Description

  The present invention relates to a non-combustible interior panel with a covering sheet in which a resin sheet is attached to a non-combustible core panel and a mounting structure thereof.

  In various buildings such as houses and stores, there is a case where an uneven panel or an interior panel with a design is arranged on the surface of an interior base material forming a wall surface for the purpose of improving the design of the interior. Since the interior panel is disposed on the surface of the interior base material, it is necessary to prevent accidents due to combustion or dropping in a disaster such as a fire or an earthquake. In order to prevent such accidents, it is considered to improve the fire performance by adding non-combustibility to the interior panel by using non-combustible materials such as cement-based materials, ceramic-based materials, and metals as materials for the interior panels. It is done. As a nonflammable interior panel with improved fireproof performance, for example, there is one described in Patent Document 1.

  In addition, as a method of attaching the non-combustible interior panel to the interior base material, there are a method of applying an adhesive to the back surface of the non-combustible interior panel and fixing it, and a method using metal fittings such as finish nails, screws, bolts, and nails. Many are used. When attaching more firmly, two methods may be used together.

JP-A-5-263485

By the way, when an earthquake occurs, the building swings, and the interior base material to which the interior panel is fixed is deformed. At this time, when the interior panel is directly coupled and fixed to the interior base material, the interior panel tries to follow the deformation of the interior base material. When the material of the interior panel is a cement-based material or a ceramic-based material with improved nonflammability, since it is highly brittle, there is a risk that it will be damaged due to cracks, cracks, etc. caused by the load accompanying deformation. If the interior panel is damaged, the interior panel may fall off and cause harm such as hitting a person.
In addition, as a material for the interior panel, instead of the above cement material, it is conceivable to use a metal material having low brittleness and not easily damaged, but in this case, the weight is often increased and the hardness is high, The risk of falling off increases, which is not preferable.

  Further, as described above, there are various methods for attaching the noncombustible interior panel to the interior base material. Both methods are both long and short, but it is also important to determine what is the best mounting method for mounting the interior panel.

  The present invention has been made in view of such problems, and has excellent design characteristics and is also suitable for a non-combustible interior panel with a covering sheet that is not easily damaged or dropped even during a disaster and the non-combustible interior panel. Is to provide a method.

1st invention is a nonflammable interior panel with a covering sheet which coat | covered the core material panel which consists of a nonflammable material with the resin sheet,
The core panel has a design surface arranged on the indoor side, a back surface opposite to the design surface, and a side surface connecting the design surface and the back surface,
The resin sheet is a non-combustible coating sheet characterized in that one resin sheet is stretched and pasted so as to cover at least the entire design surface, the entire side surface, and a part of the back surface of the core panel. It exists in a sex interior panel (Claim 1).

2nd invention is the attachment structure which attaches the incombustible interior panel with a covering sheet of 1st invention to interior base material,
Using a metal joiner having a bottom plate portion, a side wall portion erected from at least one end of the bottom plate portion, and a flange portion bent in a direction opposite to the bottom plate portion from the tip of the side wall portion,
The bottom plate portion of the metal joiner is brought into contact with and fixed to the interior base material, and the side end portions of the non-combustible interior panel with the covering sheet are sandwiched between the flange portion and the interior base material, respectively. The non-combustible interior panel mounting structure is characterized in that it is fixed.

In the first invention, the one resin sheet is stretched and pasted so as to cover the entire design surface, the entire side surface, and a part of the back surface of the core panel. Therefore, even if the core panel is damaged when an earthquake occurs, the resin sheet serves as a reinforcing material and can maintain its shape. In particular, the resin sheet is obtained by stretching one sheet and covering not only the design surface but also part of the side surface and the back surface, thereby obtaining a very excellent shape maintenance effect. Can do.
Moreover, the design of the said noncombustible interior panel with a coating sheet can be freely changed by changing the color, pattern, etc. of the said resin sheet. Therefore, the designability of the non-combustible interior panel with the covering sheet can be improved.

