Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a siding panel used for an existing or new detached house, an apartment house, and an outer wall panel using the same.

[0002]

2. Description of the Related Art Conventionally, siding panels used for detached houses and condominiums include embossed metal siding materials having hard urethane foam, gypsum board, and phenol foam as core materials, ceramic tiles, and natural stones. Tones such as ceramic-based siding materials, exterior wall materials made of wet mortar with ricin, and ceramic tiled exterior wall materials are generally used. Of these, ceramic tile siding and natural stone-grained ceramic siding are widely used because of their excellent design.

[0003]

However, the above-mentioned conventional siding panel has the following problems.

That is, in recent years, ceramic siding materials have been shifting to the direction of deep embossing in order to further enhance the designability and sense of quality, and the thickness of the plate has been increasing.
As a result, the design and luxuriousness are satisfied, but the siding material for ceramics deteriorates the workability due to the increase in cost, increase in thickness and weight, resulting in an increase in the construction cost and pressure measures. Have been. At present, there is also a need for insulation measures to meet the new energy conservation standards. Furthermore,
Even when renovating the outer wall of an existing house, it is difficult to apply the existing outer wall on the existing outer wall due to the increase in thickness and weight, and it is also necessary to take measures to reinforce the foundation of the outer wall of the existing house.
This leads to an increase in construction costs, and measures to reduce costs are an important issue for dissemination as exterior wall reforms.

[0005] Further, metal siding made of hard urethane foam as a core material is flammable and lacks fire resistance, so that it cannot be used legally for outer walls and renovation walls of new or existing houses in fire-protected areas.

[0006] Further, with respect to metal siding materials using hard urethane foam as a core material, fireproofing is an important issue, and metal siding using non-combustible phenol foam as a core material is shifting to non-combustible phenol foam. In order to widely spread metal siding using as a core material, price measures have become necessary.

Further, metal siding materials using gypsum board as a core material lack heat insulation and waterproofness, and are decreasing year by year.

[0008] Further, the outer wall material obtained by applying lysine decoration to a wet mortar and the outer wall material attached with a ceramic tile are decreasing year by year due to quality problems such as cracks and a long construction period. .

The present invention has been made in view of the above circumstances, and has nonflammability, fire resistance, heat insulation, and waterproofness.
It is another object of the present invention to provide a siding panel and an outer wall panel capable of improving workability and reducing costs.

[0010]

In order to achieve the above object, a siding panel according to the present invention embosses a composite board having a surface material mainly containing metal and a backing material made of felt mainly containing inorganic short fibers. An uneven pattern is formed on the surface of the surface material by molding.

According to the present invention, since the felt containing the inorganic short fibers has a suitable heat insulating property, when used as an outer wall material, dew condensation on the back surface of the front material is prevented in winter. In addition, the felt containing inorganic short fibers is a non-combustible material itself, and the siding panel of the present invention has waterproofness and fire resistance because the surface material mainly contains metal. It can be used as a panel for renovating the outer wall of a house. Also, since the surface material is lined with felt, mechanical external force during the embossing process is reduced, so that cracks and wrinkles are reduced in the embossed portion of the surface material, and the surface is deeply embossed. Becomes possible. Therefore, a texture comparable to ceramic siding can be obtained. Furthermore,
Since the siding panel is composed of a backing material made of felt mainly containing inorganic short fibers with a lower specific gravity than the surface material and a composite plate of the surface material, the overall weight is reduced and workability when using the siding panel is improved. I do. Further, when the composite board is embossed, the felt enters the back side of the convex portion of the surface material, so that the siding panel can be thinned. Furthermore, since the felt has flexibility, the felt surface fits the unevenness of the outer wall surface of the existing house (meaning the unevenness of the surface), and the workability can be improved, and the cost can be improved. Down becomes possible.

It is preferable that the siding panel is formed by random multicolor coating on the surface of the surface material. This makes the surface of the siding panel look like ceramic tile,
As a result, it will have a natural stone-grained finish, have a good texture for use as a renovation panel for an existing house and a new house, and have favorable exterior wall panel conditions with excellent design.

