Description

  The present invention relates to a baseboard, a seat with a baseboard, and a decorative structure of a floor and a wall used at an intersection where the lowermost part of a wall surface and a floor surface intersect.

Generally, baseboards are arranged at the intersections where the floor and the floor of a semi-outdoor underground parking lot, fish market, food factory, clean room, medical institution, etc. intersect. Normally, in locations such as the above, when rain enters or when a large amount of liquid such as cleaning liquid or water is used, liquid flows into the intersection where the bottom of the wall and the floor intersect, corroding the concrete. I will let you. Moreover, in clean rooms and medical institutions, dust and the like enter the intersections, which deteriorates the hygiene condition in the room.
Therefore, by arranging the baseboard, liquids such as dust and water are prevented from entering the intersection, and dust and airtightness are provided, and the intersection is kept hygienic.

As a prior art, there is one in which a portion exposed to the front as a baseboard arranged at an intersection has an R-surface shape, and the following is disclosed.

The R-baseboard body portion 3 bends a stainless plate into a substantially J-shaped cross section It is a long material manufactured by processing. The filler 15 is filled between the R baseboard main body 3 and the wall surface W and the floor surface F, so that the shape between the R baseboard main body 3, the wall surface W and the floor surface F is in its shape. In addition, since it can be covered with the filler 15 without a gap, scattered matter such as water and food is prevented from entering between the R baseboard 1 and the wall surface portion W and the floor surface portion F.
Patent Document 2 relates to a method for constructing a painted floor of a building, particularly a floor-to-wall joint, and a baseboard sheet used in the floor, and to a corner of a joint between a floor base and a wall.

JP 2006-177035 A Japanese Patent Laid-Open No. 06-042160

By the way, the following problems (a), (b), and (c) exist in the baseboard that has been conventionally used.
(A) Construction of baseboard As a baseboard construction method, a resin sheet is attached to the front of the baseboard (R surface) along the front of the baseboard (R surface), or the baseboard In some cases, paint may be applied from above.
When a resin sheet is bonded to a baseboard, the rigidity of the sheet itself varies depending on the sheet thickness, sheet shape, and sheet material, and the sheet has a high rigidity (hard to deform) or a low rigidity (deforms). There is a sheet).
For example, a vinyl chloride resin sheet widely used as a flooring material has a relatively high rigidity, so the sheet of the flooring material is continued from the floor surface as it is, and mortar or the like is applied to the front surface (R surface) of the baseboard. When using and adhering, depending on the shape of the front of the baseboard, the sheet does not adhere well to the front of the baseboard, making it easier for the sheet to peel off, and it takes time for the craftsman to attach the sheet, which takes time, etc. A problem occurs.
In addition, the shape of the upper end and lower end of the conventional baseboard has a U-shaped cross section, so dust and dust tend to accumulate on the flat surface of the upper end, which adversely affects sheet adhesion and paint coating. There is a possibility of effect.
(A) Baseboard material Conventionally used baseboards are made of resin or metal because of their good workability. However, many of the buildings in which baseboards are used mainly have a large total area such as markets, factories, and medical institutions, and because they are fireproof buildings or semi-fireproof buildings, resin baseboards that are not incombustible materials are The problem that it cannot be used arises. In addition, metal baseboards are not suitable for places where a large amount of liquid such as cleaning liquid or water is used due to durability problems such as rust. In addition, when the material is a metal when installed in a freezer, the baseboard itself has a low temperature because of its high thermal conductivity, and heat is transferred to the wall surface or floor surface in contact with the baseboard. Therefore, it is considered to use a composite material using a cement having heat resistance and a low thermal conductivity and low thermal expansion coefficient as a material for the baseboard.
However, the composite material containing cement is likely to be cracked or cracked due to an external impact depending on the component and blending amount of the material. Baseboards are mainly used in markets, factories, medical institutions, etc., and are installed at the intersections where the bottom of the wall and the floor intersect, so there are often collisions between the wheels of the carriage, cleaning brushes, vacuum cleaners, etc. Therefore, there is a demand for a baseboard having improved impact resistance, and selection of the composition of the composite material used as the baseboard and examination of the blending amount are the most important issues.
(C) Use as a protective member In the fish market, food factories, medical institutions, etc., carts are used because they often carry large quantities of food and large quantities of pharmaceuticals. Although the cart has the advantage of being able to carry a large amount of luggage at one time, it is difficult to handle and the cart could hit the wall and damage the surface of the wall.
Conventional skirting boards are installed at the intersections of walls and floors, so if a cart wheel or vacuum cleaner hits the wall near the floor surface, the skirting board will be a protective material to prevent damage to the walls However, when a truck bed collides with a wall at a position away from the floor surface, the wall surface is not covered with baseboard, and the wall surface is damaged or chipped. Will occur.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a baseboard, a sheet with a baseboard, and a floor and wall decoration structure capable of easily and accurately bonding a sheet to an intersection where the bottom of the wall and the floor intersect. The purpose is to do.
Another object of the present invention is a baseboard excellent in heat resistance, impact resistance, frost damage resistance, and water resistance, which are various characteristics required as a baseboard, and is a noncombustible material for a fireproof building or a semi-fireproof building It aims at providing the baseboard which can be used suitably as.
And the objective of this invention aims at providing the baseboard which can protect a wall, even when the loading platform of a trolley collides.