  In the second invention, the bottom plate portion of the metal joiner is brought into contact with and fixed to the interior base material, and the non-combustible interior panel with the covering sheet is provided between the flange portion and the interior base material, respectively. The side end portion of this is sandwiched and fixed. That is, the non-combustible interior panel with a covering sheet and the interior base material are not directly coupled. Therefore, even when deformation such as deflection occurs in the interior base material due to an earthquake or the like, the non-combustible interior panel with a covering sheet is mounted so as to be relatively movable with respect to the interior base material. It is hard to receive. Therefore, the load concerning the said nonflammable interior panel with a coating sheet can be reduced, and a failure | damage can be prevented.

  Moreover, since the above-mentioned joiner is made of metal, it is higher in strength and excellent in heat resistance and nonflammability than resin-made joiners. Therefore, even when a disaster such as an earthquake or a fire occurs, the shape can be maintained and the non-combustible interior panel with a covering sheet can be fixed.

  In the present invention, the shape maintaining effect of the incombustible interior panel with the covering sheet and the synergistic effect of the damage preventing effect in the mounting structure of the incombustible interior panel with the covering sheet exhibit an extremely excellent shape maintaining effect. be able to. Furthermore, by using the above-described excellent mounting structure, the non-combustible interior panel with the covering sheet that maintains the shape can be continuously fixed to the interior base material even in the event of a disaster, and the non-combustible interior panel with the covering sheet Can be reliably prevented from falling off.

  As described above, according to the present invention, it is possible to provide an incombustible interior panel with a covering sheet that has excellent design properties and is less likely to be damaged or dropped even during a disaster, and an optimal mounting method for the incombustible interior panel. it can.

Explanatory drawing which shows the arrangement | positioning state of the nonflammable interior panel with a coating sheet in Example 1. FIG. The elements on larger scale of the AA arrow cross section of FIG. The perspective view which shows the design surface of the noncombustible interior panel with a coating sheet in Example 1. FIG. The perspective view which shows the back surface of the noncombustible interior panel with a coating sheet in Example 1. FIG. FIG. 4 is an enlarged sectional view taken along line BB in FIG. 3.

  As the material for the resin sheet shown in the present invention, various resin materials such as olefin and polyethylene terephthalate can be used, and it is particularly preferable to use vinyl chloride resin. Since the vinyl chloride resin is difficult to burn, the nonflammability of the nonflammable interior panel with a covering sheet is not deteriorated.

  Further, the resin sheet is arranged in a connected state with no cuts provided in a range covering the entire design surface, the entire side surface, and a part of the back surface of the core panel. (Claim 2). In this case, since the resin sheet covering the core panel is not cut, the reinforcing effect of the resin sheet can be improved. Therefore, even when the core panel is damaged, the shape can be more reliably maintained. Moreover, since there is no cut | interruption in the said resin sheet, the designability of the nonflammable interior panel with a coating sheet which affixed this resin sheet can be improved more.

Moreover, it is preferable that the board thickness t (mm) of the said noncombustible interior panel with a coating sheet is 6 mm <= t <= 50mm. In this case, the strength required for the non-combustible interior panel with a covering sheet can be reliably ensured.
When the thickness t (mm) of the non-combustible interior panel with a covering sheet is t <6 mm, the thickness of the non-combustible interior panel with the covering sheet is reduced, so that the rigidity of the non-combustible interior panel with the covering sheet is lowered. When t> 50 mm, the amount of protrusion into the room is large. Therefore, when the non-combustible interior panel with the covering sheet is used as a part of the wall surface made of the interior base material, the step between the non-combustible interior panel with the covering sheet and the interior base material is conspicuous, There is a risk of damage. Moreover, when the said nonflammable interior panel with a coating sheet is used for the whole wall surface which consists of the said interior base material, there exists a possibility that a problem that indoor space may become narrow arises.
In addition, when uneven | corrugated shape is formed in the design surface of the said nonflammable interior panel with a coating sheet, plate | board thickness t (mm) points out the distance between the bottom part of the said uneven | corrugated shape, and the said back surface.