[0013] In the above siding panel, the surface material of the composite plate preferably has a thickness of 0.15 to 0.5 mm, more preferably 0.2 to 0.5 mm. In this case, lightness and workability are improved. If the thickness of the surface material is less than 0.15 mm, dents are likely to occur due to external force, and the flatness after construction tends to deteriorate,
If it exceeds 0.5 mm, the material cost is increased, the weight is increased, and the workability tends to deteriorate.

In the siding panel,
The surface material is preferably at least one selected from the group consisting of galvanized steel, resin-coated steel, stainless steel, aluminum, aluminum alloy and copper. By using such a material, compared to the case of using other materials, it is lightweight, has good workability, and has good moldability.

Further, in the above siding panel, the felt constituting the backing material is at least one kind of artificial inorganic short fiber selected from the group consisting of rock wool, glass wool and ceramic wool, and attapulgite, wollastonite and sepiolite. And at least one natural inorganic short fiber selected from the group consisting of
It is preferable that the bulk specific gravity of the felt is 0.2 to 0.6 and the backing material has a thickness of 2 to 10 mm.

If the bulk specific gravity of the felt is less than 0.2, the felt processing is difficult, the tear strength is reduced, the cushioning property is deteriorated, and the surface material tends to be damaged by embossing. If it exceeds 0.6, the cost tends to be high, and the heat insulation tends to decrease. Further, when the thickness of the backing material is less than 2 mm, the unevenness control function, tear strength and sound insulation tend to decrease, and when it exceeds 10 mm, the cost increases, and the weight increases and the workability tends to decrease. is there.

Further, in the siding panel, one of the two edges along the longitudinal direction of the surface material is bent to form a female accommodating portion, and the other edge is an accommodating portion. It is preferable that it is a male edge having a shape that can be fitted into the connector.

In the case where a plurality of siding panels according to the present invention are prepared, the female type accommodating portions at both edges along the longitudinal direction of the surface material of each siding panel are provided with male type siding panels. By accommodating the edge, connection of the plurality of siding panels on the longitudinal direction side of the surface material is facilitated.

Further, in the siding panel, it is preferable that both end portions of the surface material along the lateral direction are L-shaped.

A groove can be formed by preparing a plurality of siding panels according to the present invention and overlapping L-shaped ends of the surface material of each siding panel along the short direction. . Therefore, the groove can be filled with a sealing material or the like, so that water can be prevented from entering between the siding panels, and the design of the siding panel after construction can be enhanced.

In the siding panel, it is preferable that the surface material and the backing material are releasably joined by an adhesive. In this case, in the used siding panel, the surface material and the backing material can be easily separated, and recycling separation can be easily performed at the time of disassembly later.

Further, an outer wall panel according to the present invention includes the above-mentioned siding panel and a base material attached to a backing material of the siding panel, wherein the base material is a mineral fiber board having a bulk specific gravity of 0.5 or less, and a bulk specific gravity of 0. Dry rock wool board of 0.3 or less, wood wool cement board of bulk specific gravity of 1.0 or less, sandwich panel sandwiching rock wool board of bulk specific gravity of 0.5 or less between a pair of wood wool cement boards, bulk specific gravity of 0.3.
Calcium silicate board mixed with fiber of 8 or less, phenol foam board filled with inorganic material having bulk specific gravity of 0.3 or less, bulk specific gravity of 1.0
It is characterized by being selected from the group consisting of the following gypsum slag cement board and gypsum board.

Since the outer wall panel has heat insulation, fire resistance and mechanical strength, it is particularly effective as an outer wall panel of a new house requiring heat insulation, fire resistance and mechanical strength.

[0024]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The siding panel 10 of the present invention is shown in FIG.
As shown in FIG. 1, a composite plate having a surface material 1 mainly containing a metal and a backing material 2 made of felt mainly containing inorganic short fibers is formed by embossing a concave portion 3 and a convex portion 4 on the surface of the surface material 1. It is formed by forming an uneven pattern.

