Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wall panel equipped with a highly fire-resistant hardened gypsum material, and more specifically to a wall panel suitable as an exterior material or an interior material for plumbing areas. It is.

[Prior Art] Gypsum boards have excellent fire resistance and workability, and are highly productive, so they are used in large quantities as building materials. In addition, various kinds of noncombustible boards or quasi-noncombustible boards are known, which are made by combining noncombustible base paper, asbestos paper, rock wool, etc. and gypsum board (for example, fire prevention materials certified by the Ministry of Construction No. 1004, 1012, and 2008). , 2016 No. 2
014, 2017, etc.).

[Problems to be Solved by the Invention] However, since gypsum is water-soluble, it cannot be used for exterior purposes or for parts that use water.

Furthermore, even when used in areas where water is not used, it is necessary to apply surface decoration, which takes time and effort.

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

Further, a wall panel according to a second aspect of the present invention includes a ceramic panel having protrusions on the back surface, and plaster poured and hardened onto the back surface of the panel.

[Function] 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 it can be used as an exterior material or an interior material for plumbing areas. In addition, in the present invention, since the surface side is made of hard ceramic, it has high hardness and is resistant to scratches, does not require surface decoration, and has extremely high strength. Furthermore, in general, ceramics alone do not have crystallization water, so the temperature rises quickly in the event of a fire, but in the wall panel of the present invention, the gypsum contains crystallization water, and the temperature rise in the event of a fire is extremely slow.

[Examples] The present invention will be described in more detail below with reference to examples shown in the drawings.

Each of FIGS. 1 to 4 is a cross-sectional perspective view showing an embodiment of the present invention.

The wall panel shown in FIG. 1 includes a ceramic panel 1 in which a cavity extending parallel to the panel surface is formed, and a hardened gypsum body 3 poured into the cavity 2 of this panel 1 and hardened. It is composed of In this embodiment, the cavity 2 has a rectangular cross-sectional shape.

The wall panel according to the embodiment shown in FIG. 2 includes a ceramic panel 4 having a protrusion 5 formed of a protrusion extending in the longitudinal direction of the panel on the back surface, and hardened gypsum poured onto the back surface of the panel 4. It has a body 6. In this embodiment, the protrusion 5 has a dovetail shape that widens toward its tip, and the adhesion strength between the hardened gypsum 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 a direction parallel to the plate surface has a triangular cross-sectional shape. The rest of the structure is the same as the embodiment shown in FIG.

In the embodiment shown in FIG. 4, the protrusions 5 have equal widths toward the distal end. The rest of the structure is the same as the embodiment shown in FIG.

In the wall panels shown in FIGS. 2 and 4, the protrusions 5 may be formed as elongated protrusions, or may be erected in the form of columns on the back surface of the ceramic panel.

In the wall panels configured in this way, the front side is the ceramic panel 1 or 4, so
There is no risk that gypsum will be dissolved by water such as rain, and it can be used as an exterior material or interior material for plumbing areas. Moreover, since the surface is made of ceramic panel 1 or 4, it has high hardness and is hard to be scratched. Furthermore, there is no need for surface decoration, and the strength is extremely high. Furthermore, there is a gypsum hardened body on the back side or inside 3.
6, the crystallization water of the hardened gypsum body 3.6 makes the temperature rise extremely slow in the event of a fire.

In the embodiments shown in FIGS. 1 and 3, both sides of the wall panel are made of ceramics, so it is also possible to construct a partition wall using only this wall panel.

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

In the wall panels shown in FIGS. 1-4, the ceramic panel 1.4 is preferably formed by extrusion, but may be formed by other methods. For example, in the wall panel shown in FIG. 4, since die cutting can be performed, the ceramic panel 4 can also be formed by die pressing or the like.

The wall panel of the present invention is manufactured by pouring hemihydrate gypsum slurry into the cavity of the ceramic panel or the back surface of the ceramic panel and curing it. In this case, the ceramic panel shown in FIGS. In the panel, it is preferable to close the opening at one end of the cavity and pour the hemihydrous gypsum slurry into it. In addition, in the wall panels shown in FIGS. 2 and 4, it is preferable to set the ceramic panel 4 in a mold with its back side facing up, and then pour hemihydrate gypsum slurry onto it and harden it. After hardening, this gypsum slurry ultimately becomes dihydrate gypsum.

As the ceramic material used in the present invention, various materials such as porcelain, ceramic, porcelain, earthenware, etc. can be employed. Moreover, the surface may be glazed.

A ceramic material mainly composed of Honbushi clay and containing anti-firestone, wallasnite, talc, and feldspar was extrusion molded and fired as shown in Figure 1.3. Next, one end of the cavity of this ceramic panel was closed and a slurry of semi-hydrated gypsum was poured in.
By curing, the wall panel shown in Figure 1.3 was produced.

In addition, in the same way, ceramic materials mainly composed of Honbushi clay and containing anti-firestone, wallasnite, talc, and feldspar were prepared in 2.4.
It was extruded and fired as shown in the figure. This ceramic panel was placed at the bottom of the formwork with the back side facing up, and hemihydrate gypsum slurry was poured in and cured.
The wall panels shown in the figure were manufactured.

[Effects of the Invention] As described above, since the surface side of the wall panel of the present invention is made of ceramic, it has excellent water resistance and can be used as an exterior material or an interior material for water areas. Additionally, since the surface is made of ceramic, it has a high surface hardness and is resistant to scratches, does not require surface decoration, and has extremely high strength. Furthermore, the temperature rise in the event of a fire is extremely slow due to the crystallization water of gypsum, resulting in extremely excellent fire resistance.