  Moreover, it is preferable that the said design surface of the said core material panel is an uneven | corrugated design surface which exhibited uneven | corrugated shape (Claim 4). In this case, the design freedom in the design surface can be improved. Therefore, the designability of the non-combustible interior panel with a covering sheet can be improved.

Moreover, it is preferable that the surface area of the said uneven | corrugated design surface is more than 1.00S-1.60S with respect to the area S of the plane area | region in the planar view of the said design surface of the said core material panel (Claim 5). In this case, the resin sheet can be reliably attached to the core panel while being stretched.
When the surface area of the uneven design surface is 1.00 S or less, the uneven shape cannot be formed.
Moreover, when the surface area of the said uneven | corrugated design surface exceeds 1.60S, since it exceeds the limit of the elongation amount of the said resin sheet, there exists a possibility that it may become impossible to affix.

  Moreover, it is preferable that the said core material panel consists of a zonotolite type | system | group calcium silicate (Claim 6). Zonotolite-based calcium silicate has extremely small thermal shrinkage and thermal expansion, and is less likely to be damaged when heated to a high temperature and after cooling. Moreover, even when it cools rapidly after heating to high temperature, a shape can be maintained, without collapsing. Therefore, even in the event of a fire, the core panel can be prevented from being damaged during the fire, and the fireproof performance of the non-combustible interior panel with the covering sheet can be reliably maintained.

  On the other hand, cement materials (such as tobermorite calcium silicate) and ceramic materials excluding zonotlite-based calcium silicate used for noncombustible interior panels, when heated to a high temperature by a fire, even if they do not burn, Prone to cracking or cracking. In addition, cement-based materials and ceramic-based materials other than zonotlite-based calcium silicate are easily disintegrated when water is discharged by a sprinkler or the like at the time of initial fire extinguishing and rapidly cooled from a heated state. For this reason, the non-combustible interior panel falls off at the initial stage of fire occurrence, and the fireproof performance is likely to be lost. Although it is conceivable to use a metal material that is not easily damaged by thermal shock, it is preferable to use zonotlite-based calcium silicate because zonotlite-based calcium silicate is more excellent in terms of heat resistance.

Moreover, it is preferable that the thickness of the said resin sheet is 0.2 +/- 0.05mm in the state before sticking (Claim 7). In this case, the non-flammable performance can be improved by extending the resin sheet while being surely attached to the core panel and reducing the basis weight of the resin sheet.
When the thickness of the resin sheet is 0.195 mm or less, there is a possibility of breaking when the resin sheet is applied while being stretched.
Moreover, when the thickness of the said resin sheet exceeds 0.205 mm, the said resin sheet affixed on the said nonflammable interior panel with a coating sheet tends to burn, and there exists a possibility that nonflammable performance may deteriorate. Moreover, when sticking on an uneven | corrugated design surface, since the followable | trackability of the said resin sheet deteriorates, there exists a possibility that it cannot stick to a detail.

  Moreover, it is preferable to form the outer peripheral plane part which consists of a plane parallel to the said back surface along the outline of the outer periphery on the said design surface. In this case, when the mounting method according to the second aspect of the present invention is employed, the outer peripheral flat portion and the inner base material are sandwiched between the flange portion provided in the joiner and the interior base material. Since it is arrange | positioned so that the collar part of a Joiner may follow, there is no lifting of the said collar part, and designability can be improved.

  Next, as the material of the joiner used in the second invention, various metal materials such as aluminum alloy, galvalume steel, stainless steel, galvanized steel plate and the like can be used.

  The joiner has a cross-sectional hat shape having a bottom plate portion, a pair of side wall portions erected from both side ends of the bottom plate portion, and a pair of flange portions bent in directions away from the ends of the pair of side wall portions. The metal hat-type joiner can be used to sandwich and fix the side end portions of the non-combustible interior panel with the covering sheet between the pair of flange portions and the interior base material. ). In this case, the opposing ends of the two non-combustible interior panels with covering sheets that are adjacent in the vertical and horizontal directions can be fixed with one hat-type joiner. Therefore, the mounting workability and work efficiency of the non-combustible interior panel with the covering sheet can be improved.