The felt containing inorganic short fibers constituting the backing material 2 of the siding panel 10 of the present invention is backed by the surface material 1 mainly containing metal, so that the mechanical external force at the time of embossing is reduced. Therefore, the occurrence of cracks and wrinkles in the embossed portion of the surface material 1 is reduced, and the surface of the surface material 1 can be embossed, particularly deep embossed. Felt has appropriate heat insulation properties.
It also has the function of preventing condensation on the back surface. In addition, since the felt has flexibility, the felt surface fits the unevenness of the outer wall surface of the existing house, and the workability can be easily set. Furthermore, the felt containing the inorganic short fibers is itself a non-combustible material, and the siding panel of the present invention in which the felt 1 is lined with the surface material 1 can be used as a panel for renovating an outer wall of an existing house in a fire prevention area.

The felt containing inorganic short fibers used in the siding panel of the present invention substantially separates and removes non-fibrillated particles called shots in order to impart incombustibility and fire resistance to a fiber length of 10 mm or less. Felt can be formed into a slurry in the same manner as papermaking by dispersing cut inorganic wool such as rock wool, ceramic wool, glass chopped fiber of 10 mm or less, and glass wool into a slurry.

Here, the felt containing inorganic short fibers used in the siding panel of the present invention will be described in detail.

For the felt of the siding panel of the present invention
Rock wool as an artificial mineral short fiber contained is
It is obtained as follows. That is, first of all, SiO_Two35-55Wt

ing. Granular cotton and fine cotton are raw materials for felt directly.
It is difficult to use the
Used in the form of processed short fibers with the fiber length adjusted by the fiber cutting process.
To use. Such treatment, granular cotton, fine cotton was dispersed in water
Made by pulper, cleaner in state. Like this
And a fiber length of 10 mm or less that does not substantially contain shots.
A processed short fiber type rock wool is obtained.

The mixing ratio of rock wool in the felt is as follows:
The range of 80 to 97 Wt% is preferable in relation to noncombustibility and felt strength. This is because the mixing ratio of rock wool is 80 Wt
%, The non-combustibility tends to be impaired, and if it is 97 Wt% or more, the tensile strength tends to be insufficient.

Ceramic wool which can be used as other artificial inorganic short fibers is obtained as follows. That is, first, 45 to 50 Wt% of SiO _2, 45 to 50 Wt% of Al ₂ O ₃ , and Z
A powdery raw material that becomes a trace component such as rO _{2 at} 0 to ₅ Wt% is melted at a high temperature in an electric furnace, and fiberized by a blowing method or a spinning method using a high-speed rotating body, like rock wool. The fiber shape and shot content obtained at this time are substantially the same as in the case of rock wool, and processed short fibers having a fiber length of 10 mm or less that have been deshot are obtained in the same manner as in rock wool. Thus, the ceramic wool used in the present invention is obtained.

Glass wool is obtained as follows. That is, first _{SiO 2 60~72 Wt%, Al 2} O 3 1~5Wt%,
MgO0~5Wt%, CaO6~11 Wt%, B 2 O 3 0~7Wt%, Na 2 O
+ K ₂ O 14 ~ 19 Wt%, powder raw material consisting of other minor components is melted in an electric furnace, and the melt is centrifugally applied to the high-speed rotating body through pores on the side wall of the high-speed rotating body by vertical spinning or fire method. The fibers are converted to fibers by discharging. Since the fiber thus obtained contains substantially no shots,
It can be used as the glass wool of the present invention in the form of processed short fibers cut to a fiber length of not more than mm.

From the viewpoints of cost reduction, surface smoothness of felt, and heat resistance imparted by artificial high-temperature sintering with artificial inorganic short fibers, attapulgite is used for the above-mentioned artificial inorganic short fibers such as rock wool, ceramic wool and glass wool. It is preferable to blend a small amount of natural inorganic short fibers such as wollastite and sepiolite in a range of 10 Wt% or less. Thus, when natural inorganic short fibers are blended, there is an advantage that fire resistance is improved. Among these natural inorganic short fibers, sepiolite fibers are particularly preferred. this is,
This is because sepiolite fiber is excellent in sinterability and its addition is effective for improving the heat-resistant shape retention of felt.

