Description

[Detailed description of the invention] Related to large plates used as parts of products.

A top plate with decorative veneer is used as a top plate for sink installation, but the flange of the sink is mounted on the top plate to connect the top plate and the sink, but due to the shape, water spilled onto the top plate. It has the disadvantage that it remains around the flange.

When a top plate and a sink are joined using adhesives, sealants, etc., water leaks from the joint, causing problems such as corrosion and swelling of the plywood, particle board, etc. used as the core material of the top plate. Openings such as doors and window frames were still insufficiently watertight, and improvements were needed.

The present invention provides a top plate that enables an installation method that does not have these drawbacks, and includes a top plate material in which a resin layer formed in the notch of a core material and a decorative board are integrated on the top of the core material. The present invention relates to a top plate characterized in that the decorative board and the resin layer are cut in the vicinity of the connecting portion between the core material and the resin layer.

Next, the present invention will be explained with reference to drawings of one embodiment.
) is adhered to the melamine decorative board (
A resin layer (5) is formed on the back side of 2) to make the top plate material. The melamine decorative board (2) and the resin layer (5) are cut in the vicinity of the connection part between the plywood (1) and the resin layer (5) of the top plate material (11) to form the top plate ( 12
). FIG. 4 shows a structure in which a sink (7) is attached to the top plate.

In the above example, a melamine decorative board is used as the decorative board, but other decorative boards such as diallyl phthalate resin decorative board, polyester) V resin decorative board, reinforced planutic decorative board, metal decorative board, etc. The vicinity of the end of the decorative board may be bent if necessary. In addition to plywood, particle board, fiberboard, etc., molded or hollow panel materials can also be used for the core material. Moreover, four parts may be provided in the cross section of the notch part of the core material in order to improve the bonding strength with the resin layer. Materials for forming resin PJ include thermosetting resins with good adhesion properties such as urethane resin, epoxy resin, unsaturated polymer resin, persimmon resin, etc., but in order to improve the hardness of the resin layer, various Filling agents may be mixed into the resin. Thickness of resin Aha d
The selection is made at the appropriate time based on the thickness of the core material, the design of the large plate, the thickness of the mounting parts, etc.

In the top plate of the present invention, since the resin layer is integrally formed in the opening, the opening is reinforced and becomes thicker, and its water resistance and aging resistance are significantly improved. Therefore, if the flange of the sink, the mounting part of the stove, or the glass plate, etc. are bonded to the underside of the tree layer with adhesive, sealant, etc., furniture parts such as sinks and the like will have a high elasticity and durability. door,
Architectural components dedicated to window frames can be obtained on the surface side.

Claims (1)

[Claims] From a top plate material in which a resin layer formed in the notch of the core material and a decorative board are integrated on the top of the core material, the decorative board and the resin layer are cut near the connection between the core material and the resin layer. A top plate characterized by being processed.