  The hat-type joiner may be provided with a lid so as to cover a groove formed by the bottom plate portion and the pair of side end portions. Further, the lid member may be colored or designed. In this case, the design of the hat-type joiner can be improved and the degree of freedom in design can be improved.

Example 1
An incombustible interior panel 1 with a covering sheet according to Example 1 of the present invention will be described with reference to FIGS.
As shown in FIG. 5, the incombustible interior panel 1 with a covering sheet of this example has a core panel 10 made of an incombustible material covered with a resin sheet 20. The core material panel 10 has a design surface 11 disposed on the indoor side, a back surface 12 opposite to the design surface 11, and a side surface 13 connecting the design surface 11 and the back surface 12. One resin sheet 20 is stretched and pasted so as to cover at least the entire design surface 11, the entire side surface 13 and the back surface 12 of the core panel 10. In FIG. 5, the thickness of the resin sheet 20 is emphasized for easy understanding of the configuration, and is greatly different from the actual dimensional ratio.

The details will be described below.
As shown in FIGS. 3 to 5, the incombustible interior panel 1 with a covering sheet is formed by covering a core panel 10 with a resin sheet 20. As shown in FIG. 5, the core material panel 10 has a design surface 11 and a back surface 12 composed of a flat surface arranged on the opposite side of the design surface 11. Moreover, the design surface 11 and the back surface 12 are connected by the side surface 13 which consists of a plane. The design surface 11 is a concavo-convex design surface 111 having a quadrangular pyramid-shaped concavo-convex shape, and an outer peripheral flat surface portion 112 formed of a plane parallel to the back surface 12 is formed along the outer peripheral contour thereof.

  The core material panel 10 is made of zonotlite-based calcium silicate, and is formed by forming a concavo-convex design surface 111 and an outer peripheral flat surface portion 112 by cutting a flat base plate having a square shape of 500 mm × 500 mm. In this example, as shown in FIG. 5, the distance between the bottom of the concavo-convex shape of the concavo-convex design surface 111 and the back surface 12 was defined as a plate thickness t (mm), and t = 10 mm. In addition, the outer peripheral flat surface portion 112 is defined as a 10 mm inward range from the outer contour of the irregular design surface 111. In addition, the quadrangular pyramid shape forming the concavo-convex shape is a square having a bottom surface of 60 mm × 60 mm, and the height H of the concavo-convex shape is 9 mm. The concavo-convex shape is formed so that the square side forming the bottom surface of the quadrangular pyramid and the side forming the outer periphery of the core panel 10 are parallel to each other. Moreover, in this example, the surface area of the concavo-convex design surface 111 is 1.044 S with respect to the area S of the planar region in the plan view of the concavo-convex design surface 111 of the core panel 10.

  The resin sheet 20 is made of a vinyl chloride resin that has been certified as non-combustible, and has a square shape of 550 mm × 550 mm before being attached. Moreover, in the state before sticking, the thickness of the resin sheet 20 is 0.2 mm. The above non-combustibility certification is determined by the Building Standard Law (Article 2-9). In this example, the material that has been certified as non-combustible refers to a material that is certified according to the exothermic test evaluation method, which is a performance evaluation based on the above regulations. In this case, since the resin sheet 20 is hard to burn, the nonflammability of the nonflammable interior panel with a covering sheet is not deteriorated.

  In this example, the resin sheet 20 was stuck to the core panel 10 using a vacuum molding machine (not shown). The core material panel 10 is arranged on a table arranged in a chamber box of the vacuum forming machine. At this time, the core material panel 10 is arranged in a state where the outer peripheral end portion is floated. In the chamber box, the resin sheet 20 is arranged above the core panel 10, and the space in the chamber box is divided into two parts by the resin sheet 20 so that the upper and lower spaces are sealed. After the resin sheet 20 is heated by a heater to be easily stretched, the lower space where the core material panel 10 is arranged is evacuated so that the resin sheet 20 is adhered to and adhered to the core material panel 10. At this time, even in the corners and the uneven shape of the core panel 10, the resin sheet 20 is applied while being stretched along the shape, so that wrinkles and the like do not occur. Moreover, the resin sheet 20 can be affixed to the back surface 12 of the core material panel 10 by arrange | positioning in the state which floated the edge part of the core material panel 10, as shown in FIG.4 and FIG.5. In the incombustible interior panel with a cover sheet of this example, the resin sheet 20 covered a range of about 10 mm inward from the entire design surface 11, the entire side surface 13, and the outer periphery of the back surface 12.