To the above-mentioned artificial inorganic short fibers and natural inorganic short fibers, small amounts of an organic binder and a binding aid are added in order to impart the flexibility, mechanical strength and water resistance of the felt. Resins used as organic binders include acrylic resins, modified acrylic resins, polyvinyl acetate, ethylene-vinyl acetate copolymer resins, emulsion resins such as polyvinylidene chloride resins, powder resins such as phenol resins and melamine resins, and resins containing inorganic substances. And pulp-like organic binders such as polyethylene pulp. Examples of the heat-fusible organic fiber used as a kind of the organic binder include polypropylene fiber, nylon fiber, and ethylene-propylene composite fiber, and ethylene-propylene composite fiber is particularly preferable.

In addition, since felt is manufactured by a wet papermaking method,
A small amount of a coagulant such as polyacrylamide or sulfuric acid band for effectively holding the organic binder on the felt, or a water repellent such as a wax emulsion or silicone resin emulsion for imparting water repellency to the felt can be added. . The compounding ratio of the organic binder and a small amount of a binding aid such as a coagulant or a water repellent is 2 to 1 in relation to strength and nonflammability.
A range of 0 Wt% is preferred. If the compounding ratio is less than 2 wt%, the non-combustibility is good, but the tear strength tends to deteriorate,
If it exceeds 10 wt%, the tear strength is sufficient, but the nonflammability tends to be impaired.

Further, the above artificial inorganic short fibers and natural inorganic short fibers have a fiber length of 1 due to the papermaking formability of felt.
It is preferable to add organic fibers such as synthetic fibers or cellulose fibers having a diameter of 0 mm or less.

Further, the felt has fire resistance, light weight,
From the viewpoint of cost reduction and the like, it is preferable to mix a small amount of aluminum hydroxide, shirasu balloon, calcium carbonate, and expanded graphite.

The constituents of the inorganic short fiber felt are as described above. The mixture containing the constituents of the felt is dispersed in water, and the mixture is mixed with a papermaking machine such as a circular net type, a long net type, and a rotoformer. The non-combustible and flexible felt is manufactured by making it into a felt and then drying it.
The thickness of the felt is preferably 2 to 10 mm.

On one or both sides of the felt, as a measure for reinforcing the felt, the basis weight is 50 g / m ² or less, preferably 30 g / m ² or less.
It is preferable that a polyester nonwoven fabric is laminated within a range that does not impair the incombustibility of not more than g / m ² , needle punched, and laminated and composited with the surface material 1 via an adhesive in that form. Thereby, the mechanical strength of the felt is further improved,
At the time of embossing, delamination between the surface material 1 and the backing material 2 is sufficiently prevented.

As the surface material 1 of the siding panel of the present invention, for example, galvanized steel, steel coated with a resin such as a vinyl chloride resin, stainless steel, aluminum, an aluminum alloy, copper or the like is preferably used. In addition, from the viewpoint of further preventing the occurrence of cracks, wrinkles, etc. in the embossed portion of the surface of the surface material 1 during deep embossing molding of the surface material 1 of the siding panel, aluminum having good flexibility and good elongation is used. Aluminum alloys are preferred.

The thickness of the surface material 1 is preferably 0.15 to
0.5 mm, more preferably 0.2 to 0.5 mm
It is.

Although the main materials constituting the siding panel of the present invention are as described above, the surface material 1 and the backing material 2 made of felt containing inorganic short fibers are bonded and combined by means such as adhesion. In this adhesive processing, an acrylic resin-based, vinyl acetate resin-based, urethane resin-based, synthetic rubber-based such as SBR / NBR, or epoxy resin-based adhesive is applied to the back side of the surface material 1, and then the felt is applied. It can be performed by pressing and drying as necessary. Here, it is preferable that the adhesive has an adhesive strength such that the surface material 1 and the backing material 2 can be peeled off. In this manner, the surface material 1 and the backing material 2 can be easily separated from the used siding panel, and the surface material 1 and the backing material 2 can be recycled. In order to make the adhesive strength such that the adhesive can be peeled off, for example, at the time of adhesion, the adhesive is adhered to the back side of the surface material 1 in a dot-like manner, and then the backing material 2 may be overlaid.