The present invention relates to a baseboard for adhering a sheet used from above or being coated from above, which is attached to an intersection where the bottom of the wall and the floor intersect, and used as a flooring material, It contains cement, siliceous powder, aggregate and fiber as main components, strength attenuation rate is 10% or less, thermal expansion coefficient is 1.0-15.0 × 10 ⁻⁶ / ° C., impact strength is 0 .8 to 25.0 kJ / m ² and thermal conductivity is 0.3 W / mK or less.
According to the present invention, the main components include cement, siliceous powder, aggregate and fiber, the strength attenuation rate is 10% or less, and the thermal expansion coefficient is 1.0 to 15.0 × 10 ⁻⁶ / ° C. When the impact strength is 0.8 to 25.0 kJ / m ² and the thermal conductivity is 0.3 W / mK or less, a baseboard having heat resistance, impact resistance, and frost damage resistance can be obtained. It becomes possible.
The material used as the baseboard is not deformed even when the temperature changes, such as when used in cold regions, when the room where the baseboard is used becomes hot in summer, or when a fire breaks out. It is important that the strength is constant. If the strength attenuation rate of the baseboard is greater than 10%, the baseboard strength will decrease drastically when the temperature drops or rises in cold regions or summer, and it may be lost due to the impact of a vacuum cleaner or bogie wheel. It will break. If the strength attenuation rate of the baseboard is 10% or less, it is possible to obtain a baseboard with excellent heat resistance required as a baseboard, and it can be used for many years in cold districts and high temperature rooms. Become.
In addition, when the temperature changes in a room or the like, the mixed material having cement generally expands due to a change in temperature, and thus the mixed material may crack. When the thermal expansion coefficient of the baseboard is greater than 15.0 × 10 ⁻⁶ / ° C., the baseboard is vulnerable to temperature changes, and cracks occur in the baseboards due to rapid changes in temperature in cold regions and summertime. Since the coefficient of thermal expansion of the cement is 1.0 × 10 ⁻⁶ / ° C., 1.0 × 10 ⁻⁶ / ° C. is the minimum value for the coefficient of thermal expansion of the baseboard. By setting the thermal expansion coefficient of the baseboard to a range of 1.0 to 15.0 × 10 ⁻⁶ / ° C., even when a temperature change occurs, the expansion due to heat is suppressed, and the width of the baseboard is changed by a general indoor temperature change. It is possible to prevent the wood from cracking.
Furthermore, if the thermal conductivity of the skirting board is 0.3 W / mK or less, even when the skirting board becomes hot, it is possible to minimize the transfer of heat to the wall surface and floor surface in contact with the skirting board. Thus, it can be suitably used as a non-combustible material for fireproof buildings. When the thermal conductivity of the baseboard is larger than 0.3 W / mK, heat is transferred to the wall surface and the floor surface, which is unsuitable as a nonflammable material.
In addition, by setting the impact strength of the baseboard to 0.8-25.0 kJ / m ² , even if the corner of the carriage bed, the wheels, the cleaning brush, etc. collide, it will not be broken or broken. It is possible to provide a baseboard having improved impact resistance, and it can be used as a protective material for protecting the wall surface. When the impact strength of the baseboard is less than 0.8 kJ / m ^{2, the} baseboard may be easily broken by the impact of the collision object. Moreover, the maximum value of the impact strength of a baseboard becomes 25.0 kJ / m < ² > from the characteristic of the material used for the baseboard.

The baseboard of the present invention is characterized in that the water absorption is 40% or less.
A composite material containing cement generally easily absorbs moisture, and the absorbed moisture freezes inside the composite material in a place where the temperature is low, such as in a cold district. If the water absorption rate is greater than 40%, the solidified water expands, and cracks such as cracks are generated in the composite material.
According to the present invention, by setting the water absorption rate of the baseboard to 40% or less, it is possible to minimize the expansion of moisture absorbed at a low temperature and to have excellent frost damage resistance that can be suitably used even in cold regions. A baseboard can be provided.

The present invention is also characterized in that the volume change rate is 10% or less when the baseboard is immersed in water and repeatedly frozen and melted.
The baseboard of this application is assumed to be mainly used in markets, factories, medical institutions, etc., and in such places, rain invades and uses a large amount of liquid and water such as cleaning liquid, Water resistance is very important as a baseboard characteristic because it is considered that the baseboard will be submerged. Also, the composite material containing cement is easy to absorb moisture. When used, water absorbed by the baseboard repeatedly freezes and thaws. If the volume change rate when the freezing and thawing are repeated is larger than 10%, there arises a problem that the surface of the baseboard peels off or cracks occur.
According to the present invention, when the baseboard is immersed in water, and the volume change rate when repeated freezing and thawing is 10% or less, it is peeled off even when used in a place where the temperature changes drastically. It is possible to provide a baseboard having a constant strength and excellent water resistance without causing cracks or cracks.

The baseboard of the present invention contains, as main components, 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. It is characterized by.
According to the present invention, a mixture containing 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 fiber is formed and cured. Therefore, it is possible to provide a baseboard that is excellent in heat resistance, impact resistance, frost damage resistance, and water resistance and can be suitably used as a non-combustible material for a fireproof building or a semi-fireproof building. .