  In this example, as shown in FIG.1 and FIG.2, the joiner 3 used for fixing the nonflammable interior panel 1 with a covering sheet consists of a lightweight aluminum alloy, and the adjacent nonflammable interior panel 1 with a covering sheet The first joiner 31 disposed between the two and the second joiner 32 that fixes the end of the non-combustible interior panel 1 with the covering sheet disposed on the outside are used. As shown in FIG. 2, the first joiner 31 includes a first bottom plate portion 311, a pair of first side wall portions 313 erected from both side ends of the first bottom plate portion 311, and the pair of first side wall portions 313. A hat-shaped joiner having a hat-shaped cross section having a pair of first flange portions 311 bent in a direction away from the tip. Further, as shown in FIG. 2, the second joiner 32 includes a second bottom plate portion 321, a second side wall portion 323 erected from one end of the second bottom plate portion 321, and a tip of the second side wall portion 323. It has the 2nd collar part 322 bent in the direction opposite to 2 bottom-plate part 321. FIG. In addition, the resin sheet 20 is abbreviate | omitted in the cross section of the nonflammable interior panel 1 with a coating sheet shown in FIG.

Next, the attachment method of the nonflammable interior panel 1 with a covering sheet in this example will be described.
In this example, as shown in FIG. 1, attachment is performed from the non-combustible interior panel 1 with a covering sheet located in the lower stage, and the upper stage is sequentially attached. First, the second joiner 32 positioned below the non-combustible interior panel 1 with the covering sheet disposed in the lower stage is disposed such that the second flange 322 is positioned upward and is horizontal. A first joiner 31 disposed between adjacent non-combustible interior panels 1 with a covering sheet is disposed vertically in the lower stage. The incombustible interior panel 1 with the covering sheet is sandwiched between the second end portion 322 of the second joiner 32 and the interior base material 8, and the side end portion 14 positioned below is sandwiched between the first end portion 312 of the first joiner 31. And the interior base material 8 sandwich the side end portion 14 facing the non-combustible interior panel 1 with the covering sheet adjacent thereto.

  Next, the first joiner 31 located above the non-combustible interior panel 1 with the covering sheet disposed in the lower stage shown in FIG. 1 is disposed, and the first joiner 31 of the first joiner 31 and the interior base material 8 The side end portion 14 located above the incombustible interior panel 1 with the covering sheet disposed in the lower stage is sandwiched. Also in the upper stage, similarly to the lower stage, the first joiner 31 disposed between adjacent non-combustible interior panels 1 with a covering sheet is disposed vertically. The incombustible interior panel 1 with a covering sheet disposed in the upper stage is sandwiched between the second end portion 322 of the second joiner 32 and the interior base material 8, and the side end portion 14 positioned below is sandwiched between the first joiner 31. The first end portion 312 and the interior base material 8 sandwich the side end portion 14 facing the adjacent non-combustible interior panel 1 with a covering sheet. Next, the first joiner 31 located above the incombustible interior panel 1 with the covering sheet disposed in the upper stage is disposed, and the first joiner 31 is disposed in the upper stage by the first flange portion 312 and the interior base material 8. The side end portion 14 located above the non-combustible interior panel 1 with the covering sheet is sandwiched.

In this example, the above assembling procedure is adopted, but the present invention is not limited to this. Moreover, although the 2nd joiner 32 is not provided in the left-right both ends of the nonflammable interior panel 1 with a covering sheet, the 2nd joiner 32 may be provided in the right-and-left both ends, and a parting material may be provided. Further, in the second joiner 32, since the second bottom plate portion 321 is exposed, the design property can be improved by providing a parting material so as to cover the second bottom plate portion 321.
Further, in the cross-sectional shape of the joiner 3, those having various shapes such as a substantially H shape and a substantially U shape can be used.