The composite plate thus obtained is inserted into a pair of male and female press dies in the form of a roll or a plate having a ceramic tile-like or natural stone-like pattern, and press-formed to form the surface material 1. An embossed pattern is formed on the surface. Thus, a concavo-convex pattern is formed on the surface material 1, and the design is imparted.

When the siding panel 10 has a rectangular shape, as shown in FIG. 2, one edge 5a of both edges along the longitudinal direction of the surface material 1 is bent to form a female housing portion. 6 and the other edge 5b is
It is preferable that it is a male edge having a shape that can be fitted into the connector. When a plurality of siding panels 10 having such a configuration are prepared, the surface material of another siding panel 10 is placed in the female accommodating portions 6 at both edges 5a and 5b along the longitudinal direction of the surface material 1 of each siding panel 10. By accommodating the one male edge 5b, it is possible to easily connect the plurality of siding panels 10 to each other. In addition,
As shown in FIG. 5, it is preferable that the tip portion 11 of the edge portion 5a and the tip portion 12 of the edge portion 5b are each folded back by a molding machine such as a roll former to form two sheets. In this case, the connection between the housing portion 6 and the edge portion 5b is reinforced.

The siding material in this processing stage is cut to a required length by a cutter such as a rotating tooth. Both ends of the surface material 1 along the lateral direction are press-formed as in the embodiment described later. It is preferable that the shape be L-shaped (see FIG. 6). With such a structure, when the plurality of siding panels 10 are connected to each other in the lateral direction, the grooves 14 can be formed by overlapping the L-shaped end portions 13 with each other. Therefore, the groove 14 can be filled with the sealing material 15 and the like, so that water can be prevented from entering between the siding panels 10 and the design of the siding panel 10 after construction can be enhanced. Thus, it is processed into a final basic shape as a siding panel.

As a method for providing the siding panel of the present invention with the same design property as that of the ceramic outer wall material, as described above, there is a method of deep embossing the surface material 1, whereby the surface of the surface material 1 is formed. Although a complex and three-dimensional shape is provided and the design is satisfactory, there is a surface makeup method as another means for improving the design. Here, it is difficult to provide a satisfactory design by a conventional coating method in which a single color is repeatedly applied with a means such as a spray or a roll coater to obtain a ceramic tile tone and a natural stone tone tone. Therefore, in order to enhance the design of the siding panel of the present invention, it is preferable to perform random multicolor coating on the surface of the surface material 1 of the siding panel. As the random multicolor coating method, for example, an RS coating (Random select coating) method of Dainippon Paint Co., Ltd. can be used. By performing deep embossing and random multicolor coating in this way, it is possible to finish the siding panel of the present invention to an appearance close to a ceramic tile or a natural stone tone.

Since the siding panel of the present invention falls under the category of noncombustible material (first class flame retardant according to JIS A1321) notified by the Ministry of Construction, it does not impair the fire protection performance even when used as a panel for renovating the outer wall of an existing house. It has the advantage of not being restricted in fire protection areas. Also, since the siding panel is made of a felt backing material 2 containing inorganic short fibers, it is lightweight and has good cutting workability, so that it can be easily installed even when it is attached to an outer wall surface having some unevenness (unevenness). It is suitable as a siding panel for renovation. After the siding panel is attached to the wall of the house, the siding panel has a stone-grained appearance in vertical joints and horizontal joints. Furthermore, joints are sealed to the siding panel with caulking material, and furthermore, by adopting ceramic-type L ground type members at the corners of the outer and outer corners of the outer wall, the design is comparable to that of the ceramic outer wall material. It can be finished to the exterior wall with.

