Description

TECHNICAL FIELD The present invention relates to a wall panel provided with a hardened gypsum having high fire resistance, and more particularly to a wall panel suitable as an exterior material or an interior material around water. Is.

[Prior Art] Gypsum boards are widely used as building materials because they are excellent in fire resistance and workability and have high productivity. In addition, various types of non-combustible boards or quasi-non-combustible boards in which non-combustible base paper, asbestos paper, rock wool and the like are combined with gypsum board are known (for example, Ministry of Construction approved fire prevention materials 1004, 1012, 2008). , 2016, 2
014, 2017, etc.).

[Problems to be Solved by the Invention] However, since gypsum is water-soluble, it cannot be used for exterior parts or parts where water is used. In addition, it is necessary to apply surface makeup even when using it on parts that do not use water,
It took time and effort for construction.

[Means for Solving Problems] A wall panel according to a first aspect of the present invention is a ceramic panel in which a cavity extending in a direction parallel to a plate surface is formed, and the wall panel is poured into the cavity. Has a hardened gypsum.

The wall panel according to the second aspect of the present invention has a ceramics panel having protrusions on the back surface and a gypsum cast and cured on the back surface of the panel.

[Operation] In the wall panel of the present invention, since the gypsum itself is not exposed on the surface side of the panel, there is no fear that the gypsum will be dissolved by water such as rain, and the gypsum can be used as an exterior material or an interior material around water. Further, in the present invention, since the surface side is made of hard ceramics, it has a high hardness and is hard to be scratched, and further, the surface makeup is not required and the strength is extremely high. Further, generally, ceramics alone do not have crystal water, so the temperature rises quickly in the case of a fire, but in the wall panel of the present invention, the gypsum has crystal water, and the temperature rise in a fire is extremely slow.

Embodiments The present invention will be described in more detail with reference to the embodiments shown in the drawings.

1 to 4 are sectional perspective views showing an embodiment of the present invention.

The wall panel shown in FIG. 1 includes a ceramics panel 1 in which a cavity extending in a direction parallel to the plate surface is formed, and a gypsum hardened body 3 which is poured into the cavity 2 of the panel 1 and hardened. Is configured. In this embodiment, the cavity 2 has a rectangular cross section.

The wall panel according to the embodiment shown in FIG. 2 has a ceramics panel 4 having on its back surface a projection 5 made of a ridge extending in the longitudinal direction of the panel, and a gypsum hardened by being poured and cured on the back surface of this panel 4. And a body 6. In this embodiment, the projection 5 is formed in a dovetail shape that widens in the direction of its tip, and the adhesion strength between the gypsum hardened body 6 and the ceramic panel 4 is extremely high.

In the wall panel according to the embodiment shown in FIG. 3, the cavity 2 extending in the direction parallel to the plate surface has a triangular sectional shape. Other configurations are similar to those of the embodiment shown in FIG.

In the embodiment shown in FIG. 4, the protrusions 5 are of equal width toward the tip. Other configurations are similar to those of the embodiment shown in FIG.

In the wall panel shown in FIGS. 2 and 4, the protrusion 5 may be formed to be long by using this as a ridge, or may be erected in a columnar shape on the back surface of the ceramic panel.

In each of the wall panels configured in this manner, the front surface side is the ceramics panel 1 or 4,
There is no risk of gypsum being dissolved by water such as rain, and it can be used as an exterior material or interior material around water. Further, since the surface is the ceramic panel 1 or 4, the hardness is high and scratches are unlikely to occur. In addition, no surface makeup is required and the strength is extremely high. Furthermore, the gypsum hardened body 3 on the back or inside,
Since 6 is distributed, the temperature rise at the time of fire becomes extremely slow due to the crystal water of the gypsum hardened bodies 3 and 6.

In addition, in the embodiment shown in FIGS. 1 and 3, both surfaces of the wall panel are made of ceramics, so that the partition wall can be constituted by only the wall panel.

In the embodiment shown in FIGS. 1 and 3, the cross-sectional shape of the cavity is square or triangular, but other cross-sectional shapes may be used, or a honeycomb-shaped cavity may be used.

In the wall panels shown in FIGS. 1 to 4, the ceramic panels 1 and 4 are preferably formed by extrusion molding, but may be formed by other methods. For example, in the wall panel shown in FIG. 4, die-cutting can be performed, so that the ceramic panel 4 can be formed by a die press or the like.

The wall panel of the present invention is manufactured by pouring a hemihydrate gypsum slurry into the cavity of the ceramic panel or the back surface of the ceramic panel and curing the slurry. In this case, the ceramics shown in FIGS. 1 and 3 are used. In the panel, it is preferable to close the opening on one end side of the cavity and pour the hemihydrate gypsum slurry. Further, in the wall panel shown in FIG. 2 and FIG. 4, it is preferable that the ceramics panel 4 is set in the mold with the back surface facing upward, and hemihydrate gypsum slurry is poured onto the ceramics panel 4 to cure it. This gypsum slurry eventually becomes dihydrate gypsum after hardening.

As the material of the ceramics used in the present invention, various materials such as porcelain, earthenware, earthenware and earthenware can be adopted. The surface may be glazed.

A ceramic material mainly composed of kibushi clay, including anti-fire stone, wollastonite, talc, and feldspar was extruded and fired as shown in FIGS. Next, one end of the cavity of this ceramic panel was closed, and a slurry of hemihydrate gypsum was poured into the ceramic panel to cure it, whereby the wall panel shown in FIGS. 1 and 3 was manufactured.

Similarly, the second is ceramic materials containing Kisetsu clay as the main constituent, including anti-firestone, wollastonite, talc, and feldspar.
It was extruded and fired as shown in FIG. This ceramics panel is placed on the bottom of the mold with the back side facing up, and a hemihydrate gypsum slurry is poured into it to cure it.
The wall panel shown in Figure 4 was manufactured.

[Effects of the Invention] As described above, the wall panel of the present invention has extremely excellent water resistance because the surface side is made of ceramics, and can be used as an exterior material or an interior material around water. In addition, since the surface of ceramics is high, the surface hardness is high and scratches are less likely to occur, and the surface makeup is not required, and the strength is extremely high. Furthermore, the temperature rise at the time of a fire is extremely slow due to the water of crystallization of gypsum, so that the fire resistance becomes extremely excellent.