The effect in this example is demonstrated.
In this example, as shown in FIGS. 3 to 5, the resin sheet 20 is stretched so as to cover the entire design surface 11, the entire side surface 13, and a part of the back surface 12 of the core panel 10. It is pasted on. Therefore, even if the core panel 10 is damaged when an earthquake occurs, the resin sheet 20 serves as a reinforcing material and can maintain its shape. In particular, the resin sheet 20 stretches a single sheet and continuously covers not only the design surface 11 but also part of the side surface 13 and the back surface 12, thereby obtaining a very excellent shape maintaining effect. Can do.
Moreover, the design of the incombustible interior panel 1 with a covering sheet can be freely changed by changing the color, pattern, or the like of the resin sheet 20. Therefore, the designability of the incombustible interior panel 1 with the covering sheet can be improved.

  Further, as shown in FIGS. 1 and 2, the first bottom plate portion 311 of the first joiner 31 and the second bottom plate portion 321 of the second joiner 32 are brought into contact with and fixed to the interior base material 8, and the first flange portion is fixed. The side end portions of the incombustible interior panel 1 with a covering sheet are sandwiched and fixed between the 312 and the second flange portion 322 and the interior base material 8. That is, the incombustible interior panel 1 with the covering sheet and the interior base material 8 are not directly coupled. Therefore, even when deformation such as deflection occurs in the interior base material 8 due to an earthquake or the like, the non-combustible interior panel 1 with the covering sheet is mounted so as to be relatively movable with respect to the interior base material 8, and therefore, the influence of the deformation. It is hard to receive. Therefore, the load concerning the nonflammable interior panel 1 with a covering sheet can be reduced, and the breakage can be prevented.

  In addition, since the first joiner 31 and the second joiner 32 of this example are made of an aluminum alloy, they have higher strength, higher incombustibility, and higher heat resistance than resin joiners and the like. Therefore, even in the event of a disaster such as a fire or an earthquake, the shape can be maintained and the incombustible interior panel 1 with the covering sheet can be fixed.

  Moreover, the shape maintenance effect which the nonflammable interior panel 1 with a covering sheet has, and the synergistic effect of the damage prevention effect in the attachment structure of the nonflammable interior panel 1 with a covering sheet can exhibit an extremely excellent shape maintaining effect. . Furthermore, by using the above-described excellent mounting structure, the non-combustible interior panel 1 with the covering sheet that maintains the shape can be continuously fixed to the interior base material 8 even in the event of a disaster. 1 can be reliably prevented from falling off.

  Moreover, as shown in FIGS. 3-5, the notch is not provided in the range which the resin sheet 20 covers the whole design surface 11 of the core material panel 10, the whole side surface 13, and a part of back surface 12. As shown in FIG. , Arranged in a connected state. In this case, since the resin sheet 20 covering the core panel 10 is not cut, the reinforcing effect of the resin sheet 20 can be improved. Therefore, even when the core panel 10 is damaged, the shape can be more reliably maintained. Moreover, since there is no cut in the resin sheet 20, the designability of the incombustible interior panel 1 with the covering sheet to which the resin sheet 20 is attached can be further improved.

Moreover, as shown in FIG. 5, the plate | board thickness t (mm) of the nonflammable interior panel 1 with a coating sheet is 10 mm, and exists in the range of 6 mm <= t <= 50mm. Therefore, the strength required for the incombustible interior panel 1 with the covering sheet can be reliably ensured.
Moreover, as shown in FIG.3 and FIG.5, the design surface 11 of the core material panel 10 is the uneven | corrugated design surface 111 which exhibited uneven | corrugated shape. Therefore, the degree of freedom of design on the design surface 11 can be improved. Therefore, the designability of the incombustible interior panel 1 with a covering sheet can be improved.

  Moreover, the surface area of the uneven | corrugated design surface 111 is 1.044S with respect to the area S of the plane area | region in planar view of the design surface 11 of the core material panel 10, and exists in the range of more than 1.00S-1.60S. Therefore, the resin sheet 20 can be reliably attached to the core material panel 10 while being stretched.