The baseboard of the present invention is a baseboard for adhering or coating from above a sheet that is attached to an intersection where the bottom of the wall and the floor intersect and is used as a flooring material. The wood has a curved surface provided in front, the shape of the baseboard is axisymmetric, the upper end and lower end of the baseboard are gradually reduced in thickness toward the tip, and the cross section is R It is a shape.
Here, the “front” of the baseboard is a surface that is exposed to the surface without being hidden by the wall surface and the floor surface when the baseboard is attached to an intersection where the bottom of the wall surface and the floor surface intersect.
The “upper end” of the baseboard is the vicinity of the boundary between the front face and the wall surface of the baseboard and the upper end of the part attached to the wall surface of the baseboard, assuming a bonding surface for bonding the sheet from above the baseboard. An area that is surrounded by the upper end area of the plane or curved surface, the upper face, and the upper end area of the back face.
The “bottom edge” of the baseboard is the area around the boundary between the front and the floor of the baseboard, assuming the adhesive surface that bonds the sheet from the top of the baseboard. Is an end region on the side opposite to the wall surface, and refers to a region surrounded by an end region on the side opposite to the wall surface among the lower end region, the lower surface, and the bottom surface of the curved surface.
According to the present invention, since the curved surface is provided in front of the baseboard, it is easy to attach the sheet from the baseboard after attaching the baseboard to the intersection where the bottom of the wall surface and the floor surface intersect. The sheet can be attached to the sheet, and the sheet is difficult to peel off even after being attached.
Further, according to the present invention, the upper end and the lower end of the baseboard are gradually reduced in thickness toward the tip, so that the boundary between the front and the bottom of the baseboard and the boundary between the front and the bottom of the baseboard The peripheral sheet bonding surface becomes smooth, and even when the sheet is bonded from above the baseboard, a step is hardly generated around the boundary, and the aesthetics are improved. In addition, since the periphery of the boundary is gentle, it is possible to easily and cleanly finish the periphery of the boundary, which requires the most technology when adhering the sheets cleanly. The same applies to the case of painting from the baseboard. Since the boundary area is gently formed, the boundary area can be finished beautifully.
Furthermore, according to the present invention, since the cross-sections of the upper end portion and the lower end portion of the baseboard are R-shaped, dust and dust are less likely to collect at the upper end portion and the lower end portion of the baseboard, and the sheet can be bonded well. Can be painted with paint.
According to the present invention, since the baseboard has a line-symmetric shape, the manufacture is simplified and the baseboard can be manufactured easily and inexpensively.
Furthermore, according to the present invention, when the axis of symmetry between the wall surface and the floor surface is T in the cross-sectional view of the wall surface and the floor surface, the baseboard is similarly shaped to be line symmetric with respect to the symmetry axis T. Therefore, it is possible to stably attach the baseboard at the intersection where the lowermost part of the wall surface and the floor surface intersect, and even if the sheet is attached from above the baseboard, the baseboard does not shift.

The baseboard of the present invention is a baseboard that is attached to an intersection where the lowermost part of the wall surface and the floor surface intersect, and is used for bonding or coating a sheet used as a flooring material from above, The baseboard is provided with a flat surface provided at the upper part of the front surface and a curved surface provided at the lower part of the front surface. The upper and lower ends of the baseboard are gradually reduced in thickness toward the tip and the cross section is R-shaped It is characterized by being.
According to the present invention, the front surface of the baseboard is provided with a flat surface provided in the upper front portion and a curved surface provided in the lower front portion. It is important to gradually increase the front angle (tilt angle) of the baseboard relative to the floor surface in order to properly curve the sheet used in the flooring material using the baseboard, And how to increase the angle of inclination (the angle of the front of the baseboard with respect to the floor) is the most important. Therefore, in order to properly curve the sheet attached to the floor surface from the floor surface to the wall surface, a curved surface is provided in the lower front part of the baseboard and an inclination angle (the angle of the front face of the baseboard relative to the floor surface) is first set. ) While keeping the rate of increase constant, and then at the place where the sheet is sufficiently curved (the point where the shape changes from a curved surface to a flat surface) The inclination angle (the angle of the front surface of the baseboard with respect to the floor surface) is made constant (the increase rate of the inclination angle is set to 0) so that it follows the wall surface. If the front shape of the baseboard is determined in this way, the sheet can be appropriately mounted on the baseboard without causing a gap between the front face of the baseboard and the sheet.
Further, according to the present invention, the upper end and the lower end of the baseboard are gradually reduced in thickness toward the tip, so that the boundary between the front and the bottom of the baseboard and the boundary between the front and the bottom of the baseboard The peripheral sheet bonding surface becomes smooth, and even when the sheet is bonded from above the baseboard, a step is hardly generated around the boundary, and the aesthetics are improved. In addition, since the periphery of the boundary is gentle, it is possible to easily and cleanly finish the periphery of the boundary, which requires the most technology when adhering the sheets cleanly. The same applies to the case of painting from the baseboard. Since the boundary area is gently formed, the boundary area can be finished beautifully.
Furthermore, according to the present invention, since the cross-sections of the upper end portion and the lower end portion of the baseboard are R-shaped, dust and dust are less likely to collect at the upper end portion and the lower end portion of the baseboard, and the sheet can be bonded well. Can be painted with paint.

