Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a lightweight aerated concrete (ALC) panel with a tile, and can be used for manufacturing an outer wall panel of a building, for example.

[0002]

BACKGROUND ART To manufacture a lightweight cellular concrete panel used as an outer wall panel of a building, a raw material slurry is placed in a mold, and the slurry is temporarily cured to form a panel master plate, and the panel master plate is removed. It is performed by molding and subjecting the panel original plate to autoclave curing under high temperature and high pressure. In the above, in order to improve the cosmetic properties and design of the outer wall panel, the outer wall panel is provided with tiles. In order to manufacture this outer wall panel with tiles, the raw material slurry is cast into the mold to make a panel original plate, and then the tile surface is exposed and embedded in the panel original plate, and the demolded panel original plate is prepared. Autoclave curing is performed.

[0003]

According to such a method of manufacturing an outer wall panel with tiles, when the original plate with tiles is autoclaved under high temperature and high pressure, the tiles are stable and do not expand or contract even at high temperatures. While the panel original plate itself shrinks, the panel original plate 20 is cracked around the tile 21 as shown in FIG.
2 might occur.

An object of the present invention is to provide a method for producing a lightweight cellular concrete panel with tiles which enables production of a lightweight cellular concrete panel with tiles without the risk of cracking.

[0005]

According to the present invention, a raw material slurry for a lightweight cellular concrete panel is cast in a formwork, and a tile having a high-temperature evaporative substance on the side surface is exposed to a tile of a panel original plate made of this slurry. Let me embed,
The demolded tiled panel original plate is autoclaved to produce a lightweight cellular concrete panel with tiles.

In the above, the high temperature evaporative substance provided on the side surface of the tile is, for example, silicon oil, mineral oil, wax or the like. Further, the thickness of the high temperature evaporation material is determined according to the size of the tile and the like.

The lightweight cellular concrete panel produced by the production method of the present invention can be used as an outer wall panel of a building, a decorative panel for a pillar, a decorative wall, and further as an interior decoration tool.

[0008]

[Function] When the original plate with tiles is cured in an autoclave, the high temperature evaporative substances provided on the sides of the tiles evaporate under high temperature. Therefore, even if the original plate contracts, this contraction is caused by the high temperature evaporative substances. It is absorbed in the gaps formed, and as a result, cracks do not occur and the tile and the panel original plate adhere to each other.

[0009]

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the formwork 1 shown in FIG. 1, a raw material slurry for a lightweight cellular concrete panel is cast. In this frame 1, a reinforcing material of lightweight cellular concrete panel is arranged in advance. The raw material slurry is mainly composed of cement and silica sand, and contains air bubbles. The raw material slurry cast in the mold 1 is aged for a predetermined period of time, whereby it is temporarily hardened to form the panel original plate 2.

The tile 3 is embedded in the original panel 2 with the tile surface 3A exposed. Although only one tile 3 is shown in the drawing, the number of tiles 3 is usually a plurality, and these tiles 3 are embedded side by side in the front, back, left and right. On the side surface 3B of the tile 3, an oil film 4 which is a high-temperature evaporation substance is provided before the tile 3 is embedded in the panel original plate 2, and an anchor member 5 is fixed to the lower surface 3C. The oil film 4 provided on the side surface 3B of the tile 3 is made of, for example, silicon oil, mineral oil, or the like, and may be wax. The anchor member 5 is a thin metal material such as stainless steel, and is fixed to the lower surface 3C by adhesion or the like.

The panel original plate 2 with the tiles 3 embedded therein is then removed from the formwork 1.
The demolded panel original plate 2 is for autoclave curing,
It is carried into a pressure cooker to which high temperature steam is supplied, and the panel original plate 2 is aged in the pressure cooker under high temperature and high pressure.

During the curing of the autoclave, the tile 3 is in a stable state even at a high temperature and therefore does not expand or contract, but the panel original plate 2 itself contracts during the curing. However, since the oil film 4 is provided on the side surface 3B of the tile 3, the oil film 4 evaporates at a high temperature, and a gap corresponding to the thickness of the oil film 4 is provided around the tile 3, so that the panel original plate 2 is Even if it contracts toward 3, the contracted part is absorbed in the gap due to the oil film 4, so that the original panel 2
It does not crack. FIG. 2 shows the state at this time. In addition, the panel original plate 2 contracts to adhere to the tile 3, and good adhesiveness between the panel original plate 2 and the tile 3 is secured.

Further, in this embodiment, the anchor member 5 is provided on the lower surface 3C of the tile 3 pushed into the panel original plate 2.
Since the anchor member 5 is provided, the bonding strength between the panel original plate 2 and the panel 3 is increased.

After the autoclave curing, the panel original plate 2 with tiles is a lightweight cellular concrete panel, and the lightweight cellular concrete panel with tiles taken out from the pressure cooker is sent to the painting process and the tiles 3 are arranged. Areas that are not covered are painted.

The lightweight cellular concrete panel with tiles obtained by the above manufacturing method is good without cracks, and the adhesion and bonding strength of the tile 3 are also good.

In the above, the thickness of the oil film 4 provided on the side surface 3B of the tile 3 is determined by the thickness of the panel original plate 2 around the tile 3.
Is set in correspondence with the shrinkage of the tile 3. Therefore, it is determined according to the size of the tile 3, the composition component of the raw material slurry, the ratio thereof, and the like.

In the above embodiment, the lower surface 3C of the tile 3 is used.
Although the anchor member 5 is provided in the above, the anchor member 5 does not necessarily have to be provided, and if the anchor member 5 is provided,
The effects described above can be obtained.

[0018]

According to the present invention, when the tile surface is exposed and embedded in the panel original plate in the form, a high temperature evaporating substance is provided on the side surface of the tile, so that even if the panel original plate shrinks during autoclave curing. The shrinkage of the panel original plate is absorbed in the gaps caused by the high-temperature evaporating substances, so that the generation of cracks can be prevented, and a lightweight cellular concrete panel with tiles of good quality can be manufactured.