  The core panel 10 is made of zonotolite calcium silicate. Zonotolite-based calcium silicate has extremely small thermal shrinkage and thermal expansion, and is less likely to be damaged when heated to a high temperature and after cooling. Moreover, even when it cools rapidly after heating to high temperature, a shape can be maintained, without collapsing. Therefore, even in the event of a fire, damage to the core panel 10 can be prevented, and the fireproof performance of the incombustible interior panel 1 with the covering sheet can be reliably maintained.

  Moreover, the thickness of the resin sheet 20 in this example is 0.2 mm in the state before sticking, and exists in the range of 0.2 ± 0.05 mm. For this reason, the resin sheet 20 can be reliably attached to the core panel 10 while being stretched, and the non-flammable performance can be improved by reducing the basis weight of the resin sheet 20.

  As shown in FIGS. 3 and 5, the design surface 11 is formed with an outer peripheral plane portion 112 made of a plane parallel to the back surface 12 along the outer contour. Therefore, the outer peripheral flat surface portion 112 is sandwiched between the first flange portion 312 provided in the first joiner 31 and the second flange portion 322 provided in the second joiner 32 and the interior base material 8, thereby Since the 1st collar part 312 and the 2nd collar part 322 are arrange | positioned so that the 1st collar part 312 and the 2nd collar part 322 may not be lifted, the design property can be improved.

  Further, the first joiner 31 is separated from the first bottom plate portion 311, the pair of first side wall portions 313 erected from both side ends of the first bottom plate portion 311, and the tips of the pair of first side wall portions 313. A hat-type joiner having a hat-shaped cross section having a pair of first flange portions 312 bent in the direction. The first joiner 31 is fixed by sandwiching a side end portion of the incombustible interior panel 1 with a covering sheet between the pair of first flange portions 312 and the interior base material 8. Therefore, the opposing edge part of the said nonflammable interior panel 1 with the said coating sheet adjacent vertically and horizontally can be fixed with the one 1st joiner 31. FIG. Therefore, the mounting workability and work efficiency of the nonflammable interior panel 1 with the covering sheet can be improved.

  Thus, according to this example, it is possible to provide an incombustible interior panel with a covering sheet that is excellent in design and is less likely to be damaged or dropped even during a disaster, and an optimal mounting method for the incombustible interior panel. it can.

The resin sheet is stretched out so as to cover at least the entire design surface, the entire side surface, and a part of the back surface of the core panel, and the design of the core panel. In the incombustible interior panel with a covering sheet , the entire surface, the entire surface of the side surface, and a part of the back surface are not provided with a cut and are arranged in a connected state ( Claim 1).

2nd invention is the attachment structure which attaches the incombustible interior panel with a covering sheet of 1st invention to interior base material,
Using a metal joiner having a bottom plate portion, a side wall portion erected from at least one end of the bottom plate portion, and a flange portion bent in a direction opposite to the bottom plate portion from the tip of the side wall portion,
The bottom plate portion of the metal joiner is brought into contact with and fixed to the interior base material, and the side end portions of the non-combustible interior panel with the covering sheet are sandwiched between the flange portion and the interior base material, respectively. It is in the mounting structure of the nonflammable interior panel characterized by being fixed by (Claim 7 ).
.

Moreover, the notch is not provided in the range which covers the whole surface of the said design surface of the said core material panel, the whole surface of the said side surface, and a part of said back surface, and the said resin sheet is distribute | arranged . In this case, since the resin sheet covering the core panel is not cut, the reinforcing effect of the resin sheet can be improved. Therefore, even when the core panel is damaged, the shape can be more reliably maintained. Moreover, since there is no cut | interruption in the said resin sheet, the designability of the nonflammable interior panel with a coating sheet which affixed this resin sheet can be improved more.