The baseboard of the present invention further includes a back surface that contacts the wall surface, and the plane is inclined downward at an inclination angle of 27 degrees with respect to the back surface.
The inclination angle of the plane is most suitably 27 degrees, but the inclination angle of the plane may be in the range of 10 degrees to 30 degrees. If the inclination angle of the plane is smaller than 10 degrees, the angle of the connecting position between the baseboard and the curved surface becomes steep, and it becomes difficult to bond the sheet at the connecting position between the baseboard and the curved surface. On the other hand, if the inclination angle of the plane is larger than 30 degrees, the angle of the connecting position between the plane of the baseboard and the curved surface becomes large and loose. In addition, since the angle of the boundary position between the front surface of the baseboard and the wall surface and floor surface of the baseboard at the upper and lower ends of the baseboard becomes steep, it becomes difficult to bond the sheet at the boundary position this time. Therefore, the plane inclination angle is preferably in the range of 10 degrees to 30 degrees, and 27 degrees is more suitable.
The baseboard of the present invention is characterized in that the curved surface is formed with a curved surface having an arc shape in the width direction from above to below, and the radius of the arc shape is 50 mm.
The radius of the curved arc shape is most preferably 50 mm, but the radius of the curved surface may be in the range of 35 mm to 60 mm. If the radius of the curved surface is smaller than 35 mm, the increasing rate of the inclined angle of the curved surface (the angle of the curved surface of the baseboard with respect to the floor surface) increases, so that the inclined angle of the curved surface becomes steep and the sheet is difficult to bend. Conversely, if the radius of the curved surface is greater than 60 mm, the rate of increase in the angle of inclination of the curved surface (the angle of the curved surface of the baseboard with respect to the floor surface) decreases, so the angle of inclination of the curved surface becomes gradual and the sheet is curved on the curved surface. However, the angle becomes steep at the connecting position between the curved surface and the flat surface, and the sheet becomes difficult to bend.
According to the present invention, in a sheet used for a floor surface material, a material having excellent shock absorption and anti-slip properties such as soft vinyl chloride resin, foamed soft vinyl chloride resin, or a combination thereof, and having good drainage is used. Yes. Considering the rigidity of the floor material of the above-mentioned material, the plane is inclined with an inclination angle of 27 degrees downward with respect to the back surface and / or the radius of curvature of the curved surface which is an arc shape of the curved surface is 50 mm. When a baseboard is used, the sheet does not float from the front of the baseboard, and the sheet can be favorably curved.

The baseboard of the present invention includes a chamfered portion for being appropriately attached to the intersection.
According to the present invention, since the baseboard is provided with a chamfered portion, there is a gap at the intersection where the lowest part of the wall surface Q and the floor surface P intersect, the angle is not appropriate, or the surface of the joint Even if there is a problem such as being distorted, a baseboard can be appropriately attached to the intersection.

The baseboard of the present invention is characterized in that no cavity is provided in the baseboard.
Conventionally, if there are cavities inside the baseboard, water accumulates in the cavities, and the baseboard, the walls around the baseboard, the floor and the floor are corroded. According to the present invention, since no hollow is provided in the baseboard, durability of the baseboard, the wall, and the floor is improved, generation of pests can be suppressed, and hygiene can be maintained.

According to the present invention, the cross-sectional shape of the cavity is formed by reducing the shape of the outer surface of the baseboard so that the thickness from the outer surface of the baseboard to the cavity is uniform, It is also possible to form so that there is no change in strength depending on the position, and it is possible to prevent the load from being concentrated on a part of the baseboard 20.
And according to this invention, it is also possible to provide a fine unevenness | corrugation in the whole outer surface of a baseboard, and it is also possible to improve the adhesiveness of a baseboard and a floor surface, a wall surface, and a sheet | seat by a recessed part and an unevenness | corrugation.

The baseboard according to the present invention includes a baseboard body having a curved front surface provided at a lower portion, and a protection portion for absorbing an impact applied when a carriage or the like collides with the wall surface, and the protection portion is the baseboard. It is characterized by being provided continuously upward from the wood body.

In places where baseboards are used in fish markets, food factories, medical institutions, etc., carts with wheel diameters of 75 mm, 100 mm, and 130 mm are often used, and the height of the loading platform is about 125 mm to about 200 mm. Even if various loading platforms are used by setting the height of the baseboard to 200 mm or more, the loading platform can collide with the protection portion and protect the wall surface.
The baseboard needs to be strong enough not to be broken or damaged even if the carrier of the carriage collides. Therefore, by setting the thickness of the baseboard (length in the width direction) to 15 mm or more, it is possible to have a strength that does not cause damage even if the carrier of the carriage collides.

The baseboard of the present invention is characterized by being divided into a plurality of layers in the vertical direction.
Since the baseboard of the present invention is provided with a protection portion for absorbing an impact applied from an impact object, the baseboard has a shape extending upward, and may be heavier than a general baseboard. Therefore, by dividing the baseboard into a plurality of layers, specifically, the baseboard body and the protection part, and the baseboard body and the first protection part and the second protection part, it becomes possible to facilitate transportation.
Further, according to the present invention, the baseboard is assumed to be composed of a plurality of layers of the baseboard body (lowermost layer member) and other layer members (protection part, first protection part, second protection part). In consideration of the height of an impacting object such as a cargo bed of a truck, it is possible to select two-stage lamination or three-stage lamination.

