Description

[Detailed description of the invention] This invention relates to a top plate mainly used for kitchen counters, etc., and by reinforcing the edge of the wood in the part where the punched hole is formed, the strength against mechanical or thermal effects is reduced. It is designed to prevent this.

In general, the top plate that makes up the counter of kitchen equipment is made of a material that can withstand thermal or mechanical conditions sufficiently when installing heating appliances such as gas stoves, hot plates, or ovens, and aquarium appliances for sinks. is required to be used.

Conventionally, this type of top plate has been made of a resin molded product containing a filler, and in order to install the various instruments mentioned above, a rectangular cut-out hole is formed in the top plate body to match the external shape of the instrument. There is a known device in which a hole is formed and each instrument is fitted into the hole.

However, in the case of a top plate of such a conventional structure, for example, one in which a back guard is integrally formed on the back side, the holes into which various instruments are fitted are simply cut into squares. Since the butt end surface is not processed in any way, the strength is weakened thermally or mechanically as the cross-sectional area of the surface facing the depth direction of the punched hole portion is reduced.
For this reason, there were various concerns about the installation of the top plate, other handling, transportation, and abnormal heating (overheating) of the heating equipment.

This invention is aimed at solving the above-mentioned conventional drawbacks, and will be explained below based on the illustrated embodiment.

As shown in FIGS. 1 to 3, reference numeral 1 in the figures is a top plate main body made of a filled resin molded product constituting a kitchen counter obtained by a manufacturing method described later. The top plate body 1
has a back guard 2 that is integrally formed on the back side, and a rectangular cut-out hole 3 into which a heating appliance H such as a gas stove or a hot plate is inserted is cut out approximately in the center of the back guard 2. It is formed. Approximately 4 pieces of FRP4 is applied to the upper and lower surfaces around the wood end 3a of the punched hole part 3.
It is attached integrally with a thickness of about 5 mm.

That is, in order to manufacture the top plate according to the above-mentioned invention, a hand lay-up molding method is adopted, and punch holes 3 are cut and formed in a separately manufactured top plate body 1 made of resin containing a filler. For example, a curing agent is added to the unsaturated polyester resin liquid on the upper and lower surfaces around the butt end 3a of the punch hole 3.
Raw material for FRP molding (uncured or semi-cured) made by impregnating reinforcing fibers such as glass mat or cloth with liquid matrix resin containing an appropriate amount of accelerator is laminated by hand lay-up and cured. This is obtained by integrally adding FRP 4 as a reinforcing layer to the upper and lower surfaces around the butt end 3a of the punched hole part 3 by performing trimming and finishing processes.

4 and 5 show another embodiment of this invention, in which an FRP layer 4 attached around the end 3a of the punched hole 3 of the top plate 1 is attached to one side of the upper or lower surface. It has the following configuration.

In the above-mentioned examples, uncured or semi-cured FRP molding material was used as a means for attaching the FRP layer around the end of the punched hole.
As another means, it may be pasted in advance using FRP as a hardening agent and an adhesive, and the selection thereof is arbitrary.

As mentioned above, according to this invention, FRP is integrally attached around the end of the cutout of the top plate body to reinforce the end of the cutout, so the strength due to the formation of the cutout is increased. The lack of strength is reinforced by FRP integrated around the end of the butt end, which prevents accidents such as damage and cracks caused by insufficient strength during handling such as attaching the top plate, transportation, loading, and abnormal use (overheating with heating equipment). This can be completely prevented, and since the FRP is integrated into the already formed top plate body, there is no distortion due to differences in curing shrinkage rate, and the strength is improved both thermally and mechanically. It is possible to obtain a top plate with a certain punched hole.