Further, the cover sheet with incombustible interior panel having a thickness t (mm) is preferably 6mm ≦ t ≦ 50mm (claim 2). In this case, the strength required for the non-combustible interior panel with a covering sheet can be reliably ensured.
When the thickness t (mm) of the non-combustible interior panel with a covering sheet is t <6 mm, the thickness of the non-combustible interior panel with the covering sheet is reduced, so that the rigidity of the non-combustible interior panel with the covering sheet is lowered. When t> 50 mm, the amount of protrusion into the room is large. Therefore, when the non-combustible interior panel with the covering sheet is used as a part of the wall surface made of the interior base material, the step between the non-combustible interior panel with the covering sheet and the interior base material is conspicuous, There is a risk of damage. Moreover, when the said nonflammable interior panel with a coating sheet is used for the whole wall surface which consists of the said interior base material, there exists a possibility that a problem that indoor space may become narrow arises.
In addition, when uneven | corrugated shape is formed in the design surface of the said nonflammable interior panel with a coating sheet, plate | board thickness t (mm) points out the distance between the bottom part of the said uneven | corrugated shape, and the said back surface.

Moreover, it is preferable that the said design surface of the said core material panel is an uneven | corrugated design surface which exhibited uneven | corrugated shape (Claim 3 ). In this case, the design freedom in the design surface can be improved. Therefore, the designability of the non-combustible interior panel with a covering sheet can be improved.

Moreover, it is preferable that the surface area of the said uneven | corrugated design surface is more than 1.00S-1.60S with respect to the area S of the plane area | region in the planar view of the said design surface of the said core material panel (Claim 4 ). In this case, the resin sheet can be reliably attached to the core panel while being stretched.
When the surface area of the uneven design surface is 1.00 S or less, the uneven shape cannot be formed.
Moreover, when the surface area of the said uneven | corrugated design surface exceeds 1.60S, since it exceeds the limit of the elongation amount of the said resin sheet, there exists a possibility that it may become impossible to affix.

The core panel is made of zonotlite-based calcium silicate . Zonotolite-based calcium silicate has extremely small thermal shrinkage and thermal expansion, and is less likely to be damaged when heated to a high temperature and after cooling. Moreover, even when it cools rapidly after heating to high temperature, a shape can be maintained, without collapsing. Therefore, even in the event of a fire, the core panel can be prevented from being damaged during the fire, and the fireproof performance of the non-combustible interior panel with the covering sheet can be reliably maintained.

Moreover, it is preferable that the thickness of the said resin sheet is 0.2 +/- 0.05mm in the state before sticking (Claim 5 ). In this case, the non-flammable performance can be improved by extending the resin sheet while being surely attached to the core panel and reducing the basis weight of the resin sheet.
When the thickness of the resin sheet is 0.195 mm or less, there is a possibility of breaking when the resin sheet is applied while being stretched.
Moreover, when the thickness of the said resin sheet exceeds 0.205 mm, the said resin sheet affixed on the said nonflammable interior panel with a coating sheet tends to burn, and there exists a possibility that nonflammable performance may deteriorate. Moreover, when sticking on an uneven | corrugated design surface, since the followable | trackability of the said resin sheet deteriorates, there exists a possibility that it cannot stick to a detail.

The aforementioned design surface, it is preferable that is formed with an outer peripheral flat portion made of the back surface and a plane parallel along the contour of the outer periphery (claim 6). In this case, when the mounting method according to the second aspect of the present invention is employed, the outer peripheral flat portion and the inner base material are sandwiched between the flange portion provided in the joiner and the interior base material. Since it is arrange | positioned so that the collar part of a Joiner may follow, there is no lifting of the said collar part, and designability can be improved.

The joiner has a cross-sectional hat shape having a bottom plate portion, a pair of side wall portions erected from both side ends of the bottom plate portion, and a pair of flange portions bent in directions away from the ends of the pair of side wall portions. the use of a metal hat-joiner, can be fixed by each sandwiching a side end portion of the cover sheet with incombustible interior panel between the pair of flange portions and the interior base material (claim 8 ). In this case, the opposing ends of the two non-combustible interior panels with covering sheets that are adjacent in the vertical and horizontal directions can be fixed with one hat-type joiner. Therefore, the mounting workability and work efficiency of the non-combustible interior panel with the covering sheet can be improved.