The siding panel of the present invention is generally rectangular, and has a length of 3700 in the longitudinal direction.
~ 4000mm, the length in the short direction is usually 360 ~
380 mm.

Further, when the siding panel of the present invention is used for the outer wall of a newly built house, the outer wall has heat insulation, fire resistance,
Mechanical strength must be provided. In order to satisfy the required performance, as shown in FIG. 3, the siding panel 10 of the present invention is laminated on a base material 8 having light weight, heat insulating property, fire resistance and mechanical strength at a construction site, and This can be achieved by forming the outer wall panel 11 including the siding panel 8 and the siding panel 10. As the base plate 8, for example, a mineral fiber board having a bulk specific gravity of 0.5 or less (a specific example is Fesco board manufactured by Thermal Ceramics Co., Ltd., and a minerala board manufactured by Nitto Boseki Co., Ltd.), and a bulk specific gravity of 0.3 or less Dry rock wool board (hard type manufactured by Rock Wool International, as a specific example), bulk specific gravity 1.
0 or less wood wool cement board (Heracrete M manufactured by Herakleit Co., Ltd. as a specific example), a sandwich panel which is easy to nail at the time of construction where a rock wool board having a bulk specific gravity of 0.5 or less is sandwiched between a pair of wood wool cement boards. As specific examples, Tectalane E manufactured by Herakleit Co., Ltd., a fiber-mixed calcium silicate plate having a bulk specific gravity of 0.8 or less (NA Lux manufactured by Nichias Corporation as a specific example), and an inorganic-filled phenol foam plate having a bulk specific gravity of 0.3 or less ( Specific examples include Firelock DN manufactured by Nitto Boseki Co., Ltd.) and a gypsum slag cement plate or gypsum plate having a specific gravity of 1.0 or less (specific examples include Tiger Glass Rock manufactured by Yoshino Gypsum Co., Ltd.). Such a base material 8 is attached as a base plate 8 to a stud and a rim of a house, and a siding panel 10 of the present invention is placed thereon.
The outer wall of a newly built house can be constructed by stacking and finishing. The thickness of the base material 8 is preferably about 15 to 50 mm from the viewpoint of further improving workability.

When the thickness of the base material 8 is about 25 mm, the outer wall panel 11 passes the fire protection of 30 minutes and the quasi-fire resistance of 45 minutes. When an airtight moisture-proof sheet is stuck on the inner wall side, the siding panel 10 of the outer wall panel 11 is used.
Outer wall ventilation method that forms a ventilation layer between the base material and the base material 8 prevents internal condensation and has excellent durability. Furthermore, the insulation performance conforms to regional energy conservation standards and a design comparable to ceramic exterior wall material. Finish with excellent appearance.

The siding panel of the present invention depends on the surface material 1 to be used.
Lighter weight and better workability compared to ² ceramic outer wall materials
As a result, the workability is excellent, and there is also an advantage that the conventional construction cost can be reduced.

The concrete manufacturing method and performance of the siding panel and the outer wall panel of the present invention, the renovation of an existing house, and the method of constructing the outer wall of a new house will be described with reference to examples.

[Correction contents]

As a method for providing the siding panel of the present invention with the same design property as that of the ceramic outer wall material, as described above, there is a method of deep embossing the surface material 1, whereby the surface of the surface material 1 is formed. Although a complex and three-dimensional shape is provided and the design is satisfactory, there is a surface makeup method as another means for improving the design. Here, it is difficult to provide a satisfactory design by a conventional coating method in which a single color is repeatedly applied with a means such as a spray or a roll coater to obtain a ceramic tile tone and a natural stone tone tone. Therefore, in order to enhance the design of the siding panel of the present invention, it is preferable to perform random multicolor coating on the surface of the surface material 1 of the siding panel. As the random multicolor coating method, for example, an RS coating (Random select coating) method of Dainippon Paint Co., Ltd. can be employed. By performing deep embossing and random multicolor coating in this way, it is possible to finish the siding panel of the present invention to an appearance close to a ceramic tile or a natural stone tone.
