Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for curing concrete plates with decorative plates made of tiles or the like using high-temperature and high-pressure steam.

Conventional technology The conventional high-temperature, high-pressure curing method for PC boards involves curing a plurality of PC boards stacked on top of one another using a square pipe or the like on a curing cart. However, during curing, alkaline components such as calcium hydroxide that ooze out from the PC board due to heating dissolves in the condensed water that adheres to the concrete board and becomes alkaline water, which drips onto the decorative surface and alkali from the joints and around the PC board. Water got around the decorative surface, causing alkaline corrosion on the decorative surface.

Problems to be Solved by the Invention When the decorative surface faces downward, alkaline water flows around the decorative surface from the joints and around the PC board and solidifies, causing alkali corrosion. If the decorative surface is facing upward, alkaline water may drip onto the decorative surface from the upper PC board.
Alkaline water overflowed from the joints, causing alkaline corrosion to the decorative surfaces. Additionally, since the stacking jig was in contact with the decorative surface during stacking, alkaline water accumulated in the area where the stacking jig was in contact, causing alkaline corrosion.

Means for Solving the Problems The present invention takes these points into consideration and provides a high-temperature, high-pressure steam curing method for a concrete plate to which a decorative board has been attached in order to solve the above-mentioned drawbacks.
That is, in the present invention, when curing a concrete plate to which a decorative plate is attached at high temperature and high pressure, the decorative side is turned upward,
The alkaline water that flows down from the upper PC board is prevented by a flat or corrugated metal iron plate, special resin, rubber board, etc. protection plate, and the protection board is installed from the decorative surface to prevent the alkaline water coming out from the PC board from adhering to the decorative surface. In order to improve the flow of alkaline water gushing out from the floating joints, the PC board is sloped at least 1 degree (usually 5 degrees to 25 degrees).
The loading jig is designed so that it does not come into contact with decorative surfaces to prevent alkaline water from accumulating around the loading jig.

Function: Thus, in the high-temperature, high-pressure steam curing method for a concrete board to which a decorative board according to the present invention is attached, the alkaline water generated during curing does not adhere to the decorative surface of the PC board, and the decorative surface is free from alkali corrosion. PC boards can be obtained extremely easily and the quality of PC boards can be improved.

Embodiment FIG. 1 is a front sectional view of a first case in which a steam heating curing method is applied to a PC board according to the present invention, and FIG. 2 is a sectional view of the same PC board.

In the figure, 1 is a PC board, which is made of concrete board.
A decorative board 2 made of tiles, etc. is pasted to the decorative board 2.
The PC is placed on each square pipe 5 with the side facing upward.
A large number of concrete blocks 6 are stacked as spacers near both ends of the square pipe 5 where the plate 1 is not placed. In addition, each square pipe 5 is connected to the bottom square pipe 5 by interposing a distance block 4 between it and the trolley 3 below one side thereof.
are stacked with a slope a. Also, 7 is a protective iron plate that is placed on every other square pipe 5 on which no PC board 1 is placed so as not to directly touch the decorative board 2 of the PC board 1, and is spaced by a concrete block 6. This prevents the alkaline water 8 from dripping from the PC board 1. Also, the concrete block 6 connects the square pipe 5 near both ends of the square pipe 5 further above.
is placed so that the decorative surface 2 of the PC board 1 does not come into contact with anything.

FIG. 3 shows a front view of the second case in which the high-temperature and high-pressure steam curing method is applied to the PC board according to the present invention. FIG. 4 shows a slope view of the pallet 9 stacked in the same tier.

In the figure, 1 is a PC board made of a concrete board, and a decorative board 2 made of tiles, etc. is attached to it.
They are placed on each stacked pallet 9 with the side facing upward. The stacked pallets 9 support the upper stacked pallets 9 with square supports 10.
The PC board supporting material 11 has a slope a. Furthermore, a protective plate 7 is attached to the stacked pallets 9 to prevent alkaline water from falling onto the PC board 1 at the bottom. Also, stacked pallets 9 on the decorative board 2
The height of the supports 10 of the stacked pallets 9 is set so that the bottom parts of the stacked pallets 9 do not touch each other. (Usually 30cm) FIG. 5 shows a front view of the third case in which the high temperature and high pressure steam curing method for PC board according to the present invention is implemented. FIG. 6 shows the same side view.

In the figure, 1 is a PC board made of a concrete board, to which a decorative board 2 made of tiles or the like is pasted, and the lowest PC board 1 is placed on a square pipe 5 with the decorative board 2 side facing upward. A distance block 6 is installed under one side of the square pipe 5 to create a slope a. 2nd stage and above
The PC board 1 is placed on the PC board support material 12. the bottom
The PC board support material 12 is provided with a slope a. A jig 13 for supporting the protection plate 7 is attached to the PC board support material 12 so as not to touch the decorative board 2 of the lower PC board 1.

Effects of the Invention In the high-temperature, high-pressure steam curing method for a concrete board to which a decorative board is attached according to the present invention, the protection board prevents alkaline water generated during curing from dripping onto the decorative surface of the lower PC board. Also, adding a slope to the PC board,
By not allowing the protective plate and the loading jig to directly touch the decorative surface, it is possible to prevent alkaline water from adhering to the decorative surface.
