Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a one-tub plate mainly used for kitchen counters, etc., and in particular, by devising a molding treatment means for the end surface of the punched hole forming part, mechanical or This material has a layer that prevents the strength from decreasing due to thermal effects.

In fact, the plates 1 to 3 that make up the counter of the bookstore equipment are based on the thermal or mechanical conditions that apply to heating appliances such as Gascon II, pot plates or ovens, and water tank appliances for sinks. It is required to use materials that are sufficiently durable.

Conventionally, in this type of top plate 1 to 2, a resin molded product containing a filler has been used, and the smell C for installing various instruments as described above has been made by attaching the outer shape of the instrument to the top plate body. It is known to have a rectangular punch hole corresponding to the size of the vehicle, and to fit and hold each instrument into the hole.

However, such a conventional top brake 1-
1. For example, in cases where the back guard is integrally formed on the back side, the hole portion into which various instruments are fitted is simply cut into a square shape, and the cut end surface, ie Since the end surface is not subjected to capillary treatment, the cross-sectional area of the surface facing the depth direction of the hole forming part is reduced, and the strength is weakened thermally or mechanically. -1- There were considerable concerns about the strength of the product, including installation and handling, shock during transportation, and abnormal heating (overheating) of the heating equipment.

Therefore, as a means of compensating for the drawbacks of the conventionally structured top plate described above, hardened fiber-reinforced plastic (
It is possible to obtain a reinforcing effect by fixing an edge frame made of FRP (hereinafter abbreviated as FRP) with adhesive. During the cutting process, the cut end surface, which will be the 1'' side of the wood, is finished with a clean, flat surface (if it is not done, the adhesive will have uneven thickness, and the edge frame will not be able to be glued neatly and neatly). Not only is this not possible, but in the gluing process, it is necessary to apply pressure to the edge frame on the side of the wood (11). Arida G
At present, it is very difficult to use in actual work, tends to cause poor adhesion, and is not suitable for practical use.

This invention has been defended in light of the various problems mentioned above, and uses a mold to make a resin containing a filler having a hole into which a heating device such as a gas conditioner 1 or a device such as a water heater (I) is inserted. When manufacturing 1~Tubu Plate 1~, when injecting and filling the uncured or semi-cured top plate molding resin into the mold, the handling holes distributed in advance in the mold are used. By fitting an edge frame made of hardened FRP that forms the butt end surface around the dummy for molding the part and integrally molding it using a conventional method, the butt end surface of the punched hole part of the tongue plate can be reinforced. It is characterized by the fact that it does not have 1j in RP.

Hereinafter, this invention will be explained based on illustrated embodiments.
As shown in FIGS. 1 and 2, 1 in the figure is a top plate made of a resin molded product containing a filling material that constitutes a kitchen counter manufactured by the manufacturing means described later.
It is the main body. The top plate main body 1 has a back guard 2 integrally formed on its back side, and approximately in the center thereof has a rectangular cutout into which a heating appliance H such as a gas stove or a hot plate is inserted. In addition to the hole 3 formed therein, the butt end surface 3 of the punched hole 3 is
a is integrally formed with an FRP layer 4 with a thickness of approximately 4 to 5III11.

That is, in order to manufacture the I-tube plate having the above-mentioned configuration according to the present invention, as shown in FIGS. When placing the rubber punch-hole molding dummy 11 at the position M-j, a cured FR is placed around the dummy 11 via a mold release agent.
Insert the edge frame 12 into the mold (see Figure 3), then inject the uncured or semi-cured top play 1 to molding filler-containing resin 13 into the mold 10. (Refer to Figure 4 for filling) After hardening, the molded product is removed from the mold (see Figure 4).
(see Figure 5), by removing the dummy 11, the first
Top play as shown in Figures and Figure 2]
F.

In the above example, the resin for the matrix of the raw material for molding (FRI) is prepared by combining the top play 1 and molding material I# with the monthly resin in advance to achieve a hardening balance! When using semi-hardened prepreg as a green material for FRP molding, it is important to keep it at a certain temperature (= J t) using a tool such as ] to prevent voids. laminate around the dummy for forming the punched hole while eliminating the

As explained above, this invention is a resin containing a full 111 material having punched holes! When molding 3j1-tube brake 1~, a hardened FRP green frame that forms the end surface was attached in advance around the dummy for forming the punched hole, and both were hardened and integrated at the same time as molding. It is expected that the reliability and strength of adhesion will be improved compared to FRP reinforcing methods for the butt end surface using adhesives such as . In terms of durability, it is possible to obtain a one-edge plate that is superior in durability.