The baseboard of the present invention comprises a baseboard body that is in contact with the floor surface, and one or more protective parts stacked on top of the baseboard body, and the height of the baseboard body is greater than the protective part. It is characterized by that.

The other layer member was stacked on the lowermost layer member by forming the height of the lowermost layer member that is the baseboard body larger than the other layer member that is the protective part, the first protective part, and the second protective part. Even in this case, the stability of the entire baseboard can be improved without breaking the lowermost layer member and the lower layer member due to gravity or vibration.
Further, when the baseboard is composed of three or more layers, the height of the member is increased as the member is closer to the floor (height of the baseboard body> height of the first protection portion> second protection. The height of the part) can improve the stability of the baseboard.

Here, the “decorative structure of floor and wall” refers to a decorative structure composed of a baseboard, a sheet, a panel, and a joint material, which are members used for decorating the floor and wall in the interior of a building. .
Conventionally, by filling a filler such as a caulking material or a sealing material between the panel and the sheet, the airtightness and waterproofness around the intersection of the wall surface and the floor surface are maintained. However, fillers such as caulking materials and sealing materials are susceptible to aging due to their weakness against heat and temperature, and the aesthetics are impaired because the filler is exposed on the surface.

It is a region surrounded by the chamfered portion 13 that connects the end portion and the lower end portion of the back surface 14, and the thickness gradually decreases toward the lower end (tip end). The curved surface 19 is formed with a curved surface having an arc shape in the width direction D from the upper side to the lower side, and extends in the longitudinal direction D. The radius R of the arc shape is most preferably 50 mm, but the radius R may be in the range of 35 mm or more and 60 mm or more, and can be appropriately selected depending on the rigidity of the sheet 100 to be bonded from above the baseboard 10.
Further, the upper end portion of the curved surface 19 is connected to the flat surface 18 in a smoothly continuous state, and the lower end portion of the curved surface 19 is connected to the lower surface 17.
The bottom surface 15 is planar and extends in the longitudinal direction C, and the length in the width direction F is about 37 mm.
The lower surface 17 connects the lower end portion of the curved surface 19 and one end portion of the bottom surface 15, and has a gentle R-shaped curved surface.
The chamfered portion 13 is chamfered with respect to the baseboard 10 in order to appropriately attach the baseboard 10 to the intersection. The joint at the intersection where the bottom of the wall Q intersects the floor P has gaps, an angle is not appropriate, or the surface of the joint is distorted. 10 may not be attached. Therefore, the chamfered portion 13 is provided on the baseboard 10, the wall surface Q and the back surface 14 are brought into contact with each other, and the floor surface P and the bottom surface 15 are brought into contact with each other. It is designed to be properly attached to the location.

The length of the baseboard 10 in the longitudinal direction C is about 450 mm to about 900 mm, but can be appropriately selected depending on the length of the wall surface Q or the floor surface P.

The sheet 100 is a sheet-like floor surface material that is bonded from above the baseboard (FIG. 1), and is attached to the floor surface where rain enters or a large amount of liquid such as cleaning liquid or water is used. It is made of the most suitable material. Specifically, a material that is excellent in shock absorption and anti-slip properties, such as soft vinyl chloride resin, foam soft vinyl chloride resin, or a combination thereof, and has good drainage is used. The sheet 100 has a thickness of about 4 mm.
The panel 200 is a wall decorative panel used for the interior of a building, and has a wide plate shape. The upper surface of the wall surface Q, specifically, the paper surface than the position where the baseboard 10 is attached to the wall surface Q. It is attached to the upper upper part (FIG. 1). The panel 200 can be made of various materials such as a resin material such as hard polyvinyl chloride resin and acrylic resin, an inorganic material, or a combination thereof.
In addition, the sheet 100 and the panel 200 are approximately the same in thickness in consideration of aesthetics.
The joint material 300 is a member that connects the sheet 100 and the panel 200, has a cross-sectional H shape, and is formed by extrusion using a resin or aluminum material. The sheet 100 and the panel 200 are joined without using a filler such as a caulking material or a sealing material by sandwiching the panel 200 and the sheet 100 in the grooves 300a and 300b facing each other. The joint material 300 maintains waterproofness and airtightness between the panel 200 and the sheet 100, eliminates problems such as aging and aesthetics that occur when a filler is used, and the thickness of the sheet 100 and the panel 200. Are formed in substantially the same manner, it is possible to show the joints clearly.

The base material includes cement, siliceous powder, aggregate, and fiber as main components, and is formed of the material as a non-combustible material.
A skirting board mixes each said component by a suitable compounding ratio (mixing process), knead | mixes an appropriate amount of water (kneading process). The kneaded mixture is supplied to an extruder and extruded to obtain an extruded product (extrusion process). Thereafter, the obtained extruded body is cured and dried to obtain a baseboard (curing / drying step).
The baseboard may be integrally formed by extrusion molding, or the planar member 11 and the curved member 12 may be separately formed and joined.

