Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ceramic plate composite panel.

[Conventional technology]

Maximum dimensions of 2400 x 900 mm for finishing materials such as outer walls, inner walls and floors
The large ceramic plates are commercially available, but the thickness is 3 to 8 mm.
Since it is thin, it has low rigidity and is easily deformed by external force.

In addition, the main method of attachment to the frame is adhesion with an organic adhesive, but organic adhesives are uncertain with respect to deterioration over time, so at best they are for interior use, and are used for conditionally severe exteriors. Is being questioned. In addition, even in the case of interiors, since the installation is a wet construction method, not only the installation efficiency is bad, but also a specialized craftsman is required, so interior work could not be easily done by carpentry work.

There is a mounting method using screws, but this has not been implemented because the screw heads are visible and the product value declines.

[Problems to be solved by the device]

 The problems to be solved by the present invention are as follows.

(1). To provide a ceramic plate that has high rigidity and is hard to deform.

(2). Provide something that is easy to install.

(3). There is peeling at the adhesive interface of the ceramic plate,
To provide a composite panel in which a ceramic plate does not crack.

(4). To provide a fire resistant composite panel.

[Means for Solving the Problems]

The present invention is configured as follows to solve the above problems.

That is, the present invention is one in which a ceramic plate is bonded to one or both sides of a wood cement plate with polymer cement mortar.

The above-mentioned wood cement board is a board-shaped mixture of fibrous, rod-shaped, small piece-shaped or granular wood and cement mortar, and wood wool cement board, wood piece cement board, etc. are currently on the market.

[Action]

Since the present invention is a composite panel with a wood cement board, the rigidity is increased and warpage and twisting are prevented.

In addition, since the thickness becomes thicker, it is possible to use an embedded fastener such as a T-shaped fastener, which facilitates mounting.

Since the wood cement board has a structure in which timbers are three-dimensionally entangled with each other, it is tough and has deformation followability even though it is a cement product.

Therefore, even when the composite panel is deformed by an external force, peeling does not occur at the adhesive interface and cracks do not occur in the ceramic plate.

Not only ceramic plates, but also polymer cement mortar and wood cement plates have an inorganic material as a main component, and are excellent in fire resistance and long-term durability.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which a 3 mm thick ceramic large plate 1 having a thickness of 3 mm, a 50 mm thick wood cement plate 2 and a polymer using styrene-acrylic polymer emulsion and ordinary Portland cement. It is cemented with cement mortar 3 and has a groove 5 for using the T-type fastener 4 formed on the side edge of a wood cement board.

Since this embodiment is used as an outer wall, an inner wall, a floor ceiling plate, etc., it has the following features.

That is, since the composite panel has a large thickness, it has high rigidity and is difficult to be deformed. That is, warpage and twisting are prevented. Further, if the thickness is increased in this way, the cut groove 5 for using the T-type fastener 4 can be formed as shown in FIG.
Since it is a dry mounting method, the construction efficiency can be improved and the panel can be enlarged. That is, the construction can be rationalized.

Further, since the wood cement board 2 has a structure in which woods are three-dimensionally entangled with each other, it is a cement product and has toughness and deformation followability, and even when the composite panel is deformed by an external force, it is bonded. No peeling will occur at the interface and no crack will occur in the ceramic large plate 1.

Furthermore, since the ceramic large plate 1, the wood cement plate 2 and the polymer cement 3 all have an inorganic substance as a main component,
It has excellent fire resistance and long-term durability.

FIG. 2 shows a different embodiment of the wood cement board 2.
A glazed ceramic large plate 1 and a non-glaze ceramic large plate 1'are adhered to both sides of the same with polymer cement mortar 3,3. In this embodiment, the outer wall, inner wall,
Although it is used as a floor, a ceiling plate, etc., since it is attached on both sides, the rigidity is further increased, and it is possible to provide a product that does not completely warp or twist.

FIG. 3 shows a further different embodiment, in which glazed ceramic large plates 1,1 are adhered to both sides of a wood cement plate 2 with polymer cement mortars 3,3. In this case, the ceramic large plate is bonded so that the glazed surface is on the outside. This composite panel is used as a partition, a frontal wall, a training panel, etc. Since it is double-sided, it can not only provide the one with higher rigidity and perfect warpage and twist, but also the front and back surfaces. Both are useful as double-sided decorative plates, because the glazed surface of the large ceramic plate is exposed.
