon, pearlite balloon, obsidian balloon, perlite, vermiculite, canamite, and glass microballoon. The compounding ratio of the aggregate is in the range of 8 to 31% by mass, more preferably in the range of 12 to 26% by mass. If the compounding ratio of the aggregate is less than 8% by mass, an appropriate heat generation and suppressing effect cannot be obtained, and if the compounding ratio of the aggregate is larger than 31% by mass, the strength of the corner base material decreases.

Fiber is a component used to enhance frost damage resistance such as crack prevention of corner base material and improvement of bending strength, and organic fiber such as pulp, waste paper, polyamide fiber, polyester fiber, polypropylene fiber, vinylon fiber and glass. Examples thereof include fibers and inorganic fibers such as carbon fibers, and pulp is particularly preferable. The blending ratio of the fibers is in the range of 2 to 11% by mass, more preferably 2.5 to 8% by mass. Fibers not suitable effect can be obtained such as improvement of the crack-deterring and bending strength that is less than 2 mass% blending ratio of the mixing ratio of the fiber strength of 11% by weight greater than the corner base material is lowered.

The corner base material obtained by mixing each of the above components in the above blending ratio is excellent in heat resistance, impact resistance, frost damage resistance, and water resistance, and is suitable as a non-combustible material. Specifically, the strength attenuation rate is 10% or less, the coefficient of thermal expansion is 1.0 to 15.0 × 10 ^-6 / ° C, the impact strength is 0.8 to 25.0 kJ / m ^2, and the thermal conductivity is high. It is preferable that the water absorption rate is 0.3 W / mK or less and the water absorption rate is 40% or less. Further, it is preferable that the volume change rate when the corner base material is immersed in water and repeated freezing and thawing is 10% or less because it is excellent in water resistance and frost damage resistance.

While maintaining the rate of increase in the first inclination angle of the curved surface 19 provided on the lower front portion of Corner base sheet 10 (angle of the front corner base member relative to the floor surface) constant is curved sheet 100, then the sheet At a point where 100 is sufficiently curved (a point where the shape changes from a curved surface 19 to a flat surface 18), an inclination angle (a corner based on the floor surface P) is formed at a flat surface 18 provided on the upper front surface of the corner base material 10. The angle of the front surface of the base material 10) is kept constant so that it follows the wall surface Q. Here, without well abut the radius R of the arc shape of the curved surface 19 of the corner base sheet 10 is too small sheet 100 is a curved surface 19 of the corner base member 10, occurs floats phenomenon, similarly, the When the inclination angle θ of the plane 18 relative to the back surface 14 is too small, without well abut the plane 18 of the sheet 100 corner base sheet 10, it floats phenomenon occurs. However, the radius R of the arc shape of the curved surface 19 of the U Na base material 10, by suitably selecting the inclination angle θ of the plane 18 of the corner base member 10, a curved surface 19 and the plane 18 of the corner base sheet 10, the sheet The phenomenon that floating occurs between 100 is eliminated, and the sheet can be adhered in close contact with the corner base material 10.
Then, by sandwiching the upper part of the sheet 100 in the groove 300b of the joint material 300, the joint material 300 and the sheet 100 are joined with an adhesive or the like.

The above-mentioned mounting method was a mounting method in which the sheet 100 is mounted at the intersection of the wall surface Q and the floor surface P using the corner base material 10, but when painting, it reaches the lower end of the joint material 300 fixed on the wall surface. If the coating is applied and the groove of the joint material 300 is applied, the coating will not easily come off.

When the corner base material 10 of the present embodiment is used, even if there is a problem such as a gap at the joint of the intersection where the lowermost portion of the wall surface Q and the floor surface P intersect, the chamfered portion 13 exists, so that the wall surface Q has a problem. It can be suitably attached to the intersection of the bottom and the floor surface P intersect and the inclination angle θ of the arc shape of radius R and the plane 18 of the curved surface 19 of the corner base material 10 by appropriately selecting , The sheet 100 can be appropriately adhered to the corner base material 10.
Further, since the thickness of the upper end portion and the lower end portion of the corner base material 10 gradually decreases toward the tip, the vicinity of the boundary between the front surface and the wall surface of the corner base material 10 and the vicinity of the boundary between the front surface of the corner base material and the floor surface. The sheet adhesive surface of the sheet is smooth, and even when the sheet 100 is adhered from above the corner base material , a step is less likely to occur around the boundary, and the aesthetic appearance is improved. Further, since the boundary periphery is gentle, it is possible to easily and neatly finish the boundary periphery, which requires the most skill when adhering the sheet 100 neatly.
And because the cross section of the upper and lower ends of the corner base member 10 is the R-shape, the upper and lower ends of the corner base member 10 hardly accumulate dust and dirt, it adheres satisfactorily sheets 100 and Can be painted with paint or the like.