  Examples of cement include hydraulic cements such as normal, early strength, high-temperature, low heat, sulfate-resistant portland cement, belite-rich cement, alumina cement, blast furnace cement, fly ash cement, various mixed cements, etc. 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.

  The siliceous powder is a component used for improving the waterproof function of the baseboard, and includes silica, diatomaceous earth, microsilica, silica fume and the like, and particularly, silica is preferable. 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. When the blending ratio of the siliceous powder is less than 20% by mass, a waterproof effect cannot be obtained, and when the blending ratio of the silicic powder is larger than 41% by mass, the strength of the baseboard is lowered.

  Aggregate is a component used for suppressing heat generation and contraction during curing, and examples thereof include sand, fly ash balloon, shirasu balloon, pearlite balloon, obsidian balloon, perlite, vermiculite, kanamite, and glass microballoon. The blending ratio of the aggregate is in the range of 8 to 31% by mass, and more preferably in the range of 12 to 26% by mass. If the blending ratio of the aggregate is less than 8% by mass, an appropriate heat generation and suppressing effect cannot be obtained.

  Fiber is a component used to reinforce frost damage resistance, such as preventing cracking of baseboard and improving bending strength. Organic fibers such as pulp, waste paper, polyamide fiber, polyester fiber, polypropylene fiber, vinylon fiber, and glass fiber And inorganic fibers such as carbon fiber, and pulp is particularly preferable. The compounding ratio of the fibers is in the range of 2 to 11% by mass, and more preferably in the range of 2.5 to 8% by mass. When the blending ratio of the fibers is less than 2% by mass, appropriate effects such as prevention of cracking and improvement of bending strength cannot be obtained, and when the blending ratio of the fibers is more than 11% by mass, the strength of the baseboard is lowered.

The baseboard obtained by mixing the above components at 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 thermal expansion coefficient 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 It is preferable that the water absorption is 0.3 W / mK or less and the water absorption is 40% or less. Moreover, it is preferable from the point which is excellent in water resistance and frost damage resistance if the volume change rate when a baseboard is immersed in water and it freezes and melt | dissolves repeatedly is 10% or less.

FIG. 8 is a schematic cross-sectional view showing a baseboard mounting structure according to the first embodiment of the present invention.
When the baseboard 10 is attached to the intersection and the sheet 100 is bonded from above the baseboard 10, an adhesive member such as mortar is applied to the intersection where the bottom surface of the wall surface Q and the floor surface P intersect, And the back surface 14 of the baseboard 10 are brought into contact with each other, the floor surface P and the bottom surface 15 of the baseboard 10 are brought into contact with each other, and the baseboard 10 is attached to the intersection.
Thereafter, the joint material 300 is fixed to an appropriate portion of the wall surface Q using a double-sided tape.
Next, the sheet 100 is bent along the curved surface 19 of the baseboard 10, brought into contact with the flat surface 18 of the baseboard 10, and the sheet 100 is attached from the floor surface P to the wall surface Q. A curved surface 19 is provided in the lower front portion of the baseboard 10 and the sheet 100 is first curved while keeping the rate of increase in inclination angle (the angle of the front face of the baseboard relative to the floor) constant, and then the sheet 100 is sufficiently At a curved portion (a point at which the shape changes from the curved surface 19 to the flat surface 18), the inclination angle (the front surface of the baseboard 10 with respect to the floor surface P as a reference) on the flat surface 18 provided at the upper front of the baseboard 10 The angle) is constant, and is along the wall surface Q. Here, if the radius R of the arcuate shape of the curved surface 19 of the baseboard 10 is too small, the sheet 100 does not come into good contact with the curved surface 19 of the baseboard 10 and floats. If the inclination angle θ of the plane 18 as a reference is too small, a phenomenon occurs in which the sheet 100 does not come into good contact with the plane 18 of the baseboard 10 and floats. However, by appropriately selecting the radius R of the arc shape of the curved surface 19 of the baseboard 10 and the inclination angle θ of the flat surface 18 of the baseboard 10, the curved surface 19 and the flat surface 18 of the baseboard 10 and the sheet 100 are interposed between them. The phenomenon that the floating occurs is eliminated, and the sheet can be adhered to the baseboard 10 in close contact.
Then, by sandwiching the upper part of the sheet 100 between the grooves 300b of the joint material 300, the joint material 300 and the sheet 100 are joined with an adhesive or the like.
Finally, the panel 200 is attached to the upper portion of the wall surface Q, the lower portion of the panel 200 is sandwiched in the groove 300a of the joint material 300, and the joint material 300 and the panel 200 are joined with an adhesive or the like.
Here, the panel 200 is applied to the wall surface Q after the sheet 100 is attached to the wall surface Q and the floor surface P. However, after the panel 200 is applied to the wall surface Q, the sheet 100 may be attached to the wall surface Q and the floor surface P.
The above-described attachment method is an attachment method in which the sheet 100 is attached to the intersection of the wall surface Q and the floor surface P using the baseboard 10, but in the case of painting, the coating is applied to the lower end of the joint material 300 to which the wall surface is fixed. If the coating is applied up to the groove of the joint material 300, the coating becomes difficult to peel off.

