Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite material board used for furniture such as sinks and cooking tables, for example, a composite material board such as a top plate with an aquarium.

Generally, furniture such as sinks and cooking tables have a water tank integrally attached to a board called a board.

As shown in FIG. 3, this water tank is equipped with a flange 14 at the edge of the entrance to prevent water collected on the top plate from leaking into the lower part of the slope from the gap between the top plate 12 and the water tank 13. A rubber packing 15 or a caulking agent was installed between the flange and the top plate surface 12 for sealing, and then the top plate was fixed with screws 16 and metal fittings 17 from the back side. However, with this method, the rubber packing and caulking agent deteriorate over time, and if the end plate is made of wood, the cut edge of the window hole absorbs moisture and expands near the machine surface, causing the water tank flange 1 and ceiling to swell. There was a drawback that a gap was created between the seal and the plate 12, and complete sealing could not be expected. In addition, in order to improve the sealing performance, it was necessary to tighten the screws with considerable force from the back side of the husband plate, making the installation process very time-consuming. The present invention eliminates these conventional drawbacks.
The purpose of this is to make it possible to easily connect the plate to the construction material such as an aquarium, and also to make the connection reliable and strong.

The embodiment will be described below with reference to the drawings, taking as an example a sink plate with a water tank.

In the figure, reference numeral 1 denotes a top plate, which is constructed by attaching melamine decorative paper lb to the surface of a particle board la, and has window holes 2 cut out at appropriate locations. Reference numeral 3 denotes a stainless steel water tank which is iron-fitted to this window hole, and a flange 3a that engages with the edge of the window hole 2 is press-formed on its closed edge.

This water tank 3 is formed in approximately the same shape as the window hole 2 so as to form an appropriate gap between the water tank 3 and the window hole 2 of the husband plate 1, and a plate material with a through hole 4 positioned in this gap. 5 is welded. Reference numeral 6 is a thermosetting resin that connects and integrates the husband plate 1 and the water tank 3, and is made of adhesive resin such as hard polyurethane, epoxy, polyester, etc.
At the same time, it covers the entire outer periphery of the aquarium 3.

This thermosetting resin 6 is applied by placing an upper mold with a predetermined gap above the top plate 1 and the water tank 3 (not shown), which have been set in advance in the lower mold. After pressing it against the flange 3a of 3 and fixing it in position, it is poured between the upper mold and the water tank 3 and hardened, and by this curing, both the water tank 3 and the husband plate 1 are joined and integrated. do.

At this time, this thermosetting resin 6 penetrates between the chips of the particle board la, which is the main body of the husband board 1, and is strongly bonded to the husband board 1 due to the adhesive properties of this resin itself, and the brackets Completely seal the hole edge cut. Also, this resin 6 is firmly bonded to the water tank 3 due to its adhesive property, but in this embodiment, the plate material 5 welded to the water tank 3
Since it enters into the through hole 6 and hardens, the provision of this plate material 5 makes the connection with the water tank 3, that is, the connection between the water tank 3 and the top plate 1, even stronger.
In addition, since the flange 3a of this water tank 3 is superimposed on the window hole traverse portion of the husband plate 1, there is no fear that it will fall off, and the connection is extremely reliable. Moreover, the overlapping of the flanges 3a dramatically increases the bonding area between the top plate 1 and the water tank 3, thereby further improving the bonding strength. In the above embodiment, a wooden material such as particle board was used for the top plate 1 that integrally connects the water tank 3, but this is shown as an example of a material that provides the strongest bond between the resin 6 and the top plate 1. It's not too much.

Similarly, in the above embodiment, a water tank-equipped plate in which a water tank is integrally bonded to a plate body is explained, but this is only one example product showing the composite material plate of the present invention as the easiest to understand type. be. As is clear from the above description of the embodiments, according to the present invention, a thermosetting resin can be interposed between a plate such as a husband plate and a backing material such as a water tank, and the resin can be hardened to connect the plate and the member. This thermosetting resin can be integrated into a single piece, significantly improving workability, and the thermosetting resin adheres tightly to the plate and components, and coats the cut surface of the plate to prevent damage caused by aging. As a result, a reliable bond between the plate and the backing material can be maintained for a long period of time.

In particular, in the present invention, since a part of the backing material is polymerized to the plate, the bonding area increases accordingly, and a strong bond is obtained, and when excessive force is applied, the presence of the polymerized portion allows the plate to There is also a great advantage in improving safety, such as being able to prevent dangerous situations such as parts falling out of the body.
