ない。Conventionally, this type of top plate has been made of a resin molded product containing a filler, and when installing the various appliances mentioned in ``2'', a rectangular shape according to the external shape of the appliance is attached to the top plate body. If a hole is formed and each device is fitted into the hole, for example, if two back guards are integrally formed on the back side, various devices can be fitted into the hole. Since the punched hole part is simply cut into a square shape and the wood end surface is not processed, the cross-sectional area of the surface facing the depth direction of the punched hole part is As the temperature decreases, the thermal or mechanical strength becomes weaker, and therefore there are various concerns about the strength of the product, such as when installing the top plate, handling it, transporting it, or overheating it with a heating device. there were. Therefore, as a means to compensate for the drawbacks of the conventional structure described above, an edge frame material made of hardened fiber-reinforced plastic (hereinafter abbreviated as FRP) was attached to the circumferential surface of the cutout of the top plate body using adhesive. However, when attaching the edge frame material, if the end surface is not finished with a clean, flat surface during the cutting process of the punched hole, the thickness of the adhesive may become uneven. It is necessary to apply pressure to the edge frame material during the gluing process, because it is not possible to adhere the edge frame material accurately and neatly), and this pressure is applied at a place where the part to apply pressure is the wood end surface. However, it is extremely difficult to perform in actual practice, and is prone to poor adhesion, making it unsuitable for practical use.

み込むように断面フ字形に形成されている。As shown in FIGS. 1 and 2, reference numeral 1 in the figures is a top plate main body made of a filled resin molded product constituting a quintin counter obtained by a manufacturing method described later. The top plate main body 1 has a back guard 2 integrally formed on the back side thereof, and has a rectangular punch hole approximately in the center thereof into which a heating appliance 14 such as a gas stove or a hot plate is fitted. The portion 3 is formed by cutting around. FRP 4 is integrally attached to the wood end surface 3a of the punched hole portion 3 with a thickness of about 4 to 5 mm, and the FRP 4 reinforcing the wood end surface is attached to the wood end surface 3a of the punched hole portion. The cross section is formed into a F-shape so as to sandwich the entire circumferential surface.

る。That is, in order to manufacture the above-mentioned top plate according to the present invention, a hand lay-up molding method is adopted, and punch holes 3 are cut and formed in a separately molded resin top plate body 1 containing a filler. The butt end surface 3a of the punched hole portion 3
After applying a matrix liquid resin to the end surface 3a, for example, a liquid resin for matrix, which is an unsaturated polyester resin liquid mixed with a curing agent and an accelerator in appropriate amounts, is applied to reinforcing fibers obtained by cutting a glass mat into appropriate widths and lengths.

]" Raw material for molding (uncured or semi-cured) is laminated by hand layup, air bubbles in the raw material for FRP molding are defoamed by rolling, and then left at room temperature for 4 hours.Next, this is left at room temperature for 4 hours. Place it in a heating chamber and perform post-curing (4 hours at 80°C) to harden it, then perform trimming and finishing.
This is obtained by integrating FRP4 as a reinforcing layer into a.

とができるものである。As described above, according to the present invention, FRP is integrally attached to the end surface of the punched hole portion of the top plate main body,
Since it is intended to reinforce the wood end surface, the lack of strength due to the formation of punched holes is reinforced by the FRP integrated into the wood end surface, which prevents handling such as attaching the top plate, transportation, loading, and abnormal use (overuse with heating equipment). It is possible to completely prevent accidents such as damage and cracks caused by insufficient strength during heating), etc., and since the FRP is integrated into the already formed top plate body, distortion due to differences in curing shrinkage rate can be completely prevented. Accordingly, it is possible to obtain a top plate having a punched hole portion that is thermally and mechanically strong without the generation of .