When the baseboard 10 of the present embodiment is used, even if there is a problem such as a gap at the junction between the lowermost part of the wall surface Q and the floor surface P, the chamfered portion 13 exists, so The seat 100 can be appropriately attached at the intersection where the lower portion and the floor surface P intersect, and the radius R of the curved surface 19 of the baseboard 10 and the inclination angle θ of the plane 18 are appropriately selected. Can be appropriately bonded to the baseboard 10.
Furthermore, since the thickness of the upper end portion and the lower end portion of the baseboard 10 is gradually reduced toward the tip, sheet adhesion around the boundary between the front surface of the baseboard 10 and the wall surface and the boundary between the front surface of the baseboard and the floor surface is performed. Even when the sheet 100 is bonded from above the baseboard, the surface becomes gentle and a step is hardly generated around the boundary, so that the aesthetics are improved. Further, since the periphery of the boundary is gentle, it is possible to easily and cleanly finish the periphery of the boundary, which requires the most technology when the sheet 100 is adhered beautifully.
And since the cross section of the upper end part and lower end part of the baseboard 10 is carrying out R shape, it is hard to collect dust and dust on the upper end part and lower end part of the baseboard 10, and adhere | attaches the sheet | seat 100 well, such as paint Can be painted.

The baseboard 20, which is another example 1 of the first embodiment, has a hollow 21 formed inside the baseboard 20 in order to reduce the weight of the baseboard 20.
The cross-sectional shape of the cavity 21 is a shape obtained by reducing the shape of the outer surface of the baseboard 20, and is formed in a long shape along the longitudinal direction C. By forming so that the thickness from the outer surface of the baseboard 20 to the cavity 21 is uniform, it is formed so that there is no change in strength depending on the position of the baseboard 20, and the load is not concentrated on a part of the baseboard 20 It was devised as such.

Further, the baseboard 30 which is another example 2 of the first embodiment has a plurality of recesses 31 and 31 formed on the back surface 14 and / or the bottom surface 15 of the baseboard 30 in order to reduce the weight of the baseboard 30. Is.
The recesses 31, 31 are depressions having a rectangular cross section provided in the back surface 14 and / or the bottom surface 15, and are formed in a long shape along the longitudinal direction C. Even if the recesses 31, 31 are provided on the back surface 14 and / or the bottom surface 15, the structure becomes a rib structure, and the strength of the baseboard 30 itself does not decrease.
The cross-sectional shape of the recesses 31, 31 is rectangular, but it may be arcuate or triangular. The number of the recesses 31 provided on the back surface 14 and / or the bottom surface 15 is two on the back surface 14 and one on the bottom surface 15 in the embodiment, but the number can be appropriately selected.
Further, it is possible to provide fine unevenness 32 (not shown) on the entire outer surface of the baseboard 30. The concave portions 31, 31 and the unevenness 32 can reduce the weight, and the baseboard 30 and the floor surface can be reduced. Adhesiveness with P, wall surface Q and sheet is improved.
Here, the cavity 21 provided in the baseboard 20 and the recesses 31 and 31 and the unevenness 32 of the baseboard 30 can be provided in common, and if the cavity 21 is present inside the baseboard, the cavity 21 is provided. If there is a concern that water will accumulate inside or a habitat for pests, it is also possible not to actively provide a cavity inside the baseboard.

(Second Embodiment)
FIG. 6 is a cross-sectional view showing a baseboard according to the second embodiment of the present invention. The baseboard 40 of the second embodiment simplifies the manufacture of the baseboard 40 by making the shape of the outer surface simpler than the baseboard 10 of the first embodiment. It can be installed more stably at the intersection where the lowermost wall surface Q and the floor surface P intersect. Other configurations are the same as those of the first embodiment, and thus redundant description is omitted.

The baseboard 40 of the present embodiment includes a curved surface 49 provided on the front surface, a back surface 44 that contacts the wall surface Q, an upper surface 46 that connects the upper end of the curved surface 49 and the back surface 44, and a bottom surface that contacts the floor surface P. 45, a lower surface 47 connecting the lower end portion of the curved surface 49 and one end portion of the bottom surface 45, and a chamfered portion 43 connecting the other end portion of the bottom surface 45 and the lower end portion of the back surface 44. Yes, the thickness gradually decreases toward the upper and lower ends (tips). Further, it has a line-symmetric shape with respect to the symmetry axis T (FIG. 6), and this symmetry axis T is the same as the symmetry axis between the wall surface Q and the floor surface P in the sectional view of the wall surface Q and the floor surface P. It is.
The curved surface 49 is formed with a curved surface having an arc shape in the width direction D from above to below, and extends in the longitudinal direction D. The radius R of the arc shape is most suitably 50 mm, but the radius R may be in the range of 35 mm to 60 mm, and can be appropriately selected depending on the rigidity of the sheet 100 to be bonded from above the baseboard 10.
The bottom surface 45 is planar and extends in the longitudinal direction C, and the length in the width direction F is about 20 mm.
The back surface 44 is also planar and extends in the longitudinal direction C, and the length in the width direction E is about 20 mm.
The upper surface 46 connects the upper end of the curved surface 49 and the upper end of the back surface 44, and the upper surface 46 is inclined upward with respect to the back surface 44. The inclination angle β is approximately 135 degrees. The upper surface 46 is connected to the upper end of the curved surface 49 in a gentle R shape.
When the upper surface 46 is inclined upward, a filler or mortar such as a coating material or sealing enters the gap between the wall surface Q and the upper surface 46, and the coating material, filler or mortar peels from the wall surface Q. As a result, the sheet 100 can be prevented from floating from the wall surface Q.
The lower surface 47 connects a lower end portion of the curved surface 49 and one end portion of the bottom surface 45, and the lower surface 47 is inclined upward with respect to the bottom surface 45. The inclination angle β is approximately 135 degrees. The lower surface 47 is connected to the lower end of the curved surface 49 in a gentle R shape.
When the lower surface 47 is inclined downward, as in the case of the upper surface 46, a filler or a mortar such as a coating material or a sealing enters the gap between the floor surface P and the lower surface 47, and the coating material and the filler Or it can prevent that mortar peels from the floor surface P, and can prevent that the sheet | seat 100 floats from the floor surface P as a result.
The chamfered portion 43 is chamfered with respect to the baseboard 40 in order to attach the baseboard 40 appropriately at the intersection. The wall surface Q and the back surface 44 are brought into contact with each other, and the floor surface P and the bottom surface 45 are brought into contact with each other, so that the lowermost part of the wall surface Q and the floor surface P are appropriately attached.
The chamfered portion 43 is a planar surface that connects the other end of the bottom surface 45 and the lower end of the back surface 44, and is attached to be inclined from the back surface 44 and the bottom surface 45. Degree. The length in the width direction G of the chamfered portion 43 is about 12 mm.

FIG. 9 is a schematic cross-sectional view showing the baseboard mounting structure of the second embodiment of the present invention.
When the baseboard 40 is attached to the intersection and the sheet 100 is bonded from above the baseboard 40, an adhesive member such as mortar is applied to the intersection where the lowermost surface of the wall surface Q and the floor surface P intersect, The base plate 40 and the back surface 44 of the base plate 40 are brought into contact with each other, the floor surface P and the bottom surface 45 of the base plate 40 are brought into contact with each other, and the base plate 40 is attached to the intersection.
Thereafter, the joint material 300 is fixed to an appropriate portion of the wall surface Q using a double-sided tape.
Next, the sheet 100 is bent along the curved surface 49 of the baseboard 40, and the sheet 100 is attached from the floor surface P to the wall surface Q. Here, if the radius R of the circular arc shape of the curved surface 49 of the baseboard 40 is too small, a phenomenon occurs in which the sheet 100 does not come into good contact with the curved surface 49 of the baseboard 40 and floats. However, by appropriately selecting the radius R of the arcuate shape of the curved surface 49 of the baseboard 40, there is no occurrence of floating between the curved surface 49 of the baseboard 40 and the sheet 100, and the baseboard 40 is in close contact with the baseboard 40. It becomes possible to adhere the sheets.
Then, by sandwiching the upper part of the sheet 100 between the grooves 300b of the joint material 300, the joint material 300 and the sheet 100 are joined with an adhesive or the like.
Finally, the panel 200 is attached to the upper portion of the wall surface Q, the lower portion of the panel 200 is sandwiched in the groove 300a of the joint material 300, and the joint material 300 and the panel 200 are joined with an adhesive or the like.
Here, the panel 200 is applied to the wall surface Q after the sheet 100 is attached to the wall surface Q and the floor surface P. However, after the panel 200 is applied to the wall surface Q, the sheet 100 may be attached to the wall surface Q and the floor surface P.

When the baseboard 40 of the present embodiment is used, even if there is a problem such as a gap at the junction of the intersection where the lowermost part of the wall surface Q and the floor surface P intersect, the chamfered portion 43 exists, so It is possible to appropriately attach to the intersection where the lower portion and the floor surface P intersect, and appropriately select the radius R of the arc shape of the curved surface 49 of the baseboard 40, so that the sheet 100 is appropriately attached to the baseboard 40. It becomes possible to bond, and since the shape of the outer surface is a line symmetrical simple shape, the manufacture of the baseboard 40 is simplified and the baseboard 40 can be easily manufactured.
In addition, since the baseboard is shaped so as to be line symmetric with respect to the axis T similar to the axis of symmetry between the wall surface Q and the floor surface P, the baseboard is more stable at the intersection where the bottom surface of the wall surface Q and the floor surface P intersect. A baseboard can be attached, and even if a seat is attached, the baseboard will not shift.
Further, since the upper end portion and the lower end portion of the baseboard 40 are gradually reduced in thickness toward the tip, sheet adhesion around the boundary between the front surface of the baseboard 40 and the wall surface and the boundary between the front surface of the baseboard and the floor surface is performed. Even when the sheet 100 is bonded from above the baseboard, the surface becomes gentle and a step is hardly generated around the boundary, so that the aesthetics are improved. Further, since the periphery of the boundary is gentle, it is possible to easily and cleanly finish the periphery of the boundary, which requires the most technology when the sheet 100 is adhered beautifully.
And since the cross section of the upper end part and lower end part of the baseboard 40 is carrying out the R shape, it is hard to collect dust and dust on the upper end part and lower end part of the baseboard 40, adhere | attaches the sheet | seat 100 well, paints, etc. Can be painted.
